We are offering 1,326,175 shares of common stock, together with the Series A-5 warrants to purchase 1,326,175 shares of common stock (the “Series A-5 warrants”) and Series A-6 warrants to purchase 1,326,175 shares of common stock (the “Series A-6 warrants,” and together with the Series A-5 warrants, the “Series A warrants”), pursuant to this prospectus. The combined public offering price for each share of common stock, together with the accompanying Series A warrants, is $1.15 . The shares of common stock and Series A warrants will be separately issued, but the shares of common stock and Series A warrants will be issued to purchasers in the ratio of one to one. Each Series A-5 warrant will have an exercise price of $1.15 per share, will be exercisable upon issuance and will expire May 1, 2028. Each Series A-6 warrant will have an exercise price of $1.15 per share, will be exercisable upon issuance and will expire on November 1, 2024.

We are also offering 2,152,087 pre-funded warrants, or the Series D pre-funded warrants (and collectively with the Series A warrants, the “warrants”), to those purchasers whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering in lieu of the shares of our common stock that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%). Each Series D pre-funded warrant will be exercisable for one share of common stock at an exercise price of $0.01 per share. Each Series D pre-funded warrant is being issued together with the same Series A warrants described above being issued with each share of common stock. The combined public offering price for each such Series D pre-funded warrant, together with the Series A warrants, is $1.14. Each Series D pre-funded warrant will be exercisable upon issuance and may be exercised at any time until all of the pre-funded warrants are exercised in full. The Series D pre-funded warrants and Series A warrants are immediately separable and will be issued separately in this offering, but the Series D pre-funded warrants and Series A warrants will be issued to purchasers in the ratio of one to one. This prospectus also relates to the offering of the shares of common stock issuable upon exercise of the Series A Warrants, Series D Pre-Funded Warrants and Placement Agent Warrants.

There is no established public trading market for the warrants, and we do not expect a market to develop. We do not intend to apply for listing of the warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the warrants will be limited.

This offering will terminate on May 10, 2023, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share (or pre-funded warrant) and Series A warrants will be fixed for the duration of this offering.

PROSPECTUS SUMMARY

This summary highlights information contained in other parts of this prospectus and in the documents we incorporate by reference. Because it is only a summary, it does not contain all of the information that you should consider before investing in our securities and it is qualified in its entirety by, and should be read in conjunction with, the more detailed information appearing elsewhere in this prospectus, any applicable free writing prospectus and the documents incorporated by reference herein. You should read all such documents carefully, especially the risk factors and our consolidated financial statements and the related notes included or incorporated by reference herein, before deciding to buy our securities. Unless the context requires otherwise, references in this prospectus to “Baudax,” “we,” “us” and “our” refer to Baudax Bio, Inc. and our subsidiaries.

Overview

We are a pharmaceutical company primarily focused on innovative products for hospital and related settings. We believe that we can bring valuable therapeutic options for patients, prescribers and payers to the hospital and related markets.

We hold exclusive global rights to two new molecular entities, which are centrally acting Neuromuscular Blocking Agents, or NMBs, BX1000, an intermediate duration of action NMB currently undergoing a Phase II clinical trial, and BX2000, an ultra-short acting NMB currently undergoing a Phase I dose escalation trial. In addition, BX3000 is an agent that is expected to rapidly reverse BX1000 and BX2000 blockade, which is currently being evaluated in preclinical studies intended to support an IND filing in 2023. All three agents are licensed from Cornell University. We believe these blocking agents allow for a rapid onset of centrally acting neuromuscular blockade, followed by a rapid reversal of the neuromuscular blockade with BX3000. These novel agents have the potential to meaningfully reduce time to onset of blocking and of reversal of blockade, reducing time in operating rooms or post operative suites, resulting in potential clinical and cost advantages, as well as valuable cost savings for hospitals and ambulatory surgical centers.

In mid-2020, we launched our first commercial product, ANJESO, in the United States. ANJESO is the first and only 24-hour, intravenous, or IV, analgesia agent. ANJESO is a cyclooxygenase-2, or COX-2, preferential, non-steroidal anti-inflammatory, or NSAID, for the management of moderate to severe pain, which could be administered alone or in combination with other non-NSAID analgesics. We discontinued commercial sales of ANJESO in December of 2022.

Our costs have consisted primarily of expenses incurred in conducting our manufacturing and commercialization of ANJESO, which was discontinued in December of 2022, as well as public company and personnel costs, clinical trials and preclinical studies, regulatory activities and manufacturing costs for our NMB blocking and reversal agents. We expect to incur operating losses for at least the next several years. We expect substantially all of our operating losses to result from costs incurred in connection with our development programs, including our clinical, nonclinical and formulation development, preclinical and manufacturing related activities. Our expenses over the next several years are expected to primarily relate to developing our product candidates. In addition, we may incur costs associated with the acquisition or in-license of products and successful commercialization of the acquired or in-licensed products.

Recent Developments

Going Concern

Our management has concluded that substantial doubt exists about our ability to continue as a going concern for one year from the date of this prospectus. We do not expect that the net proceeds of $3.4 million from this offering will be sufficient to allow us to continue as a going concern for one year from the date of this prospectus. The net proceeds of $3.4 million from this offering, together with our existing cash and cash equivalents, will meet our capital needs into the third quarter of 2023.

Top-Line Results from Phase 2 Clinical Trial of BX1000

On April 25, 2023, we reported positive top-line results from its Phase 2 clinical trial of BX1000 in patients undergoing elective surgery. Results of the study showed that BX1000 met the primary endpoint of readiness for intubation (evaluated as “Good” or “Excellent”) at all dose levels assessed. No severe adverse events were observed in any dose regimen.

The BX1000 Phase 2 surgery trial is a randomized, double-blind, active-controlled clinical trial comparing three different doses of BX1000 to a standard dose of 0.6mg/kg rocuronium in a planned clinical trial of 80 adult patients undergoing elective surgery utilizing total intravenous anesthesia. A total of 81 patients were randomized to the four treatment groups. One patient discontinued early and did not receive a study drug. A total of 80 patients were treated. Each BX1000 dose cohort had 20 evaluable patients and the rocuronium cohort had 19 evaluable patients (one subject in this arm experienced a delay in intubating condition assessment.) The primary efficacy endpoint of the study was the proportion of patients that met criteria for Good or Excellent intubating conditions using a standardized scale. Additionally, the clinical trial evaluated the safety and tolerability profile of BX1000 and rocuronium in this patient population.

Results showed that all patients in three BX1000 study cohorts were observed to have met the criteria for Good or Excellent intubating conditions at 60 seconds. There was evidence of a dose-response across the three doses of BX1000, and the degree of blockade for the highest dose group appears comparable to that of the “standard” dose of rocuronium (0.6 mg/kg) employed in the study. Study treatments were generally well tolerated, with no occurrence of severe or serious adverse events. The frequency and severity of adverse events was similar across all four dose groups, and no notable events were aggregated in any one dose group.

Risks Associated with this Offering

This offering is subject to numerous risks and uncertainties, including those highlighted in the section entitled “Risk Factors” immediately following this prospectus summary and the similarly titled sections in the documents incorporated by reference into this prospectus. These risks include, but are not limited to, the following:

• Management will have broad discretion as to the use of the proceeds from this offering, and we may not use the proceeds effectively.

• You will experience immediate dilution in the book value per share of the common stock purchased in the offering.

• Issuances of shares of common stock or securities convertible into or exercisable for shares of common stock following this offering, as well as the exercise of options outstanding, will dilute your ownership interests and may adversely affect the future market price of our common stock.

• A substantial number of shares of common stock may be sold in the market following this offering, which may depress the market price for our common stock.

• There is no public market for the warrants being offered in this offering.

• The holders of warrants purchased in this offering will have no rights as common shareholders until such holders exercise their warrants and acquire our common shares, except as set forth in the warrants.

Implications of Being an Emerging Growth Company

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, as amended, or JOBS Act. We will remain an emerging growth company until December 31, 2024, unless our gross revenue exceeds $1.235 billion in any fiscal year before that date, we issue more than $1.0 billion of non-convertible debt in any three-year period before that date or the market value of our common stock held

6

by non-affiliates exceeds $700.0 million as of the last business day of the second fiscal quarter of any fiscal year before that date. We have elected to take advantage of certain of the scaled disclosure available for emerging growth companies in this prospectus as well as our filings under the Exchange Act of 1934, or the Exchange Act, including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation and financial statements in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote to approve executive compensation and shareholder approval of any golden parachute payments not previously approved. We will take advantage of these reporting exemptions until we are no longer an “emerging growth company.” The JOBS Act provides that an “emerging growth company” can take advantage of an extended transition period for complying with new or revised accounting standards. We have irrevocably elected not to avail ourselves of this exemption and, therefore, we are subject to the same new or revised accounting standards as other public companies that are not “emerging growth companies.”

RISK FACTORS

An investment in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should carefully consider the risks described below and those discussed under the Section captioned “Risk Factors” contained in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC and which is incorporated by reference in this prospectus, together with other information in this prospectus, the information and documents incorporated by reference herein, and in any free writing prospectus that we have authorized for use in connection with this offering. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section above entitled “Forward-Looking Statements.”

Risks Related to This Offering

Management will have broad discretion as to the use of the proceeds from this offering, and we may not use the proceeds effectively.

Our management will have broad discretion with respect to the use of proceeds of this offering, including for any of the purposes described in the section of this prospectus entitled “Use of Proceeds.” You will be relying on the judgment of our management regarding the application of the proceeds of this offering. The results and effectiveness of the use of proceeds are uncertain, and we could spend the proceeds in ways that you do not agree with or that do not improve our results of operations or enhance the value of our common stock. Our failure to apply these funds effectively could harm our business, delay the development of our pipeline product candidates and cause the price of our common stock to decline.

You will experience immediate dilution in the book value per share of the common stock purchased in the offering.

Since the public offering price of our common stock in this offering is substantially higher than the net tangible book value per share of our outstanding common stock outstanding prior to this offering, you will suffer dilution in the book value of the common stock you purchase in this offering. The exercise of outstanding stock options and warrants, including warrants sold in this offering and the placement agent warrants, may result in further dilution of your investment. See the section titled “Dilution” for a more detailed discussion of the dilution you will incur if you purchase shares in this offering.

Issuances of shares of common stock or securities convertible into or exercisable for shares of common stock following this offering, as well as the exercise of options outstanding, will dilute your ownership interests and may adversely affect the future market price of our common stock.

We will need additional capital to fund the development, registration and commercialization of our product candidates. We may seek additional capital through a combination of private and public equity offerings, debt financings, strategic partnerships and alliances and licensing arrangements, which may cause your ownership interest to be diluted. In addition, we have a significant number of warrants to purchase shares of our common stock outstanding. If these securities are exercised, you may incur further dilution. Moreover, to the extent that we issue additional options to purchase, or securities convertible into, exercisable or exchangeable for, shares of our common stock in the future and those options or other securities are exercised, converted or exchanged, shareholders may experience further dilution.

10

A substantial number of shares of common stock may be sold in the market following this offering, which may depress the market price for our common stock.

Sales of a substantial number of shares of our common stock in the public market following this offering could cause the market price of our common stock to decline. A substantial majority of the outstanding shares of our

common stock are, and the shares of common stock sold in this offering upon issuance will be, freely tradable without restriction or further registration under the Securities Act of 1933, as amended, or the Securities Act.

Upon completion of this offering, based on our shares outstanding as of April 15, 2023, we will have 6,063,964 shares of common stock outstanding, assuming full exercise of the Series D pre-funded warrants sold in this offering, which may be resold into the public market immediately without restriction, unless owned or purchased by our “affiliates” as that term is defined in Rule 144 under the Securities Act.

As of April 15, 2023, there were approximately 11,756 shares subject to outstanding options and restricted stock unit awards or that are otherwise issuable under our equity compensation plans, all of which shares we have registered or will register under the Securities Act on a registration statement on Form S-8. The registered shares can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates, to the extent applicable. As of April 15, 2023, we had outstanding warrants exercisable for 2,672,798 shares of common stock with a weighted-average exercise price of $9.92 per share. The shares of our common stock underlying such warrants will, upon issuance, be freely tradeable without restriction or further registration under the Securities Act.

There is no public market for the warrants being offered in this offering.

There is no established public trading market for the warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the warrants on any securities exchange or nationally recognized trading system, including the Nasdaq Capital Market. Without an active market, the liquidity of the warrants will be limited.

The holders of warrants purchased in this offering will have no rights as common shareholders until such holders exercise their warrants and acquires our common shares, except as set forth in the warrants.

Until a holder of warrants acquires the shares of common stock upon exercise of the warrants, such holder will have no rights with respect to the shares of common stock underlying such warrants, except as set forth in the warrants. Upon exercise of the warrants, holders will be entitled to exercise the rights of common shareholders only as to matters for which the record date occurs after the exercise date.

The warrants are speculative in nature.

The warrants do not confer any rights of common stock ownership on their holders, such as voting rights, but rather merely represent the right to acquire shares of common stock at a fixed price for a limited period of time. Specifically, holders of the warrants may exercise their right to acquire the common stock and pay an exercise price of $1.15 per share for the Series A-5 warrants, $1.15 per share for the Series A-6 warrants and $0.01 per share for the Series D pre-funded warrants, subject to certain adjustments, commencing immediately upon issuance and for the Series A-5 warrants, until May 1, 2028, after which period any unexercised Series A-5 warrants will expire and have no further value and for the Series A-6 warrants, until November 1, 2024, after which period any unexercised Series A-6 warrants will expire and have no further value. There can be no assurance that the market price of the common stock will ever equal or exceed the exercise price of the warrants, and consequently, it may not ever be profitable for holders of the warrants to exercise the warrants.

The market price for our common stock has been volatile and may continue to fluctuate or may decline significantly in the future.

An active, liquid and orderly market for our common stock may not be sustained, which could depress the trading price of our common stock or cause it to continue to be highly volatile or subject to wide fluctuations.

11

Some of the factors that could negatively affect our share price or result in fluctuations in the price or trading volume of our common stock include, among other things:

• the commencement, enrollment, or results of our current and future preclinical studies and clinical trials, and the results of trials of our competitors or those of other companies in our market sector;

• regulatory approval of our product candidates, or limitations to specific label indications or patient populations for its use, or changes or delays in the regulatory review process;

• manufacturing, supply or distribution delays or shortages;

• our ability to identify and successfully acquire or in-license new product candidates on acceptable terms;

• FDA, state or international regulatory actions, including actions on regulatory applications any of our product candidates;

• legislative or regulatory changes;

• judicial pronouncements interpreting laws and regulations;

• changes in government programs;

• announcements of new products, services or technologies, commercial relationships, acquisitions or other events by us or our competitors;

• market conditions in the pharmaceutical and biotechnology sectors;

• fluctuations in stock market prices and trading volumes of similar companies;

• changes in accounting principles;

• litigation or public concern about the safety of our product candidates or similar product candidates;

• sales of large blocks of our common stock, including sales by our executive officers, directors and significant shareholders;

• our ability to obtain additional financing to advance our development operations;

• our announcement of financing transactions, including debt, convertible notes, warrant exchanges, etc.;

• our ability to regain and maintain compliance with the listing standard of Nasdaq;

• the continued negative effects of the COVID-19 pandemic on the global economy; and

• actions by institutional shareholders.

These broad market and industry factors may decrease the market price of our common stock, regardless of our actual operating performance. The stock market in general has from time to time experienced extreme price and volume fluctuations, including recently. For example, on March 10, 2023, the Federal Deposit Insurance Corporation took control and was appointed receiver of Silicon Valley Bank, or SVB. The financing uncertainty pharmaceutical, biotechnology and medical technology companies may now face as a result of SVB’s entry into receivership may cause significant volatility with respect to pharmaceutical, biotechnology, and medical technology company stocks, which in turn could negatively impact the trading price of our common stock. In addition, in the past, following periods of volatility in the overall market and decreases in the market price of a company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

This is a best efforts offering, no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans, including our near-term business plans.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the

12

purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth herein. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations, including our near-term continued operations. Thus, we may not raise the amount of capital we believe is required for our operations in the short-term and may need to raise additional funds to complete such short-term operations. Such additional fundraises may not be available or available on terms acceptable to us.

Risks Related to Our Finances and Capital Requirements

Our losses, negative cash flows from operations and accumulated deficit raise substantial doubt about our ability to continue as a going concern absent obtaining adequate new debt or equity financings.

Management has concluded that substantial doubt exists about our ability to continue as a going concern for the next twelve months from the date hereof. As of December 31, 2022, we had an accumulated deficit of $190.9 million, cash and cash equivalents of $5.3 million and current liabilities of $21.5 million. Based on available resources, we believe that, prior to this offering, our cash and cash equivalents on hand would be sufficient to fund our currently anticipated operating and capital requirements into the second quarter of 2023, however, our current capital resources are not sufficient to support our planned operations for the next twelve months from the date hereof. We believe that based on the net proceeds of $3.4 million that we will receive from this offering, after deducting the placement agent fees and estimated offering expenses payable by us, that our cash and cash equivalents on hand will be sufficient to fund our currently anticipated operating and capital requirements into the third quarter of 2023.

We expect to continue to incur losses for the foreseeable future as we continue our efforts to develop our current and future product candidates. We have also incurred significant indebtedness. As of December 31, 2022, we had an outstanding balance of $7.8 million under our credit facility with MAM Eagle Lender. These factors, individually and collectively, raise substantial doubt about our ability to continue as a going concern, and therefore, could materially limit our ability to raise additional funds through an issuance of debt or equity securities or otherwise.

There can be no assurance that we will be able to raise sufficient additional capital on acceptable terms or at all. Additionally, if we are unable to regain compliance with the listing standards of Nasdaq, our common stock may become delisted, which could have a material adverse effect on the liquidity of our common stock and our ability to raise funding. If such additional financing is not available on satisfactory terms, or is not available in sufficient amounts, we may be required to delay, limit or eliminate the development of business opportunities and our ability to achieve our business objectives, our competitiveness, and our business, financial condition and results of operations will be materially adversely affected. In addition, the impact of the ongoing COVID-19 pandemic on the global financial markets may reduce our ability to access capital, which could negatively affect our liquidity and ability to continue as a going concern. In addition, the perception that we may not be able to continue as a going concern may cause others to choose not to deal with us due to concerns about our ability to meet our contractual obligations.

Our forecast of the period of time through which our financial resources will be adequate to support our operating requirements is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section and Part I, Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on February 23, 2023. We have based this estimate on a number of assumptions that may prove to be wrong and changing circumstances beyond our control may cause us to consume capital more rapidly than we currently anticipate. Our inability to obtain additional funding when we need it could seriously harm our business.

13

If we are unable to regain compliance with the listing standards of Nasdaq, our common stock may become delisted, which could have a material adverse effect on the liquidity of our common stock and our ability to raise funding.

The listing standards of the Nasdaq Capital Market provide that a company, in order to qualify for continued listing, must maintain stockholders’ equity of at least $2,500,000, or the Stockholders’ Equity Requirement pursuant to Nasdaq Listing Rule 5550(b)(1), or Rule 5550(b)(1). On November 15, 2022, we received notice from Nasdaq, or the Notice, advising us that we are not in compliance with the Stockholders’ Equity Requirement. Pursuant to the Notice, Nasdaq gave us until December 30, 2022, to submit to Nasdaq a plan to regain compliance. On January 17, 2023, Nasdaq informed us that our plan has been accepted and we have until May 15, 2023 to comply with such plan.

There can be no assurance that we will be able to maintain compliance with 5550(b)(1) or the other Nasdaq listing requirements. If we do not maintain compliance with the Nasdaq continuing listing requirements, our common stock will be delisted from the Nasdaq Capital Market and it could be more difficult to buy or sell our securities and to obtain accurate quotations, and the price of our common stock could suffer a material decline. In addition, a delisting would impair our ability to raise capital through the public markets, could deter broker-dealers from making a market in or otherwise seeking or generating interest in our securities and might deter certain institutions and persons from investing in our securities at all.

14

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $3.4 million, after deducting the placement agent fees and estimated offering expenses payable by us, and assuming full exercise of the Series D pre-funded warrants being issued in this offering and no exercise of the Series A warrants being issued in this offering.

These estimates exclude the proceeds, if any, from the exercise of Series A warrants issued in this offering. If all of the Series A-5 warrants issued in this offering were to be exercised in cash at the exercise price of $1.15 per share of common stock, we would receive additional proceeds of approximately $4.0 million and if all of the Series A-6 warrants issued in this offering were to be exercised in cash at an exercise price of $1.15 per share of common stock, we would receive additional proceeds of approximately $4.0 million. We cannot predict when or if these Series A warrants will be exercised. It is possible that these Series A warrants may expire and may never be exercised. Additionally, the Series A warrants contain a cashless exercise provision that permit exercise of Series A warrants on a cashless basis at any time where there is no effective registration statement under the Securities Act covering the issuance of the underlying shares.

We intend to use the net proceeds of this offering for pipeline development activities and general corporate purposes. General corporate purposes may include, and are not limited to, costs associated with, research and development costs, manufacturing costs, the acquisition or licensing of other businesses, products or product candidates, working capital and capital expenditures. These expected uses represent our intentions based upon our current plans and business conditions, which could change in the future as our plans and business conditions evolve. The amounts and timing of our actual expenditures may vary significantly depending on numerous factors, including the progress of our development, the status of and results from clinical trials, as well as any new collaborations that we may enter into with third parties for our product candidates, the commercialization of our products or our product candidates, if approved, and any unforeseen cash needs. As a result, our management will have broad discretion in the application of the net proceeds from this offering, and the investors will be relying on the judgment of our management regarding the application of the net proceeds from this offering. Pending application of the net proceeds as described above, we intend to invest the net proceeds of this offering in short-term, investment-grade, interest-bearing securities.

15

DIVIDEND POLICY

We have never declared or paid any cash dividends on our common stock and our ability to pay cash dividends is currently restricted by the terms of our credit facility with MAM Eagle Lender, LLC. We currently intend to retain all available funds and any future earnings, if any, to fund the development and expansion of our business and we do not anticipate paying any cash dividends in the foreseeable future. Any future determination to pay dividends on our common stock will be made at the discretion of our board of directors and will depend on various factors, including applicable laws, our results of operations, financial condition, future prospects, anticipated cash needs, plans for expansion and any other factors deemed relevant by our board of directors.

16

DILUTION

If you invest in our common stock, your interest will be immediately diluted to the extent of the difference between the public offering price per share and the as adjusted net tangible book value per share of our common stock after this offering. Net tangible book value per share represents our total tangible assets less total liabilities, divided by the number of shares of our common stock outstanding.

As of December 31, 2022, our net tangible book value was $(26.4) million, or $(16.24) per share of common stock, based on 1,623,913 shares of common stock outstanding as of December 31, 2022. Our pro forma net tangible book value as of December 31, 2022 was approximately $(22.0) million, or $(8.52) per share, after giving effect to the exercise of warrants to purchase 961,787 shares of our common stock for gross proceeds of $4.3 million during the first quarter of 2023, or the Warrant Exercise.

After giving effect to the sale of 1,326,175 shares of our common stock and accompanying Series A warrants at a public offering price per share of common stock of $1.15, the sales of the Series D pre-funded warrants to purchase 2,152,087 shares of common stock and accompanying Series A warrants at a public offering price of $1.14, and assuming full exercise of the Series D pre-funded warrants at an exercise price of $0.01 per Series pre-funded warrant, and after deducting the estimated placement agent fees and estimated offering expenses payable by us, and excluding the proceeds, if any, from the exercise of the Series A warrants issued in this offering, our pro forma as adjusted net tangible book value as of December 31, 2022 would have been approximately $(18.7), or approximately $(3.08) per share. This represents an immediate increase in net tangible book value to existing shareholders of $5.44 per share and an immediate dilution in net tangible book value of $4.23 per share of our common stock to the investors purchasing securities in this offering.

The following table illustrates this per share dilution to the new investors purchasing shares of common stock in this offering:

Assumed combined public offering price per share of common stock and accompanying Series A warrants (or Series D pre-funded warrants, assuming all such Series D pre-funded warrants are exercised)				$	1.15
Historical net tangible book value (deficit) per share as of December 31, 2022	$	(16.24	)
Pro forma increase in net tangible book value per share attributable to the Warrant Exercise	$	7.72
Pro forma net tangible book value per share December 31, 2022	$	(8.52	)
Increase in pro forma net tangible book value per share attributable to investors purchasing in this offering	$	5.44
As adjusted net tangible book value per share as of December 31, 2022 after this offering				$	(3.08	)
Dilution per share to investors purchasing in this offering				$	4.23

The foregoing table and calculations are based on 1,623,913 shares of our common stock outstanding as of December 31, 2022, and excludes:

• 1,939 shares of our common stock issuable upon the exercise of stock options outstanding, at a weighted-average exercise price of $3,525.88 per share;

• 10,611 shares of our common stock issuable upon the vesting and settlement of restricted stock units outstanding;

• 27,997 shares of our common stock available for future issuance under our 2019 Equity Incentive Plan; and

• 1,887,772 shares of our common stock issuable upon the exercise of warrants outstanding as of December 31, 2022 with a weighted-average exercise price of $13.25 per share.

DIRECTOR COMPENSATION

We have designed and implemented our compensation program for our non-employee directors to attract, motivate and retain individuals who are committed to our values and goals and who have the expertise and experience that we need to achieve those goals.

COMPENSATION PROGRAM

The table below depicts our compensation program for our non-employee directors:

COMPENSATION ELEMENTS — NON-EMPLOYEE DIRECTOR COMPENSATION PROGRAM
Cash
Annual Cash Retainer	$40,000
Annual Committee Chair Retainer
Audit	$20,000
Compensation	$15,000
Nominating and Corporate Governance	$9,000
Committee Member Retainer
Audit	$10,000
Compensation	$7,500
Nominating and Corporate Governance	$5,000
Annual Non-Executive Chairman of the Board Cash Retainer	$30,000

Initial Equity Grant	14 restricted stock units, vesting 50% on the first anniversary of the date of grant and 50% on the second anniversary of the date of grant.
Annual Equity Retainer	Restricted stock units in the amount of $70,000 and stock options in the amount of $65,000, each vesting on the first anniversary of the date of grant.

The cash fees described above are paid on a quarterly basis. Our non-employee directors are also reimbursed for their business-related expenses incurred in connection with attendance at Board and Committee meetings and related activities. In 2022, we suspended our annual equity retainer because we were limited in what we could issue under our 2019 Equity Incentive Plan, and instead granted each of our independent directors 986 cash-settleable restricted stock units.

EXECUTIVE OFFICER COMPENSATION

In 2022, our named executive officers were Gerri Henwood, our President and CEO, Jillian Dilmore, our Corporate Controller, Principal Financial Officer and Principal Accounting Officer, and Richard Casten, our former Chief Financial Officer, who departed the Company on April 16, 2022, as part of our reduction in force in an effort to reduce expenses.

This section discusses the material components of the executive compensation program for our named executive officers.

2022 SUMMARY COMPENSATION TABLE

The amounts reported in this column reflect the accounting cost for the restricted stock units and stock options and does not correspond to the actual economic value that may be received upon settlement of the restricted stock units or exercise of the stock option or any sale of any of the underlying shares of common stock.

(2) These amounts consist of 401(k) matching contributions.

(3) Ms. Dilmore was designated as our principal financial officer and principal accounting officer, effective April 16, 2022.

(4) Mr. Casten commenced employment with us on March 8, 2021 and departed the Company on April 16, 2022 as part of our reduction in force in an effort to reduce expenses.

(5) For Mr. Casten, this amount also includes severance and vacation time accrued for in 2022 upon his departure from the Company as required per his employment agreement, of which $390,000 was attributable to salary, $12,750 was attributable to unused and accrued vacation compensation and $45,309 was attributable to 401(k) matching contributions and the cost of subsidized medical benefits and life and disability insurance premiums.

(6) This amount represents the cash signing bonus awarded to Mr. Casten upon his commenced employment with the Company.

NARRATIVE TO SUMMARY COMPENSATION TABLE

Base salary

We use base salaries to recognize the experience, skills, knowledge and responsibilities required of all our employees, including our named executive officers. Base salaries are reviewed annually, typically in connection

20

with our annual performance review process, and adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. For the fiscal year ended December 31, 2022, the annual base salaries for Ms. Henwood, Ms. Dilmore and Mr. Casten were $618,000, $213,720 (which was increased to $235,092 effective March 14, 2022), and $390,000, respectively.

Equity Compensation

In 2022, we awarded equity compensation under our 2019 equity incentive plan to our named executive officers in the form of cash-settleable restricted stock units. We determine equity award amounts based on the judgment of our Compensation Committee, taking into account information and recommendations provided by our compensation consultant. With respect to our named executive officers other than our CEO, the Compensation Committee also considers recommendations provided by our CEO. In determining the amount of awards, the Compensation Committee generally does not consider an employee’s current equity ownership in our common stock or the prior awards that are fully vested, but may consider competitive market factors in our industry.

Our restricted stock unit awards typically vest in equal annual installments over a two- or four-year period subject to the continued service of the employee with us. We believe these vesting arrangements encourage our named executive officers to continue service with us for a longer period of time and remain focused on our multi-year long-term drug development and commercialization programs.

Non-Equity Incentive Plan Compensation

Each of our named executive officers are eligible to receive an annual performance bonus based on the achievement of pre-established corporate and/or individual objectives as determined by our Board and our Compensation Committee, in consultation with Pay Governance and upon review of the recommendations of our CEO for our other named executive officers. The Compensation Committee and the Board retained the discretion to make adjustments to the calculated bonus amount based on unexpected or unplanned events, the overall financial condition of the Company, extraordinary performance or underperformance or other factors deemed appropriate by the Compensation Committee and the Board. Each officer is assigned a target bonus expressed as a percentage of his or her base salary. Actual bonus payments may be higher or lower than the target bonus amount, as determined by our Board or Compensation Committee, based on the achievement of corporate and individual objectives. The target bonus amounts in 2022 for Ms. Henwood, Ms. Dilmore, and Mr. Casten were 60%, 25% and 37.5% of their respective base salaries. Mr. Casten was not entitled to a bonus for the 2022 fiscal year following his resignation.

In determining the amount of performance bonus awards, our Compensation Committee determines the level of achievement of the corporate goals and individual goals in respect of our non-CEO executive officers and our Board determines the amount of performance bonus awards for our CEO. In determining the level of achievement for our other named executive officers, our Compensation Committee reviews and considers the recommendations of our CEO. These achievement levels are used to determine each named executive officer’s bonus.

For 2022, the Compensation Committee and the Board determined that each named executive officer’s performance bonus should be based principally on contribution towards the achievement of corporate goals. These goals primarily included achievement of sales targets for ANJESO, raising capital to fund continued operations and managing cash to budget, out-licensing ANJESO or other pipeline candidates and completing pipeline development goals. The Compensation Committee and the Board determined that the percentage attainment of our corporate goals for 2022 was based primarily on achievement of revenue target for ANJESO, which was not achieved, and although other portions of the corporate goals for 2022 were achieved, in light of the company’s cash position, payment of performance bonuses would not be in the best interests of the Company or our shareholders. As such, our named executive officers did not receive cash bonuses for the year ended December 31, 2022.

21

QUALIFIED AND NON-QUALIFIED PLANS

We maintain a tax-qualified savings plan under Section 401(k) of the Internal Revenue Code. Employees who participate in the plan may make elective deferrals to the plan, subject to the limitations imposed by the Internal Revenue Code. In addition, we match 100% of employee deferrals under the plan, up to a limit of 5% of the employee’s eligible compensation (the eligibility compensation limit is established by the IRS annually and was $305,000 for 2022). None of our named executive officers are covered by a non-qualified deferred compensation plan

EMPLOYMENT AGREEMENTS

We traditionally had employment agreements with each of our named executive officers.

Compensation

The employment agreements provide for annual base salaries for each of our named executive officers, subject to adjustment from time to time. In addition, the employment agreements provide that each of our named executive officers is eligible to participate in our Company’s incentive bonus program. The base salaries and target bonus opportunities that were in effect for 2022 are described in the “Base Salaries” and “Annual Bonuses” sections above.

Restrictive Covenants

Under the employment agreements, the named executive officers are bound by a non-solicitation of employees and customers and a non-compete during their employment and the one-year period thereafter.

Termination and Severance

Pursuant to each of the employment agreements, if we terminate one of our named executive officer’s employment without cause (as defined below) or such named executive officer resigns for certain reasons

23

described below within 12 months of a change of control (as defined below), such named executive officer will generally be entitled to receive:

(i) any accrued but unused vacation and paid time off and any earned but unpaid bonus in respect of the prior year, or the Accrued Benefits;

(ii) continuation of such named executive officer’s base salary and health insurance benefits (including for eligible dependents), at active employee rates, for a period of 12 months following the date of termination, with respect to Mr. Casten, and for a period of 18 months following the date of termination, with respect to Ms. Henwood;

(iii) a pro-rata annual bonus in respect of the fiscal year in which the effective date of termination occurs, to the extent such bonus is earned based on the applicable criteria, paid at the same time it would have otherwise been paid absent the named executive officer’s termination of employment; and

(iv) outplacement services for a period of 12 months following the date of termination, which shall not exceed $25,000.

In connection with Mr. Casten’s termination in 2022, he was entitled to the above benefits pursuant to the terms of his employment agreement.

If Ms. Henwood’s employment is terminated as a result of her disability or death, she or her estate will be entitled to receive:

(i) the Accrued Benefits;

(ii) continuation of Ms. Henwood’s base salary and health insurance benefits (including for eligible dependents) at active employee rates for a period of 12 months following the date of termination;

(iii) a pro-rata target bonus in respect of the fiscal year in which the effective date of termination occurs, paid within 30 days of termination.

The severance benefits described above are generally subject to the named executive officer’s execution of a release of claims in favor of the Company and our affiliates. If the severance and other benefits provided in a named executive officer’s employment agreement or otherwise payable to a named executive officer would be subject to excise tax under Section 280(G) of the Code, then the named executive officer’s severance benefits will be either delivered in full or delivered as to such lesser extent that would result in no portion of the severance benefits being subject to such excise tax, whichever results in the receipt by the named executive officer, on an after-tax basis, of the greatest portion of such total severance and other benefits.

Cause

For purposes of the employment agreements, “cause” generally means a named executive officer’s (1) commission of an act of fraud or dishonesty against us; (2) willful failure to substantially perform his or her duties or material violation of the employment agreement, which failure or violation continues for 30 days or more following written notice to such named executive officer; (3) loss of any permit, license, accreditation or other authorization necessary for such named executive officer to perform his or her duties; (4) conviction of a felony or a plea of “no contest” to a felony; or (5) conduct that is likely, in the judgment of our Board, to materially adversely affect our reputation that continues for 5 days or more following written notice by us of such conduct.

Change of Control

For purposes of the employment agreements, a “change of control” shall generally be deemed to have occurred upon the happening of any of the following events: (1) the consummation by us of a plan of dissolution or

24

liquidation; (2) the consummation of the sale or disposition of all or substantially all of our assets; (3) the consummation by us of a merger, consolidation or other shareholder-approved fundamental business transaction in which we are a participant with another entity where our shareholders, immediately prior to the referenced transaction, will not beneficially own, immediately after the referenced transaction, shares or other equity interests entitling such shareholders to more than 50% of all votes to which all equity holders of the surviving entity would be entitled in the election of directors; (4) a third party shall have become the beneficial owner of, or shall have obtained voting control over, more than fifty percent (50%) of our outstanding shares of the common stock; or (5) a majority of the Board shall have been members of the Board for less than twenty-four (24) months.

A named executive officer will receive the payments and benefits described above if he or she resigns within 12 months of a change of control, because we and/or our successor: (1) materially and adversely change such named executive officer’s status, responsibilities or perquisites; (2) reduce such named executive officer’s base salary, except as part of an across the board decrease in which such executive officer’s percentage reduction is not more than any other executive officer, or reduce such named executive officer’s target bonus opportunity; or (3) require such officer to be principally based at any office or location more than 50 miles from such named executive officer’s principal office prior to the change of control, subject to a 30 day cure period, in each case, if we fail to cure these circumstances within 30 days after receiving notice from the named executive officer of his or her basis to resign.

POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS

Our Board has adopted a written related party transaction policy that governs the review and approval of related party transactions. This policy covers any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant, where the amount involved exceeds $120,000 and a related person had or will have a direct or indirect material interest. Pursuant to this policy, if we want to enter into a transaction with a related party or an affiliate of a related party, the Audit Committee will review the proposed transaction to determine, based on applicable rules of Nasdaq and the SEC, whether such transaction requires pre-approval by the Audit Committee. If pre-approval is required, the proposed transaction will be reviewed at the next regular or special meeting of the Audit Committee, and we may not enter into a related party transaction unless the Audit Committee has specifically confirmed in writing that either no further reviews are necessary or that all requisite corporate reviews have been obtained. In reviewing and approving any such transactions, our Audit Committee is tasked to consider all relevant facts and circumstances with respect to the transaction and shall evaluate all available options, including ratification, revision or termination of the transaction. All of the transactions described under “Certain Relationships and Related Party Transactions” in this Registration Statement either were approved or ratified in compliance with this policy.

Except as otherwise noted, each of the persons or entities in this table has sole voting and investing power with respect to all of the shares of common stock beneficially owned by them, subject to community property laws, where applicable.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is not complete and may not contain all the information you should consider before investing in our capital stock. This description is summarized from, and qualified in its entirety by reference to, our amended and restated certificate of incorporation, which has been publicly filed with the SEC. For more information on how you can obtain copies of our amended and restated certificate of incorporation and amended and restated bylaws, see “Where You Can Find More Information.”

Pursuant to our Amended and Restated Articles of Incorporation, our authorized capital stock consists of 190,000,000 shares of common stock, par value of $0.01 per share, and 10,000,000 shares of preferred stock, par value $0.01 per share, to be designated from time to time by our board of directors.

As of April 15, 2023, there were 2,585,702 shares of our common stock issued and outstanding and no shares of our preferred stock issued and outstanding.

Common Stock

Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of shareholders, including the election of directors, and do not have cumulative voting rights. Directors are elected by a plurality of the votes cast.

Subject to preferences that may be applicable to any then-outstanding shares of preferred stock, holders of our common stock are entitled to receive ratably dividends when, as, and if declared by our board of directors out of funds legally available therefor, subject to any preferential dividend rights of outstanding preferred stock. In the event of our liquidation, dissolution, or winding up, holders of our common stock will be entitled to ratably receive the net assets of our company available after the payments of all debts and other liabilities and subject to the prior rights of the holders of any then-outstanding shares of preferred stock.

Holders of our common stock have no preemptive, subscription, redemption or conversion rights. The rights and privileges of the holders of the common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

Our board of directors has the authority, without further action by our shareholders, to issue up to 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the dividend, voting and other rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon, and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in our control and may adversely affect the market price of the common stock and the voting and other rights of the holders of our common stock. We have no current plans to issue any shares of preferred stock.

Anti-Takeover Effects of Our Amended and Restated Articles of Incorporation and Our Amended and Restated Bylaws

Provisions of our Amended and Restated Articles of Incorporation and Amended and Restated Bylaws may delay or discourage transactions involving an actual or potential change of control or change in our management, including transactions in which shareholders might otherwise receive a premium for their shares, or transactions

31

that our shareholders might otherwise deem to be in their best interests. Therefore, these provisions could adversely affect the price of our common stock. Among other things, our Amended and Restated Articles of Incorporation and Amended and Restated Bylaws:

• divide our board of directors into three classes with staggered three-year terms;

• provide that a special meeting of shareholders may be called only by a majority of our board of directors, the chairman of our board of directors, the chief executive officer or the president;

• establish advance notice procedures with respect to shareholder proposals to be brought before a shareholder meeting and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of director;

• provide that shareholders may only act at a duly organized meeting; and

• provide that members of our board of directors may be removed from office by our shareholders only for cause by the affirmative vote of 75% of the total voting power of all shares entitled to vote generally in the election of directors.

Our Amended and Restated Articles of Incorporation also provide that, unless we consent in writing to the selection of an alternative forum, a state or federal court located within the County of Philadelphia in the Commonwealth of Pennsylvania will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of our company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of the Pennsylvania Business Corporation Law, or PBCL, or (iv) any action asserting a claim peculiar to the relationships among or between our company and our officers, directors and shareholders.

The exclusive forum provision described above is intended to apply to the fullest extent permitted by law, including to actions arising under the Securities Act or the Securities Exchange Act of 1934, or the Exchange Act. However, the enforceability of exclusive forum provisions in the governing documents of other companies has been challenged in legal proceedings, and it is possible that a court could find our forum selection provision to be inapplicable or unenforceable with respect to actions arising under the Securities Act or the Exchange Act. Even if it is accepted that our exclusive forum provision applies to actions arising under the Securities Act, shareholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder.

Anti-Takeover Provisions under Pennsylvania Law

Provisions of the PBCL applicable to us provide, among other things, that:

• we may not engage in a business combination with an “interested shareholder,” generally defined as a holder of 20% of a corporation’s voting stock, during the five-year period after the interested shareholder became such except under certain specified circumstances;

• holders of our common stock may object to a “control transaction” involving us (a control transaction is defined as the acquisition by a person or group of persons acting in concert of at least 20% of the outstanding voting stock of a corporation), and demand that they be paid a cash payment for the “fair value” of their shares from the “controlling person or group”;

• holders of “control shares” will not be entitled to voting rights with respect to any shares in excess of specified thresholds, including 20% voting control, until the voting rights associated with such shares are restored by the affirmative vote of a majority of disinterested shares and the outstanding voting shares of the Company; and

• any “profit,” as defined, realized by any person or group who is or was a “controlling person or group” with respect to us from the disposition of any equity securities of within 18 months after the person or group became a “controlling person or group” shall belong to and be recoverable by us.

Pennsylvania-chartered corporations may exempt themselves from these and other anti-takeover provisions. Our Amended and Restated Articles of Incorporation do not provide for exemption from the applicability of these or other anti-takeover provisions in the PBCL.

The provisions noted above may have the effect of discouraging a future takeover attempt that is not approved by our board of directors but which individual shareholders may consider to be in their best interests or in which shareholders may receive a substantial premium for their shares over the then current market price. As a result, shareholders who might wish to participate in such a transaction may not have an opportunity to do so. The provisions may make the removal of our board of directors or management more difficult. Furthermore, such provisions could result in our company being deemed less attractive to a potential acquiror and/or could result in our shareholders receiving a lesser amount of consideration for their shares of our common stock than otherwise could have been available either in the market generally and/or in a takeover.

DESCRIPTION OF SECURITIES WE ARE OFFERING

We are offering 1,326,175 shares of common stock, together with Series A-5 warrants to purchase 1,326,175 shares of common stock (the “Series A-5 warrants”) and Series A-6 warrants to purchase 1,326,175 shares of common stock (the “Series A-6 warrants,” and together with the Series A-5 warrants, the “Series A warrants”). We are also offering 2,152,087 Series D pre-funded warrants, together with Series A-5 warrants to purchase 2,152,087 shares of common stock and Series A-6 warrants to purchase 2,152,087 shares of common stock (collectively with the Series A warrants, the “warrants”) to those purchasers, whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock following the consummation of this offering in lieu of the shares of our common stock that would result in ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%). Each Series D pre-funded warrant will be exercisable for one share of common stock. Each Series D pre-funded warrant is being issued together with the same Series A warrant described above being issued with each share common stock. The shares of common stock or Series D pre-funded warrants, as the case may be, and the Series A warrants, can only be purchased together in this offering, but the shares of common stock and Series D pre-funded warrants and Series A warrants are immediately separable and will be issued separately in this offering. We are also registering the shares of common stock and the shares of common stock issuable from time to time upon exercise of the Series D pre-funded warrants and Series A warrants offered hereby.

Common Stock

The description of our common stock under the section “Description of Our Capital Stock” in this prospectus is incorporated herein by reference.

Series A-5 Warrants

The following summary of certain terms and provisions of the Series A-5 warrants included with the shares of common stock and the Series D pre-funded warrants that are being issued hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Series A-5 warrants, the form of which will be filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of Series A-5 warrant for a complete description of the terms and conditions of the Series A-5 warrants.

Duration and Exercise Price

Each Series A-5 warrant offered hereby will have an initial exercise price equal to $1.15 per share of common stock. The Series A-5 warrants will be immediately exercisable and will expire on May 1, 2028. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Series A-5 warrants will be issued separately from the common stock, or the Series D pre-funded warrants, as the case may be, in certificated form only.

Exercisability

The Series A-5 warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Series A-5 warrant to the extent that the holder would own more than 4.99% (or, at the election of the purchaser prior to the issuance of the Series A-5 warrants, 9.99%) of the outstanding common stock immediately after exercise. Following the issuance of the Series A-5 warrants, upon notice from the holder to us, the holder may increase or decrease the amount of beneficial ownership of

34

outstanding stock after exercising the holder’s Series A-5 warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Series A-5 warrants and in accordance with the rules and regulations of the Securities and Exchange Commission, or the SEC, provided that any increase in the beneficial ownership limitation shall not be effective until 61 days following notice to us.

Cashless Exercise

If, at the time a holder exercises its Series A-5 warrants, a registration statement registering the issuance of the shares of common stock underlying the Series A-5 warrants under the Securities Act is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the Series A-5 warrants.

Fractional Shares

No fractional shares of common stock will be issued upon the exercise of the Series A-5 warrants. Rather, the number of shares of common stock to be issued will be rounded up to the next whole share or we will pay a cash adjustment equal to such fraction multiplied by the exercise price to the holder.

Transferability

Subject to applicable laws, a Series A-5 warrant may be transferred at the option of the holder upon surrender of the Series A-5 warrant to us together with the appropriate instruments of transfer.

In addition, in the event of a fundamental transaction which is approved by our board of directors, the holders of the Series A-5 warrants have the right to require us or a successor entity to redeem the Series A-5 warrant for cash in the amount of the Black-Scholes value of the

The placement agent is not purchasing or selling any securities, nor are they required to arrange for the purchase and sale of any specific number or dollar amount of securities, other than to use their “reasonable best efforts” to arrange for the sale of the securities by us. Therefore, we may not sell the entire amount of securities being offered. There is no minimum amount of proceeds that is a condition to closing of this offering. The placement agent does not guarantee that it will be able to raise new capital in this offering. We will enter into a securities purchase agreement directly with investors in connection with this offering. The placement agent may engage one or more sub-placement agents or selected dealers to assist with the offering. The placement agent is not required to sell any specific number or dollar amount of securities but will use their best efforts to sell the securities offered. This offering will terminate on May 10, 2023, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share (or pre-funded warrant) and warrants will be fixed for the duration of this offering.

Lock-up Agreements

We and each of our officers and directors have agreed with the Placement Agent to be subject to a lock-up period of 60 days following the date of closing of the offering pursuant to this prospectus.
