The 2019 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based awards. The Company’s employees, officers, directors, consultants and advisors are eligible to receive awards under the 2019 Plan. The 2019 Plan is administered by the Company’s board of directors. As of December 31, 2020 awards may be made under the 2019 Plan for up to such number of shares of the Company’s common stock as is equal to the sum of: i) 1,578,947 shares; plus ii) the number of shares (up to 1,157,894 shares) equal to the number of shares of the Company’s common stock subject to outstanding awards under the 2012 Stock Incentive Plan (the “2012 Plan”) that expire, terminate or are otherwise cancelled, forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right; plus iii) an annual increase to be added on the first day of each fiscal year, beginning with 2020 and continuing through 2029, equal to the least of (a) 2,105,623 shares of common stock, (b) 4% of the number of outstanding shares of the Company’s common stock on such date, and (c) an amount determined by the Company’s board of directors. The number of shares reserved for issuance under the 2019 Plan increased, pursuant to the terms of the 2019 Plan, by an additional 713,383 shares, equal to 4% of the Company’s then-outstanding common stock, effective as of January 1, 2020. The 2012 Plan was adopted by the Company’s board of directors and stockholders. The Company’s board of directors administers the 2012 Plan. The 2012 Plan provides for the issuance of stock-based awards to the Company’s employees, officers and directors, as well as non-employee/consultants and advisors to the Company. Options granted under the 2019 Plan and the 2012 Plan have a maximum term of ten years. Options granted to employees, officers and non-employee consultants vest over four years based on varying vesting schedules including: 25% vesting on the first anniversary date of grant and the balance ratably over the next 36 months or vesting in equal monthly or quarterly installments over four years. Options granted to directors generally vest over up to one to two years. As of December 31, 2020 and 2019, respectively, options to purchase 1,249,653 and 631,234 shares of common stock were granted and outstanding, net of cancelations, under the 2019 Plan. As of December 31, 2020 and 2019, respectively, options to purchase 921,824 and 1,043,992 shares of common stock were granted and outstanding, net of cancelations, under the 2012 Plan. In April 2019, the Company’s board of directors adopted a resolution effective on May 7, 2019 that no further stock options or other equity-based awards may be granted under the 2012 Plan. A summary of the Company’s combined stock option activity for the 2019 Plan and the 2012 Plan for the year ended December 31, 2020 is as follows: Number of Option Shares Weighted Average Exercise Price Weighted Average Contractual Term Aggregate Intrinsic Value (in years) (in thousands) Outstanding as of December 31, 2019 1,675,226 $ 6.20 7.8 $ 864 Granted 764,583 5.11 Forfeited (163,463 ) 7.77 Expired (86,526 ) 9.18 Exercised (18,343 ) 1.82 Outstanding as of December 31, 2020 2,171,477 $ 5.62 7.5 $ 185 Options exercisable as of December 31, 2020 1,009,847 $ 4.67 6.0 $ 185 Options unvested as of December 31, 2020 1,161,630 $ 6.44 8.8 $ — The weighted average grant-date fair value per share of stock options granted was $3.68 and $5.06 for the years ended December 31, 2020 and 2019, respectively. The aggregate fair value of stock options that vested during the years ended December 31, 2020 and 2019 was $2.2 million and $688, respectively. The aggregate intrinsic value of stock options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair value of the Company’s common stock. The aggregate intrinsic value of stock options exercised during the years ended December 31, 2020 and 2019 was $81 and $105, respectively. The assumptions that the Company used to determine the fair value of the stock options granted were as follows, presented on a weighted average basis: Year Ended December 31, 2020 2019 Risk-free interest rate 1.2 % 2.0 % Expected volatility 81.5 % 78.7 % Expected dividend yield — — Expected life of options (in years) 6.8 6.8 In April 2019, the Company’s board of directors adopted the 2019 Employee Stock Purchase Plan (the “2019 ESPP”), which became effective on May 7, 2019. The 2019 ESPP is administered by the Company’s board of directors. The Company recognized $5 of stock-based compensation expense for the 2019 ESPP during the year ended December 31, 2020. During the year ended December 31, 2019, there was no activity under the 2019 ESPP. The number of shares of the Company’s common stock that have been approved to be issued under the 2019 ESPP is equal to the sum of: i) 155,106 shares; plus ii) an annual increase to be added on the first day of each fiscal year, beginning with the fiscal year ending December 31, 2020 and continuing for each fiscal year until, and including, the fiscal year ending December 31, 2029, equal to the least of (a) 526,315 shares of common stock, (b) 1% of the number of outstanding shares of the Company’s common stock on such date, and (c) an amount determined by the Company’s board of directors. The aggregate number of shares of the Company’s common stock that may be issued under the 2019 ESPP increased, pursuant to the terms of the 2019 ESPP, by an additional 178,345 shares, equal to 1% of the Company’s then-outstanding common stock, effective as of January 1, 2020. All of the Company’s employees are eligible to participate in the 2019 ESPP, provided that: • such person is customarily employed by the Company for more than 20 hours a week and for more than five months in a calendar year; • such person has been employed by the Company for at least three months prior to enrolling in the 2019 ESPP; and • such person was an employee of the Company on the first day of the applicable offering period under the 2019 ESPP. The following table summarizes the classifications of stock-based compensation expenses for the 2012 Plan, the 2019 Plan and the 2019 ESPP recognized in the Consolidated Statements of Operations: Year Ended December 31, 2020 2019 Research and development expense $ 360 $ 143 General and administrative expense 2,057 984 $ 2,417 $ 1,127 As of December 31, 2020, total unrecognized compensation cost related to the unvested share-based awards was $4.4 million, which is expected to be recognized over a weighted average period of 2.5 years. Redeemable Convertible Preferred Stock Upon the closing of the IPO, the Company’s outstanding redeemable convertible preferred stock, including the accrued dividends thereon, automatically converted into an aggregate of 10,381,234 shares of the Company’s common stock. Upon such conversion of the redeemable convertible preferred stock, the Company reclassified the carrying values of the redeemable convertible preferred stock to common stock and additional paid-in capital. Prior to the conversion into common stock as noted above, the Company’s redeemable convertible preferred stock was redeemable on or after July 14, 2020 and carried a cumulative coupon dividend rate of 6%. The redemption amount per share for a share of redeemable convertible preferred stock was the greater of (A) the applicable original issue price per share for such series of redeemable convertible preferred stock, plus any of the dividends accrued but unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon, and (B) the fair market value per share of redeemable convertible preferred stock, as described below under Redemption Rights. The Company accounted for its redeemable convertible preferred stock under the requirements of ASC 480, which establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. The carrying value of the redeemable convertible preferred stock was presented as temporary equity and was adjusted by periodic accretions so that the carrying amount equaled the redemption amount at the estimated date that the redeemable convertible preferred stock would be redeemed. These adjustments were effected through charges against additional paid-in capital, to the extent it was available, or accumulated deficit. For all issuances of redeemable convertible preferred stock, the difference between the amount invested by the holders of the redeemable convertible preferred stock, net of issuance costs and premiums (or discounts), as compared to the redemption value, was recorded as accretion over the redemption period of the redeemable convertible preferred stock. The accretion was added to net loss to arrive at the net loss available to common stockholders in the calculation of net loss per common share. Issuance of Series A Redeemable Convertible Preferred Stock On December 4, 2012, the Company entered into the Series A Preferred Stock Purchase Agreement (the “Series A Purchase Agreement”) with TPG Biotechnology Partners III, L.P. (“TPG”) and nine other holders of the Company’s convertible notes that were issued in 2011 and 2012 (the “Series A Investors”). Pursuant to the Series A Purchase Agreement, the Company issued 6,000,000 shares (the “Series A Initial Closing”) of Series A Preferred Stock to TPG at a purchase price of $1.00 per share, resulting in proceeds, net of $128 in issuance costs, of $5.9 million (the “Series A Financing”). Concurrently, convertible notes held by the Series A Investors totaling $564, including accrued interest, were automatically converted at a conversion price of $0.467 per share in accordance with calculations specified in the applicable note purchase agreement, and the Company issued 1,207,923 shares of Series A Preferred Stock in settlement of the convertible notes. The Series A Purchase Agreement also provided for the sale of 4,000,000 additional shares of Series A Preferred Stock (the “Series A Milestone Shares”) to TPG at a purchase price of $1.00 per share upon the Company’s achievement of specified Milestone Events, as defined in the Series A Purchase Agreement, involving the Company’s Phase 1b clinical trial in uremic pruritus and a pending patent application. In the event the Milestone Events were not achieved, TPG had the right to purchase the Series A Milestone Shares, in full or in part, under the same terms and conditions as the Series A Initial Closing, including the $1.00 per share purchase price, on or before June 30, 2014. In addition, TPG had the right to purchase, under the same terms and conditions as the Series A Initial Closing, including the $1.00 per share purchase price, the lesser of 2,500,000 additional shares of Series A Preferred Stock (the “Additional Series A Preferred Shares”) and the number of shares of Series A Preferred Stock equal to 25% of the total number of shares of Series A Preferred Stock it previously purchased for cash under the Series A Purchase Agreement. This additional right was exercisable until the date six months after the completion date of the Company’s Phase 2b/3 clinical trial of Haduvio in patients with uremic pruritus. On December 26, 2013, TPG purchased under a Series A Extension Preferred Stock Purchase Agreement (the “Series A Extension Purchase Agreement”) 6,500,000 additional shares of Series A Preferred Stock at $1.00 per share, which consisted of the Series A Milestone Shares and the Additional Series A Preferred Shares discussed above, resulting in proceeds, net of $39 in issuance costs, of $6.5 million. This agreement also provided that the Company could sell up to 2,000,000 additional shares at $1.00 per share to existing stockholders deemed accredited investors within 45 days of the December 26, 2013 closing. In January 2014, the Company issued 1,680,000 shares of Series A Preferred Stock to eight of the Series A Investors at $1.00 per share, as provided for as Additional Closings under the Series A Extension Purchase Agreement, resulting in proceeds, net of $7 in issuance costs, of $1.7 million. The Company recorded this issuance at its fair value of $1.08 per share, totaling $1.8 million before financing costs, resulting in a discount on this issuance in the amount of $134, which amount was being amortized out of the carrying value of Series A Preferred Stock over the expected redemption period, which was three years from July 14, 2017, the date of the First Tranche Closing of the Series C Preferred Stock Financing (each such term as defined below), or July 14, 2020 (the “Redemption Period”). Such amortization totaled $7 for the year ended December 31, 2019 which includes $5 of previously unaccreted discount on issuance at the time of conversion to shares of common stock. There was no such amortization for the year ended December 31, 2020. Holders of Series C Preferred Stock had a higher liquidation preference than the holders of Series A Preferred Stock and Series B Preferred Stock. (See Liquidation Preferences note below.) Issuance of Series B Redeemable Convertible Preferred Stock On May 23, 2014, the Company entered into the Series B Preferred Stock Purchase Agreement (the “Series B Purchase Agreement”) with TPG. Pursuant to the Series B Purchase Agreement, the Company issued 13,043,478 shares (the “Series B Initial Closing”) of Series B Preferred Stock to TPG at a purchase price of $1.15 per share, resulting in proceeds, net of $56 in issuance costs, of $15.0 million. The Series B Purchase Agreement also provided for the sale of 4,347,826 additional shares of Series B Preferred Stock (the “Series B Milestone Shares”) to TPG at a purchase price of $1.15 per share upon the Company’s achievement of specified Milestone Events, as defined in the Series B Purchase Agreement, involving the Company’s Phase 2b/3 clinical trial of Haduvio in patients with uremic pruritus; its planned Phase 2 clinical trial of Haduvio in patients with pruritus associated with prurigo nodularis; and a pending patent application. In the event the Milestone Events were not achieved, TPG had the right to purchase the Series B Milestone Shares, in full or in part, under the same terms and conditions as the Series B Initial Closing, at a purchase price of $1.15 per share, on or before November 30, 2015. In addition, TPG had the right to purchase, on the same terms and conditions as the Series B Initial Closing, including the $1.15 per share purchase price, the lesser of 4,347,826 additional shares of Series B Preferred Stock and the number of shares equal to 25% of the total number of shares it previously purchased for cash under the Series B Purchase Agreement (the “Additional Series B Shares”). This additional right was exercisable until the date six months after the completion date of the Company’s Phase 2b/3 clinical trial of Haduvio in patients with uremic pruritus. On October 30, 2014, TPG exercised its rights described above and purchased under an Additional Closing Agreement (the “Series B Second Closing”) 8,695,652 additional shares of Series B Preferred Stock at $1.15 per share, which consisted of the Series B Milestone Shares and the Additional Series B Shares. This agreement also provided for the Company to sell 869,565 additional shares of Series B Preferred Stock at $1.15 per share to an existing stockholder. The Series B Second Closing resulted in proceeds, net of $19 in issuance costs, of $11.0 million. The Company recorded this issuance at its fair value of $1.10 per share, totaling $10.5 million, net of financing costs, resulting in a premium on this issuance in the amount of $478 which amount was being accreted into the carrying value of the Series B Preferred Stock over the Redemption Period. Such accretion totaled $31 for the year ended December 31, 2019 which includes $22 of unaccreted premium on issuance at the time of conversion to shares of common stock. There was no such accretion for the year ended December 31, 2020. Holders of Series C Preferred Stock had a higher liquidation preference than the holders of Series A Preferred Stock and Series B Preferred Stock. (See Liquidation Preferences note below.) Issuance of Series C Redeemable Convertible Preferred Stock On July 14, 2017, the Company entered into the Series C Purchase Agreement with TPG and other institutional investors (the “Series C Initial Purchasers”) for the issuance of $50.5 million of its Series C Preferred Stock. The Series C Purchase Agreement provided for the Company’s Series C Preferred Stock to be issued in two tranches, with the closing of the first tranche on July 14, 2017 (the “First Tranche Closing”) and the closing of the second tranche to occur following a determination by the Company’s board of directors that the Company’s cash and cash equivalents at such time are not sufficient to fund its operations for a period of three months following such determination (the “Second Tranche Closing”). Upon the First Tranche Closing, the Company issued 20,547,946 shares of its Series C Preferred Stock at a purchase price of $1.46 per share, resulting in proceeds of $29.7 million, net of issuance costs of $291. Also party to the Series C Purchase Agreement were eleven holders of the Company’s Convertible Notes (together with the Initial Purchasers and the Series C Additional Purchasers, as defined below, the “Series C Investors”). Concurrently with the First Tranche Closing and pursuant to the Series C Purchase Agreement, the outstanding principal on the Company’s Convertible Notes, totaling $10.6 million, and all accrued interest thereon, totaling $564, were automatically converted at the Mandatory Conversion Price of $1.095 per share, and the Company issued 10,181,233 shares of its Series C Preferred Stock in full settlement of the Convertible Notes. The Series C Purchase Agreement provided for a subsequent closing (the “Special Closing”), on the same terms and conditions as the First Tranche Closing, including the $1.46 per share purchase price, and on October 11, 2017, the Special Closing occurred, resulting in the issuance to two additional investors (the “Series C Additional Purchasers”) of 101,707 shares of the Company’s Series C Preferred Stock, at a purchase price of $1.46 per share, resulting in proceeds of $129, net of issuance costs of $19. On November 12, 2017, one of the Series C Additional Purchasers purchased its second tranche shares pursuant to an election under the Series C Purchase Agreement, resulting in the issuance of 55,621 shares of the Company’s Series C Preferred Stock at a purchase price of $1.46 per share, resulting in proceeds of $81. On August 28, 2018, the Company amended the Series C Purchase Agreement to provide that a portion of the shares of Series C Preferred Stock that would otherwise be issued and sold at the Second Tranche Closing would instead be issued and sold at a third tranche closing (the “Third Tranche Closing”), with such closing to occur following a determination by the Company’s board of directors that the Company’s cash and cash equivalents at such time are not sufficient to fund its operations for a period of three months following such determination. On August 30, 2018, the Company completed the Second Tranche Closing, resulting in the issuance of 7,211,165 shares of the Company’s Series C Preferred Stock, at a purchase price of $1.46 per share, resulting in proceeds of $10.5 million, net of issuance costs of $32. On January 18, 2019, the Company completed the Third Tranche Closing, resulting in the issuance of 6,849,315 shares of the Company’s Series C Preferred Stock, at a purchase price of $1.46 per share, resulting in proceeds of $10.0 million, net of issuance costs of $37. At such time, the Series C redeemable convertible preferred stock liability of $1.1 million was reclassified as Series C Preferred Stock. Series C Redeemable Convertible Preferred Stock Liability and Changes in Fair Value As discussed above, the Series C Purchase Agreement provided for the issuance and sale of Series C Preferred Stock in three separate tranches. The tranches represented a freestanding financial instrument under ASC 480 and required fair value accounting until they were settled. The Company recognized a liability on its Consolidated Balance Sheet for the obligations under this financial instrument. The Company adjusted this liability to fair value at each reporting date, as applicable, and recognized any changes in fair value of the Series C Preferred Stock in its Consolidated Statements of Operations as a component of other income (expense). The Company continued to recognize any changes in the fair value of this liability through the closing of the third tranche. Accordingly, for the year ended December 31, 2018, the Company recorded the Series C redeemable convertible preferred stock liability at its fair value of $2.1 million, with a corresponding charge to other income (expense) in the Company’s Consolidated Statement of Operations. Upon the Second Tranche Closing in August 2018, as described above, $1.0 million was reclassified to Series C Preferred Stock. As a result, at December 31, 2018, the fair value of this liability, relating to the outstanding third tranche, was determined to be $1.1 million and was reclassified to Series C Preferred Stock upon the Third Tranche Closing in January 2019. The fair value of the Series C redeemable convertible preferred stock liability was estimated as the excess, if any, of the fair value per share of the Company’s Series C Preferred Stock, as described below under Redemption Rights, over the purchase price of any outstanding tranches to be sold pursuant to the Series C Purchase Agreement. Holders of Series C Preferred Stock had a higher liquidation preference than the holders of Series A Preferred Stock and Series B Preferred Stock. (See Liquidation Preferences note below.) As of December 31, 2020 and 2019, there were no shares of redeemable convertible preferred stock outstanding as a result of the conversion into common stock in connection with the IPO. Dividends Dividends on outstanding shares of Series A, Series B and Series C Preferred Stock accrued at a rate of 6% per annum on their original purchase price of $1.00, $1.15 and $1.46 per share, respectively (the “Accruing Dividends”), whether or not declared, and were cumulative. However, Accruing Dividends on the Company’s outstanding redeemable convertible preferred stock were payable only when, as and if declared by the Company’s board of directors, or upon liquidation, redemption or conversion. No dividends were payable to the holders of the Company’s common stock unless equivalent dividends had been declared and paid on the Company’s outstanding Series A, Series B and Series C Preferred Stock. No dividends had been declared or paid by the Company through the date of the IPO. Accruing Dividends totaled $18.4 million through the date of the IPO, at which time they were converted into common shares. Liquidation Preferences In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company or deemed liquidation event, the holders of shares of Series C Preferred Stock then outstanding were entitled to be paid out of the assets of the Company that were available for distribution to its stockholders, before any payments were to be made to the holders of Series A Preferred Stock, Series B Preferred Stock or common stock by reason of their ownership thereof, an amount per share equal to the Series C Preferred Stock original issue price of $1.46 per share, plus any Accruing Dividends accrued but unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon. If upon any such liquidation, dissolution or winding up of the Company or deemed liquidation event, the assets of the Company available for distribution to its stockholders were insufficient to pay the holders of shares of Series C Preferred Stock the full amount to which they were entitled, the holders of Series C Preferred Stock were entitled to share ratably in any distribution of the assets available for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares of Series C Preferred Stock held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company or deemed liquidation event, the holders of shares of Series A Preferred Stock and Series B Preferred Stock then outstanding were entitled to be paid out of the assets of the Company available for distribution to its stockholders after the payment of all preferential amounts required to be paid to the holders of shares of Series C Preferred Stock but before any payments were made to the holders of common stock by reason of their ownership thereof, (i) an amount per share equal to the Series A original issue price of $1.00 per share in the case of the Series A Preferred Stock, plus any Accruing Dividends accrued but unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon, and (ii) an amount per share equal to the Series B original issue price of $1.15 per share in the case of the Series B Preferred Stock, plus any Accruing Dividends accrued but unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon. If upon any such liquidation, dissolution or winding up of the Company or deemed liquidation event, the assets of the Company available for distribution to its stockholders were insufficient to pay the holders of shares of Series A Preferred Stock and Series B Preferred Stock the full amount to which they were entitled (after the payment in full of all preferential amounts required to be paid to the holders of shares of Series C Preferred Stock), the holders of shares of Series A Preferred Stock and Series B Preferred Stock were entitled to share ratably in any distribution of the assets available for distribution in respect of such shares in proportion to the respective amounts which would otherwise be payable in respect of the share of Series A Preferred Stock and Series B Preferred Stock held by them upon such distribution if all amounts payable on or with respect to such shares were paid in full. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company or deemed liquidation event, after the payment of all preferential amounts required to be paid to the holders of shares of redeemable convertible preferred stock, the remaining assets of the Company available for distribution to its stockholders were to be distributed among the holders of the shares of redeemable convertible preferred stock and common stock, in proportion to the number of shares held by each such holder, treating for this purpose all such securities as if they had been converted into common stock pursuant to the terms of the Company’s certificate of incorporation immediately prior to such dissolution, liquidation or winding up of the Company. Redemption Rights The Company’s certificate of incorporation provided that, unless prohibited by Delaware law governing distributions to stockholders, shares of the redeemable convertible preferred stock were to be redeemed by the Company in three annual installments commencing not more than 60 days after receipt by the Company, at any time on or after July 14, 2020, of written notice from the holders of at least a majority of the outstanding shares of redeemable convertible preferred stock, voting together as a single class on an as-converted basis, requesting redemption of all shares of redeemable convertible preferred stock (a “Redemption Request”). In that event, unless prohibited by Delaware law governing distributions to stockholders, generally in connection with an insolvent corporation, shares of Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock, respectively, were to be redeemed by the Company at a price equal to the greater of (A) the applicable original issue price per share for such series of redeemable convertible preferred stock, plus any Accruing Dividends accrued but unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon, and (B) the fair market value per share of Series A Preferred Stock, Series B Preferred Stock or Series C Preferred Stock, as the case may be, as of the date of the Company’s receipt of the Redemption Request. For purposes of these redemption rights, the fair market value per share of the Series A Preferred Stock was defined as the value per share of Series A Preferred Stock as mutually agreed upon by the Company and the holders of 60% of the shares of Series A Preferred Stock then outstanding, and, in the event that they were unable to reach agreement, by a third-party appraiser agreed to by the Company and the holders of a majority of the shares of Series A Preferred Stock then outstanding; the fair market value per share of the Series B Preferred Stock was defined as the value per share of Series B Preferred Stock as mutually agreed upon by the Company and the holders of 60% of the shares of Series B Preferred Stock then outstanding, and, in the event that they were unable to reach agreement, by a third-party appraiser agreed to by the Company and the holders of a majority o |
