Overview We are a commercial-stage, cancer prevention, medical diagnostics technology company focused on the millions of patients with long-standing gastroesophageal reflux disease (“GERD”) who are at risk of developing esophageal precancer and cancer, specifically highly lethal esophageal adenocarcinoma (“EAC”), which is expected to lead to approximately 16,000 U.S. deaths per year. We believe that our lead products, the EsoGuard Esophageal DNA Test performed on samples collected with the EsoCheck Esophageal Cell Collection Device, constitutes the first and only commercially available diagnostic test capable of serving as a widespread screening tool to prevent EAC deaths, through early detection of esophageal precancer in at-risk GERD patients. ● EsoGuard is a DNA test performed on surface esophageal cells collected with EsoCheck in a brief noninvasive office procedure which has been shown to be over 90% sensitive and specific at detecting Barrett’s Esophagus (“BE”), a precancerous condition of the esophagus and all conditions along the BE-EAC spectrum. (Moinova, et al. Sci Transl Med. 2018 Jan 17;10(424): eaao5848). ● EsoCheck is a United States Food and Drug Administration FDA 510(k) and CE Mark cleared noninvasive swallowable balloon capsule catheter capable of sampling surface esophageal cells in a less than five-minute office procedure. We believe its proprietary Collect+Protect™ technology makes it the only noninvasive esophageal cell collection device capable of anatomically targeted and protected sampling to prevent dilution and contamination during device withdrawal. EsoGuard is commercialized in the U.S. as a laboratory developed test (“LDT”). It was previously performed by our unrelated third-party commercial clinical laboratory service partner ResearchDx Inc. (“RDx”), at their Clinical Laboratory Improvement Amendments (“CLIA”) certified commercial clinical laboratory, located in Irvine, CA. Beginning in March 2022, the EsoGuard LDT has been performed at our own CLIA-certified commercial clinical laboratory, located in Lake Forest, CA. RDx also manufactures our EsoGuard Specimen Kits. EsoCheck is commercialized in the U.S. as a 510(k) cleared esophageal cell collection device currently manufactured for us by our contract manufacturing partner, Sage Product Development Inc., located in Foxborough, MA. We are in the process of transferring EsoCheck manufacturing to Coastline International Inc., a high-volume manufacturer headquartered in San Diego, CA with plants in Mexico. Both EsoGuard and EsoCheck have completed the CE Mark certification process. EsoGuard, us ed with EsoCheck was granted FDA Breakthrough Device designation and requires the completion of an international multicenter pre-market approval (“PMA”) clinical trial to be able to submit EsoGuard to the FDA for approval as an in vitro diagnostic device (“IVD”). Presently, the Company is focusing its clinical trial efforts and resources towards supporting insurance reimbursement adoption by government and private insurers. Consequently, with the Company prioritizing shorter term clinical utility studies to facilitate widespread insurance adoption, the completion of the BE-1 EsoGuard screening (as described below) study will be delayed indefinitely. The Company expects to complete the EsoGuard BE-2 case control study (as described below) in due course. The EsoGuard PLA code 0114U secured final Medicare payment determination of $1,938.01, effective January 1, 2021. We are awaiting Medicare local coverage determination. We are also aggressively pursuing EsoGuard U.S. private payor payment and coverage as well as payment in Europe. We are working to expand EsoGuard commercialization across multiple channels by building a direct sales and marketing team targeting primary care physicians, specialists, institutions and consumers. To assure sufficient testing capacity and geographic coverage, as part of this expansion, we are building our own network of Lucid Test Centers, staffed by Lucid-employed clinical personnel, where patients can undergo the EsoCheck procedure and have the sample sent for EsoGuard testing. We have also established an EsoGuard Telemedicine Program, in partnership with UpScript, LLC, an independent third-party telemedicine provider, that can accommodate EsoGuard self-referrals from direct-to-consumer marketing. Overview In connection with our efforts to expand our presence in the diagnostic market, we are also developing EsoCure as an Esophageal Ablation Device, with the intent to allow a clinician to treat dysplastic BE before it can progress to EAC, a highly lethal esophageal cancer, and to do so without the need for complex and expensive capital equipment. As described below, we recently entered into a license agreement with our parent company, PAVmed Inc., pursuant to which we were granted the rights to commercialize EsoCure. A successful pre-clinical feasibility animal study of EsoCure has been completed, demonstrating excellent, controlled circumferential ablation of the esophageal mucosal lining. An acute and survival animal study of EsoCure™ Esophageal Ablation Device has also been completed, demonstrating successful direct thermal balloon catheter ablation of esophageal lining through the working channel of a standard endoscope. We plan to conduct additional development work and animal testing of EsoCure to support a future FDA 510(k) submission. We are a majority owned subsidiary of PAVmed. We are party to an amended and restated patent license agreement with CWRU, dated August 23, 2021 (“Amended CWRU License Agreement”), which provides for the exclusive worldwide license of the intellectual property rights for the proprietary technologies underlying EsoCheck and EsoGuard. Recent Developments Business Clinical Guideline Update - ACG and AGA In April 2022, the American College of Gastroenterology (“ACG”) updated its clinical guideline to support esophageal precancer (“Barrett’s Esophagus”- or “BE”) screening to prevent highly lethal EAC utilizing our EsoGuard® DNA Test on samples collected with our EsoCheck® Cell Collection Device. The clinical guideline reiterates the ACG’s long-standing recommendation for esophageal precancer screening in at-risk patients with GERD, commonly known as chronic heartburn, acid reflux or simply reflux. In its Recommendation 5, the ACG suggests a single screening endoscopy in patients with chronic GERD symptoms and 3 or more additional risk factors for BE, including male sex, age greater than 50 years, White race, tobacco smoking, obesity, and family history of BE or EAC in a first-degree relative. Furthermore, and importantly for the first time, the clinical guideline also endorses nonendoscopic biomarker screening as an acceptable alternative to costly and invasive endoscopy by stating in its Recommendation 6 that the ACG suggests that a swallowable, nonendoscopic capsule device combined with a biomarker is an acceptable alternative to endoscopy for screening for BE. The clinical guideline specifically mentions EsoCheck, along with the Company’s EsophaCap® device, as such swallowable, nonendoscopic esophageal cell collection devices, as well as methylated DNA biomarkers such as EsoGuard. The summary of evidence for this recommendation cites the seminal NIH-funded multicenter, case-control study published in 2018 in Science Translational Medicine, which demonstrated that EsoGuard is highly accurate at detecting esophageal precancer and cancer, including on samples collected with EsoCheck. In July 2022, the American Gastroenterology Association (“AGA”) published updated clinical guidance that mirrors the same furnished by the ACG as described above , without Recent Developments Business - continued Local Coverage Determination Update - CMS In April 2022, a proposed Local Coverage Determination (“LCD”) DL39256, entitled “Molecular Testing for Detection of Upper Gastrointestinal Metaplasia, Dysplasia, and Neoplasia” was published on the Center for Medicare and Medicaid Services (“CMS”) website by MAC Palmetto GBA. The proposed LCD is a further step in our efforts to secure Medicare coverage and payment for EsoGuard. The proposed LCD, which the CMS website explicitly characterizes as a “work in progress” for “public review,” outlines criteria that MolDX expects upper gastrointestinal precancer and cancer molecular diagnostic tests to meet. These criteria include active GERD with at least two risk factors, as well as evidence of analytic validity, clinical validity, and clinical utility. Although it found that no currently existing test has fulfilled all these criteria, it indicated that it will “monitor the evidence and will provide coverage based on the pertinent literature and society recommendations.” Notably, the proposed LCD pre-dated, and therefore does not include consideration of, the most recent ACG clinical guideline update endorsing swallowable, nonendoscopic capsule devices combined with a biomarker, such as EsoCheck and EsoGuard. The publication of the proposed LCD included a written comment period that extended through May 14, 2022. MolDX held an open meeting on May 10, 2022, during which stakeholders and other interested parties had the opportunity to address the proposed LCD. We have used the written comment process and the open meeting to bring to MolDX essential information that was not incorporated into the proposed LCD. These include: the updated ACG clinical guideline; the fact that EsoGuard’s published performance is at or above accepted performance criteria for detection of lower gastrointestinal cancers in approved and currently effective Medicare coverage determinations; and data from ongoing clinical utility studies Lucid and clinical investigators are performing. A final LCD will not be issued until the MAC has had the opportunity to assess and consider the comments and input from the written comment period and the open meeting. Following the MAC Palmetto GBA release of a proposed LCD, Noridian Healthcare Solutions published a proposed LCD entitled Molecular Testing for Detection of Upper Gastrointestinal Metaplasia, Dysplasia, and Neoplasia DL39262. The proposed LCD mirrors the MAC Palmetto GBA proposed LCD. We have used the Noridian Healthcare Solutions open meeting held on May 26, 2022, and the written comment period that ended on June 11, 2022 to bring the same essential information that we provided to the MAC Palmetto GBA to maintain consistency in our approach and advocate appropriately. EsoGuard BE-1 and BE-2 Clinical Trials In 2021 Lucid Diagnostics Inc. began conducting two concurrent clinical trials, including each of: the “EsoGuard screening study” (“BE-1”); and the “EsoGuard case-control study” (“BE-2”), to expand the clinical evidence for the technologies and to support a United States Food and Drug Administration (“FDA”) pre-market approval (“PMA”) of the use of EsoGuard and EsoCheck as an in-vitro diagnostic medical device (“IVD”). However, in light of the recently published proposed Local Coverage Determination (“LCD”) DL39256, the recently updated AGA guidance, and the ACG update to its clinical guideline that supports screening to prevent highly lethal esophageal cancer (“EAC”) utilizing our EsoGuard® DNA Test on samples collected with our EsoCheck® Cell Collection Device, the Company has determined to prioritize its clinical trial efforts and resources towards supporting studies that will help secure insurance reimbursement adoption by government and private insurers. Consequently, we have decided to delay for the time being the BE-1 trial while continuing to enroll GERD patients with a previous diagnosis of nondysplastic BE, low-grade dysplasia, high-grade dysplasia, or EAC in the BE-2 case-control study through Q2 2023. Recent Developments Business - continued MediNcrease Health Plans In May 2022 LucidDx Labs, Inc. entered into a participating provider agreement with MediNcrease Health Plans, LLC (“MediNcrease”). A national directly-contracted, multi-specialty PPO provider network with over 8 million lives covered through its clients and payers, which include regional and national health plans, insurance companies, third party administrators, self-insured employer groups, municipalities, unions and other entities involved in the management of medical claims. Pursuant to the agreement, persons covered by MediNcrease clients and payers will have in-network access to our EsoGuard® DNA test. The agreement provides rates of reimbursement as a percent of charges for services rendered to such covered persons by LucidDx Labs, including the performance of the EsoGuard® DNA test. In June and July 2022, LucidDx Labs Inc. continued to expand its in-network base by entering into participating provider agreements with Galaxy Health Network, Three Rivers Provider Network, and Prime Health Services (collectively, “the PPOs”), as well as Alivio Health. The PPOs cover millions of lives through the provider networks they have compiled for their clients, including third-party administrators, insurance companies, self-insured companies, corporations, and government entities to access, while Alivio provides its clients access to its specialized diagnostic laboratory network. Pursuant to the agreement, persons covered by the PPOs will have in-network access to our EsoGuard® DNA test. The agreements provides rates of reimbursement as a percentage of charges for services rendered to such covered persons by LucidDx Labs, including the performance of the EsoGuard test. Company-Owned Commercial Clinical Laboratory Through our wholly-owned subsidiary, LucidDx Labs Inc., we entered into an asset purchase agreement (“APA”) dated February 25, 2022, with ResearchDx, Inc. (“RDx”), an unrelated third-party - “APA-RDx”. Under the APA-RDx, LucidDx Labs Inc. acquired certain assets from RDx which were combined with LucidDx Labs purchased and leased property and equipment to establish a Company-owned CLIA certified, CAP accredited commercial clinical laboratory capable of performing the EsoGuard® Esophageal DNA assay, inclusive of DNA extraction, next generation sequencing (“NGS”) and specimen storage. Prior to consummation of the APA-RDx, RDx provided such laboratory services to us at its owned CLIA-certified, CAP-accredited clinical laboratory. Recent Developments Business - continued Third-Party Payor Billing and Revenue Cycle Management As part of the transition to our own Company-owned commercial clinical laboratory, we also contracted with a revenue cycle management (“RCM”) service provider to submit third-party reimbursement claims on our behalf. The RCM service provider will have complete oversight of payer claims, appeals processes, patient billing, online payment collection, and claims tracking. With the appropriate licenses and certifications for billing and credentialing secured, and our recently having put in place the necessary back office systems, claims for approximately 1,000 tests performed since the establishment of our own lab are now being processed, including 850 tests in the three months ended June 30, 2022 (although not having yet secured reimbursed rates from Medicare and Medicaid, the Company does not know the amount per claim it will receive from payors). Refer to Note 3 of our Condensed Consolidated Financial Statements for more information on Revenue from Contracts with Customers. Presently, recognized revenue for GAAP purposes is subject to actual amounts collected during the period. Accordingly, since the RCM began submitting claims processed from our own lab subsequent to June 30, 2022, there were no collections during the three months ended June 30, 2022. EsoCure License Agreement with PAVmed Inc. EsoCure has been in development as an esophageal ablation device by PAVmed. In April 2022, following the approval from both ours and the PAVmed Inc. boards of directors, we and PAVmed Inc. entered into an intercompany license agreement (“EsoCure License Agreement”), pursuant to which we were granted the rights to commercialize EsoCure. The EsoCure License Agreement, includes a royalty arrangement whereby we will pay PAVmed Inc. a 5% royalty on all EsoCure sales up to $100 million per calendar year, and an 8.0% royalty on annual sales in excess of $100 million per calendar year. We are obligated to reimburse PAVmed Inc. for any ongoing development costs and cumulative patent expenses associated with the licensed technology. CapNostics, LLC On October 5, 2021, PAVmed Subsidiary Corp, a wholly-owned subsidiary of PAVmed Inc., acquired 100% of the outstanding membership interest of CapNostics, LLC (“CapNostics”), an unrelated third-party, for total (gross) purchase consideration of approximately $2.1 million in cash, paid at the closing of the transaction. Subsequently, Lucid Diagnostics Inc. and PAVmed Subsidiary Corp entered into an agreement, effective April 1, 2022, pursuant to which PAVmed Subsidiary Corp assigned to Lucid Diagnostics Inc. 100% of the membership interest in CapNostics, LLC, inclusive of an acquired defensive technology intangible asset, and a $2.1 million payment obligation Due To: PAVmed Inc. Additionally, Lucid Diagnostics Inc. was also assigned on a prospective basis effective April 1, 2022, the consulting agreement with the previous principal owner of CapNostics, LLC. Results of Operations Overview Revenue Revenue was recognized with respect to the EsoGuard Commercialization Agreement, dated August 1, 2021, between the Company and ResearchDx Inc. (“RDx”), a CLIA certified commercial laboratory service provider. On February 25, 2022, the EsoGuard Commercialization Agreement was terminated upon the execution of an Asset Purchase Agreement between the Company’s wholly-owned subsidiary LucidDx Labs Inc. and RDx. Cost of revenue The cost of revenue recognized with respect to the revenue recognized under the EsoGuard Commercialization Agreement is inclusive of: a royalty fee incurred under the Amended CWRU License Agreement; the MSA Fee (as defined and discussed herein below) allocated to cost of revenue, which is principally employee related costs of PAVmed employees engaged in the administration to patients of the EsoCheck cell sample collection procedure (principally at the LUCID Test Centers); the EsoCheck devices and EsoGuard mailers (cell sample shipping costs) distributed to medical practitioners locations and the LUCID Test Centers; and LUCID Test Centers operating expenses, including rent expense and supplies. Sales and marketing expenses Sales and marketing expenses consist primarily of the portion of the MSA Fee allocated to sales and marketing expenses, which are principally employee related costs of PAVmed employees, as well as advertising and promotion expenses. We anticipate our sales and marketing expenses will increase in the future, as we anticipate an increase in payroll and related expenses related to the roll-out of our commercial sales and marketing operations as we execute on our business strategy. General and administrative expenses General and administrative expenses consist primarily of professional fees, accounting and legal services, consultants and expenses associated with obtaining and maintaining patents within our intellectual property portfolio, along with the portion of the MSA Fee allocated to general and administrative expenses. We anticipate our general and administrative expenses will increase in the future, as we anticipate an increase in the MSA Fee allocated to general and administrative expense, related to continued expansion of our overall business operations. We also anticipate expenses related to being a public company, including professional services fees for legal, accounting, tax, audit, employees involved in third-party payor reimbursement contract negotiations and regulatory services associated with maintaining compliance as a public company, along with insurance premiums, investor relations, and other corporate expenses. Results of Operations Overview - continued Research and Development Expenses Research and development expenses are recognized in the period they are incurred and consist principally of internal and external expenses incurred for the development of our technologies and conducting clinical trials, including: ● consulting costs charged to us by various external contract research organizations we contract with to conduct preclinical studies and engineering studies; ● costs associated with regulatory filings; ● patent license fees; ● cost of laboratory supplies and acquiring, developing, and manufacturing preclinical prototypes; ● product design engineering studies; ● fees associated with conducting clinical trials for our EsoGuard diagnostic assay; and ● MSA Fee allocated to research and development, as such MSA Fee are discussed below.
