Business Update Highlights

"We are very pleased with the excellent progress Lucid has made on multiple fronts in the fourth quarter and recent weeks," said Lishan Aklog, M.D., Lucid's Chairman and Chief Executive Officer. "We saw solid revenue growth on stable test volume and our revenue cycle management processes are yielding improving allowances and stable pricing. Our #CYFT program targeting firefighters and other groups is thriving and we have a robust pipeline of scheduled high-volume testing events. Most importantly, we have rapidly built our clinical validity and clinical utility evidence base to drive positive medical policy coverage, including what now we believe is line of sight to Medicare coverage. Equipped with sufficient data, we have for the first time engaged with medical directors at major commercial payors to request positive coverage. Our direct contracting initiative is also accelerating and we are excited about the near-term prospects of delivering contracts, testing and revenue." 

Highlights from the fourth quarter and recent weeks include:

  • 4Q23 EsoGuard revenue was $1.04M, which represents a 33 percent increase sequentially from 3Q23 and an 829 percent annual increase from 4Q22.
  • Lucid's CLIA-certified clinical laboratory performed 2,201 commercial EsoGuard® Esophageal DNA Tests in 4Q23.
  • High-volume #CYFT health fair testing events continue to gain traction with a robust roster of events scheduled through July.
  • Lucid initiated EsoGuard testing at over a dozen strategic accounts at health systems and academic medical centers with several dozen more engagements in process.
  • Since upgrading to a new revenue cycle management provider in mid-June, Lucid has submitted claims to commercial and governmental payors representing approximately $20 million in pro forma revenue. The vast majority of these claims have been adjudicated with nearly half resulting in an allowable amount of approximately $1,800 per test, on average.
  • EsoGuard's clinical validity and clinical utility data evidence base has expanded significantly in the fourth quarter and recent months. Lucid now has publicly-released data from three clinical validity studies demonstrating excellent EsoGuard sensitivity and negative predictive value, including unprecedented performance of a molecular diagnostic test in detecting precancer. In addition, three published clinical utility studies have documented near-perfect concordance between EsoGuard results and physician referral for upper gastrointestinal endoscopy. These data provide a strong foundation of critical evidence needed to support broad EsoGuard medical policy coverage. Lucid expects to leverage this data in its upcoming re-engagement with the MolDX program to secure Medicare coverage under the final and effective foundational Local Coverage Determination.
  • Held several meetings in recent months with medical directors of major commercial payors to discuss clinical validity and utility data and formally request positive medical policy determinations for EsoGuard. The Company also participated in a Blue Cross Blue Shield Association of America webinar with dozens of medical directors in attendance, during which Nicholas Shaheen, M.D., M.P.H., a leading esophageal precancer expert and lead author of the American College of Gastroenterology's guidelines, advocated for coverage of non-endoscopic biomarker testing consistent with the ACG guidelines. Lucid also expects recent expansion of legislation requiring coverage of certain biomarker tests, now effective in fourteen states, will help drive medical policy coverage.
  • Established that EsoGuard testing can be offered as a covered benefit within health and wellness programs as a means to drive contractually-guaranteed revenues. Lucid has built a robust pipeline of direct contracting counterparties, including benefits brokers, third-party administrators, and self-insured entities. The Company expects to drive direct contract testing events with meaningful revenues in the coming quarters. The Company is adding resources to the direct contracting team to accelerate this initiative

Lucid Non-GAAP Measures

  • To supplement our audited financial results presented in accordance with U.S. generally accepted accounting principles (GAAP), management provides certain non-GAAP financial measures of the Company's financial results. These non-GAAP financial measures include net loss before interest, taxes, depreciation, and amortization (EBITDA), and non-GAAP adjusted loss, which further adjusts EBITDA for stock-based compensation expense and other non-cash income and expenses, if any. The foregoing non-GAAP financial measures of EBITDA and non-GAAP adjusted loss are not recognized terms under U.S. GAAP.
  • Non-GAAP financial measures are presented with the intent of providing greater transparency to the information used by us in our financial performance analysis and operational decision-making. We believe these non-GAAP financial measures provide meaningful information to assist investors, shareholders, and other readers of our audited financial statements in making comparisons to our historical financial results and analyzing the underlying performance of our results of operations. These non-GAAP financial measures are not intended to be, and should not be, a substitute for, considered superior to, considered separately from, or as an alternative to, the most directly comparable GAAP financial measures.
  • Non-GAAP financial measures are provided to enhance readers' overall understanding of our current financial results and to provide further information for comparative purposes. Management believes the non-GAAP financial measures provide useful information to management and investors by isolating certain expenses, gains, and losses that may not be indicative of our core operating results and business outlook. Specifically, the non-GAAP financial measures include non-GAAP adjusted loss, and its presentation is intended to help the reader understand the effect of the loss on the issuance or modification of convertible securities, the periodic change in fair value of convertible securities, the loss on debt extinguishment, and the corresponding accounting for non-cash charges on financial performance. In addition, management believes non-GAAP financial measures enhance the comparability of results against prior periods.

About EsoGuard and EsoCheck

Millions of patients with GERD are at risk of developing esophageal precancer and a highly lethal form of esophageal cancer ("EAC"). Over 80 percent of EAC patients die within five years of diagnosis, making it the second most lethal cancer in the U.S. The mortality rate is high even in those diagnosed with early stage EAC. The U.S. incidence of EAC has increased 500 percent over the past four decades, while the incidences of other common cancers have declined or remained flat. In nearly all cases, EAC silently progresses until it manifests itself with new symptoms of advanced disease. All EAC is believed to arise from esophageal precancer, which occurs in approximately 5 percent to 15 percent of at-risk GERD patients. Early esophageal precancer can be monitored for progression to late esophageal precancer which can be cured with endoscopic esophageal ablation, reliably halting progression to cancer.

Esophageal precancer screening is already recommended by clinical practice guidelines in millions of GERD patients with multiple risk factors, including age over 50 years, male gender, White race, obesity, smoking history, and a family history of esophageal precancer or cancer. Unfortunately, fewer than 10 percent of those recommended for screening undergo traditional invasive endoscopic screening. The profound tragedy of an EAC diagnosis is that likely death could have been prevented if the at-risk GERD patient had been screened and then undergone surveillance and curative treatment.

The only missing element for a viable esophageal cancer prevention program has been the lack of a widespread screening tool that can detect esophageal precancer. Lucid believes EsoGuard, performed on samples collected with EsoCheck, is the missing element – the first and only commercially available test capable of serving as a widespread screening tool to prevent esophageal cancer deaths through the early detection of esophageal precancer in at-risk GERD patients. An updated American College of Gastroenterology clinical practice guideline and an American Gastroenterological Association clinical practice update both endorse non-endoscopic biomarker tests as an acceptable alternative to costly and invasive endoscopy for esophageal precancer screening. EsoGuard is the only such test currently available in the United States.

EsoGuard is a bisulfite-converted NGS DNA assay performed on surface esophageal cells collected with EsoCheck, which quantifies methylation at 31 sites on two genes, Vimentin (VIM) and Cyclin A1 (CCNA1). The assay was evaluated in a 408-patient, multicenter, case-control study published in Science Translational Medicine and showed greater than 90 percent sensitivity and specificity at detecting esophageal precancer and cancer.

EsoCheck is an FDA 510(k) and CE Mark cleared noninvasive swallowable balloon capsule catheter device capable of sampling surface esophageal cells in a less than five-minute office procedure. It consists of a vitamin pill-sized rigid plastic capsule tethered to a thin silicone catheter from which a soft silicone balloon with textured ridges emerges to gently swab surface esophageal cells. When vacuum suction is applied, the balloon and sampled cells are pulled into the capsule, protecting them from contamination and dilution by cells outside of the targeted region during device withdrawal. Lucid believes this proprietary Collect+Protect™ technology makes EsoCheck the only noninvasive esophageal cell collection device capable of such anatomically targeted and protected sampling. The sample is sent by overnight express mail to Lucid's CLIA-certified, CAP-accredited laboratory, LucidDx Labs, for EsoGuard testing.
