Sage Supports Lucid Diagnostics’ Bold Vision for Advancing EsoCheck

Lucid Diagnostics' EsoCheck

A quick, non-invasive way for clinicians to collect esophageal cells for analysis, without endoscopy. Lucid’s proprietary Collect+Protect™ technology ensures EsoCheck’s unique capability for anatomically targeted and protected sampling of esophageal cells.

Summary

According to the Annals of Esophagus, GERD, also known as chronic heartburn, is currently one of the most common gastrointestinal (GI) diagnoses with substantial impact on patients’ quality of life and high healthcare resource utilization. The journal states that its diagnosis is convoluted, and management is complex. As a result, primary care physicians (PCP) frequently find it challenging to choose appropriate care strategies, especially when initial interventions fail.

Lucid Diagnostics, a subsidiary of PAVmed Inc. (Nasdaq: PAVM), is a commercial-stage medical diagnostics company focused on cancer prevention. Lucid decided to take on this complicated challenge and address the needs of the millions of patients with GERD who are at risk of developing esophageal precancer and cancer. Lucid achieved a significant milestone with the development of EsoCheck, a device that aligns with the company’s mission to empower clinicians to save lives by accurately detecting Barrett's Esophagus (BE) in an office setting at a stage when it can be effectively managed or treated to prevent progression to highly lethal esophageal cancer.

EsoCheck is a is a quick, non-invasive way for clinicians to collect esophageal cells for analysis, without endoscopy. The device consists of a vitamin-sized, semi-rigid plastic capsule tethered to a thin silicone catheter. A soft inflatable silicone balloon with textured ridges emerges to gently swab surface esophageal cells. When suction is applied, the balloon and sampled cells are pulled into the capsule, protecting them from contamination and dilution by cells outside the targeted region during device withdrawal. Lucid’s proprietary Collect+Protect™ technology ensures EsoCheck’s unique capability for anatomically targeted and protected sampling of esophageal cells.

CASE STUDY: Sage Supports Lucid’s Bold Vision for Advancing EsoCheck

Lucid’s forward-thinking vision and commitment to advancing EsoCheck’s potential led the company to seek a partner capable of matching their determination and purpose. Recognizing Sage’s extensive expertise in medical device development, manufacturing, and support of regulatory submissions, Lucid collaborated with Sage to achieve an ambitious set of goals within a highly condensed timeline. Together, the companies achieved a groundbreaking result.

Challenges: Turning an Impressive Plan into Reality

In July 2018, Lucid’s Chief Technology Officer reached out to Sage with a bold objective: to submit EsoCheck for FDA 510(k) clearance with an extremely tight timeline, an objective that would require incredible work ethic, communication, and focused attention to detail. Lucid’s confidence in their innovative device and their strategic decision to partner with Sage underscored their determination to bring life-saving technology to market quickly.

Lucid tasked Sage with finalizing design inputs, building fixtures, completing design verification testing, and writing test reports which would be necessary for the FDA submission. This required a collaborative, strategic approach to meet the accelerated timeline while maintaining rigorous quality standards.


From Vision to Submission

Sage’s team immediately initiated the Design and Development phase, working closely with Lucid to refine and document the device design. Sage developed a comprehensive Design History File, test methods, procedures, test fixtures, and conducted design verification testing efficiently, with great precision and reliability.


“The nature of what we do requires incredible accuracy, so it is critical to get everything right the first time,” said Peter Aliski, Sage’s General Manager.

Through close collaboration and meticulous planning, Lucid and Sage successfully completed the project by the deadline, resulting in a 510(k) submission to the FDA. Lucid’s clear vision, combined with Sage’s technical expertise, ensured the device met stringent industry standards while addressing the needs of healthcare professionals and patients.


Flexibility and Collaboration to Expand the Scope of Work

Impressed by Sage’s ability to deliver results under pressure, Lucid expanded the scope of their collaboration. This included supply chain management and manufacturing. Once commercialized, the demand for Esocheck quickly began to rise in the market. Having developed a robust manufacturing process, the Sage team continued to build product to meet existing demand, while simultaneously working in parallel to provide a seamless transfer to a higher volume manufacturer.

“We viewed any challenges as opportunities to continue supporting our client and ensuring their product reached the market,” said Jeff Cerier, President, and Co-founder of Sage.

Achieving Success and Industry Recognition

The collaboration resulted in the successful FDA 510(k) clearance for EsoCheck, which is now commercially available to clinicians. In 2020, EsoCheck was named a “Silver” winner of the Edison Best New Product Awards in the “Medical/Dental Testing Solutions” category, a prestigious honor recognizing excellence in innovation, design, and development.


Conclusion

Lucid Diagnostics’ bold vision and commitment to innovation, combined with Sage’s expertise and adaptability, exemplify the power of collaboration in advancing healthcare technologies. By successfully completing testing that supported 510(k) clearance, manufacturing the product, and facilitating the transfer to a high-volume manufacturer, the partnership brought EsoCheck to market on an accelerated timeline. This achievement not only underscores Lucid’s leadership in the medical diagnostics field but also highlights Sage’s proficiency in taking on complex challenges and commitment to advancing patient outcomes.
