OncoCyte (NASDAQ: OCX), a small California-based biotech, is aiming to revolutionize organ transplant monitoring. While their partnership with Bio-Rad Laboratories has drawn attention for its potential in the transplant monitoring sector, a subtle but powerful detail emerged from OncoCyte's recent earnings call: their strategic pursuit of a "single site" FDA approval pathway.

This unique regulatory approach could enable OncoCyte to achieve a rapid transition from centralized, expensive, and slow lab-based testing to a widely distributed, cost-effective, and rapid in-house model. This shift could significantly enhance access to transplant rejection monitoring, potentially leading to earlier detection, improved outcomes, and ultimately, saved lives.

CEO Josh Riggs outlined OncoCyte's plan to establish a "predicate device" through the FDA's single-site process, utilizing their existing CLIA-certified lab in Nashville. This lesser-known regulatory route is often used for lower-risk devices. By obtaining FDA clearance for their lab-developed test (LDT) in Nashville, OncoCyte can then leverage this approval to expedite the clearance of their kitted version, VitaGraft Kidney IVD, without extensive additional clinical trials.

The implications are significant. OncoCyte could potentially shave months, if not years, off their timeline to commercialize VitaGraft Kidney IVD, getting their product into transplant centers faster. While market leaders are focused on the lucrative U.S. market with their centralized lab model, OncoCyte could leapfrog them, capitalizing on the global demand for localized testing solutions.

Global Transplant Market Potential

The global transplant market is substantial, with over 157,000 transplants annually and a robust 9.1% growth rate. Even capturing a fraction of this market presents enormous revenue potential for OncoCyte. Riggs suggested a scenario where 30 to 50 centers, or more, in both the U.S. and EU could adopt their in-house test, generating over $100 million in annual recurring revenue.

Beyond Kidney Transplants: Expanding Applications

OncoCyte's technology has applications beyond kidney transplants. The company is exploring liver transplant monitoring, a market with significant unmet needs, especially in immunosuppression tapering. This could allow patients to safely reduce their reliance on immunosuppressive drugs, improving quality of life and minimizing long-term side effects.

Challenges and Potential

OncoCyte's success hinges on navigating the single-site FDA process and securing reimbursement for their kitted product. The recently released final rule for LDT regulation could also pose challenges, but OncoCyte believes their current LDTs meet the "currently marketed" carve-out and the phasing period provides ample time for adjustments.

However, if OncoCyte succeeds, the potential for both financial success and medical advancements is considerable. Their commitment to democratizing diagnostic testing, making it more accessible and affordable, could transform them into a major player in the global healthcare landscape.
