What this trial studies

This open-label, first-in-human Phase 1/2 study uses a dose-escalation and expansion design to test NEO-811 initially as a monotherapy in subjects with locally advanced or metastatic non-resectable clear cell renal cell carcinoma. Eligible participants must have measurable disease by RECIST v1.1, ECOG performance status 0 or 1, adequate blood and organ function, and available tumor tissue (new or archival FFPE). The trial will enroll at multiple U.S. sites and will determine a safe dose range and collect early evidence of anti-tumor activity and safety signals. Safety, tolerability, and preliminary efficacy endpoints will guide dose selection for expansion cohorts.

Who should consider this trial

Good fit: Adults with locally advanced or metastatic non-resectable clear cell renal cell carcinoma who have progressed on or refused standard therapies, have ECOG 0–1, measurable disease, adequate organ function, and available tumor tissue are ideal candidates.

Not a fit: Patients with non–clear-cell kidney cancers, poor performance status, inadequate organ function, inability to swallow oral medication, or unwillingness/unable to provide tumor tissue are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, NEO-811 could shrink tumors or slow disease progression and provide a new therapy option for patients with advanced ccRCC who have limited choices.

How similar studies have performed: NEO-811 is being tested in humans for the first time; while targeted therapies and immunotherapies have improved outcomes in ccRCC, this specific agent has not yet been studied in people.
