Lyell Immunopharma Releases New Data on Ronde-cel Therapy
- Clinical Trial Progress: As of May 5, 2026, a total of 108 patients with relapsed or refractory large B-cell lymphoma have been treated with ronde-cel, including 43 in the second-line and 65 in the third-line or later settings, demonstrating the therapy's efficacy in high-risk populations.
- Safety Analysis: No Grade 3 or higher cytokine release syndrome (CRS) events were reported among patients treated with ronde-cel, and among those receiving dexamethasone prophylaxis, Grade 1 CRS occurred in 56%, indicating a favorable safety profile that supports outpatient administration.
- Durable Responses: The study indicates that cytotoxic T cells with memory potential are more abundant in patients with durable responses, providing a biological rationale for the high rates of complete responses observed in patients with low antigen expression tumors, suggesting significant therapeutic potential.
- Future Outlook: The PiNACLE clinical trial is expected to update data in the second half of 2026, with pivotal data readout anticipated in mid-2027, followed by a Biologics License Application (BLA) submission in the second half of 2027, paving the way for market introduction of ronde-cel.
