Estrella Immunopharma shares rallied on Wednesday following an update on the STARLIGHT-1 clinical trial. The study evaluates the efficacy and safety of the experimental drug EB103 in patients with relapsed or refractory B-cell non-Hodgkin's lymphoma.
Why it matters
The company provided a positive update on the STARLIGHT-1 clinical trial safety results, which signals potential progress for their proprietary cell therapy. These data points from the dose-expansion phase are expected to inform the firm's future pivotal trial strategy.
The EB103 treatment utilizes ARTEMIS technology licensed from Eureka Therapeutics. The first patient in the expansion phase received two infusions of 5 × 10⁶ T cells per kilogram three weeks apart.
