Estrella Immunopharma, Inc. (NASDAQ:ESLA) has announced a major milestone in its STARLIGHT-1 Phase I/II clinical trial, dosing the first patient in the second cohort of its dose escalation study for EB103.
EB103 is an innovative CD19-redirected ARTEMIS T-cell therapy designed to treat advanced B-cell Non-Hodgkin’s Lymphomas (NHL). This next phase follows a successful first cohort, which reported no dose-limiting toxicities or serious adverse events, and even saw a complete response in one patient.

The second cohort will test EB103 at a higher dose, aiming to further establish safety and efficacy. Estrella Immunopharma, Inc.’s CEO, Cheng Liu, highlighted the therapy’s potential to overcome limitations of conventional CAR-T treatments, particularly for high-risk groups such as patients with HIV-associated or CNS lymphomas, populations often excluded from current therapies.
EB103 leverages proprietary ARTEMIS technology, allowing T-cells to more precisely target and destroy cancer cells. Estrella Immunopharma, Inc.’s pipeline also includes EB104, targeting both CD19 and CD22 proteins found in most B-cell malignancies. The company’s progress signals hope for broader, safer, and more effective immunotherapies for cancer and autoimmune disease patients.
