In the dose escalation phase, 12 Non-Hodgkin Lymphoma (NHL) patients treated with 100×10⁶–200×10⁶ cells showed a 66% objective response rate, including 50% complete response. Responses lasted 3–24 months, with five patients maintaining response at least six months. Safety was strong across all doses (100×10⁶–400×10⁶ cells). No dose-limiting toxicities or immune-effector cell associated neurotoxicity syndrome (ICANS) occurred. Two cases of mild cytokine release syndrome were reported, and no serious adverse events were observed. The study will now move into a dose expansion phase at 400×10⁶ cells in patients with diffuse large B-cell lymphoma who have relapsed after or are ineligible for CAR-T therapy. A live webcast to discuss these findings will be held today at 8:30 a.m. ET, with a replay available on the company’s website.Read AnnouncementProvided Update - December 19,2024Provided Update Phase 1Drug: MT-601Announced Date: December 19, 2024Indication: Pancreatic cancerAnnouncementMarker Therapeutics, Inc. provided an update on the progress and clinical observations from the Phase 1 APOLLO study, with a data cutoff date of September 10.AI SummaryMarker Therapeutics, Inc. provided an update on the Phase 1 APOLLO study for MT-601, a multi-antigen recognizing T cell therapy for patients with relapsed lymphoma. The study, with data cut off on September 10, showed promising early results. Out of 9 patients treated at 5 clinical sites in the United States, 78% achieved objective responses and 44.4% experienced complete responses at the initial assessment. MT-601 was well tolerated, with no reports of immune-effector cell associated neurotoxicity syndrome and only one case of Grade 1 cytokine release syndrome.
