IM19 CAR-T cells / Beijing Imunopharm, Simcere - LARVOL DELTA

Phase I Study of a CD19-Directed CAR-T Cell Therapy for Relapsed/Refractory Mantle Cell Lymphomas(MCL) (ASH 2024) - "Lymphodepleting (LD) chemotherapy was administered over 3 days, including fludarabine (30 mg/m2 i.v. daily) and cyclophosphamide (300 mg/m2 i.v. daily), followed 2 days later by intravenous infusion of IM19 at the assigned dose. We observed that CAR-T cells cannot expand in vivo after secondary infusion. Therefore, secondary infusion may not be necessary."

Huadong Medicine deepens its presence in the CAR-T field and pays a down payment of RMB 125 million to introduce ImmunoChina IM19 CAR-T cell injection [Google translation] (Eastmoney.com) - "...Huadong Medicine...has signed an exclusive product commercialization cooperation agreement with Beijing ImmunoPharma...Huadong Medicine...has obtained the exclusive commercialization rights of ImmunoPharma's...product IM19...in mainland China. Huadong Medicine...will pay ImmunoPharma a down payment of RMB 125 million...The announcement shows that IM19 CAR-T cell injection has successively obtained drug clinical trial approval notices for three indications: relapsed and refractory diffuse large B-cell lymphoma (r/r-DLBCL), acute B-lymphocytic leukemia (B-ALL) and mantle cell lymphoma (MCL), and has all entered the registration clinical research stage. Among them, the research on the last-line treatment of diffuse large B-cell lymphoma is about to complete the Phase II clinical trial....with good clinical efficacy and safety data, and it is expected to submit a drug marketing authorization application in the fourth quarter of 2024."

Phase I Study of a CD19-Directed CAR-T Cell Therapy for Relapsed/Refractory Mantle Cell Lymphomas(MCL) (ASH 2023) - "Lymphodepleting (LD) chemotherapy was administered over 3 days, including fludarabine (30 mg/m2 i.v. daily) and cyclophosphamide (300 mg/m2 i.v. daily), followed 2 days later by intravenous infusion of IM19 at the assigned dose. Initial data from this Phase I study demonstrate that use of IM19 resulted in a high objective response rate, with a low incidence of grade 3 or worse cytokine release syndrome and neurological events in patients with relapsed or refractory MCL. We observed that CAR-T cells cannot expand in vivo after secondary infusion. Therefore, secondary infusion may not be necessary."

The pivotal clinical study of IM19 CAR-T cells in the treatment of relapsed or refractory aggressive B cell non-Hodgkin lymphomas (ESMO Asia 2023) - P1/2 | "The incidences of CRS and neurotoxicity were 42% and 7%, respectively; no patient experienced grade 3-4 CRS or grade 3-4 neurotoxicity. Conclusions IM19 treatment of patients with relapsed or refractory aggressive non-Hodgkin's lymphoma can achieve a high rate of durable responses, with an extremely low incidence of grade 3 or more severe CRS and neurotoxicity."

A durable 4-1BB-based CD19 CAR-T cell for treatment of relapsed or refractory non-Hodgkin lymphoma. (PubMed, Chin J Cancer Res) - "However, the median progression-free survival (mPFS) of 4-1BB-based product Kymriah was shorter than that of CD28-based Yescarta (2.9 monthsvs. 5.9 months), suggesting that Kymriah was limited in the long-term efficacy. Only one patient (4.5%) experienced grade 3 CRS and grade 3 neurotoxicity. These results demonstrated the safety and durable efficacy of a 4-1BB-based CD19 CAR-T, IM19, which is promising for further development and clinical investigation."
