Study Evaluating the Safety and Pharmacokinetics of JCAR017 in B-cell Non-Hodgkin Lymphoma (TRANSCEND-NHL-001)

This is an open-label, multicenter Phase 1 study to determine the safety, pharmacokinetics (PK), and antitumor activity of JCAR017 in adult patients with relapsed or refractory diffuse large B cell lymphoma (DLBCL), primary mediastinal B-cell lymphoma (PMBCL), follicular lymphoma Grade 3B, and mantle cell lymphoma (MCL). This study will evaluate and refine the dose and schedule of JCAR017 to optimize safety and antitumor activity. A dose-confirmation group or groups will further evaluate the safety and efficacy of JCAR017 at the recommended regimen(s). Upon successful generation of JCAR017 product, participants will receive treatment with one or more cycles of JCAR017 therapy. Each cycle will include lymphodepleting chemotherapy followed by one or two doses of JCAR017 administered by intravenous (IV) injection. The follow-up period for each participant is approximately 24 months after the final JCAR017 infusion. Long-term follow-up for survival, toxicity, and viral vector safety will continue under a separate long-term follow-up protocol per health regulatory authority guidelines, currently up to 15 years after the last JCAR017 infusion.
