This is a Phase 1 open-label, multi-center safety and dose-escalation study of anito-cel in adult participants with GMG (MGFA Grade 2 to 4a), in whom immunosuppressive therapy is clinically indicated in the judgement of the treating neurologist. The primary objective of this study is to assess the safety profile, including any DLT and identification of a MTD (if applicable), to support selection of the RP2D of anito-cel when administered to participants with GMG.
The study will have the following sequential phases: screening, enrollment (leukapheresis), pretreatment with lymphodepletion (LD) chemotherapy, treatment with anito-cel and follow-up. Optional bridging therapy is allowed at investigator discretion while anito-cel is being manufactured.
Following a single infusion of anito-cel both safety and efficacy data will be assessed. The DLTs will be assessed in the first 28 days following anito-cel administration, and safety data will be collected throughout the study.
