Study to Assess Safety, Efficacy, and Cellular Kinetics of YTB323 in Generalized Myasthenia Gravis
brief summary
This is a phase I/II study to assess safety, efficacy, and cellular kinetics of YTB323 in participants with treatment-resistant generalized myasthenia gravis. YTB323 is a Biological CAR-T cell therapy.
detailed description
This is an open-label, multi-center, non-confirmatory study intended to assess safety, efficacy, and cellular kinetics of YTB323 treatment in participants with treatment-resistant generalized myasthenia gravis in order to enable a benefit to risk assessment for further development in generalized myasthenia gravis (gMG). The study plans to enroll approximately 15 participants with treatment-resistant gMG. The study utilizes a single dose design across 2 cohorts, consisting of a sentinel cohort of 3 patients followed by an expansion cohort of an additional 12 patients.
All participants dosed with YTB323 will be followed until 15 years after YTB323 administration in the Long-Term Follow-up (LTFU).
