A Phase I/II, Open Label, Study to Evaluate Safety, Tolerability and Efficacy of Elranatamab in Patients With Relapsed or Refractory AL Amyloidosis

Trial Purpose and Description

This is a Phase I/II, multi-center, open-label study designed to evaluate the safety, tolerability and efficacy of elranatamab in patients with relapsed or refractory light chain (AL) amyloidosis. Phase 1 will enroll 4-20 participants, beginning enrollment at Dose Level 0. If two or more participants at Level 0 experience DLT, dose will be decreased to Level -1. Each participant will complete the 28-day dose-limiting toxicity (DLT) evaluation period prior to dosing the next patient. Assuming a recommended phase 2 dose (RP2D) is found, Phase 2 will enroll an additional 29 participants for a total of 49 participants.
