Summary

This trial is testing a new drug called linvoseltamab for patients with AL amyloidosis that has come back or not responded to other treatments. The trial has two phases: Phase 1

Who is the study for?
This trial is for adults with AL amyloidosis who have tried at least one but no more than four treatments and need more therapy. They should have a certain level of abnormal proteins in their blood, be able to perform daily activities with ease or some difficulty (ECOG score ≤2), and have good heart, liver, kidney, and blood function.
What is being tested?
The study tests linvoseltamab in two phases: Phase 1 determines safe dosages through a small group; Phase 2 expands the testing for effectiveness against AL amyloidosis symptoms. It also examines how long improvements last, optimal dosing schedules, potential side effects, drug levels in the blood over time, and if the body resists the drug.
What are the potential side effects?
Possible side effects include reactions related to immune response against linvoseltamab which could reduce its effectiveness or cause additional issues. The study will monitor how much of the drug stays in participants' systems and any organ-specific inflammation or other adverse reactions.
