Summary

This trial is designed to find the best dose of STI-6129 to treat relapsed or refractory systemic AL amyloidosis while also assessing its safety and preliminary efficacy.

Who is the study for?
This trial is for adults with relapsed or refractory systemic AL amyloidosis who've had prior treatments. They must have measurable disease, be able to perform daily activities with minimal assistance (ECOG 0-2), and not be pregnant or breastfeeding. Participants should agree to use birth control and cannot have severe heart issues, certain infections like HIV/HBV/HCV, other recent cancers, or poor organ function.
What is being tested?
The study tests STI-6129, an antibody-drug conjugate targeting CD38 in patients with AL amyloidosis that has come back or didn't respond to treatment. It's a multi-stage trial aiming to find the safest and most effective dose by observing how well it works and how the body processes it.
What are the potential side effects?
Potential side effects of STI-6129 are not explicitly listed but may include reactions related to immune system activation against cancer cells, infusion-related responses, impact on blood counts and organ functions based on its mechanism as an antibody-drug conjugate.
