Venetoclax, Daratumumab, and Dexamethasone for Systemic Light-Chain Amyloidosis With Translocation (11;14) (ALTITUDE)

Conditions

AL Amyloidosis Light Chain (AL) Amyloidosis Systemic Light Chain Disease Translocation

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This phase I/II trial tests the safety, side effects, and best dose of venetoclax, daratumumab, and dexamethasone for the treatment of systemic light-chain amyloidosis in patients with a deoxyribonucleic acid (DNA) abnormality called a translocation involving chromosomes 11 and 14, or "t(11;14)". Venetoclax works by attaching to a protein called Bcl-2, in order to kill cancer cells. Daratumumab works by binding to a target on the surface of cancer cells called Cluster of differentiation 38 (CD38). When daratumumab binds to CD38, it enables the immune system to find the cancer cell and kill it. Dexamethasone is a type of drug called a corticosteroid. A corticosteroid is a drug made of artificial steroid hormones, that are used to treat symptoms such as inflammation (swelling and irritation to a part of the body). The combination of these medications may more effectively treat patients with systemic light-chain amyloidosis and t(11;14).
