Detailed Description

This study is a phase 1/2 study of venetoclax-dexamethasone combination therapy in relapsed/refractory t(11;14) systemic immunoglobulin light chain amyloidosis (AL) amyloidosis. The phase 1 is a dose escalation designed to determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) of venetoclax in combination with low-dose weekly dexamethasone. There will be four candidate-dosing cohorts of venetoclax with or without dexamethasone in the Phase I dose-escalation. Dose escalation will be guided by the Bayesian optimal interval (BOIN) design with accelerated titration up to a total sample size of 15 participants. The phase 2 portion is a randomized open-label study comparing the MTD or RP2D of venetoclax in combination with dexamethasone versus investigator's choice (daratumumab, pomalidomide, bendamustine, or ixazomib (with or without dexamethasone).
