About this trial
Phase I:
Primary Objective:
\- Determine the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D) of the o-Dec, ven, and HCQ
Secondary Objectives:
* Characterize the safety profile of the triplet * Estimate the efficacy of the combination to induce remission

Treatments tested in this trial
Hydroxychloroquine
DrugHydroxychloroquine will be administered orally as part of a combination regimen with Decitabine (oral decitabine-cedazuridine) and Venetoclax. In the Phase I portion, hydroxychloroquine will be given at escalating dose levels using a BOIN design to determine the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D).
Venetoclax
DrugVenetoclax is a potent, selective, orally bioavailable small-molecule inhibitor of the anti-apoptotic protein B-cell lymphoma-2 (BCL-2). It promotes apoptosis of malignant cells that are dependent on BCL-2 for survival. Venetoclax will be supplied through the study participants' commercial pharmacy. Venetoclax is supplied as film-coated oral tablets containing 10 mg, 50 mg, or 100 mg of active drug. Tablets are intended for oral administration only. No reconstitution or dilution is required
Oral Decitabine/cedazuridine
DrugOral decitabine/cedazuridine is a fixed-dose combination of decitabine, a hypomethylating agent (DNA methyltransferase inhibitor), and cedazuridine, a cytidine deaminase inhibitor that increases oral bioavailability of decitabine by preventing its rapid degradation in the gut and liver. Each tablet contains 35 mg decitabine and 100 mg cedazuridine. The combination provides systemic exposure comparable to that of IV decitabine 20 mg/m² given over 5 days. Oral decitabine/cedazuridine will be obtained through the study participant's commercial pharmacy.
