Venetoclax added to reduced-intensity conditioning for combined stem cell and kidney transplant
Official title: Addition of Venetoclax to Combined Reduced Intensity Hematopoietic Stem Cell and Kidney Transplantation for Patients With Chronic Kidney Disease and Hematologic Malignancy
Run by Massachusetts General Hospital · NCT07358195 · Data updated 2026-11-12
This trial tests whether adding venetoclax to a reduced-intensity conditioning regimen is safe for adults with blood cancers who are receiving a combined stem cell and kidney transplant from a matched or partially matched donor.

Is this trial a fit for you?
✓Likely a good fit
Adults 18-70 with a hematologic malignancy potentially curable by allogeneic transplant, an eligible matched or haploidentical donor, and adequate organ function.
✕Probably not a fit
Patients without matching donors or who do not achieve stable donor hematopoiesis may not experience benefit.

What this trial studies
This early-phase trial aims to evaluate the safety of adding venetoclax to a reduced-intensity conditioning protocol before a combined hematopoietic stem cell and kidney transplant. Participants are adults with a potentially curable hematologic malignancy and an available matched or haploidentical donor. The primary endpoint is stable donor hematopoiesis without severe venetoclax-related toxicity (CTCAE grade IV or V). The study uses a venetoclax-containing conditioning regimen along with kidney transplantation and donor stem cell transplantation. Enrollment is limited to patients at Massachusetts General Hospital with specific physiologic and organ function criteria.
Why it matters
Potential benefit: If successful, the approach could improve engraftment and transplant safety for patients undergoing combined stem cell and kidney transplantation.
How similar studies have gone: Prior approaches using venetoclax in conditioning show potential but this exact combined transplant with venetoclax is novel and exploratory.
