Lymphodepletion and Anti-PD-1 Blockade to Reduce Relapse in AML Patient Not Eligible for Transplant
September 22, 2023 updated by: Northside Hospital, Inc.
Phase II Trial of Lymphodepletion and Anti-PD-1 Blockade to Reduce Relapse in High Risk AML Patients Who Are Not Eligible for Allogeneic Stem Cell Transplantation
AML is the most common acute leukemia in adults.
Most patients can undergo allogeneic stem cell transplantation as a possible cure; however, many patients are not candidates for allogeneic transplant due to age, overall health, psychosocial factors, and/or lack of available donors.
Therefore, these patients are unable to receive the therapeutic benefits of the "graft-versus-leukemia" effect of donor immune cells.
The aim of this study is to hopefully break immune tolerance to AML cells to provide better outcomes in patients with non-favorable risk AML.

Detailed Description
Non-favorable risk AML patients will undergo a preparative regimen of lymphodepletion of Flu/Mel followed by autologous transplantation.
Anti-PD-1 therapy of pembrolizumab will begin on Day +1 following stem cell transplantation and will be administered every 3 weeks for a total of 8 doses.
According to the literature, the risk of 2-year relapse is estimated to be 60-80% in patients with non-favorable risk AML in CR-1.
With this protocol, investigators hypothesize that following lymphodepleting chemotherapy and pembrolizumab, the 2-year relapse risk will decrease to less than or equal to 35%.
The one-sided Wald test at 5% significance level will be used to test the hypothesis.
The size of 20 patients yields the power of 90.5% assuming that the actual 2-year leukemia-free survival is 60%.
