T Cell Lymphoblastic Lymphoma/Leukemia Relapse Allogeneic Hematopoietic Stem Cell Transplantation

ClinConnect Summary

This clinical trial is studying a new treatment approach for patients with high-risk T-cell lymphoma or leukemia who have had a stem cell transplant. The goal of the study is to see if combining two medications, called demethylating agents and venetoclax, can help prevent the cancer from coming back after the transplant. The trial is currently recruiting participants aged 14 to 55 who have undergone an allogeneic stem cell transplant due to T-cell lymphoma or leukemia and have specific high-risk factors related to their disease.

To be eligible for this trial, patients must have had a transplant and show certain signs that put them at higher risk for relapse, like older age at diagnosis or specific lab results. Participants can expect to receive the new treatment and be monitored closely by the research team for any side effects or improvements in their condition. It's also important to know that some patients may not qualify for the trial if they have ongoing infections or other serious health issues.
