Interferon-A-2B clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Interferon-α Prevents Leukemia Relapse of AML Patients After Transplantation

Start date: May 1, 2017
Phase: N/A
Study type: Interventional

Allogeneic stem cell transplantation (SCT) remains a powerful therapeutic modality for patients with acute myeloid leukemia (AML).The superior clinical outcomes of allogeneic human SCT versus chemotherapy alone as post-remission treatment could be related to the graft-versus-leukemia (GVL) effects of recovered donor T cells. Our previous study investigated both the association of MRD status with transplant outcomes in haplo-SCT and matched sibling donor transplantation(MSDT)， and also possible differences in the transplant outcomes of patients with positive pre-MRD (as determined by MFC) who underwent haplo-SCT versus MSDT. It provided new evidence that unmanipulated haplo-SCT is superior to matched sibling donor transplantation in eradicating pre-transplantation MRD, indicating that unmanipulated haploidentical allografts have stronger GVL effects.As to the AML patients in standard-risk, who have a positive MRD before MSDT, whether these patients should be given any relapse prevention is the question to be answered in this study. Interferon α-2b exerts a relatively strong immunomodulatory effect. It can kill AL cells by regulating T-cell and/or natural killer cell functions.Consequently, interferon α-2b may have potential value for high-risk AL patients after transplantation. The study hypothesis: Using interferon α-2b following hematopoietic stem cell transplantation in patients with standard-risk AML can further reduce relapse rate and improve leukemia-free survival.
