About

Clinical Study on the Safety and Effectiveness of low-dose chidamide maintenance therapy after allogeneic hematopoietic stem cell transplantation for T-cell acute lymphoblastic leukemia or T-cell lymphomas.

Full description

This is a phase ll, multi-center, single-arm clinical study.This study is indicated for high-risk of T-cell acute lymphoblastic leukemia or T-cell lymphomas patients. It aims to evaluate the safety and effectiveness of low-dose chidamide maintenance therapy after allogeneic hematopoietic stem cell transplantation for T-cell acute lymphoblastic leukemia or T-cell lymphomas to prevent relapse. 44 patients will be enrolled. The clinical end points include relapse-free survival, acute or chronic GVHD, non-relapse mortality, and overall survival, etc.

Inclusion criteria

T-cell acute lymphoblastic leukemia or T-cell lymphomas (mainly including peripheral T-cell lymphoma, NK/T-cell lymphoma, T-lymphoblastic lymphoma, etc.) must be diagnosed before enrollment. The diagnostic criteria refer to the 2016 WHO classification. Patients is in high-risk group or standard-risk group with MRD-positive patients after transplantation.
Age 14-70;
Stable hematopoietic reconstitution after receiving allogeneic hematopoietic stem cell transplantation, no aGVHD or stable aGVHD control and stable primary disease;
Complete donor chimerism after transplantation;
During the screening period after transplantation (within 4 weeks before Chidanilide administration), the primary disease is remission and MRD is negative.
Eastern Cooperative Oncology Group (ECOG) physical condition score is 0-2 points;
Creatinine clearance ≥ 60 mL/min (according to the Cockcroft-Gault formula);
Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 3 × upper limit of normal range (ULN), total bilirubin ≤ 2 × ULN;
Echocardiography (ECHO) shows left ventricular ejection fraction (LVEF) ≥ 50%
Life expectancy >8 weeks;
Voluntarily sign the informed consent form, understand and comply with the requirements of the research.

Exclusion criteria

Other serious diseases that may limit patients to participate in this trial (such as advanced infection, uncontrolled diabetes, renal failure);
Known human immunodeficiency virus (HIV) infection, or hepatitis B virus that cannot be controlled by drugs (HBV-DNA positive, and HBV DNA test value above the upper limit of normal value) or hepatitis C virus (anti-HCV positive, and HCV viral titer detection value above the upper limit of normal value) Chronic Infect;
