Brief Summary

ETP-ALL is a recently recognized high-risk subgroup and the optimal therapeutic approaches are poorly characterized. Based on the pediatric-inspired, PEG-L-asparaginase-intensified and MRD-directed PDT-ALL-2016 protocol, this open-label, one-arm, multi-site trial is aimed to evaluate the safety and effect of a novel oral histone deacetylase inhibitor chidamide for adult ETP-ALL/LBL in CHINA.

Detailed Description

Early T-cell precursor (ETP) lymphoblastic leukemia (ETP-ALL) is a neoplasm composed of cells committed to the T-cell lineage but with an unique immunophenotype indicating only limited early T differentiation. In the highly orchestrated development of T cell fate specification under physiological condition, the most immature early thymic progenitors (ETPs) retain multilineage potentials. ETP-ALL blasts have a characteristic immunophenotype, with reduced/absent expression of T-lymphoid markers CD1a, CD5, CD8; and positivity for at least one HSC and/or myeloid antigen CD34, CD117, HLA-DR, CD13, CD33, CD11b, CD65. Recent study shed light on the genetic landscape of adult ETP-ALL, which revealed that more than 40% adult ETP-ALL harbored histone modification mutations. Chidamide is a novel oral HDACi with promising activity in non-Hodgkin lymphoma (NHL). Based on the pediatric-inspired, PEG-L-asparaginase-intensified and MRD-directed PDT-ALL-2016 protocol, this open-label, one-arm, multi-site trial is aimed to evaluate the safety and effect of a novel oral histone deacetylase inhibitor chidamide for adult ETP-ALL/LBL. HDACi chidamide at a dose of 10mg/day will be added to ETP-ALL group from induction therapy to consolidation therapy (total courses of chidamide treatment: 5 courses for allo-HSCT after Consolidation Module-3; 12 courses for patients non-allo-HSCT after Consolidation Module 1-9). Primary study endpoint of PDT-ETP-ALL is event-free survival of ETP-ALL group and secondary study endpoints are complete remission and MRD after induction, adverse event and overall survival of ETP-ALL group.
