Breakthrough Advances in CAR-T Cell Therapy Combined with TKI for Malignant Hematologic System Tumors
At this year’s ASH conference, Professor Huang He, the director of the First Affiliated Hospital of Zhejiang University School of Medicine, presented a significant study on CAR-T cell therapy for B-ALL, marking a groundbreaking stride in the treatment of malignant hematologic system tumors.
This study, targeting newly diagnosed adult Ph-positive acute lymphoblastic leukemia, investigated the combined treatment of dasatinib and CAR-T cell therapy as a frontline therapy for initial patients. The integration of CAR-T cell therapy with tyrosine kinase inhibitors (TKI) aimed to enhance treatment effectiveness.
The study revealed promising outcomes: among 18 patients, the complete molecular remission rate after CD19 CAR-T cell therapy reached 72.2%. Among these patients, subsequent treatment with CD22 CAR-T cells achieved a complete molecular remission rate of 76.9%. At a median follow-up of 13.5 months post CAR-T cell therapy, 16 patients maintained complete hematological remission, while 14 patients sustained complete molecular remission without undergoing allogeneic transplantation. Notably, no CRS (cytokine release syndrome) ≥ Grade 3 or ICANS (immune effector cell-associated neurotoxicity syndrome) occurred during CAR-T cell therapy.
Professor Huang He’s team’s groundbreaking research presented at the ASH conference signifies a leap forward in the treatment of blood-related cancers, signaling a more efficient and accessible era. These findings instill hope for refining treatment strategies and potentially making a significant impact in the field of hematologic oncology.
Beyond the groundbreaking progress in CAR-T cell therapy combined with TKI, the team showcased seven oral presentations and 26 poster exhibitions. These studies encompassed fundamental research on blood disorders, leukemia pathogenesis, acute lymphoblastic leukemia, acute myeloid leukemia, lymphoma, myeloma, hematopoietic stem cell transplantation, and cellular immunotherapy, all crucial for enhancing clinical practices.
We eagerly anticipate further groundbreaking strides by Chinese research teams in cancer treatment studies, anticipating the transformative impact of these research findings in the future.
