A Phase 3, Multicenter Trial for Pediatric Philadelphia Chromosome-positive B-Acute Lymphoblastic Leukemia -2025 Project
In Brief
A Phase 3 clinical trial evaluating olverembatinib for Acute Lymphoblastic Leukemia (ALL) Philadelphia Chromosome-positive (Ph+) and Childhood Leukemia, Acute Lymphoblastic. Currently recruiting, targeting 150 participants across 24 sites in 2 countries.
Detailed Summary
This prospective clinical trial evaluates the effectiveness and safety of "chemotherapy-light" regimen incorporating the third-generation TKI olverembatinib, the bi-specific CD3/CD19 T cell engager blinatumomab, and the BCL-2 selective inhibitor venetoclax for newly diagnosed pediatric/adolescent patients with Ph+ ALL. The CCCG-Ph+ B-ALL-2025 protocol will be modified as following compared to the CCCG-ALL-2020 protocol
Study Details
Timeline
Interventions
All Ph+-ALL patients will uniformly use the 3rd generation of TKI olverembatinib (OVB) instead of dasatinib throughout the regimen. OVB is combined with Vincristine and Prednisone (VP) during the first 2 weeks and with blinatumomab during the last 4 weeks of remission induction in this protocol. Patients will receive blinatumomab for 28 days as induction instead of CAT to improve induction response and avoid toxicity. All patients will receive two cycles of HDMTX+Blina-14 and 4 times of triple intrathecal therapy (TIT) throughout the consolidation 1 phase. To decrease the toxicities of high-dose AraC, the dosage will be reduced to 1 g/m2 in the consolidation 2 phase in contrast to 2 g/m2 in 2020 protocol. Throughout the early Maintenance Therapy, dexamethasone and vincristine combination will be added with either venetoclax or daunorubicin alternatively for five cycles, given after MTX and 6-MP.
