Title:
4090 Phase I Study of TQB3455, a Selective Inhibitor of IDH2 with Favorable Safety and More Potent Efficacy to IDH2-R172K Mutation, for Acute Myeloid Leukemia and Myelodysplastic Syndrome
Published date:
11/03/2022
Excerpt:
Efficacy was analyzed only in patients with AML. Three pts was not evaluable for response due to withdrawal by patients before the first efficacy evaluation. Of the 32 evaluable pts, overall response rate (ORR) was 40.63 %, including 12 pts (37.5%) in complete remission(CR) or CR with incomplete hematologic recovery (CRi), 1 pts (3.13%) in partial remission (PR). TQB3455 shows more powerful inhibitory effects on IDH2-R172K rather than IDH2-R140Q/W mutation (ORR, 66.67% vs 25.00%, p=0.03; CR, 41.67% vs 15.00%, p=0.12). TQB3455 is well-tolerated for myeloid malignancy at the R2PD of 100 mg qd. It also yield high rates of clinical response in pts with mIDH2 AML.
