Innate Pharma Shares Updated Results From the Sanofi Developed Blood Cancer Phase 1/2 SAR443579/IPH6101 Trial
-
SAR443579 /IPH6101, ANKET® platform lead asset, is a first-in-class NKp46/CD16-based NK cell engager targeting CD123 from a joint research collaboration betweenInnate Pharma and Sanofi, under development by Sanofi in R/R AML, B-ALL and HR-MDS
-
SAR443579 /IPH6101 continues to show clinical benefit and durable responses along with a favorable safety profile in patients with R/R AML, with 5 complete remissions (4 CR / 1 CRi) achieved at 1 mg/kg, with durable CR (>10 months) observed in 3 patients
The study, led by Sanofi, tests SAR’579 as a monotherapy for the treatment of blood cancers with high unmet needs, including relapsed or refractory acute myeloid leukemia (R/R AML), B‑cell acute lymphoblastic leukemia (B-ALL) and high-risk myelodysplasia (HR-MDS). SAR’579 has FDA Fast Track Designation for the treatment of acute myeloid leukemia.
“We are pleased to see that SAR’579 continues to show promising and durable clinical efficacy along with a favorable safety profile. The ongoing Phase 1/2 study has recently progressed to the Phase 2 stage, marking a significant milestone in its development. We look forward to the continued progress of this multi-specific NK Cell Engager which holds great potential to benefit patients suffering from various blood cancers,” says Dr
Fifty-nine patients (58 R/R AML and 1 HR-MDS) across 11 dose levels (0.01 – 6mg/kg) were treated. Patients had received a median of 2 (1 – 10) prior lines of treatment. A maximum response rate was observed at a final target dose of 1 mg/kg every week with 5 AML patients achieving a CR (4 CR/1 CRi)1. The median treatment duration was 7.9 weeks, with durable CR (>10 months) observed in 3 patients with 2 remaining on maintenance therapy as of the data cutoff. SAR’579 was well tolerated up to doses of 6 mg/kg every week. These data will form the basis for selection of recommended doses for development in the Phase 2 portion of the trial.
“We are excited about the emerging results from our development of SAR’579. Ongoing studies are focused on further demonstrating the potential of the NK cell engager in patients with leukemia. We look forward to sharing data from these trials at future scientific meetings,” says
