Innate Pharma Announces New Clinical Data for Lacutamab and SAR443579/IPH6101 at ASH 2023
November 3, 2023- Positive results from the TELLOMAK Phase 2 Trial with lacutamab in heavily pretreated patients with relapsed and refractory Sézary syndrome selected for oral presentation
- Preliminary monotherapy lacutamab Phase 1b clinical data and pre-clinical combinability data in patients with peripheral T-cell lymphoma
- Presentation on SAR443579 / IPH6101, a potential first-in-class NKp46/CD16-based NK cell engager targeting CD123; SAR443579 / IPH6101 is ANKET® platform lead asset and under development by partner Sanofi, which demonstrated clinical remissions
MARSEILLE, France–(BUSINESS WIRE)–Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) (“Innate” or the “Company”) today announced that several abstracts, including one oral presentation, have been selected for the 65th ASH (American Society of Hematology) Annual Meeting and Exposition, taking place December 9-12, 2023 in San Diego, California.
Lacutamab in patients with T-cell Lymphomas
- Abstract details from the TELLOMAK Phase 2 Trial in Patients with Advanced Sézary syndrome include:
The oral presentation will highlight the results from Cohort 1, designed to evaluate safety and efficacy of single agent lacutamab in 56 patients with relapsed/refractory Sézary syndrome after at least two prior systemic therapies including mogamulizumab. At the data cut-off of May 1, 2023, with a global confirmed Objective Response Rate (ORR) of 37.5% (n=21; 95% CI 26.0-50.6) including 2 Complete Responses (CRs), confirmed ORR in skin of 46.4% (n=26; 95% CI 34.0-59.3) including 5 CRs and confirmed ORR in blood of 48.2% (n=27; 95% CI 35.7-61.0) including 15 CRs, data confirm that lacutamab monotherapy shows promising clinical activity in a heavily pre-treated relapsed/refractory population previously treated with a median of 6 prior lines (range 2-15), including mogamulizumab, and an overall favorable safety profile. Clinical Benefit Rate (CBR, defined as CR+PR+SD) was 87.5 % (n=49; 95% CI 76.4-93.8). Median PFS was 8.0 months (95% CI 4.7, 21.2). Continued evaluation of this promising new targeted treatment option for patients with Sezary Syndrome is warranted.
- Preliminary Monotherapy Clinical Data and Pre-Clinical Combinability Data in Patients with Peripheral T-Cell Lymphoma (PTCL):
The poster will display preclinical combination data supporting anti-tumor activity and rationale for the exploration of lacutamab in combination with approved and novel therapies in patients with PTCL. Preliminary monotherapy data from an ongoing Phase 1b study in PTCL is also presented.
SAR443579/IPH6101 in patients with relapsed or refractory acute myeloid leukemia (R/R AML), B-cell acute lymphoblastic leukemia (B-ALL) or high-risk myelodysplasia (HR-MDS) (from a Joint Research Collaboration with Sanofi)
A presentation from the Sanofi oncology pipeline at ASH includes updated efficacy and safety results from an open-label, first-in-human, dose-escalation study of an investigational CD123 targeting Natural Killer Cell Engager (NKCE). Results investigating SAR443579 as a monotherapy for the treatment of blood cancers with high unmet needs, including relapsed or refractory acute myeloid leukemia, B-cell acute lymphoblastic leukemia and high-risk myelodysplasia show data across all dose levels tested. Observed clinical remissions will also be presented. Abstract details include:
As of July 5, 2023, 43 patients (42 R/R AML and 1 HR-MDS) across 8 Dose Levels (DLs) at 10 – 6000 μg/kg/dose were included. Patients had received a median of 2.0 (1.0 – 10.0) prior lines of treatment with 13 patients (30.2%) reporting prior hematopoiectic stell cell transplantation and 36 patients (83.7%) with prior exposure to venetoclax. In DLs with a highest dose of 1000 μg/kg QW, 5/15 (33.3%) patients achieved a CR (4 CR / 1 CRi) as of the cut-off date. Data from PK/PD and in vitro mechanistic analyses studying dose-response relations will also be presented. SAR443579 was well tolerated up to doses of 6000 μg/kg QW with observed clinical benefit in patients with R/R AML. The results are consistent with the predicted favorable safety profile.
