Innate Pharma: First Patient Dosed in IPH6101/SAR443579 Phase 1/2 Clinical Trial in Various Blood Cancers
December 16, 2021- Partner Sanofi advances IPH6101/ SAR443579, a novel NKp46/CD16-based, CD123 targeted NK cell engager, to first-in-human clinical trial in relapsed/refractory AML, B-ALL or HR-MDS
- First molecule from Innate’s multi-specific NK cell engager platform, ANKETTM, to progress to the clinic
MARSEILLE, France–(BUSINESS WIRE)–Regulatory News:
Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) (“Innate” or the “Company”) today announced that the first patient was dosed in a Phase 1/2 clinical trial (NCT05086315), evaluating IPH6101/SAR443579, the first NKp46/CD16-based NK cell engager, in patients with relapsed or refractory acute myeloid leukemia (R/R AML), B-cell acute lymphoblastic leukemia (B-ALL) or high risk-myelodysplastic syndrome (HR-MDS).
The purpose of the dose escalation and dose expansion study, which is sponsored by Sanofi, is to evaluate the safety, pharmacokinetics, pharmacodynamics and initial clinical activity of IPH6101/SAR443579, Innate’s lead ANKETTM asset, in various CD123-expressing hematological malignancies.
This trial is supported by positive pre-clinical results presented at the Society for Immunotherapy of Cancer (SITC) 2021 Congress, which demonstrated the CD123-targeted molecule’s potent antitumor activity against AML, including evidence supporting greater anti-leukemia activity compared with an anti-CD123 antibody. IPH6101/SAR443579 had sustained pharmacodynamic effects in non-human primates, combining efficient depletion of CD123-expressing cells with minor systemic cytokine release in comparison to T-cell engagers. As expected, it also had a favorable safety profile.
“We’re pleased with the initiation of the clinical trial for IPH6101/SAR443579, which is the first ANKETTM asset to enter the clinic. ANKETTM is our new multi-specific NK cell engager platform, which has the potential to engage NK cells through NKp46 and CD16, and more broadly, generate an entirely new class of molecules to induce synthetic immunity against cancer,” said Joyson Karakunnel, MD, MSc, FACP, Chief Medical Officer of Innate Pharma. “We look forward to continuing to advance this platform given the critical role NK cells play in the cancer immunity cycle.”
The start of the trial has triggered a milestone payment from Sanofi to Innate, which is part of a previously announced research collaboration with Sanofi. Under the agreement, the companies collaborate on the generation and evaluation of up to two bispecific ANKETs, using technology from Innate and Sanofi’s proprietary bispecific antibody formats as well as tumor targets. The companies are currently working on the second research program under the agreement.

About ANKETTM:
ANKETTM (Antibody-based NK cell Engager Therapeutics) is Innate’s proprietary platform for developing next-generation, multi-specific natural killer (NK) cell engagers to treat certain types of cancer. The Company’s latest innovation, its tetra-specific ANKETTM molecule, is the first NK cell engager technology to engage two NK cell activating receptors (NKp46 and CD16), a tumor antigen and the interleukin-2 receptor (by an IL-2 variant, IL-2v), via a single molecule. This molecule leverages the advantages of harnessing NK cell effector functions against cancer cells and also provides proliferation and activation signals targeted to NK cells.
In pre-clinical studies, Innate’s tri-1 and tetra-specific ANKETTM technologies promote potent NK cell activation, cytotoxicity and efficient control of tumor growth in pre-clinical models. This versatile fit-for-purpose technology is creating an entirely new class of molecules to induce synthetic immunity against cancer.
About IPH6101/SAR443579:
In the first research program of the Sanofi collaboration, IPH6101/SAR443579, the first NKp46/CD16-based NK cell engager using Innate’s proprietary multi-specific antibody format, has shown antitumor activity in pre-clinical models, including supportive pharmacokinetic/pharmacodynamic (PK/PD) and safety data in non-human primate studies leading to its selection as a drug candidate for development.
About the Innate-Sanofi agreement:
The Company has a research collaboration and licensing agreement with Sanofi to apply Innate’s proprietary technology to the development of innovative multi-specific antibody formats engaging NK cells through the activating receptors NKp46 and CD16 to kill tumor cells.
Under the terms of the license agreement, Sanofi will be responsible for the development, manufacturing and commercialization of products resulting from the research collaboration. Innate Pharma will be eligible to up to €400m in development and commercial milestone payments as well as royalties on net sales.
