About ANKET®

ANKET® (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.

This versatile, fit-for-purpose technology is creating an entirely new class of molecules to induce synthetic immunity against cancer.

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 2016 research collaboration and licensing agreement, Sanofi is responsible for the development, manufacturing and commercialization of products resulting from the research collaboration, which includes IPH6101/SAR’579 (CD123 NK Cell Engager) and IPH6401/SAR’514 (BCMA NK Cell Engager). Innate Pharma will be eligible to up to €400m in development and commercial milestone payments as well as royalties on net sales.

Under the terms of a new license agreement entered in December 2022, which includes IPH62 (B7-H3 NK Cell Engager) and 2 options, Innate received €25m upfront payment and is eligible for up to €1.35bn total in preclinical, clinical, regulatory and commercial milestones plus royalties on potential net sales. Upon candidate selection, Sanofi will be responsible for all development, manufacturing and commercialization

About Monalizumab:

Monalizumab is a potentially first-in-class immune checkpoint inhibitor targeting NKG2A receptors expressed on tumor infiltrating cytotoxic CD8+ T cells and NK cells.

NKG2A is an inhibitory checkpoint receptor for HLA-E. By expressing HLA-E, cancer cells can protect themselves from killing by NKG2A+ immune cells. HLA-E is frequently overexpressed in the cancer cells of many solid tumors and hematological malignancies. Monalizumab may reestablish a broad anti-tumor response mediated by NK and T cells, and may enhance the cytotoxic potential of other therapeutic antibodies1.

AstraZeneca obtained full oncology rights to monalizumab in October 2018 through a co-development and commercialization agreement initiated in 2015. The ongoing development for monalizumab is focused on investigating monalizumab in various combination strategies in different malignancies.

About the Innate-AstraZeneca monalizumab agreement:

In October 2018, AstraZeneca obtained full oncology rights to monalizumab by exercising its option under the co-development and commercialization agreement initiated in 2015.

The financial terms of the agreement include potential cash payments up to $1.275 billion to Innate Pharma. Including the $50 million payment triggered by dosing the first patient in the Phase 3 PACIFIC-9 clinical trial, Innate Pharma has received $450 million to date.

For any commercialized oncology indication, AstraZeneca will book all sales revenue and will pay Innate low double-digit to mid-teen percentage royalties on net sales worldwide except in Europe where Innate Pharma will receive 50% share of the profits and losses in the territory. Innate will co-fund 30% of the costs of the Phase 3 development program of monalizumab with a pre-agreed limitation of Innate’s financial commitment.
