Action mechanism:

monoclonal antibody/immune checkpoint inhibitor.

IPH2201 (anti-NKG2A) is a first-in-class humanized IgG4 antibody. NKG2A is a checkpoint receptor that inhibits anti-cancer functions of cytotoxic NK and T lymphocytes. NKG2A recognises HLA-E ligands, and by expressing HLA-E cancer cells can protect themselves from killing by CD94/NKG2A-positive NK-, NKT-, and T-cells (a/b and g/d). HLA-E is frequently up-regulated on cancer cells and this occurs in patients with different types of solid tumours or haematological malignancies. In some types of cancers, high-levels of HLA-E appear to confer poorer prognosis. IPH2201 blocks the inhibitory function of CD94/NKG2A, thereby unleashing NK and T cells to kill cancer cells, despite expression of HLA-E. IPH2201 enhances NK and T cell killing of a variety of cancer cell types. Hence, IPH2201 may potentially re-establish a broad anti-tumour response mediated by NK and T cells. Anti-NKG2A mAb may also enhance the cytotoxic potential of other therapeutic antibodies. In an ongoing single- and multiple-dose Phase I dose-escalation safety trial in patients with rheumatoid arthritis, IPH2201 appears to have a safe and well-tolerated profile at all doses tested.

MEDI4736 is a human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). Signals from PD-L1 help tumours avoid detection by the immune system. MEDI4736 blocks these signals, countering the tumour’s immune-evading tactics.This antibody is directed against B7-H1, have been shown to block the interaction between B7-H1 and its receptors, PD-1 and CD80 (B7-1). This blockade may help to overcome the immunosuppressive effects of B7-H1 on anti-tumor T cells.

Details:

* On April 24, 2015, AstraZeneca and MedImmune, the Company’s global biologics research and development arm, announced that they have entered into a collaboration to accelerate and broaden the development of Innate Pharma ’s proprietary anti-NKG2A antibody, IPH2201, including in combination with MEDI4736, an anti-PD-L1 immune checkpoint inhibitor developed by MedImmune. Currently in Phase II development, IPH2201 is a potential first-in-class humanised IgG4 antibody. NKG2A is a checkpoint receptor that inhibits the anti-cancer functions of Natural Killer (NK) and cytotoxic T-cells.

The initial development plan includes: Phase II combination clinical trials with MEDI4736 in solid tumours; multiple Phase II trials planned by Innate to study IPH2201 both as monotherapy and in combination with currently approved treatments across a range of cancers; and the development of associated biomarkers. The combination of IPH2201 with MEDI4736 adds to the broad programme of immuno-oncology combination trials that AstraZeneca and MedImmune have planned and underway. The studies aim to address multiple immune pathways, harnessing AstraZeneca’s own extensive pipeline and working in partnership to explore the significant potential of immunotherapies in transforming the way cancer patients are treated. The transaction is subject to customary terms and conditions, including the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act, and is expected to become effective in the second quarter of 2015.

 

Financial terms:

Under the terms of the agreements, AstraZeneca will make an initial payment to Innate of $250 million, which includes the consideration for exclusive global rights to co-develop and commercialise IPH2201 in combination with MEDI4736, as well as access to IPH2201 in monotherapy and other combinations in certain treatment areas. AstraZeneca will pay a further $100 million prior to initiation of Phase III development, as well as additional regulatory and sales-related milestones. AstraZeneca will book all sales and will pay Innate double-digit royalties on net sales. The arrangement includes the right for Innate to co-promote in Europe for a 50% profit share in the territory.

Latest news:

* On July 7, 2015,  Innate Pharma  announced that the co-development and commercialization agreement with AstraZeneca on IPH2201, received HSR clearance. The companies will now begin to work together to accelerate and broaden the development of IPH2201, including in combination with MEDI4736, an anti-PD-L1 immune checkpoint inhibitor developed by MedImmune. On June 30, 2015, Innate Pharma received the initial payment of $250 million from AstraZeneca.
