A $500 Million Deal to Reactivate T-cells’ Anti-cancer Response

10/08/2015 - 2 minutes

Heptares Therapeutics, the GPCR-targeted drug company, and British pharma giant AstraZeneca entered a new collaboration under which AstraZeneca will acquire exclusive global rights on the adenosine A2A receptor antagonist, HTL-1071, a small molecule immuno-oncology candidate.

Tumour cells have evolved mechanisms to evade the immune system, including through the production of a natural molecule called adenosine. By stimulating A2A receptors, adenosine stops T-cells within the immune system from proliferating and reduces their ability to destroy cancer cells. Blocking A2A receptors can therefore promote the anti-cancer response of T-cells within the tumour microenvironment.

Under the terms of the agreement, Heptares will grant AstraZeneca an exclusive license to research, develop, manufacture and commercialise HTL-1071. The companies will also collaborate to discover further A2A receptor-blocking compounds for development in cancer immunotherapy.

Heptares will receive an upfront payment of $10 million (€9m) and is eligible to receive additional, significant near term milestone payments based on agreed pre-clinical and/or clinical events. Subject to successful completion of development and commercialisation milestones, Heptares is also eligible to receive more than $500 million (€457m),
