Palobiofarma signs licensing agreement to develop novel adenosine-based immuno-oncology treatments

On October 21, 2015 Palobiofarma reported that they have entered into a licensing agreement with Novartis (Press release, Palobiofarma, OCT 21, 2015, View Source [SID:1234507780]). Under the terms of the agreement Novartis will acquire exclusive global rights to develop, manufacture and commercialize Palobiofarma´s adenosine A2A receptor antagonist PBF-509, currently entering Phase I clinical trials in Non-Small Cell Lung Cancer. Additionally, Novartis will get access to several adenosine-related patents from Palobiofarma related to the role of adenosine in immunotherapy. Tumour cells have developed 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 in the tumour microenvironment. Palobiofarma will receive an upfront payment of $15 million USD and is eligible to receive near-term clinical, development and commercial milestones on successful projects as well up to double-digit tiered royalties on net sales.
