Under the agreement, Ellipses has been granted global rights to develop and commercialise EP0017 and will assume the full cost and responsibility for the remaining pre-clinical and clinical development of the compound. In line with its strategy, Ellipses intends to out licence EP0017 for commercialisation if it proves safe and effective in clinical trials. SunRock will continue to be involved in the development of EP0017 to ensure efficient translational activities through a service agreement with Ellipses. If Ellipses out-licences EP0017, SunRock will also receive milestone payments and royalties.

EP0017 is a first-in-class bifunctional fusion protein with a dual mechanism of action. It selectively targets HER3, which is overexpressed in several different tumour types, and additionally, binds to the tumour death receptors DR4 and DR5, inducing tumour cell death. Promising data has been generated in a range of preclinical models that demonstrate the potential of EP0017.

Laureano Simón, Ph.D., CEO of SunRock Biopharma, said
"The agreement with Ellipses will speed up the development of EP0017, moving this potentially life-changing asset towards the clinic and then hopefully towards cancer patients who desperately need novel approaches to fight invasive tumours."

Rajan Jethwa, MD, CEO of Ellipses Pharma commented:
"Our mission is to rapidly develop innovative cancer therapies, to get these therapies into the clinic as quickly as possible and potentially save more lives. We are excited about the opportunity to progress the development of this promising asset and look forward to working with SunRock to expedite the preclinical work."
