Gowling WLG's Life Sciences team has advised Amphista Therapeutics on two multi-million pound deals to advance the company's work developing protein degrading therapeutics for treating a wide range of diseases.

The latest deal is a strategic collaboration and license agreement with Bristol Myers Squibb to discover and develop small molecule protein degraders. Under the agreement, Bristol Myers Squibb will gain a global exclusive license to the resulting degraders and further development and commercialisation rights. Amphista will receive $30 million upfront, the potential for up to $1.25 billion in milestone payments and payment for a limited expansion of the collaboration, plus royalties on global net product sales.

The deal closely follows an agreement with Merck Healthcare to collaborate in developing novel protein degrading therapeutics in indications in oncology and immunology. This will see Amphista receive an upfront payment, R&D funding and success-based milestone payments of up to €893.5 million ($1.0 billion), as well as royalties. Both deals are subject to regulatory clearances or approvals.

Gowling WLG's head of life sciences in the UK, Patrick Duxbury, led the team involved, alongside legal director Mathilda Davidson. Partner Samuel Beighton advised on regulatory matters related to the two transactions.  They worked closely with Amphista's chief business officer, Beverley Carr, on both deals.

Patrick Duxbury said: "The combination of these two arrangements will significantly advance Amphista's work to date in the field of targeted protein degradation. We are glad to have played a part in supporting the company's strategic priorities by helping drive both deals forward to successful execution."
