Arvinas (ARVN - Free Report) announced that it has entered into a global collaboration with Pfizer (PFE - Free Report) to co-develop and co-commercialize its investigational breast cancer therapy candidate, ARV-471. Shares increased 8.97% following the announcement, as investors cheered the collaboration given Pfizer’s expertise in the targeted space.

The candidate is an oral PROTAC (PROteolysis TArgeting Chimera) estrogen receptor protein degrader. 

The candidate is currently in a phase II dose expansion study for the treatment of patients with estrogen receptor (ER) positive/human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) locally advanced or metastatic breast cancer.

Shares of Arvinas have declined 0.5% so far this year in comparison with the industry’s 2% decrease.

Per the terms of the agreement, Arvinas will receive an upfront payment of $650 million. It will also be eligible to receive a potential $1.4 billion in milestone payments. Both the companies will equally share worldwide development costs, commercialization expenses and profits. Separately, Pfizer will acquire approximately 7% equity stake in Arvinas for $350 million.

ARV-417 is currently being evaluated in a phase I dose escalation study for metastatic breast cancer, a phase Ib combination study with Pfizer’s Ibrance (palbociclib), and a phase II monotherapy dose expansion study, VERITAC. Interim data from phase I dose escalation study indicated that the drug promoted substantial ER degradation, and exhibited encouraging clinical efficacy and tolerability profile.

Both the companies seek to develop ARV-471 as the potential endocrine therapy of choice for patients and their physicians. Both Arvinas and Pfizer also anticipate starting phase III studies in 2022 across lines of therapy in metastatic breast cancer, including combinations with Ibrance, followed by pivotal studies in the early breast cancer setting.

In 2018, Arvinas announced a separate research collaboration and license agreement with Pfizer for the discovery and development of drug candidates using Arvinas’ proprietary PROTAC technology.

Apart from ARV-471, Arvinas is also developing ARV-110 for the treatment of men with metastatic castrate-resistant prostate cancer.
