Merck to Acquire Peloton Therapeutics, Bolstering Oncology Pipeline

Merck (NYSE: MRK), known as MSD outside the United States and Canada, and Peloton Therapeutics, Inc. today announced that the companies have entered into a definitive agreement under which Merck, through a subsidiary, will acquire privately held Peloton, a clinical-stage biopharmaceutical company focused on the development of novel small molecule therapeutic candidates targeting hypoxia-inducible factor-2α (HIF-2α) for the treatment of patients with cancer and other non-oncology diseases. Peloton’s lead candidate is PT2977, a novel oral HIF-2α inhibitor in late-stage development for renal cell carcinoma (RCC).

“This acquisition exemplifies Merck’s strategy to pursue novel therapeutic candidates based on exceptionally promising and innovative research,” said Dr. Roger M. Perlmutter, president, Merck Research Laboratories. “Peloton scientists have applied their unique expertise in HIF-2α biology to develop PT2977, which has already shown intriguing activity in the treatment of renal cell carcinoma. We look forward to advancing this late-stage asset as part of our broad oncology R&D program.”

Under terms of the agreement, Merck, through a subsidiary, will acquire all outstanding shares of Peloton in exchange for an upfront payment of $1.05 billion in cash. In addition, Peloton shareholders will be eligible to receive a further $1.15 billion contingent upon successful achievement of future regulatory and sales milestones for certain candidates.

“Merck is recognized as a leader in cancer research and shares our commitment to accelerating the development of candidates targeting HIF-2α to help patients with advanced cancers and other diseases,” said John A. Josey, Ph.D., Peloton’s Chief Executive Officer. “We are proud to have advanced PT2977 to this stage of development and believe that Merck is well suited to build upon the progress our company has made.”

The closing will be subject to certain conditions, including the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions. The companies anticipate the acquisition will close in the third quarter of 2019.

Merck was represented by Covington & Burling LLP as legal advisor and Credit Suisse as financial advisor. Peloton was represented by Wilson Sonsini Goodrich & Rosati as legal advisor and Centerview Partners as financial advisor.

About PT2977

PT2977 is a potent, selective, investigational oral HIF-2α inhibitor currently being evaluated in multiple clinical studies. Specifically, PT2977 is being evaluated in a Phase 2 clinical trial in von Hippel-Lindau (VHL) disease-associated RCC, a Phase 2 clinical trial in combination with cabozantinib, a VEGFR-targeting agent, in metastatic RCC, a Phase 1/2 dose-escalation and dose-expansion clinical trial in patients with metastatic RCC, and an expansion arm of its Phase 1/2 clinical trial in glioblastoma multiforme (GBM). In cancer, HIF-2α is aberrantly activated in these diseases as a result of the inactivity of the VHL tumor suppressor. This inactivation of the VHL tumor suppressor is observed in over 90% of clear cell RCC, the most common form of kidney cancer. Results from a Phase 1/2 study of PT2977 demonstrated favorable safety and early signs of anti-tumor activity as a monotherapy for the treatment of patients with advanced or metastatic RCC
