Merck Acquires OncoEthix, a Privately Held Oncology Company Developing Novel BET Inhibitors for Hematological and Solid Cancers

Merck (MSD), has acquired, through a subsidiary, OncoEthix, a Swiss-based privately held biotechnology company specializing in oncology drug development.

Through the acquisition, Merck has gained an investigational, novel oral BET (bromodomain) inhibitor, OTX015, which is currently in Phase 1b studies for the treatment of hematological malignancies and advanced solid tumorus.

“Oncology is a priority area of focus for Merck and the acquisition of OncoEthix supports our strategy to prioritize the development of innovative molecules with the potential to improve the treatment of advanced cancers,” said Dr Roy Baynes, senior vice president, global clinical development, Merck Research Laboratories. “The potential first-in-class oral BET inhibitor, OTX015, has demonstrated early promising activity in hematological cancers and strategically complements our broad immuno-oncology development programme.”

“We are delighted that OTX015 will now be in the hands of Merck, a company with a successful track record of developing cutting-edge therapies,” said Bertrand Damour, chief executive officer, OncoEthix. “The acquisition underlines the promise that OTX015 has shown in the treatment of hematological malignancies, and the potential it has for the treatment of advanced solid tumours. We are confident that our transaction with Merck best positions OTX015 to be developed to its full potential in areas of high unmet medical need.”

BET proteins are considered potential therapeutic targets in cancer, as they play a pivotal role in regulating the transcription of key regulators of cancer cell growth and survival, including c-Myc. Interim data from ongoing Phase I clinical studies of OTX015 have demonstrated meaningful clinical activity in patients with hematological malignancies. Interim data were recently presented at the American Association of Cancer Research (AACR) Annual Meeting in April 2014. An international, open-label Phase I study evaluating OTX015 in five different solid tumours was initiated in November 2014.

Financial terms of the acquisition include an upfront payment of up to $110 million to OncoEthix. Additional milestone payments of up to $265 million are contingent upon certain clinical and regulatory events being achieved.
