Today we announced that we’ve entered into a definitive agreement for Terns Pharmaceuticals to be acquired by Merck. This milestone reflects our team’s deep commitment to innovation in oncology and developing high impact medicines, and together we will continue our work towards making a difference for people living with CML.

Terns’ lead program, TERN-701, has a potentially best-in-disease profile that could meaningfully improve upon the efficacy, safety and convenience of existing treatments for chronic myeloid leukemia. Thank you to our team members, the investigators, patients, and community advocates whose dedication and support make the development of TERN-701 possible.

LinkedIn Post by Amy Burroughs, Chief Executive Officer of Terns Pharmaceuticals, Inc. on LinkedIn

I am proud to share the news today that Terns Pharmaceuticals has entered into a definitive agreement to be acquired by Merck.

At Terns, our goal has always been clear — to deliver meaningful therapies for patients with serious unmet needs and to make a lasting impact on human health.

Our mission has also been deeply personal to me. As someone with several friends living with CML and a close family member who passed away from the disease, I understand firsthand the significant burden of CML on people’s lives and the urgent need for better treatment options, particularly for those who must cycle through lifelong treatments due to resistance or tolerance. I am deeply grateful for the patients, site investigators, and our advocacy partners whose resilience, trust and collaboration have inspired our mission at Terns each and every day.

As we look toward our next chapter, I also want to thank our incredible team, whose dedication, curiosity, and unwavering commitment has made our work possible. This milestone strengthens our collective ability to serve patients and builds on the work that brought us here. We are excited for what lies ahead and the impact we can make together.
