The candidate is currently being evaluated in a phase I/II study for treating certain patients with chronic myeloid leukemia (CML).Per the company, TERN-701 has shown promising results so far, with encouraging major and deep molecular response rates by week 24 in clinical studies. Based on this early data, management believes that, if successfully developed, TERN-701 could offer a differentiated treatment option for certain patients with CML.TERN-701 has received an Orphan Drug designation from the FDA for treating CML.The acquisition is expected to be closed in the second quarter of 2026, subject to customary closing conditions. It is likely to further strengthen and diversify MRK’s oncology pipeline.The deal is expected to lead to a charge of around $5.8 billion, or roughly $2.35 per share, which will be reflected in Merck’s second-quarter and full-year 2026 GAAP and non-GAAP results.MRK Eyes M&A Deal to Offset Keytruda’s Upcoming LOEMerck has been on an acquisition spree in recent times, as it faces looming patent expiration of its blockbuster drug, PD-L1 inhibitor Keytruda, in 2028. Keytruda accounts for more than 50% of the company’s pharmaceutical sales.Merck acquired Cidara Therapeutics for $9.2 billion in January 2026. The acquisition added CDTX’s lead pipeline candidate, CD388, a first-in-class long-acting, strain-agnostic antiviral agent, currently being evaluated in late-stage studies for the prevention of seasonal influenza in individuals at higher risk of complications.Last year, Merck acquired Verona Pharma for around $10 billion, which added the latter’s lead drug Ohtuvayre, a novel, first-in-class maintenance treatment for chronic obstructive pulmonary disease, with multibillion-dollar commercial potential. Ohtuvayre's commercial launch is off to a solid start, backed by strong growth in new patient starts and total patients treated.Merck believes new products like Ohtuvayre could drive long-term growth and help offset the revenue gap expected from Keytruda’s upcoming loss of exclusivity in 2028.
