FDA approved IDVYNSO, a once-daily two-drug regimen (doravirine/islatravir) for adults with virologically suppressed HIV-1, intended to replace their current antiretroviral therapy. It is the first non-INSTI, tenofovir-free two-drug therapy to demonstrate non-inferiority to a three-drug regimen in two Phase 3 trials (052 vs BIKTARVY and 051 vs baseline ART). The product will be available in pharmacies after May 11 and carries contraindications with strong CYP3A inducers and with lamivudine or emtricitabine, plus safety considerations including potential severe skin reactions and drug interactions. Trials enrolled 708 participants with diverse demographics, supporting another option in HIV treatment.
Merck reported first clinical data from its PD-1xVEGF bispecific MK-2010 in a Chinese phase 1/2 NSCLC trial, showing unconfirmed ORRs of 55% in treatment-naïve PD-L1-positive patients at 20 mg/kg every three weeks and 44% at 30 mg/kg, with lower responses in previously treated patients. Across backfill cohorts (n=72) the safety profile included dose-limiting toxicities like grade 3 proteinuria and hemoptysis, several bleeding events, and deaths in higher-dose arms, though the maximum tolerated dose has not been reached. Results are early, from small cohorts, and Merck has not disclosed phase 3 plans, as rivals advance multiple PD-(L)1xVEGF programs; more data are needed to define MK-2010's potential role.
An ICIJ investigation shows Merck’s Keytruda has become one of the world’s best-selling drugs not just because of therapeutic value but due to an expansive patent portfolio (more than 1,200 filings in 53 countries), lobbying, and pricing tactics that raise costs for patients worldwide while governments and insurers struggle to fund access; the report details price disparities, secrecy, accelerated approvals, and strategic moves like drug-dosing and product hopping that help Merck extend monopoly into the 2030s, with patients in India, Guatemala, the U.S. and elsewhere paying vast out-of-pocket or facing restricted access.
Merck will acquire Terns Pharmaceuticals for about $6.7 billion in cash ($53 per share), expanding its cancer pipeline ahead of Keytruda’s 2028 patent expiry.

TERN-701 has shown encouraging early activity and carries FDA Orphan Drug Designation from 2024, underscoring its potential as a differentiated CML therapy.
Merck is splitting its human health business into two divisions—a dedicated oncology unit to oversee cancer therapies (including Keytruda) and a separate specialty pharma and infectious diseases unit for non-cancer products and vaccines—part of a strategy to sharpen growth after Keytruda's looming patent cliff.
