The Nasdaq Biotechnology Index (NBI) declined 1.12 percent in December, slipping from 5,772.06 to 5,707.20. The SPDR S&P Biotech ETF (XBI) was largely flat, edging up 0.07 percent from 121.85 to 121.93.

In December, US President Donald Trump and nine major drugmakers — including Bristol Myers Squibb, Gilead Sciences, Merck, Genentech, Novartis, Amgen, Boehringer Ingelheim, Sanofi and GSK — announced agreements to lower
prescription drug prices for the Medicaid
program and for cash-paying patients under a
most-favored-nation (MFN) pricing framework. These announcements built on
earlier MFN pricing agreements the administration had signed with Pfizer and AstraZeneca.During 2025, several big drugmakers
announced new US investments to avert the looming threat of import tariffs. In
all, drugmakers pledged over US$ 370 billion in the US in
2025.In
December, the US also
finalized a trade agreement with the UK,
eliminating US tariffs on British pharmaceutical products and medical technology for at least three years in return for
Britain spending more on medicines and overhauling how it values drugs. Access the Pipeline Prospector Dashboard for December 2025 Newsmakers (Free Excel) FDA approves pill version of Novo’s Wegovy, GSK’s treatment for eosinophilic asthma okayedRegulatory approvals remained a major

Amicus Therapeutics in an all-cash
transaction valued at approximately US$ 4.8 billion, marking the largest deal in BioMarin’s 28-year history. The acquisition adds two approved and fast-growing rare disease therapies — Galafold (migalastat) for Fabry disease

in Alabama for its GLP-1 drug; Ultragenyx faces phase 3 setbackThe year 2025 was a good year for Eli Lilly — it inked nearly 30 deals through the year and became the first healthcare company in the world to
reach a market capitalization of US$ 1 trillion in November. Lilly
closed the year by pledging over US$ 6 billion towards building a
new API manufacturing facility in
Huntsville, Alabama. The plant will produce small-molecule and
peptide medicines, including orforglipron, Lilly’s oral GLP-1 weight-loss drug. Earlier in the year, Lilly had committed US$ 27 billion towards expanding US
manufacturing capacity. After failing to bag an FDA approval for its rare disease gene therapy in July, Ultragenyx Pharmaceutical faced yet another setback in
December when a late-stage trial of its experimental drug setrusumab failed to meet its primary endpoint in children and
young adults with osteogenesis imperfecta (brittle bone disease). The trials
were conducted in partnership with Mereo BioPharma. Ultragenyx’s stock was down 33 percent in December.There was some good news for patients
suffering from Duchenne muscular dystrophy (DMD). Capricor Therapeutics reported positive phase 3 results for its DMD cell therapy — deramiocel. This success comes after Sarepta’s gene
therapy Elevidys (delandistrogene moxeparvovec-rokl) suffered a setback in June, following patient deaths. Access the Pipeline Prospector Dashboard for December 2025 Newsmakers (Free Excel) Our viewThe pharmaceutical industry is growing at
a healthy rate, and is expected to attain a size of US$ 1.19 trillion in 2026 (up from US$ 1.16 trillion in 2025). The industry is also expected to witness innovations, especially in fields such as weight management, rare diseases and oncology.However,
we do expect some tug-of-war on drug prices. According to a Reuters
report, drugmakers plan to raise US prices on at least 350 branded medications including some vaccines, even as the US administration pressures them for price cuts.On the geopolitical front, 2026 began with the US military capturing Venezuelan president Nicolás Maduro. Such developments can add to the volatility and uncertainties in the market, impacting supply chains, energy prices and investor sentiments.
