GSK stock slips in London as hepatitis B drug details awaited; Feb 4 results loom

London, Jan 9, 2026, 10:50 GMT — Regular session GSK (GSK.L) shares were down 0.6% at 1,879.5 pence by 1050 GMT, trading in a 1,871p to 1,886p range.

GSK said it plans to start global regulatory filings from the first quarter of 2026 and described bepirovirsen as an antisense oligonucleotide, a short strand of

AbbVie stock slides on $1.3 billion charge and outlook cut as deal chatter swirls

New York, Jan 8, 2026, 19:33 EST — After-hours AbbVie shares dropped 4% on Thursday, slipping to $224.13 in after-hours trading from a previous close of $233.41, as investors digested a profit forecast reduction linked to a hefty charge. The move matters because AbbVie is scrambling to make up lost ground after Humira’s patent expired, leaning heavily on acquisitions to sustain its growth. Traders have been quick to pounce on any whispers of another big deal, especially after takeover chatter about cancer-drug developer Revolution Medicines briefly lifted AbbVie shares just a day before.

MoonLake stock jumps after FDA feedback clears path for sonelokimab filing without new HS trials

New York, Jan 8, 2026, 17:06 EST — After-hours MoonLake Immunotherapeutics shares jumped 27% to $14.34 on Thursday after the biotech said U.S. regulators supported a route to file its hidradenitis suppurativa treatment without doing more trials for the skin disease. The stock churned between $11.20 and $17.28, and roughly 24 million shares traded. The update is a big deal because it clears up a near-term unknown: whether MoonLake would need to pay for and run another late-stage study before it can seek approval. For a clinical-stage company with no product revenue, that sort of timing decision can jolt the

New York, Jan 8, 2026, 10:13 EST — Regular session Pfizer Inc shares rose 0.3% to $25.36 on Thursday after a U.S. appeals court blocked a Trump administration pilot that would have changed how safety-net hospitals pay for some medicines. The program covered the first 10 drugs heading into Medicare price negotiations, including Pfizer and Bristol Myers Squibb’s blood thinner Eliquis, and the American Hospital Association said it would have a “devastating effect.” Reuters Why it matters now is less about a single day’s trade and more about the plumbing of drug pricing.

AbbVie stock drops before the bell after Revolution Medicines deal talk gets swatted down

New York, January 8, 2026, 05:14 (EST) — Premarket AbbVie Inc (ABBV) shares slipped 1.6% to about $229.64 in premarket trading on Thursday after the drugmaker denied it was in talks to buy cancer biotech Revolution Medicines and cut its 2025 profit view.

New York, Jan 7, 2026, 20:51 EST — Market closed Regeneron Pharmaceuticals shares climbed 4.6% on Wednesday after Bank of America upgraded the drugmaker to “Buy” from “Underperform” and raised its price objective to $860.
