Summary · why it matters

Biohaven and SK Biopharmaceuticals have announced a global licensing agreement for opakalim, Biohaven's lead epilepsy candidate, in a deal worth up to $795 million plus royalties. Under the agreement, SK Biopharmaceuticals obtains exclusive worldwide rights to Biohaven's Kv7 ion channel platform, while Biohaven receives $400 million in near-term cash, including $350 million at closing and $50 million in 2027. The deal also includes up to $150 million in development and regulatory milestones, with tiered royalties on US net sales ranging from the mid-teens to low twenties. SK Biopharmaceuticals will assume Kv7 program costs, including certain Knopp Biosciences obligations worth up to $245 million plus mid-single-digit royalties. The agreement follows positive proof-of-concept data in epilepsy, where opakalim extended the median time to a second seizure to 141 days versus 47 days on placebo, and 54% of patients in an open-label extension study saw at least a 50% reduction in seizure frequency. Biohaven's CEO stated the deal demonstrates the company's ability to monetize its pipeline through partnerships, providing non-dilutive cash to fund other programs such as BHV-1300 and BHV-1400. The pivotal RISE3 trial results are expected in the second half of 2026.

Novartis Acquires Full Rights to Sironax Brain Delivery Platform

Novartis agreed to acquire full rights to Sironax's proprietary brain delivery platform for neurological disease treatments. The deal gives Novartis control of Sironax's technology designed to transport therapeutics across the blood brain barrier, expanding its toolkit for research into central nervous system disorders where treatment options remain limited. Novartis is a large pharmaceuticals group with a CHF218.8 billion market cap that researches, develops, manufactures, distributes, markets, and sells medicines globally, so gaining access to differentiated delivery technology directly links into its existing focus on complex neurological treatments. The Sironax platform speaks to the same advanced-therapy thesis that underpins Cosentyx's CHMP progress and remibrutinib's Phase 3 data, as Novartis seeks to own hard-to-reach biology where rivals like Roche and Biogen also compete for neurologists' attention. The flip side is that every new modality adds complexity, and recent trial setbacks such as pelacarsen and del-desiran keep development risk front and center, with analysts flagging that stacking capital-intensive projects on top of share buybacks could stretch the balance sheet of a business already carrying a high level of debt.

AbbVie Unveils New VRAYLAR Real-World and Pediatric Safety Data at Psych Congress 2026

AbbVie shared new real-world and pediatric safety data for VRAYLAR in major depressive disorder and bipolar I at Psych Congress 2026. The findings covered routine clinical practice settings, including patients with complex comorbidities and underserved groups, while the pediatric data added information on safety and use in younger patients with mood disorders. AbbVie, a research-focused biopharmaceutical group with a US$466.6b market cap, positions VRAYLAR within a broad portfolio targeting chronic conditions including complex psychiatric disorders. The company said the next concrete checkpoint will be how these data feed into prescribing and label use over the next year, particularly uptake of newly approved low dose VRAYLAR in pediatric and adjunctive MDD settings, trackable in reported prescription trends and segment sales through 2027.

Teva Study Finds Providers Prioritize Drowsiness Risk When Choosing Tardive Dyskinesia Treatment for Older Patients

Teva Pharmaceuticals announced new data showing that healthcare providers prioritize drowsiness risk, the duration of available long-term response data and drug-drug interaction profile when selecting a VMAT2 inhibitor for tardive dyskinesia in patients aged 55 and older. In a discrete choice experiment, 489 healthcare providers ranked somnolence risk, accounting for 26.8% to 36.2% of decision-making weight, and short-term symptom improvement, at 24.4% to 29.5%, as their top priorities, followed by dose formulation at 16.7% to 20.2% and drug-drug interaction risk at 14.4% to 17.3%. Applying those preferences across four patient profiles, AUSTEDO, also known as deutetrabenazine, had the highest predicted choice probability, driven mainly by somnolence risk, duration of long-term response data and drug-drug interaction. The findings were presented at Psych Congress, held September 15 to 19, 2026, in New Orleans. A separate interim analysis from the IMPACT-TD Registry found that among patients with probable tardive dyskinesia who remained untreated with any VMAT2 inhibitor for 24 months, roughly 89% to 96% experienced at least a mild global impact and 60% to 74% experienced moderate-to-severe impact, while 55% to 69% reported stable or worsening severity with no evidence of spontaneous resolution.
