GSK announced that the US FDA has accepted for priority review a supplemental New Drug Application for gepotidacin as an oral treatment for uncomplicated urogenital gonorrhoea in patients aged 12 years and older (weighing ≥45 kg), with a Prescription Drug User Fee Act action date set for December 2025. The submission is supported by the EAGLE-1 phase III trial published in The Lancet, where oral gepotidacin (two doses of 3,000 mg) achieved a 92.6% success rate at the urogenital site (187/202) versus 91.2% (186/204) for intramuscular ceftriaxone plus oral azithromycin, meeting non-inferiority. No failures from bacterial persistence were reported and no serious drug-related adverse events were observed; the most common adverse reactions were mild to moderate gastrointestinal events. Gepotidacin previously received US approval as Blujepa for uncomplicated urinary tract infection and its development was funded in part by BARDA and the US Department of Defense.

GSK has monetised its licence with CureVac through a settlement linked to CureVac’s 7 Aug 2025 agreement with BioNTech. The company will receive an immediate $370 million payment ($320 m cash) and collect a 1 % royalty on all 2025-onward US sales of Pfizer/BioNTech influenza, COVID-19 and combination mRNA vaccines.
The settlement also amends the CureVac licence, materially reducing future royalties that GSK would owe on its own mRNA pipeline products.
- Contingent upside: if BioNTech’s proposed acquisition of CureVac closes, GSK gains an extra $130 m cash, a further 1 % royalty on ex-US sales of the same vaccines and lower milestone obligations.
- Accounting: the $370 m is booked as other operating income (adjusting item) in Q3-2025; future royalties flow through total & core results.
- Litigation: GSK’s separate patent suits against Pfizer/BioNTech continue in the US and Europe.
- Strategic: GSK will tender its ≈16.6 m CureVac shares under the forthcoming offer.
The deal delivers near-term cash, creates recurring high-margin royalty streams and lowers eventual COGS for GSK’s own mRNA vaccines, though additional proceeds depend on the CureVac acquisition closing and legal uncertainties persist.
