Might FAB just turn out to be the AIM recovery story of the last few years?19 Sep 2025 09:07

Big week for Fusion Antibodies (AIM: FAB). After almost two years validating OptiMAL® with the US National Cancer Institute (NCI), they’ve now said they want to keep using it for years to come – and are negotiating terms. In short: the platform is proven, and now it’s about price.
The company describe OptiMAL® as a world-first patented mammalian display antibody library designed to speed up drug discovery. If commercialised, it could shift Fusion’s revenues from one-off projects to high-margin, repeatable income and royalties. Even a sliver of success – think of Humira’s $20bn+ peak annual sales – would be transformational. Fusion’s past work on Caly-002, later sold in a deal worth c.$400m, shows the kind of upside their science can feed into.
Readouts from Investors at this week’s sessions said management were glowing with excitement about what’s ahead, and it’s no surprise – securing NCI, the global leader in cancer research, would be a huge endorsement and likely pull in pharma/biotech clients. With the formal OptiMAL® launch at the world’s top antibody conference in the US in December this year, timing couldn’t be better, though as we see with the NCI negotiations already underway, deals could come sooner.
Add in no debt, a cash runway already extended by a growth raise earlier this year, big grants improving margins and management’s confidence they don’t need to raise more equity, and the ingredients for a remarkable recovery from 2023 are there.
Of course, nothing is guaranteed, the market is tough, and everyone should do their own research – but momentum appears to building fast with their premium products coming on board i’d encourage anyone with a pharma interest to take a look.
