The multi-billion deal, in which Eli Lilly will acquire Scorpion Therapeutics’ STX-478 program, is a shot in the arm for PI3K treatments, which have had a mixed history over the past few years.
Among the FDA’s pending decisions for this quarter are Vertex’s non-opioid pain drug and Sanofi’s RNA interference therapy for hemophilia A and B.
Pfizer, facing increasing pressure from Novartis, is touting a Phase III win for Ibrance as the first clinical evidence supporting the CDK4/6 inhibitor class’ use in patients with a specific type of breast cancer.
BNT327, now in early-phase trials, is part of a class of drugs that could one day challenge Keytruda’s dominance. BioNTech obtained the candidate when it bought Biotheus last month in an acquisition deal that could reach up to $950 million.

The move is a blow to Gilead’s cancer portfolio. Trodelvy, an antibody-drug conjugate granted accelerated approval for bladder cancer in 2021, failed its confirmatory trial earlier this year.
With the regulatory approval for advanced breast cancer, Roche’s inavolisib is a potential challenger to Novartis’ PI3K inhibitor Piqray, which last year generated $505 million in revenue.
The acquisition was featured Monday in Roche’s Pharma Day presentation, which also included projections of more than $3 billion in annual sales from three early-stage obesity and diabetes drugs.
