Minneapolis-based Celcuity Inc. was like the Rolling Stones at the 2026 American Society of Clinical Oncology annual meeting. The company reported positive phase III data for its pan-PI3K/mTORC1/2 inhibitor gedatolisib, but Celcuity (NASDAQ:CELC) couldn’t get any satisfaction from investors who sent shares down 25.7%, or $31.54, to $91.42 on June 2, 2026.
Eli Lilly and Co.’s end last year to its PI3Kα inhibitor program didn’t mean the pharma player was giving up on the target – far from it, as signaled by the potential $2.5 billion deal signed recently to take over Scorpion Therapeutics Inc. and gain rights to phase I/II-stage STX-478 for breast cancer and other solid tumors. The list of developers at work in the space includes Roche AG plus smaller entities such as Celcuity Inc., Menarini Group, Onkure Therapeutics Inc., Relay Therapeutics Inc. and Totus Medicines Inc.
Joining the dealmaking spree to kick off the 2025 J.P. Morgan Healthcare Conference, Eli Lilly and Co. announced it was picking up an early clinical-stage PI3Kα inhibitor program from Scorpion Therapeutics Inc. in a deal that could be worth up to $2.5 billion, while GSK plc is adding to its cancer pipeline with the acquisition of Idrx Inc. for $1 billion up front.
Bayer AG said it will voluntarily withdraw Aliqopa (copanlisib) from the U.S. market after a confirmatory trial required by the FDA failed to meet the primary endpoint of progression-free survival vs. standard immunochemotherapy in patients with relapsed follicular lymphoma. It marks the latest stumble for PI3K-targeting drugs in the non-Hodgkin’s lymphoma space.
Researchers in Australia have developed new cancer cell line models for pediatric cancers with the lowest survival rates, with a focus on high-risk central nervous system tumors such as glioblastoma.
Convalife Pharmaceuticals Co. Ltd. acquired global rights to develop and commercialize a phosphoinositide 3-kinase (PI3K) β/δ inhibitor from Karus Therapeutics Ltd.

There are 40 years of history behind the development of phosphoinositide 3-kinase (PI3K) inhibitors, Rebecca Dent told her audience at ESMO Breast Cancer 2022. And there have been success stories. There are five FDA-approved PI3K inhibitors in several cancer types, and in April, the FDA approved Vijoice (alpelisib; Novartis AG) for PIK3CA-related overgrowth spectrum, a rare disorder resulting from germline mutations of PIK3CA.

Sponsors developing PI3K inhibitors to treat hematologic malignancies in the U.S. may have to up their game if they want to get FDA approval. The Oncologic Drugs Advisory Committee voted 16-0, with one abstention, that future approvals of the drugs should be supported by randomized data. Given the FDA’s briefing document ahead of the April 21 meeting and its presentations to the committee, the agency is likely to follow that recommendation.
