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.
At the 2026 American Society of Clinical Oncology annual meeting, multiple companies presented data for their drugs targeting WEE1, a checkpoint for the transition from G2 into mitosis. Aprea Therapeutics Inc. presented phase 1 data for its WEE1 inhibitor APR-1051 in patients with advanced solid tumors showing two patients with endometrial cancers achieved partial responses in the dose-escalation study. Likewise, Zentalis Pharmaceuticals Inc. had tantalizing early results from a phase Ib study showing azenosertib plus paclitaxel in patients with platinum-resistant ovarian cancer produced an overall response rate of 39% with a median progression-free survival of 7.3 months.
At the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, Revolution Medicines Inc. followed up its stellar top-line data with the details from the phase III RASolute 302 study of its pan-RAS inhibitor daraxonrasib in patients with previously treated, metastatic pancreatic ductal adenocarcinoma. The results were simultaneously published in The New England Journal of Medicine.
New data from Grail Inc.’s randomized study of its Galleri multicancer early detection test could not alter the fact that the U.K. trial missed the primary endpoint of reducing the number of cancers diagnosed at stage III and stage IV. But the company is now suggesting that discounting the initial screen, when most late stage cancers were detected, would be more representative of a real-life steady state screening program.
Multiple companies are chasing Akeso Inc. and Summit Therapeutics Inc. in the battle to potentially dethrone Keytruda (pembrolizumab, Merck & Co. Inc.) as the top cancer immunotherapy for patients with non-small-cell lung cancer with bispecific antibodies targeting PD-(L)1 and VEGF.
Bristol Myers Squibb Co. disclosed in March 2026 that the phase III portion of the seamless phase II/III Successor-2 study testing mezigdomide in combination with carfilzomib and dexamethasone (MeziKd) in patients with relapsed or refractory multiple myeloma was successful. Nearly three months later, the magnitude of success for its Pomalyst (pomalidomide) successor is clear.
Multiple updates on TROP2-directed antibody-drug conjugates (ADCs) for lung and breast cancers highlight both progress made and opportunities for improvement for the targeted class of cancer therapeutics.
