Researchers from Ospedale San Raffaele presented the preclinical characterization of SR-1891, a long-acting capsid assembly modulator (CAM) in models of chronic hepatitis B. In Hepa D38 cells, the compound exhibited EC50 and EC90 values of 0.2 and 0.8 nM, respectively, without any detectable cytotoxicity.
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.
Alterations in PNPLA3, particularly the I148M variant, impair lipid metabolism in hepatocytes, leading to lipid accumulation and driving progression from steatosis to fibrosis and cirrhosis. Targeting this genetic driver may offer a strategy to reduce steatosis and limit disease progression.
Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by lipid accumulation in the liver and inflammation. Sterol O-acyltransferase 2 (SOAT2) is a key enzyme in intestinal absorption and hepatic secretion of cholesterol. PRD Therapeutics Inc. has developed PRD-001, a selective SOAT2 inhibitor currently in phase I trials for MASH.
Several presentations at EASL highlight a new generation of therapies coming into view, with the work from Tune Therapeutics Inc. standing out as one of the most relevant for the novelty it represents and the step forward it signals. The company is investigating the use of TUNE-401 as a potential treatment for hepatitis B.
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.
In the treatment of hepatocellular carcinoma (HCC), the long-term benefits of second-line tyrosine kinase inhibitors such as sorafenib are often limited by resistance mechanisms and adverse effects. The deubiquitinase ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1) is upregulated in advanced HCC disease and has been linked to poor prognosis and treatment resistance.
