Repeat expansions of two or more base pairs cause dozens of neurological disorders – Huntington’s disease, which is caused by an expansion of the triplet CAG in the coding sequence for huntingtin, is perhaps the most famous one. Now, investigators at Stanford University have shown that cancer genomes, too, frequently feature repeat expansions.
While new data from Arcus Biosciences Inc. and Gilead Sciences Inc. didn't do much to calm an unsteady development corridor, researcher, developers and analysts still hold out hope for the TIGIT pathway. The Arcus-Gilead randomized phase II study combining anti-TIGIT domvanalimab and anti-PD1 antibodies for treating first-line, metastatic non-small-cell lung cancer produced positive results, including improvements in median progression-free survival (PFS) and six-month landmark PFS rates vs. monotherapy. But a hefty dent in Arcus' shares provide a reminder of TIGIT’s fragility as a field, and a reminder of the phase III failure in May for Roche Holding AG unit Genentech Inc.'s anti-TIGIT immunotherapy tiragolumab, which dragged down the share value of several other class entrants. Arcus stock (NASDAQ:RCUS) dipped deeply on Dec. 20 on the new data’s release, but rallied on Dec. 21 by closing 7.5% upward at $22.15 each.
Astellas Pharma Inc. reported top-line results showing zolbetuximab, a monoclonal antibody targeting Claudin 18.2, met the primary endpoint for progression-free survival as well as secondary endpoints for overall survival in the phase III Glow trial in CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma.
Magenta Therapeutics Inc., the developer of an antibody-drug conjugate intended to help prep certain relapsed/refractory acute myeloid leukemia and myelodysplastic syndrome patients for stem cell transplant or gene therapy, has stopped dosing the drug in part of an ongoing trial after observing two cases of serious adverse events (SAEs) possibly related to the candidate.
After posting positive top-line data in August from its phase III ENHANCE-2 study of ensifentrine for treating chronic obstructive pulmonary disease (COPD), Verona Pharma plc now has positive results from the companion phase III study. The ENHANCE-1 trial of ensifentrine as a COPD maintenance treatment hit its primary and key secondary endpoints, prompting the company to say it plans to submit an NDA for the treatment to the U.S. FDA sometime in the first half of 2023.
Onward Medical NV reported clinical outcomes for the first 10 patients given therapy to regulate blood pressure using its implantable ARC technology. This pulse generator produced an immediate improvement in blood pressure regulation in all study participants.
“Far superior to what almost anyone expected,” was how H.C. Wainwright analyst Ed Arce described the top-line readout for Madrigal Pharmaceuticals Inc.’s phase III study of resmetirom, which hit both of its dual endpoints in patients with nonalcoholic steatohepatitis (NASH) and is expected to form the basis of an accelerated approval application to the U.S. FDA in the first half of 2023.
Cofactor Genomics Inc. opened the non-small-cell lung cancer portion of its study of the Oncoprism test, which predicts response to immunotherapy. The Predicting Immunotherapy Efficacy from Analysis of Pre-treatment Tumor Biopsies (PREDAPT) trial will study the test’s predictive ability in 11 cancers in total.
Guardant Health Inc. reported positive results from the ECLIPSE trial demonstrating 83% sensitivity of its DNA blood test in detecting colorectal cancer (CRC) in average-risk adults. Specificity was 90% in people without advanced neoplasia, as well as in those who had a negative colonoscopy result.
Astellas Pharma Inc. reported top-line results showing zolbetuximab, a monoclonal antibody targeting Claudin 18.2, met the primary endpoint for progression-free survival (PFS) as well as secondary endpoints for overall survival (OS) in the phase III Glow trial in CLDN18.2-positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma.
