Although ovarian cancers appear to be immunologically active, they do not respond well to immunotherapy in the clinic. In a study published on Dec. 14, 2022, in Nature, a multidisciplinary team at Memorial Sloan Kettering Cancer Center (MSK) led by Sohrab Shah and Dmitriy Zamarin has uncovered several mechanisms of immune evasion that can help explain why ovarian cancers have been resistant to immunotherapy to date.
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.
Sciclone Pharmaceuticals Holdings Ltd. has obtained marketing approval in China for Danyelza (naxitamab) for patients with relapsed or refractory high-risk neuroblastoma. The drug, in combination with granulocyte macrophage colony-stimulating factor, was approved to treat pediatric patients aged 1 and above, as well as adults, who have relapsed or refractory high-risk neuroblastoma in the bone or bone marrow and have demonstrated a partial or minor response to prior therapy or stable disease.
Anocca AB raised €25 million (US$26.5 million) in venture debt financing from the European Investment Bank to maintain its progress toward the clinic. “We’re quickly moving towards regulatory filings next year,” CEO and co-founder Reagan Jarvis told BioWorld. The company aims to start its first clinical trial in 2024.
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.
