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.

Two phase III failures with Roche Holding AG subsidiary Genentech Inc.’s gantenerumab in staving off mild cognitive impairment tied to Alzheimer’s disease (AD) revealed the level of amyloid-beta removal was lower than the company expected. The protein amyloid beta accumulates in the brains of AD patients and its removal is suspected to be an eventual boon to AD patients. But there are still plenty of doubts. Top-line results from Genentech’s phase III Graduate I and II studies show gantenerumab, a fully human monoclonal IgG1 antibody, missed the primary endpoints of slowing clinical decline in those with mild cognitive impairment due to AD and mild AD dementia.

Researchers at the Walter and Eliza Hall Institute of Medical Research (WEHI) in Melbourne, Australia, have developed a new genome editing technique than can activate any gene, including those that have been silenced, allowing new drug targets and causes of drug resistance to be explored.

Genentech Inc. presented data on structure-based lead optimization of orally bioavailable hematopoietic progenitor kinase 1 (HPK1) inhibitors. HPK1 is a negative regulator of T-cell receptor signaling in human T cells and target inhibition significantly increases cytokine production, such as IFN-gamma, TNF-alpha and IL-2, and T-cell proliferation, suggesting HPK1 inhibition as an intracellular T-cell target for cancer immunotherapy.

A subsidiary of Jiangxi Jemincare Group Co. Ltd. has out-licensed global rights to its androgen receptor degrader JMKX-002992 to Roche Holding AG and its subsidiary Genentech Inc. in a deal worth up to $650 million.
