With age, senescent cells become detrimental to tissues. Mayo Clinic scientists have observed this phenomenon in the lung alveoli, where senescent macrophages accumulated in aging tissue and in early stages of non-small-cell lung cancer (NSCLC) driven by the Kras oncogene. “We found that the macrophages were present in the earliest stages of the disease. Strategies targeting these cells for elimination or preventing their accumulation would be worthwhile to test in other conditions (assuming we find they occur),” Darren Baker, a Mayo Clinic senescent cell biologist and senior author of the study, told BioWorld.
Immutep Ltd. announced an AU$80 million (US$52.1 million) capital raise that consists of a AU$50 million placement and a AU$30 million entitlement offer to eligible shareholders to fund clinical programs for lead candidate eftilagimod (IMP-321, efti), a lymphocyte activation gene-3 (LAG-3) fusion protein and major histocompatibility complex class II agonist that stimulates both innate and adaptive immunity for treating cancer.
In a deal potentially worth $392 million, C4 Therapeutics Inc. signed with Betta Pharmaceuticals Co. Ltd. to develop and market an orally bioavailable BiDAC degrader for non-small-cell lung cancer (NSCLC).
Providing no details, Mirati Therapeutics Inc. failed to meet its overall survival primary endpoint in the phase III Sapphire trial with sitravatinib. The receptor tyrosine kinase inhibitor was tested in combination with anti-PD-1 checkpoint inhibitor Opdivo (nivolumab, Bristol Myers Squibb Co.) vs. docetaxel in patients with second- or third-line advanced nonsquamous non-small-cell lung cancer. According to Mirati, this patient population consists of about 70,000 people in the U.S. and Europe who have derived prior benefit from a PD-(L)1 inhibitor.
Researchers from Kanaph Therapeutics Inc. have reported the discovery and preclinical evaluation of a small-molecule EGFR inhibitor, KNP-501, being developed as an anticancer agent.
Notching another deal in its efforts to extend the global reach of toripalimab, Junshi Biosciences Co. Ltd. granted Dr. Reddy’s Laboratories Ltd. rights to develop and commercialize the PD-1 inhibitor in a regional licensing agreement that could be worth as much as $728.3 million.
Researchers from TYK Medicines Inc. have reported the discovery and preclinical evaluation of TY-1091, a second-generation RET inhibitor being developed for the treatment of RET-mutant cancers.
Notching another deal in its efforts to extend the global reach of toripalimab, Junshi Biosciences Co. Ltd. granted Dr. Reddy’s Laboratories Ltd. rights to develop and commercialize the PD-1 inhibitor in a regional licensing agreement that could be worth as much as $728.3 million.
