Disappointing phase II antitumor results with a drug that is designed to preserve the bone marrow during chemotherapy have dashed G1 Therapeutics Inc.’s hopes of expanding Cosela’s label to include metastatic colorectal cancer patients, at least for now. Cosela (trilaciclib) is an intravenous-administered transient CDK4/6 inhibitor designed to mitigate the side effects patients experience with current cytotoxic drug regimens used to treat aggressive cancers by offering myeloprotection and by preserving immune system function, so enabling patients to receive chemotherapy for longer and at higher doses.
Cytokinetics Inc. has patented ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 1 (CD38) inhibitors reported to be useful for the treatment of cancer, obesity and cardiovascular, inflammatory, metabolic, muscle, neurological and renal disorders, among others.
Medshine Discovery Inc. has synthesized dual N-(2-aminophenyl)benzamide compounds acting as lysine-specific histone demethylase 1A (LSD1) and histone deacetylase 1 (HDAC1) inhibitors reported to be useful for the treatment of cancer.
Hookipa Pharma Inc. has achieved a US$10 million milestone payment under its collaboration agreement with Roche (F. Hoffmann-La Roche Ltd.) to develop HB-700, a novel arenaviral immunotherapy for KRAS-mutated cancers.
Legochem Biosciences Inc. has entered into a license agreement with Elthera AG to develop and commercialize a novel antibody-drug conjugate (ADC) therapy using a monoclonal antibody developed by Elthera.
Hillstream Biopharma Inc. has announced initial results evaluating the synergy of ferroptosis inducer HSB-1216 (quatramer salinomycin) with anti-PD-1 antibody pembrolizumab in the Calu-1 KRAS G12C-mutated non-small-cell lung cancer (NSCLC) cell line.
Researchers from The Salk Institute have described a signaling pathway that sets off an unusual, autophagy-dependent cell death mechanism as a fail-safe for cells that have evaded senescence mechanisms. The scientists found a tumor suppression mechanism mediated by telomere signaling, which activated an innate immune response through mitochondrial and telomere complexes to eliminate cells with shortened telomeres.
Leveraging ferroptosis, or iron-mediated cell death, Hillstream Biopharma Inc. has turned up intriguing early stage data in non-small-cell lung cancer (NSCLC) when the company’s candidate called HSB-1216 was paired with the anti-PD-1 antibody Keytruda (pembrolizumab, Merck & Co. Inc.).
