U3-1402/patritumab-GGFG-DXd is the first HER3-targeting antibody-drug conjugate (ADC) showing clinical efficacy in non-small-cell lung cancer. However, an elevated proportion of patients with this cancer express low levels of HER3 and are nonresponsive to this ADC. In addition, novel ADCs are needed to treat other cancer types, including colorectal cancer.
Although preclinical studies of genetically engineered interleukin-18 (IL-18) historically indicated its potential in cancer treatment, interest in the cytokine languished after GSK plc shelved its IL-18 therapeutic on lack of responses in a phase II melanoma trial. But in 2020, Yale University-based professor of immunobiology Aaron Ring set about reviving IL-18 as a cancer therapeutic. He went on to engineer a decoy-resistant form of IL-18 and then founded Simcha Therapeutics Inc. to develop the drug – named ST-067.
Merck KGaA has entered deals that could bring U.K. artificial intelligence companies Benevolentai Ltd. and Exscientia plc more than $1.2 billion. Oxford, U.K.-based Exscientia and Merck will collaborate to find three small-molecule candidates in oncology, neuroinflammation and immunology. Exscientia is getting $20 million up front and could bring in $674 million in milestones payments.
Peptidream Inc. and Genentech Inc., a Roche Holding company, signed a deal worth up to $1 billion to discover and develop macrocyclic peptide-radioisotope (peptide-RI) drug conjugates. Peptidream, of Kawasaki, Japan, will use its peptide discovery platform system technology to discover, optimize and develop macrocyclic peptide candidates for use as peptide-RI drug conjugates against targets of interest to Genentech. Genentech will pay Peptidream an up-front payment of $40 million and up to $1 billion in potential development, regulatory, and commercial-based milestones. In addition, Peptidream is eligible to receive tiered royalties on net sales (ex-Japan) of any products arising from the collaboration.
Satyarx Pharma Innovations Pvt Ltd. has disclosed novel bicyclic compounds acting as DNA repair protein RAD51 homolog 1 inhibitors reported to be useful for the treatment of cancer.
The discovery of new 68Ga-labeled CD38-targeted peptides for PET imaging was recently discussed by researchers from Peking University First Hospital and China National Center For Nanoscience & Technology.
Benevolentai Ltd. has signed a strategic collaboration with Merck KGaA to identify novel drug candidates, initially for three targets in oncology, neurology and immunology.
Rohitukine is a chromone alkaloid with antiproliferative, anti-inflammatory, and immunomodulatory activities. Although several rohitukine derivatives are being investigated as potent anticancer leads, the potential antitumor activity of the naturally occurring rohitukine-N-oxide has yet to be evaluated.
Long bones, vertebrae and skull bones have distinct types of stem cells, and new insights into those stem cells could lead to new ways to treat both rare developmental disorders of skull formation and the all-too-common phenomenon of bone metastases. Scientifically, the work, which was published in two papers by Matthew Greenblatt and colleagues in Nature, adds to the increasing understanding of bone’s complexities. “Bone may serve as an endocrine organ that is secreting factors throughout the body,” Greenblatt said.
Magnet Biomedicine Inc. emerged from stealth mode and pulled down a $50 million series A round co-led by founding investor Newpath Partners alongside Arch Venture Partners. The firm is advancing molecular glue discovery by way of rational selection and design, looking past known protein-protein interactions and what Magnet calls “tangential” degradation approaches to analyze the broader protein landscape and ultimately pair targets with rationally chosen presenters in the tissue where the disease manifests.
