China’s Center for Drug Evaluation and South Korea’s Ministry of Food and Drug Safety cleared Transcenta Holdings to begin phase III pivotal trials of osemitamab (TST-001) in combination with nivolumab and chemotherapy for first-line treatment of HER2-negative, Claudin 18.2 expressing locally advanced or metastatic gastric or gastroesophageal cancer.
Hillstream Biopharma Inc. has signed an exclusive agreement with Applied Biomedical Science Institute (ABSI) to license technology for human antibodies targeting novel HER2 and HER3 conformational epitopes. The goal is to develop proprietary multiformat biologics, including bispecific antibodies and antibody-drug conjugates (ADCs).
Researchers at Jiangsu Hansoh Pharmaceutical Group Co. Ltd. and Shanghai Hansoh Biomedical Co. Ltd. have disclosed phosphatidylinositol 3-kinase (PI3K) inhibitors reported to be useful for the treatment of cancer and more.
Gastric cancer (GC) is the fourth most common cause of cancer-related deaths, causing more than 750,000 deaths in 2020. Platinum-based 5-fluorouracil (5-FU) combinations improve survival times compared to surgery alone, but emergent treatment resistance limits long-term clinical benefits. Accordingly, there is an urgent need to develop alternative approaches to overcoming chemoresistance.
Breakthroughs in early detection of cancer offer increasing hope for better outcomes and longer lives for individuals affected by malignancies. This year’s American Society of Clinical Oncology annual meeting highlighted strong results from several companies at the forefront of this potential transformation.
Antengene Corp. Ltd.'s Claudin 18.2 antibody-drug conjugate (ADC) ATG-022 has been granted two orphan drug designations consecutively by the FDA for the treatment of gastric cancer and pancreatic cancer.
Gastric cancer persists as the fourth leading cause of cancer-related deaths. Syndecans (SDCs) are a family of four transmembrane heparan sulfate proteoglycans involved in cell proliferation, migration and adhesion, among others, and syndecan-4 (SDC4) expression has been shown to be up-regulated during the early stages of the gastric carcinogenesis.
Claudin 18.2 (CLDN18.2) is involved in the formation of tight junctions and is expressed in normal gastric mucosa, maintaining its expression during malignant transformation of the gastric epithelium. It is also aberrantly expressed in other tumor types, such as esophageal, pancreatic and lung adenocarcinoma, making it an attractive target for cancer immunotherapy.
East China University of Science & Technology has described pteridinone derivatives acting as epidermal growth factor receptor (EGFR; HER1; erbB1) (mutant) inhibitors reported to be useful for the treatment of cancer.
