At the recent ASCO meeting, researchers from the University of Rochester reported preclinical data for on a new small-molecule inhibitor of WAP four-disulfide core domain protein 2 (HE4) – UR-238 – that is being investigated for the treatment of cancer.
Autotaxin (ATX) is an enzyme responsible for the production of lysophosphatidic acid (LPA), which plays a role in the pathogenesis of systemic sclerosis (SSc). Researchers from Mitsubishi Tanabe Pharma Corp. and colleagues have reported on the preclinical evaluation of MT-5562, a novel oral ATX inhibitor, as a therapeutic option for SSc.
