  Crenolanib

Description of Crenolanib: Crenolanib is an orally bioavailable small molecule, targeting the platelet-derived growth factor receptor (PDGFR), with potential antineoplastic activity. Crenolanib binds to and inhibits PDGFR, which may result in the inhibition of PDGFR-related signal transduction pathways, and, so, the inhibition of tumor angiogenesis and tumor cell proliferation. PDGFR, up-regulated in many tumor cell types, is a receptor tyrosine kinase essential to cell migration and the development of the microvasculature. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)

Crenolanib is an investigational new drug being developed by AROG Pharmaceuticals, LLC for the treatment of certain types of cancer. Crenolanib is a tyrosine kinase inhibitor that acts by specifically inhibiting the receptor tyrosine kinases PDGFRA and PDGFRB. Crenolanib is an orally bioavailable, selective small molecule inhibitor of the Platelet-derived growth factor receptor PDGFR) tyrosine kinase, inhibiting both PDGFRA and PDGFRB at picomolar concentrations.  Type III receptor tyrosine kinases (RTK), including c-KIT, PDGFRα and PDGFRβ, have been directly implicated in the pathogenesis of epithelial, mesenchymal, and hematological malignancies.[1] The PDGF/PDGFR pathway is the primary driver of oncogenesis in several malignancies including gastrointestinal stromal tumor (GIST),[2] both adult[3] and pediatric gliomas,[4] as well as a subset of Non-small-cell lung carcinoma (NSCLC).[5] These malignancies often respond to treatment with non-selective inhibitors of PDGFR like imatinib and sunitinib. Crenolanib is a 100-500-fold more potent inhibitor of PDGFRα and PDGFRβ than other commercially available TKIs. It is currently being developed as an antineoplastic agent in cancers.
