Pralsetinib is an orally bioavailable selective inhibitor of mutant forms of and fusion products involving the proto-oncogene receptor tyrosine kinase RET, with potential antineoplastic activity. Upon administration, pralsetinib binds to and targets various RET mutants and RET-containing fusion product. RET gene mutations and translocations result in the upregulation and/or activation of RET tyrosine kinase activity in various cancer cell types; dysregulation of RET activity plays a key role in the development and regression of these cancers.
Pralsetinib is a Kinase Inhibitor. The mechanism of action of pralsetinib is as a Rearranged during Transfection (RET) Inhibitor.
