NCIt definition : 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.;
