Pharmacology
Cemiplimab-rwlc is a recombinant human IgG4 monoclonal antibody (PD-1 inhibitor) that binds to PD-1 and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response.
Selpercatinib is a kinase inhibitor that selectively inhibits wild-type RET and multiple mutated RET isoforms (including gene fusions and activating point mutations) as well as VEGFR1 and VEGFR3, and at clinically achievable concentrations also inhibits FGFR1, 2, and 3, blocking constitutive RET signaling that acts as an oncogenic driver promoting tumor cell proliferation.
