Interventions

NameTypeDescription
FPI-2053DRUGFPI-2053 is a bispecific antibody that targets EGFR and cMET
[111In]-FPI-2107DRUG\[111In\]-FPI-2107 is an imaging agent in which indium-111 is conjugated to FPI-2053. Participants will have a fixed dose of \[111In\]-FPI-2107 followed by imaging scans (with or without pre-administration of FPI-2053).
[225Ac]-FPI-2068DRUG\[225Ac\]-FPI-2068 is a radiopharmaceutical therapy in which an alpha emitter, actinium-225, is conjugated to FPI-2053. Participants will be dosed through IV administration every 56 days for up to 3 cycles of the Treatment Period.
