Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - [225]-FPI-2059
Treatment: Drugs - [111In]-FPI-2058

Experimental: Phase 1 Dose Escalation -

Experimental: Phase 1 Dose Expansion -


Treatment: Drugs: [225]-FPI-2059
\[225Ac\]-FPI-2059 is a targeted alpha therapeutic that consists of an NTSR1-targeting small molecule that is linked to Ac-225, an alpha particle emitting radionuclide. Participants will be dosed through IV administration every 56 days up to four cycles. The dose depends on cohort assignment.

In the Dose Expansion arm, \[225Ac\]-FPI-2059 will be administered at the RP2D as determined in Phase 1 Dose Escalation.

Treatment: Drugs: [111In]-FPI-2058
\[111In\]-FPI-2058 is an imaging agent that consists of an NTSR1-targeting small molecule linked to In-111.Participants will receive \[111In\]-FPI-2058 by IV Injection for imaging once during screening period. The dose is consistent across cohorts.

* Measurable disease per RECIST v.1.1
* Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
* Sufficient target expression in at least one measurable lesion as determined by imaging following injection of [111In]-FPI-2058
* Adequate organ function
* Tumor tissue (either archival within the last 24 months or fresh biopsy)
