A Phase 1, Dose-escalation Study of [225Ac]-FPI-2068 in Adult Patients With Advanced Solid Tumours
Condition(s) studied
Investigational drug(s) / intervention(s)
FPI-2053: FPI-2053 is a bispecific antibody that targets EGFR and cMET
[111In]-FPI-2107: \[111In\]-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-2068: \[225Ac\]-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.
Study summary
This is a first-in-human, Phase 1, non-randomized, multicenter, open-label clinical study designed to investigate the safety, tolerability, dosimetry, biodistribution, and pharmacokinetics (PK) of \[225Ac\]-FPI-2068, \[111In\]-FPI-2107, and FPI-2053 in metastatic and/or recurrent solid tumors (HNSCC, NSCLC, mCRC, PDAC, GC, RCC).
Eligibility
Primary outcome measure(s)
- Evaluate safety and tolerability of [111In]-FPI-2107, FPI-2053, and [225Ac]-FPI-2068 — From informed consent up to approximately 5 years post last administration
Frequency, duration, and severity of AEs, DLTs, and changes in clinical, laboratory, and ECG parameters compared to baseline - Determine radiation dose of [111In]-FPI-2107 and [225Ac]-FPI-2068 to whole body, organs, and selected regions of interest. — Within 56 days of administration
Changes in uptake of \[111In\]-FPI-2107 and projected RAD of \[225Ac\]-FPI-2068 by imaging following the administration of varying doses of FPI-2053 - Determine the RP2D of [225Ac]-FPI-2068, given with or without FPI-2053 — 56 days post administration
Estimates of residence time and absorbed radiation doses to the whole body, organs, and selected regions of interest for \[111In\]-FPI-2107 and \[225Ac\]-FPI-2068. - Determine the effect of predose administration of varying doses of FPI-2053 on the radiation dosimetry of [111In]-FPI-2107 and [225Ac]-FPI-2068 to whole body, organs, and selected regions of interest. — 56 days post-administration
Changes in uptake of \[111In\]-FPI- 2107 and projected RAD of \[225Ac\]-FPI-2068 by imaging following the administration of varying doses of FPI-2053
