简要总结
This is a first-in-human Phase 1/2, non-randomized, multi-centre, open-label clinical study designed to investigate safety, tolerability, PK, and preliminary anti-tumour activity of [225Ac]-FPI-1434 (radioimmuno-therapeutic agent) in patients with solid tumours that demonstrate uptake of [111In]-FPI-1547 (radioimmuno-imaging agent), and to establish the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of repeat doses of [225Ac]-FPI-1434 Injection in patients with solid tumours that demonstrate uptake of [111In]-FPI-1547 (radioimmuno-imaging agent).
详细描述
This study consists of a Phase 1 portion and a Phase 2 portion.
Phase 1 includes the following cohorts: Single dose-ascending cohorts and Multi- dose ascending cohorts of [225Ac]-FPI-1434 and Multi- dose ascending cohorts evaluating administration of FPI-1175 (cold antibody), followed by, [225Ac]-FPI-1434 (cold + hot), with cycles repeating every 42 days. And Cold Antibody Sub-study evaluating administration of ascending doses of FPI-1175 followed by [111In]-FPI-1547.
The Phase 2 will evaluate [111In]-FPI-1547 and [225Ac]-FPI-1434 with or without FPI-1175 in tumour-specific cohorts. The decision to utilize FPI-1175 in the Phase 2 portion of the study will be determined based on Phase 1 data, including safety, tolerability, pharmacokinetic and dosimetry results.
