Popis: TPS3163 Background: FF-10832 (832) is a liposomal formulation of gemcitabine (GEM) that demonstrates a prolonged half-life and preferential uptake in tumor vs normal tissues and marrow in pre-clinical models. Macrophage uptake has been shown in the tumor microenvironment (TME), with subsequent GEM release in tumor cells. This relative selectivity and anti-tumor immunological changes observed in the TME may lead to decreased toxicity and increased efficacy compared to GEM. Ferumoxytol (FMX) may be a surrogate for nanoparticle penetration into tissue and is being examined as a potential correlate for activity. Methods: This ongoing Phase 1, 3+3 dose-escalation study of 832 will determine the safety profile, maximum tolerated dose, dose-limiting toxicities (DLT) and recommended Phase 2 dose, and will be followed by expansion. Enrollment of up to 60 patients (pts) with advanced solid tumors is planned. Pre-treatment (tx) FMX MRI scans are performed, followed by 832 administration on Days 1 &15 of each 28-day cycle until disease progression or unacceptable toxicity. In addition to standard biomarker and imaging evaluations, change in macrophage polarity, myeloid-derived suppressor cell (MDSC) and regulatory T cell populations are being investigatedin peripheral blood and tumor tissue. Clinical trial information: NCT03440450.
