BACKGROUND: The nucleoside FF-10502-01, structurally similar to but with different biologic effects than gemcitabine, shows promising activity both alone and combined with cisplatin in preclinical gemcitabine-resistant tumor models. We conducted an open-label, single-arm, 3 + 3 first-in-human trial to explore the safety, tolerability, and antitumor activity of FF-10502-01 in patients with solid tumors.
METHODS: Patients with inoperable metastatic tumors refractory to standard therapies were enrolled. Escalating intravenous FF-10502-01 doses (8-135 mg/m2 ) were administered weekly for 3 weeks in 28-day cycles until progressive disease or unacceptable toxicity was observed. Three expansion cohorts were subsequently evaluated.
RESULTS: A phase 2 dose of 90 mg/m2 was determined after evaluating 40 patients. Dose-limiting toxicities included hypotension and nausea. Phase 2a enrolled patients with cholangiocarcinoma (36), gallbladder cancer (10), and pancreatic/other tumors (20). Common adverse events were grade 1-2 rash, pruritus, fever, and fatigue. Grade 3 or 4 hematologic toxicities were observed at low incidences, including thrombocytopenia (5.1%) and neutropenia (2%). Confirmed partial responses (PRs) occurred in five patients with gemcitabine-refractory tumors, including three with cholangiocarcinoma and one each with gallbladder and urothelial cancer. Median progression-free and overall survival rates in patients with cholangiocarcinoma were 24.7 and 39.1 weeks, respectively. Prolonged progression-free survival in patients with cholangiocarcinoma was associated with BAP1 and PBRM1 mutations.
CONCLUSION: FF-10502-01 was well tolerated with manageable side effects and limited hematologic toxicity. Durable PRs and disease stabilizations were observed in heavily pretreated biliary tract patients who had received prior gemcitabine. FF-10502-01 is distinct from gemcitabine and may represent an effective therapy.
