Abstract

Aim: To evaluate a novel antisense oligonucleotide drug targeting human IGF-1R in preclinical and phase I studies of liver cancer. Materials & methods: The tolerability and safety of an investigational new drug were evaluated in a dose-escalation trial involving 17 patients with advanced liver cancer after preclinical assessment of pharmacokinetics and pharmacodynamics. Results: The drug exposure levels in the phase I trial were determined by the in vivo efficacy with pharmacokinetics evaluation in rats and rhesus monkeys. This clinical study showed that the maximum tolerated dose was 3.96mg/kg, and the dose-limiting toxicity dose was 4.4mg/kg. Conclusion: The drug was safe and tolerable in patients with advanced liver cancer. Clinical Trial Registration: ChiCTR2100044235 (www.chictr.org.cn).
