Spots Global Cancer Trial Database for Safety of AM-928 Infusion in Advanced Solid Tumors

Study Description

Brief Summary: This is a Phase I, open-label, dose-escalation study for a novel cancer treatment, AM-928, intravenous infusion antibody for advanced solid tumor. The study is aimed to learn the safety, tolerability, pharmacokinetics, and preliminary efficacy profile of AM-928. The dose escalation strategy will adopt accelerated titration combined with a Bayesian optimal interval (BOIN) design. Seven dose levels are designed and each participant will be assigned to a specific dose regimen depending on the time of enrollment. In the study, each participant will receive AM-928 treatment cycles till meeting any treatment discontinuation criterion and be followed for safety and long-term survival. The whole study is expected to take approximately three years to complete.

Detailed Description: This is a first-in-human Phase I, open-label, dose-escalation study to investigate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of AM-928 infusion in subjects with advanced solid tumors in multiple sites in Taiwan. Eligible subjects will be dosed with different dosages of AM-928 in 1 of the 7 dose levels (0.1, 0.3, 1, 3, 6, 10, 15 mg/kg). Dose levels will be escalated from dose Level 1 at 0.3 mg/kg to Level 6 at 15 mg/kg of AM-928 (or may be de-escalated to Level -1 at 0.1 mg/kg), which will be administered (intravenous infusion) once weekly (QW) for 4 weeks (D1, D8, D15, D22) as a treatment cycle until any treatment discontinuation criterion is met. Basically, there will be no breaks between dosing cycles. From Cycle 4, intra-subject dose escalation may be applied if supported by preliminary safety and PK data. The dose escalation strategy will adopt accelerated titration combined with a Bayesian optimal interval (BOIN) design. The accelerated titration will be adopted for 0.3 mg/kg, while the BOIN design will be adopted for other dose levels, including 1 mg/kg, 3 mg/kg, 6 mg/kg, 10 mg/kg, and 15 mg/kg. In the "accelerated titration" stage, if any ≥ Grade 2 adverse event occurs, the current and subsequent dose groups will be changed to the BOIN dose escalation method. The target toxicity rate for the maximum tolerated dose (MTD) is ϕ= 0.3, and the maximum sample size is determined to be 30, maximum of 9 subjects per dose level. A cohort size of 3 and a maximum cohort number of 3 for each dose level will be adopted for subject recruitment. The dose escalation may end when one of the following criteria is met: (1) The planned sample size of 30 has been reached; (2) 9 subjects have been treated and evaluable for DLT at the next intended dose level (should not exceed 9 subjects at one dose level); (3) all doses explored appear to be overly toxic, and the MTD cannot be determined.
