简要总结
The purpose of this study is to evaluate the safety, tolerance and Dose-Limiting Toxicity (DLT) of Recombinant humanized anti-PD-1 monoclonal antibody (JS001) in patients with advanced solid tumors.
详细描述
OVERVIEW
This is a Phase 1, open-label, dose-escalation study of JS-001, a humanized monoclonal IgG4 antibody targeting the Programmed Death -1 (PD-1). It is estimated that 12-24 subjects with advanced or recurrent solid tumors or will be enrolled in the study.
A 3+3 design will be utilized for this Phase 1 study. Four dose levels are planned and include: 0.3, 1, 3, 10 mg/kg/dose. Each of the 4 dose levels will use 2 dose schedules: single dose, repeated doses every 2 weeks. Subjects will be assigned to a dose schedule in the order of study entry.
The study will be the traditional 3 + 3 design with 3 or 6 subjects treated at this dose level and at all subsequent dose levels depending upon the incidence of DLTs. If no DLTs occur in a cohort of 3 subjects, a new cohort of 3 subjects will be treated at the next higher dose level. If 1 of 3 subjects in a cohort experiences a DLT, that cohort will be expanded to 6 subjects. If only 1 of the 6 subjects has a DLT, then the next cohort of 3 subjects will be treated at the next higher dose level. If 2 or more DLTs occur within a cohort, then that dose level will be above the MTD (the highest dose where no more than 1 of 6 subjects has experienced a DLT), and the previous lower (tolerated) dose level will be considered the MTD.
A DLT is defined as a Grade 3 drug-related adverse event occurring within the first cycle (28 days) of dosing (excluding tumor flare defined as local pain, irritation, or rash localized at sites of known or suspected tumor or a transient Grade 3 infusion adverse event) using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 in a single dose cohort.
