简要总结
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and therapeutic activity of GI-108, as a single agent, in patients with advanced or metastatic solid tumors
详细描述
This is an open-label, multicenter, dose escalation and expansion, phase 1/2 study to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and anti-tumor activity of GI-108 as a single agent in advanced or metastatic solid tumors. A control arm is not included.
The study is composed of two phases:
- Dose escalation phase
- Dose expansion phase The dose escalation phase will enroll up to 36 patients with advanced or metastatic solid tumors. At least 3 dose-limiting toxicity (DLT) evaluable patients will be enrolled in each cohort during the dose escalation to establish a maximum tolerated dose (MTD) or tentative recommended phase 2 dose (RP2D). Enrollment in each cohort may be extended to enroll additional 4~7 patients (aiming to recruit upto 10 patients including DLT evaluable patients per cohort), potentially enriched in certain tumor types and/or characteristics to confirm safety, PK and/or pharmacodynamics (PD) of GI-108. The Safety Monitoring Committee (SMC) will determine extension of each cohort based on the review of all available clinical data including efficacy, safety, PK and/or PD. Of the 4 planned cohorts in the dose escalation phase, up to 3 cohorts may be extended to include additional patients based on safety, efficacy PK and/or PD data. The evidence of enrollment extension should be documented for each cohort during dose escalation phase.
