简要总结
This is a multi-center, open label, repeat dose, Phase 1 study consisting of a Dose Escalation Phase and a Dose Expansion Phase to evaluate safety, pharmacokinetics, and clinical activity.
详细描述
The purpose of the Dose Escalation Phase is to examine the safety and determine the maximum tolerated dose of CGX1321 when administered to subjects with advanced GI tumors that have relapsed or are refractory to or not considered medically suitable to receive standard of care treatment.
Once the dose is identified in the Dose Escalation Phase, the Dose Expansion Phase will start. The purpose of the Dose Expansion Phase is to continue to examine the safety and confirm the final Phase 2 dose of CGX1321 when administered to subjects with advanced GI tumors who meet the entry criteria.

研究组 & 干预措施
CGX1321 Dosing
Dose Escalation Phase: Ascending doses of CGX1321 will be administered by cohort to determine the maximum tolerated dose. Patients will receive CGX1321, once daily, orally, for 3 weeks (21 days) followed by a one week (7 day) washout period in each 28 day cycle, according to the cohort they are assigned.
Dose Expansion Phase: Patients will receive the recommended dose (identified in the Dose Expansion Phase) of CGX1321
干预措施: CGX1321 (Drug)
