A Phase I Study to Evaluate the Safety, Pharmacokinetics and Efficacy of SY-5007 in Patients With Advanced Solid Tumors
Study Details
Study Description
Brief Summary
This is a phase I, open-label, single-arm, first-in-human study designed to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity of SY-5007 administered orally to participants with advanced solid tumors, including RET-fusion positive NSCLC or RET-mutant medullary thyroid cancer (MTC) or other RET- altered advanced solid tumor.

Phase 1 |
Detailed Description
The study consists of 2 parts, a dose-escalation part and an expansion part. Both parts will enroll patients with RET-fusion positive NSCLC or RET-mutant MTC or other RET- altered advanced solid tumor. Dose-escalation study phase is designed to determine the DLTs (Dose-limiting toxicity) and recommended phase II dose (RP2D) and to characterize the safety, tolerability, and pharmacokinetics (PK) profile of SY-5007. Dose-expansion study phase is designed to evaluate the antitumor activity of SY-5007 in patients.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Dose-escalation and Dose-expansion SY-5007 will be given orally in ascending doses (escalation cohort), until the DLT or RP2D is reached. Up to 7-17 patients will then be enrolled in the expansion cohort at the recommended doses. |
