About

This is a Phase 1, open-label, multicenter, dose escalation and expansion study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of the experimental drug(SYHX2001) in previously treated patients with advanced or metastatic cancer.

Full description

This is a multicenter, open-label, dose-escalation, dose-expansion Phase 1 study of SYHX2001(name of the experimental drug) in patients with advanced or metastatic cancers who have exhausted standard treatment. The study will consist of 2 parts, a dose escalation part and a cohort expansion part. Once the recommended phase 2 dose (RP2D) has been determined in the dose escalation part, a cohort expansion part involving up to three separate cohorts will be conducted. For patients, the study will include a screening phase, a treatment phase, and a post treatment follow-up phase. An end-of-study visit will be conducted within 30 days after the last dose of SYHX2001.

Exclusion criteria

1. Chemotherapy, radiotherapy, biotherapy, endocrine therapy, targeted therapy, immunotherapy and other anti-tumor treatment within 4 weeks prior to the first dose of the study drug, or administration of other investigational agents within 4 weeks or 5 half-lives prior to the first dose of the study drug, whichever is longer.
