A Phase I Study of SHR-4712 in Patients With Advanced Solid Tumors

A Phase I Clinical Study on the Safety, Tolerability, Pharmacokinetics and Efficacy of SHR-4712 in Patients With Advanced Solid Tumors

This is a Phase 1, open label, first-in-human study to evaluate safety, tolerability, Pharmacokinetics (PK), Pharmacodynamics (PD), immunogenicity and anti-tumor activity of SHR-4712 in patients with advanced solid tumors. Patients will treat with SHR-4712 until unacceptable toxicity or disease progression.

4. The subject's ECOG performance status is 0 or 1.
5. The expected survival time is ≥ 12 weeks.
6. The subject has at least one measurable lesion that meets the requirements of RECIST v1.1.
7. Laboratory test results confirm that the subject has sufficient functions of vital organs.
8. Female subjects of child-bearing potential must not be breastfeeding, have no possibility of pregnancy, and agree to comply with relevant contraceptive requirements.
