Brief Summary

This is an open-label, dose-escalation and dose-expansion phase I clinical study to evaluate the safety and tolerability of JS006 as Monotherapy and in combination with toripalimab in patients with advanced tumors who have failed standard therapies or who have no standard therapy. It is planned to enroll 69-176 patients into the study.

Conditions

Advanced Tumors

Outcome Measures

Primary Outcomes (2)

• To evaluate the safety and tolerability of JS006 as Monotherapy and in combination with toripalimab in patients with advanced tumors

  Incidence and severity of dose limiting toxicity (DLT), adverse events (AEs), serious adverse events (SAEs), and immune-related adverse events (irAEs); abnormal changes with clinical significance in the laboratory and other tests

  2 years

• Determing the maximum tolerated dose and the recommended phase II dose for JS006 as Monotherapy and in combination with toripalimab in patients with advanced tumors

  Maximum tolerated dose: Dose Limitted Toxictiy events occurred at a rate less than 1/3 of the maximum tolerated dose. Phase II recommended dose: safety, pharmacokinetics, and preliminary efficacy data of dose escalation will be integrated. When the Maximum tolerated dose(MTD) is determined, the Maximum tolerated dose(MTD) is usually used as the Phase II recommended dose(RP2D), or the dose lower than the Maximum tolerated dose(MTD) is selected as the Phase II recommended dose(RP2D) based on the comprehensive data.
