Обзор

This is a multicenter, open-label, phase Ib/II study of YL202 in combination with other anti-tumor therapies to Evaluate the Safety, Tolerability, and Efficacy in Patients with Advanced Solid Tumors

Вмешательства

• Препарат YL202 for injection; Toripalimab injection
  Part 1: YL202 and Toripalimab will be administered intravenously. Part 3: participants will receive escalating doses of YL202 and fixed dose of Toripalimab until YL202 doses for optimization are determined. Dose expansion stage: participants will receive a dose of YL202 not exceeding the maximum dose level achieved during the dose-escalation stage and fixed dose of Toripalimab
• Препарат YL202 for injection; Furmonertinib Mesilate Tablets
  Part 2: YL202 will be administered intravenously，Furmonertinib Mesilate Tablets will be administered orally. Dose escalation stage: participants will receive escalating doses of YL202 and fixed dose of Furmonertinib Mesilate until YL202 doses for optimization are determined. Part 4: participants will receive a dose of YL202 not exceeding the maximum dose level achieved during the dose-escalation stage and fixed dose of Furmonertinib Mesilate.
