Brief Summary

Phase 1, First in Human, Open-Label, Dose-Escalation Study of 609A in the Patients with Locally advanced/Metastatic Solid Tumors in China.

Detailed Description

This is a first-in-human (FIH), open-label, phase 1 dose-escalation study of 609A in China, a recombinant monoclonal anti-PD-1 antibody product, in subjects with Locally advanced/Metastatic Solid Tumors, who must have failed standard treatment (disease progression or intolerance) or lack of standard treatment. If there is a driver gene variant, the subjects must have failed the standard treatment for the driver gene, and there is no other standard treatment.

Conditions

Solid Tumors

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

609A group

Dose escalation will be conducted using a traditional 3+3 design. Dose Escalation Level cohort 1. Dose 1 mg/kg, Q3W, IV. Subjects 3-6； Dose Escalation Level cohort 2. Dose 3 mg/kg, Q3W, IV. Subjects 3-6； Dose Escalation Level cohort 3. Dose 200mg, Q3W, IV. Subjects 3-6； Dose Escalation Level cohort 4. Dose 10 mg/kg, Q3W, IV. Subjects 3-6. If 10mg/kg cannot be tolerated, add a dose level of 400mg to assess the tolerance

Group Type: EXPERIMENTAL

Women of childbearing potential must have a negative pregnancy test ≤ 72 hours prior to the first dose of study drug. Postmenopausal women must have been amenorrhoeic for at least 12 months to be considered of non-childbearing potential.

Exclusion Criteria
