| Phase 1 |
Detailed Description
This study is a single center, open, dose increasing and dose expanding phase I clinical study. The dose increasing method of "3 + 3" is used to explore the safety, tolerance and PK characteristics of BAT4706 injection in patients with advanced solid tumors. After the completion of dose increment, 1-2 tolerated doses were selected for extended research on melanoma (20-40 cases), so as to provide recommended doses for subsequent clinical trials.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Single group First Phase: dose escalation study. It was divided into four dose groups: 0.1mg/kg, 0.3mg/kg, 0.5mg/kg and 1.0mg/kg. The safety, tolerability and pharmacokinetics of bat4706 injection were explored according to the 3 + 3 dose increasing mode. It is expected that 12-24 cases will be included in the group Second Phase: dose expansion study. After the completion of dose increment, 1-2 tolerated doses were selected for extended research on melanoma (20-40 cases), so as to provide recommended doses for subsequent clinical trials |
Drug: BAT4706
The administration cycle was proposed to be 3 weeks (Q3W), i.e., 21 days in a cycle, and the first 4 cycles were administered on the first day of each cycle.
