Brief Summary

A Phase I Clinical Study to Evaluate the Safety, Tolerance and Pharmacokinetics of BAT4706 Injection in Patients With Advanced Solid Tumors.

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.

Conditions

Advanced Solid Tumor; Melanoma

Study Design

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

Study Groups

Single group

First Phase: dose escalation study. It was divided into six dose groups: 0.1mg/kg, 0.3mg/kg, 0.5mg/kg ,1.0mg/kg, 3.0mg/kg and 10.0mg/kg. The safety, tolerability and pharmacokinetics of bat4706 injection were explored according to the 3 + 3 dose increasing mode. It is expected that 18-36 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

Group Type: EXPERIMENTAL

BAT4706

Intervention Type: DRUG

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.
