Interventions
Biological: SIBP-03
Registration Number
NCT05203601
Lead Sponsor
Shanghai Institute Of Biological Products
Brief Summary

The main purpose of

• To evaluate the safety, tolerability and pharmacokinetic characteristics of SIBP-03(Recombinant anti-HER3 humanized monoclonal antibody injection).

A secondary purpose

* Assess the immunogenicity of SIBP-03. Exploratory purpose

* Explore potential biomarkers;

* Preliminary evaluation of the antitumor efficacy of SIBP-03.

Detailed Description

To evaluate the safety, tolerability, pharmacokinetics, immunogenicity and preliminary efficacy of recombinant anti-HER3 humanized monoclonal antibody injection when treating the patients with advanced malignant solid tumors. This study is an open, multi-dose escalation and extension study of single and multiple dosing. This study was divided into two phases: the first phase was dose escalation phase, the second phase was joint expansion phase, in which the dose escalation phase was a single-center study, and the joint expansion phase was a multi-center study. Stage 1, dose escalation stage: Six dose groups of 2, 5, 10, 15, 20 and 40 mg/kg were planned, then exploring the most appropriate dose. The second stage, combined use extension stage: According to the preliminary data of drug safety, tolerance, pharmacokinetics and efficacy obtained in the dose escalation stage, combined with the clinical study results of similar drugs, 5mg/kg and 10mg/kg dose levels were selected to enter the combined extension stage and used in patients with advanced head and neck squamous cell carcinoma or with breast cancer.
