JY016 Injection in Patients With Advanced Solid Tumors Expressing EGFR

Starting soon · Phase 1/Phase 2

Conditions studied: Solid Cancers

In brief

This study is a single-arm, open-label, multi-center Phase I/II clinical trial, consisting of Part A: the Phase I dose escalation stage, and Part B: the Phase II expansion stage. The objective of the Phase I dose escalation stage is to evaluate the safety, pharmacokinetic characteristics, and preliminary efficacy of JY016 injection in patients with advanced solid tumors expressing EGFR (immunohistochemistry 1+, 2+, or 3+). In the Phase II stage, the efficacy of JY016 in pancreatic cancer, non-small cell lung cancer, esophageal cancer, colorectal cancer, and squamous cell carcinoma of the head and neck with EGFR expression will be further evaluated.
