Awards & highlights


This trial is testing a new drug, YL211, on patients with advanced solid tumors. It consists of three parts: dose escalation, backfill enrollment, and dose expansion. The goal is to

Who is the study for?
This trial is for individuals with advanced solid tumors who have likely tried other treatments without success. Specific details about eligibility criteria are not provided, but typically participants must be adults in stable condition and able to comply with study requirements.Check my eligibility
What is being tested?
YL211 is being tested in this Phase I trial. It's given intravenously to patients with advanced solid tumors across three parts: dose-escalation to find the maximum tolerated dose (MTD), backfill enrollment to confirm safety and efficacy, and dose-expansion at MTD to further assess its effects.See study design
What are the potential side effects?
As YL211 is a new treatment under investigation, specific side effects are not listed here. Generally, such drugs can cause reactions at the infusion site, fatigue, nausea, or more serious conditions depending on how they work against cancer cells.
