ClinConnect Summary

This clinical trial is studying a new treatment called HFB200301, which is being tested alone and in combination with another drug called tislelizumab for patients with advanced cancers such as gastric cancer, melanoma, and lung cancer. The main goal of the study is to find out if HFB200301 is safe and to determine the best dose for patients. The trial has two parts: first, researchers will gradually increase the dose to find the highest amount that is safe to use. Then, they will give this determined dose to participants based on the type of cancer they have.

To participate, patients need to have already received multiple treatments for their advanced cancer and have measurable disease that can be evaluated. They should be in relatively good health, meaning they can perform daily activities. Participants will receive regular check-ups and monitoring throughout the trial to ensure their safety and to see how well the treatment works. It’s important to know that there are specific criteria that may exclude some patients, such as recent treatments or certain medical conditions, so discussing eligibility with a healthcare provider is essential.
