Summary

This trial is testing a new cancer drug, ENB003, to see if it is safe and effective. The study will first test the drug on a small group of people to see what doses are safe. Then the study will be expanded to include more people with different types of cancer.

Who is the study for?
This trial is for adults with certain solid tumors, including metastatic melanoma, platinum-resistant ovarian cancer, and pancreatic cancer. Participants must have tried some standard treatments without success and can't have had more than three prior systemic therapies. Pregnant women or those who've had severe reactions to similar drugs are excluded.Check my eligibility
What is being tested?
The study tests ENB003 combined with Pembrolizumab on patients with solid tumors. It has two parts: Part A finds the safest dose (RP2D) through a '3+3' method; Part B expands the trial using this dose on specific cancers, including an exploratory group of sarcoma patients.See study design
What are the potential side effects?
Possible side effects include immune-related issues due to both drugs being immunotherapies which may cause inflammation in various organs, infusion reactions related to the drug administration process, fatigue from treatment burden, digestive problems like nausea or diarrhea, blood disorders such as anemia or clotting issues.
