Summary

This trial tests a new drug to see if it's safe and works with chemotherapy to treat advanced cancer.

Who is the study for?
This trial is for adults with certain advanced cancers, including stomach, lung, and breast cancer. Participants must have a specific performance status score and at least one measurable lesion. They should not have received prior treatment for their advanced cancer or progressed within 6 months after platinum-based chemotherapy.
What is being tested?
The study tests the safety of AB598 alone and combined with zimberelimab plus standard chemo drugs like Pemetrexed and Oxaliplatin in patients with advanced malignancies. It aims to find out how well these treatments are tolerated by participants.
What are the potential side effects?
Possible side effects may include typical reactions to immunotherapy such as fatigue, skin reactions, digestive issues, potential immune-related complications affecting various organs, as well as those associated with chemotherapy like nausea and low blood cell counts.
