Overview
Brief Summary
This is a phase I, open-label, multi-center, dose escalation and expansion study in advanced or metastatic solid tumor patients. The're are two goals set in this study: one is to explore the safety and tolerability of KGX101 when mono and combo with envafolimab in Chinese patients, the other is to determine recommended phase 2 dose of KGX101 mono and combo with envafolimab. Participants will: 1. Take drug KGX101 mono or combo with envafolimab every 3 weeks; 2. Visit the clinic for checkups and tests. Schedule will be about 6-8 times in the first month and then about every 3 weeks afterwards.
