| Patients Enrolled |
Patients with EGFR mutant locally advanced or metastatic NSCLC
|
||||
| Related Clinical Trial | |||||
| NCT Number | CTR20243230 | Phase Status | Phase 3 | ||
| Clinical Description |
A randomized, open, multicenter, phase I/III trial to evaluate the safety and efficacy of SYS6010 in combination with ocitinib in patients with EGFR-mutated locally advanced or metastatic non-small cell lung cancer
|
||||
| Experiment 2 Reporting the Activity Date of This ADC | [2] | ||||
| Patients Enrolled |
Age ≥18 years, Patients with histologically confirmed locally advanced or metastatic solid tumors who have disease progression, intolerance to prior therapy, are ineligible for available therapies, or refuse standard of care therapy in the metastatic setting.In Part A, patients with solid tumors including but not limited to NSCLC (adenocarcinoma and squamous cell carcinoma), breast cancer, KRAS-wild type colorectal cancer, and head & neck cancer based on previous biopsy result.In Part B, Cohort 1 will exclusively include NSCLC patients with documented EGFR mutations based on previous biopsy result and Cohort 2 will be patients with other cancer (s) suggested to have sensitivity to CPO301 in Part A.
