Detailed Description
This study is a multicenter, open-label, phase II study of YL202 in China to evaluate the efficacy, safety, and PK characteristics of YL202 in the advanced NSCLC/BC/HNSCC/colorectal cancer/HER2-positive gastric cancer/cervical cancer/ovarian cancer and etc.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Corhort A YL202 is provided as the lyophilized powder, 200 mg/vial. Locally advanced or metastatic NSCLC patients will be given YL202 by intravenously once every 3 weeks (Q3W) as a cycle. |
Drug: YL202 should be intravenously infused
For each patient, YL202 should be intravenously infused over 60±10 min.
|
| Experimental: Corhort B YL202 is provided as the lyophilized powder, 200 mg/vial. Locally advanced or metastatic BC patients will be given YL202 by intravenously once every 3 weeks (Q3W) as a cycle. |
Drug: YL202 should be intravenously infused
For each patient, YL202 should be intravenously infused over 60±10 min.
|
| Experimental: Corhort C YL202 is provided as the lyophilized powder, 200 mg/vial. Locally advanced or metastatic HNSCC patients will be given YL202 by intravenously once every 3 weeks (Q3W) as a cycle. |
Drug: YL202 should be intravenously infused
For each patient, YL202 should be intravenously infused over 60±10 min.
|
| Experimental: Corhort D YL202 is provided as the lyophilized powder, 200 mg/vial. Other locally advanced cancer patients will be given YL202 by intravenously once every 3 weeks (Q3W) as a cycle. |
Drug: YL202 should be intravenously infused
For each patient, YL202 should be intravenously infused over 60±10 min.
