Phase 1 |
Detailed Description
This Phase 1 study is comprised of dose escalation and expansions for KM602 monotherapy. Monotherapy dose escalation is designed with initial accelerated titration followed by a standard 3+3 dose escalation; Patients will remain on study treatment until progression of disease, unacceptable toxicity, or other specified reason for discontinuation.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: KM602 monotherapy Dose escalation and expansion |
Biological: KM602
Multiple dose levels of KM602 will be administered, including 0.01 mg/kg QW, 0.1 mg/kg QW, 0.6 mg/kg QW, 3 mg/kg QW, and 10 mg/kg QW. KM602 is administered intravenously once a week, and each cycle is 21 days.
