Clinical Trial Summary

This is a multicenter, open-label, multiple-dose dose finding and expansion study to evaluate the safety, tolerability, pharmacokinetic(PK) profile, and anti-tumor efficacy of SKB410 for injection in patients with advanced solid tumors.

Description:

This is a multicenter, open-label, multiple-dose dose finding and expansion study to evaluate the safety, tolerability, PK profile, and anti-tumor efficacy of SKB410 for injection in patients with advanced solid tumors.This study consists of two phases, Phase Ia and Phase Ib: Phase Ia is a dose escalation phase, and subjects with advanced solid tumors will be enrolled to receive SKB410 for Injection; Phase Ib is a dose expansion phase, and the expansion dose(s) for specific cancer will be determined based on Phase Ia result.

4. Has received strong cytochrome P450 (CYP3A4) inhibitors or inducers (see Annex 4) within 2 weeks prior to the first dose or within 5 half-lives of known drug, whichever is longer.

5. Has not recovered to normal or = Grade 1 from any AE and/or complication due to any prior therapy (except alopecia or pigmentation).

6. Has known history of allergy to any component of SKB410 or other monoclonal antibodies.

7. Has a known previous or concurrent other malignancies within 5 years prior to signing the ICF.

8. Presence of active central nervous system (CNS) metastases and/or carcinomatous meningitis.
