Conditions

Lung Cancer (Non-Small Cell)

Brief summary

This is a multicenter, phase II study. The purpose of this study is to evaluate the safety and preliminary anti-tumor activity of SKB571 in patients with advanced non-small cell lung cancer. Eligible subjects will receive SKB571 monotherapy, until radiographic disease progression, intolerable toxicity, discontinuation of study treatment required by the subject, or other protocol-specified treatment discontinuation criteria, whichever occurs first.

Interventions

SKB571 for injection is administered every 3 weeks(Q3W) until radiographic disease progression,intolerable toxicity, or other protocol-specified treatment discontinuation criteria, whichever occurs first.
