What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 295 participants in total. It began in 2026-01-19 with a primary completion date of 2028-01-19.

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.
