A Phase II Clinical Study of SKB571 as Monotherapy in Patients With Locally Advanced or Metastatic Non-Small Cell Lung Cancer With MET Abnormalities

Recruiting now · Phase 2

Conditions studied: Non-small Lung Cancer

In brief

The aim of the study to evaluate the safety and efficacy of SKB571 for injection as monotherapy in patients with locally advanced or metastatic Non-Small Cell Lung Cancer with MET abnormalities. 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.
