A Study of BL-M09D1 in Patients With Locally Advanced or Metastatic Non-Small Cell Lung Cancer and Other Solid Tumors

Summary

This study is an open-label, multicenter, dose-escalation and cohort-expansion, non-randomized Phase I clinical trial to evaluate the safety, tolerability, pharmacokinetic characteristics, and preliminary efficacy of BL-M09D1 for injection in patients with locally advanced or metastatic non-small cell lung cancer and other solid tumors.
