Scientists dig deeper into ALK lung cancer to unlock resistance secrets
NCT ID NCT05122806
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at the biological features of a specific type of lung cancer (ALK-positive) in 100 patients. Researchers will analyze tumor samples and blood tests taken at diagnosis and when the disease worsens. The goal is to learn why some treatments stop working, not to test a new therapy.
