What this phase means
Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Biospecimen Collection, Computed Tomography with Contrast, or Echocardiography Test. The registry lists allocation as na. This phase II trial studies how well osimertinib works in treating patients with non-small cell lung cancer with EGFR exon 20 insertion mutation that is stage IIIB-IV or has come back after a period of improvement (recurrent).
They plan to enroll about 46 people at 347 sites. Taking part typically means taking a study drug (or dummy pill), a procedure as part of the study plus check-ins.
