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 Osimertinib, Carboplatin, or Pemetrexed. The registry lists allocation as randomized. This study will compare the effectiveness of osimertinib alone with the combination of osimertinib and chemotherapy (carboplatin and pemetrexed) in people with metastatic lung cancer that has a change (mutation) in the gene EGFR.
They plan to enroll about 571 people at 18 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
Official title (unrewritten)
A Phase 2 Randomized Study of Osimertinib Versus Osimertinib Plus Chemotherapy for Patients With Metastatic EGFR-Mutant Lung Cancers That Have Detectable EGFR-Mutant cfDNA in Plasma After Initiation of Osimertinib
Interventions: Osimertinib, Carboplatin, Pemetrexed
Primary outcome (registry wording): Determine the progression-free survival
