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 (Tagrisso®), or WSD0922-FU. The registry lists allocation as randomized. This is a Phase I/II, Open Label Study of WSD0922-FU in Combination with Osimertinib for Patients with Locally Advanced or Metastatic Non-Small Cell Lung Cancer whose disease has progressed with third-generation EGFR-TKI with C797S mutation or is newly diagnosed with CNS metastasis with EGFR Del19 or L858R mutation
They plan to enroll about 48 people at 3 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
