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 WSD0922-FU Tablets, Dose level A, or WSD0922-FU Tablets, Dose level B. The registry lists allocation as randomized. This is a Phase II, Open Label, Multicenter, Single Arm Study of WSD0922-FU for Patients with Locally Advanced or Metastatic Non-Small Cell Lung Cancer whose Disease has Progressed with First-Line Osimertinib Treatment and whose Tumors harbor a C797S mutation within the Epidermal Growth Factor Receptor Gene.
They plan to enroll about 40 people at 16 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
