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 Biopsy Procedure, Biospecimen Collection, or Computed Tomography. The registry lists allocation as randomized. This phase II trial compares the effect of usual treatment of docetaxel chemotherapy plus trastuzumab, to ado-emtansine (T-DM1) in patients with HER2-positive salivary gland cancer that has come back (recurrent), that has spread from where it first started (primary site) to other places in the body, or cannot be removed by surgery (unresectable).
They plan to enroll about 146 people at 154 sites. Taking part typically means taking a study drug (or dummy pill), an infusion or injection of a biologic, a procedure as part of the study plus check-ins.
