What this phase means
Phase 1: the first tests in people. The main question is safety and dose, not whether it cures the condition. Groups are small. Side effects are watched 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 Azenosertib, Biopsy Procedure, or Biospecimen Collection. The registry lists allocation as randomized. This phase I trial tests the safety, side effects, and best dose of azenosertib in combination with trastuzumab deruxtecan in treating patients with HER2-positive gastric or gastroesophageal junction cancer and other HER2-positive solid tumors that have spread to nearby tissue or lymph nodes (locally advanced), that have spread from where it first started (primary site) to other places in the body (metastatic), or that cannot be removed by surgery (unresectable).
They plan to enroll about 48 people at Houston. 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.
