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 DS-3939a, Pembrolizumab, or Carboplatin. The registry lists allocation as randomized. The primary purpose of the study is to measure the safety, tolerability, and how well it works of DS-3939a in combination with other anticancer agents or as a this drug alone in participants with solid tumors.
They plan to enroll about 400 people at 76 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
