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 Biospecimen Collection, Computed Tomography, or Positron Emission Tomography. The registry lists allocation as randomized. This phase II trial tests the safety of positron emission tomography (PET) guided stereotactic body radiation therapy (SBRT) and how well it works to treat non-small cell lung cancer (NSCLC), melanoma, and renal cell carcinoma (RCC) that has up to 5 sites of progression (oligoprogression) compared to standard SBRT.
They plan to enroll about 32 people at 2 sites. Taking part typically means a procedure as part of the study plus check-ins.
