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, Bone Scan, or Computed Tomography. The registry lists allocation as na. This phase II trial tests how well stereotactic body radiation therapy (SBRT) works in treating patients with estrogen receptor positive (ER +) breast cancer that has spread from where it first started to other places in the body (metastatic) and has limited disease progression (oligoprogression).
They plan to enroll about 18 people at 2 sites. Taking part typically means taking a study drug (or dummy pill), a procedure as part of the study plus check-ins.
Official title (unrewritten)
A Phase II Trial of Stereotactic Body Radiation Therapy and Fluoroestradiol Positron Emission Tomography in Patients With Oligoprogressive Estrogen Receptor Positive Metastatic Breast Cancer
Interventions: Biospecimen Collection, Bone Scan, Computed Tomography, F-18 16 Alpha-Fluoroestradiol, Positron Emission Tomography, Questionnaire Administration, Stereotactic Body Radiation Therapy
Primary outcome (registry wording): Proportion of patients that remain on their original systemic therapy for at least ≥ 24 weeks post stereotactic body radiation therapy (SBRT) treatment
