What this phase means
This study does not use the classic phase 1–4 drug ladder. It may be a device, a behavior program, a surgery timing study, or an early feasibility test.
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 Usual care disease monitoring, Serum Tumor Marker directed disease monitoring, or Quality-of-Life Assessment. The registry lists allocation as randomized. This randomly assigned research trial studies how well serum tumor marker directed disease monitoring works in monitoring patients with hormone receptor positive Her2 negative breast cancer that has spread to other places in the body.
They plan to enroll about 739 people at 723 sites. Taking part typically means study visits and measurements plus check-ins.
Official title (unrewritten)
Randomized Non-Inferiority Trial Comparing Overall Survival of Patients Monitored With Serum Tumor Marker Directed Disease Monitoring (STMDDM) Versus Usual Care in Patients With Metastatic Hormone Receptor Positive Breast Cancer
Interventions: Usual care disease monitoring, Serum Tumor Marker directed disease monitoring, Quality-of-Life Assessment, Anxiety Questionnaire Administration
Primary outcome (registry wording): Assessment of whether patients monitored with STMDDM have non-inferior overall survival compared with patients monitored with usual care
