Must have
Patients must have a diagnosis of hormone receptor positive, HER-2 negative, metastatic breast cancer and must be receiving or plan to receive first-line systemic treatment for metastatic disease
Patients with known brain leptomeningeal metastases are not eligible
Screening 3 weeks
Treatment Varies
Follow Up up to 48 weeks after randomization

No Placebo-Only Group

Study Summary

This trial studies how well using markers to prompt when scans should be ordered works in monitoring patients with hormone receptor positive Her2 negative breast cancer.

Who is the study for?
This trial is for adults with hormone receptor positive, HER2 negative metastatic breast cancer who are starting or receiving first-line systemic treatment. They must not be pregnant, have had other cancers (except certain skin/cervical cancers) in the last five years, or conditions like cirrhosis that affect tumor marker levels. Participants need decision-making capacity and can't be in another first-line treatment trial.Check my eligibility
What is being tested?
The study compares usual care disease monitoring to serum tumor marker directed monitoring to see if using blood markers to decide when to do scans is as effective for patients with advanced breast cancer. It includes quality-of-life assessments and anxiety questionnaires.See study design
What are the potential side effects?
Since this trial focuses on monitoring methods rather than new treatments, side effects are related to standard cancer care which may include fatigue, nausea, pain from procedures or tests, and psychological impacts such as increased anxiety.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Assessment of whether patients monitored with STMDDM have non-inferior overall survival compared with patients monitored with usual care
Secondary outcome measures
Assessment of anxiety of patients monitored with STMDDM compared to patients monitored with usual care
Assessment of quality of life of patients monitored with STMDDM versus patients monitored with usual care
Cumulative direct healthcare costs (in the United States) of patients monitored with STMDDM versus usual care

Awards & Highlights

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Arm II (serum tumor directed disease monitoring)Experimental Treatment3 Interventions
Patients undergo disease specific serum tumor marker evaluation (CEA and either CA 15-3 or CA 27.29, whichever were tested at Step 1 Registration and Step 2 Registration) every 4-8 weeks (starting from randomization) without imaging until an elevation of at least one disease specific STM. In the event of an elevated STM, the patient will have imaging within 4 weeks to evaluate for disease progression. Patients continue with STMDDM for up to 312 weeks in the absence of disease progression.
Group II: Arm I (usual care)Active Control3 Interventions
Patients will have imaging studies (modality and frequency per treating physician, however at a minimum frequency of every 12 weeks) alone or in conjunction with STMs (frequency determined by treating physician). Patients will continue with usual care disease monitoring for up to 312 weeks in the absence of disease progression.
