Brief Summary

This clinical trial evaluates the feasibility and acceptability of a mobile health device in improving oral chemotherapy adherence in women with triple negative breast cancer that has not spread to other places in the body (non-metastatic). A mobile health device, called SMRxT smart pill bottle may help doctors to remind patients to take medicine on time and monitor their symptoms.

Detailed Description

PRIMARY OBJECTIVES:

I. Feasibility. II. Acceptability. III. Capecitabine/Xeloda adherence.

EXPLORATORY OBJECTIVES:

I. Symptom burden. II. Patent physician communication. III. Quality of life. IV. Self-efficacy for managing symptoms.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP I: Patients receive a SMRxT smart pill bottle, report symptoms weekly, and receive reminders for missing or incorrect dose for standard of care 3-week capecitabine/Xeloda treatment cycles.

GROUP II: Patients receive standard of care.

After completion of study, patients are followed up for 90 days after the initiation of capecitabine/Xeloda.

Primary Outcome Measures

Name	Time	Method
Medication adherence	From baseline up to 90 days	Proportion of times each patient took her scheduled medication during the 3-month study. For each patient, will operationalize adherence as the number of times that the pill monitor recorded a dose taken for each day that the patient was in the study and supposed to take the pill. Days during which patients were off cycle, advised by their provider to temporarily stop the medication, or hospitalized will be deducted from the total days in the study.

Secondary Outcome Measures

Name	Time	Method
Acceptability	From baseline up to 90 days	Will be measured using survey questions about the intervention after the 90-day intervention. Acceptability and usability will be determined using the System Usability Scale.
End-user engagement by patients and their oncology team	From baseline up to 90 days	Will measure patient's use of the smart pill bottle, their response to weekly symptoms text message questions, response to the smart reminders, and response to the adherence reason text message question. In addition, will also measure and evaluate the provider response to any adherence or symptom alerts triggered during the intervention.
