S1105: Text-Messaging Intervention to Reduce Early Discontinuation of AI Therapy in Women With Early-Stage Breast Cancer

S1105, Randomized Trial Of Text-Messaging Intervention To Reduce Early Discontinuation Of Adjuvant Aromatase Inhibitor Therapy In Women With Early Stage Breast Cancer

RATIONALE: Measuring how text-message affects treatment compliance in women with breast cancer may help doctors plan the best treatment.

PURPOSE: This randomized trial studies how well text-message works in reducing early discontinuation of aromatase inhibitor therapy in patients with early-stage breast cancer who underwent breast surgery.

Study Overview

• Status: Completed
• Conditions: Breast Cancer
• Intervention / Treatment: Behavioral: Text message reminder

Detailed Description

OBJECTIVES:

Primary

• To determine the efficacy of a reminder message, sent by text message to mobile phones twice weekly, to improve adherence to adjuvant aromatase inhibitor (AI) therapy as determined by urinary AI levels in women with early-stage hormone-sensitive breast cancer versus usual care.

Secondary

• To compare the effect of a reminder message sent twice weekly to mobile phones as compared to usual care to improve adherence to adjuvant AI therapy according to self-report.
• To explore the efficacy of the text message intervention for reducing early discontinuation as compared to usual care at 12, 24, and 36 months of adjuvant AI therapy in subgroups of breast cancer patients as defined by age group, stage, year of therapy, education, race/ethnicity, teaching hospital versus community hospital, AI-related side effects (as determined by serial questionnaires), insurance status, and prescription co-pay status.
• To explore the reasons for early discontinuation of AI therapy in those who do discontinue in the intervention and control group by querying quality of life as assessed by the Functional Assessment of Cancer Therapy-Endocrine Subscales (FACT-ES) and symptoms and other issues related to hormonal therapy at each follow-up visit, using the Brief Pain Inventory (BPI-SF), and at annual visits the Beliefs about Medicine Questionnaire (BQM) and the Treatment Satisfaction Questionnaire for Medication (TSQM).
• To conduct a sensitivity analysis assessing time to last evidence of adherence.

OUTLINE: This is a multicenter study. Patients are stratified according to length of time on aromatase inhibitor (AI) (< 12 months vs 12-24 months), and type of AI (anastrozole vs letrozole vs exemestane). Patients are randomized to 1 of 2 intervention arms.

• Arm I: Patients undergo a text message education checklist involving confirmation of cellular telephone capability to receive text messages, how to retrieve and read messages, including a confirmation evaluation, at baseline and at any time a patient obtains a new cellular telephone. Patients then receive a text message twice a week at 8 o'clock in the morning (for each time zone) for up to 3 years.
• Arm II: Patients receive standard follow-up care. Patients undergo urine sample collection at baseline and periodically during study for aromatase inhibitor level analysis and future translational studies.

Patients complete the Functional Assessment of Cancer Therapy-Endocrine Subscales (FACT-ES), the Brief Pain Inventory (BPI-SF), Beliefs about Medicine Questionnaire (BQM), and the Treatment Satisfaction Questionnaire for Medication (TSQM) questionnaires at baseline and periodically during study. Patients in arm I also complete the Cell Phone and Text Messaging Use Questionnaire at baseline and periodically during study.

In both arms, patients are followed up every 3 months for up to 3 years from registration.

• Patients must be women with a diagnosis of histologically confirmed, primary invasive, hormone-sensitive (estrogen receptor-positive [ER]/progesterone receptor [PR]-positive) adenocarcinoma of the breast (Stage I, II or III) with no evidence of recurrent or metastatic disease (M0)
• Patients must have a mobile phone that can receive text messages and must currently use or be willing to learn to use text messaging

PATIENT CHARACTERISTICS:

• Patients must be postmenopausal, as defined by at least one of the following:

  • ≥ 12 months since the last menstrual period
  • Prior bilateral oophorectomy
  • Previous hysterectomy with one or both ovaries left in place (or previous hysterectomy in which documentation of bilateral oophorectomy is unavailable) AND follicle-stimulating hormone (FSH) values consistent with the institutional normal values for the postmenopausal state; FSH levels must be obtained within 28 days prior to registration
• Patients must be willing to provide urine specimen to test for the presence of aromatase inhibitor within 28 days of randomization and at each 3-month clinic visit for 3 years
• Patients must have the ability to speak and read English
• Patients must have a Zubrod performance status of 0 - 2
• No other prior malignancy (i.e., other than as noted on disease characteristics) is allowed except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer for which the patient has been disease-free for > 5 years
• Patients are allowed to participate in another clinical trial as long as it does not interfere with daily intake of aromatase-inhibitor therapy

PRIOR CONCURRENT THERAPY:

• Patients must be post adjuvant chemotherapy (if to be utilized) and primary curative surgery and must have recovered from all side-effects of the surgery

  • Trastuzumab (Herceptin) given alone after cytotoxic chemotherapy is considered adjuvant chemotherapy; patients would be eligible upon completion of Herceptin as long as the other eligibility criteria are met
• Patients must be currently taking an aromatase inhibitor (AI), have completed at least one month of AI therapy, be within the first 5 years of planned AI therapy, and have at least 3 years remaining before completion of planned AI therapy

Exclusion criteria: Insufficient evidence of post-menopausal status; metastatic or recurrent disease; currently receiving chemotherapy.

Number of Arms

2

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Text message reminder; Patients undergo a text message education checklist involving confirmation of cellular telephone capability to receive text messages, how to retrieve and read messages, including a confirmation evaluation, at baseline and at any time a patient obtains a new cellular telephone. Patients then receive a text message twice a week at 8 o'clock in the morning (for each time zone) for up to 3 years. Additionally, patients receive standard follow-up care.	Behavioral: Text message reminder; Receive text message
No Intervention: No text message reminder; Patients receive standard follow-up care.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Time to first evidence of adherence failure (discontinuation)	Every 3 months after randomization

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Adherence effect of text message compared to usual care using the patient self-report responses to AI Usage form		Every 3 months after randomization
Relationship between randomized arm and various participant, site and health insurance characteristics	Relationship between randomized arm and the following factors: age group, stage, years of therapy, education, race/ethnicity, teaching hospital versus community hospital, AI-related side effects, insurance status, and prescription co-pay status.	Every 3 months after randomization
Reasons for early discontinuation of AI therapy among intervention arm and control arm as assessed by quality-of-life questionnaires		Every 3 months after randomization
Time to last evidence of adherence		Every 3 months after randomization
