This phase III trial compares an additional support program (text message reminders and/or telephone-based counseling) with usual care in making sure breast cancer patients take their endocrine therapy medication as prescribed (medication adherence). Medication adherence is how well patients take the medication as prescribed by their doctors, and good medical adherence is when patients take medications correctly. Poor medication adherence has been shown to be a serious barrier to effective treatment for hormone receptor positive breast cancer patients. Adding text message reminders and/or telephone-based counseling to usual care may increase the number of days that patients take their endocrine therapy medication as prescribed.

PRIMARY OBJECTIVES:

I. Compare endocrine therapy (ET) adherence at 12 months in diverse women exposed to text message reminders (TMR)-only, telephone-based motivational interviewing counseling (MI)-only, or both (TMR+MI), versus usual care.

SECONDARY OBJECTIVES:

l. Compare endocrine therapy (ET) adherence at 24 months in diverse women exposed to text message reminders (TMR)-only, telephone-based motivational interviewing counseling (MI)-only, or both (TMR+MI), versus usual care.

OUTLINE: Patients are randomized to 1 of 4 arms.

ARM I (TMR): Patients receive online educational information about ET at the start of their ET medication. Patients also receive daily text message reminders to take their ET medication and monthly text messages about how they are doing with taking their ET medication. These text messages continue for 9 months.

ARM II (MI): Patients receive online educational information about ET at the start of their ET medication. Patients also receive a total of 5 motivational interviewing counseling sessions via telephone over 30-90 minutes for up to 9 months. These sessions are designed to support patients while they take their ET medication, develop health goals, and stay on track in achieving those goals.

ARM III (TMR + MI): Patients receive online educational information about ET at the start of their ET medication. Patients also receive text messages as in Arm I and motivational interviewing counseling sessions as in Arm II.

ARM IV (ENHANCED USUAL CARE): Patients attend usual care clinic visits every 3-6 months and receive online educational information about ET at the start of their ET medication. Patients also receive optional online information about living a healthy life after breast cancer.

After completion of study participation, patients are followed up for up to 24 months.

• Women with an initial pathologically confirmed diagnosis of stage I-III, hormone receptor positive, HER2-neu negative, invasive breast cancer within 18 months prior to enrollment

  • Women who have undergone neo-adjuvant chemotherapy who have no residual invasive disease post-surgery are eligible based on an initial pathologically confirmed diagnosis
  • Hormone receptor positive is defined as estrogen receptor (ER) and/or progesterone receptor (PR) of > 1%
  • HER2-neu negative is defined as 0-1+ by immunohistochemical (IHC) analysis, or non-amplified by fluorescence in situ hybridization (FISH) analysis

• Patients must have received cancer-directed surgery, and/or completed all other adjuvant therapy, except reconstruction

• Patients must have initiated an endocrine therapy drug within the 6 months prior to registration, OR have received a prescription with stated intent to initiate within 6 weeks after registration

• No history of previous cancer as follows:

  • Invasive or non-invasive breast cancer at any time
  • Non-breast cancer, within the past 5 years, excluding non-melanoma skin cancer

• Patients must be willing to use a smart phone for study activities

  • Patient is NOT to be deemed ineligible during the recruitment process if they do not have a smart phone
  • If a participant does not own a smart phone or has limited data or texting capabilities or their smart phone cannot support the Alliance electronic patient reported outcomes (ePRO) survey application (app), a smart phone and service can be provided to the participant at no cost through the Ohio State University (OSU) partnership with Verizon Wireless for the duration of the study activities
  • The CRP is ONLY to discuss this option with those patients who self-identify a phone-related barrier to participation, including: lack of a smart phone, insufficient phone plan (minutes/text/data), or a smart phone incompatible with the Alliance ePRO app
  • For OSU -provided phones, charges will be paid by the grant through the intervention period. At the end of the 12-month intervention period, patients will be responsible for paying monthly fees, if continued service is desired. The physical phones will belong to the patients at the end of their study activities

• Patients must be willing to use a Pillsy medication event monitoring system for the duration of study participation

• In order to complete the mandatory patient-completed measures, participants must be able to speak and read English
