RecruitingBehavioural interventionMobile Health Intervention to Improve Adherence to Oral Anticancer TherapyNew oral anticancer treatments have improved survival across cancer types but introduced challenges in medication adherence and symptom management. The SMART pilot trial will test a new mobile health intervention that facilitates remote adherence and symptom monitoring, patient-provider communication outside of clinic visits regarding the use of oral anticancer treatments, and support for financial and social needs, as well as health literacy support, for 30 English- and Spanish-speaking patients. This study will increase understanding of barriers and facilitators to the use of the proposed mHealth intervention.
