Background: Efficacy and quality of life (QoL) are key when selecting a therapy for metastatic breast cancer (MBC) patients. In hormone receptor positive (HR+) human epidermal growth factor receptor 2 minus (HER2-) MBC, addition of targeted oral agents such as everolimus or a cycline-dependent kinase 4/6 (CDK 4/6) inhibitor (e.g. palbociclib, ribociclib, abemaciclib) to endocrine therapy substantially prolongs progression-free survival and in the case of a CDK 4/6i also overall survival. Prerequiste for obtaining such benefit is adherence to therapy over the whole treatment duration. Adherence, maintaining patients’ satisfaction, early detection and management of side effects have thus become important challenges, in particular with these new oral drugs and new ways of continuous support for oncological patients are needed. An eHealth-based platform can help to support therapy management and physician-patient interaction.
Methods: PreCycle is a multicenter, randomized, phase IV trial in HR+ HER2+ MBC. All patients (n=960) receive the CDK 4/6 inhibitor palbociclib either in first (62.5%) or later line (37.5%) together with endocrine therapy (AI, fulvestrant) according to national guidelines. PreCycle evaluates the time to deterioration (TTD) of QoL in patients supported by eHealth systems with substantially different functionality: CANKADO active vs. inform. CANKADO active is the fully functional CANKADO-based eHealth treatment support system. CANKADO inform is a CANKADO-based eHealth service with a personal login, documentation of daily drug intake, but no further functions. To evaluate QoL, the FACT-B questionnaire is completed at every visit. As little is known about relationships between behavior (e.g. adherence), genetic background, and drug efficacy, the trial includes both patient reported outcome and biomarker screening for discovery of forecast models for adherence, symptoms, QoL, progression free survival (PFS), and overall survival (OS).
Discussion: The primary objective of PreCycle is to test the hypothesis of superiority for time to deterioration (TTD) in terms of DQoL = “Deterioration of quality of life” (FACT-G scale) in patients supported by an eHealth therapy management system (CANKADO active) versus in patients merely receiving eHealth-based information (CANKADO inform).
