Abstract BACKGROUND: Metastatic breast cancer (mBC) remains an incurable disease and is the cause of nearly all deaths from breast cancer. Targeted molecular therapies and the evolving role of next-generation sequencing (NGS) technologies are increasing and may improve outcomes in breast cancer patients. However, they are not being routinely used in the clinic. One strategy to overcome the barriers of implementing NGS in the clinic is to promote the active participation of mBC patients in the management of their disease. With this in mind, we designed HOPE (SOLTI-1903), a national real-world study where patients lead their inclusion, participation and follow-up in the study through a digital tool that will guide them in every step of the journey. Our objective is empowering mBC patients and gather real-world data about the utilization of molecular information in the management of mBC. TRIAL DESIGN: Patients diagnosed with mBC who are receiving, have just received, or will receive standard treatment or treatment in a clinical trial (CT) can be included. Demographic data, disease characteristics, treatment history and quality of life data will be collected through a digital tool (DT) by the patient. Patients are encouraged to involve their physician`s in the study journey. The study is complemented by a patient empowerment program including informative workshops and precision medicine video-tutorials. A total of 600 patients will be included in Spain. Patient Journey Once patients request to participate in HOPE through the DT, a dedicated team from SOLTI will assist them in the following steps while validating that eligibility criteria are met according to data introduced by themselves. Then, patients will receive instructions via DT to go to the nearest partner local laboratory, where they will sign the study consent form. A metastatic (preferably) or primary archival tumor sample will be requested to the patient’s reference hospital and analyzed by FoundationOne®CDx. Also, a blood sample will be collected and analyzed by Guardant360. For all patients, two NGS tests will be offered (If no tissue available, only blood test will be performed). Both molecular analyses results will be reviewed during regular meetings by a Molecular Advisory Board (MAB). The MAB, based on their joint experience in clinical oncology, genomics, molecular biology, bioethics and pathology, may add some advice to these reports via DT, making comments about detected molecular alterations and adding further recommendations for specific treatment options or available CT with targeted therapies. From that moment, patients will record their disease evolution in the DT each 3 months for 2 years. The primary objective is to assess the real-world clinical practice integrating molecular profiling in the Standard of Care management of mBC patients connected through a DT. Secondary objectives include to describe genetic mutational profile of mBC, to evaluate the enrollment rate in CT of patients engaged in a patient-centered strategy for molecular tumor assessment, to asses Progression Free Survival, Overall Survival and Quality of life status among patients enrolled in CT according to the tumor’s genomic profile and those receiving standard treatment and to describe logistic feasibility of the study. This study is sponsored by SOLTI and financially supported by Novartis and two non-profit organizations: Asociación Cáncer de Mama Metastásico y Fundación Actitud frente al Cáncer. Roche and Guardant Health provide their test for all patients.
