The PROSPER study aims to collect information about the experiences of patients with MF/SS receiving Poteligeo and of their caregivers in real-world clinical practice. The objective of this study is to generate patient-level data to provide insights into real world clinical practice and an understanding of treatment decisions, as well as to collect patient reported outcomes (PRO) data, enriched with qualitative data on disease and treatment experience and burden, to demonstrate the full impact of treatment and the relevant patient experience in real-world clinical practice. The study will be conducted in up to 8 countries, including North America and countries in Europe, at approximately 20 sites known to treat and follow-up patients with MF/SS. Patients will be followed for up to 50 weeks from study enrollment.
This is a prospective, observational, non-interventional, international, multi-center, mixed methods study that will involve the integration of quantitative and qualitative data in patients with MF/SS treated with Poteligeo.
