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 6 countries, including North America, United Arab Emirates and countries in Europe, at 19 sites known to treat and follow-up patients with MF/SS. Patients will be followed for up to 50 weeks from study enrollment.
