A prospective observational study to assess clinical decision-making, prognosis, quality of life and satisfaction with care in patients with relapsed/refractory multiple myeloma: the CLARITY study protocol

Treatment decision-making in patients with relapsed/refractory multiple myeloma (RRMM) is challenging for a number of reasons including, the heterogeneity of disease at relapse and the number of possible therapeutic approaches. This study broadly aims to generate new evidence-based data to facilitate clinical decision-making in RRMM patients. The primary objective is to investigate the prognostic value of patient self-reported fatigue severity for overall survival.
