As safety information pertaining to the long-term use of HU remains incomplete in spite of the first safety study (ESCORT-HU), an extension of the latter is proposed. ESCORT-HU Extension study aims at evaluating the long-term safety of Siklos® focusing on some questions regarding its safety when used in current practice in adults and paediatric patients treated with Siklos® and followed for up to 5 years. The study will focus on the following concerns : occurrence and incidence of malignancies, leg ulcers, male fertility impairment and serious unexpected AEs causally related to Siklos®.
