Siklos® is indicated to reduce the frequency of painful crises and the need for blood transfusions in pediatric patients, two years of age and older, with sickle cell anemia with recurrent moderate to severe painful crises. It is the first and only FDA-approved hydroxyurea-based treatment for use in pediatric patients with sickle cell anemia.

Medunik USA holds the exclusive rights to market and distribute Siklos® in the United States, through an agreement with ADDMEDICA, a French pharmaceutical company specializing in hematology.

"We are pleased to partner with ADDMEDICA to provide access to an orphan drug therapy that can contribute to reducing painful crises, specifically for children with sickle cell anemia," said Éric Gervais, Executive Vice President of Medunik. "The addition of Siklos® to the Medunik portfolio establishes our footprint in the United States in the area of orphan drug therapies and is the latest in a series of significant advances for our company."

 "Medunik USA is well positioned to ensure both the marketing and distribution of Siklos® in the United States, thanks to their knowledge of the orphan drug commercialization process. We are pleased to count them as a partner," said Bernard Dauvergne, Executive Director of ADDMEDICA.

Sickle cell anemia (SCA) is the most common inherited blood disorder, resulting in the production of abnormal hemoglobin, known as hemoglobin-S (HbS), responsible for the sickling of red blood cells. This disease affects nearly 100,000 Americans, decreases life expectancy by 25 to 30 years, induces significant morbidity, and therefore, reduces quality of life1,2.  Most of those affected are of African ancestry; a minority are of Hispanic or southern European, Middle Eastern or Asian Indian descent3.

"This approval is a major milestone in treatment for all children who suffer from devastating pain and disability associated with sickle cell anemia," said Abbey Meyers, Founder and past-president of the National Organization for Rare Disorders (NORD) and member of Medunik's Advisory Board.

FDA approval was granted based on tolerability and effectiveness data collected in a European sickle cell disease cohort (Escort-HU) study, which included 405 pediatric patients. Data showed that treatment with Siklos® increased the concentration of fetal hemoglobin (hemoglobin F or HbF), which prevents the sickling process within red blood cells. In the clinical trial, the number of pediatric patients experiencing at least one painful crisis in the 12 months prior to treatment with Siklos® was significantly reduced after 12 months of treatment4.

Siklos® offers flexible dosing to facilitate adjustment based on patient's weight and maximum tolerated dose. This is particularly important in pediatric populations, where patient weight is constantly changing.
