Medunik USA expands Siklos® (hydroxyurea) coverage under Medicaid Programs to 37 states

PRINCETON, N.J., July 22, 2025 /PRNewswire/ - Medunik USA, a specialty pharmaceutical company dedicated to providing rare disease patients with access to orphan drugs and part of Duchesnay Pharmaceutical Group (DPG), winner of the 2024 Life Sciences Innovation Award by ADRIQ, is pleased to announce that public reimbursement for Siklos® (hydroxyurea) under Medicaid Programs is now available in 37 states, with 13 states including it on their Preferred Drug List, while 24 states offer it with limited, or no, restrictions. This important milestone for Medunik USA allows broader access to this essential medicine, benefiting patients suffering from sickle cell disease (SCD).

Siklos® has been used worldwide to treat SCD for over 15 years and was approved by the FDA for use in the USA in 2017. This medicine is the only hydroxyurea (HU)-based therapeutic option that offers both flexible dosing and administration, giving patients and caregivers more control over managing their care and shaping a treatment routine that works for them. Patients can choose the best way to take Siklos®, whether by swallowing it whole or split based on the dose, or dissolving it in a small amount of water.

Siklos® is the only FDA-approved dissolvable formulation of hydroxyurea that reduces painful crises and blood transfusions for sickle cell patients aged 2 years and older.   Siklos® has a BOXED WARNING regarding Low Blood Cell Count and Cancer. The most common side effects of Siklos® in children include: infections and low white blood cells, and in adults include: infections, headache, and dry skin.

"We are proud to see increased coverage for this important therapy, which represents a significant step forward in the standard of care for patients with sickle cell disease. Siklos® provides patients with options on how to best take their HU treatment," said Tanya Carro, Executive Vice President, U.S. Entities. "With fewer SCD treatment options currently available, it is even more important to empower patients to stay on therapy in a way that fits their lives. That's what drives long-term adherence and meaningful health outcomes."

Sickle cell anemia is the most common inherited blood disorder, resulting in the production of abnormal hemoglobin, known as hemoglobin-S, 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, may therefore, reduce quality of life^1,2. Most of those affected are of African ancestry; a minority are of Hispanic or southern European, Middle Eastern or Asian Indian descent³.

Committed to improving the lives of people living with rare disorders, Medunik USA strives to remove the logistical barriers and to broaden reimbursement pathways to empower patients with SCD and their caregivers. Medunik USA supports patient access by offering a robust assistance program that includes educational resources and savings programs.
