Pheburane® (sodium phenylbutyrate) coverage to reach ~80% of commercially insured US patients by January 1st, 2024


PRINCETON, N.J., Oct. 26, 2023 (GLOBE NEWSWIRE) -- Medunik USA (member of Duchesnay Pharmaceutical Group, an international company selected in the Government of Canada's first Global Hypergrowth Project) is pleased to announce that as of January 1st, 2024, Pheburane® (sodium phenylbutyrate) will be covered by commercial plans representing ~80% of the US population. Working tirelessly to ease access to Pheburane® for Americans living with certain urea cycle disorders (UCDs), Medunik USA is continually expanding its network of governmental and private insurers covering Pheburane®.

Pheburane® is indicated as adjunctive therapy to standard of care, which includes dietary management, for the chronic management of adult and pediatric patients with UCDs involving deficiencies of carbamylphosphate synthetase (CPS), ornithine transcarbamylase (OTC) or argininosuccinate synthetase (AS). Pheburane® is not indicated for the treatment of acute hyperammonemia which can be life-threatening and requires emergency medical treatment. The most common side effects associated with sodium phenylbutyrate are menstrual dysfunction, decreased appetite, body odor and bad taste or taste aversion.1

Medunik USA has provided access to Pheburane® for Americans with certain UCDs since September 2022 and offers it at a discount to other therapies: one-third of the cost of RAVICTI® (glycerol phenylbutyrate)* and half the price of OLPRUVATM (sodium phenylbutyrate)*. As of October 2023, Pheburane® is covered by Medicaid programs with preferred status in 6 states and is also included on California Contract Drug List with no prior authorization required.

“Deciding to make our product available to UCD patients at a mere fraction of the price of our main competitors is not only a concrete demonstration of Medunik USA’s mission; it is also an illustration of the courage and patient-focused culture that drives our decisions” said Éric Gervais, President of Duchesnay Pharmaceutical Group. 

UCDs are rare, chronic, genetic conditions that can be fatal if left untreated, and can impact children from the time of birth. UCDs disrupt the body’s urea cycle, and therefore, the body is unable to remove the dangerous buildup of toxic chemicals, particularly ammonia, that are created from the digestion of protein. One in 35,000 people in the United States or about 28 per one million residents suffer from UCDs of different levels of severity.2

“In today’s complex and pressurized reality, it is every stakeholder’s responsibility to consider cost-effective treatment options when patients’ conditions permit, to maintain the durability of the healthcare ecosystem” said Tanya Carro, Executive Vice-President of Medunik USA.  “Medunik USA’s competitive pricing for Pheburane is a true testament of our commitment to provide Americans suffering from rare disease with access to orphan drugs.”

Pheburane® comes in the form of small oral pellets, about the size of grains of sugar, which are measured with its reusable, calibrated dosing spoon. It does not require any mixing or oral syringes and there is no weight restriction for patients. Pheburane® has a proven history in the treatment of UCDs on an international level, as it has been available in Europe since 2013, and in Canada since 2015.

Medunik USA offers Pheburane® through its UNIK Support Program – designed to support each unique patient. UNIK Support offers specialized services including a copay savings program, patient care liaison services, mail order pharmacy and other support services. Visit Pheburane.com for more information.

About urea cycle disorders (UCDs)

The main purpose of the Urea Cycle is to eliminate toxic ammonia from the blood and make urea, which is then excreted as urine. UCDs are rare genetic disorders that cause errors in this process, allowing high levels of ammonia, the key marker for UCDs, to build up in the bloodstream, potentially to dangerous and fatal levels. Ammonia is extremely toxic, particularly to the central nervous system. UCDs can cause catastrophic illness in newborns within 36 to 48 hours of birth despite the infants appearing normal, so they can be discharged from hospital before signs of UCDs develop. UCDs require lifelong monitoring and treatment.2

About Pheburane®

Pheburane® is not indicated for the treatment of acute hyperammonemia.1
