Cycle Pharmaceuticals Partners with Cardinal as the Logistic Provider for Nityr in U.S.

AUGUST 7, 2017

CAMBRIDGE, England, August 7, 2017 – Cycle Pharmaceuticals (“Cycle”) has selected Cardinal Health Inc (“Cardinal”) as the importer and distributor of its nitisinone tablets Nityr™ to Diplomat Pharmacy, Inc. Cycle and Cardinal have entered an agreement where Cardinal is the exclusive U.S. logistic provider.

Nityr™ has recently been approved by the U.S. Food and Drug Administration (FDA) for the treatment of Hereditary Tyrosinemia type-1 (HT‑1) in combination with dietary restriction of tyrosine and phenylalanine.

Bioequivalent to the current nitisinone capsule, Nityr™ is the first treatment for HT-1 that does not require refrigeration and can be administered with or without food. Nityr™ provides treatment for patients from infancy to adulthood and is available as an easy to swallow small tablet. Nityr™ can also be disintegrated and administered in an oral syringe – ideal for paediatric patients.

“Cardinal Health is a leading wholesaler, distributor and logistic operator in the U.S.. This partnership is consistent with our view of excellence of services and will strengthen the supply chain of Nityr™, securing the availability of our product for the HT-1 community.” said Philippe Di Ruzza, Director North America, Cycle Pharmaceuticals.

Available in three strengths, 2 mg, 5 mg and 10 mg, Nityr™ tablets are manufactured in Switzerland.

In clinical trials, Nityr™ tablets have an established safety profile with warnings and precautions as follows:

  1. Elevated Plasma Tyrosine Levels, Ocular Symptoms, Developmental Delay and Hyperkeratotic Plaques: Inadequate restriction of tyrosine and phenylalanine intake can lead to elevations in plasma tyrosine, which at levels above 500 micromol/L can result in symptoms, intellectual disability and developmental delay or painful hyperkeratotic plaques on the soles and palms; do not adjust the dosage of Nityr™ in order to lower the plasma tyrosine concentration. Obtain slit-lamp examination prior to treatment and re-examination if symptoms develop. Assess plasma tyrosine levels in patients with an abrupt change in neurologic status.
  2. Leukopenia and Severe Thrombocytopenia: Monitor platelet and white blood cell counts.

There are no contraindications for Nityr™ tablets, however, you should consult your Doctor prior to taking this medication. For full prescribing information on Nityr™, please visit

About HT-1

Hereditary Tyrosinemia type-1 (HT-1) is a rare and serious inherited metabolic disease caused by the inability to metabolise the amino acid tyrosine. Left untreated, HT-1 can cause hepatic, renal and peripheral nerve damage. HT-1 affects at least 1 in 100,000 patients worldwide, with approximately 150 patients in the United States.

About Cycle Pharmaceuticals, the commitment to HT-1 and Nityr

Cycle Pharmaceuticals is committed to changing the way that HT-1 is treated and managed around the world. Cycle Pharmaceuticals has worked for more than four years closely with physicians and patient groups to reduce the impact that HT-1 treatment has on patients’ lives. Nityr™ is the first formulation of nitisinone treatment that does not require refrigeration (removing the need of a cold chain transportation and storage) and can be taken with or without food, representing a significant improvement from previous treatments for patients and caregivers.

Nityr™ should be taken in conjunction with a controlled diet and under the supervision of a healthcare professional.
