NITYR (nitisinone) Tablets for Tyrosinaemia Type 1 receives Marketing Authorization in New Zealand

MELBOURNE, Australia, March 15th, 2021 –Cycle Pharmaceuticals Ltd. and Orpharma NZ Ltd. are pleased to announce that on 19th January 2021 they have received the Marketing Authorization for NITYR™ (nitisinone) Tablets by the New Zealand Medicines and Medical Devices Safety Authority (MEDSAFE). NITYR is indicated for the treatment of patients with Hereditary Tyrosinaemia type 1 (HT-1) in combination with dietary restriction of tyrosine and phenylalanine.

HT-1 is an ultra-rare genetic disease that can cause hepatic, renal and neurological complications. In most cases, if left untreated, the disease is fatal. The current number of patients with this condition in New Zealand is estimated at 3-4 patients.

New Zealand’s Pharmaceutical Management Agency (PHARMAC) Rare Disorders Subcommittee made a decision to recommend funding of nitisinone with a high priority in 2019. A final decision is yet to be made by New Zealand’s Pharmacology and Therapeutics Advisory Committee (PTAC).

“This approval is part of the successful global roll out plan for NITYRTM, to ensure that HT-1 patients worldwide will have the opportunity to benefit from its unique characteristics. We look forward to continuing the work we started with Orpharma in Australia and being able to bring NITYR™ to patients in New Zealand” says Antonio Benedetti, CEO of Cycle.

NITYR™ was developed by Cycle Pharmaceuticals  Ltd. after many years of research and development to find an alternative formulation to ORFADIN* (nitisinone) Capsules. NITYR™ is clinically proven to be bioequivalent to ORFADIN1; has an improved formulation allowing it to be stored at room temperature and administered with or without food. NITYR™ tablets are small and tasteless, allowing for ease of swallowing, and are available in 2, 5 and 10 mg strengths. NITYR™ can be disintegrated in water and administered using an oral syringe, the preparation can be stored for up to 24 hours, allowing NITYR™ to be used by patients of any age.
