·There are currently no US FDA-approved products for NPC
·Orphazyme plans to file arimoclomol in the US in H1 2020

COPENHAGEN, Denmark I November 19, 2019 I Orphazyme A/S (ticker: ORPHA.CO), a biopharmaceutical company dedicated to developing treatments for patients living with rare diseases, today announces that the US Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation for arimoclomol, an investigational drug for the treatment of Niemann-Pick Disease Type C (NPC).

Kim Stratton, Chief Executive Officer at Orphazyme, commented, “We are delighted with FDA’s decision to grant Breakthrough Therapy Designation to arimoclomol for NPC. Arimoclomol has been shown to have a clinically meaningful effect on disease progression in NPC that is further supported by a biomarker effect indicating an effect on the biological underpinnings of the disease and a favorable safety and tolerability profile. We are committed to bringing this product to patients as soon as possible. Breakthrough Therapy Designation is designed to expedite the development and review of products for serious diseases with the direct involvement of senior staff and we look forward to working closely with the FDA to further advance arimoclomol. Our preparations for filing in the US are underway and we are on track to submit a New Drug Application in H1 2020.

About Breakthrough Therapy Designation
Breakthrough Therapy Designation is a program intended to expedite the development and review of drugs to treat serious or life-threatening diseases in cases where preliminary clinical evidence shows that the drug may provide substantial improvements over available therapy.

The Denmark-based company is listed on Nasdaq Copenhagen (ORPHA.CO). For more information, please visit www.orphazyme.com

About arimoclomol 
Arimoclomol is an investigational drug candidate that amplifies the production of heat-shock proteins (HSPs). HSPs can rescue defective misfolded proteins, clear protein aggregates, and improve the function of lysosomes. Arimoclomol is administered orally, crosses the blood brain barrier, and has been studied in seven Phase I and three Phase II trials. Arimoclomol is in clinical development for NPC, Gaucher disease, sIBM, and ALS.

About NPC
Niemann-Pick disease Type C (NPC) is a genetic, progressively debilitating, and often fatal neurovisceral disease. It belongs to a family know as lysosomal storage diseases and is caused by mutations leading to defective NPC protein. As a consequence, lipids that are normally cleared by the lysosome build-up in tissues and organs, including the brain, and drive the disease pathology. The estimated prevalence of NPC in the USA and Europe combined is 1,000-2,000. There are no approved treatments for NPC in the USA and only one approved product in Europe. Arimoclomol has been granted Orphan Drug Designation (EU and USA), Rare Pediatric Disease Designation (USA), and Fast Track designation (USA) for the treatment of NPC.
