Copenhagen – October 31, 2021 – Orphazyme A/S (ORPHA.CO; ORPH), a late-stage biopharmaceutical company, today provides an update on the regulatory status in the United States of its investigational product arimoclomol for Niemann-Pick disease type C (NPC) following a recently held Type A meeting with the U.S. Food and Drug Administration (FDA).

The Company had a collaborative dialogue with the FDA during the Type A meeting, which was held in order to discuss the key topics in the Complete Response Letter (CRL) issued by the FDA in June 2021. The CRL was issued based on the need for additional confirmatory evidence as well as additional qualitative and quantitative evidence to further substantiate the validity of the 5-domain NPC Clinical Severity Scale (NPCCSS), in particular the swallow domain, in the context of a lack of significant findings when using the FDA’s preferred and recommended statistical approach.

The Type A meeting resulted in the following take-aways:

  • The FDA recommended that the Company submit additional data, information, and analyses to address certain topics in the CRL and engage in further interactions with the FDA to identify a pathway to resubmission.
  • The FDA concurred with the Company’s proposal to remove the cognition domain from the NPCCSS endpoint, with the result that the primary endpoint is permitted to be recalculated using the 4-domain NPCCSS, subject to the submission of additional requested information which the Company intends to provide. To bolster the confirmatory evidence already submitted, the FDA affirmed that it would require additional in vivo or pharmacodynamic (PD)/pharmacokinetic (PK) data; the Company is considering the optimal path forward to address the FDA’s requests.

About Niemann-Pick disease type C
Niemann-Pick disease type C (NPC) is a rare, genetic, progressively debilitating, and often fatal neurodegenerative disease. It belongs to a family known as lysosomal storage disorders and is caused by mutations leading to defective NPC protein. As a consequence, lipids that are normally cleared by the lysosome accumulate in tissues and organs, including the brain, and drive the disease pathology. We estimate the incidence of NPC to be one in 100,000 live births and the number of NPC patients in the United States and in Europe to be approximately 1,800 individuals. There are no approved treatments for NPC in the U.S.

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, and has now been studied in 10 Phase 1, four Phase 2, and three pivotal Phase 2/3 trials. Arimoclomol has received Orphan Drug Designation (ODD) for NPC in the US and EU. Arimoclomol has received Fast-Track Designation (FTD), Breakthrough Therapy Designation (BTD), and Rare Pediatric Disease Designation (RPDD) from the U.S. Food and Drug Administration (FDA) for NPC. On June 17, 2021, Orphazyme received a Complete Response Letter from the FDA regarding its New Drug Application for arimoclomol for the treatment of NPC. A marketing authorization application (MAA) for arimoclomol in NPC has been filed with the European Medicines Agency and is under review.
