Zevra Therapeutics, Inc. a rare disease therapeutics company, announced it resubmitted its New Drug Application for arimoclomol, an investigational therapeutic candidate for the treatment of Niemann-Pick disease type C to the U.S. Food and Drug Administration on December 22, 2023.
CELEBRATION, Fla., Dec. 27, 2023 (GLOBE NEWSWIRE) -- Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) a rare disease therapeutics company, today announced it resubmitted its New Drug Application (NDA) for arimoclomol, an investigational therapeutic candidate for the treatment of Niemann-Pick disease type C (NPC) to the U.S. Food and Drug Administration (FDA) on December 22, 2023. Based on standard NDA resubmission review timelines, an acknowledgment letter from the FDA that the resubmission is complete and setting the PDUFA date is expected within 30 days. Zevra expects the NDA to be classified as a Class II submission which would be subject to a review period by the FDA within six months from the date of submission.
“The Zevra team has worked diligently to deliver a high quality and thorough resubmission of the NDA for arimoclomol following multiple interactions with the FDA and after incorporating direction from the agency,” said Neil McFarlane, President and Chief Executive Officer of Zevra. “We continue to accelerate our launch preparations in anticipation of FDA approval, and believe we are one step closer to getting arimoclomol into the hands of patients who are seeking a treatment.”
“Zevra has engaged with the advocacy community, elevating the patient voice throughout arimoclomol’s development process,” said Daniel Gallo, Ph.D., Zevra’s Senior Vice President of Medical Affairs and Advocacy. “The advocacy community’s input has been instrumental in building awareness of the need for approved treatments that address the unmet needs of individuals and their caregivers living with this debilitating condition.”
Zevra believes it has addressed the issues previously raised by the FDA in the complete response letter by providing additional evidence to support the use of the Niemann-Pick type C Clinical Severity Scale (NPCCSS) and, conducting additional studies used to support the potential mechanism of action. Additionally, new data included in the resubmission comes from multiple non-clinical studies, natural history comparisons, real-world data generated from the ongoing early access programs in the United States and the European Union, as well as data from the four-year open-label extension of the Phase 2/3 clinical trial (NCT02612129). Results from this open-label trial suggest that arimoclomol reduces the long-term progression of NPC.
Arimoclomol has been evaluated in a total of 21 studies across a range of Phase 1, 2 or 3 clinical trials evaluating its safety and efficacy across more than 600 subjects in NPC, other disease or healthy subjects. The primary efficacy trial evaluating arimoclomol for the treatment of NPC was a Phase 2/3 double-blind, placebo-controlled trial (CT-ORZY-NPC-002) of arimoclomol in 50 patients with NPC.
About Niemann-Pick disease type C:
Niemann-Pick disease type C (NPC) is an ultra-rare, genetic, progressive and fatal neurological disease caused by mutations in the NPC1 or NPC2 genes. Both genes encode proteins, located in intracellular compartments called lysosomes, which are essential in the transport and metabolism of lipids. Mutations in either of these NPC genes result in a reduced amount of NPC1 or NPC2 protein causing lysosomal dysfunction due to accumulation of intracellular lipids and ultimately, if unchecked, cell death. Evidence suggests that arimoclomol improves lysosomal function within the cells, reducing the accumulation of lipids to delay and prevent cell death. NPC is an inherited disorder that affects both children and adults with varying ages of onset, rate of progression and presents differently in each person. NPC is characterized by visceral (internal organs) manifestations, including enlarged liver and spleen, neurological and psychiatric manifestations. Those living with NPC lose independence due to physical and cognitive limitations. Key neurological impairments are in speech, cognition, swallowing, ambulation, and fine motor skills. Disease progression is irreversible and can be fatal within months or take years to diagnose and advance.
