A Rare Disease Drug Developer Tries to Earn Its Stripes

Zevra Therapeutics, formerly KemPharm, rebranded itself in early 2023 following the acquisition of the experimental therapy arimoclomol for the rare lysosomal storage disorder Niemann Pick disease type C. Zevra is Greek for “zebra,” a symbol of rare disease. The company subsequently built out its rare disease pipeline through the acquisition of Acer Therapeutics in November 2023. An FDA decision on arimoclomol is due by the end of September. We spoke to Neil McFarlane, president and CEO of Zevra Therapeutics, about Niemann Pick disease type C, the FDA’s upcoming decision on whether to approve the drug, and its broader efforts to build itself into a rare disease therapeutics company.
