Name	L-Acetylleucine
Groups	approved investigational
Description	Levacetylleucine (L-acetylleucine) is a modified acetylated derivative of the amino acid [leucine]. The racemic (i.e. DL-) form has been available in France since 1957 for the treatment of vertigo.[A264439] Observational studies in patients with Niemann-Pick disease type C (NPC) suggested a beneficial symptomatic as well as neuroprotective disease-modifying effect of the DL-form of N-acetylleucine, after which animal studies showed that the L-enantiomer (i.e. levacetylleucine) has potential clinical benefits compared to the racemic mixture.[A264439] In September 2024, the FDA approved levacetylleucine for the treatment of select patients with NPC.[L51444]
