WAVE Life Sciences Ltd. announced that its lead candidate WVE-120101, which is being investigated for the treatment of Huntington’s disease (HD), has received Orphan Drug Designation by the U.S. Food and Drug Administration (FDA). WVE-120101 targets rs362307, a Single Nucleotide Polymorphism (SNP) that is associated with the disease-causing mutation in the huntingtin (HTT) gene. WAVE’s approach enables selective silencing of the disease-causing HTT allele, while leaving the healthy HTT allele to produce normally functioning protein.
