Branaplam (development codes LMI070 and NVS-SM1) is an experimental drug being developed by Novartis to treat spinal muscular atrophy (SMA). It is a pyridazine derivative that works by increasing the amount of functional survival of motor neuron protein produced by the SMN2 gene through modifying its splicing pattern.[1][2]

As of July 2019, branaplam is in a phase-II clinical trial in children with SMA type 1.[3][4][5]

In October 2020, Novartis stated that the running trials for SMA showed that branaplam lowers the level of huntingtin protein as well. Lowering huntingtin protein is one of the major approaches researched by different companies to cure Huntington's disease. U.S. Food and Drug Administration granted an orphan drug status to branaplam for treatment of Huntington’s disease, and Novartis announced that they will set up trials for HD patients in 2021.[6] In December 2021, Branaplam garnered Fast Track breakthrough designation by the FDA towards a Phase IIb study in adult patients with early-stage HD manifestaion.[7][8]
