Description

LMI-070 is an experimental compound being developed by Novartis Pharma as a treatment for spinal muscular atrophy (SMA). It is a small-molecule drug which modifies alternative splicing of the SMN2 gene, bringing about increased levels of SMN protein. LMI-070 originated from a high-throughput phenotypic screening hit, pyridazine 2, and evolved via multiparameter lead optimization. In a severe mouse SMA model, LMI-070 treatment increased full-length SMN RNA and protein levels, and extended survival. LMI-070 is taken orally, usually in a liquid form once a week. It is in phase II clinical trial.
