Targeted Conditions

Spinraza is approved for the treatment of Spinal Muscular Atrophy (SMA) in both pediatric and adult patients. SMA is a rare genetic disorder characterized by loss of motor neurons in the spinal cord and brainstem, leading to progressive muscle weakness and atrophy.

Spinraza is indicated across all SMA types (Type 0–Type 4), including both pre-symptomatic and symptomatic patients.

Off-Label Usage

There are no widely accepted off-label uses for Spinraza due to its highly specific mechanism of action and indication.

Drug Classification Overview

Spinraza is an antisense oligonucleotide (ASO) that targets the SMN2 gene. It works by modifying the splicing of SMN2 pre-mRNA to promote the production of full-length survival motor neuron (SMN) protein — the key protein deficient in individuals with SMA.
