What is it?

In collaboration with researchers, nusinersen was developed by Ionis Pharmaceuticals and Biogen Idec. Marketed as SpinrazaTM, it was the first potentially disease-modifying treatment available in the UK for 5q SMA, which includes SMA Type 1, 2 3 and 4. It is an antisense oligonucleotide designed to modify the product of the SMN2 “backup” gene to produce more functional SMN protein.

You can read how the original scientists who worked on it won the 2019 Breakthrough prize (the “Oscars for science”) here; how Biogen won the UK Prix Galien award for it, here.

How it Works

You can read more and watch Cold Spring Harbor laboratory’s video about how it works, here.

UK Access Now

The NHS now funds this treatment for all children and adults for whom it is clinically safe and potentially beneficial.

Treatment Information Leaflets

These leaflets aim to provide a summary for anyone considering the possibility of treatment for their child, or themselves. Read More.

Clinical Trial Results and 'Real World' Use

Clinical trials have been with infants and children who have SMA Types 1, 2 or 3. There have not yet been any clinical 
trials with anyone with adult onset SMA Type 4.

Our Research Correspondents have tracked the results as they have been released. You can read these updates 
here. They also summarise published ‘real world’ studies, 

Global Access

On 23rd December 2016, the US Food and Drug Administration (FDA) approved the use of nusinersen under its brand name SpinrazaTM for both children and adults with SMA Types 1, 2 or 3 SMA.

On 1st June 2017, the European Commission approved the treatment for those with 5q SMA. Their full report is here. Since then, access in each country has been, and still is being, decided by their regulatory authorities.
