Nusinersen is a Antisense Oligonucleotide owned by Biogen, and is involved in 18 clinical trials, of which 8 were completed, 9 are ongoing, and 1 is planned.

Nusinersen is SMN2 gene activator. ISIS-SMNRx compensates for the defect by promoting the production of functional SMN protein. Spinal muscular atrophy is caused by a loss or defect in the survival motor SMN1 gene leading to a decrease in the protein SMN. SMN1 gene produces functional SMN protein in healthy humans. SMN2 gene produces a small amount of SMN protein. ISIS-SMNRx enables the SMN2 gene to produce more functional SMN protein by modulating a cellular process, splicing. The drug candidate keeps exon 7 in the RNA which leads to the production of functional SMN protein.

The revenue for Nusinersen is expected to reach a total of $14.5bn through 2038. This change impacts the valuation of this asset and is an important factor to understand the current value of the drug in a clinical process. View the complete picture with the Nusinersen NPV Report.

GlobalData

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

To create this model, GlobalData takes into account factors including patent law, known and projected regulatory approval processes, cash flows, drug margins and company expenses. Combining these data points with GlobalData’s world class analysis creates high value models that companies can use to help in evaluation processes for each drug or company.

The rNPV method integrates the probability of a drug reaching a clinical stage into the cash flow at that time, which provides a more accurate valuation, as it considers the probability that the drug never makes it through the clinical pathway to commercialization. GlobalData’s rNPV model uses proprietary likelihood of approval (LoA) and phase transition success rate (PTSR) data for the indication in the highest development stage, which can be found on GlobalData’s Pharmaceutical Intelligence Center.
