Technologies that include CRISPR-Cas9 gene editing and antisense oligonucleotides, or ASOs, have created the possibility to develop therapies with the goal of correcting or silencing specific defects in genes. Indeed, with the approval of therapies such as Spinraza in the treatment of SMA, it has been demonstrated that precision medicine is applicable in managing rare neurological diseases. Even advanced diagnosing tools such as whole-genome sequencing and NGS have been applied massively, making early and accurate diagnosis, while treatment is offered early.
Regulatory Support and Incentives is driving Revenue Growth for Rare Neurological Disease Treatment
Global regulatory frameworks have significantly fast-tracked therapies for rare neurological diseases. In the United States, that is the Orphan Drug Act, and, in Europe, that is through the Orphan Medicinal Product Regulation of the EMA, awarding pharmaceuticals with benefits in the form of tax credits, waived fees, and market exclusivity to encourage an investment of efforts in these drugs.
Since these incentives were put in place, orphan drug designations and approvals have multiplied, thus mitigating the financial risks of treatment development in relation to small patient populations. In addition, expediting approval pathways and breakthrough designations initiated by regulatory authorities have reduced time-to-market for innovatively designed treatments.
Rare neurological diseases received little attention during the past when the prevalence and cost of therapy development were pretty low. There are several other reasons that highlight regulatory frameworks have been the dominant forces behind these developments.
Particularly, the Orphan Drug Act of 1983 in the USA and the Orphan Medicinal Product Regulation of the European Medicines Agency, initiated in 2000, have set the grounds by providing the pharmaceutical companies with financial and operational incentives.
As far as this matter is concerned, these frameworks alleviate the difficulties experienced while treating smaller populations of patients while mechanisms are developed that reduce economic risks associated with the development of such therapies for rare diseases.
Emerging Applications of Gene Therapy is Creating Opportunities in the Market
Gene therapy opens a whole new window of opportunities in the treatment of rare neurological disorders, namely to attack the underlying causes of the conditions.
