Clinical Trial Trends: Rare CNS

Clinical Trial Trends: Rare CNS

In rare disease research, central nervous system (CNS) issues are very common, making up some 50% of all rare diseases on record. However, the field is extremely heterogeneous. Take autoimmune demyelinating diseases, for example. While they do all impact organ-specific immunity, that’s really the limit of their commonality. Each rare autoimmune demyelinating issue has a unique pathology with its own functional consequences. For example, Multiple Sclerosis (MS) is fundamentally different from rare MS variants and requires a different approach to diagnosis and disease management. 

In this article, we will examine the rare CNS research landscape, exploring the clinical trial pipeline across phases and mechanisms using research from Citeline. We will conclude by outlining Precision for Medicine’s past and current experience in the space.
