5 Most Promising Companies offering hope to patients with Niemann-Pick Type C

28 Aug 5 Most Promising Companies offering hope to patients with Niemann-Pick Type C

Niemann–Pick is a rare autosomal recessive inherited disease that is characterized by excessive accumulation of cholesterol and lipids in cells, leading to apoptosis and neural degeneration. The disease affects numerous body parts such as the brain, nerves, liver, spleen, bone marrow and lungs. Those suffering from the disease suffer from lack of coordination, dystonia; sleep disturbances, difficult in eating and swallowing and frequent bouts of pneumonia.

The disease is categorized into three types based on when it manifests and the severity of the symptoms, Type A and B are caused due to a malfunctioning enzyme called sphingomyelinase. Type C is a variant of the disease, where a patient may not exhibit or experience any symptoms until adulthood. The process of diagnosis involves testing blood samples or a skin biopsy, Magnetic Image Resonance (MRI), eye exam, genetic and prenatal testing.

There is no cure available to treat this condition, with treatment being limited to improving or delaying the onset of symptoms. Physiotherapy plays a crucial role in helping maintain mobility and hence is a recommended course of action. The only FDA approved drug for treatment of NPC, Miglustat (Zavesca), has demonstrated the ability to improve neurological symptoms; however it is known to cause tremors, gastrointestinal disturbances and spermatogenesis and has an adverse impact on patients with renal or hepatic impairment.

According to an estimate by the NIH, Niemann-Pick Type A and B affect 1 in 250,000 individuals, making it an extremely rare disease; however some races and ethnicities are more susceptible to this disorder, such as the Ashkenazi (eastern and central European people of Jewish Descent) who has 1 in 40000 chances of developing this condition. In addition Type C1 of the disease affects 1 in 150,000 individuals, accounting for over 95 percent of the diagnosis.

We take a look at some companies that are engaged in extensive research efforts to uncover a cure for this rare disorder.

Arimoclomol, its lead drug candidate, is undergoing clinical studies for four indications namely Niemann-Pick disease Type C, Gaucher disease, sporadic Inclusion Body Myositis, and Amyotrophic Lateral Sclerosis. The drug candidate can improve the production of heat-shock proteins (HSPs), which can rescue defective misfolded proteins, clear protein aggregates, and improve the function of lysosomes. The Core technology of the company is based on the cell-protective properties of the heat-shock response. They act as molecular chaperones for stressed cells, by re-folding misfolded proteins and directing ‘terminally’ misfolded protein to be broken down.

There are numerous kinds of HSPs; however Orphazyme uses the HSP70 as the key parameter to measure activity of its drug candidates, as it has been found responsible for offering protection against the formation of protein aggregates in neurodegenerative diseases including sIBM and ALS. In addition, it is also useful in lysosomal sphingolipid breakdown, which promotes metabolism of stored lipids and prevents their accumulation.

NPC-001, an observation trail, demonstrated slowing of disease progression rate and led to identification of potential disease biomarkers for Niemann-Pick disease Type C (NPC). The study has completed a Phase II/III trial enrollment, with topline results being expected in Q1 2019. The company is all set to file for a NDA in H1 2020, with potential approval in H2 2020.
