About foliglurax

Foliglurax is a small molecule, which works by stimulating a specific glutamatergic target (mGluR4) that activates a compensatory neuronal system in the brain. Pre-clinical studies have demonstrated positive effects in models of Parkinson’s disease. The aim is to treat the motor symptoms of Parkinson’s disease, such as resting tremor and dyskinesia.

About Parkinson’s disease

Parkinson’s disease is a devastating progressive neurological condition affecting around 6 million people worldwide. The disease is caused by the degeneration of dopaminergic brain cells. The main motoric symptoms are resting tremor, muscle rigidity and slowed movement (bradykinesia). Uncontrolled movements (dyskinesia) is a debilitating complication to levodopa use.

Current treatments aim to replace dopamine or to mimic its effects. Patients are administered with the dopamine precursor levodopa. This treatment provides adequate symptomatic relief initially, but over time, it loses efficacy as the disease progresses and patients experience serious debilitating complications, such as increased OFF time and dyskinesia.
