Safinamide (EMD 1195686) is a candidate drug against Parkinson's disease with multiple methods of action.[1] In 2007, a Phase III clinical trial was started. It was scheduled to run until 2011.[2] The compound was originally discovered at Farmitalia-Carlo Erba [3] and developed by Newron Pharmaceuticals, which sold the rights to Merck-Serono in 2006. In October 2011 Merck-Serono announced that they would give all rights to develop the compound back to Newron.[4]

Potential additional uses might be restless legs syndrome (RLS) and epilepsy.[5] They were being tested in Phase II trials in 2008, but no results are available.

Adverse effects

Common adverse events in clinical trials were nausea, dizziness, tiredness, headache and backache. There was no significant difference in the occurrence of these effects between safinamide and placebo treated patients.[6]

Methods of action

Parkinson and RLS relevant mechanisms

Safinamide is a reversible and selective monoamine oxidase B inhibitor, reducing degradation of dopamine, and a glutamate release inhibitor.[6][7] It also seems to inhibit dopamine reuptake.[8] Additionally, safinamide blocks sodium and calcium channels.[7][9]
