Safinamide in Idiopathic Parkinson's Disease (IPD) With Motor Fluctuations, as add-on to Levodopa
A Phase 3 study testing Safinimide 50-100 mg/day in people with Idiopathic Parkinson's Disease, run by Newron Pharmaceuticals SPA at 121 sites in 21 countries.
Trial summary
Parkinson's Disease is a major neurodegenerative disorder in which there is a progressive loss of dopamine-containing neurons. The understanding that PD is a syndrome of dopamine (DA) deficiency led to the introduction in the clinical practice of L-dopa, a precursor of DA that crosses the blood brain barrier, and also… Read more about this study

About this study
Official title: A Phase III, Double-blind, Placebo-controlled, Randomised Trial to Determine the Efficacy and Safety of a Dose Range of 50 to 100 mg/Day of Safinamide, as add-on Therapy, in Subjects With Idiopathic Parkinson's Disease With Motor Fluctuations, Treated With a Stable Dose of Levodopa and Who May be Receiving Concomitant Treatment With Stable Doses of a Dopamine Agonist, an Anticholinergic and/or Amantadine
Parkinson's Disease is a major neurodegenerative disorder in which there is a progressive loss of dopamine-containing neurons. The understanding that PD is a syndrome of dopamine (DA) deficiency led to the introduction in the clinical practice of L-dopa, a precursor of DA that crosses the blood brain barrier, and also to the use of selective inhibitors of MAO-B, the major DA metabolising enzyme in man.
Safinamide is an inhibitor of MAO-B. This is a phase III trial to evaluate the efficacy and safety of safinamide (50 and 100 mg p.o. q.a.m.) compared to placebo as add-on therapy to a stable dose to levodopa in subjects with advance idiopathic Parkinson's Disease.
The principal efficacy measure is the increase in mean daily "on" time during the 18-hr diary recording period.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Parkinson's Disease is a major neurodegenerative disorder in which there is a progressive loss of dopamine-containing neurons. The understanding that PD is a syndrome of dopamine (DA) deficiency led to the introduction in the clinical practice of L-dopa, a precursor of DA that crosses the blood brain barrier, and also to the use of selective inhibitors of MAO-B, the major DA metabolising enzyme in man.
Safinamide is an inhibitor of MAO-B. This is a phase III trial to evaluate the efficacy and safety of safinamide (50 and 100 mg p.o. q.a.m.) compared to placebo as add-on therapy to a stable dose to levodopa in subjects with advance idiopathic Parkinson's Disease.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Safinimide 50-100 mg/day in people with Idiopathic Parkinson's Disease, run by Newron Pharmaceuticals SPA at 121 sites in 21 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 121 sites in United States, Germany, Hungary, India, Belgium and 16 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evaluate the change from baseline to W24 in daily "on" time ("on" time without dyskinesia plus "on" time with minor dyskinesia) (time frame: 24 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00627640, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Mar 2013; AzTrials last refreshed its copy on 8 Nov 2026.
