The U.S. Food and Drug Administration today approved Xadago (safinamide) tablets as an add-on treatment for patients with Parkinson’s disease who are currently taking levodopa/carbidopa and experiencing “off” episodes. An “off” episode is a time when a patient’s medications are not working well, causing an increase in Parkinson’s symptoms, such as tremor and difficulty walking.

March 21, 2017, Release

The U.S. Food and Drug Administration today approved Xadago (safinamide) tablets as an add-on treatment for patients with Parkinson’s disease who are currently taking levodopa/carbidopa and experiencing “off” episodes. An “off” episode is a time when a patient’s medications are not working well, causing an increase in Parkinson’s symptoms, such as tremor and difficulty walking.

“Parkinson’s is a relentless disease without a cure,” said Eric Bastings, M.D., deputy director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research. “We are committed to helping make additional treatments for Parkinson’s disease available to patients.”

An estimated 50,000 Americans are diagnosed with Parkinson’s disease each year, according to the National Institutes of Health, and about one million Americans have the condition. The neurological disorder typically occurs in people over age 60, though it can occur earlier, when cells in the brain that produce a chemical called dopamine become impaired or die. Dopamine helps transmit signals between the areas of the brain that produce smooth, purposeful movement – such as eating, writing, and shaving. Early symptoms of the disease are subtle and occur gradually. In some people, Parkinson’s disease progresses more quickly than in others.

The efficacy of Xadago in treating Parkinson’s disease was shown in a clinical trial of 645 participants who were also taking levodopa and were experiencing “off” time. Those receiving Xadago experienced more beneficial “on” time, a time when Parkinson’s symptoms are reduced, without troublesome uncontrolled involuntary movement (dyskinesia), compared to those receiving a placebo. The increase in “on” time was accompanied by a reduction in “off” time and better scores on a measure of motor function assessed during “on” time than before treatment.

In another clinical trial of 549 participants, the participants adding Xadago to their levodopa treatment had more “on” time without troublesome uncontrolled involuntary movement compared to those taking a placebo, and also had better scores on a measure of motor function assessed during “on” time than before treatment.

Certain patients should not take Xadago. These include patients who have severe liver problems, or who take a medicine used to treat a cough or cold called dextromethorphan. It also should not be taken by patients who take another medicine called a monoamine oxidase inhibitor (MAOI) because it may cause a sudden severe increase in blood pressure, or by those who take an opioid drug, St. John’s wort, certain antidepressants (such as serotonin-norepinephrine reuptake inhibitors, tricyclics, tetracyclics, and triazolopyridines), or cyclobenzaprine, because it may cause a life-threatening reaction called serotonin syndrome.

The most common adverse reactions observed in patients taking Xadago were uncontrolled involuntary movement, falls, nausea, and trouble sleeping or falling asleep (insomnia).

Serious, but less common, risks include the following: exacerbated high blood pressure (hypertension); serotonin syndrome when used with MAOIs, antidepressants, or opioid drugs; falling asleep during activities of daily living; hallucinations and psychotic behavior; problems with impulse control/compulsive behaviors; withdrawal-emergent hyperpyrexia (fever) and confusion; and retinal pathology.

The FDA granted approval of Xadago to Newron Pharmaceuticals.

Safinamide (INN; brand name Xadago) is a drug indicated for the treatment of Parkinson’s disease with monoamine oxidase B inhibiting and other methods of action.[2] It was approved in Europe in February 2015,[3] and in the United States on March 21, 2017[4]. It has also been tested for the use in patients with restless legs syndrome (RLS), but no study results have been published.

Medical uses

Safinamide has been approved by the European Medicines Agency for the treatment of adult patients with idiopathic Parkinson’s disease as add-on therapy to a stable dose of levodopa (L-dopa) alone or in combination with other Parkinson drugs in patients with mid-to-late-stage fluctuating disease.[5]

Contraindications

Safinamide is contraindicated in patients with severe liver impairment, with albinism, retinitis pigmentosa, severe diabetic neuropathy, uveitis and other disorders of the retina. Combination with other monoamine oxidase (MAO) inhibitors and pethidine is also contraindicated.[6]

Adverse effects

Common adverse events in clinical trials (in more than 1% of patients) included nausea, dizziness, tiredness, sleeplessness, orthostatic hypotension (low blood pressure), and headache. There was no significant difference in the occurrence of these effects between safinamide and placebo treated patients.[6][7]

In experiments with rats (but not in those with monkeys), retinopathies have been observed.[1][8]

Overdose

Expected overdose effects are hypertension (high blood pressure), orthostatic hypotension, hallucinations, psychomotor agitation, nausea, vomiting, and dyskinesia. In studies, a singe patient was suspected to have overdosed for a month; symptoms were confusion, drowsiness and mydriasis (dilation of the pupils) and subsided completely after the drug was discontinued. No specific antidote is available.[6]

Interactions

As a MAO inhibitor, safinamide can theoretically cause hypertensive crises, serotonin syndrome and other severe side effects when combined with other MAO inhibitors or with drugs that are known to interact with MAO inhibitors, such as pethidine, dextromethorphan, selective serotonin reuptake inhibitors (SSRIs), serotonin–noradrenaline reuptake inhibitors (SNRIs), tricyclic and tetracyclic antidepressants. An interaction with tyramine, a substance found in various foods, could be expected by the same reasoning but has been excluded in studies.[6]

Another theoretical interaction is with drugs with affinity to the transporter protein ABCG2 (also known as BCRP), such as pitavastatin, pravastatin, ciprofloxacin, methotrexat, and diclofenac; a study with the latter has shown no clinical relevance.[9] A study testing possible interactions with amidase inhibitors is part of the post-authorisation development plan.[1] There are no relevant interactions related to cytochrome P450 (CYP) liver enzymes, although one inactivation pathway of safinamide seems to be mediated by CYP3A4.[6]

Pharmacology

Mechanisms of action

Like the older antiparkinson drugs selegiline and rasagiline, safinamide is a selective monoamine oxidase B inhibitor, reducing degradation of dopamine; in contrast to the other two, its action is reversible. Safinamide also inhibits glutamate release[7][10] and dopamine reuptake.[11] Additionally, it blocks sodium and calcium channels,[10][12] the relevance of which for its antiparkinson action is however unknown.[6]

Pharmacokinetics

Safinamide is absorbed quickly and nearly completely from the gut and reaches highest blood plasma concentrations after 1.8 to 2.8 hours. There is no relevant first-pass metabolism; total bioavailability is 95%. The substance is bound to plasma proteins to 88–90%.[6]

The metabolism is not well understood. The principal step is mediated by amidases which have not been identified, and produces safinamide acid (NW-1153). Other relevant metabolites are O-debenzylated safinamide (NW-1199),[9] the N-dealkylated amine which is then oxidized to a carboxylic acid (NW-1689), and the glucuronide of the latter.[6][13] In tests with liver microsomes, dealkylation seemed to be mediated by CYP3A4, but other CYP enzymes appear to be involved as well. Safinamide acid binds to the organic anion transporter 3 (OAT3), but this has probably no clinical relevance. Safinamide itself transiently binds to ABCG2. No other transporter affinities have been found in preliminary studies.[6]

Safinamide is eliminated, mainly (>90%) in form of its metabolites, via the kidney, with an elimination half-life of 20 to 30 hours. Only 1.5% are found in the stool.[6]

Metabolism pathways of safinamide.[9][13] Enzymes: CYP = cytochrome P450, MAO-A = monoamine oxidase A, ALDH = aldehyde dehydrogenases, UGT = UDP-glucuronosyltransferases. Gluc = acyl glucuronide.

History

The compound was originally discovered at Farmitalia-Carlo Erba, which was acquired by Pharmacia in 1993. In 1995, Pharmacia merged with Upjohn. Safinamide was first disclosed in 1998.[14] In the course of a major restructuring in the same year, all rights for safinamide were transferred to the newly formed company Newron Pharmaceuticals, which developed the drug until it was sold to Merck KGaA in 2006.[15]

In 2007, a Phase III clinical trial was started, scheduled to run until 2011.[16] In October 2011 Merck, now Merck-Serono, announced that they would give all rights to develop the compound back to Newron because they wanted to prioritise other projects and had corrected their estimates for safinamide’s market potential downwards.[17]

The US Food and Drug Administration (FDA) refused to file Newron’s application in 2014 on formal grounds.[18] Newron re-applied in December 2014.[19] In spring 2015, the European Medicines Agency (EMA) approved the drug. Safinamide is the first antiparkinson medication to be approved for ten years.[8]

Research

Potential additional uses might be restless legs syndrome (RLS) and epilepsy.[20] They were being tested in Phase II trials in 2008, but no results are available.

Parkinson’s disease (PD) is a progressive neurodegenerative disease characterized by bradykinesia, rigidity, resting tremor, and ataxia. These symptoms are caused by decreased dopamine release in the striatum. Clinically, PD is defined by presence of Lewy bodies, intracellular neuronal inclusions in the substantia nigra and at other sites in the brain. Estimated prevalence of this disease is 100 to 200 per 100,000 population including males and females across the entire age group. Current treatment for PD comprises dopaminergic medications that include levodopa, dopamine agonists (DAs), monoamine oxidase-B (MAO-B) inhibitors. Figure 1 provides few examples of pharmaceutically important benzyloxy-benzylamine derivatives. Many of these benzyl oxy-benzylamines with various amine functions were studied and has been patented as sodium channel blockers. Among them, safinamide ((5)-N2– {4-[3- fluorobenzyl)oxy] benzyl}- alaninamide methanesulfonate) is a noted example which is under phase III clinical trials for treatment of Parkinson’s disease. Its mechanism of action is manifold which comprise MAO-B and dopamine uptake inhibition. Further, safinamide is believed to block voltage-dependent sodium channels, modulates calcium channels and reduction of glutamate release in the central nervous system. WOl 998003472 discloses serinamide, glycinamide, alaninamide and phenylalaninamide derivatives of a compound (I). These compounds (I) are useful for the treatment of neurological diseases.

EP2474521 discloses high purity degree (S)-2-[4-(3-fluorobenzyloxy)- benzylamino]propanamide (safinamide) or (S)-2-[4-(2-fluorobenzyloxy)- benzylamino]propanamide (ralfinamide) or a salt thereof with a pharmaceutically acceptable acid with a content of the respective impurity (S)-2-[3-(3-fluorobenzyl)-4-(3- fluorobenzyloxy)-benzylamino]propanamide or (S)-2-[3-(2-fluorobenzyl)-4-(2- fluorobenzyloxy)-benzylamino]propanamide.

US2009149544 relates to novel alpha- aminoamide derivatives, their pharmaceutically acceptable salts, solvates, and hydrates thereof. The application also provides compositions comprising a compound and the use of such compositions in methods of treating diseases and conditions that are beneficially treated by administering an inhibitor of monoamine oxidase type B (MAO-B) and/or a sodium (Na.sup.+) channel blocker, and/or a calcium (Ca.sup.2+) channel modulator.

The strategy employed in the art to prepare benzyloxy-benzylamine derivatives including safinamide or its analogue ralfinamide is chiral pool approach starting from L-alaniriamide and reductively aminating with 4-(3-fluorobenzyloxy) benzaldehyde. Although this method is very simple and straightforward, it suffers from several serious drawbacks, such as need to use toxic reagents such as sodium cyanoborohydride and further formation of toxic by-products such as hydrogen cyanide and sodium cyanide and other toxic impurities in large-scale production Importantly, the possibility of generating a range of safinamide analogues by means of the chiral-pool approach is limited in terms of the structure and stereochemistry of the products because of inadequacies in the availability of D-alaninamide and its analogues

Hence, the developments of newer methods for the preparation of compounds of formula (I) comprising safinamide and related analogues are highly desirable

N2-{4-[(3-fluorobenzyl)oxy]benzyl}-L-alaninamide

Newron Pharmaceuticals and fellow Italy-headquartered partner Zambon have filed their investigational Parkinson’s disease treatment safinamide with regulators in the USA.

The submission to the US Food and Drug Administration is for safinamide as add-on therapy in early and mid-to late stage PD patients. Newron said the filing was based on “completion of activities agreed upon during meetings” with the FDA, noting that a marketing authorisation application was submitted to the European Medicines Agency in December.

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 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.[3]

Potential additional uses might be restless legs syndrome (RLS) and epilepsy.[4] 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.[5]

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][5] It also seems to inhibit dopamine reuptake.[7] Additionally, safinamide blocks sodium and calcium channels.[6]
