Effectiveness of alternative dose fingolimod for multiple sclerosis
Neurology. Clinical practice, 2018
Fingolimod is a daily oral medication used to treat relapsing multiple sclerosis (MS). Clinicians often adopt less frequent dosing for patients with profound drug-induced lymphopenia or other adverse events. Data on the effectiveness of alternate dose fingolimod are limited. We conducted a multicenter, retrospective, observational study at 14 sites and identified 170 patients with MS taking alternate doses of fingolimod for ≥1 month. Clinical and radiologic outcomes were collected and compared during daily and alternate fingolimod dosing. Profound lymphopenia (77%), liver function abnormalities (9%), and infections (7%) were the most common reasons for patients to switch to alternate fingolimod dosing. The median follow-up was 12 months on daily dose and 14 months on alternate dose. Most patients (64%) took fingolimod every other day during alternate dosing. Disease activity was similar on alternate dose compared to daily dose: annualized relapse rate was 0.1 on daily dose vs 0.2 on...

Both proprietary and nonproprietary medicines are expected to undergo rigorous preapproval testing and both should meet stringent health authority regulatory requirements related to quality to obtain approval. Nonproprietary (also known as copy, or generic) medicines, which base their authorization and use on the proprietary documentation and label, are often viewed as a means to help lower the cost and, thus, increase patient access. If these medicines fail to meet quality standards, such as good manufacturing practice and bioequivalence (in humans), they are then defined as substandard copies and can pose serious risks to patients in terms of safety and efficacy. Potentially noncontrolled or different manufacturing process and excipients in nonproprietary medicines may result in poor batch-to-batch reproducibility (accurate and consistent quantity of each ingredient in each capsule/tablet) and lower quality. Substandard, nonproprietary copies of medicines that are immunomodulatory or immunosuppressive are of concern to patients due to their possible untoward safety and lack of efficacy events. This article reviews the potential risks associated with nonproprietary medicines that do not meet the regulatory requirements of the United States Food and Drug Administration, the European Medicines Agency, or the World Health Organization. The clinical implications for patients are described. This article focuses on nonproprietary medicines for multiple sclerosis, particularly fingolimod, that are not identical to proprietary versions and could thus fail to meet efficacy expectations or have different impact on the safety of patients with multiple sclerosis.
Long-term safety and real-world effectiveness of fingolimod in relapsing multiple sclerosis
Patient Related Outcome Measures
With a growing number of disease-modifying therapies becoming available for relapsing multiple sclerosis, there is an important need to gather real-world evidence data regarding long-term treatment effectiveness and safety in unselected patient populations. Although not providing as high a level of evidence as randomized controlled trials, and prone to bias, realworld studies from observational studies or registries nevertheless provide crucial information on real-world outcomes of a given therapy. In addition, evaluation of treatment satisfaction and impact on quality of life are increasingly regarded as complementary outcome measures. Fingolimod was the first oral disease-modifying therapy approved for relapsing multiple sclerosis. This review aims to summarize current knowledge on the long-term effectiveness and safety outcomes of multiple sclerosis patients on fingolimod. Impact on treatment satisfaction and quality of life will be discussed according to available data.

Background: Fingolimod was the first oral therapy approved for treating relapsing-remitting multiple sclerosis (RRMS) in 2010. This open-label study evaluated the safety and efficacy of fingolideR, 0.5 mg in Iranian MS patients during one-year follow-up. Methods: A multicenter, open-label, longitudinal was designed to evaluate the safety and efficacy of fingolideR, 0.5 mg over a one-year follow-up period across 11 centers. The patients were visited by their neurologists every two months to evaluate possible adverse events and clinical disease activity considered by recording Kurtzke’s Expanded Disability Status Scale (EDSS). Results: A total of 252 patients with the mean treatment duration of 343±45.70 days were. 20 patients experienced adverse events (AEs) and serious adverse events (SAEs) such as resistant urinary tract infection (UTI), premature atrial contraction (PAC), skin allergic reaction, macular edema, chicken pox, zona, panic attacks, and exacerbations associated with ste...
Critical Appraisal of Effectiveness of Oral Fingolimod on Relapsing Multiple Sclerosis
Journal of Pharmaceutical Sciences and Community, 2017
Oral fingolimod has been recently accepted as a treatment for relapsing Multiple Sclerosis (MS) by the Indonesian Food and Drug Administration. The number of MS patients is increasing in Indonesia. There is a critical need of systematically reviewing the new medication for both efficacy and safety. This review aimed to appraise the clinical evidences of oral fingolimod for the effective treatment of relapsing MS. We searched in Pubmed database. We limited our search to only articles that were in full text, published within the last 10 years, and in English. We used the Jadad scale to measure the quality of the evidences. We only found 3 trials, all conducted with randomized and double blind design. The three trials were: the FREEDOMS I, FREEDOMS II, and TRANSFORMS studies. The FREEDOMS studies compared with placebo, and the TRANSFORMS study compared with injectable interferon. All of the studies have good quality in methodology (Jadad scale >3). The results of the three studies showed the benefit of oral fingolimod in reducing MS relapse compared with placebo with relative risk reduction range from 48% to 54%, and also in reducing new lesions in T2 brain MRI with relative risk reduction range from 35% to 74%. Our critical appraisal found that oral fingolimod improved clinical outcomes. The availability of oral fingolimod in Indonesia makes it one of the options in treatment of MS relapse in Indonesia and has been demonstrated to be effective and safe with relatively small risk.
Long-term effects of fingolimod in multiple sclerosis: The randomized FREEDOMS extension trial
Neurology, 2015
To assess long-term safety and efficacy of fingolimod in patients with relapsing-remitting multiple sclerosis (RRMS). Patients completing FTY720 Research Evaluating Effects of Daily Oral Therapy in MS (FREEDOMS) were eligible for this dose-blinded, parallel-group extension study, continuing fingolimod 0.5 mg/day or 1.25 mg/day, or switching from placebo to either dose, randomized 1:1. Efficacy variables included annualized relapse rate (ARR), brain volume loss (BVL), and confirmed disability progression (CDP). Between-group analyses were conducted in the intent-to-treat (ITT) population from FREEDOMS baseline to end of study. Within-group analyses compared years 0-2 (FREEDOMS) and years 2-4 (extension) in the extension ITT population. Of 1,272 patients (FREEDOMS ITT population), 1,033 were eligible, and 920 enrolled in the extension study (continuous-fingolimod: 0.5 mg [n = 331], 1.25 mg [n = 289]; placebo-fingolimod: 0.5 mg [n = 155], 1.25 mg [n = 145]); 916 formed the extension IT...

It is important to confirm the effectiveness and tolerability of disease-modifying treatments for relapsing–remitting multiple sclerosis (RRMS) in real-world treatment settings. This prospective observational cohort study (VIRGILE) was performed at the request of the French health authorities. The primary objective was to evaluate the effectiveness of fingolimod 0.5 mg in reducing the annualised relapse rate (ARR) in patients with RRMS. Participating neurologists enrolled all adult patients with RRMS starting fingolimod treatment between 2014 and 2016, who were followed for 3 years. Follow-up consultations took place at the investigator’s discretion. The primary outcome measure was the change in ARR at month 24 after fingolimod initiation. Relapses and adverse events were documented at each consultation; disability assessment (EDSS) and magnetic resonance imagery were performed at the investigator’s discretion. Of 1055 eligible patients, 633 patients were assessable at month 36; 405...

Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system, traditionally considered to be an autoimmune, demyelinating disease. Based on this understanding, initial therapeutic strategies were directed at immune modulation and inflammation control. At present, there are five licensed first-line disease-modifying drugs for MS in Europe, and two second-line treatments. Currently available MS therapies have shown significant efficacy throughout many trials, but they produce different side effects. Despite disease-modifying drugs being well known and safe, they require regular and frequent parenteral administration and are associated with limited long-term treatment adherence. Therefore, the development of new therapeutic strategies is warranted. Several oral compounds are in late stages of development for treating MS. fingolimod is an oral sphingosine-1-phosphate receptor modulator that has demonstrated superior efficacy compared with placebo and interfer...
