The efficacy and safety of fingolimod in patients with relapsing multiple sclerosis: A meta-analysis.

ABSTRACT:

Aims

The aim of the present meta-analysis was to evaluate the efficacy and safety of fingolimod in patients with relapsing multiple sclerosis (RMS).

Methods

PubMed, Embase, the Cochrane Library and ClinicalTrials.gov were searched for relevant studies. Two authors independently selected the studies, assessed the risk of bias, and extracted the data. The meta-analysis was performed in RevMan 5.3 provided by the Cochrane Collaboration.

Results

Ten studies met the inclusion criteria. In patients with RMS, fingolimod demonstrated a significantly lower annualized relapse rate (0.5 mg/d: mean difference [95% confidence interval] = -0.22 [-0.29 to -0.14]; 1.25 mg/d: -0.26 [-0.36 to -0.16]; 5 mg/d: -0.41 [-0.72 to -0.10]) than placebo. Fingolimod also exhibited a favorable performance on other magnetic resonance imaging outcomes and improved the quality of life in patients. No significant difference was noted in the prevalence of adverse events between the fingolimod treatment group and the placebo/disease-modifying therapy groups.

Conclusions

Fingolimod may offer benefits for RMS patients and presents an acceptable safety profile.

Project description:Fingolimod approval was based mainly on two clinical trials, FREEDOMS and TRANSFORMS, which demonstrated the efficacy and safety of fingolimod in patients with multiple sclerosis (MS). We present an observational study that validates these trials findings in a real-world setting, whereby the effectiveness and safety of fingolimod was assessed in Seville's' (Spain) clinical practice. This retrospective study in MS patients assessed effectiveness (relapses, EDSS, gadolinium-enhancing T1 and new/enlarged T2-weighted lesions): total cohort (n = 249) and stratified according to prior treatment (glatiramer acetate/interferon beta-1 [immunomodulator], natalizumab, naïve), gender, basal EDSS score, basal Gd+ lesions, ARR prior to treatment, age at treatment initiation and number of prior treatments. A multivariante model was used to assess the ARR with baseline characteristics. The safety profile (adverse events [AEs]) was also described. Fingolimod reduced the annualized relapse rate (ARR) by 75%, 67% and 85% in the total cohort, patients previously treated with immunomodulatory and naïve patients (p<0.0001 all cases). However, patients previously treated with natalizumab kept a constant ARR. The ARR results and the consequent increase in the proportion of relapse-free patients were independent of the age at treatment initiation, number of prior treatments, gender and basal Gd+ lesions. Although fingolimod was effective regardless the basal EDSS score and ARR prior to fingolimod treatment, better outcomes were observed in patients with basal EDSS score <3 (0.2 vs. 0.4; p = 0.0244) and ARR ? 2 prior to fingolimod treatment (p = 0.0338). Only the basal EDSS score was association with ARR in the first 24 months of fingolimod treatment in the multivariante model (p = 0.0439). The cumulative probability of disability progression was 20% (month-24) in the total cohort, and was independent from prior treatment, age at treatment initiation, number of prior treatments, gender, basal EDSS score, basal Gd+ lesions and ARR prior to treatment. The real-world fingolimod benefits observed in this study seem to be similar than those observed in previous clinical trials.

Project description:BackgroundThe low level of disease activity and manageable safety profile seen with fingolimod versus placebo in a 6-month, phase 2, randomized controlled trial in Japanese patients with relapsing multiple sclerosis (MS; ClinicalTrials.gov Identifier NCT00537082) were maintained in the initial 6-month observational study extension. Here, we report long-term safety and efficacy results of the 3-year follow-up to the phase 2 study extension.MethodsThe 6-month core study was completed by 147 patients, of whom 143 entered the extension and took at least one dose of fingolimod. Those originally randomized to placebo were re-randomized to fingolimod 1.25 mg (n = 23) or 0.5 mg (n = 27). During the extension, the patients taking fingolimod 1.25 mg (n = 46) were switched to open-label fingolimod 0.5 mg, and those originally randomized to fingolimod 0.5 mg (n = 47) continued with open-label fingolimod 0.5 mg.ResultsContinuous fingolimod treatment was associated with a sustained low level of MRI and relapse activity for the duration of the extension phase; 75-100% (range across all assessment time points up to end of study) of patients remained free of Gd-enhanced T1 lesions, 88-100% remained free of new/newly enlarged T2 lesions, and 45-62% remained relapse-free. In patients who switched to the active treatment, a 79.5% decrease in annualized relapse rate (ARR; from 1.131 before switch to 0.232 6-months after switch) was observed in the first 6 months of the extension phase and thereafter remained low until the end of study (0.16-0.31 across all assessment time points after switch up to end of study). The mean number of Gd-enhanced T1 and new/newly enlarged T2 lesions decreased up to month 9 and thereafter remained low until the end of study (0.0-0.1 and 0.0-0.3, respectively, across all assessment time points after switch up to end of study). Fingolimod was generally well-tolerated and the safety profile was consistent with the core and 6-month extension. Serious adverse events were reported in 13.3% of patients during the extension study, with the range in the continuous fingolimod and placebo-fingolimod switch groups (3.7-21.7%) being similar to that reported in the core study for the placebo and fingolimod groups (5.3-20.4%).ConclusionContinuous fingolimod treatment over 36 months was associated with maintained efficacy and a manageable safety profile with no new safety signals. These results indicate that fingolimod provides long-term treatment benefit for Japanese patients with relapsing MS.Trial registrationClinicalTrials.gov NCT00670449 (April 28, 2008).

Project description:ImportanceDoses of fingolimod lower than 0.5 mg per day were not investigated during the fingolimod clinical development program. Whether lower doses of fingolimod might retain efficacy with fewer safety risks remains unknown.ObjectiveTo evaluate the efficacy and safety of fingolimod, 0.5 mg, and fingolimod, 0.25 mg, compared with glatiramer acetate and to assess whether these doses of fingolimod show superior efficacy to glatiramer acetate in adult patients with relapsing-remitting multiple sclerosis.InterventionsFingolimod, 0.5 mg, or fingolimod, 0.25 mg, orally once per day or glatiramer acetate, 20 mg, subcutaneously once per day.Design, setting, and participantsThe Multiple Sclerosis Study Evaluating Safety and Efficacy of Two Doses of Fingolimod Versus Copaxone (ASSESS) was a phase 3b multicenter randomized rater-blinded and dose-blinded 12-month clinical trial conducted between August 9, 2012, and April 30, 2018 (including the time required to recruit participants). A total of 1461 patients aged 18 to 65 years with relapsing-remitting multiple sclerosis were screened, and 1064 participants were randomized. These participants had at least 1 documented relapse during the previous year or 2 documented relapses during the previous 2 years and an Expanded Disability Status Scale score of 0 to 6 at screening. Data were analyzed between September and November 2018.Main outcomes and measuresThe superiority of the fingolimod doses was tested hierarchically, with fingolimod, 0.5 mg, vs glatiramer acetate, 20 mg, tested first, followed by fingolimod, 0.25 mg, vs glatiramer acetate, 20 mg. The primary end point was the reduction in annualized relapse rate (ARR). Magnetic resonance imaging parameters, safety, and tolerability were also assessed.ResultsOf 1461 adult patients screened, 1064 participants (72.8%) were randomized (mean [SD] age, 39.6 [11.0] years; 792 women [74.4%]) to 3 treatment groups: 352 participants received fingolimod, 0.5 mg, 370 participants received fingolimod, 0.25 mg, and 342 participants received glatiramer acetate, 20 mg. In total, 859 participants (80.7%) completed the study. Treatment with fingolimod, 0.5 mg, was superior to treatment with glatiramer acetate, 20 mg, in reducing ARR (40.7% relative reduction); the relative reduction with fingolimod, 0.25 mg, was 14.6%, which was not statistically significant (for fingolimod, 0.5 mg, ARR, 0.15; 95% CI, 0.11-0.21; for fingolimod, 0.25 mg, ARR, 0.22; 95% CI, 0.17-0.29; for glatiramer acetate, 20 mg, ARR, 0.26; 95% CI, 0.20-0.34). Treatment with both fingolimod doses (0.5 mg and 0.25 mg) significantly reduced new or newly enlarging T2 and gadolinium-enhancing T1 lesions compared with treatment with glatiramer acetate. Adverse events were reported in similar proportions across treatment groups (312 participants [90.4%] in the fingolimod, 0.5 mg, group, 323 participants [88.3%] in the fingolimod, 0.25 mg, group, and 283 participants [87.3%] in the glatiramer acetate group).Conclusions and relevanceFingolimod, 0.5 mg, demonstrated superior clinical efficacy compared with glatiramer acetate, 20 mg, and had a superior benefit-risk profile compared with fingolimod, 0.25 mg, in adult participants with relapsing-remitting multiple sclerosis.Trial registrationClinicalTrials.gov Identifier: NCT01633112.

Project description:IntroductionFingolimod 0.5 mg is an orally active sphingosine 1-phosphate receptor modulator approved for use in adults with relapsing multiple sclerosis (MS). The efficacy and safety profile of fingolimod has been well characterized in a large clinical development program. Here, we report the safety and tolerability of fingolimod in relapsing-remitting MS (RRMS) patients from Latin America.MethodsA total of 162 patients with RRMS, predominantly from Latin American countries (138/162), were enrolled in this 16-week, single treatment arm, open-label, multi-center study. Unlike the phase III pivotal studies, this study permitted enrollment of patients with controlled diabetes, certain cardiac and pulmonary conditions, older age, and higher baseline Expanded Disability Status Scale. All patients were monitored clinically for a minimum of 6 hours after the first dose. Safety and tolerability assessments were based on adverse events, clinically notable laboratory abnormalities, vital signs, ophthalmic examinations, and electrocardiograms.ResultsOverall, the safety and tolerability profile was consistent with that reported previously in phase 3 studies and the FIRST study. Adverse events (AEs) were predominantly mild (n = 49, 35.5%) or moderate (n = 27, 19.6%). Three patients (2.2%) discontinued fingolimod due to AEs. Infections were reported in 33 patients (23.9%) and were predominantly mild in nature (n = 28, 20.3%). Increases in alanine aminotransferase enzymes of ≥3, ≥5 and ≥10 upper limit of normal were reported in five (3.7%), three (2.2%) and one (0.7%) patients, respectively. Hypertension cases (n = 3; 2.2%) did not result in treatment discontinuation and were controlled with antihypertensive therapy. Following first-dose administration, the majority of patients (90.6%) were discharged at 6 h. During the first-dose monitoring, 5 cases of bradycardia were reported; none required extended monitoring or treatment for symptomatic bradycardia.ConclusionThe first dose of fingolimod 0.5 mg was well tolerated in RRMS patients from Latin America. The overall safety profile was clinically manageable and consistent with previous fingolimod studies.FundingNovartis.Trial registrationClinicalTrials.gov #NCT01497262.
