BACKGROUND AND OBJECTIVE: The dual orexin receptor antagonist daridorexant was approved in 2022 for the treatment of insomnia at doses up to 50 mg once per night. This study aimed at investigating the effect of daridorexant 50 mg at steady state on the pharmacokinetics of dabigatran, the active moiety of dabigatran etexilate, and rosuvastatin, sensitive substrates of P-glycoprotein and breast cancer resistance protein, respectively. METHODS: This single-center, open-label, fixed-sequence study enrolled 24 healthy male subjects who were dosed orally with dabigatran etexilate 75 mg on days 1 (Treatment A1) and 9 (Treatment C1) as well as rosuvastatin 10 mg on days 3 (Treatment A2) and 11 (Treatment C2). On days 7-14, daridorexant (50 mg once daily) was administered. Blood samples for the pharmacokinetics of both substrates and the pharmacodynamics of dabigatran, i.e., two coagulation tests, were collected and safety assessments performed. Noncompartmental pharmacokinetic parameters and pharmacodynamic variables were evaluated with geometric mean ratios and 90% confidence intervals of Treatment C1/C2 versus A1/A2. RESULTS: Geometric mean ratios (90% confidence interval) of dabigatran maximum plasma concentration and area under the plasma concentration-time curve were 1.3 (1.0-1.7) and 1.4 (1.1-1.9), respectively, whereas the time to maximum plasma concentration and terminal half-life were comparable between treatments. Pharmacodynamic variables showed a similar pattern as dabigatran pharmacokinetics in both treatments. Rosuvastatin pharmacokinetics were unchanged upon concomitant daridorexant administration. All treatments were well tolerated. CONCLUSIONS: A mild inhibition of P-glycoprotein was observed after administration of daridorexant (50 mg once daily) at steady state, whereas breast cancer resistance protein was not affected. CLINICAL TRIAL REGISTRATION: NCT05480475; date of registration: 29 July, 2022.

BACKGROUND: There is growing interest in the issue of disease reactivation in multiple sclerosis following fingolimod cessation. Relatively little is known about modifiers of the risk of post-cessation relapse, including the delay to commencement of new therapy and prior disease activity. OBJECTIVE: We aimed to determine the rate of relapse following cessation of fingolimod and to identify predictors of relapse following cessation. METHODS: Data were extracted from the MSBase registry in March 2019. Inclusion criteria were (a) clinically definite relapsing multiple sclerosis, (b) treatment with fingolimod for ≥ 12 months, (c) follow-up after cessation for ≥ 12 months, and (d) at least one Expanded Disability Status Scale score recorded in the 12 months before cessation. RESULTS: A total of 685 patients were identified who met criteria. The mean annualised relapse rate was 1.71 (95% CI 1.59, 1.85) in the year prior to fingolimod, 0.50 (95% CI 0.44, 0.55) on fingolimod and 0.43 (95% CI 0.38, 0.49) after fingolimod. Of these, 218 (32%) patients experienced a relapse in the first 12 months. Predictors of a higher relapse rate in the first year were: younger age at fingolimod cessation, higher relapse rate in the year prior to cessation, delaying commencement of new therapy and switching to low-efficacy therapy. CONCLUSIONS: Disease reactivation following fingolimod cessation is more common in younger patients, those with greater disease activity prior to cessation and in those who switch to a low-efficacy therapy.

BACKGROUND AND OBJECTIVE: Influenza-like illness (ILI) leads to a substantial disease burden every winter in Europe; however, oseltamivir is not frequently prescribed to ILI patients in the primary-care setting. An open-label, multi-country, multi-season, randomised controlled trial investigated the effectiveness of oseltamivir for treating ILI in 15 European countries. We aimed to evaluate whether patients presenting with ILI in primary care and being managed with the addition of oseltamivir to usual care had lower average direct and indirect costs compared to patients with usual care alone. METHODS: Resource use data were extracted from participants' daily diaries. Itemised country-specific unit costs were collected through official tariffs, pharmacies or literature. Costs were converted to 2018 values. The null hypothesis was tested based on one-sided credible intervals (CrIs) obtained by bootstrapping. Base-case analysis estimated direct cost and productivity losses using itemised costed resource use and the human capital approach. Scenario analyses with self-reported spending rather than itemised costing were also performed. RESULTS: Patients receiving oseltamivir (N = 1306) reported fewer healthcare visits, medication uses, hospital attendances and paid-work hours lost than the other patients (N = 1298). Excluding the oseltamivir cost, the average direct costs were lower in patients treated with oseltamivir from all perspectives, but these differences were not statistically significant (perspective of patient: €17 [0-95% Crl: 16-19] vs. €24 [5-100% Crl: 18-29]; healthcare provider: €37 [28-67] vs. €44 [25-55]; healthcare payers: €54 [45-85] vs. €68 [45-81]; and society: €423 [399-478] vs. €451 [390-478]). Scenario and age-group analyses confirmed these findings, but with some between-country differences. CONCLUSION: The average direct and indirect costs were consistently lower in patients treated with oseltamivir than in patients without from four perspectives (excluding the oseltamivir cost). However, these differences were not statistically significant.

BACKGROUND: The orally active dual endothelin receptor antagonist aprocitentan targets a novel pathway in the treatment of hypertension and could be a key player in the treatment of salt/volume-dependent hypertension. Its pharmacokinetic profile supports a once-daily dosing strategy. OBJECTIVE: As hypertensive patients may also experience concomitant renal disease, the objectives of this study were to evaluate the pharmacokinetics and tolerability of aprocitentan in subjects with severe renal function impairment (SRFI) and compare these with matched healthy subjects. DESIGN, SETTING, PARTICIPANTS: In this open-label, single-center, phase 1 study (NCT03165071) eight subjects with SRFI (mean estimated glomerular filtration rate [eGFR] 21.9 mL/min/1.73 m2) and eight healthy subjects (mean eGFR 94.9 mL/min/1.73 m2) received a single dose of 50 mg of aprocitentan followed by an observation period of up to 17 days. Plasma pharmacokinetic parameters of aprocitentan were derived by noncompartmental analysis of the plasma concentration-time profiles. Differences in pharmacokinetic parameters were explored using geometric means ratio (GMR) and 90% confidence intervals (CIs) with SRFI subjects as test group and healthy subjects as reference group. Safety and tolerability evaluations included adverse events (AEs), electrocardiograms, vital signs, and clinical laboratory tests. RESULTS: All 16 subjects received aprocitentan and completed the study. The pharmacokinetics of aprocitentan were similar in SRFI and healthy subjects with maximum plasma concentrations reached at 7.6 h and 5.0 h, respectively. Maximum plasma concentrations did not differ as indicated by a GMR (90% CI) of 1.04 (0.85-1.28). Due to a slightly lower observed clearance in SRFI subjects, half-life was longer (53.2 h compared to 47.4 h in healthy subjects), while exposure expressed as area under the curve was 34% higher (GMR 90% CI 1.13-1.58). There were no differences in plasma protein binding (> 99% bound). Aprocitentan was well tolerated in subjects with SRFI with no notable difference compared to healthy subjects. CONCLUSIONS: Based on these single-dose results, subjects with mild, moderate, or severe renal function can be included in clinical studies without the need for dose adjustment.

BACKGROUND AND OBJECTIVE: Vertigo derived from peripheral vestibular disorders is quite frequently encountered in daily clinical practice and can be a severely disabling symptom associated with substantial impairment of health-related quality of life for the affected patients. Betahistine, a structural analogue of histamine and presumably the most widely prescribed anti-vertigo drug worldwide, has previously been shown to be an effective and safe treatment for these patients. The objective of the present study was to evaluate whether the fixed combination of cinnarizine and dimenhydrinate (Arlevert®) is non-inferior and thus a potentially useful alternative to betahistine dihydrochloride in the treatment of patients suffering from peripheral vestibular vertigo. METHODS: In this prospective, multicenter, double-blind, randomized, non-inferiority clinical trial, outpatients from 8 ENT clinics in Austria, Bulgaria, the Czech Republic and Russia were randomly assigned to receive three times daily one tablet of either the fixed combination cinnarizine 20 mg/dimenhydrinate 40 mg or betahistine dihydrochloride 16 mg for 4 weeks. Primary endpoint was the reduction of the mean vertigo score (MVS), a validated 12-item composite score defined as the mean of 6 vertigo symptoms (dystasia and walking unsteadiness, staggering, rotary sensation, tendency to fall, lift sensation, blackout) and 6 trigger factors for vertigo (change of position, bowing, getting up, driving by car/train, head movements, eye movement), after 4 weeks of therapy, as judged by the patient on a 5-point visual analogue scale (VAS). The non-inferiority margin was set to 0.3. Secondary outcomes included the patient's and investigator's judgment of global efficacy, the patient's rating of impairment of daily activities, and safety/tolerability of the treatments. RESULTS: Three hundred and six patients (mean age 53.5 years, approximately 60% female) were enrolled and randomized to the fixed combination cinnarizine/dimenhydrinate (n = 152) or betahistine (n = 154) groups; 297 patients completed the study and 294 (146 and 148, respectively) were valid for the per-protocol analysis, which was used for the non-inferiority analysis. Treatment with cinnarizine/dimenhydrinate led to a stronger reduction of the MVS [least squares mean (LSM)] after 4-week therapy (primary endpoint) in comparison to betahistine (0.395 vs 0.488; difference: - 0.093, 95% CI - 0.180; - 0.007, p = 0.035); since the upper limit of the two-sided 95% confidence interval was not only below the non-inferiority margin of 0.3, but also entirely below 0, superiority of the fixed combination could be demonstrated. The combination preparation was also more effective after 1 week of therapy and received more favorable patient's ratings on overall efficacy and impairment of daily activities. Both treatments were very well tolerated. Only 12 patients (3.92%) reported 13 non-serious adverse events; 2 cinnarizine/dimenhydrinate-treated patients discontinued the study prematurely due to adverse events as compared to 5 betahistine-treated patients. CONCLUSION: The fixed combination of cinnarizine 20 mg and dimenhydrinate 40 mg was found to be not only non-inferior, but superior to betahistine 16 mg in the improvement of peripheral vestibular vertigo. Furthermore, taking into account a good and slightly favorable safety profile, the present study provides evidence that the fixed-combination preparation is a potent and even superior alternative to betahistine in the treatment of vertigo related to peripheral vestibular disorders.

BACKGROUND: Macitentan is a clinically approved endothelin receptor antagonist for the treatment of pulmonary arterial hypertension (PAH). Increasing use of combination drug therapy in PAH means that it is important to recognize potential drug-drug interactions (DDIs) that could affect the efficacy and safety of macitentan in patients with PAH. OBJECTIVE: Two Phase 1 studies were conducted to investigate the effect of macitentan at steady-state on the pharmacokinetics of the breast cancer resistance protein (BCRP) substrates, rosuvastatin and riociguat in healthy male subjects. Another objective was to determine the safety and tolerability of concomitant administration of rosuvastatin or riociguat with macitentan. METHODS: Healthy male subjects received a single oral dose of rosuvastatin 10 mg (n = 20) or riociguat 1 mg (n = 20) on Day 1 (reference treatment). A loading oral dose of macitentan 30 mg was administered on Day 5 followed by macitentan 10 mg once-daily from Day 6 to Day 15 (riociguat study) or Day 6 to Day 16 (rosuvastatin study). A concomitant oral dose of rosuvastatin 10 mg or riociguat 1 mg was administered on Day 10 (test treatment). Pharmacokinetics were evaluated for 96 h after treatment on Day 1 and for 144 h (riociguat study) or 168 h (rosuvastatin study) after treatment on Day 10. To compare the reference and test treatments, the geometric mean ratio was calculated for the maximum plasma concentration (Cmax), the area under the plasma concentration-time curve (AUC) from zero (pre-dose) to time of the last measured concentration above the limit of quantification (AUC0-t), the AUC from zero to infinity (AUC0-∞) and the terminal elimination half-life (t½) of rosuvastatin, riociguat and riociguat's metabolite, M1. The difference in the time to reach maximum plasma concentration (tmax) was determined by the Wilcoxon test. Trough levels of macitentan and its metabolite, ACT-132577, were measured and safety was monitored throughout. RESULTS: Ninety percent confidence intervals of the geometric mean ratios were within the bioequivalence criteria of 0.80-1.25. There was no significant difference between test and reference tmax. Rosuvastatin or riociguat did not affect the steady-state concentrations of macitentan and ACT-132577. The adverse event profile was consistent with the known safety profiles of the drugs. CONCLUSIONS: Macitentan 10 mg did not affect the pharmacokinetics of BCRP substrates, rosuvastatin or riociguat in healthy male subjects. EudraCT numbers: 2017-003095-31 and 2017-003502-41.

BACKGROUND AND OBJECTIVE: Non-persistence with secondary preventive measures, including medications such as statins, adversely affects the prospects of successful outcomes. This study was aimed at evaluating non-persistence with statin therapy in cohorts of young and elderly patients after a transient ischaemic attack (TIA) and identifying patient-associated characteristics that influence the risk for non-persistence. METHODS: The study cohorts included 797 adult patients who were initiated on statin therapy following a TIA diagnosis between 1 January 2010 and 31 December 2010. Patients were followed up for 3 years and those with a treatment gap of at least a 6-month period were considered 'non-persistent'. In order to identify any age-related differences, all analyses were conducted in the entire study cohort (n = 797) as well as separately in the 'younger' (aged <65 years, n = 267) and the 'older' (aged ≥65 years, n = 530) patients. RESULTS: Non-persistence was significantly more common in younger patients compared to older patients (67.8% vs. 49.1%; p < 0.001). Factors that decreased the probability of non-persistence in younger and older patients included diabetes mellitus (hazard ratio [HR] = 0.72 and HR = 0.64, respectively) and hypercholesterolaemia (HR = 0.43 and HR = 0.62, respectively). Female gender (HR = 1.42) was associated with a higher and increasing number of medications taken (HR = 0.93), with lower probability for non-persistence in younger patients but not in the older patients. CONCLUSIONS: Our results indicate that certain patients with TIA require special counselling to improve persistence with statin therapy. These include younger patients, especially females and those not on polypharmacy, and both younger and older patients without diabetes mellitus or hypercholesterolaemia.

BACKGROUND AND OBJECTIVE: Once-daily oral fingolimod is approved in the EU as escalation treatment for adult patients with highly active relapsing multiple sclerosis (MS). The efficacy and safety profiles of fingolimod have been well established in a large clinical development programme and several papers reflecting the experience with fingolimod in real-world settings have been published to date. The GOLEMS study was designed to evaluate the efficacy, safety and tolerability of fingolimod and the impact of fingolimod treatment on disability progression and work capability in patients with MS in routine clinical practice in the Czech Republic. METHODS: GOLEMS was a national, multicentre, non-interventional, single-arm study conducted to analyse the outcomes of a minimum of 12 months of fingolimod therapy on primary and secondary endpoints. The primary endpoint was to assess the proportion of relapse-free patients and severity of MS relapses in patients treated with fingolimod for 12 months. Secondary endpoints included assessment of changes in disability progression evaluated by the Expanded Disability Status Scale (EDSS) score and work capability assessment measured through voluntary completion of the WPAI-GH questionnaire. The predictive factors for relapse-free status during fingolimod treatment were also analysed. RESULTS: Of the 240 enrolled patients, 219 completed the 12-month treatment period at the time of final analysis. In the efficacy set (N = 237), the proportion of relapse-free patients increased from 47 patients (19.6 %; 95 % confidence interval [CI] 14.8-25.2) in the year before fingolimod initiation to 152 patients (64.1 %; 95 % CI 58.0-70.2) after 1 year of fingolimod treatment. Of the 85 patients who experienced at least one relapse after 1 year of fingolimod treatment, 53 (62.4 %; 95 % CI 51.7-71.9) reported only one relapse, while 25 (29.4 %; 95 % CI 20.8-39.8) and seven (8.2 %; 95 % CI 4.0-16.0) patients had ≥2 relapses, respectively. No significant changes were observed in EDSS scores over the 12-month treatment period compared with baseline. The absolute number of relapses during 2 years before initiation of fingolimod treatment and baseline EDSS scores were identified as significant independent predictors for 'being relapse-free' during the 12-month fingolimod treatment period. No trend was established in work capability or number of missed days at work due to the large proportion of missing data. Of 240 enrolled patients, 27 (11.3 %) patients discontinued the study at or before the 12-month visit, 16 (6.7 %) discontinued because of adverse events related to study drug. Only six (2.5 %) patients reported serious adverse events related to the study drug. CONCLUSION: The results confirm the favourable safety and efficacy profile of fingolimod under real-world conditions, consistent with phase III trials.

BACKGROUND AND OBJECTIVE: Vertigo may arise from dysfunction in the peripheral and/or the central vestibular system. Simultaneous activity of a medication at both sites will serve to improve the efficacy of antivertigo treatment. The aim of this study was to compare the efficacy and tolerability of a fixed combination of the peripherally acting cinnarizine (20 mg) plus the centrally acting dimenhydrinate (40 mg) with those of equally dosed monotherapies in the treatment of vertigo of various origins. METHODS: This prospective, randomized, double-blind, active-controlled, multicentre study included patients who assessed at least one vertigo symptom as being of at least medium intensity (≥2) on a 5-point visual analogue scale (VAS; ranging from 0 = not present to 4 = very strong) and who had pathological vestibulospinal movement patterns and/or nystagmus reactions. Patients were randomly assigned to receive either cinnarizine 20 mg/dimenhydrinate 40 mg as a fixed combination, cinnarizine 20 mg as monotherapy or dimenhydrinate 40 mg as monotherapy, each three times daily for 4 weeks. Patients were examined at baseline (t(0)), and after 1 week (t(1w)) and 4 weeks (t(4w)) of treatment. The primary efficacy endpoint was the decrease in mean vertigo score (MVS) at t(4w), which was calculated by averaging the total score for 12 individual vertigo symptoms, each assessed using the 5-point VAS. RESULTS: The study included 182 patients, of whom 177 were evaluable for efficacy. The mean ± SD reduction in MVS after 4 weeks of treatment with the fixed combination (-1.44 ± 0.56) was significantly greater than the reductions with each of the active treatments alone (cinnarizine -1.04 ± 0.53; dimenhydrinate -1.06 ± 0.56; p = 0.0001, both comparisons). Cinnarizine 20 mg/dimenhydrinate 40 mg as a fixed combination was associated with a significantly higher responder rate (78% of patients with MVS ≤0.5 at t(4w)) than the monotherapies. The odds ratios for MVS ≤0.5 at t(4w) in the cinnarizine or dimenhydrinate groups versus the fixed combination group were 0.345 and 0.214, respectively. The fixed combination reduced concomitant vegetative symptoms significantly more effectively than cinnarizine at both t(1w) (p < 0.05) and t(4w) (p < 0.01). Nine patients reported 15 adverse events (AEs) [three AEs for the fixed combination, six AEs each for cinnarizine and dimenhydrinate]. At t(4w) the tolerability of the treatments was rated as very good or good by almost all patients in all groups (fixed combination and dimenhydrinate 96.6% each; cinnarizine 98.3%). CONCLUSION: The fixed combination of cinnarizine 20 mg/dimenhydrinate 40 mg was an effective and well tolerated treatment for patients with vestibular vertigo of central and/or peripheral origin. The efficacy of the fixed combination exceeded that of each of the equally dosed active substances given as monotherapy, leading to higher responder rates, and showed a very good and comparable tolerability with a similar or even smaller rate of adverse events than the active substances given alone.

BACKGROUND AND OBJECTIVE: Vestibular dysfunction commonly leads to - often severe - vertigo symptoms. The objective of this study was to compare the antivertiginous efficacy and tolerability of a fixed combination of cinnarizine/dimenhydrinate with those of betahistine in patients with acute vertigo due to vestibular disorders. METHODS: Sixty-six patients experiencing acute vertigo attacks participated in this prospective, double-blind, three-centre, comparative study. Patients who assessed at least one vertigo symptom as being of medium intensity (> or =2) on a 5-point visual analogue scale (VAS; from 0 = no symptoms to 4 = very severe symptoms) were randomly allocated to treatment with the fixed combination of cinnarizine 20 mg and dimenhydrinate 40 mg three times daily or betahistine 12 mg three times daily for 4 weeks. The primary efficacy endpoint was change in mean vertigo score, as determined by patients' assessments of 12 individual vertigo symptoms on the 5-point VAS after 4 weeks of treatment. RESULTS: Treatment with the fixed combination led to significantly greater improvements in mean vertigo scores than the reference therapy betahistine after 4 weeks of therapy (p = 0.013). The differences were clinically relevant, based on the Mann-Whitney estimator. Furthermore, the incidence of vertigo-associated vegetative symptoms was significantly reduced after 1 (p = 0.004) and 4 weeks (p = 0.023) in the fixed-combination group relative to the betahistine group. Three patients, all of them in the betahistine group, reported adverse events, none of which was considered serious. Almost all patients (n = 62) rated the tolerabilities of both medications as very good or good. CONCLUSION: The fixed combination of cinnarizine/dimenhydrinate was shown to be an effective and very well tolerated treatment option for patients with acute vertigo due to vestibular disorders. The combination proved to be significantly more efficient in reducing vertigo and associated vegetative symptoms than betahistine in such patients.
