Large scale application of the Finnish diabetes risk score in Latin American and Caribbean populations: a descriptive study.

Background: The prevalence of type 2 diabetes (T2D) continues to increase in the Americas. Identifying people at risk for T2D is critical to the prevention of T2D complications, especially cardiovascular disease. This study gauges the ability to implement large population-based organized screening campaigns in 19 Latin American and Caribbean countries to detect people at risk for T2D using the Finnish Diabetes Risk Score (FINDRISC). Methods: This cross-sectional descriptive analysis uses data collected in a sample of men and women 18 years of age or older who completed FINDRISC via eHealth during a Guinness World Record attempt campaign between October 25 and November 1, 2021. FINDRISC is a non-invasive screening tool based on age, body mass index, waist circumference, physical activity, daily intake of fruits and vegetables, history of hyperglycemia, history of antihypertensive drug treatment, and family history of T2D, assigning a score ranging from 0 to 26 points. A cut-off point of ≥ 12 points was considered as high risk for T2D. Results: The final sample size consisted of 29,662 women (63%) and 17,605 men (27%). In total, 35% of subjects were at risk of T2D. The highest frequency rates (FINDRISC ≥ 12) were observed in Chile (39%), Central America (36.4%), and Peru (36.1%). Chile also had the highest proportion of people having a FINDRISC ≥15 points (25%), whereas the lowest was observed in Colombia (11.3%). Conclusions: FINDRISC can be easily implemented via eHealth technology over social networks in Latin American and Caribbean populations to detect people with high risk for T2D. Primary healthcare strategies are needed to perform T2D organized screening to deliver early, accessible, culturally sensitive, and sustainable interventions to prevent sequelae of T2D, and reduce the clinical and economic burden of cardiometabolic-based chronic disease.

Satisfaction and adherence with glatiramer acetate 40mg/mL TIW in RRMS after 12 months, and the effect of switching from 20mg/mL QD.

BACKGROUND: Patient satisfaction with treatment in relapsing-remitting multiple sclerosis (RRMS) has a direct impact on adherence to treatment and, consequently, upon treatment outcomes and costs. Patient-reported outcomes (PROs) are a common method for determining patient satisfaction in MS and other diseases. METHODS: The 12-month, open-label, Phase IV CONFIDENCE study assessed patient satisfaction and treatment adherence, using PROs, as well as safety outcomes in patients with RRMS treated with glatiramer acetate (GA). In the previously reported (Cutter et al., 2019) initial 6-month core phase of the study, patients were randomized to receive three-times-weekly (TIW) GA 40 mg/mL (GA40; n = 431) or once-daily GA 20 mg/mL (GA20; n = 430). In the 6-month, single-arm extension phase, 789 patients completing the core phase were treated with GA40 to determine whether benefits observed in the core phase were sustained during the extension phase, to ascertain if switching from GA20 to GA40 resulted in PRO changes, and to assess safety outcomes. RESULTS: Superior PRO scores for patient satisfaction with treatment, patient perception of treatment convenience, and symptomatic changes (fatigue impact and mental health) observed in the GA40 group versus the GA20 group in the core phase were all maintained in the extension phase. Treatment adherence, significantly greater in the GA40 versus the GA20 group in the core phase, was sustained in patients continuing to receive GA40 in the extension phase, while those who switched from GA20 to GA40 increased their adherence during the extension phase. Safety variables remained consistent throughout the study, with no notable changes observed in patients switching from GA20 to GA40. CONCLUSIONS: Data from the extension phase of the CONFIDENCE study show that the benefits associated with GA40 treatment in terms of medication satisfaction, treatment convenience perception, symptomatic changes in fatigue impact and mental health status, and treatment adherence were maintained over a 12-month observation period. These results confirm the preferential utility of GA40 versus GA20 in clinical practice, with no additional safety concerns associated with switching from GA20 to GA40.

Higher satisfaction and adherence with glatiramer acetate 40 mg/mL TIW vs 20 mg/mL QD in RRMS.

BACKGROUND: Patients who perceive their medication to be ineffective or inconvenient are less likely to be adherent to treatment, with potentially significant consequences on long-term clinical outcomes. Many patients with multiple sclerosis (MS) are nonadherent to treatment despite demonstrated efficacy of disease-modifying therapies (DMTs). While glatiramer acetate (GA; Copaxone®, Teva Pharmaceuticals) both 20 mg/mL once daily (GA20) and 40 mg/mL three times weekly (GA40) have demonstrated efficacy in relapsing-remitting MS (RRMS), GA40 has a superior tolerability profile in addition to a more convenient dosing schedule. These characteristics may give rise to greater treatment satisfaction and higher rates of adherence with potentially beneficial effects on clinical outcomes and health-related costs. METHODS: CONFIDENCE was a Phase 4, interventional, open-label, randomized, 2-arm, parallel-group, global study with a duration of 6 months. Patients (N = 861) were randomly assigned 1:1 to receive GA20 (n = 430) or GA40 (n = 431) during the core phase. The primary endpoint was patient-reported medication satisfaction using the Medication Satisfaction Questionnaire (MSQ). Secondary endpoints included self-reported convenience perception using the Treatment Satisfaction Questionnaire for Medication-9 convenience component, symptomatic changes (Modified Fatigue Impact Scale, MFIS), and Mental Health Inventory (MHI). Treatment adherence was measured by Multiple Sclerosis Treatment Adherence Questionnaire. Results from the core phase were included. RESULTS: During the core phase, 857 patients received treatments. Patients on GA40 were statistically significantly more satisfied with their medication than those on GA20 (LSM difference in MSQ, 0.3; 95% CI, 0.2, 0.5; p<0.001). Additionally, patients on GA40 found the treatment more convenient (p<0.001), were more adherent (p = 0.002), and reported statistically significant greater improvements in the MFIS Cognitive (p = 0.043) and the MHI Behavior Control (p = 0.014) subscales versus those on GA20. There were no new safety findings. CONCLUSIONS: Higher levels of satisfaction, perception of convenience, and adherence were reported by patients on GA40 than those on GA20. CLINICAL TRIAL REGISTRATION NUMBER: This trial was registered with ClinicalTrials.gov (NCT02499900).

Pregnancy Outcomes from the Branded Glatiramer Acetate Pregnancy Database.

BACKGROUND: Appropriate counseling and treatment for women with multiple sclerosis (MS) who may become pregnant requires an understanding of the effects of exposure to disease-modifying therapies (DMTs) during pregnancy. Current reports and studies are limited in their usefulness, mostly by small sample size. Branded glatiramer acetate (GA) is a DMT approved for the treatment of relapsing forms of MS. For more than 2 decades, it has been shown to be efficacious and to have a favorable safety profile. The Teva Pharmaceutical Industries Ltd global pharmacovigilance database comprises data from more than 7000 pregnancies, during which women with MS were exposed to treatment with branded GA. METHODS: We analyzed data from Teva's global pharmacovigilance database. Pregnancy outcomes for patients treated with branded GA were compared with reference rates of abnormal pregnancy outcomes reported in two large registries representing the general population. RESULTS: Pregnancies exposed to branded GA were not at higher risk for congenital anomalies than what is expected in the general population. CONCLUSIONS: These data provide evidence that branded GA exposure during pregnancy seems safe, without teratogenic effect.

Gene expression studies of a human monocyte cell line identify dissimilarities between differently manufactured glatiramoids.

Glatiramer Acetate (GA) has provided safe and effective treatment for multiple sclerosis (MS) patients for two decades. It acts as an antigen, yet the precise mechanism of action remains to be fully elucidated, and no validated pharmacokinetic or pharmacodynamic biomarkers exist. In order to better characterize GA's biological impact, genome-wide expression studies were conducted with a human monocyte (THP-1) cell line. Consistent with previous literature, branded GA upregulated anti-inflammatory markers (e.g. IL10), and modulated multiple immune-related pathways. Despite some similarities, significant differences were observed between expression profiles induced by branded GA and Probioglat, a differently-manufactured glatiramoid purported to be a generic GA. Key results were verified using qRT-PCR. Genes (e.g. CCL5, adj. p < 4.1 × 10(-5)) critically involved in pro-inflammatory pathways (e.g. response to lipopolysaccharide, adj. p = 8.7 × 10(-4)) were significantly induced by Probioglat compared with branded GA. Key genes were also tested and confirmed at the protein level, and in primary human monocytes. These observations suggest differential biological impact by the two glatiramoids and warrant further investigation.

Fingolimod therapy in early multiple sclerosis: an efficacy analysis of the TRANSFORMS and FREEDOMS studies by time since first symptom.

AIMS: The phase 3 TRANSFORMS and FREEDOMS studies established the efficacy of fingolimod in reducing multiple sclerosis (MS) relapses and magnetic resonance imaging lesions compared with intramuscular (IM) interferon (IFN) ß-1a and placebo over 12 and 24 months, respectively. METHODS: To investigate the efficacy of fingolimod at the approved 0.5 mg dose in patients early in the MS disease course, post hoc subgroup analyses of TRANSFORMS (n = 272) and FREEDOMS (n = 217) data were conducted in patients who experienced their first MS symptom <3 years before randomization. RESULTS: Fingolimod 0.5 mg reduced annualized relapse rate by 73.4% (P = 0.0002) versus IFNß-1a IM and by 67.4% (P < 0.0001) versus placebo in patients with <3 years since first symptom; respective reductions were 45.4% and 51.4% in subgroups of patients with ≥3 years since first symptom. For patients with <3 years since their first symptom, significantly fewer new/newly enlarged T2 lesions were observed with fingolimod versus IFNß-1a IM (mean number, 1.94 vs. 2.95; P = 0.036) or placebo (4.1 vs. 10.7; P < 0.001); the mean number of gadolinium-enhancing T1 lesions was significantly reduced versus placebo (0.3 vs. 1.1; P < 0.001). CONCLUSION: Fingolimod 0.5 mg is highly effective in reducing relapses and MRI activity in patients early in the MS disease course.

Impact of prior treatment status and reasons for discontinuation on the efficacy and safety of fingolimod: Subgroup analyses of the Fingolimod Research Evaluating Effects of Daily Oral Therapy in Multiple Sclerosis (FREEDOMS) study.

BACKGROUND: Fingolimod is a once-daily, oral sphingosine 1-phosphate receptor modulator approved for the treatment of relapsing multiple sclerosis. OBJECTIVE: This post-hoc analysis of phase 3 FREEDOMS data assessed whether the effects of fingolimod are consistent among subgroups of patients defined by prior treatment history. METHODS: Annualized relapse rate and safety profile of treatment with fingolimod 0.5mg, 1.25mg, or placebo once-daily for 24 months were analyzed in 1272 relapsing multiple sclerosis patients, by subgroups based on disease-modifying therapy history (treatment-naive; prior interferon-ß or glatiramer acetate), reason for discontinuation of prior disease-modifying therapy (unsatisfactory therapeutic response or adverse events), and prior disease-modifying therapy duration. RESULTS: Both fingolimod doses significantly reduced annualized relapse rate in patients that received prior interferon-ß or glatiramer acetate, discontinued prior disease-modifying therapy owing to unsatisfactory therapeutic effect, were treatment-naive, or had prior disease-modifying therapy duration of >1-3 years (P≤0.0301 for all comparisons vs placebo). Fingolimod 1.25mg resulted in greater reductions in annualized relapse rate in patients that discontinued prior disease-modifying therapy for adverse events or had prior disease-modifying therapy duration of ≤1 year or >3 years (P≤0.0194 vs placebo). CONCLUSIONS: Fingolimod demonstrated similar efficacy in relapsing multiple sclerosis patients regardless of prior treatment history. Clinicaltrials.gov identifier: NCT00289978.

Medication satisfaction in schizophrenia: a blinded-initiation study of paliperidone extended release in patients suboptimally responsive to risperidone.

Patient-reported outcomes, including treatment satisfaction, are now recognized as important and valid measures in assessment of therapeutic interventions. This randomized, 6-week, prospective, blinded-initiation study evaluated medication satisfaction as a primary outcome measure in a schizophrenia trial. Participants with suboptimal response to oral risperidone were randomized to paliperidone extended release (ER) immediate or delayed (week 2) initiation. Primary endpoint was change in Medication Satisfaction Questionnaire (MSQ; ratings from 1=extremely dissatisfied to 7=extremely satisfied) score at endpoint (last observation carried forward) for the overall population (all randomized participants). In total, 201 participants were randomized to immediate (n=100) or delayed (n=101) initiation of paliperidone ER. In the overall population, the mean + or - standard deviation MSQ score improved from 2.7 + or - 0.8 (very to somewhat dissatisfied) at baseline to 5.1 + or - 1.2 (somewhat satisfied) at endpoint (P<0.001). On the basis of dichotomized analysis of the MSQ scale (score 1-4=dissatisfied, 5-7=satisfied), 82.7% of participants were satisfied with their medication at endpoint. At the 2-week time point, significantly more participants in the immediate initiation group reported satisfaction (67.7%) compared with those in the delayed initiation group (45.3%) (P=0.002), who were still receiving risperidone at this time. Positive And Negative Syndrome Scale total scores also improved from baseline to endpoint (-12.9 + or - 13.1; P<0.001). Most common adverse events were insomnia (9.1%), constipation (7.6%), headache (7.6%) and somnolence (6.6%). Participants with schizophrenia who were suboptimally responsive to risperidone reported improved medication satisfaction after initiation of paliperidone ER.

Psychometric evaluation of the Medication Satisfaction Questionnaire (MSQ) to assess satisfaction with antipsychotic medication among schizophrenia patients.

The Medication Satisfaction Questionnaire (MSQ) is a single-item questionnaire which evaluates satisfaction with antipsychotic medication in schizophrenia patients. This study evaluated the reliability and validity for its use in research and clinical settings. Data pooled across treatment groups (control vs. Paliperidone ER) from a randomized 6-week study were used to conduct four psychometric assessments of the MSQ: (1) test-retest reliability, (2) convergent validity, (3) known-groups validity, and (4) minimally important difference (MID). This analysis included 191 randomized subjects. Test-retest reliability was evaluated for patients with no change in satisfaction from weeks 2 to 4 and weeks 4 to 6 (ICC=0.80; 0.83, respectively). Convergent validity was demonstrated through large correlations with Treatment Satisfaction Questionnaire for Medication (TSQM) global score (r=0.72-0.77), and through small correlations with variables measuring clinical symptoms and functioning (e.g., Positive and Negative Syndrome Scale (PANSS) total score [r=-0.30 to -0.17], CGI-S [r=-0.35 to -0.27], SF-36 Physical Functioning Score [r=0.18] and side effects and extrapiramidal measures (including UKU, ESRS-A, SAS). Mean MSQ scores were significantly different between those who completed and discontinued the study, and between different satisfaction groups based on TSQM, demonstrating good known-groups validity. MID estimates for the MSQ ranged from 0.47 (standard error of measurement) to 0.58 (anchor-based method). Results suggest that the MSQ has acceptable reliability and validity, making this single-item questionnaire appropriate and easy to use in clinical research and potentially in clinical practice. A 1-point change on the MSQ may be considered clinically meaningful.

Topiramate monotherapy in newly diagnosed epilepsy in children and adolescents.

A double-blind, dose-controlled study evaluated topiramate as monotherapy in 470 patients with newly diagnosed (< or = 3 months) epilepsy or epilepsy relapse in the absence of therapy. In addition to having at least 2 lifetime-unprovoked seizures, patients had 1 or 2 partial-onset seizures or generalized-onset tonic-clonic seizures during a 3-month retrospective baseline. The trial included a large cohort (N = 151, 32%) of children and adolescents 6 to 15 years of age. Eligible patients were randomized to treatment groups in which topiramate was titrated to target maintenance dosages of either 400 mg/day (n = 77) or 50 mg/day (n = 74). Patients were followed for at least 6 months. Based on Kaplan-Meier analyses, the primary efficacy endpoint of time to first seizure favored the higher topiramate dose in both the overall population and the cohort of children/adolescents. The probability that children/adolescents remaining in the study were seizure free at 6 months was 78% in the 50-mg target dose group and 90% with the higher dose. At 12 months, the probability of being seizure free was 62% and 85%, respectively. The incidence of treatment-limiting adverse events was 4% in the 50-mg target dose group and 14% in the group assigned to 400 mg as a target dose. The most common adverse events, excluding typical childhood illnesses, were headache, appetite decrease, weight loss, somnolence, dizziness, concentration/attention difficulty, and paresthesia. As shown in this subset analysis, topiramate is effective and well tolerated as monotherapy in children and adolescents.

Topiramate pharmacokinetics in children with epilepsy aged from 6 months to 4 years.

PURPOSE: To study the pharmacokinetics of topiramate (TPM) at steady state in children younger than 4 years comedicated with other antiepileptic drugs (AEDs). METHODS: Twenty-two children aged 6 months to 4 years with pharmacoresistant partial or generalized epilepsy were enrolled in an open-label prospective study. Children were assigned to different groups according to comedication with enzyme-inducing AEDs (n = 8), valproic acid (VPA) (n = 6), or other AEDs not known to affect drug metabolism (neutral AEDs, n = 7). One child was receiving treatment with both enzyme-inducing AEDs and VPA. After dose titration, blood samples were collected at steady state just before and 0.5, 1, 1.5, 2, 4, 6, 8, and 12 h after the morning dose of TPM. Pharmacokinetic parameters were determined by a noncompartmental method. RESULTS: TPM apparent oral clearance (CL/F) was significantly higher in children taking enzyme-inducing AEDs (85.4 +/- 34.0 ml/h/kg) than in those receiving VPA (49.6 +/- 13.6 ml/h/kg) or neutral AEDs (46.5 +/- 12.8 ml/h/kg). Conversely, dose-normalized areas under the plasma TPM concentration curves (0-12 h) were significantly lower in enzyme-induced patients than in patients receiving VPA or other AEDs. CONCLUSIONS: Compared with children not receiving enzyme inducers, children younger than 4 years who receive concomitant enzyme-inducing AEDs need higher doses (milligrams per kilogram) to achieve comparable plasma TPM concentrations.
