Effects of Solriamfetol on Quality-of-Life Measures from a 12-Week Phase 3 Randomized Controlled Trial.

ABSTRACT: Rationale: Excessive daytime sleepiness in patients with obstructive sleep apnea is associated with substantial burden of illness.Objectives: To assess treatment effects of solriamfetol, a dopamine/norepinephrine reuptake inhibitor, on daily functioning, health-related quality of life, and work productivity in participants with obstructive sleep apnea and excessive daytime sleepiness as additional outcomes in a 12-week phase 3 trial (www.clinicaltrials.gov identifier NCT02348606).Methods: Participants (N?=?476) were randomized to solriamfetol 37.5, 75, 150, or 300 mg or to placebo. Outcome measures included the Functional Outcomes of Sleep Questionnaire short version, Work Productivity and Activity Impairment Questionnaire: Specific Health Problem, and 36-item Short Form Health Survey version 2. A mixed-effects model with repeated measures was used for comparisons with placebo.Results: Demographics, baseline disease characteristics, daily functioning, health-related quality of life, and work productivity were similar across groups. At Week 12, increased functioning and decreased impairment were observed with solriamfetol 150 and 300 mg (mean difference from placebo [95% confidence interval]) on the basis of Functional Outcomes of Sleep Questionnaire total score (1.22 [0.57 to 1.88] and 1.47 [0.80 to 2.13], respectively), overall work impairment (-11.67 [-19.66 to -3.69] and -11.75 [-19.93 to -3.57], respectively), activity impairment (-10.42 [-16.37 to -4.47] and -10.51 [-16.59 to -4.43], respectively), physical component summary (2.07 [0.42 to 3.72] and 1.91 [0.22 to 3.59], respectively), and mental component summary (150 mg only, 2.05 [0.14 to 3.96]). Common adverse events were headache, nausea, decreased appetite, and anxiety.Conclusions: Solriamfetol improved measures of functioning, quality of life, and work productivity in participants with obstructive sleep apnea and excessive daytime sleepiness. Safety was consistent with previous studies.Clinical trial registered with www.clinicaltrials.gov (NCT02348606).

Project description:Background: Despite the established relation between energy restriction and metabolic health, the most beneficial nutrient composition of a weight-loss diet is still subject of debate. Objectives: The aim of the study was to examine the additional effects of nutrient quality on top of energy restriction(ER). Methods: A parallel-designed 12-week 25%ER dietary intervention study was conducted. Participants aged 40-70 years with abdominal obesity were randomized over three groups: a 25%ER high nutrient quality diet (n = 40); a 25%ER low nutrient quality diet (n = 40); or a habitual diet (n = 30). Both ER diets were nutritionally adequate, the high nutrient quality ER diet was enriched in monounsaturated and n-3 polyunsaturated fatty acids, fiber, and plant protein and reduced in fructose. Before and after the intervention intra-hepatic lipids, body fat distribution, fasting and postprandial responses to a mixed meal shake challenge test of cardio-metabolic risk factors, lipoproteins, vascular measurements, and adipose tissue transcriptome were assessed. Results: The high quality ER diet (-8.4 ± 3.2) induced 2.1 kg more weight loss (P = 0.007) than the low quality ER diet (-6.3 ± 3.9), reduced fasting serum total cholesterol (P = 0.014) and plasma triglycerides (P < 0.001), promoted an anti-atherogenic lipoprotein profile and induced a more pronounced decrease in adipose tissue gene expression of energy metabolism pathways than the low quality ER diet. Explorative analyses showed that the difference in weight loss between both ER diets were specifically present in insulin sensitive subjects (HOMA-IR ≤ 2.5), in whom the high nutrient quality diet induced 3.9 kg more weight loss than the low nutrient quality diet. Conclusion: A high nutrient quality 25%ER diet is more beneficial for cardiometabolic health than a low nutrient quality 25%ER diet. Overweight insulin sensitive subjects may benefit more from a high than a low nutrient quality ER diet with respect to weight loss, due to potential attenuation of glucose-induced lipid synthesis in adipose tissue.

Project description:OBJECTIVES: Linaclotide is a minimally absorbed guanylate cyclase-C agonist. The objective of this trial was to determine the efficacy and safety of linaclotide in patients with irritable bowel syndrome with constipation (IBS-C). METHODS: This phase 3, double-blind, parallel-group, placebo-controlled trial randomized IBS-C patients to placebo or 290 μ g oral linaclotide once daily in a 12-week treatment period, followed by a 4-week randomized withdrawal (RW) period. There were four primary end points, the Food and Drug Administration ’ s (FDA ’ s) primary end point for IBS-C (responder: improvement of ≥ 30 % in average daily worst abdominal pain score and increase by ≥ 1 complete spontaneous bowel movement (CSBM) from baseline (same week) for at least 50 % of weeks assessed) and three other primary end points, based on improvements in abdominal pain and CSBMs for 9 / 12 weeks. Adverse events (AEs) were monitored. RESULTS: The trial evaluated 800 patients (mean age = 43.5 years, female = 90.5 % , white = 76.9 % ). The FDA end point was met by 136 / 405 linaclotide-treated patients (33.6 % ), compared with 83 / 395 placebo-treated patients (21.0 % ) ( P < 0.0001) (number needed to treat: 8.0, 95 % confidence interval: 5.4, 15.5). A greater percentage of linaclotide patients, compared with placebo patients, reported for at least 6 / 12 treatment period weeks, a reduction of ≥ 30 % in abdominal pain (50.1 vs. 37.5 % , P = 0.0003) and an increase of ≥ 1 CSBM from baseline (48.6 vs. 29.6 % , P < 0.0001). A greater percentage of linaclotide patients vs. placebo patients were also responders for the other three primary end points ( P < 0.05). Significantly greater improvements were seen in linaclotide vs. placebo patients for all secondary end points ( P < 0.001). During the RW period, patients remaining on linaclotide showed sustained improvement; patients re-randomized from linaclotide to placebo showed return of symptoms, but without worsening of symptoms relative to baseline. Diarrhea, the most common AE, resulted in discontinuation of 5.7 % of linaclotide and 0.3 % of placebo patients. CONCLUSIONS: Linaclotide significantly improved abdominal pain and bowel symptoms associated with IBS-C for at least 12 weeks; there was no worsening of symptoms compared with baseline following cessation of linaclotide during the RW period.

Project description:Rationale: Primary treatment of obstructive sleep apnea can be accompanied by a persistence of excessive sleepiness despite adherence. Furthermore, effectiveness of sleep apnea treatment is limited by poor adherence. Currently available pharmacologic options for the treatment of sleepiness in this population are limited. Objectives: To evaluate the efficacy and safety of solriamfetol (JZP-110), a selective dopamine and norepinephrine reuptake inhibitor with robust wake-promoting effects, for the treatment of excessive sleepiness in participants with obstructive sleep apnea with current or prior sleep apnea treatment. Methods: This was a double-blind, randomized, placebo-controlled, parallel-group, 12-week trial comparing solriamfetol, 37.5, 75, 150, and 300 mg, with placebo. Measurements and Main Results: Of 476 randomized participants, 459 were included in the prespecified efficacy analyses. Coprimary endpoints (Maintenance of Wakefulness Test sleep latency and Epworth Sleepiness Scale score) were met at all solriamfetol doses (P < 0.05), with dose-dependent effects observed at Week 1 maintained over the study duration. All doses except 37.5 mg resulted in higher percentages of participants reporting improvement on Patient Global Impression of Change (key secondary endpoint; P < 0.05). Adverse events were reported in 47.9% of placebo- and 67.9% of solriamfetol-treated participants; five participants experienced serious adverse events (two [1.7%] placebo, three [0.8%] solriamfetol); none were deemed related to study drug. The most common adverse events with solriamfetol were headache (10.1%), nausea (7.9%), decreased appetite (7.6%), anxiety (7.0%), and nasopharyngitis (5.1%). Conclusions: Solriamfetol significantly increased wakefulness and reduced sleepiness in participants with obstructive sleep apnea and excessive sleepiness; most adverse events were mild or moderate in severity.

Project description:Hyperglucagonemia contributes to hyperglycemia in patients with type 1 diabetes (T1D); however, novel therapeutics that block glucagon action could improve glycemic control. This phase 2 study evaluated the safety and efficacy of volagidemab, an antagonistic monoclonal glucagon receptor (GCGR) antibody, as an adjunct to insulin therapy in adults with T1D. The primary endpoint was change in daily insulin use at week 12. Secondary endpoints included changes in hemoglobin A1c (HbA1c) at week 13, in average daily blood glucose concentration and time within target range as assessed by continuous blood glucose monitoring (CGM) and seven-point glucose profile at week 12, incidence of hypoglycemic events, the proportion of subjects who achieve HbA1c reduction of ≥0.4%, volagidemab drug concentrations and incidence of anti-drug antibodies. Eligible participants (n = 79) were randomized to receive weekly subcutaneous injections of placebo, 35 mg volagidemab or 70 mg volagidemab. Volagidemab produced a reduction in total daily insulin use at week 12 (35 mg volagidemab: -7.59 units (U) (95% confidence interval (CI) -11.79, -3.39; P = 0.040 versus placebo); 70 mg volagidemab: -6.64 U (95% CI -10.99, -2.29; P = 0.084 versus placebo); placebo: -1.27 U (95% CI -5.4, 2.9)) without meeting the prespecified significance level (P < 0.025). At week 13, the placebo-corrected reduction in HbA1c percentage was -0.53 (95% CI -0.89 to -0.17, nominal P = 0.004) in the 35 mg volagidemab group and -0.49 (95% CI -0.85 to -0.12, nominal P = 0.010) in the 70 mg volagidemab group. No increase in hypoglycemia was observed with volagidemab therapy; however, increases in serum transaminases, low-density lipoprotein (LDL)-cholesterol and blood pressure were observed. Although the primary endpoint did not meet the prespecified significance level, we believe that the observed reduction in HbA1c and tolerable safety profile provide a rationale for further randomized studies to define the long-term efficacy and safety of volagidemab in patients with T1D.

Project description:BackgroundPhysical inactivity and sarcopenia are two important predictors associated with increased morbidity and mortality in patients with cirrhosis. At present, the benefit of a home-based exercise training program is not well established in cirrhotic patients. The main objective of this study was to evaluate the effect of a 12-week home-based exercise training program on aerobic capacity in cirrhotic patients.MethodsThis is a randomized controlled study. Patients with compensated cirrhosis were randomized by a block of 4 with concealed allocation to the home-based exercise training (n = 20) or control (n = 20). Both groups received protein supplementation (9 g/day) for 12 weeks. The home-based exercise training program included several aerobic/isotonic moderate-intensity continuous training exercises for 40 min per session, at least four times a week, with a total duration of 12 weeks. The heart rate was continuously monitored using a Garmin® watch. In the control group, patients received exercise instruction without active encouragement and continuous monitoring. The primary outcome was a change in the 6-min walk test from baseline. Secondary outcomes were the difference in thigh muscle thickness, liver stiffness, spleen stiffness, and quality of life.ResultsA total of 40 patients were enrolled prospectively. The mean age was 56.3 ± 7.8 years, with a male predominance of 65%. The mean body mass index was 25.23 ± 3.0 kg/m2, and all were Child-Pugh A. Chronic hepatitis B or C was the primary cause of cirrhosis. The baseline values were a 6-min walk test of 475 ± 70 m, liver stiffness of 15.3 ± 9.3 kPa, spleen stiffness of 29.8 ± 21.7 kPa, and thigh muscle thickness (average compression index) of 0.64 ± 0.2 cm/m2. All baseline characteristics between the two groups were not different except the mean muscle mass which was significantly higher in the home-based exercise training group (p = 0.03, 95% CI 0.01 to 0.17). At the end of the study, no significant difference in the 6-min walk test was observed (p = 0.36, 95% CI -15.5 to 41.7). Liver stiffness measurement significantly improved in both groups, but no significant difference between groups was demonstrated (p = 0.77, 95% CI -1.3 to 1.8). Thigh muscle thickness was not different between groups. The fatigue domain of the quality of life index was significantly improved in the home-based exercise training group compared with the control group (p = 0.05, 95% CI 0.00 to 0.67). No adverse events occurred in a home-based exercise training program.ConclusionsA 12-week moderate-intensity home-based exercise training program in compensated cirrhotic patients significantly improved the fatigue domain of the quality of life index without an increase in adverse events. However, no benefit in terms of aerobic capacity, thigh muscle mass, liver stiffness, and spleen stiffness was demonstrated.Trial registrationThai Clinical Trials Registry number TCTR20190926002, 26/09/2019 (Retrospectively registered).
