IQP-VV-102, a Novel Proprietary Composition for Weight Reduction: A Double-Blind Randomized Clinical Trial for Evaluation of Efficacy and Safety.

ABSTRACT: The individual ingredients in IQP-VV-102 have demonstrated promising effects in reducing sugar and starch digestion, which potentially leads to weight loss. The trial objective was to evaluate the safety and efficacy of IQP-VV-102 in reducing body weight in overweight and obese subjects. 120 overweight and obese individuals aged 18 to 60 years were randomly assigned to 2 treatment arms (IQP-VV-102 and placebo). The trial was conducted in 2 study centres in Berlin, Germany. The primary efficacy analysis was conducted on 117 subjects (IQP-VV-102: N = 54; placebo: N = 59), comparing the weight loss effect at baseline and 12 weeks after randomization. There was a statistically significant reduction in mean body weight of 3.29?kg (SD 2.30) in the IQP-VV-102 group compared to 0.83?kg (SD 2.00) in the placebo group (p < 0.001). There were no serious or product-related adverse events that were reported over the combined period of 14 weeks. The findings suggested that IQP-VV-102 is effective and safe in body weight reduction in overweight and obese individuals in the short term. The study is registered under clinicaltrials.gov as NCT01681069.

Project description:The effect of the novel IQP-AE-103 (proprietary combination of dehydrated okra powder and inulin) on body weight reduction and the association with changes in microbiota composition were investigated in a double-blind, randomized, placebo-controlled trial. A total of seventy-two overweight or moderately obese subjects with a body mass index of ≥25 and <35 kg/m2 were randomly allocated to receive IQP-AE-103 or placebo; each group received two IQP-AE-103 or placebo capsules three times daily, respectively. Body weight, body fat, waist circumference, and hip circumference were measured, and fecal samples were collected at baseline and after 12 weeks of intervention. Using 16S rRNA gene sequencing on the fecal samples, the microbiota dissimilarity, diversity, and differences in relative abundance between or within groups were analyzed. At the end of the study, body weight was significantly reduced in the IQP-AE-103 group compared with the placebo group, 5.16 ± 2.39 kg vs. 0.97 ± 2.09 kg (p < 0.001). Subjects from the IQP-AE-103 group who achieved a reduction of ≥5% of total body weight from baseline (hereafter referred to as 5% responders or IQP5) had a mean body weight reduction of 6.74 ± 1.94 kg, significantly greater than the placebo group (p < 0.001). Using Lefse and statistical analysis, subjects in the IQP-AE-103 group had a significantly lower relative abundance of Firmicutes than the placebo group (p < 0.05) after 12 weeks of intervention. The 5% responders from the IQP-AE-103 group had a remarkable 4.6-fold higher relative abundance of Akkermansia muciniphila than the placebo group (p < 0.05). As the significant differences between groups were only observed post-intervention, the overall differences in microbiota profile suggest that the weight loss in overweight and moderately obese subjects who consumed IQP-AE-103 for 12 weeks is accompanied by a positive change in microbiota composition. These changes might be linked to the beneficial effects of microbiome modulations in alleviating obesity and metabolic syndrome. To the best of our knowledge, we are the first to report over-the-counter (OTC) supplementation that results in both significant changes in weight and favorable shifts on the subject microbiota profile. The trial is registered under ClinicalTrials.gov Identifier no. NCT03058367.

Project description:ObjectiveThe purpose of this study was to explore the clinical benefit and tolerability of IQP-AO-101 in healthy subjects with sleep complaints.MethodsThis double-blind, randomized, placebo-controlled trial involved fifty subjects with sleep complaints. Subjects with a Pittsburgh Sleep Quality Index (PSQI) score between 6 and 15 were randomized to receive either IQP-AO-101 or placebo for 6 weeks, following a run-in period of one week. Sleep parameters were assessed at baseline and after 1, 4, and 6 weeks using the modified Athens Insomnia Scale (mAIS). Subjects were also instructed to wear an activity tracker and keep a sleep diary during the study. Other questionnaires administered were the Frankfurt Attention Inventory (FAIR-2) and the Profile of Mood States (POMS-65). Blood samples for safety laboratory parameters were taken before and at the end of the study.ResultsAfter 6 weeks, subjects who consumed IQP-AO-101 reported significant improvements in mAIS scores compared with placebo, including mAIS total score (11.76 ± 6.85 vs 4.00 ± 4.80; p < 0.001); night parameters composite score (5.20 ± 3.80 vs 2.04 ± 3.16; p = 0.001); and day parameters composite score (6.56 ± 4.10 vs 1.96 ± 2.65; p < 0.001). All individual parameters (Items 1 to 8) were also significantly improved from baseline after 6 weeks of IQP-AO-101 intake. Analysis of variance with baseline values as covariates showed statistically significant improvements across all individual parameters for IQP-AO-101 when compared to placebo. The measurements using the activity tracker, sleep diary, FAIR-2, and POMS did not reveal any significant differences between groups. No adverse effects related to the intake of IQP-AO-101 were reported. Tolerability was rated as very good by all the subjects and by the investigator for all cases.ConclusionsIn this study, IQP-AO-101 was well tolerated and efficacious for promoting sleep and enhancing daytime performance in subjects with moderate sleep disturbances.Clinical trial registrationThis trial is registered with ClinicalTrials.gov, no. NCT03114696.

Project description:IntroductionThe aim of this study was to evaluate the benefit and tolerability of two dosages of a proprietary flaxseed mucilage (IQP-LU-104) in reducing body weight in overweight and moderately obese individuals.MethodsIn a double-blind, randomized, placebo-controlled, bi-center trial, 108 participants (body mass index [BMI] 25-<35 kg/m2) were randomly allocated to receive either IQP-LU-104 high dose (104HD), IQP-LU-104 low dose (104LD), or placebo. Participants were instructed to consume 1 sachet of the investigational product (containing IQP-LU-104 or matching placebo) before or with main meals twice daily and to follow a balanced but hypocaloric diet (20% reduction of individual's daily energy requirements) for 12 weeks. At week 0 (baseline), and weeks 4, 8, and 12 of the intervention periods, the participants' body weight, BMI, body fat composition, and waist and hip circumferences were measured. Blood samples were collected for safety assessment at screening visit (week -2) and at the end of the study. Adverse events were assessed by the investigators through interviewing the participants and were recorded at every visit post screening.ResultsAt the end of the 12-week study, body weight reduction was greater in the 104HD group (4.96 ± 1.89 kg, p < 0.001 vs. placebo) and 104LD group (3.70 ± 2.57 kg, p < 0.001 vs. placebo) compared to the placebo group (1.33 ± 2.05 kg). 68% and 46% of participants in the 104HD group (p < 0.001 vs. placebo) and 104LD group (p = 0.002 vs. placebo), respectively, experienced at least 5% weight loss, compared to 9% of participants in the placebo group. Significant decreases in waist and hip circumferences were observed in both the 104HD and 104LD groups compared to the placebo group (each p < 0.001). 104HD group had significantly higher reduction in body fat mass (4.25 ± 5.86 kg) than the placebo group (1.06 ± 3.20 kg) (p = 0.002). Respiratory tract infections and gastrointestinal symptoms were the main adverse events reported and none of the adverse events were related to the intake of IQP-LU-104.ConclusionResults demonstrated IQP-LU-104 is safe and efficacious in body weight reduction at both dosages in overweight and moderately obese individuals.

Project description:Chitosan is a dietary fibre which acts by reducing fat absorption and thus used as a means for controlling weight. Weight loss clinical trial outcomes, however, have contradictory results regarding its efficacy. The primary objective of the present study was to evaluate the efficacy and safety of a chitosan from fungal origin in treatment of excess weight in the absence of dietary restrictions.A phase IV, randomised, multicentre, single-blind, placebo-controlled, clinical study was conducted by administering chitosan capsules (500 mg, five/day) and indistinguishable placebo capsules as daily supplements to 96 overweight and obese subjects for 90 days. The study participants were divided in 2:1 ratio to receive either chitosan (n = 64) or placebo (n = 32). Efficacy was assessed by measuring body weight, body composition parameters, anthropometric measurements, HbA1C level and lipid profile at day 45 and day 90. Also, short form-36 quality of life (QoL) questionnaire was assessed to evaluate improvement in life-style and dietary habits were recorded for calorie intake. Safety was assessed by evaluating safety parameters and monitoring adverse events.The mean changes in body weight were -1.78 ± 1.37 kg and -3.10 ± 1.95 kg at day 45 and day 90 respectively in chitosan group which were significantly different (p < 0.0001) as compared to placebo. BMI was decreased by10.91 fold compared to placebo after 90 day administration. In concert with this, there was also reduction in body composition and anthropometric parameters together with improvement in QoL score. Chitosan was also able to reduce HbA1C levels (below 6 %) in subjects who had initial higher values. The mean caloric intake shows that there was no change in dietary habits of subjects in both groups. Lipid levels were unaffected and all adverse events were mild in nature and unrelated to study treatment.Chitosan from fungal origin was able to reduce the mean body weight up to 3 kg during the 90 day study period. Together with this, there was also improvement in body composition, anthropometric parameters and HbA1C, reflecting overall benefits for the overweight individuals. Additionally, there was also improvement in QoL score. It was safe and well tolerated by all subjects.CTRI/2014/08/004901.

Project description:Naltrexone, an opioid antagonist, may facilitate reduction in drinking among young adults. We compared the efficacy and safety of naltrexone administered daily plus targeted dosing with placebo to reduce drinking in young adults who engage in heavy drinking.A randomized, double-blind, placebo-controlled study was conducted in an outpatient research center in March 2008-January 2012. Participants were aged 18-25 years and reported ? 4 heavy drinking days in the prior 4 weeks. Interventions included naltrexone 25 mg daily plus 25 mg targeted (at most daily) in anticipation of drinking (n = 61) or daily/targeted placebo (n = 67). All participants received a personalized feedback session and brief counseling every other week. Primary outcomes were percent heavy drinking days and percent days abstinent over the 8-week treatment period. Secondary outcomes included number of drinks per drinking day and percentage of days with estimated blood alcohol concentration (BAC) levels ? 0.08 g/dL.Of 140 randomized patients, 128 began treatment, comprising the evaluable sample. During treatment, percent heavy drinking days (naltrexone: mean = 21.60, SD = 16.05; placebo: mean = 22.90, SD = 13.20) (P = .58) and percent days abstinent (naltrexone: mean = 56.60, SD = 22.52; placebo: mean = 62.50, SD = 15.75) (P = .39) did not differ by group. Naltrexone significantly reduced the number of drinks per drinking day (naltrexone: mean = 4.90, SD = 2.28; placebo: mean = 5.90, SD = 2.51) (P = .009) and percentage of drinking days with estimated BAC ? 0.08 g/dL (naltrexone: mean = 35.4, SD = 28.40; placebo: mean = 45.7, SD = 26.80) (P = .042). There were no serious adverse events. Sleepiness was more common with naltrexone.Naltrexone did not reduce frequency of drinking or heavy drinking days, but reduced secondary measures of drinking intensity. While effects were modest, the risk-benefit ratio favors offering naltrexone to help young adult heavy drinkers reduce the amount of alcohol they drink.ClinicalTrials.gov identifier: NCT00568958.
