The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-06882961) for the potential treatment of obesity. The study will compare the experiences of participants taking the study medicine (PF-06882961) to those of participants who take placebo (a look- alike substance that contains no active study medicine). The aim is to measure the body's response to the study medicine, including any changes in participants' body weight, waist and hip measurements, how well they tolerate the study medicine, and to measure levels of the study medicine in participants' blood. This study is seeking participants who have obesity, who do not have diabetes and who have had a stable body weight and not participated in a formal weight loss program in the 90 days before the study. The study medicine or placebo will be taken as tablets by mouth 2 times a day (1 time in the morning and 1 time in the evening). There are 3 groups of participants (called cohorts) in this study. For participants in Cohorts 1 and 2, total study participation will be about 9 months, with 15 planned study visits (14 visits to the study clinic and 1 telephone call). For participants in Cohort 3, total study participation will be about 10 months, with 21 planned study visits (12 visits to the study clinic and 9 telephone calls).
1. Study Objective <Part 1> To evaluate the safety and pharmacokinetic/pharmacodynamic characteristics of HSG4112 after multiple oral administration in healthy female subjects. <Part 2> To evaluate the safety and pharmacokinetic/pharmacodynamic characteristics of HSG4112 after multiple oral administration in obese subjects. 2. Background The previous phase 1 clinical trials investigating HSG4112 only included healthy male subjects, and food effect was observed in theses studies - the plasma exposure to HSG4112 following administration under fed conditions was approximately 2.5 times higher compared to the exposure following administration under fasted conditions. Therefore, this study is designed to evaluate the safety of HSG4112 in healthy female subjects and obese subjects following the administration of HSG4112 under fed conditions. 3. Study Design and Plan <Part 1> This study is a dose block-randomized, double-blind, placebo-controlled, multiple dosing, phase 1 clinical study. A unique randomization number will be assigned to each subject deemed eligible to participate in the study based on the inclusion/exclusion criteria. Each subject will be randomized to one of the two dose groups. In each dose group, 8 subjects will be randomized to receive HSG4112 and 2 subjects will be randomized to receive placebo. The subjects will be studied in a double-blind manner and will receive the investigational product (i.e., HSG4112 or placebo) via once-daily oral administration for 14 consecutive days. After the Post-Study Visit of the last volunteer in the 480 mg dose group, the Investigator will review all the available safety data in a blinded manner to ensure if it is safe to proceed with the 720 mg dose group. In order to evaluate safety and tolerability, assessments, such as vital signs, 12-lead ECG, laboratory test, pregnancy test, physical examination, and adverse event monitoring will be performed. Blood samples will be collected to evaluate the pharcokinetic/pharmacodynamic characteristics of HSG4112. <Part 2> This study is a dose block-randomized, double-blind, placebo-controlled, multiple dosing, phase 1 clinical study.

The use of dietary amino acids has been explored for therapeutic and safety intervention of obesity and obesity-induced dysfunction. In particular, 3 molecules have been shown to be effective both in the animal model and in humans, in promoting the loss of fat mass, specifically visceral adipose tissue, and in maintaining free fat mass: arginine, glutamine and leucine (and its metabolite beta hydroxy methyl butyrate, HMB). The aim of this study was to evaluate the efficacy in terms of fat mass, in particular Visceral Adipose Tissue reduction, as primary end point, in obese patients following the administration of specific food for special medical purposes (FSMP) for muscle recovery, consisting of arginine, glutamine and HMB. The secondary end point is the evaluation of skin state, by a validate self-reported questionnaire survey to assess skin, after 4- weeks intake of this FSMP.
The primary objective of the trial is to establish the effects of dietary sulfur amino acid (SAA) restriction on body weight, body composition and energy expenditure in humans.
This is a prospective, clinical, multicentre study aimed to collect biological samples and study microbiota from subjects with morbid obesity, metabolically healthy obesity and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological) The study will allow to: - Provide biological samples (faeces, saliva, blood, urine) from healthy volunteers and patients to the first Italian microbiota biobank; - Study microorganisms using different in vitro and in vivo techniques; - Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.
Obesity related ailments, such as cardiovascular diseases (CVD) and metabolic disorders are major causes of death in the Western World. This trial may result in improved prevention, diagnosis and treatments for obesity and obesity-related disorders. Published data show that if a weight is carried by a rodent, this animal will lose body weight and gain an improved glucose control. Recently published data further show comparable results in humans when carrying an additional weight. The investigators aim to confirm and further investigate these findings in humans. The investigators plan to let obese participants carry weight vests and monitor their change in body weight. The investigators will also measure food intake, physical activity, energy expenditure, body composition, abdominal fat and heart rate variability. This to further examine the potential beneficial effects of loading and the mechanism of action.
Rice germ (RG) may be a safe and effective dietary supplement for obesity in menopause, considering its high protein content and considerable amounts of essential amino acids, good fatty acids, and fiber. This pilot randomized, blinded, parallel group, placebo-controlled pilot trial investigated the effectiveness of four weeks of RG supplementation (25 g twice a day) on body composition, measured by Dual Energy X-Ray Absorptiometry (DXA), as primary outcome, and metabolic parameters, amino acid profiles and satiating capacity, as secondary outcomes, in obese postmenopausal women following a tailored hypocaloric diet (25-30% less than daily energy requirements). Twenty-seven women were randomly assigned to the supplemented group (14) or placebo group (13). There was a significant interaction between time and group for body mass index (BMI) (p<0.0001), waist (p=0.002), and hip circumference (p=0.01), total protein (0.008), albumin (0.005), Homeostasis Model Assessment index (p=0.04), glycine (p=0.002), glutamine (p=0.004), and histidine (p=0.007). Haber's means over time showed a clearly greater feeling of satiety for the supplemented compared to the placebo group. These findings indicate that RG supplementation in addition to a tailored diet counterbalanced the metabolic changes typical of menopause, with improvements in BMI, body composition, insulin resistance, amino acid profiles and satiety.
The primary objective was to investigate the effectiveness of interval training and to evaluate the best available method for measuring body composition and functional capacity. Thirty obese subjects consecutively voluntarily participated in the current study. They ranked sedentary according to their level of activity (≥ 30-minute moderate physical activity 3days/wk). The training sessions were divided into the warm-up phase, training phase and a cool-down phase. The training programs were completed 3days/week for 12 weeks. Body composition was calculated by skinfold thickness method and bio-impedance before and after training. Similarly, aerobic capacities were measured by lactate threshold testing and by Astrand submaximal testing.
1. Normal diet：Starting from May 20, 2018, the subjects will eat a normal diet for 4 days, with no restriction on calories and food types. The subjects are required to record their daily diet and dietary intake of calories. 2. Fast diet of High control ：From May 24, 2018, the method of fast diet was adopted on alternate days. According to the dietary records of normal diet, the normal caloric intake of each subject was calculated. Fast diet was carried out according to 2/3, 1/2, 1/3 and 1/4 of the original normal caloric intake.Each caloric stage last for 4 days, and the total cycle of fast diet was 31 days. 3. Fast diet of Low control ：After the intervention of fast diet of high control, the subjects were allowed to continue the diet fast diet every other day. It was suggested that the daily caloric intake was 600kal/ day for males and 500kal/ day for females.
