The purpose of this study is to assess the safety, efficacy, and tolerability of deucravacitinib (BMS-986165) compared with placebo in participants with active discoid and/or subacute cutaneous lupus erythematosus (DLE/SCLE). This study will also assess if deucravacitinib is biologically active and potentially effective in the treatment of participants with moderate to severe DLE/SCLE with or without systemic lupus erythematosus (SLE) that is not well controlled with standard of care therapy.
NCT03104374
This is a Phase 3 multicenter study that included two periods. Period 1 was designed to compare the safety, tolerability, and efficacy of upadacitinib 15 mg once daily (QD) and 30 mg QD versus placebo in participants with moderately to severely active Psoriatic Arthritis (PsA) who had an inadequate response to Biological Disease Modifying Anti-Rheumatic Drug (bDMARDs). Period 2 evaluated the safety, tolerability and efficacy of upadacitinib 15 mg QD and 30 mg QD in subjects with PsA who completed Period 1.
NCT01773928
The purpose of this study is to determine if a Vero cell-derived trivalent seasonal influenza vaccine produced by the modified manufacturing process: 1. induces immune responses comparable to that produced by the current manufacturing process 2. has an acceptable safety profile compared to a licensed trivalent seasonal influenza vaccine 3. demonstrates consistency of immune response among three different lots.
NCT01850992
The purpose of this study is to identify the mechanism(s) by which OSA exacerbates the age-linked decline in systemic testosterone concentrations by conducting a randomized order sham-controlled crossover study that dynamically evaluates the entire hypothalamic-pituitary testicular axis across a wide age range.
NCT04037605
The purpose of this study is to 1) determine how hypothalamic-pituitary-adrenal axis (HPA axis) activation occurs with sleep restriction and 2) evaluate how hypothalamic-pituitary-gonadal axis (HPG axis) deactivation occurs with sleep restriction. The investigator will also examine the cognitive function associated with sleep restriction, including food intake and food cravings.
NCT02256865
The purpose of this study is to study the effects of sleep restriction on the production of two hormones, cortisol and testosterone. The investigators aim to show that changing these hormones leads to insulin resistance, which is an important cause of type 2 diabetes mellitus. The investigators may also study the effect of sleep restriction on your food intake and cravings, mood, inflammation, metabolism (including bone), and other hormones. Inflammation is your body's response to stress and injury. Bone metabolism is a process of how your body regenerates (renews) new bone cells and removes old bone cells. Hormones are natural substances (materials) that are produced in the body and that influences (effects) the way the body grows or develops.
NCT06680375
This study will evaluate the reactogenicity, safety, and immune response of Flu Seasonal/SARS-CoV-2 mRNA (mRNA Flu/COVID-19) combination vaccine. The flu portion will target multiple strains of the flu virus, while the COVID-19 part will focus on the spike protein of the SARS-CoV-2 virus. Both parts of this vaccine have been tested individually before. This will be the first study to test the combined vaccine in humans in healthy adult participants.

NCT03944616
Diet beverages sweetened with artificial sweeteners occupy a unique category in the food environment as they are a source of intensely sweet taste with no calories. Diet beverages are the single largest contributor to artificial sweetener intake in the U.S. diet, and people with diabetes are the highest consumers of diet beverages, tending to consume them as a replacement for dietary sources of sugar, especially in place of sugar-sweetened beverages. This behavior has been endorsed by dietetic and scientific organizations, and diet beverages are marketed as being synonymous with better health, suitable for weight loss, and thus advantageous for diabetes control. The underlying public health concern is that there are few data to support or refute the benefit or harm of habitual diet beverage consumption by people with diabetes; therefore randomized trials with relevant outcomes must be conducted because they would address many limitations of previous research and have major implications for dietary recommendations on diet beverage intake and primary and secondary prevention of chronic disease. To begin addressing this important scientific gap the investigators are testing the effect of diet beverage intake on diabetes control parameters in free-living adults with type 2 diabetes in a randomized, two arm parallel trial with a run-in period of 2-weeks and an active intervention period of 24-weeks. This study will recruit 200 patients with type 2 diabetes who are usual consumers of commercial diet beverages and randomize them to receive and consume either: 1) A commercial diet beverage of choice (3 servings or 24 oz. daily); or 2) Unflavored bottled water of choice (sparkling or plain) (3 servings or 24 oz. daily). The primary outcome will be a central measure of clinical diabetes control in glycated hemoglobin (HbA1c). The study will also measure the nature and magnitude of glycemic excursions via continuous glucose monitors, as well as clinical markers of cardiometabolic risk and kidney function. Lastly, investigators will measure plausible mechanisms whereby diet beverage intake may alter risk by assessing the effect of diet beverage intake on the functional composition of the gut microbiome via stool samples and comprehensive metabolomics, satiety hormones, as well as usual dietary intake, and upstream behavioral pathways which may inform dietary intake patterns.
NCT05701995
The purpose of this study is to evaluate the effect of deucravacitinib on quality of life (QoL) in participants with plaque psoriasis in a community setting.
NCT06996301
Complicated urinary tract infections (cUTIs) often lead to the overuse of empiric antibiotics, risking inappropriate treatment and contributing to antimicrobial resistance. This randomized, multi-center, investigator-blinded clinical trial is the first global head-to-head comparison of molecular diagnostic testing (Polymerase Chain Reaction : PCR) versus conventional culture and sensitivity (C\&S) for managing cUTIs in adults. Conducted across six U.S. clinical sites, the study aimed to evaluate the clinical utility of PCR-guided treatment relative to C\&S-guided care. Eligible adult patients were randomized 1:1 into two diagnostic arms-PCR or C\&S-after providing informed consent. Urine samples were collected before randomization, tested by both methods, but clinicians remained blinded to the comparator results to avoid bias. Treatment decisions were based only on the assigned test results. Urine was collected at baseline (Day 1) and at end-of-study (Day 28). Samples were processed centrally: the PCR method (DocLab UTM 2.0) detected 28 uropathogens and 16 antibiotic resistance gene classes; C\&S testing quantified bacterial loads and assessed antimicrobial susceptibility using standard thresholds (≥10⁵ CFU/mL). The primary endpoint was the number of patients in each arm achieving a Favorable Clinical Outcome (FCl) at Day 28, defined as either: * Clinical Cure (complete symptom resolution requiring no further antibiotics), or * Clinical Improvement (partial symptom resolution without new symptoms or IV antibiotics). Secondary endpoints included: * Microbiological eradication at EOS (via C\&S and PCR). * Clinician satisfaction with diagnostic usefulness and result clarity. * Turnaround time comparison between PCR and C\&S. * Concordance analysis of test results between PCR and C\&S. * FCl rates in discordant cases, where PCR and C\&S results disagreed.
