There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study intends to investigate the use of high-dose Vitamin D3 plus a multivitamin in the prevention of cluster headache attacks. Participants can be enrolled anywhere in the United States that has access to one of our participating labs (for blood work - anticipated to be available in most of the USA). The study may include: - Screening: Participants may be interviewed, examined, fill out surveys, and get blood testing - Week 1: baseline period (no added medications - to establish a baseline) - Weeks 2-4: double-blinded experimental period - participants receive either 1) high-dose Vitamin D3 + multivitamin, or 2) placebo + multivitamin. Participants also fill out a survey and have blood testing. - Weeks 5-7: open-label period - ALL participants receive high-dose Vitamin D3 + multivitamin. Participants also fill out a survey and may have blood testing. Specifically, our primary outcome is the change from baseline to experimental weeks 1-3 in the frequency of cluster headache attacks between placebo and high-dose vitamin D. Specific primary and secondary outcomes are listed below.
Gestational diabetes (GDM) is a condition of high blood glucose (or "blood sugar") during pregnancy. GDM can cause harmful short-term and long-term health effects for mom and baby. Diet therapy is an effective way to achieve normal blood glucose for women with GDM, but the best diet is unknown. Diet strategies that improve blood glucose in GDM and that patients can follow are needed for better clinical care. In studies of non-pregnant individuals with diabetes, eating a high fat/protein breakfast as the only dietary change was enough to improve glucose control. Because highest blood glucose readings in GDM usually occur after breakfast, a high fat/protein breakfast could also improve glucose control in GDM. In this study, two dietary strategies for improving blood glucose will be compared. Ten women newly diagnosed with GDM (<30 weeks in pregnancy) will be enrolled in a 12-day cross-over controlled feeding study with a high fat/protein breakfast, which is named a 'Macro-Optimized Diet' (MOD) or standard care diet (SC). In other words, subjects will have all food provided to them, and they will consume each diet for a few days while researchers monitor their blood glucose. Most nutrition aspects of the two diets will be similar, but the MOD diet will vary the timing of eating carbohydrate, protein, and fat to achieve fewer carbs at breakfast. After the 12-day controlled feeding period, participants will continue one of the study diets (as randomized) until delivery. During this time, research team dietitians will provide personalized nutrition education to support GDM self-management. The study will evaluate whether the diet is acceptable to women with GDM and their clinic providers. Data to be collected include blood glucose data, patient and provider feedback on diet acceptability, weight gain, the number of participants who are prescribed blood glucose control medications, and infant weight. These data will be used to evaluate trends pointing to whether one diet is more effective.
The primary objective of this study is to evaluate the safety and tolerability of V590 versus placebo and to assess the immunogenicity of V590 on Day 28. The primary hypothesis is that at least one well-tolerated dose of V590 increases the geometric mean titers (GMTs) of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike serum neutralizing antibody, as measured by plaque reduction neutralization test (PRNT), compared to placebo.
To evaluate and compare the efficacy of two dosing regimens of oral edaravone in subjects with amyotrophic lateral sclerosis (ALS) based on the change in ALS Functional Rating Scale- Revised (ALSFRS-R) score from baseline up to Week 48:
Early Basal Insulin Administration in Adult Diabetic Ketoacidosis Management
As the global and pandemic spread of the novel coronavirus (SARS-CoV-2, COVID-19) continues, many knowledge gaps remain with regard to the epidemiology and transmission of infection, as well as the normal immunological responses after viral exposure. Cincinnati had its first confirmed case of COVID-19 on March 14, 2020, and despite extensive shelter-in-place and social distancing efforts, community spread continues at over 150-200 new cases per week. As new residents and fellows arrive in July 2020 to Cincinnati Children's Hospital Medical Center (CCHMC), many of whom come from metropolitan areas across the country, it is imperative that investigators determine the current prevalence of infection, measure the cumulative incidence of infection over the next 12-24 months, investigate the normal antibody patterns after infection, and help elucidate what constitutes a protective immunological response. The investigators have a unique but time-limited opportunity to optimally track the epidemiology and natural history of SARS-CoV-2 infection among trainees at CCHMC, including risk factors for transmission and immunological recovery. SCREEN will investigate epidemiological and immunological features of SARS-CoV-2 virus infection within the cohort of CCHMC residents and fellows who have patient contact. By collecting and analyzing weekly serial samples for SARS-CoV-2 (nasal swab for virus by PCR) and monthly serological exposure (serum antibodies by ELISA), the investigators will determine the prevalence and cumulative incidence of infection by SARS-CoV-2; the investigators will also document the antibody responses over time and identify cases of apparent viral recrudescence or re-infection.
Background: Bile duct cancer is cancer of the slender tubes of the biliary tract. These tubes carry bile through the liver. Such cancer tumors often have an abnormal or mutated gene. Researchers think a mix of drugs can slow the progression of gene-mutated cancers of the biliary tract. Objective: To see if using a combination of trametinib and hydroxychloroquine (HCQ) increases the period of time it takes for a person s bile tract carcinoma (BTC) to get worse. Eligibility: Adults age 18 and older with BTC. Design: Participants will be screened with a physical exam, medical history, and cancer history. Their ability to do their normal activities will be assessed. They will have blood and urine tests. They will give a tumor sample. They will have heart tests. They may talk with a heart doctor. They may have an eye exam. They may have a tuberculosis test. They will have computer tomography (CT) scans of the chest, abdomen, and pelvis. They may have magnetic resonance imaging (MRI) scans of the chest, abdomen, pelvis. Participants will repeat some screening tests throughout the study. Participants will take HCQ and trametinib tablets by mouth daily in 28-day cycles. They will have study visits once a month. They will take the drugs until they have bad side effects or the drugs stop working. Participants will have one more tumor biopsy during the treatment. They will have blood taken often. One month after treatment ends, participants will have a safety follow-up visit. Then they will be called or emailed every 6 months for the rest of their life....
The purpose of this study is to evaluate the safety and tolerability of single ascending doses of ALN-HSD in healthy participants (Part A) and multiple doses of ALN-HSD in patients with NASH (Parts B and C).
This phase II trial investigates whether magnetic resonance imaging (MRI) using hyperpolarized carbon-13 (13C) pyruvate can be useful for evaluating early treatment response in patients with pancreatic cancer that has spread to nearby tissue or lymph nodes (locally advanced) or spread to other places in the body (metastatic). Hyperpolarized 13C pyruvate is different from standard clinical MRI contrast (e.g. gadolinium) in that it provides information on how a tumor processes nutrients. MRI is used to see tumor uptake and breakdown of hyperpolarized carbon-13 pyruvate molecules, which can tell how the tumor processes nutrients. Hyperpolarized 13C pyruvate MRI may help in understanding how the tumor responds to the treatments patients may be receiving.
