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 aims to increase uptake of the COVID booster vaccine through messaging informed by Construal Level Theory. Patients in the Mass General Brigham (MGB) health system aged 18 and older who are eligible for the COVID booster vaccine, but who have not yet received a dose at the time of an upcoming primary care clinic visit, will be randomized to one of three messaging arms: 1) "why" messaging, 2) "how" messaging, or 3) standard of care ("usual care"). Messages will be sent via the electronic patient portal a few days in advance of their office visit. The primary outcome will be the rate of booster vaccination at the targeted visit. The secondary outcome will be the rate of receipt of a COVID booster vaccine within 6 weeks of the targeted visit. Subgroup analyses to assess for any association of patient characteristics with intervention responsiveness will be exploratory.
A Non-Randomized, Open-Label, Drug-Drug Interaction Study to Evaluate the Effects of Fluconazole on the Pharmacokinetics and Safety of EDP-938 in Healthy Subjects
Subjects are users on Amazon's Mechanical Turk (MTurk) platform. MTurk users will be asked to complete a screening survey about family structure. The purpose of the screening survey is to identify MTurk users who are biological mothers of children aged 1.5 to 6 years old, and to collect survey information on how mothers interact with their children, with the aim of better understanding family relationships.
Single blinding study comparing FDA cleared device for prevention of medically diagnosed migraine pain to placebo.
This study will evaluate the clinical efficacy and safety of the BTL-899 device for toning of buttocks. The study is a prospective multi-center open-label two-arm study. The subjects will be enrolled and assigned into two study groups. The subjects will be enrolled and assigned into two study groups; HIFEM+RF (HR) and HIFEM (H) group. Subjects of both groups will be required to complete four (4) treatment visits and two follow-up visits.
This Open-label Extension trial will evaluate the safety and efficacy of ABP-450 for the treatment of cervical dystonia in adults. The study will enroll 60 patients across approximately 42 sites in the United States from Phase 2 (ABP-19000) and Phase 3 (ABP-19001) trials and 29 sites in Europe from Phase 3 (ABP-19001) trial. Study subjects who had their initial dose of study drug in Phase 2 or Phase 3 trial studies, irrespective of treatment allocation, will be eligible to enroll in this OLE study.
Ketamine is commonly used for procedural sedation and analgesia. It is widely used for trauma cases in the emergency department and is considered a superior agent in the outpatient setting due to its lack of respiratory and cardiovascular depression. In chronic opioid users, ketamine decreases acute pain and reduces postoperative opioid consumption. Few studies have examined the use of ketamine for surgical abortions. Previous studies found significant rates of emergence phenomena; however, this can be prevented if a benzodiazepine is given at the same time. Ketamine deserves further study to determine whether it is an acceptable alternative to a standard opioid-based regimen for surgical abortion. Our primary objective is to compare patient satisfaction after surgical abortion among patients receiving IV ketamine versus IV fentanyl for procedural sedation. Our secondary objectives include postoperative pain, additional pain medication used, and postoperative opioid use after the procedure. Our hypothesis is that ketamine will provide similar patient satisfaction and reduce postoperative opioid use. This will be a randomized controlled noninferiority clinical trial of 84 women receiving either IV ketamine with IV midazolam or IV fentanyl with IV midazolam for outpatient one day surgical abortions up to 13, 6/7 weeks gestation. Both groups will receive a standardized paracervical block and additional pain medication as needed. Our study has the potential to introduce IV ketamine as a satisfactory medication for outpatient surgical abortions. Ketamine may decrease the need for IV fentanyl, reduce postoperative opioid use, and may prove to be a superior analgesic for chronic opioid users.
The purpose of this study is to evaluate the effect of the Noom Healthy Weight Program, a digital behavior change weight loss intervention, on quality of life as measured both by self-report and objective measures, compared to a waitlist control condition.
This study is to evaluate antiviral activity, efficacy, safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of GSK3810109A in HIV-1 infected treatment naive adults. Participants will receive a single dose of GSK3810109A administered either intravenously (IV) or subcutaneously (SC). The study includes a screening phase, a randomized monotherapy phase and a standard of care follow-up phase.
This phase I trial studies the side effects of image-guided hyper-fractioned proton therapy in treating patients with head and neck cancer that has spread to nearby tissue or lymph nodes (locally advanced) and cannot be removed by surgery (unresectable). Radiation therapy uses high energy protons to kill tumor cells and shrink tumors. The change in dose radiation frequency and dose investigated in this study may help to better control the tumor and prevent it from coming back or growing. The goal of this study is to test a new radiation schedule that administers more radiation to the tumor tissue using image guided proton therapy for patients that have a high risk of having a tumor recurrence (the tumor comes back after treatment).
