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.
SSDXA-14 is a Phase 2 (feasibility/pilot) double-blind, placebo-controlled, crossover study to evaluate the efficacy and safety of sacrosidase and placebo in 25 subjects objectively diagnosed with fructan intolerance.
An Open-label, Single-ascending dose, Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of STSA-1002 Subcutaneous Injection in Healthy Subjects
The goal of this Method Comparison Study is to compare total IgE results obtained from at least 360 subjects aged less than 80 years old using four different testing arms comprising three types of samples and two testing methods. The main questions it aims to answer are: - Are the Kenota 1 Devices easy to use by untrained operators at a clinic environment? - Do tIgE results provided by the Kenota 1 Devices match the results provided by the FDA-cleared Phadia ImmunoCAP System? Subjects will be asked to donate two fingerstick whole blood samples and one venous blood draw.
The purpose of this clinical trial is to assess the clinical performance of LID223194 Multifocal (MF) contact lenses and commercially available Air Optix plus HydraGlyde (AOHG) MF contact lenses. Eligible subjects will wear each study lens type in a cross-over fashion as randomized for approximately 2 days.
The purpose of this study is to compare physiological responses in cardiovascular variables between nose and mouth breathing at rest and during exercise.
The goal of this clinical trial is to understand how the introduction of an app-based intervention changes knowledge, attitudes, and practices on COVID-19 self-testing.
The goal of this clinical trial is to learn about the vaginal microbiome in premenopausal women with recurrent bacterial vaginosis (BV). The main questions it aims to answer are: - Does using a specific vaginal care system reduce recurrence of BV? - How does using this vaginal care system change the vaginal microbiome and pH over time? Participants will: - Have their vaginal microbiome and pH tested in several ways at three timepoints: the start of the study, 12 weeks later, and 24 weeks after the start of the study - Answer questionnaires about vulvovaginal symptoms at each of these three timepoints - Use a specific vaginal care system at home for 24 weeks, consisting of an intimate wash, a vaginal moisturizing gel, and a vaginal probiotic suppository, if assigned to the intervention group Researchers will compare the group using the vaginal care system with a control group that does not use the system to see if using the system reduces risk of BV recurrence or changes the vaginal microbiome, pH, or symptoms.
Airway protection deficits (cough and swallowing) are prevalent and pervasive in Parkinson's disease (PD), contributing to adverse health outcomes like pneumonia. This study aims to refine cough skill training by examining whether variable versus constant practice conditions improve cough outcomes in people with PD. In addition, this study will provide insight into optimal respiratory adaptations that occur during training to support cough effectiveness, resulting in immediately translatable treatments to improve airway protection-related health outcomes in people with neurodegenerative disease.
Evaluation of a Novel Behavior Change Intervention for Posttraumatic Stress
This study will investigate how well OC-01 (varenicline) nasal spray can treat the signs and symptoms of dry eye disease in those Sjogren's Syndrome. Patients at least 18 years old with moderate-to-severe Sjogren's dry eye disease may be eligible for this study. If you are eligible to participate in the study and you decide to join, there will be 3 study visits over approximately 1 month. You will also self-administer the nasal spray at home every day, 2 times a day during this month.
