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.
Phase 1 study to assess the safety, preliminary efficacy of CD19 t-haNK and to determine the maximal tolerated dose and designate the recommended phase 2 dose in subjects with diffuse large B-cell lymphoma (DLBCL).
This is a safety study of the molecule VU319 to ascertain pharmacokinetic and pharmacodynamic data and test cognitive enhancement in healthy volunteers.
The primary aim of this study is to determine the presence of gemcitabine in childhood diffuse midline gliomas (DMG) (previously classified as diffuse intrinsic pontine glioma [DIPG]) after systemic treatment with the drug.
It is well known that patients with spinal muscular atrophy (SMA) have progressive decline of respiratory muscle function. Therapy traditionally involved supportive means to ensure optimal nutrition and airway clearance. Nusinersen (spinraza) is a disease-modifying medication approved for treatment of SMA in pediatric and adult patients. The goal of this study is to observe pulmonary function test (PFT) changes and respiratory muscle strength trends throughout the first year of treatment. A prospective, longitudinal study measuring pulmonary function testing (PFTs) changes in spinal muscular atrophy (SMA) patients. Patients will be patients with SMA who are approved and maintained on nusinersen. Patient will have a baseline PFT. Investigators will repeat PFT at 3, 6, and 12 months while on nusinersen treatment.
The purpose of this study is to determine whether using hyperbaric oxygen (HBO) improves wound healing for patients who have a crush injury. The comparison of the prospective intervention group to the retrospective matched cohort aims to show that HBO can improve wound healing and decrease poor outcomes for patients with crush injuries. The information gained from this small study will serve as a basis for a follow-up prospective, randomized control trial to further delineate the role of HBO in a larger patient population.
The purpose of this study is to evaluate the efficacy of later school start times in increasing student sleep, and examine the association between later start times and physical activity, screen time, and commute time. Subjects will wear a FitBit activity tracker wristband for two separate 3-month periods (the year before and the year after the Francis Parker High School start time change in the Fall of 2020) and be advised to wear it as much as possible, especially while sleeping or performing physical activity. At the beginning and end of each study period (at 4 occasions), subjects will fill out a few short, non-invasive surveys about their commute, after-school activities, sleepiness, and preferences for morning or evening, and perform the non-invasive psychomotor vigilance test to measure alertness.
This study will examine the effects of electronic cigarette e-liquid nicotine content in a randomized, crossover clinical and behavioral pharmacology study of experienced adult e-cigarette users (N=36). The specific aim is to determine the impact of nicotine content of e-liquid on nicotine pharmacology, systemic exposure to toxic volatile organic compounds, and short-term cardiovascular effects.
Pelvic pain syndromes have a high prevalence of up to 8% in the general population and up to 50% following pelvic trauma and pelvic surgery. While medical management is the initial therapeutic step, it is often ineffective with surgical decompression and resection of the putative nerves being the ultima ratio. Cryoablation can induce long-lasting nerve conduction blocks with resultant pain relief for several months. The objective of this study is to evaluate the effectiveness of magnetic resonance (MR) neurography-guided cryoanalgesia for the treatment of pelvic and associated pain syndromes.
The purpose of this study is to evaluate the safety and immunotherapeutic activity of cemiplimab in participants with hepatitis B virus (HBV) on suppressive antiviral therapy.
Background: Researchers have found a new way to treat cancer. The therapy used in this study is called E7 TCR T cell therapy. This therapy is a type of treatment in which a participant s T cells (a type of immune system white blood cell) are changed in the laboratory to attack cancer cells. This treatment might help people with human papilloma virus (HPV)-associated oropharyngeal cancer. Oropharyngeal cancer is a type of head and neck cancer that happens in the oropharynx (the part of the throat at the back of the mouth, including the soft palate, the base of the tongue and the tonsils). Certain types of the HPV virus can cause this kind of cancer and this study is looking at those cause by HPV-16. Objective: The purpose of this study is to find out if injecting E7 TCR T cells directly into cancer tumor(s) can be done without delaying standard treatment for stage I oropharyngeal cancer, which may include surgery or radiation therapy with chemotherapy. Eligibility: People aged 18 and older with borderline resectable or unresectable Stage I, HPV-16 associated oropharyngeal cancer. Design: Participants will be screened with HLA typing (a blood test needed for eligibility) and HPV testing of the cancer tumor (to determine if the cancer is HPV-16 positive). A new biopsy may be needed if tumor from an outside location is not available for HPV testing. Eligible participants will come to the NIH campus to have a screening evaluation which will include physical exam, review of medical history and current medications, blood and heart tests, imaging (X-ray, CT scan, MRI or PET scan), and evaluation of participant s veins that are used for drawing blood. If the participant is eligible for the study based on the screening evaluation, they will have a baseline evaluation prior to receiving the experimental treatment which may include additional laboratory or imaging tests. A biopsy of the primary tumor may be performed before getting the cell injection and approximately 4 weeks after the cell injection. Participants will have a large IV catheter inserted into a vein to undergo a procedure called leukapheresis. Leukapheresis is the removal of the blood by a machine to collect specific white blood cells. The remaining blood is returned to the body. This procedure is needed to collect the cells that will be modified to target the cancer. The cells are grown in the lab and given back to the participant through an injection into the participant's tumor. It takes 11-15 days to grow the cells. Once the cells are ready, participants will receive an injection of E7 TCR T cells directly into the primary tumor and any lymph nodes that can be seen or felt on physical exam. The injection will be done in the clinic or the operating room and may require general anesthesia. Participants will recover in the hospital until they are well enough to go home, which will be about 1-2 days after the cell injection. Participants will have follow-up visits starting 2 weeks after cell injection. These will be visits to monitor the safety of the treatment and to evaluate the response of the cancer to the treatment. If the cancer appears to be growing at the 2-week visit, participants will go back to their local doctor for further care. If the cancer is not growing, participants will return for another follow-up visit 4 weeks after cell injection to see how the cancer is responding. Regardless of whether the cancer is shrinking or not, all participants will be referred to their home physician for further care after the 4-week visit. After receiving cell therapy, participants will be followed on a long-term gene therapy protocol. Participants will have blood drawn periodically to test if the cells have grown or changed. These blood tests will take place immediately before the cells, and then at 3, 6, 12 months for the first year and then annually. These tests can be drawn locally and sent to the NIH. Participants will be asked to return to the NIH annually for a physical examination for 5 years after they receive the cell injection. If participants are not able, to return to the NIH annually, they may be contacted at home and asked to have records sent from their local doctor. After that time, participants will be asked to fill -out a questionnaire for the next ten years, for a total follow-up period of 15 years.
