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.
The objective of this study is to obtain human blood CD34+ hematopoietic stem/progenitor cells (HSPCs) to reconstitute a match human immune system in our PDX model. The hypothesis is that by using matched leukocytes and PDX from the same patient, rejection of the PDX by the host immune system will not be observed and therefore a preclinical model to study immunotherapy can be developed to study, understand and improve upon our current therapies. HSPCs will be collected from bone marrow aspirate obtained from a bone marrow biopsy. The secondary objective is to use patient tumor biopsy samples or circulating tumor cell samples to develop additional preclinical models of GU cancers, particularly prostate cancer, that are clinically relevant by generating additional PDXs.
Individuals infected with HIV have a high risk of developing metabolic comorbidities not traditionally associated with the immune dysregulation and deficiency associated with HIV infection and AIDS. Many of these comorbidities in HIV uninfected individuals have been linked to a disordered circadian clock function. The study investigators will further evaluate the circadian clock in HIV infection as a mechanism underlying the metabolic dysregulation in this population.
This phase I/II trial studies the side effects and best dose of 211^astatine(At)-BC8-B10 before donor stem cell transplant in treating patients with high-risk acute myeloid leukemia, acute lymphoblastic leukemia, myelodysplastic syndrome, or mixed-phenotype acute leukemia. Radioactive substances, such as astatine-211, linked to monoclonal antibodies, such as BC8, can bind to cancer cells and give off radiation which may help kill cancer cells and have less of an effect on healthy cells before donor stem cell transplant.
Autism spectrum disorders (ASD) are highly disabling, persistent neurodevelopmental disorders. There are no available treatments for core symptoms of ASD or biologically-based clinical biomarkers. Emerging evidence indicates that levels of brain inflammation are increased in ASD. In particular, recent work implicates hyperactivity of microglial cells, the resident immune cells of the brain. However, the functional consequences of microglial activation remain unknown. This study will measure microglial activation in ASD using positron emission tomography (PET) brain imaging. Adult males with ASD (n=15) and healthy controls (n=15) will be recruited for this study and undergo comprehensive clinical and behavioral baseline assessment. All subjects will then undergo baseline PET imaging using a radiotracer that labels activated microglia. Subjects with ASD will then undergo 12-week open label treatment with minocycline, an FDA-approved antibiotic thought to block microglial activation. PET imaging will be repeated at 12 weeks to confirm target engagement. A subset of control subjects will also undergo repeat PET imaging to determine test-retest reliability. During minocycline treatment, ASD subjects will be evaluated every 2 weeks for safety, clinical impression, behavioral functioning, and measures of cognition. Results will provide important information regarding the relationship between levels of brain inflammation, cognitive and behavioral function in ASD.
Since the introduction of the combined hormonal contraceptive pill, dosages of ethinyl estradiol (EE) have steadily decreased from more than 150mcg to 20mcg in an attempt to improve the risk profile associated with the COC. In 2010, the Food and Drug Administration approved a oral contraceptive pill containing EE 10mcg/NET acetate 1mg (Tradename Lo loestrin). However, no studies have compared this formulation to pills containing either higher doses of estrogen or progestin alone. It is not known whether EE 10mcg is sufficient to prevent follicular development or to support the endometrium as well as higher doses of EE. This trial addresses the question of whether an oral contraceptive pill with EE 10mcg/Norethindrone acetate 1mg will better suppress ovulation or have a better side effect profile than a progestin only pill with a nearly equal dose of norethindrone.
Patients with migraine often report that stressors such as skipping a meal can bring on a migraine whereas some patients report that their migraine improves with food. Few studies to date have looked at the relationship between blood glucose (sugar) and migraine. We are conducting this study to better understand whether or not changes in blood glucose levels can trigger migraine or provide relief during a migraine attack.
To evaluate the safety and efficacy of Saroglitazar Magnesium 1, 2, and 4 mg in patients with fasting triglyceride ≥500 mg/dL and ≤1500 mg/dL.
In this research study the researchers want to learn more about the effects (both good and bad) the study drug selumetinib has on participants with neurofibromatosis type II (NF2) related tumor. The researchers are asking patients with NF2 related tumors to be in the study, because their hearing has decreased and/or their NF2 related tumor has started to grow. The goals of this study are: - Determine if selumetinib will stop NF2 related tumors from growing - Measure the changes in hearing after receiving selumetinib for 6 months. - Determine if selumetinib improves how participants feel (physically and emotionally) and how participants can perform daily activities. - Examine tumor tissue, if available, in a laboratory to see if NF2 related tumors have targets of selumetinib.
This research study is studying a pair of immunotherapies as a possible treatment for malignant pleural mesothelioma. The drugs involved in this study are: - Durvalumab - Tremelimumab
A prospective, single arm, multicenter study designed to demonstrate that the Sinopsys® Lacrimal Stent can safely create transcaruncular access to the ethmoid sinus to enable sinus irrigation and reduce symptoms in patients with moderate to severe chronic rhinosinusitis.
