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.
Irritable bowel syndrome (IBS) is a very common functional gastrointestinal disorder affecting nearly 20% of the North American population. IBS is characterized by chronic abdominal, associated with a change in bowel frequency and or consistency that lack a known structural or anatomic explanation. Current treatment for IBS is primarily symptom-based. However over a third of patients with IBS fail to respond to currently available therapies. The prevalence of vitamin D deficiency/insufficiency is estimated in over a billion people world-wide . Vitamin D has potential mechanisms not only in the balance of calcium and bone homeostasis, but also a key modulator of the immune system. Vitamin D receptors (VDRs) are located on all nucleated cells including the GI tract. Thus far, there is already accumulating evidence for a role for vitamin D supplementation in inflammatory bowel disease (IBD). A recent systematic review suggested there may be benefits of vitamin D supplementation in IBD. Vitamin D insufficiency is widespread in patients with IBS and there is a positive association between vitamin D status and quality of life. To date, there is no US trial examining the effect of vitamin d supplementation on IBS symptoms and quality of life in patients with IBS.
A Phase 1B study of the efficacy of a topically-administered 7-amino acid peptide labeled with a near-infrared fluorophore Cy5 for detecting neoplastic areas of the colon is proposed. The study will test the efficacy of administering this agent (QRH-882260 Heptapeptide) to human subjects undergoing clinically-indicated colonoscopy for endoscopic resection of known colonic adenomas or for surveillance biopsies of known dysplasia in the setting of irritable bowel disease (IBD). Up to 120 evaluable subjects will be enrolled. Subjects will be recruited around scheduled standard of care procedures. The endoscopists performing the procedures are all endoscopists credentialed at the University of Michigan to do these procedures. Urine for dipstick pregnancy testing (if applicable) will be collected before the procedure, along with medical information. Vital signs are routinely monitored throughout the clinical procedure and are available in the electronic medical record. The endoscopy will proceed per the University of Michigan Health System (UMHS) standard of care. The endoscopist performing the clinical procedure will evaluate the potential risk (if any) for the subject to continue with the procedure or study. Five mL of the reconstituted QRH-882260 Heptapeptide (~100 μM) will be sprayed onto the site of interest through a catheter in the endoscope. Five minutes after QRH-882260 Heptapeptide application, the unbound peptide will be washed off using the endogator irrigator and the residual liquid will be suctioned. Pictures with white-light and fluorescence will be taken with the scanning fiber based molecular imaging endoscopic probe inserted via the instrument channel of the standard endoscope before the QRH-882260 Heptapeptide application, immediately after application and then again after the QRH-882260 Heptapeptide will be washed off. The area of interest identified will be resected/biopsied per discretion of the endoscopist per clinical care. All specimens taken are for clinical care only (not research use) and will be sent for routine histology per UMHS standard of care.
The CHOICE Registry will describe real-world treatment patterns and physician and patient (and caregiver)-reported outcomes associated with patients who have progressed beyond 2nd line metastatic colorectal cancer.
This study proposes to evaluate the accuracy of contrast-enhanced ultrasound (CEUS) in diagnosing abdominal solid organ injuries in pediatric patients. 146 subjects will be enrolled across approximately 8 sites in the US. All subjects will have had a Computerized Tomography (CT) scan as part of standard of care, confirming at least one solid organ abdominal injury. All subjects will have an abdominal ultrasound without contrast, followed by a contrast-enhanced ultrasound using the contrast agent Lumason. Ultrasound and contrast-enhanced ultrasound results will be compared to the CT scan results. The study procedures will take place within 48 hours of injury.
This trial studies the side effects of recombinant EphB4-HSA fusion protein when given together with azacitidine or decitabine in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia that has come back or has not responded to previous treatment with a hypomethylating agent. Recombinant EphB4-HSA fusion protein may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hypomethylating agents, such as azacitidine and decitabine, slow down genes that promote cell growth and can kill cells that are dividing rapidly. Giving recombinant EphB4-HSA fusion protein together with azacitidine or decitabine may work better in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia.
This study is designed to compare outcome data for patients who have recently undergone surgery with the iTotal® Posterior Stabilizing (PS) Knee Replacement System (hereafter referred to as the "iTotal") versus those who have undergone surgery with Off-the-Shelf (OTS) systems.
This study was designed to evaluate the effect of two dose levels of NUC-1031 (500 mg/m2 and 750mg/m2) in patients with ovarian cancer. The primary objective was to determine the anti-tumor activity of NUC-1031 at the selected dose level (500 mg/m2 or 750 mg/m2).
The main purpose of this clinical study is to see if a maintenance dose of GEN-003 reduces the number of days that subjects have a genital herpes recurrence. The second purpose of the study is to evaluate the safety and tolerability of a maintenance dose of GEN-003.
The overall goal of this project is to investigate the diagnostic performance of integrated F-18 fluorodeoxyglucose-positron emission tomography (FDG-PET) and Dual Energy CT (DECT) imaging in determining the thoracic nodal status of small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC), and its impact on target volume delineation for image guided radiation therapy (IGRT) planning.
This is a study to assess the pharmacokinetics, safety and tolerability of multiple ascending oral doses of ABBV-553 in healthy volunteers and the pharmacokinetics, safety, tolerability and efficacy of multiple ascending oral doses of ABBV-553 in participants with psoriasis under non-fasting conditions.
