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 purpose of this study is to determine whether patients treated with acupuncture post-operatively following knee or hip arthroplasty achieve better pain control as measured by the Visual Analog Scale and pain medication use.
Neoadjuvant chemotherapy has become the standard of care for breast cancer patients with large tumors in order to render them operable for mastectomy or, in some cases, for lumpectomy and radiation therapy. Building on this theme, several large hormonal therapies are extensively investigated in the neoadjuvant setting, together with biologic correlates for response and resistance. As a further extension, neoadjuvant therapies with biologic agents are now too, being investigated for biologic evidence of efficacy before large-scale clinical trials of thousands of patients are embarked on. The neoadjuvant setting is especially attractive for these studies for several reasons including early assessment of response to therapy, biopsiable access to the primary tumor, and considerable reduced sample sizes compared to those required in the adjuvant setting. In addition, clinical response to neoadjuvant chemotherapy is a validated surrogate marker for improved survival. It may be used to test the overall efficacy of neoadjuvant treatment regimens and mirrors the effect of therapy on micrometastases setting. In a recent study, good clinical response to neoadjuvant chemotherapy was the only independent variable, by multivariate analysis, associated with decreased risk of death. GW572016 is a new and promising dual tyrosine kinase inhibitor against HER1/2. Hundreds of patients were treated in phase I and II studies world-wide and results indicate that this reversible, oral small molecule is generally well-tolerated. Studies of neoadjuvant Trastuzumab indicate that HER2 interference leads to significant tumor regression even after 3 weeks of monotherapy. We aim to extend these findings with a novel agent, GW572016 that may be more effective, especially from its in vitro data, and to discover the true response rate to inhibiting HER1/2 signal transduction in breast cancer patients.
The purpose of this study is to evaluate the safety and effectiveness of iloprost for PAH in children who are between the ages of 3 and 18 years old.
Functional Hypothalamic Amenorrhea (FHA), the spontaneous cessation of the menstrual cycle for at least 6 months after menstrual cyclicity has been established, is a common and reversible form of anovulation not due to discernible organic causes. Whereas animal studies suggest an interaction of metabolic and psychosocial stress in the genesis of FHA, the distinct central mechanisms in humans are not clear. On a behavioral level, FHA appears to depend on a complex interplay between individual stress susceptibility, stressful life events, and enduring metabolic challenge due to inappropriate attitudes towards eating and body image. We will use a comparison group of ovulatory, eumenorrheic women (EW) and a contrast group of lean women with polycystic ovary syndrome (PCOS). Although women with FHA and PCOS present with anovulation, each condition differs markedly in pathobiology (and health burden). Contrasting women with FHA to those with PCOS will afford an opportunity to understand more about the interaction between metabolism, stress, and reproduction and to determine the extent to which differences between FHA and EW are attributable to reproductive compromise (anovulation) per se versus specific to the pathogenesis of FHA or PCOS. We have used this approach to great advantage in the past to show that hypercortisolemia was confined to FHA and not PCOS (Berga 1997) and that dysfunctional (unrealistic) attitudes and decreased coping skills were reported more often in FHA than in PCOS and more in PCOS than EW. Further, this approach of comparing 3 groups will allow us to improve therapeutic approaches for two principle causes of anovulatory infertility in women. To accomplish this, we will study women with FHA, PCOS, and normal ovulatory women. The study will take place over 2 months and women will make 4-5 outpatient visits to the Clinical Integration Network Center and will have one overnight stay for frequent blood sampling.
RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. Docetaxel may make tumor cells more sensitive to radiation therapy. Giving docetaxel together with radiation therapy may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of docetaxel when given together with radiation therapy and to see how well they work in treating patients with stage II, stage III, or stage IV cervical cancer.
The objective of this study is to examine the effects of pre surgery dog visits as compared to a costumed character or parents-only on the consumption of pain medication after surgery. It is hypothesized that pre surgery dog visits will reduce post surgical stress and anxiety.
The purpose of this study is to determine the effectiveness of the ViaCell's product media for freezing and thawing human eggs for future use in assisted reproductive technology.
The purpose of this study is to evaluate the change score for the PedsQL short form Diabetes and Core Modules and the Patient Assessment of Chronic Illness Care measured at baseline (before changing care delivery models) and 12 months after transitioning to the team model of care delivery.
The purpose of this study is to evaluate the safety and effectiveness of an investigational vaccine (TG4040) to prevent hepatitis C virus (HCV) infection. The primary goal of this study is to determine the safety of increasing doses of TG4040 versus placebo (an inactive substance) in subjects chronically infected with HCV. Approximately 85 patients, ages 18-65 years, with chronic HCV infection will be enrolled in this study at two sites, Saint Louis University and Cincinnati Children's Hospital. Volunteers will receive doses of TG4040 and placebo by injections into the thigh on different days, depending on which study group they belong to. Safety will be checked before doses are increased, and each participant will receive the study vaccine, TG4040, at some point during the study. Each subject will participate in the study for 8 months. This study may help produce a new vaccine that would improve control of HCV.
This study is designed to determine the rate at which stem cell transplant patients can develop infection caused by a group of viruses, known as adenovirus, and common fungi. Stem cells are unspecialized cells, capable of producing more stem cells or other specialized cells, and are used to replace damaged or diseased cells. The study will be conducted in children (2-17years old) being transplanted with stem cells from a donor. Patients undergoing stem cell transplantation are more likely to develop infections as their immune systems are weakened. Blood, stool, urine and throat swab samples will be collected (for at least 100 days on a weekly basis) to detect infection(s) caused by adenovirus or fungus. Subjects will participate for up to 1 year following the transplant procedure.
