This is a study to test if a new higher dose of Copaxone is more effective in treating relapsing-remitting multiple sclerosis than the currently available 20 mg dose.
NCT01048112
The goal of this research is to continue to develop a model of infection with Campylobacter jejuni, a bacterium that causes food and water-borne disease (mainly diarrhea). The objectives are to 1) determine if healthy subjects develop short-term (\<6 month) protection to reinfection with C. jejuni; and 2) characterize the immune responses to C. jejuni infection. Information obtained will be used in development of a vaccine against Campylobacter infections. Volunteers will be screened for eligibility within 60 days prior to enrollment. Screening will include obtaining informed consent prior to any study procedure. This will be followed by medical history, physical examination, review of current medications, blood samples for safety labs (WBC, Hct, Hgb, platelet count; chemistry panel; screening for HIV, HLA-B27, HBV, and HCV); urine pregnancy testing for females. Stool will be tested for infection. Eligible volunteers will be enrolled in the study and admitted to the GCRC on Day -1. They will drink a measured dose of C. jejuni on Day 0, and followed for approximately 9 inpatient days, during which time the investigators expect at least 75% to develop a diarrheal illness, which will be promptly treated with replacement fluids (oral or IV, as indicated) and antibiotics. During the inpatient period, subjects will be assessed for any adverse events, and blood and stool specimens will be analyzed for markers of infection and markers of immune response. Subjects must have resolved or resolving symptoms and two negative stool cultures ≥12 hours apart to be eligible for discharge, and will be seen in outpatient follow-up at 21, 28, 35, 60, and 90 days for additional AE assessments and blood and stool analysis. Eight subjects will return for redosing approximately 98 days after the initial dose, with the same inpatient and outpatient follow-up as above. Few or none should develop a diarrheal illness. Four naïve (previously unexposed) subjects will also receive the dose on Day 98 to confirm a 75% illness rate with this dose. They will be followed as the initial group was. All participants will be assessed by phone 6 months after the final dose they received.

NCT00196781
We plan to test the effectiveness of a recently developed computer-based program that is designed to improve patient knowledge about prostate cancer treatments. It is also designed to help men clarify their values using a computer-based 'decision aid.' A decision aid gives patients tools to help them understand their own values and how these values may be related to their choice of different forms of therapy for prostate cancer. In order to test the effectiveness of the decision aid, men will be assigned on a chance basis to receive either 1) the computer program that includes the information about prostate cancer treatments alone, or 2) the computer program that contains both the information and the decision aid. We expect that men in decision aid group will be more active in their treatment decision and will have improved knowledge, quality of life, and satisfaction with the treatment decision relative to men who only receive the information.

Patients who require chronic anticoagulation with one or more of the following conditions are eligible for the study: atrial fibrillation or atrial flutter, prosthetic heart valve, venous thromboembolic disease, or history of myocardial infarction or cardiomyopathy will be enrolled.
NCT00702819
Retinopathy of Prematurity (ROP) is a leading cause of blindness in children in developed countries around the world, and an increasing cause of blindness in developing countries. The retina lines the inside of the eye. It functions as "film" within the camera which is the eye. When an infant is born prematurely, the vascular network necessary to nourish the retina has not fully developed. As a consequence, in some infants abnormal vessels proliferate instead of the normal ones - a condition known as ROP. The abnormal vessels carry scar tissue along with them, and may lead to retinal detachment and blindness if the eye is not treated. The Multicenter Trial of Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) Study demonstrated that ablation of the peripheral avascular retina reduced the risk of poor structural and visual outcome due to retinal distortion or detachment in ROP (1980's). The ablated retina is not functional and is not amenable to regeneration. Peripheral retinal ablation is not universally effective in fostering regression of ROP. This is particularly true for an aggressive form of ROP (aggressive posterior ROP, or APROP) which typically afflicts profoundly premature and infirm neonates. In this subset of infants, progression of ROP to bilateral retinal detachment and blindness occurs despite timely and complete peripheral retinal laser ablation. Rationale The development of ROP is largely dependent on vascular endothelial growth factor (VEGF). When an infant is born prematurely the relatively hyperoxic environment the baby is introduced to shuts down the production of VEGF. Retinal maturation is delayed. Subsequently, at a time when intraocular VEGF levels would normally be declining late in the third trimester of pregnancy, abnormally high levels of VEGF are seen due to large areas of avascular retina and associated tissue hypoxia. The availability of FDA-approved drugs for anti-VEGF treatment renders it possible to treat such eyes off-label. Available drugs include pegaptanib sodium (Macugen) for partial blockage of VEGF-A, or drugs such as ranibizumab (Lucentis) and bevacizumab (Avastin), which cause complete blockage of VEGF-A. As VEGF is required in the developing retina for normal angiogenesis, and our goal is not to penetrate tissue, but to block the excessive levels of VEGF trapped within the overlying vitreous which is responsible for the abnormal vasculature in ROP. For purposes of this study the investigators have chosen bevacizumab (Avastin), which will: a) attain complete blockage (vs. Macugen) of intravitreal VEGF-A, and; b) which is limited in its ability to penetrate tissues because it is a full antibody (vs. Lucentis, an antibody fragment specifically designed for better tissue penetration), and is more likely to restore VEGF homeostasis within the developing retina.

NCT00061737
Measurement of the quality of life (QoL) of children and adolescents with inflammatory bowel diseases (IBD) has had little attention, despite the importance of understanding key factors affecting QoL, especially for measuring the effects of clinical trials to improve IBD outcomes. The main purpose of this pilot study is to examine the impact of clinical severity and treatment social factors on the quality of life (QoL) of a diverse population of children and adolescents with inflammatory bowel disease (IBD). Secondary purposes include determining the effects of sociodemographic factors on QoL and exploring the concordance of views of parents and children of QoL. The study aims are to 1) determine the associations of of clinical characteristics (condition type, activity/severity, and treatment) with specific components of general health-related quality of life and IBD-specific QoL; 2) describe the effects of sociodemographic characteristics (SES, age, and gender) on these measures; and 3) compare the views of different observers (parent and child with IBD) of the child's QoL. The study will apply both general and condition-specific QoL measures among a random sample of 250 children and adolescents with IBD, ages 5-18 years, in six clinical sites. We will obtain measures of QoL from both the child and a parent in each case. The study will obtain additional data regarding the subjects' clinical condition (condition type, severity/activity, treatment \[including surgery\], age of onset) and socioeconomic status (household structure and income). Main analyses will compare general and specific measures of QoL and examine the influence of clinical and sociodemographic variables on QoL, through multivariate regression techniques. We will also examine the differences in child and parent assessments of QoL. The information from this study will provide a stronger base for future studies of treatment and natural history of IBD. It will help to clarify the life domains that are affected by IBD and will inform interventions to improve QoL for children with IBD.
NCT00516100
Pemetrexed is an FDA-approved treatment for advanced lung cancer but the response rate is still very low. Bortezomib is currently approved to treat myeloma in patients who have already been treated. Currently, multiple studies are actively investigating how well bortezomib works with other drugs. This study is testing how much bortezomib can be given to advanced lung cancer patients who have already received one treatment. This study will also see how well bortezomib and pemetrexed work together to treat lung cancer patients.
