NCT00552240
The aim of this clinical trial is to compare the efficacy and safety of ritonavir (RTV)-boosted atazanavir with nevirapine, each on a background of emtricitabine and tenofovir disoproxil fumarate (DF).
NCT00002791
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy with more than one chemotherapy drug may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy followed by surgery in treating patients who have soft tissue sarcoma.
NCT01962805
This study is a double-blind crossover study in female healthy volunteers to compare the pharmacokinetics and safety of either 1 or 6 days of dosing with two different formulations of Proellex for vaginal administration. Each formulation will be designated as either Treatment A or Treatment B. A total of 8 subjects who meet the eligibility criteria will be randomized to receive either Treatment A or Treatment B as their first assigned treatment. Subjects will receive a single dose of Treatment A or daily dosing with Treatment B for 6 days. After a 7-day washout period subjects will receive the alternative treatment. On the day of treatment with Treatment A and on the first and last days of treatment with Treatment B subjects will remain in the clinic overnight and undergo 32-hour pharmacokinetic assessment at the following time points: 0, 0.5, 1, 2, 4, 8, 12, 16, 20, 24, 28 and 32 hours after administration of study drug. For Treatment B study drug will be administered in the clinic each day after a trough blood sample has been drawn.
NCT01570686
The purpose of this study is to evaluate the effect of food on aliskiren's efficacy, pharmacokinetics and safety following an oral dose of 300 mg, given once daily under light meal versus fasted conditions.
NCT00997178
The primary aim of the study is to determine if non-surgical periodontal therapy (scaling and root planing and supportive periodontal therapy) is efficacious compared to delayed therapy in reducing elevated glycosylated hemoglobin (HbA1c) at 6 months post-randomization in subjects with type 2 diabetes and untreated, moderate to advanced chronic periodontitis. The secondary aims of the study are to: 1. evaluate whether 6 month (or shorter-term (3 month)) changes in clinical measures of chronic periodontitis (gingival index, bleeding on probing, probing depth, clinical attachment level) are related to changes in HbA1c and fasting glucose or insulin resistance as measured by the Homeostasis Model Assessment 2 (HOMA2). 2. assess the 3 month and 6 month efficacy of periodontal therapy on all of the above study outcomes. If a treatment response is observed for any of the study outcomes at 3 months, then the trial can evaluate whether this response is sustained at 6 months.
NCT00131248
Study Question: In premature infants with apnea and/or bradycardia attributed to gastroesophageal reflux disease (GERD), does treatment with medications (acid blockers and motility agents), compared to placebo, reduce the frequency of apnea and bradycardia? Background: Many clinicians believe that apnea and bradycardia in preterm infants may be caused by gastroesophageal reflux (GER), however, studies have failed to demonstrate even a temporal association between episodes of GER and apnea. There have been no prospective randomized trials of treatment for GERD in preterm infants with apnea or other symptoms attributed to GER. Methods: A randomized, cross-over study will be performed. This cross-over design will provide the patient's clinician with unbiased information about the patient's response to treatment. The clinician can use this information in deciding whether or not to continue treatment after the two-week study period.
NCT01717989
To describe trends in treatment patterns of Small Dialysis Organizations (SDOs) prior to and during the implementation of the Centers for Medicare and Medicaid Services' (CMS') policy \[End Stage Renal Disease (ESRD) Prospective Payment System (PPS)\] to bundle reimbursement for all dialysis services. Specifically, to describe CMS ESRD PPS quality performance measures for dialysis centers over time.
NCT00162227
This study is being conducted to assess the safety and tolerability of an oral liquid solution of Sustiva for antiretroviral therapy-naive or therapy-experienced HIV-1 infected children between the ages 3-16 who are failing or intolerant of current antiretroviral regimen and who are unable to swallow Sustiva capsules.
NCT00003917
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if topotecan is more effective given by infusion or by mouth. PURPOSE: Randomized phase III trial to compare the effectiveness of topotecan given by infusion with that of topotecan given by mouth in treating patients who have small cell lung cancer that has relapsed following previous therapy.
NCT01586533
This double-blind, randomized, comparator-controlled Phase II study is designed to establish the safety and efficacy of Zoenasa Rectal Gel compared to mesalamine enema in subjects with left-sided ulcerative colitis, as measured by the modified ulcerative colitis disease activity index (UCDAI), over 6 weeks of treatment. In this study, two cohorts of subjects will receive either Zoenasa-1:4 (1.0g NAC; 4.0g 5-ASA) investigational drug enema therapy or comparator mesalamine enema (4.0g 5-ASA). The study will enroll subjects randomized equally into the 2 cohorts. Each cohort will enroll approximately 60 subjects. The two arms of the trial will be enrolled concurrently in a randomized fashion.
NCT00971048
To compare HP828-101 to standard of care for the management of partial or full thickness wounds
NCT00667446
The purpose of this extension study is to determine if leuprolide acetate (11.25 mg and 30 mg) is safe in treating children with Central Precocious Puberty over a longer period of time (36 months).
NCT00074386
With improved anti-HIV drug therapy, HIV infected patients are now living longer. These patients are at risk for liver and kidney failure and may need organ transplants. However, little is know about the safety and effectiveness of organ transplants in patients with HIV. This study will evaluate organ transplantation in HIV infected patients undergoing liver and kidney transplants.
NCT01048255
The purpose of this study is to determine the safety, tolerability, and efficacy of VX-765 in subjects with Treatment-resistant Partial Epilepsy
NCT01134393
The general aim of this trial to determine the efficacy as measured by the percentage of patients reaching blood pressure goal at the end of the treatment period at 12 weeks. In-clinic blood pressures, home blood pressures and safety will be carefully monitored.
NCT00002670
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether radiation therapy plus cisplatin is more effective than radiation therapy alone in treating patients with head and neck cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy plus cisplatin with radiation therapy alone in treating patients with head and neck cancer that has been removed during surgery.
NCT00862459
The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Gadavist when used for taking images of the brain and spine. The results of the MRI with Gadavist Injection will be compared to the results of MR images taken without contrast and with the results of the MR images taken with OptiMARK.
NCT00282581
The purpose of this study is to assess the safety and immunogenicity of two MVA smallpox vaccine injections in healthy adults that are 18-35 years of age with HIV infection
NCT01306630
This is an open-label, multi-center, dose-finding study of tivozanib administered in combination with capecitabine. During the dose-escalation portion, sequential cohorts of subjects with advanced solid tumors will be enrolled in order to establish the maximum tolerated dose (MTD). If the MTD is not reached, the recommended Phase 2 dose (RP2D) will be determined. In the expansion cohort, subjects with locally advanced or metastatic breast or colon cancer will be enrolled at MTD (or RP2D) to further evaluate safety and activity of this combination in these tumor types.
NCT00933036
