NCT00001078
The purpose of this study is to find out if it is safe for HIV-positive children who are responding well to their anti-HIV treatment to stop taking medications that prevent AIDS-related infections (opportunistic infections) such as pneumonia and other bacterial infections. This is an observational study, meaning children will only be monitored to see if they develop any infections. Children have been receiving medications to prevent complications of HIV infection, such as Pneumocystis carinii pneumonia (PCP), Mycobacterium avium complex (MAC) disease, or other bacterial infections. It is common for HIV-positive patients with low CD4 counts to receive these preventive medications. However, these drugs can have serious side effects, they are expensive, and it is possible for bacteria resistant to the drugs to grow. For these reasons, it may be beneficial to the child to stop taking these preventive medications if he/she has been on anti-HIV (antiretroviral) therapy and has improved CD4 counts. This study will look at how many children who stop taking their medications develop opportunistic infections.
NCT00000897
The purpose of this study is to look at the effects of different methods of birth control (oral and injectable) on how the body absorbs, makes available, and removes zidovudine (ZDV). This study will also evaluate the differences in men and women in how the body absorbs, makes available, and removes ZDV. Past research has shown that the effectiveness of ZDV as an anti-HIV drug might be decreased in individuals who use certain methods of birth control. ZDV may also have different effects in men compared to women.
NCT00325195
These are two replicate studies to evaluate the safety and efficacy of PEG (polyethylene glycol)-uricase in controlling the uric acid level in symptomatic gout patients with high uric acid levels who are unable to take standard gout therapies, or for whom those therapies have been unsuccessful in controlling their uric acid level.
NCT00293332
RATIONALE: Drugs used in chemotherapy, such as docetaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving docetaxel and carboplatin together with bevacizumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying how well giving docetaxel and carboplatin together with bevacizumab works in treating patients with stage I, stage II, or stage III non-small cell lung cancer that can be removed by surgery.
NCT00241540
This study is a randomised, double-blind, parallel-group and placebo controlled study comparing the efficacy of esomeprazole 40 mg orally qd vs. placebo and esomeprazole 20 mg orally qd vs. placebo when given to patients on continuous use of NSAIDs, including COX-2 selective NSAIDs, for a period of 4 weeks in treatment of relief of upper GI symptoms.
NCT00076232
Genital herpes (HSV-2) is the most common cause of genital sores worldwide, and the presence of genital sores is a significant risk factor for becoming infected with HIV. This study will test the effectiveness of twice-daily dosing of acyclovir, a commonly prescribed anti-herpes drug, in preventing HIV infection in HSV-2 infected women who sleep with men (WSM) and men who sleep with men (MSM). Study hypothesis: Given that genital herpes is a significant risk factor to HIV acquisition, twice-daily HSV-2 suppressive therapy - 400 mg of acyclovir - will prevent HIV infection among high risk, HSV-2 seropositive WSM and MSM.
NCT00050687
This study will test the safety, tolerance, and efficacy of different doses of oral gallium maltolate. Patients will receive oral gallium maltolate twice daily for 28-consecutive days followed by 14 days off treatment. This dosing cycle will be repeated. Adverse effects will be assessed and the levels of gallium in serum will be measured. Any effect of the drug on the cancer and any improvement in cancer-related symptoms will also be measured.
NCT00190684
To learn about the safety and any side effects of atomoxetine when given to children and adolescents for about 5 years (long-term) and to learn whether atomoxetine can help children and adolescents with attention-deficit/hyperactivity disorder (ADHD) who take the drug for about 5 years (long-term). Study participants can be atomoxetine naive, atomoxetine experienced whose therapy has been interrupted or, atomoxetine experienced on a known stable dose.
NCT00797797
To evaluate the safety, tolerability, and efficacy of milnacipran when taken with another drug called pregabalin in people with fibromyalgia.
NCT00283088
The purpose of this trial is to evaluate if it is safe to use tissue plasminogen activator (tPA) within 6 hours of stroke onset when combined with hypothermia.
NCT00031434
The purpose of this study is to evaluate how ganciclovir is metabolized when administered intravenously (by a needle inserted into a vein) following valganciclovir syrup, given by mouth to newborns and young infants with symptoms of congenital (present at birth) cytomegalovirus (CMV) disease. The study also seeks to identify a dose of valganciclovir that provides a comparable blood concentration to ganciclovir present in the blood of newborns with symptomatic congenital CMV disease. All study participants will receive 6 weeks of antiviral therapy (defined as ganciclovir and/or valganciclovir). Infants from 0 to 30 days old will participate in the study for 2 years.
NCT00637533
Lumbar sympathetic blocks are part of the standard of care for treating patients with sympathetically-maintained pain (e.g. in complex regional pain syndrome or reflex sympathetic dystrophy- RSD). In these patients lower extremity pain can be reduced or abolished temporarily by blocking sympathetic nerves by doing a lumbar sympathetic block. Patients who respond only transiently to sympathetic blocks often choose between potentially dangerous lumbar sympathetic block with neurolytic agents, surgical sympathectomy, continued severe refractory debilitating pain or other risky invasive surgical procedures such as spinal cord electrical stimulation.. It is hypothesized that Botulinum Toxin Type A (BTA) injected in a lumbar sympathetic block can provide extended sympathetic blockade and thus pain relief. This pilot study aims to see if BTA can be used safely in lower extremity sympathetic blocks, and might be useful in providing prolonged pain relief.
NCT00671385
The purposes of this study is to establish normal optical values of breast tissue in the general population. This will allow for establishing normals for breast composition, and is expected to be useful in the classification of breast lesions into groups such as cysts, benign growths, inflammatory lesions, and possibly early breast cancer.
NCT00449527
The purpose of this study is to demonstrate whether subjects respond similarly to the Onset of Effect Questionnaire (OEQ) using a 1 week recall period versus a 1 day recall period.
NCT00449501
The purpose of this study is to demonstrate whether subjects respond similarly to the Onset of Effect Questionnaire (OEQ) administered pre-dose versus post-dose, while receiving SYMBICORT® pMDI 80/4.5 μg x 2 actuations twice daily or budesonide HFA pMDI 80 μg x 2 actuations twice daily.
NCT00739934
In this study we will measure the concentration of the drug called voriconazole which is used to fight infections caused by fungus in children who usually are cancer patients and have their immune system down. Since we know the dose in adults, and we think we know the matching doses in the young patients ages 2 to 12 years old, we will compare the amount of drug that goes into the system with what we know works in adults. We give the drug by a needle directly into the blood, then few days later we stop that and give the drug by mouth. Meanwhile, we draw a little bit of blood at certain times to measure the drug in it.
NCT00788944
This is a study to determine the percentage of patients with depression who are treated with extended-release venlafaxine HCl (U.S. marketed brand Effexor XR®) who are Poor Metabolizers (based on the levels of the drug in the blood) at 2D6 (a system in the liver that breaks down some medications and other chemicals).
NCT00546637
To evaluate the efficacy and safety of fesoterodine on overactive bladder symptom improvement when added to ongoing alpha blocker treatment.
NCT00812058
The purpose of this study is to test a new drug, RG2417, to see how the drug affects symptoms of bipolar I depression and to make sure it is safe in humans.
NCT00452426
Patients routinely receive sedation during a colonoscopy or upper endoscopy (esophagogastroduodenoscopy; EGD) procedure. Propofol is a sedative that can be used during these procedures. The purpose of this study is to determine if this CAPS device enables a physician/registered nurse (RN) team to safely and effectively administer propofol sedation during colonoscopy or EGD procedures relative to current sedation practices.
