The purpose of this research study is to determine the effectiveness of 2 target doses of R228060 in comparison with placebo during 6 weeks of treatment in moderately to severely depressed adult subjects with major depressive disorder. Approximately 488 subjects will be involved in the study.
To prevent HIV infection, a vaccine that produces strong HIV-specific humoral (B-cell) and cellular (T-cell) immune system responses is desirable. The purpose of this study is to test the safety of and immune response to a novel combination HIV vaccine in HIV uninfected adults. This study will also test the safety of and immune response to a protein vaccine given alone.
This trial is for patients with a central venous catheter (a vascular access device) that is not functioning properly (unable to withdraw blood). The trial compares a new blood clot dissolving agent (alfimeprase) against the currently used treatment.
Primary Objective: To compare the antidepressant efficacy and safety of subjects receiving DVS-233 SR versus subjects receiving placebo. Secondary Objective: To assess the response of subjects receiving DVS-233 SR for the clinical global evaluation, functionality, general wellbeing, pain, and absence of symptoms (Hamilton Psychiatric Rating Scale for Depression, 17-item [HAM-D17] less than or equal to 7) versus those subjects receiving placebo.
Microbicides are drugs that destroy microbes such as viruses and bacteria. Rectal microbicides may be able to prevent transmission of HIV during anal intercourse. The purpose of this study is to obtain rectal samples from men to learn information that may be valuable in future clinical trials of rectal microbicides.
Primary Objective: To compare the efficacy and safety of DVS-233 SR versus placebo treatment in reducing the relapse rate of depressive symptoms in subjects with major depressive disorder (MDD), and to compare the percentages of relapse in terms of time to relapse between DVS-233 SR and placebo treatment groups by using survival analysis. Secondary Objective: To assess the response of subjects on DVS-233 SR versus placebo for the clinical global evaluation, functionality, general well-being, pain, and absence of symptoms (Hamilton Psychiatric Rating Scale for Depression, 17-item [HAM-D17] < 7).
The purpose of this study is to determine the effectiveness of fish oil supplements combined with the drug fenofibrate in treating elevated triglyceride levels in people taking anti-HIV drugs. The participants in this study will have shown no response to fish oil supplements or fenofibrate alone.
The primary purpose of this study is to evaluate the safety, toxicities, and dosage for investigational drug Motexafin Gadolinium administered with docetaxel to patients with advanced solid tumors. Secondly, tumor response to the combined treatment will be evaluated.
The purpose of this study is to find out about the safety of adding the investigational drug motexafin gadolinium to a standard course of chemotherapy with temozolomide for patients with malignant glioma. Secondly, the study will determine how many patients will respond to this treatment.
The purpose of this study is to determine the antitumor activity (response rate, time to tumor progression, survival) and safety of docetaxel in combination with talabostat in patients with advanced non-small cell lung cancer (NSCLC) who have failed a prior platinum-containing regimen.
