There are about 2656 clinical studies being (or have been) conducted in Puerto Rico. 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.
SB497115 is an oral agent which activates the thrombopoietin receptor and increases platelet counts in healthy volunteers. This study is examining several different doses of SB497115 as a treatment for patients with chronic hepatitis C-related thrombocytopenia who are potential candidates for antiviral treatment with pegylated interferon and ribavirin. The study will be conducted in two phases, Parts 1 and 2. In Part 1, study subjects will be randomized to 4 weeks of SB-497115-GR or placebo administered daily without antiviral therapy. Subjects who successfully complete Part 1 (platelet count 70,000/µL for Pegasys and platelet count 100,000/µL for PEG-Intron) will then proceed to Part 2. In Part 2, subjects will receive an additional 8 weeks of SB-497115-GR or placebo administered daily with antiviral therapy.
The purpose of this study is to compare Lispro Mixture Therapy (insulin lispro 50/50 given three times daily with meals) to Glargine Basal-Bolus Therapy (insulin glargine daily with the addition of insulin lispro given three times daily with meals). The study is also comparing two different methods for adjusting the dose of insulin.
The purpose of this study is to evaluate the dose-response relationship of antiviral activity after 48 weeks treatment with 3 different dose regimens of TMC278.
QVAR in a standard press and breath inhaler (QVAR-MDI) has been approved by the Food and Drug Administration (FDA) for use in the United States. The purpose of this study is to determine the level of asthma control when comparing the safety and effectiveness of QVAR in two different devices, a metered dose inhaler (MDI) and a breath operated inhaler (BOI).
The purpose of this study is to determine the effect of the anti-HIV drug tenofovir disoproxil fumarate (TDF) on lipid levels in HIV infected adults on stable anti-HIV drug therapy. Study hypothesis: The addition of TDF to stable background antiretroviral therapy in HIV infected individuals with dyslipidemia will result in a reduction of non-HDL after 12 weeks of treatment.
This single arm study will evaluate the efficacy and safety of PEGASYS (180 micrograms sc weekly) plus ribavirin (1000-1200mg po daily) in treatment-naive Latino patients versus non-Latino Caucasian patients with chronic hepatitis C- genotype 1. The anticipated time on study treatment is 3-12 months and the target sample size is 500+ patients.
The purpose of this study is to determine the safety of two recombinant HIV vaccines in HIV infected young adults on stable anti-HIV therapy.
This study will evaluate 2 licensed vaccine products (Recombivax and Twinrix) given in a two-dose schedule to youth at risk for hepatitis B and HIV infection to evaluate immunogenicity of the products in this population, barriers to vaccine delivery, and factors which predict a diminished immune response. Since these youths are also potential candidates for future HIV vaccine trials, this study will also include preliminary assessment of youths' understanding of informed consent forms, and willingness to participate in a vaccine trial and return for multiple visits (including blood draws for immunologic assessment).
A number of factors influence HIV-positive adolescents' acceptance of and willingness to continue taking anti-HIV medicines. These factors include mental health and substance abuse issues, barriers such as lack of medical insurance, and cognitive-behavioral barriers (such as a person's impression of the impact of the medicines on his/her health and a person's sense of his/her ability to continue taking the medications prescribed). The purpose of this study is to use a survey to determine how common specific barriers are that prevent HIV positive adolescents from taking their anti-HIV medicines and if those barriers cluster together. The information collected will be used to develop and validate a schema for classifying HIV medication adherence by barriers to adherence or clusters of barriers to adherence. This classification schema could then be used in the development of interventions that better meet the needs of HIV-infected youth.
This 3 arm study will compare the safety and efficacy, with respect to a reduction in signs and symptoms and prevention of joint damage, of tocilizumab versus placebo, both in combination with methotrexate (MTX) in patients with moderate to severe active rheumatoid arthritis. Patients will be randomized to receive tocilizumab 4 mg/kg IV, tocilizumab 8 mg/kg IV or placebo IV, every 4 weeks. All patients will also receive methotrexate, 10-25 mg/week. The anticipated time on study treatment is 1-2 years and the target sample size is 500+ individuals. After completion of the 2 year study participants could participate in the optional 3 year open label extension phase (year 3 to 5).
