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.
The purpose of this study is to determine if LY2189265 is effective and safe in reducing hemoglobin A1c (HbA1c), as compared to placebo (no medicine), or exenatide in participants with Type 2 Diabetes. The participants must also be taking metformin and pioglitazone.
This study will examine the long-term effects of HIV infection, highly active antiretroviral therapy (HAART), and experimental treatments on children who participated in PACTG 219C or select IMPAACT studies.
The purpose of this study is to determine if patients with metastatic prostate cancer who have not received chemotherapy live longer when treated with ipilimumab than those treated with a placebo
Patients will be switched from their current medication for painful diabetic peripheral neuropathy to evaluate the safety and efficacy of pregabalin as compared to placebo. All patients will receive pregabalin, and half of patients will receive placebo at some point during the study.
Participants with genotype 1 HCV infection were randomized to 1 of 3 sofosbuvir doses (100 mg, 200 mg, or 400 mg) or matching placebo once daily based upon stratification for IL28B status (CC or CT/TT). Placebo tablets were administered to participants receiving 100 mg active sofosbuvir (3 placebo tablets) and 200 mg active sofosbuvir (2 placebo tablets) in order to maintain the study blind. Participants received sofosbuvir/matching placebo from Day 0 to 27. Participants also received treatment with PEG+RBV starting on Day 0 of the study which continued for 48 weeks. Participants were evaluated for sustained virologic response (SVR) for an additional 24 weeks following completion of study treatment.
The purpose of this study is to provide access to telaprevir for patients from the control group in the C216 study, who failed treatment for virologic reasons. Efficacy, safety and tolerability of telaprevir in combination with standard treatment will be evaluated.
This study is designed to evaluate safety and assess initial efficacy of VX-509, a JAK3 inhibitor, for treatment of subjects with active RA. This study will assess the clinical response of 4 doses of VX-509 compared to placebo when administered for 12 weeks to patients with active RA. The study will also evaluate the safety and tolerability of VX-509 compared to placebo when administered for 12 weeks to subjects with active RA.
The purpose of this study is to determine if the combination treatment of CTS-1027, pegylated interferon and ribavirin can improve the response rates in HCV patients who did not previously respond to pegylated interferon and ribavirin therapy.
This trial is conducted in Asia, Europe and the United States of America (USA). The aim of this trial is to compare the efficacy and safety of NN5401 (insulin degludec/insulin aspart (IDegAsp)) with insulin glargine (IGlar), both as add-on to subject's ongoing treatment with metformin + at least one OAD (oral anti-diabetic drug). The main period is registered internally at Novo Nordisk as NN5401-3590 while the extension period is registered as NN5401-3726.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of orally administered tapentadol extended release (ER) at dosages of 100 to 250 mg twice daily compared with placebo in patients with moderate to severe pain due to chronic, painful diabetic peripheral neuropathy (DPN) who tolerated tapentadol (ER) and have an initial treatment effect (pain improvement) after a 3-week, open-label titration period.
