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 aim of this study is to determine the efficacy of Fluzone High Dose vaccine and that of Fluzone® vaccine in the elderly. Primary objective: To measure the efficacy of the vaccine, defined as the prevention of laboratory-confirmed influenza caused by viral types/subtypes that are antigenically similar to those contained in the respective annual vaccine formulations. Secondary objectives: - To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, with respect to laboratory-confirmed influenza illness caused by any type or subtype of influenza virus. - To compare the clinical efficacy of Fluzone High Dose vaccine with that of Fluzone® vaccine in elderly adults, in preventing culture-confirmed influenza illness caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations.
The primary purpose of the study is to assess long-term safety and tolerability of Edivoxetine in pediatric participants with attention deficit hyperactive disorder (ADHD).
The primary goal of this study is to determine the clinical advantage of pre-treatment with mifepristone in second trimester misoprostol induction abortion. This will be a randomized controlled double-blinded trial of 20 women comparing misoprostol alone to mifepristone plus misoprostol for second trimester (14-21 weeks' LMP) medical abortion.
The purpose of this study is to evaluate the long-term safety and tolerability of Dimebon in patients with Alzheimer's disease.
This is a Phase 2b, randomized, double-blind, parallel-group, placebo-controlled, multicenter study investigating the safety, tolerability and efficacy of two oral doses of GS-9450 in adults with chronic Hepatitis C Virus (HCV). Approximately 240 subjects 18-65 years of age who meet study entry criteria will be randomized (in other words, selected at random, like flipping a coin) to one of three treatment groups (80 subjects per treatment group) as follows:GS-9450 10 mg once daily,GS-9450 40 mg once daily, or matching placebo once daily. Following randomization, subjects will return within seven business days for a Baseline (Day 1) visit, at which time study medication will be dispensed and subjects will enter a 26 week treatment phase. During the treatment phase, subjects will receive study drug once daily for 24 weeks and then taper off of study drug over the following 2 weeks by receiving study drug once every other day for one week and then every 3 days for one week. Following completion of the treatment phase, subjects will enter a 4-week off-treatment follow-up phase.
This is a study in patients with chemotherapy induced anemia receiving multi-cycle chemotherapy for the treatment of stage IV non-small cell lung cancer (NSCLC). The primary objective of the study is to demonstrate that overall survival (OS) is not worse in participants on darbepoetin alfa treated to a hemoglobin ceiling of 12.0 g/dL compared to participants treated with placebo.
The purpose of this study is to determine if apixaban is superior to placebo for preventing cardiovascular death, non-fatal myocardial infarction, or ischemic stroke in subjects with a recent acute coronary syndrome
The purpose of the protocol is to assess long-term safety and tolerability of subjects who discontinue for any reason from UK-453,061 qualifying studies.
This is a 96 week study to determine if UK- 453,061 in combination with Darunavir /ritonavir and a Nucleos(t)ide Reverse Transcriptase inhibitor is as efficacious, safe and tolerable as etravirine in combination with Darunavir /ritonavir and a Nucleos(t)ide Reverse Transcriptase inhibitor in HIV-1 infected patients who have been previously treated with antiretroviral drugs and have NNRTI resistance mutations.
The primary objective of this study is to evaluate quality of life changes in Puerto Rican subjects with Rheumatoid Arthritis treated with Humira (adalimumab) as their first Anti-TNF Monoclonal Antibody.
