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.
This study investigates if Celebrex is as effective as tramadol hydrochloride (Ultram) for patients with chronic low back pain, when administered over a 6-week period.
The purpose of this study is to test specific device programming in patients without a previous history of a life-threatening, abnormally fast heartbeat who are implanted with a Medtronic ICD (Implantable Cardioconverter Defibrillator) or ICD with CRT (Cardiac Resynchronozation Therapy) device. The information learned from this study could be used to guide physicians in future ICD or CRT device programming.
This study will compare insulin lispro low mixture [LM] and insulin glargine both in combination with the patient's oral diabetes medicines, for their ability to control blood sugar in patients with type 2 diabetes and compare insulin lispro LM to insulin glargine with regard to the length of time that the overall blood sugar can be controlled. This study will also determine whether the safety of insulin lispro LM and any side effects that might be associated with it are different from those observed with insulin glargine, both in combination with the patient's oral diabetes medications. The addendum study (Intensification Addendum) will compare how different insulin treatments work to control blood sugar in patients whose diabetes could not be controlled by either insulin lispro LM or insulin glargine.
The purpose of this study is to determine safety & efficacy of SEROQUEL SR™ in the treatment of major depressive disorder compared to placebo & to evaluate quality of sleep, overall quality of life, and effect, if any, on anxiety and satisfaction PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation.

The purpose of this study is to evaluate the safety, tolerability and antiviral effects of atazanavir (ATV) plus ritonavir (RTV) versus a combination drug of lopinavir (LPV) plus RTV. A combination drug containing tenofovir (TDF) and emtricitabine (FTC) will also be taken by participants in both arms.
During Phase III, Adolescent Trials Network for HIV/AIDS Interventions (ATN)/Connect-to-Protect (C2P) site staff, their official community partners established in Phase I, and newly invited community sector representatives (i.e., individuals from various key parts of the community such as family, spiritual or faith-based institutions, business and government) will form a coalition that will work toward achieving C2P objectives. ATN 040b is the evaluation protocol for ATN 040, Phase III of C2P.
The purpose of this study is to see if fluticasone 500mcg/salmeterol 50mcg can improve the survival of subjects with COPD and also assess the long term safety profile of this drug.
