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 primary objectives of this study are to compare the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) fixed dose combination (FDC) for 8 weeks with that of SOF/VEL FDC for 12 weeks in direct-acting antiviral-naive participants with chronic hepatitis C virus (HCV) infection.
The primary objectives of this study are to evaluate the safety and efficacy of treatment with sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) in adults with chronic hepatitis C virus (HCV) infection who have previously received treatment with direct-acting antiviral therapy. Participants randomized to placebo may be eligible for deferred treatment with active SOF/VEL/VOX.
The main objective will be to evaluate the dose-response of ACT-132577 (aprocitentan) on diastolic blood pressure (DBP) in participants with grade 1 or 2 essential hypertension. Secondary objectives will be to evaluate the dose-response of ACT-132577 on: systolic blood pressure (SBP); control and response rate of blood pressure; 24-hour ambulatory blood pressure monitoring (ABPM) and to evaluate the safety and tolerability of a once daily oral regimen of 4 doses of ACT-132577.
The primary objective of this study is to evaluate the efficacy of switching from a regimen of dolutegravir (DTG) and abacavir/lamivudine (ABC/3TC) or a fixed dose combination (FDC) of abacavir/dolutegravir/lamivudine (ABC/DTG/3TC) to a FDC of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus continuing DTG and ABC/3TC as the FDC ABC/DTG/3TC in virologically suppressed Human Immunodeficiency Virus- 1 (HIV-1) infected adults.
The primary objective of this study is to evaluate the efficacy of switching to a fixed-dose combination (FDC) of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus continuing on a regimen consisting of boosted atazanavir (ATV) or darunavir (DRV) plus either emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) or abacavir/lamivudine (ABC/3TC) in HIV-1 infected adults who are virologically suppressed.
This is a multicenter, randomized, double-blind study of the efficacy and safety of iclaprim compared to vancomycin for the treatment of skin and skin structure infections.
This study will evaluate whether an early positive response to once-monthly oral ibandronate in treatment-naive participants with postmenopausal osteoporosis is predictive of efficacy later in treatment. The anticipated time on study treatment is 6 months, and the target sample size is 360 individuals.
The main purpose of this study is to evaluate the efficacy and safety of the study drug known as dulaglutide when added to sodium-glucose co-transporter 2 (SGLT2) inhibitors in participants with type 2 diabetes mellitus.
This is a phase 3, multicenter, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of DX-2930 in preventing acute angioedema attacks in patients with Type I and Type II HAE.
This study was done to see if the combination of two anti-HIV medicines, dolutegravir (DTG, Tivicay) and lamivudine (3TC, Epivir) taken once a day, provide a safe, effective, and well-tolerated treatment for HIV. DTG is a type of HIV medicine called an integrase inhibitor; 3TC is a type of HIV medicine called a reverse transcriptase inhibitor. DTG works by blocking integrase and 3TC works by blocking reverse transcriptase, two HIV proteins (enzymes). This prevents HIV from multiplying and lowers the viral load (amount of HIV in the blood). Both DTG and 3TC are currently part of Food and Drug Administration (FDA) recommended regimens along with a third active drug. Since some HIV medicines have side effects and are costly, there is interest in whether HIV can be successfully controlled with fewer than three HIV drugs.
