There are about 238 clinical studies being (or have been) conducted in Dominican Republic. 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 the study is to examine the effects of two contraceptive methods and the menstrual cycle on the pharmacokinetics, pharmacodynamics of tenofovir 1% gel and the effect of the contraceptive methods on markers of mucosal safety.
The purpose of the study is to obtain data on the pharmacokinetics (PK) and pharmacodynamics (PD) and immune system effect of the BAT24 dosing regimen versus daily and pericoital dosing regimens with vaginal use of tenofovir 1% gel after a single sex act and after multiple sex acts.
This is a randomized, double-blind study comparing 0.1% NVC-422, 0.5% NVC-422 and 1.5% NVC-422 topical gel in children with impetigo.
This study is to characterize the effect of cobicistat-based regimens on parameters of renal function in subjects with HIV infection and who have mild to moderate renal impairment, and to assess the safety and tolerability of the regimens in order to generate appropriate dosing recommendations.
This study will describe the long-term safety and effectiveness, treatment patterns,and patient reported quality of life associated with ranibizumab treatment in routine clinical practice for all approved indication included in the local product label.
It has been proposed that levonorgestrel (LNG) in a vaginal gel could be used as an 'on demand' contraceptive when used before coitus. Levonorgestrel was selected as it is a component of many approved oral contraceptive pills and also it is the active agent in Plan B, an FDA-approved regimen for emergency contraception (EC). In previous studies it was demonstrated that an LNG vaginal gel was absorbed and was effective in preventing follicular rupture. The overall proportion of cycles with lack of follicular rupture within 5 days of LNG administration or with ovulatory dysfunction (follicle rupture preceded by an inadequate LH surge) was 96% for LNG gel and 39% in the inert gel cycles (control group).
The primary objective of this study is to compare the effect of two vaginal applicators, delivering the candidate microbicide Tenofovir, on symptoms and signs of irritation of the external genitalia, cervix and vagina as seen on colposcopy after seven days of twice daily use. The secondary objectives are to: 1. Evaluate and compare the dosing accuracy and precision of the user-filled applicator and pre-filled applicator with the candidate microbicide, Tenofovir. 2. Compare the acceptability of the user-filled applicator with the pre-filled applicator.
This study is designed to evaluate the safety and immunogenicity of new formulations of GSK Biologicals' DTPa-HBV-IPV/Hib vaccine (GSK217744) when administered as a primary vaccination course to healthy infants at 2, 3 and 4 months of age.
Tobacco use and tobacco-caused illnesses and death are increasing in developing countries globally, so it is critical to study these countries in order to effectively address the tobacco epidemic. The proposed project will test the effectiveness of community-based interventions for secondhand smoke and quitting smoking in eight underserved communities in the Dominican Republic. The project will also partner with communities and national and international groups to determine whether the methods and interventions from this study in the Dominican Republic can also be used to help other countries in the region and underserved groups in the United States.
This study is designed to test the efficacy of an investigational influenza vaccine, in children compared to Havrix®, a licensed Hepatitis A virus vaccine. This study will also evaluate the immunogenicity and safety of the investigational vaccine.
