There are about 4010 clinical studies being (or have been) conducted in Argentina. 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 is a randomized, double-blind, placebo- and active-controlled study of a new experimental drug called darusentan. Darusentan is not currently approved by the United States Food and Drug Administration (FDA), which means that a doctor cannot prescribe this drug. The purpose of this study is to determine if darusentan is effective in reducing systolic and diastolic hypertension despite treatment with full doses of three or more antihypertensive drugs, including a diuretic. Subjects will be randomized to darusentan (optimized dose), an active comparator, or placebo, administered orally. The treatment period for this trial is 14 weeks.
This is a double-blind, active-controlled, long-term study of a new experimental drug called darusentan. Darusentan in not currently approved by the United States Food and Drug Administration (FDA), which means that a doctor cannot prescribe this drug. The purpose of this study is to evaluate the long-term safety of darusentan (optimized dose) as compared to an active control, administered orally.
The primary purpose of this study is to evaluate the blood pressure lowering effects of ramipril, an FDA-approved drug for the treatment of hypertension in adults, in children and adolescents aged 6 to 16 years with hypertension.
Primary purpose of this study is to compare the efficacy and safety of two different nevirapine (Viramune) dosing regimens (once daily (QD) and twice daily (BID) application) and of atazanavir/ritonavir (Reyataz/Norvir), all on an emtricitabine/tenofovir disoproxil fumarate (DF) (Truvada) background. Patients will receive either nevirapine (NVP) 200 mg twice daily, or NVP 400 mg once daily , or ritonavir-boosted atazanavir (ATZ/r), all in combination with emtricitabine (FTC) and tenofovir DF (TDF). All patients receiving NVP will start at 200 mg once daily for 2 weeks, because it has been demonstrated that this lead-in dosing regimen reduces the frequency of NVP-induced rash. At Visit 3 (Week 2), patients increase the NVP dose to either 200 mg twice daily or to 400 mg once daily. Patients receiving ATZ/r will be treated with ATZ 300 mg once daily, boosted by 100 mg ritonavir (RTV) once daily. Background antiretroviral therapy for all patients consists of one tablet of Truvada. Treatment duration is 48 weeks (primary endpoint) with an extension to 144 weeks. Patients may also participate in the metabolic sub-study, comparing NVP and ATZ/r for signs and symptoms of lipodystrophy and serum lipid/glycaemic abnormalities.
The primary purpose of this study is to evaluate whether treatment with (SEROQUEL SR) quetiapine fumarate sustained release (SR) for 9 weeks compared to placebo will improve depressive symptoms in elderly patients with major depressive disorder. PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation was changed to XR after consultation with FDA.
The objective of this study is to evaluate the efficacy and safety of 12 weeks treatment with tiotro pium HandiHaler® 18 mcg daily compared to Combivent® MDI CFC Inhalation Aerosol 2 actuations qid in COPD patients currently prescribed Combivent® MDI.
The purpose of this study is to compare Overall Survival (OS), Progression Free Survival (PFS), objective tumor response rate, duration of response, and safety in patients treated with E7389 versus the Treatment of Physician's Choice (TPC) in patients with locally recurrent or metastatic breast cancer.
The purpose of this study is to prospectively assess the long-term outcomes (benefits and risks) associated with entecavir (ETV) therapy as compared to other antivirals approved for the treatment of chronic HBV infection. For the China substudy, patients randomized to entecavir will have safety and efficacy assessments performed during the first year of the study.
This is an open-label, international, multi-center study designed to provide access to pazopanib for subjects who have been enrolled in the Phase III renal cell carcinoma study (VEG105192) and have progressed on placebo. Subjects will receive 800 mg pazopanib once daily. The study treatment will continue until subjects experience disease progression, unacceptable toxicity, withdrawal of consent, or death. The primary objective of the study is to evaluate the safety and tolerability of pazopanib for the treatment of renal cell carcinoma. The secondary objectives of the study are to assess response rate (defined as complete response or partial response), progression-free survival, and overall survival. Response rates will be collected per investigator assessment (no central review). Subjects will have a CT/MRI scan every 6 weeks until week 24 and every 12 weeks thereafter.
The primary objective of this study is to assess whether a single dose of rhBMP-2/CPM administered at the fracture site via percutaneous injection, in combination with standard of care, accelerates fracture union and return to normal function in subjects who have a closed diaphyseal tibial fracture when compared to standard of care alone.
