There are about 1062 clinical studies being (or have been) conducted in Latvia. 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.
Study to evaluate the utility of prospective HLA-B*5701 screening on the incidence of abacavir hypersensitivity (ABC HSR) in 1800 previously ABC-naive adults with HIV-1 from Europe, Australia and other countries as applicable. The study has two (co-primary) objectives: i) to determine if screening for HLA-B*5701 prior to ABC-containing HAART results in a lower incidence of clinically-suspected HSR versus current standard of care (no genetic screening) and ii) to determine if screening for HLA-B*5701 prior to ABC-containing HAART, results in a significantly lower incidence of immunologically-confirmed HSR versus current standard of care (no genetic screening or patch testing). The study consists of up to a 28-day screening period, a randomised observation period (Day 1 through Week 6) and, for subjects experiencing a suspected ABC HSR and a subset of ABC-tolerant subjects, an epicutaneous patch test (EPT) assessment period. Eligible subjects will be randomised to one of two study arms: a Current Standard of Care Arm (no prospective genetic screening: Control) and a Genetic Screening Arm (prospective genetic screening). Subjects identified as HLA-B*5701 positive in the prospective Genetic Screening Arm will not receive ABC and will be excluded from further study. Subjects who experience suspected ABC HSR during the 6-week observation will be withdrawn from ABC-containing product and undergo EPT patch testing 6 weeks later.
The purpose of this study is to evaluate whether a higher dosage of clopidogrel with aspirin (two doses) will decrease the risk of ischemic complications (cardiac death (CV death), myocardial infarction (MI), stroke) after a percutaneous coronary intervention (PCI).
To evaluate efficacy and safety of pazopanib compared to placebo in patients with locally advanced and/ or metastatic renal cell carcinoma (RCC). Approximately 350-400 eligible patients will be stratified and randomized in a 2:1 ratio to receive either 800 mg pazopanib once daily or matching placebo. The study treatment will continue until patients experience disease progression, unacceptable toxicity or death. Primary objective of the study is to evaluate and compare the two treatment arms for progression-free survival. Principal secondary objective is to evaluate and compare the two treatment arms with respect to overall survival. Other objectives are overall response rate [complete response (CR) + partial response (PR)], rate of CR + PR + 6 months stable disease, and the incidence, severity and causality of adverse events and serious adverse events. Safety and efficacy assessments will be regularly performed on all patients. An Independent Data Monitoring Committee will be established to monitor safety during the course of the study and to evaluate interim efficacy data on overall survival.
The purpose of this study is to assess if 10 mg BAY 59-7939, taken once daily as a tablet, is safe and can help prevent blood clots forming after a hip replacement operation.
The purpose of this study is to evaluate the safety and efficacy of alogliptin, once daily (QD), taken in combination with pioglitazone in adults with type 2 diabetes mellitus.
The purpose of this study is to assess the ability of once-daily (QD) treatment with dexlansoprazole modified release (MR) 30 mg and 60 mg or placebo in maintaining healing of erosive esophagitis (EE).
This 3 arm study will compare the efficacy and safety of beta-lactam with that of 'standard care' in patients with complicated skin and skin structure infections requiring hospitalization. Patients will be randomized to receive 1)beta-lactam 750mg iv q8h 2)beta-lactam 1500mg iv q8h or 3)'standard care' [PRP (nafcillin or flucloxacillin) or vancomycin, plus aztreonam or ciprofloxacin]. The anticipated time on study treatment is <3 months and the target sample size is 100-500 individuals.
The primary objective is to compare the antidepressant efficacy, safety, and tolerability of DVS SR versus placebo in subjects with Major Depressive Disorder. Additional objectives include testing both general and functional quality-of-life outcomes and satisfaction with therapy reported by the subject.
This double-blind, stratified, parallel group study is to determine whether aiming for 'Total control' results in better airway hyper-responsiveness than maintaining the treatment level at which 'Well-controlled' asthma was achieved. The primary endpoint is the mean change in PC20 methacholine. Well controlled subjects (as assessed after a 12 week run-in period) will enter a 24 week treatment period during which they will record PEF(Peak Expiratory Flow), symptoms, rescue beta2-agonist use over 24 hours, night time awakenings, asthma exacerbations, emergency visits due to asthma and Adverse Events. At every visit lung function measurements and airway hyper-responsiveness will be measured.
Patients will receive injections of GSK 249553 vaccine . Appropriate tests will be performed to assess the safety of the treatment and its ability to induce an immune response.
