There are about 32 clinical studies being (or have been) conducted in Paraguay. 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.
Objective: To establish the efficacy of laser application with chemical treatment in dental bleaching compared to chemical treatment alone. Methods: The investigators conducted a randomized controlled trial (RCT), single blind (evaluator), in 24 patients randomized to laser and chemical intervention (12) or chemical intervention aloe (12). The commercial products used were Whiteness Hp 35% Hydrogen Peroxide and the LASER of DCM Equipments. The trial outcome measures were obtained using the Vita EasyShade Spectrophotometer and the International CIELCh system. To stablish differences before vs. after treatments and between groups, the T test and chi2 tests were applied.
Study conducted to confirm phrenic nerve stimulation using the a transvenous Phrenic Nerve Stimulator in the left jugular vein.
A single-arm study to observe NeuroTronik Cardiac Autonomic Nerve Stimulation (CANS) Therapy System hemodynamic and other physiologic effects.
The objective of the BOSS Study is to assess acute anatomical and geometric annular and ventricular changes that occur when strategically positioned an external inflatable chambers are applied to the outside of the heart.
A single-center feasibility study in patients undergoing cardiac catheterization, to investigate the acute hemodynamic effects of transvenous cardiac autonomic nerve stimulation.
This is a randomized, double blind, active control study of PRX-102 (pegunigalsidase alfa) in Fabry disease patients with impaired renal function. Patients treated for approximately 1 year with agalsidase beta and on a stable dose for at least 6 months will be screened and then randomized to continue treatment with 1mg/kg agalsidase beta or to treatment with 1 mg/kg of PRX-102. The identity of the enzyme will be blinded to the patient and the investigator. Patients will receive intravenous infusions every two weeks. Patients will be randomized in a 2:1 ratio of PRX-102 to agalsidase beta. Randomization will be stratified by urinary protein to creatinine ratio (UPCR) of < or ≥ 1 g/g by spot urine sample. No more than 50% of the patients will be female.
Study conducted to confirm phrenic nerve stimulation using the Lungpacer LIVE Catheter, confirm capture of the diaphragm and confirm that the diaphragm can be paced in synchrony with mechanical ventilator breaths.
Multi center evaluation of the Millipede IRIS for treatment of clinically significant mitral regurgitation in subjects determined appropriate for mitral valve surgery.
Few randomized studies have focused on the optimal management of non-ICU patients with type 2 diabetes in Latin America. Objective: Compare safety and efficacy of a basal bolus regimen with analogs and human insulins in general medicine patients admitted to a University Hospital in Asuncion, Paraguay.
Study of RTXM83 plus CHOP chemotherapy versus a rituximab plus CHOP therapy in patients with Non Hodgkin's lymphoma The primary endpoint of the investigation is to determine if the response rate obtained with RXM83 combined with CHOP is non inferior to the response rate obtained with reference rituximab combined with CHOP The present study is a non inferiority trial and the study hypothesis is the following: H0: pc ≥ pe + δ vs. H1: pc < pe + δ where, pe: proportion of successes in the experimental group (RTXM83+CHOP) pc: proportion of successes in the control group (Reference Rituximab+CHOP) Type I error: the difference pc-pe is less than δ when in fact the difference is greater than or equal to δ ie, the investigators choose the experimental treatment when the control treatment is actually substantially better. Type II error: the difference -pe is greater than or equal to δ when it is actually lest than δ ie, the investigators choose the control treatment when the experimental treatment is essentially just as good.
