There are about 3194 clinical studies being (or have been) conducted in Portugal. 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.
Primary Objective : Compare the risk of occurrence of Grade3-4 cumulative peripheral sensory neuropathy (PSN) relative to cumulative dose of oxaliplatin between treatment group and placebo group. Main Secondary Objective : Compare the response rate (RR) between treatment group and placebo group in order to ensure that the efficacy of the chemotherapy is not compromised by the addition of xaliproden to the chemotherapeutic regimen. Other Secondary Objectives : study of the neurotoxicity parameters (Duration of oxaliplatin-induced PSN (G2,3,4); overall incidence of PSN during treatment; dose of onset of PSN ; incidence of dose-reduction and dose delay due to PSN; incidence of oxaliplatin treatment discontinuation due to PSN; change in Nerve Conduction Studies (NCS)) ; study of the safety profile (other than PSN) ; study of the chemotherapy efficacy (progression free survival, overall survival).
COMPASS-2 is a Phase 4, prospective, randomized, double-blind, placebo-controlled, event-driven study evaluating the effect of bosentan on the time to first confirmed morbidity/mortality event in patients with symptomatic PAH already receiving sildenafil therapy. Patients must have been receiving doses of sildenafil equal to or greater than 20 mg t.i.d. for at least 12 weeks prior to being randomized. The study continued until the predefined target number of morbidity/mortality events was reached.
The purpose of the study is to evaluate the safety and efficacy of two dose levels of Naglazyme in infants under the age of one year who have MPS VI by monitoring physical appearance, x-ray of the skeletal system and growth.
GW433908 (fosamprenavir; FPV)is a pro-drug of amprenavir (APV) which is more water soluble and can be formulated into a tablet with a reduced pill burden (four 700mg tablets of FPV versus sixteen 150mg capsules daily for APV. This study is designed to provide additional information on long term safety and tolerability of FPV containing regimens for those subjects who received FPV in previous GlaxoSmithKline studies.
The purpose of this study is to see if rosuvastatin compared to Atorvastatin is effective in treating ACS by decreasing the ApoB/ApoA-1 ratio and if starting statin within 24 h following the onset of the first symptoms is beneficial compared to placebo.
This is a multicentre study in which women were planned to receive either the Human Papillomavirus Vaccine (HPV) vaccine or control. Under Protocol Amendment 3, study participation will last approximately 48 months and involves a total of eleven scheduled visits. Under Protocol Amendment 4, study participation will last up to 84 months and involves a maximum of seventeen scheduled visits.
To evaluate the efficacy of pregabalin compared to placebo in the treatment of posttraumatic peripheral neuropathic pain
The purpose of this trial is to determine the comparative safety and efficacy of dabigatran etexilate 150 mg bid administered orally and warfarin as needed (pro re nata - prn) to maintain an International Normalised Ratio (INR) of 2.0-3.0 for 6 month treatment of acute symptomatic venous thromboembolism (VTE), following initial treatment (5-10 days) with a parenteral anticoagulant approved for this indication. This trial aims to demonstrate non-inferiority of dabigatran compared with warfarin in patients with acute symptomatic VTE. After achieving non-inferiority, this trial also aims to establish superiority (by means of hierarchical tests) of dabigatran over warfarin.
Study is to compare antifungal prophylaxis of Voriconazole and Itraconazole in subjects who have had a Stem Cell Transplant. The success of the end point will be measured using evidence of Infection, drug compliance and survival.
Patients will be randomised to receive either placebo or the study drug for a period of 30 weeks, in addition to their standard Parkinsonian medications. During the first 8 weeks, the patient's levodopa doses may be adjusted if necessary by the investigator. For the remainder of the 22 weeks, all medications should be kept stable. Patients will be required to attend the clinic twice during the screening period and then a further 8 times during the treatment period. They will be required to complete home diaries where they will record their motor function. In addition, their doctor will assess their Parkinson's disease during the clinic visits. There will also be blood draws for safety and pharmacokinetic and pharmacogenomics evaluation. Following the treatment and assessment period, they will return to the clinic one month later for follow up.
