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.
The primary objective is to compare the time to progression (TTP) of three daily doses of thalidomide (100, 200 and 400 mg) with high-dose dexamethasone in relapsed refractory multiple myeloma (MM) patients and to subsequently select the optimum thalidomide dose in terms of median TPP and toxicity.
This single arm study will assess the safety and efficacy of Avastin combined with platinum-containing chemotherapy regimens in patients with advanced or recurrent non-squamous non-small cell lung cancer (NSCLC). Avastin will be given as first-line treatment in combination with platinum-based chemotherapy or in combination with any standard of care NSCLC first-line chemotherapy used in line with the licensed national prescribing information. Eligible patients will receive Avastin (15mg/kg iv on day 1 of each 3 week cycle) concomitantly with chemotherapy. Avastin treatment will continue after completion of chemotherapy cycles until disease progression, and the target sample size is 500+ individuals.
This single arm study will assess the safety and efficacy of a regimen of Avastin plus a taxane, with or without additional chemotherapy, as first-line treatment in patients with locally recurrent or metastatic breast cancer. All patients will receive Avastin (10mg/kg iv every 2 weeks, or 15 mg/kg iv every 3 weeks) plus taxane-based chemotherapy. If taxanes are contraindicated, alternative chemotherapy (other than anthracyclines or pegylated liposomal doxorubicin) may be used. The anticipated time on study treatment is until disease progression, and the target sample size is 500+ individuals.
European physicians tend to always use the lowest dose of statins to initiate therapy even in subjects who require large reductions in cholesterol. The study evaluates if selecting the starting dose based on baseline and target LDL-C cholesterol would provide better results (ie proportion of subjects resching target)
The purpose of this study is to compare the effect of esomeprazole 20 or 40 mg once daily versus placebo on the occurrence of peptic ulcers during 26 weeks in subjects on continuous low-dose acetylsalicylic acid.
This study will investigate if the drug zoledronic acid given once yearly is safe and has beneficial effects in treating osteoporosis by reducing bone loss and fractures in men with osteoporosis.
Investigation of efficacy and safety of treatment with milnacipran in the treatment of fibromyalgia syndrome.
This study will evaluate the safety and efficacy of two different doses of Pasireotide in patients with de novo or recurrent/persistent Cushing's Disease.
The purpose of this study is to evaluate the safety and efficacy of bortezomib in participants with multiple myeloma who have previously responded to a bortezomib based therapy.
Sequential therapy with intravenous to oral moxifloxacin, was tested at 69 study centres in 17 countries to determine if this treatment regimen is safe and effective in treating hospitalized adult patients with community-acquired pneumonia. 748 patients were participated in the study over an 18 months period. Individual patient involvement in the study was approximately 4-6 weeks. Moxifloxacin was compared to a combination treatment regimen of high dose intravenous ceftriaxone plus high dose intravenous levofloxacin followed by high dose oral levofloxacin.
