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.
This study will compare the ability of fosamprenavir 700 mg with ritonavir 100 mg twice a day or lopinavir 400 mg with ritonavir 100 mg twice a day both combined with a fixed dose combination tablet of abacavir 600 mg and lamivudine 300 mg once a day to suppress virus levels of HIV to less than 400 copies/mL of blood. In addition we will study the safety and tolerability of these compounds over the 48 week study period in patients naive to anti-HIV therapy.
RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Oblimersen may increase the effectiveness of docetaxel by making tumor cells more sensitive to the drug. PURPOSE: This randomized phase II trial is studying how well giving docetaxel together with oblimersen works compared to docetaxel alone in treating patients with hormone-refractory adenocarcinoma (cancer) of the prostate.
To determine if linezolid is superior to vancomycin in the treatment of nosocomial (acquired in the hospital) pneumonia due to Methicillin Resistant Staphylococcus Aureus (MRSA) in adult subjects. Subjects entered in to the study will have proven healthcare-associated methicillin-resistant Staphylococcus aureus pneumonia which will be treated with either linezolid or vancomycin.
The purpose of this clinical research study is to learn if BMS-247550 added to the approved therapy of capecitabine (Xeloda) provides measurable clinical benefits over capecitabine alone in women with metastatic breast cancer. Patients should have previously received an anthracycline and a taxane. The safety of this treatment will also be studied.
This is a Phase 3, multicenter, open-label, comparator-controlled trial comparing the effect of exenatide twice daily to twice daily biphasic insulin aspart on glycemic control, as measured by hemoglobin A1c (HbA1c).
This is a multicenter, comparator-controlled, open-label, randomized, two-arm, parallel trial to compare the effect of exenatide twice daily and insulin glargine on glycemic control, as measured by hemoglobin A1c (HbA1c).
The purpose of this clinical trial is to determine if RPR109881 is a better treatment than capecitabine (Xeloda) for advanced breast cancer in patients that no longer benefit from docetaxel and/or paclitaxel.
The primary objective of the TMC114-C215 study is to evaluate the safety and tolerability of TMC114/RTV over time. The secondary objectives are to evaluate the antiviral activity over time and to evaluate the immunological effect over time.
This study will assess the efficacy and safety of intravenous (iv) or subcutaneous (sc) Mircera, administered with pre-filled syringes, as maintenance treatment for renal anemia in chronic kidney disease patients on dialysis who were previously receiving iv or sc epoetin. The anticipated time on study treatment is 3-12 months and the target sample size is 100-500 individuals.
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. Anastrozole may be effective in preventing breast cancer. PURPOSE: This randomized clinical trial is studying how well anastrozole works in preventing breast cancer in postmenopausal women who are at increased risk for the disease.
