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.
To evaluate the efficacy and safety of lenalidomide, rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R2-CHOP) chemotherapy versus placebo, rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (placebo-R-CHOP) chemotherapy in patients who have previously untreated ABC type DLBCL.
Single centre, two-way crossover, randomised, open-label study in 20 healthy female volunteers.The volunteers received an oral single-dose of a combined contraceptive containing with an oral once daily dose of 1200 mg of BIA 2-093
The present study is designed to test the hypothesis that Intra-Articular Hyaluronic Acid (IAHA) is superior to placebo in slowing structural progression and on long term symptomatic effect in primary knee Osteoarthritis (OA) patients. The investigators will perform a multicenter double-blind, randomized, placebo-controlled, parallel group trial.
Single centre, open-label, randomised, three-way crossover study in 18 healthy subjects (9 males and 9 females). The study consisted of three consecutive single-dose treatment periods separated by a washout period of 7 days or more. On each treatment period, the volunteers received a single dose of BIA 2-093 800 mg, orally.
This study was conducted to explore a new therapy for anemia in participants with end stage renal disease (ESRD) on dialysis. Anemia is a reduced number of red blood cells or hemoglobin. Hemoglobin (which contains iron) is important for the transport of oxygen in your blood. The purpose of this study was to evaluate if roxadustat is effective and safe in the maintenance treatment of anemia in ESRD participants on stable dialysis. Roxadustat was compared to epoetin alfa and darbepoetin alfa, commercially available medicines for treatment of anemia.
The purpose of this study was to determine whether treatment with tamoxifen or a non-steroidal aromatase inhibitors (NSAI) + goserelin + LEE011 prolonged progression-free survival (PFS) compared to treatment with tamoxifen or a NSAI + goserelin + placebo in premenopausal women with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer.
Medtronic , Inc. is sponsoring the World-wide Randomized Antibiotic Envelope Infection Prevention Trial (WRAP-IT), a randomized, prospective, multi-center, single blinded, post-market, interventional clinical study. This study will evaluate the ability of the TYRX™ envelope to reduce major Cardiac Implantable Electronic Device (CIED) infections through 12-months post-procedure following CIED generator replacement, upgrade, revision, or de novo cardiac resynchronization therapy defibrillator (CRT-D) implant. Additionally, this large device study provides the unique opportunity to prospectively characterize the performance of Medtronic's lead monitoring features in subjects whose CIED system includes a transvenous right ventricular (RV) defibrillation lead. Finally, the WRAP-IT study will serve as a post-approval study for those geographies requiring a post-approval study of the TYRX™ envelope.
BIOLUX P-III is a prospective, international, multi-centre, postmarket all-comers registry to collect clinical performance data on the Passeo-18 Lux paclitaxel releasing balloon catheter in the treatment of atherosclerotic disease of the infrainguinal arteries.
This is a two-arm, randomized, double-blind, multicenter, pre-operative study to evaluate the effect of combining letrozole and GDC-0032 (also known as taselisib) versus letrozole and placebo in postmenopausal women with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2 (HER2) untreated, Stage I-III operable breast cancer. Participants will be randomized into one of the two treatment arms with a 1:1 randomization ratio. Letrozole at 2.5 milligrams (mg) will be dosed once daily plus either Taselisib at 4 mg (two 2-mg tablets) or placebo on a 5 days-on/ 2 days-off schedule for a total of 16 weeks.
This study intends to determine whether continuous positive airway pressure (CPAP) can reduce arterial stiffness (measured by pulse wave velocity) in nonsleepy as well as in sleepy patients with obstructive sleep apnea .
