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 main objective of this study is to compare a Dual Antithrombotic Therapy (DAT) regimen of 110mg dabigatran etexilate b.i.d. plus clopidogrel or ticagrelor (110mg dabigatran etexilate (DE) DAT) and 150mg dabigatran etexilate b.i.d. plus clopidogrel or ticagrelor (150mg DE-DAT) with a Triple Antithrombotic Therapy (TAT) combination of warfarin plus clopidogrel or ticagrelor plus Aspirin (ASA) <= 100mg once daily (warfarin-TAT) in patients with Atrial Fibrillation that undergo a PCI with stenting (elective or due to an Acute Coronary Syndrome). The study aims to show non-inferiority of each dose of DE-DAT when compared to Warfarin-TAT in terms of safety. Safety will be determined by comparing the rates of bleeding events, assessed using the modified International Society of Thrombosis and Haemostasis classification of Major Bleeding and Clinically Relevant Non Major Bleeding Events.
Single-shot femoral nerve block is similar to continuous epidural technique for postoperative analgesia in total knee arthroplasty
The primary objective of the study is to assess the progression-free survival (PFS) of veliparib in combination with carboplatin and paclitaxel (C/P) compared to placebo plus C/P in participants with a Breast Cancer Gene 1 or 2 (BRCA1; BRCA2) mutation in Human Epidermal Growth Factor Receptor 2 (HER2)-negative metastatic or locally advanced unresectable breast cancer. The secondary objectives of the study are to assess overall survival (OS), clinical benefit rate (CBR) through the end of Week 24, objective response rate (ORR) and PFS on subsequent therapy (PFS2) in participants treated with veliparib in combination with C/P versus placebo in combination with C/P.
This study will determine whether CT-P6 and Herceptin are equivalent in patients with early-stage breast cancer undergoing neoadjuvant chemotherapy. Our hypothesis is that the pathologic complete response rate will be equivalent in patients treated with neoadjuvant CT-P6 or Herceptin. Patients will receive 8 cycles of neoadjuvant systemic therapy and up to 10 cycles of therapy in the adjuvant setting.
This study aims to investigate posture-mobility associations in the upper quadrant by means of smartphone measurements
The purpose of this study is to determine the rate and frequency of high-grade (CTCAE v4.0 Grade 3 or higher), treatment-related, select adverse events in subjects with histologically confirmed stage III (unresectable) or stage IV melanoma and progression post prior treatment containing an anti-Cytotoxic T Lymphocyte Antigen (CTLA-4) monoclonal antibody, treated with Nivolumab (BMS-936558) at a dose of 3 mg/kg every two weeks.
Tapentadol has already been studied in adults. This study is needed to find out if tapentadol works and is safe to use in children and adolescents with long-term pain.
The purpose of this study is to test whether the application of acupuncture alters the mechanical (range of elbow extension motion) and physiological (eg, intensity and onset of discomfort, tingling feeling and/or feeling of tension or restriction of movement) responses of the neurodynamic test of nerve median in asymptomatic individuals
The first time the American Heart Association (AHA) suggested that disinfection of the gingival sulcus be performed as a complement to antibiotic prophylaxis in patients considered to be at risk of Infective endocarditis (IE) was in their protocol for the prevention of IE published in 1977. This practice was included by the AHA and adopted by other expert committees such as the British Society for Antimicrobial Chemotherapy (BSAC) in subsequent prophylactic regimens. In 1992, the BSAC specified the presentation and concentration of chlorhexidine (CHX) that should be used before starting the dental procedure: 1% gel at the gingival margin or 0.2% mouthwash for five minutes. In 1997, the AHA recognised the need to use antiseptic mouthwashes (CHX or povidone iodine) prior to dental manipulations, although they recommended against the use of gingival irrigators and against the continuous use of antiseptics in order to avoid the selection of resistant micro-organisms In 2006, the BSAC recommended a single mouthwash with 0.2% CHX gluconate (10 ml for 1 minute) before performing dental procedures associated with bacteraemia in patients at risk of IE. In contrast, in 2007, the AHA recommended against the use of any antiseptic prophylaxis protocol. In 2008, the National Institute for Health and Clinical Excellence of the United Kingdom recently performed a systematic review of the antimicrobial prophylaxis protocols for IE and reported that: "Oral chlorhexidine used as an oral rinse does not significantly reduce the level of bacteraemia following dental procedures". This conclusion was reached after analysis of numerous studies on the efficacy of prophylaxis with CHX for the prevention of post-dental manipulation bacteraemia. However, those studies presented significant methodological differences not only in the dental procedures performed, but also in the concentration of CHX applied and the method of application of the antiseptic solution (mouthwash and/or irrigation), making comparison of the results of the different series difficult. There are few studies that have analysed the efficacy of the mouthwash of 0.2% CHX (the concentration recommended by the BSAC) in the prevention of post-extraction bacteraemia. Only one study analysed the combination of local irrigation and mouthwash with chlorhexidine before dental extraction, but with a really lower concentration of CHX, only 0.02%. The objective of this study is to investigate the prevalence, duration and aetiology of bacteraemia secondary to a single tooth extraction after prophylaxis with different CHX protocols.
The objective of this Phase III study is to evaluate the efficacy of nintedanib in patients with metastatic colorectal cancer (mCRC) after failure of previous treatment with standard chemotherapy and biological agents.
