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 aim of this study is to do an evaluation of the clinical profile of depression in HCV patients (newly diagnosed and treatment naïve), and in these same individuals, 24 weeks after the beginning of IFN+Ribavirin therapeutics (n=100). To characterize depression associated to HCV with and without interferon (IFN), the investigators will use clinical, behavioral, biochemical and genetic markers, and to distinguish their different symptomatologic dimensions. The control group will be composed by 100 individuals with Major Depression diagnosis, and not from the general population, because the investigators are not trying to study the incidence of depression in general population, but to characterize the clinical profile of patients with HCV (IFN+Ribavirin) compared to major depression. Thus, the investigators will total 300 evaluations in 200 individuals, 100 from each group, and considering that the clinical group will be evaluated before the therapeutics and re-evaluated 24 weeks after its beginning. Hypotheses 1. Depression in individuals affected by HCV is associated to genetic vulnerability. 2. Genetic vulnerability increases the risk of depression when IFN therapeutics is used. 3. Depression associated to infection by HCV presents a symptomatological profile that is different from general depression, which is maintained with IFN therapeutics. 4. A higher state of depression in the beginning of a treatment, if not treated, is a risk factor to abandoning therapeutics. 5. When comparing genders, women present a more severe symptomatological profile than men.
This study will compare the safety and efficacy of the 700 ug dexamethasone intravitreal implant with ranibizumab 0.5 mg intravitreal injections in patients with diabetic macular edema (DME).
Study assessing cognitive function and physical activity in people with relapsing remitting multiple sclerosis.
The purpose of this study is to determine the overall cutaneous response rate (participants who achieve a complete response or partial response) based on the modified severity weighted assessment tool criteria.
The purpose of this study is to demonstrate the efficacy of TMC435 in combination with peginterferon (PegIFN) + ribavirin (RBV) by means of establishing its non- inferiority compared to an approved regimen of telaprevir + PegIFN + RBV in patients who have previously failed PegIFN.
The purpose of this study is to evaluate the efficacy, safety and tolerability of belimumab administered subcutaneously (SC) to adult subjects with Systemic Lupus Erythematosus (SLE).
This is a phase 3, randomized, 2-arm, open-label, international trial evaluating alisertib compared with single-agent treatment, as selected by the investigator from the offered options of pralatrexate or gemcitabine or romidepsin, in participants with relapsed or refractory peripheral T-cell lymphoma (PTCL). Note: romidepsin was not used as a single-agent comparator outside the United States of America (USA) as supply was not available.
The primary objective of the study is to assess the effect of long-term treatment with prolonged-release (BIIB041) (fampridine) 10 mg twice daily on the physical component scale (PCS) of the Short Form (36) Health Status Questionnaire (SF-36) as reported by treatment responders. The secondary objectives of this study are to compare the change in the PCS of the SF-36 between treatment responders and non-responders, to evaluate change from baseline in additional QoL measures among treatment responders as well as changes from baseline in treatment responders versus non-responders and to assess the safety and tolerability of prolonged-release fampridine 10 mg twice daily.
The primary objective of the study is to collect additional safety data including the incidence rate of seizure and other specific Adverse Events (AEs) of interest from participants taking Fampyra in routine clinical practice. The secondary objectives of this study are to characterize utilization patterns of Fampyra in routine clinical practice, to assess the effectiveness of risk minimization measures as described in the risk management plan for Fampyra, to assess the change over time in participant self-reported evaluation of the physical and psychological impact of Multiple Sclerosis (MS) while taking Fampyra and to assess the change over time in physician assessment of walking ability in participants taking Fampyra (MS participants only).
The purpose of this study is to evaluate the safety and tolerability of TMC435 along with pegylated interferon alpha-2a (PegIFNα-2a) and ribavirin (RBV) triple therapy in hepatitis C virus genotype-1 infected subjects, co-infected with human immunodeficiency virus-type 1, and to evaluate the number of patients with sustained virologic response (SVR) at 12 weeks after the planned end of treatment.
