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 is to assess the potential influence of continuous intake of nintedanib on the systemic exposure of ethinylestradiol and levonorgestrel when administered in combination.
The purpose of this study is to compare the safety and efficacy of risankizumab versus placebo in participants with moderately to severely active psoriatic arthritis (PsA).
This is a Phase II, randomized, multicentre, multinational, open-label, cross-over study in adult patients who have completed neoadjuvant chemotherapy with neoadjuvant pertuzumab and trastuzumab and have undergone surgical treatment of human epidermal growth factor receptor 2 (HER2)-positive early breast cancer. The study will consist of two adjuvant treatment periods: a treatment cross-over period and a treatment continuation period. It will evaluate participant-reported preference for a subcutaneously administered fixed-dose combination formulation (FDC SC) of pertuzumab and trastuzumab compared with intravenously (IV) administered pertuzumab and trastuzumab formulations. The study will also evaluate participant-reported satisfaction with pertuzumab and trastuzumab FDC SC and health-related quality of life outcomes; healthcare professionals' perceptions of time/resource use and convenience of pertuzumab and trastuzumab FDC SC compared with pertuzumab and trastuzumab IV formulations; as well as the safety and efficacy of each study regimen.
The present study aims at refining the understanding of the effect of pregnancy on breast cancer outcomes in the specific population of BRCA mutated patients with known history of breast cancer.
The purpose of this study is to evaluate the safety and efficacy of risankizumab in adults with moderately to severely active psoriatic arthritis (PsA).
This study will compare the effectiveness of pain neuroscience education and neck/shoulder traditional exercises versus pain neuroscience education and neck/shoulder suspension training exercises for patients with chronic idiopathic neck pain (CINP).
The purpose of this study is to investigate the mean number of schizophrenia-related hospital admissions, in adult participants with schizophrenia, occurred during 12 months before and 12 months after initiation of Paliperidone Palmitate 1-month formulation treatment.
Preterm infants are especially vulnerable to gut microbiota disruption and dysbiosis since their early gut microbiota is less abundant and diverse. Several factors may influence infants' microbiota such as mother's diet, mode of delivery, antibiotic exposure and type of feeding. The main goal of this observational study is to evaluate the impact of different types of feeding (breast milk, donor human milk and preterm formulas) on the intestinal microbiota of preterm infants hospitalized in the neonatal intensive care unit (NICU) of Maternidade Alfredo da Costa (MAC). Furthermore, the influence of mode of delivery and the mother's diet, among others factors, on vertical microbiota transmission will be evaluated. After delivery, mothers will be asked to collect their own fecal samples and will be invited to complete a semi-quantitative food frequency questionnaire. Stool samples will be collected from premature infants every 7 days. DNA will be extracted from fecal samples and different bacterial genus and species will be analyzed.
An irreparable rotator cuff tear (IRCT) is a challenge, with a controversial definition and different treatment options. None of the latter are exempt of limitations and their survivorship is one of the concerns. In 2013, Mihata et al. proposed a novel treatment option: arthroscopic superior capsular reconstruction using a fascia lata autograft (FL-ASCR) harvested through an open approach. Although no harvest site dysfunction was reported, concerns about donor site morbidity discouraged the use of this type of graft. In 2015, the investigators modified the original FL-ASCR introducing a minimally invasive fascia lata harvesting technique, aiming to reproduce FL-ASCR's promising clinical results in IRCT, while reducing donor site morbidity. The investigators aim to: 1) Evaluate the mid-term outcomes and donor site morbidity impact of FL-ASCR with minimally invasive harvesting; 2) Analyze the mid-term graft integrity to determine its survivorship 3) Establish clinical and imaging graft integrity correlations to guide the future treatment algorithm.
This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, for the treatment of patients with myelofibrosis (MF) who no longer benefit from treatment with a JAK inhibitor. Inhibition of MDM2 is a novel mechanism of action in MF. This study will be conducted in 2 phases. Phase 2 will determine the KRT-232 recommended dose and dosing schedule; Phase 3 will test KRT-232 vs Best Available Therapy (BAT). Patients in the Phase 3 part of the study will be randomized 2:1 to receive either KRT-232 (Arm 1) or BAT (Arm 2). The BAT administered will be determined by the treating physician, with the option to "cross-over" to KRT-232 treatment after 6 months of BAT or if the disease worsens at any time.
