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.
A study designed to evaluate the safety of crovalimab with eculizumab in participants with PNH currently treated with complement inhibitors. This study will enroll approximately 190 participants.
In this study, we will assess the efficacy and safety of a reduced dose of thrombolytic therapy given in addition to low-molecular-weight heparin in patients with intermediate-high-risk acute pulmonary embolism. Half of participants will receive thrombolytic treatment, while the other half will receive a placebo.
This study is designed to assess the safety and efficacy of lenvatinib in combination with pembrolizumab versus standard of care (SOC) chemotherapy, and to also assess the safety and efficacy of lenvatinib monotherapy in participants with recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC) that have progressed after platinum therapy and a programmed cell death protein 1 (PD-1) or anti-programmed death ligand 1 (PD-L1) inhibitor. The primary hypothesis is that lenvatinib + pembrolizumab is superior to SOC chemotherapy with respect to ORR per modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by blinded independent central review.
This is a multicenter prospective study that aims to investigate the clinical impact of SARS-CoV-2 infection in pregnant women, pregnancy outcomes and perinatal transmission.
This study will be conducted to evaluate the efficacy, safety, and tolerability of AVP-786 (deudextromethorphan hydrobromide [d6-DM]/quinidine sulfate [Q]) compared to placebo for the treatment of agitation in participants with dementia of the Alzheimer's type.
Dysbiosis of gut microbiota is associated with the pathophysiology of type 2 diabetes. Mediterranean diet has been indicated as a dietary pattern that promote the integrity of gut barrier and that has positive impact in the metabolic control of subjects with type 2 diabetes. This is a 12-week, single-arm clinical study that aims to evaluate if the effect of Mediterranean diet in metabolic control of these subjects is mediated by gut microbiota. Subjects will receive personalized nutrition counseling where Mediterranean diet will be promoted.
This is a multicentre, open-label, parallel arms, phase IIII study that randomises patients with locally recurrent rectal cancer in a 1:1 ratio to receive either induction chemotherapy followed by neoadjuvant chemoradiotherapy and surgery (experimental arm) or neoadjuvant chemoradiotherapy and surgery alone (control arm)
The aim of this study is to explore the effect of a low starch diet (reduction of at least 40%) in the gut bacteria modulation, especially Klebsiella pneumoniae, and its relation to disease activity, functional impairment and quality of life in patients with Ankylosing Spondylitis (AS).
With the main goal of generalising findings into Virtual Reality-Neurofeedback-Motor imagery (VR-NF-MI) system, this project aims to develop a new motor rehabilitation tool, for the upper limb, allied to the use of rising of information and communication technologies (ICT). By identifying correlations on the neural activity, during motor imagery and through brain imaging (fMRI), with distinct training protocols and feedback, these protocols are developed to create user-specific models that later can be used in NF-MI rehabilitation sessions.
In the last 10 years, severe acute respiratory infection (SARI) was responsible of multiple outbreaks putting a strain on the public health worldwide. Indeed, SARI had a relevant role in the development of pandemic and epidemic with terrible consequences such as the 2009 H1N1 pandemic which led to more than 200.000 respiratory deaths globally. In late December 2019, in Wuhan, Hubei, China, a new respiratory syndrome emerged with clinical signs of viral pneumonia and person-to-person transmission. Tests showed the appearance of a novel coronavirus, namely the 2019 novel coronavirus (COVID-19). Two other strains, the severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) have caused severe respiratory illnesses, sometimes fatal. In particular, the mortality rate associated with SARS-CoV and MERS-CoV, was of 10% and 37% respectively. Even though COVID-19 appeared from the first time in China, quickly it spread worldwide and cases have been described in other countries such as Thailand, Japan, South Korea, Germany, Italy, France, Iran, USA and many other countries. An early paper reported 41 patients with laboratory-confirmed COVID-19 infection in Wuhan. The median age of the patients was 49 years and mostly men (73%). Among those, 32% were admitted to the ICU because of the severe hypoxemia. The most associated comorbidities were diabetes (20%), hypertension (15%), and cardiovascular diseases (15%). On admission, 98% of the patients had bilateral multiple lobular and sub-segmental areas of consolidation. Importantly, acute respiratory distress syndrome (ARDS) developed in 29% of the patients, while acute cardiac injury in 12%, and secondary infection in 10%. Invasive mechanical ventilation was required in 10% of those patients, and two of these patients (5%) had refractory hypoxemia and received extracorporeal membrane oxygenation (ECMO). In a later retrospective report by Wang and collaborators, clinical characteristics of 138 patients with COVID-19 infection were described. ICU admission was required in 26.1% of the patients for acute respiratory distress syndrome (61.1%), arrhythmia (44.4%), and shock (30.6%). ECMO support was needed in 11% of the patients admitted to the ICU. During the period of follow-up, overall mortality was 4.3%. The use of ECMO in COVID-19 infection is increasing due to the high transmission rate of the infection and the respiratory-related mortality. Therefore, the investigators believe that ECMO in case of severe interstitial pneumonia caused by COVID could represent a valid solution in order to avoid lung injuries related to prolonged treatment with non-invasive and invasive mechanical ventilation. In addition, ECMO could have a role for the systemic complications such as septic and cardiogenic shock as well myocarditis scenarios. Potential clinical effects and outcomes of the ECMO support in the novel coronavirus pandemic will be recorded and analyzed in our project. The researchers hypothesize that a significant percentage of patients with COVID-19 infection will require the utilize of ECMO for refactory hypoxemia, cardiogenic shock or septic shock. This study seeks to prove this hypothesis by conducting an observational retrospective/prospective study of patients in the ICU who underwent ECMO support and describe clinical features, severity of pulmonary dysfunction and risk factors of COVID-patients who need ECMO support, the incidence of ECMO use, ECMO technical characteristics, duration of ECMO, complications and outcomes of COVID-patients requiring ECMO support.
