There are about 10004 clinical studies being (or have been) conducted in Brazil. 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.
There is evidence about the effects of photobiomodulation therapy (PBMT) alone and combined with static magnetic field (PBMT-sMF) on skeletal muscle fatigue, physical performance and post-exercise recovery in different types of exercise protocols and sports activity. However, it is unknown the effects of PBMT-sMF to improve the subsequent performance after a first set of exercise. Therefore, the aim of this study was to investigate the effects of PBMT-sMF, applied between two sets of exercises, on the subsequent physical performance.
This is a randomized clinical trial with women with lymphedema secondary to breast cancer. The intervention will consist of the use of self-adjusting clothing versus compressive bandaging (routine treatment of the institution). Self-adjusting clothing is expected to be more effective for the treatment of lymphedema reduction, when compared to standard treatment, in addition to promoting a better quality of life and functionality.
This is an open-label study to evaluate the safety and preliminary efficacy of Codivir in 12 mild or moderate COVID-19 patients and onset of symptoms within 72h prior to their inclusion. Treatment will begin in the hospital, participants will be discharged at Day 4 and continue the treatment up to Day 10 at home and followed up to day 28.
This is a phase III study of efficacy and safety of secukinumab versus placebo, in combination with glucocorticoid taper regimen, in patients with giant cell arteritis (GCA)
Cancer is a condition where cells in a specific part of body grow and reproduce uncontrollably. Non-small cell lung cancer (NSCLC) is a solid tumor, a disease in which cancer cells form in the tissues of the lung. The purpose of this study is to determine if telisotuzumab vedotin works better than docetaxel and to assess how safe telisotuzumab vedotin is in adult participants with NSCLC who have previously been treated. Change in disease activity and adverse events will be assessed. Telisotuzumab vedotin is an investigational drug being developed for the treatment of NSCLC. Participants will be randomly assigned a treatment of Teliso-V or Docetax at an 1:1 ratio. Each group receives intravenous (IV) infusion of telisotuzumab vedotin or IV infusion of docetaxel. Approximately 698 adult participants with c-Met overexpressing NSCLC will be enrolled in the study in approximately 250 sites worldwide. Participants will receive IV telisotuzumab vedotin every 2 weeks or docetaxel every 3 weeks until meeting study drug discontinuation criteria. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
The RTXM83-AC-01-11 study evaluated efficacy and safety outcomes in relation to the use of Vivaxxia during 6 treatment cycles (at the investigator's discretion, up to 8 treatment cycles could be administered), followed by 9 months of follow-up. , this follow-up time being sufficient for the analysis of non-inferiority in relation to the reference medicine. However, data on late events of efficacy and safety are of great value to contribute to a robust clinical response and to strengthen confidence in the use of biosimilar medicines. For this reason, Libbs Farmacêutica proposes this retrospective observational study to collect data on late outcomes of the pivotal study that directed the approval of the biosimilar rituximab (Vivaxxia) from the research participants from Brazil. The present retrospective observational study LB2002 will sub-analyze selected results of efficacy and safety from study RTXM83-AC-01-11 in participants over 18 years of age randomized in Brazil, totaling 28 participants, in addition to evaluating late efficacy and safety outcomes. Information on subsequent treatment / protocol should also be collected for participants who have progressive or recurrent disease, instituted by research centers under these conditions. The proposal is to compare descriptively the selected outcomes of efficacy and safety of these participants with the same outcomes selected for the global population in the RTXM83-AC-01-11 study, and also provide late safety and effective data important for anti-neoplastic processes.
Clinical, control, double-blind, randomized experimentation with N-acetylcysteine and bromhexine for COVID-19.
Since the first report of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of concern (VOC) P.1 in Manaus, Brazil, a rapid spread of this lineage across the country has been observed. Recent studies indicate that this variant is associated with higher transmissibility; it is not known whether it is associated with clinical severity and higher mortality rates. This is a retrospective cohort study carried out at Hospital de Clínicas de Porto Alegre. Adult patients aged 18 years or more and 65 years or less who were admitted to the hospital due to symptomatic COVID-19 from June 2020 to May 2021 and had a reverse transcriptase-polymerase chain reaction (RT-PCR) cycle threshold value for either SARS-CoV-2 N1 or N2 target ≤ 25 were eligible to the study. Samples from 86 patients (43 from June 2020 to November 2020 and 43 from February 2021 to May 2021) were sequenced for further evaluation. These dates were defined since the emergence of P.1 lineage in late January. Clinical data regarding ventilatory support, date of onset of symptoms, laboratory findings and mortality were collected from each patient. This retrospective cohort aims to assess whether the number of days needed for supplementary oxygen either by noninvasive ventilation or high-flow nasal cannula from onset of symptoms differs among patients infected with the P.1 SARS-CoV-2 variant and those infected with other variants.
Rheumatoid arthritis (RA) is a chronic inflammatory disease that affects the joints, causing pain, edema, physical disability and poor quality of life. In addition, RA patients are at increased risk of developing cardiovascular disease (CVD) and premature death. The most effective pharmacological treatment is the use of biological agents that inhibit the action of specific substances, such as interleukin 6 (IL-6) and tumor necrosis factors (TNF). Physical exercise is considered a first-line non-pharmacological treatment in RA, improving inflammatory and metabolic profile, functional capacity, fatigue and preventing the onset of CVD. There is evidence that IL-6, when secreted as a result of exercise, brings several benefits. However, there is no study investigating the interaction between biological IL-6 blocking agents and exercise on metabolic responses, such as insulin sensitivity and glucose uptake, in patients with RA. To answer this question, adult women diagnosed with RA and healthy controls will be recruited for an acute session of exercise. RA patients will be divided into 2 groups, according to the pharmacological treatment (tocilizumab or anti-TNF). The acute responses of insulin sensitivity after an acute session of exercise will be assessed by the hyperinsulinemic euglycemic clamp, and the molecular pathways will be assessed by muscle biopsy and gene and protein expression analysis. Positron emission tomography-magnetic resonance imaging (PET/MRI) will be performed to quantify skeletal muscle glucose uptake.
This Phase 3 study will assess the safety and efficacy of a single dose of inclacumab, a P-selectin inhibitor, for a vaso-occlusive crisis (VOC) after an index VOC in participants with sickle cell disease (SCD). Participants will be randomized to receive either inclacumab or placebo.
