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.
This work aims to assess cardiopulmonary function and quality of life in people with sequelae of pulmonary tuberculosis undergoing rehabilitation. It is an experimental clinical study, with evaluation before and after the intervention. Included participants will be randomized and divided into a control group and an intervention group. Quality of life is examined by two questionnaires and physical fitness by specific tests, before and after the intervention. The intervention is the realization of a supervised physical exercise protocol.
This is a phase I, double-blind, placebo-controlled,dose-ranging clinical trial in healthy males and non-pregnant females, 18 to 55 years of age. The trial is designed to assess the safety, reactogenicity, and immunogenicity of VACCINE RNA MCTI CIMATEC HDT(HDT-301), which is a novel Lipid-Inorganic Nanoparticle (LION) formulated replicating RNA-based vaccine that encodes for a full-length spike (S) protein of the SARS-CoV-2 virus. As a replicating mRNA vaccine, VACCINE RNA MCTI CIMATEC HDT(HDT-301) has the potential to allow the advantages of dose sparing, and possibly administration as a single dose, compared with other mRNA platforms. Enrollment will occur at one domestic site. A total of 90 healthy subjects will receive multiple dosages of intramuscular (IM) injections of VACCINE RNA MCTI CIMATEC HDT(HDT-301). Participants will be enrolled sequentially in three dose cohorts (cohort 1 = 1 µg, cohort 2 = 5 µg, and cohort 3 = 25 µg), with each cohort consisting of a total of 30 subjects. Within each dose cohort, participants will be randomized (4:1 ratio for active vaccine:placebo) with equal probability of receiving a schedule of two doses, of the same concentration, on days 1 and 28 (group 1) or 1 and 56 (group 2), or a schedule of single dose administration (group 3) VACCINE RNA MCTI CIMATEC HDT(HDT-301). The main objective is to evaluate the safety and reactogenicity of 3 dose vaccination schedule of VACCINE RNA MCTI CIMATEC HDT(HDT-301) and 1 dose of placebo in healthy adults. Safety and tolerability will be the primary endpoint assessed by incidence of adverse events for each dose through 12 months after the vaccination. Scheduled interim immunogenicity evaluations will be conducted for pre-specified timepoints as secundary and exploratory endpoints.
Major depressive disorder (MDD) is a common psychiatric condition, mostly treated with antidepressant drugs, which are limited for issues such as refractoriness, adverse effects and drug interactions, especially in the elderly population. In this context, the investigators investigate a non-pharmacological treatment known as recurrent transcranial magnetic stimulation (rTMS) with the theta-burst stimulation (TBS) method for the treatment of geriatric depression. This treatment modality has almost no adverse effects and avoids the risk associated with polypharmacy, providing an interesting alternative to antidepressant treatments. Our aim is to evaluate TBS efficacy in the treatment of geriatric depression in a randomized, double-blind, placebo-controlled clinical trial.
To demonstrate the efficacy of VERU-111 in the treatment of SARS-Cov-2 Infection by assessing its effect on the proportion of patients who die on study (prior to Day 60).
The goal of this randomized controlled trial is to investigate the effects of a dance intervention performed at home, on cardiovascular risk factors and functional capacity of elderly individuals with and without type 2 diabetes mellitus. Comparison will be performed with a walking exercise intervention, performed outside. Dance sessions will be guided online by an expertise instructor, and walking sessions will be performed at a self-selected intensity, with no simultaneous supervision. All participants will complete an exercise diary after each exercise session (reporting perception of subjective effort, affective responses, and others).The participants will include men and women between 65 and 80 years old, with body mass index inferior to 35 Kg /m2. The main outcome of this study is the peak oxygen consumption (VO2peak). The secondary outcomes are cardiovascular risk associated factors (C-reactive protein, TNF-alpha, lipid profile, etc) and functional performance (muscle strength and power, balance, gate ability, etc). Cognitive skills (executive function and memory) will be also assessed. The experimental design will include a control period of four weeks, two sessions of assessments before and after the interventions, and twelve weeks of dancing or walking interventions, performed three times a week, in non-consecutive days, with 60 min duration.
A randomized, placebo-controlled study designed to evaluate the safety and efficacy of paltusotine (also known as CRN00808; an orally administered nonpeptide somatostatin agonist) in subjects with acromegaly previously treated with somatostatin receptor ligand (SRL) based treatment regimens.
The use of polyclonal anti-T cell antibodies (ATG) has benefits in kidney transplantation, however, its use is associated mainly with hematological, infectious, and neoplastic complications. Monitoring T cells in patients receiving ATG was first proposed in 1975 to improve efficacy in preventing acute rejection and avoiding excessive immunosuppression. The dose regimen is guided by a daily count of TCD3+ lymphocytes. Monitoring the dose of thymoglobulin through its biological effects on T cells is a rational and safe method of titrating the dose of that antibody. This way, it is possible to reduce the total amount of drug administered to the patient and, consequently, reduce undesirable complications, as well as the cost of treatment, without losing effect on the benefit of immunosuppression. Currently, the usual cumulative dose of ATG for induction in kidney transplant patients is 6mg/kg, in divided doses. However, the ideal dose and duration of therapy are still the subject of studies, with protocols between centers varying from total doses of 3 to 6 mg/kg, either fractionated or single, to achieve the lowest dose with fewer undesirable effects, and with reduced length of inpatient stay. The use of ATG in a single dose of 3 mg/kg was successfully assessed for risks of infection and rejection in patients with low immunological risk. This study proposes evaluating the efficacy and safety of a single 3mg/kg dose of ATG for patients with low and standard immune risk, with TCD3+ lymphocyte monitoring, to assess the duration of the TCD3+ cells in the peripheral blood.
In hypertensive mothers, it is common in clinical practice to substitute methyldopa for another medication, such as captopril, immediately after delivery, which may, as a consequence, cause a rebound effect or an initial lack of blood pressure control until the new medication had a more complete action. Thus, the treatment of hypertension in the puerperium is generally guided by expert opinion and recommendations for guidelines, based on non-robust evidence. OBJECTIVE: To evaluate the control of blood pressure in postpartum women with hypertensive syndromes during pregnancy with the maintenance of the continued use of previously used methyldopa compared to switching from antihypertensive regimen to the use of captopril. METHOD: Randomized, double-blind, drug controlled clinical trial. EXPECTED RESULT: better pressure control with the continued use of methyldopa.
Breast cancer directly affects women physically, psychologically and socially in the process of diagnosis, treatment and post-treatment. Despite the improvement in conventional breast cancer treatments that led to longer disease-free survival, many patients still suffer from physical, psychological, social and spiritual problems after treatment. The neglect of physical and psychosocial problems faced by patients who are between 1 and 2 years after the end of treatment negatively impacts the quality of life of this population.
Phase I/II Randomized Clinical Trial to evaluate the safety, pharmacokinetic and efficacy of Anti-SARS-CoV-2 hyperimmune serum. The study will include patients at early stage of COVID-19 with increased risk for severe disease due to underlying medical conditions to determine the utility of an equine heterologous serum anti-SARS-CoV-2 to avoid progression to a severe COVID-19
