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 study (the SAVANNAH study) will investigate the efficacy of osimertinib in combination with savolitinib in patients with EGFRm+ and MET+, locally advanced or metastatic NSCLC who have progressed following treatment with osimertinib
Erythema Nodosum Leprosum (ENL) is a painful, debilitating complication of leprosy. Patients often require high doses of corticosteroids for prolonged periods. Thalidomide is expensive and not available in most countries. The use of corticosteroids for long periods is associated with adverse effects and mortality. It is a priority to identify alternative agents to treat ENL. Methotrexate (MTX) is a cheap, widely used medication which has been reported to be effective in ENL resistant to steroids and thalidomide.
The reason for this study is to see if the study drug baricitinib is safe and effective in the treatment of JIA in participants ages 1 to 17. This study is for participants that have been enrolled in studies I4V-MC-JAHV (NCT03773978) or I4V-MC-JAHU.
This is an open-label, multicenter, extension study. Patients who are receiving clinical benefit from atezolizumab monotherapy or atezolizumab in combination with other agent(s) or comparator agent(s) during participation in a Genentech or Roche-sponsored study (the parent study), who are eligible to continue treatment and who do not have access to the study treatment locally, may continue to receive study treatment in this extension study following roll-over from the parent study.
Molar-Incisive Hipomineralization (MIH) is defined as a qualitative change in tooth enamel of systemic origin, which affects one or more permanent first molars, and may or may not involve permanent incisors. MIH has several clinical repercussions, such as presence of hypersensitivity, difficulty in local anesthesia, reduction of restorations longevity, among others, making it difficult to perform dental treatment. Therefore, the present study will evaluate, through a randomized controlled clinical study, three restorative protocols for the treatment of severe MIH (with post eruptive enamel fracture and dentin exposure). The following groups will be evaluated: direct restoration with composite resin; restoration with composite resin with diode laser application and temporary restoration with glass ionomer cement followed by restoration with composite resin). The restorations will be evaluated after 1 week, 1, 6, 12, 18 and 24 months. The main outcome will be evaluation of restoration longevity, presence of caries lesion and wear of the restoration surface. Other outcomes such as patient satisfaction with treatment, patient discomfort, anxiety, assessment of dentin sensitivity and impact on participants' quality of life, as well as the duration and cost of treatment, as well as their cost-effectiveness ratio will also be evaluated . Multilevel statistical analyzes will be performed to verify the effectiveness of diode laser treatment compared to sealing, in addition to possible factors associated with this efficacy.
Cancer patients undergo many different modalities of treatments. Pharmacological treatment should be well understood. The nutritional status is not taken into account when calculating drug's doses and this may have an impact in toxicity and quality of life. The present study proposes to evaluate the relationship between the calculation of pharmacological treatment's doses, the toxicity and the impact on quality of life among colorectal and breast cancer's patients.
In vitro fertilization (IVF) techniques have been improving performance recently and, nowadays, provide a live birth rate of around 25%. The success of IVF techniques is dependent upon maximum efficiency at each stage of treatment, and, at the same time, high success rates with a low risk of complications. Multiple pregnancies are one of the most important adverse event of IVF techniques. In this sense, the use of elective single embryo transfer (SET) has become an option for patients with good prognosis compared to the transfer of multiple embryos, and it is recommended in order to reduce the risk of multiple pregnancies and their consequences. On the other hand, it is known that embryonic quality is a crucial step for the success of IVF techniques and the efficiency of this process is linked to the decrease in the number of embryos to be transferred. Usually, embryo selection is based on morphological and developmental criteria. However, recently, it has been demonstrated that the blastocyst biopsy associated with the chromosomal / genetic screening may be a predictor of the chances of implantation. The investigators group demonstrated the feasibility of performing SET sequentially, promoting satisfactory gestation rates and safety for the mother and baby regarding multiple gestation for patients with good prognosis. Based on these principles, the investigators raised the hypothesis that SET associated with preimplantation genetic diagnosis (PGD) by next-generation sequencing (NGS) for patients with good prognosis can improve the success rates of IVF cycles and, at the same time, avoid multiple pregnancies, as well as maternal-fetal and neonatal risks resulting from this condition. To test this hypothesis, the aim of this study is to compare the results of IVF treatments in patients receiving SET (SET group), SET associated with genetic evaluation by NGS (group NGS + SET), elective transference of two embryos (DET group) and DET associated with genetic evaluation by NGS (NGS + DET). In case of non-pregnancy on the first transfer, there will be subsequent transfers until the remaining embryos are exhausted or the patient reaches the gestation. The primary endpoint will be the cumulative pregnancy rate per treatment cycle and this approach will allow to confirm or not the hypothesis that genetic analysis is effective in improving the embryo selection process and associated with SET will increase clinical gestation rates and decrease rates of multiple gestations and miscarriages.
The long stay in mechanical ventilation can induce several complications, among them respiratory muscle weakness, this has been related to the duration of mechanical ventilation, delay and failure to wean, resulting in longer hospitalization, which reflects in greater care increase in hospital costs. Therefore, of this research will be to compare the effectiveness of early inspiratory muscle training (IMT) versus non-IMT in patients undergoing mechanical ventilation to improve the outcome of mechanical ventilation weaning time.
Obstructive sleep apnea (OSA) is a common clinical condition, involving the development of arterial hypertension. A Meta analysis study have shown that isometric hand grip training promotes blood pressure reduction. It is going to be conducted a clinical trail to determine the effects of hand grip training in OSA patients to change the arterial hypertension.
The research aims to verify the effects of the Mindfulness Based Health Promotion (PSBM) program on the quality of life of mothers of person with intellectual disability. Method: A randomized, controlled study with pre-post intervention measures and a follow-up measurement will be performed after six months of the end of the intervention. Sample: It will be composed of mothers of the 209 attended with moderate intellectual disability, adolescents and adults of the Service of Socioeducation of the Association of Parents and Friends of the Exceptional (APAE) of São Paulo, excluding those who have any psychiatric problem in the acute phase and minors, or who have regular practice of mindfulness or meditation in the last 6 months.
