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.
Comparison of the effects of CYT107 vs Placebo administered by intra-muscular route (IM) at 10μg/kg twice a week for three weeks on immune reconstitution of lymphopenic COVID-19 patients
Efficacy and safety of ofatumumab and siponimod compared to fingolimod in pediatric patients with multiple sclerosis
The goal of this clinical study is to test how well the study drug, lenacapavir (LEN), works in preventing the risk of HIV.
Although prone position is widely used in awake patients with COVID-19 associated with supplemental oxygenation, high flow nasal catheter, or noninvasive ventilation, few studies are attesting to its real benefits on physiological variables or intubation rate. Awake patients dependent on supplemental oxygen may have different responses to PP about peripheral oxygen saturation, heart rate, and respiratory rate. Such responses may be permanent, transient, or even absent. We believe that the response to PP can be a predictor of the need for admission to the ICU. This study aimed to evaluate the acute effects of different types of response to the prone position in patients awake with COVID-19.
A global study to demonstrate the effectiveness of selumetinib in participants with NF1 who have symptomatic, inoperable plexiform neurofibromas.
The purpose of this study is to compare the efficacy of Bortezomib, Lenalidomide and Dexamethasone (VRd) induction followed by a single administration of ciltacabtagene autoleucel (cilta-cel) versus VRd induction followed by Lenalidomide and Dexamethasone (Rd) maintenance in newly diagnosed multiple myeloma participants for whom ASCT is not planned as initial therapy in terms of Progression Free Survival (PFS).
Excessive gingival exposure, commonly named gingival smile, results in a dentogingival disharmony. One of the gingival smile treatment is the aesthetics-related crown lengthening surgery (ACL) to provide a adequate clinical crown length and diminish gingival display. In this context, digital planning and guided dual technique have been proposed to increase the effectiveness and predictability of the ACL. In this technique, an facial and dental analysis of the patient is performed and transferred to a digital model obtained by intraoral digital scan. The digital model is used to create a double guide that will determine the final position of the gingival and alveolar margin in the ACL. Despite the technique showing promising results, clinical studies evaluating the effectiveness of this technique are scarce. The present study aims to evaluate the digital planning and guided dual technique in the ACL in comparison to conventional technique in relation to the predictability/stability of the gingival margin positioning and patient satisfaction after the ACL. Twenty-four patients diagnosed with altered passive eruption type I subcategory B will be selected and divided into two groups. In the control group (n = 12) patients will be submitted to the conventional ACL planned using clinical examination; in the test group (n = 12) patients will be submitted to ACL using cone beam computed tomography (CBCT), digital planning and guided dual technique. Periodontal clinical parameters including probing depth (PS), clinical attachment level (CAL), clinical crown length (CCL), anatomical crown length (ACL) and cemento-enamel junction to alveolar bone crest distance will be evaluated clinically at baseline, in the immediate postoperative, 4, 8 and 12 months after the procedure. Participants will be submitted to questionnaires to assess satisfaction with the smile, gum and tooth characteristics and experience with the procedure. The investigators aim to demonstrate with the study the effectiveness of the both techniques and evaluate the clinical cost benefit for the patient and the dentist of the guided dual technique in relation to the conventional ACL technique.
The administration of acetylcholinesterase inhibiting agents (such as neostigmine) has been used to reverse the muscle paralysis induced by non-depolarizing neuromuscular blocking agents. It is not well known whether there is a difference between the time required for complete reversion of moderate neuromuscular blockade (NMB) after the administration of neostigmine in usual doses when compared to the reversion of superficial NMB with the use of a reduced dose of the same agent (excessive doses of neostigmine administered during superficial blocks may cause paradoxical muscle weakness). The aim of the present study will be to compare, by means of a prospective, randomized, controlled and double-blind clinical trial, the times necessary for the reversion of moderate block with neostigmine 60 mcg / kg or for superficial block to reach values of T4 / T1> 0.9 using neostigmine 30 mcg / kg.
This research was carried out with the objective of verifying the possibility of intervention through cognitive training protocols to assist in the stimulation of neurons and to delay the degradation resulting from Alzheimer's disease in its initial phase. The specific objective of this research was to develop and validate a virtual environment of games (called SorrisoTur) that allows the intervention of cognitive training.
This study will assess the efficacy and safety of Niraparib in participants with either tumor mutation in the BRCA gene (tBRCAmut) HER2- breast cancer (Independent of hormone receptor [HR] status, including HR positive [+] and TNBC) or tumor BRCA wild type (tBRCAwt) TNBC with molecular disease based on the presence of circulating tumor Deoxyribonucleic acid (ctDNA) following surgery or completion of adjuvant therapy.
