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.
The study aims to characterize prospectively longitudinal progression of neurological domains in GM1 and GM2 Gangliosidosis patients with high-quality standards (GCP compliant).
The aim of this study is to evaluate the effects of probiotic administration of L. paracasei 28.4 as an adjunct to the non-surgical periodontal treatment in patients with periodontitis.
The study will evaluate the safety and efficacy of datopotamab deruxtecan (also known as Dato-DXd, DS-1062a), when compared with Investigator's choice of standard of care single-agent chemotherapy (eribulin, capecitabine, vinorelbine, or gemcitabine) in participants with inoperable or metastatic HR-positive, HER2- negative breast cancer who have been treated with one or two prior lines of systemic chemotherapy.
The TODAY trial is a study to evaluate the efficacy and safety of topical oxybutynin deodorant for use in patients with axillary hyperhidrosis.
The purpose of this study is to compare treatment with olorofim versus treatment with AmBisome® followed by standard of care (SOC) in patients with IFD caused by proven IA or probable lower respiratory tract disease Aspergillus species (invasive aspergillosis, IA).
The purpose of the study is to compare the efficacy of zanubrutinib plus obinutuzumab versus lenalidomide plus rituximab (R^2) in participants with relapsed/refractory (R/R) follicular lymphoma (FL), as measured by progression-free survival as determined by an independent review committee in accordance with the 2014 modification of the International Working Group on non-Hodgkin lymphoma (NHL) Criteria based on n positron emission tomography and computed tomography (PET/CT), and to compare the efficacy of zanubrutinib plus rituximab versus R^2 in participants with R/R marginal zone lymphoma (MZL), as measured by progression free survival (PFS) assessed by IRC in accordance with CT-based Lugano 2014 Criteria.
This study aims to evaluate the effectiveness of ultrasonic irrigation in improving root canal disinfection after chemomechanical procedures.
155 Pérola Byington Hospital patients presenting early stage luminal BC were submitted to Oncotype Dx® evaluation. Changes in treatment recommendations and costs were obtained from Pérola Byington Hospital. Oncotype DX® incorporation in the Brazilian Public Health System should be considered, as it results in high clinical impact for patient and high economic impact for health system, being a tool that safely and accurately delimits the subgroup of patients who really need AC.
The main purpose of this trial is to evaluate the efficacy of PTC923 in reducing blood phenylalanine (Phe) levels in participants with phenylketonuria as measured by mean change in blood Phe levels from baseline to Weeks 5 and 6 (that is, the average of each respective treatment dose 2-week period of double-blind treatment).
Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC), a group of lung cancers that have spread to nearby tissues or to other parts of the body. Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) are proteins that help cells to grow and divide. A damage (also called mutation) to the building plans (genes) for these proteins in cancer cells leads to a production of abnormal EGFR and/or HER2. These abnormal proteins drive the growth and the spread of the cancer. Several EGFR and/or HER2 mutations exist in the cancer cells. The study treatment, BAY2927088, is expected to block the mutated EGFR and HER2 proteins which may stop the spread of NSCLC. The main purpose of this study is to learn: Escalation, Backfill, and Expansion Part: - How safe is BAY2927088 for the participants? - What is the highest dose of BAY2927088 that can be tolerated (maximum tolerated dose) by or given to (maximum administered dose) the participants? - How does BAY2927088 move into, through, and out of the bodies of the participants? For this, the researchers will measure the followings: - The number of participants with medical problems, also called adverse events and serious adverse events, and their severity - The number of participants who discontinue study treatment due to an adverse event. - The highest dose of BAY2927088 that the participants can take without having adverse events (maximum tolerated dose (MTD)) or the maximum dose that is tested and found to be safe for the participants in case MTD cannot be found out (maximum administered dose (MAD)) of BAY2927088 - Number of participants experiencing adverse events that prevent an increase in the dose of BAY2927088 (dose-limiting toxicities (DLTs)) at each dose level - The (average) total level of BAY2927088 in the blood (also called AUC) after receiving single or multiple doses of BAY 2927088 - The (average) highest level of BAY 2927088 in the blood (also called Cmax) after receiving a single or multiple doses of BAY2927088 Extension Part - How well does BAY 2927088 work in participants? For this, the researchers will measure the following: • Percentage of participants whose cancer completely disappears (complete response) or reduces by at least 30% (partial response) after taking the treatment (also known as objective response rate (ORR)). This will be assessed by doctors other than the study doctor. This study has 4 parts: - The escalation part aims to find the maximum daily amount (dose) of BAY2927088 that participants can receive. - The backfill part aims to test the doses of BAY2927088 that are considered safe in the escalation part by giving it to more participants. This will help find optimal doses of BAY 2927088 that work well and are safe to be tested in the next part. - The expansion part aims to determine the dose of BAY2927088 to be tested in further studies. - The extension part aims to determine whether the selected dose of BAY2927088 from the expansion part works well. The participants in this study will take the study treatment BAY2927088 in 3-week periods called "cycles". They will in general take BAY2927088 once or twice daily as a liquid/tablet by mouth until their cancer gets worse, they have medical problems, they leave the study, or the study is terminated. Participants will have no more than 5 visits per cycle. During the study, the study team will: - take blood and urine samples, - check the status of the cancer by doing computed tomography (CT) or magnetic resonance imaging (MRI) scans, - check the participants' overall health and heart health, - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is considered "serious" when it leads to death, puts the participant's life at risk, requires hospitalization, causes disability, causes a baby being born with medical problems, or is medically important.
