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 is a multicenter, open-label, extension study to evaluate the long-term safety, tolerability, and efficacy of treatment with AG-348 in participants who were previously enrolled in Study AG348-C-006 or Study AG348-C-007.
Primary Objective: To explore associations between biomarkers of atopic dermatitis (AD) and: - Disease state and time course of AD, - Disease state and evolution of selected atopic comorbid conditions, - Effectiveness of specific AD treatments.
A global study to assess the efficacy and safety of durvalumab in combination with bevacizumab or durvalumab alone in patients with hepatocellular carcinoma who are at high risk of recurrence.
The purpose of this study is to evaluate the efficacy and safety of acalabrutinib in combination with venetoclax and acalabrutinib in combination with venetoclax with and without obinutuzumab compared to chemoimmunotherapy in subjects with previously untreated CLL
The objective of this double-blind randomized clinical trial is to evaluate the influence of caries risk, occlusal stress and missing teeth on anterior restorations over a 10 years follow up period. 300 teeth will be randomized according to two adhesive systems: Single Bond 2 and Single Bond Universal (3M ESPE); and two composite resins: nanoparticulated (Filtek ™ Z-350- 3M ESPE) and nanohybrid (IPS Empress Direct - Ivoclar Vivadent). The randomization will be stratified according to the risk of caries and cavity type. The primary outcomes will be longevity, annual failure rate (AFR) and the success of the restorations, and the secondary outcome will be causes for restorations' failure.
The purpose of this study is to assess the efficacy and safety of the combination of pembrolizumab (MK-3475) and enzalutamide in the treatment of men with metastatic castration-resistant prostate cancer (mCRPC) who have not received chemotherapy for mCRPC, are abiraterone-naïve, or are intolerant to or progressed on abiraterone acetate. There are two primary study hypotheses. Hypothesis 1: The combination of pembrolizumab plus enzalutamide is superior to placebo plus enzalutamide with respect to Overall Survival (OS). Hypothesis 2: The combination of pembrolizumab plus enzalutamide is superior to placebo plus enzalutamide with respect to Radiographic Progression-free Survival (rPFS) per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as assessed by blinded independent central review.
Cutaneous squamous cell carcinoma (cSCC) is one of the most frequent malignancies worldwide, and an increasing incidence has been documented over the past decades. Despite optimal initial approach, which can be curative in the majority of cases, a proportion of patients present with locally advanced or unresectable disease, leading to significant morbidity. In addition, metastases of cSCC may affect 2 to 5% of individuals diagnosed with this disease. In the setting of advanced cSCC, no standard systemic treatment has been established, and treatment options are frequently adapted from those applied to squamous cell carcinoma arising from other sites, based on a low level of evidence and often with short-lived benefits. cSCC are potentially immunogenic neoplasms with an unmet need for therapeutic options, having sun exposure and chronic inflammation as the most significant risk factors. Using the anti-PD1 monoclonal antibody nivolumab to treat patients with cSCC and planned scientific correlates, investigators believe that the safety and efficacy of immune activating therapy for this disease can be assessed. This is a multi-center, Simon two-stage, phase II study to evaluate the safety and efficacy of the anti-PD1 monoclonal antibody nivolumab for systemic-treatment-naïve patients with metastatic and/or locally advanced cSCC. The primary objective of the study is to evaluate the efficacy, as assessed by the best objective response rate (complete response + partial response) at 24 weeks according to RECIST criteria, of nivolumab in patients with advanced cSCC. Secondary objectives are to assess the safety/tolerability of the treatment, to determine the progression-free survival (PFS) and overall survival (OS) rates at 24 weeks, and to evaluate the objective response rate as assessed by immune-related response criteria (irRC). Treatment will be given every 14 days until disease progression, unacceptable toxicity or withdrawal of consent/patient decision. If the patient continues to benefit from treatment with nivolumab, treatment will be continued for up to 12 months. Patients will be reassessed at week 12 and every 12 weeks thereafter until week 52, and then as per discretion of the treating investigator. A tumor biopsy will be performed before treatment initiation, unless contraindicated and optional biopsies will be performed at week 13 and following disease progression. Serial blood samples will be obtained at baseline, during, and after treatment.
This is a randomized, double-blind, study that compares pembrolizumab (MK-3475) with placebo given as adjuvant therapy in participants with high-risk locally advanced cutaneous squamous cell carcinoma (LA cSCC) that have undergone surgery with curative intent in combination with radiotherapy. The primary hypothesis is that pembrolizumab is superior to placebo in increasing recurrence free survival (RFS).
QT interval prolongation and neutropenia are considered to be important identified risks for ribociclib. The approved dosing regimen of ribociclib is 600 mg daily (QD) on a 3 weeks on/1 week off schedule. The purpose of the study is to explore whether a reduced dosing regimen of 400 mg ribociclib orally QD 3 weeks on/1 week off may decrease the risk of QTc prolongation without compromising the efficacy of ribociclib in combination with a non-steroidal aromatase inhibitor (NSAI) in pre- and postmenopausal women with hormone receptor-positive (HR-positive), HER2-negative advanced breast cancer (aBC) who have not received prior therapy for advanced disease.
The purpose of this study is to assess the safety and efficacy of pembrolizumab (MK-3475) combined with lenvatinib (MK-7902/E7080) compared to pembrolizumab alone (with placebo for lenvatinib) as first-line treatment in adults with no prior systemic therapy for their advanced melanoma. The primary study hypotheses are that: 1) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1), and 2) The combination of pembrolizumab and lenvatinib is superior to pembrolizumab and placebo as assessed by Overall Survival (OS). For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ.
