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.
In the present study the investigators aim to determine the efficacy of an immunomodulating topical medication, compared with a topical lubricant, on the treatment of dry eye disease (DED) due to primary or secondary Sjögren's syndrome (aqueous deficient DED) and evaporative DED.
The purpose of this study is to assess the safety and efficacy of enzalutamide in patients with non metastatic prostate cancer.
Breast neoplasm is the second most common type in the world. Radiation therapy is a key component in the treatment of breast cancer. Acute skin reaction is one of the most common side effects of radiation therapy. Several studies were performed for prophylaxis of this adverse event, however, until this moment there is no consensus for clinical practice . Second meta-analysis , the ideal candidate for the radiodermatitis prevention would be an agent capable of repairing damage to DNA or agents that promote cell proliferation . The low power laser promotes tissue repair ( reduces inflammatory phase and induces collagen synthesis ) . Its use in the treatment of adverse events of cancer treatment is well established in two situations : in the prophylaxis and treatment of mucositis and in the treatment of lymphedema . The purpose of this study is to use the low power laser in patients with breast cancer undergoing radiotherapy treatment to evaluate the effects of Laser InGaAIP 660Nm in preventing radiodermatitis.
A study to research the post-operative results according to the chosen surgical technique and evaluate the refractive changes before and after the excision of pterygium.
The purpose of this study is to evaluate the pharmacokinetics (blood levels) and pharmacodynamics (the action or effects a drug has on the body) of canagliflozin in children and adolescents with type 2 diabetes mellitus aged 10 to 17 years (inclusive). Other purposes are to investigate safety and assess the ease of swallowing the tablets.
Grave's ophthalmopathy is the most common cause of orbital disease in adults. The clinical presentation may vary between sub clinic symptoms to severe ones. The eyelid retraction is one of the most important signs of Grave's ophthalmopathy and can lead to cosmetic and functional problems. The eyelid retraction can be found in the inflammatory stage and in the chronic disease, when it is stable. It can be described when the upper lid is contouring the superior limbus or positioned above that. This condition can lead to dry eye symptoms, exposure keratitis and cosmetic issues. The treatment can may be surgical or medical. The medical treatment are usually based on controlling thyroid function and in the use of steroids, both are not specific for the lid retraction, but for the inflammation that is common in the disease. In the longstanding disease, surgery is the most efficient treatment. There are several described techniques, they are based on the concept of weakening the muscles that act on lid elevation (levator and Muller Muscle). Basically the techniques can be divided in two groups: the first with an anterior approach (with skin scar in the lid sulcus) and the second using a posterior approach (through the conjunctiva). In the literature there is no consensus in deciding the best technique, regarding cosmetic results, incidence of complications, hypo or hypercorrection. In this trial we propose to compare two distinct techniques that are already in clinical use. The blepharotomy uses a cutaneous approach and the other a conjunctival approach. The patients will be divided in two randomized groups and surgical expected outcomes, cosmetics outcomes and complications occurrence will be compared.
This open-label, randomized, 3-arm study will evaluate the efficacy and safety of obinutuzumab (RO5072759) in combination with chlorambucil as compared to rituximab plus chlorambucil or chlorambucil alone in patients with previously untreated chronic lymphocytic leukemia (CLL). Patients will be randomized 2:2:1 to receive a maximum of six 28-day cycles of either RO5072759 (1000mg iv infusion, on days 1, 8 and 15 of cycle 1 and day 1 of cycles 2-6) plus chlorambucil (0.5 mg/kg orally, days 1 and 15 of cycles 1-6), or rituximab (iv infusion day 1, 375 mg/m^2 cycle 1, 500 mg/m^2 cycles 2-6) plus chlorambucil, or chlorambucil alone. Anticipated time on study treatment is >6 months and follow-up for disease-progression and safety will be at least 5 years. In the US, this trial is sponsored/managed by Genentech.
The specific objective of this study is: - Evaluate and quantify colorimetric changes in young permanent anterior teeth; - Compare the efficiency and efficacy of three gels used for self-administered home whitening and an over the counter whitening strip; - Analyze the increase in dental sensitivity in adolescent patients submitted to home whitening with 6% and 7.5% hydrogen peroxide with and without the addition of calcium (whitening strips); - Assess sensitivity, comfort and acceptance of whitening strips by patients; - Assess patient satisfaction with the method and material used for home whitening.
The purpose of this study is to determine if eculizumab is safe and effective for the treatment of refractory generalized Myasthenia Gravis.
The study represents the research component of a broader initiative entitled "RedeAmericas". RedeAmericas (RA) is a collaborative effort of investigators from six cities across Latin America (Buenos Aires, Cordoba, Medellin, Neuquen, Rio de Janeiro, and Santiago) and Columbia University in New York. This is a pilot Randomized Controlled Trial (RCT) of Critical Time Intervention—Task Shifting (CTI-TS). It is designed to address a fundamental gap in the services offered by mental health clinics. These clinics are the primary locale for outpatient treatment of individuals with severe mental disorders in the urban areas of Latin America, and they offer some basic and important clinical care such as pharmacologic treatment onsite. Generally these clinics also have a major limitation; they have inadequate resources and training for the provision of in vivo community-based services, that is, services delivered outside of the clinic facility in homes or elsewhere in the community. In most urban areas, they also have weak links to primary health care and are not easily accessible to much of the population. CTI-TS, is a task shifting intervention that at the service user level provides support for better community living and promotes social integration, and at the system level strengthens the connections between mental health and primary care clinics. CTI-TS is a time-limited 9-month intervention provided at the critical time when a person is first offered services at a mental health clinic. During this period CTI-TS workers forge relationships that will shape the continuing use of services and enhance the potential for recovery over the subsequent course of time. The overall goal of CTI-TS is to improve the lives of those with severe mental disorders who receive community-based mental health care.
