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 aims to investigate the use of amlodipine, a drug that blocks the uptake of calcium into cells, in the prevention and treatment of iron overload in patients with thalassemia major. Since iron uses the same calcium channels to enter the heart, pancreas and other organs, blocking these channels might help to prevent the accumulation of iron in these tissues. The study will follow 60 patients with thalassemia major: 30 will receive amlodipine and 30 will serve as controls receiving placebo in a randomized double-blind fashion. Patients will be monitored through one year. Monitoring will occur through the measurement of blood ferritin as well as live and heart T2* by MRI initially, at 6 and 12 months.
The purpose of this trial is to assess whether dulaglutide can reduce major cardiovascular events and other serious outcomes in persons with type 2 diabetes, when added to their anti-hyperglycemic regimen.
This is a multicenter clinical trial, phase III, non-inferiority, controlled by active medicine, open, randomized, enroll 538 children, 2 to 12 years old, with acute inflammation upper airway, characterized by nasal congestion and runny nose, lasting at least 24 hours and a maximum of 48 hours prior to inclusion. The subjects will be allocated in 2 parallel groups, and will receive the medicines of study, according of the randomization.
Sildenafil citrate slightly reduces blood pressure in treated hypertensives patients. However, it is unknown if the simultaneous use of sildenafil plus, at least, 3 classes of antihypertensive agents in patients with resistant arterial hypertension may have a synergic effect on the patients blood pressure. Moreover, sildenafil improves the endogen nitric oxide effects. The nitric oxide is an important signaling molecule in the body that contributes to vessel homeostasis by inhibiting vascular smooth muscle contraction and growth. Hypertension often impaired NO pathways. Nitric oxide is produced by an enzyme, called nitric oxide synthase (NOS3), that show some genetics variants, which means that this enzyme can be different from person to person. Therefore, the objective of the present study is to examine the influence of a genetic variant (known to affect NOS3 levels) in sildenafil acute effects on hemodynamic and cardiovascular function. The investigators hypothesis is that individuals with the genetic variant associated to higher levels of NOS3 will have more benefits from sildenafil treatment.
This trial is conducted globally. The purpose of this trial is to confirm the efficacy and safety of NNC 0078-0000-0007 in patients with congenital haemophilia and inhibitors.
This study will assess the efficacy and safety of secukinumab in patients with active psoriatic arthritis who are intolerant to or have had an inadequate response to NSAIDs, DMARDs and / or TNFα inhibitor therapy.
The main side-effect of Implanon is the changes induces in bleeding patterns including amenorrhea, infrequent to irregular bleeding and frequent and prolonged bleeding; without any previous symptom and it was characterized as "breakthrough bleeding" (BTB). BTB is the main causes of early discontinuations. Unfortunately, there is no indication to predict prior to insertion what sort of bleeding pattern any individual woman may have after insertion and the proposed treatments were disappointed. Nevertheless, previous studies with other progestin-only contraceptives (including Implanon) provide evidence that the provision of adequate and intensive counseling to potential users and new acceptors about bleeding changes can help to improve method continuation. The availability of Implanon in the public sector could help in the development of strategies to introduce the method in the public sector network and the training of medical residents.
The objective of this research is to evaluate the effect of massage therapy as a resource for pain relief during the active phase of labor. The research will be of type randomized controlled trial, consisting of low-risk nulliparous pregnant women admitted to the Referral Center for Women's Health in Ribeirão Preto. The mothers will be distributed in two groups (lumbosacral massage) and control (routine maternity) and will be assessed before and after therapy, which corresponds to 30 minutes between 4-5 cm of cervical dilation. The evaluation will be performed by numerical category scale, Diagram Location of Pain and Pain Questionnaire McGll (reduced form). After delivery will apply a customer satisfaction questionnaire.
Prospective trial comparing post-operative complications and seroma formation after mastectomy in patients with breast cancer, using conventional electric scalpel and harmonic scalpel.
The aim of this study is to establish an active surveillance in order to generate dengue disease burden estimates including incidence rates, prevalence data, clinical presentation and cost of illness in Forteleza (Brazil).
