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, double-blind, Phase 2b, long-term extension (LTE) to the ADDRESS II core trial (EMR 700461-023) (NCT01972568), to evaluate long-term safety and tolerability of atacicept in participants with systemic lupus erythematosus (SLE). Participants who completed the 24-week core study ADDRESS II core study (NCT01972568) and thus not met any of the discontinuation criteria were invited to enter this long-term extension (LTE) study NCT02070978.
With the possibility of pathological complete response in surgical specimens, some authors have proposed non-operative management of the patient group, when re-staged after neoadjuvant treatment, have complete clinical response. So far, this approach remains discussed in the literature, and there are still many uncertainties that patients with clinical complete response after chemoradiotherapy in fact no detectable viable tumor and may be omitted of radical surgical treatment. It is a still investigational approach and actually gained space even for patients with very high or who refuse surgery after all clarifications surgical risk. Hypothesis: The preservation of the rectum in patients with adenocarcinoma of the middle and distal rectum (up to 10 cm) reaching clinical complete response after neoadjuvant chemoradiotherapy have similar rate of the rectal cancer recurrence than patients who underwent surgical rectal resection. This will be a prospective, randomized, open label phase II of surgical resection versus conservative treatment (observation) in patients with mid and distal rectal cancer who achieved complete after neoadjuvant chemoradiotherapy combined with clinical response. The main objective of this study is to assess whether conservative approach is similar to rectosigmoidectomy with complete mesorectal excision or amputation abdminoperineal the rectum in patients with complete clinical response after neoadjuvant therapy combined chemoradiotherapy. Patient Selection: To be eligible patients who have neoadjuvant prior histologic diagnosis of rectal adenocarcinoma, tumors located within 10 cm from the anal verge, a complete clinical response after treatment with chemoradiotherapy for rectal tumors staged clinical and radiological T3-4 N0 M0 or T (any) N + M0, absence of colorectal synchronous tumors. Treatment: Eligible patients will be randomized 1:1 to resection of the rectum or notice. The period for randomization of patients will be 12 weeks after the last dose of radiotherapy / chemotherapy, so that we can properly assess the antitumor response as described above. After randomization, patients in the surgical group will undergo resection of the rectum with complete excision of mesorectal within 2 weeks after randomization.
Acute viral bronchiolitis is an extremely common childhood disease, responsible for approximately 17% of childhood admissions to hospital per year, with an annually cost that reaches U$ 500 million. Despite being a well known disease among pediatricians, there are few, if any, effective treatment options apart from oxygen supplementation and adequate hydration. The purpose of this study is to determine wether nebulized hypertonic saline (3%) is more effective than normal saline (0,9%) when used in repeated doses during the first 24 hours of in-hospital treatment.
This research is being done so that we can look at the safety and efficacy of deferiprone in people with sickle cell disease or other anemias. Deferiprone is a drug that removes iron from the body. We will be comparing deferiprone with deferoxamine, another drug that removes iron from the body.
This study is design to evaluate the influence of oxytocin in some aspects of Autism Spectrum Disorder (ASD), such as, repetitive and stereotyped behavior, social skills, quality of life and disruptive behaviors. Null hypothesis: social skills, quality of life, disruptive behaviors and repetitive behaviors do not improve with the use of oxytocin. Experimental Hypothesis: social skills, quality of life, disruptive behaviors and repetitive and stereotyped behaviors improve with the use of oxytocin.
The purpose of this study is to collect patient related benefit data following treatment for permanent hearing loss with a hearing implant from the company Cochlear over a period of 2 years post treatment. Assessment of benefits is based on standard questionnaires of hearing ability and quality of life in general.
This study evaluates the PCSK9 inhibitor, Bococizumab (PF-04950615;RN316), compared to placebo, in reducing the occurrrence of major cardiovascular events, including cardiovascular death, myocardial infarction, stroke, and unstable angina requiring urgent revascularization in high risk subjects who are receiving background lipid lowering therapy and have cholesterol laboratory values of LDL-C >/= 100 mg/dL (2.6 mmol/L) or non-HDL-C >/=130 mg/dL (3.4 mmol/L).
This study evaluates the PCSK9 inhibitor, Bococizumab (PF-04950615;RN316), compared to placebo, in reducing the occurrence of major cardiovascular events, including cardiovascular death, myocardial infarction, stroke, and unstable angina requiring urgent revascularization, in high risk subjects who are receiving background lipid lowering therapy and have cholesterol laboratory values of LDL-C >/= 70 mg/dL (1.8 mmol/L) or non-HDL-C >/= 100 mg /dL (2.6 mmol/L).
The purpose of this study is evaluate the natural course of disease progression related to gross motor function in children with metachromatic leukodystrophy (MLD).
The purpose of this study is to evaluate the therapeutic response to fluconazole in patients with cutaneous leishmaniasis caused by and L.(V.)guyanensis and L.(V.) braziliensis.
