Filter by:This randomized phase I/II trial studies giving leuprolide acetate or goserelin acetate together with or without vismodegib followed by surgery to see how well they work in treating patients with prostate cancer that has spread from where it started to nearby tissue or lymph nodes. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as leuprolide acetate or goserelin acetate, may lessen the amount of androgens made by the body. Vismodegib may slow the growth of tumor cells. Giving antihormone therapy together with vismodegib may be an effective treatment for prostate cancer.
There has been an increase in ambulatory surgical procedures performed across Canada; ambulatory procedures account for almost 70% of all surgeries. Postoperative nausea and vomiting (PONV) and pain are the most frequently reported adverse events by patients prior to discharge after ambulatory surgery. The incidence can be as high as 70 to 80% in high-risk patients. PONV is a cause of morbidity particularly in gynecological procedures and the incidence of patients experiencing PONV is as high as 58-75%. Apart from delayed recovery, the occurrence of PONV has been linked to gastric aspiration, psychological distress and wound dehiscence. The occurrence of PONV delays patient discharge and further more is a leading cause of unexpected admission after ambulatory anesthesia Promethazine, is an antiemetic medication that has been widely used over the last 50 years, and although effective at reducing PONV, it tends to cause sedation. In this study, we are trying to determine if a smaller dose of promethazine, in addition to the standard treatment for post-surgical nausea and vomiting, will be more beneficial than the standard treatment on its own. It is hypothesized that the use of low dose promethazine (3 mg) as part of a multimodal antiemetic regimen will be efficacious in preventing PONV without the sedative effects of promethazine.
This phase I trial is studying the side effects and the best dose of entinostat when given together with sorafenib tosylate in treating patients with advanced or metastatic solid tumors or refractory or relapsed acute myeloid leukemia. Entinostat and sorafenib tosylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
RATIONALE: Low dose deferasirox may be safe and effective in treating patients who have undergone hematopoietic stem cell transplant and have iron overload. PURPOSE: This pilot clinical trial studies safety and tolerability of deferasirox in hematopoietic stem cell transplant recipients who have iron overload. Effect of low dose deferasirox on labile plasma iron is also examined.
Meropenem is an intravenous antibiotic commonly used to treat acute exacerbation of respiratory infections in cystic fibrosis. The research study aims to determine if a different method of infusing the drug over 3 hours or longer, instead of the traditional half-hour will improve target attainment of drug concentrations and bactericidal activity. A secondary aim is to assess if the pharmacokinetics of meropenem is different during active infection compared to non-infective stage. Twelve patients admitted with acute respiratory infection and who requires meropenem will be enrolled into the study. Meropenem blood concentrations collected over 8 hours will be measured after half-hour and 3-hour infusions on different days. A pharmacokinetic modelling and Monte Carlo simulation program will use the data to assess and predict the optimal method of dosing. When patients return for a follow-up clinic visit, a single dose of meropenem will be administered and blood concentrations will be measured to determine the pharmacokinetics during non-infective stage.
This study seeks to determine, using special sleep tests (polysomnography and actigraphy) if guanfacine extended release is able to improve nighttime sleep in children with ADHD - associated insomnia while improving daytime ADHD symptoms. Male and female children with diagnosed or suspected ADHD with sleep problems (difficulty falling asleep, difficulty staying asleep, or less than expected hours of sleep) will be recruited. After obtaining informed consent and assent (when appropriate) and after discontinuation of excluded medications, children will have evaluations of his or her sleep and evaluations confirming the ADHD diagnosis. Children who successfully pass screening will be enrolled into the double-blind, placebo-controlled, randomized investigation with 50% of participants receiving guanfacine extended release and 50% of participants receiving matching placebo. Using a flexible-dose optimization design based on ADHD symptom improvement and medication tolerability, the dose will be adjusted between 1 to 4 mg over the course of four weeks. At the end of medication adjustment (week 4 or 5), ADHD questionnaires, sleep questionnaires, and sleep tests will be repeated and analyzed. The medication will be weaned over the course of the following 3-10 days.
Selenium, in the form of inorganic Sodium Selenite, may be useful for treating existing prostate cancer. This idea is based on data from our laboratory showing that 1) prostate cancer cells are more sensitive to Selenium (Sodium Selenite)-induced apoptosis than normal prostate epithelial cells, 2) Selenite induces significant growth inhibition of well established prostate cancer tumors in mice at doses that have no detectable toxicity, and 3) Selenite disrupts AR signaling, and that the inhibition of AR expression and activity by Selenite occurs via a redox mechanism involving GSH, superoxide, and Sp1. Altogether, these findings suggest that Selenium may be useful in a variety of potential indications in the natural history of prostate cancer, including both hormone sensitive and castrate resistant prostate cancer, as a single agent, or in combination with radiation, chemotherapy or conventional hormone therapy. Selenite is a potential novel inhibitor of AR expression and function in prostate cancer.
Study evaluating the efficacy and safety of intravenous (IV) ferumoxytol compared with oral iron for the treatment of pediatric participants with chronic kidney disease (CKD).
Endoscopic closure of tracheoesophageal fistulas with a device used for closure of cardiac septal defects.
This is a prospective, open label randomized study. The purpose of this study is to compare propofol with dexmedetomidine for pediatric monitored anesthesia care for MRI, specifically identifying important patient demographics and looking at important outcomes including adverse events.
