There are about 5161 clinical studies being (or have been) conducted in Norway. 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.
The purpose of this study is to find out if nesiritide (a human B-type natriuretic peptide/hBNP) as compared to placebo, plus the usual treatment for acute decompensated heart failure, helps to improve breathing difficulties, reduce heart failure readmissions to hospitals, and helps patients live longer.
This trial is conducted in Africa, Europe, North and South America and Oceania. The aim of this trial is to compare the effect and safety on blood glucose control in pregnant women with type 1 diabetes of a modern insulin analogue (insulin detemir) and human insulin (NPH insulin) given as long-acting insulin in combination with a short-acting insulin (insulin aspart).
Joint replacement is a well-documented and cost effective treatment of degenerative diseases in the hip (1,2). There are two different principles of fixation of prosthesis components; cemented and uncemented. The most common mode of fixation in Scandinavia has historically been with bone cement. In the recent years a reverse hybrid combination (uncemented stem and cemented cup) is gaining popularity, especially in Norway. Beside luxation, infection and venous thromboembolism, the problem with aseptic loosening is a known complication. A marker for aseptic loosening is local bone loss around the components. This is measured with a densiometer and the method is Dual Energy X-ray Absorbtiometry (DXA). Periprosthetic bone loss is evaluated by series of DXA scans around the components over time. This enables us to follow changes in bone mineral density (BMD) close to the prosthesis. We want to compare cemented and uncemented prostheses with this technique. This is a problem since we don’t know how much different contrast medias in bone cement affect DXA scans. This area is poorly investigated. Attempts have been made to exclude the cement-mantle from the measurements both digitally and manually, but these have showed poor precision. A kind of consensus of assuming that contrast medias in bone cement give an increase in measured BMD of 20% (4). This is used when comparing cemented and uncemented components. We have preformed laboratory tests of different cements. Zirconium oxide (ZrO2) and Barium sulphate (BaSO4) are used as radiopacifiers. These contrast medias have different properties. Our test showed that Zirconium give 63% higher BMD when we scanned cement alone. This is supported by a cadaver study showing significant differences between contrast free cement and ZrO2 /BaSO4 containing cements. It is our opinion that it is necessary to perform a prospective study to investigate this more thoroughly. The hypothesis of this study is that it is not accurate enough to add 20% in BMD for cemented implants when comparing them with uncemented implants. It is probably necessary to take into account the amount of cement used and kind of contrast medium.
The purpose of the current trial is to explore whether the standard treatment with radiotherapy and temozolomide affect the tumor vasculature in patients with high-grade astrocytomas. If vascular effects are identified, future clinical trials can be proposed wherein anti-angiogenic agents are added to increase patient survival.
Patients on immunosuppressive therapy, e.g. organ recipients, have a higher occurrence of AK than the untreated population. Keratotic lesions (i.e. AK lesions and warts) in this population is highly associated with development of SCC also with 10 times higher mortality rate because of SCC than expected. The risk of developing skin cancer, predominantly SCC and BCC, increases with graft survival time and the length of immunosuppressive treatment period. The higher risk of developing skin malignancy and more aggressive skin malignancies in this population, indicate the need for early removal of these pre-malignant lesions. In this study, two contralateral areas (5x10 cm2) with skin lesions within the patient will be compared. One area will receive Metvix PDT at defined intervals and the other will receive lesion specific treatment at the discretion of the investigator. The primary end-point will be the accumulated number of new lesions during the study and number of AK lesions that show complete response 3 months after baseline. Secondary endpoints will be number of BCC lesions that show complete response, number of recurrent lesions, assessment of cosmetic outcome and safety.
In this study, the efficacy and safety of two nilotinib doses, 300 mg twice daily and 400 mg twice daily, were compared with imatinib 400 mg once daily in newly diagnosed patients with Philadelphia chromosome-positive (Ph+) Chronic Myelogenous Leukemia in the chronic phase (CML-CP). An extension protocol was included in this study design to allow patients who did not show sufficient response to their assigned treatments the opportunity to receive imatinib 400 mg BID (option available until protocol amendment 7) or nilotinib 400 mg BID, using an abbreviated safety and efficacy assessment schedule.
This is a 12 month study designed to evaluate the safety and effectiveness of SB-751689 in the treatment of osteoporosis in post-menopausal women, in comparison with 2 active comparators and placebo.
At our hospital, all Colles' fractures deemed suitable for conservative treatment are reduced and immobilised with a plaster of Paris dorsal splint which is converted to a complete cast after 10 days. According to individual factors such as age, general health and radiological results after 10 days, some patients with severe redisplacement are readmitted to hospital for surgery. The main purpose of this study is to determine whether, during the first 10 days of immobilisation, a complete plaster cast or a dorsal plaster splint best retains the alignment of a reduced Colles' fracture. In addition, we aim to compare the complication rates of the two methods.
The Efector study is an open, randomized and controlled trial assessing the effect of regular exercise training on endothelial function, inflammatory markers, progression of disease, heart rate variability and mental health in patients who have been successfully treated with percutaneous coronary intervention and stent implantation for angina pectoris.
Cardiopulmonary bypass(CPB) is associated with increased fluid extravasation and edema formation. A continuous infusion of a mixture of hypertonic saline/hydroxyethyl starch (HSH)during CPB reduced fluid extravasation and total fluid gain during bypass in an animal model. We hypothesize that a continuous infusion of HSH will reduce fluid load and increase hemodynamic and respiratory functions in patients undergoing coronary artery bypass with CPB.
