There are about 8563 clinical studies being (or have been) conducted in Sweden. 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.
200 patients with insufficient great saphenous veins will be randomized to either radiofrequency ablation or high ligation/stripping (open surgery). They will be examined according to standardized examination protocol Venous Clinical Severity Score (VCSS), with duplex ultrasound and plethysmography pre- and postoperatively (1-month, 1-, 3 and 5 years). They are to fill questionnaires EuroQol 5 Dimensions (EQ-5D) and disease specific Aberdeen Varicose Vein Questionnaire (AVVQ).
The purpose of this study is to determine whether nivolumab is better than ipilimumab to prevent recurrence of melanoma.
Patients with a primary invasive melanoma are recommended to undergo excision of the primary lesion with a wide margin. There is evidence that less radical margins of excision may be just as safe. This is a randomised controlled trial of 1 cm versus 2 cm margin of excision of the primary lesion for adult patients with a primary invasive cutaneous melanomas >=1mm thick to determine differences in the rate of local recurrence and melanoma specific survival. A reduction in margins is expected to improve quality of life in patients
The aim of the study is to evaluate the effects of a the multimodal treatment with a web-based self-help program with cognitive behavioral therapy coaching and individual tailored physiotherapy on workability, health behavior and pain symptoms for persons with persistent pain.
Thyroid Associated Ophthalmopathy is condition affecting the eyes of about 10% of patients with Graves disease. Its combination of protrusion affecting the looks of the patient and pain is often severely affecting the quality of life among these patients. The standard treatment for this illness today is intravenous glucocorticoids together with methotrexate. The purpose of this study is to evaluate the effect of rituximab on patients that do not respond to or relapse after conventional therapy.
Severe childhood obesity is associated with both immediate and chronic health problems and a severe impact on psychosocial development. Medical and behavioural interventions rarely result in the significant, durable weight loss necessary to improve health outcomes. This is a randomised clinical trial where 50 adolescents, 13-16 years of age, will be randomised to either early bariatric surgery (Roux-en-Y gastric bypass) or intense conservative treatment and possibly surgery after two years of non-surgical treatment or as they have become 18 years.
This study is being performed as a post-approval safety study (PASS), per the Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicines Agency (EMA), to gather data on Translarna (ataluren) safety, effectiveness, and prescription patterns in routine clinical practice.
An open label randomised trial for adults with histologically confirmed measurable metastatic GIST who have received no other treatment for metastatic disease. The study aims to determine if an alternating regimen of imatinib and regorafenib has sufficient activity and safety in comparison to imatinib alone to warrant further evaluation as a first line treatment for metastatic GIST.
The aim of this study is to evaluate the external validity of a randomized controlled trial comparing choice of hip arthroplasty for elderly patients (>80 years) with a displaced femoral neck fracture. The hypotheses are that patient reported hip function, quality of life are better and healthier in those included in the randomized controlled trial than those excluded. The external validity of the randomized controlled trial is acceptable. A prospective randomized controlled trial is planned and patients with a displaced femoral neck fracture will be included and randomized between either a hemiarthroplasty or total hip arthroplasty. All patients screened will be included in a prospective cohort study for evaluation of the external validity of the randomized controlled trial. The prospective cohort study will consist of 3 different groups. Patients included in the randomized controlled trial will form group 1. Patients eligible for the randomized controlled trial but did not give their informed consent and therefore excluded, form group 2. Patients with a femoral neck fracture which by any reason were excluded form group 3. Primary endpoint is patient-reported hip function (Harris hip score) and pain on the operated extremity evaluated with VAS (Visual Analogue Scale) and patient reported quality of life evaluated with EuroQol (EQ-5D). Secondary outcome measurement are the frequency of the complications, periprosthetic fracture, dislocation, revision surgery due to wound infection (deep and superficial) and loosening of the components. Baseline data, age, sex, comorbidity, cognitive status, weight, height, motor function, complications and reoperations. Follow up is performed 1-2 years after surgery. Group 1 is followed up in the ongoing randomized controlled trial by visits to the orthopedic department at Danderyd Hospital. Group 2 and 3 are followed up by telephone interview 1-2 year after surgery.
Non-randomized study of 5 subjects that have been selected for prophylactic open surgery due to abdominal aortic aneurysm. During surgery the renal arteries are identified and subjected to about 60 seconds each of freezing by application of liquid nitrogen in dedicated catheters around the circumference of each artery. Another 5 patients that are not subjected to the freeze therapy serve as controls. Main outcome is change in ambulatory blood pressure levels.
