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.
Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. QFR is estimated based on two angiographic projections. Studies have shown a good correlation with the present wire-based standard approach Fractional Flow Reserve (FFR) for assessment of intermediate coronary stenosis. The purpose of the FAVOR III Europe Japan study is to investigate if a QFR-based diagnostic strategy will results in non-inferior clinical outcome after 12 months compared to a standard pressure-wire guided strategy in evaluation of patients with chest pain (stable angina pectoris) and intermediate coronary stenosis.
Patients with a primary rectal cancer without detectable distant metastasis who after locoregional therapy only, meaning preoperative radio(chemo)therapy plus surgery have at least a 40% risk of not having a CRM negative resection or a recurrence, local or distant, within three years will be treated with the short course 5 x 5 Gy radiation scheme followed by four cycles of combination chemotherapy (capecitabine and oxaliplatin) and TME surgery
To demonstrate the added value of intraoperative pancreatoscopy in patients undergoing partial pancreatic resection for the treatment of Intraductal Papillary Mucinous Neoplasm (IPMN) as it pertains to detection of discontinuous (skip) lesions in the remnant pancreas; to generate a hypothesis for a subsequent randomized control trial.
This study consists of two periods. The objective of Period 1 is to evaluate the efficacy of upadacitinib in combination with a 26-week corticosteroid (CS) taper regimen compared to placebo in combination with a 52-week CS taper regimen, as measured by the proportion of participants in sustained remission at Week 52, and to assess the safety and tolerability of upadacitinib in participants with giant cell arteritis (GCA). The objective of period 2 is to evaluate the safety and efficacy of continuing versus withdrawing upadacitinib in maintaining remission in participants who achieved sustained remission in Period 1.
This is a study to evaluate pharmacokinetics, safety and tolerability of upadacitinib in pediatric participants with polyarticular course juvenile idiopathic arthritis. This study consists of three parts: Part 1 is multiple-cohort study that consists of two sequential multiple dose groups. Participants benefiting from the study drug with no ongoing adverse events of special interest or serious adverse events will have option to enroll in Part 2. Part 2 is open-label, long term extension study to evaluate safety and tolerability. Part 3 is an additional safety cohort to evaluate long-term safety and tolerability.
Atrial fibrillation is a heart rhythm disorder that often occurs after heart surgery. During atrial fibrillation blood cloths may form, predominantly in the left atrial appendage, a small sac in the wall of the left side of the heart. Some heart surgeons close this appendage to protect against stroke, particularly in patients with a history of atrial fibrillation, yet there is little evidence to support the efficacy and safety of this practice. We therefore conducted the Left Atrial Appendage Closure by Surgery (LAACS) study (2010-2016) were patients in whom the appendage was closed (by chance) suffered fewer brain damages that patients where it remained open. Although encouraging, these results were not only based on strokes, but also on scars without symptoms found in brain scans. The following LAACS-2 study will include a sufficient number of patients to determine whether future guidelines should advise to close systematically the left atrium appendage during a heart operation.
The purpose of the Trident® II project is to introduce a cup system that modernizes and streamlines Stryker's acetabular shell portfolio. The Trident® II Clusterhole HA Shell combines the history of Stryker's Trident® shells with plasma spray CpTi with HA coating. Plasma spray coating and HA is considered to be the gold standard in orthopaedics today. This coating will help the cup to achieve early stability and long term fixation. One of the causes for implant failure is loosening and osteolysis. Osteolysis can be triggered when metal or polyethylene wear particles from the implant or bearing surfaces migrate between implant and surrounding host bone tissue. With the development of sequential irradiated and annealed highly crosslinked polyethylene (X3) wear rates (mean proximal, 2-dimensional and 3-dimensional) have been substantially reduced to 0.001 mm/y, calculated between 1 year and 5 years. The Trident® II Clusterhole HA shells have a plasma sprayed CpTi coating compared to the arc-deposition CpTi coating on legacy Trident® shells, both designed to allow bone ongrowth. With this study the investigators want to prove equivalent implant fixation of both type of cups. The primary objective is the assessment of prosthetic fixation and migration results after two years of the Trident® II Clusterhole HA shell compared to the legacy Trident® Hemi HA shell by means of RSA. It is hypothesized that they will perform equally. The secondary outcome measure will be long-term (10-year) survival based on the two-year migration patterns combined with clinical factors and radiographic aspects. In order to identify other clinical parameters besides the fixation of the prosthesis components, clinical scores and radiographic aspects will be correlated with the RSA outcome. The 10-year results will be used to verify the predicted long-term survival results.
TDR implants for the lumbar spine are currently most 2- or 3-piece devices with a purely mechanical function that provide/restore mobility. Lately interest is growing on non-mechanical implants that could possibly provide/restore mobility, but also produce counterforces on mobility as in healthy discs. No previous comparison between these two concepts has been performed, neither on clinical outcome, neither on specific differences on facet-joint load and wear.
Extreme premature Children will at discharge from Karolinska Hospital and Södersjukhuset in Stockholm be asked to participate in a study, examining the effects of a home-visit based post-discharge program aiming at facilitating the interaction between infants and parents, improving the development of the children, and the parental mental health. The study is a randomized controlled Trial (RCT), hence 50% of the participants will be offered treatment as usual (TAU) with addition of an extended follow-up program. The interaction-based program consists of one initial visit at the hospital followed by nine home-visits and two telephone calls during the child's first year of life. The interventionists are skilled Healthcare professionals with several years of experience from caring for premature infants and their parents. All interventionists have successfully completed a one year further education program, delivered one day per week and containing theoretical lectures, practice with actual cases, supervision on the cases, visits to the different parts of the neonatal care chain and discussions with a representative from the premature family association Sweden.
This study follows up patients who receive standard treatment for prescription narcotic drug use disorder, including opioids, benzodiazepines, and benzodiazepine-like drugs (z-drugs), at a specialized addiction service. The overall goal is to evaluate the proportion of patients who reduce or cease using prescription narcotics and the factors associated with treatment outcomes. No new treatments will be tested. Instead, the results will be used as the basis for a future randomized controlled trial to optimize treatment for narcotic drug use disorder.
