There are about 9403 clinical studies being (or have been) conducted in Switzerland. 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 investigators plan to conduct a two arm study, to compare failure rates in the central nervous system (CNS) and genital compartment in virologically fully suppressed patients continuing a highly active antiretroviral therapy (HAART) versus patients switching to ritonavir boosted lopinavir (Kaletra®) HIV-monotherapy. The study is composed of two phases of 48 weeks duration. In addition, neuropsychological tests (Color trial test A 1 and 2; Grooved pegboard; EWIA Digit Symbol form) and evaluation of side effects will be performed.
This study compares the effectiveness and safety of the combination of anidulafungin and voriconazole compared to that of voriconazole alone (which is generally considered the standard of care) for the treatment of Invasive Aspergillosis.
This extension study is designed to provide long-term safety and efficacy data beyond 12 months up to Month 36.
Any efforts to spare patients with T1 carcinomas of the rectum from low anterior resection or even abdominoperineal resection are linked to the risk of locoregional recurrence of about 10% (range, 0-24). This is tolerated in the view of the morbidity and mortality risk related to transabdominal resection, which is as high as 7-68% and 0-6.5%, respectively. Accordingly, in addition to transanal local excision various adjuvant therapy schemes with chemo- and/or radiotherapy were developed, given the uncertainty about the lymph node stage. Another approach was to identify histological risk criteria in the primary tumor in terms of defining the limits of rectum-sparing therapy. In earlier experimental and clinical studies the investigators researched and applied dorsoposterior extraperitoneal pelviscopy, i.e. perineal access to the soft-tissue areas of the minor pelvis using minimally invasive surgery. in T1 carcinoma of the rectum this technique becomes all the more significant, as the perineal approach makes it possible to perform an endoscopic posterior mesorectal resection (EPMR) in combination with rectum-sparing surgery Thereby the relevant lymphatic field of the lower rectum can be removed and histologically examined. As a consequence EPMR should lower the loco-regional recurrence rate, since the most common causes of such are pre-existent but so far not detectable lymph node metastases besides the incomplete resection of the primary tumor.
This extension study is designed to provide long-term safety and efficacy data beyond 12 months up to Month 36.
The purpose of the study is to determine whether a single, pre-operative dose of cefuroxime is effective in preventing surgical site infection in patients undergoing surgery for herniated disk
Neurally adjusted ventilatory assist (NAVA) is a new concept of mechanical ventilation. NAVA delivers assist to spontaneous breathing based on the detection of the electrical activity of the diaphragm. We study the effect of changing ventilatory parameters on the patient's breathing pattern during NAVA.
The main objective of the trial is to compare Invasive Disease-Free Survival (IDFS) of patients randomised to treatment with adjuvant chemotherapy alone or to adjuvant chemotherapy with 1 year of bevacizumab. The secondary objectives of this trial are to: - compare Overall Survival (OS), Breast Cancer-Free Interval (BCFI), Disease- Free Survival (DFS) and Distant Disease-Free Survival (DDFS) of patients randomised to treatment with adjuvant chemotherapy alone or to adjuvant chemotherapy in combination with 1 year of bevacizumab - evaluate the safety and tolerability of bevacizumab An exploratory sub-study (not reported here) was to identify biomarkers (from tumour or serum) predictive of toxicity and for the level of benefit from the addition of bevacizumab to standard adjuvant systemic treatment.
Sevoflurane preconditioning and cardiovascular protection against ischemia/reperfusion injury. Study hypothesis: The volatile anesthetic sevoflurane at subanesthetic concentrations achieves endothelial protection against ischemia/reperfusion injury and reduces inflammatory markers in the circulation
RATIONALE: Giving chemotherapy before an autologous stem cell transplant stops the growth of tumor cells by stopping them from dividing or by killing them. It also prepares the patient's bone marrow for the stem cell transplant. The stem cells are given to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. Giving isotretinoin after transplant may kill any remaining tumor cells. It is not yet known which combination chemotherapy regimen is more effective when given before a stem cell transplant and isotretinoin in treating neuroblastoma. PURPOSE: This randomized clinical trial is studying two different combination chemotherapy regimens to compare how well they work when given before a stem cell transplant and isotretinoin in treating young patients with high-risk neuroblastoma.
