    A Phase III Surgical Trial to Evaluate the Benefit of a Standard Versus an Extended Pelvic Lymphadenectomy Performed at Time of Radical Cystectomy for Muscle Invasive Urothelial Cancer

    Location:

    Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    OBJECTIVES: Primary - To compare disease-free survival (DFS) of patients with muscle-invasive urothelial carcinoma of the bladder undergoing radical cystectomy with extended pelvic lymph node dissection (PLND) or standard pelvic lymphadenectomy. Secondary - To compare overall survival (OS) of patients randomized to extended PLND versus those randomized to standard pelvic lymphadenectomy. - To evaluate operative time; whether or not nerve sparing was performed, intraoperative, peri-operative and 90-day morbidity and mortality; length of hospital stay; histology (pure urothelial versus mixed); lymph node counts and lymph node density; adjuvant chemotherapy received; and local and retroperitoneal soft tissue recurrence in patients randomized to extended PLND versus those randomized to standard pelvic lymphadenectomy. - To collect peripheral blood and two paraffin-embedded blocks of the primary tumor for translational medicine studies, including circulating tumor cells (CTCs) and markers of epithelial and mesenchymal transition, and correlate these findings with pathologic T stage and node metastasis as well as DFS and OS. OUTLINE: This is a multicenter study. Patients are stratified according to prior neoadjuvant therapy (yes vs no), clinical stage (T2 vs T3 vs T4a), and Zubrod performance status (0-1 vs 2). Patients are randomized to 1 of 2 treatment arms. - Arm I: Patients undergo radical cystectomy and standard pelvic lymphadenectomy. - Arm II: Patients undergo radical cystectomy and extended pelvic lymphadenectomy. Blood and tumor specimens may be collected periodically for translational studies. After completion of study therapy, patients are followed up periodically for 6 years.

    EARLY DETECTION OF BROKEN HEARTS IN CANCER PATIENTS: BEVACIZUMAB, SUNITINIB AND HEART FAILURE

    Location:

    Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    A total of 100 individuals (50 receiving BVZ and 50 receiving Sunitinib) will be prospectively enrolled . (80 at Mayo Clinic [40 receiving BVZ and 40 receiving Sunitinib] and 20 at St. Boniface General Hospital (SBGH)). Patients receiving either BVZ 5mg/kg iv every 2-3 weeks for colorectal cancer or Sunitinib 50 mg po daily for advanced Metastatic renal cell carcinoma will be screened for potential eligibility in the study. For metastatic renal cancer treatments, Sunitinib doses are (oral) 50 mg once a day for 4 weeks followed by a two week off period. The six week cycle is then repeated. In case of toxicities observed with the dose, a 25% reduction in the daily dose during the "on" period is performed (37.5 mg). Patients will be studied at 7 time points: i) Baseline; ii) Day 1; iii) Day 5; iv) 4-6 weeks ; v) 3 months; vi) 6 months after the initiation of both drugs (BVZ and Sunitinib) ; and vii) 12 months after the initiation of BVZ drug only (Figure 1). Three visits (baseline, 4-6 weeks , and 3 months) are considered part of standard clinical care, and four visits are for research. At each visit, in addition to standard of care provided by the Oncologist, blood will be drawn to measure high sensitivity troponin-T (hsTnT) and Natriuretic-proBNP. The patients will also undergo a TTE with tissue velocity imaging (TVI), strain and left ventricular opacification (LVO) and myocardial perfusion at each time point. EndoPAT test will also be performed at baseline, and 3 months. The baseline, 4-6 weeks, and 3 month visits will be part of your standard clinical care and followup.

    Rochester, Minn. View Summary

    Renal Tumors Classification, Biology, and Banking Study

    Location:

    Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    PRIMARY OBJECTIVES: I. Classify patients with renal tumors by histological categorization, surgico-pathological stage, presence of metastases, age at diagnosis, tumor weight, and loss of heterozygosity for chromosomes 1p and 16q, to define eligibility for a series of therapeutic studies. II. Maintain a biological samples bank to make specimens available to scientists to evaluate additional potential biological prognostic variables and for the conduct of other research by scientists. SECONDARY OBJECTIVES: I. Monitor outcome for those patients who are not eligible for a subsequent therapeutic study. II. Describe whether the pulmonary tumor burden correlates with outcome in patients with stage IV disease. III. Describe the sensitivity and specificity of abdominal computed tomography (CT) scan by comparing it with surgical and pathologic findings for identification of local tumor spread beyond the renal capsule to adjacent muscle and organs, lymph node involvement at the renal hilum and in the retroperitoneum, preoperative tumor rupture, and metastases to the liver. IV. Compare the sensitivity and specificity of pre-operative abdominal CT scan and MRI for the identification and differentiation of nephrogenic rests and Wilms' tumor in children with multiple renal lesions. V. Correlate the method of conception (natural vs assisted reproductive technology) with the development of Wilms' tumor. OUTLINE: This is a multicenter study. Tumor tissue, blood, and urine samples are collected for research studies, including immunohistochemistry. CT scans and magnetic resonance imaging (MRIs) are also performed. Loss of heterozygosity analyses (chromosome 1p and 16q) are performed by extraction of DNA. DNA polymorphisms are assayed by polymerase chain reaction using standard methodology. Leftover specimens are archived for future studies. Patients are followed periodically for 5 years.

  9. A Randomized, Placebo Controlled Clinical Trial of SOM230 (Pasireotide LAR) In Severe Polycystic Liver Disease

    Rochester, Minn. View Summary

    A Randomized, Placebo Controlled Clinical Trial of SOM230 (Pasireotide LAR) In Severe Polycystic Liver Disease

    Location:

    Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    Pasireotide (SOM230) is a novel multi-receptor-targeted analog that has high affinity for four of the five SST receptor subtypes (SSTr1, SSTr2, SSTr3 and SSTr5); it has a 40-fold higher affinity and 158-fold higher functional activity for the SST5 receptor than octreotide. Because of its broad receptor binding profile, pasireotide may be more potent in Polycystic Liver Disease (PLD) than octreotide. In this randomized double blind placebo controlled trial the investigators will compare SOM230 treatment to placebo for 12 months in patients with PLD. The primary endpoints will be assessed at 12 months and patients receiving placebo then crossed over to SOM230, permitting all participants to receive SOM230 for the subsequent two years. Magnetic resonance imaging (MRI) will be used to assess liver volume - the primary endpoint, which will be assessed at baseline, end of years 1 and 3. This study will assess the efficacy and safety of SOM230 in reducing total liver volume and improving quality of life over 12 months. (The investigators will not be assessing efficacy at 24 months.) The therapy way be effective in PLD but also may prove to be effective for many more patients with Polycystic Kidney Disease (PKD) which will be evaluated using eGFR and kidney volume using MRI. The investigators plan to add other sub-sites in other locations.
