    Why is this study being done?

    OBJECTIVES: I. To improve 4-year event-free survival (EFS) to 73% for young patients with bilateral Wilms tumor (BWT). II. To prevent complete removal of at least one kidney in 50% of patients with BWT by using prenephrectomy 3-drug chemotherapy induction with vincristine (vincristine sulfate), dactinomycin, and doxorubicin (doxorubicin hydrochloride). III. To evaluate the efficacy of chemotherapy in preserving renal units in children with diffuse hyperplastic perilobar nephroblastomatosis (DHPLN) and preventing Wilms tumor development. IV. To facilitate partial nephrectomy in lieu of nephrectomy in 25% of children with unilateral tumors and aniridia, Beckwith-Wiedemann syndrome (BWS), hemihypertrophy or other overgrowth syndromes, by using prenephrectomy 2-drug chemotherapy induction with vincristine and dactinomycin. V. To have 75% of patients with BWT undergo definitive surgical treatment by 12 weeks after initiation of chemotherapy.

  4. Nephrotic Syndrome Study Network Under the Rare Diseases Clinical Research Network

    Nephrotic Syndrome Study Network Under the Rare Diseases Clinical Research Network

    Location:

    Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    Idiopathic Nephrotic Syndrome (NS) is a rare disease syndrome responsible for approximately 12% of all causes of end-stage kidney disease (ESRD) and up to 20% of ESRD in children. Treatment strategies for Focal and Segmental Glomerulosclerosis (FSGS), Minimal Change Disease (MCD) and Membranous Nephropathy (MN), the major causes of NS, include high dose prolonged steroid therapy, cyclophosphamide, cyclosporine A, tacrolimus, mycophenolate mofetil and other immunosuppressive agents, which all carry significant side effects. Failure to obtain remission using the current treatment approaches frequently results in progression to ESRD with its associated costs, morbidities, and mortality. In the North American Pediatric Renal Trials and Collaborative Studies (NAPRTCS) registry, half of the pediatric patients with Steroid Resistant Nephrotic Syndrome required renal replacement therapy within two years of being enrolled in the disease registry. FSGS also has a high recurrence rate following kidney transplantation (30-40%) and is the most common recurrent disease leading to allograft loss. The prevailing classification of Nephrotic Syndrome categorizes patients into FSGS, MCD, and MN, if in the absence of other underlying causes, glomerular histology shows a specific histological pattern. This classification does not adequately predict the heterogeneous natural history of patients with FSGS, MCD, and MN. Major advances in understanding the pathogenesis of FSGS and MCD have come over the last ten years from the identification of several mutated genes responsible for causing Steroid Resistant Nephrotic Syndrome (SRNS) presenting with FSGS or MCD histopathology in humans and model organisms. These functionally distinct genetic disorders can present with indistinguishable FSGS lesions on histology confirming the presence of heterogeneous pathogenic mechanisms under the current histological diagnoses. The limited understanding of FSGS, MCD, and MN biology in humans has necessitated a descriptive classification system in which heterogeneous disorders are grouped together. This invariably consigns these heterogeneous patients to the same therapeutic approaches, which use blunt immunosuppressive drugs that lack a clear biological basis, are often not beneficial, and are complicated by significant toxicity. The foregoing shortcomings make a strong case that concerted and innovative investigational strategies combining basic science, translational, and clinical methods should be employed to study FSGS, MCD, and MN. It is for these reasons that the Nephrotic Syndrome Study Network is established to conduct clinical and translational research in patients with FSGS/MCD and MN.

    Use of Tolvaptan to Reduce Urinary Supersaturation: a Pilot Proof of Principle Study

    Location:

    Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    In this study the investigators propose to use a daily dose of 45 mg (30 mg at 8 AM and 15 mg at 4 PM). This relatively small well-tolerated dose is likely to persistently increase urine volume and reduce urine supersaturation and to be well tolerated by patients with kidney stone disease and normal renal function (see below). The twice-daily (8 AM and 4 PM) regimen is designed to produce a maximal AVP inhibition on waking with a gradual fall-off of effect during the night. To this end, a higher dose is used in the morning, with a lower dose in the afternoon.

    Why is this study being done?

    During this study visit, the investigator will draw one tube, about two teaspoonfuls (1 to 1 ½ teaspoons for children), of blood from your arm to obtain white blood cells. These white blood cells will be used as a source of DNA for genetic testing. We will use the isolated DNA to try to identify the gene that is defective in Dent Disease by comparing it with the structure of genes in normal individuals, patients with Dent Disease, and family members for Dent Disease.

    Multi-center Study of Metastatic Lung Tumors Targeted by Interventional Cryoablation Evaluation

    Location:

    Rochester, Minn.

    Trial status:

    Open for Enrollment

    Why is this study being done?

    Treatment for pulmonary metastatic disease may include surgery, chemotherapy, radiation therapy, or a combination of treatments. However, several variables may exclude patients from these treatments such as multiple tumors, multiple previous surgeries, pulmonary dysfunction, or co-morbid medical conditions. For these patients, percutaneous cryoablation may be a suitable option. Ablation of metastatic lung tumors is a rapidly expanding area within interventional oncology. Cryotherapy, radiofrequency, laser and microwave have all been shown to be effective. Cryotherapy offers a wide range of anatomic and tumor treatment options because of the ability to visualize the ice under imaging guidance and the preservation of collagenous tissue structure. Cryoablation has been extensively performed in the prostate and kidney with favorable outcomes reported in the literature. More recently, cryoablation has been shown to be safe in the treatment of lung tumors with CT guidance.
