A five-year prospective cohort study following 240 patients who have autosomal-dominant polycystic kidney disease (PKD) to determine whether changes in anatomic characteristics of their kidneys as measured by magnetic resonance imaging will be useful in providing surrogate measures for disease progression. CRISP's overall goal is to develop methods that would facilitate shortening the observation period necessary to determine efficacy of treatment interventions in PKD patients. Specific goals of this study are to: * Quantify cyst growth and ascertain severity of renal parenchymal involvement by sequential measurement of total kidney volume and the ratio of intact parenchyma to renal parenchyma occupied by cysts over time * Establish useful clinical correlations of imaging data with other markers of disease progression * Identify and test other potential markers or indices of disease progression, for example, assessment of loss of heterozygosity of renal cells shed in the urine, or other markers, in cohorts of patients with PKD * Gain information about the cost-effectiveness, patient acceptability, and advantages and disadvantages of different imaging techniques used serially in patients with PKD. Some experience has been gained in establishing that repeat imaging of the same PKD patient, using these techniques, yields reproducible estimates of kidney size and the proportion of renal parenchyma occupied by cysts. MRI may also have the advantage of permitting simultaneous estimation of GFR. Ultrasound has the advantage of being more cost-effective and perhaps more acceptable to patients for repetitive studies, but the measurements may be less accurate and reproducible. Nonetheless, there is very limited experience in applying these techniques to follow progression of the renal disease. Development of improved, reproducible imaging methods that assess cyst growth and provide markers of disease progression could markedly improve the feasibility of clinical trials. Participating clinical centers are Emory University, the Mayo Clinic, University of Kansas, and the University of Alabama at Birmingham. The data coordinating and imaging analysis center is at Washington University. (PI has since moved to University of Pittsburgh) The study found that kidney enlargement resulting from the expansion of cysts is continuous, quantifiable, and associated with the decline of renal function. Cystic expansion occurs at a consistent rate per individual, although it is heterogeneous in the population, and that larger kidneys are associated with more rapid decrease in renal function. These anatomic characteristics of patient kidneys may provide useful surrogate measures for disease progression, and hence enhance the development of targeted therapies for autosomal dominant PKD. CRISP III is a five-year prospective cohort study to follow ~170 remaining autosomal dominant polycystic kidney disease (ADPKD) patients who were part of the original CRISP cohort study. CRISP III will verify and extend the preliminary observations of CRISP to determine the extent to which quantitative (kidney volume and blood flow, and hepatic and kidney cyst volume) or qualitative (cyst distribution and character) structural parameters predict renal insufficiency and develop and test new metrics to quantify and monitor disease progression. Urine metabolites and the genome will be correlated with the progression of disease to look for new, predictive disease biomarkers. This information from CRISP III will help determine if the kidney enlargement, blood flow, cyst distribution, or urine metabolites can function as an informative surrogate measure for disease progression.

Multi-center double-masked, placebo-controlled randomized clinical trial designed to evaluate the long-term efficacy of finasteride, or doxazosin, or the combination of both, in delaying or preventing the clinical progression of symptomatic benign prostatic hyperplasia (BPH). MTOPS was the largest and longest study to test whether drug therapy can prevent or delay the noncancerous growth of the prostate. A unique feature of MTOPS that has not been done in prior studies of pharmacotherapy of BPH is the biopsy substudy. A total of 1,082 volunteers from the 2,931 participants randomized during the full-scale phase are currently participating in this substudy. Biopsies of the prostate will be obtained on these volunteers at predetermined times during the course of the trial to evaluate the status of the prostate at key event times. The purpose of the substudy was to provide additional information regarding the histopathobiology of BPH and to test existing biomarkers for their prognostic ability regarding response to drug therapy.

16-center, randomized clinical trial investigating the long-term health consequences of an intensive lifestyle intervention program designed to achieve and maintain weight loss by decreased caloric intake and increased physical activity in overweight volunteers with type 2 diabetes. The Look AHEAD cohort comprises approximately 5,000 overweight or obese participants with type 2 diabetes, aged 45-76. Participants were randomized to one of two interventions: an intensive lifestyle intervention designed to produce and sustain weight loss over the long term or a diabetes support and education arm. Participants will be followed for a total of 11 to 13.5 years from randomization. The primary hypothesis is that the incidence rate of the first post-randomization occurrence of a composite outcome, which includes * cardiovascular death (including fatal myocardial infarction and stroke), * non-fatal myocardial infarction, * hospitalized angina, and * non-fatal stroke, over a planned follow-up period of up to 13.5 years will be reduced among participants assigned to the Lifestyle Intervention compared to those assigned to the control condition, Diabetes Support and Education. Look AHEAD will also test for reductions in the incidence of three secondary composite outcomes and examine the effect of the intervention on cardiovascular disease risk factors, diabetes control and complications, general health, and quality of life, and psychological outcomes. The cost and cost-effectiveness of the Lifestyle Intervention relative to Diabetes Support and Education will be assessed. The Look AHEAD intensive lifestyle intervention ended September, 2012. Participants continue to be followed to determine the long-term effects of the intervention on health outcomes.

Randomized controlled clinical trial to understand how increasing hemodialysis to six times a week from the standard of three times a week may result in improved heart health. Subjects were recruited from dialysis units associated with designated Clinical Centers in the U.S. and Canada and followed for 1 year. Subjects will be randomized to either conventional hemodialyis Daily HD delivered for at least 2.5 hours (typically 3 to 4 hours), 3 days per week, or to more frequent hemodialysis delivered for 1.5 - 2.75 hours, 6 days per week. The study has two co-primary outcomes: 1) a composite of mortality with the change over 12 months in left ventricular mass by magnetic resonance imaging, and 2) a composite of mortality with the change over 12 months in the SF-36 RAND physical health composite (PHC) quality of life scale. In addition, main secondary outcomes have been designated for each of seven outcome domains: 1) cardiovascular structure and function (change in LV mass), 2) health-related quality of life/physical function (change in the PHC), 3) depression/burden of illness (change in Beck Depression Inventory), 4) nutrition (change in serum albumin), 5) cognitive function (change in the Trail Making Test B), 6) mineral metabolism (change in average predialysis serum phosphorus), and 7) clinical events (rate of non-access hospitalization or death). Hypertension and anemia are also main outcome domains, but without designation of single first priority outcomes.

Study designed to test the hypothesis that African-Americans respond less well to combination pegylated interferon and ribavirin therapy than Caucasian-Americans who have chronic hepatitis C genotype 1 and who were not previously treated with either interferon or ribavirin. Reasons for differences in response, regardless of race, will be studied. All patients were treated with combination therapy of pegylated interferon and ribavirin for 48 weeks, and were followed for an additional 48 week safter cessation of therapy. 400 patients, half African-American and half Caucasian American, from 8 clinical centers with the goals of establishing rates of response to optimal current therapy in the two ethnic groups, identify factors predictive of response, establish patterns of viral kinetics in response to antiviral therapy, and test hypotheses concerning viral and host factors determining response to therapy. Four ancillary studies designed to elucidate biological and virological basis for non-response are also included in Virahep-C. Additionally, the study has central facilitates for pathology, the virological testing laboratory and a serum/tissue repository.

Randomized, multicenter, double blind, placebo controlled clinical trial of phytotherapy for benign prostate symptoms among men. The CAMUS trial will test Saw palmetto in about 369 men. Men who decide to be part of the CAMUS trial will be given one out of two possible treatments at random. One out of every two men would get an inactive placebo treatment. One out of every two men would get Saw palmetto pills. This kind of scientific study is the best way to find out if the plant extracts really work to prevent men with benign prostatic hyperplasia (BPH) from getting worse. During the study, men will not know which of the two treatments they are assigned to. They will be followed very closely by a study team every 12 weeks to see how they are doing. Men in the CAMUS trial will be studied over 72 weeks. Ten clinical centers will participate in the trial. They are located at: Columbia University, NY, NY; New York University, NY, NY; University of Texas Southwestern Medical Center, Dallas, Texas; University of Colorado, Denver, CO; Washington University, St. Louis, MO; Yale University, New Haven, CT; Queens University, Hamilton, Ontario, Canada; Northwestern University, Chicago, IL; University of Maryland, Baltimore, MD; University of California at San Francisco, San Francisco, CA.

Randomized, multicenter, double-blind study to determine if renin angiotensin medications, either losartan (angiotensin II blocker) or enalapril (converting enzyme inhibitor), can prevent or delay the onset of diabetic kidney disease in patients with type 1 diabetic patients who do not have hypertension, diabetic nephropathy, or predictive levels of microalbuminuria. Two hundred eight five patients ages 16-61 with 2-20 yrs of Type 1 Diabetes Mellitus and no renal functional abnormalities were randomized into a parallel, double-blind, placebo-controlled study involving 3 groups (95 patients/group). Each group received an angiotensin-converting enzyme inhibitor (ACEI) (enalapril), or an angiotensin II receptor blocker (Losartan), or placebo. All patients had their usual Diabetes Mellitus (DM) management. Baseline studies included measures of glomerular filtration rate (GFR), urinary albumin excretion rate (UAE), blood pressure (BP), and a percutaneous renal biopsy. Patients were followed by quarterly measures of BP, HbA1C, UAE, and drug compliance. There were annual measures of GFR and a repeat renal biopsy after 5 yrs in the study. The main endpoint is kidney structural changes over time, especially mesangial fractional volume (v(Mes/glom)). Secondary endpoints will be other DN structural measures and measures of kidney function (UAE, GFR). These studies will determine whether rennin angiotensin system blockage in the early stages of DN can prevent the early kidney structural changes in this important disorder. Ancillary studies will evaluate the effects of treatment group on the development and progression of diabetic retinopathy and will develop predictors of study participants'''' compliance. Baseline, 2.5 and 5 year retinal fundus photographs in the RASS patients were obtained.

NOTE: The T1D-RAID program is not currently accepting applications. Cooperative program that makes available, on a competitive basis, NCI resources for the pre-clinical development of drugs, natural products, and biologics to facilitate translation to the clinic of novel, scientifically meritorious therapeutic interventions for type 1 diabetes and its complications. A partial listing of those services includes: high-throughput screening, studies in animal models, formulation, pharmacology and toxicology studies, and bulk substances acquisition. Requests to T1D-RAID are brief (20 pages or less), and should clearly outline the resources required to ready the proposed therapeutic agent for clinical trials. T1D-RAID should enable entry into the clinic of promising molecules that are not otherwise likely to receive an adequate and timely clinical test. T1D-RAID is designed to accomplish the tasks that are rate-limiting in bringing discoveries from the laboratory to the clinic. Once a project has been approved, NIDDKstaff interact directly with the Principal Investigator (PI). NCI contractors perform the T1D-RAID-approved tasks under the direction of NIDDKand NCI staff. The required tasks will vary from project to project. In some cases T1D-RAID will support only one or two key missing steps necessary to bring a compound to the clinic; in other cases it may be necessary to supply the entire portfolio of development requirements needed to file an IND. Examples of tasks that can be supported by T1D-RAID include, but are not limited to: * Definition or optimization of dose and schedule for in vivo activity * Development of pharmacology assays * Conduct of pharmacology studies with a pre-determined assay * Acquisition of bulk substance (GMP and non-GMP) * Scale-up production from lab-scale to clinical-trials lot scale * Development of suitable formulations * Development of analytical methods for bulk substances * Production of dosage forms * Stability assurance of dosage forms * Range-finding initial toxicology * IND-directed toxicology, with correlative pharmacology and histopathology * Planning of clinical trials * Regulatory affairs, so that FDA requirements are likely to be satisfied by participating investigators seeking to test new molecular entities in the clinic * IND filing advice The output of T1D-RAID activities will be both products and information that will be made fully available to the originating investigator for support of an IND application and clinical trials. T1D-RAID does not sponsor clinical trials.
