NCT00001803
The Von Hippel-Lindau (VHL) Disease Genetic Epidemiology Study is a family-based case-control study to be conducted by the National Cancer Institute. The study subjects are 603 individuals who were determined to belong to families with VHL disease confirmed through screening under NIH protocol #89-C-0086 between 1988 and 1998. There are 293 patient volunteers with VHL disease and 310 volunteer patients free of VHL disease, most of whom have already had genetic testing for mutations in the VHL gene. Adults as well as children aged 13 - 17 will be included. All subjects will give informed consent prior to participation; for minor subjects, assent will be obtained from the minor and consent from the parent/guardian. This protocol provides the potential to benefit people with VHL disease (although not necessarily the study subjects themselves) and possibly people with sporadic (non-hereditary) forms of the tumors which occur in VHL disease. The risks and discomfort associated with this study are minor. The present protocol is a new epidemiologic component to VHL research at NIH which will relate the expression of VHL tumors to lifestyle factors (tobacco and alcohol use; physical activity), occupational exposures, reproductive and hormonal factors, demographic factors, medication use, diet, and putative susceptibility genes. Information will be collected by telephone interview and a written, self-administered diet questionnaire. A cheek cell sample will be obtained for analyses of genetic polymorphisms. Medical records will be obtained to document events reported by the subject at interview. Primary comparisons will be between VHL patients with a particular manifestation and VHL patients who are free of that condition. Additional comparisons may be made with unaffected family members who lack a mutation in the VHL gene, as appropriate.

NCT04136808
The primary purpose of this expanded access program is to evaluate safety and tolerability of enfortumab vedotin (EV) in participants in the United States with locally advanced or metastatic urothelial carcinoma (UC) who have exhausted standard of care therapies and are not eligible to participate in an ongoing EV clinical study. This program will also evaluate the efficacy of EV.
NCT02574390
Creation of a large repository of induced pluripotent stem cells (iPSC), bio-fluid samples (blood and spinal fluid (optional)), and cell lines for ALS gene identification. This will be combined carefully with collected measures of the pattern of the symptoms people with ALS have and how these change over time. People with other motor neuron diseases and healthy controls will be included as comparisons
NCT00340548
Background: Over 80% of the hemophiliac population who became infected with HIV prior to 1985 are also co-infected with HCV. Thus, hemophiliacs represent an important population for studies of the natural history of these chronic viral infections. Moreover, the high rate of co-infection makes it an ideal group for assessing the interaction between the viruses and the relationship between viral specific immune responses and clinical progression. Although the hemophiliac poulation is unique, co-infection by these chronic viral pathogens is becoming increasingly common, particularly amongst intravenous drug users, who account for approximately 25% of the HIV-1 epidemic in the United States. Objectives: The aim of this study is to determine if polymorphism in the promoter region of TH1 and Th2 cytokines are associated with (1) intracellular cytokines levels in CD4 + Tcells, (2) Human Immunodeficiency Virus (HIV) and Hepatitis C virus (HCV) viral loads, and (3) clinical progression of HIV1 to AIDS in hemophiliacs. Eligibility: The current proposal will investigate host genetic factors related to HIV-1 and HCV immunopathogenesis by studying children and adolescents enrolled in the Hemophilia Growth and Development Study (HGDS). Design: This study is in collaboration with the principle investigators of the Hemophilia Growth and Development Study (HGDS) as part of a grant "Pathogenesis of HIV and HCV in Hemophilia: HGDS-3" with funding support by NIH/NICHD for the period 9/25/01 through 8/31/2005. This multicenter, United States study represents a well-characterized, prospectively followed cohort of HCV-infected hemophiliacs, of whom 207 are HIV-1 co-infected. Enrollment of the hemophiliac cohort was completed between 3/89 and 6/90. The final observation of the cohort (follow-up 16) was concluded during 7/98. No new samples or clinical data will be collected on this population. The LGD plays two roles in this project: (1) an administrative role overseeing the withdrawal, handling, and transport of samples from the HGDS/LGD and central repositories at the NCI-Frederick, and (2) a scientific role continuing investigations to determine the role of host genetic factors in Th1 and Th2 immune response and regulation of HCV and HIV viral replication..
NCT03620110
The purpose of this study is to collect whole blood samples from women with viable pregnancies of at least 10 weeks gestation (at any risk for fetal chromosomal anomaly) for future testing with an investigational noninvasive prenatal test(s) (NIPTs), and to establish clinical truth compared to a clinical reference standard.
NCT03710707
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of multiple oral doses of DNL201 in subjects with Parkinson's disease.
NCT03165227
The main objective of this trial is the safety and tolerability of 3 multiple rising oral doses of BI 685509 over 28 days in male and female patients with Diabetic Nephropathy (DN) as adjunctive to Angiotensin Converting Enzyme inhibitor (ACEi) or Angiotensin Receptor Blocker (ARB). Another objective is the change in Urine Albumin Creatinine Ratio (UACR), an important diagnostic marker of nephropathy.

NCT01183689
The Study of Novel Approaches for Prevention (SNAP) is randomized trial designed to test whether behavioral interventions based on self-regulation can prevent weight gain in young adults (18-35 years; body mass index (BMI) 21-30 kg/m2). Two different self-regulation interventions for weight gain prevention will be compared in this trial; one intervention will focus on making small, consistent, changes in eating and exercise behavior to prevent weight gain or reverse weight gain if it occurs, whereas the other will emphasize larger changes in eating and exercise that occur periodically, with a goal of producing weight loss and thereby providing a buffer against anticipated weight gains. The primary aim of the trial is to test whether the magnitude of weight gain from baseline across an average three-year follow-up differs across the three groups, with the hypotheses that weight gain will be greater in the Control group than in either intervention and greater in the Small Changes than Large Changes group. SNAP-E (Extension) will determine whether the effects of the intervention can be maintained over an additional 3 years (i.e. through a total of 6 years).
NCT03200912
The objective of this study was to evaluate the safety and therapeutic equivalence of generic ingenol mebutate gel, 0.015% to Picato gel, 0.015% by establishing the therapeutic comparability of the two active products and the superiority of the two active products over the vehicle gel in the treatment of AK on the face and scalp.
NCT02844985
The study is intended to identify gene polymorphisms significantly associated with specific behavioral- and preoccupation-typologies of sexual addiction, and to identify additional potential genetic markers of sexual addiction. Research subjects with sexual addiction will be identified from the out-patient and in-patient populations of the investigative sites. Research subjects in the Control Group will be identified from the general population and from the student body of selected colleges. Approximately 1100 subjects will be enrolled in the study. Anticipating 10% drop-out, this is intended to generate a population of approximately 500 men and women clinically diagnosed with sexual addiction, and approximately 500 healthy men and women who do not meet diagnostic criteria for sexual addiction nor have psychopathology who will serve as the control population.
