This study will assess the safety, tolerability and pharmacokinetics of sitagliptin in 10 to 17 year old diabetic patients.

This study will use imaging to look at tumor response to erlotinib (Part I) and the combination of erlotinib and MK0646 (Part II).

To demonstrate the efficacy/safety of FOSAMAX PLUS D.

The study will estimate the effects of rolofylline, alone and in addition to loop diuretic therapy on pulmonary capillary wedge pressure and other hemodynamic parameters, in patients with heart failure and renal impairment.

This study will evaluate the safety and treatment effect of 50 mg MK0822 with Vitamin D vs placebo with Vitamin D in postmenopausal women with low bone density.

Many IBD patients take immunosuppressive agents and we are uncertain as to their capacity to mount a truly protective response after vaccination. If IBD patients do not have an adequate immunological response, they may need to increase the dosage or get booster shots. Many clinicians who treat patients with autoimmune diseases are asking if the vaccine is safe and effective. Thus, this study has important clinical and public health significance because more than one million people in the United States who have been diagnosed with IBD. There is not much studied about HPV and immunocompromised patients. Research on healthy women who were immunized with a set of three HPV vaccines demonstrated significantly increased antibody titers. In addition, they had significantly reduced HPV incident and persistent infection and HPV-related disease (cervical, vulvar, and vaginal cancers, cervical intraepithelial neoplasia, genital warts) through five years of follow-up compared to controls who received a placebo. The HPV vaccine was well tolerated without significant side effects. The aims of this research are to measure the immune response in 9-26 year old IBD patients who are on immunosuppressive agents after receiving the HPV vaccine compared with controls. We will also evaluate the number and type of vaccine-associated adverse events as well as the disease activity and flare-ups that occur after each dose of vaccine. We hypothesize that IBD patients on immunosuppressive therapy will have an equivalent immune response to HPV types 6, 11, 16 and 18 at one month postdose 3 compared to healthy age-matched historical controls. The patient population includes IBD patients who are on immunosuppressive medications. Recruiting approximately 100 patients will provide adequate power for the study. A blood sample will be taken from all IBD patients to evaluate baseline antibody levels and markers (e.g., ESR, CBC, albumin) before or immediately after immunization with the HPV vaccine. Lab tests will be redrawn at 7 months to evaluate the level of antibody titers and follow the markers. During the study, we will track basic laboratory measures, disease status by using the Pediatric Crohn's Disease Active Index or Harvey-Bradshaw Index for UC, side effects from the vaccinations, and other adverse events.

A study to evaluate the efficacy and safety of sitagliptin and pioglitazone co-administration in comparison with sitagliptin and pioglitazone monotherapy in patients with type 2 diabetes

A study to evaluate the tolerability of electrostimulation applications with an investigational device known as the MedPulser DDS.

The main aim of the study is to develop a method that allows responders to be distinguished from non-responders before long-term treatment is initiated. Subsidiary aims are to record changes in pulmonary functional parameters, NO concentrations and peak flow variability, the use of beta2 sympathomimetics and the asthma symptom score.

Part A. The purpose of this study is to assess the effects of 6 weeks of treatment with, simvastatin, losartan or pioglitazone compared to placebo on the RNA expression profile of lower extremity peripheral arterial atherosclerotic plaque. Part B. The effect of simvastatin, losartan or pioglitazone compared to placebo on protein and lipid biomarkers in lower extremity peripheral arterial atherosclerotic plaque.
