3 Clinical Trials for Various Conditions
The purpose of this placebo-controlled study is to evaluate the safety, tolerability and pharmacokinetics of a single dose regimen of human butyrylcholinesterase (HuBChE) in healthy adults at 3 ascending dosage levels administered IV. HuBChE, which occurs naturally in human plasma, is being evaluated for prophylaxis and treatment in the event of exposure to chemical nerve agents (as employed during chemical warfare or as an act of terrorism). Volunteers in each dosage cohort will be randomized to treatment with HuBChE active drug or normal saline placebo in a 3:1 ratio. The volunteers will remain in the study for 90 (+/- 7) days. For the first 3 days following dose administration, they will remain at the clinical trial site as inpatients and will be closely monitored for patient safety. Afterwards, they will return to the trial site (at pre-determined intervals) as outpatients for 8 further visits, where patient safety will be assessed.

The Vietnam Era Health Retrospective Observational Study (VE-HEROeS) is a national study on the health and well-being of Vietnam Veterans, including Blue Water Navy Veterans, as well as Veterans who served elsewhere during the Vietnam Era (1961-1975), and similarly aged U.S. residents who never served in the military. The investigators will invite approximately 43,000 Vietnam and Vietnam Era Veterans, and approximately 11,000 members of the general U.S. population to participate in VE-HEROeS. These individuals are scientifically selected to participate; the study is not able to accept volunteers. All participants in VE-HEROeS will be asked to fill out a questionnaire on their military service, general health, age-related conditions, health care use, and the health experiences of their children and grandchildren. A smaller group will be asked to provide the investigators with access to some of their medical records. Topics of special focus for the study include cognition, hepatitis C infection, and neurologic conditions.
