IC14 in Adult Patients With Dengue Fever

The study will be conducted in two parts and will include an open label phase of a single dose of IC14 (Part A) and a randomized phase of multiple doses of IC14 and placebo (Part B). Up to 52 patients will be enrolled in both parts of the study.

Part A will consist of 12 patients given one of three doses of IC14 as a single dose open-label . Each patient must complete 14 days before the enrollment of subsequent patients. Part A subjects will be hospitalized for 4 days. During and at the end of 4-day admission to the clinical research unit, and on Study Days 5, 6, 7, 14, 21 and 32, Part A patients will have their health status assessed. The last subject in Part A must complete 32 days of participation before Part B of the trial is opened.

Part B consists of 40 patients randomized equally to one of 4 dosing regimens which will include a single dose or multiple doses of IC14 or placebo given at different dosing frequencies. In Part B, Cohort 1 and 2 subjects (single dose) will be inpatient for 4 days and Cohort 3 and 4 subjects (four daily doses) will be inpatient for 5 days. During and at the end of the admission to the clinical research unit, and on Study Days 5, 6, 7, 14, 21 and 32, Part B patients will have their health status assessed.
