Phase 1, Single Dose Study to Evaluate Safety, Pharmacokinetics, and Pharmacodynamics of MEDI5884

A Phase 1 Randomized, Blinded, Placebo-controlled Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of Single-Ascending Doses of MEDI5884 in Healthy Volunteers

A Phase 1, single dose study with 4 cohorts of ascending doses and an optional Japanese cohort designed to evaluate the safety, pharmacokinetics, and pharmacodynamics of MEDI5884 in healthy volunteers

This is a first time in human, phase 1, randomized, blinded, placebo-controlled study to evaluate the safety, pharmacokinetics and pharmacodynamics of single ascending subcutaneous doses of MEDI5884 in healthy volunteers (age 18-55). The study consists of 4 cohorts of increasing doses (8 subjects each) and an optional Japanese American cohort (24 subjects) for a total of 56 healthy subjects. The decision whether or not to dose escalate will be based upon data review by the Dose Escalation Committee. Subjects will be randomized 3:1 to MEDI5884 or placebo. Following screening, the study consists of a 3 day inpatient stay and follow up visits. The number of follow up visits depend on the cohort assigned.
