Subcutaneous Elafin in Healthy Subjects

Completed · Phase 1 · Has a placebo group

Conditions studied: Pulmonary Arterial Hypertension

In brief

A multiple-ascending-dose (MAD), randomized, placebo-controlled, blinded trial to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of Elafin in healthy adult subjects. The purpose of this study is to assess Elafin that is being developed for treatment of PAH. Elafin inhibits elastase, an enzyme that is increased in pulmonary hypertension and is a major factor in the development of PAH. Elafin will be administered subcutaneously daily for 7 days in normal healthy subjects followed over a 28 day time period.
