A Double-Blind, Multiple Ascending Dose Study to Assess Safety, Tolerability and Pharmacokinetics of DX-2930 in Hereditary Angioedema Participants

A Phase 1b, Double-Blind, Multiple Ascending Dose Study to Assess Safety, Tolerability and Pharmacokinetics of DX-2930 in Hereditary Angioedema Subjects

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics (PK) profile of multiple subcutaneous administrations of DX-2930 across a range of doses in HAE participants.

• History of exposure within the past 5 years to a monoclonal antibody or recombinant protein bearing an Fc domain
• Concomitant diagnosis of another form of chronic angioedema
• Use of long-term prophylaxis for HAE within 90 days prior to study
• Use of C1-INH that exceeds a total of 30 days within the past 90 days prior to study; any use of C1-INH within 7 days prior to study
• Exposure to angiotensin-converting enzyme (ACE) inhibitors or any estrogen-containing medications with systemic absorption within 90 days prior to study
• Exposure to androgens within 90 days prior to study
• Presence of an indwelling catheter
• Diagnosis of HIV
