Study to Assess the Tolerability and Safety of Ecallantide in Children and Adolescents With Hereditary Angioedema

Hereditary Angioedema Types I and II Clinical Trial

Official title: A Multicenter, Open-Label Study to Assess the Tolerability and Safety of a Single, Subcutaneous Administration of Ecallantide in Children and Adolescents With Hereditary Angioedema

Status Withdrawn

Clinical Trial Summary

The objective of this study is to evaluate the safety and tolerability of a single Subcutaneous (SC) dose of Ecallantide in children and adolescents with Hereditary Angioedema (HAE).

Clinical Trial Description

This pilot study is an open-label, non-randomized, single-arm study to evaluate the tolerability and safety of a single SC administration of ecallantide in up to approximately 10 pediatric subjects with HAE during an initial acute attack. The study is planned to enroll subjects 2 through 15 years of age who present with an acute cutaneous, abdominal, or laryngeal HAE attack. No more than 3 study sites will be included until a goal of 10 patients is achieved. After treatment for an initial attack, one additional open label treatment with ecallantide will be offered to subjects contingent upon having been treated previously and presenting with a subsequent acute cutaneous, abdominal, or laryngeal attack of HAE at least 7 days after initial treatment. Open-label treatment for a second HAE attack will continue until 10 patients have been treated for an initial attack. Safety evaluations will be performed at each subsequent ecallantide-treated attack as for the initial treated attack ;
