ACZ885 for the Treatment of Abdominal Aortic Aneurysm (AAA)

This study has been terminated.
(The results of a third interim analysis (ad hoc) indicated a lack of efficacy and futility in continuing the trial.)

This study was designed to assess the safety, tolerability and efficacy of ACZ885 on aneurysmal growth rate in subjects with abdominal aortic aneurysms (AAA). The purpose of the study was to provide data to enable decisions regarding the further development of ACZ885 for subjects with abdominal aortic aneurysms. The design of this study addressed the primary objective of evaluating the change in aneurysmal size in subjects with AAA as a result of treatment with ACZ885.

Condition Intervention Phase
Abdominal Aortic Aneurysm (AAA) Drug: ACZ885 Drug: Placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Official Title: A Randomized, Double-blind, Placebo-controlled, Multiple Dose Study of Subcutaneous ACZ885 for the Treatment of Abdominal Aortic Aneurysm

Primary Outcome Measures:
  • Change From Baseline in Abdominal Aortic Aneurysm (AAA) Size Per Year [ Time Frame: month 3, month 12 ]
    Size of the AAA was determined using an abdominal ultrasound technique at baseline, 3 months, and 12 months after treatment with study drug. Growth rate (in mm/year) was calculated from the change in AAA size compared to baseline

Enrollment: 65
Study Start Date: December 2013
Study Completion Date: October 2015
Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)

  4. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception during dosing and 30-day follow up period of the study.
  5. Donation or loss of 400 ml or more of blood within eight (8) weeks prior to initial dosing, or longer if required by local regulation.
  6. Subjects on the following medications: (a) Chronic systemic steroid treatment or other systemic immunosuppression; (b) Any biologic drugs targeting the immune system, along with a history of any previous use of such drugs.
  7. Presence of a non-healing wound or infection, including active urinary tract infections, or any recent process requiring significant tissue healing per investigator assessment.
  8. Significant illness which has not resolved within four (4) weeks prior to initial dosing or with a life expectancy less than 2 years.
