MedImmune LLC Identifier:
First received: September 8, 2009
Last updated: September 9, 2009
Last verified: September 2009
This study includes subjects with asthma to participate in one of three groups and randomly assigned to a group to receive the drug for the study (CAT-354) or placebo.

Condition Intervention Phase
Drug: CAT-354-0602
Drug: Placebo
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Double-Blind, Placebo Controlled Study to Assess the Pharmacokinetics, Safety and Tolerability of Multiple Intravenous Doses of 3 Dose Levels of CAT-354 in Subjects With Moderate Asthma

Further study details as provided by MedImmune LLC:

Primary Outcome Measures:
  • Pharmacokinetics Assessment: Individual serum concentration profiles for CAT-354 will be generated for each subject. [ Time Frame: Day 162 ]

Secondary Outcome Measures:
  • Safety and Tolerability Analysis based on safety population. (e.g., vital signs, lung function, ECG results, haematology, chemistry and normal ranges) [ Time Frame: Day 162 ]

Enrollment: 30
Study Start Date: September 2006
Study Completion Date: October 2007
Primary Completion Date: September 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CAT-354-0602
Drug: CAT-354-0602
1, 5 and 10 mg/kg - Day 0,28, and 56
Placebo (saline)
Drug: Placebo
1,5, and 10 kg - Day 0, 28, and 56

Detailed Description:
This study is a randomised, double-blind, placebo controlled study. Following confirmation of eligibility, subjects with moderate asthma will be recruited sequentially to one of three dose groups and randomly assigned within dose group to either CAT-354 or placebo. Doses of the assigned treatment will be administered on three occasions 28 days apart. Follow up for pharmacokinetic blood sampling and safety will continue to Day 147 post first dose (91 days post third dose).

  • 18-60 years
  • GP diagnosis of asthma of 1 year's min. duration (with respect to Day 0)
  • No significant abnormality on clinical examination or medical history (excluding atopic skin signs, symptoms and history)

  • Treatment of atopic symptoms, other than eczema, within 4 weeks of Day 0
  • History of medication that might carry-over effects into the study
  • Previously received monoclonal antibody, or a similar related protein, that might sensitise to CAT-354
  • Participation in another study within three months of the start of the study or 5 half lives of the previously administered investigational medicinal product (IMMP), whichever is longer
