Primary Outcome Measures:
  • Efficacy: Intestinal mucosal morphology [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Intestinal mucosal morphology - change from baseline to week 6

  • Safety: Tolerability of ALV003 [ Time Frame: 6 weeks ] [ Designated as safety issue: Yes ]
    Safety will be evaluated by collection of adverse events, blood chemistry and blood cell counts


Secondary Outcome Measures:
  • Efficacy: Change in intestinal intraepithelial lymphocyte numbers/phenotype [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Intestinal intraepithelial lymphocyte numbers/phenotype - change from baseline to week 6

  • Efficacy: Change in serological markers of celiac disease [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    Serological markers of celiac disease - change from baseline to week 6


Enrollment: 61
Study Start Date: November 2010
Study Completion Date: June 2011
Primary Completion Date: May 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ALV003
ALV003 is an orally administered mixture of two recombinant proteases (cysteine endoprotease B-isoform 2 and prolyl endopeptidase) engineered to degrade gluten into non-immunogenic fragments, by targeting the glutamine and proline residues common in gluten.
Biological: ALV003
Placebo Comparator: Placebo
Excipients for ALV003 absent the experimental compounds
Biological: ALV003 placebo
