Brief Summary:
A phase 2a study to evaluate the safety and efficacy of ALV003 to treat celiac disease.

Condition or disease Intervention/treatment Phase
Celiac Disease Biological: ALV003 Biological: ALV003 placebo Phase 2

Detailed Description:
Double-blind, placebo controlled study of the efficacy, safety and tolerability of 6-weeks treatment of ALV003 in patients with well-controlled celiac disease. Approximately 110 biopsy proven celiac disease patients will be randomized to treatment with ALV003 or placebo in a 1:1 ratio. Patients will be required to have a pre-dose and a post-treatment intestinal biopsy, and also will be required to ingest a foodstuff that contains a specified amount of gluten during the active phase of the study along with the study treatment. Patients will return to the clinic weekly for the first two weeks, then every two weeks thereafter for safety visits. Patients will return to the clinic 28 days after completion of treatment for final safety and follow-up. Safety will be closely monitored throughout the study including laboratory parameters and clinical assessment of adverse events.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
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
ALV003 is an orally administered mixture of two enzymes (cysteine endoprotease B-isoform 2 and prolyl endopeptidase).
Placebo Comparator: Placebo comparator
Excipients for ALV003 absent the experimental compounds
 Biological: ALV003 placebo
ALV003 is an orally administered mixture of two enzymes (cysteine endoprotease B-isoform 2 and prolyl endopeptidase).
