43This is a single blind, dose escalating, placebo-controlled, crossover study of gluten-degrading drug PvP001 administered to healthy volunteers (age 18-64 years). Subjects will be randomized to one of three groups representing different levels of gluten exposure - low, medium, or high - in a single meal. Within each gluten exposure group, increasing doses of PvP001 (or placebo) will be administered.
Low-dose PvP001
Medium-dose PvP001
High-dose PvP001
100 mL liquid with no drug
This group will ingest the drug and then consume a study meal containing a low level of gluten. In four separate visits, each subject will be administered low-dose PvP001, medium-dose PvP001, high-dose PvP001 and placebo, with blinding to the dose of PvP001 and to which visit placebo is given.
This group will ingest the drug and then consume a study meal containing a medium level of gluten. In four separate visits, each subject will be administered low-dose PvP001, medium-dose PvP001, high-dose PvP001 and placebo, to the dose of PvP001 and to which visit placebo is given.
This group will ingest the drug and then consume a study meal containing a high level of gluten. In four separate visits, each subject will be administered low-dose PvP001, medium-dose PvP001, high-dose PvP001 and placebo, with blinding to the dose of PvP001 and to which visit placebo is given.
