SECONDARY outcome

Timeframe: During months 6-12 after study agent adminsitration

Population: One subject in low dose group had AAT phenotype SZ, which made measurement of M-specific serum alpha-1 antitrypsin concentration invalid.

Results are the mean ± SD for pre-treatment (Screening and Baseline) and Months 6-12 values and mean ± SE for the difference between the pre-treatment and months 6-12 means for 2 subjects in the low dose group and 3 subjects in each of the other two groups. The monoclonal antibody used to determine serum M-specific AAT concentrations has very little cross-reactivity with Z type AAT but cross-reacts strongly with S type AAT, causing results for this assay to be spuriously high for subject 303 in the low dose group.
