SECONDARY outcome

Timeframe: Baseline through 6-months of treatment

Population: Intent-to-treat

Outcome is the ratio of geometric means for baseline German cockroach-specific serum Immunoglobulin E (IgE) vs. post-baseline German cockroach-specific serum IgE. Numerator is geometric mean post-baseline IgE; denominator is baseline IgE. This result is an indicator of immune modulation over time, however its clinical significance is unclear.

Population: Intent-to-treat

Outcome is the ratio of geometric means for baseline German cockroach-specific serum Immunoglobulin G (IgG) vs. post-baseline German cockroach-specific serum IgG. Numerator is geometric mean post-baseline IgG; denominator is baseline IgG.This result is an indicator of immune modulation over time, however its clinical significance is unclear.

SECONDARY outcome

Timeframe: Baseline through 6-months of treatment

Population: Intent-to-treat

Outcome is the change in mean IgE fragment antibody binding (FAB) activity, baseline to post-baseline. Serum from cockroach subcutaneous immunotherapy (SCIT)-treated participants were analyzed to determine if treatment inhibits the in-vitro cockroach antigen binding to B-cells after 6-months of treatment with cockroach SCIT, using the per protocol allergenic extract doses. This result is an indicator of immune modulation over time, however its clinical significance is unclear.
