Conditions

  • Asthma
  • Perennial Allergic Rhinitis

Interventions

BIOLOGICAL

Cockroach Sublingual Immunotherapy (SLIT) - Low Dose

Participants are randomized to receive daily doses of glycerinated German cockroach (Blattella germanica) allergenic extract formulated in 50% glycerin at a concentration of 1:20 weight per volume \[w/v\] placed under the tongue (sublingual route) to dissolve. The treatment course and study duration was 3 months. Note: The extract was also administered during the preliminary dosing visits, up to three escalating doses, or until the maximum study dose (420 microliters, 1:20 w/v) was achieved.

OTHER

Placebo

Participants are randomized to receive either daily (low dose) or twice-daily (high dose) placebo treatment placed under the tongue (sublingual route) to dissolve. The treatment course and study duration was 3 months. Note: The placebo was also administered during the preliminary dosing visits, up to three or seven escalating doses, or until the maximum study dose (420 or 840 microliters, 1:20 weight per volume \[w/v\]) was achieved.

BIOLOGICAL

Cockroach Sublingual Immunotherapy (SLIT) - High Dose

Participants are randomized to receive twice-daily doses of glycerinated German cockroach (Blattella germanica) allergenic extract formulated in 50% glycerin at a concentration of 1:20 weight per volume \[w/v\] placed under the tongue (sublingual route) to dissolve. The treatment course and study duration was 3 months. Note: The extract was also administered during the preliminary dosing visits, up to seven escalating doses, or until the maximum study dose (840 microliters, 1:20 w/v) was achieved.
