PRIMARY outcome
Timeframe: 9-12 monthsPopulation: The study was prematurely terminated due to difficulties in meeting enrollment goals due to the Coronavirus Disease 2019 (COVID-19) pandemic. As a consequence, all prespecified efficacy endpoint analysis were not performed, and the exit DBPCFC was optional and limited to subjects who completed at least 9 months of study treatment including at least 4 weeks at 300 mg/day, and tolerated the 300 mg/day dose for approximately 2 consecutive weeks before the exit DBPCFC.
Outcome measures
| Measure |
AR201 Powder
n=9 Participants
Study product provided as dried egg white in pull-apart capsules.
AR201 powder in capsules: AR201 powder (Hen Egg allergen formulation) formulated to contain dried egg white at different dosage strengths.
|
Placebo Powder
n=6 Participants
Placebo formulation in pull-apart capsules containing only inactive ingredients
Placebo powder provided in capsules: Placebo powder formulated to match the color and texture of dried egg white.
