Assessment
Primary outcomes Time to onset of IgE-dependent immediate reaction after starting the experimental diet
Key secondary outcomes 1.Secondary outcomes on effectiveness:
(1) Change in cumulative tolerated dose on formal registration day to at 24 and 48 weeks after starting the experimental diet
(2) Whether the oral challenge test of hen's egg is negative at 24 and 48 weeks after starting the experimental diet
(3) Change in total IgE value on temporary registration day to that at 24 and 48 weeks after starting the experimental diet
(4) Change in egg white- and ovomucoid-specific IgE value on temporary registration day to that at 24 and 48 weeks after starting the experimental diet
(5) Change in egg white- and ovomucoid-specific IgG4 value on temporary registration day to that at 24 and 48 weeks after starting the experimental diet
(6) Change in urinary PGDM (tetranor-PGDM, tetranor-PGEM) value 4 h after the intake of experimental diet on the starting day and at 4, 12, 24, 36, and 48 weeks
(7) Ratio of urinary PGDM (tetranor-PGDM, tetranor-PGEM) value before and 4 h after the intake of experimental diet on the starting day and at 4, 12, 24, 36, and 48 weeks
(8) Change in difference of urinary PGDM (tetranor-PGDM, tetranor-PGEM) value between before and 4 h after the intake of experimental diet on the starting day and at 4, 12, 24, 36, and 48 weeks
2.Secondary outcomes on safety:
(1) The maximum severity score of IgE-dependent immediate-type allergic reaction against hen's egg caused by experimental diet
(2) Number of symptom days related to IgE-dependent immediate-type allergic reaction against hen's egg
(3) Presence or absence of anaphylaxis related to the experimental diet
(4) Presence or absence of emergency room visits related to the experimental diet
(5) Number and proportion of participants who experienced severe adverse reactions at least once
(6) Number of participants who experienced severe adverse reactions, reaction appearance rate, and number of reactions

Interventions/Control_1 1.Very small amount at the starting method (The experimental therapy group)
-We set a cumulative tolerated dose of the hen's egg intake by oral challenge test on formal registration day.
-Patients take in the experimental diet including the hen's egg (egg white and yolk) of 1/50 quantity of the cumulative tolerated dose the day after the initiation for 4 weeks.
-Patients take in the experimental diet including the hen's egg of 1/10 quantity of the cumulative tolerated dose the day after from 4 to 8 weeks.
-Patients take in the experimental diet including the hen's egg of half quantity of the cumulative tolerated dose the day after from 8 to 12 weeks.
-Patients take in the experimental diet including the hen's egg of a cumulative tolerated dose the day after from 12 to 48 weeks.
Interventions/Control_2 2.Fixed-quantity maintenance method (Standard therapy group)
-We set a cumulative tolerated dose of the hen's egg intake by oral challenge test on formal registration day.
-Patients take in the experimental diet including the hen's egg of a cumulative tolerated dose every day until 48 weeks later.
