Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study consists of 2 parts: Part 1 and Part 2. \[Part 1\] An open-label, un-controlled study Examine the safety for the ASP4070 intramuscular vaccination group (high dose x 4 times) and the ASP4070 intradermal vaccination group (high dose x 4 times).

\[Part 2\] A placebo-controlled, double-blinded, randomized, parallel-group comparative study Assess the immunological response and safety for the ASP 4070 intramuscular vaccination group (high dose x 1 time and high dose x 4 times) and the ASP4070 intradermal vaccination group (low dose x 1 time, low x 4 times, high dose x 1 time, and high dose x 4 times) as compared to those for the placebo group. The study will be double-blinded within the same route of vaccination, and non-blinded between the routes of vaccination (between the intramuscular vaccination group and intradermal vaccination group).

The first vaccination to the subjects in Part 2 will start at least 14 days after the first vaccination to the subjects in Part 1 (6 subjects).

For both Part 1 and Part 2, primary study period is for 3 months starting from the last dose of the study drug at Day 43 (until Day 127). After the primary study period, safety information will be collected for 9 months (for 1 year from the last dose of the study drug) as the long-term safety follow-up study period. Safety information will be collected for 1 year starting from the last vaccination of the study drug also from the patients who discontinued the participation in the study during the primary study period if the patients agree.

* Subject who had a positive prick test result for Japanese cedar pollen in the screening test.
* Subject whose past and present medical conditions are considered medically stable.

Exclusion Criteria

* Subject who had the test result of IgE antibody specific to other antigen than Japanese cedar pollen
* Subject who is scheduled to receive other vaccination during the primary study period.
* Subject who has received or is planning to receive vaccination of live vaccine within 28 days prior to the first vaccination of the study drug, and/or a subject who has received or is planning to receive vaccination of inactivated vaccine/toxoid within 7 days prior to the first vaccination of the study drug.
