Phase 1, First in Human (FIH), Open-Label, Single-Arm, Ascending Dose Study to Assess the Safety, Tolerability and Preliminary Immunogenicity of ITI-9001 in Japanese Patients With Japanese Red Cedar (JRC) Pollinosis
Japan45 participantsStarted 2026-06-20
Plain-language summary
This is a Phase 1, first-in-human clinical trial to test a new treatment called ITI-9001 for people with allergies to Japanese Red Cedar (JRC) pollen-a common cause of seasonal allergies in Japan. The main goals are to find out if ITI-9001 is safe, how well people tolerate it, and whether it can trigger helpful immune responses.

Inclusion criteria
. Signed and dated informed consent form (ICF)
. Female of non-childbearing potential or male aged 18-65 years (inclusive). Women are not considered to be of childbearing potential if they have had a hysterectomy or tubal ligation, or are postmenopausal (≥12 months without menstruation, or FSH in postmenopausal range for women \<55 years)
. Confirmed JCP sensitivity by positive skin prick test (wheal diameter ≥3 mm)
. Confirmed JCP sensitivity by ImmunoCAP (serum JCP-specific IgE ≥ class 2)
. ≥2 year history of seasonal rhinoconjunctivitis symptoms requiring medication upon JCP exposure
. Contraception requirements: \<br\> a. Women of non-childbearing potential: negative serum pregnancy test ≤3 days before first dose \<br\> b. Men: surgically sterile, or agree to abstinence or use 2 highly effective methods of contraception during study and for 3 months after last dose if partner is of childbearing potential (male condom + oral hormonal contraceptives, intrauterine device, or intrauterine hormone-releasing system)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
