A Study to Assess the Efficacy and Safety of PG-011 Nasal Spray in Adults With Moderate to Severe Seasonal Allergic Rhinitis
China160 participantsStarted 2025-03-12
Plain-language summary
The study is a multicenter, randomized, double-blind, placebo-controlled seamless and adaptive-designed phase IIb/III study encompassing a phase IIb and a phase III component. The phase IIb study, which is registered this time, is a dose-ranging component. The phase III study is a pivotal part of the overall research.
The goal of this phase IIb study is to evaluate the efficacy, safety, and pharmacokinetics of PG-011 nasal spray across various dosages and administration frequencies for treating adults with moderate to severe seasonal allergic rhinitis (SAR). Investigators will compare PG-011 nasal spray to a placebo (a look-alike substance that contains no drug) to see which dosage and frequency works to treat moderate to severe seasonal allergic rhinitis.

Inclusion criteria
. Male or female aged 18 to 65 (including threshold).
. Reflective total nasal symptom score ( rTNSS) score≥ 6 and retrospective nasal obstruction ≥ 2 on the day of screening visit, D-4 and D1. Meanwhile, the baseline average rTNSS score(Calculated as the average of rTNSS score of D-3, D-2, D-1 morning, D-1 evening, and D1 morning) ≥ 6
. History of SAR for at least 2 years. and positive results for any local allergen in the current season tested by either the skin prick test (SPT) (where the wheal diameter is at least 5 mm larger than that of the negative control) or the serum - specific IgE (sIgE) test (the sIgE test results obtained within ≤ 1 year before random enrollment are acceptable).
. Willingness to avoid pregnancy or fathering children from the signing of the informed consent form until one month after the last administration of the investigational medicinal product.
. Willing to sign the informed consent form and abide by the research protocol.
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?

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.
What they're measuring
1
Change from baseline in average retrospective Total Nasal Symptom Score (rTNSS) over the 14-day treatment period
. Participants are diagnosed of active or latent tuberculosis infection.
. Participants are diagnosed of moderate to severe asthma.
. Participants who had active pulmonary diseases or infections (including but not limited to bronchitis, pneumonia), upper respiratory tract infections or sinus infections within 4 weeks before screening, and/or those who had respiratory infections during the lead-in period.
. Participants received nasal or sinus surgery within 3 months before screening or had nasal trauma that had not fully healed.
. Any nasal mucosal erosion, nasal septal ulcer, nasal septal perforation or other nasal diseases that, as judged by the investigator, may affect the deposition of drugs in the intranasal, such as acute or chronic sinusitis, drug-induced rhinitis, nasal polyps, etc.
. Participants has ocular herpes simplex or other ocular infections (except seasonal allergic conjunctivitis).
. Participants with facial or systemic fungal, bacterial, viral or parasitic infections, or oral infections that had not been cured and still required continuous treatment within 4 weeks before screening.
. Participants have severe diseases such as central nervous system, respiratory system, liver, kidney, gastrointestinal tract, urinary system, endocrine system or blood system, which may affect the judgment of efficacy and safety .
