简要总结
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, phase IIb is a dose-ranging part and has been done, and phase III is a pivotal study part which is registered this time.
The goal of this phase III study is to evaluate the efficacy, safety, and pharmacokinetics of PG-011 nasal spray 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 if PG-011 nasal spray works to treat moderate to severe seasonal allergic rhinitis
详细描述
This is a multicenter, randomized, double-blind, placebo-controlled clinical study in adults participants aged from 18 to 65 years old (including threshold) with moderate to severe SAR. Approximately 600 participants will be randomized assigned to one of the 2 following groups in a 2:1 ratio.
PG-011 nasal spray 0.6% (1.2mg Pumecitinib) administered twice daily. PG-011 placebo nasal spray 0% (0 mg Pumecitinib) administered twice daily. Participants will receive blinded study treatment for 14 days followed by 21 days safety follow-up.

结局指标
主要结局
Change from baseline in average retrospective Total Nasal Symptom Score (rTNSS) over the 14-day treatment period
时间窗: Up to Day 14
The reflective Total Nasal Symptom Score (rTNSS) was assessed by 12-hour reflective scoring (AM, PM) of the severity of four nasal symptoms (rhinorrhea, sneezing, nasal congestion, nasal itching). Scores ranged from 0 (no signs/symptoms evident) to 3 (severe signs/symptoms that is hard to tolerate). The rTNSS was calculated as the sum of the subject-reported severity scores for nasal symptoms, and value ranged from 0 (no signs/symptoms evident) to 12 (severe signs/symptoms that is hard to tolerate). Higher scores indicate more severe nasal symptoms, while lower scores indicate less severe nasal symptoms.
