A Non-inferiority Randomized Controlled Trial of Topical Bisaitong (鼻塞通) in Treatment of Moderate to Severe Allergic Rhinitis
(鼻塞通) in treating moderate-to-severe allergic rhinitis (AR).
Methods
2
A randomized, positive-controlled, non-inferiority clinical trial design was adopted. Totally, 108 cases of moderate-to-severe AR were randomly divided into
Bisaitong
group and mometasone furoate group,with 54 cases in each group. The
Bisaitong
group was treated with
Bisaitong
smeared at the nasal cavity twice a day
,
and the mometasone furoate group received inhalation of mometasone furoate nasal spray 100 μg in each nostril, once a day. Both groups were treated for 4 weeks and followed up after additional 4 weeks. Both groups were compared on the rhinoconjunctivitis quality of life questionnaire (RQLQ), rhinoconjunctivitis total symptom score (RTSS), visual analogue score (VAS) of sneezing, runny nose, nasal itching, nasal congestion degree, days of AR episodes at enrollment, after 2- and 4-week, and at follow-up. The peripheral blood eosinophil (EOS) count and percentage (EOS%), serum eosinophil cationic protein (ECP), serum dust mite, dermatophagoides farinae, and cockroach allergen-specific IgE (sIgE) levels were compared between groups at enrollment and after 4-week treatment. Drug overuse rate was calculated, and the safety was evaluated. The analysis of all efficacy outcomes was based on both full analysis set (FAS) and per-protocol set (PPS).
Results
2
The lower limit of the 95% confidence interval for the differences in RQLQ scores were greater than -0.6 measured after 2- and 4-week treatment and at follow-up compared to that measured at the enrollment in both groups, indicating of the
Bisaitong
group being non-inferior to the mometasone furoate group. There was no statistically significant difference between groups on RTSS score, VAS scores of sneezing, runny nose, nasal itching, nasal congestion degree and days of episodes at all timepoints (
P
>0.05), but each outcome changed significantly over time in both groups (
P
<0.01). The differences between groups in EOS count, EOS%, ECP levels, serum dust mite, dermatophagoides farinae, cockroach sIgE levels, and drug overuse rate were not statistically significant at enrollment and after 4-week treatment (
P
>0.05). Adverse events occurred in eight cases (15.10%) in the
Bisaitong
group and five cases (9.30%) in the mometasone furoate group, showing no significant difference between groups (
P
>0.05).
Conclusion
2
Topical
Bisaitong
is non-inferior to mometasone furoate nasal spray in the treatment of moderate to severe AR in terms of clinical symptom relief,reduction in the episodes, improvement of quality of life, and sound safety.
