Rupatadine oral solution improves rhino-conjunctive symptoms control in children with 6-11 years weighing ≥25 kg with persistent allergic rhinitis
Clinical and Translational Allergyvolume 3, Article number: P33 (2013)
Clinical trials with the newer 2nd generation antihistamines in children under the age of 12 years have been performed previously but further studies are needed in order to show efficacy and safety in the most unfavourable clinical conditions such as persistent allergic rhinitis (PER). Rupatadine oral solution was developed for children with allergic rhinitis in view of its rapid onset of action and its lack of relevant side effects. These advantages were confirmed previously in a phase III study in children 6-11 years.
To assess the efficacy and safety of rupatadine (RUP) oral solution in a subgroup of children between 6 and 11 years weighing ≥25 kg with PER.
A subanalysis was performed from a previous placebo-controlled study carried out in patients between 6-11 years diagnosed as PER according to ARIA criteria. This analysis included patients with a positive prick test, weight ≥25 kg and basal nasal symptoms score (including rhinorrhea, nasal blockage, sneezing and nasal itching assessment) ≥24 obtained in 4 days throughout the 2-week screening period. Patients were allocated to treatment with either RUP oral solution (1 mg/ml) or placebo during 6 weeks. The dose was 5 ml of oral solution. The main efficacy endpoint was the change from baseline of the nasal (4TSS) and global symptoms (5TSS) score at 4 and 6 weeks of treatment. Furthermore the assessment of children's quality of life at 4, 6 weeks by means of PRQLQ was also evaluated.
The subgroup analysed was a total of 266 randomized to rupatadine (n=131) or placebo (n=135). Table 1 summarizes the efficacy results:
Rupatadine oral solution (1mg/ml) was significantly more effective than placebo in improving nasal symptoms (4TSS) at 4 and 6 weeks. This is the first clinical evidence of a H1-receptor antagonist efficacy in children between 6-11 years over 25 kg with PER.
