RESUMO
BACKGROUND: The novel intranasal formulation of azelastine hydrochloride (AZE) and fluticasone propionate (FP) in a single spray (MP-AzeFlu) was compared with a first-line intranasal antihistamine spray (AZE) in Russian seasonal allergic rhinitis (SAR) patients. METHODS: Moderate-to-severe SAR/rhinoconjunctivitis patients (n = 149; aged 18-65 years) were randomized to receive MP-AzeFlu (137/50 µg AZE/FP per spray) or AZE (137 µg/spray), both as 1 spray/nostril twice daily, in a multicenter, open-label, 14-day, parallel-group trial. The primary outcome was change from baseline in morning and evening reflective total nasal symptom score (rTNSS). Secondary end points included: change from baseline in reflective total ocular symptom score (rTOSS), reflective total of 7 symptom scores (rT7SS), 28-item Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) overall score, and EuroQol-5D (EQ-5D) questionnaire score. RESULTS: When compared with AZE-treated patients, those treated with MP-AzeFlu experienced significantly greater reductions in rTNSS (difference: -2.47; 95% confidence interval [CI] -3.65 to -1.30; p < 0.001), rTOSS (difference: -1.62; 95% CI -2.32 to -0.92; p < 0.001), and rT7SS (difference: -4.34; 95% CI -5.98 to -2.70; p < 0.001). Superior relief observed on day 2 with MP-AzeFlu versus AZE was sustained throughout the study. MP-AzeFlu-treated patients experienced a greater improvement in QoL than AZE-treated patients as measured by overall RQLQ score (mean ± SD 2.91 ± 1.08 vs. 2.05 ± 1.15) and EQ-5D score (mean ± SD 87.4 ± 10.3 vs. 83.0 ± 12.8). MP-AzeFlu was well tolerated. CONCLUSIONS: MP-AzeFlu was superior to AZE in reducing moderate-to-severe SAR symptoms, providing earlier and more complete symptom relief.

BACKGROUND: Patients with cystic fibrosis (CF) need costly medical care and adequate therapy with expensive medicinal products. Tigerase® is the first biosimilar of dornase alfa, developed by the lead Russian biotechnology company GENERIUM. The aim of the manuscript to present post hoc sub-analysis of patients' data with cystic fibrosis and severe pulmonary impairment of a larger comparative study (phase III open label, prospective, multi-centre, randomized study (NCT04468100)) of a generic version of recombinant human DNase Tigerase® to the only comparable drug, Pulmozyme®. METHODS: In the analyses included subgroup of 46 severe pulmonary impairment patients with baseline FEV1 level 40-60% of predicted (23 patients in each treatment group) out of 100 patients registered in the study phase III open label, prospective, multi-center, randomized study (NCT04468100), and compared efficacy endpoints (FEV1, FVC, number and time of exacerbations, body weight, St.George's Respiratory Questionnaire) as well as safety parameters (AEs, SAEs, anti-drug antibody) within 24 treatment weeks. RESULTS: All outcomes were comparable among the studied groups. In the efficacy dataset, the similar mean FEV1 and mean FVC changes for 24 weeks of both treatment groups were observed. The groups were also comparable in safety, all the secondary efficacy parameters and immunogenicity. CONCLUSIONS: The findings from this study support the clinical Tigerase® biosimilarity to Pulmozyme® administered in CF patients with severe impairment of pulmonary function.
