Onset-of-Efficacy of Azelastine HCl 0.15% Nasal Spray for allergic rhinitis in an environmental exposure chamber.

BACKGROUND: Azelastine nasal spray is effective in relieving symptoms of seasonal and perennial allergic rhinitis. OBJECTIVE: The objective of this single center, double-blinded, placebo-controlled, crossover study was to evaluate the time to onset of efficacy of azelastine HCl 0.15% vs placebo in participants with seasonal allergic rhinitis. METHODS: 110 participants aged 18 to 65 years were randomized to receive azelastine HCl 0.15% two sprays per nostril vs placebo nasal spray after being continuously exposed to ragweed pollen in an environmental exposure chamber (EEC). Symptoms were evaluated subjectively by the total nasal symptom score (TNSS) scale. The primary efficacy parameter was the time to onset of efficacy of azelastine as measured by the change from baseline in TNSS 15, 30, 45, 60, 90, 120, 180, and 240-minute post-dose. RESULTS: The azelastine nasal spray group had statistically significant improvement in TNSS compared with placebo 30 minutes post-dose (p=0.0002), and the effect was sustainable throughout the EEC session for all subsequent time points (p<0.0001). Adverse events were mild, including bitter taste, nasal discomfort, epistaxis, sinusitis, and nausea. No major adverse events were reported during the study. CONCLUSION: Azelastine HCl 0.15% nasal spray relieves nasal symptoms associated with allergic rhinitis and has a fast onset of action within 30 minutes. The overall safety profile of azelastine has also been proven to be safe. These results, along with prior findings on efficacy and improved quality of life for people suffering from allergic rhinitis, establish the important clinical role of azelastine HCl 0.15%.

Multi-omic analysis of dysregulated pathways in triple negative breast cancer.

The aggressive characteristics of triple-negative breast cancer (TNBC) and the absence of targeted medicines make TNBC a challenging clinical case. The molecular landscape of TNBC has been well-understood thanks to recent developments in multi-omic analysis, which have also revealed dysregulated pathways and possible treatment targets. This review summarizes the utilization of multi-omic approaches in elucidating TNBC's complex biology and therapeutic avenues. Dysregulated pathways including cell cycle progression, immunological modulation, and DNA damage response have been uncovered in TNBC by multi-omic investigations that integrate genomes, transcriptomics, proteomics, and metabolomics data. Methods like this pave the door for the discovery of new therapeutic targets, such as the EGFR, PARP, and mTOR pathways, which in turn direct the creation of more precise treatments. Recent developments in TNBC treatment strategies, including immunotherapy, PARP inhibitors, and antibody-drug conjugates, show promise in clinical trials. Emerging biomarkers like MUC1, YB-1, and immune-related markers offer insights into personalized treatment approaches and prognosis prediction. Despite the strengths of multi-omic analysis in offering a more comprehensive view and personalized treatment strategies, challenges exist. Large sample sizes and ensuring high-quality data remain crucial for reliable findings. Multi-omic analysis has revolutionized TNBC research, shedding light on dysregulated pathways, potential targets, and emerging biomarkers. Continued research efforts are imperative to translate these insights into improved outcomes for TNBC patients.
