Clinical Trials Update

Current Clinical Developments

As of 2023, azelastine remains a focal point in ongoing clinical research, particularly in optimizing formulations, expanding indications, and enhancing delivery mechanisms.

1. Formulation Innovations: Recent trials investigate enhanced bioavailability and reduced dosing frequency through novel delivery systems. For instance, intranasal emulsion and spray formulations aim to improve patient compliance and efficacy. These are largely in phase II and III stages, with some candidates expected to reach approval within the next 12-24 months.

2. Expanded Indications: Although primarily indicated for allergic rhinitis and conjunctivitis, trials are exploring off-label uses such as chronic cough management and atopic dermatitis. Early data suggests potential benefits, though regulatory approval remains pending.

3. Combination Therapies: Several ongoing studies assess azelastine in combination with corticosteroids, aiming to improve symptom control in severe allergic conditions. These trials are in phases II and III, with promising preliminary results indicating enhanced efficacy over monotherapy.

Regulatory and Approval Status

• Approved Markets: Azelastine nasal spray (ASTELIN) is approved in the US, EU, and Asia-Pacific regions, with approval timelines varying by country.
• New Approvals & regulatory filings: Regulatory submissions for novel formulations and expanded indications are underway in Europe and Asia, aiming for approval from agencies like EMA and Japan's PMDA.
• Post-Marketing Surveillance: Ongoing pharmacovigilance aligns with regulatory requirements, monitoring safety profiles in diverse patient populations.
