Regulatory framework for development and marketing authorization of allergen products for diagnosis of rare type I and type IV allergies: The current status

Development, production, and marketing authorization of allergen products is generally challenging due to several specific characteristics, including the natural source as well as the multitude of allergenic materials.

Also, depending on the frequency of sensitization in the population, the number of patients available for inclusion in clinical trials can be a limiting factor for product development.

In the development of allergen products for diagnosis of type I and type IV allergies these challenges are particularly demanding because, in contrast to certain products for allergen-specific immunotherapy, no exemptions from marketing authorization are foreseen for this product group in Directive 2001/83/EC.

Thus, the regulatory framework is constantly adapted within the legal scope in order to balance necessary regulatory requirements ensuring quality, safety, and efficacy with the clinical need for a comprehensive range of diagnostic allergen products.

In this article, we give an overview on the current regulatory framework for development and marketing authorization of allergen products for diagnosis of rare type I and type IV allergies.
