Inhaled and Nasal Biologic Drug Development and Testing
Inhaled and nasal biologic drug development support through formulation development, testing, characterisation, stability, performance/release testing and clinical manufacturing capabilities
Inhaled and nasal biologic drug development offers a highly attractive administration route for various classes of biologics or large molecule therapeutics, particularly for the treatment of respiratory diseases.
The potential for new therapeutic pathways for diseases such as cystic fibrosis, asthma and lung cancer, coupled with the advantages presented by targeted delivery to the lung (and systemic delivery for other diseases or treatment pathways), are driving this increased attention across the pharmaceutical industry.
The complexity of biologics and the difficulty of delivering a drug to the lungs and the nose means that inhaled and nasal biologic drug development is particularly challenging. In regulatory terms, these products will require characterisation of the biologic as per ICH Q6B, as well as specific OINDP testing to assess delivered dose uniformity from the device and the particle size of the drug emitted as outlined in documents such as the EMA guideline on the pharmaceutical quality of inhalation and nasal products (June 2006) or the US FDA metered dose inhaler (MDI) and dry powder inhaler (DPI) products quality considerations guidance (April 2018).
Biologic drugs have complex structures including higher order structures fundamental to their function, safety and efficacy and are susceptible to a wide range of degradation routes such as aggregation, fragmentation, deamidation, hydrolysis, oxidation, deglycosylation and disulphide bond formation/ breakage. Sophisticated formulation development and device selection are key to avoiding these pathways and developing a stable, efficacious product. In parallel, a wide suite of robust biologics characterisation tools is essential.
Intertek has over 30 years’ experience in biologics characterisation, from small peptides up to monoclonal antibodies and conjugated species, and contract testing, formulation and clinical manufacturing services supporting orally inhaled and nasal drug product development. The Intertek Centre of Excellence for Inhaled Biologics deploys a strategic programme of orthogonal analytical methods which aim to both fully characterise the biological entity and establish whether the device delivery mechanism (e.g. actuation through an inhaler) has adversely affected parameters. This includes the requirements of the ICH Q6B Guidance such as potency, protein structure characterisation and confirmation, total protein quantity, key physicochemical properties, post-translational modifications (PTM), higher order structure, assessment of aggregation, product-related impurities and process-related residuals.
With integrated formulation and stability teams, we use stability data to drive insight into the impact of the formulation and the device on the biologic including developing and validating stability-indicating methods and forced degradation studies. We have experience across nasal solutions / suspensions, nebulised solutions / suspensions and dry powders, offering a Center of Excellence to support you with formulation development, product performance testing, method development/validation, stability, CMC support and clinical manufacturing capabilities.
We have over 25 years of experience in supporting clients’ orally inhaled & nasal drug product development, from early-stage development, through to in-process control and product release assays. With a heritage of supporting advanced pharmaceutical product development and formulation, coupled with a comprehensive range of analytical technology, our experts offer Total Quality Assurance expertise to help you ensure the safety, efficacy and quality of your inhaled or nasal biologic product.
