Across the biosafety and regulatory landscape

BioReliance® analytical development services

Analytical Development

Orthogonal approaches to product characterization support better understanding of an asset's performance, safety, and the manufacturing processes for Drug Substance (DS) and Drug Product (DP).

Identity, purity, strength, and potency should be considered collectively to inform the best decisions about: Where and how to act, setting specifications, and understanding performance.

A subset of approaches should move into Analytical Development to formalize assays to support testing under GMP required for Critical Quality Attributes (CQAs) defined by ICH Q6B.

It is important to recognize that all modalities and processes are different, but the attributes defining quality are consistent and must be understood and monitored.

With ADCs, it is important to look beyond drug-to-antibody ratio (DAR). Understanding how post- translational modifications and conjugation may affect binding and potency is an important consideration that affects internalization and ultimately, potency.

How well do you understand the structure-function relationship with your molecule? With mAbs, it is important to understand binding performance, covalent modifications (post translational modifications and/or unintentional modifications) and how those factors affect performance.

Given the unique characteristics of the mRNA/LNP complex, new expertise and a series of novel analytical capabilities are required to ensure fast, efficacious, and compliant mRNA-based vaccines and therapeutics. We provide testing services for mRNA starting materials, drug substance, and drug product.

Cell & Gene Therapy

AAV therapies are complex and present unique challenges to monitor quality and performance. These activities require careful planning and management of orthogonal techniques (e.g., analytical, structural, and molecular). Breadth of capabilities and coordination are key to success.
