Biologics Analysis

Analytical Methods for Biologics

Over the past few decades, the healthcare landscape has undergone a massive shift towards biopharmaceutical drugs. Biologics now represent a major class of modern therapeutics and their share continues to increase relative to traditional small molecule drugs. Despite this growth, the significant costs associated with efficiently discovering biological materials and developing them at a commercial scale can limit R&D efforts. This is particularly true for companies that lack the capacity and know-how to develop and execute the necessary analytical methods for biologics in-house.

This is just one of the reasons why Avomeen is an invaluable partner for biologics analysis. Along with access to our purposefully equipped labs, our team has significant expertise in all stages of biologics R&D; from early discovery through IND, BLA, and beyond. For each unique project, our team brings a combination of in-house protein biochemistry, molecular biology, cellular biology, and QC experience. This enables rapid design and development of robust cellular potency or in vitro efficacy methods to help obtain the pivotal data necessary for regulatory submissions and release testing. In partnership with our clients, we work to accelerate R&D efficiency and breakdown roadblocks when they need us most.

Our Biologics Analysis

Peptides – With properties that land somewhere between small molecules and proteins, peptides have a long history in human medicine. They also have their own bioanalytical challenges, particularly bioavailability and peptide stability. Avomeen understands the unique challenges associated with determining peptide purity and potency and can help you investigate your molecules stability through forced degradation studies.

Proteins & Enzymes – Proteins and enzymes can be used for an incredibly diverse set of therapeutic functions, from replacement therapies to diagnostics. Avomeen offers standard analytical services such like extra characterization, forced degradation studies, peptide map analysis, product-related and process-related purity analyses, specific activity, in vitro cellular uptake method development/validation, and more!

Monoclonal Antibodies (mAbs) – Monoclonal antibodies represent the fastest growing class of protein therapeutics. Given their clinical (and economic) significance, Avomeen has devoted special resources and techniques to mAb bioanalytical testing.

Gene Therapy & AAV Vectors – Biotechnological advancements in the past two decades have made room for safer and more effective gene therapies, many of which use adeno-associated viruses (AAV) as viral vectors. However, determining viral vector purity and transduction efficiency remains a significant analytical challenge for many innovators. Here, Avomeen can help companies develop the right method for each unique AAV product using our Protein Simple capillary electrophoresis system, UPLC capabilities, and cell culture facility; all while keeping clinical safety at the forefront.

Biosimilars As biopharmaceutics continue to grow in emphasis and importance, an increasing number of FDA-approved innovator biologics’ patents will expire. As a result, biosimilar development will expand significantly. While these materials can reach the market rapidly, there are challenges associated with proving the similarity of these new product to the originally approved innovator drug. Avomeen understands the emerging potential biosimilar development holds and knows how to efficiently compare biologics to determine similarity. If you’re interested in partnering on biosimilar development, speak to Avomeen to find out more about our capabilities.
