From Big Data to Precise Understanding: The Quest for Meaningful Information

High-throughput technologies have transformed the biotechnology industry. The amount of data they generate is at least a hundred times higher now than it was two decades ago, primarily because of the rise of “-omic” technologies. As in many other industries, the biopharmaceutical sector entered the era of big data the day that high-throughput analytics were routinely implemented in experimental research. Big data refers to “datasets with sizes beyond the ability of commonly used software tools to capture, curate, manage, and…

Biopharmaceutical Product Specification Limits and Autocorrelated Data

Calculations, including statistical tolerance intervals, can assist in the development and revision of specification acceptance criteria. Manufacturing results for attributes of a biopharmaceutical product can be positively autocorrelated. The sample standard deviation — calculated from limited, positively autocorrelated data — tends to underestimate the long-term process standard deviation (1). In this article, simulated data are used to assess the relative performance of statistical tolerance intervals, intervals calculated using the minimum process performance index Ppk approach, and the sample range. Prevalence…

Bioprocess Development and Qualification: PAT-Based Stage 1 and 2 Acceleration Strategies

Well-established process analytical technology (PAT) strategies, such as those based on spectroscopy, bring with them several challenges related to the nature of those tools themselves (1–3). Such tools are multiparametric by design — in the sense that most spectroscopies capture multiple attributes sometimes different in nature (e.g., near-infrared, NIR, captures chemical and physical attributes simultaneously). Often a reference method is required; at other times, indirect calibrations are based on the correlation of one culture attribute with another for which a…

Ask the Expert: Highly Sensitive Host-Cell Protein Analyses Using Novel Chromatography Technology

Geert Van Raemdonck (global field support expert at PharmaFluidics) and Koen Sandra (scientific director of the Research Institution for Chromatography, RIC) teamed up for a 10 October 2019 “Ask the Expert” webinar to introduce micro Pillar Array Column (μPAC™) technology for liquid chromatography–mass spectrometry (LC–MS) for host-cell protein (HCP) detection. Van Raemdonck explained that μPAC technology approaches chromatography differently than does packed-bed technology. Microfluidic channels with arrays of free-standing pillars are etched lithographically into a silicon wafer. The resulting permeability…

Ask the Expert: Accelerating Timelines By Integrating Cell-Line Development and Manufacturing

In a 31 October 2019 “Ask the Expert” presentation, Nicole Wakes (group leader of Abzena’s cell-line development team) observed that drug sponsors often outsource their early upstream activities to a few different contract research organizations (CROs). But that strategy can thwart short timelines and introduce regulatory and financial risks. Wakes described Abzena’s upstream approach, illustrating how partnering with a single, multicompetent CRO from cell line construction through manufacture can streamline workflows. Integrating cell line development and manufacturing in this way…

Ask the Expert: Developing Bioprocesses for Clinical Manufacturing Success

Biopharmaceutical companies need to make critical chemistry, manufacturing, and controls (CMC) decisions during clinical development of recombinant protein biologics and advanced therapies. In a 17 December 2019 “Ask the Expert” webinar, Nigel Shipston (director of program design at FUJIFILM Diosynth Biotechnologies, FDB) reviewed key aspects of selecting and working with a contract development and manufacturing organization (CDMO). He also highlighted important factors that should be considered during early stages of process development. Shipston’s Presentation The sheer magnitude of investment required…

Ask the Expert: Cell Culture Media Analysis Using Handheld Raman Analyzers

In biopharmaceutical manufacturing, cell culture media supply critical nutrients and maintain pH and osmolality to optimize protein product yield. Because media composition and condition have a strong effect on final biologic product quality and production, biopharmaceutical companies monitor media for lot-to-lot variability. Stability testing for degradation due to light exposure, temperature changes, or shelf-life/time is possible with rapid spectroscopic methods. In an 8 October 2019 “Ask the Expert” webinar, O. Dean Stuart (product manager at Thermo Fisher Scientific) explained how…

Upstream: Make the Right Decisions for Your mAb

Bioprocess decisions made during upstream operations can be difficult to reverse at later, more costly stages of biologic manufacture. They even can require significant backtracking, wasting precious time, labor, and material. Read this Special Report to learn ways to optimize monoclonal antibody bioprocessing upstream. Specifically, you will learn about different tools that small and emerging biotechnology groups can use to ensure robust cell-line selection novel media formulations designed for intensified upstream processing in perfusion modes mixing and delivery solutions that…

Trends in Data Analytics As Organizations Undergo a Digital Transformation

The biopharmaceutical industry is in the midst of an exciting transformation as biologics experience massive growth — even outpacing the small-molecule segment (1). Biologics are predicted to comprise over a quarter of the pharmaceutical market in 2020 (2). At the same time, a plethora of new biologically derived therapy concepts — e.g., cell and gene therapies — are in development. Some biologics classes have become mainstream — e.g., monoclonal antibodies — with biosimilars entering the market and contract manufacturing organizations…

The Proof Is in the Data: Extractables and Leachables

Extractables and leachables (E&Ls) must be addressed in material and process validation programs. Extractables are compounds that can be extracted from a material in the presence of solvents with varying polarity under extreme conditions. Materials manufacturers should make extractables guides available to end users. Leachables are compounds that migrate from a material in the presence of an actual formulation under normal process operating conditions. Extractables information can be helpful as a basis for evaluation of potential process-equipment–related leachables (PERLs)testing. However,…
