Single-Use Systems: Globalization Best Practices and Technology Specifications

The challenges of multi-national bioprocessing operations are numerous. They include finding highly skilled experts for each site, lack of expertise with single-use systems, contamination risks and redundant efforts and resources—all of which can lead to higher costs. But these challenges also present opportunities for increasing speed to market, eliminating redundant work and overall cost savings. This white paper details the best practices used in global drug manufacturing. The key is global coordination. Best practices and specifications need to be identified…

A Strategy to Remove Formulation Development from the Critical Path During Biologics Development

Biopharmaceuticals tend to be highly unstable. Therefore, as the product development program progresses to phase 3 clinical stage, formulation development is required to ensure drug product quality and stability during manufacturing, storage and clinical administration. Also, formulation development is often on the critical path to successful IND and BLA fillings. During this Q&A, Dr. Jun Lu, Director, Analytical Development, discusses how Catalent Biologics utilizes automation, specifically the Uncle platform, during formulation development.

High-Viscosity Mixing: Choosing the Right System for the Job

Manufacturers of topical ointments, gels and lotions for BioPharma, personal care and other high-viscosity products face critical product quality challenges in their mixing processes. The better these challenges are understood, the more specific the design and configuration of processing equipment can be, to optimize product quality and maximize plant productivity. Unfortunately, conventional mixing systems may limit the ability of product manufacturers to optimize productivity and efficiency. The inefficiency of conventional dual-agitated vessels, multiple mixing vessels, and the operational complexity of…

Understanding Critical Measurement Parameters in Vaporized Hydrogen Peroxide Bio-decontamination

Effective destruction of microorganisms can be achieved with vaporized hydrogen peroxide, a safe and effective bio-decontamination method in many applications, including medical device manufacturing and healthcare procedure room decontamination. However, to ensure efficacy, it is necessary to monitor the level of hydrogen peroxide during the bio-decontamination. Measurement parameters are interdependent; temperature affects humidity, as does H2O2 concentration. These in turn will determine the point in time that condensation will occur, a critical phase. Some manufacturers of bio-decontamination chambers or isolators…

Characterization and Lot Release Assays for Antibody Drug Conjugates

Antibody-drug conjugates (ADCs) add an additional level of challenge to testing of biotherapeutics. Besides the antibody, which needs to be evaluated for potential and known mechanisms of action (MoA), there is a cytostatic compound conjugated that alters the behavior of the antibody-vehicle within the typical assays. Therefore, characterization of new innovators as well as biosimilarity assessment is even more challenging than it is for antibody therapeutics. Using the example of Trastuzumab emtansine, Charles River has set up a panel of…

Keeping Host Cell Protein ELISAs Covered

Biological drugs (or biologics) are manufactured by living systems such as microorganisms, and plant and animal cells. Cell lines, like Chinese hamster ovary (CHO), can be engineered to work as cellular factories to produce biologics in addition to their own biological molecules. Host cell proteins (HCPs) are biological by-products of these cellular factories. They are one of the main impurities in harvested cell culture fluid (HCCF), and tend to be released when the cells die or are damaged. These HCPs…

Flow Cytometry News: Does your lab comply with 21 CFR Part 11?

21 CFR Part 11 refers to the section in the Code of Federal Regulations (CFR) that sets forth the United States Food and Drug Administration’s (FDA) guidelines on using electronic records and electronic signatures. Chapter 21 covers all regulations pertaining to GCP (Good Clinical Practice), GLP (Good Laboratory Practice) and GMP (Good Manufacturing Practice), relating to the pharmaceutical and healthcare industries. Part 11 covers all FDA regulated issues pertaining to electronic records and electronic signatures. All computer systems that store…

The Challenge of Building Better, Lower Cost Biologic Drugs Faster

A critical factor for both the lowering in costs of development as well as costs of production for biologic therapies is to develop a cell line that grows faster and produces larger amounts of vaccines and drugs using low cost synthetically defined media. Dyadic’s industrially proven C1 gene expression platform creates a stable cell line in a shortened timeline, reducing the time from gene fragment to stable cell line by 50% when compared to CHO cells. C1 stable cell lines…

Culture of 3D Cell Aggregates in Perfusion in a DASbox® Mini Bioreactor System

Three-dimensional (3D) cell aggregates are of great interest for many applications, including disease modeling, drug toxicity assessment, and manufacturing of stem cell-based products. Stirred-tank bioreactors are promising culture systems for 3D cell aggregates, as they allow efficient establishment and maintenance of cell aggregates, process monitoring and control, and process scale-up to larger volumes. Furthermore, they can be operated in perfusion mode, which allows 3D cell aggregates to be sustained longer than in traditional batch cultures. Researchers at the Instituto de…

Optimizing Unit Operations In Biopharmaceutical Manufacturing

There are many critical material-handling challenges regarding flow rates, pressure levels and the prevention of shear in the chromatography, virus filtration and TFF processes that are used in the manufacture of biopharmaceuticals. In order for these unique operations to be implemented successfully while handling fluids that can be sensitive, delicate and expensive, the operator must be aware of their specific operating characteristics and choose a pumping technology that can meet the strict demands for successful operation. While lobe and peristaltic…
