Outsourced Data Integrity: Are Short-Term Financial Gains Worth Long-Term Headaches?

by and

Competitive pricing and continued cost pressures have contributed to the need for many US biopharmaceutical companies to outsource manufacture of active pharmaceutical ingredients (API) and finished products from countries with lower costs for labor, material, and equipment. The main benefit of doing so is lower costs of manufacturing with quality standards comparable to those found in the United States. India and China now account for 80% of API production. But those countries have received media attention because of biopharmaceutical manufacturing…

When Is a Virtual Business Model Suitable for Biopharmaceutical Companies?

by

Virtual companies are based on the model that all activities are outsourced. Such companies have no (or few) employees, occupy no laboratory space, and use contract service organizations for all activities. Over the past decade, several virtual biopharmaceutical companies have formed (1–4). They are primarily start-up ventures that use contract research organizations (CROs) for R&D and contract manufacturing organizations (CMOs) for product manufacturing. By contrast, a fully integrated biopharmaceutical company is based on the model that all activities are internal to…

Rapid Development and Scale-Up of Biosimilar Trastuzumab: A Case Study of Integrated Cell Line and Process Development

by , , and

Compared with that for new drugs, biosimilar development faces significantly condensed timelines from cell line to first-in-human (FIH) trials. A biosimilar development program needs to accelerate quickly toward preclinical and phase 1 studies; phase 2 studies typically are not required because dose response and other patient-treatment concepts are already established by the original, comparator medicine. Phase 3 studies typically are limited to fewer patients, which ultimately shortens overall timelines and costs. The key challenge remains: demonstrating comparability and high similarity…

Toward Industry Standardization of Extractables Testing for Single-Use Systems: A Collective BPSA Perspective

by

Here we present a consensus position of the membership of the Bio-Process Systems Alliance (BPSA), the trade organization for the single-use industry based in Washington, DC. BPSA’s membership includes 48 corporate and institutional entities, among them component suppliers, systems integrators, end users, and independent testing laboratories. Consensus within this membership is reached through an official ballot of representative voting members, as provided for in the organization’s by-laws. The position outlined below was approved by such an internal consensus-balloting process. Building…

Extractables Profiles: A Comprehensive Approach Produces Long-Term Results

by

Biopharmaceutical manufacturers spend years developing and testing new drug and biologic products to ensure their efficacy, safety, and usability for patients. Such knowledge is extremely valuable, but those same principles often get overlooked in selection of packaging and delivery systems. Decisions on packaging and delivery often are made almost as an afterthought. However, issues related to components such as extractables and leachables can affect patient safety and product quality. In addition, a lack of extractables and leachables data in filings…

Culturing a Duck ES-Derived Cell Line in Single-Use Bioreactors: A Rapid, Efficient, and Cost-Effective Vaccine Manufacturing System Based on Suspension Culture

by , , , , and

Cell substrates managed in controlled culture environments have become, over the past few decades, the subject of intensive technological developments for the biomanufacturing of viral vaccines. The driving force of such work is an expanding demand for safety, high production capacities, cost savings, and flexibility. Egg, tissue, and primary-cell–based manufacturing methods of limited capacity are now considered to be outdated technologies. In the influenza vaccine field, for example, time delays in vaccine delivery (especially during pandemic responses) have increased concerns…

The New Hybrid: Single-Use Systems Enabled By Process Automation

by

Much has been written in recent years about the union of single-use systems (SUS) and process automation. These two technology initiatives have been prevalent within biopharmaceutical manufacturing over the past decade and are two of the most predominant advancements in biomanufacturing. A basic survey of industry media and conference topics corroborates that premise (1). However, efforts to combine them remain in the early stages of technological fulfillment, with much work to be done in realizing their synergistic benefits. Here I…

Automation of a Single-Use Final Bulk Filtration Step: Enhancing Operational Flexibility and Facilitating Compliant, Right–First-Time Manufacturing

by and

Single-use technologies have been implemented in biomanufacturing facilities all over the world. Inherently more flexible than stainless steel equipment, single-use technology allows for more rapid technology transfer by minimizing the time it takes to design, purchase, and qualify new capital assets. Rapid turnover between batches is facilitated with no need for protracted clean-in-place (CIP) and steam-in-place (SIP) regimes; the risk of product cross contaminations is reduced because single-use fluid-contact surfaces are never previously exposed to a biopharmaceutical product stream. For…

Measuring Pressure at Very Low Levels with High Accuracy in Single-Use Systems: Improved Performance and Single-Use System Testing

by , , and

Measuring pressure in single-use systems (SUS) has become an integral part of both upstream and downstream bioprocess operations. Articles have been published on filtration applications (1), and integration into other SUS has been widely adopted. Additionally, information is available on low-pressure applications such as how to prevent overpressurization in single-use bioreactors (2). However, as users and applications both become more sophisticated, improved performance is sought for low-pressure applications (<1 psi) such as in single-use bioreactors. The reasons are two-fold: First,…

Implementing Flexible, Scalable, and Cost-Efficient Bioprocess Platforms: A Proven Project Management Approach

by and

Although significant scientific progress has been made in the biotechnology industry, it has lagged behind other sectors — such as aviation and automotive — in developing, scaling up, and industrializing products coming out of R&D. The goal is to implement robust and reliable manufacturing processes for good manufacturing practice (GMP) market supply cost-effectively. But manufacturing methods for biologics have remained unchanged for decades, with large-scale, capital-intensive stainless steel facilities taking three to five years to build and remaining both energy…
