A Single-Use, Clinical-Scale Filling System: From Design to Delivery

by , and

Single-use components have been successfully incorporated into many unit operations for both upstream and downstream processing, from laboratory scale to commercial manufacturing. The development of single-use filling needles has created an opportunity to introduce fully disposable systems into final formulation and filling of drug products (1). One major challenge in replacing a cleanable filling line containing stainless steel needles is to ensure that an alternative system can satisfy all critical performance parameters established for an existing process. In 2012, Merck…

Single-Use Technology Enables Flexible Factories

by and

The biosimilars market is rapidly evolving, with more than 450 biosimilar molecules in development worldwide, and many anticipated transfers of molecules in process around the globe. With US$85 billion of biopharmaceutical products coming off patent by 2020 (1), the driving force to develop biosimilars is strong. The market will be highly saturated, with dozens of biosimilars currently in development for each current blockbuster molecule. We know of 46 trastuzumab biosimilars and 39 rituximab biosimilars in development. Because the biosimilars market…

Outsourcing to Enhance Assurance of Supply: Application of Counterintuitive Supply Chain Strategies — A Case Study

by , , , and

Single-use technologies have transformed biopharmaceutical manufacturing by providing tremendous and proven opportunities to reduce costs, improve flexibility, and shorten cycle times. The expansion of such technologies into commercial production has naturally raised new challenges for both end users and suppliers, thus driving the need for a critical look at risks associated with their use. End users now face a new challenge: how to assess their own supply chains for robust assurance of supply. What is the suppliers’ responsibility in addressing…

Bioprocessing Standards for Single-Use Components Are Moving Forward

by

With the escalating use of single-use technology in bioprocessing, suppliers have had to rapidly develop disposable components such as fittings, tubing, pumps, sensors, and flexible containers for bioprocessing. Single-use technology is growing so fast that the organizations tasked with guiding its growth are having difficulty keeping up. Contributing to this problem are factors such as company needs, regulatory requirements, market pressures, and costs. That growth has posed considerable concerns for the bioprocessing industry about the presence of organic and inorganic…

The Global Emergence of Single Use

by

Adoption of single-use manufacturing continues to expand globally and is showing no signs of slowing down. And why should it? The biopharmaceutical industry is challenged to produce safe, effective therapies and vaccines amid the constant pressure to lower cost per dose in addressing healthcare needs of not only the western hemisphere, but emerging markets as well. To meet these challenges, manufacturers are turning to single-use and hybrid systems that incorporate a balance of stainless and single-use equipment. Over the past…

A Single-Use Process for Production of Recombinant Human Follicle-Stimulating Hormone

by , , , , , and

Follicle-stimulating hormone (FSH) is a heterodimeric glycoprotein consisting of noncovalently linked α and β subunits. It stimulates the growth of immature follicles in ovaries and primary spermatocytes in testes and thus plays an important role in human reproduction (1). Human menopausal gonadotropin for infertility treatment was first introduced into clinical practice in 1950 (2, 3). Subsequently, treatments with urinary FSH have been replaced by recombinant human FSH (rh-FSH), which has been shown to provide several advantages such as absence of…

Pressure Rating for Bioprocess Single-Use Assemblies

by , and

Single-use systems (SUSs) are engineered process equipment solutions for pharmaceutical and biologics production. They offer several key advantages, such as lowering energy costs to reduce utility requirements, minimizing cleaning validation efforts, reducing water and chemical use, and enabling flexibility in manufacturing. Use of SUSs is increasingly popular in almost all fields of bioprocess applications (1, 2). SUSs most commonly comprise components made of polymeric materials, which together create a system or unit operation designed for one-time or campaign use. Single-use…

Monitoring Live Biomass in Disposable Bioreactors

by , , , , , and

Often simply referred to as capacitance, radio-frequency (RF) impedance has been used for over two decades to measure online biomass. It is generally regarded as the most robust and reliable method to monitor live-cell concentrations in mammalian cell culture (1). Many biopharmaceutical companies have now made the transition from conventional glass or stainless steel multiuse (MU) vessels to single-use (SU) bioreactors. Disposables are rapidly becoming the preferred platform for new processes requiring current good manufacturing practice (CGMP) compliance. At the…

Evaluating New Film for Single-Use Bags: Growth Performance Studies with Animal and Human Cells

by , , , , , and

In biopharmaceutical development and manufacturing processes, single-use technology has become widely accepted (1). Storage and cultivation bags are particularly common. They are fabricated from plastics consisting of multilayer films and are typically provided gamma-sterilized by suppliers (2). The bags offer several advantages such as savings in time and cost. Lowered contamination risk results from reduced cleaning and sterilization demands. However, some adverse effects of polymer films on cell growth and metabolism have been reported, both for storage and cultivation bags…

Special Report: Toward Sustainable Engineering Practices in Biologics Manufacturing

by , , , , , , and

Introduction by William P. Flanagan Biopharmaceutical development and manufacturing demand scalable processes that can be quickly developed, easily implemented, and smoothly transferred to production. Disposable, ready-to-use technologies play a crucial role in providing flexibility to support agile biomanufacturing operations. Single-use systems provide process efficiencies by removing steps such as cleaning and cleaning validation, thus allowing for faster change-over between manufacturing runs. The biopharmaceutical industry is increasingly adopting single-use approaches, and the global market for such bioprocessing tools is expected to…
