Aseptic Considerations in Formulation, Fill and Finish: Choosing Between Barrier and Isolator Technologies

Biological drug substances are constituent in a wide range of medicinal products with an even broader spectrum of applications. Those include autoimmune-disease treatments (e.g., for arthritis), vaccines, and recombinant therapeutic proteins (e.g., for cancer treatment). What such products all have in common is that they are manufactured using biotechnology and other cutting-edge technologies. Biologics are not as physically robust as their small-molecule counterparts. Hence, during biomanufacturing processes, these complex molecules present a number of challenges. Some of the typical shared…

Creative Formulation: A Useful Approach to Patient-Centered Drug Development

The development of new medicines is a highly regulated process focused on demonstrating efficacy and safety of new products. Although such qualities always will remain the primary focus of drug development, the biopharmaceutical industry gradually has adopted additional design aspects. New approaches can help meet patients’ divergent needs to improve their lives in meaningful ways. Often referred to as “patient-centered” or “patient-focused” drug-product design, such considerations are expected by many experts to become an increasingly dominant part of future drug…

Analysis of Trace-Level, High-Risk HCPs: Proteomics Advances for Preventing Degradation of Polysorbates in Biotherapeutic Formulations

Polysorbate-80 (PS-80) and polysorbate-20 (PS-20) are used widely in formulation of biotherapeutic products for preventing surface adsorption and as stabilizers against protein aggregation (1). Degradation of polysorbates can cause turbidity and potential formation of subvisible particles mainly consisting of poorly soluble hydrophobic free fatty acids (1). Polysorbate degradation is an industry-wide challenge both in biotherapeutics processing and formulation development. The risk of such degradation increases with higher cell densities and greater expression titers in bioprocessing, as well as with higher…

Single-Use Technology for Formulation and Filling: A Case Study from Swissfillon AG and Pall Corporation

Swissfillon AG is a contract manufacturing organization (CMO) based in Switzerland. Fully compliant with current good manufacturing practice (CGMP) regulations, it provides state-of-the-art aseptic filling for pharmaceutical and biotechnology companies, from clinical-phase materials to commercial quantities. This CMO specializes in high-value, difficult-to-fill products. Swissfillon recognized that adoption of single-use systems (SUS) on a commercial scale required major improvements in consistency and reliability compared to manual operations at pilot and clinical-trial scale. The single-use formulation and filling process, which includes an…

Eradicating the Need for Cold-Chain Distribution in the Biopharmaceutical Industry

Cold chain distribution is complicated and critical for formulations that must be kept in very cold temperatures in the pharmaceutical industry, since their stability decreases quickly at room temperatures. The World Health Organization (WHO) has reported over 50% of vaccines are wasted and must be disposed of globally every year due in part to disruption of the cold chain distribution and lack the resources to support the ultracold temperature requirements. A possible solution to the existing problem is Hyalo Technologies’…

Ask the Expert: Formulation Strategies for AAV-Based Gene Therapies

Although formulation and drug-product activities are critical to developing gene therapies, much remains to be learned about their degradation mechanisms, and firm criteria still need to be established for buffer and excipient selection. Sarathi Vijay Boddapati (associate director of formulation and drug development at Catalent Cell and Gene Therapy) joined BPI on 25 March 2021 to present what his company continues to learn about formulating gene therapies by adapting methods used for other biologics. Boddapati’s Presentation Adenoassociated virus (AAV) remains…

Stability Testing: Monitoring Biological Product Quality Over Time

Many physical and chemical factors can affect the quality, safety, and efficacy of biopharmaceutical products, particularly after long-term storage in a container–closure system that can be subject to variations in temperature and light, as well as agitation with shipping and handling. Proteins are inherently complex physiochemically, from their primary amino acid sequences to their higher-order structures, and they require specific conditions to maintain their integrity and functionality. Advanced biological therapies can be even more complicated and particular about their environments.…

eBook: Formulation, Fill–Finish — Biopharmaceutical Drug-Product Trends and Technologies

As with many other aspects of biopharmaceutical development, evolving technologies are transforming drug-product development and manufacturing. In a November 2020 report on the Informa Connect “Drug Delivery Partnerships” meeting, BPI senior technical editor Cheryl Scott reviewed how new delivery-device technologies are bringing together companies with disparate expertise to serve patients with chronic conditions better than ever before. The ever-increasing capabilities of electronics and information technology (IT) not only are enabling development of “smart” delivery devices, but also improving the potential…

Ask the Expert: Translating Inhaled and Nasal Technologies for Biologics Delivery

Gastric delivery is unachievable for most biopharmaceuticals, so drug developers formulate biologics primarily for intravenous infusion or injection. However, inhaled and nasal delivery options are attracting considerable attention because they enable targeted delivery of a wide range of therapeutic proteins. On 23 June 2020, Mark Parry (technical director at Intertek) presented an “Ask the Expert” webinar that described critical considerations for inhaled and nasal delivery for biologics. Parry’s Presentation Because biopharmaceuticals are complex products, developers need compelling reasons to choose…

Ask the Expert: Ultrapure Gelatin Can Optimize Your Excipient Screening for Vaccine Formulation

In his 28 May 2020 “Ask the Expert” presentation, Jeroen Geeraerts (business development manager at Rousselot) highlighted that, as of May 2020, 118 candidate vaccines for the novel coronavirus (SARS-CoV-2) had reached clinical or preclinical evaluation. Of those, 11 use inactivated and live–attenuated approaches, which require strong stabilizing agents to maintain vaccine potency. Geeraerts explained why inactivated and live–attenuated vaccines require stabilizing agents and why vaccine companies prefer pharmaceutical-grade gelatin for such applications. Next, Geeraerts described how his company’s X-Pure…
