"The speed at which the industry has been moving vaccines and treatments for the COVID-19 pandemic into trials and commercial production is unprecedented, and contract development and manufacturing organizations (CDMOs) are playing an important role in quickly adding capacity for clinical trial and commercial manufacturing. Global CDMO Ajinomoto Bio-Pharma Services (Aji Bio-Pharma) is one such CDMO, with US facilities in San Diego, CA, as well as facilities in Japan, Belgium, and India. In May 2020, Aji Bio-Pharma entered a manufacturing agreement with Vancouver, WA-based CytoDyn, a late-stage biotechnology company developing leronlimab, a monoclonal antibody CCR5 antagonist, for multiple therapeutic indications, including severe-to-critical COVID-19 indications, for which the candidate has entered a clinical trial (1).\n\nRon Chantung, associate director of Drug Substance Manufacturing at Aji Bio-Pharma, notes, “While there is always a constant influx of drug products to the market, since the start of the pandemic, the speed and the number of vaccines, therapeutics, and candidates that have entered in clinical development has been extraordinary, making CDMOs and their capacity for manufacturing these products in high demand.”\n\nBioPharm International spoke with Chantung about how CDMOs involved in clinical trial materials’ manufacturing are responding to the current environment and what can be done to speed their clients’ projects.\n\nCurrent trends\n\nBioPharm: How has the COVID-19 pandemic affected clinical trials materials manufacturing and packaging, and what do you see as key challenges?\n\nChantung (Aji Bio-Pharma): In unparalleled ways, COVID-19 has altered the landscape of how CDMOs provide for clinical trials. After months of seeing disruption to clinical trials from travel restrictions and site closures to interrupted supply chains, we are now starting to see that trend slowly reverse.\n\nOne interesting development that we have been keeping an eye on is the supply and demand for cold-chain shipments. With countries imposing travel restrictions due to COVID-19, which may therefore present challenges within shipping lanes, re-assessing validated shipping containers has become a priority to ensure the biologic’s quality attributes maintain stability in transit. CDMOs need to gauge their internal capacity of temperature storage units, form strategic partnerships with logistics companies, and potentially offer validated temperature storage of clinical trial material.\n\nIn response to this ever-changing environment, it is more important than ever for CDMOs to ensure they are proactive with how they plan, resource, and execute programs with their customers, rather than reacting to the larger challenges they are facing with supply chain and general product development.\n\nBeyond monitoring stock and working closely with outside suppliers, we have found that providing customers options to select from in-stock, preferred components and excipients from good manufacturing practice (GMP)-audited and qualified vendors helps reduce variables and speeds up the manufacturing timeline. Additionally, utilizing an existing library of packaging and labeling components and employing existing validated shipping configurations and preferred couriers can help drug sponsors overcome any logistical hurdles to clinical trials.\n\nTechnology developments\n\nBioPharm: Can you comment on any technology developments or best practices that are helping to speed up processes?\n\nChantung (Aji Bio-Pharma): One aspect is the limitations placed on travel and onsite visitors at a CDMO. Organizations are becoming creative in hosting virtual, video audits to maintain the regulatory and quality commitments to agencies and clients, as well as showcase capabilities to prospective business partners. The ability to observe the manufacturing process is something that varies among CDMOs. A virtual and online site visit and audit experience helps ensure customers are meeting their quality obligations for selecting or maintaining a qualified vendor. Through the use of secure document sharing platforms, remote viewing systems, and virtual site tours, clients can be assured they will be able to perform a thorough review of facilities and quality systems and have connections with the subject matter experts and remote access to live action activities to meet their program requirements and quality standards.\n\nFor example, we are offering a personalized, secure remote viewing platform for clients to monitor their filling process through our secure portal. This provides the sponsor with the ability to monitor the operations in real time and to stay connected to their product even when they cannot be physically present. In addition, procedures are in place to host remote audits via technology platforms that support live, interactive conversation and interviews with subject matter experts, guided walk-through of operational areas, and the ability to securely review documents and data.\n\nSpeeding tech transfer\n\nBioPharm: What are some best practices for tech transfer in clinical trial manufacturing?\n\nChantung (Aji Bio-Pharma): Some program details tend to have a bigger impact on the timeline for a client’s tech transfer and clinical program design. We have found that performing compendial methods verifications in parallel with manufacturing activities and working concurrently on batch documentation reviewing supports a quicker release. Performing risk assessments early in clinical development can help fast-track the clinical process and expedite the path to filing.\n\nOther efficient tools for speeding up time to release include working from templated batch documentation to quickly generate a master batch record, utilizing an existing library of packaging and labeling components, and employing existing validated shipping configurations and preferred couriers.\n\nConcurrent and in-parallel reviews and method verifications, minimized analytical transfer scope, and satellite identification samples for bulk drug substance lots sent back to the drug substance manufacturer can decrease the cost and time associated with method transfer. Additionally, early and regular collaboration with an experienced regulatory team can help expedite regulatory submissions, clinical filings, and commercial launches.\n\nTaking all this in to account, Ajinomoto Bio-Pharma Services launched the AJILITY platform. AJILITY is designed for novel therapeutics/vaccines and existing drug products with a new indications that can be used in COVID-19 trials, FDA Emergency Use Authorizations (EUAs), or other programs, providing enhanced flexibility by leveraging our existing, streamlined project configurations. The goal of the AJILITY platform is to minimize variables during tech transfer, manufacturing, and shipping processes and rely on our regulatory expertise to navigate traditional production hurdles to quickly get therapies to clinics.\n\nWhile the pandemic has presented a unique opportunity for our customers to capitalize on Ajinomoto Bio-Pharma Services’ regulatory and manufacturing expertise with our AJILITY integrated drug product manufacturing platform, it will be available beyond the pandemic, for any therapeutic program that needs flexible and responsive support for expediting your lifesaving therapeutic to the clinic.\n\nTech transfer\n\nBioPharm: In tech transfer, what are typically the rate-limiting steps, and how can these be optimized?\n\nChantung (Aji Bio-Pharma): Tech transfer activities for bringing a new product or process into the facility are usually rate limited by analytical method transfers, process transfer, process development, availability of components, and formulation specifics. Especially in early-stage novel therapeutics, there are often gaps between the state of the methods for in-process control and product analysis and what is suitable for current good manufacturing practice (CGMP) operations.\n\nSound technical transfer at a CDMO is founded by aligning equipment, materials, and quality with its clients. Expertise within the technical transfer staff is a key building block. Experienced staff coupled with a sound training program, quality-by-design philosophies, and clear planning (including roles and responsibilities between the client and organization) play an active role in optimizing technical transfer. In addition, harmonizing documentation from technical transfer to GMP production to bridge a seamless transition to the manufacturing team, employing a repertoire of scalable and industry standard equipment, and executing parallel operations all blend to accelerate a client’s timeline to the clinic.\n\nBioPharm: What new technologies in facilities and equipment benefit the tech transfer process for clinical trial material manufacturing? \n\nChantung (Aji Bio-Pharma): The technical transfer piece of clinical trial material manufacturing benefits from high-throughput screening equipment. A CDMO can clearly demonstrate its nimbleness as a business partner via a timeline- and results-driven process development team.\n\nSystems geared toward wide vetting of critical process variables, such as media formulations, cell growth optimization, and resins to capture and polish biologics, are cost effective and time sensitive for the client. For CGMP production of clinical trial materials, a well-known model of single-use equipment returns to the forefront in light of the COVID-19 pandemic. Faster delivery of biologics and reduced validation time through single-use technology plays into a client’s budget, safety, expediency, reproducibility, and quality interests. Flexible, multi-purpose fill lines also provide a benefit by providing various filling options and multiple set ups. Finally, in-house, on-site packaging and labeling systems that are compliant with the Drug Supply Chain Security Act help support clinical success.\n\nReference\n\nAji Bio-Pharma “Ajinomoto Bio-Pharma Services Announces Manufacturing Partnership with CytoDyn for Drug Product Used in COVID-19 Clinical Trials,” Press Release, May 5, 2020."
