INDUSTRY LEADER INSIGHT: Avid Bioservices
Pharma/biotech companies developing therapeutic and vaccine candidates to combat SARS-CoV-2 should partner with a CDMO that has experience in the process development and manufacture of traditional and novel biologics and can support projects from concept to launch. At its single site in California, Avid Bioservices has the expertise and capabilities (development lab, pilot plant, clinical and commercial facilities) needed to accelerate COVID-19 programs from start to finish.
COVID-19 Pandemic Driving Need for Rapid Development
The advent of the COVID-19 pandemic has created an urgent need for new treatments and vaccines to combat infections by the novel SARS-CoV-2 coronavirus. Extensive drug discovery and development efforts are underway to get novel antibodies (and antibody-like treatments) that could lessen the effects of infection by SARS-CoV-2 into clinics as rapidly as possible. Simultaneously, many academic and industry groups are working to advance novel sub-unit and recombinant protein–based vaccines with the potential to illicit strong immune responses against this virus.
These companies need access to small quantities (milligrams to grams) of research-grade protein to investigate their performance in animal models and in vitro tests and are looking for outsourcing partners that can supply material very rapidly, typically from transient expression systems.
Selected pharma and biotech organizations already have encouraging preclinical data, with constructs promising enough to advance into clinical trials. These companies are relying on outsourcing partners with experience working with cell-based expression systems and sufficient bioreactor capacity to quickly develop suitable production processes. Of key importance — especially for a pandemic emergency response — is the ability to rapidly develop compliant production processes and transfer into GMP manufacturing to generate sufficient quantities of clinical trial materials.
Accelerating Timelines while Maintaining Quality and Safety
Timelines for early-phase programs have already shrunk significantly in recent years, owing to the introduction of accelerated approval programs (i.e., Fast Track, Breakthrough Therapy, Priority Review). Biologics CDMOs leverage their process knowledge and have developed platform technologies and new techniques that enable rapid movement from cell line development to upstream and downstream processing. These approaches are highly applicable to COVID-19 projects.
On accelerated timelines, rapid generation of platform cell line systems combined with platform upstream and downstream processes or development paradigms ensure swift IND-enabling process development. With novel cell line expression systems and platform knowledge, process development can finish before clonal cell lines are generated. This saves several months of development work and takes development off the critical path.
However, it is still absolutely essential to follow appropriate quality and safety procedures to ensure that any therapies or vaccines that are developed are well characterized and safe for every clinical trial participant and potential patient. Quality and safety cannot be compromised, even in a scenario like the current COVID-19 pandemic.
Continued Operations Despite Pandemic Restrictions
Since the pharmaceutical industry is an essential business sector, development and manufacturing operations continue at Avid Bioservices. We are actively monitoring COVID-19 developments globally while following the guidelines of our local, state, and federal health authorities.
As a critical supply chain manufacturer for the pharmaceutical industry, we are taking measures to ensure the safety of our employees and to minimize any impact on the continuity of our operations. Hygiene and segregation policies have been revised, and nonessential personnel are working remotely. Personal protective equipment must now be worn by all employees, not just those in the lab and production area. Nonessential onsite visits have been postponed, and shift schedules have been devised to allow for maintenance, repair, and the continuation of research projects that must be conducted in the lab.
We are increasingly leveraging digital technologies for communication, not only among Avid personnel, but also with our suppliers and customers. For example, we used video conferencing to access remote support from an equipment vendor, enabling the successful installation and activation of a new bioreactor system.
For our existing and potential customers that find travel to our site difficult to arrange, Avid previously developed digital programs both for meetings and immersive tours of our site that, according to feedback we have received, make online visitors feel as if they are physically walking through the laboratory and the plant. Access to these technologies has been particularly valuable during the COVID-19 pandemic, and we will continue to build on these capabilities going forward.
From a supply chain perspective, we have not seen any supply challenges beyond what we typically face under normal conditions. Overall, we have not experienced significant impact to our day-to-day operations or our ability to provide process development and drug substance manufacturing services.
Project Management Structure Makes a Difference
For accelerated projects, such as those involving process development and production of antibody and antibody-like constructs to combat SARS-CoV-2, an established and effective project management structure can make the difference between success and failure.
The structure should include a well-defined sequence of project management steps, from an initial kick-off meeting and regulatory strategy meetings to regular project and technical breakout meetings. A project management system should be sufficiently flexible to allow for the development of solutions tailored for each customer and each specific project.
A project timeline — with contracted deliverables and action/decision logs —should be established at the start and made visible to all internal and external team members. A well-defined escalation structure is also essential to ensure that issues that do arise are rapidly brought to the right organizational level — even up to the CEO if needed — and addressed.
Joint steering committee meetings provide the right level of executive oversight to review high-level milestone advancements, discuss updates on the program and potential changes to the scope, and highlight and establish consensuses on opportunities for improvement.
Early Identification of Target Product Profiles Essential
For all projects, but particularly for highly accelerated programs, creating phase-appropriate process development solutions is crucial. That can only be achieved by starting with a thorough client interview that enables the CDMO to fully understand the product and project and determine the target product profile (TPP).
Delving more deeply into the product itself comes next. Knowledge of which product quality attributes are essential will drive the design of the process development program. The right CDMO can help clients fully flesh out the relevant quality attributes to ensure development of the right product for their program. For many antibodies, there is a well-established number of quality attributes, where platform methods are readily available. For more complex antibody-like constructs and recombinant proteins, the level and type of glycosylation and less common posttranslational modifications make each product and process unique. This is where the experience of Avid matters the most — to deliver on programs in the shortest amount of time with the least level of risk.
Investing time up front to develop the TPP can help avoid later problems that can add significant costs or delays. Furthermore, it enables the development of a comprehensive analytical strategy for measuring relevant quality attributes early in the program during development, which accelerates timelines.
CDMOs with extensive experience in biopharmaceutical process development, such as Avid Bioservices, have worked with many different biomolecules and found solutions for a wide range of challenges. Many of the quality attributes are common among biologics, but the importance of each can vary immensely from one product to another, and some are unique. That is where long-term experience helps; it can be applied even to new biomolecules and structures not seen before.
The Value of Tech Transfer Expertise
Technology transfer has a direct impact on the level of success of a cGMP manufacturing campaign, particularly for accelerated projects. A well-established team that supports tech transfer is invaluable. The best approach is to have a cross-functional team — comprising process development, technical operations, MSAT, manufacturing, quality, and supply chain — involved right from the start.
As the project progresses, these team members can keep a close eye on facility fit, supply chain lead times, and other challenges that may require additional attention, such as onboarding of new equipment and qualification of unique raw materials. Experts from technical operations and manufacturing quality also provide feedback to the process development design to help select manufacturing-friendly solutions. Having established technology transfer policies in place that clearly outline individual responsibilities helps to ensure that each individual has the appropriate training on documentation, knows their role in the tech transfer process, and understands the scope of the information required for a successful tech transfer.
Rapid Transition from Early to Late Phase and Commercial Launch
Technology transfer can be even more successful — and efficient — if the transition from early preclinical work to GMP production for early- and late-stage clinical trials and, ultimately, commercial production, is performed seamlessly at one location, as it is at Avid Bioservices. As a result, all phases of development and production proceed within the same quality and project-management systems.
The teams involved are in close proximity and can readily communicate with one another. Process development scientists can interact directly with operators and plant engineers to understand how a process may actually be performed at production scale. This feedback helps process development efforts stay focused on aspects of the process that will have the greatest impact on practical implementation. The result is a lean and cost-effective manufacturing process that is optimally fit for the production facility. Often, one or more key team members follow the project through all of the phases, ensuring continuity of knowledge and operational success.
With this approach, clients can immediately transition to commercial supply with the same company at the same site and avoid the need for technology transfer, either between different outsourcing partners or internally within a CDMO that operates from multiple sites. Any time a process or method is transferred from one site or facility to another, more time and resources must be invested, costs are often greater, and risk is always increased. Taking a project from the beginning to commercial production at the same site is the fastest and most efficient approach.
