Market Challenges And Opportunities
Baculovirus Expression System Market Drivers:
- Increasing Demand for Protein Therapeutics and Vaccines: The rising prevalence of chronic diseases such as cancer, autoimmune disorders, and infectious diseases is driving the demand for new therapeutic proteins and vaccines. Pharmaceutical companies are increasingly adopting the baculovirus expression system for the production of complex protein therapeutics as it provides proper post-translational modifications and protein folding critical for functionality. Several blockbuster biologic drugs including monoclonal antibodies and gene therapy vectors utilize baculovirus expression. Moreover, the COVID-19 pandemic has highlighted the need for rapid, scalable manufacturing platforms for vaccines and therapeutics. The baculovirus-insect cell system allows the quick production of vaccine antigens to respond to emerging pandemic threats. For instance, according to Springer Journal of Genetic Engineering & Biotechnology, publication ‘Application of Baculovirus Expression Vector system (BEV) for COVID-19 diagnostics and therapeutics’ in July, 2022, Thousands of proteins have been successfully created using the BEV platform, and it is no longer limited to research purposes; it is now being used on a broad scale to manufacture a variety of biological products, including vaccines. At first, only two Baculovirus Expression Vector (BEV)-derived vaccines were commercialized. Since then, numerous products have been approved for usage including the latest Novavax’s COVID-19 vaccine.
- Technological Advancements in Expression Systems: Key players are investing significantly in R&D to develop improved baculoviral vectors, serum-free media formulations, high-performance cell lines, and automated bioprocessing technologies. For instance, advancements such as flashBACTM and BaculoJuiceTM system enable the rapid generation of high-titer viral stocks leading to increased protein yields. Moreover, innovations in instrumentation such as the introduction of single-use bioreactors provide advanced process controls and scalability. Such technological advancements are making baculovirus expression more efficient, versatile, scalable, and cost-effective for biopharmaceutical production.
- Increasing Strategic Collaborations and Mergers for the Development of Advanced Expression Systems: The increasing investments by rising strategic collaboration and merger activities by key players with emerging players of in life science is increasing research and development activities as well as biopharmaceutical firms to accelerate drug discovery is driving the growth of the baculovirus expression system market. Moreover, government funding and incentives to promote the development of protein therapeutics, vaccines, and biosimilars is expected to present significant growth opportunities. Expanding application areas into emerging fields, such as gene therapy and synthetic biology, will also boost the adoption of Baculovirus expression technologies. For instance, in January 2022, VectorY, a Netherlands-based biotech company dedicated to developing transformative medicines, announced its collaboration with Wageningen University & Research Center to develop novel Baculovirus-based technologies for the production of safe and affordable Adeno-associated viruses (AAV) gene therapies. This partnership will further strengthen VectorY’s proprietary AAV production technologies for the development of next generation gene therapies.
Baculovirus Expression System Market Opportunities:
- Increasing Adoption in Vaccine Development: The COVID-19 pandemic has highlighted the need for agile, scalable vaccine production platforms. The baculovirus-insect cell system allows rapid, economical manufacturing of safe and effective subunit vaccines. With the ability to produce properly folded complex antigens, this system has gained increasing adoption in development of viral vaccines including influenza, hepatitis B, SARS-CoV-2, and others. Moreover, baculovirus is suitable for the production of virus-like particles, which presents target antigens more accurately to the immune system. Therefore, the expanding application for vaccine development presents significant opportunities. For instance, the World Health Organization (WHO) reported in 2021 that over a dozen manufacturers have capabilities to express recombinant proteins using baculovirus for potential COVID-19 vaccines. Overall, increasing investments in vaccine research from public health organizations provide a great opportunity for the baculovirus expression systems to contribute significantly to global immunization efforts in the coming years.
- Growth in Gene Therapy and Viral Vectors: The baculovirus expression system is gaining traction for the manufacturing of gene therapy vectors including adeno-associated viruses (AAV). It allows high-yield, scalable production of rAAV vectors carrying therapeutic genes. With several gene therapy products getting approved and strong clinical pipelines, the rising demand for viral vectors production will drive the adoption of the baculovirus platform. Key players are also making significant investments to leverage baculovirus expression for efficient, economical manufacturing of gene therapies. For instance, the US NIH (National Institute of Health) invested over US$ 644 million in fiscal year 2021 for gene therapy research according to its funding data. The European Commission too allocated US$ 342.2 million toward new gene and cell therapy initiatives indicative growing support and investments into gene therapies by global government bodies will likely fuel greater demand for reliable, scalable and economical viral vector manufacturing using the Baculovirus expression platform. As clinical translation of novel gene therapies ramps up in the coming years to address various genetic disorders, the Baculovirus expression system is anticipated to play a strategic role in supporting their large-scale good manufacturing needs.
Baculovirus Expression System Market Restraints:
- Production Costs: While the baculovirus system provides high expression yields, the overall production costs remains relatively high. Requirement of costly media, proteins, enzymes, and need for maintaining aseptic bioreactor conditions contribute to high costs which may hinder the adoption by small R&D firms and academic institutes. Lack of cost-effective scale-up strategies also restrain the market growth. For instance, according to data published by the United Nations International Labour Organization in 2021, the average wage of skilled biotechnicians and process engineers needed for insect cell culture work is around US$ 35-45 per hour in the U.S. and major European countries. Considering the intensive labor involved, personnel costs are a major contributor to the overall production expenses. This makes baculovirus expression less favorable for research and production of low cost therapies. Unless the production costs are significantly reduced by innovations in culture and downstream processing methods, the technology will see slower commercial uptake.
- Risk of Contamination: The use of live baculoviruses and serum-containing media leads to risks of contamination by adventitious viruses and prions. This raises safety concerns and chances of product rejection, resulting in loss of expensive reagents and bioprocessing materials. Implementing proper biosafety controls and serum-free systems can help mitigate these risks. For instance, according to the publication in Eureka Journal, ‘A New Way of Gauging Baculovirus Residue in Gene Therapy Products’ published in August, 2022, Baculovirus is the high risk of adventitious and endogenous virus contamination. During production, a high level of residual baculovirus from the host cell sometimes remains in the intermediate and final product. Although not fatal to humans, if left undetected the residual baculovirus has the potential to cause inflammation and other immunogenic responses in patients.
