Companies Struggle to Accelerate Production of Bespoke mRNA Therapies

Leading companies like Moderna and BioNTech are actively transforming their manufacturing processes to create personalized mRNA therapies, particularly for individualized cancer vaccines, which present far more complex production demands than mass-market vaccines like those for COVID-191 4.

The biggest challenges with bespoke mRNA therapies include collecting and sequencing patient samples rapidly, coordinating workflow for individualized batches, and scaling production processes that traditionally favored large, uniform lots1 3.

Technical hurdles include the efficiency of in vitro transcription (IVT), purification steps required for high purity and quality, achieving sterility, and maintaining consistent lipid nanoparticle (LNP) formulation; these issues increase costs and slow production3 5.

Distribution and logistics remain complicated by LNP-mRNA therapies’ need for ultra-low temperature storage (commonly -20°C to -80°C), creating cost and infrastructure barriers, especially for global or remote delivery5.

Regulatory pathways for personalized mRNA therapies are far more complex than for mass-produced drugs, since each therapy batch may require specific documentation and quality assurance for individual patients’ sequences and formulations7.

Advances in AI-driven process optimization, real-time production monitoring, and single-use manufacturing hardware have improved speed and flexibility, but challenges persist in cost control, supply chain resilience, and rapid regulatory approval7 17.

Recent market innovations include digital manufacturing platforms and blockchain-based tracking, which help manage complicated supply chains and support regulatory compliance for individualized therapies7.

Despite these hurdles, the mRNA therapeutics market is rapidly expanding into oncology and rare diseases, with leading companies increasing investment in next-generation manufacturing solutions and strategic collaborations between CDMOs (contract development and manufacturing organizations) and biotech firms2 7 8.
