The transition from rare disease indications to wider patient populations in hemophilia and potentially more common conditions is a major opportunity for manufacturing scale-up.

Viral Vector Development Market Drivers, Restraints, and Opportunities

• The main demand driver is the growth of the gene therapy pipeline, as each clinical program progressing from preclinical to commercial production requires increasing amounts of vector manufacturing capacity.
• The supply bottlenecks are coming from manufacturing capacity constraints, where the demand from gene therapy developers is outstripping the available GMP production capacity at qualified CDMOs.
• Platform standardization and process intensification are driving down the vector cost per dose, improving the commercial feasibility of gene therapies for larger patient populations.

Dynamics of gene therapy pipeline, manufacturing capacity constraints, and evolution of process technology drive the viral vector development market. Growth drivers include: clinical pipeline expansion, therapy commercialization and CDMO capacity investment.

Gene Therapy Pipeline as Demand Driver

There are more than 3,000 gene therapy programs globally and each of them will require viral vector manufacturing at increasing scale as programs progress through clinical development. Each step from preclinical to Phase I to Phase III to commercial is an order of magnitude increase in the volume of vector produced.

Manufacturing Capacity Constraints

Demand for GMP viral vector manufacturing outstrips available capacity at qualified CDMOs. “To increase capacity, it takes 2 to 4 years of facility construction, equipment qualification and regulatory approval before production can begin. This supply constraint gives established CDMOs pricing power and spurs investment in new manufacturing facilities.

Process Intensification and Cost Reduction

Recent advances in suspension cell culture, perfusion bioreactors and downstream purification are leading to higher vector yields per batch and lower cost of manufacturing per dose. Process intensification provides the commercial scale production economics to justify gene therapy pricing for larger patient populations than ultra-rare diseases.
