OVERVIEW OF mRNA MANUFACTURING FOR THERAPEUTIC DEVELOPMENT

Manufacturing mRNA requires significant expertise, equipment, and enterprise. Many steps are performed at the technical level to assemble a product that is more stable, less immunogenic, and better expressed in whatever cellular context it is used. The challenge of mRNA manufacturing means that a final product is sometimes produced by one company, two partnering companies, or multiple partners each with its own capabilities.

mRNA Manufacturing Process

STEP 1

Project design and process
development

•  Sequence design

•  Chemical modifications

•  Purity and quality specs

•  Quantity (scale-up) needs

STEP 2

Plasmid preparation

•  Bioreactor fermentation

•  Harvest, lysis

•  Linearization

•  Ultrafiltration/diafiltration

•  Chromatographic purification

STEP 3

IN VITRO (IVT) SYNTHESIS OF mRNA​

Post-transcriptional Capping

CO-TRANSCRIPTIONAL CAPPING

Added manual steps, hands-on time, and 

manufacturing costs

Simplified workflow, reduced time, and

manufacturing costs

ivt synthesis reaction

PURIFICATION

  • DNA, enzyme, NTP removal
  • Chromatographic purification
  • Flow filtration

IVT Synthesis Reaction +
Capping

  • Methods: ARCA, CleanCap® reagent
  • Only enzyme required is RNA
    polymerase
  • Post IVT reaction modifications
    possible

capping

  • Method: Enzymatic
  • Capping enzyme necessary

CleanCap technology gets you higher yield, lower immunogenicity, reduced timelines, and improved manufacturing process flow

STEP 4

PURIFICATION

•  DNA, enzyme, NTP removal

•  Chromatographic purification

•  Flow filtration

STEP 5

QA and QC Testing

•  Mass spectrometry analytics

•  NTP impurities

•  Salt content

•  Often custom, as needed

(OPTIONAL)

lnp encapsulation

purification

qc and testing

STEP 6

FILL AND FINISH

•  Sterile filtration

•  Aseptic filling

•  Final quality check

STEP 7

SHIP

•  Temperatures critical for stability
maintained throughout shipment

STEP 8

mRNA Manufacturing Permits
Therapeutic Innovation

Innovative mRNA products drive new
therapeutic development opportunities

mRNA products available as substances
or drugs:

  • mRNA substance: pure (only) active
    pharmaceutical product
  • mRNA drug: mRNA therapeutics
    supplied in their final formulation (e.g.,
    LNP encapsulated)
