Success in Expressing Certolizumab (Fab) by C1

  • Successful expression of Certolizumab
  • ELISA kit was used to measure and conform Certolizumab expression level (triplicates of samples were

quantified)

  • The calculated expression level was 9.6 g/l, corresponding to 2.0 g/l/day production rate.
  • By using promoter and strain and by further optimized fermentation process we would expect to see similar, if

not higher, expression levels as we see with our best mAb (2.4 g/l/day). Certolizumab production (g/L)

C1 Glycoengineering In Progress

Advantage of C1 over Yeast and CHO

  • Dyadic’s C1’s glycan structure is more mammalian like than typical yeast
  • The native C1 glycan pattern is relatively complex with high mannose type (Man3-Man9)
  • O-glycosylation was not identified in therapeutic proteins expressed in C1
  • Less engineering steps needed for C1
  • Stable genome - defined glycan structure is stable from culture to culture and batch to batch
  • The first steps of Glycoengineering C1 cells has begun and were successful
  • No negative effects on cell viability have been observed with any of the modifications done

DYADIC INFORMATION 32

Glycoengineering in C1

Glycoengineering of C1 strain will provide the formation of various glycan structures to evaluate immunogenicity

C1 typical Glycan structure

  • Unlike most fungi and yeasts, C1 does not have ‘high’ mannose (branched 30-

50 mannose species), but rather has ‘oligo’ mannose and hybrid-type structure.

  • The native C1 glycan pattern is relatively complex with high mannose type

(Man3-Man9) and hybrid type (Man3HexNac-Man8HexNac) glycan forms

  • So far, O-glycosylation was not identified in therapeutic proteins expressed in

C1 but minor level is still possible

C1 future Glycostructures

  • Glycoengineering work is being applied to C1 strain to create a

strain that produces proteins with defined human glycoforms

  • 2

approaches are being applied: i) ’Classical’ mammalian pathway, ii) Alg3 pathway.

  • About 13 steps will be applied for 1.5 – 2 years work
  • The first steps of Glycoengineering C1 cells have been done

successfully.

Glycoengineering C1 Strains

Improving the glycoform structure in C1 Glycoengineered strains:

  • Proteodynamics (France) analyzed glycans from

native protein samples of glycoengineered C1 strains (indicated) by permethylation + MALDI-TOF analysis

  • No fungal high mannose structures present
  • Up to 80% of Man3 structure, the important

precursor for human glycoforms

  • No negative effects on cell viability have been
  • bserved with any of the modifications done
