Clinical Production
GMP Plasmid DNA
Waisman's platform plasmid manufacturing process yields up to multi-gram quantities of clinical, CGMP grade plasmid DNA that can be used for direct injection or ex-vivo/further manufacturing applications. Waisman has delivered plasmid DNA vaccines up to Phase 2 clinical trials and can support Phase 3/commercial for plasmid DNA used as an ancillary material.
Plasmid Production Specifics
- Clone optimization and Master/Working Cell bank production and testing
- CGMP production of multi-gram batches for direct injection and ancillary use
- 30-120L steam-in-place fermentor capacity
- Scalable manufacturing process free of organic solvents and animal derived products
- Quality Control testing including HPLC and qPCR
- In-house development of custom potency assays
