PEIpro®-GMP is the highest quality grade PEI and the only transfection reagent available on the market supplied in a bag with MPC connectors and weldable tubing, ideal for GMP-compliant closed system manufacturing of clinical grade therapeutic viral vector, such as AAV and lentivirus. Large-scale transfection protocols established with PEIpro® or PEIpro®-HQ are guaranteed to be seamlessly applicable with PEIpro®-GMP for manufacturing of therapeutic viral vectors for late phase clinical trials to commercialization.

PEIpro®-GMP is manufactured in compliance with EU “Guidelines for good manufacturing practices for medicinal products for human and veterinary use” (ICH Q7 and Eudralex Vol 4, Part II, Annex I) and is therefore perfectly suitable as raw material for production of therapeutic viral vectors (eg. AAV, lentivirus) for clinical trials and commercialization.

PEIpro®-GMP manufacturing process

PEIpro®-GMP is manufactured according to a validated manufacturing process in compliance with GMP guidelines to ensure traceability from starting material to the final product. GMP guidelines for manufacturing of ATMP requires that raw materials be of pharmaceutical grade when available (ICH Q7 and Eudralex Vol 4, Part II, Annex I). To address this requirement, both steps of PEIpro®-GMP manufacturing (chemical product and fill & finish) are managed in compliance with GMP guidelines in GMP accredited facilities (Fig. 1). The full list of Quality Controls assessing Identity, Potency, Purity and Safety performed according to European Pharmacopeia is available upon request.

The validated manufacturing process of PEIpro®-GMP allows Polyplus-transfection to obtain an amazing lot-to-lot reproducibility:

Fig. 2. Excellent lot-to-lot reproducibility using PEIpro®-GMP. Suspension HEK293-T cells were seeded at 1 x 106 cells/mL in FreeStyle™F17 medium and transfected with 4 different lots of PEIpro®-GMP with a GFP-expressing plasmid. Transfection efficiency was measured 48h post-transfection by flow cytometry.
Fig. 3. Reproducible high cell viability are achieved with different PEIpro®-GMP lots. Suspension HEK293-F cells were seeded at 1 x 106 cells/mL in FreeStyle™293 medium and transfected with 4 different lots of PEIpro®-GMP reagents following the same protocol. Cell viability was assayed 72h after transfection.

Guaranteed seamless transition from clinical trials to commercialization of viral therapies

PEIpro®-GMP is the highest quality grade PEI transfection reagent for use as raw material in the production of viral vectors (eg. AAV, lentivirus) intended for Human ATMP clinical trials and commercialization. With PEIpro®-GMP to complete the PEIpro® product range, the transition from process development up to commercialization is a straightforward seamless process. To ensure validation process for commercialization, scale-up of therapeutic virus production with PEIpro®-GMP are guaranteed to be comparable to production yields achieved at lower production scale during PD with R&D grade PEIpro® and during preclinical and early clinical trials with PEIpro®-HQ.

PEIpro®-GMP bags with MPC connectors and weldable tubing for ease of use

Closed-systems and single-use technologies are becoming a prerequisite for clinical trials and commercial manufacturing of viral vectors. Consequently, we provide PEIpro®-GMP in bags allowing sterile connection compatible with closed-systems to meet customer demands.

Each PEIpro®-GMP bag is fitted with one tubing made of thermoplastic elastomer (TPE) that can either be welded or used with MPC connectors, which ensures compatibility with all stirred-tank and fixed-bed bioreactors (Fig. 2). With PEIpro®-GMP bags, preparation of large-scale complexes is simplified and guaranteed sterile with a simple “plug and transfect” closed system; thereby considerably reducing contamination risks. Should your closed system require a special configuration, please contact us here.

Ease your risk management process

The introduction of any starting or raw material in the manufacturing process of ATMPs adds potential risk factors. It is therefore essential to evaluate each raw material individually through a risk-based approach. By using PEIpro®-GMP as the transfection reagent to produce viral vectors, you can be confident that quality and safety are ensured:

  • PEIpro®-GMP is manufactured in accredited GMP facilities in compliance with international GMP guidelines ICH Q7 and correspondingly with EU “Guidelines for good manufacturing practices for medicinal products for human and veterinary use” (ICH Q7 and Eudralex Vol 4, Part II, Annex I: Manufacture of Sterile Medicinal Products). The manufacturing process of PEIpro®-GMP is fully documented.
  • PEIpro®-GMP is provided in bags with MPC connectors and weldable tubing suitable for use in closed systems to decrease contamination risks.
  • The aseptic filling process is validated through the performance of media fill tests (MFT).
  • The quality of PEIpro®-GMP is continuously assessed during the manufacturing process in compliance with GMP control testing guideline. Extensive Quality Controls to assess Identity, Potency, Purity and Safety.
  • Identity testing protocols as well as identity satellite sample are available upon request.
  • In order to meet any regulatory requirements and to secure your supply chain, we would be happy to establish Quality Agreements with our customers.
