AGC Biologics Supports Altheia Science’s Gene Therapy Programs

The CDMO’s Milan facility provides lentiviral vector and autologous CD34+ cell-based drug products for clinical testing

SEATTLE, MILAN, July 28, 2022 (GLOBE NEWSWIRE) — AGC Biologics, a leading global Biopharmaceutical Contract Development and Manufacturing Organization (CDMO), today announced a new partnership with Altheia Science, a gene therapy company pioneering cell and gene therapy strategies to treat autoimmune diseases and cancer. Through this partnership, Altheia Science will advance its development of autoimmunity treatments, focused on modulating PD-L1 expression in patients’ hematopoietic stem and progenitor cells, into clinical testing.

AGC Biologics is performing drug product development at its Milan facility using lentiviral vector (LVV) and autologous CD34+ hematopoietic stem and progenitor cell systems. The cells will be transduced using a highly efficient ex vivo lentiviral material to encode the human PD-L1 DNA.

“The AGC Biologics Milan site has a long-standing expertise in successfully developing stem cell-based gene therapies, from clinical testing up to commercialization,” said Paolo Rizzardi, Chief Executive Officer of Altheia Science. “We believe this partnership is key in supporting our gene therapy programs and  making these innovative therapies available to patients.”

The AGC Biologics Milan facility has one of the strongest development and manufacturing track records in the global cell and gene industry, working with virtually any cell type and lentiviral, retroviral and adeno‐associated viral vectors. The site has 25 years of expertise, including manufacturing three commercial products, and teams of scientists with significant development and regulatory experience. The site was the first ex-vivo cell and gene therapy site approved in Europe for GMP manufacturing of clinical and commercial supplies.
