  • Summary

  • In this podcast, we spoke with Luca Alberici, Senior Vice President and General Manager, Milan Facility, AGC Biologics about the road to their recent EC and FDA approval to commercially manufacture Lenmeldy™ and their future plans in cell and gene therapy. What is Lenmeldy? We began the podcast by talking about AGC Biologics’ Milan site and their FDA approval to commercially manufacture Orchard Therapeutics’ Lenmeldy. Luca explained that Lenmeldy is a gene modified cell therapy product for the treatment of Metachromatic leukodystrophy (MLD), an ultra-rare hereditary disease characterized by accumulation of fats that causes neurodegenerative symptoms. It is a pediatric disease, and patients generally die by the age of five. With this therapy the patient’s stem cells are collected and modified through the use of a lentiviral vector to add a gene called ARSA that encodes for the right form of the enzyme that these patients are encoding wrong. These modified stem cells are then administered back to the patient so they can immune reconstitute not only the immune system, but the cells will also cross correct through secretion of the right form of the enzyme. After just a single shot of the therapy, there is an improvement in their condition and they develop normally, especially if treated in a pre-symptomatic phase. This is the power of gene therapy at its best. The Pathway to FDA Approval for Commercial Manufacture We then discussed the pathway for receiving approval to commercially manufacture this product and how the AGC Biologics Milan team navigated this process. Luca described that it was quite a long journey. AGC Biologics were manufacturing this product at preclinical and clinical phases dating back roughly 15 years. They worked with a series of different sponsors, it was developed by the San Rafaelle Telethon Institute for Gene Therapy in Milan Italy, then GSK continued the clinical development before it was acquired by Orchard Therapeutics. AGC Biologics remained the manufacturer during this time and in 2020 received approval for commercial manufacture of the product in Europe, but FDA requirements are different so over the last two years, they partnered with Orchard Therapeutics and worked to meet the FDA requirements for approval. Luca explained that approval required a great deal of work on the process, the analytics, the quality system, supply chain, and raw materials. One of the most transversal aspects of the validation of a product is getting it ready to be manufactured for the market and it was great to go this last mile with a strong partner like Orchard Therapeutics. He also credits the infrastructure of AGC Biologics, which is a multi-site global organization and provided the Milan site great support in terms of general quality, standards, procedures, and simply by having faced multiple FDA inspections before. The combination of all these factors was what carried them to the finish line, it required extensive teamwork, not only at the Milan site but also the entire organization. The Only Site to Receive EC and FDA Commercial Manufacture Approval I followed up by mentioning how with approval from the European Commission and the FDA, the AGC Biologics Milan facility is the only one in the cell and gene therapy industry to have commercial manufacturing authorization from both the FDA and the EC for LVV and cells. I asked Luca why there are so few CDMO's who have achieved this and what makes the FDA and EMA approval process so challenging? He explained that the Milan site was the first site to receive clinical manufacturing approval for an ex vivo gene therapy in 2003, 21 years ago, when cell and gene therapy was almost nonexistent at the time. They were the first facility to receive approval for commercial manufacturing in Europe for a marketed product in 2015/2016, 10 years ago. Now they are the only site who can do viral vector and cell therapy, both approved from the main authorities,
