Expansion of human allogeneic liver-derived progenitor cells for liver regenerative therapy in serum-free culture conditions.

Human allogeneic liver-derived progenitor cells (HALPCs) display advanced ability to differentiate into hepatocyte-like cells and exhibit potent immunomodulatory, anti-inflammatory, and anti-fibrotic properties. HALPCs have been successfully manufactured under good manufacturing practice (GMP) and are currently in clinical development. A previous phase 2a trial demonstrated the safety of peripheral intravenous infusions of HALPCs and preliminary evidence of the cells' properties to restore liver function in patients with acute-on-chronic liver failure (ACLF), thus potentially improving their survival.

Passive enhanced safety surveillance of GSK's quadrivalent seasonal influenza vaccine in Belgium, Germany and Spain, an observational study: protocol for the 2018/2019 influenza season.

Introduction: The European Medicines Agency requires Marketing Authorisation Holders providing seasonal influenza vaccines in Europe to conduct enhanced safety surveillance accounting for the different age groups based on the vaccine indication, in order to detect any potential increase of local and systemic adverse reactions early in an influenza season. To comply with this requirement, a multicountry European passive enhanced safety surveillance study has been set up to capture and assess adverse events occurring within 7 days following seasonal influenza vaccination. Here we share our surveillance protocol for the 2018/2019 influenza season.
