Evolutionary analyses suggested that EqHBV originated in Africa several thousand years ago, commensurate with the domestication of donkeys. In sum, EqHBV naturally infects diverse equids and mimics HBV infection patterns. Equids provide a unique opportunity for preclinical testing of novel therapeutics for CHB and to investigate HBV/HCV interplay upon coinfection.Post-approval changes (PACs) are inevitable and necessary throughout the life of a drug product. Because many PACs require prior approval by individual regulatory agencies each having their own reporting requirements and approval timelines this results in companies having to manage several versions of a manufacturing process at the same time. The global regulatory complexity increases risk of drug shortages. Chief Quality Officers and Heads of Quality from more than 20 global pharmaceutical companies have come together to speak with One-Voice-Of-Quality (1VQ) and develop solutions to this problem by developing a science and risk-based approach to manage more PACs in the PQS rather than submitting these as prior approval supplements. The paper ″Industry One-Voice-of-Quality (1VQ) Solutions. Effective Management of Post-Approval Changes in the Pharmaceutical Quality System (PQS) - Through Enhanced Science and Risk-Based Approaches″ (PDA Journal of Pharmaceutical Science and Technology July 2020, 74 (4) 456-467; DOI https//doi.org/10.5731/pdajpst.2020.011734) outlines such solutions. Pharmaceutical companies already conduct Management Review (MR) according to ICH Q10. This One-Voice-Of-Quality (1VQ) paper is a practical guide on how companies can expand the MR to also evaluate and demonstrate the effectiveness of their Pharmaceutical Qualit
