In Germany, manufacturers can seek scientific advice separately from the Federal Institute for Drugs and Medical Devices (Bundesinstitut für Arzneimittel und Medizinprodukte, BfArM), the Federal Institute for Vaccines and Biomedicines (Paul-Ehrlich-Institut, PEI), and the Federal Joint Committee (Gemeinsamer Bundesausschuss, G-BA). Alternatively they may opt for joint scientific advice to integrate regulatory and HTA perspectives. Choosing the right approach can streamline development, reduce risks, and optimise resource allocation.
