International (non-US) Grants Portal

GW is passionate about supporting communities which are affected by the therapy areas in which we work. We are open to applications for therapy areas in which GW are actively involved in. GW has an international grants committee which considers each application on its own merits. This committee comprises of members of our Ethics and compliance team, our Medical team and our Finance team. An application for funding does not guarantee that a grant will be made.

Please ensure that you provide all information asked for in the grants application. Any missing information may delay or affect the outcome of your application.
