We were looking forward to seeing everyone at the CDDF Workshop in Amsterdam. However, due to the continuing threat of the COVID-19 pandemic and its impact on our ability to travel, after thoughtful discussions, the Cancer Drug Development Forum has decided to move the conference into a fully virtual meeting. The safety and well-being of our speakers and attendees is our priority. The virtual meeting will allow us to safely serve our participants and provide new opportunities for knowledge exchange, engagement and interaction.
