The Cancer Drug Development Forum – CDDF is the platform for all stakeholders involved in the development of cancer drugs.

CDDF Live Webinar Series – May 2021


The Cancer Drug Development Forum held a Live Webinar Series on Lessons learnt from COVID-19 that explored, from different points of view, how the COVID-19 pandemic affected the clinical trial performance and assessment.

The first topic to be discussed as part of this Series is “A Cancer Institute’s experience in the operational cancer clinical trial performance during the COVID-pandemic” and took place on Friday, 07 May 2021 at 18:30-19:30 CEST. This Webinar featured a lecture given by Prof. Jean-Yves Blay (Centre Léon Bérard, France) followed by a discussion session.



The COVID-pandemic has had a major impact on cancer patients, on their treatments but also on the running of cancer clinical trials. How often did appointments have to be cancelled? How did one deal with required care, and have the threats of severe viral pneumonia affected the options for cancer care? How did all of this affect the running of pivotal clinical trials? These are just a few operational questions that Prof. Jean Yves Blay addressed during the discussion.



  • COVID-19 impacted the accrual of newly diagnosed patients in 2020 and  2021, with biases for some specific isotypes
  • Delays in diagnosis  impacted the  clinical presentation of patients and the potential curability in the long term
  • Inclusion in clinical research (academic and pharma driven) program decreased during the first lockdown!
  • The number of  newly activated  trial decreased in 2020, catch up observed in 2021
  • Clinical  research in covid-19 in cancer patients was initiated in record time, but inclusion was impacted by the very variable monthly incidence
