A five-year community outreach and engagement effort by the Abramson Cancer Center at the University of Pennsylvania to increase enrollment of Black patients into cancer clinical trials more than doubled the percentage of participants, improving access and treatment for a group with historically low representation in cancer research. The percentage of patients enrolled into a treatment clinical trial, for example, increased from 12 to 24 percent. A significant increase was also observed in non-therapeutic interventional and non-interventional trials. The findings will be presented at the American Society of Clinical Oncology annual meeting on June 5.
