Hoskins5 and Ryan Nguyen5  \nAbstract  \nBackground Ineffective dissemination of cancer research and information among the public contributes to cancer inequities. Dissemination rarely involves efforts to engage non-research audiences and end-users in developing effective messaging. Efforts to promote equity in clinical trial participation may benefit from marketing strategies traditionally applied in the business sector. Black Americans suffer the highest death rates from most cancers than any other race/ethnicity, yet only 5% of patients enrolled in cancer clinical trials are Black. Our team used a marketing strategy framework to create a culturally responsive public service announcement (PSA) video to increase awareness of clinical trials among Black audiences.  \nMethods We partnered with a marketing recruitment firm and a marketing agency to conduct six focus groups (n = 54) with social support networks of Black cancer survivors and Black community members. Maximum variation sampling was used to recruit a national sample of eligible participants that varied in age, education, geographic region, and gender. Focus groups were conducted over three phases that informed script development, script and storyline testing, and sought feedback on the PSA video post-production. We used the Marketing and Clinical Trials Reference Model to guide marketing strategies, data collection, video content development and production. We used rapid qualitative data analysis techniques to identify themes for each phase to guide PSA development.  \nResults Partnered with a film production company, we produced a 2-min PSA video that uses professional actors and storytelling and marketing techniques to describe clinical trials, provide relevant statistics, address barriers to participation expressed by participants, and provide credible resources to seek further information. We also produced 30 s and 60 s versions of the PSA to accommodate different marketing media outlets. Participants felt the videos were engaging and relatable and that the messaging was clear. The videos ignited meaningful discussions about clinical trial participation and motivated participants to share the information learned.  \n*Correspondence:  \nVida Henderson [vahender@fredhutch.org](vahender@fredhutch.org)  \nFull list of author information is available at the end of the article  \n© The Author(s) 2025.
