When cancer researchers at the Alliance for Clinical Trials in Oncology designed the Participant Engagement Portal, they started with a simple but radical idea: what if patients in clinical trials felt supported rather than overwhelmed? The result, tested across the United States, reveals that 84% of participants reported positive experiences using PEP, and 93% agreed to be contacted for future research opportunities—a striking testament to what happens when the people running studies actually listen to the people in them.
Clinical trials have long suffered from a fundamental communication problem. Researchers send information one way; patients receive it and comply. But this one-directional flow leaves participants in the dark about study progress, disconnects them from the research mission, and misses crucial opportunities to understand how their daily lives—their housing, food access, financial stability—affect their health outcomes. The Alliance recognized this gap and built PEP as something entirely different: a secure digital space designed not to recruit more bodies into studies, but to treat existing participants as genuine partners.
The proof emerged from a pilot program within the Multi-Cancer Early Detection Biobank Study, a national trial investigating blood tests for early cancer detection. Of 2,221 enrolled participants, 899 opted into PEP—40% take-up for a voluntary tool, an encouraging baseline. What PEP revealed about these participants' willingness to engage was remarkable. Nearly all users, 96%, found the platform easy to access. An equally striking 93% completed surveys without friction. But the deepest insight came from the data itself: participants shared remarkably sensitive information when asked respectfully. Every single respondent provided their ZIP code, and 94% disclosed their ancestry or ethnic origin—information that lets researchers understand how social determinants of health shape cancer trajectories.
The portal's design choices explain this openness. There are no passwords to forget, no username frustrations. Instead, patients receive a unique secure link via text or email, logging in instantly to their personalized space. The interface uses plain language and colorful infographics, steering clear of medical jargon that alienates. Content appears in both English and Spanish, using careful transcreation to honor cultural nuance rather than crude translation. An advisory board of patients, caregivers, advocates, and clinicians shaped every feature—a collaborative approach that showed in the results.
Intriguingly, PEP performed better at local community clinics than at larger academic medical centers, suggesting that smaller, more intimate settings may foster the trust necessary for genuine partnership. The portal also successfully gathered the kinds of patient-centered data that rarely make it into clinical databases: education levels, insurance status, housing stability, food insecurity. This information helps researchers connect the dots between a person's lived reality and their health outcomes—moving oncology beyond the exam room and into the full context of human life.
Norah Crossnohere, the study's lead author and an assistant professor at The Ohio State University, captured the philosophy behind PEP in a single sentence: "By designing PEP directly with patients and advocates, we built a digital space that feels supportive, respectful and incredibly easy to use." That sentence contains the entire revolution. The findings, published in JNCI Cancer Spectrum, suggest that when cancer researchers treat participants as partners and design tools with them rather than for them, engagement soars and the research itself becomes richer, more grounded in the actual lives people live.
