Abstract 3427

Background

Extensive research has demonstrated that patients considering early phase oncology trials do not appreciate the design or purpose of these trials and also harbour unrealistic expectations of the personal benefit they can expect from the trial. There have been few interventional studies examining the informed consent process in this setting and they have shown limited effectiveness. We aimed to use a qualitative methodology to understand the perspectives of key stakeholders and identify the areas of need and the potential opportunities for an intervention to improve our informed consent processes.

Methods

We used an experience-based co-design framework which consisted of a semi-structured interview script of ten key questions. Two trained interviewers performed interviews of three consultant medical oncologists, nine clinical fellows, two study managers, two clinical nurse specialists, two focus groups with four patients each and two regulatory officers. We also interviewed four members of our investigator-initiated sponsor team to obtain an understanding of the sponsor perspective. All audio interviews were transcribed, and thematic analysis was performed on the narrative text to extract core themes.

Results

Consistent themes raised by participants included 1. The core elements that participants need to comprehend prior to consenting are that trials are experiments and not treatment, the low prospect of benefit, potential toxicity and the significant time commitment. 2. Participant information sheets (PIS) are too long, too complex and the information is not provided in a patient centred manner. Sponsors were in strong support of shorter and more accessible PIS. 3. Digital media would be acceptable and useful but to be mindful of subgroups of patients who are not as comfortable with digital media.

Conclusions

There is widespread understanding that improvement is required in the length, design and style of participant information sheets for phase 1 oncology trials. Furthermore, digital media would be acceptable to all stakeholders but its development will require ongoing stakeholder engagement to ensure user acceptability.
