Abstract
Abstract
AIMS
Early phase cancer clinical trials have become more complicated and patients often misunderstand their nature and purpose. CONSENT (NCT04407676) is a randomised controlled trial testing whether enhanced informed consent for patient education can improve comprehension – since patients with glioblastoma multiforme (GBM) have a higher rate of baseline cognitive impairment, we studied this group separately.
METHOD
GBM patients (from the ICE-CAP Phase 1 study - NCT03673787), underwent the schedule for the standard CONSENT arm - full length trial PIS, Quality of Informed Consent Questionnaire Parts A and B (QuIC-A and QuIC-B), experimental intervention (2 page study aid and 10 educational videos), and a repeat QuIC-A and QuIC-B. The primary endpoint for this subgroup was the difference in QuIC-A scores before and after the intervention using a paired t-test.
RESULTS
6 patients with GBM were recruited - 3 did not complete any study questionnaires. The three pre intervention QuIC-A scores were 70, 81, 88, with a mean of 75 (unit reference 76). The three pre intervention QuIC-B scores were 69, 62, 75 with a mean of 69 (unit reference is 91). Only one patient completed the post intervention questionnaire - their QuIC-A score moved from 88 to 100.
CONCLUSION
This study demonstrates the significant difficulties in studying comprehension in patients with GBM considering early phase trials. There is a need for creative multi-modality solutions to provide information to GBM patients considering clinical trials, and novel tools to assess the effectiveness of these solutions.

Abstract
INTRODUCTION Early phase cancer clinical trials have become increasingly complicated in terms of patient selection and trial procedures-this is reflected in the increasing length of participant information sheets (PIS). Informed consent for early phase clinical trials has been contentious due to the potential ethical issues associated with performing experimental research on a terminally ill population which has exhausted standard treatment options. Empirical studies have demonstrated significant gaps in patient understanding regarding the nature and intent of these trials. This study aims to test whether enhanced informed consent for patient education can improve patient scores on a validated questionnaire testing clinical trial comprehension. METHODS AND ANALYSIS This is a randomised controlled trial that will allocate patients who are eligible to participate in one of four investigator-initiated clinical trials at the Royal Marsden Drug Development Unit to either a standard arm or an experimental arm, stratified by age and educational level. The standard arm will involve the full length trial PIS, followed by electronic or paper administration of the Quality of Informed Consent Questionnaire Parts A and B (QuIC-A and QuIC-B). The experimental arm will involve the full length trial PIS, exposure to a two-page study aid and 10 online educational videos, followed by administration of the QuIC-A and QuIC-B. The primary endpoint will be the difference (using a one-sided two-sample t-test) in the QuIC-A score, which measures objective understanding, between the standard and experimental arm. Accrual target is at least 17 patients per arm to detect an 8 point difference (80% power, alpha 0.05). ETHICS AND DISSEMINATION Ethics approval was granted by the National Health Service Health Research Authority on 15 June 2020-IRAS Project ID 277065, Protocol Number CCR5165, REC Reference 20/EE/0155. Results will be disseminated via publication in a relevant journal. TRIAL REGISTRATION NUMBER NCT04407676; Pre-results.
