ABSTRACT
INTRODUCTION: The assessment of quality of life (QoL) should be one of the main objectives in paediatric clinical trials. Even though researchers, regulators and advocates support the use of patient-reported outcomes (PROs), this has not been fully implemented. The aim of this study is to assess the measurement of QoL and the usage of PROs, palatability assessments and medication diaries in early-phase clinical trials for childhood and adolescent cancer. METHODS: Early-phase clinical trials for children and adolescents with cancer opened between 2005 and 2022 at the Royal Marsden Hospital (London, UK) and Vall d'Hebron University Hospital (Barcelona, Spain) were interrogated for trial characteristics and the use of QoL questionnaires, PROs, palatability assessments and medication diaries. RESULTS: Overall, 72 clinical trials were analysed: 12 (16.7%) evaluated QoL and eight (11.1%) evaluated PROs. Palatability was tested in 21/40 (52.5%) trials of oral drugs and 23/72 (31.9%) incorporated medication diaries. No studies mentioned patient involvement in the trial protocol. Use of PROs increased from one of 36 (2.8%) to seven of 36 (19.4%) between the first period (2005-2016) and the second period (2017-2022) (p = .02). Implementation of medication diaries increased from seven of 36 (19.4%) to 16/36 (44.4%) in each period, respectively (p = .02). CONCLUSION: Only a minor proportion of the international/multicentric early-phase trials evaluated included QoL/PROs and medication diaries or palatability questionnaires to help assess these, although this trend seems to be increasing over recent years. Greater implementation of QoL/PROs has the potential to improve the patient's wellbeing and facilitate symptom control, to enhance patient/parent involvement in future trial designs and to provide information for drug prioritisation.

Early phase trials are crucial in developing new therapies for poor prognosis childhood malignancies. Outcomes and toxicities of children treated on phase I/II trials at the Royal Marsden, one of the largest pediatric oncology early phase trial units in Europe, were examined to provide a baseline dataset and generate hypotheses. All patients recruited over a 10-year period to December 2011 were included. Variables including baseline characteristics, time on study, survival, toxicities, and admissions were collected. Seventy-two patients were recruited to 21 trials (5 phase I, 16 phase II; overall 12 involved molecularly targeted agents). Median age at consent was 12.4 years. Dose-limiting toxicities were rare in phase I trial participants (2 of 15 evaluable patients, 13%); the most common reason for leaving trials was disease progression (76%), rather than drug toxicity (1.7%). Median time on trial was 1.3 months (phase I patients) and 3.3 months (phase II). Early phase trials in children are safe and unexpected toxic side effects are infrequent. Patients and their families are willing to travel to access novel therapies, although the overall prognosis for these individuals is poor. Continued expansion of the portfolio is needed ultimately to improve the outcomes for those with resistant disease.
