Status Recruiting

Clinical Trial Summary

A prospective, open, randomised implementation study in paediatric cancer patients. The study aims to determine whether a personalised approach will result in an overall reduction in clinically relevant adverse drug reactions (ADRs) and to evaluate the economic and quality of life impacts. Participants will be randomised to receive personalised guided prescribing of supportive care therapy (study arm) or standard of care (control arm) for a period of 12 weeks. The follow up period includes prospective patient reporting of symptoms and quality of life through electronically delivered surveys, for a maximum of 12 months.

Clinical Trial Description

One of the main areas of precision medicine that is easily implementable is pharmacogenomic testing. Germline testing of genes predisposing to drug toxicity or inefficacy can inform drug selection and dosing. This steers away from the historical 'trial and error' approach, avoids unnecessary adverse drug reactions (ADRs) and can potentially impact on health economic savings, through reduction in readmissions and admissions with ADRs. This study will be a prospective, open, randomised implementation study in paediatric and adolescent patients with a new diagnosis of cancer or who are proceeding to first haematopoietic stem cell transplantation (HSCT). The current standard of care for paediatrics in Australia involves pharmacogenomic testing for TPMT and NUD15, for patients with acute lymphoblastic leukaemia. Participants of the study will receive pharmacogenomic testing across a range of clinically relevant variants. Participants will be randomised to either the control arm or the study arm. Test results for participants in the study arm will be used to guide the dose and drug selection of 27 drugs commonly used in supportive care. The pharmacogenomic test results will be released to the study arm at week 4 and to the control arm at week 13, after the 12 week intervention period. To determine whether pre-emptive pharmacogenomic testing does reduce clinically relevant adverse drug reactions, the Paediatric Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (Ped-PRO-CTCAE) survey will be delivered at 3 time points within a 12 week period. This survey is a patient reported outcome measurement tool developed to evaluate symptomatic toxicity in participants receiving cancer therapy. After survey completion, semi-structured interviews will be conducted by an academic pharmacist with the aim of generating a CTCAE grade of severity for each of the symptoms defined in the Ped-PRO-CTCAE and assessing the causality of an adverse drug reaction using the Liverpool Adverse Drug Reaction Causality Assessment Tool (Liverpool ADR-CAT). These mechanisms will support the assessment of both severity and causality of any adverse drug reactions. To evaluate the economic and Quality of Life impacts (QoL), participants will also complete The Child Health Utility 9D (CHU9D) QoL surveys specific to children and young adults at 3 timepoints over the 12-month period and consent to a Health Economics Analysis. This includes collection of Medicare Benefits Schedule (MBS)/ Pharmaceutical Benefits Scheme (PBS) data from Services Australia and Victorian Data Linkage Group to compare the costs of management of both the control and study arm. Data from the study will be securely stored on the REDCap database. Patients will be allocated a unique patient identifier prior to their de-identified data being added to the database. ;
