Abstract

Background

The Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) complements standard adverse event (AE) reporting in oncology trials. We assessed patient-reported symptomatic AEs in individuals receiving osimertinib 80mg once daily or chemotherapy for advanced non-small cell lung cancer (NSCLC) in the AURA3 trial, using the PRO-CTCAE.

Methods

AURA3 (NCT02151981) was a multinational, open-label, randomized phase III trial involving 419 patients.1 As part of exploratory analyses, individuals for whom validated local language versions were available (in English, German, Japanese or Spanish) were asked to complete the PRO-CTCAE by e-device, weekly for 18 weeks and then every 3 weeks.

Results

In total, 161 patients (38%; 102 osimertinib, 59 chemotherapy) provided data for PRO-CTCAE analysis (mean age: 64 years; 63% women). The number of patients providing PRO-CTCAE data fluctuated between different items and time points, and decreased over the study period. Of patients on osimertinib providing information on acne/pimples, 37%, 38%, 32% and 29% reported having acne/pimples at baseline, 4 weeks, 12 weeks and 24 weeks, respectively, compared with 30%, 19%, 14% and 12% on chemotherapy. Most cases (>90%) were mild. Reported rates of diarrhoea changed little over time post-baseline and were higher with osimertinib than with chemotherapy (32% vs 36% at baseline, 47% vs 28% at 4 weeks, 53% vs 33% at 12 weeks, 45% vs 21% at 24 weeks). Most cases were mild or moderate. Fatigue (64% vs 72% at baseline, 72% vs 89% at 4 weeks, 55% vs 89% at 12 weeks, 60% vs 79% at 24 weeks) and decrease in appetite (54% vs 53% at baseline, 42% vs 75% at 4 weeks, 35% vs 69% at 12 weeks, 33% vs 46% at 24 weeks) were reported less commonly with osimertinib than with chemotherapy. Most cases were mild.

Conclusions

Self-reported data from patients with NSCLC treated with osimertinib or chemotherapy showed changes over time in AE rates from start of treatment and differences in prevalence of patient-reported AEs (PRO-CTCAEs) with osimertinib versus chemotherapy.
