ABSTRACT
BACKGROUND:
The phase III FLAURA2 (NCT04035486) study will evaluate efficacy and safety of first-line osimertinib with platinum-pemetrexed chemotherapy versus osimertinib monotherapy in epidermal growth factor receptor mutation-positive (EGFRm) advanced/metastatic non-small-cell lung cancer (NSCLC). The safety run-in, reported here, assessed the safety and tolerability of osimertinib with chemotherapy prior to the randomized phase III evaluation. PATIENTS ANDMETHODS:
Patients (≥18 years; Japan ≥20 years) with EGFRm locally advanced/metastatic NSCLC received oral osimertinib 80 mg once daily (QD), with either intravenous (IV) cisplatin 75 mg/m2 or IV carboplatin target area under the curve 5, plus pemetrexed 500 mg/m2 every 3 weeks (Q3W) for four cycles. Maintenance was osimertinib 80 mg QD with pemetrexed 500 mg/m2 Q3W until progression/discontinuation. The primary objective was to evaluate safety and tolerability of the osimertinib-chemotherapy combination.RESULTS:
Thirty patients (15 per group) received treatment [Asian, 73%; female, 63%; median age (range) 61 (45-84) years]. Adverse events (AEs) were reported by 27 patients (90%) osimertinib-carboplatin-pemetrexed, 100%; osimertinib-cisplatin-pemetrexed, 80%. Most common AEs were constipation (60%) with osimertinib-carboplatin-pemetrexed and nausea (60%) with osimertinib-cisplatin-pemetrexed. In both groups, 20% of patients reported serious AEs. No specific pattern of AEs leading to dose modifications/discontinuations was observed; one patient discontinued all study treatments including osimertinib due to pneumonitis (study-specific discontinuation criterion). Hematologic toxicities were as expected and manageable.CONCLUSIONS:
Osimertinib-chemotherapy combination had a manageable safety and tolerability profile in EGFRm advanced/metastatic NSCLC, supporting further assessment in the FLAURA2 randomized phase.Palavras-chave
