PURPOSE: The aim of this study was to investigate the efficacy and safety of prophylactic administration of 5 mg olanzapine (OLZ) combined with neurokinin 1 receptor antagonist (NK1RA), 5-hydroxytryptamine type-3 receptor antagonist (5-HT3RA), and dexamethasone (DEX) to prevent nausea and vomiting in carboplatin (CBDCA) combination therapy for patients with gynecological cancer.
METHODS: We conducted a single-arm, multi-institution, phase II study. Gynecological cancer patients scheduled to receive AUC ≥4 mg/mL/min CBDCA were enrolled. All patients received 5 mg OLZ (once daily after supper on days 1-4) combined with NK1RA, 5-HT3RA, and DEX. The primary end point was complete response (CR; no emesis and rescue therapy) during overall phase (120 h after the start of carboplatin administration).
RESULTS: Between May 2018 and June 2019, 60 patients were enrolled from 3 institutions in Japan. A total of 57 patients who met the criteria were included in the efficacy and safety analysis. The CR rate for the overall phase was 78.9%. Acute (0-24 h) and delayed phases (24-120 h) were 96.5% and 80.7%, respectively. Somnolence was observed in 73.7% patients. However, somnolence of grade 2 or higher was observed in only 3.5% of cases. There were no grade 3 or 4 toxicities associated with OLZ.
CONCLUSIONS: Preventive use of OLZ combined with standard triplet therapy had promising activity with manageable safety, suggesting that this combination could be an effective standard treatment option for patients with AUC ≥4 mg/mL/min CBDCA combination therapy.
