Background
Ovarian cancer (OC) is a highly lethal gynecological cancer. Olaparib maintenance therapy was effective and well-tolerated in pivotal RCTs. However, nationwide real-world safety information is limited in China. This multicenter, prospective, observational drug intensive monitoring study monitored the safety of olaparib in a largest-to-date, real-world Chinese OC cohort.Methods
Eligible OC patients had received ≥ 1 dose of olaparib. Follow-up extended up to 30 days post-olaparib discontinuation or maximally for six months post-enrolment. Primary and secondary endpoints were adverse events (AEs) in all OC patients and in special populations (hepatically/renally impaired before olaparib treatment; aged > 65 years), respectively.Results
By Jun 30, 2023, 799 patients from 33 sites were enrolled. By data cut-off (Dec 29, 2023), 796 patients treated with olaparib were analyzed. The median age was 55 years (range, 25-85). Of 796 patients, 490 (61.6%) were newly diagnosed and 306 (38.4%) had platinum-sensitive relapsed OC. AEs occurred in 343 (43.1%) patients, and 257 (32.3%) had treatment-related AEs. Anemia (19.2%) was the most common AE. Sixty-eight (8.5%) patients experienced grade ≥ 3 AEs, and 3 had AEs of special interest (AESIs; 0.4%; 1 myelodysplastic syndrome, 1 breast cancer, 1 pneumonitis). 45.2% (19/42) patients with hepatic impairment at baseline, 38.5% (5/13) with renal impairment at baseline and 38.6% (49/127) aged > 65 years experienced any AEs, respectively. No AESIs were reported in these subgroups.Conclusions
In this largest-to-date, first prospectively enrolled, real-world Chinese OC cohort, olaparib demonstrated a well-tolerated and manageable safety profile (including in special populations) with appropriate management, regardless of treatment lines. No new safety signals were identified.
