PURPOSE In the ENGOT-OV16/NOVA trial (ClinicalTrials.gov identifier: NCT01847274 ), maintenance therapy with niraparib, a poly(ADP-ribose) polymerase inhibitor, prolonged progression-free survival in patients with platinum-sensitive, recurrent ovarian cancer who had a response to their last platinum-based chemotherapy. The objective of the study was to assess the clinical benefit and patient-reported outcomes in patients who had a partial response (PR) and complete response (CR) to their last platinum-based therapy. PATIENTS AND METHODS A total of 553 patients were enrolled in the trial. Of 203 patients with a germline BRCA mutation (g BRCAmut), 99 had a PR and 104 had a CR to their last platinum-based therapy; of 350 patients without a confirmed g BRCAmut (non–g BRCAmut), 173 had a PR and 177 had a CR. Post hoc analyses were carried out to evaluate safety and the risk of progression in these patients according to g BRCAmut status and response to their last platinum-based therapy. Ovarian cancer–specific symptoms and quality of life were assessed using the Functional Assessment of Cancer Therapy–Ovarian Symptom Index. RESULTS Progression-free survival was improved in patients treated with niraparib compared with placebo in both the g BRCAmut cohort (PR: hazard ratio [HR], 0.24; 95% CI, 0.131 to 0.441; P < .0001; CR: HR, 0.30; 95% CI, 0.160 to 0.546; P < .0001) and the non–g BRCAmut cohort (PR: HR, 0.35; 95% CI, 0.230 to 0.532; P < .0001; CR: HR, 0.58; 95% CI, 0.383 to 0.868; P = .0082). The incidence of any-grade and grade 3 or greater adverse events was manageable. No meaningful differences were observed between niraparib and placebo in PR and CR subgroups with respect to patient-reported outcomes. CONCLUSION Patients achieved clinical benefit from maintenance treatment with niraparib regardless of response to the last platinum-based therapy.

5534 Background: NORA is the first, phase III, randomized controlled trial (RCT) that demonstrated individualized starting dose regimen of niraparib, which significantly improved PFS in Chinese patients with platinum-sensitive recurrent ovarian cancer (PSROC). This sub-group analysis evaluated the efficacy of niraparib maintenance therapy with and without secondary cytoreductive surgery (SCS) in PSROC. Methods: The NORA phase III RCT included adult (≥18 years) Chinese women with PSROC who were randomized in a 2:1 ratio to receive oral niraparib (n = 177) or matched placebo (n = 88). This retrospective subgroup analysis was based on the progression-free survival (PFS) of niraparib maintenance therapy in these two groups of patients with PSROC, patients with SCS, and patients without SCS. The PFS was assessed by blinded independent central review. The Kaplan-Meier (KM) estimator and log-rank test were performed to calculate the median PFS time. Results: Of the 265 evaluable patients, 69 (26.0%) patients received the SCS (niraparib, n = 48; placebo, n = 21), and 196 (74.0%) patients were without SCS (niraparib, n = 129; placebo, n = 67). Among patients with and without SCS, baseline characteristics for BRCA mutation were 26.1% vs 41.8%, complete response to last platinum-based chemotherapy were 68.1% vs 43.9%, time (6-12 months) to progression after penultimate therapy were 23.2% vs 34.7%, respectively. Treatment with niraparib led to a significant reduction of risk to disease progression compared with placebo in patients with SCS (Hazard ratio [95% CI]: 0.32 [0.13–0.78]; P = 0.0102) and without SCS (0.34 [0.23–0.50]; P< 0.001). Moreover, in the subgroups of patients who received SCS, niraparib maintenance therapy had a significantly longer PFS compared with placebo (Median [95% CI]: not reached [18.33 – not estimable] vs 5.75 months [3.68 – not estimable]; P = 0.0102). This trend was also similar in the subgroup of patients who did not receive SCS (Median [95% CI]: 10.28 months [7.49 – 18.37] vs 4.90 months [3.71 – 5.52]; P < 0.0001). Conclusions: The results from this retrospective sub-group analysis revealed that niraparib maintenance therapy provided significant clinical efficacy in patients with PSROC, irrespective of SCS. Clinical trial information: NCT03705156.

e18710 Background: With the advent of poly(ADP-ribose) polymerase inhibitors (PARPi), options for first-line (1L) maintenance therapy in ovarian cancer (OC) have evolved in the US. This study described the use of 1L maintenance and assessed predictors of 1L maintenance use among PARPi-eligible patients (pts) with OC in a real-world setting. Methods: This retrospective cohort study included pts with newly diagnosed stage III/IV epithelial OC who received 6–9 cycles of 1L platinum-based chemotherapy (PBC) and primary or interval debulking surgery following neoadjuvant chemotherapy between Jan 1, 2016, and Feb 29, 2020, from the nationwide Flatiron Health electronic health record–derived deidentified database. The end of the last cycle of 1L PBC was defined as the index date. Those pts who started second-line chemotherapy within 2 months of the index date were excluded. Logistic regression was used to analyze variables with regard to 1L maintenance use. Results: In total, 463 pts were included; 21% received maintenance therapy, 79% received active surveillance. Baseline characteristics are shown in the table. Overall maintenance therapy use increased over the study period, from 7.7% to 37.7%. Pts with BRCA wild type were significantly less likely to receive maintenance therapy (odds ratio [OR]: 0.30; 95% CI, 0.16–0.59) than pts with BRCA mutation. Pts treated in 2018 (OR: 2.73; 95% CI, 1.25–5.98) and 2019 (OR: 8.78; 95% CI, 4.15–18.55) were significantly more likely to receive maintenance therapy than pts treated in 2017. Age, race, practice type, ECOG score, and residual disease status were not significant predictors of 1L maintenance use. Conclusions: Nearly 40% of pts with advanced stage OC received upfront maintenance therapy with an increasing trend over time, particularly in those with biomarker guidance. Research is warranted toward addressing barriers to the appropriate use of maintenance therapy.[Table: see text]

Selection Of

Ovarian cancer is the seventh most common type of cancer and the fifth leading cause of cancer death among women worldwide. The current usual therapeutic approach in this disease includes optimal cytoreductive therapy followed by platinum-based adjuvant chemotherapy, along with neoadjuvant chemotherapy prior to surgery in selected cases. The platinum-free interval (PFI) continues to be the most useful tool to assist in the selection of the subsequent therapy and to predict response to treatment. The combination of trabectedin and pegylated liposomal doxorubicin (PLD) is useful in patients with partially platinum-sensitive recurrent ovarian cancer, in patients who have previously received two or more platinum-based chemotherapy regimens, in patients who have already experienced a platinum-induced hypersensitivity reaction and in patients who have previously failed to respond to a platinum-based treatment. Case Presentation: A 64-years-old postmenopausal woman with pain, abdominal distension, and an altered intestinal transit and with partially platinum-sensitive recurrent ovarian cancer, was successfully treated with a second line of trabectedin chemotherapy in combination with PLD, followed by trabectedin in monotherapy. This case proves the effectiveness of the combination of trabectedin and PLD and demonstrates how the administration of trabectedin, even in monotherapy, allows to maintain an adequate clinical response with good tolerance to the treatment during more than two years of drug administration.

Aim: To assess real-world occurrence of common clinical trial-reported adverse events (AE) among patients with recurrent ovarian cancer initiating niraparib 200 mg/day. Materials & methods: This retrospective observational study used physician-extracted anonymized medical record data of eligible patients initiating niraparib 200 mg/day after platinum-based chemotherapy. Results: Of 153 patients, 57 (37%) experienced ≥1 of the three most common all-grade AEs within 3 months after niraparib initiation: nausea (16%; grade 3/4: 2%), thrombocytopenia (14%; grade 3/4: 3%) and fatigue (24%; grade 3/4: 3%). In the ENGOT-OV16/NOVA trial, these respective AEs occurred in 74, 61 and 59% of patients. Conclusion: Incidence of common clinical trial-reported AEs was lower among patients initiating niraparib 200 mg/day in real-world practice versus patients initiating niraparib 300 mg/day in ENGOT-OV16/NOVA.
