PURPOSE This study estimated time without symptoms or toxicity (TWiST) with niraparib compared with routine surveillance (RS) in the maintenance treatment of patients with recurrent ovarian cancer. PATIENTS AND METHODS Mean progression-free survival (PFS) was estimated for niraparib and RS by fitting parametric survival distributions to Kaplan-Meier data for 553 patients with recurrent ovarian cancer who were enrolled in the phase III ENGOT-OV16/NOVA trial. Patients were categorized according to the presence or absence of a germline BRCA mutation—g BRCAmut and non-g BRCAmut cohorts. Mean time with toxicity was estimated based on the area under the Kaplan-Meier curve for symptomatic grade 2 or greater fatigue, nausea, and vomiting adverse events (AEs). Time with toxicity was the number of days a patient experienced an AE post–random assignment and before disease progression. TWiST was estimated as the difference between mean PFS and time with toxicity. Uncertainty was explored using alternative PFS estimates and considering all symptomatic grade 2 or greater AEs. RESULTS In the g BRCAmut and non-g BRCAmut cohorts, niraparib treatment resulted in a mean PFS benefit of 3.23 years and 1.44 years, respectively, and a mean time with toxicity of 0.28 years and 0.10 years, respectively, compared with RS. Hence, niraparib treatment resulted in a mean TWiST benefit of 2.95 years and 1.34 years, respectively, compared with RS, which is equivalent to more than four-fold and two-fold increases in mean TWiST between niraparib and RS in the g BRCAmut and non-g BRCAmut cohorts, respectively. This TWiST benefit was consistent across all sensitivity analyses, including modeling PFS over 5-, 10-, and 15-year time horizons. CONCLUSION Patients who were treated with niraparib compared with RS experienced increased mean TWiST. Thus, patients who were treated with niraparib in the ENGOT-OV16/NOVA trial experienced more time without symptoms or symptomatic toxicities compared with control.

Aim: Poly(ADP-ribose) polymerase inhibitors (PARPIs) improved progression-free survival among patients with recurrent ovarian cancer. This meta-analysis examined the effectiveness of PARPIs as maintenance strategy for newly diagnosed patients with advanced high-grade ovarian cancer with or without mutations. Materials & methods: Using defined selection criteria, a literature search identified four eligible randomized clinical trials involving 2386 patients. Results: Compared with placebo maintenance, PARPIs achieved a 46% reduction in the risk of progression or death as compared with placebo (hazard ratio: 0.54; 95% CI: 0.39–0.73; p < 0.0001). That benefit was shown in all clinical subgroups: among those with BRCA mutation, with negative/unknown BRCA mutation, and in those with homologous recombination deficient tumors. Data about the effect on overall survival are still premature. Conclusion: In patients with newly diagnosed advanced ovarian cancer, PARPIs maintenance after standard therapy achieved a significant improvement in progression-free survival as compared with placebo, overall and in all subgroups.

Objective: This study aimed to establish a pharmacodynamic model and to screen reasonable covariates to quantitatively describe the efficacy of poly (ADP-ribose) polymerase inhibitors (PARPis) as maintenance treatment for recurrent ovarian cancer (ROC).Methods: The log normal hazard function model was established by using progression-free survival (PFS) data of 1,169 patients from published randomized trials on FDA-approved PARP inhibitors (olaparib, niraparib, and rucaparib). Monte Carlo simulation was used to compare PFS values in different scenarios, such as monotherapy (administered alone) and combination therapy (PARPis combined with chemo- or target-therapies), different biomarker statuses, and different PARP inhibitors. PFS was also estimated.Results: The study showed that the median PFS was 8.5 months with monotherapy and 16.0 months with combination therapy. The median PFS of patients with the BRCA mutation, BRCA wild-type, and HRD-positivity were 11.0, 7.5, and 9.0 months in monotherapy, respectively, and 23.0, 14.0 and 17.5 months, in combination therapy, respectively. In addition, the median PFS of olaparib, niraparib, and rucaparib monotherapy were about 9.5, 10.5, and 12.0 months, respectively, and about 19.0, 20.0, and 25 months, respectively, in combination therapy. The median PFS values in combination with cediranib, bevacizumab, and chemotherapy were approximately 17.0, 12.5 and 19.5 months, respectively.Conclusion: PARPi combination therapy is more effective as maintenance treatment for ROC than monotherapy, and the efficacy of PARPis in combination with chemotherapy is higher than that of the combination with antiangiogenic drugs. We found that the PFS of BRCA wild-type was similar to that of HRD-positive patients, and there was no significant difference in PFS between olaparib, niraparib, and rucaparib, which provides necessary quantitative information for the clinical practice of PARPis in the treatment of ROC.

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.

The Cost

Purpose: Although the Food and Drug Administration has approved incorporation of bevacizumab (BEV) into the treatment of platinum-resistant ovarian cancer (PROC), cost-value measures are an essential consideration, as evidenced by the recent ASCO Value Framework initiative. We assessed the cost-effectiveness and reviewed the net health benefit (NHB) of this expensive treatment. Methods: A cost-effectiveness decision model was constructed using results from a phase III trial comparing BEV plus cytotoxic chemotherapy with chemotherapy alone in patients with PROC. The Avastin Use in Platinum-Resistant Epithelial Ovarian Cancer (AURELIA) trial demonstrated improvement in progression-free survival and quality of life in patients receiving BEV. Costs, paracentesis rates, and adverse events were incorporated, including subgroup analysis of different partner chemotherapy agents. Results: Inclusion of BEV in the treatment of platinum-resistant recurrent ovarian cancer meets the common willingness-to-pay incremental cost-effectiveness ratio (ICER) threshold of $100,000 per progression-free life-year saved (LYS) for 15-mg/kg dosing and approaches this threshold for 10-mg/kg dosing, with an ICER of $160,000. In sensitivity analysis, reducing the cost of BEV by 13% (from $9,338 to $8,100 per cycle) allows 10-mg/kg dosing to reach a $100,000 ICER. Exploratory analysis of different BEV chemotherapy partners showed an ICER of $76,000 per progression-free LYS (6.5-month progression-free survival improvement) and $54,000 per LYS (9.1-month overall survival improvement) for the addition of BEV to paclitaxel once per week. Using the ASCO framework for value assessment, the NHB score for BEV plus paclitaxel once per week is 48. Conclusion: Using a willingness-to-pay threshold of $100,000 ICER, the addition of BEV to chemotherapy either demonstrates or approaches cost-effectiveness and NHB when added to the treatment of patients with PROC.

We experienced a case of recurrent ovarian cancer that responded to weekly docetaxel. The patient had stage IIIC ovarian cancer (poorly differentiated serous adenocarcinoma). After initial remission was achieved by chemotherapy with paclitaxel and carboplatin plus cytoreductive surgery, the disease recurred and irinotecan therapy achieved temporary remission. During maintenance therapy with oral etoposide, the disease recurred again. We then tried five courses of weekly docetaxel therapy and it successfully controlled the disease. The progression-free survival time on weekly docetaxel treatment is now 7 months and the toxicity was extremely low. This patient demonstrates the effectiveness of weekly docetaxel as salvage chemotherapy for recurrent ovarian cancer.

PurposeThe management of recurrent ovarian cancer remains controversial. Single-agent topotecan is an established treatment option, and preliminary evidence suggests improved tumor control by combining topotecan with etoposide or gemcitabine.Patients and MethodsWomen with relapsed ovarian cancer after primary surgery and platinum-based chemotherapy were randomly assigned to topotecan monotherapy 1.25 mg/m2/d, topotecan 1.0 mg/m2plus oral etoposide 50 mg/d, or topotecan 0.5 mg/m2/d plus gemcitabine 800 mg/m2on day 1 and 600 mg/m2on day 8 every 3 weeks. Patients were stratified for platinum-refractory and platinum-sensitive disease according to a recurrence-free interval of less or more than 12 months, respectively. The primary end point was overall survival. Secondary end points included progression-free survival, objective response rates, toxicity, and quality of life (as measured by the European Organisation for Research and Treatment of Cancer [EORTC] 30-item Quality-of-Life Questionnaire).ResultsThe trial enrolled 502 patients with a mean age of 60.5 years (± 10.2 years), 208 of whom were platinum resistant. Median overall survival was 17.2 months (95% CI, 13.5 to 21.9 months) with topotecan, 17.8 months (95% CI, 13.7 to 20.0 months) with topotecan plus etoposide (log-rank P = .7647), and 15.2 months (95% CI, 11.3 to 20.9 months) with topotecan plus gemcitabine (log-rank P = .2344). Platinum-sensitive patients lived significantly longer than platinum-refractory patients (21.9 v 10.6 months). The median progression-free survival was 7.0, 7.8, and 6.3 months, respectively. Objective response rates were 27.8%, 36.1%, and 31.6%, respectively. Patients under combined treatment were at higher risk of severe thrombocytopenia.ConclusionNonplatinum topotecan combinations do not provide a survival advantage over topotecan alone in women with relapsed ovarian cancer.
