Abstract Purpose Poly (ADP-ribose) polymerase (PARP) inhibitor, is a milestone in treatment of ovarian cancer. However, there is no real world study from China regarding the clinical outcome of the taking PARP inhibitor (PARPi), Olaparib(Lynparza™). The goal of this research is to evaluate the side effects and short-term efficacy in advanced ovarian cancer patients who administered Olaparib. Methods Patients with ovarian cancer, fallopian tube cancer and peritoneal cancer that treated with Olaparib in The Affiliated Cancer Hospital of Nanjing Medical University between September 2018 and June 2019 were recruited. The drug associated Adverse Events (AEs) were collected and short-term efficacy were analyzed by modified Response Evaluation Criteria in Solid Tumors (mRECIST) . Results Of all 28 enrolled patients, 92.9% were ovarian cancer, 7.1% were fallopian tube cancer, and 39.3% cases harbored germline BRCA-mutation. There were 6(21.4%) patients received Olaparib after multi-line chemotherapy, and 10 patients (35.7%) as second-line maintenance therapy and 2 patients (7.1%) as first-line maintenance therapy. There were still other 10 cases (35.7%) received Olaparib as exploratory therapy. Abdominal distention, decreased blood pressure, increased body hair, thirsty, burning sensation of stomach and leg swelling were newly reported AEs. Serious Adverse Events(SAEs) were usually managed by dose interruption or dose reduction, rather than discontinuation. 3 patients discontinued treatment, 8 patients received reduced dose of Olaparib, and 4 patients stopped therapy after the alleviation of AEs. Of all 28 enrolled cases, in monotherapy group, 1 of 6 patients achieved stable disease(SD) and also 2 patients achieved stable disease(SD) combined with anti-angiogenic drugs when disease progressed. 2 patients achieved complete remission(CR) and 3 patients were stable with exploratory therapy. Conclusions The AEs of Olaparib were all manageable. For the first time, we also identified several AEs such as abdominal distention, decreased blood pressure, increased body hair, thirsty, burning sensation of stomach and leg swelling during the follow-up which have not been reported. The short-term efficacy was observed in some exploratory cases that provided new potential indication to PARPi-related clinical trials.

Phase Iii Trials

Poly(ADP-ribose) polymerase (PARP) inhibitor maintenance therapy is the latest breakthrough in the management of newly diagnosed advanced ovarian cancer. The results of the SOLO-1 trial in 2018 led to European Medicines Agency and Food and Drug Administration approval of olaparib as first-line maintenance therapy in patients with BRCA1/2 mutation, establishing a new standard of care. Subsequently, the results of three phase III trials (PRIMA, PAOLA-1, VELIA) evaluating the use of first-line PARP inhibitors beyond patients with BRCA1/2 mutations and as combination strategies were presented in 2019, leading to the recent approval of maintenance niraparib irrespective of biomarker status and olaparib in combination with bevacizumab in homologous recombination deficiency-positive-associated advanced ovarian cancer. An ESMO Open - Cancer Horizons round-table expert panel discussed the four phase III trials of first-line PARP inhibitor therapy and how they are changing the clinical management of advanced ovarian cancer.

Short Term Survival

Abstract Background Despite improvements in median survival some patients with advanced ovarian cancer die within 100 days of diagnosis; the reasons for which remain poorly understood. Here we investigate if ultra short-term survival can be explained by patient characteristics or treatment pathways. Methods A nested case comparison study was used to examine differences between patients with high grade serous ovarian/fallopian tube cancer who died within 100 days (n = 28) compared to a comparison group of patients matched for histology and including any survival greater than 100 days (n = 134). Results Cases and comparison patients had similar ages, BMI, ACE-27, deprivation indices, and distribution of disease on CT. There were no significant delays in time to diagnosis or treatment (p = 0.68) between the groups. However, cases had lower serum albumin, haemoglobin and higher platelet counts than matched comparison patients (p < 0.0001) and a worse performance score (P = 0.006). Conclusion Patients who die rapidly after a diagnosis of ovarian cancer are only slightly older and have similar pre treatment frailty compared to patients whose survival approaches the median. However they do appear to undergo greater physiological compromise as a result of their disease.

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]

PurposePazopanib is an oral, multikinase inhibitor of vascular endothelial growth factor receptor (VEGFR) -1/-2/-3, platelet-derived growth factor receptor (PDGFR) -α/-β, and c-Kit. Preclinical and clinical studies support VEGFR and PDGFR as targets for advanced ovarian cancer treatment. This study evaluated the role of pazopanib maintenance therapy in patients with ovarian cancer whose disease did not progress during first-line chemotherapy.Patients and MethodsNine hundred forty patients with histologically confirmed cancer of the ovary, fallopian tube, or peritoneum, International Federation Gynecology Obstetrics (FIGO) stages II-IV, no evidence of progression after primary therapy consisting of surgery and at least five cycles of platinum-taxane chemotherapy were randomized 1:1 to receive pazopanib 800 mg once per day or placebo for up to 24 months. The primary end point was progression-free survival by RECIST 1.0 assessed by the investigators.ResultsMaintenance pazopanib prolonged progression-free survival compared with placebo (hazard ratio [HR], 0.77; 95% CI, 0.64 to 0.91; P = .0021; median, 17.9 v 12.3 months, respectively). Interim survival analysis based on events in 35.6% of the population did not show any significant difference. Grade 3 or 4 adverse events of hypertension (30.8%), neutropenia (9.9%), liver-related toxicity (9.4%), diarrhea (8.2%), fatigue (2.7%), thrombocytopenia (2.5%), and palmar-plantar erythrodysesthesia (1.9%) were significantly higher in the pazopanib arm. Treatment discontinuation related to adverse events was higher among patients treated with pazopanib (33.3%) compared with placebo (5.6%).ConclusionPazopanib maintenance therapy provided a median improvement of 5.6 months (HR, 0.77) in progression-free survival in patients with advanced ovarian cancer who have not progressed after first-line chemotherapy. Overall survival data to this point did not suggest any benefit. Additional analysis should help to identify subgroups of patients in whom improved efficacy may balance toxicity (NCT00866697).
