e19174 Background: Despite clinical evidence illustrating the efficacy of MT for ROC, complexities, such as patient-, treatment-, and disease-related factors, and team-based care coordination, limit its optimal use in ROC. In a quality improvement (QI) program, conducted at 2 oncology systems, we evaluated gaps in evidence-based, quality ROC care. Methods: Between 09/2019-02/2020, retrospective EMR audits of 200 patients with ovarian cancer were analyzed for demographics, disease characteristics, treatment history, and shared decision-making (SDM) involving MT. Surveys were administered to evaluate challenges, barriers and experiences of healthcare professionals (HCP; N = 35) and their patients with ROC (N = 21). The HCP teams participated in audit-feedback sessions and developed action plans for resolving identified gaps. Results: EMR audits revealed low utility of MT among patients with ROC (Table), and only 20% of patients reported that MT was discussed as a treatment option. Lack of access to newer therapies was most commonly identified (27%) by HCP as the biggest challenge in treating patients with ROC. Furthermore, survey results revealed that HCP are challenged to correctly integrate guidelines for patient selection for PARP inhibitor MT based on BRCA mutation status (18% of HCP answered correctly), response to previous chemotherapy (49% correct), and line of therapy (46% correct). Data indicated a low level of SDM – none of the patients indicated a high level involvement in treatment decisions and only 20% indicated a high level of agreement that their care team understood their treatment goals. EMR audits also illustrate low documentation of multiple aspects of SDM (Table). Oncology team members formulated plans to develop guidance documents to assist in therapy sequencing and tools to improve patient education. Conclusions: Overall, data from this QI program indicate gaps, challenges, and barriers in evidence-based, MT decision-making and engagement of patients in SDM. These areas for improvement may be relevant for future interventions to improve the provision of quality ROC care. [Table: see text]

Evidence Based Decision Making

In today's cost challenged healthcare environment accountable care and evidence-based decision making have become important considerations. Contemporaneous to this is the fact that the superior management of diabetes has become a global priority especially given the exponential increase in the number of diabetes patients as well as the financial implications of treating this silent epidemic. Thus, this research focuses on trying to address these respective yet critical issues by examining the possibility of using a mobile web-based reporting system that taps into existing widely available resources to monitor and manage gestational diabetes. To test this solution, we adopted a randomized control trial with two-arm cross over applied to a not-for profit hospital in Victoria, Australia. From the perspective of practice, we have uncovered far reaching implications for hospital management's cost vs. quality care to patients. In particular, it appears that the adoption of smartphones to support many aspects of care and patient-clinician interactions is prudent.

Background/Objectives: BRCA mutation carriers and women at high risk of breast/ovarian cancer are faced with the intricate question to opt for prophylactic surgeries and/or a periodic screening. The aim of this study was therefore to identify objective and emotional factors that have an impact on the decision-making process. Methods: Ninety-five women with BRCA mutations or women at increased breast/ovarian cancer lifetime risk were counseled at our outpatient department and either opted for prophylactic surgery or periodic screening. To identify the psychological factors that could have influenced the decision-making, a standardized questionnaire was applied. Additionally, clinical data were collected and were reviewed by a personal talk. Results: Seventy-one of the patients opted for an increased surveillance only, 21 for prophylactic surgeries. Positive predictors for prophylactic surgeries were sociodemographic characteristics such as parity and objective variables such as verified mutation status. Hierarchical regression analysis revealed that the need for safety in health issues has been the only significant psychological predictor of surgery beyond the objective factors. Fear of surgical procedures, menopausal symptoms after surgery, loss of attractiveness, or fear of interferences with sexual life did not significantly affect decision-making. Conclusion: Decision-making towards prophylactic surgeries is influenced by objective but also emotional factors. Knowing that fear and anxiety also have an important impact on decision-making, distinct counselling about the procedures, the subsequent risk reduction as well as the psychological effects of prophylactic surgeries are essential.

Individual Gene

The presence of a BRCA mutation, somatic or germline, is now established as a standard of care for selecting patients with ovarian cancer for treatment with a PARP inhibitor. During the clinical development of the PARP inhibitor class of agents, a subset of women without BRCA mutations were shown to respond to these drugs (termed “ BRCAness”). It was hypothesized that other genetic abnormalities causing a homologous recombinant deficiency (HRD) were sensitizing the BRCA wild-type cancers to PARP inhibition. The molecular basis for these other causes of HRD are being defined. They include individual gene defects (e.g., RAD51 mutation, CHEK2 mutation), homozygous somatic loss, and whole genome properties such as genomic scarring. Testing this knowledge is possible when selecting patients to receive molecular therapy targeting DNA repair, not only for patients with ovarian cancer but also endometrial and cervical cancers. The validity of HRD assays and multiple gene sequencing panels to select a broader population of patients for treatment with PARP inhibitor therapy is under evaluation. Other non-HRD targets for exploiting DNA repair defects in gynecologic cancers include mismatch repair (MMR), checkpoint signaling, and nonhomologous end-joining (NHEJ) DNA repair. This article describes recent evidence supporting strategies in addition to BRCA mutation for selecting patients for treatment with PARP inhibitor therapy. Additionally, the challenges and opportunities of exploiting DNA repair pathways other than homologous recombination for molecular therapy in gynecologic cancers is discussed.

TPS5615 Background: BRCA1 and BRCA2 genes are critical in homologous recombination DNA repair and have been implicated in familial breast and ovarian cancer tumorigenesis. Tumor cells with these mutations demonstrate increased sensitivity to cisplatin and poly(ADP-ribose) polymerase (PARP) inhibitors. 6MP was identified in a screen for novel drugs and found to selectively kill BRCA-defective cells in a xenograft model as effectively as the PARP inhibitor, AGO14699, even after these cells had acquired resistance to a PARP inhibitor or cisplatin (Issaeva 2010). Exploiting the genetic basis of these tumours enables us to develop a more tailored approach to therapy for patients with BRCA mutated cancers. This multi-center phase II single arm trial was set up to investigate the activity and safety of 6MP with methotrexate in patients with breast or ovarian cancer who are known to have a BRCA mutation. Methods: Two-stage Simon compromise design (Jung 2001, Jung 2004) with α=0.20, power=90% to detect an increase in activity from 10 to 20%. 1st stage: if ≤ 3/30 evaluable patients respond at 8 weeks the trial will be stopped for futility; 2nd stage: if ≥9/65 evaluable patients respond at 8 weeks the treatment will be regarded as potentially effective and a phase III trial will be considered if the treatment appears safe and well-tolerated. 65 patients with BRCA defective cancer progressing after at least one prior chemotherapy or relapsed platinum resistant ovarian cancer, ECOG performance status 0-2 will be recruited and treated with daily 6MP (75mg/m2 ) and weekly methotrexate (20mg/m2) until progression. The starting dose was later reduced by 25% due to excess of expected toxicity. Patients with low TPMT activity or a low/low genotype are excluded due to the risk of increased toxicity. Prior treatment with a PARP inhibitor is permissible. Primary outcome: objective response at 8 weeks: complete, partial response or stable disease defined by RECIST 1.1. Secondary outcomes include safety, PFS, OS and quality of life. Of the 46 patients screened for TMPT activity between 15 Jun2009 and 05Dec 2012 from 12 UK sites, 31 patients were recruited. The pre-specified activity goal for the 1st stage was met and accrual into the 2nd stage continues. Clinical trial information: 2009-016846-16.

First Line Treatment

TPS5598 Background: Ovarian cancer (OC) is the leading cause of death from gynecologic cancers in US women. Despite high response rates to first-line treatment, ~70% of patients (pts) relapse within 3 years and then remain largely incurable. First-line treatment needs to be improved to achieve long-term remission in pts and improve the cure rate. The Phase III SOLO1 trial showed a meaningful clinical benefit for olap maintenance therapy in newly diagnosed OC pts with a BRCA mutation (Moore et al N Engl J Med 2018). Preliminary data suggest that combining a PD-L1 inhibitor, anti-angiogenic and PARP inhibitor (triplet therapy) may achieve a synergistic antitumor effect. The DUO-O study (NCT03737643) evaluates the efficacy and safety of treatment combinations involving standard-of-care platinum-based chemotherapy (chemo), VEGF inhibitor bev, anti-PD-L1 antibody durva and PARP inhibitor olap, in women with newly diagnosed advanced OC. Methods: Eligible pts for this double-blind, randomized, Phase III study must have newly diagnosed, advanced, high-grade epithelial OC and either have completed primary surgery or plan to have interval debulking surgery. Depending on their tumor BRCA mutation (tBRCAm) status (determined by central test), pts will join one of two independent cohorts. Pts in the non-tBRCAm cohort (n~906) will be randomized (1:1:1) before cycle 2 to: a) chemo + bev + placebo (for 6 cycles) followed by bev (15 mg/kg [total 15 months]) + placebo maintenance treatment (IV and tablets); b) chemo + bev + durva (6 cycles) followed by bev + durva (1120 mg q3w [total 15 months]) + placebo (tablets) maintenance treatment; or c) chemo + bev + durva (6 cycles) followed by bev + durva + olap (300 mg bd tablets [24 months]) maintenance treatment. Pts in the open-label tBRCAm cohort (n~150) will receive 6 cycles of chemo + durva followed by durva + olap maintenance therapy, with optional use of bev. The primary endpoint of progression-free survival will be assessed by modified RECIST 1.1. Key secondary endpoints include overall survival, overall response rate and duration of response. Enrollment began in January 2019. Clinical trial information: NCT03737643.

Abstract Background Niraparib, a poly (ADP-ribose) polymerase (PARP) inhibitor, is approved for first/second-line maintenance treatment of ovarian cancer patients with complete or partial response to platinum-based chemotherapy, and multi-line monotherapy in BRCAmt patients or platinum-sensitive recurrence patients with homologous recombination deficiency (HRD). We present real-world experience from a single center of China. Methods Patients treated with niraparib in Jiangsu Cancer Hospital between June 2019 to July 2020 were recruited. The initial dose was given according to individualization. Response and adverse events (AEs) were analyzed by Response Evaluation Criteria in Solid Tumors v1.1. and National Cancer Institute Common Terminology Criteria for Adverse Events v5.0, respectively. HRD testing (AmoyDx®) was detected in most patients. Treatment was given until unequivocal progression or intolerable toxicity. Results Twenty-two patients all received niraparib at a bolus of 200 mg/d. Fifty percent of patients with high-grade serous ovarian cancer are HRD-positive. Six patients underwent first-line maintenance therapy. Sixteen patients received exploratory therapy. Ultimately image evaluation revealed that two patients achieved partial response (PR) and one patient achieved stable disease (SD), yielding objective response rate (ORR) of 33.3% (95%CI = 0.060–0.759) and disease control rate (DCR) of 50% (95%CI = 0.140–0.861) in the exploratory multi-line monotherapy group. The most common AEs were nausea, thrombocytopenia, and anemia. Grade 3–4 thrombocytopenia were managed by dose reduction and interruption. Leg swelling was observed as a new adverse event. Conclusion It is feasible that patients receiving a bolus of 200 mg/d in patients from Chinese population can acquire promising efficacy and tolerance. This is the first real-world data about niraparib in ovarian cancer patients with available HRD status from China.

Significant Efficacy

Poly (ADP-ribose) polymerase (PARP) inhibitors are a novel class of therapeutic agents that target tumors with deficiencies in the homologous recombination DNA repair pathway. Genomic instability characterizes high-grade serous ovarian cancer (HGSOC), with one half of all tumors displaying defects in the important DNA repair pathway of homologous recombination. Early studies have shown significant efficacy for PARP inhibitors in patients with germline breast related cancer antigens 1 and 2 (BRCA1/2) mutations. It has also become evident that BRCA wild-type patients with other defects in the homologous recombination repair pathway benefit from this treatment. Companion homologous recombination deficiency (HRD) scores are being developed to guide the selection of patients that are most likely to benefit from PARP inhibition. The choice of which PARP inhibitor is mainly based upon the number of prior therapies and the presence of a BRCA mutation or HRD. The identification of patients most likely to benefit from PARP inhibitor therapy in view of HRD and other biomarker assessments is still challenging. The aim of this review is to describe the current evidence for PARP inhibitors in ovarian cancer, their mechanism of action, and the outstanding issues, including the rate of long-term toxicities and the evolution of resistance.

6002 Background: SOLO2 (ENGOT ov-21; NCT01874353) showed that maintenance therapy with the PARP inhibitor olaparib in pts with platinum-sensitive relapsed ovarian cancer (PSROC) and a BRCA mutation (BRCAm) led to a statistically significant improvement in median progression-free survival (PFS) of 13.6 months vs placebo (hazard ratio [HR] 0.30). Time to second progression or death significantly improved (Pujade-Lauraine et al Lancet Oncol 2017) and a quality-adjusted PFS benefit was seen (Friedlander et al Lancet Oncol 2018) with maintenance olaparib vs placebo. We report the preplanned final OS analysis for SOLO2. Methods: Pts with PSROC and a BRCAm who had received ≥2 lines of treatment and were in response to their most recent platinum-based chemotherapy received maintenance olaparib (300 mg bid tablets) or placebo. Pts were stratified by response to previous chemotherapy (complete vs partial) and length of platinum-free interval (>6–12 months vs >12 months). OS was a secondary endpoint. The only preplanned OS sensitivity analysis was an OS analysis in the Myriad germline BRCAm subset (Myriad BRAC Analysis test). Results: At final data cut-off (Feb 3, 2020), median follow-up was 65 months in both treatment arms. A long-term treatment benefit was seen with olaparib vs placebo with an OS HR of 0.74 (95% confidence interval [CI] 0.54–1.00) in the full analysis set (FAS; unadjusted for crossover; 38.4% of placebo pts crossed over to a PARP inhibitor) (Table). At 5 years: by Kaplan-Meier estimates, 28.3% of pts in the olaparib arm vs 12.8% of pts in the placebo arm were alive and had still not received subsequent treatment; 42.1% of olaparib pts vs 33.2% of placebo pts were alive. The long-term tolerability profile of olaparib was generally consistent with that reported previously. Conclusions: In the final analysis of SOLO2, maintenance olaparib provided an unprecedented improvement of 12.9 months in median OS vs placebo. This is the first study with olaparib tablets, and the first since Study 19 (NCT00753545), to provide long-term follow-up and final OS data in pts with PSROC and a BRCAm. Clinical trial information: NCT01874353. [Table: see text]
