Systematic nurse-led consultations based on electronic patient-reported outcomes for women with endometrial or ovarian cancer during chemotherapy—a feasibility study

Abstract Purpose This study aimed to investigate the feasibility of nurse-led consultations based on ePRO for women with endometrial or ovarian cancer receiving chemotherapy. Methods This was a prospective single-cohort feasibility study. The patients responded to weekly ePRO using the Elekta Kaiku platform, which was adapted to Danish. At selected time points during chemotherapy, nurses conducted nurse-led consultations replacing physicians. The primary outcome was the patient completion rate of ePRO reporting in the Elekta Kaiku platform. Secondary outcomes included assessing safety, acceptability, practicability, usability, patient satisfaction with ePRO, and patient symptom burden. Results Twenty patients were included, with a mean age of 59 years. A total of 320 ePRO reports were received, equivalent to an ePRO response of 18 times per patient during six cycles of chemotherapy. The results showed a high weekly completion rate (87%), high patient satisfaction with ePRO, and a continuous high symptom burden. Nurse-led consultations achieved a success rate of 55% in adhering to scheduled appointments. The primary contributing factors to this issue were the inadequate internal workflows and the complex symptom burden experienced by the patients. Conclusion This study indicates that weekly ePRO reporting in conjunction with nurse-led consultations may be feasible in this population. The use of ePRO revealed a high level of symptoms reported by patients throughout the treatment cycles. The results emphasize the importance of clinicians in proactively and systematically intervening at an early stage to prevent symptom escalation. However, the small sample size limits the generalizability of this study. Trial registration This study was registered at the Capital Region of Denmark (P-2021–179) and approved the 10/03/2021.

GOG-3097/ENGOT-ov81/GTG-UK/RAMP 301: a phase 3, randomized trial evaluating avutometinib plus defactinib compared with investigator’s choice of treatment in patients with recurrent low grade serous ovarian cancer

There are no approved treatments specifically for low grade serous ovarian cancer; current standard of care treatment options are limited in efficacy and tolerability. The combination of avutometinib with defactinib has demonstrated efficacy and a consistent safety profile in two clinical trials in recurrent low grade serous ovarian cancer, and a lower discontinuation rate due to adverse events compared with historical rates for standard of care. To compare the progression-free survival of the combination of avutometinib with defactinib versus investigator's choice of treatment in patients with recurrent low grade serous ovarian cancer. Combination treatment with avutometinib-defactinib will significantly improve progression-free survival compared with investigator's choice of treatment in patients with recurrent low grade serous ovarian cancer. GOG-3097/ENGOT-ov81/GTG-UK/RAMP 301 is a phase 3, randomized, international, open-label study designed to compare avutometinib with defactinib versus investigator's choice of treatment in patients with recurrent low grade serous ovarian cancer who have progressed on a previous platinum-based therapy. On confirmation of disease progression using a blinded independent central review, patients on the investigator's choice of treatment arm may cross over to the avutometinib-defactinib arm. Patients must have recurrent low grade serous ovarian cancer (KRAS mutant or wild-type) and have documented progression (radiographic or clinical) or recurrence of low grade serous ovarian cancer after at least one platinum-based chemotherapy regimen. Unlimited additional previous lines of therapy are allowed, including previous MEK/RAF inhibitor. Patients will be excluded if they have co-existing high grade ovarian cancer or had previous treatment with avutometinib, defactinib, or any other FAK inhibitor. Progression-free survival according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, blinded-independent central review. Approximately 270 patients will be randomized in a 1:1 fashion to either the combination avutometinib with defactinib arm (n∼135) or the investigator's choice of treatment arm (n∼135). The estimated primary completion date of RAMP 301 is 2028, and the estimated study completion date is 2031. ClinicalTrials.gov NCT06072781.

ENGOT-EN20/GOG-3083/XPORT-EC-042 – A phase III, randomized, placebo-controlled, double-blind, multicenter trial of selinexor in maintenance therapy after systemic therapy for patients with p53 wild-type, advanced, or recurrent endometrial carcinoma: rationale, methods, and trial design

Poor Concordance Between Cancer Antigen-125 and RECIST Assessment for Progression in Patients With Platinum-Sensitive Relapsed Ovarian Cancer on Maintenance Therapy With a Poly(ADP-ribose) Polymerase Inhibitor

PURPOSE Cancer antigen-125 (CA-125) is recommended by treatment guidelines and widely used to diagnose ovarian cancer recurrence. The value of CA-125 as a surrogate for disease progression (PD) and its concordance with radiologic progression are unclear, particularly for women with platinum-sensitive relapsed ovarian cancer (PSROC) who have responded to chemotherapy and treated with maintenance poly(ADP-ribose) polymerase inhibitor (PARPi). METHODS In this pooled analysis of four randomized trials of maintenance PARPi or placebo (Study 19, SOLO2, ARIEL3, and NOVA), we extracted data on CA-125 PD as defined by Gynecologic Cancer InterGroup criteria and RECIST v1.1. We evaluated the concordance between CA-125 and RECIST PD and reported on the negative predictive value (NPV) and positive predictive value (PPV). RESULTS Of 1,262 participants (n = 818 PARPi, n = 444 placebo), 403 (32%) had CA-125 PD, and of these, 366 had concordant RECIST PD (PPV, 91% [95% CI, 88 to 93]). However, of 859 (68%) without CA-125 PD, 382 also did not have RECIST PD (NPV, 44% [95% CI, 41 to 48]). Within the treatment arms, PPV remained high (PARPi, 91% [95% CI, 86 to 94]; placebo, 91% [95% CI, 86 to 95]) but NPV was lower on placebo (PARPi, 53% [95% CI, 49 to 57]; placebo, 25% [95% CI, 20 to 31]). Of 477 with RECIST-only PD, most (95%) had a normal CA-125 at the start of maintenance therapy and the majority (n = 304, 64%) had CA-125 that remained within normal range. Solid organ recurrence without peritoneal disease was more common in those with RECIST-only PD than in those with CA-125 and RECIST PD (36% v 24%; P < .001). CONCLUSION In patients with PSROC treated with maintenance PARPi, almost half with RECIST PD did not have CA-125 PD, challenging current guidelines. Periodic computed tomography imaging should be considered as part of surveillance, particularly in those with a normal CA-125 at the start of maintenance therapy and on treatment.

Implementing MyChoice® CDx HRD testing for the Nordics: lessons from 2021 to 2023

Background: Assessment of homologous recombinant deficient (HRD) phenotypes is key for managing Poly (ADP-ribose) polymerase inhibitor (PARPi) treatment. To accommodate the need for a validated HRD platform and enhance targeted treatment of ovarian cancer patients, a Nordic core facility for the myChoice® CDx platform was established in Denmark. Materials and methods: Comparative calculations and statistics are based on information from test requisitions and results (Genome Instability Score [GIS], BRCA status and combined HRD status) obtained from ovarian and breast cancer samples submitted for HRD-testing by myChoice® CDx through the Nordic core facility in the 2-year period. Results: Copenhagen University Hospital received 1,948 requisitions during the 2-year period. Conclusive results were obtained in 89% of the tests, while 7% were inconclusive due to the lack of GIS and 4% were not able to be analysed. Comparing the conclusive HRD status results across countries, Sweden had the highest percentage of HRD positives (38%) compared to Denmark, Norway, and Finland (28–32%). Interpretation: The myChoice® CDx Nordic core facility has been well received among the Nordic countries and provides new insights on the influence of national guidelines on HRD testing. Overall, we experienced an efficient turnaround time and a high fraction of conclusive results. Interestingly, prior somatic BRCA testing is redundant when assessing HRD status through myChoice® CDx test since somatic BRCA screening is already a significant component of the myChoice® CDx test. Thus, it should be considered to omit prior somatic BRCA testing to ensure a rationalised HRD diagnostic flow optimised for clinical use.

Combining Homologous Recombination-Deficient Testing and Functional RAD51 Analysis Enhances the Prediction of Poly(ADP-Ribose) Polymerase Inhibitor Sensitivity

PURPOSE To meet the urgent need for accessible homologous recombination-deficient (HRD) test options, we validated a laboratory-developed test (LDT) and a functional RAD51 assay to assess patients with ovarian cancer and predict the clinical benefit of poly(ADP-ribose) polymerase inhibitor therapy. METHODS Optimization of the LDT cutoff and validation on the basis of samples from 91 patients enrolled in the ENGOT-ov24/NSGO-AVANOVA1&2 trial (ClinicalTrials.gov identifier: NCT02354131 ), previously subjected to commercial CDx HRD testing (CDx). RAD51 foci analysis was performed and tumors with ≥five foci/nucleus were classified as RAD51-positive (homologous recombination-proficient). RESULTS The optimal LDT cutoff is 54. Comparing CDx genome instability score and LDT HRD scores show a Spearman's correlation of rho = 0.764 ( P < .0001). Cross-tabulation analysis shows that the sensitivity of the LDT HRD score is 86% and of the LDT HRD status is 91.8% (Fisher's exact test P < .001). Survival analysis on progression-free survival (PFS) of LDT-assessed patients show a Cox regression P < .05. RAD51 assays show a correlation between low RAD51 foci detection (<20% RAD51+ cells) and significantly prolonged PFS ( P < .001). CONCLUSION The robust concordance between the open standard LDT and the CDx, especially the correlation with PFS, warrants future validation and implementation of the open standard LDT for HRD testing in diagnostic settings.

Optimizing disease progression assessment using blinded central independent review and comparing it with investigator assessment in the PRIMA/ENGOT-ov26/GOG-3012 trial: challenges and solutions

Progression-free survival is an established clinically meaningful endpoint in ovarian cancer trials, but it may be susceptible to bias; therefore, blinded independent centralized radiological review is often included in trial designs. We compared blinded independent centralized review and investigator-assessed progressive disease performance in the PRIMA/ENGOT-ov26/GOG-3012 trial examining niraparib monotherapy. PRIMA/ENGOT-ov26/GOG-3012 was a randomized, double-blind phase 3 trial; patients with newly diagnosed stage III/IV ovarian cancer received niraparib or placebo. The primary endpoint was progression-free survival (per Response Evaluation Criteria in Solid Tumors [RECIST] v1.1), determined by two independent radiologists, an arbiter if required, and by blinded central clinician review. Discordance rates between blinded independent centralized review and investigator assessment of progressive disease and non-progressive disease were routinely assessed. To optimize disease assessment, a training intervention was developed for blinded independent centralized radiological reviewers, and RECIST refresher training was provided for investigators. Discordance rates were determined post-intervention. There was a 39% discordance rate between blinded independent centralized review and investigator-assessed progressive disease/non-progressive disease in an initial patient subset (n=80); peritoneal carcinomatosis was the most common source of discordance. All reviewers underwent training, and as a result, changes were implemented, including removal of two original reviewers and identification of 10 best practices for reading imaging data. Post-hoc analysis indicated final discordance rates between blinded independent centralized review and investigator improved to 12% in the overall population. Median progression-free survival and hazard ratios were similar between blinded independent centralized review and investigators in the overall population and across subgroups. PRIMA/ENGOT-ov26/GOG-3012 highlights the need to optimize blinded independent centralized review and investigator concordance using early, specialized, ovarian-cancer-specific radiology training to maximize validity of outcome data.

The promise of combining CDK4/6 inhibition with hormonal therapy in the first-line treatment setting for metastatic or recurrent endometrial adenocarcinoma

Metastatic or recurrent endometrioid adenocarcinoma of the uterine corpus is often incurable with limited treatment options. First-line treatment often includes cytotoxic chemotherapy, which incurs significant toxicities for many patients. Endometrial cancer, specifically endometrioid cancer, is a hormone-sensitive disease and, while single-agent hormonal therapies have demonstrated clinical benefit, resistance to these agents often leads to the use of chemotherapy. There is a lack of approved endocrine treatment options in the metastatic setting for most recurrent endometrial cancers, representing an unmet clinical need. Emerging evidence suggests that hormonal therapy in combination with other targeted treatments, such as cyclin dependent kinase (CDK)4/6 inhibitors, is well tolerated and effective in select patient populations. We discuss the clinical evidence suggesting that the combination of CDK4/6 inhibitors and hormonal therapy has the potential to represent an important addition to the first-line treatment options for patients with low-grade advanced or recurrent endometrial cancer.

Management of endometrial cancer in Latin America: raising the standard of care and optimizing outcomes

Molecular characterization of endometrial cancer is allowing for increased understanding of the natural history of tumors and paving a more solid pathway for novel therapies. It is becoming increasingly apparent that molecular classification is superior to histological classification in terms of reproducibility and prognostic discrimination. In particular, the Proactive Molecular Risk Classifier for Endometrial Cancer allows classification of endometrial cancer into groups very close to those determined by the Cancer Genome Atlas Research Network—that is, DNA polymerase epsilon-mutated, mismatch repair-deficient, p53 abnormal, and non-specific molecular profile tumors. The transition from the chemotherapy era to the age of targeted agents and immunotherapy, which started later in endometrial cancer than in many other tumor types, requires widespread availability of specialized pathology and access to novel agents. Likewise, surgical expertise and state-of-the-art radiotherapy modalities are required to ensure adequate care. Nevertheless, Latin American countries still face considerable barriers to implementation of international guidelines. As we witness the dawn of precision medicine as applied to endometrial cancer, we must make continued efforts towards improving the quality of care in this region. The current article discusses some of these challenges and possible solutions.

A multi-method approach to selecting PRO-CTCAE symptoms for patient-reported outcome in women with endometrial or ovarian cancer undergoing chemotherapy

Abstract Background Women with endometrial or ovarian cancer experience a variety of symptoms during chemotherapy. Patient-Reported outcomes (PROs) can provide insight into the symptoms they experience. A PRO tool tailored to this patient population can help accurately monitor adverse events and manage symptoms. The objective of this study was to identify items in the National Cancer Institute’s measurement system Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE®) appropriate for use in a PRO tool for a population of women with endometrial or ovarian cancer undergoing treatment with taxanes (paclitaxel or docetaxel) in combination with carboplatin. Methods A two-phase, sequential multi-methods approach was applied. In phase one, a comprehensive literature search was done to map the toxicity of the applied chemotherapeutics and phase III clinical studies. Phase two, which comprised selecting the PRO-CTCAE items, included discussions with and feedback from a patient advisory board, an additional literature search, and focus group interviews with senior oncologists and specialized oncology nurses. A national expert panel facilitated both phases in terms of carefully select items from the PRO-CTCAE library. Results Phase one identified 18 symptoms and phase two, three additional ones, leading to the inclusion of 21 PRO-CTCAE symptoms in the final PRO tool. Since PRO-CTCAE also contains one to three sub-questions on the frequency, severity, and interference with daily activities of symptoms, there were 44 potential items. Conclusions This study describes taking a multi-method approach to selecting items from the PRO-CTCAE library for use in a population of women with endometrial or ovarian cancer undergoing chemotherapy. By systematically combining diverse approaches, we carefully selected 21 clinically relevant symptoms covered by 44 items in the PRO-CTCAE library. Future studies should investigate the psychometric properties of this PRO tool for women with endometrial or ovarian cancer.

Molecular Results and Potential Biomarkers Identified from the Phase 3 MILO/ENGOT-ov11 Study of Binimetinib versus Physician Choice of Chemotherapy in Recurrent Low-Grade Serous Ovarian Cancer

Abstract Purpose: We present the results of a post hoc tumor tissue analysis from the phase 3 MILO/ENGOT-ov11 study (NCT01849874). Patients and Methods: Mutation/copy-number analysis was performed on tissue obtained pre-randomization. The Kaplan–Meier method was used to estimate progression-free survival (PFS). Unbiased univariate analysis, Cox regression, and binary logistic regression were used to test associations between mutation status and outcomes, including PFS and binary response by local RECIST 1.1. Results: MILO/ENGOT-ov11 enrolled 341 patients, ranging in age from 22 to 79, from June, 2013 to April, 2016. Patients were randomized 2:1 to binimetinib or physician's choice of chemotherapy (PCC). The most commonly altered gene was KRAS (33%). In 135 patients treated with binimetinib with response rate (RR) data, other detected MAPK pathway alterations included: NRAS (n = 11, 8.1%), BRAF V600E (n = 8, 5.9%), RAF1 (n = 2, 1.5%), and NF1 (n = 7, 5.2%). In those with and without MAPK pathway alterations, the RRs with binimetinib were 41% and 13%, respectively. PFS was significantly longer in patients with, compared with those without, MAPK pathway alterations treated with binimetinib [HR, 0.5; 95% confidence interval (CI) 0.31–0.79]. There was a nonsignificant trend toward PFS improvement in PCC-treated patients with MAPK pathway alterations compared with those without (HR, 0.82; 95% CI, 0.43–1.59). Conclusions: Although this hypothesis-generating analysis is limited by multiple testing, higher RRs and longer PFS were seen in patients with low-grade serous ovarian cancer (LGSOC) treated with binimetinib, and to a lesser extent in those treated with PCC, who harbored MAPK pathway alterations. Somatic tumor testing should be routinely considered in patients with LGSOC and used as a future stratification factor.

Identifying high-risk relapse in early-stage I to II ovarian cancer using the CA125 ELIMination rate constant K (KELIM) score: a Gynecologic Cancer InterGroup individual patient-data meta-analysis

Despite curative surgery and adjuvant chemotherapy, a significant number of early stage I to II ovarian cancers relapse. The CA125 ELIMination rate constant K (KELIM) is a pragmatic indicator of tumor intrinsic chemosensitivity in advanced epithelial ovarian cancer. We assessed the prognostic value of KELIM in patients with early-stage ovarian cancer, with respect to 5-year recurrence-free survival and overall survival, using the Meta-Analysis in Ovarian Cancer, which is the Gynecologic Cancer InterGroup individual patient-data meta-analysis of randomized trials evaluating different adjuvant chemotherapy regimens. Individual patient KELIM values were previously estimated in 5884 patients from the Meta-Analysis in Ovarian Cancer. The prognostic value of KELIM was assessed using univariable & multivariable analyses in patients with resected International Federation of Gynecology and Obstetrics stage I and II disease. Overall, 1143 patients were identified, including clear cell (46.7%); serous (23.7%); endometrioid (12.4%); and mucinous carcinomas (3.9%). In multivariable analyses, a favorable KELIM score (≥1.0) was associated with higher 5-year recurrence-free survival (68.3% vs 55.9%; HR 0.61, 95% CI 0.48 to 0.77) and 5-year overall survival (80.7% vs 72.8%; HR 0.50, 95% CI 0.36 to 0.68), as was the histological sub-type. In exploratory analyses, KELIM score was a prognostic factor regarding 5-year recurrence-free survival and overall survival across all sub-types (especially clear cell carcinoma and serous, with HR ranging from 0.45 to 0.63) with baseline CA125 ≥15 IU/L, except for mucinous histology. The pragmatic KELIM score is an independent prognostic factor in patients with a non-mucinous stage I to II ovarian cancer optimally resected and treated with adjuvant chemotherapy. KELIM may help identify the patients at higher risk of relapse and death requiring closer follow-up or treatment intensification.

Potential Synergistic Effect between Niraparib and Statins in Ovarian Cancer Clinical Trials

Abstract This study investigates the potential clinical synergy between the PARP inhibitor niraparib (Zejula) and concomitant statins, exploring their combined effects on progression-free survival (PFS) in patients with ovarian cancer. We retrospectively analyzed niraparib registrational clinical trials in ovarian cancer to investigate potential interactions between niraparib and statins. In the PRIMA trial, patients receiving niraparib demonstrated improved PFS compared with those on placebo (HR = 0.62; P < 0.001; median PFS 13.8 vs. 8.2 months). The post hoc analysis revealed that patients receiving maintenance niraparib who reported concomitant use of statins exhibited significantly improved PFS compared with those on placebo with concomitant statins (HR = 0.34; P < 0.001; median PFS 18.2 vs. 6.0 months). Notably, the improved efficacy in the two-arm comparison of concomitant statin patients was much better than that in the two-arm comparison of those patients without statin, as reflected in the niraparib–statin interaction (P = 0.005). These findings suggest novel opportunities in oncology for the use of statins in combination therapies with PARP inhibitors and emphasize the need for further investigation. Significance: The presented retrospective analysis suggests, to the best of our knowledge for the first time, a potential significant interaction between statins and niraparib in clinical settings. Nevertheless, further investigations are required to gain a better understanding of the potential clinical benefit.

Beyond HRD Status: Unraveling Genetic Variants Impacting PARP Inhibitor Sensitivity in Advanced Ovarian Cancer

Abstract The management of advanced epithelial ovarian cancer (AOC) has undergone significant advancements with the emergence of molecular diagnostics, particularly in predicting responses to PARP inhibitors (PARPi) based on homologous recombination deficiency (HRD) status. However, understanding sensitivity and resistance beyond HRD status remains elusive. This study aims to explore molecular factors that may elucidate why HRD status does not consistently predict PARPi sensitivity. Therefore, we conducted a post hoc translational analysis of formalin-fixed paraffin-embedded tumor samples from the ENGOT-ov24/NSGO-AVANOVA part 1 and 2 trial (NCT02354131), focusing on alterations pertaining radiologic response and progression-free survival (PFS). DNA sequencing was performed using the TruSight Oncology 500 HT gene panel, with variants classified according to recent guidelines. HRD status had been assessed by Myriad MyChoice CDx. We identified, among 92 patients in the ENGOT-ov24/NSGO-AVANOVA part 1 and 2 trial, 151 pathogenic or likely pathogenic variants across 81 samples. PARPi-sensitizing variants were found in two out of 10 HRD-negative samples from patients with clinical benefit (PFS ≥12 months), whereas three out of 10 HRD-positive samples from patients having no benefit (PFS ≤6 months) harbored variants associated with PARPi resistance. Additionally, analysis of BRCA1 variants revealed that truncating variants in exon 11 correlated with clinical benefit when niraparib was combined with bevacizumab. Conclusively, our findings highlight the complexity of PARPi response in AOC and underscore the importance of exploring somatic variants beyond HRD status. Further investigation into exon 11 variants of BRCA1 and the potential of combination treatment is warranted. Significance: The irregular response to PARPi in HRD-positive and -negative tumors highlights the need for identifying additional biomarkers. This study explores the mutational landscape beyond HRD status in AOC, ultimately advancing precision oncology in future clinical practice.

Impact of metformin, statins, and beta blockers on survival in patients with primary ovarian cancer: combined analysis of four prospective trials of AGO-OVAR and ENGOT/GCIG collaborators

The aim of this study was to investigate the association of co-medication with metformin, a statin, or beta blocker with survival in patients with primary ovarian cancer. Individual data from three phase III, randomized controlled trials (AGO-OVAR 11, AGO-OVAR 12, and AGO-OVAR 16) and one phase II trial (AGO-OVAR 15) were pooled and analyzed. Patients were classified as ever user if the specific co-medication was documented at least once during the trial, and were compared with never users as controls. Association of co-medications and outcomes were adjusted for potential confounders (age, International Federation of Gynecology and Obstetrics stage, histology, residual disease after surgery, Eastern Cooperative Oncology Group (ECOG) performance status, body mass index, Charlson Comorbidity Index, and assigned treatment within the trial) in multivariate Cox regression analyses. Overall, n=2857 patients were included. Ever users were: 100 patients received metformin (3.5%), 226 patients received statins (7.9%), and 475 (16.6%) patients received beta blockers (n=391 selective beta blockers; 84 non-selective beta blockers) as co-medication. There were no significant differences regarding the baseline characteristics except that ever users were significantly older, more obese, and had more comorbidities, according to the Charlson Comorbidity Index, compared with controls. Multivariate analyses for progression free survival and overall survival revealed neither a significant impact of metformin on survival (progression free survival hazard ratio (HR) 0.94, 95% confidence interval CI 0.69 to 1.29, p=0.7; overall survival HR 0.82, 95% CI 0.58 to 1.17, p=0.28) nor for statins (progression free survival HR 0.98, 95% CI 0.82 to 1.18, p=0.87; overall survival HR 0.91, 95% CI 0.74 to 1.12, p=0.37). In contrast, ever users of selective beta blockers had a significantly higher risk for recurrence and death (progression free survival HR 1.22, 95% CI 1.05 to 1.41, p=0.009; overall survival HR 1.25 95% CI 1.06 to 1.47, p=0.009). In this analysis, co-medication with metformin or statins had no significant impact on survival in patients with primary ovarian cancer. In contrast, co-medication with a beta blocker was associated with worse survival. However, whether this observation is related to the underlying condition rather than a direct negative impact on tumor biology remains unclear.

A Study of Avutometinib (VS-6766) + Defactinib (VS-6063) in Recurrent Low-Grade Serous Ovarian Cancer

This study will assess the safety and efficacy of avutometinib (VS-6766) in combination with defactinib versus Investigator's choice of treatments (ICT) in subjects with recurrent LGSOC who have progressed on a prior platinum-based therapy.

Selinexor in Maintenance Therapy After Systemic Therapy for Participants With p53 Wild-Type, Advanced or Recurrent Endometrial Carcinoma

The purpose of this study is to evaluate the efficacy and safety of selinexor as a maintenance treatment in patients with p53 wt endometrial carcinoma (EC), who have achieved a partial response (PR) or complete response (CR) (per Response Evaluation Criteria in Solid Tumors version 1.1 \[RECIST v 1.1\]) after completing at least 12 weeks of platinum-based therapy. A total of 276 participants will be enrolled in the study and randomized in a 1:1 ratio to maintenance therapy with either selinexor or placebo.

Niraparib Versus Niraparib-bevacizumab Combination in Women With Platinum-sensitive Epithelial Ovarian Cancer

Part 1 (Phase 1): safety and tolerability of bevacizumab-Niraparib combination Part 2 (Randomized Phase 2): to compare Progression-Free Survival (PFS) PARP inhibitors are active as monotherapy to treat patients with recurrent ovarian cancer; the strongest activity being observed in the platinum sensitive, gBRCAmut subgroup as well as in gBRCAwt, HRD population but also in HRD negative disease. In the same population there is level one evidence that bevacizumab is beneficial. And a phase two randomized study has indicated that combination of a PARP inhibitor with anti-angiogenic drug is superior to PARP inhibitor alone. The question is: Is niraparib combined with bevacizumab superior to niraparib? The comparison of tolerability and efficacy of niraparib-bevacizumab combination against niraparib.

A Study of MEK162 vs. Physician's Choice Chemotherapy in Patients With Low-grade Serous Ovarian, Fallopian Tube or Peritoneal Cancer

The MILO Study (MEK Inhibitor in Low-grade Serous Ovarian Cancer) is a Phase 3 study during which patients with recurrent or persistent low-grade serous (LGS) carcinomas of the ovary, fallopian tube or primary peritoneum will receive either investigational study drug MEK162 or a chemotherapy chosen by the physician (liposomal doxorubicin, paclitaxel or topotecan). Patients will be followed to compare the effectiveness of the study drug to that of the selected chemotherapies. Patients may be eligible to crossover from physician's choice chemotherapy to MEK162 if they meet certain inclusion criteria including centrally confirmed disease progression. Approximately 360 patients from North America, Europe and Australia will be enrolled in this study.
