Veliparib concomitant with first-line chemotherapy and as maintenance therapy in ovarian cancer: Final overall survival and disease-related symptoms results.

Introduction: In the VELIA trial, the addition of veliparib to standard first-line platinum-based chemotherapy and continued as maintenance resulted in significantly longer median progression-free survival (PFS) compared with carboplatin plus paclitaxel induction therapy alone (23.5 vs 17.3 months; p < 0.

Association of endometrial cancer epigenetic mismatch repair deficiency with clinicopathologic factors and survival in a large, diverse community-based cohort.

Objectives: To evaluate associations between epigenetic mismatch repair deficiency (MMRd), clinicopathologic factors and overall survival in a diverse endometrial cancer cohort.

Methods: Retrospective analysis of patients with endometrioid cancer whose tumor mismatch repair status was classified by a universal screening program. Associations between epigenetic MMRd, race, other patient characteristics, tumor grade, and stage were assessed using multivariate regression.

Reduced dosing of lenvatinib with pembrolizumab for advanced endometrial cancer.

Objective: Evaluate safety and effectiveness of reduced lenvatinib doses with pembrolizumab in patients with mismatch repair-proficient (MMRp) advanced endometrial cancer.

Methods: In this retrospective cohort study of lenvatinib-pembrolizumab combination therapy, patients were grouped based on initial lenvatinib dose: 20 mg daily (Group 1), less than 20 mg daily (Group 2), and 20 mg daily five days per week (Group 3). The primary outcome was six-month progression-free survival (PFS-6); safety outcomes included incidences of lenvatinib dose discontinuation or reduction due to adverse events (AEs).

Perspectives on inclusion, diversity, equity, and access in clinical trials: findings from a 6-continent survey.

Objective: Clinical trials require the inclusion of all relevant demographic groups, including under-represented populations, to ensure accurate and representative findings. The aim of the study was to assess the status quo of inclusion, diversity, equity, and access in clinical trials across various countries.

Methods: An 18-item online survey was developed and administered to 5 people.

How to optimize and evaluate diversity in gynecologic cancer clinical trials: statements from the GCIG Barcelona Meeting.

Findings from clinical trials have led to advancement of care for patients with gynecologic malignancies. However, restrictive inclusion of patients into trials has been widely criticized for inadequate representation of the real-world population. Ideally, patients enrolled in clinical trials should represent a broader population to enhance external validity and facilitate translation of outcomes across all relevant groups.

Cediranib and Olaparib Combination Compared With Cediranib or Olaparib Alone, or Chemotherapy in Platinum-Resistant or Primary Platinum-Refractory Ovarian Cancer: NRG-GY005.

Purpose: We assessed the efficacy of cediranib, olaparib, and cediranib/olaparib compared with standard-of-care chemotherapy (SOC) in platinum-resistant or platinum-refractory epithelial ovarian cancer (PROC).

Identification of Patients With Ovarian Cancer Experiencing the Highest Benefit From Bevacizumab in the First-Line Setting on the Basis of Their Tumor-Intrinsic Chemosensitivity (KELIM): The GOG-0218 Validation Study.

Purpose: In patients with high-grade ovarian cancer, predictors of bevacizumab efficacy in first-line setting are needed. In the ICON-7 trial, a poor tumor intrinsic chemosensitivity (defined by unfavorable modeled cancer antigen-125 [CA-125] ELIMination rate constant K [KELIM] score) was a predictive biomarker. Only the patients with high-risk disease (suboptimally resected stage III, or stage IV) exhibiting unfavorable KELIM score < 1.

Clinical research in ovarian cancer: consensus recommendations from the Gynecologic Cancer InterGroup.

The Gynecologic Cancer InterGroup (GCIG) sixth Ovarian Cancer Conference on Clinical Research was held virtually in October, 2021, following published consensus guidelines. The goal of the consensus meeting was to achieve harmonisation on the design elements of upcoming trials in ovarian cancer, to select important questions for future study, and to identify unmet needs. All 33 GCIG member groups participated in the development, refinement, and adoption of 20 statements within four topic groups on clinical research in ovarian cancer including first line treatment, recurrent disease, disease subgroups, and future trials.

CA-125 KELIM as a Potential Complementary Tool for Predicting Veliparib Benefit: An Exploratory Analysis From the VELIA/GOG-3005 Study.

Purpose: In VELIA trial, veliparib combined with carboplatin-paclitaxel, followed by maintenance (veliparib-throughout) was associated with improved progression-free survival (PFS) compared with carboplatin-paclitaxel alone in patients with high-grade ovarian carcinomas. We explored the prognostic value of the modeled cancer antigen (CA)-125 elimination rate constant K (KELIM), which is known to be an indicator of the intrinsic tumor chemosensitivity (the faster the rate of CA-125 decline, the higher the KELIM and the higher the chemosensitivity), and its association with benefit from veliparib.

Patients And Methods: Individual KELIM values were estimated from longitudinal CA-125 kinetics.

Olaparib With or Without Cediranib Versus Platinum-Based Chemotherapy in Recurrent Platinum-Sensitive Ovarian Cancer (NRG-GY004): A Randomized, Open-Label, Phase III Trial.

Purpose: Platinum-based chemotherapy is the standard of care for platinum-sensitive ovarian cancer, but complications from repeated platinum therapy occur. We assessed the activity of two all-oral nonplatinum alternatives, olaparib or olaparib/cediranib, versus platinum-based chemotherapy.

Patients And Methods: NRG-GY004 is an open-label, randomized, phase III trial conducted in the United States and Canada.

Second-line olaparib maintenance therapy is associated with poor response to subsequent chemotherapy in BRCA1/2-mutated epithelial ovarian cancer: A multicentre retrospective study.

Introduction: With expanded use of poly (adenosine diphosphate-ribose) polymerase inhibitors (PARPi), there is a potential impact of PARPi resistance on platinum resistance. A post-hoc analysis of SOLO2 demonstrated a reduction in response to subsequent platinum-based therapy among patients who received prior olaparib but not placebo. The present multicentre, retrospective, observational study was conducted to determine the effects of olaparib on subsequent therapy for recurrent epithelial ovarian cancer (EOC).

Impact of veliparib, paclitaxel dosing regimen, and germline BRCA status on the primary treatment of serous ovarian cancer - an ancillary data analysis of the VELIA trial.

Objective: In the Phase 3 VELIA trial (NCT02470585), veliparib added to carboplatin plus paclitaxel concomitantly and as maintenance for women with newly-diagnosed advanced ovarian cancer significantly improved progression-free survival (PFS) versus chemotherapy alone. Here we present exploratory analyses by paclitaxel dosing schedule and germline BRCA (gBRCA) status.

Methods: Women with untreated ovarian carcinoma were randomized (1:1:1) to: veliparib during chemotherapy and maintenance (veliparib-throughout), veliparib during chemotherapy followed by placebo maintenance (veliparib-combination only), or placebo during chemotherapy and maintenance (control).

Impact of homologous recombination status and responses with veliparib combined with first-line chemotherapy in ovarian cancer in the Phase 3 VELIA/GOG-3005 study.

Objective: In the Phase 3 VELIA trial (NCT02470585), PARP inhibitor (PARPi) veliparib was combined with first-line chemotherapy and continued as maintenance for patients with ovarian carcinoma enrolled regardless of chemotherapy response or biomarker status. Here, we report exploratory analyses of the impact of homologous recombination deficient (HRD) or proficient (HRP) status on progression-free survival (PFS) and objective response rates during chemotherapy.

Methods: Women with Stage III-IV ovarian carcinoma were randomized to veliparib-throughout, veliparib-combination-only, or placebo.

Phase 1b study of AVB-500 in combination with paclitaxel or pegylated liposomal doxorubicin platinum-resistant recurrent ovarian cancer.

Objective: GAS6 and AXL are expressed in high-grade serous ovarian cancer but not in normal ovarian tissue. AVB-500, a novel high affinity Fc-sAXL fusion protein, binds GAS6 preventing AXL signaling. This Phase 1b study (NCT03639246) evaluated safety, efficacy, and exploratory predictive markers of AVB-500 combined with paclitaxel (PAC) or pegylated liposomal doxorubicin (PLD) in patients with platinum-resistant ovarian cancer (PROC), and used a model informed drug development (MIDD) approach for identification of the recommended phase 2 dose (RP2D).

Progression-free survival by investigator versus blinded independent central review in newly diagnosed patients with high-grade serous ovarian cancer: Analysis of the VELIA/GOG-3005 trial.

Objective: In the phase 3 VELIA/GOG-3005 trial, veliparib added to carboplatin-paclitaxel and continued as maintenance improved progression-free survival (PFS) compared to carboplatin-paclitaxel alone in patients with newly diagnosed ovarian carcinoma. Primary analysis of PFS was by investigator (INV) assessment, with a supplemental analysis of PFS by blinded independent central review (BICR).

Methods: Patients received veliparib or placebo with carboplatin-paclitaxel (6 cycles) and as maintenance (30 additional cycles).
