AbstractPurpose: To determine the dose limiting toxicities (DLT), maximum tolerated dose (MTD), and recommended phase II dose (RP2D) of veliparib in combination with weekly topotecan in patients with solid tumors. Correlative studies were included to assess the impact of topotecan and veliparib on poly(ADP-ribose) levels in peripheral blood mononuclear cells, serum pharmacokinetics of both agents, and potential association of germline repair gene mutations with outcome. Experimental Design: Eligible patients had metastatic nonhematologic malignancies with measurable disease. Using a 3 + 3 design, patients were treated with veliparib orally twice daily on days 1–3, 8–10, and 15–17 and topotecan intravenously on days 2, 9, and 16 every 28 days. Tumor responses were assessed by RECIST. Results: Of 58 patients enrolled, 51 were evaluable for the primary endpoint. The MTD and RP2D was veliparib 300 mg twice daily on days 1–3, 8–10, and 15–17 along with topotecan 3 mg/m2 on days 2, 9, and 16 of a 28-day cycle. DLTs were grade 4 neutropenia lasting >5 days. The median number of cycles was 2 (1–26). The objective response rate was 10%, with 1 complete and 4 partial responses. Twenty-two patients (42%) had stable disease ranging from 4 to 26 cycles. Patients with germline BRCA1, BRCA2, or RAD51D mutations remained on study longer than those without homologous recombination repair (HRR) gene mutations (median 4 vs. 2 cycles). Conclusions: Weekly topotecan in combination with veliparib has a manageable safety profile and appears to warrant further investigation.

Background: Based primarily on studies concerning early-stage tumours (treated surgically), and locally advanced disease (treated with chemoradiation), the prognosis for women with adenocarcinoma (AC) or adenosquamous (AS) carcinoma has been reported to be poorer than those with squamous cell carcinoma (SCCA) of the cervix. It is unclear whether differences in prognosis also persist in the setting of recurrent or metastatic disease treated using chemotherapy doublets with or without bevacizumab. Methods: Cases were pooled from three Gynaecologic Oncology Group randomised phase III trials of chemotherapy doublets. Pearson's test was used to evaluate response rate (RR) of AC/AS vs SCCA, Kaplan-Meier method to estimate progression-free survival (PFS) and overall survival (OS), and Cox proportional hazards model to estimate the impact of histology on PFS and OS. Results: Of 781 evaluable patients, 77% (N = 599) had SCCA and 23% (N = 182) AC/AS. There were no significant differences in RRs between histologic subgroups. The adjusted hazard ratio (HR) for death for SCCA vs AC/AS was 1.13 (95% CI 0.93, 1.38 P = 0.23). When comparing SC/AS (N = 661, 85%) to AC alone (N = 120, 15%), the adjusted HR for death was 1.23 (95% CI 0.97, 1.57, P = 0.09). Conclusions: AC/AS and SCCA have similar survival in recurrent or metastatic cervical carcinoma when treated with chemotherapy doublets.

AbstractPurpose: In the randomized phase III trial, Gynecologic Oncology Group (GOG) protocol 240, the incorporation of bevacizumab with chemotherapy significantly increased overall survival (OS) in women with advanced cervical cancer. A major objective of GOG-240 was to prospectively analyze previously identified pooled clinical prognostic factors known as the Moore criteria.Experimental Design: Potential negative factors included black race, performance status 1, pelvic disease, prior cisplatin, and progression-free interval <365 days. Risk categories included low-risk (0–1 factor), mid-risk (2–3 factors), and high-risk (4–5 factors). Each test of association was conducted at the 5% level of significance. Logistic regression and survival analysis was used to determine whether factors were prognostic or could be used to guide therapy.Results: For the entire population (n = 452), high-risk patients had significantly worse OS (P < 0.0001). The HRs of death for treating with topotecan in low-risk, mid-risk, and high-risk subsets are 1.18 [95% confidence interval (CI), 0.63–2.24], 1.11 (95% CI, 0.82–1.5), and 0.84 (95% CI, 0.50–1.42), respectively. The HRs of death for treating with bevacizumab in low-risk, mid-risk, and high-risk subsets are 0.96 (95% CI, 0.51–1.83; P = 0.9087), 0.673 (95% CI, 0.5–0.91; P = 0.0094), and 0.536 (95% CI, 0.32–0.905; P = 0.0196), respectively.Conclusions: This is the first prospectively validated scoring system in cervical cancer. The Moore criteria have real-world clinical applicability. Toxicity concerns may justify omission of bevacizumab in some low-risk patients where survival benefit is small. The benefit to receiving bevacizumab appears to be greatest in the moderate- and high-risk subgroups (5.8-month increase in median OS). Clin Cancer Res; 21(24); 5480–7. ©2015 AACR.

ObjectiveThis study aimed to describe pretreatment patient characteristics and baseline quality-of-life scores as they relate to the development of grade 3 or 4 toxicity in patients receiving chemotherapy for advanced/recurrent cervical cancer.MethodsThe study sample was drawn from Gynecologic Oncology Group protocols 179 and 204. Grade 3 or 4 toxicities were considered in 4 specified categories as follows: peripheral neuropathy, fatigue, hematological, and gastrointestinal (GI). The data variables explored included age, stage, pretreatment radiation, performance status (PS) at treatment initiation, and baseline Functional Assessment of Cancer Therapy-Cervix (FACT-Cx) score. A logistic regression model was developed with various adverse events as binary (0/1) outcomes.ResultsSix hundred seventy-three patient-reported questionnaires were used in the analyses. At baseline, pain was the most severe patient-reported symptom. Baseline line-item patient concerns did demonstrate specific correlations with the development of individual toxicities. In 401 patients who were enrolled on Gynecologic Oncology Group 204 (fatigue not measured on 179), a worse PS predicted the development of grade 3 or 4 fatigue (odds ratio, 2.78; 95% confidence interval, 1.66–4.68). Exposure to previous radiation, treatment regimen, and a worse FACT-Cx score were associated with the reporting of both grade 3 or 4 leukopenia (P< 0.05) and anemia (P< 0.0005). Performance status and treatment regimen (P< 0.05) were associated with the development of grade 3 or 4 thrombocytopenia. Age and treatment regimen (P< 0.05) were associated with the development of grade 3 or 4 neutropenia. The FACT-Cx score (P= 0.0016) predicted grade 3 or 4 GI toxicity.ConclusionsThe development of fatigue, hematological, and GI toxicity might be predictable based on factors other than treatment assignment such as age, PS, and patient-reported quality-of-life measurement.

Background GOG 240 was a practice-changing randomised phase 3 trial that concluded that chemotherapy plus bevacizumab for advanced cervical cancer significantly improves overall and progression-free survival, and the proportion of patients achieving an overall objective response, compared with chemotherapy alone. In this study, we aimed to analyse patient-reported outcomes in GOG 240.Methods Eligible adult participants (aged >= 18 years) had primary stage IVB or recurrent or persistent carcinoma of the cervix with measurable disease and GOG performance status of 0-1. Participants were randomly assigned by web-based permuted block randomisation (block size 4) in a 1: 1: 1: 1 ratio to the four treatment groups: cisplatin (50 mg/m(2) intravenously on day 1 or 2 of the treatment cycle) and paclitaxel (135 mg/m(2) intravenously over 24 h or 175 mg/m(2) intravenously over 3 h on day 1), with or without bevacizumab (15 mg/kg intravenously on day 1 or 2), or paclitaxel (175 mg/m(2) over 3 h on day 1) and topotecan (0.75 mg/m(2) for 30 min on days 1-3) with or without bevacizumab (15 mg/kg intravenously on day 1). Treatment assignment was concealed at randomisation (everyone was masked to treatment assignment, achieved by the use of a computer encrypted numbering system at the National Cancer Institute) and became open-label when each patient was registered to the trial. Treatment cycles were repeated every 21 days until disease progression or unacceptable toxicity, whichever occurred first. The coprimary endpoints of the trial were overall survival and safety; the primary quality-of-life endpoint was the score on the Functional Assessment of Cancer Therapy-Cervix Trial Outcome Index (FACT-Cx TOI). For our analysis of patient-reported outcomes, participants were assessed before treatment cycles 1, 2, and 5, and at 6 and 9 months after the start of cycle 1, with the FACT-Cx TOI, items from the FACT-GOG-Neurotoxicity subscale, and a worst pain item from the Brief Pain Inventory. All patients who completed baseline quality-of-life assessments and at least one further follow-up assessment were evaluable for quality-of-life outcomes. This study is registered with ClinicalTrials.gov, number NCT00803062.Findings Between April 6, 2009, and Jan 3, 2012, a total of 452 patients were enrolled in the trial, of whom 390 completed baseline quality-of-life assessment and at least one further assessment and were therefore evaluable for quality-of-life outcomes. In these patients, patient-reported outcome completion declined from 426 (94%) of 452 (at baseline) to 193 (63%) of 307 (9 months post-cycle 1), but completion rates did not differ significantly between treatment regimens (p=0.78). The baseline FACT-Cx TOI scores did not differ significantly between patients who received bevacizumab versus those who did not (p=0.27). Compared with patients who received chemotherapy alone, patients who received chemotherapy plus bevacizumab reported FACT-Cx TOI scores that were an average of 1 . 2 points lower (98 .75% CI -4.1 to 1.7; p=0.30).Interpretation Improvements in overall survival and progression-free survival attributed to the incorporation of bevacizumab into the treatment of advanced cervical cancer were not accompanied by any significant deterioration in health-related quality of life. Patients responding to anti-angiogenesis therapy who maintain an acceptable quality of life could be suitable at progression for treatment with other novel therapies that might confer additional benefit.

TPS2618 Background: PARPs are a highly conserved family of enzymes whose predominant function is to preserve genomic integrity following DNA damage. Preclinical studies demonstrated that PARP inhibitors enhance the cytotoxicity of DNA damaging agents. Specifically, PARP inhibition sensitizes tumor cells to topotecan in vitro and in vivo by trapping PARP1 on damaged DNA and preventing repair of topo I-induced DNA damage (Patel et al., J. Biol. Chem. 287:4198, 2012). Veliparib has been combined with daily topotecan but found to be quite myelosuppressive, requiring reduction in doses of both agents (Kummar et al., Cancer Res. 71:5626, 2011). Based on these data, we sought to determine the maximum tolerated dose (MTD) of veliparib in combination with the less myelosuppressive weekly administration of topotecan in patients with solid tumors. Correlative studies were included to assess the impact of topotecan and veliparib on poly(ADP-ribose) levels in peripheral blood mononuclear cells as well as the pharmacokinetics of both agents. Methods: Eligible patients include any histologically confirmed solid tumor malignancy that is metastatic or unresectable with measurable disease (longest diameter > 2 cm with conventional CT) in patients 18 or older who have received < 2 chemotherapy regimens, ECOG PS < 2 and adequate bone marrow, renal and hepatic function. Using a standard 3+3 design, patients have been treated with veliparib PO twice daily on days 1-3, 8-10 and 15-17 and topotecan IV on days 2, 9 and 16 every 28 days. The trial is currently enrolling at veliparib 300 mg PO twice daily and topotecan 3 mg/m2/dose. Once MTD is established, a phase II clinical trial in platinum resistant ovarian, peritoneal and fallopian tube malignancies is planned. Supported in part by UM1 CA186686 and P50 CA136393.

BACKGROUND Vascular endothelial growth factor (VEGF) promotes angiogenesis, a mediator of disease progression in cervical cancer. Bevacizumab, a humanized anti-VEGF monoclonal antibody, has single-agent activity in previously treated, recurrent disease. Most patients in whom recurrent cervical cancer develops have previously received cisplatin with radiation therapy, which reduces the effectiveness of cisplatin at the time of recurrence. We evaluated the effectiveness of bevacizumab and nonplatinum combination chemotherapy in patients with recurrent, persistent, or metastatic cervical cancer. METHODS Using a 2-by-2 factorial design, we randomly assigned 452 patients to chemotherapy with or without bevacizumab at a dose of 15 mg per kilogram of body weight. Chemotherapy consisted of cisplatin at a dose of 50 mg per square meter of body-surface area, plus paclitaxel at a dose of 135 or 175 mg per square meter or topotecan at a dose of 0.75 mg per square meter on days 1 to 3, plus paclitaxel at a dose of 175 mg per square meter on day 1. Cycles were repeated every 21 days until disease progression, the development of unacceptable toxic effects, or a complete response was documented. The primary end point was overall survival; a reduction of 30% in the hazard ratio for death was considered clinically important. RESULTS Groups were well balanced with respect to age, histologic findings, performance status, previous use or nonuse of a radiosensitizing platinum agent, and disease status. Topotecan-paclitaxel was not superior to cisplatin-paclitaxel (hazard ratio for death, 1.20). With the data for the two chemotherapy regimens combined, the addition of bevacizumab to chemotherapy was associated with increased overall survival (17.0 months vs. 13.3 months; hazard ratio for death, 0.71; 98% confidence interval, 0.54 to 0.95; P=0.004 in a one-sided test) and higher response rates (48% vs. 36%, P=0.008). Bevacizumab, as compared with chemotherapy alone, was associated with an increased incidence of hypertension of grade 2 or higher (25% vs. 2%), thromboembolic events of grade 3 or higher (8% vs. 1%), and gastrointestinal fistulas of grade 3 or higher (3% vs. 0%). CONCLUSIONS The addition of bevacizumab to combination chemotherapy in patients with recurrent, persistent, or metastatic cervical cancer was associated with an improvement of 3.7 months in median overall survival.

Edmonston vaccine strains of measles virus (MV) have significant antitumor activity in mouse xenograft models of ovarian cancer. MV engineered to express the sodium iodide symporter gene (MV-NIS) facilitates localization of viral gene expression and offers a tool for tumor radiovirotherapy. Here, we report results from a clinical evaluation of MV-NIS in patients with taxol- and platinum-resistant ovarian cancer. MV-NIS was given intraperitoneally every 4 weeks for up to 6 cycles. Treatment was well tolerated and associated with promising median overall survival in these patients with heavily pretreated ovarian cancer; no dose-limiting toxicity was observed in 16 patients treated at high-dose levels (10(8)-10(9) TCID50), and their median overall survival of 26.5 months compared favorably with other contemporary series. MV receptor CD46 and nectin-4 expression was confirmed by immunohistochemistry in patient tumors. Sodium iodide symporter expression in patient tumors after treatment was confirmed in three patients by (123)I uptake on SPECT/CTs and was associated with long progression-free survival. Immune monitoring posttreatment showed an increase in effector T cells recognizing the tumor antigens IGFBP2 and FRα, indicating that MV-NIS treatment triggered cellular immunity against the patients' tumor and suggesting that an immune mechanism mediating the observed antitumor effect. Our findings support further clinical evaluation of MV-NIS as an effective immunovirotherapy.

Objectives: In GOG 240, the incorporation of bevacizumab significantly increased overall survival (OS). In this study, we also reported that the topotecan–paclitaxel (TP) backbone was found to be neither superior nor inferior to cisplatin–paclitaxel (CP) for efficacy. The National Comprehensive Cancer Network recently listed the cisplatin–paclitaxel–bevacizumab triplet for cervix cancer. A principal objective of GOG 240 was to prospectively validate previously identified pooled clinical prognostic factors (Moore criteria) and use them to study the chemotherapy backbones.

Objectives: Vascular endothelial growth factor (VEGF) has emerged as an important therapeutic target in advanced cervical cancer. GOG 240 met one of its primary endpoints with the regimens administering the anti-VEGF monoclonal antibody bevacizumab (B), which was associated with significantly improved overall survival (OS). A prospective objective of GOG 240 was to study antiangiogenesis therapy in different risk cohorts using validated prognostic markers known as the Moore criteria.

OBJECTIVE:The objective of this study is to assess effects of clinicopathologic risk factors and contemporary therapeutic interventions on high-risk uterine epithelial carcinoma outcomes. METHODS:Patient-, disease-, and treatment-specific variables were annotated. Survival was estimated via the Kaplan-Meier method. Associations were evaluated with Cox proportional hazard regression and summarized using hazard ratios. RESULTS:From 1999 through 2008, therapy with curative intent was initiated for 119 grade 3 endometrioid (G3EC), 211 serous (USC), and 40 clear cell (CCC) carcinomas. Although clinicopathologic risk factors varied among the histologic subtypes, overall survival (OS) did not differ statistically between subtypes (P=.10) or in stage-for-stage comparative analyses (stage I/II, P=.45; stage III, P=.46; stage IV, P=.65). The 5-year cause-specific survival in stage I/II was 84.8%, 89.8%, and 83.9% for G3EC, USC, and CCC, respectively; multivariable modeling identified lymphovascular space involvement (LVSI) as the only independent prognostic factor (P=.02). For stage III, 5-year OS was 49.2% and 40.0% for G3EC and USC, respectively; multivariable modeling identified age (P<.001), LVSI (P<.001), unresectable nodal disease (P=.03), and regional radiotherapy (P=.01) as independent prognostic factors. For stage IV, 5-year OS was 8.7% and 12.1% for G3EC and USC, respectively; multivariable modeling identified LVSI (P=.002), cervical stromal invasion (P=.02), and adjuvant chemotherapy (P=.02) but not residual disease as independent prognostic factors. CONCLUSIONS:When controlled for disease stage, outcomes did not differ among high-risk histologic subtypes. LVSI was a significant adverse prognostic factor within all stages. The lack of improved outcomes with contemporary therapy suggests that more innovative therapeutic approaches should be given higher priority.
