    ABSTRACT: The study objective was to determine the prognostic significance of serum CA-125 levels in patients with grade 1 serous ovarian carcinoma (SOC) enrolled in a Phase III study. An ancillary analysis of a phase III study of women with advanced epithelial ovarian cancer treated with carboplatin/paclitaxel versus triplet or sequential doublet regimens. Grade 1 SOC was used as a surrogate for low-grade serous carcinoma. Among 3686 enrolled patients, 184 (5%) had grade 1 disease and CA-125 levels available. For those with grade 1 SOC, the median patient age was 56.5; 87.3% had Stage III disease. Median follow-up was 102months and there was no difference in pre-chemotherapy CA-125 by treatment arm (p=0.91). Median pretreatment CA-125 for those with grade 1 SOC was lower (119.1) than for patients with grade 2-3 SOC (246.7; p<0.001). In those with grade 1, pretreatment CA-125 was not prognostic of outcome. However, patients with CA-125 levels that normalized after cycles 1, 2 or 3 were 60-64% less likely to experience disease progression as compared to those who never normalized or normalized after 4cycles (p≤0.024). Normalization of CA-125 levels before the second cycle was negatively associated with death, with a HR of 0.45 (p=0.025). Pretreatment CA-125 level was significantly lower in women with grade 1 SOC compared to those with high-grade SOC. While pretreatment CA-125 was not associated with survival, serial CA-125 measurements during chemotherapy treatment were prognostic, with normalization before the second chemotherapy cycle associated with a decreased risk of death.

    ABSTRACT: Clinical trial endpoints have profound effects on late phase clinical trial design, results interpretation, drug development, and regulatory approval of therapeutics. Selection of the optimal clinical trial endpoint is particularly provocative in ovarian cancer where long overall survival (OS) is observed even for those who present with advanced disease stages. The lack of new regulatory approvals and the lack of harmony between regulatory bodies globally for ovarian cancer therapeutics are of concern. The advantages and disadvantages of the numerous endpoints available are herein discussed within the unique context of ovarian cancer where both crossover and post-progression therapies potentially uncouple the surrogacy between progression-free survival (PFS) and OS, the two most widely supported and utilized endpoints. The roles of patient reported outcomes (PRO) and health related quality of life (HRQoL) are discussed, but even these widely supported parameters are affected by the unique characteristics of ovarian cancer where a significant percentage of patients may be asymptomatic. Original data regarding the endpoint preferences of ovarian cancer advocates is presented. Endpoint selection in ovarian cancer clinical trials should reflect the impact on disease burden and unique characteristics of the treatment cohort while reflecting true patient benefit. Both OS and PFS have led to regulatory approvals and are clinically important. However, current regulatory approval guidance by the FDA indicates that surrogates for overall survival, while acceptable, must be clinically meaningful. OS remains the most objective and accepted endpoint because it is least vulnerable to bias; however, the feasibility of OS in ovarian cancer is compromised by the requirement for large trial size, prolonged time-line for final analysis, and potential for unintended loss of treatment effect from active post-progression therapies. A large magnitude of effect in PFS improvement should establish benefit, and further communication with regulatory authorities to clarify acceptable endpoints should be undertaken.

    ABSTRACT: To examine clinicopathologic variables associated with survival among women with low-grade (grade 1) serous ovarian carcinoma enrolled in a phase III study. This was an ancillary data analysis of Gynecologic Oncology Group protocol 182, a phase III study of women with stage III-IV epithelial ovarian carcinoma treated with carboplatin and paclitaxel compared with triplet or sequential doublet regimens. Women with grade 1 serous carcinoma (a surrogate for low-grade serous disease) were included in the analysis. Among the 3,686 enrolled participants, 189 had grade 1 disease. The median age was 56.5 years and 87.3% had stage III disease. The median follow-up time was 47.1 months. Stratification according to residual disease after primary surgery was microscopic residual in 24.9%, 0.1-1.0 cm of residual in 51.3%, and more than 1.0 cm of residual in 23.8%. On multivariate analysis, only residual disease status (P=.006) was significantly associated with survival. Patients with microscopic residual had a significantly longer median progression-free (33.2 months) and overall survival (96.9 months) compared with those with residual 0.1-1.0 cm (14.7 months and 44.5 months, respectively) and more than 1.0 cm of residual disease (14.1 months and 42.0 months, respectively; progression-free and overall survival, P<.001). After adjustment for other variables, patients with low-grade serous carcinoma with measurable residual disease had a similar adjusted hazard ratio for death (2.12; P=.002) as their high-grade serous carcinoma counterparts with measurable disease (2.31; P<.001). Surgical cytoreduction to microscopic residual was associated with improved progression-free and overall survival in women with advanced-stage low-grade serous ovarian carcinoma.,, NCT00011986. : II.

    ABSTRACT: The goal of this report is to review the activity of promising antifolate and folate receptor agents being developed for ovarian cancer including thymidylate synthetase inhibitors, antifolate receptor antibodies, and folate-chemotherapy conjugates. A literature search was performed over the last 5 years using the terms "folate receptor" and "ovarian cancer" and those that specifically addressed the MOA were included. Abstracts presented within the last 3 years were also searched and included in this review where appropriate. Thymidylate synthetase inhibitors are a promising avenue for ovarian cancer treatment. Phase II trials have shown pemetrexed to have activity in patients with platinum resistant ovarian cancer. Several other thymidylate synthetase inhibitors are in the early phase of development including BGC 945 and ZD-9331. Monoclonal antibodies that target the folate receptor have also shown great potential in the development of ovarian cancer therapies. Farletuzumab is one of these antibodies. A recent phase III trial found that farletuzumab in combination with carboplatin and a taxane did not meet the study's primary endpoint of progression-free survival (PFS). The post hoc exploratory analysis showed, however, a trend toward improved PFS in some patient subsets and further analysis is ongoing. The folate receptor is also utilized through folate conjugates. Vintafolide is one such agent which is currently in phase III development. Encouraging data from phase II trials showed an improvement in PFS from 2.7mo to 5mo. Folate can also be conjugated to radioisotopes for both therapeutic and imaging purposes, and early studies have shown correlation with amount of disease to therapy response. Folate targeted agents continue to show promising antitumor activity in ovarian malignancy and initial clinical experience has demonstrated favorable toxicity profiles. Further development and resources targeted towards these therapies appear to be warranted.

    ABSTRACT: The pro-drug capecitabine is approved for treatment of anthracycline- and paclitaxel-resistant metastatic breast cancer. However, toxicity and large interpatient pharmacokinetic variability occur despite body surface area (BSA)-dosing. We hypothesized that a fixed-dose schedule would simplify dosing and provide an effective and safe alternative to BSA-based dosing. We conducted an open label, single-arm, two-stage study of oral capecitabine with fixed starting dose (3,000 mg total daily dose in two divided doses × 14 days q21 days) in patients with metastatic breast cancer. We correlated pharmacodynamic endpoints [e.g., efficacy (response) per RECIST and toxicity], adherence and pharmacokinetics/pharmacogenetics. Sample size of 45 patients was required to detect a 25 % response rate from null response rate of 10 % using a Simon two-stage design. Twenty-six patients were enrolled in the first-stage and 21 were evaluable after a median of four cycles of capecitabine. Two thirds of patients received either the same dose or a dose 500 mg lower than what would have been administered with a commonly used 2,000 mg/m(2) BSA-dosing schedule. Eight patients had stable disease but progressed after a median of seven cycles. Despite a clinical benefit rate of 19 %, no RECIST responses were observed following the first stage and the study was closed. Dose-reductions were required for grade 2 hand-foot syndrome (28 %) and vomiting (5 %). Adherence was similar when using both patient-reported and Medication Event Monitoring System methods. High interpatient variability was observed for capecitabine and metabolite pharmacokinetics, but was not attributed to observed pharmacogenetic or BSA differences. Single agent activity of capecitabine was modest in our patients with estrogen receptor-positive or -negative metastatic breast cancer and comparable to recent studies. BSA was not the main source of pharmacokinetic variability. Fixed-dose capecitabine is feasible, and simplifies dosing.

    ABSTRACT: OBJECTIVES: To determine prognostic factors for survival in ovarian cancer patients treated with intraperitoneal (IP) chemotherapy using ancillary data from cooperative group clinical trials. METHODS: Data were collected from 428 patients with stage III ovarian cancer who underwent optimal surgical cytoreduction (<1 cm) followed by IP paclitaxel/platinum chemotherapy. Primary endpoints were progression free survival (PFS) and overall survival (OS). Potential prognostic variables were included in Cox proportional hazard regression models. Multivariate analysis was conducted to identify independent prognostic factors. RESULTS: Median PFS was 24.9 months (95% CI, 23.0-29.2) and median OS was 61.8 months (95% CI, 55.5-69.8). Predictors for PFS were histology, surgical stage and residual disease. Age, histology, and residual disease were prognostic for OS. There were no differences in the hazard ratio for death or progression between patients with positive, negative, or unknown lymph node status. For patients receiving IP chemotherapy (n=428), 36% of patients had no residual disease with median PFS of 43.2 months (95% CI 32.5-60.4) and median OS of 110 months (95% CI, 60.0-161.3). CONCLUSIONS: Age, histology, and extent of residual disease were predictors of OS in Stage III patients treated with IP chemotherapy following optimal cytoreduction. Patients with no residual disease following primary surgery that are treated with adjuvant platinum based IP chemotherapy have survival measures that exceed any rates previously seen in this population.

    ABSTRACT: OBJECTIVE: Farletuzumab is a humanized monoclonal antibody to folate receptor-α, which is over-expressed in most epithelial ovarian cancers but largely absent on normal tissue. We evaluated clinical activity of farletuzumab, alone and combined with chemotherapy, in women with first-relapse, platinum-sensitive ovarian, fallopian tube and primary peritoneal cancers. METHODS: Fifty-four eligible subjects received open-label farletuzumab weekly, single agent or combined with carboplatin (AUC5-6) and taxane (paclitaxel 175mg/m2 or docetaxel 75mg/m2), every 21days for 6cycles, followed by farletuzumab maintenance until progression. Twenty-eight subjects with asymptomatic CA125 relapse received single-agent farletuzumab and could receive platinum/taxane chemotherapy plus farletuzumab after single-agent progression. Twenty-six subjects with symptomatic relapse entered the combination arm directly; 21 subjects entered after single agent. Primary endpoints included normalized CA125 and Overall Response Rate (ORR). Duration of each subject's second progression-free interval (PFI2) was compared with her own first response interval (PFI1). RESULTS: Farletuzumab was well-tolerated as single agent, without additive toxicity when administered with chemotherapy. Of 47 subjects who received farletuzumab with chemotherapy, 38 (80.9%) normalized CA125. In 9/42 (21%) evaluable subjects, PFI2 was≥PFI1, better than the historical rate (3%). There was a high response rate among subjects with PFI1 <12months (75%), comparable to that in subjects with PFI1 ≥12months (84%). Complete or partial ORR was 75% with combination therapy. CONCLUSION: Based on this study, farletuzumab with carboplatin and taxane may enhance response rate and duration of response in platinum-sensitive ovarian cancer patients with first relapse after remission of 6-18months.

    ABSTRACT: Up to 50 % of women receiving aromatase inhibitor (AI) complain of AI-associated musculoskeletal symptoms (AIMSS) and 15 % discontinue treatment. We conducted a randomized, sham-controlled trial to evaluate whether acupuncture improves AIMSS and to explore potential mechanisms. Postmenopausal women with early stage breast cancer, experiencing AIMSS were randomized to eight weekly real or sham acupuncture sessions. We evaluated changes in the Health Assessment Questionnaire Disability Index (HAQ-DI) and pain visual analog scale (VAS) following the intervention compared to baseline. Serum estradiol, β-endorphin, and proinflammatory cytokine concentrations were measured pre and post-intervention. We enrolled 51 women of whom 47 were evaluable, including 23 randomized to real and 24 to sham acupuncture. Baseline characteristics were balanced between groups with the exception of a higher HAQ-DI score in the real acupuncture group (p = 0.047). We did not observe a statistically significant difference in reduction of HAQ-DI (p = 0.30) or VAS (p = 0.31) between the two groups. Following eight weekly treatments, we observed a statistically significant reduction of IL-17 (p ≤ 0.009) in both groups. No significant modulation was seen in estradiol, β-endorphin, or other proinflammatory cytokine concentrations in either group. We did not observe a significant difference in AIMSS changes between real and sham acupuncture. As sham acupuncture used in this study may not be equivalent to placebo, further studies with a non-acupuncture arm may be required to establish whether acupuncture is beneficial for the treatment of AIMSS.

    ABSTRACT: These NCCN Guidelines Insights focus on the major updates for the 2012 NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Ovarian Cancer by describing how and why the new recommendations were made. The 6 update topics were selected based on recent important updates in the guidelines and on debate among panel members about recent clinical trials, and include: 1) screening, 2) diagnostic tests for assessing pelvic masses, 3) primary treatment using neoadjuvant chemotherapy, 4) primary adjuvant treatment using bevacizumab in combination with chemotherapy, 5) therapy for recurrent disease, and 6) management of drug/hypersensitivity reactions. These NCCN Guidelines Insights also discuss why some recommendations were not made (eg, panel members did not feel the new data warranted changing the guideline). See "Updates" in the NCCN Guidelines for Ovarian Cancer for a complete list of all the recent revisions.

    ABSTRACT: Purpose Given distinct mechanism of actions of enzastaurin and bevacizumab, preclinical studies suggest enhanced antitumor activity in combination. This phase I study assessed the combination’s safety and efficacy. Patients and methods Six advanced cancer patients could be enrolled in each of 11 cohorts. Patients received an enzastaurin loading dose. Oral enzastaurin (500 mg once daily [QD], 250 mg twice daily [BID], 375 mg BID, 500 mg BID, and 750 mg BID) was escalated in each cohort in combination with bevacizumab dosed at 5 mg/kg every 2 weeks, 10 mg/kg every 2 weeks, or 15 mg/kg every 3 weeks until a dose-limiting toxicity (DLT) occurred in 2 of 6 patients in any cohort. Results Sixty-seven patients (31, ovarian cancer [ovcar]) were evaluable for safety and efficacy. Six treatment-related DLTs occurred: grade 3 fatigue (n = 4), grade 4 cerebral hemorrhage, and grade 3 elevated aspartate transaminase. Common drug-related toxicities included change in color of urine and stool, fatigue, pain, diarrhea, and nausea. The maximum tolerated dose of enzastaurin was 750 mg BID in combination with any tested bevacizumab dose/schedule. Overall response rate was 19.4 % (32.3 % ovcar). Median time to progression was 3.7 months (95 % confidence interval [CI], 2.7–5.5), with 8.3 months (95 % CI, 3.7–11.1) in ovcar. Overall, 35.9 % (50.4 % ovcar) of patients remained without disease progression after 6 months. Conclusion The recommended phase II doses of enzastaurin were 500 mg QD up to 500 mg BID with any tested dose/schedule of bevacizumab. This combination demonstrated encouraging clinical activity, particularly in ovcar.

    ABSTRACT: Epithelial ovarian cancer (EOC) is the most lethal of the gynecologic malignancies, largely due to the advanced stage at diagnosis in most patients. Standard treatment for EOC is surgical debulking followed by platinum-based chemotherapy. While the majority of ovarian cancer patients will respond to initial chemotherapy, most will ultimately relapse. The major focus of current clinical trials for treatment of recurrent ovarian cancer is the use of targeted biologic agents. Folate receptor alpha (FRα) is upregulated in majority of EOC and correlated with tumor stage and grade. It is hypothesized that the presence of overexpressed FRα correlates with the propagation rate of the tumors. FRα is largely absent from normal tissue, making it an attractive therapeutic target. Farletuzumab (MORAb-003), a humanized monoclonal antibody against FRα, has shown antitumor activity in preclinical xenograft models. A Phase 1 dose escalation study did not demonstrate dose-limiting toxicities, or severe adverse effects. A phase 2 efficacy and safety study of farletuzumab with carboplatin and taxane in patients with platinum-sensitive EOC in first relapse, have shown an improved response rate and time to progression compared with historical controls. Recently, preliminary safety data from a phase 1 trial reported that the combination of farletuzumab, carboplatin and PLD has an acceptable safety profile in patients with platinum- sensitive EOC following first or second relapse. Two randomized, double-blind, placebo-controlled Phase 3 studies with farletuzumab plus chemotherapy have been done. A trial of: farletuzumab with weekly paclitaxel in platinum-resistant EOC closed in December 2011 with full report pending. A second trial of farletuzumab with carboplatin and taxane in platinum-sensitive EOC in first relapse is slated to complete accrual in early 2012. Results from these trials will help define the role of farletuzumab in EOC.

    ABSTRACT: Activation and dimerization of the ERBB family play a role in the pathogenesis and progression of ovarian cancer. We conducted a phase II trial to evaluate the activity and tolerability of lapatinib in patients with recurrent or persistent epithelial ovarian cancer (EOC) and to explore the clinical value of expression levels of epidermal growth factor receptors (EGFR), phosphorylated EGFR, HER-2/neu, and Ki-67, and the presence of EGFR mutations. Eligible patients had recurrent or persistent EOC or primary peritoneal carcinoma, measurable disease, and up to 2 prior chemotherapy regimens for recurrent disease. Patients were treated with lapatinib 1500 mg/day. The primary endpoint of efficacy was 6-month progression free survival (PFS). Twenty-five of 28 patients were eligible and evaluable for analysis of efficacy and toxicity. Two (8.0%) were alive and progression-free at 6 months. No objective responses were observed. There were 1 grade 4 toxicity (fatigue) and few grade 3 toxicities. Associations between Ki-67 with prior platinum-free interval, PFS, and a polymorphism in EGFR were suggested. Lapatinib has minimal activity in recurrent ovarian cancer. Ki-67 expression may be associated with prior PFS and a polymorphism in EGFR exon 20 (2361G>A, Q787Q).

    ABSTRACT: The majority of breast cancers are diagnosed in postmenopausal women. Competing comorbidities, particularly cardiovascular disease (CVD), should be considered when individualizing adjuvant therapies for these women. We compared the 10-year predicted breast cancer recurrence risk with CVD risk among postmenopausal women with hormone receptor-positive (HR+), non-metastatic breast cancer. CVD risk factor data were prospectively collected from postmenopausal women with stage I-III, HR+ breast cancer initiating adjuvant aromatase inhibitor therapy. We compared predicted 10-year CVD risk, including the composite index heart age, computed from modified Framingham risk score, with predicted 10-year risk of breast cancer recurrence using Adjuvant! Online. We created multivariable logistic regression models to estimate the odds ratios (OR) and 95% confidence intervals (CI) for greater CVD risk than breast cancer recurrence risk. Among 415 women, mean age and heart age were 60 and 67 years, respectively. Overall, 43% of women had a predicted 10-year CVD risk equivalent to breast cancer recurrence risk and 37% had CVD risk higher than breast cancer recurrence risk. Predicted CVD risk was higher than breast cancer recurrence risk for stage I disease (OR: 6.1, 95% CI: 3.4-11.2) or heart age >65 (OR: 12.4, 95% CI: 7.0-22.6). The majority of postmenopausal women with HR+ early breast cancer had a predicted 10-year CVD risk that was equivalent to or higher than breast cancer recurrence risk. Physicians should weigh competing risks and offer early screening and cardiac prevention strategies for women at a greater risk for CVD.

    ABSTRACT: Excision repair cross-complementation group 1 (ERCC1) is required for the repair of platinum-induced DNA damage. This study sought to assess the prognostic value of ERCC1 expression, measured by immunohistochemistry (IHC) using a highly specific antibody, in advanced epithelial ovarian cancer (EOC) patients treated with platinum-based chemotherapy. Formalin-fixed, paraffin-embedded tumors were collected from two GOG phase III trials (GOG-172 and GOG-182) of patients with stage III/IV EOC treated with platinum-based chemotherapy. ERCC1 was detected by (IHC) using FL297 polyclonal antibody and tumors were categorized as negative or positive, based on nuclear staining of tumor cells. ERCC1 genotyping was performed as previously reported. Associations between ERCC1 expression and clinical characteristics, platinum responsiveness, progression-free survival (PFS) or overall survival (OS) were evaluated. Of 408 eligible patients, 27% had tumors that were ERCC1 positive. ERCC1 expression was not associated with clinical characteristics or platinum-responsiveness. Women with ERCC1-positive versus -negative tumors had similar median PFS (17.9 months versus 17.5 months, respectively, p=0.59), median OS (52.0 months versus 47.0 months, respectively, p=0.30), risk of disease progression (adjusted hazard ratio [HR]=0.90, 95% confidence interval (CI): 0.71-1.15, p=0.41), and risk of death (adjusted HR=0.81, 95% CI: 0.61-1.07, p=0.14). ERCC1 expression, as measured by IHC, was not associated with single nucleotide polymorphisms (SNPs), in codon 118 and C8092A, of the ERCC1 gene. ERCC1 expression, measured by IHC in pre-treatment tumor specimens, using a highly specific antibody, has limited clinical value in patients with advanced EOC treated with platinum and taxane based chemotherapy.

    ABSTRACT: The peritoneal cavity is the major site of disease in ovarian cancer. The peritoneal predominance of disease provides a rationale for administration of chemotherapy within the peritoneal cavity. Intraperitoneal (IP) chemotherapy for ovarian cancer has been studied rigorously for more than 30 years and has been reproducibly shown to improve the survival of patients with ovarian cancer. Three large randomized trials of IP compared with intravenous (IV) therapy have demonstrated statistically significant improvement in clinical outcome measures. Despite this, the IP approach has not gained widespread acceptance in the treatment of ovarian cancer. Here, we review reported, recently completed, and ongoing trials of IP therapy in ovarian cancer including attempts to improve the tolerability and acceptance of this proven approach.

    ABSTRACT: To define the maximum tolerated dose (MTD) and assess the feasibility of intravenous (IV) paclitaxel, intraperitoneal (IP) carboplatin, and IP paclitaxel in women with newly diagnosed Stages II-IV ovarian, fallopian tube, or primary peritoneal carcinoma. Patients received escalating doses of paclitaxel IV and carboplatin IP on day 1 and paclitaxel IP 60 mg/m(2) on day 8. A standard 3+3 design was used in the escalation phase. A two-stage group sequential design with 20 patients at the MTD was used in the feasibility phase. Patient-reported neurotoxicity was assessed pre and post treatment. Patients were treated with paclitaxel 175 mg/m(2) IV and carboplatin IP from AUC 5-7 on day 1 and paclitaxel 60 mg/m(2) IP on day 8. The MTD was estimated at carboplatin AUC 6 IP and 25 patients enrolled at this dose level. Within the first 4 cycles, seven (35%) of twenty evaluable patients had dose-limiting toxicities (DLTs) including grade 4 thrombocytopenia (1), grade 3 neutropenic fever (3), >2 week delay due to ANC recovery (1), grade 3 LFT (1), and grade 3 infection (1). De-escalation to paclitaxel 135 mg/m(2) IV was given to improve the safety. After six evaluable patients completed 4 cycles without a DLT, bevacizumab was added and six evaluable patients completed 4 cycles with one DLT (grade 3 hyponatremia). Paclitaxel at 175 mg/m(2) IV, carboplatin AUC 6 IP day 1 and paclitaxel 60 mg/m(2) IP day 8 yield 18-56% patients with DLTs. The tolerability of the regimen in combination with bevacizumab was indicated in a small cohort.
