Abstract
OBJECTIVES The WNT pathway is an important oncologic driver of epithelial ovarian cancer (EOC). The first-in-class recombinant fusion protein ipafricept (IPA) blocks Wnt signaling through binding of Wnt ligands. This phase Ib trial was designed to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RPh2) for IPA in combination with taxane and platinum therapy (C/P). METHODS Dose escalation started with a standard 3 + 3 design for IPA/C/P with q3w intravenous IPA on Day 1, in cycles 1 to 6 with C (AUC = 5 mg/ml·min) and P (175 mg/m2). For enhanced bone safety the trial was revised to 6-patient cohorts with a q3w regimen of IPA on Day 1 and C/P on Day 3 (IPA → C/P). RESULTS 37 patients have been treated; 30 of whom were treated following protocol revision to q3w IPA(D1) → C/P(D3) (2 & 4 mg/kg). IPA-related TEAEs that occurred in ≥15% included: fatigue (40%); nausea (35%); diarrhea and decreased appetite (22%) each; dysgeusia (19%); and vomiting (16.2%). 22% reported ≥1 IPA related TEAE Grade ≥3 the most common of which was neutropenia at 16%. There were no DLTs; the MTD was not reached. The maximum administered dose based on bone safety was 6 mg/kg. The overall response rate (ORR) was 75.7%. Median PFS was 10.3 months (95% CI 8.5-14.2) and OS 33 months (95% CI 23.4-NR). CONCLUSIONS IPA is well tolerated in combination with sequential C/P. ORR, PFS and OS are comparable to historical data but bone toxicity at efficacy doses of this particular Wnt inhibitor limit further development in EOC.

Abstract
OBJECTIVE This phase I study aimed to determine the maximum tolerated dose (MTD) of Genexol-PM, when combined with carboplatin, as a first-line treatment in patients with advanced ovarian cancer. METHODS This open-label, multicenter, phase I, dose-escalation study included 18 patients (median age: 59.0 years, range: 40-75 years) diagnosed with advanced epithelial ovarian cancer. All patients had measurable residual disease after debulking surgery. Patients were assigned to groups (n=6 each group) that received different doses of Genexol-PM (220, 260, and 300 mg/m², once every 3 weeks) and 5 area under the curve (AUC) carboplatin. Safety and efficacy were analyzed for each dose group. RESULTS In this intention-to-treat population, 3 out of 18 patients dropped out of the study: 1 due to dose-limiting toxicity (DLT), 1 due to hypersensitivity, and 1 was lost during follow-up. DLTs were not reported at 220 mg/m² or 260 mg/m², but at 300 mg/m², 1 patient experienced DLT (grade 3 general pain). The MTD of Genexol-PM was not determined, but a dose of 300 mg/m² or less could be recommended for the phase II study. Most patients (73.9%) with adverse events recovered without sequelae, and no death occurred that was related to the disease or treatment. The best overall response rate was 94.1%. CONCLUSION Genexol-PM combined with carboplatin was well tolerated as a first-line treatment, and good responses were observed in patients with advanced ovarian cancer. Based on these results, we recommended a dose of 300 mg/m² or less for a phase II study.

Abstract
OBJECTIVE Farletuzumab is a humanized monoclonal antibody that binds to folate receptor alpha, over-expressed in epithelial ovarian cancer (EOC) but largely absent in normal tissue. Previously, carboplatin plus pegylated liposomal doxorubicin showed superior progression-free survival and an improved therapeutic index compared with carboplatin/paclitaxel in relapsed platinum-sensitive EOC. This study assessed safety of farletuzumab/carboplatin/pegylated liposomal doxorubicin in women with platinum-sensitive recurrent EOC. METHODS This multicenter, single-arm study enrolled patients with platinum-sensitive EOC in first or second relapse for treatment with weekly farletuzumab 2.5mg/kg plus carboplatin AUC5-6 and pegylated liposomal doxorubicin 30mg/m(2) every 4weeks for 6cycles. Subsequently, maintenance with single-agent farletuzumab 2.5mg/kg once weekly or farletuzumab 7.5mg/kg once every three weeks continued until progression. The primary objective was to assess the safety of farletuzumab/carboplatin/pegylated liposomal doxorubicin. RESULTS Fifteen patients received a median of 12.0cycles (range, 3-26) of farletuzumab as combination therapy or maintenance, for a median of 45.0weeks (range 9-95). Farletuzumab/carboplatin/pegylated liposomal doxorubicin was generally well tolerated, with no farletuzumab-related grades 3-4 adverse events. The most commonly reported adverse events were associated with combination chemotherapy: fatigue (73.3%), nausea (46.7%), and neutropenia (40%). Ten patients had grade ≥3 adverse events, most frequently neutropenia and fatigue. No cardiac toxicity was seen. Best overall responses (RECIST) were a complete response for one patient, partial responses for 10 patients, and stable disease for four patients. CONCLUSIONS Farletuzumab plus carboplatin/pegylated liposomal doxorubicin in women with platinum-sensitive EOC demonstrated a safety profile consistent with that of carboplatin plus pegylated liposomal doxorubicin.

Abstract
AIM: The objective of this multicenter phase II study was to evaluate the effects of biweekly paclitaxel and carboplatin combination chemotherapy on response rate and toxicities in patients with epithelial ovarian cancer. PATIENTS AND METHODS Patients with International Federation of Gynecology and Obstetrics stage II to IV ovarian cancer received paclitaxel at a dose of 120 mg/m(2) and carboplatin at an area under the curve of 3 mg/mL per minute every 2 weeks for 8 or more cycles. Inclusion criteria included an Eastern Cooperative Oncology Group performance status of 0 to 2 and no previous chemotherapy. Informed consent was obtained from each patient before the start of treatment. RESULTS From March 2003 through July 2009, 42 patients from 5 institutions were eligible to be evaluated for response and toxicity. The median age was 60.5 years (age range, 34-81 years). The International Federation of Gynecology and Obstetrics stage was stage II in 3 patients, stage III in 31 patients, and stage IV in 8 patients. The response rate was 66.7% (95% confidence interval: 50.5%-80.4%). Sixty-nine percent (29 of 42) of patients received 8 or more cycles of chemotherapy. The median progression-free survival was 18.5 months, and overall survival was 59.1 months. The most common grade 3 or 4 hematological toxicity was neutropenia (61.0%). No patients had grade 3 or 4 thrombocytopenia. The most common grade 3 nonhematological toxicities were neuropathy (4.9%) and nausea (2.4%). CONCLUSION Paclitaxel combined with carboplatin using a biweekly schedule is a safe and effective chemotherapy regimen for patients with epithelial ovarian cancer. Our results suggest that a biweekly schedule is well tolerated and is less toxic than a triweekly schedule.

Abstract
BACKGROUND/PURPOSE This study was designed to evaluate the response and toxicity of sorafenib alone or when combined with carboplatin and paclitaxel in patients with platinum-sensitive, recurrent ovarian cancer, fallopian tube cancer, or primary peritoneal cancer (EOC). METHODS Patients with recurrent platinum-sensitive EOC with no more than 2 prior courses of chemotherapy were randomized to single-agent sorafenib 400 mg twice daily or combination sorafenib 400 mg bid (days 2-19) with IV carboplatin (AUC 6) and IV paclitaxel 175 mg/m(2) (S+C/T) every 3 weeks. Single agent sorafenib could cross over to combination upon progression. RESULTS Patients were initially randomized to either arm, however, due to poor accrual, sorafenib arm was prematurely closed. A total of 13 patients were evaluable for response to sorafenib and 23 patients were evaluable for response to S+C/T. Objective response rate (RR) was 15 % for patients on sorafenib vs. 61 % for patients on S+C/T (p = 0.014); stable disease was seen in 62 % and 35 %, respectively. Clinical benefit rate (CBR) at 4 months (mos.) was 69 % for S and 65 % for S+C/T. The median progression free survival was 5.6 months on sorafenib vs. 16.8 months on S+C/T (p = 0.012) and there was no significant difference of overall survival between two arms (p = 0.974) with median overall survival 25.6 months under sorafenib vs. 25.9 months on S+C/T. Patients remained on trial for a median of 7.8 cycles on sorafenib and 5.4 cycles on S+C/T. CONCLUSION Sorafenib, alone or in combination with carboplatin and paclitaxel, has activity in patients with platinum-sensitive EOC. Sorafenib in combination with carboplatin and paclitaxel improved RR and PFS; however, there were increased grade and frequencies of toxicities.

Gynecologic oncology. 2013;(1):169-73
Abstract
OBJECTIVES The primary objective of this study was to evaluate the safety and tolerability of a formulated IL-12 plasmid administered intraperitoneally (IP) in conjunction with intravenous (IV) carboplatin/docetaxel in platinum-sensitive ovarian cancer patients. METHODS Escalating doses of IL-12 plasmid (phIL-12) formulated with the lipopolymer PEG-PEI-Cholesterol (PPC) were administered IP every 10-11 days for a total of four treatments and the highest dose was expanded to eight treatments. Patients also received IV carboplatin (AUC 5) and docetaxel (75 mg/m(2)) every 21 days. Patients were followed for safety, biological activity and antitumor activity after phIL-12/PPC treatment. RESULTS All 13 patients enrolled in the study received both phIL-12/PPC and chemotherapy treatment. There were 49 plasmid-associated adverse events (AEs). The most common AEs were abdominal pain, transient hypotension, low grade fever, catheter site pain, chills, dysgeusia, infusion-related reaction, and nausea. These AEs appeared to be plasmid dose related. Grade 3 AEs included manageable abdominal pain and cytokine release syndrome. There were no dose limiting toxicities and the plasmid treatment did not augment the chemotherapy-associated AEs. The best overall antitumor response (17% CR, 33% PR, 42% SD and 8% PD) was typical of the patient population enrolled for the study. Translational studies showed rise in IFN-γ and TNF-α concentrations in a dose dependent manner. CONCLUSIONS The escalating doses and cycles of intraperitoneal phIL-12/PPC when combined with carboplatin/docetaxel chemotherapy in recurrent ovarian cancer patients were well tolerated and did not appear to exacerbate the side effects or attenuate the efficacy of the chemotherapy treatment.

Abstract
OBJECTIVE This trial determined the efficacy and tolerability of sorafenib and weekly topotecan in patients with platinum-resistant ovarian cancer (OC) or primary peritoneal carcinomatosis (PPC). METHODS Primary endpoints were maximum tolerated dose of sorafenib with weekly topotecan (phase I) and response rate (phase II). Secondary endpoints were progression free survival (PFS), overall survival (OS), toxicity, and rate of clinical benefit. Eligibility included recurrent platinum-resistant OC or PPC, <3 prior regimens, normal end-organ function. 3+3 dose escalation was used for phase I, sorafenib being tested at 400mg and 800 mg orally daily. Topotecan dose was reduced from 4 mg/m(2) to 3.5mg/m(2) IV weekly. The phase II regimen was sorafenib 400mg daily and topotecan 3.5mg/m(2) weekly on days 1, 8, 15 of a 28 days cycle. RESULTS 16 patients were enrolled in phase I and 14 patients in phase II. Median age was 52.5 years (range 35-79), 27 patients had OC, and 3 PPC. Median number of cycles administered was 2.5 (0-15). There were 5 partial responses (PR) (16.7%), and 14 patients (46.7%) with stable disease (SD). Four PRs were recorded during phase I and 1 during phase II. One of those PRs occurred in a patient with platinum-sensitive disease. Grade 3/4 toxicities included leukopenia/neutropenia (23%), thrombocytopenia (17%), anemia (10%), fatigue, nausea, vomiting (7% each). One case of grade 3 hand-foot syndrome was recorded. CONCLUSIONS The combination of sorafenib and topotecan causes significant toxicity, precluding administration of full doses and resulting in modest clinical efficacy in platinum resistant OC or PPC.

Abstract
PURPOSE Sorafenib is a kinase inhibitor targeting Raf and other kinases (ie, vascular endothelial growth factor receptor [VEGFR], platelet-derived growth factor receptor [PDGFR], Flt3, and c-KIT). This study assessed its activity and tolerability in patients with recurrent ovarian cancer (OC) or primary peritoneal carcinomatosis (PPC). METHODS This open-label, multi-institutional, phase II study used a two-stage design. Eligible patients had persistent or recurrent OC/PPC after one to two prior cytotoxic regimens, and they experienced progression within 12 months of platinum-based therapy. Treatment consisted of sorafenib 400 mg orally twice per day. Primary end points were progression-free survival (PFS) at 6 months and toxicity by National Cancer Institute criteria. Secondary end points were tumor response and duration of PFS and overall survival. Biomarker analyses included measurement of ERK and b-Raf expression in tumors and phosphorylation of ERK (pERK) in peripheral-blood lymphocytes (PBLs) before and after 1 month of treatment. Results Seventy-three patients were enrolled, of which 71 were eligible. Fifty-nine eligible patients (83%) had measurable disease, and 12 (17%) had detectable disease. Significant grade 3 or 4 toxicities included the following: rash (n = 7), hand-foot syndrome (n = 9), metabolic (n = 10), GI (n = 3), cardiovascular (n = 2), and pulmonary (n = 2). Only patients with measurable disease were used to assess efficacy. Fourteen survived progression free for at least 6 months (24%; 90% CI, 15% to 35%). Two patients had partial responses (3.4%; 90% CI, 1% to 10%); 20 had stable disease; 30 had progressive disease; and seven could not have their tumor assessed. ERK and b-Raf were expressed in all tumors. Exploratory analyses indicated that pERK in post-treatment PBL specimens was associated with PFS. CONCLUSION Sorafenib has modest antitumor activity in patients with recurrent OC, but the activity was at the expense of substantial toxicity.

Abstract
BACKGROUND Nab-paclitaxel is a novel Cremophor®-free nanoparticle of albumin-stabilized paclitaxel, which has favorable efficacy and toxicity characteristics relative to other solvent-based taxanes, such as paclitaxel and docetaxel. METHODS Eligible patients had platinum- and taxane-resistant ovarian cancer, defined by persistent or progressive disease following primary chemotherapy (n = 5) or recurrence within 6 months of treatment completion (n = 42). All patients had measurable disease, no prior therapy for recurrent disease and Gynecologic Oncology Group performance status of ≤ 2. Treatment was nab-paclitaxel, 100 mg/m² days 1, 8, and 15 on a 28-day schedule. The primary endpoint was Response Evaluation Criteria in Solid Tumors v1.0 response rate, evaluated in a 2-stage design (with power of 0.90 for a RR of 25% and with alpha of 0.05 for RR of 10%). RESULTS Fifty-one patients were enrolled of which 47 were evaluable; median time from frontline therapy completion to registration was 21 days. Patient demographics include median age: 59 (34-78) years, serous histology: 72%, and high-grade: 81%. EFFICACY one complete and 10 partial responses were confirmed (23%); 17 patients (36%) had stable disease. The median progression-free survival was 4.5 months (95% CI: 2.2-6.7); overall survival was 17.4 months (95% CI: 13.2-20.8). Seventeen patients (36%) had PFS > 6 months. TOXICITY there were no grade 4 events; grade 3 events were neutropenia (6), anemia (3), GI (2), metabolic (2), pain (2), and leukopenia (1); neurosensory toxicity was observed as grade 2:5, grade 3:1. CONCLUSIONS Nab-paclitaxel has noteworthy single-agent activity and is tolerable in this cohort of refractory ovarian cancer patients previously treated with paclitaxel.

Abstract
INTRODUCTION Ecological and experimental studies suggest that vitamin D may be associated with a reduced risk of ovarian cancer. In this study, we sought to determine the risk of developing ovarian cancer according to serum 25-hydroxyvitamin D (25-OHD) concentrations assessed on average 5 years before the diagnosis. METHODS We conducted a population-based longitudinal case-control study nested within the Finnish Maternity Cohort (FMC) which contains serum samples of virtually all pregnant women in Finland since 1983. Among them, 201 ovarian cancers diagnosed within 10 years of serum sampling were randomly selected as cases for this study. For each case, we selected two controls matched for age, parity and sampling season (+/-4 weeks) and one control matched for age and parity but for the opposite sampling season (6 months+/-4 weeks). RESULTS The relative risks (estimated as odds ratio, OR) for ovarian cancer comparing the lowest quintile to the highest quintile of serum 25-OHD concentration were 1.8 (95% CI 0.9-3.5) among controls matched for the same season, and 1.1 (95% CI 0.6-2.2) among controls matched for the opposite season. The OR among women with insufficient (<75 nmol/L) serum 25-OHD concentration was 2.7 (95% CI 1.0-7.9, lower limit, 0.95) compared to that among those with sufficient (75 nmol/L) serum 25-OHD concentration. No differences in the point estimates were observed between serous or mucinous histological subtypes of ovarian cancer. CONCLUSION Overall, we did not observe a significant association between serum 25-OHD concentrations and the risk of ovarian cancer. However, we found evidence suggestive of an increased risk among women with low to insufficient serum 25-OHD concentrations.
