90 Background: ABI-007 is a novel Cremophor-free nanoparticle albumin-bound paclitaxel. Cremophor-free formulation allows administration using a shorter infusion schedule (30 minutes) and without the need for premedicaion to prevent solvent-based hypersensitivity reactions.This single arm phase II study evaluated the efficacy and safety of ABI-007 given every three weeks to unresectable or recurrent gastric cancer patients (pts) who had received one prior chemotherapy regimen containing fluoropyrimidine and developed disease progression (PD) or recurrence. Methods: Eligibility include: histologically or cytologically confirmed gastric adenocarcinoma , received one prior regimen containing fluoropyrimidine analogs and developed PD or recurrence, age: 20 - 74, at least one measurable lesion by RECIST(1.0), PS:0-2, adequate organ function and written informed consent. Study duration was until PD or unacceptable toxicity developed. Pts received ABI-007 260 mg/m2, i.v. on day 1 of each 21 day cycle) without premedication. The primary endpoint was overall objective response rate (ORR). Results: From April 2008 to July 2010, total of 56 pts were enrolled, 55 received the study treatment, and 54 pts were evaluable for response. Median age was 64, Male/Female was 43/12, PS:0/1/2 was 33/22/0 and number of sites of metastasis corresponding was 1/2/≥3:19/21/15. ORR was 27.8% (15/54; 95%CI, 16.5-41.6) and DCR (disease control rate:CR+PR+SD) was 59.3% (32/54, 95%CI, 45.0-72.4) for all evaluable patients. One confirmed CR was observed. Median progression–free survival was 2.9 months (95%CI, 2.4-3.6), and median overall survival was 9.0 months (95%CI, 6.6-11.5). The most common grade 3/4 toxicities were neutropenia (49.1%), leucopenia (20.0%), lymphopenia (10.9%); and peripheral sensory neuropathy (23.6%). Conclusions: These data demonstrate that ABI-007 showed promising activity with well-tolerated toxicities for previously treated unresectable or recurrent gastric cancer pts.

168 Background: Nanoparticle albumin-bound paclitaxel (nab-PTX) is a novel, solvent polyoxyethylated castor oil-free, biologically interactive form of paclitaxel (PTX). Nab-PTX allows shorter infusion schedules and needs no premedication for hypersensitivity reactions, so nab-PTX will be used as the alternative to PTX for more patients. In Japan, nab-PTX was approved as tri-weekly regimen (210mg/m2 every 3weeks) for gastric cancer. On the other hands, weekly PTX (80mg/m2 on day1, 8, and 15, every 4weeks) is mostly used as PTX regimen as 2nd or later line treatment for gastric cancer in Japan. So in practice, nab-PTX would be used by weekly regimen same as weekly PTX. However, the safety and efficacy of weekly nab-PTX for gastric cancer had not been reported yet. Methods: Unresectable or metastatic gastric cancer patients who began receiving weekly nab-PTX as 2nd or later line chemotherapy in our two facilities from February 2013 to August 2014 were retrospectively analyzed for the safety and efficacy. Written informed consent about the treatment of weekly nab-PTX was obtained from all patients before treatment. Results: A total of 32 patients were assessed, retrospectively. The dose and schedule of nab-PTX was 100mg/m2 on day1, 8, and 15, every 4weeks in all patients. Patients characteristics were as follows: median age 67.5(37-84); Male/female: 24/8; PS 0/1/2/3:15/8/7/2; treatment line 2/3/4/5: 12/14/5/1. The overall response rate was 9.3% (CR/PR/SD/PD/NE: 1/2/12/15/2). The median progression-free survival (mPFS) and median overall survival (mOS) were 2.99 months and 5.95 months, in all patients. In 23 patients whose PS were 0 or 1, mPFS and mOS were 4.14 months and 8.44 months. Most common grade 3/4 hematological toxicities were anemia (46.9%), neutropenia (40.6%), febrile neutropenia (15.6%). About the sensory neuropathy, grade 3 was 9.3%, grade2 was 21.9%, and grade1 was 3.1%. There were no treatment-related deaths. Conclusions: Weekly nab-PTX showed promising efficacy against previously treated unresectable or recurrent gastric cancer especially for good PS patients, The Common toxicities of weekly nab-PTX were well-tolerated.

PurposeTo evaluate the efficacy and safety of ixabepilone in patients with metastatic breast cancer (MBC) resistant to anthracycline, taxane, and capecitabine, in this multicenter, phase II study.Patients and MethodsPatients with measurable disease who had tumor progression while receiving prior anthracycline, taxane, and capecitabine were enrolled. Ixabepilone 40 mg/m2monotherapy was administered as a 3-hour intravenous infusion on day 1 of a 21-day cycle. The primary end point was objective response rate (ORR), assessed by an independent radiology facility (IRF).ResultsA total of 126 patients were treated and 113 were assessable for response. Patients were heavily pretreated: 88% had received at least two lines of prior chemotherapy in the metastatic setting. IRF-assessed ORR was 11.5% (95% CI, 6.3% to 18.9%) for response-assessable patients. Investigator-assessed ORR for all treated patients was 18.3% (95% CI, 11.9% to 26.1%). Fifty percent of patients achieved stable disease (SD); 14.3% achieved SD ≥ 6 months. Median duration of response and progression-free survival were 5.7 and 3.1 months, respectively. Median overall survival was 8.6 months. Patients received a median of 4.0 treatment cycles (range, one to 16 cycles), and 25% of patients received ≥ eight cycles. Grade 3/4 treatment-related events included peripheral sensory neuropathy (14%), fatigue/asthenia (13%), myalgia (8%), and stomatitis/mucositis (6%). Resolution of grade 3/4 peripheral sensory neuropathy occurred after a median period of 5.4 weeks.ConclusionIxabepilone demonstrated clear activity and a manageable safety profile in patients with MBC resistant to anthracycline, taxane, and capecitabine. Responses were durable and notable in patients who had not previously responded to multiple prior therapies.

5576 Background: Endometrial cancer (EC) is the most common gynecologic malignancy. Vascular endothelial growth factor (VEGF) overexpression in EC correlates with poor outcome, thus targeting VEGF is a rational therapeutic approach. We have conducted a two-stage open-label phase II study in advanced EC with sunitinib, an oral tyrosine kinase inhibitor of multiple VEGF receptors. Methods: Eligible pts have recurrent or metastatic EC and have received up to 1 prior chemotherapy (CT) regimen for metastatic disease. Sunitinib is given at 50 mg daily (OD) for 4 consecutive weeks (wks) followed by 2 wks off. Dose could be reduced to 37.5 mg OD and then 25 mg OD in the setting of toxicity. Imaging is repeated every 12 wks. Primary objectives are objective response rate (ORR by RECIST) and rate of 6-month progression-free survival (PFS). If 1 or more responses occur in the first 15 evaluable pts, the study would continue to a second stage (total = 30 pts). Secondary objectives are time to progression (TTP), overall survival (OS), and safety. Results: We report the results of the first stage of this study. Sixteen pts have been treated (median age: 63; range 41–74) with 37 cycles of sunitinib (median 2; range: 1–7). Baseline ECOG PS was 0 (7 pts), 1 (8 pts), or 2 (1 pt). Histology was endometrioid (7 pts), serous (5 pts), clear cell (1 pt), or mixed/other (3 pts). Most pts had high-grade histology (G3: 8; G2: 4; G1: 2; GX: 2). Nine pts had prior adjuvant CT, 8 pts had 1 prior CT for advanced EC, 4 pts had prior hormones and 7 pts had prior radiotherapy. Partial response was achieved by 2 pts (ORR = 12.5%), and 2 other pts had a best response of stable disease; 3 of these pts remained progression-free > 6 months. Median TTP = 2.5 months (95% CI: 2.47-NR), and median OS = 6.2 months (95% CI: 5.1-NR). Grade 3/4 adverse events (AE) in >10% of pts were fatigue (7 pts, 44%) and hypertension (5 pts, 31%). Dose reduction was required for 11 of 16 pts (69%). Two pts were inevaluable after receiving <2 cycles due to AE (grade 4 hyponatremia; grade 3 fatigue) and 1 other pt has yet to complete 2 cycles. Conclusions: Sunitinib shows preliminary activity in EC. This trial will proceed to a second stage of accrual to further explore the efficacy and safety of sunitinib in advanced EC.

9517 Background: Temozolomide and topotecan have shown activity in several pediatric cancers, including neuroblastoma. Resistance to alkylating agents due to MGMT expression, MMR deficiency or microsatellite instability may be overcome through the combination with topoisomerase I inhibitors. The combination of temozolomide and topotecan (TOTEM) was well tolerated and showed preliminary activity in children with neuroblastoma and glioma (Rubie et al, 2010). Methods: This multicenter, non-randomized, multi-cohort Phase II study included children with neuroblastoma according to a 2-stage Simon design, and patients with central nervous system (CNS) and extra-cranial solid tumors in a descriptive design. Temozolomide was administered orally at 150 mg/m2 followed by topotecan at 0.75 mg/m2 intravenously for 5 consecutive days every 28 days. The main endpoint was objective response (OR), i.e., Complete or Partial Response (CR+PR), evaluated after 2 cycles according to WHO criteria, or INRC criteria for neuroblastoma patients with mIBG-positive lesions, by an independent radiological review. Independent review of mIBG imaging is pending. Results: 103 patients, median age 9.4 years (range 1-21), were treated between June 2009 and May 2011 in 18 centers: 38 neuroblastoma, 33 CNS tumors and 32 other solid tumors. Overall 420 cycles were administered (median 3 per patient; range 1-12). Grade 3 or 4 neutropenia was frequent (55% courses), though only 6% of patients developed febrile neutropenia. In the neuroblastoma cohort, 1 CR and 7 PR were observed, leading to an estimated OR rate of 21% (95%CI, 10-37%). Additionally 22 patients had disease stabilization (SD), leading to an overall tumor control (CR+PR+SD) of 79% (63-90%), and a 12-month progression-free survival rate of 47% (31-64%). Overall, 17/102 evaluable patients achieved an OR (17%, 10-25%), with 1 CR and 3 PR in 9 medulloblastoma (44%, 14-79%), 2 PR in 4 PNET, 1 PR in 12 malignant glioma, and 2 PR in 9 RMS. Conclusions: Temozolomide-topotecan combination results in significant tumor control in children with neuroblastoma and medulloblastoma/PNET with favorable toxicity profile.

14031 Background: Docetaxel (TXT) and S-1 are active agents against gastric cancer. A synergistic antitumor effect has been shown in a preclinical study (Takahashi et al., Oncology 2005), and our previous phase I trial demonstrated the safety and tolerability of the combination, and its potent activity. To prospectively evaluate toxicity and efficacy of S-1/ biweekly TXT, we conducted the current phase II study in patients with advanced and recurrent gastric cancer. Methods: Patients (pts) with advanced or recurrent gastric cancer, who have not received any chemotherapy except postoperative chemotherapy (not including S-1 or TXT), were eligible for the trial, and were treated with docetaxel 35 mg/m2 one hour iv infusion on day 1 and 15, and S-1 at a full dose of 80 mg/m2/day for two weeks every four weeks. Results: Thirty-five pts with measurable lesions (RECIST) (10 females, 25 males; performance status [PS] 0/1/2: 23/8/4, age 27–74, differentiated/undifferentiated adenocarcinoma: 19/16) have been enrolled. A total of 113 cycles were administered (median 3, range 1–6), and all pts were assessable for toxicity and efficacy. Grade 3–4 toxicities were: neutropenia in 20.0% (grade 4: 11.4%) of patients, leukocytopenia in 11.4% (grade 4: 0%), anemia in 5.7%, appetite loss in 8.6%, stomatitis in 8.6%, fever in 2.9%, and fatigue in 2.9%. All treatment related toxicities resolved, and no toxic death was reported. Thirteen partial responses (PR) were obtained, resulting in an overall response (OR) rate of 37.1% (95% CI: 0.22–0.55). Thirteen pts (37.5%) had stable disease, and 4 pts (12.5%) progressed. The tumor control rate was 74.3% (95% CI: 0.57–0.88). The median survival time (MST) and time to treatment failure (TTF) were 326 and 75 days, respectively. Conclusions: The combination of S-1/ biweekly TXT is active in advanced or recurrent gastric cancer, and can be given safely with proper management of adverse events even in outpatient clinic. S-1/ biweekly TXT is one of the most effective regimen to control metastatic gastric cancer with less toxicity. No significant financial relationships to disclose.

4538 Background: Patients (pts.) suffering from advanced gastric cancer have still a poor prognosis and treatment options are limited. In our previous phase II trial (AGMT-Gastric-1) we could show that the combination of oxaliplatin and irinotecan was well tolerated and showed an objective response rate of 58% (Anticancer Res 28:2901–2906, 2008). This chemotherapy regimen was tested in combination with cetuximab in a multicenter phase II trial. Methods: Oxaliplatin 85 mg/m2 biweekly and irinotecan 125 mg/m2 biweekly were combined with cetuximab 400 mg/m2 loading dose and subsequently weekly 250 mg/m2. 51 patients with histological proven unresectable and/or metastatic gastric adenocarcinoma were treated in a first line setting. Median age: 62 years (range 19–79 years), PS 0: 25 patients, PS 1+2 26 patients, single metastatic site: 24 patients, multiple metastases: 27 patients. Results: Frequently reported adverse events (more than 20% of pts.) were predominantly grade 1 or 2 and included neutropenia (35% of pts.), thrombocytopenia (33%), anemia (73%), nausea (45%), diarrhea (57%), alopecia (22%), and fatigue (37%). Grade 3 and 4 toxicities included neutropenia in 9/1 pts., thrombocytopenia in 1/0 pts., anemia in 3/1 pts., nausea in 2/0 pts., and diarrhea in 7/2 pts. Sensory neuropathy occurred mostly as grade 1 and 2 in 37% of pts., in 7 pts. grade 3 neurotoxicity was observed. Acneiform skin rash grade 1 / 2 / 3 / 4 was reported in 31% / 20% / 6% / 2% of pts. respectively. 16 pts. went off-study due to neutropenia (n=5), nausea/vomiting (n=1), diarrhea (n=1), progressive disease (n=3), toxic colon (n=2), and allergic reaction to cetuximab at first (n=2), second (n=1) or third infusion (n=1). 35 patients are assessable for response with 1 pt. (3%) showing a CR, 21 pts. (60%) a PR, 7 pts. (20%) a SD and PD in 6 pts. (17%). A disease control rate was achieved in 83%. Median time to progression was 24.8 weeks (n=29), median overall survival 38.1 weeks (n=32). Conclusions: The combination of oxaliplatin and irinotecan with cetuximab is feasible, safe and active in advanced gastric cancer. [Table: see text]

4039 Background: Intraperitoneal (IP) chemotherapy with taxanes provides sustained high local concentrations, and the efficacy of IP paclitaxel (PTX) has been shown in ovarian cancer. We previously reported the safety and efficacy of IP PTX plus systemic chemotherapy in clinical trials. Capecitabine/cisplatin (XP) is one of the standard regimens for the first-line treatment of advanced gastric cancer worldwide. We designed a new regimen combining IP docetaxel (DOC) with XP, and the recommended dose of IP DOC was determined to be 10 mg/m2 in a phase I study. A phase II study of XP plus IP DOC was performed in gastric cancer patients with peritoneal metastasis. Methods: Gastric cancer patients with peritoneal metastasis confirmed by diagnostic imaging, laparoscopy or laparotomy were enrolled. DOC was administered intraperitoneally at 10 mg/m2 on days 1 and 8. Cisplatin was administered intravenously at 80 mg/m2 on day 1, and capecitabine was administered at 1000 mg/m2 bid for 14 consecutive days, repeated every 21 days. The primary endpoint was the 1-year overall survival (OS) rate. Secondary endpoints were response rate, negative conversion rate on peritoneal cytology and safety. Results: Out of 50 patients enrolled, 48 patients received protocol treatment, and were evaluated for OS and toxicity. The median number of courses was 6 (range 1-15). The 1-year OS rate was 75% (95% confidence interval, 60-85%). The best overall response was stable disease in all the three patients with target lesions. Cancer cells ceased to be detected by peritoneal cytology in 28 (76%) of 37 patients. Nineteen patients underwent gastrectomy after response to chemotherapy. The incidences of grade 3/4 hematological and non-hematological toxicities were 42% and 48%, respectively. The frequent grade 3/4 toxicities included neutropenia (21%), leukopenia (8%), anemia (29%), anorexia (25%) and nausea (17%). Infection of the intraperitoneal port was observed in one patient. There were no treatment-related deaths. Conclusions: Combination chemotherapy of XP plus IP DOC regimen is well tolerated and active in gastric cancer patients with peritoneal metastasis. Clinical trial information: UMIN000016469.

Purpose Hepatocellular carcinoma (HCC) is a vascular tumor with poor prognosis. Given the reported activity of gemcitabine and oxaliplatin (GEMOX) in HCC and the potential benefits of targeting the vascular endothelial growth factor pathway with bevacizumab (B), a phase II study of GEMOX-B was undertaken to define efficacy and toxicity profiles in HCC patients. Patients and Methods Eligible patients had pathologically proven measurable unresectable or metastatic HCC. For cycle 1 (14 days), bevacizumab 10 mg/kg was administered alone intravenously on day 1. For cycle 2 and beyond (28 days/cycle), bevacizumab 10 mg/kg was administered on days 1 and 15, gemcitabine 1,000 mg/m2 was administered as a dose rate infusion at 10 mg/m2/min followed by oxaliplatin at 85 mg/m2 on days 2 and 16. Results Thirty-three patients were enrolled and 30 patients were assessable for efficacy. The objective response rate was 20%, and 27% of patients had stable disease. Median overall survival was 9.6 months (95% CI, 8.0 months to not available) and median progression-free survival (PFS) was 5.3 months (95% CI, 3.7 to 8.7 months); the PFS rate at 3 and 6 months was 70% (95% CI, 54% to 85%) and 48% (95% CI, 31% to 65%), respectively. The most common treatment-related grade 3 to 4 toxicities included leukopenia/neutropenia, transient elevation of aminotransferases, hypertension, and fatigue. Conclusion GEMOX-B could be safely administered with close monitoring and had moderate antitumor activity for patients with advanced HCC. The high 6-month PFS rate is encouraging, and this regimen is worthy of further investigation.
