112 Background: The phase III G-SOX trial had adopted SOX100 due to high incidence of thrombocytopenia in the previous phase I/II study, and failed to demonstrate the non-inferiority of SOX100 to S-1 plus cisplatin in chemotherapy-naïve Japanese pts with AGC. However, OX 130 mg/m2 has been approved for AGC in Japan since Sep 2014 on the evidence of the REAL-2 trial. Therefore, we conducted a study to evaluate the feasibility of SOX130 in Japanese AGC pts. Methods: This is a single-arm, open-label, multicenter, phase II study. Pts with unresectable or recurrent adenocarcinoma of stomach, no prior chemotherapy and ECOG PS 0 or 1 were treated with SOX130 (S-1 80-120 mg/day according to BSA for 2 weeks, OX 130 mg/m2 on day 1, every 3 weeks). The primary endpoint was the 3-cycle completion rate, defined as the proportion of pts who receive at least 80% of the planned OX dose for the first 3-cycle. We set the threshold 3-cycle completion rate at 50% and the expected rate at 75%. A sample size of 23 pts was needed with 80% power at a 5% α-level (one-sided). Results: From April 2015 to June 2016, 25 pts were enrolled. Pts’ characteristics were as follows: median age 64.5 years (range, 32-76), male/female 21/4, PS 0/1 15/10, unresectable/recurrent 21/4, and intestinal/diffuse 7/18. The 3-cycle completion rate was 72.0% (90% CI 53.8-86.1%). Among the 12 pts with measurable lesions, objective response rate and disease control rate were 58.3% and 83.3%, respectively. With a median follow-up period of 5.2 months, median progression-free survival was 7.5 months. Grade 3 adverse events were anorexia (n = 5), anemia (n = 3), thrombocytopenia (n = 2), neutropenia (n = 1) and nausea (n = 1). No treatment-related death was observed. Conclusions: SOX130 could be a first-line treatment option even in Japanese AGC pts. Clinical trial information: UMIN000016973.

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.

7100 Background: Amrubicin is a novel anthracycline associated with high objective response rates (ORR) in patients (pts) with relapsed SCLC. Amrubicin improved the ORR and progression-free survival (PFS) in relapsed SCLC vs. topotecan, but not overall survival (OS) in a phase III study. Amrubicin with cisplatin/carboplatin for elderly Japanese pts was safe and active. We conducted a multicenter phase II study evaluating amrubicin and carboplatin in newly diagnosed ES-SCLC. Methods: Eligible pts had untreated ES-SCLC, measurable/evaluable disease (RECIST v. 1.1) and an ECOG PS <2. Pts received 4 cycles of amrubicin 30 mg/m2 on days 1-3 and carboplatin AUC=5 both IV day 1 every 21 days with restaging every 6 weeks. Pegfilgrastim 6 mg sq was administered on day 4 of each cycle. The primary endpoint was 1-year OS. Secondary endpoints included ORR, PFS, OS, and toxicity. Results: 78 pts were enrolled from 3/2010 to 7/2011. Baseline characteristics included: median age 65 yrs (range 45-84); 56% female. 64% completed 4 cycles of treatment. Eleven (14%) pts showed complete responses and 47 (60%) pts partial responses, for an ORR of 74% (95% confidence interval 65%-82%). Twelve (15%) pts had stable disease. Median PFS and OS were 5.3 and 9.5 months, respectively. The 1-year OS was 36%. Grade 3/4 myelosuppression was the most common toxicity (thrombocytopenia 44%, neutropenia 34%, febrile neutropenia 12%, anemia 26%), but was manageable. Severe non-hematologic toxicities (>5%) included hypokalemia 17%, fatigue 13%, dehydration 10%, hyponatremia 10%, pneumonia 9%, and nausea/vomiting 8%. 1 pt died from sepsis and another from aspiration pneumonia. Conclusions: First-line ES-SCLC treatment with amrubicin and carboplatin induced several complete responses and is considered highly active. Myelosuppression was managed effectively with growth factor support. These results are comparable to historical data with platinum-doublet chemotherapy. A larger randomized study would be required to best assess this regimen’s impact on survival.

Summary Background. Pancreatic neuroendocrine tumors (NETs) are rare but are frequently diagnosed at advanced stages and require systemic therapy. Patients and methods. This multicenter, open-label, phase II study evaluated sunitinib in Japanese patients with well-differentiated pancreatic NET. Patients received sunitinib 37.5 mg/day on a continuous daily dosing (CDD) schedule. The primary endpoint was clinical benefit rate (CBR; percentage of complete responses [CRs] plus partial responses [PRs] plus stable disease [SD] ≥24 weeks). Secondary endpoints included objective response rate (ORR), tumor shrinkage, progression-free survival (PFS) probability, safety, pharmacokinetics, and biomarkers. Results. Twelve patients received treatment. The CBR was 75 % (95 % confidence interval [CI], 43–94) and included 6 patients with a PR and 3 with SD. The ORR was 50 % (95 % CI, 21–79). PFS probability was 91 % (95 % CI, 54–99) at 6 months and 71 % (95 % CI, 34–90) at 12 months. Commonly reported treatment-emergent (all-causality), any-grade adverse events included diarrhea (n = 10), hand–foot syndrome and hypertension (both n = 8), fatigue and headache (both n = 7), and neutropenia (n = 6). No deaths on study were reported; one death due to disease progression occurred >28 days after end of treatment. Sunitinib on a CDD schedule resulted in sustained drug concentrations without accumulation across cycles. Tumor responses in all 12 patients did not appear to correlate with decreases in chromogranin A levels. Conclusions. Sunitinib 37.5 mg/day on a CDD schedule demonstrated antitumor activity in Japanese patients with unresectable, well-differentiated pancreatic NET. Commonly reported adverse events were consistent with the known safety profile of sunitinib.

485 Background: Vascular endothelial growth factor receptor inhibitors, including axitinib (AG-013736), may be useful in treating patients with mCRC. The goals of this study were to estimate the objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and safety in patients with mCRC treated with mFOLFOX-6 combined with axitinib or bevacizumab or both. Methods: Patients with mCRC untreated with any systemic chemotherapy >12 months prior to enrollment, ECOG PS 0/1, adequate organ function, and controlled hypertension were eligible for this randomized, open-label, phase II study. Patients receiving prior treatment with antiangiogenic agents or those who were pregnant were ineligible. All patients received standard mFOLFOX-6 treatment and were randomized to receive either axitinib 5 mg (Arm A), or bevacizumab 5 mg/kg (Arm B), or axitinib 5 mg + bevacizumab 2 mg/kg (Arm C). Axitinib was administered orally twice daily. Efficacy was determined by RECIST criteria. Results: A total of 42, 43, and 41 patients were enrolled in Arms A, B, and C, respectively. The ORR was 29%, 49%, and 39% for Arms A, B, and C, respectively. Median PFS was 315 days, 350 days, and 377 days, with 1-year survival of 72%, 79%, and 80% for Arms A, B, and C, respectively. Discontinuations due to adverse events (AEs) were more common in Arm A (36%), than in Arms B (19%) or C (32%). More patients withdrew from Arm A (18%) than from Arms B (5%) or C 12%). The rates of grade 3 AEs were similar across arms, except for hypertension and fatigue which were more common in Arms A (15% and 12%) and C (21% and 29%) compared with Arm B (2% and 12%). Serious AEs were reported by 41%, 40%, and 56% of patients in Arms A, B, and C, respectively; the most common were gastrointestinal disorders (21%, 16%, 15%, respectively). Conclusions: In combination with mFOLFOX-6 chemotherapy, treatment with axitinib resulted in a lower ORR but comparable survival to bevacizumab and this did not appear to improve significantly in the presence of both agents. This result may have been affected by the higher numbers of discontinuations and withdrawals in Arm A compared with the other 2 arms. [Table: see text]

707 Background: VEGF promotes tumor angiogenesis and metastasis. Z blocks the activity of VEGF-A/-B, and placental growth factor and was shown in the VELOUR phase III study (NCT00561470) outside of Japan to significantly improve overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) in mCRC pts as a second-line treatment given with FOLFIRI. Goals of the current open-label, multicenter phase II study were to assess the efficacy and safety of Z + FOLFIRI in a post-oxaliplatin setting in mCRC pts in Japan. Methods: Pts received Z (4 mg/kg) + FOLFIRI (400 mg/m2 bolus 5-fluorouracil [FU]; 2400 mg/m2 continuous infusion 5-FU; 200 mg/m2 levofolinate; 180 mg/m2 irinotecan) every 2 weeks until progression, unacceptable toxicity, or study withdrawal. Primary endpoint: ORR (required 60 pts in order to obtain a 95% CI width of 16–20%, assuming an ORR of 10–20%). Secondary endpoints: PFS, OS, and safety. Tumors were assessed by independent reviewers every 6 ± 1 weeks until progression. Results: Study enrolled 62 pts; 50 pts (83.3%) had received prior bevacizumab. Of 60 pts evaluable for response, 5 had a partial response and none had a complete response, resulting in an ORR of 8.3% (95% CI: 1.3–15.3%). The median PFS was 5.42 months (95% CI: 4.140–6.702), and the median OS was 15.59 months (range 11.20–19.81). Forty-one pts (66.1%) died due to progression; none died due to study treatment. Pts underwent a median of 8 treatment cycles (range 1–31) lasting a median of 21.8 weeks (range 2–73). The median relative dose intensity was 0.99 (range 0.2–1.0) for Z, 0.87 (range 0.4–1.0) for irinotecan, and 0.96 (range 0.7–1.0) for 5-FU. All pts had ≥1 treatment emergent adverse event (TEAE; see table). Conclusions: The ORR was 8.3% (95% CI: 1.3–15.3%), and the median OS was 15.59 months. The safety profile was consistent with that reported previously. Registered as NCT01882868. Clinical trial information: NCT01882868. [Table: see text]

PURPOSE Mucosal melanoma (MM) is a highly vascularized tumor with an extremely poor prognosis. In this randomized, open-label, phase II study, we characterized the efficacy and safety of bevacizumab in combination with carboplatin plus paclitaxel (CPB) in patients with previously untreated advanced MM. PATIENTS AND METHODS Patients were randomly assigned in a 2:1 ratio to receive carboplatin (area under the curve, 5) plus paclitaxel (175 mg/m2) once every 4 weeks in combination with (CPB arm, 5 mg/kg) or without (CP arm) bevacizumab once every 2 weeks. Progression-free survival (PFS) was the primary end point. Secondary end points included overall survival (OS), objective response rate, and adverse events. RESULTS We recruited 114 patients to our study. The median PFS was significantly longer in the CPB arm (4.8 months; 95% CI, 3.6 to 6.0 months) than in the CP arm (3.0 months; 95% CI, 1.7 to 4.3 months) (hazard ratio, 0.461; 95% CI, 0.306 to 0.695; P < .001). Objective response rates were 19.7% and 13.2%, respectively ( P = .384). The median OS was also significantly longer in the CPB arm than in the CP arm (13.6 v 9.0 months; hazard ratio, 0.611; 95% CI, 0.407 to 0.917; P = .017). No new safety signals were observed. CONCLUSION PFS and OS were significantly better in patients with metastatic MM who received bevacizumab in addition to CPB than in those who received CPB alone. A phase III study should be performed to confirm these benefits (ClinicalTrials.gov identifier: NCT02023710 ).

TPS2103 Background: EGFRvIII is a constitutively active tumorigenic deletion mutation of EGFR. It is expressed in ~30% of primary GB where it is linked to poor long-term survival (Pelloski 2007). The investigational vaccine rindopepimut consists of the unique EGFRvIII peptide sequence conjugated to keyhole limpet hemocyanin (KLH), delivered intradermally (500ug with 150ug GM-CSF as an adjuvant). Remarkably consistent and promising results across 3 phase II studies in newly diagnosed, resected EGFRvIII+ GB (Lai 2011) represent a statistically significant improvement over a historical control cohort matched for major eligibility criteria (median overall survival [OS] = 24.4 - 24.6 vs. 15.2 months from diagnosis [m] and median progression-free survival [PFS] = 12.3 - 15.3 vs. 6.4 m). ACT IV, a phase III trial in this population, is ongoing. The immunosuppressive influence of residual/advanced GB presents a challenge to activation of efficacious antitumor immune responses. Anecdotal evidence (compassionate use cases, Sampson 2008) suggests that rindopepimut may induce specific immune responses and regression in multifocal and bulky residual tumors. Rindopepimut with BV, which inhibits VEGF and its immunosuppressive properties (including impaired maturation of dendritic cells and disruption of tumoral T cell infiltration [Johnson 2007, Shrimali 2010]) may further optimize EGFRvIII-specific immune response and antitumor activity. Methods: ReACT is a Phase II study of rindopepimut plus BV in patients (pts) with 1st or 2nd relapse of EGFRvIII+ GB. BV-naïve pts will be enrolled to Group 1 (n=70: randomized 1:1 to BV plus either rindopepimut/GM-CSF or control injection [low-dose KLH]) while BV-refractory patients will enter Group 2 (n=25: to receive BV plus open-label rindopepimut/GM-CSF). Concurrent with BV (10 mg/kg, q 2 wks), blinded treatment or open-label vaccine is given in priming phase (days 1, 15 and 29), then monthly until PD. Tumor response is assessed every 8 weeks, and patients are followed for survival after PD. Objectives are PFS at 6 months (primary), objective response rate, PFS, OS, safety, immunogenicity and elimination of EGFRvIII. ReACT opened to accrual in December 2011 (NCT01498328).

454 Background: Pmab has demonstrated significant improvement in progression-free survival (PFS) in pts with WT KRAS mCRC as 2nd-line tx in a phase III trial comparing pmab + FOLFIRI vs FOLFIRI alone. Here, we describe the results of SPIRITT, a multicenter, randomized phase II study evaluating pmab + FOLFIRI and bev + FOLFIRI in pts with WT KRAS mCRC previously treated with a 1st-line bev + oxaliplatin (Ox)-based chemotherapy regimen. Methods: Pts were randomized 1:1 to pmab 6.0 mg/kg + FOLFIRI Q2W or to bev 5.0 or 10.0 mg/kg + FOLFIRI Q2W. Eligibility criteria included: WT KRAS mCRC, ECOG ≤ 1, no prior irinotecan or anti-EGFR tx, and tx failure of prior 1st-line bev + Ox-based therapy (≥ 4 cycles). The primary endpoint was PFS; secondary endpoints included overall survival (OS), objective response rate (ORR), and safety. No formal hypothesis was tested. Results: 182 pts with WT KRAS mCRC were randomized. All pts received tx. Efficacy results are shown (table). Worst grade of 3/4 adverse events (AE) occurred in 78% of pts in the pmab + FOLFIRI arm and 65% in the bev + FOLFIRI arm. Grade 5 AEs occurred in 7% of pts in the pmab + FOLFIRI arm and 7% in the bev + FOLFIRI arm. Tx discontinuation due to any AE was 29% in the pmab + FOLFIRI arm and 25% in the bev + FOLFIRI arm. Conclusions: In this estimation study of pts with WT KRAS mCRC that previously received bev + Ox-based tx, the PFS hazard ratio (HR) was 1.01 (95% CI: 0.68 - 1.50). The OS HR was 1.06 (95% CI: 0.75 - 1.49). The observed ORR was higher in the pmab + FOLFIRI arm. 54% of bev + FOLFIRI pts received subsequent anti-EGFR tx. The safety profile for both arms was similar to previously reported studies. Tx discontinuation rates due to AEs were similar between the arms. Clinical trial information: NCT00418938.

7106 Background: E7389, a synthetic analog of halichondrin B that was isolated from a marine sponge, has broad anti-proliferative activity at nanomolar levels and a unique profile of tubulin interactions. Methods: This is an open-label, single-arm, stratified phase II study of E7389 in patients with measurable, recurrent and/or metastatic NSCLC who progressed during or after platinum-based doublet chemotherapy. E7389 (1.4 mg/m2) was administered as a bolus IV on days 1, 8, and 15 of a 28-day cycle to 72 patients (cohort 1) in stratum I (55 taxane pretreated patients) and stratum II (17 taxane-naive patients) and on Days 1 and 8 of a 21-day cycle (cohort 2), providing an additional 22 patients in stratum I. The primary efficacy endpoint was objective response rate to E7389 monotherapy. Results: As of 9 December 2005, 94 evaluable patients received E7389. Nineteen tumors were classified as squamous cell carcinomas, 39 as adenocarcinomas, and 36 were large cell carcinomas or unclassified. The median number of cycles completed was 3. Fifteen patients completed 6 or more cycles and 75 patients underwent tumor assessments after cycle 2. Major toxicities related to study drug included myelosuppression, nausea, fatigue, dehydration, arthralgias, dyspnea, and peripheral neuropathy. Based on RECIST criteria, 6 partial responses (PR) were observed among 94 evaluable patients (PR rate = 6.4%, 95% CI: 2.8%, 12.8%). For 33 patients the best response was stable disease (SD rate = 35.1%, 95% CI: 25.5%, 45.1%). Disease control rate (PR + SD) was 41.5% (95% CI: 31.4%, 51.7%). For cohort 1, the 12-week progression free survival rate was 57.2%. As of 9 December 2005, median PFS time was 108 days (95% CI = 55, min-max = 1–239+). Cohort 2 is being followed to estimate their 12-week PFS. The correlation of beta tubulin isotype, stathmin, microtubule-associated protein 4 (MAP4) and tau protein mRNA expression with tumor responses is on-going. Conclusions: Based on this data, E7389 has been shown to be safe and effective in the treatment of NSCLC patients. Updated information and results of molecular correlations of responses will be presented. [Table: see text]

260 Background: Recent placebo-controlled phase III trials of the mTOR inhibitor everolimus and the VEGF/ PDGF receptor inhibitor sunitinib in PNET noted improved progression-free survival (PFS). However, objective response rates (RR) with these agents are <10%. Preclinical studies suggest enhanced anti-tumor effects with combined mTOR and VEGF targeted therapy. Methods: We conducted a phase II trial of the mTOR inhibitor TEM (25 mg IV q week) and the VEGF-A monoclonal antibody BEV (10 mg/kg IV q 2 weeks) in patients (pts) with well or moderately differentiated PNET and progressive disease by RECIST within 7 months of study entry. Co-primary endpoints were RR and 6-month PFS. Planned enrollment is 50 patients, with interim analysis after the first 25 evaluable pts. Pts had no prior mTOR or VEGF targeted agents, ECOG PS 0-1, and adequate hematologic and organ function. Continued octreotide was allowed, but not required. Prior interferon, embolization, and ≤ 2 chemotherapy regimens were allowed. Results: Confirmed PR was documented in 11 of the first 25 (44%) evaluable patients. 20 of 25 (80%) patients were progression-free at 6 months. Both endpoints exceeded pre-defined criteria to continue enrollment. For 35 evaluable patients, the most common grade 3-4 adverse events attributed to therapy were leukopenia (12%), hypertension (12%), hyperglycemia (12%), mucositis (9%), and fatigue (9%). Conclusions: The combination of TEM/BEV has substantial activity in a multi-center phase II trial with RR of 44%, well in excess of single targeted agents in PNET. 6-month PFS was a notable 80% in a population of patients with RECIST criteria progression within 7 months of study entry.
