406 Background: Zibotentan (Z) is an oral specific ETAR antagonist. The ETAR is over expressed in colorectal cancer, and pre-clinically, antagonism of the ETAR has been shown to enhance cytotoxicity when combined with cytotoxics such as 5-FU. This multi-center, randomized, double-blind, placebo-controlled phase II study evaluated the safety and anti-tumor activity of irinotecan and 5-FU (as the FOLFIRI regimen) in combination with Z in advanced colorectal cancer. Methods: Patients (pts) with advanced colorectal cancer who had progressed after oxaliplatin-containing chemotherapy (FOLFOX) were randomized (1:1) to receive 10 mg O.D Z/placebo (continuous dosing) with standard dose FOLFIRI for a maximum of 12 cycles. Z /placebo could be continued until progression or unacceptable toxicity in those patients with a documented response. The primary objective was progression–free survival (PFS) with secondary endpoints of safety and blood and archival tumor samples collected for translational work including circulating tumour cell (CTC) analysis. This study was run as part of the AZ/NCRN alliance, endorsed by Cancer Research UK (CRUKE/09/023) and coordinated by the Wales Cancer Trials Unit, Cardiff University. Results: A total of 111 patients were recruited: 61% men, median age of 62 years. Z was well tolerated with G3/4 toxicity balanced between both groups (34/55 patients in Z and 38/56 in placebo group). The study was terminated before the planned number of pts (122) were recruited due to lack of efficacy of the drug in two other tumour types. Median PFS was 4.0 months in the Z group and 7.4 months in the placebo group (HR=1.86, 95% CI 1.20 to 2.87, p=0.005). The CTC analysis in relation to outcome in the placebo group will be presented. Conclusions: Zibotentan does not have anti-cancer activity in combination with FOLFIRI in patients with colorectal cancer treated with previous FOLFOX. Taken in consideration with the other trial data we do not recommend the further development of zibotentan in oncology. Clinical trial information: 73199181.

602 Background: The Kyushu Study group of Clinical Cancer conducted a phase II study that evaluated the FIREFOX regimen. (KSCC0701, Akagi et al, J Clin Oncol 28:15s, 2010). This study demonstrated the efficacy and mild neurotoxicity of this regimen. The present study evaluated the efficacy and safety of the FIREFOX plus bevacizumab (bev). Methods: Eligibility criteria included histologically confirmed advanced colorectal cancer, ECOG PS 0-2 and adequate bone marrow, renal and hepatic function. Patients (pts) received an alternating regimen of 4 cycles of mFOLFOX-6 plus bev (oxaliplatin 85 mg/m2, leucovorin 200 mg/m2, bev 5 mg/kg d1 followed by 400 mg/m2 bolus 5-FU and a 46-hr 2,400 mg/m2 5-FU infusion every 2 weeks) followed by 4 cycles of FOLFIRI plus bev (oxaliplatin replaced with irinotecan 150 mg/m2 d1). This schedule was repeated until unacceptable toxicity or disease progression occurred. The primary endpoint is progression-free survival. (UMIN000001312) Results: Of the 52 pts enrolled from May 2008 to July 2009. Two of the patients did not fulfill the eligibility criteria. M/F, 30/20; median age, 59.5 years (range 37 - 75); ECOG PS 0/1/2, 46/4/0. The median number of administration cycles was 14 (range, 2 - 44). Response rate (RECIST criteria) for CR, PR, SD, PD and NE were 2 (4%), 28 (56%), 14 (28%), 4 (8%) and 2 (4%), respectively. An overall response rate was 60% (95% CI: 45 - 74%). Median progression-free survival was14.2 M (95% CI: 10.6 M-16.3 M) and median overall survival was 27.5 M (95% CI; 22.4 M – not determined). The 2-year survival rate was 56.8%. Of the 52 pts evaluated for toxicity. The most common grade 3-4 adverse events were leukopenia (7.7%), neutropenia (32.7%), anemia (1.9%), fatigue (9.6%), anorexia (13.5%), stomatitis (3.8%), neurotoxicity (3.8%), hypertension (1.9%), diarrhea (7.7%), febrile neutropenia (3.8%), nausea (9.6%), vomiting (5.8%), hypersensitivity (3.8%), and thromboembolism (1.9%). Conclusions: The results of this phase II study show that the FIREFOX plus bev regimen is effective and well tolerated in the first-line treatment of advanced colorectal cancer. The low rate of neurotoxicity is also promising.

TPS275 Background: Colorectal cancer (CRC) is the second leading cause of cancer-related death in US. The majority of US patients (pts) receive first-line therapy (Rx) with FOLFOX [Folinic acid (FA), 5-fluorouracil (5-FU) and oxaliplatin (Ox)] + a biologic, making FOLFIRI [FA+ 5-FU+ irinotecan (Iri)] + bevacizumab (Bev) a common second-line Rx. This regimen has a median progression-free survival (PFS) of approximately 6 months (mo) and overall survival (OS) of 12 mo. Further gains are desperately needed. Trifluridine/tipiracil (FTD/TPI) is an oral combination Rx of a thymidine-based nucleoside analogue, FTD, and a phosphorylase inhibitor, TPI. FTD/TPI has a distinct mechanism of action from 5-FU and in preclinical models can overcome 5-FU resistance via DNA incorporation, base excision repair pathway and glycosylation responses to DNA damage. Further, there is an additive effect in combination with Iri. FTD/TPI was FDA approved for use in refractory metastatic CRC (mCRC) based on phase III RECOURSE trial. Phase I data showed combination of FTD/TPI, Iri and Bev to be safe, and an efficacy signal was seen in dose-expansion cohort (NCT01916447). A 12.5% response rate, 83.4 % disease control rate and PFS of 7.9 mo was achieved. As this study largely assessed refractory pts, one might expect a greater efficacy in Iri naïve pts. To test this hypothesis, we are conducting a multi-center phase II study of FTD/TPI, Iri and Bev as second-line Rx in mCRC pts. Methods: Eligible pts have mCRC and received first-line Ox based Rx. Rx to be given in 28-day cycles: Iri (180 mg/m2) and Bev (5 mg/kg) on D1 & 15, and FTD/TPI (25 mg/m2) twice daily on D2-6 & 16-20. Response assessment via CT/MRI to be done q8 wks (RECIST 1.1). Rx to continue until disease progression or unacceptable toxicity. The primary objective is to estimate PFS. Secondary objectives include ORR, OS, and safety. Final analysis to be done either 12 mo after enrollment of the final pt or once all pts have progression, whichever occurs earlier. A total of 40 pts to be accrued, and enrollment to start in January 2020. This study was approved and funded by the National Comprehensive Cancer Network (NCCN) Oncology Research Program from general research support provided by Taiho Oncology, Inc.

Abstract Standard of standard of care for glioblastoma (GBM) remains unsatisfactory with universal disease recurrence and a median survival of < 2 years. Immune checkpoint inhibitors (ICI) have shown limited single-agent activity in GBM thus far. GBMs with methylated MGMT promoter and no baseline corticosteroid dependence may be most likely to derive benefit from ICI. The combination of ICIs with radiation has shown promising activity in other human cancers. Combining nivolumab and re-RT/bevacizumab in GBM may augment ICI activity through immunogenic effects of radiation, may reduce the risk of radiation necrosis by addition of bevacizumab at the time of radiation, and may reduce the need for corticosteroids. In this multicenter phase II study, nivolumab is combined with re-irradiation and optional concurrent bevacizumab followed by nivolumab in patients with first recurrence of IDH-wildtype and MGMT methylated glioblastoma. Primary objective is to improve 1-year overall survival (OS) from 33 (based on EORTC 26101) to 50%. Nine-three patients are required to show a significant finding with an α of 0.05 and 81% power. Thirteen of 93 patient (14%) have been enrolled with a median age of 59 (range 42–71) with a median KPS of 90 (range 70–90). Treatment has been tolerated well without any grade ≥ 4 toxicities and only one grade 3 (amylase elevation). The most common adverse events were pruritus and hypothyroidism in 3/13 (23%). The median progression-free survival (PFS) is 7 months with a 6months PFS of 55.6%. The 12months OS is 66.7%. Patients with recurrent MGMT methylated, IDH-wildtype glioblastoma tolerate trial treatment with acceptable toxicities. Clinical efficacy in the first patients enrolled shows a promising effect. Enrollment is ongoing.

Objective: The study investigated the efficacy and safety of oral vinorelbine-cisplatin (OV-CDDP) and gemcitabine-cisplatin (GEM-CDDP) in patients with squamous non-small cell lung cancer (sq-NSCLC). Patients and methods: This was an open-label, prospective, multicenter, international phase II study that enrolled untreated patients with advanced sq-NSCLC. Patients were randomized to receive 3-week cycles of either 60–80 mg/m2 OV days 1 and 8 in combination with 80 mg/m2 CDDP day 1 (arm A) or 1250 mg/m2 GEM days 1 and 8 in combination with 75 mg/m2 CDDP day 1 (arm B). After four cycles, patients without disease progression continued maintenance dose of OV or GEM until progression or unacceptable toxicity. The primary objective was disease control rate (DCR). Secondary objectives included progression-free survival (PFS), time to treatment failure (TTF), overall survival (OS), safety, and quality of life (QoL). Results: A total of 114 patients with sq-NSCLC were randomized, and 113 were treated (57 in arm A and 56 in arm B). DCR was high in both arms: 73.7% (95%CI: 62.4–100.0) in arm A and 75.0% (95%CI: 63.7–100.0) in arm B. Median PFS and TTF were similar in arm A and B 4.2 and 2.8 months, and 4.3 and 3.1 months, respectively. Even though the difference was not significant, the OS was 10.2 for arm A and 8.4 months for arm B. The safety profiles were consistent with the current knowledge of adverse events. QoL results revealed an improvement in patients under OV treatment. Conclusion: The OV-CDDP combination showed comparable efficacy to GEM-CDDP with acceptable safety profile and enhanced patients’ QoL. Trial registration: The study was registered under EudraCT number 2012-003531-40.
