4019 Background: Targeting a single pathway in pancreatic adenocarcinoma (PAC) is unlikely to impact its natural history. EGFR targeting with erlotinib added to gemcitabine (G) marginally improved the outcome of patients with advanced disease. We tested the hypothesis that if the EGFR and IGF-1R pathways are simultaneously blocked then progression free survival (PFS) would be significantly improved by abrogating reciprocal signaling that leads to resistance to either drug. Methods: This was a phase I/randomized phase II (RP2) study testing the anti-IGF-1R monoclonal antibody cixutumumab combined with erlotinib and G in patients with metastatic PAC. The control arm was erlotinib plus G. The primary endpoint of the RP2 portion of the study was PFS. Eligibility included patients with untreated metastatic disease, performance status 0/1, fasting blood glucose less than institutional upper limit of normal, and willingness to provide tissue and blood specimens for correlative studies. Results: In phase I portion (n=10) safety of cixutumumab 6 mg/kg IV/wk, erlotinib 100 mg/day orally and G 1000 mg/m2 IV D 1, 8, and 15 of a 28-day cycle was established. In the RP2 portion (n=124) 114 eligible patients (median age 63) were included. On the cixutumumab arm, 59% of patients were female vs. 40% on control arm. Median PFS and overall survival were 3.7 and 6.7 months, respectively, in both arms of the study. Major grade 3 and 4 toxicities were (cixutumumab/control) elevation of transaminases (12%/6%), fatigue (16%/12%), gastrointestinal (35%/28%), neutropenia (21%/10%), and thrombocytopenia (16%/7%). Grade 3/4 hyperglycemia was seen in 16% of patients on cixutumumab. Grade 3 or 4 kin toxicity was similar in both arms of the study (< 5%). Five treatment-related deaths were reported: 2 cardiac on each arm, 1 pulmonary on cixutumumab. Conclusions: IGF-1R inhibitor cixutumumab did not improve the progression free or overall survival of patients with metastatic PAC treated with erlotinib and G in a molecularly unselected population.

198 Background: Targeting a single pathway in pancreatic adenocarcinoma (PAC) did not impact the natural history of this molecularly complex disease. Epidermal growth factor receptor (EGFR) targeting with erlotinib marginally improved the outcome of patients with advanced disease. We tested the hypothesis that if the EGFR and IGF-1R pathways are simultaneously blocked then progression free survival (PFS) would be significantly improved by abrogating reciprocal signaling. Methods: S0727 was a phase I/randomized phase II (RP2) study testing the anti-IGF-1R monoclonal antibody cixutumumab combined with erlotinib and gemcitabine in patients with metastatic PAC. The control arm was erlotinib plus gemcitabine. The primary endpoint of the RP2 portion of the study was PFS. Eligibility included patients with untreated metastatic disease, performance status 0/1, fasting blood glucose less than institutional upper limit of normal, and willingness to provide tissue and blood specimens for correlative studies. Results: In Phase I portion (n=10) safety of cixutumumab 6 mg/kg IV/wk, erlotinib 100 mg/day orally and gemcitabine 1000 mg/m2 IV D 1,8, and 15 of a 28-day cycle was established. In the RP2 portion (n=124) 114 eligible patients (median age 63) were included. On the cixutumumab arm, 59% of patients were female vs. 41% on control arm. Median PFS and overall survival were 4 and 7 months, respectively, in both arms. Four patients on cixutumumab remain on treatment; sensitivity analyses show no impact on the conclusions. Major grade 3 and 4 toxicities were (cixutumumab/control) elevation of transaminases (12%/6%), fatigue (24%/21%), gastrointestinal (35%/28%), and hematologic (53%/39%). Grade 3/4 hyperglycemia was seen in 27% of patients on cixutumumab. Grade 3 or 4 kin toxicity was similar in both arms of the study (< 5%). Five treatment-related deaths were reported: 2 cardiac on each arm, 1 pulmonary on cixutumumab. Conclusions: IGF-1R inhibitor cixutumumab did not improve the progression free or overall survival in patients with metastatic PAC treated with erlotinib and gemcitabine in a molecularly unselected population.

3545 Background: Cytotoxic chemotherapy with targeted therapy against the vascular endothelial growth factor (VEGF) or the epidermal growth factor receptor (EGFR) has become a standard approach in MCRC, though combining VEGF and EGFR inhibition with chemotherapy as initial treatment is not well established. We conducted a phase II study of the combination of infusional 5-fluorouracil (5-FU), leucovorin, oxaliplatin (FOLFOX), bevacizumab, and erlotinib in chemotherapy naïve patients with MCRC. Methods: Eligible patients had measurable MCRC, no prior systemic therapy for MCRC or at least one year since completion of adjuvant therapy (only 5-FU and leucovorin acceptable), performance status 0–1. The regimen consisted of 14-day cycles of FOLFOX started on day 1 (oxaliplatin 85 mg/m2, bolus 5-FU 400 mg/m2, leucovorin 400 mg/m2 and 46-hour infusion 5-FU 2.4 g/m2), day 1 bevacizumab 5 mg/kg and erlotinib 150 mg daily. This isa single stage trial with goal of 35 patients. The primary endpoint was progression-free survival (PFS). Results: Between Jan and Dec 2005, 31 patients have been enrolled with the following characteristics: male/female, 19/12; PS ECOG 0/1, 15/16; median age 58, range 38–81. Of the 28 patients who completed at least 1 cycle, the most common grade 3/4 adverse events include: 8/28 (29%) diarrhea, 8/28 (29%) neutropenia, 5/28 (18%) rash, 4/28 (14%) fatigue, 3/28 (11%) nausea/vomiting, 3/28 (11%) neuropathy. 22/28 (78%) of patients had at least 1 grade 3/4 toxicity. 14/31 patients remain on trial, 13/31 (42%) came off for toxicity or withdrew consent due to treatment-related toxicities, 4 withdrew consent for other reasons. Efficacy data is not available at time of submission but will be more mature by June 2006. Conclusions: The combination of FOLFOX, bevacizumab and erlotinib appears to have moderate toxicity, with ∼40% of patients coming off trial due to side effects. Further characterization of the tolerability profile will be necessary when interpreting the efficacy of the combination. We expect full accrual as well as reasonable point estimates of PFS by June 2006. Supported by: Sanofi-Synthelabo, a member of the Sanofi-Aventis group, Genentech [Table: see text]

4504 Background: Treatment options for metastatic NET, including islet cell carcinoma (ICC) and carcinoid tumor (CT), are limited. These tumors frequently express vascular endothelial growth factor receptor-2 (VEGFR-2) and platelet derived growth factor receptor receptor-β (PDGFR-β). Sorafenib, a small-molecule inhibitor of the VEGFR-2 and PDGFR-β tyrosine kinase domains, is a rational targeted therapy to evaluate in NET. Methods: Eligibility criteria included: ECOG PS = 2, = 1 prior chemotherapy, good organ function and signed informed consent. Prior interferon and prior or concurrent octreotide at a stable dose were allowed. Pts unable to take oral medications, with uncontrolled hypertension or with symptomatic coronary artery disease were excluded. Pts received sorafenib 400 mg po BID. Primary endpoint was response by RECIST in two cohorts (ie, CT and ICC) using separate 2-stage phase II designs. Results: 93 pts were enrolled: (50 CT, 43 ICC). For pts evaluable for the primary endpoint, 4 of 41 (10%) CT pts and 4 of 41 (10%) ICC pts had a PR. There were 3 minor responses (MR = 20–29% decrease in sum of target lesion diameters) in CT pts and 9 MRs in ICC pts for PR+MR rate of 17% for CT pts and 32% for ICC pts. For pts evaluable, 6-month progression-free survival was observed in 8/20 CT and 14/23 ICC pts. Grade 3–4 toxicity occurred in 43% of pts, with skin (20%), GI (7%) and fatigue (9%) most common. Translational studies from tumor tissue will be presented. Conclusions: Sorafenib at 400 mg po BID has modest activity in metastatic neuroendocrine tumors, with frequent grade = 3 toxicity.

72^ Background: Gastric cancer (GC) is the second leading cause of cancer death in Japan as well as globally. Effective treatment of GC remains a therapeutic challenge. Although in the AVAGAST trial, bevacizumab was found to offer no survival benefit. Angiogenesis continues to be the standard treatment for GC, and thus, clinical trials on many anti-angiogenic drugs have been conducted. TSU-68 (orantinib) is an oral, angiokinase inhibitor targeting the vascular endothelial growth factor receptor 2, platelet-derived growth factor receptor β, and fibroblast growth factor receptor 1. The present study evaluated the progression-free survival (PFS) and pharmacokinetics (PK) of TSU-68 in combination with Japanese standard S-1 and cisplatin (S-1/CDDP) in patients with advanced GC. Methods: In this open-label, multicenter, randomized, controlled, parallel-group, phase II trial, patients were randomized to Arm A (S-1/CDDP) or Arm B (TSU-68 plus S-1/CDDP). All patients received oral S-1 (40-60 mg/m2) twice daily for 21 days followed by a 14 day rest plus intravenous CDDP (60 mg/m2) on Day 8, repeated every 35 days. In Arm B pts received oral TSU-68 (400 mg/dose) alone, twice daily by addition 35 days. The primary endpoint was PFS. Results: In total, 93 patients were enrolled. For Arm A [male:female ratio], n=47 [35:11]; Arm B, n=45 [30:15]; the respective median age was 63.5 and 62.0 years. The median PFS was 7.0 and 6.8 months in Arms A and B, respectively (HR, 1.23; 95%CI, 0.74 to 2.05; P=0.425); the respective response rates were 56.5% and 62.2%. The most common grade 3/4 toxicities were neutropenia (Arms A and B, 34.8% and 31.1%) and hemoglobin (Arms A and B, 26.1% and 48.9%). There were no differences in other toxicities between the 2 arms, both treatments were tolerated, and no treatment-related deaths were observed. In the PK study, although Arm B had a significantly lower plasma exposure to FT, CDHP, and Oxo compared to Arm A, the exposure to 5-FU was not different between the 2 arms. The exposure to CDDP in Arm B was significantly but slightly lower than that in arm A. Conclusions: Thus,TSU-68 plus S-1/CDDP therapy did not prolong PFS of patients with advanced GC as compared with S-1/CDDP. Clinical trial information: JapicCTI-101327.

6013 Background: Cetuximab monotherapy results in a median overall survival (OS) of approximately 6 months (mo) in platinum-resistant recurrent/metastatic head and neck squamous cell carcinoma (HNSCC). HNSCC unrelated to human papillomavirus (HPV) is driven by hyperactivation of the CDK4/6 and cyclin D1 (CD1) regulatory complex, resulting in cell cycle progression and tumor growth, suggesting that CDK4/6 inhibition can be a rational therapeutic strategy in this setting. Palbociclib (PAL) is a selective CDK4/6 inhibitor that may reverse cetuximab resistance by countering the actions of deregulated CD1. PAL plus an epidermal growth factor receptor inhibitor synergistically reduced cell viability of HPV-unrelated HNSCC cell lines. In a single-arm, multicenter trial of platinum-resistant, cetuximab-naive, HPV-unrelated HNSCC, PAL in combination with cetuximab resulted in a median OS of 9.5 mo. Methods: In a double-blind randomized phase II trial, patients (pts) with platinum-resistant, cetuximab-naïve, HPV-unrelated HNSCC were treated with cetuximab plus either PAL (arm A) or placebo (arm B). Pts were stratified by performance status (PS) and prior immunotherapy (IT). 120 pts were required for 1:1 randomization to have ≥ 80% power to detect a hazard ratio (HR) of 0.6 (corresponding to a median OS of 10 mo in arm A and 6 mo in arm B) using a 1-sided log-rank test P=0.10). Key secondary endpoints included progression-free survival (PFS), adverse events (AEs), and p16 status. Results: Pts (n=125) were randomized (arm A, 65; arm B, 60). PS and prior IT were balanced between the arms. Median (95% CI) follow-up for OS was 15.9 (15.0–19.4) mo. Median OS was 9.7 (7.3–13.9) mo in arm A and 7.8 (6.7–10.6) mo in Arm B (stratified by PS: HR=0.82 [95% CI, 0.54–1.25], P=0.18). Median PFS was 3.9 mo in arm A and 4.6 mo in arm B (stratified by PS: HR=1.00 [0.7–1.5], P=0.5). Hematologic AEs were more common in arm A. Only 11 pts (9%) received IT after being treated on the trial. Conclusions: Among pts with platinum-resistant, HPV-unrelated HNSCC, PAL plus cetuximab resulted in a trend of prolongation of median OS compared with cetuximab. Clinical trial information: NCT02499120.

4028 Background: HCC is a vascular tumor with poor prognosis. Although S has been shown to improve survival, its ability to induce tumor shrinkage is very low. Given the activity of Gemcitabine and Oxaliplatin (GEMOX) in HCC, a phase II trial combining S with GEMOX was undertaken to define efficacy and safety profile. Methods: Patients with inoperable advanced and/or metastatic HCC (BCLCC B or C), with or without prior palliative chemoembolization, Child pugh score A, WHO performance status (PS) 0-1, were eligible for this two-stage, randomized phase II trial. Patients received S (400 mg BID) alone (arm A) or in combination with GEMOX every 2 weeks (gem. 1000 mg/m² [10 mg/m²/min] on D1; oxaliplatin, 100 mg/m² on D2) (arm B). Randomization was stratified according to CLIP score (0-1 vs. 2-3) and center. Primary endpoint was crude 4-mo Progression-Free Survival (PFS) rate (H0, < 50%; H1, ≥ 70%; α = 10%; 1- β= 90%). Results: From Dec 2008 to Oct. 2011, 94 pts were enrolled: median age, 64 yrs; male, 88%; PS 0 (69%) 1(31%), CLIP 0-1 (48%) 2-3 (52%), cirrhosis (63%), portal vein thrombosis (29%), extra liver metastasis (69%). These characteristics were well balanced in both arms. Median duration and dose intensity of S were 4 mo (1-27) and 81% in both arms, respectively. Median number of GEMOX cycles was 7 (1-12) in arm B. Main severe (grade 3-4) toxicity (arm A/B) consisted of neutropenia (grade 3-4: 0%/7%), fatigue (18%/24%), thrombocytopenia (0%/9%), diarrhea (grade 2-4: 10%/21%), peripheral neuropathy (grade 2-3: 0%/10%), and hand foot syndrome (grade 2-3: 13%/7%). For evaluable pts (n = 83), ORR was 9% / 16% and DCR was 70%/77% in arms A/B, respectively. For all pts (median follow-up, 17.6 mo), 4-mo PFS rate was 54%/61%, median PFS was 4.6 (3.9-6.2)/6.2 (3.8-6.8) mo, and median OS was 13.0 (10.4-22.2) /13.5 (7.5-19.1) mo in arms A/B, respectively. Conclusions: S plus GEMOX was feasible in HCC. This trial met its primary endpoint (4-mo PFS ≥ 50%) and ORR, median PFS and OS were encouraging data. Exploratory analyses are underway to identify subgroups of patients likely to derive most benefit from this combination. Clinical trial information: NCT00941967.

Abstract Background Preclinical data suggest sequential administration of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) following chemotherapy may improve efficacy. We hypothesized that intermittent delivery of EGFR-TKI following chemotherapy may increase efficacy. Methods This was a multicenter, single-arm phase I/II study to evaluate the efficacy of intermitted erlotinib in combination with docetaxel in patients with EGFR-negative NSCLC who failed one prior chemotherapy. The phase I primary objectives were to determine the maximum tolerated dose (MTD) and recommended dose (RD) of erlotinib. Erlotinib was administered orally once per day on days 2–16 in combination with 60 mg/m2 docetaxel on day1 for 21 days. A standard 3 + 3 dose escalation design was employed for erlotinib from 100 to 150 mg/dose. The phase II primary endpoint was the objective response rate (ORR). The ORR and 95% confidence interval (CI) were calculated using a binomial distribution. This study required 45 patients. Results In the phase I part, the planned dose escalation was completed without reaching MTD. The RD of erlotinib was determined as 150 mg/dose. In the phase II part, the ORR and disease control rate were 17.1% (95%CI: 7.2–32.1%) and 53.7% (95%CI: 37.4–69.3%), respectively. Median progression-free survival and overall survival were 3.5 (95%CI: 3.1–4.5) and 11.3 (95%CI: 8.6–16.6) months, respectively. The common non-hematological adverse event was febrile neutropenia (grade 3–4:19.6%). Two treatment-related deaths were occurred because of interstitial lung disease and pleural infection. Conclusions Intermittent dosing of erlotinib plus docetaxel is clinically feasible in phase I part but did not significantly improve ORR in phase II part.

3031 Background: In an effort to enhance the efficacy of vascular endothelial growth factor (VEGF) pathway blockade in mRCC we initiated a Phase I-II trial of combination S and B to block VEGFR signaling and VEGF binding, as well as, platelet derived growth factor receptor β (PDGFR) signaling. Methods: Pts with measurable (RECIST) mRCC, adequate organ function, and PS 0–1 were eligible for this trial. Cohorts of 6 pts were enrolled at 3 sites to define the MTD and DLT of the combination of S and B. The schedule was B IV q 14 days and S daily with cycles of 28 days. Response and toxicity were assessed at the end of 2 cycles. Dose levels began with S at 200mg BID and B at 5 mg/kg (level 1) with the hope to reach phase II doses of both agents (S at 400mg BID and B at 10mg/kg). The MTD or the phase II dose of each agent would then be administered to up to 45 pts with mRCC, clear cell histology, and prior nephrectomy. Results: A total of 18 patients have been enrolled to date, with 15 completing their first response evaluation. Pts were median age 61 years (46–74 range); M/F: 15/3; PS: 0/1= 12/6; 17 clear cell, 1 chromophobe, 11 prior nephrectomy; 4 with prior cytokine therapy. Two pts in level 1 experienced DLT with recurrent and intolerable (grade 3) hand-foot syndrome (HFS). An additional 6 patients were treated at dose level -1 (S at 200mmg QD and B at 3mg/kg) with no DLTs. Six more pts have been treated at dose level 1 with Vit B6 at 300mg/d in an attempt to minimize HFS. Toxicity data in this cohort is incomplete. Additional toxicities among the 18 pts included grade 3 hypertension (4), grade 3 proteinuria (2), and grade 2 stomatitis (3). Responses including 4 objective PRs, and 4 pts with 20–30% regression have been seen in the 14 evaluated pts. Only 2 patients have had disease progression. Conclusions: The phase II doses for this combination have not yet been established, but will likely be lower than the full phase II doses of the individual agents. The toxicities from HFS (primarily) and hypertension and stomatitis appear to be limiting. Even at the initial low doses of S and B, significant anti-tumor activity has been observed. The completion of this phase I trial will be reported. The phase II studies in mRCC are highly anticipated. Support by phase I contract UO-1 CA099177 [Table: see text]

The Impact

359 Background: Statins are HMG-CoA inhibitors that regulate several mechanisms involved in tumor growth, including mitochondrial metabolism, activation of oncogenic signaling pathways, and immune modulation. Population-based studies showed that statin intake may be negatively associated with RCC onset. The impact of statins on response to immunotherapy in mRCC is unknown. Herein we study the association between statin administration and outcomes in patients with mRCC treated with nivolumab in the NIVOREN-GETUG AFU 26 phase II trial (NCT03013335). Methods: Patients with mRCC who failed previous VEGFR inhibitors were included. We assessed nivolumab activity, including objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) according to statin intake at baseline. Toxicity was assessed using CTCAE v4.0. Results: Overall,133 patients were treated with statins at baseline among 702 evaluable for concomitant therapies (19%). Among them, median age was 68 (49-90), 84% were male, 85% had a performance status ≥ 80%, 42% were overweight and 20% obese. Patients treated with statins had mostly good (23%) or intermediate (58%) IMDC risk, 64% had grade 3 or 4 tumors, and nivolumab was given in a third line setting or more in 55%. Median follow-up was 23.9 months (95%CI 23.0-24.5) in the overall cohort. The ORR was 26% in patients treated with statins, PFS 5.0 months (CI95% 3.0 – 5.5), OS 27.9 months (CI95% 19.4-30.3). Outcomes of patients with or without statins did not differ significantly. Similar rates of grade 3-5 TRAE were reported in patients with (20%) or without (18%) statin intake. Conclusions: This is the first study to evaluate statin intake and outcomes with nivolumab in patients with mRCC. Despite numerically higher ORR, statins were not significantly associated with improved outcomes. These data require other analyzes considering other factors such as BMI and other comorbidities. Further studies may help better understand the interplay between immunity and metabolic reprogramming in RCC.

Purpose To evaluate the tolerability and effectiveness of uracil-tegafur (UFT) with leucovorin (LV) in the treatment of elderly patients with advanced colorectal cancer. Patients and Methods Patients ≥ 75 years of age with previously untreated colorectal cancer were eligible for this phase II, single-arm, open-label, multicenter cooperative group clinical trial. UFT 100 mg/m2 plus LV 30 mg orally every 8 hours for 28 days every 35 days was administered until progression. Results Fifty-eight patients were enrolled between June 2000 and July 2001, and 55 were treated. The median age of treated patients was 81 years (range, 75 to 90 years), 26 patients were (47%) women, and 80% had good performance status (0 to 1). The observed overall response rate was 22% (95% CI, 11.8% to 35.0%). The estimated median overall survival time was 13.0 months (95% CI, 9.6 to 17.4 months), and median progression-free survival time was 4.6 months (95% CI, 2.6 to 6.7 months). Among the 56 treated patients (including one ineligible patient), 31 (55%) experienced grade 3 to 4 toxicities, most commonly diarrhea (25%) and GI toxicity (36%), with patients older than 85 years of age at highest risk. Conclusion The results of this trial support the efficacy of oral UFT/LV in elderly patients with colorectal cancer. The regimen is tolerated moderately well overall, particularly as compared with other fluoropyrimidine regimens, although there is increased GI toxicity in the most elderly. These results suggest that studies using newer oral fluoropyrimidine analogs should be investigated in this patient population.
