e19062 Background: Combination chemotherapy with carboplatin-docetaxel has been shown to be effective and safe for patients with locally advanced or metastasized NSCLC. The monoclonal anti-EGRF antibody cetuximab has the potential to improve response rates and survival without a substantial increase in toxicity when given in combination with chemotherapy. Methods: Open, non-controlled phase II study with a planned sample size of 70 pts. Pts with locally advanced or metastasized NSCLC, ECOG performance status ≤ 2 and no prior systemic chemotherapy were treated with carboplatin AUC5 (d 1) q4w for 4–6 cycles and docetaxel 35 mg/m2 (d1, 8, 15) q4w; cetuximab 400 / 250 mg/m2 (d 1) q1w until progression or intolerable toxicity (12 month max.). The primary endpoint was response rate defined as complete or partial remission according to RECIST. Secondary endpoints were toxicity, 1 year survival, median and progression free survival. Results: Subject of the interims analysis were 27 pts (25 stage IV, 2 stage IIIb). ECOG 0/1/2 was 33.3%/59.3%/3.7% (1 no data). 63% had prior surgery, 93% prior radiotherapy and all had adjuvant or inductive chemotherapy. Pts received a mean of 3 ± 1.4 cycles docetaxel-carboplatin-cetuximab. 49 adverse events were grade 1–2 and 12 grade 3–5. Skin toxicity (49%; 95%CI: 30%-68%; 41% G1/2, 8% G3/4), dyspnoea (35%; 95%CI: 17%-53%) and diarrhoea (23%; 95%CI: 7 %-39%; 19% G1/2, 4% G3) were most frequent. 11 pts (41%) had toxicity leading to dose reduction. 0 pts had complete and 11 pts had partial remission resulting in a response rate of 40.7% (95%CI: 22%-59%) based on intention to treat. 6 pts had stable disease (22.2%; 95%CI: 7%-38%). 5 pts were not evaluable for response. Conclusions: The combination of carboplatin-docetaxel-cetuximab has an overall acceptable tolerability. With a preliminary response rate of 40.7% the benefit risk assessment was found to be favourable and the study was continued. [Table: see text]

Significance Level

6076 Background: HCC is a rare subtype of follicular cell thyroid cancer that has been poorly studied in the past. Recent genomic studies have shown the PI3K/Akt/mTOR pathway is frequently altered in HCC. In addition, a phase II study of sorafenib (S) and everolimus (E) showed promising data in HCC. A study to evaluate this was initiated through Alliance and the International Thyroid Oncology Group. Methods: Patients (pts) were randomized to either sorafenib and everolimus (SE) vs. sorafenib alone (S). Inclusion criteria included; (1) diagnosis of HCC (confirmed through central review), no prior S or E, refractory to radioactive iodine, progressive disease by RECIST over prior 14 months. Primary endpoint was a comparison of progression-free survival (PFS) between SE and S using a stratified 1-sided log-rank test with 0.20 significance level and a power of 80%. 28 events were needed at final analysis. Secondary endpoints consisted of overall survival (OS), confirmed response rate (RR), and adverse events. Results: 35 pts were randomized from 10/2014 to 9/2019, 34 of which were evaluable for analysis (17-SE; 17-S) because 1 patient cancelled prior to receiving treatment. Median age was 66.5 years and 74% were male. ECOG performance status (PS) was 0 (47%) and PS 1 (53%). 41% had prior systemic treatment for HCC. No significant differences in baseline characteristics were observed between treatment arms. Median follow-up in 22 alive patients was 39.2 months (range: 15.1-64.9). Seven (21%) patients remain on treatment. PFS was significantly improved in the SE arm as compared to the S arm (HR=0.65 (95% CI: 0.26, 1.57); median PFS: SE=24.7 months (95% CI: 6.1-no upper), S=10.9 months (95% CI: 5.5-no upper); stratified 1-sided p=0.1662). OS was similar between the arms (2-sided p=0.4138). Confirmed response rate was similar between arms as well (SE: 18% (3 partial response (PR) vs. S: 24% (3 PR, 1 complete response)); Fisher’s exact p=1.00). Grade 3 adverse event (AE) rates (regardless of attribution) were similar between arms (SE: 77% vs. S: 77%; p=1.00). Each arm had 1 patient with at least one grade 4 AE (SE patient: cardiac arrest, tracheal obstruction, encephalopathy; S patient: mucositis oral) and no grade 5 AEs. Conclusions: PFS was improved with the addition of E to S in this small randomized multi-institutional phase II study done. Accrual was difficult, but these promising results suggest that this combination should be further studied.

Purpose This phase II study evaluated the activity of combined treatment with interferon alfa-2b and sorafenib, a Raf and multiple receptor tyrosine kinase inhibitor, in patients with advanced renal carcinoma. Patients and Methods Eligible patients had metastatic or unresectable renal carcinoma with a clear-cell component, no prior systemic therapy, performance status 0 to 1, and measurable disease. Treatment consisted of interferon alfa-2b 10 × 106 U subcutaneously three times weekly and sorafenib 400 mg orally bid. The primary end point was confirmed Response Evaluation Criteria in Solid Tumors response rate. Results Twelve (19%) of 62 assessable patients achieved an objective confirmed response. An additional 31 (50%) had an unconfirmed partial response or stable disease as best response. The median progression-free survival was 7 months (95% CI, 4 to 11 months). The most common adverse events were fatigue, anorexia, anemia, diarrhea, nausea, rigors/chills, leukopenia, fever, and transaminase elevation. Von Hippel-Lindau gene mutations were detected in four (22%) of 18 archival tumor specimens. Conclusion The confirmed response rate for the combination of sorafenib and interferon in advanced renal carcinoma is greater than expected with either interferon or sorafenib alone. The toxicity of this combination is dominated by adverse events common to interferon that limit further development of this regimen.

18070 Background: Although combined chemoradiotherapy is the standard of care in stage III NSCLC, the optimal chemotherapy regimen is not established. S-1, a fourth-generation oral fluoropyrimidine is an active new agent for NSCLC and the combination with cisplatin has a favorable toxicity profile. The objective of this study was to evaluate feasibility and efficacy of S plus P with concurrent radiation for unresectable stage III NSCLC. Methods: Patients with histologically or cytologically confirmed NSCLC, 20 to 75 years in age, performance status 0–1, with no prior chemotherapy were eligible for the study. Patients were treated with P (60 mg/m2 on day 1) and S (orally at 40 mg/m2/dose bid (80 mg/m2/d), on days 1 to 14) repeated every 3–4 weeks for 4 cycles and TRT (60 Gy/30 fr over 6 weeks starting on day 2). The primary endpoint was the response rate (RR), and planned sample size for this phase II study was 28 patients (Simon’s two-stage minimax design, P0=70%, P1=90%, a =0.1, β = 0.1). Results: Of 28 patients enrolled between August 2005 and October 2006, 28 were evaluable. There were 24 males and 4 females, median age of 63 (range 40–74) and 11 IIIA and 17 IIIB. Chemoradiotherapy was well tolerated; 2 cycles of SP and 60 Gy of TRT were administered in all patients and 24 (86%) patients received 4 cycles of SP. During concurrent chemoradiotherapy, grade 3 toxicities were neutropenia (8 pts), leukopenia (6 pts), fatigue (6 pts), anorexia (5 pts), febrile neutropenia (4 pts) and, esophagitis (4 pts). Only one grade 4 leukopenia were observed. During consolidation therapy, grade 3–4 neutropenia, anemia, esophagitis, and pneumonitis were developed in 4, 1, 1 and 2 patients, respectively. No toxic deaths have occurred. Overall RR was 85.7% (95% CI: 79.1- 98.7%) with 4 SDs and 24 PRs. The median progression-free survival and median survival is not mature enough to estimate as only 4 progression and no deaths have occurred. Conclusions: This chemoradiotherapy regimen produced promising response rate in patients with stage III NSCLC and it seems to be well-tolerated. No significant financial relationships to disclose.

18011 Background: Recurrent SCLC has a poor prognosis and is devoid of treatment options that improve overall survival. Irinotecan and paclitaxel are both active agents against SCLC, and have synergistic preclinical interactions. We conducted a phase II study to evaluate the efficacy and safety of the combination of irinotecan and paclitaxel for patients with recurrent SCLC. Methods: Patients with SCLC who relapsed following one prior chemotherapy regimen were eligible. Other pertinent inclusion criteria were: ECOG performance status 0–2, adequate bone marrow, hepatic and renal function and willingness to provide informed consent. Patients with untreated brain metastasis were excluded. Paclitaxel (75 mg/m2) and irinotecan (50 mg/m2) were administered on days 1 & 8 of every 3-week cycle. Treatment was continued until progression up to a maximum of 6 cycles or unacceptable toxicity. The primary endpoint was response rate. Toxicity was graded by CTC version 2.0. The simon two-stage design was utilized and the estimated sample size was 55 patients (stage I - 23 patients; stage 2 - 32 patients). The study has a 90% power to detect a response rate of 30%, with an alpha error rate of 10%. Results: 55 patients have been enrolled and complete data are available for 32 patients at the time of this report. Patient baseline characteristics are: male 53%, PS 0–44%; PS 1–47% and PS 2–6%. The median age is 61 years. Fifteen patients received ≥ 4 cycles. Salient grades 3–5 toxicities seen: neutropenia (13%), fatigue (13%); diarrhea (3%), hypersensitivity (3%) and hyponatremia (3%).The objective response rate is 37% (95% CI 19%-55%) with 9 PRs and 1 CR. Additional 8 patients (24%) had stable disease. The median survival is 19.6 weeks (95% CI 15.1–29.4) and the 1-year survival rate is 15%. Conclusions: The combination of irinotecan and paclitaxel is well tolerated and has promising anti-cancer activity in recurrent SCLC. Updated data on all 55 patients will be available at the time of the presentation. No significant financial relationships to disclose.

e19074 Background: S-1 is a novel oral 5-fluorouracil derivative that exhibits obvious activity against various tumor types including NSCLC. However, the effects of S-1 against SCLC have not been reported. The present phase II trial assesses the efficacy and safety of S-1 in previously treated SCLC patients. Methods: Eligible patients had pathologically documented SCLC that relapsed after platinum-based chemotherapy, ECOG performance status (PS) 0–2, and adequate bone marrow, kidney and liver function. Patients with untreated or symptomatic brain metastasis were excluded. Treatment comprised the oral administration of S-1 at 40 mg/m2 twice each day for 28 days every 6 weeks. The primary end point was the objective tumor response rate (RECIST). Secondary endpoints included progression-free survival and overall survival. Results: Twenty-six evaluable patients were enrolled (Simon's two-stage optimal design; α = 0.1; β = 0.1; P0 = 0.05; P1 = 0.25) with the following characteristics: male: female, 22/4; median age, 68 (33 - 79) y; PS0–1, n = 21; PS2, n = 5. The median number of prior treatment regimens was 2 (1–3). S-1 was administered for a mean of 1.3 cycles (1 - 5). One patient (3.8%) partially responded, 10 (38.5%) had stable and 15 (57.7%) had progressive disease. The overall response rate was 3.8% and the disease control rate was 42.3%. The median time to progression was 33 days. The median survival time was 8.0 months and the 1-year survival rate was 23%. This regimen was well tolerated. The common grade 3/4 toxicities included neutropenia (7.7%), leukopenia (7.7%), anemia (7.7%), hyponatremia (7.7%), rush (7.7%), infection (7.7%), and diarrhea (3.8%). None of the patients developed febrile neutropenia and no deaths were attributed to treatment. Conclusions: S-1 is well tolerated but has low activity as a single agent in previously treated patients with SCLC. No significant financial relationships to disclose.

e18005 Background: EOLE, a large cohort of 423 patients included in 1 year (July 2010 – July 2010) with locally advanced, metastatic or recurrent non-squamous NSCLC, aimed to describe the targeted population receiving first-line bevacizumab (Bev) in addition to chemotherapy with regards to progression-free survival, overall survival, safety and quality of life in real clinical practice. Methods: Patients who received physician’s choice of 1st-line Bev-containing treatment were included in this cohort study. Results: This analysis describes the inclusion data of 417 patients consisting of adenocarcinoma (92%), large cell carcinoma (4%), undifferentiated carcinoma in predominantly non-squamous (3%), bronchoalveolar carcinoma (1%). Patient characteristics were as follow: the median age being 60 (years) [32; 84], more males than females (68%), 40% had a baseline ECOG Performance Status (PS) 0, 47% of PS 1 and 12% of PS 2, most patients had Stage IV disease (91%), 13% of patients had never smoked. Tumor location was reported as central for 17% of patents and among them 4% was in contact with the large vessels. For 3% of the lesions a cavitation was notified; and 20% of included patients had brain metastases. The main comorbidities at the inclusion were: cardiovascular (45%), arterial thromboembolic and /or venous (20%) with pulmonary embolism (3%); related to the tumor lesion - bloody sputum (4%) and hemoptysis (1%). 68% of patients have received the dose of Bev 7.5mg/kg q3w; for 49% of patients Bev was combined with cisplatin/pemetrexed, 24% with carboplatin/paclitaxel, 13% with carboplatin/pemetrexed and 7% with cisplatin/gemcitabine. The EGFR mutation analysis was carried out for about 50% of patients. Conclusions: Compared to AVAil and SAil studies, EOLE cohort included more patients classified as having: a baseline PS of 2 (p <0.0001, Fisher test), a never smoked status (p<0.0001, chi2 test) and an adenocarcinoma (92%) (p<0.0001, chi2 test). Around a half of included patients received combination Bev - cisplatin /pemetrexed.

294 Background: Currently, there are no standard treatments for relapsed or refractory urothelial carcinoma (UC). Discouraging results have been observed in trials evaluating established chemotherapeutics as single agents or in combination regimens. Paclitaxel has moderate activity when used alone and in combination in UC. Pazopanib is active in other solid tumors secondary to its potent anti-angiogenic effects. We report the results of a multi-center phase II study evaluating the combination of paclitaxel with pazopanib in refractory UC. Methods: Eligible patients (pts) had histologically confirmed UC, with disease that progressed on upto 2 chemotherapeutic regimens. Pazopanib (800 mg) was administered daily, with weekly paclitaxel (80mg/m2) for 3 weeks in a 28 day cycle. Treatment was continued until disease progression or unacceptable toxicity. The primary endpoint of the study was response-rate (RR) based on RECISTv 1.1 criteria. Secondary endpoints included safety, and progression free-survival (PFS). Results: From April 2010 to September 2014, 32 patients were enrolled. Median age was 67 years (29-89) and median ECOG performance status was 1 (0-2). 17 pts (54%) had UC of the upper urinary tract disease and 15(47%) had primary bladder tumors. All pts had multiple metastatic sites, including 9 (28%) with liver metastases. Median number of prior cytotoxic regimens was 2, and 50% were considered cisplatin responsive. Objective responses were observed in 58% with 3 (12%) complete responses (CR), and 12 pts (46%) with partial responses (PR). Another 9 (35%) acheived stable disease (SD). High grade toxicities included grade 3 hypertension (n=2), grade 3 fatigue (n=4), grade 3 thrombosis (n=2) and grade 4 neutropenia (n=2). Nearly half of the patients( n= 14 ) required growth factor support. Conclusions: Our phase II study combining paclitaxel and pazopanib demonstratedsignificant anti-tumor activity in relapsed/refractory UC. This combination is safe, effective and is worthy of evaluation in randomized phase 3 study. Clinical trial information: NCT01108055.

124 Background: Docetaxel combined with cisplatin and 5-fluorouracil is active in advanced gastric cancer, but not generally accepted because of its substantial toxicities. We conducted a multicenter phase II study of triplet combination using paclitaxel, cisplatin and S-1 (PCS) as first-line treatment for advanced gastric cancer. Methods: Patients with previously untreated, locally advanced or metastatic measurable gastric cancer, a performance status < 2, age of 20-75 years, and adequate organ functions were given intravenous paclitaxel at 70 mg/m2 and cisplatin at 30 mg/m2 on days 1 and 15, plus oral S-1 at 40 mg/m2 b.i.d. on days 1 to 21, followed by 2-week rest, repeated every 5 weeks. Treatment was continued until disease progression or unacceptable toxicity occurred, or the patient refused the therapy. Study endpoints included overall response rate (ORR) as primary, progression free survival (PFS), overall survival (OS), and toxicity. Sample size of 40 patients was determined to reject the ORR of 55% under the expectation of 75% with a power of 80% and a one-sided α of 5%. Results: A total of 52 patients were enrolled in this study, among whom 49 were assessable for efficacy and 51 assessable for toxicity. ORR was 46.9% (95% CI: 32.5-61.7%). The median PFS and median OS were 5.4 months (95% CI: 4.1-7.0) and 11.5 months (95% CI: 7.3-16.1), respectively. Frequent grade 3/4 toxicities were neutropenia (51%), leucopenia (25%), anemia (20%), hyponatremia (16%), anorexia (14%), diarrhea (8%) and fatigue (8%). There was no treatment-related death. Conclusions: Triplet combination chemotherapy with PCS demonstrated superior feasibility with promising antitumor activity, though which did not meet the statistical hypothesis, for advanced gastric cancer.

650 Background: TAS-102 is a novel oral antitumor agent consisting of trifluorothymidine and thymidine phosphorylase inhibitor. In the TAS-102 phase II study, TAS-102 significantly improved overall survival (OS) compared with placebo (P) in pts with mCRC who had 2 or more prior regimens and refractory to fluoropyrimidine, irinotecan and oxaliplatin (A: 112pts; P: 57 pts; median OS, 9.0 vs 6.6 months (M); HR, 0.56; p = 0.0011) [K. Yamazaki et al. JSMO 2011 Abst 10428, Y. Kuboki et al. ECCO 2011 Abst 6005]. Km [Ann Oncol 2002; 13:308-317] suggested predictive prognosis marker and showed 4 parameters to classify pts with mCRC treated 5-FU-based first line chemotherapy into 3 risk groups (low risk group (L), intermediate risk group (IM) and high risk group (H)). We retrospectively evaluated TAS-102 phase II study by Km. Methods: Classification of pts into each risk group was done as follows: L is ECOG performance status (PS) 0-1, 1 tumor site; IM is (1) PS 0-1, >1 tumor site, ALP <300 IU/L and (2) PS >1, WBC <10×109 /L, 1 tumor site; H is (1) PS 0-1, >1 tumor site, ALP ≥300 IU/L, (2) PS >1, WBC <10×109 /L, >1 tumor site and (3) PS >1, WBC ≥10×109 /L. Progression-free survival (PFS) was assessed by an independent review committee. Results: Pts were classified as L/ IM/ H in 36/ 31/ 102 pts. The median OS for TAS-102 vs Placebo were in L (not reached vs 10.1M; hazard ratio (HR), 0.62), in IM (9.0 vs 4.9 M; HR, 0.44) and in H (7.6 vs 5.6 M; HR, 0.58). This risk stratified analysis by Km demonstrated that HR of OS and PFS was similar in each risk group (Table). Conclusions: The OS and PFS of TAS-102 were superior to that of placebo in all risk groups by Km. Further prospective TAS-102 phase III study is necessary to confirm these results. [Table: see text]

326 Background: Chemotherapy for penis cancer is used to palliate metastatic disease and treat locally-advanced disease. Pathologic similarities to head and neck SCC suggest that adding docetaxel (T) to platinum-based regimens may enhance efficacy. Methods: A single-stage single-arm phase II trial was conducted. Eligible patients had measurable, histologically proven penile SCC staged M1; or T4, any N, M0; or any T, N3/inoperable N2, M0; or any T, N1, M0 with Multi-Disciplinary Team agreement for chemotherapy as first-line therapy. Treatment was three 21-day cycles of TPF (day 1: T 75mg/m2, P 60mg/m2; days 1-5: F 750mg/m2/day). In 26 evaluable patients ≥14 responses were required to conclude a response rate of ≥60% (p0=0.35, p1=0.60, α=0.1, β=0.2; Fleming-A’Hern design). Primary endpoint was overall response rate at completion/discontinuation of trial treatment. Secondary endpoints included safety, tolerability, progression-free survival (PFS) and overall survival (OS). Results: 29 patients (median age 61 years) were recruited from 9 UK centres between Sept 2009 and Dec 2010. 8 patients were M1. 17 patients had performance status (PS) 0, 11 PS1, 1 PS2. 3 patients discontinued treatment early for reasons other than progression. Dose reductions/delays were reported for 13 patients. 28 patients have on-treatment toxicity data: 19 (68%) experienced grade 3/4 toxicity, with neutropenia most common (n=13, 46%). 7 patients (25%) experienced febrile neutropenia and/or neutropenic sepsis. 10/26 patients (38.5%, 95% CI: 20.2% - 59.4%) in the evaluable population responded. Twelve month PFS was 39.1% (95% CI: 20.9% - 56.8%; median PFS (all 29 patients/M1/M0): 7.1/ 3.1/ 9.6- months). Twelve month OS was 54.6% (34.9% - 70.6%; median OS (all patients/M1/M0): 13.7/ 6.9/ not reached yet-months). Conclusions: UK clinicians successfully recruited to a multi-centre trial in penis cancer, establishing a network of centres for future studies. Toxic effects of TPF were common but not unexpected. The trial did not reach its target response rate of ≥60% to justify further investigation although PFS and OS in this cohort compares favourably to reported data in literature.
