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.

8028 Background: SCLC presents as ED-SCLC in 60%-70% of patients (pts). AMR, a synthetic anthracycline, is approved for these pts in Japan. We compare the efficacy and safety of single-agent AMR vs topotecan in non-Japanese pts with 2nd-line ED-SCLC sensitive to 1st-line platinum-based chemotherapy. Methods: This phase II, open-label, multicenter study enrolled pts with ED-SCLC sensitive to 1st-line platinum-based chemotherapy (recurrence or progression ≥90 days from 1st-line treatment). Pts aged ≥18 years with ECOG performance status (PS) ≤2 and only 1 prior therapy were eligible. Pts were randomized (2:1) to receive IV AMR 40 mg/m2/d (d, 1–3) or IV topotecan 1.5 mg/m2/d (d 1–5) and treated every 21 days until progression, unacceptable toxicity, or withdrawal. The primary endpoint, overall response rate (ORR, complete + partial response), used RECIST criteria. Secondary endpoints were progression-free survival (PFS), overall survival (OS), and safety. Results: In all, 76 pts were randomized to AMR (n=50) or topotecan (n=26) with AMR given for a median of 6 cycles (range 1–16) and topotecan 3 cycles (1–16). AMR significantly improved ORR rates vs topotecan (p<0.012; Table ). Median PFS/OS was 4.3 months (95% CI 2.0, 6.1)/9.3 months (95% CI 5.7, 12.0) with AMR vs 3.5 months (95% CI 2.1, 6.3)/8.9 months (95% CI 4.8, 13.8) with topotecan. There was a higher proportion of ECOG PS 2 pts in the AMR group (n=6) vs the topotecan group (n=2). A trend towards improved OS was observed in the ECOG 0–1 subgroup of 68 pts: median OS was 10.5 months with AMR vs 9.7 months with topotecan. The most common grade ≥3 adverse events with AMR vs topotecan were neutropenia (53% vs 74%), thrombocytopenia (31% vs 52%) and leukopenia (27% vs 30%). Three AMR pts (6%) and 1 topotecan pt (4%) died of neutropenic infection. Conclusions: AMR significantly improves ORR and has acceptable tolerability as 2nd-line treatment in pts with sensitive ED-SCLC. [Table: see text] [Table: see text]

ObjectivesWe conducted a phase II study to investigate the efficacy and toxicities of irinotecan plus oral S-1 in patients with advanced or recurrent uterine cervical cancer.MethodsPatients with advanced or recurrent cervical cancer previously treated with platinum based chemotherapy were enrolled. Irinotecan (150 mg/m2) was administered intravenously over the course of 90 min on day 1, and S-1 (80 mg/m2) was given orally in two divided doses from days 1 to 14 of a 21 day cycle. The primary endpoint of this phase II study was response rate. Secondary endpoints included safety, progression free survival, and overall survival.ResultsA total of 19 patients were enrolled and treated. The response rate was 29.4%. Grade 3–4 hematologic toxicities were observed in three patients (15.7%). The only grade 3–4 non-hematologic toxicity observed was grade 3 diarrhea. The median progression free survival and overall survival were 3 months and 9 months, respectively.ConclusionS-1 plus irinotecan in a 3 weekly setting is safe and active in women with advanced or recurrent cervical cancer previously treated with platinum based chemotherapy. Future corroborative clinical studies are warranted.

7718 Background: Gemcitabine and irinotecan has been shown to have an antitumor activity as a single agent against previously treated SCLC. The objective of this study was to assess the efficacy and safety of gemcitabine combined with irinotecan in patients with refractory or relapsed SCLC. Methods: Patients with histologically or cytologically confirmed SCLC, 20 to 74 years in age, performance status 0–2, with a history of receiving one platinum-based chemotherapy were eligible for the study. Treatment consisted of gemcitabine (1,000 mg/m2) and irinotecan (150 mg/m2) on days 1 and 15 of a 28-day cycle.The primary endpoint was the response rate (RR), and planned sample size for this phase II study was 30 patients (Simon's two-stage minimax design). Results: Thirty-one patients were enrolled and 30 patients (24 males/6 females, 10 refractory/20 sensitive, median age, 65 years) receive protocol treatment in this phase II trial. The median treatment cycles were 3 (1–10). The overall response rates was obtained in 39.3% (95% CI: 18.1% to 60.5%) of the patients, including two patients with refractory disease and 9 patients with sensitive disease. The median overall survival time was 14.4 months, and the 1-year survival rate was 51%. The median survival time of the patients with refractory disease was 7.4 months, compared with 14.4 months for patients with sensitive disease. The chief grade 3/4 toxicities included neutropenia (42%), thrombocytopenia (3%), diarrhea (9%), and liver dysfunction (3%). The only grade 4 toxicities were one case of grade 4 neutropenia (3.3%) and one case of grade 4 thrombocytopenia (3.3%). Conclusion: Gemcitabine plus irinotecan is an active regimen that seems to be well- tolerated by patients with previously treated SCLC. No significant financial relationships to disclose.

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]

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.

14040 Background: We are conducting a phase II trial of the proteasome inhibitor, PS-341, with or without irinotecan in pts with AGA. The combination of PS-341 and irinotecan has been studied in preclinical tumor models including a murine xenograft model of colon cancer, where the combination achieved significantly more tumor shrinkage than either agent alone. The primary objective of this study is to determine response rates, toxicities, progression-free survival, and overall survival in pts with AGA receiving PS-341 alone or in combination with irinotecan. Methods: All pts had gastric adenocarcinoma beyond the scope of surgical resection, measurable disease, and normal bone marrow, hepatic and renal function. All gave informed consent. In previously untreated patients, PS-341 was administered at 1.3 mg/m2 on days 1, 4, 8, and 11 as IV bolus every 21 days. Irinotecan was administered IV at 125 mg/m2 over 90 mins on days 1 and 8 every 21 days (Arm A). For previously treated patients, PS-341 was administered as a single agent at 1.3mg/m2 on days 1, 4, 8, 11 as an IV bolus every 21 days (Arm B). Radiologic evaluation and tumor measurements were performed every 8 weeks. Results: Thirty-seven pts have been enrolled; 29 are evaluable (4 never treated, 4 TETE). Twenty-two pts were treated in Arm A, and 11 in Arm B. All pts were eligible and the 29 treated pts were fully evaluable. Median age 58 (33–87); 26 males/7 females; median number of cycles received was 2.0. Most common toxicities: Grade 4 cardiac arrest (1), stomach perforation (1), leukopenia (2), diarrhea (1), edema (1); Grade 3 nausea (6), vomiting (7), diarrhea (4), febrile neutropenia (3), thrombocytopenia (6), anemia (6); Grade 5 death (3). Severe toxicities likely attributed to disease progression. Response rate was 33% for Arm A, 9% for Arm B. Progression-free survival was 1.8 mo. in Arm A, 1.4 mo. in Arm B. Median overall survival was 4.8 mo. in Arm A, 5.4 mo. in Arm B. Conclusions: The combination of PS-341 and irinotecan, a non-cisplatin containing therapy, is active in AGA and should be considered a key regimen. Monotherapy with PS-341 has a 9% response rate in this population of pre-treated patients with advanced disease. Accrual to this study is continuing. [Table: see text]

582 Background: LBH589 is a novel histone deacetylase inhibitor (HDACi) which induces apoptosis of tumor cells. LBH589 has been shown to cause regression of colon cancer in animal models and phase I trials have shown the agent to be well tolerated, providing rationale for studying this agent in pts with MCRC. Methods: This was a multicenter, open-label phase II study of single agent LBH589 in patients with MCRC who failed at least 2 prior regimens for metastatic disease. Measurable disease, adequate organ function and ECOG performance status of 0-2 were required. Pts received LBH589 30mg po on M/W/F until disease progression. Pts were evaluated for toxicity every 2 weeks and for response every 8 weeks. The primary endpoint was overall survival. Secondary endpoints included response rate, time to progression (TTP), and toxicity. Results: 29 pts were enrolled (16 male, 13 female). The median age was 59 (range 41-76). The median number of prior treatment regimes was 3 (2-11). The median survival was 5.1 months (range 1-24+). There were no objective responses. 3 pts had SD at 8 weeks. The median TTP was 7.7 weeks (range 1-38.). Six pts had grade 4 thrombocytopenia requiring platelet transfusion. Nine pts required dose reductions for toxicity. Conclusions: Single-agent LBH589 was not associated with objective tumor responses in this heavily pre-treated pt population. However, the median survival was comparable to that seen in other trials of single agent targeted therapy in the treatment of refractory MCRC. Thrombocytopenia was significant, and may complicate potential trials of combination therapy.

Poor Outcomes

4518 Background: Patients with BCVH have poor outcomes and data regarding the management of this heterogeneous group of patients is limited. Nivolumab and ipilimumab has demonstrated safety and efficacy in urothelial carcinoma and other malignancies. In this multicenter, single arm, multi-cohort phase II trial we evaluate the efficacy of nivolumab and ipilimumab in patients with BCVH and other advanced rare genitourinary cancers (NCT 03333616). Herein, we report the preliminary results of the fully accrued BCVH cohort. Methods: Eligible patients had metastatic BCVH, ECOG performance status of 0-2 and were either untreated or had received any number of lines of prior therapy excluding prior immunotherapy. Patients underwent a baseline biopsy and blood collection for correlative studies and received treatment with nivolumab 3 mg/kg and ipilimumab 1 mg/kg intravenously every 3 weeks for 4 cycles with continued maintenance of nivolumab 480 mg IV every 4 weeks. The primary endpoint was overall response rate (ORR) by RECIST 1.1. Results: 19 BCVH patients were enrolled at 4 institutions between 4/2018 and 1/2019: squamous cell (n = 6), small cell (n = 3), adenocarcinoma (n = 3), urachal (n = 5), plasmacytoid (n = 1), and spindle cell (n = 1). 13 (68%) patients had received prior systemic therapy including platinum-based chemotherapy in 92% patients. Median number of cycles of ipilimumab plus nivolumab received was 3 (range 1-8) and median follow-up was 3.6 (0.3-8.8) months. 13 patients had undergone at least one scan; ORR was 31% (4/13, 80%CI: 14-52%), with partial responses seen in small cell carcinoma (n = 2), urachal (n = 1) and a complete response in 1 patient with plasmacytoid carcinoma. 3 patients (16%) developed treatment-related grade 3 toxicities with 1 (5%) grade 4 toxicity. Conclusions: Nivolumab and ipilmumab resulted in objective responses in a subset of patients with BCVH with manageable toxicities. Updated clinical and correlative data will be presented. This combination may warrant further investigation in patients with BCVH, which has substantial unmet needs. Clinical trial information: NCT 03333616.

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.

Abstract Background Treatment options for malignant pleural mesothelioma (MPM) are limited. Anthracyclines are considered key drugs for treating MPM. However, their use is limited by severe cardiac toxicities. Amrubicin (AMR) is a next-generation anthracycline that is commonly used to treat lung cancer. We conducted a phase II trial of this drug in patients with previously treated MPM.Methods Eligible patients with MPM having adequate organ function and a performance status of 0–2 were enrolled after disease progression following pemetrexed/platinum therapy. Patients received 35 mg/m2 AMR on days 1–3 every 3 weeks until tumor progression or the appearance of unacceptable toxicities. The primary endpoint was the objective response rate (ORR). Median progression-free survival (PFS), overall survival (OS), number of treatment cycles, and adverse events (AEs) were evaluated as secondary endpoints.Results This trial was discontinued because of low accrual. From September 2013 to July 2018, five patients with MPM were enrolled. Stable disease (SD) was observed in three patients (60%), and progressive disease was noted in two patients (40%). The median PFS was 2.4 (range, 1.2–11.2) months, and the median OS was 9.1 (range, 6.2–22.0) months. The median number of treatment cycles was three (range, 2–11). Grade 1/2 toxicities were observed in all patients. Grade 3/4 neutropenia was observed in four patients (80%), but there were no cases of febrile neutropenia.Conclusion Despite the absence of the responders, the observation of SD in three patients suggests that AMR could have potential for treating MPM.Trial registration number and date of registrationUMIN000010739, May 16, 2013, retrospectively registered
