358 Background: BRCA1, BRCA2, and PALB2 germline mutations are associated with an increased risk of PC. Other BRCA-associated cancers have demonstrated increased sensitivity to PARP inhibitors (PARPi) and early trials have shown activity of PARPi in untreated BRCAmut PC. We evaluated theactivity of V in patients with previously treated BRCA/PALB2mutPC. Methods: Eligibility: BRCA1/2, or PALB2mutPC, at least 1 and up to 2 prior treatment regimens, measurable stage III/IVPC; ECOG 0-1. Treatment Plan: V 300mg BID (N= 3 pts), then V 400mg BID day1- 28. Primary endpoint: RECIST 1.1 response rate (RR). Statistical plan: Single-arm, non-randomized, open-label, phase II, two-stage design, unacceptable RR 10%, promising 28%, type I, II error rates 10%. Secondary endpoints: progression-free survival (PFS), duration of response, overall survival, safety, tolerability and archival tumor analyses. Results: Between 05/12 and 12/13, N= 16 enrolled. Male= 8, Female= 8. Median age= 52 years (range 43- 77). BRCA1 mut=5. BRCA2 mut=11. N= 1AJCC stage III PC, N= 15 AJCC stage IV PC. N= 8 and N= 8 (50%) had 1 and 2 prior lines of therapy respectively. N= 13 (81%) received prior platinum therapy. Response: N= 1 unconfirmed PR (PR at 4 months (mo), POD at 6 mo), N= 4 stable disease (SD), N= 10 progressive disease (PD); N= 1 inevaluable (12 days of V only due to disease-related complications). Median PFS was 52 days (range 12 to 423). Three pts treated at 400mg V were dose-reduced for toxicity. Six pts had V related grade 3 toxicity including fatigue (N=3), hematologic (N=2) and nausea (N=1). No therapy-related grade 4-5 toxicities were observed. Conclusions: V was well tolerated. While no confirmed partial responses were observed, single-agent activity of V in previously treated PC was noted, and N= 4 (25%) remained on study with SD for ≥ 4mo (4, 6, 6, 9 mo). A randomized phase II trial evaluating cisplatin,gemcitabine +/- V is underway in untreated BRCA/PALB2mutPC (NCT01585805). Results of correlative studies will be presented.

7707 Background: Systemic chemotherapy with cisplatin/pemetrexed is the approved first line treatment regimen for patients with MM. There is no approved second line therapy. In addition, many patients, especially those >70, cannot tolerate combination chemotherapy. Angiogenesis inhibitors have emerged as attractive potential therapies for MM and SU5416 and PTK787 have previously demonstrated single agent activity. We examined the efficacy of sorafenib, an inhibitor of VEGFR2 and PDGFR-b, in chemotherapy naïve and previously treated patients with MM. Methods: This was an open label single arm phase II study of sorafenib in chemotherapy naïve and previously pemetrexed treated patients with MM. Primary end point was response rate (RR). Secondary objectives were 3-month failure free and overall survival (FFS and OS). Forty-four (44) eligible patients were expected to enroll to differentiate a RR of <5% versus >20%, with a Type I error of 0.0675 and a power of 0.955 Results: Between 10/04 and 8/05, 51 patients were enrolled and treated with sorafenib 400 mg bid. One cycle was defined as 28 days; restaging occurred every 2 cycles. Baseline demographics: M/F (36/15); Median age (69; range 36–88; 45% >70); Histology (epithelial/sarcomatoid/mixed/unknown: 37/4/8/2); pleural/peritoneal MM (46/5); ECOG PS 0/1 (11/40); chemo-naive/prior chemo (20/31). Grade 3/4 toxicities occurring in >10% of patients: Fatigue (12 (25%); 11/1) and hand-foot reaction (6 (13%); 6/0). No study related deaths occurred. Estimates of RR and FFS are based on 47 patients with available follow-up data. Response: CR: 0; PR 2: 4% (95% CI; 1- 14%); SD 28 (60%); PD 11 (23%); unevaluable 6 (14%). Three month FFS was 78%; median FFS was 3.7 months and median OS was 10.7 months. The median FFS were 3.6 and 3.6 months and the median OS were 4.9 and 14.6 months in chemo naïve and previously treated patients, respectively. Conclusions: Sorafenib demonstrated modest activity in this phase II trial but did not meet its primary endpoint. The improved outcome in previously treated patients likely reflects patient selection. Ongoing correlative science studies including expression of p-ERK 1/2, baseline VEGF and PDGF levels, are being performed to help identify patient subsets who may benefit (PR or SD) from sorafenib.

7001 Background: Sunitinib malate (SU11248) is an oral, multitargeted tyrosine kinase inhibitor targeting VEGFR, PDGFR, KIT, FLT3 and RET on tumor cells, tumor neovasculature and pericytes. This is the initial report of an open-label, two-stage, multicenter phase II trial evaluating the single-agent activity of sunitinib in refractory NSCLC. Methods: Eligibility criteria included confirmed diagnosis of NSCLC, ECOG PS 0–1, no recent gross hemoptysis, no brain metastases, patients (pts) previously treated with 1–2 chemotherapy regimens, and adequate end-organ function. Pts received sunitinib at 50 mg/day po for 4 weeks (wks) followed by 2 wks off treatment (6 wks considered a cycle). Results: A total of 64 pts were enrolled and 63 pts treated, median age 61 yrs (range 33–87); adenocarcinoma (64%), squamous cell carcinoma (22%), other (14%); 66% male; PS 0:1, 45%:55%; median number of prior regimens: 2 (range 1–4); median time since the prior regimen: 2 months (range 1–21). To date, 63 pts have started cycle 1, 46 cycle 2, 22 cycle 3, 6 cycle 4 and 1 cycle 5. Grade 3–4 toxicities included fatigue/asthenia (21%), nausea (7%), vomiting (7%), abdominal pain (7%), and hypertension (5%). Most toxicities were grade 1–2 and included asthenia/fatigue (68%), anorexia (40%), dyspnea (37%), cough (35%), nausea (33%), mucositis (32%), dysgeusia (25%), diarrhea (21%), vomiting (19%), and constipation (19%). Grade 5 toxicities include pulmonary hemorrhage (n=2) and cerebral hemorrhage (n=1). Thus far, 6 confirmed partial responses have been observed among 63 treated pts (9.5%, 95% CI: 3.6–19.6%). Stable disease has been observed in an additional 12 pts (19.0%). Survival data are pending and will be presented. Conclusions: Sunitinib has provocative single-agent activity in previously treated pts with recurrent and advanced NSCLC, with the level of activity similar to currently approved agents. Sunitinib is well tolerated in this population. The trial is being extended to explore a continuous dosing strategy of sunitinib at 37.5 mg/day po. Based on these results, further trials are warranted and are ongoing with sunitinib in combination with standard agents/regimens. [Table: see text]

Abstract Tosedostat (TSD, CHR-2797) is an aminopeptidase inhibitor that selectively depletes amino acid pools in malignant cells, resulting in anti-proliferative, pro-apoptotic and antiangiogenic effects. In a phase I study, treatment with TSD resulted in complete remission in a number of refractory AML patients. The primary objective of this phase II study was to determine whether TSD was a sufficiently effective therapy to warrant pivotal studies. Methods. This was an open label, single agent, phase II study to assess clinical activity of TSD in elderly and/or previously treated patients with AML/MDS. Patients were treated with once daily oral doses of the maximum acceptable dose (130 mg) of TSD for up to 84 days. Further treatment was allowed if, in the opinion of the investigator, this was considered to be beneficial. Clinical responses were assessed by monthly bone marrow aspirates and weekly hematological assessments. Results. Of the 41 TSD-treated patients with AML (n=38) or MDS (n=3), who were enrolled between March and October 2007, 27 were male, 14 female, with a mean age of 67 years (range 34–82). The median performance status (ECOG) at baseline was 1 (range 0–2). Twelve (31.6%) AML patients and 2 (66.7%) MDS patients were chemotherapy naïve, and 9 (23.7%) AML patients had either secondary disease or adverse cytogenetics. For 16 (39%) patients, treatment with TSD was a second or later salvage attempt. Thirty two patients (30 AML, 2 MDS-RAEB1 and 2) received ≥28 days treatment, and 21 (51.2%) patients completed the formal 84-day study period (19 AML, 2 MDS). Nine (22%) of the patients (7 AML, 2 MDS) continued treatment with TSD after 84 days, and 6 (15%) patients were on TSD in total for more than 6 months (4 AML, 2 MDS). Ten (26.3%) of the AML patients responded to treatment; amongst these, 2 patients received TSD as 2nd/3rd salvage therapy, and a further 2 patients did not show a complete response (CR) after 2 previous induction courses of chemotherapy. Three AML patients achieved a CR (< 5% blasts in bone marrow), of whom 2 were in durable remission (232 days, continuing*; 171 days), and 7 had a partial response (PR, 5–15% blasts) lasting approximately 1–3 months. Two (66.7%) of the MDS patients also responded to treatment with TSD; these patients maintained stable disease for more than 6 months. All responders (CR, PR and SD) were >60 years at the time of the first dose. Median overall survival in AML patients was 130 days (range 8 – 478 days*). The most frequently reported adverse events were: fatigue (61%), thrombocytopenia (49%), pyrexia (39%), peripheral edema (39%) and diarrhea (34%); 9 (22%) patients withdrew due to drug related toxicity. TSD had no effect on hemoglobin or neutrophils. Conclusions. This study in patients with advanced AML/MDS with adverse prognosis demonstrates the anti-leukemic activity of TSD in elderly AML patients, as measured by CR and decreases in leukemic blasts. In addition, 2 relapsed high risk MDS patients achieved disease stabilization. TSD at 130mg qd is also very well tolerated over a long period of exposure (6–10 months). These results support further pivotal studies with TSD in elderly AML and MDS patients.

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.

7077 Background: TGFβ is a pleiotropic cytokine overexpressed by MPM. Based on preclinical data documenting a key role for TGFβ in promoting growth and progression of MPM, we are conducting a phase II trial of GC1008 in patients (pts) with progressive MPM. Methods: Pts with progressive MPM by modified RECIST criteria and PS 0-1 with 1-2 prior systemic therapies (at least 1 pemetrexed-based) are eligible. Treatment plan: GC1008 3mg/kg IV over 90 minutes every 21 days. Responses are assessed by modified RECIST every 6 weeks. The primary endpoint is progression-free survival (PFS) rate at 3 months; secondary objectives include safety with GC1008, response rate by modified RECIST, time to progression (TTP), and overall survival (OS). Results: The modified Gehan stage 1 stopping criterion of 1/13 pts with 3 month PFS has been exceeded. To date, 13 pts (10 PS 0; 3 PS 1) with MPM (median age 69; 2F, 11M; 11 epithelial, 1 sarcomatoid, 1 biphasic) enrolled. Treatment-related toxicities include G1/2 fatigue (3 pts), nausea (1 pt) and xerosis (1 pt). Other adverse events possibly related to GC1008 were rapid disease progression in 1 pt after 2 cycles, and G2 skin keratoacanthoma in 1 pt after 5 cycles. Three pts met the primary objective of 3 month PFS at 4.1, 4.2 and 9 months each. Stable disease (SD) was seen in 3 pts (23%). Median TTP is 1.4 months (95% CI 1.2-∞); median OS is 13 months (95% CI 6-∞). Increased serum mesothelin levels have closely tracked disease progression. Serum from 6/13 pts showed new antibodies against MPM tumor lysates as measured by immunoblotting. Two of 3 pts with SD had anti-tumor antibody responses. Mean baseline plasma level of TGFβ was 2447 pg/ml but did not correlate with baseline plasma TGFβ or TTP. Conclusions: GC1008 was well tolerated in pretreated MPM patients. SD occurred in 3 pts, all with prior disease progression. Evidence for humoral anti-tumor immunity was seen in nearly half of enrollees and in 2 of 3 pts with SD. OS compares favorably to prior single-agent studies in pretreated MPM.

438 Background: We hypothesized that alternating inhibitors of the VEGFR and mTOR pathways would delay the development of resistance in aRCC. Methods: Single-arm, two-stage, multicenter, phase II trial to determine the activity, feasibility, and safety of sunitinib 50mg daily 4 weeks (wk) on / 2wk off, alternating with everolimus 10mg daily for 5 wk on / 1 wk off. Participants had aRCC of MSKCC good or intermediate risk. Primary endpoint: proportion alive and free of progression at 6 months (PFS6m). Secondary endpoints included feasibility, tumour response, overall survival (OS), and adverse events (AE). Imaging was done every 6 wk till wk 24, then q12wk. Planned sample size of 55 allowed distinction between a PFS6m rate of ≤64% versus ≥84% with type 1 and type 2 error rates of 5%. Results: We recruited 55 eligible participants from Sept 2010 to Aug 2012: mean age 61, male 71%, good risk 16%, intermediate risk 84%. Feasibility: 80% could start cycle 2 within 14 weeks; 64% received ≥22 weeks of alternating therapy; 78% received ≥22 wks of any treatment. Efficacy: PFS6m was 29/55 (53%; 95% CI: 40%-66%). The OR rate was 7/55 (13%; 95% CI 4%-22%, all partial). After a median follow-up of 20 months, 47 of 55 had progressed with a median PFS of 8 months (95% CI: 5 to 10), and 30 of 55 had died with a median OS of 17 months (95% CI: 12 to undefined). Safety: AEs were consistent with those expected for each single agent. The most common grade 3 or 4 AE (number of participants) were hypertension (13), anaemia (9), oral mucositis (7), fatigue (n=7), GGT increase (n=6), pain (n=5), and platelet count decreased (n=5). Conclusions: The EVERSUN regimen was feasible and safe, but its activity did not meet prespecified values to warrant further research. This study supports the current approach of continuing first line anti-VEGF therapy until progression or prohibitive toxicity before switching to another drug. EVERSUN is an ANZUP Cancer Trials Group Ltd. trial coordinated by the NHMRC Clinical Trials Centre (ACTRN12609000643279). Clinical trial information: ACTRN12609000643279.

Background: In the PACIFIC study, progression-free survival (PFS) and overall survival (OS) of patients with unresectable, locally advanced, stage III non-small cell lung cancer (NSCLC) were prolonged by durvalumab as maintenance therapy after radical concurrent chemoradiotherapy using platinum-based antitumor agents. However, no data were obtained to reveal the efficacy of durvalumab after radiation monotherapy in patients unsuitable for chemoradiotherapy. Here, we describe an ongoing single-arm, prospective, open-label, multicenter phase II trial of durvalumab in patients with NSCLC ineligible for stage III chemoradiotherapy following radiation monotherapy (SPIRAL-RT study). Methods: Durvalumab at 10 mg/kg body weight is administered every 2 weeks after radiation therapy until individual patients meet the discontinuation criteria. The treatment duration is up to 12 months. The primary endpoint is the 1-year PFS rate. Secondary endpoints are response rate, PFS, OS, and safety. Durvalumab treatment after radiation monotherapy is expected to prolong 1-year PFS rate and have acceptable adverse events. Discussion: We are conducting an intervention study to investigate the safety and efficacy of durvalumab treatment in patients with NSCLC ineligible for stage III chemoradiotherapy following radiation monotherapy.
