4032 Background: Gemcitabine-platinum chemotherapy (CTx) regimens are widely accepted as first-line standard of care for patients (pts) with advanced biliary cancers (ABC). EGFR overexpression has been observed in ABC, suggesting that the combination with anti-EGFR monoclonal antibodies may be appropriate. Methods: Patients with ABC, WHO performance status (PS) 0-1, and without prior palliative CTx were eligible for this international, open-label, two-stage, non-comparative, randomized phase II trial. Patients received GEMOX (gemcitabine, 1 g/m² [10 mg/m²/min] at day [D]1 + oxaliplatin, 100 mg/m² at D2, arm A) or GEMOX + cetuximab (500 mg/m² at D1 or 2, arm B), every 2 weeks. The primary endpoint was crude 4-month progression-free survival (PFS) rate (H0, <40%; H1, ≥60%; planned sample size, 100 pts, increased to 150 pts by amendment to allow subgroup analyses). Secondary endpoints were objective response rate (ORR), disease control rate (DCR), PFS, overall survival (OS), and toxicity (NCI-CTC v3.0). Exploratory endpoints included early metabolic response as assessed by PET at 1 month, and tumor KRAS mutational analysis. Results: From Oct. 2007 to Dec. 2009, we enrolled 150 pts (median age, 62 years; male, 57%; metastatic, 79%; cholangiocarcinoma, 84%; median follow-up, 30 months) (Table). Conclusions: GEMOX-cetuximab regimen was well tolerated and met its primary endpoint (4-month PFS ≥60%). However, median PFS and OS were similar in both arms. Exploratory analyses (e.g., KRAS tumor status) are underway to identify pt subgroups deriving benefit from the addition of cetuximab to CTx. [Table: see text]

4566 Background: Docetaxel, in combination with cisplatin or oxaliplatin, has demonstrated efficacy against AGC. This randomized phase II trial evaluated two weekly docetaxel-based regimens to see which would be most promising according to objective response rate (ORR) as first-line therapy in AGC. Methods: Chemotherapy-naïve patients with measurable unresectable and/or metastatic gastric adenocarcinoma and a performance status ≤2 were randomly assigned to receive docetaxel (35 mg/m2) weekly on days 1 and 8 of a 21-day cycle plus either cisplatin (60 mg/m2 on day 1) (arm A) or oxaliplatin (120 mg/m2 on day 1) (arm B). Toxicity was assessed on days 1, 8, and 21 of each cycle, and response was evaluated every 2 cycles. Results: Between March 2007 and December 2008, 61 eligible patients entered. In Arm A, 29 patients were evaluable for objective response and 31 for safety. In Arm B, 28 patients were evaluable for objective response and 30 for safety. Median age was 52 years and disease status was comparable for both arms. Ten of 29 (34.5%) patients had a confirmed objective response in the arm A (95% confidence interval [CI] 17.1–51.8%) and 11 of 28 (39.2%) patients had a confirmed objective response in the arm B (95% CI 21.1- 57.2%). No significant difference was noted between the arms both for ORR (p=0.202) or for disease control (58.6% and 82.1%, respectively, p=0.082). Median progression free survival time was 4.4 month in the arm A and 4.3 months in the arm B (Hazard ratio = 0.936; 95% CI, 0.503–1.744; p = 0.836). There was no relevant difference in the occurrence of overall grade ¾ toxicity between the two arms (51.6% vs. 46.6%, respectively; p=0.800). Neutropenia was the most common grade 3/4 toxicity (32.3% vs. 36.6%, respectively). There was one treatment related death in Arm B. Conclusions: The preliminary results showed that both treatment arms have similar clinical efficacy as front-line treatment in AGC. Each regimen has a manageable tolerability profile. The accrual is ongoing. No significant financial relationships to disclose.

18021 Background and Methods: Outcome of patients (pts) with locally advanced NSCLC treated with radio- or chemoradiotherapy is poor. This two-stage phase II trial (planned sample size 46) aimed at evaluating feasibility and outcome of a tri-modality concept of neoadjuvant chemotherapy (CT), radiotherapy (RT) followed by definitive surgery in operable, stage IIIB NSCLC pts. Treatment consisted of 3 cycles of cisplatin (100 mg/m2) and docetaxel (85 mg/m2) followed by accelerated, concomitant boost RT (44 Gy/22 fx) and surgery. Primary endpoint is event-free survival at 1 year. Operable pts up to age 75 and a performance status of 0–1 with stage IIIB NSCLC (pleural effusion excluded) were eligible. Results: Forty-five eligible pts (46 accrued) with a median age was 60 years (range 28–70) were treated between September 2001 and May 2006. Tumor location was right-sided in 28 pts and left-sided in 17 pts. Histology was squamous cell 42%, large cell 11%, adeno-13% and undifferentiated carcinoma 33%. N3-disease was present in 29%, T4 stage in 78%. CT (45 pts) and RT (34 pts) were delivered as prescribed in >80% of cycles. The median time from enrollment to surgery was 3.7 months (2.8 - 5.2). The objective response rate after CT was 53% (95% c.i. 38–68%), after additional RT 67% (51–80%). Surgery (pneumonectomy in 17) was performed in 31 pts (69%), with an R0 resection in 24 pts. Median duration of hospitalization was 12 days (8–134). Two pts died in the perioperative phase due to ARDS and a cerebro-vascular event, respectively. Mature results of the primary endpoint and overall survival will be available at the ASCO meeting. Conclusions: Combined multimodality treatment strategy is feasible in a subgroup of patients, with acceptable toxicity. About two thirds of patients responded to the induction therapy, and were able to undergo subsequent surgery. No significant financial relationships to disclose.

Purpose The prognosis for women with recurrent and metastatic endometrial cancer is poor, and improved therapies are needed. The mammalian target of rapamycin (mTOR) pathway is an important target, and mTOR inhibitors show clinical activity in endometrial cancer. Patients and Methods An open-label, multicenter, randomized, phase II trial of oral ridaforolimus compared with progestin or investigator choice chemotherapy (comparator) was undertaken in women with metastatic or recurrent endometrial cancer who had progressive disease following one or two lines of chemotherapy and no hormonal therapy. The primary end point was progression-free survival (PFS) assessed by independent radiologic review. Results One hundred thirty patients were enrolled (64 received ridaforolimus and 66 received the comparator), and median age was 66 years. Treatment discontinuation as a result of adverse events was 33% with ridaforolimus versus 6% with the comparator, with common (> 10%) grade 3 toxicities being hyperglycemia, anemia, and diarrhea. Thirty-eight percent (ridaforolimus) versus 71% (comparator) of patients discontinued treatment as a result of disease progression. Median PFS at the protocol prespecified interim analysis with 58 PFS events (primary end point) was 3.6 months (95% CI, 2.7 to 7.3 months) for ridaforolimus and 1.9 months (95% CI, 1.9 to 2.3 months) for the comparator (hazard ratio, 0.53; 95% CI, 0.31 to 0.90; P = .008). PFS rate for ridaforolimus versus comparator was 48% versus 18% at 16 weeks and 38% versus 15% at 24 weeks. Objective response rate for ridaforolimus versus comparator was 0% versus 4% (P = .925), and stable disease was achieved in 35% versus 17% of patients (P = .021). Conclusion Oral ridaforolimus shows encouraging activity in advanced endometrial cancer but is associated with significant toxicity. Inhibition of the PI3K/Akt/mTOR pathway may be a viable therapeutic target.

10033 Background: First line imatinib has improved the outcome of patients (pts) with gastrointestinal stromal tumor (GIST), but primary and secondary resistance remain a problem. Dasatinib is a second generation tyrosine kinase inhibitor (TKI) and inhibits the activity of bcr-abl, src-family kinases along with a number of other oncogenic kinases including kit. In vitro, dasatinib has shown activity against imatinib-resistant cell lines. Routinely, pts diagnosed with GIST and treated with TKIs are monitored by computed tomography (CT). 18F-fluorodeoxyglucose positron-emission-tomography (FDG-PET) measures tumor metabolic activity for early response assessment, which might be of particular use in the clinical trial setting. Methods: This two-stage phase II trial investigated dasatinib in pts with TKI-naïve GIST. Dasatinib starting dose was 2x70mg/day in pts with histologically proven, FDG-PET positive GIST. Response evaluation was done by serial CT and FDG-PET using EORTC PET response criteria (Young et al. 1999). Elective surgery was allowed after 6 months of trial treatment. Primary endpoint was response (CR+PR) by FDG-PET after one month of dasatinib. Results: 47 of planned 52 pts have been enrolled from December 2007 to November 2011, when the trial was terminated due to slow accrual. 43 pts were eligible. Median age was 61 years, 24 pts were male, 19 female and 41 had a performance status of 0 or 1. At a median follow-up of 11.9 months, 20 pts were still on treatment. Pts went off trial for elective surgery (n=6), progression (n=11), toxicity (n=3), and three patients died (one on-drug). 5% of pts experienced G4, and 38% of pts G3 toxicity, which were most often gastrointestinal or pulmonary. 28% had their dose reduced or interrupted. The primary endpoint, FDG-PET response rate (CR+PR) at 4 weeks was 67% (13 CR, 16 PR, 7 SD, 3 PD, 4 not evaluable). Median progression-free survival is 11.1 months and median overall survival not yet reached. Conclusions: Dasatinib shows promising efficacy in TKI-naïve pts with FDG-PET positive GIST. Mutational data will be presented at the meeting.

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.
