14105 Background: Cytotoxic chemotherapy has been widely used in patients (pts) with advanced or metastatic gastric cancer, but the reported high response rates in phase II settings have not been confirmed by randomized trials. Moreover, the therapeutic impact on survival has been modest. The purpose of this study was to evaluate Irofulven, a DNA interacting acylfulvene analog, as first line therapy for pts with recurrent or metastatic gastric cancer. Methods: The main eligibility criteria were: Histologically or cytologically confirmed disease; age > 18 yrs; ECOG ≤ 2; measurable disease; no prior chemotherapy for recurrent or metastatic disease; life expectancy > 3 months. Irofulven was given at 0.45 mg/kg i.v. over 30-min infusion (max. 50 mg), on Day 1 and 8, every 3 weeks. The primary endpoint was treatment response and toxicity; the secondary end-point was survival. A 2-stage phase II design was used. In the first stage, the target enrollment was 20, if ≤ 2 responses were observed, the study would be stopped and the treatment concluded to be ineffective; if ≥ 6 responses were observed, the study drug would be concluded to be active. Otherwise, another 15 pts would be entered into the second stage. Survival was constructed using the Kaplan-Meier method. All patients entering the trial were included in the survival analysis. Results: 23 pts were entered into the first stage. The median no. of cycles per pt was 2 (range: 1–6). 2 pts (9%) had ≥ 1 week delay in administration of subsequent cycle of chemotherapy. For the day 8 chemotherapy, 7 pts (30%) required dose reductions; 5 (22%) had dose omitted. 22% and 17% pts developed grade 3/4 anemia and neutropenia respectively. There was no grade 4 thrombocytopenia or neutropenic fever. Of the 20 evaluable pts, no responses was observed, 3 pts had stable disease after 2 cycles of treatment which was not confirmed by a further assessment. Median overall survival was 6.05 months (95% CI 4.55–9.39). Conclusions: Irofulven was tolerated at the described dose but showed no evidence of antitumor activity in patients with advanced gastric cancer.

4554 Background: Combination regimens of 3 drugs have shown promising activity as treatment for patients (pts) with metastatic gastric cancer (GC). Docetaxel combined with cisplatin and 5-FU (CF) improved overall survival and response rates when compared to standard CF. However, the identification of less toxic and more convenient variants of this regimen is still important. We have previously established a regimen with docetaxel (T) combined with oxaliplatin (E) and capecitabine (X) in a phase I trial [Grothe et al., Proc. ASCO 2006]. Results of a preplanned interim analysis of subsequent multicenter phase II trials of the TEX regimen are presented here. Methods: Pts with metastatic or locally advanced GC, adequate organ function, ECOG PS 0–2, and no prior chemotherapy for advanced disease (adjuvant allowed) were enrolled. TEX regimen was administered as defined: T 35 mg/m2 and E 70 mg/m2 on days (d) 1 and 8, with X 800 mg/m2 bid on d1–14 every 22 days Toxicity assessment was done 3-weekly while CT scans were repeated 9-weekly. Results: 35 of 48 pts were enrolled until 06/08: 28 male / 7 female, median age 59 (36–81) years, ECOG PS 0/1/2 69%/31%/0%, gastric / gastroesophageal cancer 60%/40%, distant metastases 96%, tumor in situ 37%. The most common toxicities reported were (CTC grade [gr] 3/4): diarrhea 20%/3%, vomiting 11%/3%, asthenia and neurotoxicity each 9%/0%. Mucositis and hand-foot-syndrome were observed in (grade 1+2 / grade 3) 29%/0% and 26%/3%, respectively. Hematoxicity was mild with grade 3 anemia in 10% and no other grade 3/4 toxicity except one episode of febrile neutropenia . Of 25 pts evaluable so far, first tumor response assessment revealed (RECIST criteria) partial response in 36% and stable disease in 40% of patients. Conclusions: TEX is a safe and tolerable regimen for patients with metastatic gastric cancer. Preliminary efficacy results indicate promising activity. Mature data including progression free survival will be presented at the meeting. [Table: see text]

14031 Background: Docetaxel (TXT) and S-1 are active agents against gastric cancer. A synergistic antitumor effect has been shown in a preclinical study (Takahashi et al., Oncology 2005), and our previous phase I trial demonstrated the safety and tolerability of the combination, and its potent activity. To prospectively evaluate toxicity and efficacy of S-1/ biweekly TXT, we conducted the current phase II study in patients with advanced and recurrent gastric cancer. Methods: Patients (pts) with advanced or recurrent gastric cancer, who have not received any chemotherapy except postoperative chemotherapy (not including S-1 or TXT), were eligible for the trial, and were treated with docetaxel 35 mg/m2 one hour iv infusion on day 1 and 15, and S-1 at a full dose of 80 mg/m2/day for two weeks every four weeks. Results: Thirty-five pts with measurable lesions (RECIST) (10 females, 25 males; performance status [PS] 0/1/2: 23/8/4, age 27–74, differentiated/undifferentiated adenocarcinoma: 19/16) have been enrolled. A total of 113 cycles were administered (median 3, range 1–6), and all pts were assessable for toxicity and efficacy. Grade 3–4 toxicities were: neutropenia in 20.0% (grade 4: 11.4%) of patients, leukocytopenia in 11.4% (grade 4: 0%), anemia in 5.7%, appetite loss in 8.6%, stomatitis in 8.6%, fever in 2.9%, and fatigue in 2.9%. All treatment related toxicities resolved, and no toxic death was reported. Thirteen partial responses (PR) were obtained, resulting in an overall response (OR) rate of 37.1% (95% CI: 0.22–0.55). Thirteen pts (37.5%) had stable disease, and 4 pts (12.5%) progressed. The tumor control rate was 74.3% (95% CI: 0.57–0.88). The median survival time (MST) and time to treatment failure (TTF) were 326 and 75 days, respectively. Conclusions: The combination of S-1/ biweekly TXT is active in advanced or recurrent gastric cancer, and can be given safely with proper management of adverse events even in outpatient clinic. S-1/ biweekly TXT is one of the most effective regimen to control metastatic gastric cancer with less toxicity. No significant financial relationships to disclose.

e15599 Background: The role of the second line chemotherapy in advanced gastric cancer was not clear, but possibility of prolongation of survival is open question. Irinotecan is promising agents in gastric cancer and this phase II study evaluated the efficacy and safety of combination chemotherapy with irinotecan, high dose of 5-fluorouracil (5-FU) and leucovorin in taxane and cisplatin based chemotherapy refractory metastatic gastric cancer. Methods: Eligible criteria were as followed; histologic confirmed adenocarcinoma of stomach, previously treated with taxane and cisplatin, age≥18, Eastern Clinical Oncology Group (ECOG) performance status of 1 or less, adequate organ function. Irinotecan (150 mg/m2) as a 30-min infusion and leucovorin (200 mg/m2) as a 15-min infusion were given on day 1, followed by 5-FU 400 mg/m2bolus infusion then 5-FU 2,400 mg/m2 as a 48-hour continuous infusion. This cycle was repeated every 2 weeks until disease progression or unacceptable toxicities. Results: Thirty-four patients were enrolled. The median age was 57 years (range 27–73 years), and the ECOG performance status of all patients was 1. All patients were evaluable for safety and survival and twenty seven patients (79.4%) were evaluable for tumor response. The overall response rate was 18.5% (95% CI: 3.9–33.1). The median progression free survival and overall survival were 4.6 (95% CI: 2.4–6.9) and 9.3 months (95% CI: 5.2–13.4), respectively. Greater than grade 3 haematological toxicities were neutropenia in nine (26.5%), febrile neutropenia in one (2.9%) and thrombocytopenia in one patient (2.9%). The major non-haematological toxicity was asthenia, but most of patients showed grade 1 or 2. Greater than grade 3 non- haematological toxicities were elevated AST/ALT in four (11.8%), hyperbilirubinemia in two (5.9%), nausea in two patients (5.9%). Conclusions: This results showed that the combination chemotherapy with irinotecan, 5-FU and leucovorin was well tolerated and active in taxane and cisplatin refractory patients.

14052 Background: To determine the activity and toxicities of low dose leucovorin (LV) plus fluorouracil (5-FU) regimen, combined with oxaliplatin every two weeks (modified FOLFOX-4), as a first-line therapy for patients with advanced or recurrent gastric cancer. Methods: Between January 2003 and March 2005, forty-five patients were enrolled in this study. Patients were treated with oxaliplatin 85 mg/m2 as a 2-hour infusion at day 1 plus LV 20 mg/m2 over 10 minutes, followed by 5-FU a 400 mg/m2 bolus and 22 hour continuous infusion of 600 mg/m2 5-FU at day 1–2. This treatment was repeated in 2 week intervals. Results: There was one patient (2.2%) demonstrated a complete response. Twenty patients (44.4%) showed a partial response. Overall response rate was 46.6%. Ten patients (22.2%) showed a stable disease and fourteen patients (31.1%) progressed during the course of the treatment. The median time to progression and overall survival time were 7.73 months (95% CI: 3.6–11.86 months) and 11.17 months (95% CI: 9.06–13.28 months) from the start of the chemotherapy, respectively. A total of 247 cycles were analyzed for toxicity. Major hematologic toxicities included grade 1–2 anemia (39.7%), neutropenia (30.4%), grade 3–4 neutropnenia (10.9%) and thrombocytopenia (9.3%).There were 12 cycles of neutropenic fever. The most common non-hematological toxicities were grade 2 nausea/vomiting (20%), grade 1–2 neuropathy (13.4%) and grade 3 diarrhea (2.2%). There was no treatment related death. Conclusions: The modified FOLFOX-4 regimen is safe and effective regimen as a first line therapy in advanced or metastatic gastric cancer. No significant financial relationships to disclose.

e19043 Background: Phase II and III studies have demonstrated that the EGFR-antibody, cetuximab (Erbitux), improves efficacy parameters when added to a platinum-based chemotherapy in the 1st-line treatment of patients with advanced NSCLC. This study assessed the efficacy and tolerability of cetuximab in combination with cisplatin and gemcitabine in this setting. Methods: Patients in this multicenter, single-arm, phase II Portuguese study received cetuximab (400 mg/m2 initial dose then 250 mg/m2 weekly) in combination with cisplatin (40 mg/m2) and gemcitabine (1,200 mg/m2) for 6 cycles (21 days). Main eligibility criteria included metastatic NSCLC of any histological subtype, ECOG PS 0/1, and measurable disease. Patients with brain metastases were excluded. The primary endpoint was the overall response rate (ORR) during treatment, according to RECIST criteria. Secondary endpoints included time to progression (TTP), overall survival, and adverse events. Statistical analyses were performed for the intention to treat (ITT) and per protocol populations. ORRs and the corresponding 95% confidence intervals (CIs) were estimated and Kaplan-Meier curves were computed for TTP. Results: A total of 48 patients were enrolled between December 2006 and March 2008. Seventy five percent of the patients were men and the median age was 62.5 years (range 34–75). Median TTP was 5.0 months (95% CI 3.9–6.1 months). Best ORR were 35.4% (95% CI 22.2–50.5%) and 38.1% (95% CI 23.6–54.4%) for the ITT and PP populations, respectively. No differences in response rates were observed when EGFR status (as determined by FISH and immunohistochemistry) was taken into consideration. Ninety-six grade III/V adverse events were reported; the most common were neutropenia and thrombocytopenia (36 and 18 events, respectively). Conclusions: Adding cetuximab to cisplatin and gemcitabine demonstrated high efficacy (ORR and TTP) with acceptable toxicities in a nonselected population of patients in 1st-line treatment of NSCLC.

Purpose In the randomized, multinational phase II/III trial (V325) of untreated advanced gastric cancer patients, the phase II part selected docetaxel, cisplatin, and fluorouracil (DCF) over docetaxel and cisplatin for comparison against cisplatin and fluorouracil (CF; reference regimen) in the phase III part. Patients and Methods Advanced gastric cancer patients were randomly assigned to docetaxel 75 mg/m2 and cisplatin 75 mg/m2 (day 1) plus fluorouracil 750 mg/m2/d (days 1 to 5) every 3 weeks or cisplatin 100 mg/m2 (day 1) plus fluorouracil 1,000 mg/m2/d (days 1 to 5) every 4 weeks. The primary end point was time-to-progression (TTP). Results In 445 randomly assigned and treated patients (DCF = 221; CF = 224), TTP was longer with DCF versus CF (32% risk reduction; log-rank P < .001). Overall survival was longer with DCF versus CF (23% risk reduction; log-rank P = .02). Two-year survival rate was 18% with DCF and 9% with CF. Overall response rate was higher with DCF (χ2 P = .01). Grade 3 to 4 treatment-related adverse events occurred in 69% (DCF) v 59% (CF) of patients. Frequent grade 3 to 4 toxicities for DCF v CF were: neutropenia (82% v 57%), stomatitis (21% v 27%), diarrhea (19% v 8%), lethargy (19% v 14%). Complicated neutropenia was more frequent with DCF than CF (29% v 12%). Conclusion Adding docetaxel to CF significantly improved TTP, survival, and response rate in gastric cancer patients, but resulted in some increase in toxicity. Incorporation of docetaxel, as in DCF or with other active drug(s), is a new therapy option for patients with untreated advanced gastric cancer.

4076 Background: Previous phase II study showed a high efficacy and safety of FOLFOXIRI (irinotecan, oxaliplatin, 5-fluorouracil, leucovorin) combination chemotherapy in metastatic colorectal cancer. This non-randomized open label phase II study evaluated the efficacy and safety of FOLFOXIRI in metastatic or recurrent gastric cancer patients. Methods: Patients with: histologically proven, bidimensionally measurable, metastatic gastric adenocarcinoma, age 18 - 70 years, with a performance status 0 - 2, no prior chemotherapy or at least 12 months after adjuvant therapy, life expectancy > 3 months, signed written informed consent were eligible. Treatment consisted of irinotecan 150 mg/m2 day 1, oxaliplatin 85 mg/m2 day 1, leucovorin 100 mg/m2 day and 5-fluorouracil 2000 mg/m2 as a 48-h continuous infusion starting on day 1, repeated every 2 weeks until unacceptable toxicity, patients’ refusal, or up to 12 cycles. The planned sample size was 48 and the primary endpoint was response rate. Results: From August 2004 to August 2005, 48 patients were prospectively enrolled. The median age was 54 years (24 - 69) and male:female ratio was 1.3:1. In total, 379 cycles were administered with a median of 9 cycles per patient (range, 1–12) and 45/48 patients were evaluable for treatment response. Three patients were not assessable for response due patients’ refusal for further chemotherapy following the first cycle. By per-protocol analysis, the objective response rate was 73.3 % (95% CI, 60.8–85.8) with 2 CRs and 31 PRs. Four patients (9%) had stable disease and 8 patients (18%) had progressive disease. The estimated median survival of all patients was 14.0 months (95% CI, 11.8 - 16.2 ) and the estimated median time-to-progression was 8.9 months (95% CI, 6.7–11.0). In total of 379 cycles administered, most common grade 3/4 toxicities were neutropenia (11% of all cycles) and emesis (12%). Grade 2 peripheral neuropathy occurred in 5 patients. One (2%) patient had severe tumor bleeding and 5 (10%) patients experienced grade 3 diarrhea. Conclusions: FOLFOXIRI combination chemotherapy showed a very promising preliminary anti-tumor activity and was generally well tolerated as a first-line treatment for patients with metastatic gastric cancer.
