4538 Background: Patients (pts.) suffering from advanced gastric cancer have still a poor prognosis and treatment options are limited. In our previous phase II trial (AGMT-Gastric-1) we could show that the combination of oxaliplatin and irinotecan was well tolerated and showed an objective response rate of 58% (Anticancer Res 28:2901–2906, 2008). This chemotherapy regimen was tested in combination with cetuximab in a multicenter phase II trial. Methods: Oxaliplatin 85 mg/m2 biweekly and irinotecan 125 mg/m2 biweekly were combined with cetuximab 400 mg/m2 loading dose and subsequently weekly 250 mg/m2. 51 patients with histological proven unresectable and/or metastatic gastric adenocarcinoma were treated in a first line setting. Median age: 62 years (range 19–79 years), PS 0: 25 patients, PS 1+2 26 patients, single metastatic site: 24 patients, multiple metastases: 27 patients. Results: Frequently reported adverse events (more than 20% of pts.) were predominantly grade 1 or 2 and included neutropenia (35% of pts.), thrombocytopenia (33%), anemia (73%), nausea (45%), diarrhea (57%), alopecia (22%), and fatigue (37%). Grade 3 and 4 toxicities included neutropenia in 9/1 pts., thrombocytopenia in 1/0 pts., anemia in 3/1 pts., nausea in 2/0 pts., and diarrhea in 7/2 pts. Sensory neuropathy occurred mostly as grade 1 and 2 in 37% of pts., in 7 pts. grade 3 neurotoxicity was observed. Acneiform skin rash grade 1 / 2 / 3 / 4 was reported in 31% / 20% / 6% / 2% of pts. respectively. 16 pts. went off-study due to neutropenia (n=5), nausea/vomiting (n=1), diarrhea (n=1), progressive disease (n=3), toxic colon (n=2), and allergic reaction to cetuximab at first (n=2), second (n=1) or third infusion (n=1). 35 patients are assessable for response with 1 pt. (3%) showing a CR, 21 pts. (60%) a PR, 7 pts. (20%) a SD and PD in 6 pts. (17%). A disease control rate was achieved in 83%. Median time to progression was 24.8 weeks (n=29), median overall survival 38.1 weeks (n=32). Conclusions: The combination of oxaliplatin and irinotecan with cetuximab is feasible, safe and active in advanced gastric cancer. [Table: see text]

4074 Background: In our previous phase II trials (AGMT-Gastric-1 and AGMT Gastric-2) efficacy of oxaliplatin and irinotecan as well as oxaliplatin, irinotecan and cetuximab was shown. Time to progression however was short suggesting acquired chemotherapy resistance. Therefore sequential chemotherapy combined with bevacizumab is investigated in the presented trial. Methods: Oxaliplatin 85 mg/m2 biweekly (q2w) and irinotecan 125 mg/m2 q2w are administered for the first three months followed by docetaxel 50mg/m2 q2w for three months. Chemotherapy for 6 months is combined with bevacizumab 5 mg/kg q2w which is administered until progression. For this abstract 36 patients (pt.) with histologically proven unresectable and/or metastatic gastric adenocarcinoma have been evaluated in a first line setting. Median age: 62.5 years (range 26-80 years), PS 0: 25 patients, PS 1: 10 patients, missing: 1 patient, single metastatic site: 24 patients, multiple metastases: 10 patients, missing: 2. Results: Frequently reported adverse events (more than 20% of pt.) were predominantly grade 1 or 2 and included diarrhea (25/36, 69%), polyneuropathy (17/36, 47%), nausea (17/36, 47%), fatigue (15/36, 42%), neutropenia (13/36, 36%), abdominal pain (11/36, 31%), hypokalemia (9/36, 25%). Grade 3 and 4 toxicities included neutropenia (6/36, 17%), diarrhea (3/36, 8%), hypokalemia (3/36, 8%), anemia in (2/36, 6%), leucopenia (2/36, 6%), thrombocytopenia (1/36, 3%), nausea in (1/36, 3%). Objective response rate after 3 cycles was available in 25 patients: CR 1/25 (4%), PR 14/25 (56%), SD 8/25 (32%), PD 2/25 (8%). After 6 cycles there were 12 evaluable patients with CR 2/12 (16.7%), PR 5/12 (41.7%), SD 4/12 (33.3%) and PD 1/12 (8.3%). Conclusions: The combination of oxaliplatin and irinotecan with bevacizumab followed by docetaxel with bevacizumab is feasible and very active in advanced gastric cancer.

15052 Background: Taxane has been used widely in advanced gastric cancer, but toxicities are problematic. To avoid the bone marrow suppression, docetaxel could be replaced paclitaxel to reduce bone marrow suppression and to improve the efficacy, we planned to augmentation of the dose intensity. This phase II study evaluated the efficacy and safety of combination chemotherapy with paclitaxel, cisplatin, and 5-fluorouracil (5-FU) in advanced gastric cancer. Methods: Patients with histologically confirmed gastric adenocarcinoma, ECOG PS = 2, at least one measurable lesion and adequate organ functions were eligible. Paclitaxel (175 mg/m2) and cisplatin (75 mg/m2) were given as a 1-h intravenous infusion on day 1, followed by 5-FU (750 mg/m2) as a 24-h continuous infusion for 5 days. This cycle was repeated every 3 weeks. Results: Forty-five eligible patients (median age 56 years) were treated in this way. Of the 41 patients in whom efficacy was evaluable, an objective response rate (ORR) was seen in 20 (48.8%), a complete response in two, and a partial response in 18 patients. The median time to progression was 6.9 months (95% CI, 5.86–7.94), and the median overall survival was 13.1 months (95% CI, 8.83–17.37). The main hematological toxicity was neutropenia and greater than grade 3 neutropenia was observed in 67 cycles (25%). Febrile neutropenia developed in three patients (7.3%). The major non-hematological toxicities were asthenia and peripheral neuropathy, but grade 3 or 4 toxicity was not seen. Conclusions: The combination chemotherapy with paclitaxel, cisplatin, and 5-FU is a promising regimen, and was well tolerated in patients with advanced gastric cancer. No significant financial relationships to disclose.

4070 Background: There are only limited treatment options for advanced gastric cancer. Development of new treatment options is therefore warranted. The aim of this study was to evaluate the safety, feasibility and efficacy of an outpatient Oxaliplatin/Irinotecan combination in patients suffering from unresectable, locally advanced and/or metastatic gastric cancer. Methods: The combination of Oxaliplatin 85 mg/m2 biweekly with Irinotecan 125 mg/m2 biweekly was chosen since it has been shown in colorectal cancer that a biweekly dose of at least 85 mg/m2 oxaliplatin is superior to a lower dose and toxicity of Irinotecan is much lower if given fractionated into two doses. Furthermore the Irinotecan dose below MTD considers concerns about increased toxicity in gastric cancer patients. Results: 43 patients with histologically proven unresectable and/or metastatic gastric adenocarcinoma and no previous palliative chemotherapy and/or immunotherapy were selected. Median age: 61 years (range 32–81 years), male/female ratio: 24/19, PS 0:11 patients, PS <3:32 patients, locally advanced cancer 5 patients, single metastatic site: 19 patients, multiple metastases: 19 patients, previously adjuvant radiochemotherapy: 4 patients. This outpatient regimen was generally well tolerated. Frequently reported adverse events (more than 20% of patients) were grade 1 or 2 and included neutropenia (44% of patients), thrombocytopenia (30%), anemia (77%), nausea 67%), diarrhea (51%), alopecia (35%). Grade 3 and 4 toxicities included neutropenia in 2/43 pts., anemia in 3/43 pts., nausea in 2/43 pts., and diarrhea in 4/43pts. 5 patients were taken off-study due to toxicity (asthenia, nausea, reversible renal failure, diarrhea). Sensory neuropathy occurred only as grade 2 in 14%, no grade 3/4 neurotoxicity was observed. For response 38 patients are assessable with 3 pts. (8%) showing a CR, PR in 19 pts. (50%), SD in 11 pts. (29%), PD in 5 pts. (13%). Median TTP was 5.3 months and median OS 9.5 months. Conclusions: The outpatient combination of a biweekly Oxaliplatin/Irinotecan chemotherapy is well tolerated and shows a response rate within the range of other combination therapies. The favourable toxicity profile makes it an alternative 1st line regimen. [Table: see text]

Abstract Purpose The standard first-line treatment for human epidermal growth factor receptor type 2 (HER2)-positive advanced gastric cancer (AGC) is trastuzumab in combination with cisplatin and fluoropyrimidines. We evaluated the efficacy and safety of S-1 and oxaliplatin (100 mg/m2) (SOX100) combined with trastuzumab, a monoclonal antibody against HER2 for HER2-positive AGC.Methods In this single-arm, multicenter phase II study, patients with HER2-positive AGC received S-1 (80–120 mg per day) orally on days 1–14, oxaliplatin (100 mg/m2) intravenously on day 1, and trastuzumab (8 mg/kg on day 1 of the first cycle, followed by 6 mg/kg every 3 weeks) intravenously. The primary end point was 1-year survival rate. The secondary end points included overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and safety. Results A total of 25 patients from six centers were enrolled from December 2015 to March 2020. In the 25 patients evaluable for analysis, the 1-year survival rate was 70.8% [90% confidence interval (CI) = 55.5%–86.1%], whereas the median OS, PFS, and ORR were 17.8 (95% CI 10.5–22.9) months, 7.6 (95% CI 5.0–10.9) months, and 75.0 (95% CI 53.3–90.2) %, respectively. Major grade 3/4 adverse events included anorexia (20%), anemia (16%), peripheral sensory neuropathy (16%), and diarrhea (15%). Conclusion SOX100 combined with trastuzumab was effective with a favorable safety profile in patients with HER2-positive AGC.

90 Background: ABI-007 is a novel Cremophor-free nanoparticle albumin-bound paclitaxel. Cremophor-free formulation allows administration using a shorter infusion schedule (30 minutes) and without the need for premedicaion to prevent solvent-based hypersensitivity reactions.This single arm phase II study evaluated the efficacy and safety of ABI-007 given every three weeks to unresectable or recurrent gastric cancer patients (pts) who had received one prior chemotherapy regimen containing fluoropyrimidine and developed disease progression (PD) or recurrence. Methods: Eligibility include: histologically or cytologically confirmed gastric adenocarcinoma , received one prior regimen containing fluoropyrimidine analogs and developed PD or recurrence, age: 20 - 74, at least one measurable lesion by RECIST(1.0), PS:0-2, adequate organ function and written informed consent. Study duration was until PD or unacceptable toxicity developed. Pts received ABI-007 260 mg/m2, i.v. on day 1 of each 21 day cycle) without premedication. The primary endpoint was overall objective response rate (ORR). Results: From April 2008 to July 2010, total of 56 pts were enrolled, 55 received the study treatment, and 54 pts were evaluable for response. Median age was 64, Male/Female was 43/12, PS:0/1/2 was 33/22/0 and number of sites of metastasis corresponding was 1/2/≥3:19/21/15. ORR was 27.8% (15/54; 95%CI, 16.5-41.6) and DCR (disease control rate:CR+PR+SD) was 59.3% (32/54, 95%CI, 45.0-72.4) for all evaluable patients. One confirmed CR was observed. Median progression–free survival was 2.9 months (95%CI, 2.4-3.6), and median overall survival was 9.0 months (95%CI, 6.6-11.5). The most common grade 3/4 toxicities were neutropenia (49.1%), leucopenia (20.0%), lymphopenia (10.9%); and peripheral sensory neuropathy (23.6%). Conclusions: These data demonstrate that ABI-007 showed promising activity with well-tolerated toxicities for previously treated unresectable or recurrent gastric cancer pts.
