Docetaxel associated with oxaliplatin and 5-fluorouracil (FLOT) has been reported as the best perioperative treatment for gastric cancer. However, there is still some debate about the most appropriate number and timing of chemotherapy cycles. In this randomized multicenter phase II study, patients with resectable gastric cancer were staged through laparoscopy and peritoneal lavage cytology, and randomly assigned (1:1) to either four cycles of neoadjuvant chemotherapy (arm A) or two preoperative + two postoperative cycles of docetaxel, oxaliplatin, and capecitabine (DOC) chemotherapy (arm B). The primary endpoint was to assess the percentage of patients receiving all the planned preoperative or perioperative chemotherapeutic cycles. Ninety-one patients were enrolled between September 2010 and August 2016. The treatment was well tolerated in both arms. Thirty-three (71.7%) and 24 (53.3%) patients completed the planned cycles in arms A and B, respectively (p = 0.066), reporting an odds ratio for early interruption of treatment of 0.45 (95% confidence interval (CI): 0.18–1.07). Resection was curative in 39 (88.6%) arm A patients and 35 (83.3%) arm B patients. Five-year progression-free survival (PFS) was 51.2% (95% CI: 34.2–65.8) in arm A and 40.3% (95% CI: 28.9–55.2) in arm B (p = 0.300). Five-year survival was 58.5% (95% CI: 41.3–72.2) and 53.9% (95% CI: 35.5–69.3) (p = 0.883) in arms A and B, respectively. The planned treatment was more frequently completed and was more active, albeit not significantly, in the neoadjuvant arm than in the perioperative group.

124 Background: Docetaxel combined with cisplatin and 5-fluorouracil is active in advanced gastric cancer, but not generally accepted because of its substantial toxicities. We conducted a multicenter phase II study of triplet combination using paclitaxel, cisplatin and S-1 (PCS) as first-line treatment for advanced gastric cancer. Methods: Patients with previously untreated, locally advanced or metastatic measurable gastric cancer, a performance status < 2, age of 20-75 years, and adequate organ functions were given intravenous paclitaxel at 70 mg/m2 and cisplatin at 30 mg/m2 on days 1 and 15, plus oral S-1 at 40 mg/m2 b.i.d. on days 1 to 21, followed by 2-week rest, repeated every 5 weeks. Treatment was continued until disease progression or unacceptable toxicity occurred, or the patient refused the therapy. Study endpoints included overall response rate (ORR) as primary, progression free survival (PFS), overall survival (OS), and toxicity. Sample size of 40 patients was determined to reject the ORR of 55% under the expectation of 75% with a power of 80% and a one-sided α of 5%. Results: A total of 52 patients were enrolled in this study, among whom 49 were assessable for efficacy and 51 assessable for toxicity. ORR was 46.9% (95% CI: 32.5-61.7%). The median PFS and median OS were 5.4 months (95% CI: 4.1-7.0) and 11.5 months (95% CI: 7.3-16.1), respectively. Frequent grade 3/4 toxicities were neutropenia (51%), leucopenia (25%), anemia (20%), hyponatremia (16%), anorexia (14%), diarrhea (8%) and fatigue (8%). There was no treatment-related death. Conclusions: Triplet combination chemotherapy with PCS demonstrated superior feasibility with promising antitumor activity, though which did not meet the statistical hypothesis, for advanced gastric cancer.

6 Background: PEP02 is a novel nanoparticle liposome formulation of irinotecan (CPT-11). In phase I studies, PEP02 has improved pharmacokinetics (PK) of CPT-11 and its active metabolite-SN38 with encouraging safety and tumor response in several cancer types including gastric cancer. This study evaluated the efficacy and safety of PEP02 (P), irinotecan (I) or docetaxel (D) as a single agent in gastric or gastroesophageal junction (GEJ) adenocarcinoma. Methods: A randomized, 3 arms (1:1:1), Simon's 2-stage (2/21, 5/41 based on tumor response) study was conducted in Europe and Asia. Patients (pts) with locally advanced or metastatic disease, failed to one prior chemotherapy, ECOG PS ≤ 2, at least 1 measurable lesion, no prior CPT-11 or taxane, were treated with P - 120 mg/m2, I - 300 mg/m2, or D - 75 mg/m2 every 3 weeks. PK and pharmacogenetics (PGx) samples were collected for pts in P and I arms. Results: A total of 135 pts were randomized with 132 (44 per arm) treated between Jan 2008 and Jun 2010. Pts demographics (P/I/D): median age: 56/62/58, male (%): 79.5/77.3/77.3, Pts from Europe (%): 54.6/52.3/56.8, metastatic (%): 97.7/90.9/97.7, gastric adenocarcinoma (%): 84.1/79.6/68.2, and ECOG 0 + 1 (%): 93.2/93.2/90.9. The confirmed responders of P/I/D were 6 (13.6%)/3 (6.8%)/7 (15.9%) and disease control were 27 (61.4%)/27 (61.4%)/24 (54.6%). These three arms have similar progression free survival and overall survival. If stratified by region, Asian pts had longer survival than European pts. Toxicities of P/I/D were: grade 3/4 neutropenia (%): 9.1/13.6/15.9. grade 3/4 diarrhea (%): 27.3/18.2/2.3, hand-foot syndromes (%): 0.0/6.8/18.2. It was notable that symptoms related to acute cholinergic syndrome were less reported in P arm than in I arm. The PK data showed the mean T1/2, Cmax and AUC0→∞ of SN-38 in P/I arms were 88.8/22.8 hr, 8.79/44.1 ng/mL and 879/440 hr x ng/mL. Conclusions: This randomized phase II study suggests that PEP02 improves the PK profile and tumor response over irinotecan, and it is as efficacious as docetaxel in the 2nd-line treatment for gastric or GEJ adenocarcinoma. PEP02 is worthy of further evaluation as either 1st- or 2nd-line setting in future gastric cancer studies. [Table: see text]

4017 Background: FOLFIRINOX, consisting of leucovorin (LV), fluorouracil (FU), irinotecan (IRI) and oxaliplatin (L-OHP), and GnP, consisting of gemcitabine (GEM) plus nab-paclitaxel (nPTX), have shown superior efficacy over GEM in patients (pts) with metastatic pancreatic cancer. Although several studies have reported the efficacy of FOLFIRINOX or GnP for pts with locally advanced pancreatic cancer (LAPC), no randomized controlled trial to compare the two regimens has been conducted in those pts. To select the most promising chemotherapy for LAPC, a randomized phase II selection design trial (JCOG1407) was conducted to compare between modified FOLFIRINOX (FOLFIRINOX with dose reduction of IRI and without bolus FU; Arm A) and GnP (Arm B) for pts with LAPC. Methods: In Arm A, 85 mg/m2 of L-OHP, 200 mg/m2 of l-LV, 150 mg/m2 of IRI, followed by 2,400 mg/m2 of continuous FU over 46 hours are infused every 2 weeks. In Arm B, 125 mg/m2 of nPTX followed by 1,000 mg/m2 of GEM are infused on days 1, 8, and 15 every 4 weeks. The primary endpoint was overall survival (the proportion of 1-year OS), and secondary endpoints included progression-free survival (PFS), distant metastasis-free survival (MFS) and response rate in pts with target lesions. The planned sample size was 124 pts to select more effective regimen in 1-year OS with a probability of at least 0.85 and to test the null hypothesis of 53% in 1-year OS with a one-sided alpha of 5% and 80% Results: From 2015 to 2019, a total of 126 pts was enrolled from 29 Japanese institutions, and were allocated to Arm A (n = 62) or Arm B (n = 64). The median (range) age was 66 (44-75) years and 58.7% were male. At the analysis, after a median (range) follow-up of 1.52 (0.55-3.99) years, 75 (59.5%) pts died. The proportion of 1-year OS was better in Arm B, 77.4% [95% CI 64.9–86.0] vs. 82.5% [95% CI 70.7–89.9], but 2-year OS was better in Arm A, 48.2% [95% CI 33.3–61.7] vs. 39.7% [95% CI 28.6–52.5]. Median OS was 2.0 years [95% CI 1.6-2.7] in Arm A and 1.8 years [95% CI 1.5-2.0] in Arm B. 1-year PFS for Arm A/B was 47.5 % [95% CI 34.5-59.4]/40.2% [95% CI 27.8-52.3], and 1-year MFS was 64.2 % [95% CI 50.9-74.8]/57.3% [95% CI 43.9-68.6]. Arm A was better OS in pts with CA19-9 <1000 U/mL and the opposite trend was observed in pts with CA19-9>1000 U/mL. Response rate was 30.9% [95% CI 19.1-44.8] in Arm A, and 41.4% [95% CI 28.6-55.1]) in Arm B. Incidences of grade 3-4 non-hematological toxicities for Arm A and Arm B were 66.1% and 67.2%, respectively. There was no treatment-related death. Conclusions: This study was the first randomized trial comparing the two regimens. The 1-year OS of the primary endpoint in GnP was better than mFOLFIRINOX, but mFOLFIRINOX achieved longer survival in 2-year OS. It is required to confirm longer OS and safety profiles which regimen should be selected as a standard regimen in LAPC. Clinical trial information: jRCTs031180085.

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]

TPS4681 Background: Treatment of RCC has improved due to better understanding of its biology. New targeted therapies have improved time to progression and overall survival but the optimal sequencing of agents is unknown. Currently drugs are given sequentially, usually starting with sunitinib and often followed by an mTOR inhibitor or another VEGFR-targeted therapy, but resistance to both drugs eventually occurs probably due to host adaptive responses. We hypothesize that resistance might be delayed by planned alternation of treatments. Methods: EVERSUN is a single-arm, two-stage, multicenter, phase II clinical trial aiming to determine the activity and safety of an alternating regimen of two therapies with different targets (sunitinib and everolimus) in patients with advanced RCC. Key eligibility criteria: RCC with a clear cell component; metastatic or locally advanced disease not suitable for resection; ECOG performance status 0-1; low or intermediate MSKCC prognostic score. The primary endpoint is the status of being alive and progression-free (RECIST 1.1) 6 months after registration. Target accrual of 55 subjects gives 95% power and 95% confidence to distinguish between 6-month progression free survival rates of 64% or lower vs 84% or higher using a Simon 2-stage minimax design. The criteria for further evaluation come from the pivotal trial of single agent sunitinib as first line therapy for RCC, in which the 6-month progression free survival rate was 74%. Trial treatment is administered in 12-week (wk) cycles consisting of 4 wks of sunitinib (50 mg daily) followed by 2 wks rest, followed by 5 wks of everolimus (10 mg daily) followed by 1 wk rest. Disease progression is interpreted as failure of the most recent drug taken. Participants who stop one drug because of toxicity or disease progression, on or before the 6 month assessment, will continue the other drug until subsequent progression or prohibitive toxicity on the second drug. EVERSUN is an ANZUP Cancer Trials Group Ltd. trial coordinated by the NHMRC Clinical Trials Centre. Accrual commenced in September 2010 with 38/55 participants recruited as of the 31-Jan-12 from 17 Australian sites (ACTRN12609000643279).

729 Background: FOLFOX therapy, an infusion of 5-fluorouracil (5-FU) with leucovorin in combination with oxaliplatin (OXA), is a common first-line chemotherapy regimen for unresectable, advanced or recurrent colorectal carcinoma (CRC). However, long-term administration of OXA is associated with peripheral neuropathy (PN); decreasing treatment length of OXA may be beneficial without reducing its efficacy. Methods: Chemotherapy-naïve pts aged ≥20 yrs with RAS wild-type advanced/recurrent CRC were enrolled to receive 6 cycles of panitumumab (Pmab) + mFOLFOX6 once every 2 wks. Pts who completed 6 cycles of Pmab + mFOLFOX6 and confirmed no progressive disease were subsequently randomized 1:1 to continue to receive Pmab + mFOLFOX6 (arm 1) or Pmab + 5-FU/LV (arm 2). The primary endpoint was progression-free survival (PFS) rate at 9 mos after randomization. The threshold PFS rate was defined as 30%, and the expected rate was set at 50%, with a 90% power and a 1-sided alpha value of 0.10. In the primary analysis, a binomial test was conducted separately for each arm. This study was designed as a phase II randomized screening comparison study which does not use direct comparison for the primary analysis. Results: Of 164 enrolled pts who received initial Pmab + mFOLFOX6 treatment, 56 were randomized to arm 1 and 57 to arm 2. PFS rates at 9 mos after randomization were significantly higher than the defined threshold at 44.6% (80% CI, 36.4–53.2) in arm 1 and 47.4% (39.1–55.8) in arm 2. Median PFS after randomization was 9.1 (8.6–11.2) and 9.3 (6.0–13.0) mos, respectively. Grade ≥2 PNs occurred in 6 (10.7%) and 1 (1.8%) pts in arms 1 and 2, respectively. Serious AEs occurred in 14 (25.0%) pts in arm 1 and in 9 (16.7%) pts in arm 2. Conclusions: The results of this trial suggest that Pmab + 5-FU/LV after 6 fixed-cycles of Pmab + mFOLFOX6 may be a treatment option in pts with RAS wild type chemotherapy-naïve advanced/recurrent CRC. Pts treated with Pmab + 5-FU/LV had a lower occurrence of grade ≥2 PNs compared with Pmab + mFOLFOX6. Clinical trial information: NCT02337946.
