LBA4032 Background: Currently, there is no standard regimen for palliative chemotherapy in metastatic, unresectable biliary tract cancer (BTC). A phase II trial of erlotinib monotherapy showed a promising anti-tumor activity in BTC with tolerable toxicity. Additionally, gemcitabine + erlotinib demonstrated superior efficacy when compared to gemcitabine alone in pancreatic cancer. Hence, we conducted a phase III trial to compare between GEMOX vs GEMOX+erlotinib (Tarceva [T]) (GEMOX/T) as first-line chemotherapy in unresectable, metastatic BTC. Methods: Eligible patients were as follows: histologically confirmed adenocarcinoma of biliary tract (CCC), ampulla of vater (AOV) or gall bladder (GB); unresectable or metastatic; ECOG performance status of 0~2; adequate marrow, hepatic, renal and cardiac functions; no prior chemotherapy. The primary endpoint was progression free survival (PFS). The study regimen was gemcitabine 1,000mg/m2, oxaliplatin 100mg/m2, erlotinib 100mg qd daily q 2 weeks. Results: From February 2009 to August 2010, 268 pts were randomized, 133 patients to GEMOX arm and 135 patients to GEMOX/T arm. Patient characteristics: median age 61 yrs (range 30-82); male (63.4%); CCC (n=180, 67.2%), GB (n=82, 30.6%), and AOV (n=6, 2.2%). With a median follow-up of 13.9 months (range, 6.7 – 25.0), median PFS was 5.8 months (95% CI, 4.6 - 7.0) in GEMOX/T arm and 4.2 months (95% CI, 2.7 - 5.7) in GEMOX arm (P=0.080). In subgroup analysis (CCC, n=180), however, median PFS was significantly longer in GEMOX/T arm (5.9 months) when compared with GEMOX arm (3.0 months, P=0.049). The overall response rate was significantly higher in the GEMOX/T arm when compared with GEMOX arm. There was no significant difference in overall survival between the two arms (GEMOX/T: 9.5 months, 95% CI, 7.6 – 11.4; GEMOX: 9.5 months, 95% CI, 7.5 – 11.5; P=0.611). The EGFR mutation testing results in correlation to responsiveness to erlotinib will be presented at the meeting. Conclusions: This phase III represents the first multicenter, randomized trial to compare GEMOX vs GEMOX/T in unresectable, metastatic BTC. Although PFS was not prolonged in GEMOX/T, there was a significant benefit in terms of PFS in GEMOX/T arm for CCC patients.

4092 Background: FOLFOX in combination with Bev is a standard regimen for treating advanced CRC. Cap on a d 1–14 schedule every 3 weeks is now being substituted for 5-flurouracil (CapOx); however optimal doses and schedules of Cap in combination with Ox and Bev needs continued evaluation. Intermittent weekly Cap (3,500 mg/m2, d 1–7) with Ox (85 mg/m2) every 2 weeks compared to the standard CapOx regimen in untreated advanced CRC has shown superior response and time-to-progression in Europe (Scheithauer W et al. J Clin Oncol. 21,1307; 2003). Methods: This phase II trial is designed to evaluate the A-ICOX regimen in US patients with CRC. The primary endpoint is to detect a 50% improvement in median progression free survival (PFS) from 8 to 12 months. With a sample of 40 patients, a 1-sided level 0.1 log-rank test has 81% power to detect this difference. Patients with advanced untreated CRC are eligible for study. Cap is administered at the dose of 2,500 mg/m2 in two divided doses on d 1–7 (n=11) and has been increased to 3000 mg/m2 dose (n=26), based on tolerability of the lower dose. The dose of Ox is 85 mg/m2 and Bev is 5 mg/kg. Cycles are repeated every 2 weeks. Results: Thirty-seven of 40 pts have been enrolled, with 30 evaluable for toxicity and response. Patient characteristics: Male (n=19); ECOG performance status 0 (n=18), 1 (n=12); median age 63 (range 38–80 years). Median cycles administered 4 (range 1–17). Partial responses were seen in 10 pts (33%), and metastasectomy was performed in 8 pts (27%). The PFS analysis is premature at this point. Gr 3/4 hematological toxicity occurred in only 2 pts (7 %). Other gr 3/4 adverse events have included: diarrhea (10 %), hand-foot syndrome (7 %), peripheral neuropathy (7%), nausea (7%) and vomiting (7 %). Conclusions: The first US experience of the A-ICOX regimen shows it to be very well tolerated, and Cap (3,000 mg/m2, d 1–7) in combination with Ox and Bev therapy can be safely administered. The incidence of subsequent metastasectomy, a marker of activity, is encouraging. A phase III trial of the A-ICOX regimen is now being conducted against standard Q-3 weekly CapOx/Bev.

Gemcitabine And Cisplatin

334 Background: Since 2010, the doublet gemcitabine and cisplatin has been standard first-line systemic treatment for non-resectable biliary tract cancer. In a phase I-II trial of the well-tolerated triplet of gemcitabine, oxaliplatin, and capecitabine, the median progression free survival (PFS) and overall survival (OS) were 6.9 and 12.5 months, respectively. Overall response rate was 34%. Since 2005 the regimen has been used in Denmark. We wanted to investigate the effectiveness of the triplet regimen given in daily clinic. Methods: We included 192 patients from two institutions. Patients had to have non-resectable biliary tract cancer and to be suitable for combination chemotherapy on doctor’s discretion. Gemcitabine 1000 mg/m2 and oxaliplatin 60 mg/m2 were given every two weeks followed by capecitabine 1000 mg/m2 b.i.d. for one week. At one institution the oxaliplatin dose was 50 mg/m2 and capecitabine dose 650 mg/m2 b.i.d. continuously. One cycle included two treatments and was typically administered for up to six cycles/months, but was allowed for longer time until progression. Results: At institution A, 117 patients were included and 73 (62%) were women. Median age was 66 years (range 25-80). Median treatment duration was six cycles/months (range 1-12). Thirty-five, 69, 12, and one patient(s) were in performance status 0, 1, 2, and 3, respectively. Ninety patients were evaluable for response and 6 (7%) had complete response, 18 (20%) partial response, 53 (59%) stable disease, and 13 (14%) progression as best response. Median PFS was 9.7 months (95% CI 8.5-11.7) and median OS 11.7 months (9.8-14.0). The results were comparable to institution B, where the response rate in 56 patients with measurable disease was 30%. In 75 patients evaluable for survival analysis, PFS was 8.1 months and OS 12.0 months for performance status 0-1 (n=55). Patients in performance status 2 (n=25) had a PFS and OS of only 1.7 and 2.8 months, respectively. Conclusions: A triplet of gemcitabine, oxaliplatin, and capecitabine given in daily clinic was well tolerated and has effectiveness comparable to results from a phase II trial and the pivotal phase III trial of gemcitabine and cisplatin.

4503 Background: There is no established standard chemotherapy for pts with inoperable ABC. We previously reported an improvement in progression-free survival (PFS) in a randomised phase II trial of 86 pts (ABC-01) using gemcitabine/cisplatin (GemCis) vs. gemcitabine (Gem) (Valle ASCO-GI 2006, abstr. 98). This study was extended into ABC-02, a phase III trial, to recruit a further 314 pts with overall survival (OS) as the primary end-point. Methods: Consenting pts with histologically/cytologically-confirmed ABC, aged ≥18 years, ECOG performance status 0 - 2, and adequate haematological, hepatic and renal function were randomised to receive either Cis (25 mg/m2) followed by Gem (1000 mg/m2 D1, 8 q21d) for 8 cycles, or Gem alone (1000 mg/m2 on D1, 8, 15 q28d) for 6 cycles, stratified by extent of disease, site of primary tumour, ECOG score and centre. The trial had an 80% power to detect an OS hazard ratio of 0.73. Results: From May 2005 to October 2008, 324 pts were randomised to ABC- 02 from 34 UK centres. We report the pre-planned combined analysis of ABC-01 and ABC-02 based on 410 pts (GemCis=206/Gem=204). Patient characteristics: median age 64 yrs (range 23–85); male (47%); metastatic disease (75%), locally advanced (25%); gallbladder (36%), bile duct (59%), ampulla (5%); and ECOG 0–1 (87%), 2 (12%). With a median follow-up of 6.1 months and 263 deaths, the median OS was greater with GemCis than Gem, 11.7 vs. 8.2 months (log rank p=0.002), with hazard ratio 0.68 (95%-CI 0.53, 0.86). The median PFS was greater with GemCis than Gem, 8.5 vs. 6.5 months (log rank p=0.003), with hazard ratio 0.70 (95%-CI 0.56, 0.88).Toxicity was similar between the arms (by week 12, 57% had a grade 3/4 toxicity in each arm), though there was a slight excess of neutropenia using GemCis. Conclusions: This is the largest ever study in ABC and demonstrates a clear survival advantage for GemCis without added clinically significant toxicity, setting a new international standard of care. No significant financial relationships to disclose.

417 Background: Gemcitabine plus platinum, notably cisplatin, is conceived as the standard regimen for advanced biliary tract cancer (ABTC) nowadays. Recent randomized phase II study (JCOG0805) showed that gemcitabine plus S-1 was more promising than S-1 alone in ABTC, and a randomized phase III, UMIN 000001685, is currently ongoing to compare the efficacy of gemcitabine plus either S-1 (GS) or cisplatin (GC) in ABTC. Herein, we report the results of a single arm phase II of modified GS in Taiwanese ABTC patients, NCT02425137. Methods: Patients with chemonaïve ABTC were eligible to receive 800mg/m2 gemcitabine with 10 mg/m2/min infusion, on day 1 plus daily 80/100/120 mg of S-1 (based on BSA) days 1-10, in a 2-week cycle. With Optimal Simon’s two-stage design and (p0= 0.4, p1= 0.6) for 12-week disease control rate (proportion of patients with complete or partial response [CR/PR] or stable disease ≥ 12 weeks [SD≥ 12weeks]) and given error probabilities (alpha = 0.05, beta = 0.2), the null hypothesis (p0) would be rejected if 24 or more patients with CR/PR/SD≥ 12weeks were observed among 46 accruals. Tumor response was assessed by CT/MRI every 6 weeks according to RECIST v1.1. Results: Between May 2015 and April 2016, totally 46 evaluable patients were enrolled to receive a median of 9.5 cycles (range: 3-31) of modified GS. After a median of 8.7 months (95% CI, 6.7-9.1) follow-up, 10 (21.7%) patients achieved PR and additional 23 (50%) had SD>12weeks. The median progression-free survival and overall survival was 5.6 (95% CI, 4.4-7.2) and 10.8 (95% CI, 7.6-not reached) months, respectively. All grade 3 treatment-related AEs were < 5%. The dose intensity of S-1 and gemcitabine were both more than 95%. Conclusions: By the observation of 33 patients with PR/SD≥ 12weeks, the null hypothesis was rejected. Modified GS is an active regimen with excellent safety profiles and deserves further investigation for the management of Asian ABTC patients. Clinical trial information: NCT 02425137.

5502 Background: Topotecan was evaluated in a novel combination regimen in comparison to standard therapy in front-line EOC. Methods: Women with newly diagnosed advanced EOC stages IIB-IV, ECOG performance status (PS) 0-1, age < 75, were randomized to either Arm 1: cycles 1 - 4: cisplatin 50 mg/m2 d1 plus topotecan 0.75 mg/m2 d1-5 IV; cycles 5 - 8: paclitaxel 175 mg/m2over 3 hrs d1 followed by carboplatin AUC5 day 1 or Arm 2: paclitaxel plus carboplatin as in Arm 1 for 8 cycles. The primary endpoint was progression free survival (PFS) and secondary endpoints included objective response, overall survival (OS), adverse event (AE) and Quality of Life (QoL). The sample size required 800 pts and 631 events to detect an improvement in PFS from 16 to 20 months (power 80%, 2-sided alpha 0.05). Results with 3.6 years median follow-up (MFU) were reported previously: there was no significant difference in PFS (Hoskins P, JNCI 2010). Final results including OS after MFU of 8.2 years are reported. Results: From 2001 to 2005, 819 pts (409 Arm 1, 410 Arm 2) were randomized. 704 PFS events and 605 deaths have occurred. PFS results are similar to first report: Median (months [mo]): 14.6 (Arm 1) and 16.2 (Arm 2), hazard ratio (HR) 1.03 (95% CI:0.81-1.30; p = 0.83). Median OS is 44.2 mo (Arm 1) and 44.8 mo (Arm 2), HR: 0.92 (95% CI:0.71-1.19; p=0.54). Baseline factors found to be independent predictors of OS in multivariate analysis are: a) pre-randomization surgery (debulking with no macro residual disease (MRD) to no debulking HR: 0.47; 95%CI:0.37-0.58; p < 0.0001; debulking with MRD (<1 cm) to no debulking HR: 0.76; 95%CI:0.61-0.94; p = 0.01), b) Stage (stage II to III or IV HR:0.52; 95%CI:0.36-0.76; p = 0.0007) and c) PS (0 vs 1 HR:0.76; 95%CI:0.63-0.91; p = 0.004). Post-treatment AEs were not significantly different in the two arms. Conclusions: OV16 final results confirm that sequential doublets of topotecan and cisplatin followed by carboplatin and paclitaxel offer no improvement in outcomes compared to carboplatin and paclitaxel. Pretreatment debulking, stage II and PS 0 are predictive of longer OS. Clinical trial information: NCT00028743.

4625 Background: Patients (Pts) with unresectable or metastatic biliary tract cancer (BTC) and gallbladder cancer (GBC) have a poor prognosis. Vascular endothelial growth factor (VEGF) expression has been detected in BTC and GBC. Increased angiogenesis has been correlated with advanced stage of disease and poor prognosis. Given reported activity of gemcitabine (GEM) and oxaliplatin (OX) in BTC/GBC and potential benefits of targeting the VEGF pathway with bevacizumab (B), we performed a study to examine the efficacy and tolerability of GEM, OX and B (GEMOX-B) in unresectable or metastatic BTC/GBC. Methods: Eligibility criteria included unresectable or metastatic measurable BTC/GBC, 0–1 prior chemotherapy regimens, performance status = 2, and adequate organ function. No clinically significant cardiovascular disease or history of active bleeding. Pts were treated with all 3 drugs intravenously on days 1 and 15 every 28 days (one cycle): B was given first at 10 mg/kg, followed by GEM at 1000 mg/m2 as dose rate infusion at 10 mg/m2/minute, and OX at 85 mg/m2. Whole body FDG-PET scan was obtained at baseline and after cycle 2. The primary endpoint of the study was progression-free survival (PFS). Results: 19 pts (10 BTC and 9 GBC) have been enrolled since May 17, 2006: median age = 69 (25–82), M/F = 13/6, ECOG 0/1/2 = 7/10/2. Treatment has been well tolerated with no grade 4–5 toxicities seen. Treatment related grade 3 toxicities included (number of pts): hypertension (2), neutropenia (1), transient SGPT elevation (1), proteinuria (1), neuropathy (1), and fatigue (1). Of 11 pts followed for at least 4 months, 3 had confirmed partial responses (PR), 5 had stable disease (SD) of at least 4 cycles, and 3 had progressive disease (PD) per RECIST criteria. Five pts had more than 50% decrease in CA19–9 levels. Of 16 PET studies analyzed, changes in SUV values from baseline to after 2 cycles of treatment were: 11 PRs, 4 SDs, 1 PD per EORTC criteria. Conclusions: GEMOX-B can be safely administered with tolerable safety profiles in patients with advanced BTC/GBC. Early evidence of antitumor activity was seen. A decreased SUV in FDG-PET following GEMOX-B treatment was observed in the majority of patients. No significant financial relationships to disclose.

The Impact

4601 Background: A phase I/II study with GV1001, a telomerase peptide vaccine, showed a median overall survival (OS) of 8.6 months in non-resectable PC (Bernhardt SL et al, Br J Cancer. 2006;95:1474–1482). This phase III trial was conducted to determine the impact on overall survival of G monotherapy vs. GV1001 in sequential combination with G in unresectable and metastatic PC. Methods: Eligible patients (pts) had chemotherapy-naive, advanced PC and ECOG performance status 0–1. Pts were randomized 1:1 to receive arm A: G (1,000 mg/m2 30 min i.v.) weekly for 7 weeks (w), 1w off and then 3w during 4-weekly cycles, or arm B: GV1001 0.56 mg s.c. plus GM-CSF as immune adjuvant on days 1, 3, 5, 8, 15, 22, 36, then every 4 weeks. Patients who progressed clinically or radiologically during GV1001 continued on GV1001 and concomitant gemcitabine. CT scans were performed every 8 weeks. The primary end-point was OS. A sample size of 520 patients allowed the detection of a hazard ratio (HR) of 0.73 (B/A), with 2α = 0.05 and 90% power. Results: Between June 2006 and May 2008, 365 pts were enrolled (A / B; 182 / 183). The study was stopped prematurely due to a preliminary analysis with 178 events showing no survival benefit of GV1001. Pts were well balanced for baseline characteristics: male 59.3% / 62.8%; median age 61y / 61y; ECOG PS 0 34.3% / 36.7%; locally advanced 22.4% / 20.7%. As of August 2008, 238 pts (A / B : 114 / 124) had died. Median OS was 7.3 / 5.9 months (HR 0.8; 95% CI 0.6–1.0). Median progression-free survival (PFS) was 3.7 / 1.9 months (HR 0.5; 95%CI 0.4–0.7). Grade 3–4 AEs: gastrointestinal 6% / 8%, infection 5% / 5%, vascular disorders 2% / 3%, neutropenia 6% / 3%. Conclusions: GV1001 did not show efficacy in sequential combination with G in advanced PC. The advantage of G monotherapy over the sequential combination may be due to the delayed treatment with G in arm B. [Table: see text]

7565 Background: Standard first-line chemotherapy for elderly NSCLC pts has been considered as a monotherapy with vinorelbine or gemcitabine globally. However, we have demonstrated the high efficacy of CP for elderly pts in our previous trial (Ann Oncol 2010). Meanwhile, D has been considered as an alternative option for this population in Japan according to the result of WJTOG9904 (JCO 2006). Thus we compared the two regimens to select the proper candidate for future phase III trial. Methods: Eligible pts were aged 70 years or older with newly diagnosed stage IIIB/IV NSCLC; ECOG performance status 0-1; adequate organ function; written informed consent. Pts were randomized to receive carboplatin (AUC 6) on day 1 and paclitaxel (70mg/m2 on day 1, 8, and 15) every 4 weeks or D (60mg/m2 on day 1) every 3 weeks. The primary endpoint was overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival, and toxicity profile. Assuming that ORR of 40% would be potential usefulness while ORR of 20% would be the lower limit of interest, 40 pts in each arm were required if expect 10% loss to follow up. Results: Between July 2006 and September 2010, 84 pts were enrolled and 41 pts in CP arm and 42 pts in D arm were eligible (median age, 76 years; 75% male; 72% stage IV). Median treatment cycle was 4 in each arm (CP, range 1-6; D, range 1-8). ORRs were 51% (95%CI: 36-66%) and 26% (95%CI: 12-39%) in the CP and D arm, respectively. With a median follow-up of 18.4 months, median PFS were 6.5 and 3.9 months in the CP and D arm, respectively (Logrank, P=0.0027). Grade 3 or severer toxicities were as follows: neutropenia (CP, 56% and D, 79%), anemia (CP, 15% and D, 7%), thrombocytopenia (CP, 10% and D, 0%), infection (CP, 20% and D, 25%). One treatment-related death due to neutropenia, pneumonia, and lethal arrhythmia occurred in D arm but none in CP arm. Conclusions: The platinum doublet CP achieved higher activity with an acceptable toxicity profile for elderly pts with advanced NSCLC compared to monotherapy with D. The superiority of CP to the monotherapy in this trial is consistent with results of recent IFCT-0501 trial (Lancet 2011).

LBA10008 Background: Oral multikinase inhibitor regorafenib (REG) demonstrated substantial activity in a phase II trial in pts with GIST after failure of both IM and SU (J Clin Oncol. 2011; 29:606s; abstr 10007). This phase III, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of REG for this unmet clinical need. Methods: Eligible pts had metastatic and/or unresectable GIST, objective failure of both prior IM and SU (progressive disease [PD] on, or intolerance to, IM and PD on SU), ≥1 measurable lesion, ECOG performance status 0 or 1. Pts were randomized 2:1 to receive best supportive care plus either REG 160 mg po once daily (3 wks on/1 wk off) or placebo (PL). The primary endpoint was progression-free survival (PFS) (modified RECIST 1.1, independent central review). Secondary endpoints included overall survival (OS), disease control rate (DCR, defined as rate of partial response [PR] plus stable disease [SD] lasting for ≥12 wks), response rate and duration, safety and correlative genotype analyses. At time of PD, pts were eligible for unblinding and crossover to open-label REG. Results: Between Jan and Aug of 2011, 234 pts were screened; 199 were randomized (REG: 133, PL: 66). Pts were stratified at randomization according to number of prior systemic therapies and geographical region. Baseline characteristics were balanced between the two arms. The primary endpoint was met: median PFS was 4.8 months for REG vs. 0.9 months for PL. Hazard ratio for PFS was 0.27 (95% CI, 0.18-0.39), p<0.0001. PFS rates at 3 and 6 months were 60% and 38% for REG vs. 11% and 0% for PL. DCR was 53% (REG) vs. 9% (PL).The HR for OS was 0.77 (p=0.20) with 85% PL pts having crossed over to REG. The most common > grade 3 treatment-emergent AEs in the REG arm during double-blind study were hypertension (28%), hand-foot skin reaction (21%), and diarrhea (8%). Conclusions: This randomized trial demonstrated that REG significantly improved PFS and DCR in pts with advanced GIST after failure of at least prior IM and SU. REG was well tolerated, with AEs as expected for this class and manageable with dose modifications.

9030 Background: Activating mutations of BRAF V600 can be found in 40%-50% of melanomas and are related to poor prognosis. In a phase 3 trial for the treatment of metastatic melanoma (MM) in chemotherapy-naive patients, nab-paclitaxel (nab-P) vs dacarbazine (DTIC) demonstrated a significant improvement in the primary endpoint of progression-free survival (PFS), assessed by independent radiological review (IRR), and a trend toward prolonged overall survival (OS) at the interim survival analysis. The study also explored the effect of BRAF status on the efficacy parameters. Methods: Chemotherapy-naive patients with stage IV melanoma (M1c stage 65%; elevated LDH 28%) and ECOG performance status 0-1 were randomized to nab-P 150 mg/m2 on days 1, 8, and 15 of a 28-day cycle (n = 264) or DTIC 1000 mg/m2 on day 1 of each 21-day cycle (n = 265) independent of BRAF status. Prespecified subgroup analyses of final PFS and interim OS in subgroups by BRAF status (V600E mutant, wild-type, or unknown) were performed. Results: BRAF mutation status was balanced between the treatment arms, with 36% and 38% of patients with known BRAF mutation status in the nab-P and DTIC arms, respectively. Patient characteristics were also balanced within BRAF subgroups. As shown in the Table, advantage in the nab-P arm vs DTIC arm was observed for both PFS and interim OS regardless of BRAFmutation status. Poststudy BRAF inhibitor treatment was also balanced. Conclusions: In this phase III trial, treatment effect was independent of BRAF mutation status, benefiting all patients who received nab-P vs DTIC. Therefore nab-P should be considered in the armamentarium for all chemotherapy-naive patients with MM. Clinical trial information: NCT00864253. [Table: see text]
