4095 Background: 5HIAA or CgA are biomarkers in some GEP NETs. We present posthoc analyses using prospectively collected urinary 5HIAA and serum CgA data from CLARINET. Methods: Adults with moderately or well differentiated, nonfunctioning (no symptoms of carcinoid syndrome), locally advanced or metastatic GEP NETs were randomized to LAN 120mg or placebo (PBO) every 4 weeks (wks) for 96 wks. Tumor response evaluated centrally (RECIST 1.0) and PFS were assessed by treatment. Biochemical response was defined as baseline > upper limit of normal (ULN, 41.6µmol/d 5HIAA; 98.1µg/L CgA) and ≥50% decrease from baseline to ≤ULN value on study. CgA analyses excluded gastrinoma patients (pts). Results: 48% (82/171) (45LAN; 37PBO) and 66% (129/195) (65LAN, 64PBO) of pts had > ULN baseline 5HIAA and CgA. In those pts with no radiologic progression, significantly greater reductions in 5HIAA (Table) and CgA were observed in LAN vs PBO pts at all assessments (all P< 0.05). PFS was significantly prolonged in LAN 5HIAA responders vs nonresponders (median not reached vs 22.1 months, P= 0.0076) but was not significantly different in PBO 5HIAA responders vs nonresponders. There were no significant differences in PFS by CgA response (responders vs nonresponders) in either LAN or PBO pts. Conclusions: These data suggest that serotonin is secreted by nonfunctioning tumors, but does not reach the threshold required for clinical carcinoid symptoms. Monitoring 5HIAA and CgA may be useful during LAN treatment of nonfunctional GEP NETs. Clinical trial information: NCT00353496. [Table: see text]

315 Background: In the groundbreaking, phase 3 RCT RADIANT-4 study, everolimus (EVE) significantly prolonged median progression-free survival (PFS) by 7.1 mo in patients (pts) with advanced, progressive, nonfunctional NET of GI or lung vs placebo (PBO); HR, 0.48 (95%CI, 0.35-0.67), P<0.00001 [Yao JC et al, ECC-ESMO, 2015]. Methods: InRADIANT-4, pts with advanced, progressive, well-differentiated (G1/G2), nonfunctional GI or lung NET were randomized (2:1) to EVE (10 mg/d) or PBO. In this analysis, pts with NET of GI tract (stomach, colon, rectum, appendix, caecum, ileum, duodenum, jejunum, or small intestine) and unknown primary were included. Results: Of 302 pts, 175 had GI NET (EVE [n=118], PBO [n=57]); 36 had NET of unknown primary (EVE [23], PBO [13]). In GI NET pts, median age was 63 y; females: 55%; G1/G2: 75%/25%; WHO PS: 0, 78% or 1, 22%; Caucasian: 73%. Similar baseline characteristics were observed in pts with NET of unknown primary. Ileum (41%), rectum (23%) and jejunum (13%) were the most common locations in GI subgroup. The table below lists prior treatments. In pts with GI NET, median PFS (95% CI) by central review (EVE vs PBO) was 13.1 (9.2-17.3) mo vs 5.4 (3.6-9.3) mo with an estimated 44% risk-reduction in favor of EVE (HR, 0.56; 95% CI, 0.37-0.84). In pts with NET of unknown primary, median PFS (95% CI) by central review (EVE vs PBO) was 13.6 (4.1-not evaluable) mo vs 7.5 (1.9-18.5) mo (HR, 0.60; 95% CI, 0.24-1.51). The most frequent G3/4 adverse events irrespective of drug-relationship reported in ≥5% pts in GI subgroup were diarrhea, hypertension, stomatitis, abdominal pain, fatigue, and acute renal failure. Conclusions: The present subgroup analysis of RADIANT-4 study demonstrated improvement in PFS with EVE for pts with GI NET, and suggests efficacy in NET of unknown primary, with an estimated 40% to 44% risk-reduction in favor of EVE vs PBO. Safety profile for EVE is consistent with that previously reported. Clinical trial information: NCT01524783. [Table: see text]

434 Background: In the CLARINET study, significant improvement in progression-free survival (primary endpoint) was reported in patients (pts) treated with lanreotide depot (LAN), a long-acting somatostatin analog, for moderately- or well-differentiated, nonfunctioning, locally advanced or metastatic GEP-NETs. A favorable safety profile was also observed. This retrospective analysis presents tumor response from CLARINET. Methods: Pts were randomized to LAN 120 mg (n=101) or PBO (n=103) once every 28 days for 96 weeks. Tumor response was evaluated centrally using RECIST version 1.0. Pts’ tumors were measured by sum of the longest diameter (SLD) of target lesions (TLs). Change was calculated for each pt’s SLD from baseline to last available post-baseline assessment. Tumor response was classified as complete response (CR): disappearance of all TLs and non-target lesions (NTLs) and no new lesions; partial response (PR): ≥30% decrease in SDL and no progressive disease (PD); stable disease (SD): not meeting criteria for CR/PR or PD; PD: ≥20% increase in SLD from baseline or nadir, unequivocal progression of NTLs or appearance of new lesions. The remaining pts were not evaluable (NE) for response. Results: 101 pts treated with LAN and 103 pts treated with PBO were assessed for tumor response. Among pts receiving LAN, 64% (65/101) demonstrated SD compared to 43% (44/103) of pts receiving PBO (Table). An additional 2 pts in the LAN group achieved a PR. Similar trends were observed in pts with pancreas and midgut origin tumors. Conclusions: A clinical benefit (defined as CR+PR+SD) of 66% (67/101) was observed with single agent LAN vs 43% (44/103) with PBO in the CLARINET population, further supporting the clinical efficacy of LAN.

Purpose Chemoradiation with cisplatin 100 mg/m2 given once every 3 weeks is the standard of care in locally advanced head and neck squamous cell cancer (LAHNSCC). Increasingly, low-dose once-a-week cisplatin is substituted because of perceived lower toxicity and convenience. However, there is no level 1 evidence of comparable efficacy to cisplatin once every 3 weeks. Patients and Methods In this phase III randomized trial, we assessed the noninferiority of cisplatin 30 mg/m2 given once a week compared with cisplatin 100 mg/m2 given once every 3 weeks, both administered concurrently with curative intent radiotherapy in patients with LAHNSCC. The primary end point was locoregional control (LRC); secondary end points included toxicity, compliance, response, progression-free survival, and overall survival. Results Between 2013 and 2017, we randomly assigned 300 patients, 150 to each arm. Two hundred seventy-nine patients (93%) received chemoradiotherapy in the adjuvant setting. At a median follow-up of 22 months, the estimated cumulative 2-year LRC rate was 58.5% in the once-a-week arm and 73.1% in the once-every-3-weeks arm, leading to an absolute difference of 14.6% (95% CI, 5.7% to 23.5%); P = .014; hazard ratio (HR), 1.76 (95% CI, 1.11 to 2.79). Acute toxicities of grade 3 or higher occurred in 71.6% of patients in the once-a-week arm and in 84.6% of patients in the once-every-3-weeks arm ( P = .006). Estimated median progression-free survival in the once-a-week arm was 17.7 months (95% CI, 0.42 to 35.05 months) and in the once-every-3-weeks arm, 28.6 months (95% CI, 15.90 to 41.30 months); HR, 1.24 (95% CI, 0.89 to 1.73); P = .21. Estimated median overall survival in the once-a-week arm was 39.5 months and was not reached in the once-every-3-weeks arm (HR, 1.14 [95% CI, 0.79 to 1.65]; P = .48). Conclusion Once-every-3-weeks cisplatin at 100 mg/m2 resulted in superior LRC, albeit with more toxicity, than did once-a-week cisplatin at 30 mg/m2, and should remain the preferred chemoradiotherapy regimen for LAHNSCC in the adjuvant setting.

Abstract Background Despite obvious advances over the last decades, locally advanced adenocarcinomas of the gastroesophageal junction (GEJ) still carry a dismal prognosis with overall 5-year survival rates of less than 50% even when using modern optimized treatment protocols such as perioperative chemotherapy based on the FLOT regimen or radiochemotherapy. Therefore the question remains whether neoadjuvant chemotherapy or neoadjuvant radiochemotherapy is eliciting the best results in patients with GEJ cancer. Hence, an adequately powered multicentre trial comparing both therapeutic strategies is clearly warranted. Methods The RACE trial is a an investigator initiated multicenter, prospective, randomized, stratified phase III clinical trial and seeks to investigate the role of preoperative induction chemotherapy (2 cycles of FLOT: 5-FU, leucovorin, oxaliplatin, docetaxel) with subsequent preoperative radiochemotherapy (oxaliplatin weekly, 5-FU plus concurrent fractioned radiotherapy to a dose of 45 Gy) compared to preoperative chemotherapy alone (4 cycles of FLOT), both followed by resection and postoperative completion of chemotherapy (4 cycles of FLOT), in the treatment of locally advanced, potentially resectable adenocarcinoma of the gastroesophageal junction. Patients with cT3–4, any N, M0 or cT2 N+, M0 adenocarcinoma of the GEJ are eligible for inclusion. The RACE trial aims to enrol 340 patients to be allocated to both treatment arms in a 1:1 ratio stratified by tumour site. The primary endpoint of the trial is progression-free survival assessed with follow-up of maximum 60 months. Secondary endpoints include overall survival, R0 resection rate, number of harvested lymph nodes, site of tumour relapse, perioperative morbidity and mortality, safety and toxicity and quality of life. Discussion The RACE trial compares induction chemotherapy with FLOT followed by preoperative oxaliplatin and 5-Fluorouracil-based chemoradiation versus preoperative chemotherapy with FLOT alone, both followed by surgery and postoperative completion of FLOT chemotherapy in the treatment of locally advanced, non-metastatic adenocarcinoma of the GEJ. The trial aims to show superiority of the combined chemotherapy/radiochemotherapy treatment, assessed by progression-free survival, over perioperative chemotherapy alone.

CRA9011 Background: In a phase II study, 13 (42%) of 31 patients with metastatic melanoma receiving high-dose (HD) IL-2 plus gp100:209–217(210M) peptide experienced objective responses (S.A. Rosenberg, et al, Nature Medicine 4: 321–327, 1998). Other studies showed a lower response rate (RR) but no randomized studies have been done. Methods: A prospective randomized phase III trial was conducted at 21 centers with 185 patients. Eligibility: stage IV or locally advanced stage III cutaneous melanoma, HLA A0201, no brain metastases, eligible for HD IL-2, and no previous HD IL-2 or gp100:209–217(210M). Arm 1 received HD IL-2 alone (720,000 IU/kg/dose) and Arm 2 gp100:209–217(210M) peptide + Montanide ISA followed by HD IL-2. The primary objective was clinical response. Secondary objectives were toxicity, disease free/progression free survival, immunologic response and quality of life. Central HLA typing, pathology review, and blinded response assessment were done at the NIH. Central data monitoring was done by The EMMES Corp. and a Data Safety Monitoring Board. Results: Numbers of patients enrolled, treated, and evaluable for response in Arm 1 were 94, 93, and 93 respectively; in Arm 2 91, 86, and 86. Toxicities were consistent with HD IL-2 ± vaccine. Investigator assessed RR showed significant improvement in overall RR for Arm 2=22.1% vs 9.7% (P=0.0223, Chi-Square) and progression free survival (PFS) in favor of Arm 2=2.9 months (1.7–4.5) vs 1.6 (1.5–1.8) (P=0.0101). Median overall survival favors Arm 2=17.6 months (11.8–26.6) vs 12.8 (8.7–16.3) (P=0.0964). Blinded response review is ongoing. Conclusions: RR and PFS were superior with peptide vaccine and HD IL-2 compared to HD IL-2 alone. This represents the first evidence of clinical benefit of vaccination in patients with melanoma.

3575 Background: The literature reports that adding biologics to chemotherapy (ctx) may increase the incidence of clinically significant neutropenia. his trial was conducted to evaluate the efficacy of PEG in reducing the incidence of febrile neutropenia (FN) in pts with locally-advanced (LA) or metastatic (m)CRC receiving first-line treatment with either FOLFOX/B or FOLFIRI/B. Methods: Key eligibility: ≥ 18 years old; measurable, nonresectable CRC per RECIST 1.1. Pts were randomly assigned 1:1 to either placebo or 6 mg PEG ~24 h after ctx/B. The study treatment period included four Q2W cycles, but pts could continue their assigned regimen until progression. Pts were stratified by region (North America vs rest of world), stage (LA vs mCRC), and ctx (FOLFOX vs FOLFIRI). Estimated sample size (N = 800) was based on the expected incidence of grade 3/4 FN (primary endpoint) across the first 4 cycles of ctx/B, powered for PEG superiority over placebo. Other endpoints included overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). Results: 845 pts were randomized (Nov 2009 to Jan 2012) and received study treatment; 783 pts completed 4 cycles of ctx/B. Median age was 61 years; 512 (61%) pts were male; 819 (97%) had mCRC; 414 (49%) received FOLFOX, and 431 (51%) received FOLFIRI. Grade 3/4 FN (first 4 cycles) for placebo vs PEG was 5.7% vs 2.4%; OR 0.41; p = 0.014. A similar incidence of other ≥ grade 3 adverse events was seen in both arms (28% placebo; 27% PEG). See table for additional results. Conclusions: PEG significantly reduced the incidence of grade 3/4 FN in this pt population receiving standard ctx/B for CRC. Follow-up is ongoing.

3538 Background: CRC liver metastases can be resected after downsizing with intensive chemotherapy schedules, with a strong correlation between the response and resection rates. Cetuximab plus chemotherapy has been shown to increase the rates of tumor response and resection of liver metastases. (Van Cutsem et al, JCO 2011). Methods: Patients (pts) with technically non-resectable and/or with > 4 liver metastases were randomized to treatment with FOLFOX/cetuximab (arm A) or FOLFIRI/cetuximab (arm B) and evaluated regarding resectability every 2 months. Resection was offered to all patients who became resectable during the study. K-ras and b-raf status were retrospectively evaluated. Data on tumor response and resection were reported earlier (Folprecht et al, Lancet Oncol 2010). Overall and progression free survival were analyzed in December 2012. Results: Between Dec 2004 and March 2008, 56 pts were randomized to arm A, 55 to arm B. For the current analysis, 109 pts were evaluable for overall survival (OS), and 106 patients for PFS. The median OS was 35.7 [95% CI: 27.2-44.2] months (arm A: 35.8 [28.1-43.6], arm B: 29.0 [16.0-41.9], HR 1.03 [0.66-1.61], p=0.9). The median PFS was 10.8 [9.3-12.2] months (Arm A: 11.2 [7.2-15.3], Arm B: 10.5 [8.9-12.2], HR 1.18 [0.79-1.74], p=0.4). Patients with R0 resection had a better OS (median: 53.9 [35.9-71.9] mo) than patients without R0 resection (27.3 [21.1-33.4] mo, p=0.002) and a better PFS (median 15.4 [11.4-19.5] and 8.9 [6.7-11.1] mo in R0 resected and not R0 resected pts, p<0.001). The 5 year survival in R0 resected patients is 46.2% [29.5-62.9%]. Conclusions: This study confirmed a favourable long term survival of patients with initially “nonresectable” CRC liver metastases treated in a multidisciplinary approach of neoadjuvant chemotherapy with cetuximab and subsequent metastasectomy in pts who became resectable. Clinical trial information: NCT00153998. [Table: see text]

9013 Background: Dabrafenib is a selective BRAF inhibitor with demonstrated efficacy in BRAF V600E-positive mutation in MM. The primary analysis of BREAK-3 (NCT01227889) compared progression-free survival (PFS) in patients (pts) with BRAF V600E-positive mutation MM treated with dabrafenib or DTIC. Methods: Median PFS for dabrafenib of 5.1 months (mo) and study methods were previously described (Hauschild A, et al. Lancet. 2012,380:358–365). Independent review ended at the primary analysis. PFS was updated in Jun 2012 at median follow-up of 10.5 mo for dabrafenib (67% of PFS events), and 9.9 mo for DTIC. Median overall survival (OS) was not reached, so another analysis of OS and safety was performed with data as of Dec 2012, at which time the median follow-up was 15.2 (dabrafenib) and 12.7 (DTIC) mo. PFS of subjects who crossed over was also evaluated at that time. Results: PFS hazard ratio was 0.37 [95% CI; 0.23, 0.57]; median PFS was 6.9 mo dabrafenib and 2.7 mo DTIC. In Dec 2012, 36/63 DTIC pts crossed over; median PFS was 4.3 [95% CI; 4.1, 6.1] mos. OS is presented in the Table.The four most common adverse events (AE) on the dabrafenib arm were hyperkeratosis (39%), headache (35%), arthralgia (35%), and pyrexia (32%). Serious AEs ≥ 5% on the dabrafenib arm included cutaneous squamous cell carcinoma/keratoacanthoma (10%) and pyrexia (5%). Conclusions: Longer follow-up confirms the benefits of dabrafenib on PFS and response rate. Median OS in the dabrafenib arm was over 18 mo and over 15 mo in the DTIC arm. OS results are confounded by crossover of DTIC pts to dabrafenib and likely by subsequent therapy after progression. The effects of subsequent therapy results will be investigated. The safety profile had no significant changes. Clinical trial information: NCT01227889. [Table: see text]

e19022 Background: Progression-free survival (PFS) is a key trial end point for clinical practice, as it relates to a change of treatment line. Grade 4 progression-free survival (G4PFS; defined as time from treatment start to the earlier of progressive disease [PD], onset of a G4 adverse event [AE], or death from any cause) is a composite end point incorporating a measure of tolerability to PFS. This post hoc analysis evaluates G4PFS and the effect of G4 AEs on PFS and overall survival (OS) in patients (pts) enrolled in PointBreak (PB) and AVAiL. Methods: Pts in PB were randomized to bevacizumab (BEV) 15 mg/kg q3w with carboplatin and paclitaxel (CP) or pemetrexed (CPem) for ≤4 cycles. Eligible pts received either BEV or BEV + Pem q3w until PD or unacceptable toxicity. Pts in AVAiL received cisplatin and gemcitabine for ≤6 cycles and either placebo or BEV (7.5 or 15 mg/kg) q3w until PD. AEs were graded via NCI-CTCAE v3.0. Kaplan-Meier and Cox model methods were used to estimate medians and hazard ratios (HRs) for PFS, G4PFS, and OS. PFS and OS were also compared in each arm for pts with occurrence of a G4 AE before week 12 of treatment vs those without. Results: Of those receiving BEV, ~30% of AVAiL pts and 38% of PB pts had a G4 AE. Uncomplicated neutropenia was the most common G4 AE in the CP + BEV arm of PB (26%) and in the BEV arms of AVAiL (11%). PFS, G4PFS, and outcomes by G4 AE occurrence are shown (Table). Conclusions: In both the PB and AVAiL trials, median G4PFS was numerically shorter than median PFS. G4 AE occurrence, however, did not affect subsequent PFS or OS in either trial. Clinical trial information: NCT00762034 and NCT00806923. [Table: see text]

10551 Background: The role of surgery in the management of patients with advanced gastrointestinal stromal tumors (GIST) in the era of imatinib mesylate (IM) remains unknown. We sought to assess the outcome of patients with locally advanced primary GIST tumors without metastases treated with IM in the neoadjuvant setting within the prospective BFR14 phase III trial. Methods: The data base of the BFR14 trial was searched for patients with locally advanced disease and no metastases. Patients with recurrent disease were excluded. Results: Twenty five patients (9 females, 16 males) met these criteria. Twenty patients were PS 0 or 1, primary tumor sites were: small intestine (n=7), peritoneum (n=7), rectum (n=4), stomach (n=4), esophagus (n=2), and pelvis (n=1). Nine of the 25 patients underwent surgical resection of the primary tumor after a median of 7.3 (range 3.4–12.1) months of treatment with IM. There was a significant improvement in progression-free survival (PFS) for patient who underwent surgical resection versus those who did not: median PFS: 28.7 month vs 12.9 months respectively (p=0.0463) this benefit did not however translate into a significant benefit in overall survival (OS), although the trend favoured the resected group: median OS median not reached vs 29.4 months (p=0.0677). Conclusions: Surgery may increase progression-free survival in patients with locally advanced GIST who become resectable following treatment with IM. [Table: see text]
