Efficacy Analysis

4047 Background: PNET has long had few effective therapies other than chemotherapy. Recent placebo-controlled phase III trials of the mTOR inhibitor everolimus and the VEGF/ PDGF receptor inhibitor sunitinib noted improved progression-free survival (PFS). However, objective response rates (RR) with these agents are still <10%. Preclinical studies suggest enhanced anti-tumor effects with combined mTOR and VEGF targeted therapy. Methods: We conducted a phase II trial of the mTOR inhibitor TEM (25 mg IV q week) and the VEGF-A monoclonal antibody BEV (10 mg/kg IV q 2 weeks) in patients (pts) with well or moderately differentiated PNET and progressive disease by RECIST within 7 months of study entry. Co-primary endpoints were RR and 6-month PFS. Planned enrollment is 50 patients, with interim analysis for futility after the first 25 evaluable pts. Pts had no prior mTOR or VEGF targeted agents, ECOG PS 0-1, and adequate hematologic and organ function. Continued octreotide was allowed, but not required. Prior interferon, embolization, and ≤ 2 chemotherapy regimens were allowed. Results: Confirmed PR was documented in 13 of the first 25 (52%) evaluable patients. 21 of 25 (84%) patients were progression-free at 6 months. Both endpoints exceeded the protocol-defined criteria to continue enrollment. For 36 evaluable patients, the most common grade 3-4 adverse events attributed to therapy were hypertension (14%), leukopenia (11%), lymphopenia (11%), hyperglycemia (11%), mucositis (8%), hypokalemia (8%), and fatigue (8%). Conclusions: The combination of TEM/BEV has substantial activity in a multi-center phase II trial with RR of 52%, well in excess of single targeted agents in PNET. 6-month PFS was a notable 84% in a population of patients with RECIST criteria progression within 7 months of study entry. Accrual is ongoing.

Prior interferon, embolization, and ≤ 2 chemotherapy regimens were allowed. Results: 55 pts were eligible for response assessment. Confirmed PR was documented in 20 of 55 patients (37%). 44 of 55 (80%) patients were progression-free at 6 months. Of 49 pts evaluable for this endpoint, 12 month PFS is 49%. 15 patients remain on therapy. For evaluable patients, the most common grade 3-4 adverse events attributed to therapy were hypertension (18%), hyperglycemia (13%), fatigue (11%). leukopenia (9%), headache (9%), proteinuria (7%), and hypokalemia (7%). Conclusions: The combination of TEM/BEV has substantial activity in a multi-center phase II trial with RR of 37%, well in excess of single targeted agents in PNET. 6-month PFS was a notable 80% in a population of patients with RECIST criteria progression within 7 months of study entry. Phase III trials of combined VEGF/mTOR inhibition in PNET should be pursued. Clinical trial information: NCT01010126.

4139 Background: Nearly all stage IV pancreatic adenocarcinoma (PAC) patients progress after first-line treatment, and second-line options are limited. SGT-53 is an investigational product for tumor-targeted TP53 gene therapy that has completed phase Ia/Ib trials [Senser et al (2013), Mol Ther 21:1096; Pirollo et al (2016) Mol Ther 24:1697]. Methods: Here we provide an interim analysis of a Phase II trial (SGT53-02-1; NCT02340117) combining SGT-53 with gemcitabine/nab-paclitaxel (GEM/ABX). Eligible were first-line patients or those who had progressed after FOLFIRINOX (FFX) and/or gemcitabine-based therapy (second-line). In a 7-week treatment cycle, SGT-53 (3.6 mg DNA) was given once or twice weekly with GEM/ABX (1000 mg/m2/wk and 125 mg/m2/wk, respectively, for 3 of 4 weeks). Progression-free survival (PFS) and objective response rate (ORR) are primary endpoints.Overall survival (OS) and PFS are estimated by Kaplan-Meier analysis. Results: Of all evaluable patients (n=20), best response in 7 patients was determined to be partial response (PR) and 13 had stable disease (SD); none had progressive disease. In the second-line patients (n=11) there were 5 PR and 6 SD after 9 had failed FFX treatment, 3 had failed gemcitabine-based treatment and 1 had failed both. For patients with elevated CA19-9, SGT-53 + GEM/ABX resulted in marked reductions in the tumor marker. Published data for patients with PAC after therapy failure [Mita et al (2019) J Clin Med 8: 761; Portal et al (2015) Br J Cancer 113:989; Wang-Gillam et al (2016) Lancet 387:545] are shown for comparison. Notably, mPFS in our second-line patients was 7.4 months versus 3.1 months for the approved second-line therapy [Wang-Gillam et al (2016)]. This improvement in PFS exceeds the benchmark proposed to predict a clinically meaningful Phase III trial [Rahib et al (2016) Lancet Oncol 2:1209]. Conclusions: Our data suggest a clinically meaningful benefit of adding SGT-53 to GEM/ABX particularly for second-line PAC patients, most of whom had failed prior FFX treatment. Clinical trial information: NCT02340117. [Table: see text]

Purpose To determine the efficacy and safety of a biweekly regimen of leucovorin (LV) plus fluorouracil (FU) alone or in combination with cisplatin or irinotecan in patients with previously untreated metastatic gastric adenocarcinoma and to select the best arm for a phase III study. Patients and Methods One hundred thirty-six patients (two were ineligible) were enrolled onto the randomized multicenter phase II trial. Patients received LV 200 mg/m2 (2-hour infusion) followed by FU 400 mg/m2 (bolus) and FU 600 mg/m2 (22-hour continuous infusion) on days 1 and 2 every 14 days (LV5FU2; arm A), LV5FU2 plus cisplatin 50 mg/m2 (1-hour infusion) on day 1 or 2 (arm B), or LV5FU2 plus irinotecan 180 mg/m2 (2-hour infusion) on day 1 (arm C). Results The overall response rates, which were confirmed by an independent expert panel, were 13% (95% CI, 3.4% to 23.3%), 27% (95% CI, 14.1% to 40.4%), and 40% (95% CI, 25.7% to 54.3%) for arms A, B, and C, respectively. Median progression-free survival and overall survival times were 3.2 months (95% CI, 1.8 to 4.6 months) and 6.8 months (95% CI, 2.6 to 11.1 months) with LV5FU2, respectively; 4.9 months (95% CI, 3.5 to 6.3 months) and 9.5 months (95% CI, 6.9 to 12.2 months) with LV5FU2-cisplatin, respectively; and 6.9 months (95% CI, 5.5 to 8.3 months) and 11.3 months (95% CI, 9.3 to 13.3 months) with LV5FU2-irinotecan, respectively. Conclusion Of the three regimens tested, the combination of LV5FU2-irinotecan is the most promising and will be assessed in a phase III trial.

4566 Background: Docetaxel, in combination with cisplatin or oxaliplatin, has demonstrated efficacy against AGC. This randomized phase II trial evaluated two weekly docetaxel-based regimens to see which would be most promising according to objective response rate (ORR) as first-line therapy in AGC. Methods: Chemotherapy-naïve patients with measurable unresectable and/or metastatic gastric adenocarcinoma and a performance status ≤2 were randomly assigned to receive docetaxel (35 mg/m2) weekly on days 1 and 8 of a 21-day cycle plus either cisplatin (60 mg/m2 on day 1) (arm A) or oxaliplatin (120 mg/m2 on day 1) (arm B). Toxicity was assessed on days 1, 8, and 21 of each cycle, and response was evaluated every 2 cycles. Results: Between March 2007 and December 2008, 61 eligible patients entered. In Arm A, 29 patients were evaluable for objective response and 31 for safety. In Arm B, 28 patients were evaluable for objective response and 30 for safety. Median age was 52 years and disease status was comparable for both arms. Ten of 29 (34.5%) patients had a confirmed objective response in the arm A (95% confidence interval [CI] 17.1–51.8%) and 11 of 28 (39.2%) patients had a confirmed objective response in the arm B (95% CI 21.1- 57.2%). No significant difference was noted between the arms both for ORR (p=0.202) or for disease control (58.6% and 82.1%, respectively, p=0.082). Median progression free survival time was 4.4 month in the arm A and 4.3 months in the arm B (Hazard ratio = 0.936; 95% CI, 0.503–1.744; p = 0.836). There was no relevant difference in the occurrence of overall grade ¾ toxicity between the two arms (51.6% vs. 46.6%, respectively; p=0.800). Neutropenia was the most common grade 3/4 toxicity (32.3% vs. 36.6%, respectively). There was one treatment related death in Arm B. Conclusions: The preliminary results showed that both treatment arms have similar clinical efficacy as front-line treatment in AGC. Each regimen has a manageable tolerability profile. The accrual is ongoing. No significant financial relationships to disclose.

e18046 Background: Platinum and non-platinum doublet chemotherapy has similar efficacy in advanced NSCLC patients (pts). Bevacizumab (B) improves outcomes when added to platinum doublets, but its safety and efficacy in combination with non-platinum doublets is unknown. This study was designed to test the combination of B, docetaxel (D), and gemcitabine (G) in first-line treatment of advanced NSCLC. Methods: Pts with metastatic, non-squamous NSCLC, PS 0-1, and measurable disease by RECIST were enrolled in this open-label, single arm phase II trial. Pts received D (75 mg/m2) on d1, G (900 mg/m2) on d1 & 8, and B (15 mg/kg) on d1 every 21d for up to 6 cycles, followed by B maintenance until progression or 12 mos total. Pts received growth factor d9. CT scans were performed every 6 wks. The primary endpoint was 1-yr progression-free survival (PFS), with secondary endpoints of safety, objective response rate (ORR), overall PFS, and overall survival (OS). Pts with tumor cavitation, untreated brain metastases, and hemoptysis were excluded. Planned enrollment was 46. Results: 13 pts were enrolled from 12/2009 to 4/2011. Pt characteristics: Median age 63 (35-69), 85% male, PS 0 (38%), PS 1 (62%). The median # of cycles of chemotherapy was 6 (1-6), median # cycles of B was 4 (1-15), with 2 pts coming off study prior to the first evaluation (1 grade 5 encephalopathy, 1 grade 4 febrile neutropenia). 5 pts (38%) had chemo dose reduction and 4 (31%) discontinued treatment for toxicity. 3 pts (23%) discontinued B prior to progression, 2 for tumor cavitation and 1 for grade 1 hemoptysis. The grade 3-5 non-hematologic toxicity rate was 69%, with 6 pts (46%) hospitalized with pneumonitis/pneumonia felt possibly related to study drugs. At this point enrollment was halted for safety concerns. The 1-yr PFS was 8%, and the median PFS was 6.9 mos (95% CI 2.0-NYR). 11 pts were evaluable for response, and 6 pts had partial responses for an ORR of 55%. The median OS was NYR with median follow up of 10.9 mos. Conclusions: The combination of B, D, and G was not tolerable at the doses and schedule used in this study. A formal phase I trial is needed if this combination is to be investigated further.

3595 Background: We conducted a phase II trial of gemcitabine with S-1 to evaluate the activity and toxicity of such a combination in heavily pre-treated patients (pts) with metastatic colorectal cancer (mCRC) who have progressed after treatment with fluoropyrimidines-, oxaliplatin- and irinotecan-containing regimens. Methods: 36 pts were enrolled, with the following characteristics: 19 females (53%), median age 57 (28-72), 30 EOGO PS 0-1 (83%). S-1 was given orally (30 mg/m2) b.i.d for 14 consecutive days and gemcitabine (1000 mg/m2) was given on days 1 and 8, every 21 days, until disease progression and for a maximum of 9 cycles. The primary endpoint was objective response rate (ORR). Results: The median number of cycles was 5 (range 1-9), ORR was 16.7% (95% confidence interval [CI] 4.5-28.9%) and disease control rate was 61.1% (95% CI 45.2-77.0%) with 6 partial responses and 16 stable diseases. Median duration of disease control was 5.8 months (95% CI 4.1-7.5 months). Median progression-free survival was 3.7 months (95% CI 2.2-5.2 months) and median overall survival was 10.0 months (95% CI 7.4-12.7 months). Grade 3-4 toxicities were rare (neutropenia 12%, anemia 11%, leucopenia 6%, thrombocytopenia 3% and diarrhea 3%). Conclusions: Combination chemotherapy with gemcitabine and S-1 was a convenient, well tolerated and efficacious for heavily pre-treated pts with mCRC. This regimen warrants further evaluation in pts with good PS but no further treatment options.

454 Background: Pmab has demonstrated significant improvement in progression-free survival (PFS) in pts with WT KRAS mCRC as 2nd-line tx in a phase III trial comparing pmab + FOLFIRI vs FOLFIRI alone. Here, we describe the results of SPIRITT, a multicenter, randomized phase II study evaluating pmab + FOLFIRI and bev + FOLFIRI in pts with WT KRAS mCRC previously treated with a 1st-line bev + oxaliplatin (Ox)-based chemotherapy regimen. Methods: Pts were randomized 1:1 to pmab 6.0 mg/kg + FOLFIRI Q2W or to bev 5.0 or 10.0 mg/kg + FOLFIRI Q2W. Eligibility criteria included: WT KRAS mCRC, ECOG ≤ 1, no prior irinotecan or anti-EGFR tx, and tx failure of prior 1st-line bev + Ox-based therapy (≥ 4 cycles). The primary endpoint was PFS; secondary endpoints included overall survival (OS), objective response rate (ORR), and safety. No formal hypothesis was tested. Results: 182 pts with WT KRAS mCRC were randomized. All pts received tx. Efficacy results are shown (table). Worst grade of 3/4 adverse events (AE) occurred in 78% of pts in the pmab + FOLFIRI arm and 65% in the bev + FOLFIRI arm. Grade 5 AEs occurred in 7% of pts in the pmab + FOLFIRI arm and 7% in the bev + FOLFIRI arm. Tx discontinuation due to any AE was 29% in the pmab + FOLFIRI arm and 25% in the bev + FOLFIRI arm. Conclusions: In this estimation study of pts with WT KRAS mCRC that previously received bev + Ox-based tx, the PFS hazard ratio (HR) was 1.01 (95% CI: 0.68 - 1.50). The OS HR was 1.06 (95% CI: 0.75 - 1.49). The observed ORR was higher in the pmab + FOLFIRI arm. 54% of bev + FOLFIRI pts received subsequent anti-EGFR tx. The safety profile for both arms was similar to previously reported studies. Tx discontinuation rates due to AEs were similar between the arms. Clinical trial information: NCT00418938.

488 Background: We conducted a phase II trial of gemcitabine with S-1 to evaluate the activity and toxicity of such a combination in heavily pre-treated patients (pts) with metastatic colorectal cancer (mCRC) who have progressed after treatment with 5-fluorouracil (5-FU), oxaliplatin and irinotecan. Methods: 34 pts were enrolled, with the following characteristics: 17 (50%) females, median age 57 years (28-72), 28 (82%) ECOG PS 0-1. S-1 was given orally (30 mg/m2) b.i.d for 14 consecutive days and gemcitabine (1000 mg/m2) was given on days 1 and 8, every 21 days, until disease progression and for a maximum of 9 cycles. The primary endpoint was objective response rate (ORR). Results: The median number of cycles was four (range 1-9). ORR was 14.7% (95% confidence interval [CI] 2.8-26.6) and disease control rate was 58.8% (95% CI 42.2-75.3) with five partial responses and fifteen stable diseases. Median duration of disease control was 5.1 months (95% CI 3.3-7.0). Median progression-free survival was 3.2 months (95% CI 2.3-4.1) and median overall survival was 11.8 months (95% CI 7.0-16.5). Grade 3-4 toxicities were neutropenia (12%), anemia (12%), thrombocytopenia (3%) and diarrhea (3%). Conclusions: Combination chemotherapy with gemcitabine and S-1 was well tolerated and efficacious for heavily pre-treated mCRC pts, and could be an alternative for pts with good PS but no further treatment options.

PurposeNo established treatment exists for pancreatic neuroendocrine tumor (NET) progression after failure of chemotherapy. Everolimus (RAD001), an oral inhibitor of mammalian target of rapamycin, in combination with octreotide has demonstrated encouraging antitumor activity in patients with NETs.Patients and MethodsThis open-label, phase II study assessed the clinical activity of everolimus in patients with metastatic pancreatic NETs who experienced progression on or after chemotherapy. Patients were stratified by prior octreotide therapy (stratum 1: everolimus 10 mg/d, n = 115; stratum 2: everolimus 10 mg/d plus octreotide long-acting release [LAR], n = 45). Tumor assessments (using Response Evaluation Criteria in Solid Tumors) were performed every 3 months. Chromogranin A (CgA) and neuron-specific enolase (NSE) were assessed monthly if elevated at baseline. Trough concentrations of everolimus and octreotide were assessed.ResultsBy central radiology review, in stratum 1, there were 11 partial responses (9.6%), 78 patients (67.8%) with stable disease (SD), and 16 patients (13.9%) with progressive disease; median progression-free survival (PFS) was 9.7 months. In stratum 2, there were two partial responses (4.4%), 36 patients (80%) with SD, and no patients with progressive disease; median PFS was 16.7 months. Patients with an early CgA or NSE response had a longer PFS compared with patients without an early response. Coadministration of octreotide LAR and everolimus did not impact exposure to either drug. Most adverse events were mild to moderate and were consistent with those previously seen with everolimus.ConclusionDaily everolimus, with or without concomitant octreotide LAR, demonstrates antitumor activity as measured by objective response rate and PFS and is well tolerated in patients with advanced pancreatic NETs after failure of prior systemic chemotherapy.
