4032 Background: PNET has long had few effective therapies other than chemotherapy. 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 was 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: 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.

260 Background: Recent placebo-controlled phase III trials of the mTOR inhibitor everolimus and the VEGF/ PDGF receptor inhibitor sunitinib in PNET noted improved progression-free survival (PFS). However, objective response rates (RR) with these agents are <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 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 11 of the first 25 (44%) evaluable patients. 20 of 25 (80%) patients were progression-free at 6 months. Both endpoints exceeded pre-defined criteria to continue enrollment. For 35 evaluable patients, the most common grade 3-4 adverse events attributed to therapy were leukopenia (12%), hypertension (12%), hyperglycemia (12%), mucositis (9%), and fatigue (9%). Conclusions: The combination of TEM/BEV has substantial activity in a multi-center phase II trial with RR of 44%, 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.

Purpose This multicentric, randomized, two-stage phase II trial evaluated three simplified weekly infusional regimens of fluorouracil (FU) or FU plus folinic acid (FA) and cisplatin (Cis) with the aim to select a regimen for future phase III trials. Patients and Methods A total of 145 patients with advanced gastric cancer where randomly assigned to weekly FU 3,000 mg/m2/24 hours (HD-FU), FU 2,600 mg/m2/24 hours plus dl-FA 500 mg/m2 or l-FA 250 mg/m2 (HD-FU/FA), or FU 2000 mg/m2/24 hours plus FA plus biweekly Cis 50 mg/m2, each administered for 6 weeks with a 1-week rest. The primary end point was the response rate. Results Confirmed responses were observed in 6.1% (two of 33) of the eligible patients treated with HD-FU, in 25% (12 of 48, including one complete remission [CR]) with HD-FU/FA, and in 45.7% (21 of 46, including four CRs) with HD-FU/FA/Cis. The HD-FU arm was closed after stage 1 because the required minimum number of responses was not met. The median progression-free survival of all patients in the HD-FU, HD-FU/FA, and HD-FU/FA/Cis arm was 1.9, 4.0, and 6.1 months, respectively. The median overall survival was 7.1, 8.9, and 9.7 months, and the survival rate at 1 year was 24.3%, 30.3%, and 45.3%, respectively. Grade 4 toxicities were rare. The most relevant grade 3/4 toxicities were neutropenia in 1.9%, 5.4%, and 19.6%, and diarrhea in 2.7%, 1.9%, and 3.9% of the cycles in the HD-FU, HD-FU/FA, and HD-/FU/Cis arms, respectively. Conclusion Weekly infusional FU/FA plus biweekly Cis is effective and safe in patients with gastric cancer.

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]

We reviewed all fully published clinical trials assessing anti-angiogenic agents in sarcoma patients (last issue, January 13, 2020). Anti-angiogenic macromolecules (e.g., bevacizumab or ombrabulin) provide disappointing results. Many multikinase inhibitors have been assessed with non-randomized phase II trials with limited samples and without stratification according to histological subtypes, therefore interpretation of such trials is very challenging. On the contrary, pazopanib, regorafenib, and sorafenib have been assessed using double-blind placebo-controlled randomized phase II or phase III trials. Compared to placebo, sorafenib demonstrates activity in desmoid-type fibromatosis patients. Based on results of phase 3 trial, pazopanib had obtained approval for treatment of pretreated non-adipocytic soft tissue sarcoma. Regorafenib is currently assessed in several clinical settings and provides significant improvement of progression-free survival in pre-treated non-adipocytic soft tissue sarcoma and in advanced pretreated osteosarcoma. Multikinase inhibitors are a breakthrough in sarcoma management. Many trials are ongoing. Nevertheless, predictive factors are still missing.

Patients with locally advanced or metastatic gastric adenocarcinoma received an i.v. bolus of 4′-epi-doxorubicin, 75/mg/m2/cycle, every 21 days. Partial responses were observed in 5 of 23 evaluable patients (21.7%). Treatment was generally well tolerated and toxicity was mild. The response rate to epirubicin appears to be very similar to that reported for doxorubicin. Larger doses of epirubicin could be safely used in future studies, and further evaluation of epirubicin in phase III trials is indicated.

Abstract BACKGROUND No standard of care has been established for patients with progressive glioblastoma (rGBM). Previous studies suggested that bevacizumab (BEV) is safe and produces responses that result in a decreased use of glucocorticoids and increased progression-free survival (PFS) with an unclear effect on overall survival (OS). Crossover to BEV in the control arm is the possible reason why the advantage of BEV has not been proven in Phase III trials. We retrospectively analyzed own results of BEV treatment in rGBM. MATERIAL AND METHODS 81 patients progressed after radiotherapy plus concomitant and maintenance temozolomide (TMZ) and undergo BEV as monotherapy (BevMo, 11 patients) or in combinations (Irinotecan (BevI) - 53, lomustine (BevL)- 11, TMZ (BevT) - 6. Median age 54 years. Among them 33 patients were re-irradiated: 11 - radiosurgery (RS), 20 fractionated irradiation (RT), 2 - RS+RT. 33 patients continued BEV after progression with changing or adding cytostatic. PFS was calculated from the date of verification, PFS1 - from the date of 1-st progression, PFS2 - from the date of 2-nd progression. RESULTS Median PFS was 9.0 ([CI] 7.0–10.9) months. Median PFS1 was 10.5 ([CI] 8.1–12.9) months. In the BevMo, BevI, BevL, BevT group PFS1 was 15.7, 10.1, 10.5, 13.2 months, respectively, p=0.7. Objective response (OR) was reached in 34%, stable disease (SD) in 28%, progression (PD) in 37% patients. 16 patients stopped BEV without progression (4-patient`s decision, 7- doctor`s decision, 2 - adverse event, 3 - concomitant disease). Median time of BEV treatment was 11.6 months. Median BEV-free interval till progression was 3.7 months. 33 patients continued or restarted BEV after progression. Median PFS2 was 8.0 ([CI] 4.9–11.1) months. The median OS from the date of 1-st progression was 23.5 months ([CI] 18.7–27.4). In groups with RT, RS, RS+RT and no re-irradiarion OS was 24.6 ([CI] 17.6–31.5), 35.4 ([CI] 35.0–35.8), 17.8, 20.6 ([CI] 15.2–26.0), respectively, p=0.2. CONCLUSION OS in our group is outrageously high. Maintaining BEV after progression was effective. In our group BEV discontinuation led to rapid progression. The resumption of Bev with progression was effective, which indicates the advisability of its continuous application.

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.
