4525 Background: Pancreatic cancer cells and surrounding stroma are known to overexpress SPARC (secreted protein acid rich in cysteine), which is associated with poor clinical outcomes. nab-P, an albumin-bound nanoparticle form of paclitaxel increased tumor accumulation of paclitaxel through binding of albumin to SPARC. This disease specific phase 1 study was designed to evaluate the safety and efficacy of G + nab-P and the correlation of response with tumor SPARC and serum CA19–9 levels. Methods: nab-P doses (100–150 mg/m2) + (G) (1000 mg/m2) were given on days 1, 8, and 15 of a 28-day cycle to pts with metastatic pancreatic adenocarcinoma and with no prior chemotherapy for their metastatic disease. Level 3 SPARC staining by immunohistochemistry was considered positive. Results: 63 pts received treatment. The most common grade 3 and 4 adverse event that occurred in >20% of pts was neutropenia. Nine (18%) pts and 4 (8%) pts had a grade 3/4 event, respectively. Neuropathy was also observed. One combination-associated death due to sepsis occurred at the 150 mg/m2 nab-P level. Serial PET scans of 53 pts with outside adjudication to date showed 12 (23%) complete responses, 29 (55%) partial responses (PRs) and 4 (8%) stable disease (SD). By RECIST criteria, of the 49 pts evaluable to date, 1(2%) had CR, 12 (24%) had PR, and 20 (41%) had SD. The median survival was 9 months to date. SPARC data were available for 35 pts, of which 10 (29%) were SPARC+ and 25 (71%) were SPARC-. Of these, 27 pts had evaluable response data. Pts that were SPARC+ (8/27) were more likely to be responders (6/8, 75%) than pts who were SPARC- (5/19, 26%), P = 0.03, Fisher's exact test. Median progression-free survival (PFS) increased from 4.8 months for SPARC- pts (22 pts) to 6.2 months for SPARC+ pts (9 pts); however, these data are still immature. Of 45 pts with elevated CA19–9 at baseline, 42 (93%) had maximum decrease of >40% with a median maximum decrease of 92%. Conclusions: The combination of nab-P and G was generally well tolerated and had substantial enough antitumor activity in patients with pancreatic cancer to warrant a phase III clinical trial. SPARC+ status in these patients was associated with higher response rate and longer PFS. [Table: see text]

370 Background: The Phase 1 portion of a Phase 1/2 trial of Necuparanib (“Necu”) combined with nab-paclitaxel (nabP) + gemcitabine (gem) in patients with metastatic pancreatic cancer (ClinicalTrials.gov Identifier NCT01621243) showed acceptable safety and tolerability and encouraging signals of activity and established a dose for the randomized, placebo (PBO)-controlled Phase 2 portion. Methods: In Phase 2, patients received daily s.c. injections of either 5 mg/kg Necu daily or PBO, combined with i.v. 125 mg/m2 nabP and 1000 mg/m2 gem (Days 1, 8, 15 of each 28-day cycle). The primary endpoint was overall survival (OS); other endpoints included progression-free survival (PFS), response rates, safety, and CA19.9 levels. An interim futility analysis was conducted in July 2016 once 57 deaths (50% of the target number of 114 events required for trial completion) had occurred. Results: The analysis was conducted on data from 120 randomized patients (62 Necu, 58 PBO). The Z-score for futility was -0.42 (prespecified boundary of -0.148 was crossed as actual score was lower). Median OS was Necu = 10.71 and PBO = 9.99 months; hazard ratio (HR) = 1.12 (favoring PBO); OS curves were intertwined. PFS was Necu = 5.52 and PBO = 6.93 months; HR = 0.97. RECIST response rates were comparable between arms: complete response, Necu = 0%, PBO = 3%; partial response, Necu = 26%, PBO = 26%; stable disease, Necu = 31%, PBO = 34%; disease control rate, Necu = 56%, PBO = 64%. The most common Grade 3+ adverse events (AEs) were neutropenia (Necu = 33%, PBO = 33%), thrombocytopenia (Necu = 27%, PBO = 5%), and anemia (Necu = 22%, PBO = 11%). There were lower rate of serious AEs with Necu (48%) vs. PBO (60%). Modest increases in APTT, AST, and ALT were noted following Necu relative to PBO. 23% of Necu and 5% of PBO patients were IgG positive with an anti-heparin/PF4 antibody titer of ≥ 0.4 at any time. There were no treatment differences for decreases in CA19.9. Conclusions: No new safety signals were observed and the toxicity profile was considered manageable; however, Necu in combination with nabP and gem did not show a sufficient level of efficacy in metastatic pancreatic cancer to warrant continued enrollment. Clinical trial information: NCT01621243.

<b><i>Introduction:</i></b> Patients with advanced pancreatic cancer have a poor prognosis. FOLFIRINOX (FFX) and gemcitabine plus nab-paclitaxel (GnP) have been established as first-line treatment, but they have not been confirmed as second-line treatment after FFX. The aim of this study was to evaluate the safety and efficacy of GnP as second-line therapy after FFX in patients with unresectable pancreatic cancer. <b><i>Methods:</i></b> Twenty-five patients with unresectable pancreatic cancer were enrolled. The patients were treated with GnP after FFX between September 2015 and September 2019. Tumor response, progression-free survival (PFS), overall survival (OS), and incidence of adverse events were evaluated. <b><i>Results:</i></b> The response rate, disease control rate, median PFS, and median OS were 12%, 96%, 5.3 months, and 15.6 months, respectively. The common grade 3 or 4 adverse events were neutropenia (76%) and anemia (16%). <b><i>Conclusions:</i></b> GnP after FOLFIRINOX is expected to be one of the second-line recommendations for patients with unresectable pancreatic cancer.

439 Background: Weekly nab-P + Gem is a new option for first-line treatment (Tx) of mPC. In the MPACT trial, nab-P/Gem demonstrated superior overall survival (OS; primary endpoint) vs Gem alone as first-line Tx of mPC (Table). Here we report a subgroup analyses evaluating the efficacy and safety outcomes with nab-P + Gem vs Gem alone from the Canadian cohort of the MPACT trial. Methods: Previously untreated pts (N = 861) with mPC were randomized 1:1 (stratified by Karnofsky Performance Status [KPS], region, and the presence of liver metastases) to receive nab-P 125 mg/m2 + Gem 1000 mg/m2 on days 1, 8, and 15 of each 28-day cycle or Gem 1000 mg/m2 weekly for 7 weeks followed by 1 week of rest (cycle 1) and then days 1, 8, and 15 of each 28-day cycle (cycle ≥ 2). Results: 63 pts from Canada enrolled in the MPACT trial. Baseline pt characteristics were well balanced. Median age was 61 years and KPS was similar for both groups and comparable to the intent-to-treat (ITT) populations. Primary lesion in the pancreatic head was more common among pts in the nab-P + Gem vs Gem arm (55% vs 30%); use of biliary stent was similar (33% nab-P + Gem; 27% Gem). Median OS and progression-free survival (PFS) were longer with nab-P + Gem vs Gem (Table). Median Tx duration was 4.2 mo with nab-P + Gem vs 3.2 mo with Gem. Use of subsequent therapy was 30% in the nab-P + Gem arm vs 43% in the Gem arm. The median relative dose intensity for Gem was similar in each arm (81% nab-P + Gem vs 85% Gem). The most common grade ≥ 3 AEs for nab-P + Gem vs Gem were neutropenia (22% vs 10%), fatigue (34% vs 33%), and neuropathy (25% vs 0%). Conclusions: Canadian pts participating in MPACT were similar to the ITT population and nab-P + Gem was well tolerated and showed improved median OS, PFS, and ORR vs Gem alone, although not statistically significant (likely due to the small number of pts). Clinical trial information: NCT00844649. [Table: see text]

351 Background: FOLFIRINOX is an approved regimen for metastatic pancreatic cancer (mPC). We performed a modification in FOLFIRINOX schedule, using nab-paclitaxel (nab-p) to obtain two regimens that could be as effective and less toxic than the original triplet. NabucCO study was a randomized phase II trial to assess activity and toxicity of nab-p instead of either oxaliplatin (Nab-FOLFIRI) or irinotecan (Nab-FOLFOX) in first line setting. Previous dose–finding NabucCO study defined that maximum tolerated dose of nab-p with FOLFIRI is 120 mg/m2, and with FOLFOX is 160 mg/m2. Methods: The study was a 1:1 parallel arm, open label, not comparative one to assess overall response rate (ORR) of Nab-FOLFIRI and Nab-FOLFOX as primary end-point. Patients (pts) with PS 0-1, untreated for mPC were randomized to receive leucovorin 400 mg/m2, 5FU bolus 400 mg/m2, 5FU 48h ci 2400 mg/m2, irinotecan 180 mg/m2 plus nab-p 120 mg/m2 (arm A) or leucovorin 400 mg/m2, 5FU bolus 400 mg/m2, 5FU 48h ci 2400 mg/m2 and oxaliplatin 85 mg/m2 iv plus nab-p 160 mg/m2 (arm B) every 2 weeks for up to 12 cycles. Secondary end points were clinical benefit rate (CBR), progression free survival (PFS), overall survival (OS), and safety. Results: From November 2015 to January 2017, 84 pts were treated (42 for each arm). Median age was 60 years (29-65) in arm A and 64 years (47-64) in arm B. The ORR was 31 % for both schedules, with a CBR of 69% and 71%, respectively. At a median follow-up of 11.4 months for arm A and 14.5 months for arm B (censored on august, 31th 2017), 1-year survival is 41% and 50%, respectively. For Nab-FOLFIRI PFS and mOS were 6 months (90% CI: 4.9-8.0) and 13.2 months (90% CI: 8.3-14.8), while in Nab-FOLFOX were 5.6 months (90% CI:4.9-7.2) and 10.8 months (90% CI: 8.4-12.8). Grade ≥3 toxicities in arm A were neutropenia (19%) and febrile neutropenia (12%). In arm B, main grade ≥3 toxicities were neutropenia (29%), fatigue (14%), peripheral neuropathy (7%). No toxic death were registered. Conclusions: Nab-FOLFIRI and Nab–FOLFOX demonstrated a similar activity to FOLFIRINOX, with better safety profile in terms of neutropenia, fatigue and neuropathy. These results could justify a future phase III evaluation. Clinical trial information: NCT02109341.

21 Background: Objectives: (1) To investigate the MTD of ABI-009 when given with nivolumab, a PD-1 inhibitor, in previously treated advanced undifferentiated pleomorphic sarcoma, liposarcoma, chondrosarcoma, osteosarcoma and Ewing sarcoma; (2) To investigate the disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) of this combination therapy in the above mentioned patient group, and (3) To correlate PFS with PD-L1 and other biomarker expression in patients’ tumors. Methods: This is an IRB approved protocol with 2 parts. The Phase 1 part is a dose-finding study using the “cohort of three design”, wherein standard doses of nivolumab 240 mg is given iv every 3 weeks (Day 1 of every 21-day Cycle). ABI-009 will be given IV on Days 8 and 15 of each cycle starting on Cycle 2 following the 2nd nivolumab dose. The starting dose of ABI-009 is 56 mg/m2, and sequentially escalating doses are 75, and 100 mg/m2. The Phase 2 part of study will enroll 31 additional patients to further assess efficacy and safety at the MTD. Results: The Phase 1 part of study is closed, after 9 patients were treated successfully at 3 dose levels. No dose-limiting toxicities (DLTs) were observed, the MTD was not reached, and 100 mg/m2 ABI-009 was designated as the recommended phase 2 dose. Safety analysis: At Dose 1 (n=3): Grade 3 treatment-related adverse events (TRAEs) included hyperdyslipidemia (n=1), and hyperglycemia (n=1). At Dose 2 (n=3): Grade 3 TRAEs included increased ALT (n=1). At Dose 3 (n=3): Grade 3 TRAEs included hypophosphatemia (n=1). Seven of 9 patients have discontinued treatment: 5 patients due to PD, 2 with SD opted to stop treatment due to drug-related Grade 2 AEs (pruritus, acneiform rash, and 2 with SD are still on therapy at Dose 3. Conclusions: The primary objective has been met with no DLTs, the MTD was not reached and Dose 3 has been designated as the phase 2 dose of ABI-009 which is on-going. Clinical trial information: NCT03190174.

LBA3 Background: The prognosis for patients with AGC after failure of first-line chemotherapy is poor. Currently, there is no level 1 evidence established for second-line treatment. EVE inhibits the PI3K/Akt/mTOR pathway, a key regulator of cell proliferation, metabolism, and angiogenesis, and has shown efficacy against AGC in preclinical and phase I/II studies. Methods: In a randomized, double-blind, multicenter, phase III study, patients age ≥18 years with confirmed AGC and disease progression after 1 or 2 lines of systemic chemotherapy were randomized 2:1 to oral EVE 10 mg/d plus best supportive care (BSC) or placebo (PBO) plus BSC. Randomization was stratified by region (Asia vs rest of world) and previous lines of chemotherapy (1 vs 2). Study drug was discontinued upon progression or unacceptable toxicity. The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), overall response rate (ORR), and safety. The final analysis was performed when 526 deaths occurred. Results: A total of 656 patients from 23 countries were enrolled from Jul 2009 to Dec 2010; 439 were randomized to EVE, 217 to PBO. Baseline characteristics were well balanced between arms; 73.6% were men, 55.3% were enrolled in Asia, 47.7% received 1 previous line of chemotherapy, and 50.6% had a gastrectomy. Median OS was 5.39 months with EVE vs 4.34 months with PBO (HR, 0.90; 95% CI, 0.75-1.08; P=0.1244). Median PFS per local investigator assessment was 1.68 months with EVE vs 1.41 months with PBO (HR, 0.66; 95% CI, 0.56-0.78; p<0.0001). Six-month PFS estimates were 12.0% with EVE and 4.3% with PBO. OS and PFS results were consistent across the various subgroups. ORR (95% CI) was 4.5% (2.6%-7.1%) with EVE vs 2.1% (0.6%-5.3%) with PBO. The most common grade 3/4 adverse events were anemia (16.0% with EVE vs 12.6% with PBO), decreased appetite (11.0% vs 5.6%), and fatigue (7.8% vs 5.1%). Conclusions: EVE monotherapy did not significantly improve OS in patients with AGC previously treated with 1 or 2 lines of systemic chemotherapy. EVE did improve PFS. Results for OS and PFS were consistent across the various subgroups. The safety profile was consistent with that previously observed with EVE.

e20033 Background: A recent phase III trial of nab-paclitaxel (nab-P, 130 nm albumin-bound paclitaxel) vs dacarbazine (DTIC) in mM demonstrated a significant improvement in progression-free survival (PFS). An economic analysis was applied to the results of this trial. Methods: Chemotherapy naive stage IV mM patients received nab-P 150 mg/m2 on days 1, 8, and 15 every 4 weeks or DTIC 1000 mg/m2 every 3 weeks. 529 patients were randomized to nab-P (n = 264) or DTIC (n = 265). The primary endpoint was independently assessed PFS, with overall survival (OS) as a secondary endpoint. Costs of nab-P and DTIC were taken from published 2013 Medicare reimbursement rates. A literature review identified costs for expected adverse events (AE), administration, and recently approved mM treatments. Results: In the intent-to-treat population, median PFS was 4.8 and 2.5 months in the nab-P and DTIC arms, respectively (HR: 0.792; P = 0.044). Median OS at the time of an interim analysis was 12.8 months with nab-P and 10.7 months with DTIC (HR: 0.831; P = 0.094; determination of ultimate statistical significance is pending full analysis at study conclusion). The most common grade ≥3 treatment-related AEs were neuropathy (nab-P: 25% vs DTIC: 0%) and neutropenia (nab-P: 20% vs DTIC: 10%). Grade 4 neutropenia rates were similar between arms (nab-P: 3% vs DTIC: 4%). Median time to neuropathy improvement by >1 grade was 28 days. Median treatment duration was 3 months with nab-P vs 2.1 months with DTIC. Incremental costs per patient were $23,359 ($24,663 for nab-P vs $1,304 for DTIC) including drug, infusion, and AE management costs. These costs compare favorably to incremental costs of over $50,000 for newly approved therapies with similar median OS gains vsDTIC. Conclusions: nab-P is the only chemotherapy in a phase III trial to demonstrate a significant and clinically meaningful delay in disease progression over dacarbazine. Total costs are attractive in the context of other agents recently approved for mM. Further analysis is merited when final OS is available. Clinical trial information: NCT00864253.

8528 Background: RRMM patients (pts) who fail lenalidomide (LEN) and bortezomib (BORT) have poor prognosis. High-risk cytogenetics predict shorter survival. POM + LoDEX has demonstrated efficacy in pts with prior LEN and BORT and high-risk cytogenetics. MM-003 is an open-label, multicenter, phase III trial comparing POM + LoDEX vs. HiDEX in RRMM pts who failed LEN and BORT treatment (Tx) and have progressed on their last therapy. Methods: Pts must have been refractory to the last prior Tx (progressive disease [PD] during or within 60 days) and failed LEN and BORT after ≥ 2 consecutive cycles of each (alone or in combination). Randomization was 2:1 to POM 4 mg D1–21 + DEX 40 mg (20 mg for pts aged > 75 y) weekly; or DEX 40 mg (20 mg for pts aged > 75 y) D1–4, 9–12, and 17–20 (28-day cycles). Tx continued until PD or unacceptable adverse events (AEs). The primary endpoint was progression-free survival (PFS). Secondary endpoints included OS and AEs. This analysis examined pts meeting modified high-risk cytogenetic criteria—del(17p13) and/or t(4p16/14q32). Results: 302 pts received POM + LoDEX, and 153 pts received HiDEX. 225 and 107 pts, respectively, were evaluable for cytogenetics. Baseline characteristics were similar. Median PFS and OS were significantly longer with POM + LoDEX vs. HiDEX, regardless of cytogenetic risk (Table). The most common grade 3/4 AEs were neutropenia, anemia, and infection (Table). Discontinuation due to AE was low: 4% vs. 6% (high risk) and 10% vs. 4% (standard risk). Conclusions: Median PFS and OS were significantly longer with POM + LoDEX vs. HiDEX in pts with cytogenetically-defined high-risk disease, consistent with results from the intent-to-treat population. Tolerability was acceptable. POM + LoDEX should be considered a new Tx option in pts failing LEN and BORT. Clinical trial information: NCT01311687. [Table: see text]

710 Background: In the CORRECT phase III trial (NCT01103323), the multikinase inhibitor REG significantly improved overall survival (OS) and PFS vs placebo in patients with mCRC who had disease progression after other standard therapies (HR for OS: 0.77; 1-sided p =0.0052; Grothey 2013). A post-hoc exploratory subgroup analysis was conducted to evaluate patients in the REG treatment group who had a PFS longer than 4 months (long-PFS) defined as patients who progressed, died, or discontinued treatment for other reasons after 4 months. Methods: Of the505 patients randomized to REG in CORRECT, 98 (19.4%) were classified as having a long-PFS benefit. Baseline characteristics, safety, and dosing parameters were analyzed descriptively. Results: The long-PFS subpopulation was representative of the overall study population (Table). Long-PFS patients received a median of 6 cycles of REG (1-12), 92% received ≥5 cycles, and 20% had > 8 cycles. Overall 34% of patients had dose reductions and 87% had dose interruptions. The actual mean daily dose was 139 mg and the mean percent of the planned dose was 81%. Adverse events (AE) of any grade were experienced by all long-PFS patients, and the most common grade ≥3 AEs were hand-foot skin reaction (20%), hypertension (17%), diarrhea (17%), and fatigue (16%). Conclusions: A subset of 98 (19.4%) patients treated with REG in the CORRECT study had a PFS > 4 months, confirming the clinical benefit and tolerability of REG as a treatment option for patients with mCRC. Prospective validation of these findings in conjunction with biomarker analysis from real-life clinical experience is needed. Clinical trial information: NCT01103323. [Table: see text]

LBA148 Background: nab-Paclitaxel (nab-P, 130 nm albumin-bound paclitaxel) provides tumor selective localization via transcytosis across the endothelium, potential tumor uptake via macropinocytosis, and improved pharmacokinetics vs cremophor-paclitaxel. In vitro, nab-P increased tumoral gemcitabine (G) levels, and in a phase I/II study in metastatic pancreatic cancer (mPC) nab-P + G showed promising activity. Methods: Patients (pts) with mPC were randomized to nab-P 125 mg/m2, followed by G 1000 mg/m2 on days 1, 8, and 15 every 4 weeks or G 1000 mg/m2 weekly for 7 weeks (cycle 1), then on days 1, 8, and 15 every 4 weeks (≥ cycle 2). For the primary endpoint of overall survival (OS), 608 events from 842 patients provided a power of 0.9 to detect a HR of 0.769 (2-side α = 0.049). Results: 861 pts received therapy. Baseline pt characteristics were well balanced. Median age was 63 years, Karnofsky performance status was 90-100 in 60% and ≤80 in 40% of pts, 43% had head of pancreas lesions, 84% had liver and 39% had lung metastases, and 52% of pts had CA19-9 ≥59 x ULN. Treatment duration was 4 vs 3 months in nab-P + G vs G. The relative protocol G dose was 75% vs 85% in nab-P + G vs G; nab-P dose was 81%. OS, progression-free survival (PFS), time to treatment failure (TTF), and overall response rate (ORR) were significantly improved in the nab-P + G arm (Table). Most common grade ≥3 AEs were neutropenia (38% vs 27%), fatigue (17% vs 7%), and neuropathy (17% vs 1%) in the nab-P + G vs G arms. Grade ≥3 neuropathy improved to grade ≤1 in 29 days. Febrile neutropenia was reported in 3% (nab-P + G) vs 1% (G) pts. Conclusions: In this multinational, multiinstitutional study, nab-P + G was well tolerated and superior to G with statistically significant and clinically meaningful results in all endpoints and across subgroups.
