637 Background: Effective therapies are limited for advanced metastatic pancreatic ductal adenocarcinoma (PDAC) patients (pts) who have progressed after 1st line gemcitabine-based chemotherapy (Gem). FOLFOX has clinical benefit in Gem-refractory PDAC pts. A phase 1 trial demonstrated promising activity with pegilodecakin (PEG; pegylated IL-10) and FOLFOX in Gem-refractory PDAC pts, providing rationale for the phase 3 trial (SEQUOIA; NCT02923921). Methods: SEQUOIA is a randomized phase 3 study of FOLFOX alone or with PEG in Gem-refractory PDAC pts. Pts were randomized 1:1, excluding pts with prior surgery and radiation, and received FOLFOX ( dI-Leucovorin [400 mg/m2], oxaliplatin [85 mg/m2] followed by bolus 5-FU [400 mg/m2], and a 46-48 hr infusion of 5-FU [2400 mg/m2]) on day 1 of a 14-day cycle up to 12 cycles. PEG + FOLFOX arm received PEG (0.4 mg/d if ≤80kg and 0.8mg/d if > 80 kg) on Days 1-5 then Days 8-12 + FOLFOX. Pts could continue PEG monotherapy (0.8mg/d if ≤ 80 kg and 1.6 mg/d if > 80 kg) after FOLFOX discontinuation. Primary objective was OS. Secondary objectives included PFS, ORR per RECIST 1.1, and safety. Assuming OS HR of 0.74, the study was powered to 85% at 2-sided α = 0.05 with ~566 pts to detect superiority of PEG + FOLFOX. Results: As of Sept 9, 2019, 567 pts were randomized to PEG + FOLFOX (283) or FOLFOX (284). The majority (94.7%) had 1st line Gem+nab paclitaxel. The mOS was similar between FOLFOX + PEG arm [5.8 months] and FOLFOX arm [6.3 months] with HR = 1.045 (95% CI [0.863, 1.265], p = 0.6565). No statistical difference was observed for PFS, mPFS was 2.1 months in both arms with HR = 0.981, (95% CI [0.808, 1.190], p = 0.8144). ORR was 4.6% on the PEG+FOLFOX arm and 5.6% on the FOLFOX arm. Grade ≥3 adverse events that were 5% higher on the PEG+FOLFOX arm included thrombocytopenia (25.2% vs. 3.6%), anemia (16.2% vs. 4.0%), neutropenia (29.5% vs. 22.7%), and fatigue (17.6% vs. 10.8%). Conclusions: The addition of PEG to FOLFOX did not improve efficacy (OS, PFS, ORR) in advanced PDAC pts who have progressed after 1st line Gem-containing therapy. Safety findings were consistent with previous data observed from PEG + chemotherapy; toxicity was manageable and tolerable. Clinical trial information: NCT02923921.

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.

4127 Background: In the NAPOLI-1 study, nal-IRI+5-FU/LV significantly increased median OS vs. 5-FU/LV control (6.1 vs. 4.2 mo; unstratified HR = 0.67 [0.49–0.92]; p = .012). This is a subgroup analysis by prior lines of mtx. Methods: Study methodology has been published (Wang-Gillam; Lancet 2016). This exploratory subgroup analysis compares outcomes in pts with 0–1 vs. ≥2 prior mtx lines, based on primary survival analysis data (cut-off February 2014) of the ITT population. Results: OS, PFS and CA19-9 response rates in pts with 0–1 (65.8% of pts) or ≥2 (34.2%) prior mtx lines are shown (see Table). Median OS for nal-IRI+5-FU/LV improved vs. 5-FU/LV by 2.1 mo to 6.2 mo (HR = 0.66; p = .03) in pts with 0–1 prior mtx lines and by 1.1 mo to 5.4 mo (HR = 0.68; p = .18) in pts with ≥2 prior mtx lines. The safety profile was similar between subgroups with nal-IRI+5-FU/LV (≥grade 3 drug-related AEs: 43 [55%] with 0–1 and 20 [51%] with ≥2 prior mtx lines). Conclusions: This post-hoc subgroup analysis shows significant increases for nal-IRI+5-FU/LV over 5-FU/LV in OS, PFS and CA19-9 response in pts with 0–1 prior mtx lines. Median OS benefit was less prominent in later lines, but conclusions are restricted by limited pt numbers. Clinical trial information: NCT01494506. [Table: see text]

11505 Background: AL3818 (Catequentinib, Anlotinib) is a novel, orally administered, small molecule tyrosine kinase inhibitor. The primary objective of this Phase 3 study is to evaluate the efficacy of AL3818 monotherapy in patients (pts) with synovial sarcoma (SS) comparing with dacarbazine in randomization setting. Methods: Patients with a diagnosis of synovial sarcoma requiring second line or further line treatment were eligible for enrollment. The regimen was a 21-day cycle with oral AL3818 administered on 14 days on and 7 days off. This phase 3 trial is randomized in 2:1 ratio of AL3818 comparing to dacarbazine with option of crossover after PD of dacarbazine treatment. Progression free survival (PFS) with Log Rank test is the primary endpoint and this trial for SS is currently completed enrolled in US and Italy. Results: Total 79 pts initiated treatment and are evaluable, 52 received AL3818 as treatment arm (T), and 27 received dacarbazine (D) as control arm (C). Arms T/C median ages were 40.5/42.0 years (range: 18-70+) and 20/16 (38.5%/59.3%) were male. Overall, PFS was 2.89 months (95% CI: 2.73 – 6.87) for AL3818 and 1.64 (95% CI: 1.45 – 2.70) for D. The PFS of study met the primary endpoint with a p-value of 0.0015 and a HR of 0.449 (95% CI: 0.270– 0.744). At the month 4, 6, and 12, the percentages of progression free patients for AL3818 were 48.1%, 42.3% and 26.9%; and for D were 14.85%, 11.1% and 3.7%. For grade 3 treatment-related adverse events, 12(23.1%) of pts experienced for AL3818 and 7(25.9%) of pts experienced for D. The most common AL3818 related grade 3 AEs were diarrhea (5.8%) and hypertension (3.8%). Conclusions: This phase III trial demonstrates improved disease control and superior progression free survival for AL3818 vs dacarbazine in advanced SS. In addition, the study further confirms the acceptable benefit-risk profile of AL3818 from the prior randomized Phase 2b soft tissue sarcoma study (NCT02449343). AL3818 is a meaningful treatment option for pts with advanced SS. Clinical trial information: NCT 03016819 Clinical trial information: NCT03016819.

5508 Background: MTC arises from parafollicular cells of the thyroid gland, accounts for 5-8% of thyroid cancers and represents an unmet medical need. Cabozantinib (cabo) is an oral inhibitor of MET, VEGFR2, and RET. We conducted a phase III study of cabo vs placebo (P) in pts with progressive, unresectable, locally advanced or metastatic MTC. Methods: Eligible pts were required to have documented RECIST progression within 14 months of screening. The primary efficacy measure was progression-free survival (PFS) as assessed by an independent review facility (IRF) using RECIST. Secondary efficacy measures included objective response rate (ORR) and overall survival (OS). The study has 90% power to detect a 75% increase in PFS and 80% power to detect a 50% increase in OS. Tumor assessments occurred every 12 weeks. Crossover between treatment arms was not allowed. Results: Between Sept 2008 and Feb 2011, 330 pts (median age 55 yrs; 67% male; 96% measureable disease; RET mutation status: pos 48%; neg 12%; unknown 39%; prior TKI exposure: yes 21%, no 78%, unknown 2%) were randomized 2:1 to cabo (140 mg free base [175 mg salt form] qd; n=219) or P (n=111). The planned primary PFS analysis included events through the date of the 138th event. As of 15June2011, 44.7% of pts on cabo and 13.5% on P were still receiving study treatment. Statistically significant PFS prolongation of 7.2 mo was observed; median PFS for cabo was 11.2 mo vs 4.0 mo for P (HR 0.28, 95% CI 0.19-0.40, p<0.0001). PFS results favored the cabo group across subset analyses including RET status and prior TKI use. ORR was 28% for cabo vs 0% for P (p<0.0001). An interim analysis of OS (44% of the 217 required events) did not show a difference between cabo and P. The most frequent grade ≥3 adverse events (cabo vs P) were diarrhea (15.9 vs 1.8%), palmar-plantar erythrodysesthesia (12.6 vs 0%), fatigue (9.3 vs 2.8%), hypocalcemia (9.3 vs 0%), and hypertension (7.9 vs 0%). Conclusions: This phase III study met its primary objective of demonstrating substantial PFS prolongation with cabo vs. P in a patient population with MTC and documented progressive disease in need of therapeutic intervention.

4084 Background: The median survival for patients (pts) with metastatic GE AC in phase III studies is <12 mos. Bev has demonstrated promising activity in metastatic GE AC when used in combination with cisplatin-based regimens in studies with patients from the Americas. We conducted a prospective phase II trial to investigate the efficacy of Bev in combination with mFOLFOX6 in pts with metastatic GE AC. Methods: Pts with previously untreated metastatic GE AC (gastric, GE junction, distal esophagus) received mFOLFOX6 (LV 400 mg/m2, 5-FU 400 mg/m2 bolus and 2400 mg/m2 over 46 hr continuous infusion, Ox 85 mg/m2) and Bev 10 mg/kg q 2 wks. Response by RECIST was evaluated by CT q 8 wks. Primary objective was time to progression (TTP); secondary objectives were safety, response rate (RR), and overall survival (OS). Results: 39 pts were enrolled between 09/08 and 06/12. Pt characteristics are as follows: median age, 59 yo (range 27-79); M/F, 31/8; ECOG PS 0/1, 11/28; gastric/distal E and GEJ, 13/26; metastatic sites: lymph nodes 23, liver 19, lung 9, peritoneum 9; >2 metastatic sites, 20; prior gastrectomy or esophagectomy, 7. Nine pts remain on study, and 15 pts are alive. Median # of cycles administered is 11 (range 4 - >31). RR is 56.4% (4 CR, 18 PR). Median TTP is 8.2 mos. Median OS is 15.2 mos. Three pts survived >24 mos. Grade 3/4 toxicities include neutropenia (13, 33.3%), neuropathy (8, 20.5%), DVT/PE (5, 12.8%), thrombocytopenia (3, 7.7%), anemia (1, 2.6%), hypertension (1, 2.6%), and proteinuria (1, 2.6%). We observed no GI perforations or grade 3/4 GI hemorrhagic events. Conclusions: FOLFOX6/Bev is well tolerated and associated with increased TTP and OS in pts with metastatic GE AC compared to historical data from similar populations treated without Bev. Our findings validate previous studies with Bev in combination with cisplatin-based regimens in pts from the Americas with metastatic GE AC. This study is supported by Genentech. Clinical trial information: NCT00673673.

4031 Background: Capecitabine is an oral fluoropyrimidine that has demonstrated similar efficacy to 5-FU/LV in the 1st-line treatment of MCRC. Most patients now receive multi-agent chemotherapy and FOLFOX4 has become a popular regimen in this setting. We conducted a phase III study comparing XELOX with FOLFOX4 in patients who had received prior treatment with irinotecan in combination with bolus and/or infusional 5-FU/LV for MCRC. The primary endpoint of the study was time-to-tumor progression (TTP). With 610 patients, this study had 80% power to detect non-inferiority of the XELOX vs. FOLFOX, defined by a progression hazard ratio (HR) of <1.3. Methods: Patients were treated with XELOX (oxaliplatin 130mg/m2 i.v., capecitabine 1,000mg/m2 bid oral x 14 days, q3w) or FOLFOX4 (as described previously). Results: The study recruited 627 patients (the intent-to-treat - ITT - group). Baseline characteristics were well balanced. The primary objective of the study was met with a progression HR of 0.97 for the XELOX group (95% CI, 0.83–1.14). Median TTP was 4.8 months for XELOX- and 4.7 months for FOLFOX4-treated patients. Overall survival was also similar between the groups with a death HR of 1.03 for the XELOX group (95% CI, 0.87–1.23). Median survival was 11.9 months for XELOX- and 12.6 months for FOLFOX4-treated patients. Grade 3/4 toxicities occurred in 60.1% of XELOX- and 72.4% of FOLFOX4-treated patients. The most common treatment-related grade 3/4 adverse events (XELOX vs. FOLFOX4) were: diarrhea (20 vs. 5%), neutropenia (5 vs. 35%), fatigue (5 vs. 8%), paresthesia (9 vs. 8%), nausea/vomiting (6 vs. 5%). The rate of grade 3 hand-foot syndrome was 3.5% with XELOX and 0.6% with FOLFOX4. The 60-day all cause mortality was 3.9% in XELOX- and 4.2% in FOLFOX4-treated patients. Conclusions: These results demonstrate that second-line treatment with XELOX is non-inferior to FOLFOX4 in terms of PFS. Results for overall survival and response rates were also similar between the two groups. The safety profile was similar to previous studies, with no unexpected toxicities. Study supported by Hoffmann-La Roche. No significant financial relationships to disclose.

4576 Background: RECORD-2 (NCT00719264) primary analysis demonstrated similar median progression-free survival (PFS) for pts with mRCC treated with E+B and I+B (Dec 2011 cut-off). The primary objective was not met; median PFS in E+B/I+B was 9.3/10.0 mo (HRIFN/EVE, 0.91; 95% CI, 0.69-1.19; P=0.485) and probability of success (PoS) of a subsequent phase III trial was 5.1%. Here we present final OS and safety/exposure results (Aug 2012 cut-off). Methods: Untreated pts with clear cell mRCC and previous nephrectomy were randomized 1:1 to B 10 mg/kg every 2 weeks and either E 10 mg/day or I (9 MIU 3 times/week). The primary objective was treatment effect on PFS per central review based on an estimation of PoS (≥50%) of a subsequent phase III study. Secondary objectives included OS and safety. Results: In E+B (n=182) and I+B (n=183) arms, median age was 60/60 years and 76/72% of pts were men, respectively. In both arms, most pts (93%) were of favorable/intermediate MSKCC risk. Median follow-up was 33 mo. In E+B and I+B arms, 51/52% of pts died, respectively. Median OS (95% CI) was 27.1 mo (19.9-35.3) in the E+B arm and 27.1 mo (20.4-30.8) in the I+B arm. After discontinuing study treatment, 64/60% of pts in E+B and I+B arms, respectively, received antineoplastic therapy. Median exposure duration in E+B and I+B arms was 8.5/8.3 mo, respectively; AEs resulted in treatment discontinuation for 23/25% of pts, respectively. The most frequent AEs (%) were stomatitis (63), proteinuria (50), diarrhea (40), hypertension (38), and epistaxis (35) in the E+B arm and decreased appetite (45), fatigue (42), proteinuria (38), asthenia (35), and pyrexia (35) in the I+B arm. The most frequent grade 3/4 AEs (%) were proteinuria (24), stomatitis (11), and anemia (11) for E+B and fatigue (17), asthenia (14), and proteinuria (10) for I+B. Conclusions: OS of E+B and I+B was similar. OS results are consistent with PFS primary analysis. First-line treatment with mTOR inhibitor-based therapy did not impair chance of survival relative to standard therapy. No new safety issues were identified and E+B remained generally well tolerated. Clinical trial information: NCT00719264.

4031 Background: The novel somatostatin analog (SSA) pasireotide has a broader binding profile than currently available SSA (octreotide and lanreotide). Results from a phase III study (NCT00690430) of pasireotide LAR (P) vs octreotide LAR (O) in patients (pts) with NET and disease-related symptoms uncontrolled by the maximum approved dose of available SSA are shown. Methods: Pts (N=110) were randomized and stratified by predominant symptom at baseline (diarrhea [D], flushing [F], or D+F) 1:1 to P (60 mg IM) or O (40 mg IM) q28d. Primary objective was symptom response at month (M) 6. Secondary objectives included tumor response and safety. Progression-free survival (PFS) was an exploratory analysis. Results: 53 and 57 pts were enrolled in the P and O arms when the study was halted due to an interim analysis suggesting futility for symptom response. Baseline characteristics were similar between arms. Majority of primary tumor locations were small intestine (72% and 81% in the P and O arms). Symptom response at M6 was 9/43 (21%) and 12/45 (27%) in the P and O arms, odds ratio 0.73 (95% CI, 0.27-1.97; p=0.53). Median numbers of D/day and F/2 weeks and change in symptom from baseline to M6 are in Table. Hyperglycemia (11% vs 0%), diarrhea (9% vs 7%), and abdominal pain (2% vs 9%) were the most common grade 3/4 AEs in the P vs O arms in the core phase, and 7 (13%) and 4 (7%) pts discontinued due to AEs. Median investigator-assessed PFS was 11.8 months and 6.8 months in the P and O arms (HR=0.46; p=0.045). Conclusions: P and O showed a similar safety profile except for the higher frequency of hyperglycemia in P. Pts on P had PFS 5 months longer than pts on O (investigator assessment), despite no differences in symptom response rates. These results warrant a large phase III trial to clarify the role of P as a therapy for NET. Clinical trial information: NCT00690430. [Table: see text]

TPS4661 Background: Liposomal irinotecan administered with 5-fluorouracil/leucovorin (5-FU/LV) is approved in the USA for metastatic pancreatic ductal adenocarcinoma (mPDAC) following progression with gemcitabine-based therapy. A phase 1/2 study in previously untreated locally advanced/metastatic PDAC showed promising anti-tumor activity with liposomal irinotecan 50 mg/m2 free base + 5-FU 2400 mg/m2 + LV 400 mg/m2 + oxaliplatin (OX) 60 mg/m2 on days 1 and 15 of a 28-day cycle (Wainberg et al. Ann Oncol 2019;30 Suppl 4: SO-005). Herein, we present the design of the phase 3 NAPOLI-3 study investigating the efficacy and safety of this regimen as first-line therapy in patients with mPDAC. Methods: NAPOLI-3 (NCT04083235) is a phase 3, open-label, randomized, global study in adults with histologically/cytologically confirmed pancreatic adenocarcinoma not previously treated in the metastatic setting. Patients are required to have one or more metastatic tumors measurable with computed tomography/magnetic resonance imaging and an Eastern Cooperative Oncology Group performance status score of 0–1. Site activation began in Dec 2019 and enrollment is ongoing. Random allocation (1:1) of 750 patients is planned to liposomal irinotecan + 5-FU/LV + OX (regimen as per phase 1/2 study) or nab-paclitaxel 125 mg/m2 + gemcitabine 1000 mg/m2 on days 1, 8 and 15 in a 28-day cycle. The primary endpoint is overall survival (OS). Secondary endpoints (progression-free survival [PFS] and overall response rate assessed with Response Evaluation Criteria in Solid Tumors v1.1 criteria) will be compared only if the primary endpoint shows superiority for liposomal irinotecan + 5-FU/ LV + OX over nab-paclitaxel + gemcitabine. Safety assessments include adverse-event monitoring. Patients will continue treatment until disease progression, unacceptable toxicity or study withdrawal, and will then be followed for survival every 2 months until death or study end (when all patients have died, withdrawn consent or are lost to follow-up). Clinical trial information: NCT04083235 .

Clinical Trial Information

525 Background: Regional therapies in HCC impact the immune microenvironment and may augment the effects of immune checkpoint inhibitors. Methods: This is a multicenter phase 1 study of NIVO and deb-TACE in unresectable HCC pts (BCLC Stage B) and Child Pugh A cirrhosis (NCT03143270). The primary objective is to assess safety. Secondary objectives include response rate by RECIST v1.1, progression-free and overall survival by Kaplan-Meier methodology, and blood/tumor immune correlates. A 3 + 3 design sequentially evaluates 3 cohorts of differing schedules of NIVO relative to deb-TACE. Deb-TACE (75mg of doxorubicin) is administered on Day 0. NIVO is dosed at 240mg IV every 14 days for 1 year (Cohort 1: NIVO begins day +14 after deb-TACE; Cohort 2, interrupted NIVO dosing begins at Day -28 but is held on the Day 0 then restarted on Day +14; Cohort 3, continuous NIVO dosing begins on Day -28 without interruption). Results: As of July 2019, 9 pts have been treated [median 65 years (range: 54-76), male (89%), viral (44%;1 HBV, 3 HCV), non-viral (56%;2 EtOH, 1 NASH, 2 unknown), prior resection (44%), prior regional therapy (44%), 3 pts in each cohort]. No cases of treatment related liver failure, dose-limiting toxicity, or Grade 5 adverse events (AEs) were observed. Grade ≥3 AEs possibly related to nivolumab, deb-TACE, or both included: transaminase elevation (1 pt: day 1 post TACE resolved in 7 days without treatment; 2 pts: ≥30 days post TACE resolved with steroids between 20-41 days), post-embolization syndrome (1 pt: resolved in 5 days), asymptomatic lipase increase (1 pt: resolved in 14 days), post-procedural groin hematoma (1 pt: resolved in 2 days). All 9 pts were evaluable for efficacy: 2 (22%) confirmed PR and 7 (78%) SD. 4/9 pts remain on study with SD or better—2 pts continue > 18 months post embolization with durable PRs. 12 months OS rate was 71%. Ongoing correlates will be presented at a separate meeting. Conclusions: Nivolumab given at various times relative to deb-TACE appears safe and tolerable. Cohort 3 continues to accrue to provide a better estimate of safety and antitumor activity of the combination. Clinical trial information: NCT03143270.
