4532 Background: Standard first-line regimens for patients with metastatic gastroesophageal adenocarcinomas have moderate clinical benefit with objective response rates (ORR) of approximately 40-50%. FOLFIRINOX has been shown to be an effective and well-tolerated first line therapy in other GI cancers. In this open-label, single-arm phase II study of patients with advanced gastroesophageal adenocarcinomas, we sought to evaluate the safety and clinical activity of FOLFIRINOX. Methods: The primary endpoint was ORR, and secondary endpoints included safety profile, progression free survival (PFS), overall survival (OS), time to progression (TTP), clinical benefit rate (CBR), and duration of response. Estimated sample size included 41 patients with HER2 negative disease with 90% power to detect an ORR≥60% with alpha of 0.10. No enrollment goal was planned for HER2 positive patients, but they were allowed participation to receive study treatment in combination with trastuzumab. Treatment consisted of 400mg/m2 5-FU bolus, 400 mg/m2 leucovorin, 2400 mg/m2 5-FU infusion over 46 hours, 180 mg/m2 irinotecan, and 85 mg/m2 oxaliplatin. Trastuzumab was administered intravenously as a 6 mg/kg loading dose then given 4 mg/kg every 14 days for HER2 positive patients. This trial is registered with ClinicalTrials.gov, NCT01928290. Results: From November 2013 to May 2019, 67 patients were enrolled, of which 26 (39%) had HER2 positive disease. Median follow-up was 16.1 months. ORR was 61% (25/41) for HER2 negative and 85% (22/26) for HER2 positive groups. Overall, one patient (2%) had a complete response, 36 patients (69%) had partial responses, and 13 patients (19%) had stable disease for >6 months; therefore, CBR was 96%. Median PFS was 11.9 months, median OS was 17.4 months. 41 patients (83.7%) had dose modification or treatment delay with the most common toxicities being neutropenia, diarrhea, peripheral sensory neuropathy, and nausea with no unexpected toxicities. Conclusions: FOLFIRINOX is a highly effective three-drug regimen for first-line treatment of advanced gastroesophageal cancer with expected, tolerable toxicities. Clinical trial information: NCT01928290 .

4096 Background: Regorafenib (R) has shown promising efficacy in patients (pts) with BTC refractory to standard chemotherapy. Anti-PD1/PD-L1 antibodies have only limited clinical activity. Synergy between R and anti–PD-1/PD-L1 antibodies has been shown in pre-clinical solid tumor models. Methods: This is a single-arm open-label multicentric phase II trial (Bayesian adaptive design) assessing the efficacy and safety of R (160 mg QD 3weeks/4) + avelumab (A) (10 mg/kg every 2 weeks) combination in BTC pts. The primary endpoint was the objective response rate under treatment, based on central review according to RECIST 1.1. Secondary endpoints included: 1-year progression free survival (PFS), 1-year overall survival (OS), and Safety using NCI-CTCAE v5.0. Correlative studies were planned from pts tumor samples obtained at baseline. Results: Between Nov. 2018 and Nov. 2019, 34 BTC pts were enrolled in 4 centers. Median age was 63 (range 36 – 80). Median follow-up was 9.8 months. Median number of previous treatment lines for metastatic or locally advanced disease was: 2 (range 1 – 4). Twenty-nine (85.3%) pts experienced at least 1 dose modification or treatment interruption of R or A due to an adverse event (AE) related to the treatment. The most common grade 3/4 AEs were : Hypertension (17.6%), Fatigue (14.7%), and maculo-papular rash (11.8%). No death was related to the treatment. Among the 29 pts with at least one imaging tumor assessment, 4 (13.8%) achieved a partial response, and 11 (37.9%) demonstrated stable disease including 10 (34.5%) pts with tumor shrinkage. Fourteen pts (48.3%) had progressive disease. The median PFS and OS were 2.5 months (95%CI 1.9 – 5.5) and 11.9 months (95%CI 6.2 – NA) respectively. Baseline tumor samples were available for 27 pts. High IDO and PD-L1 expression at baseline was associated with better outcome. Conclusions: The R+A combination is associated with significant anti-tumor activity with promising survival rates in this heavily pre-treated population. Full Biomarkers analyses will be presented at the meeting. Clinical trial information: NCT03475953.

TPS143 Background: Patients with KRAS and NRAS ( RAS) wild-type mCRC benefit from the epidermal growth factor receptor (EGFR) monoclonal antibodies (Abs) panitumumab and cetuximab, but nearly all patients experience resistance. Blood-based profiling of cell free DNA (cfDNA) can identify genomic alterations that drive acquired EGFR Ab resistance. After discontinuation of anti-EGFR Abs, acquired genomic alterations decay over time to undetectable levels. Some studies have suggested clinical benefit from EGFR Ab rechallenge, but there is limited evidence that EGFR Ab rechallenge improves survival compared to standard of care (SOC) therapies. We hypothesize that cfDNA profiling will identify patients appropriate for panitumumab rechallenge, and that these molecularly selected patients will have improved survival compared to current SOC therapies. Methods: This is a randomized phase II, open label study designed to compare the overall survival (OS) of panitumumab rechallenge versus SOC (investigator choice TAS-102 or regorafenib). Secondary objectives include comparisons of progression free survival, objective response rate, clinical benefit rate, and quality of life as measured by the linear analogue self-assessment (LASA) questionnaire. Eligible patients have radiographically measurable KRAS, NRAS, and BRAF codon 600 wild-type mCRC based on tumor tissue testing, and must have experienced progression or intolerance to treatment with a fluoropyrimidine, oxaliplatin, irinotecan, an anti-VEGF Ab, and an anti-PD-1 Ab if the tumor has mismatch repair deficiency or is MSI-H. Progression after at least 4 months treatment with an anti-EGFR Ab is required. All patients must be enrolled in the COLOMATE cfDNA screening protocol (NCT03765736) and meet molecular eligibility based on Guardant360 cfDNA profiling (absence of amplification of ERBB2, KRAS, NRAS, and MET; absence of mutations of BRAF, EGFR, ERBB2, KRAS, NRAS, and MET [mutant allele frequency > 0.5%]). Greater than 90 days must have elapsed between the most recent treatment with an anti-EGFR Ab and cfDNA profiling. Dosing for all study drugs is according to clinical SOC. 120 patients will be randomized 1:1 to panitumumab rechallenge or SOC. With 83 OS events, this study will have 80% power to detect an improvement in median OS from 6.5 to 10 months (HR=0.65; 1-sided α= 0.15). This study began enrollment in 6/2020. Recruitment is ongoing at 16 sites in the Academic and Community Cancer Research United (ACCRU) network (ACCRU-GI-1623). Clinical trial information: NCT03992456.

4122 Background: The mammalian target of rapamycin (mTOR) signaling pathway is involved in the pathogenesis of neuroendocrine tumors (NET). Everolimus (RAD001), an oral mTOR inhibitor, has antitumor activity in patients (pts) with advanced NET. In this open-label, multicenter, phase II study (RAMSETE), the safety and efficacy of everolimus monotherapy was evaluated in pts with advanced nonsyndromic, nonpancreatic NET. Methods: Pts with advanced (unresectable or metastatic), progressive, nonsyndromic, nonpancreatic NET received everolimus (10 mg/day) as monotherapy. The primary endpoint was objective response rate (proportion of pts with best overall complete response [CR] or partial response [PR] per RECIST v1.0) by central radiologic review. A secondary endpoint included progression-free survival (PFS). Results: By database soft lock (December 1, 2011), 73 pts from 16 European clinics received everolimus (median duration of treatment: 193 days). Fifty-five (75%) pts discontinued; reasons included disease progression (n=23), adverse events (AEs [n=23]), withdrawal of consent (n=4), death (n=3), and protocol deviation (n=2). In the per protocol population (N=60), 32 (53%) pts received prior antineoplastic therapy. The best response by central review was stable disease in 55%. By local review, 3 (5%) pts had a PR, with SD in 39 (65%) pts. Median PFS by central review was 185 days (95% CI: 158-255). Median PFS by local investigator review was 285 days (95% CI: 231-not estimable). 69 (95%) pts reported treatment-related AEs of any grade, including rash (n=28; 38%), diarrhea (n=20; 27%), mucosal inflammation (n=18; 25%), and decreased appetite (n=17; 23%). Treatment-related grades 3 and 4 AEs and serious AEs were reported by 27 (37%) and 18 (25%) pts, respectively. Conclusions: In this open-label trial of everolimus in pts with advanced, nonsyndromic, extrapancreatic NET, a high rate of disease stabilization was achieved after prior tumor progression with favorable median PFS. This study further supports efficacy of everolimus in types of NET other than those studied in RADIANT-3 (pancreatic NET) and RADIANT-2 (NET associated with carcinoid syndrome).

1002 Background: P is approved for treatment of HR+/HER2− mBC combined with ET. There is paucity of clinical data of single-agent P in ET resistant pts. Pre-clinical data suggest P may partially reverse endocrine resistance, though this is yet to be tested in pts. Methods: This Phase II, open-label, multicenter study enrolled post-menopausal pts with HR+ HER2− mBC who progressed on 1 or 2 prior ETs. Pts were randomized to P (125 mg/d 3 w on/1 w off) alone or to continue their current ET (aromatase inhibitor or fulvestrant) in combination with P (same schedule as P arm). The primary endpoint was clinical benefit rate (CBR) [complete response (CR), partial response (PR) and stable disease (SD) for > 6 months (mo)]. Secondary endpoints were adverse events (AE) and additional measures of efficacy. A two-stage optimal design assessed treatment activity in each arm assuming activity as CB≥40% (α and β = 10%). Exploratory comparisons were planned for safety and efficacy endpoints. Results: 115 pts were enrolled (ITT population) 58 in the P arm and 57 in the P+ET arm. In both arms, 67% of pts had the study treatment as second line ET, 33% as third line, and about 1/3 of pts also received 1 prior chemotherapy for mBC. CBR was similar in both arms: 54% (95% CI 42 - 67%) with P+ET, and 60% (95% CI 48 -73%) with P alone. Median duration of CB was longer with P+ET (11.5 mo; 95% CI 8.6 – 17.8) than with P (6 mo; 95% CI 3.9 - 9.9) (HR 0.31, 95% CI 0.1 - 0.7, p-value 0.001, exploratory). Objective response rate (ORR; CR, PR) was 11% (95% CI 3 - 19%) and 7% (95% CI 0.4 -13%) with P+ET and P, respectively. PFS was 10.8 mo (95% CI 5.6 - 12.7) with P+ET and 6.5 mo (95% CI 5.4 - 8.5) with P alone (HR 0.69, 95% CI 0.4 - 1.1, p-value 0.13, exploratory). AEs were in line with previous data. Conclusions: Single agent P has clinical activity in ET pre-treated HR+/HER2– mBC pts. The observed increase in PFS and duration of CB with P+ET may suggest that P could reverse resistance to the prior line of ET. Translational studies are ongoing to explore potential biomarkers in this setting. Clinical trial information: NCT02549430.

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.

The Impact

BackgroundTrastuzumab is a HER2-trargeted humanized monoclonal antibody that has been studied as a first-line treatment for patients with HER2-positive advanced gastric cancer (AGC). The effect of anti-HER2 therapy according to tumor mutational burden (TMB) in HER2-positive AGC remains unclear.MethodsWe performed next-generation sequencing (NGS), including TMB analysis, in 31 HER2-positive AGC patients with trastuzumab plus chemotherapy as first-line therapy for recurrent (n=8) or metastatic (n=23) tumors. The TruSight Oncology 500 Assay from Illumina (San Diego, CA, USA) was used to evaluate TMB.ResultsAmong 31 patients, 30 had tumors with immunohistochemistry (IHC) 3+, and one was IHC 2+ and silver in situ hybridization (SISH) positive. The median age was 57.0 years old (range, 35-76), and the majority had tumors with low TMB (87.1%, n=27/31). Only four (12.9%) had tumors with high TMB. Of these four, three achieved complete response (CR) or partial response (PR) to treatment, and the remaining patient was not evaluable for tumor response. Objective response rate (ORR) to trastuzumab plus chemotherapy showed a favorable trend in patients with high TMB (75.0%, n=3/4) compared to patients with low TMB (59.3%, n=16/27) (P=0.546). The median progression-free survival (PFS) was not reached in the TMB-high group but was 8.0 months (95% CI, 7.6-8.5) in the TMB-low group (P=0.019)ConclusionThe status of TMB could be a novel biomarker in predicting the efficacy of trastuzumab plus chemotherapy in HER2-positive AGCs.

Gastroesophageal Junction Adenocarcinoma

228 Background: Gastric and esophageal adenocarcinomas are a leading cause of cancer death worldwide. Many of these patients (pts) present with locally advanced unresectable or metastatic disease and are treated with combination cytotoxic chemotherapy. Single agent P is FDA approved for patients with recurrent locally advanced or metastatic gastric or gastroesophageal junction adenocarcinoma (GEJ) whose tumors have a combined positive score (CPS) ≥ 1 after disease progression on or after two lines of therapy including fluoropyrimidine and platinum and her2/neu-targeted therapy (if indicated). More effective therapy is needed earlier in the disease trajectory. We conducted a single-arm phase II trial to establish the safety and efficacy of first-line C and O + P. Methods: Pts with previously untreated metastatic GE adenocarcinoma regardless of PDL-1 status received intravenous (IV) P 200mg with IV O 130mg/m2 every three weeks and oral C 850mg/m2 twice daily for 14 days on/7 days off. After the 6 patient safety cohort, pts first completed a biomarker cycle that included fresh tumor biopsy before P and one week after P before chemotherapy started. Archived FFPE tumor samples were also obtained from all pts with available tissue. The primary endpoint was progression free survival (PFS); secondary endpoints included response rate (RR) and overall survival (OS). Results: 36 pts were enrolled and 34 pts were evaluable for efficacy (1 pt withdrew for personal reasons before end of cycle 1 and 1 pt had immune-related toxicity during cycle 1 and was taken off study before any efficacy assessment). 9 pts (26%) had an esophageal primary, 18 pts (53%) had a GEJ primary and 7 pts (21%) had a gastric primary. Median PFS was 7.6 months [95% CI: 5.8 to 12.2], RR was 72.7% [95% CI: 57% to 88%], and median OS was 15.8 months [95% CI: 11.6 to NE]. 27 patients (81.8%) had decrease in disease burden (ranging from -19% to -100%). After > 18 months of follow-up, 5 patients remained in durable complete response (CR). Immune-mediated treatment related adverse events (TRAEs) included thyroid disorders (n=5; 14%), colitis (n=4; 11%), adrenal insufficiency (n=2; 5%), and type 1 diabetes (n=1). Sixteen patients (44%) experienced grade 3 or 4 TRAEs. There were no grade 5 TRAEs. Conclusions: The combination of C and O + P had acceptable safety and significant clinical activity. These promising results indicate that C and O + P merits further study as a first line option for patients with unresectable locally advanced or metastatic GE adenocarcinoma. Updated survival and correlative data will be presented. Clinical trial information: NCT03342937.

Purpose The prognosis for women with recurrent and metastatic endometrial cancer is poor, and improved therapies are needed. The mammalian target of rapamycin (mTOR) pathway is an important target, and mTOR inhibitors show clinical activity in endometrial cancer. Patients and Methods An open-label, multicenter, randomized, phase II trial of oral ridaforolimus compared with progestin or investigator choice chemotherapy (comparator) was undertaken in women with metastatic or recurrent endometrial cancer who had progressive disease following one or two lines of chemotherapy and no hormonal therapy. The primary end point was progression-free survival (PFS) assessed by independent radiologic review. Results One hundred thirty patients were enrolled (64 received ridaforolimus and 66 received the comparator), and median age was 66 years. Treatment discontinuation as a result of adverse events was 33% with ridaforolimus versus 6% with the comparator, with common (> 10%) grade 3 toxicities being hyperglycemia, anemia, and diarrhea. Thirty-eight percent (ridaforolimus) versus 71% (comparator) of patients discontinued treatment as a result of disease progression. Median PFS at the protocol prespecified interim analysis with 58 PFS events (primary end point) was 3.6 months (95% CI, 2.7 to 7.3 months) for ridaforolimus and 1.9 months (95% CI, 1.9 to 2.3 months) for the comparator (hazard ratio, 0.53; 95% CI, 0.31 to 0.90; P = .008). PFS rate for ridaforolimus versus comparator was 48% versus 18% at 16 weeks and 38% versus 15% at 24 weeks. Objective response rate for ridaforolimus versus comparator was 0% versus 4% (P = .925), and stable disease was achieved in 35% versus 17% of patients (P = .021). Conclusion Oral ridaforolimus shows encouraging activity in advanced endometrial cancer but is associated with significant toxicity. Inhibition of the PI3K/Akt/mTOR pathway may be a viable therapeutic target.

7541 Background: AFL is a recombinant human fusion protein that acts as a decoy receptor and prevents the interaction of vascular endothelial growth factor (VEGF)-A, VEGF-B, and placental growth factor with their receptors. This study evaluated the efficacy and safety of AFL in combination with first-line chemotherapy of C and P in NSCLC. Methods: This phase II, single arm, open label, multicenter trial in patients with previously untreated, locally advanced, or metastatic NSCLC excluded patients with squamous histology, cavitating lesions, ECOG > 1, uncontrolled hypertension, or brain/CNS metastases. All patients received IV AFL 6 mg/kg, P 500 mg/m2, and C 75mg/m2, every 3 weeks for up to 6 cycles. For those who completed the combined chemotherapy, Q3W administration of AFL was to continue until disease progression, intolerable toxicity, or any other cause for withdrawal. The primary endpoints were objective response rate (ORR) and progression free survival (PFS). Planned sample size was 72 patients. Results: The study was closed prematurely due to 3 confirmed cases of reversible posterior leukoencephalopathy syndrome (RPLS). A total of 42 patients were enrolled. Median age was 61.5 years; 54.8% were male, 85.7% white and 50% ECOG 0. A median of 4 cycles of AFL was administered. The most common treatment-emergent adverse events (TEAEs) of any grade were nausea (69%) and fatigue (67%), with hypertension (36%) as the most common grade 3/4 TEAE. The 3 patients with RPLS were Caucasian women. Two had a history of hypertension and both experienced elevated BP and reduced CrCl. Of the 38 patients evaluable for response, ORR was 26.3% (95% CI, 12.3-40.3%) and median PFS was 5 months (95% CI, 4.3-7.1). Conclusions: The rate of RPLS observed in this study with AFL + C + P was higher than anticipated. A meta-analysis of safety from three large placebo-controlled studies reported no RPLS among 1333 patient treated with AFL + chemotherapy, and none was reported in prior combination studies of AFL + P or AFL + C + docetaxel. Though the study was stopped early, ORR and PFS were in accordance with most historical first-line NSCLC studies.

TPS482 Background: Two combination chemotherapy regimens have emerged as standard of care options for first-line treatment of mPAC: 5-fluorouracil (5-FU)/leucovorin (LV) + irinotecan + oxaliplatin (FOLFIRINOX), and nab-paclitaxel + gemcitabine. Nal-IRI (MM-398) is a nanoliposomal formulation of irinotecan. In a randomized phase 3 study (NAPOLI-1), of patients with mPAC who had been previously treated with gemcitabine-based therapy, nal-IRI + 5-FU/LV demonstrated its safety and significant clinical activity, increasing overall survival (OS) and progression-free survival (PFS) relative to 5-FU/LV. The goal of this current study is to determine the preliminary safety and efficacy of nal-IRI+ + 5-FU/LV with or without oxaliplatin as compared to nab-paclitaxel + gemcitabine in previously untreated patients with mPAC. Methods: This open-label, phase 2 comparative study will be conducted in two parts. Part 1 is a safety run-in of a nal-IRI+5-FU/LV + oxaliplatin regimen. The safety run-in will enroll small cohorts of patients following a traditional 3 + 3 dose escalation design to confirm the target dose of oxaliplatin (n = ~6-18). The primary objective of Part 1 is the safety and tolerability of nal-IRI + 5FU/LV + oxaliplatin. Part 2 is a randomized, efficacy study of a nal-IRI + 5-FU/LV + oxaliplatin regimen (Arm 1), the nal-IRI + 5-FU/LV combination that previously demonstrated efficacy in the NAPOLI-1 trial (Arm 2), versus a nab-paclitaxel + gemcitabine control arm (Arm 3) (n = ~156-168). The primary objective of Part 2 is to assess the efficacy of nal-IRI-containing regimens in first-line mPAC patients compared to nab-paclitaxel + gemcitabine using the progression-free survival (PFS) rate at 24 weeks as the primary endpoint. Secondary of part 1 is a PK study and Part 2 secondary endpoints will include OS, PFS, objective response rate (per RECIST, v1.1), decrease in CA19-9 levels and quality of life assessments. Clinical trial information: NCT02551991.
