4019 Background: Regorafenib (R) has been shown to modulate anti-tumor immunity by different mechanisms including reduction of tumor-associated macrophages (TAMs). Synergy between R and anti–PD-1/PD-L1 antibodies has been shown in pre-clinical models. Methods: This is a single-arm open-label multicentric phase II trial assessing the efficacy and safety of R (160 mg QD 3weeks/4) + Avelumab (A) (10 mg/kg every 2 weeks) combination in non MSI-H mCRC patients (pts). The primary endpoint was the confirmed objective response rate, 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 and C2D1. Results: Between Nov. 2018 and Oct. 2019, 48 pts were enrolled in 4 centers. Median age was 61.8 (range: 26.3-78.7). Median follow-up was: 7.2 months. Median number of previous treatment lines was: 3 (range: 1-7). 41 (87.2%) pts experienced at least 1 dose modification or treatment interruption. The most common grade 3/4 adverse events were palmar-plantar erythro-dysesthesia syndrome (29.8%), hypertension (23.4%) and diarrhea (12.8%). No death was related to the treatment. Among 40 pts who had at least one imaging tumor assessment, 12 (30%) had reduction in tumor burden. Best response was stable disease for 23 pts (57.5%) and progressive disease for 17 pts (42.5%). The median PFS and OS were 3.6 months (CI95%: [1.8 – 5.4]) and 10.8 months (CI95%: [5.9 – NA]) respectively. Baseline tumor samples and paired biopsies were available for 24 and 15 pts respectively. High infiltration by TAMs at baseline was significantly associated with adverse outcome (PFS: 1.9 vs 3.7 months, p=0.045; OS: 4.8 months vs NR, p=0.027). Increased tumor infiltration by CD8+ at C2D1 compared to baseline was significantly associated with better PFS (p=0.011). Combining low TAMs infiltration and low tumor cells to CD8+ T cells distance enabled the identification of a subgroup of pts (n= 6/24, 25%) more likely to benefit from R+A combination: median PFS: 5.3 vs 1.9 months (p=0.037); median OS: NR vs 5.3 months (p=0.02). Conclusions: The R+A combination achieved PFS and OS that compared favourably with historical data of R alone in this clinical setting. High-resolution analysis of tumor samples identified a composite score based on TAMs infiltration and tumor cell to CD8+ T cells distance which could be used as a biomarker in further studies investigating this approach in mCRC pts.

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.

7106 Background: E7389, a synthetic analog of halichondrin B that was isolated from a marine sponge, has broad anti-proliferative activity at nanomolar levels and a unique profile of tubulin interactions. Methods: This is an open-label, single-arm, stratified phase II study of E7389 in patients with measurable, recurrent and/or metastatic NSCLC who progressed during or after platinum-based doublet chemotherapy. E7389 (1.4 mg/m2) was administered as a bolus IV on days 1, 8, and 15 of a 28-day cycle to 72 patients (cohort 1) in stratum I (55 taxane pretreated patients) and stratum II (17 taxane-naive patients) and on Days 1 and 8 of a 21-day cycle (cohort 2), providing an additional 22 patients in stratum I. The primary efficacy endpoint was objective response rate to E7389 monotherapy. Results: As of 9 December 2005, 94 evaluable patients received E7389. Nineteen tumors were classified as squamous cell carcinomas, 39 as adenocarcinomas, and 36 were large cell carcinomas or unclassified. The median number of cycles completed was 3. Fifteen patients completed 6 or more cycles and 75 patients underwent tumor assessments after cycle 2. Major toxicities related to study drug included myelosuppression, nausea, fatigue, dehydration, arthralgias, dyspnea, and peripheral neuropathy. Based on RECIST criteria, 6 partial responses (PR) were observed among 94 evaluable patients (PR rate = 6.4%, 95% CI: 2.8%, 12.8%). For 33 patients the best response was stable disease (SD rate = 35.1%, 95% CI: 25.5%, 45.1%). Disease control rate (PR + SD) was 41.5% (95% CI: 31.4%, 51.7%). For cohort 1, the 12-week progression free survival rate was 57.2%. As of 9 December 2005, median PFS time was 108 days (95% CI = 55, min-max = 1–239+). Cohort 2 is being followed to estimate their 12-week PFS. The correlation of beta tubulin isotype, stathmin, microtubule-associated protein 4 (MAP4) and tau protein mRNA expression with tumor responses is on-going. Conclusions: Based on this data, E7389 has been shown to be safe and effective in the treatment of NSCLC patients. Updated information and results of molecular correlations of responses will be presented. [Table: see text]

8056 Background: E7389 is a structurally simplified synthetic macrocyclic ketone analog of halichondrin B and has a unique mechanism of microtubule binding and interaction, distinct from other agents in this class. Thus, it was our hypothesis that pts with prior taxane based therapy would respond to this agent. We conducted a phase II trial of E7389 in prior taxane-treated NSCLC pts. Methods: Eligible pts included: histologically confirmed advanced NSCLC, previous treatment with platinum-based therapy and a taxane, no more than 2 prior regimens, measurable disease, Zubrod performance status ≤ 2. Pts were classified by taxane-sensitivity status: taxane sensitive (TS) (progression >90 days after taxane) or taxane resistant (TR) (progression during or ≤90 days after taxane). Treatment: E7389 1.4 mg/m2 intravenously over 1–2 minutes on day 1 and 8 of a 21 day schedule until disease progression or unacceptable toxicity. Results: 41 pts were entered. There were 3 (15%) objective responses (7.2+, 8.5+, 10.6 mo) of 20 TS pts; and no response of 21 TR pts. Stable disease rate was 60% and 24% in TS and TR pts. respectively. Median progression free survival (PFS) is 6.3 mos TS pts. 95%CI (2.5–8.6 mos) and 1.2 mos TR pts. 95%CI (1.1–4.1 mos). Median number of cycles (range): TS 4 (1–14); TR 2 (1–7). Major toxicity included: 19 pts (46%) with grade 3 or 4 hematologic toxicity including only 1 episode of febrile neutropenia and 8 pts (20%) with grade 3 or 4 non-hematologic toxicity attributable to drug including: fatigue (1), dehydration (2), nausea (2), constipation (2). Only 1 pt developed grade 3 neuropathy (course 9). Conclusions: E7389 was well tolerated with encouraging objective response, PFS and disease control rate in the TS cohort. This cohort will be expanded, using a 2-stage design, to accrue up to another 25 pts. No significant financial relationships to disclose.

Purpose We performed a phase II study of oral vorinostat, a histone and protein deacetylase inhibitor, to examine its efficacy and tolerability in patients with relapsed/refractory indolent lymphoma. Patients and Methods In this open label phase II study (NCT00253630), patients with relapsed/refractory follicular lymphoma (FL), marginal zone lymphoma (MZL), or mantle cell lymphoma (MCL), with ≤ 4 prior therapies were eligible. Oral vorinostat was administered at a dose of 200 mg twice daily on days 1 through 14 of a 21-day cycle until progression or unacceptable toxicity. The primary end point was objective response rate (ORR), with secondary end points of progression-free survival (PFS), time to progression, duration of response, safety, and tolerability. Results All 35 eligible patients were evaluable for response. The median number of vorinostat cycles received was nine. ORR was 29% (five complete responses [CR] and five partial responses [PR]). For 17 patients with FL, ORR was 47% (four CR, four PR). There were two of nine responders with MZL (one CR, one PR), and no formal responders among the nine patients with MCL, although one patient maintained stable disease for 26 months. Median PFS was 15.6 months for patients with FL, 5.9 months for MCL, and 18.8 months for MZL. The drug was well-tolerated over long periods of treatment, with the most common grade 3 adverse events being thrombocytopenia, anemia, leucopenia, and fatigue. Conclusion Oral vorinostat is a promising agent in FL and MZL, with an acceptable safety profile. Further studies in combination with other active agents in this setting are warranted.

5036 Background: ABT-869 is a novel, orally active and potent inhibitor of all VEGF and PDGF receptor tyrosine kinases. Results from a phase I study suggested antitumor activity in advanced solid tumors including RCC. The recommended dose for phase II investigation was 0.25 mg/kg (maximum 25 mg) daily. Methods: We conducted an open-label, multicenter phase II trial of oral ABT-869 in advanced RCC. Eligibility criteria included progressive disease (PD) within 100 days of enrollment after at least 2 cycles of sunitinib, prior nephrectomy, and adequate organ function. The primary endpoint was objective response rate (ORR) per RECIST by central imaging. Secondary endpoints were best response, time to progression (TTP), progression free survival (PFS), and overall survival (OS). Safety was assessed by NCI-CTCAE, v3.0. Results: 53 patients (pts, median age, 61 y [range, 40–80]; clear-cell histology [41 pts]; median number of prior therapies, 2 [range, 1–4]) were enrolled from 8/07 to 10/08. All pts were previously treated with sunitinib, and additional prior treatments included cytokine (19%), sorafenib (15%), temsirolimus (4%), and bevacizumab (4%). Preliminary efficacy data are shown in the Table below. Median TTP was 4.9 mos [95% CI: 3.5–6.8] per central imaging. Median OS is not estimable. The most common adverse events (AEs) were diarrhea (78%), fatigue (67%), hypertension (53%), nausea (51%) and vomiting (39%). AEs ≥ grade 3 included hypertension (24%), fatigue (18%), diarrhea (14%) and hand-foot syndrome (14%). 39 pts required dose reductions. Of the 20 pts who have discontinued therapy at the time of this analysis, 16 were due to PD, 3 due to AEs (1 hemoptysis, 1 fatigue, 1 fatigue/hypertension) and 1 withdrew consent. The remaining 33 pts continue protocol treatment, and updated results will be presented. Conclusions: ABT-869 has activity in RCC after sunitinib failure. The dose will be optimized for future studies. [Table: see text] [Table: see text]

698 Background: Survival statistics for mPDA are dismal and with limited treatment options novel agents are needed to improve disease outcomes. PBI-05204 (Phoenix Biotechnology, Inc., San Antonio, TX) is a modified supercritical carbon dioxide extract of Nerium oleander leaves. Oleandrin, the extract’s major cytotoxic component, has demonstrated anti-tumor activity in various tumor cell lines. In a human PDA orthotopic model, this preparation reduced tumor burden as monotherapy. Pharmacodynamic studies suggest that PBI-05204’s mechanism of action is through inhibition of the PI3k/Akt/mTOR pathway. Methods: A phase II single-arm, open-label study to determine the efficacy of PBI-05204 in patients (pts) with mPDA refractory to standard therapy was conducted. The primary endpoint was overall survival (OS) with the hypothesis that 50% of pts would be alive at 4.5 months. Secondary objectives included safety, progression-free survival (PFS), and overall response rate. Pts received oral PBI-05204 daily until progressive disease (PD), unacceptable toxicity, or pt withdrawal. Radiographic response was assessed every two cycles. Results: Forty-one pts were enrolled; two never received treatment and one was found to have a neuroendocrine tumor after pathological re-evaluation, leaving 38 pts for analysis. Median age at time of enrollment was 65.0 years. The median time from initial diagnosis to treatment was 16.9 months. The primary reason for withdrawal was PD (45.2%). Ten pts were alive at 4.5 months (26.3%) with a mPFS of 56 days (corresponding to first restaging). One objective response (2.6%) was observed for 162 days. Grade ≥3 treatment-emergent adverse events occurred in 63.2% of pts with the most common attributed to drug (all grades) being fatigue (36.8%), vomiting (23.7%), nausea (18.4%), decreased appetite (18.4%), and diarrhea (15.8%). Conclusions: PBI-05204 did not meet its primary endpoint for OS in this study. Recent preclinical data indicate an efficacious role for PBI-05204 against glioblastoma multiforme when combined with chemotherapy, such as temozolomide, and radiotherapy. A randomized Phase II trial is currently being designed. Clinical trial information: NCT02329717.

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.

Abstract Background Dengue is a global health problem requiring an effective, safe dengue vaccine. Methods We report the results of a phase II, randomized, open-label, single-center trial in adults aged 18 to 45 years in the United States designed to explore the effects of the Chimeric Yellow Fever Derived Tetravalent Dengue Vaccine (CYD-TDV, Dengvaxia) when administered on its designated schedule (months 0, 6, and 12) or on an accelerated dosing schedule (months 0, 2, and 6) and/or given before, or concomitantly with, a vaccine against Japanese encephalitis (JE). Results Based on dengue virus serotype-specific neutralizing antibody (NAb), the accelerated dosing schedule was comparable to the 0, 6, and 12-month schedule. Giving JE vaccine concurrently with CYD-TDV did not result in an increase in overall NAb titers. Immunophenotyping of peripheral blood mononuclear cells revealed an increase in activated CD8+ T cells after CYD-TDV vaccination, a phenomenon that was greatest for the JE vaccine primed. Conclusions We conclude that an accelerated dosing schedule of CYD-TDV results in essentially equivalent dengue serotype-specific NAb titers as the currently used schedule, and there may be an early benefit in antibody titers and activated CD8+ T cells by the administration of the JE vaccine before CYD-TDV vaccination.

Metastatic Urothelial Carcinoma

PURPOSE Patients with metastatic urothelial carcinoma are often ineligible for cisplatin-based treatments. A National Cancer Institute Cancer Therapy Evaluation Program–sponsored trial assessed the tolerability and efficacy of a gemcitabine-eribulin combination in this population. METHODS Patients with treatment-naïve advanced or recurrent metastatic urothelial carcinoma of the bladder, ureter, or urethra not amenable to curative surgery and not candidates for cisplatin-based therapy were eligible. Cisplatin ineligibility was defined as creatinine clearance less than 60 mL/min (but ≥ 30 mL/min), grade 2 neuropathy, or grade 2 hearing loss. Treatment was gemcitabine 1,000 mg/m2 intravenously followed by eribulin 1.4 mg/m2, both on days 1 and 8, repeated in 21-day cycles until progression or unacceptable toxicity. A Simon two-stage phase II trial design was used to distinguish between Response Evaluation Criteria in Solid Tumors, version 1.1 objective response rates of 20% versus 50%. RESULTS Between June 2015 and March 2017, 24 eligible patients with a median age of 73 years (range, 62 to 88 years) underwent therapy. Performance status of 0, 1, or 2 was seen in 11, 11, and two patients, respectively. Sites of disease included: lymph nodes, 16; lungs, nine; liver, seven; bladder, five; bones, two. Median number of cycles received was four (range, one to 16). Of 24 patients, 12 were confirmed responders; the observed objective response rate was 50% (95% CI, 29% to 71%). Median overall survival was 11.9 months (95% CI, 5.6 to 20.4 months), and median progression-free survival was 5.3 months (95% CI, 4.5 to 6.7 months). The most common treatment-related any-grade toxicities were fatigue (83% of patients), neutropenia (79%), anemia (63%), alopecia (50%), elevated AST (50%), and constipation, nausea, and thrombocytopenia (42% each). CONCLUSION Gemcitabine-eribulin treatment response and survival for cisplatin-ineligible patients compare favorably to other regimens. Additional research is needed.

5576 Background: Endometrial cancer (EC) is the most common gynecologic malignancy. Vascular endothelial growth factor (VEGF) overexpression in EC correlates with poor outcome, thus targeting VEGF is a rational therapeutic approach. We have conducted a two-stage open-label phase II study in advanced EC with sunitinib, an oral tyrosine kinase inhibitor of multiple VEGF receptors. Methods: Eligible pts have recurrent or metastatic EC and have received up to 1 prior chemotherapy (CT) regimen for metastatic disease. Sunitinib is given at 50 mg daily (OD) for 4 consecutive weeks (wks) followed by 2 wks off. Dose could be reduced to 37.5 mg OD and then 25 mg OD in the setting of toxicity. Imaging is repeated every 12 wks. Primary objectives are objective response rate (ORR by RECIST) and rate of 6-month progression-free survival (PFS). If 1 or more responses occur in the first 15 evaluable pts, the study would continue to a second stage (total = 30 pts). Secondary objectives are time to progression (TTP), overall survival (OS), and safety. Results: We report the results of the first stage of this study. Sixteen pts have been treated (median age: 63; range 41–74) with 37 cycles of sunitinib (median 2; range: 1–7). Baseline ECOG PS was 0 (7 pts), 1 (8 pts), or 2 (1 pt). Histology was endometrioid (7 pts), serous (5 pts), clear cell (1 pt), or mixed/other (3 pts). Most pts had high-grade histology (G3: 8; G2: 4; G1: 2; GX: 2). Nine pts had prior adjuvant CT, 8 pts had 1 prior CT for advanced EC, 4 pts had prior hormones and 7 pts had prior radiotherapy. Partial response was achieved by 2 pts (ORR = 12.5%), and 2 other pts had a best response of stable disease; 3 of these pts remained progression-free > 6 months. Median TTP = 2.5 months (95% CI: 2.47-NR), and median OS = 6.2 months (95% CI: 5.1-NR). Grade 3/4 adverse events (AE) in >10% of pts were fatigue (7 pts, 44%) and hypertension (5 pts, 31%). Dose reduction was required for 11 of 16 pts (69%). Two pts were inevaluable after receiving <2 cycles due to AE (grade 4 hyponatremia; grade 3 fatigue) and 1 other pt has yet to complete 2 cycles. Conclusions: Sunitinib shows preliminary activity in EC. This trial will proceed to a second stage of accrual to further explore the efficacy and safety of sunitinib in advanced EC.
