419 Background: RAM + DOC in RANGE (NCT02426125) improved progression free survival (hazard ratio [HR] = 0.757) with a higher objective response rate (24.5% vs 14%) and an acceptable safety profile (Petrylak, et al Lancet 2017). QoL was a secondary objective. Methods: Patients (pts) whose UC progressed following platinum-based therapy were randomized to receive RAM (10 mg/kg) + DOC (75 mg/m2) or P + DOC on Day 1 of a 21-day cycle. Treatment continued until disease progression or unacceptable toxicity with a maximum of 10 cycles for DOC. Pts completed the EORTC QLQ-C30 (v3) prior to each cycle & at the 30-day follow up visit. QoL scales were analyzed for: 1) rates of improved/stable scores (compared with Fisher’s exact test) & 2) time to sustained deterioration (TtD), defined as randomization to first worsening with no subsequent non-worsened assessment (compared with unstratified log-rank test). A ≥10 point change (on 100-point scale) was deemed clinically meaningful. Results: 530 pts were randomized. 254/263 (97%) RAM-DOC & 260/267 (97%) P-DOC pts provided baseline (BL) QoL data & ≥85% for post-BL, on-therapy assessments. Median number of cycles was 4 for RAM-DOC & 3 for P-DOC. Mean BL scores were similar between arms & indicated greatest impairment for global QoL, fatigue, pain, & insomnia. For all scales, rates of improved/stable scores were not different, except for pain at Cycles 4 & 7 where rates were higher for RAM-DOC (p < 0.05). Relative to other QoL scales, pain generally had highest rates of improved scores in both arms (14-25% for RAM-DOC & 8-24% for P-DOC for Cycles 1-4). In a post hoc analysis, Cycles 1-4 rates of improved pain scores were 31-32% for RAM-DOC & 14-26% for P-DOC in tumor responders, but 17-29% for RAM-DOC & 16-28% for P-DOC in pts with stable disease. For TtD, 14/15 QoL scales had HRs < 1, indicating similar or numerically longer TtD in QoL for RAM-DOC (HRs 0.67- 1.06; all 95% confidence intervals included 1). Conclusions: The addition of RAM to DOC for platinum-refractory UC pts did not adversely impact QoL relative to P-DOC. Trends in improved TtD and improved rates of pain associated with tumor response favored RAM-DOC. Clinical trial information: NCT02426125.

415 Background: Immune checkpoint inhibitors (ICI) have been approved in solid tumors with dMMR. However, only limited data are available for PDAC with dMMR given the rarity of dMMR in PDAC. We evaluated efficacy of ICIs in PDAC with dMMR. Methods: Retrospective clinical and pathologic data were collected for patients (pts) with pancreatic adenocarcinoma from May 2017 to June 2020 at Moffitt cancer center. Results: We identified 10 pts with dMMR PDAC. The median age was 64.5 years (range: 42-86) and 4 pts were male. 4 pts had resectable disease, 3 had locally advanced and 3 had metastatic disease at initial diagnosis. MSH6 deficiency (def) was found in 2 cases, PMS2 def in 2, MLH/PMS2 def in 5, and MSH2/MSH6 in 1. 7 pts were treated with ICIs. 3 pts had locally advanced and 4 had metastatic disease when they started ICIs. 5 received Pembrolizumab (pem), 1 received ipilimumab/ nivolumab (ipi/nivo), and 1 received pem then ipi/nivo after progressive disease (PD) on pem. The median number of prior lines of chemotherapy was 1 (range 0-2). 6 pts were evaluable, and 1 had rapid disease progression after 1 dose of pem. Among 6 evaluable pts, 3 had an objective response (1: complete response and 2: partial response), and 2 had stable disease (SD). Median progression-free survival was 8.2 mo, and median overall survival was not reached with median follow-up (FU) of 6.8 mo. The median duration of response was not reached with a median FU of 22.6 mo. The pt with CR remained disease-free for up to 22 months. The pt whose treatment was switched to ipi/nivo after PD on pem achieved SD > 4mo on ipi/nivo. While on immunotherapy, one patient with ipi/nivo developed immunotherapy associated rash requiring systemic steroids, and another on pem developed hypothyroidism requiring levothyroxine. Conclusions: This series suggest ICIs can provide durable clinical efficacy in pts with dMMR PDAC.

341 Background: Neutrophilia is known to be associated with worse prognosis in metastatic renal cell carcinoma (mRCC); however, less is known about the role of eosinophils in the response to immunotherapy (IO). We investigated the association of the baseline neutrophil to eosinophil ratio (NER) with outcomes to IO-based combination treatment in mRCC. Methods: Patients with mRCC treated with ipilimumab plus nivolumab, pembrolizumab plus axitinib, or avelumab plus axitinib at the Vanderbilt-Ingram Cancer Center were retrospectively identified. Patients on >10mg prednisone and patients with prior IO were excluded. Baseline NER (at time of first IO) and association with progression free survival (PFS), overall survival (OS), and objective response rate (ORR) were investigated. Data cutoff was 9/1/2020. Analysis for PFS and OS was performed using the log-rank test and Mantel-Haenszel method, and analysis of the odds ratio for ORR was performed using Fischer’s exact test. Results: Sixty-one patients were identified: 89% clear cell histology, 74% prior nephrectomy, 69% IMDC intermediate risk, and 72% treatment-naïve. Patients with baseline NER < median (N=31) had improved clinical outcomes compared to patients with baseline NER > median (N=30) (Table). Improvement in PFS by NER was maintained when stratified by anti-PD-1/CTLA-4 and anti-PD(L)-1/VEGF (p= 0.0062 and p= 0.049); however, differences in OS and ORR were no longer significant. The median baseline NER among patients with partial response (PR) was significantly lower at 22.7 (95% CI 18.9-31.1) vs. 51.6 (95% CI 39.5-93.1) among those with progressive disease (PD) (p= 0.0054). For comparison, the median neutrophil to lymphocyte ratio was not significantly different between PR (2.60) and PD (3.84, p= 0.056). Conclusions: Patients with a low baseline NER treated with IO-based combinations had improved clinical outcomes compared to patients with a high baseline NER. Additional investigation of this parameter in larger cohorts is warranted. [Table: see text]

e14531 Background: We have previously reported that biweekly gemcitabine-based therapy was active in pretreated mCRC pts (De la Cruz et al, ASCO GI 2008, abstr 377). We aimed to investigate whether germ line polymorphisms may be predictors of clinical outcome in mCRC pts treated with this combination. Methods: We evaluated SNPs of genes involved in gemcitabine metabolism (CDA, dCDK, RRM1, DCTD, SLC28A1), DNA repair (XRCC1, XRCC 3, ERCC1, XPD) and two IgG Fcγ R polymorphisms (Fcγ RIIa- H131R and Fcγ RIIIa-V158F), reported to be predictive of cetuximab-based therapy, even in K-ras mutated pts. Whole blood was collected and DNA extracted from peripheral lymphocytes using a DNA isolation Kit (Qiagen, CA). Polymorphisms were detected using the TaqMan genotyping assays (Applied Biosystems, CA). Clinical response was evaluated according to RECIST criteria. Univariate analysis (Fisher´s exact test for response; log-rank test for TTP and OS) was performed to examine associations between polymorphisms and clinical outcome. Results: Blood samples of 35 out of 39 enrolled pts were tested for genomic analysis. Patient‘s characteristics are as follows; M/F: 26/13, median age: 59 years, median number of prior chemotherapy lines: 2 (1–4), Köhne risk groups; low: 8 pts, intermediate: 18 pts, high: 13 pts. After a median follow-up of 20 months, median progression-free survival (PFS) is 6.7 months (95% CI; 5.2–8.3) and median overall survival 15.4 m (95% CI; 14.7–16.1). Overall response rate (ORR) was 53.8%. RRM1 R284R SNPs (p=0.06), T741T (p=0.02) and RRM1–524CT (p=0.04) were linked to clinical responsiveness. All pts possessing 2 or 3 favourable RRM1 SNPs responded. ORR was 53.3% for pts with no favourable SNPs versus 85% for pts with any favourable SNP (p=0.04). ORR was also significantly higher in pts with any histidine allele in the Fcγ RIIa polymorphism (93% vs. 60%, p=0.034). Median PFS was adversely affected in pts harbouring no favourable RRM1 SNPs (4.2m versus 6.7 months, p=0.019) and in those pts with homozygous Fcγ RIIa-131R allele (4.4 vs. 7.5 months, p=0.007). Conclusions: Polymorphic variants of RRM1 and Fcγ RIIa may play a key role in the efficacy of gemcitabine and cetuximab-based therapy for mCRC pts. No significant financial relationships to disclose.

426 Background: In an open-label, phase IV study of sunitinib as 1st-line treatment (Tx) in Chinese pts with mRCC, median progression-free survival (PFS) and overall survival (OS) were 61.7 and 133.4 wk, respectively; objective response rate (ORR) was 31.1% (Ann Oncol 2012;23:851P). We retrospectively investigated correlations between on-Tx hypertension (HTN), neutropenia (N), and thrombocytopenia (T) and efficacy endpoints in pts from this trial. Methods: HTN was defined by either maximum systolic blood pressure ≥140 mm Hg (S-HTN) or maximum diastolic blood pressure ≥90 mm Hg (D-HTN). Using CTCAE assessment, N grade ≥2 and T grade >1 were used as cut-points for the analyses. Median PFS and OS were estimated by Kaplan−Meier method. The log-rank test was used to compare PFS and OS between groups with and without HTN, N grade ≥2, or T grade >1. Fisher’s exact test was used for ORR. Results: 102 pts were included in the HTN analyses, 60% with S-HTN versus 40% without S-HTN. Pts with S-HTN had greater ORR and longer PFS and OS than pts without S-HTN (Table). (Results were similar with D-HTN; see Table.) 103 pts were included in the N and T analyses, 67% with N grade ≥2 versus 33% with N grade <2, and 56% with T grade >1 versus 44% with T grade ≤1. Pts with N grade ≥2 had significantly greater ORR and significantly longer PFS and OS than pts with N grade <2 (Table). Pts with T grade >1 had greater ORR and significantly longer PFS and OS than pts with T grade ≤1 (Table). Conclusions: The developments of N grade ≥2 and T grade >1 during Tx with sunitinib were significantly associated with better outcome. Median PFS was more than twice as long for pts with S-HTN as for those without S-HTN, but the association did not reach statistical significance. [Table: see text]

631 Background: Sunitinib remains an important treatment option for mRCC, but the effect of comorbidities/comedications on sunitinib treatment outcomes have not been fully explored. Methods: Data were collated from STAR-TOR, an ongoing real-world registry. Cutoff date for analysis was 19 June 2019. This subgroup analysis assessed the presence or absence of hypertension (HTN), and the use or non-use of statins and proton pump inhibitors (PPIs), determined at the time of entry to the registry. Treatment endpoints were overall survival (OS), progression-free survival (PFS) and objective response rate (ORR). OS and PFS were analyzed by Kaplan-Meier methods. Differences within subgroups were tested using Log-rank test for OS and PFS, and Fisher’s exact test for ORR. Results: 557 sunitinib-treated pts were analyzed; 366 had HTN and 191 did not, 130 used statins and 427 did not, and 165 used PPIs and 392 did not. Median (m) OS (95% confidence intervals) was similar in pts with and without HTN (25.4 [21.1, 31.5] vs 21.5 [15.2, 28.0] months; p = 0.215). mPFS (8.0 [6.5, 9.9] vs 6.3 [5.4, 8.2] months; p = 0.140) and ORR (31.2% vs 30.9%; p = 1.000) were also similar in pts with and without HTN. mOS was similar in pts who used statins vs those who did not (27.8 [20.2, 35.4] vs 24.0 [19.4, 27.3] months; p = 0.884), while mPFS was significantly longer in pts who used statins (9.4 [6.5, 13.6] vs 6.9 [5.7, 8.2] months; p = 0.044). ORR was 37.8% vs 29.0% in pts who did and did not use statins (p = 0.072). mOS was significantly shorter in pts who used PPIs vs those who did not (20.2 [14.9, 28.3] vs 25.7 [22.7, 33.0] months; p = 0.021). mPFS (5.8 [4.6, 8.2] vs 8.0 [6.5, 9.8] months; p = 0.091) and ORR (26.6% vs 33.0%; p = 0.177) were similar in pts who did and did not use PPIs. Conclusions: In sunitinib-treated pts with mRCC in a real-world registry, mPFS was significantly longer and there was a trend toward better ORR in pts who used statins, whereas mOS was significantly shorter and there was a trend toward shorter mPFS in pts who used PPIs. Common comedications may affect sunitinib treatment outcomes in pts with mRCC.

Purpose The role of systemic chemotherapy in the management of pancreatic endocrine carcinoma (islet cell carcinoma; PEC) is an area of considerable controversy. Response rates ranging from 6% to 69% have been reported for streptozocin-based chemotherapy. We retrospectively studied 84 patients with locally advanced or metastatic PEC who had been treated with fluorouracil, doxorubicin, and streptozocin (FAS) to determine the objective response rate, duration of progression-free survival (PFS), and duration of overall survival (OS). Patients and Methods Eligible patients had histologic or cytologic confirmation of their tumor and measurable disease on computed tomography or magnetic resonance imaging scans. Response to treatment was evaluated in this study using the new international criteria proposed by the Response Evaluation Criteria in Solid Tumors Committee. Results Sixty-one of the patients were male and 23 were female, with a median age of 54 years (range, 24 to 78 years). The response rate (RR) to FAS was 39%, with a median response duration of 9.3 months. The 2-year PFS rate was 41%, and the 2-year OS rate was 74%. The extent of liver metastatic disease correlated with a worse PFS (P = .01 by log-rank test) and a worse OS (P < .0001 by log-rank test). Analyses showed that metastatic replacement of more than 75% of the liver and prior chemotherapy were independently associated with inferior PFS. Conclusion Patients with locally advanced or metastatic PEC who are treated with FAS may have a reasonable RR, and responders may experience longer PFS and OS. The volume of metastases in the liver is the most important predictor of outcome.

TPS11568 Background: GastroIntestinal Stromal Tumors (GIST) are paradigmatic models of cancers with a driver mutation of an oncogene, in which imatinib is recommended as adjuvant therapy or treatment of locally advanced and metastatic forms. After failure of imatinib (either progression or toxicity), sunitinib and regorafenib are indicated as 2nd and 3rd lines, respectively. Beyond approved drugs, tyrosine kinase inhibitors (TKI) can bring clinical benefit because some clones remain sensitive to TKI. Lenvatinib is a broad spectrum TKI targeting KIT, RET, PDGFRA, VEGFR 1-3 and FGFR 1-4, that is approved in the treatment of differentiated thyroid carcinoma and metastatic renal cell carcinoma and hepatocellular carcinoma. Methods: This prospective, randomized, placebo-controlled, double-blinded, multicenter trial evaluates the efficacy and safety of Lenvatinib in adult GIST patients (pts) who failed at least to previous imatinib and sunitinib. Seventy-four pts will be randomly allocated in a 1:1 ratio to receive either oral lenvatinib, at a daily dose of 24mg, or its matching placebo, continuously, until progression of disease (PD) or unacceptable toxicity. Randomization will be stratified according to the number of different previous anticancer drugs (2 or > 2). The primary objective is to compare the Progression-free survival (PFS) between arms. The expected median PFS are 1.5 month in the control arm and 3.0 months in the experimental arm (HR = 0.5). Seventy one events will provide 90% power to show significant improvement in PFS, using a 2-sided log-rank test at a 10% level. Secondary endpoints include the overall survival, the objective response rate, the best overall response, the quality of life and the safety profile. Patients allocated in the placebo arm who experience PD (RECIST 1.1) may switch to active lenvatinib. Radiological endpoints will be evaluated using the RECIST 1.1. Translational objectives will be to identify blood and tumor parameters as predictive markers of lenvatinib efficacy. Recruitment has been activated in January 2020. Ten participating sites of the French Sarcoma Group will participate in the trial. Clinical trial information: NCT04193553 .

9546 Background: KEYNOTE-629 is a single-arm phase 2 study of pembro for cSCC. At second interim analysis (IA), pembro had robust and durable antitumor activity and manageable safety in LA and R/M cohorts. At first IA, pembro maintained HRQoL in the R/M cohort; LA was not analyzed because of ongoing accrual. HRQoL of pts with LA or R/M cSCC at second IA (database cutoff July 29, 2020; additional 15-mo follow-up since IA1 for the R/M cohort) is shown. Methods: Pts with LA or R/M cSCC received pembro 200 mg IV Q3W for ≤35 cycles. HRQoL was a prespecified exploratory end point assessed using EORTC QLQ-30 and EuroQol EQ-5D-5L instruments administered at baseline, wk 3, and wk 6; then Q6W through y 1; then Q9W until treatment end/discontinuation; and at the 30-day safety follow-up. HRQoL was analyzed in pts who received ≥1 pembro dose and completed baseline and ≥1 postbaseline HRQoL assessments. Mean change from baseline in EORTC QLQ-C30 global health status (GHS)/quality of life (QoL), physical functioning (PF), and EQ-5D-5L visual analog scale (VAS) scores were evaluated at wk 12 to ensure adequate completion rate and through last pt visit at wk 75 for EORTC QLQ-C30 GHS/QoL and PF scores. HRQoL was categorized as improved or deteriorated based on ≥10-point change in EORTC QLQ-C30 scores (considered clinically meaningful). Results: The HRQoL analysis population for LA had 47 pts for EORTC QLQ-C30 and EQ-5D-5L; the R/M cohort had 99 pts for EORTC QLQ-C30 and 100 for EQ-5D-5L. At wk 12, compliance rates were >75% for LA and >80% for R/M cohorts for EORTC QLQ-C30 and EQ-5D-5L. Mean change from baseline to wk 12 was minimal for EORTC QLQ-C30 GHS/QoL, PF, and EQ-5D-5L VAS scores for both cohorts (Table). Mean change from baseline in EORTC QLQ-C30 GHS/QoL and PF scores remained stable over 48 wk in the LA cohort (75-wk data unavailable) and over 75 wk in the R/M cohort. Most pts had improved or stable EORTC QLQ-C30 GHS/QoL and PF scores relative to baseline during follow-up. Conclusions: HRQoL was generally maintained with pembro in LA and R/M cSCC cohorts and was not negatively impacted by tumor progression or AEs. Clinical trial information: NCT03284424.

1020 Background: In the MONALEESA-2 trial, ribociclib + letrozole significantly improved progression-free survival (PFS) and showed higher overall response rates vs letrozole alone in HR+, HER2– ABC. To place these clinical results in the context of patient experience, here we present key patient-reported outcomes (PROs) including HRQoL. Methods: 668 patients were randomized (1:1); 334 each to the ribociclib + letrozole and placebo + letrozole arms. PROs were evaluated during treatment and at progression using the EORTC QLQ-C30, QLQ-BR23, and EQ-5D-5L questionnaires. Changes from baseline in all subscales were analyzed using a linear mixed-effect model and time to 10% deterioration was compared between treatment arms using the stratified log-rank test. Results: Questionnaire compliance rates were high (≥90%). During treatment, HRQoL (global health status/QoL score) was maintained and similar in both treatment arms. At progression/end of treatment, HRQoL worsened numerically in both arms. Time to definitive 10% deterioration of HRQoL was similar between treatment groups, slightly favoring the ribociclib + letrozole arm (hazard ratio: 0.89; 95% confidence interval: 0.67–1.18). No statistically or clinically relevant differences were observed for key symptoms using EORTC QLQ-C30 including fatigue, nausea, and vomiting. There was a clinically relevant ( > 5 points) improvement in pain from baseline to post-baseline (up to Cycle 15) in the ribociclib + letrozole arm while there was only mild improvement ( < 5 points) observed in the placebo + letrozole arm. Conclusions: In addition to significantly improving PFS, ribociclib + letrozole maintains HRQoL when compared with letrozole + placebo. A numerical trend was observed favoring ribociclib + letrozole for pain reduction. Clinical trial information: NCT01958021.

4639 Background: FOLFIRINOX (5FU, irinotecan, and oxaliplatin) is a reference first line (L1) of chemotherapy (CT) in fit patients (Pts) with advanced pancreatic cancer (aPC). Limiting toxicities (in particular, neuropathy) are frequent and maintaining quality of life without a lack of efficacy is a crucial need. Modalities and efficacy of maintenance strategy in aPC remain scarcely studied. Our study describes the French practices of a FOLFIRINOX de-escalation and maintenance in a real-life multicentric cohort. Methods: We performed a retrospective multicentric study in 5 French centers. Pts receiving FOLFIRINOX L1 for aPC were recruited between January 2011 and December 2018. FOLFIRINOX de-escalation was defined as stopping oxaliplatin and/or irinotecan in patients without tumor progression, after at least 4 cycles of FOLFIRINOX. Maintenance schedules were oral capecitabine or intravenous (IV) 5FU, FOLFOX or FOLFIRI. Primary endpoint was overall survival (OS). Secondary endpoints were first progression-free survival (PFS1) and, in case of reintroduction of FOLFIRINOX, second progression free survival (PFS2). OS and PFS were estimated using the Kaplan-Meier method and compared using the log-rank test. Results: Among the 321 patients included, 147 (46%) received a maintenance therapy. Median age was 60.0 (53-66), 35 (24%) had locally advanced PC and 91 (62%) had metastatic PC. The median number of cycles of FOLFIRINOX was 9.0 (6.0-11.0). Median OS was 16.1 months (95%CI=13.7-20.3). Median PFS1 was 9.4 months (95%CI=8.5-10.4). The preferred maintenance regimen was FOLFIRI in 66 (45%), vs fluoropyrimidine (FP) in 52 (35%) and FOLFOX in 25 (17%). Among 118 Pts who received a maintenance CT with FP or FOLFIRI, there was no difference in PFS1 (median: 10.1 vs 9.0, respectively, p=0.33) or OS (median: 16.6 versus 18.7, p=0.86) between the 2 maintenance regimens. After progression under maintenance CT with FOLFIRI or FP, reintroduction of FOLFIRINOX was performed in 20.2% of Pts, with a median PFS2 of 2.8 months (95%CI=2.0-22.3). The rates of G3-4 toxicity were significantly higher during FOLFIRI maintenance CT than with FP (41% vs 22%, p=0.03), especially neuropathy (73% vs 9%). Conclusions: FOLFIRINOX de-escalation in aPC is largely used in France. Fluoropyrimidine maintenance chemotherapy appears to be as effective as FOLFIRI.
