Abstract BackgroundMucosal melanoma is rare and has distinct clinical and genetic features. Even with advances in targeted and immune therapy, the survival of patients with advanced or recurrent mucosal melanomas remains poor. The standard treatment remains controversial and we conducted this real-world study aimed to test continuous intravenous Endostar infusion plus chemotherapy in this population in the first-line setting. Methods Overall, 43 patients with advanced or recurrent mucosal melanoma treated at Fudan University Shanghai Cancer Center between April 2017 and August 2020 were retrospectively included. Patients received dacarbazine plus cisplatin or temozolomide plus cisplatin regimens per the investigators’ preference. Endostar (105 mg/m2) was administered with continuous infusion for 168 hours (Civ 168h). ResultsOf the 43 patients, 72.1% had metastatic disease, and the most common primary site was the gastrointestinal tract (51.2%). The most commonly observed mutations were NRAS (23.1%), BRAF (7.7%) and CKIT (5.1%). An objective response was observed in 12 (30.0%) of the 40 evaluable patients, and disease control was achieved in 31 (77.5%) patients. With a median follow-up of 17.6 months, the median progression-free survival (PFS) and overall survival (OS) were 4.9 and 15.3 months, respectively. Additionally, a high lymphocyte-to-monocyte ratio (LMR) (p=0.023, HR 0.29, 95% CI: 0.10-0.84) and BRAF/KIT/RAS mutation (p=0.028, HR 0.24, 95% CI: 0.07-0.86) were independently correlated with prolonged OS. Toxicity was manageable overall. ConclusionContinuous Endostar infusion plus chemotherapy was effective and safe for the treatment of advanced or recurrent mucosal melanoma. A high LMR was correlated with favorable PFS and OS in this patient population.

e21517 Background: Mucosal melanoma is rare and has distinct clinical and genetic features. Even with advances in targeted and immune therapy, the survival of patients with advanced or recurrent mucosal melanomas remains poor. The standard treatment remains controversial and we conducted this real-world study aimed to test continuous intravenous Endostar infusion plus chemotherapy in patients with advanced or recurrent mucosal melanoma in the first-line setting. Methods: In total, all 43 patients with advanced or recurrent mucosal melanoma treated at Fudan University Shanghai Cancer Center between April 2017 and August 2020 were retrospectively included. Patients received dacarbazine plus cisplatin or temozolomide plus cisplatin regimens per the investigators’ preference. Endostar (105 mg/m2) was administered with continuous infusion for 168 hours (Civ 168h). Results: Of the 43 patients, 72.1% had metastatic disease, and 27.9% had locally advanced disease. The most common primary site was the gastrointestinal tract (51.2%), followed by the sinonasal tract (32.6%) and genitourinary tract (14.0%). The most commonly observed mutation was NRAS (23.1%), followed by BRAF (7.7%) and CKIT (5.1%). An objective response was observed in 12 (30.0%) of the 40 evaluable patients, and disease control was achieved in 31 (77.5%) patients. With a median follow-up of 17.6 months, the median progression-free survival (PFS) and overall survival (OS) were 4.9 and 15.3 months, respectively. Multivariate analysis indicated a high lymphocyte-to-monocyte ratio (LMR) was significantly correlated with favorable PFS (p = 0.012, hazard ratio [HR] 0.28, 95% CI: 0.10-0.76). Additionally, a high LMR (p = 0.023, HR 0.29, 95% CI: 0.10-0.84) and BRAF/KIT/RAS mutation (p = 0.028, HR 0.24, 95% CI: 0.07-0.86) were independently correlated with prolonged OS. Toxicity was manageable overall. Conclusions: Continuous Endostar infusion in combination with chemotherapy was effective and safe for the treatment of advanced or recurrent mucosal melanoma. Additionally, a high LMR was correlated with favorable PFS and OS in this patient population.

269 Background: MCC is a rare, aggressive disease associated with poor prognosis. Avelumab, a fully human anti–PD-L1 monoclonal antibody, was the first immune checkpoint inhibitor approved by the FDA for the treatment of metastatic MCC (mMCC). In the JAVELIN Merkel 200 trial (Clinical trial information: NCT02155647), avelumab resulted in durable responses and a high objective response rate (ORR) in pts with mMCC. This retrospective descriptive study assessed real-world clinical outcomes in avelumab-treated pts with locally advanced MCC (laMCC) and mMCC in a US community oncology setting. Methods: This study included data on avelumab-treated laMCC and mMCC pts from 1/1/17 to 3/31/19 within The US Oncology Network. Study data were captured through 9/30/19 using structured fields and chart review of iKnowMed electronic healthcare records. Real-world ORR was assessed. Duration of response (DOR), progression-free survival (PFS), and overall survival (OS) were estimated using the Kaplan-Meier method. Results: 33 pts initiated treatment with avelumab (laMCC n = 11; mMCC n = 22) and were followed up for a median of 10.9 months (range, 0.5-27.2 months). Median age was 77 years (range, 44-90+ years), 78.8% of pts were male, and the majority (84.8%) of pts were treated in the first-line setting. During treatment, 27.2% of pts had emergency department visits and 39.4% were hospitalized; 1% and 23.1%, respectively, were treatment related. Clinical outcomes are reported in the table. Conclusions: This is the first study to examine pts with laMCC treated with avelumab in a real-world setting. Although the sample population is small, results suggest the clinical benefits in the real world in pts with mMCC treated with avelumab are consistent with benefits reported in the JAVELIN Merkel 200 trial.

<b><i>Background:</i></b> Lenvatinib has been recently approved as a first-line treatment option for patients with unresectable hepatocellular carcinoma (HCC) in Korea. We aimed to study the efficacy and safety of lenvatinib therapy in a real-world practice and to find prognostic factors related to survival and disease progression. <b><i>Methods:</i></b> A hospital-based retrospective study was conducted on 111 consecutive patients who had unresectable HCC and were treated with lenvatinib at Samsung Medical Center from October 2018 to March 2020. Efficacy was determined using the modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria in 111 patients who completed 1st tumor assessment. Safety was evaluated in 116 HCC patients including 5 patients who discontinued lenvatinib due to adverse events (AEs) before 1st tumor assessment using Common Terminology Criteria for AEs version 5.0. <b><i>Results:</i></b> A total of 111 patients with a median age of 59 years were analyzed during a median follow-up duration of 6.2 (4.4–9.0) months. The Kaplan-Meier estimate of overall survival was 10.5 months, and the median progression-free survival was 6.2 months. Based on mRECIST criteria, the objective response rate was 18.9% and disease control rate was 75.7%. AEs developed in 86/116 (74.1%) patients, and grade ≥3 AEs developed in 16/116 (13.8%) patients. Diarrhea, hand-foot skin rash, abdominal pain, hypertension, and anorexia were identified as the AEs with the highest frequencies of any grade. REFLECT eligibility criteria including tumor extent ≥50% liver occupation or inadequate bone marrow function and occurrence of anorexia were prognostic factors for survival, and occurrence of diarrhea was a favorable factor for disease progression. <b><i>Conclusion:</i></b> Lenvatinib therapy showed a favorable efficacy and safety in a real-world practice. The REFLECT eligibility criteria and specific AEs could be one of the prognostic markers.

Introduction: Rearranged during transfection (RET) gene fusions are rare genetic drivers in non-small cell lung cancer (NSCLC). Selective RET-inhibitors such as selpercatinib have shown therapeutic activity in early clinical trials; however, their efficacy in the real-world setting is unknown. Methods: A retrospective efficacy and safety analysis was performed on data from RET fusion-positive NSCLC patients who participated in a selpercatinib access program (named patient protocol) between August 2019 and January 2021. Results: Data from 50 patients with RET fusion-positive advanced NSCLC treated with selpercatinib at 27 centers in 12 countries was analyzed. Most patients were Non-Asian (90%), female (60%), never-smokers (74%), with a median age of 65 years (range, 38–89). 32% of the patients had known brain metastasis at the time of selpercatinib treatment. Overall, 13 patients were treatment-naïve, while 37 were pretreated with a median of three lines of therapy (range, 1–8). The objective response rate (ORR) was 68% [95% confidence interval (CI), 53–81] in the overall population. The disease control rate was 92%. The median progression-free survival was 15.6 months (95% CI, 8.8–22.4) after a median follow-up of 9 months. In patients with measurable brain metastases ( n = 8) intracranial ORR reached 100%. In total, 88% of patients experienced treatment-related adverse events (TRAEs), a large majority of them being grade 1 or 2. The most common grade ⩾ 3 TRAEs were increased liver enzyme levels (in 10% of patients), prolonged QTc time (4%), abdominal pain (4%), hypertension (4%), and fatigue/asthenia (4%). None of patients discontinued selpercatinib treatment for safety reasons. No new safety concerns were observed, nor where there any treatment-related death. Conclusions: In this real-world setting, the selective RET-inhibitor selpercatinib demonstrated durable systemic and intracranial antitumor activity in RET fusion-positive NSCLC and was well tolerated.

Background: Myxofibrosarcoma is a type of soft-tissue sarcoma that is associated with high rates of local recurrence and distant metastases. The first-line treatment for metastatic soft-tissue sarcoma has conventionally been doxorubicin-based. Recent evidence suggests that myxofibrosarcoma may be molecularly similar to undifferentiated pleomorphic sarcoma (UPS), which is particularly sensitive to gemcitabine-based therapy. The goal of this study was to evaluate the activity of gemcitabine-containing regimens for the treatment of metastatic myxofibrosarcoma refractory to doxorubicin. Material and Methods: We retrospectively evaluated seven consecutive cases of metastatic myxofibrosarcoma at our institution treated with gemcitabine-based therapy in the second-line setting, after progression on doxorubicin. Baseline clinical and baseline characteristics were collected. Primary endpoints were objective response rate (ORR), progression-free survival (PFS) and overall survival (OS). Results: After progression on first-line doxorubicin, a partial, or complete radiological response was observed in four of seven patients who received gemcitabine-based chemotherapy. With a median follow-up of 14 months, median progression-free and overall survival were 8.5 months and 11.4 months, respectively. Conclusions: Gemcitabine-based chemotherapy was associated with encouraging response rates in this cohort, similar to those seen in UPS. Both entities could be studied together for novel gemcitabine-based regimens.

9511 Background: Mucosal melanoma is a rare malignant melanoma in Caucasians but ranks the second most common subtype in the Asian population. It is more often diagnosed at an advanced stage and responds poorly to current PD-1/PD-L1 inhibitors. Here we report the interim analysis results of ML41186, an open-label, multicenter, single-arm phase II study, aiming to evaluate the efficacy and safety of atezolizumab in combination with bevacizumab in patients (pts) with advanced mucosal melanoma. Methods: Eligible pts aged 18 to 75 years with histologically confirmed unresectable locally advanced or metastatic mucosal melanoma had at least one measurable lesion per RECIST version 1.1 at baseline, with an ECOG PS 0 or 1 and adequate hematologic and organ function. ML41186 is a Simon two-stage design study, if 22 pts completed ORR evaluation and more than 3 pts respond in stage I, the study then continue to Stage II. Atezolizumab and bevacizumab were administered at a fixed dose of 1200 mg and 7.5 mg/kg Q3W respectively (on day 1 of each 21-day cycle) until unacceptable toxicity or loss of clinical benefit. The primary endpoint is the objective response rate (ORR). The secondary endpoints include progression-free survival (PFS), duration of objective response (DoR), disease control rate (DCR), and safety. Results: By the cut-off date of 9th September 2020, 35 pts has been enrolled, among whom 22 pts in the stage I analysis set has completed two efficacy evaluation, while 28 pts (full analysis set) has completed at least one efficacy evaluation. In ITT populations (n=35), mean age was 58.9 years with 10 (28%) pts had ECOG PS of 1. LDH level elevated in 9 (25.7%) pts. More than half pts (19, 54.3%) had metastatic mucosal melanoma, of whom 3 (15.8%) pts had more than 3 metastasis sites and 4 (21.1%) pts had liver metastasis. In stage I analysis set (n=22), the best confirmed ORR was 36.4% (95% CI, 17.0%-59.3%). Median progression-free survival was 5.32 months (95% CI, 1.58-not reached), and the best confirmed DCR was 59.1% (95%CI, 36.4%-79.3%). The median confirmed DoR was not reached (95% CI, 2.76-NR). In the full analysis set (n=28), the unconfirmed ORR was 42.9% (95%CI, 24.5%-62.8%). In ITT populations (n=35), 28 pts (80%) experienced at least one adverse event (AE) and 5 pts (14.3%) experienced at least one grade 3-4 AEs. Only one patient experienced AE leading to treatment discontinuation. One patient died of autoimmune lung disease. Conclusions: The combination of atezolizumab plus bevacizumab showed promising benefit and was tolerable in pts with advanced mucosal melanoma. At the time of this interim analysis, the primary endpoint did not cross the futility boundary, thus the study will run into Stage II. Clinical trial information: NCT04091217.

Abstract Background The identification of biomarkers to select patients with metastatic renal cell carcinoma (mRCC) most likely to respond to combination immunotherapy (IO) is needed. We sought to investigate an association of the baseline neutrophil-to-eosinophil ratio (NER) with outcomes to nivolumab plus ipilimumab for patients with mRCC. Methods We performed a retrospective review of patients with clear cell mRCC treated with nivolumab plus ipilimumab from Vanderbilt-Ingram Cancer Center and Duke Cancer Institute. Patients with prior receipt of immunotherapy and those without available baseline complete blood count with differential were excluded. Patients were divided into groups by the median baseline NER and analyzed for overall survival (OS), progression free survival (PFS), and objective response rate (ORR). Patients were also divided by median baseline neutrophil-to-lymphocyte ratio (NLR) and analyzed for clinical outcome. Further analyses of patients above/below the median NER and NLR were performed in subgroups of IMDC intermediate/poor risk, IMDC favorable risk, and treatment naïve patients. Results A total of 110 patients were included: median age was 61 years and 75% were treatment naïve. The median NER (mNER) at baseline was 26.4. The ORR was 40% for patients with <mNER compared to 21.8% among patients with >mNER (OR 2.39, p = 0.04). The median PFS for patients with <mNER was significantly longer at 8.6 months (mo) compared to 3.2 mo for patients with >mNER (HR 0.50, p < 0.01). Median OS was not reached (NR) for patients with <mNER compared with 27.3 mo for patients with >mNER (HR 0.31, p < 0.01). The median NLR (mNLR) was 3.42. While patients with <mNLR showed improvement in OS (HR 0.42, p = 0.02), PFS and ORR did not differ compared with patients in the >mNLR group. Conclusions A lower baseline NER was associated with improved clinical outcomes (PFS, OS, and ORR) in patients with mRCC treated with nivolumab plus ipilimumab, and prospective validation of the baseline NER as a predictive biomarker for response to immunotherapy-based combinations in mRCC is warranted.

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.

e16098 Background: Systemic therapy options for patients with advanced gastric cancer (GC) are limited. We here presented the efficacy results for advanced GC patients matched to targeted therapies or immunotherapies based on the identification of tumor tissue genotypes. Methods: We selected 30 patients diagnosed between 2014 and 2020 with advanced GC at Nanjing Drum Tower Hospital, the affiliated Hospital of Nanjing University Medical School identified with actionable alterations and received ≥1 matched therapies. Tumor biopsy specimens from the patients were analyzed using NGS and/or selected immunohistochemistry and fluorescence in situ hybridization. Results: In these 30 patients, median age at diagnosis was 63 years (range 28-83) and 6 (20%) were female. In total, 11 (37%) harbored c-MET amplification/overexpression (received savolitinib or crizotinib, cohort A), 9 (30%) harbored HER2 mutation/overexpression (received RC48-ADC or trastuzumab, cohort B), 6 (20%) dMMR/MSI-H/TMB-H (received sintilimab, pembrolizumab, tislelizumab or nivolumab, combined with antivascular or not, cohort C), 2 (7%) KIT mutation/amplification (received imatinib or anlotinib, cohort D), 1 (3%) BRAF V600E mutation (received vemurafenib, cohort E) and 1 (3%) EGFR mutation (received afatinib, cohort F). Except for three patients in cohort C, all patients received at least one previous line systemic therapy. In cohort A, three of 11 patients had an objective response (1 complete response and 2 partial responses, objective response rate (ORR) 27%), disease control rate (DCR) was 45%, median progression-free survival (mPFS) was 2.1 months, and median overall survival (mOS) was 3.7 months. In cohort B, ORR was 44% (4/9), DCR was 78% (7/9), mPFS and mOS was 3.1 months and 5.5 months, respectively. In cohort C, ORR was 17% (1/6), DCR was 67% (4/6), mPFS and mOS was 1.9 months and 6.8 months, respectively. In cohort D, no patient had objective response or disease control. In cohort E, the one patient had PR. Stable disease was observed in the patient in cohort F. In all cohorts, ORR was 30% (9/30), DCR was 60% (18/30), mPFS and mOS was 2.7 months and 5.8 months, respectively. Conclusions: Overall, 30 patients with advanced GC were treated with matched therapies according to specific genotype. These real-world outcomes suggested that matched therapies for advanced GC has promising efficacy, supporting the adoption of genotyping in treatment determination.

281 Background: TACE and lenvatinib has each shown to prolong overall survival in patients with unresectable HCC, combination of which may also improve clinical outcomes and have been widely used in the real world accordingly. However, the optimal timing of adding on lenvatinb to TACE remains unclear. We are aiming to evaluate the efficacy and safety between two combination strategies. Methods: From Nov 2018 to Jun 2020, 79 consecutive patients had received a combination treatment of lenvatinib and TACE. Patients followed up for more than 2 months were included in this analysis. They were classified as early-combination group(add on lenvatinib before or after the first TACE ) and late-combination group(add on lenvatinib after at least two procedures of TACE ). Tumor response and progression-free survival (PFS,time from the first day of prescribing lenvatinib to progression or death) were assessed according to RECIST1.1 criteria. Liver function were also evaluated at baseline and every 2 months later. AEs were recorded during the combination treatment period according to CTCAE 5.0. Results: A total of 48 u-HCC patients was finally enrolled. Median follow-up in all patients was 9.3(5.3-14.3)months. Patients’ baseline characteristics were similar in two groups. For early-combination group(n=22)and late-combination group(n=26), the mean age was 65±9.7 and 61±11.6years(p=0.2);BCLC stage C HCC was 59% and 54%(p=0.89);and Child-Pugh A proportion was 81.8% and 77%(p=0.73) respectively. The objective response rate(ORR) was 22.9% in total 48 cases. There was no significant difference in response rate (18.2% vs 26.9%, P=0.51) or disease control rate (90.9% vs 92.3%, P=1.00). Median PFS was significantly longer in the early-combination group than that in late-combination group (14.5 vs 8.9 months; p=0.048). The safety profile was similar between two groups. Grade 3/4 adverse events were 3 (13.6%) and 2 cases(7.7%) respectively (P=0.65). Conclusions: This is to date the first real-world data of the combination timing of lenvatinib with TACE in u-HCC patients. Early-combination strategy may be a better option for the u-HCC patients with a longer mPFS.
