9542 Background: Anti-PD-1 antibody monotherapy (PD1) has been commonly used for patients with advanced acral melanoma (AM). However, recent studies have demonstrated the limited clinical efficacy of PD1 in AM compared to non-acral cutaneous melanoma, particularly in nail apparatus melanoma. Although advanced AM patients are strong candidates for first-line anti-PD-1 and anti-CTLA-4 combination therapy (PD1+CTLA4), data on the clinical efficacy of PD1+CTLA4 in AM are lacking. Thus, we aimed to compare the clinical efficacies of PD1+CTLA4 and PD1 in Japanese advanced AM patients. Methods: We retrospectively reviewed the clinical records of advanced AM patients treated with PD1+CTLA4 or PD1 as first-line immunotherapy at 23 Japanese institutions. Clinical response was assessed using the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Survival was estimated using Kaplan-Meier analysis. Toxicity was assessed according to CTCAE 4.0. Results: A total of 192 patients (median age, 72 years) with advanced AM (palm and sole melanoma, 135; nail apparatus melanoma, 57) were included in the study. PD1+CTLA4 and PD1 were used as first-line immunotherapy in 39 and 153 patients, respectively. The baseline demographics and characteristics were similar between the PD1+CTLA4 and PD1 groups, except for age (median age 67.3 vs. 73.2; P = 0.005). The objective response rate (ORR) in PD1+CTLA4 was significantly higher than that of the PD1 group (38.5% vs. 16.3%; P = 0.047). The median progression-free survival (PFS) and overall survival (OS) in the PD1+CTLA4 group tended to be longer than those of the PD1 group, but the differences were not significant (median PFS 7.3 months vs. 4.5 months; P = 0.19, median OS 43.6 months vs. 18.2 months; P = 0.19). In the subgroup analysis of the palm and sole melanoma cohorts, no significant differences in ORR, PFS, and OS were observed between the PD1+CTLA4 and PD1 groups (ORR 31% vs. 20.8%; P = 0.67, median PFS 5.3 months vs. 5.9 months; P = 0.87, median OS not reached vs. 22.3 months; P = 0.66). Meanwhile, the nail apparatus melanoma cohort in the PD1+CTLA4 group exhibited significantly higher ORR, and longer PFS and OS than the PD1 group (ORR 60% vs 6.1%; P < 0.001; median PFS 19.6 months vs 3.8 months; P = 0.008, median OS 43.6 months vs 13.5 months; P = 0.049). Due to immune-related adverse events in all cohorts, the treatment cessation rate was higher in the PD1+CTLA4 group than the PD1 group (59% vs. 11.8%). Conclusions: PD1+CTLA4 was clinically more efficacious than PD 1 in advanced AM patients. Notably, advanced nail apparatus melanoma patients were strong candidates for first-line PD1+CTLA4.

e16567 Background: ICI/TKI combinations are a new standard of care for the initial treatment (tx) of mRCC. Efficacy and toxicity of such combination regimens beyond the first-line (1L) setting remain unknown. Methods: We retrospectively reviewed charts for adult patients (pts) receiving an ICI/TKI combination in any line of tx for mRCC of any histology at one of two academic centers as of May 1, 2020. ICIs included pembrolizumab (Pm), nivolumab (Ni), ipilimumab (Ip), or avelumab (Av); TKIs included sunitinib (Su), axitinib (Ax), pazopanib (Pz), lenvatinib (Ln), or cabozantinib (Ca). Clinical data including pt demographics, histology, International mRCC Database Consortium (IMDC) risk group, tx history, and ICI/TKI tx and toxicity details were recorded. Outcomes included objective response rate (ORR), median progression-free survival (mPFS), and safety, analyzed via descriptive statistics and the Kaplan-Meier method. Results: Of 85 pts, 69 (81%) were male and 67 (79%) had clear cell histology. IMDC risk was favorable (24%), intermediate (54%), poor (20%), and unknown (2%). 39% had ICI/TKI tx in the 1L setting. ICI/TKI regimens included Pm/Ax (33%), Ni/Ca (25%), Ni/Ax (20%), Av/Ax (11%), Ni/Ip/Ca (8%), Ni/Su (2%), and Ni/Ln (1%). ORR and mPFS stratified by line of tx and prior tx are shown in the table. Of 52 pts who received ICI/TKI tx as salvage (after 1L), 52% had a grade 3 or higher (≥G3) adverse event (AE), of which the most common were anorexia (13.5%), diarrhea and hypertension (11.5% each), and fatigue (9.6%). 65% of pts on salvage ICI/TKI tx stopped tx for progression/death, while 16% stopped tx for ≥G3 AE. ≥G3 AE rates by line of tx were 62.5% (2L), 50% (3L), and 45% (≥4L). Conclusions: ICI/TKI combination therapy is effective and safe beyond the 1L setting. Prior tx history appears to impact efficacy but has less of an effect on safety/tolerability. These observations will need to be confirmed in prospective studies.[Table: see text]

Background. We investigated the efficacy of TILs and anti-PD1 combination therapy in patients with metastatic cervical cancer with low MSI expression and PDL1-negative. Methods. A total of 80 patients were put on TILs and anti-PD1 combination therapy, and the progression-free survival time (PFS) and overall survival time (OS) were assessed by Kaplan–Meier analysis. Univariate and multivariate analyses were performed to identify factors that could predict the prognosis of metastatic cervical cancer in the previously described patients. Results. The objective response rate was 25%, whereas the mPFS and mOS were 6.1 and 11.3 months, respectively. The therapeutic efficacy was influenced by the characteristics of TILs, infection with HPV, and development of fever just after the therapy. Conclusion. Overall, our results show that the combination therapy of TILs and anti-PD1 significantly improves the prognosis of metastatic cervical cancer.

Abstract Background Several antiangiogenic tyrosine kinase inhibitors (TKIs) have the potential to modulate the tumor immune microenvironment and improve immunotherapy effect Of these, anlotinib has demonstrated antitumor efficacy in clinical trials. However, its role in immune regulation and the potential synergistic antitumor effect of its combination with PD-1 inhibitor remain unclear. This study investigated the efficacy and adverse events (AEs) of the combination of anlotinib and PD-1 inhibitor for solid tumors in real-world settings. Methods This retrospective study included patients with metastatic solid tumors treated with anlotinib plus PD-1 inhibitor at Huashan hospital, Fudan University between October 1, 2018 and August 31, 2020. The objective response rate was assessed using the response evaluation criteria in solid tumors v1.1. Descriptive statistics were performed using the Kaplan–Meier method, and any AEs were noted. Results Partial response was achieved in 13 patients, and 8 patients showed stable disease, representing a response rate of 43.3% and a disease control rate of 70%. The median progression-free survival was 3.8 months. Although AEs were observed in 50% of patients, most of them were Grades 1–2 and well tolerated. The most common AEs were thrombocytopenia (16%), thromboembolic or hemorrhagic events (16%), and rash (13%). Conclusions Anlotinib plus PD-1 inhibitor is an alternative salvage treatment choice in metastatic solid tumors with Favorable efficacy and tolerable toxicities.

e21507 Background: Clinical data on PD-1 inhibitor combined with interferon in metastatic melanoma treatment were still limited. The objective of this study was to assess the efficacy and safety of PD-1 inhibitor/interferon-α1b combination therapy for Chinese metastatic melanoma patients in the real world. Methods: We reviewed patients diagnosed as metastatic melanoma and had received PD-1 inhibitor (pembrolizumab, 2 mg/kg, every 3 weeks, intravenously or toripalimab 240mg every 2 weeks, intravenously) combined with interferon-α1b(10μg/kg, every other day, subcutaneously) in Xijing Hospital from Dec 2018 to Nov 2020. Efficacy and safety profiles were evaluated using Response Evaluation Criteria in Solid Tumors version 1.1 and Common Terminology Criteria for Adverse Events version 5.0, respectively. Results: In total 65 patients were reviewed in this study, including 13 cases with ECOG performance status ≥2. Acral and mucosal cases accounted for 47.7% and 23.1% respectively. In 27(41.5%) patients, the combination therapy was used as the first line treatment, whereas in the rest 38 patients as second or subsequent lines. The median follow-up period was 8 months (1.5-21 months). Median OS was 15 months (95CI%: 10.62-19.38 months). Median PFS was 6 months (95CI%: 2.54-9.46 months). 6-month and 1-year PFS rate were 48.1% and 35.3%. 6-month and 1-year OS rate were 80.9% and 59.8%. Objective response was seen in 18.46% cases, with 12.31% of patients exhibiting ongoing response. The best confirmed disease control rate was 73.85%. Multivariate analysis demonstrated that overall survival was significantly associated with ECOG performance status ≥2 (OR=3.32，95%CI=1.14-9.66 ), regardless of age(≥65), elevated LDH, PD-1 inhibitor type and the line of the combination therapy. Select treatment related AEs (TRAEs) of any grade were observed in 57(87.69%) patients. The leading 3 TRAEs were lymphopenia, fatigue and fever. Grade 3 to 4 TRAEs were recorded in 2 cases. Grade 4 hyponeutrophilia occurred in a patient with ECOG status 3 using interferon-α1b plus toripalimab and resulted in discontinuation of both PD-1 inhibitor and IFN-α1b. Grade 3 headache was reported by one patient using interferon-α1b plus pembrolizumab and was solved with celecoxib 200mg daily. No drug-related deaths were reported. Conclusions: PD-1 inhibitor combining interferon-α1b therapy shows promising efficacy and acceptable toxicity in this real-world cohort of Chinese metastatic melanoma patients.[Table: see text]

512 Background: Angiogenesis is an important therapeutic target in CRC; VEGF plays a key role in angiogenesis. RAM is a human IgG1 monoclonal antibody that targets the extracellular domain of VEGFR-2. The RAISE study evaluated the efficacy and safety of adding RAM to standard second-line treatment FOLFIRI. Methods: Eligible pts with mCRC who progressed on or after first-line combination therapy with bev, ox, and fp, had an ECOG PS of 0 or 1, and adequate organ function were randomized 1:1 (stratified by region, KRAS mutation status, and time to progressive disease [PD] after beginning first-line treatment) to receive RAM (8 mg/kg IV) plus FOLFIRI or PBO plus FOLFIRI every 2 weeks until PD, unacceptable toxicity, or death. The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and safety. Planned sample size of 1,050 pts ensured 85% power to demonstrate statistical significance at an overall two-sided alpha of 0.05, assuming a hazard ratio (HR) of 0.8. Results: Between Dec 2010 and Aug 2013, 1,072 eligible pts were randomized (RAM 536; PBO 536). Baseline pt characteristics were similar between treatment arms. The OS HR was 0.84 (95% CI: 0.73, 0.98; log-rank p=0.0219). Median OS was 13.3months (m) for RAM vs 11.7m for PBO. The PFS HR was 0.79 (95% CI: 0.70, 0.90; log-rank p = 0.0005). Median PFS with RAM was 5.7m and 4.5m for PBO. ORR was 13.4% RAM; 12.5% PBO (p = 0.6336). Subgroup results were consistent with the OS and PFS results. Grade ≥3 adverse events (AEs) occurring in >5% of pts in RAM+FOLFIRI were: neutropenia (RAM 38.4% vs PBO 23.3% ), hypertension (11.2% vs 2.8%), diarrhea (10.8% vs 9.7%), and fatigue (11.5% vs 7.8%). Conclusions: RAISE met its primary end-point, demonstrating a statistically significant improvement in OS for RAM and FOLFIRI vs PBO and FOLFIRI in second-line mCRC pts. Benefits were similar across important clinical subgroups and no unexpected AEs were identified. Clinical trial information: NCT01183780.

e20527 Background:Platinum-based chemotherapy is the standard first-line treatment for non-squamous NSCLC patients without driver oncogene (EGFR, KRAS, and ALK mutations). However, it remains unknown that from which chemotherapy regimens can those patients get more benefit. Therefore, the study explore whether pemetrexed combined with platinum chemotherapy is superior to the other platinum-based chemotherapy regimens.Methods:We performed a retrospective study on 114 histologically or cytologically advanced IIIB-IV NSCLC patients admitted to Cancer Hospital from 1 Jan 2013 to 30 Dec 2015. The primary endpoint was the median progression free survival (PFS) and the disease control rate (DCR). And objective response was evaluated every two cycles by imaging according to the Response Evaluation Criteria In Solid Tumors (RECIST version 1.0). The multivariate logistic analyses were carried out by SPSS version 16.0. Results:114 patients received platinum-base doublet as first-line treatment. Among them, 59 patients underwent pemetrexed-containing regimens, and 55 patients received non-pemetrexed-containing regimens (38 patients for paclitaxel-containing regimens, 13 patients for gemcitabine-containing regimens, and 4 patients for other regimens.). The baseline characteristics between two groups were comparable ( p>0.05). The median PFS of pemetrexed-containing regimens was significantly longer compared with that of non-pemetrexed-containing regimens (7.2 months [95% CI: 5.3–9.1] vs. 4.9 months [95% CI: 3.2–6.6], p%0.05). DCR of pemetrexed-containing regimens was better than that of non-pemetrexed-containing regimens in the multivariate logistic analysis (89.8% vs.74.5%, p%0.05).Conclusions:Pemetrexed-containing regimens displayed more benefit than the other chemotherapy regimens for non-squamous NSCLC patients without driver oncogene. However, large scale perspective study is warranted in the future.

4524 Background: Patients with advanced gastric or gastro-oesophageal junction cancer that progresses on chemotherapy have poor outcomes. We investigated HX008, an Anti-PD1 Antibody, with irinotecan in patients with advanced gastric or gastro-oesophageal junction cancer that progressed on first-line chemotherapy with a platinum and/or fluoropyrimidine. Methods: This study is a multicenter, open, phase II clinical study of recombinant humanized anti-pd-1 monoclonal antibody HX008 injection plus Irinotecan that was conducted at 11 hospitals in China. Eligible patients are adults with histologically confirmed advanced gastric or gastro-oesophageal junction cancer. Subjects participating in this study are required to submit a archived tumor tissue specimen or newly obtained biopsy of tumor lesions at the site of no previous radiotherapy and peripheral blood (2mL) for detection of PD-L1 and MSI/MMR expression. The samples will be tested for expression of PD-L1 and MMR by immunohistochemistry (IHC) in the central laboratory, and MSI levels will be determined by polymerase chain reaction (PCR) and gel electrophoresis. Subjects received PD-1 monoclonal antibody HX008 at 200mg (d1, intravenous drip, once every 3 weeks) plus irinotecan at 160mg/m2 (d1, intravenous drip, 60 ~ 120min, once every 2 weeks). Response was assessed every 6 weeks in accordance with Response Evaluation Criteria in Solid Tumors version 1.1. Primary endpoints was objective remission rate (ORR). Results: Between October 2018 and September 2019, a total of 58 patients with advanced gastric or gastro-oesophageal junction cancer were enrolled in this study. Median (range) age was 61 (27-71) years, and most patients were male (72.4%). Among 53 patients who were evaluated, 15 (28.3%) experienced objective response and 22 (41.5%) experienced stable disease (SD). The median progression free survival (PFS) was 5.4 months, the one-year survival rate was 71.3%. The most common treatment-related adverse events of grade 3 or 4 included neutropenia(31.0%), anemia(15.5%), loss of appetite (6.9%), vomiting(5.2%), nausea(3.4%), diarrhea (1.7%) and fatigue (1.7%). There were no treatment-related deaths. Conclusions: HX008 injection plus Irinotecan demonstrated promising activity and manageable safety in patients with advanced gastric or gastro-oesophageal junction cancer that progressed on first-line chemotherapy with a platinum and fluoropyrimidine. Clinical trial information: NCT03704246 .

Summary Background Esophageal cancer is a very common malignant tumor in China, especially esophageal squamous cell carcinoma (ESCC), but there is currently no effective treatment for patients after first-line chemotherapy failure. Apatinib has shown promising outcomes in treatment with various solid tumors. Objectives To evaluate the clinical efficacy and safety of apatinib combined with S-1 in the treatment of advanced ESCC patients after first-line chemotherapy failure. Methods In this prospective study, fifteen patients with advanced ESCC who failed first-line chemotherapy were enrolled from Nov 2016 to Apr 2019. Patients received the combination therapy with apatinib (250-500 mg, once daily) plus S-1 (40–60 mg based on body surface area, twice daily). Primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), disease control rate (DCR) and objective response rate (ORR). Adverse events (AEs) were recorded to evaluate the safety. Results A total of 12 patients were included in the efficacy analysis. The median PFS was 6.23 months, and the median OS was 8.83 months. Two (16.67%) patients achieved partial remission, 9 patients (75.00%) achieved stable disease and 1 (8.33%) patient achieved progressive disease. DCR and ORR was 91.67%and 16.67%, respectively. Most frequent AEs were hypertension, myelosuppression, weakness, hemorrhage, hand-foot syndrome, total bilirubin elevation, sick, proteinuria, oral ulcer, loss of appetite, and transaminase elevation. The most AEs were in grade I~II. Conclusion The combination therapy of apatinib plus S-1 was effective and well tolerated in the treatment of advanced ESCC patients after first-line chemotherapy failure. The combination therapy has the potential to be a potent therapeutic option for advanced ESCC patients after first-line chemotherapy failure.

9529 Background: Anti-PD-1 antibodies are used worldwide for patients (pts) with advanced melanoma. Clinical trials have demonstrated its efficacy and safety for nonacral cutaneous melanoma (NACM) in controlled settings. Since acral melanoma (AM) is epidemiologically and molecularly distinct from NACM, data on the real-world efficacy of anti-PD1 antibodies in advanced AM is still lacking. Thus, we aim to analyze the real-world efficacy and safety of anti-PD-1 antibodies in advanced AM. Methods: We retrospectively reviewed clinical records of advanced AM treated in any line with an anti-PD1 antibody at 21 Japanese institutions. Clinical response was assessed by (Response Evaluation Criteria in Solid Tumors) RECIST criteria. Survival was estimated using Kaplan-Meier analysis. Toxicity was assessed according to CTCAE 4.0. Results: A total of 193 pts (median age, 71 years) with advanced AM (subungual, 70; palm and sole, 123) were included in the study. Anti-PD-1 antibody was used as first-line therapy in 143 pts (74.1%). Nivolumab was used in 168 pts and pembrolizumab in 25 pts. Base-line lactate dehydrogenase (LDH) was within normal level in 102 pts (52.8%). The objective response rate (ORR) of all pts was 16.5% (complete response 3.1%, partial response 13.5%), and median overall survival (OS) was 18.1 months. Normal LDH level was significantly associated with better prognosis than abnormal level (median OS 24.9 vs 10.7 months; P < 0.001). Although baseline demographics and characteristics were almost similar between subungual group and palm and sole group, ORR was significantly lower in the subungual group than in palm and sole group (6/70 pts [8.6%] vs 26/123 pts [21.1%]; P = 0.026); median OS was significantly poorer as well (12.8 vs 22.3 months; P = 0.031). Immune-related adverse events of grades 3 to 5 occurred in 27 pts (14.0%). One patient (0.5%) died of grade 5 myasthenia gravis. Conclusions: Real-world efficacy of anti-PD-1 antibodies in AM pts is limited. Notably, pts with subungual melanoma showed poorer response and survival, making them strong candidates for further research of efficacy of anti-CTLA-4 and anti-PD-1 combination therapy.
