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.

Objective: To explore the clinical efficacy and safety of camrelizumab in the treatment of digestive system malignancies in the real world. Methods: A retrospective study was designed. A total of 34 patients with advanced gastrointestinal cancer who received camrelizumab treatment in the xx hospital from July 2019 to May 2020 were included. The follow-up endpoint was set for October 30, 2020. The primary endpoint was objective response rate (ORR) and safety. Secondary endpoint measures included progression-free survival (PFS), and overall survival (OS). Cox regression was used for the analysis of factors associated with PFS. Results: As the best response, only 5 patients achieved a partial response and 10 patients had disease progression, with an ORR of 14.31%. Compared with gastric cancer, the ORR of esophageal cancer (3.0% vs 0.0%) (P<0.05). The PFS was 4.5 months (2-10 months). OS ranged from 4 to 11 months, and median OS has not been reached. Multivariate Cox regression analysis showed that gastric cancer (HR=1.695, 95% CI:11.216–2.435, P<0.05) was associated with still shorter PFS, and camrelizumab combined with other drugs (HR=0.512, 95% CI: 0.095–0.737, P<0.01) was associated with PFS in patients. The most common AEs were anemia (41.2%, 14/34) in all grades 1 to 2. Grade 3 AEs occurred in 3 patients (2.9%), including 1 case of immune pneumonitis, 1 case of hemangioma, and 1 case of transaminase increased. Other adverse events included diarrhea, nausea, neutropenia, thrombocytopenia, reactive cutaneous capillary proliferation (RCCEP), fatigue, and hypothyroidism, all of which did not exceed 12%. Conclusion: Camrelizumab is effective and safe in the treatment of patients with digestive system malignancies, but the overall response rate is limited.

108 Background: GT0918 is a 2nd generation of AR antagonist and capability to down-regulate AR level. This study is an open-label, randomized, multicenter, Ph II study to evaluate the safety and efficacy in patients with mCRPC, and to determine the optimal dose for Ph III study. Methods: Patients with historically confirmed mCRPC who progressed after/intolerant to/reluctant to receive Docetaxel and previously treated with abiraterone or enzalutamide were excluded. All the patients received up to 6 cycles or, unacceptable toxicity, or loss of clinical benefit as recommended by PCWG3. Primary endpoint was prostate-specific antigen (PSA) reduction from baseline. Secondary endpoints included time to PSA progression (TTPP), objective response rate (ORR), progression free survival (PFS), disease control rate (DCR) and safety profiles. Results: As of June 30, 2019, 108 treated with GT0918 at three dose levels: 100 mg (n =37), 200 mg (n = 35) and 300 mg (n = 36), the median age of patients was 70.0 years (range 63-77), 88% of patients had stage IV disease at the initial diagnosis and 69.4% had Gleason score ≥ 8. The median duration of disease was 2.88 years. All received prior endocrine therapy, 35.2% received prior chemotherapy, 29.6% received Docetaxel. The median PSA at baseline was 35.285ng/ml, PSA response rate (≥50 % reduction from baseline) was 41.9%. The median time to PSA progression was not reached. There was no significant difference among three arms. Of 19 evaluable patients with target lesions at baseline, the ORR was 15.8% (all were PR) assessed by IRC with RECIST v 1.1, with 20.0% (1/5), 22.2% (2/9), 0 (0/5) at 100, 200, 300 dose level, respectively. The DCR assessed by IRC was 78.9% (CR 0+PR15.8%+SD 63.2%). Of 26 evaluable patients with target lesions at baseline, the ORR was 19.2% assessed by investigators (CR 3.8%+PR 15.4%), with 11.1% (1/9), 20.0% (2/10), 28.6% (2/7) at 100, 200, 300 dose level, respectively. Overall, AEs were experienced by most of patients (94.4 %, n=102). AEs leading to drug interruption were reported in 13 patients (12.0%), 9 (8.3%)of them were suspected to be drug related. AEs leading to discontinuation were reported in 6 patients (5.6%), 3(2.8%) were possibly related to GT0918. 14 patients (13.0%) experienced Grade 3 and 4 AEs. 17 patients (15.7%)experienced SAE, 5(4.6%) of them were suspected to be related to study drug. Most of AEs were mild or moderate. The common suspected AE (≥10%) were asthenia (17.6%, n=19), anemia (14.8%, n=16), AST increased (14.8%, n=16), ALT increased (13.0%, n=14), decreased appetite (13.0%, N=14), white blood cell count decreased (12.0%, n=13), proteinuria (12.0%, n=13). Conclusions: GT0918 showed a manageable safety profile. This study provided preliminary anti-tumor activity in patients with mCRPC. 200mg/day is recommended dose for Ph III trial. Clinical trial information: CTR20170177.

Background: Liposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (5-FU/LV) was effective and well-tolerated in patients with metastatic pancreatic adenocarcinoma (mPAC) that progressed on gemcitabine-based therapy in the global NAPOLI-1 trial. Real-world data may further clarify the outcomes and safety profile of nal-IRI + 5-FU/LV in clinical practice. Methods: This retrospective analysis included patients with mPAC who received nal-IRI + 5-FU/LV following gemcitabine-based therapy under a Managed Access Program in Korea. Results: From January 2017 to April 2018, 86 patients across 10 institutions received nal-IRI + 5-FU/LV (median age, 61 years; 60% male; ECOG performance status, 0–1). A total of 35 (41%) and 51 (59%) patients had received less than two and two or more lines of chemotherapy before inclusion, respectively. At a median follow up of 6.4 months, median overall survival (OS) was 9.4 months (95% confidence interval [CI] 7.4–11.4) and median progression-free survival (PFS) was 3.5 months (95% CI 1.3–5.7). Six-month OS and PFS rates were 65.1% and 37.5%, respectively. Objective response and disease control rates were 10% and 55%, respectively. Most common grade 3–4 toxicities were neutropenia (37.2%), nausea (10.5%), vomiting (9.3%), anorexia (8.1%) and diarrhoea (4.7%). Conclusion: Real-life data for Korean patients indicate that, consistent with NAPOLI-1, nal-IRI + 5-FU/LV is effective and well-tolerated in patients with mPAC that progressed on gemcitabine-based therapy.

Background and Aims. Biomarkers for systemic inflammation have been introduced into clinical practice for risk-rating in cancer patients’ treatment. This study is aimed at confirming the prognostic role of the neutrophil-to-lymphocyte ratio (NLR) as an effective biomarker for patients with metastatic gastric cancer (MGC) receiving anti-PD-1 agents. Method. Patients with MGC who received anti-PD-1 treatment at the Chinese PLA General Hospital between January 2016 and November 2020 were reviewed. The study analyzed the association of NLR and overall survival (OS) or progression-free survival (PFS) and antitumor response rate with PD-1 inhibitors. Results. 137 patients were included in the final analysis. The area under the curve value of NLR for 6-month OS was 0.71. The best cut-off value for NLR was 3.23. NLR < 3.23 was associated with longer OS ( HR = 0.38 , 95% CI, 0.26-0.57, p < 0.001 ) and PFS ( HR = 0.42 , 95% CI, 0.29-0.62, p < 0.001 ) in patients with MGC. No significant difference was observed in the objective response rate (ORR) (35.8% vs. 28.6%, p = 0.377 ) and disease control rate (DCR) (86.4% vs. 78.6%, p = 0.229 ) in the NLR < 3.23 group and in the NLR ≥ 3.23 group, respectively. Univariate analysis and multivariate analysis found that NLR was an independent prognosis biomarker for PFS and OS. Conclusions. Pretreatment elevated NLR was significantly associated with inferior PFS and OS in patients with MGC who received anti-PD-1 inhibitors. Clinicians need to consider patients with elevated NLR for decisions on immunotherapy strategy.

137 Background: The aim of this study was to observe the safety of apatinib in the real world with wider inclusion criteria. The efficacy of apatinib was evaluated including overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and disease control rate (DCR). Methods: This trial enrolled patients from 32 centers in china with advanced gastric adenocarcinoma who had progressed after undergoing at least two lines of systemic chemotherapy, or patients who were considered to benefit from the treatment. We recommended starting from oral administration of 500mg qd, 28 days for a cycle. Dose could be appropriately adjusted according to the patients’ physical condition. Results: Between March 2015 and September 2017, 326 patients were enrolled. The average age was 62 years old, and the ratio of male to female was about 2:1. Patients received perioperative, first-line, second-line, and third-line or more treatment were 1,39,69 and 217 people respectively. There were 192 patients received efficacy evaluation, 9 patients achieved partial response(PR), 125 had disease stability(SD). The ORR and DCR were 4.6% and 69.8% respectively. The median PFS and median OS were 3.7 months and 7.3 months respectively. In the 326 patients, there were 153 patients with initial dose of 500 mg, 3 and 55 patients achieved PR and SD, respectively. The ORR and DCR were 3.3% and 63.7%, respectively. The median PFS and median OS were 3.5 months and 8.4 months, respectively. There were 237 patients in all 326 patients received safety analysis. Common adverse events were hypertension (57%), hand-foot skin reactions (26.6%), fatigue (29.5%), proteinuria (19.0%), bleeding (10.1%) and diarrhea (8.0%). The grade 3 to 4 adverse events were hypertension (6.3%), hand-foot skin reactions (3.8%), proteinuria(3.0%) and bleeding (2.1%). Conclusions: This real-world data in which more patients were given apatinib 500mg or less qd showed similar efficacy to Phase III clinical trial (850mg qd).The incidence of adverse events was consistent with that of Phase III clinical data,there was no new adverse events had been seen. Clinical trial information: NCT02668380.

e16138 Background: The combination of lenvatinib (LEN) and pembrolizumab (PEMBRO) showed promising response rates and survival in a phase 1b trial for patients with unresectable hepatocellular carcinoma (HCC). Whether LEN plus PEMBRO provides better outcomes than LEN monotherapy remains unclear. The aim of this study was to compare the outcomes of LEN plus PEMBRO versus lenvatinib monotherapy in patients with unresectable HCC in the real world setting. Methods: A total of 123 patients with unresectable HCC were retrospectively enrolled, including 61 patients with LEN monotherapy and 62 patients with LEN plus PEMBRO. We evaluated progression-free survival (PFS), overall survival (OS), objective response rate (ORR) and disease control rate (DCR) by RECIST 1.1 and modified RECIST (mRECIST) criteria. Results: One hundred and one (82.1%) patients were in BCLC stage C and 81 (65.9%) patients received LEN or LEN plus PEMBRO as first line setting. During a median follow-up period of 8.0 months, 71 (57.7%) and 31 (25.2%) of patients had disease progression and death, respectively. The median PFS was 8.4 and 4.9 months in the LEN plus PEMBRO and LEN monotherapy groups, respectively (p = 0.033). The median OS was not reached in the LEN-PEM group and was 17.2 months in the LEN monotherapy group (p = 0.064). Patients with LEN plus PEMBRO had higher objective response rate (ORR: 34.4% vs 23.7% by RECIST 1.1, p = 0.277; 57.4% vs 32.2% by mRECIST, p = 0.010) and higher disease control rate (83.6% vs 62.7% by RECIST 1.1, p = 0.017; 85.2% vs 62.7% by mRECIST, p = 0.009). In subgroup patients with BCLC stage C, LEN plus PEMBRO provided significantly longer PFS (9.1 vs 4.8 months, p = 0.008), higher ORR (60% vs 33.3%, p = 0.015) and higher DCR (88% vs 60.4%, p = 0.004) by mRECIST criteria. Conclusions: LEN plus PEMBRO provides significantly better ORR, DCR and PFS then LEN monotherapy for patients with unresectable HCC.

e16578 Background: Cabozantinib is a multitarget tyrosine kinase inhibitor and getting attention in these days through its combination with immune checkpoint inhibitors. In this article, we analyze the efficacy of cabozantinib in patients with metastatic ccRCC in Korean who had progression after 1 or more VEGFR TKI therapies. Methods: Seventy-five patients from Jan.2019 to Dec. 2021 at Yonsei Cancer Center who had received cabozantinib treatment in second to fourth line of therapy were retrospectively reviewed. The primary endpoint was PFS. The secondary outcomes were the response rate, disease control rate (DCR), and OS. The evaluable subjects for efficacy were those who had at least one response evaluation. Results: Among 75 patients, 57 (76.0%) were male and median age was 59 years (range 33-81). Median follow up time was 12.1 months. There were 22 (29.3%) patients of second line, 38 (50.7%) of third line and 15 (20.0%) of fourth line of treatment. Median PFS was 5.6 months (95% CI, 4.6-6.6). Median OS was 13.6 months (95% CI, 5.0-22.2). The PFS based on the line of treatment was 4.7 months for second line, 5.6 months for third line and 12.0 months for 4th line. Proportion of patients who were previously treated with ICI was different between treatment line groups and showed increasing trend toward later line; 13.6% of second line, 31.6% of third line, and 66.7% of fourth line, respectively. The objective response rate was 8.0% with 6 patients of partial response. The DCR was 69.3%. The major toxicities were similar with the western population and most of them were less than CTCAE grade 3. Most common grade 3 or 4 AEs were anemia, hand-foot syndrome, fatigue, and stomatitis. There were no grade 5 AEs. Conclusions: Our results demonstrate that cabozantinib is an effective treatment option after first line TKI in Korean ccRCC patients with manageable toxicities. Notably, its tolerability in the advanced line of treatment and synergy with ICIs are suggested in this study despite heterogeneous patients of real world setting. This is the first real world data with cabozantinib in Asian patients.

Unresectable Hepatocellular Carcinoma

Background: Lenvatinib (LEN) has been approved for patients with unresectable hepatocellular carcinoma (u-HCC) since March 2018 in Japan. We performed a retrospective nationwide multicenter study to clarify the clinical characteristics of LEN in real-world practice. Methods: A total of 343 u-HCC patients who received LEN from March 2018 to May 2020 at 23 sites in Japan were registered. Results: During the median observation period of 10.5 months, 143 patients died. In Child-Pugh A (n = 276) and Child-Pugh B (n = 67) patients, the median overall survival (OS) was 21.0 and 9.0 months. The median progression-free survival (PFS) was 8.8 months in Child-Pugh A patients. The objective response rate (ORR) and disease control rate (DCR) according to modified response evaluation criteria in solid tumors (RECIST criteria) were 42.1% and 82.1%. The independent pretreatment factors associated with mortality in all patients were AFP ≥ 400 ng/mL (hazard ratio (HR) 2.00, 95% confidential interval (95% CI) 1.08–2.09, p < 0.0001), modified albumin-bilirubin (ALBI) grade 2b or 3 (HR 1.56, 95% CI 1.09–2.17, p = 0.012), major vascular invasion (HR 1.91, 95% CI 1.26–2.89, p = 0.0022), PS > 0 (HR 1.50, 95% CI 1.09–2.08, p = 0.014), and MTT (molecular targeted therapy) experience (HR 2.22, 95% CI 1.56–3.13, p = 0.00038). In the MTT naïve patients with ALBI grade 1 or modified ALBI 2a and BCLC stage B (n = 68), median OS and PFS were 25.3 and 12.3 months. Liver-related adverse events during LEN were the only significant adverse event associated with OS (HR 2.74, 95% CI 1.93–3.88, p < 0.0001). Among the Child-Pugh A patients with extrahepatic metastasis and no major vascular invasion, median PFS in the patients with bone metastasis was significantly shorter than those with lung or adrenal grand metastasis (6.3 vs. 12.5 months, p = 0.0025). Conclusion: LEN showed a high response rate in real-world practice. Pretreatment factors, including ALBI score, AFP, and major vascular invasion are important in making a treatment strategy for patients with u-HCC. The patients with bone metastasis would be candidates for new therapeutic approaches.

e18731 Background: For advanced non-small cell lung cancer (NSCLC), evidence from clinical trials indicates the superiority of pembrolizumab (P) than chemotherapy (C) in PD-L1 positive patients and superiority of P+C than C among PD-L1 unselected patients. Meta-analysis from different clinical trials stated P+C failed to improve overall survival (OS) or progression-free survival (PFS) compared with P alone. This study used real-world data of PD-L1+ patients with advanced NSCLC to compare treatment effect of P with P+C. Methods: A retrospective analysis of adult patients diagnosed between 2015-2020 with stage IV NSCLC with PD-L1+ and without EGFR/ALK mutation was examined using de-identified Syapse Learning Health Network(LHN). We compared the patients with first-line (1L) treatment of pembrolizumab + carboplatin + chemo (P+C) and patients with 1L treatment of P only (P). Patient characteristics and survival outcomes including real-world OS (rwOS) and real-world time to next treatment (rwTTNT) were collected. Results: 485 patients were included: 231 on P+C and 254 on P. The two groups are similar in race, primary tumor histology and ECOG, and P are older in age and have more female. The median rwOS for P+C is longer than P (13.2 vs 11.0 month), 1 year survival probability is higher (55% vs 49%), but 2 year survival probability is lower (34% vs 39%). Coxph model shows no significant difference between two groups (HR=0.89, 95% CI 0.69-1.14, p=0.34). Subgroup analysis of patients age≥75 shows median rwOS for P+C is shorter than P (8.7 vs 13.2 month), 1 year survival probability is lower (46% vs 51%). Coxph model shows no significant difference between two groups (HR=1.32, 95% CI 0.81-2.16, p=0.27). In each treatment group, the median rwOS for female is longer than male (13.2 vs 7.9 month in P, 15.8 vs 12.2 month in P+C), and 1 year survival probability is higher (52% vs 45% in P, 59% vs 53% in P+C). Coxph model shows no significant difference between female and male (HR=0.81, 95% CI 0.58-1.15, p=0.23 in P; HR=0.90, 95% CI 0.62-1.30, p=0.57 in P+C). Conclusions: Among patients with PD-L1+ advanced NSCLC, there is no significant difference in rwOS for patients with 1L treatment of P+C or P alone.[Table: see text]

Real World Data

Daratumumab is the first anti-CD38 targeting monoclonal antibody approved as monotherapy in multiply relapsed myeloma patients who progressed following prior treatment with proteasome inhibitors (PIs) and immunomodulatory agents (IMiDs). We present real world data on the efficacy of single agent daratumumab in a cohort of 55 multiply relapsed patients treated in the UK. The median age was 72 years, the majority (96%) received ≥ 3 previous lines of treatment; 54.5% were PI-refractory, 76.4% were IMiD-refractory and 47.2% were double refractory; 20% of patients had high-risk (HR) disease. The overall response rate was 49%. After a median follow up of 9.2 months, the median progression-free survival (PFS) for the total cohort was 5.1 months. Patients who achieved a partial response or better (≥PR) demonstrated a significantly longer PFS compared to those with <PR; 9.8 versus 2.7 months, p < 0.001. Double-refractory patients had an inferior PFS compared to single-refractory patients; 2.7 versus 7.4 months, p = 0.084. High-risk disease was associated with significantly shorter PFS compared to standard-risk (SR); 2.3 versus 6.7 months, p = 0.001. The median overall survival (OS) was 15.9 months. Despite a relatively short PFS seen in the double-refractory and high-risk patients; a favourable median overall survival of 12.9 months was achieved in these groups. Patients who achieved ≥PR, those with a previous objective response to PIs or IMiDs and those with SR disease, all benefited from a significantly longer OS which was not reached. A clear benefit in survival is encouraging in this setting of unmet clinical need and limited treatment options.
