AbstractBackground & AimsThe efficacy and safety of lenvatinib (LEN) as a second/third-line treatment for unresectable hepatocellular carcinoma (HCC) after sorafenib (SOR) therapy remains unknown. We evaluated the outcomes of second/third-line treatment of LEN, investigated the sensitivity of SOR-resistant HCC cell line (PLC/PRF5-R2) to LEN, and their signal transduction pathway by protein array analysis.MethodsWe retrospectively enrolled 57 unresectable HCC patients. Radiologic responses in 53 patients were evaluated by modified Response Evaluation Criteria in Solid Tumors. Active signal transduction pathways in cells were identified by protein array analysis, including 1205 proteins.ResultsPatients comprised 34 tyrosine kinase inhibitor (TKI)-naive (first-line), nine SOR-intolerant (second-line), and ten resistant to regorafenib (third-line). Objective response rates (ORRs) were 61.8% (21/34) in TKI-naive, 33.3% (3/9) in second-line, and 20.0% (2/10) in third-line groups. The overall survival (OS) and the progression free survival (PFS) in the first-line was significantly longer than those in third-line group (p<0.05). Patients with better liver functional reserve (Child score, ALBI grade) exhibited higher ORR and longer OS. LEN was well-tolerated as second/third-line treatment. The IC50 value of LEN against PLC/PRF5-R2 cells (30 μM) was significantly higher than that against PLC/PRF5 cells (6.4 μM). LEN inhibited significantly more signal transduction pathways related to FRS2, a crucial FGFR downstream molecule, in PLC/PRF5 than PLC/PRF5-R2 cells.ConclusionsLEN was active and safe as a second/third-line treatment for unresectable HCC. LEN seems to be more effective for HCC patients with better hepatic reserve function or before TKI-resistance is acquired because of partial cross-resistance to SOR.

485 Background: No information is available on the efficacy and safety of lenvatinib (LEN) as a second/third-line treatment for unresectable hepatocellular carcinoma (HCC) after sorafenib (SOR) therapy. We evaluated the characteristics and the therapeutic efficacy and safety of LEN as a second- and third-line treatment as well as first- treatment for unresectable HCC patients in clinical settings. Moreover, to rationalize these clinical findings in vitro, we assessed the anti-tumor activity of LEN on SOR-resistant cell line and performed a comprehensive phosphorylated protein array analysis associated with 377 signal transduction pathways using SOR-resistant and parental HCC cells. Methods: We retrospectively enrolled 51 unresectable HCC patients. Radiologic responses in 41 patients were evaluated by modified RECIST. Active signal transduction pathways in the cells were identified by protein array analysis, including 1205 proteins. Results: The evaluated patients comprised 25 TKI-naive (first- line), 7 intolerant to SOR (second-line), and 9 patients resistant to regorafenib (third-line). The ORRs were 64% in first-line, 42.8% in second-line, and 22.2% in third-line groups (first-line vs. third-line p< 0.05). The OS in the first-line was significantly longer than that in third-line group ( p< 0.05). Patients with better liver functional reserve (Child score, ALBI grade) exhibited higher ORR and longer OS. LEN was well-tolerated in the second/third-line treatment. The IC50 value of LEN against PLC/PRF5-R2 (30 μM) was significantly higher than that against PLC/PRF5 (6.4 μM). LEN significantly inhibited more signal transduction pathways related to FRS2, a crucial FGFR downstream molecule, in PLC/PRF5 than in PLC/PRF5-R2 cells. Conclusions: Our study indicates that LEN was active and safe in the second/third-line treatment for unresectable HCC. LEN seems more effective for HCC patients with better hepatic reserve function, or before TKI-resistance is acquired because of the partial cross-resistance to SOR.

154 Background: While taxane-monotherapy following fluoropyrimidine plus platinum is recognized as the standard treatment strategy for advanced gastric cancer, triplet chemotherapy with docetaxel, cisplatin and S-1 (DCS) is another option for first-line therapy in Japan. However, efficacy of taxane after DCS therapy has not been sufficiently evaluated. Methods: We retrospectively evaluated the efficacy and safety of taxane-monotherapy after DCS between January 2010 and April 2015 for advanced gastric cancer. The taxane-monotherapy included weekly paclitaxel (PTX) (80 mg/m2, day 1, 8 and 15 of a 28-day cycle) and triweekly nab-PTX (260 mg/m2, day 1). Other selection criteria were: ECOG PS < 2; adequate organ function; no severe ascites; HER2-negative. Results: Thirty of 92 patients who had been treated with DCS received taxane-monotherapy. Fifteen and 15 patients received taxane-monotherapy as the second and third-line treatment, respectively. Patients characteristics of each group (2nd/3rd) were; median age: 64/62 (range 27-75/42-75); ECOG PS ≤ 1: 14/13; number of metastatic sites ≥ 2: 9/12; median taxane-free interval from first-line treatment: 1.6/3.4 (range 0.9-2.3/2.2-8.3) months; median total dose of prior DTX: 349/208 (range 39-844/141-685) mg/m2. Number of patients who received PTX/nab-PTX were 10/5 and 13/2 in the second and third line treatment. Median relative dose intensity of taxane was 96.4% (range 57.6-172.9%) in the second-line, 98.5% (44.0-166.8%) in the third-line group. Response rate and disease control rate were 0% and 37.5% in the second-line, and 0% and 38.5% in the third-line group. Median progression free survival and overall survival were 3.4 and 5.8 months in the second-line group, and 2.0 and 4.5 months in the third-line. Grade 3 or 4 neutropenia, anemia, and anorexia, occurred in 33%, 13% and 13% in the second-line group, and 6.7%, 13% and 6.7% in the third–line group, associated with no treatment related death. Conclusions: It is suggested that taxane-monotherapy has acceptable toxicities but insufficient efficacy in advanced gastric cancer patients after DCS therapy.

Objective: Melanoma is one of the most aggressive cancers and is responsible for the majority of skin cancer deaths, with the presence of metastases prognostic for poor survival. At a time when most cancer incidences are falling, the annual incidence of melanoma has risen as rapidly as 4-6% in many European countries, with a substantial economic burden in advanced stages. The objective of this study is the investigation of treatment pathways and healthcare resource use related to advanced BRAF-mutated melanoma in Greece. Methods: This study is based on the information collected by an expert panel comprising of 3 oncologists of major public and private melanoma clinics around Greece. A 3-round survey was undertaken, according to a modified Delphi method. The treatment phases studied were: pre-progression; disease progression and terminal care. Oncology drug costs, medical visits, laboratory tests, imaging examinations, hospitalization and concomitant medications were the resources considered in the context of the Greek National Services Organization (EOPYY). Results: Τhe most common management scenario (80% of cases) in Greece for patients of stage IV BRAF V600 mutated melanoma was: targeted therapies as first line treatment at 95%, followed by immunotherapies at 100% as second line as well as third line treatment at 65% of cases. The weighted annual cost of treatment was 89.215,78 €, (90%CI:62,451.05; 115,980.51) for first line treatment at list price and around 41.584,50 (90%CI:29,109.15; 54,059.85) based on the negotiated price. At second line, the cost of treatment has been estimated between 15,704.272 (90%CI:10,992.990; 20,415.553) and 19,800.92€, (90%CI: 16,489; 30,622) for the two most common management scenarios for immunotherapies. For third line treatment the cost was 37,778.93 (90%CI 26,445.25; 49,112.61€) for the mostly used management scenario (50% ipilimumab). Conclusions: Μetastatic BRAF mutant melanoma requires prolonged and costly treatment with new therapies shown to substantially increase life expectancy. Identifying the appropriate treatment options in order to optimize health outcomes should be an important priority in healthcare system.

Abstract Purpose: To compare efficacy and safety of BDbortezomib and dexamethasone in multiple myeloma as first-line, second-line or third-line treatment. Patients and methods: 18 patients(pts) treated with BD (bortezomig 1.3mg/m2 on d 1,4,8,11 and dexamethasone 20mg on d 1–4 in a 21-day cycle). Responses were evaluated by the criteria of EBMT but a nCR was included. Adverse events were graded by the WHO criteria. Results: The median age was 52.5 years, and 13 (72.2%) were male. Ig subtypes were IgG, (8 pts, 44.4%), IgA (4 pts, 22.2%), light chain (2 pts, 11.1%), and IgD (1 pts, 5.9%). Durine/Salmon staging: IIA 5.9% (1/18), IIB 5.9% (1/18), IIIA 72.2% (13/18), IIIB16.6% (3/18). BD was administered in first-line (4 pts, 22.2%), second-line (7 pts 38.9%) and third-line (7 pts, 38.9%). The median number of BD cycles was 2.5 (range, 1–6 cycles). 17 pts could be evaluated, overall response was 88.3%, including CR in 2 pts (11.7%), nCR in 5 pts (29.4%), PR in 7 pts (41.2%), MR in 1 pts(5.9%), NC in 1 pts(5.9%), PD in 1 pts(5.9%). Pts in the first-line group received a response of 100%(4/4), including nCR in 1 pts (25.0%), PR in 2 pts (50.0%), MR in 1 pts(25.0%). The second-line group received a response of 100%(7/7), including CR in 1 pts(14.3%), nCR in 3 pts (42.9%), PR in 3 pts (42.9%). Those received BD as third-line or more got a response of 66.7% (4/6), including CR in 1 pts(16.7%), nCR in 1 pts (16.7%), PR in 2 pts (33.3%). Aderse events included diarrhea 44.4% (8/18; grade IV: 2/18), thrombocytopenia 44.4% (8/18; grade III–IV: 7/18), fatigue 44.4% (8/18; grade IV: 1/18), peripheral neuropathy 33.3% (6/18, grade II:1/18), pyrexia 22.2%, infection 16.7% (3/18), headache 11.1%(2/18), parageusis 11.1%(2/18), hypotension 5.9%(1/18), hypoglycemia 5.9%(1/18) while combining with glipizide. The median time to minimum counts of platets was 14 days. The median time to most serious peripheral neuropathy appeared after treatment of 3 cycles. In 1 pts the therapy was disrupted by toxicity. Conclusion: BD demonstrated better response as first-line or second-line therapy than as third or more line therapy. Toxicities were torelated and manegable. There were no treatment related deaths.

e16080 Background: Patients with advanced gastric or gastro-esophageal junction cancer have poor prognosis after progression on first-line chemotherapy. We investigated to combine second-line chemotherpy with third-line drugs, apatinib and anti-PD-1 antibody in these patients. Methods: This study is a single center, exploratory study in China. Eligible patients are adults with histologically confirmed advanced gastric or GEJ adenocancinoma, who were failure of first-line or second-line chemotherapy. Subjects receive chemotherapy, pacitaxol or iritecan (investigator choice), apatinib 250mg po qd, sintilimab 200mg ivd q3w. Response was assessed every 6 weeks. (RECIST version1.1) Primary endpoint was progression free survival (PFS). Results: Between May 30, 2019 and November 5, 2020, a total of 26 patients were enrolled in this study, and 4 (15.4%) patients were failure of second-line chemotherapy. There were 21 males and 5 females, and the median age was 61. The total number of treatment cycles was 140 and the median number was 5.5. Among 24 patients who were evaluated, partial response (PR) was obtained in 12 cases, stable disease (SD) in 8 cases and progressive disease (PD) in 4 cases. Objective response rate was 50.0%，and disease control rate was 83.3%. The median PFS was 7.06 months (95% CI 5.52-8.60), and the median overal survival has not yet been reached. The most common adverse events (AE) were leukopenia (61.5%), anemia (57.7%), neutropenia (53.8%), proteinuria (42.3%), alopecia (42.3%), hypothyroidism (38.5%), elevated alanine aminotransferase (34.6%), elevated aspartate aminotransferase (34.6%) and elevated alkaline phosphatase (34.6%), but most of them were grade 1 or 2, and the most common grade 3 or 4 treatment-related adverse events was neutropenia (11.5%). Conclusions: Chemotherapy, plus apatinib and sintilimab demonstrated promising activity and manageable safety profile as second- even third-line treatment in advanced gastric or GEJ cancer.

Background: Helicobacter pylori eradication containing the potassium-competitive acid blocker, vonoprazan, achieves a higher eradication rate than therapy with proton pump inhibitors (PPIs). Because vonoprazan is mainly metabolized by CYP3A4/5, CYP genotype may affect the eradication rate. We investigated the influence of antibiotic susceptibility and CYP3A4/5 and CYP2C19 genotypes on the eradication rates. Methods: A total of 307 Japanese who were genotyped for CYP3A4 *1/*22, CYP3A5 *1/*3 and CYP2C19 *1/*2/*3/*17, and investigated for susceptibility to antimicrobial agents, received vonoprazan-containing regimens: (1) With amoxicillin and clarithromycin as the first-line treatment; (2) with amoxicillin and metronidazole as the second-line treatment; or (3) with amoxicillin and sitafloxacin as the third-line treatment. Results: The eradication rate was 84.5% (95% confidence interval [CI]: 78.9–89.1%) using first-line, 92.6% (95% CI: 82.1–97.9%) using second-line and 87.5% (95% CI: 73.1–95.8%) using third-line treatment. Infection with clarithromycin-resistant strains was a predictive factor for failed eradication (odds ratio: 5.788, 95% CI: 1.916–17.485, p = 0.002) in multivariate analysis. No significant differences were observed in the eradication rate of regimens among CYP3A4, CYP3A5 and CYP2C19 genotypes. Conclusions: Genotyping for CYP3A4 *1/*22, CYP3A5 *1/*3 and CYP2C19 *1/*2/*3/*17 before vonoprazan-containing eradication treatment may not be useful for predicting clinical outcomes.

ObjectiveThe objective of this study was to evaluate the characteristics and outcomes of patients treated for gestational trophoblastic neoplasia (GTN) with second-line 5-day dactinomycin after failed first-line 8-day methotrexate.MethodsFrom 1999 to 2017, patients with methotrexate resistant GTN treated with second line dactinomycin were identified at the French Trophoblastic Disease Reference Center. Using univariate and multivariate analysis, we identified significant predictive factors of second line dactinomycin failure.ResultsA total of 877 GTN patients were treated with first-line 8-day methotrexate, of which 103 required second-line 5-day dactinomycin for methotrexate failure. Complete response was observed in 78 patients (75.7% [95% confidence interval, 66.3–83.6]; P < 0.0001), whereas 25 needed third-line treatment, 13 for dactinomycin resistance and 12 for post–dactinomycin relapse. Overall survival of patients treated with dactinomycin was 100%. An interval of greater than or equal to 7 months between antecedent pregnancy termination and methotrexate initiation was a predictive factor significantly associated with second-line dactinomycin failure in multivariate analysis (exact odds ratio, 9.17 [95% confidence interval, 1.98–50.70]; P = 0.0029). No grades 4 and 5 adverse effects were experienced and the most common toxicity being grade 1 nausea (14.6%).ConclusionGiven a 75.7% complete response rate in methotrexate failed low-risk GTN patients treated with second-line dactinomycin and an overall survival rate of 100% after third-line treatment, the use of dactinomycin should be favored as second-line, regardless of human chorionic gonadotropin level at the time of dactinomycin initiation. However, an interval between the termination of the antecedent pregnancy and methotrexate initiation longer than 6 months should encourage considering alternative therapeutic strategies.

Background: Antiangiogenic agents have been shown to stimulate the immune system and cause synergistic effects with chemotherapy. Effects might be even stronger after immune-checkpoint-inhibitor (ICI) therapy. The purpose of this analysis was to evaluate the efficacy of ramucirumab plus docetaxel (R + D) as third-line treatment after failure of a first-line platinum-based chemotherapy and a second-line ICI treatment in patients with non-small-cell lung cancer (NSCLC) stage IV. Methods: Retrospective data were collected from 9 German thoracic oncology centers. Only patients who had received at least 1 cycle of third-line R + D were included. The numbers of cycles, objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were investigated. Results: Sixty-seven patients met the criteria for inclusion. Third-line treatment with R + D achieved an ORR of 36% and a disease control rate (DCR) of 69%. Median PFS for third-line therapy was 6.8 months with a duration of response (DOR) of 10.2 months. A median OS of 29 months was observed from the start of first-line therapy with a median OS of 11.0 months from the start of third-line treatment. No unexpected toxicities occurred. Conclusion: R + D is a highly effective and safe third-line treatment after failure of second-line programmed cell death protein 1/programmed cell death-ligand 1 (PD1/PD-L1)-derived ICI therapy irrespective of NSCLC histology. As there may be synergistic effects of second- and third-line treatments, this sequence is a very suitable option for patients not treated with first-line ICI. In addition, R + D should continue to be investigated as a second-line treatment option after failure of chemotherapy plus ICI in the palliative first–line treatment.

e15794 Background: First-line and second line treatment for advanced pancreatic adenocarcinoma typically involves therapy with gemcitabine plus nab-paclitaxel, FOLFIRINOX or as per the recent phase III trial (NAPOLI-1), the combination of nal-irinotecan with 5-fluorouracil and leucovorin. Despite these advances, there remains minimal amount of data regarding the options for, or efficacy of, third-line treatment in these patients. We have previously reported our experience of twenty patients who received effective third-line therapy with gemcitabine plus nab-paclitaxel retreatment after receiving FOLFIRINOX as second-line treatment. This retrospective analysis assessed the updated data of the use of gemcitabine plus nab-paclitaxel as a third-line treatment option in a single hospital setting. Methods: We conducted a retrospective analysis using an electronic database of patients with locally advanced or metastatic pancreatic adenocarcinoma who received first-line gemcitabine and nab-paclitaxel, second line FOLFIRINOX and third-line retreatment with gemcitabine and nab-paclitaxel between January 2013 and December 2018. All patients had an ECOG performance status of 2 or less. Overall survival (OS) was estimated by the Kaplan-Meier method. Results: Twenty-six patients were reviewed. Median age of 73 (range, 45 – 81). 73% of the studied patients had locally advanced cancer at diagnosis. The median OS from diagnosis was 39.0 months (95% CI, 34.0 – 66.0). The median OS from third-line re-initiation of gemcitabine plus nab-paclitaxel was 18.0 months (95% CI, 9.0 – 32.0). Conclusions: This is one of the first retrospective studies to show the efficacy of third-line treatment with gemcitabine plus nab-paclitaxel in advanced pancreatic cancer. It demonstrated that retreatment with gemcitabine plus nab-paclitaxel is feasible, tolerable and effective in patients with a good performance status. We suggest a formal phase 3 study to confirm our data and potentially establish a formal new standard of care for third line chemotherapy in this previously disadvantaged group.
