Efficacy and Safety of Gefitinib as Third-line Treatment in NSCLC Patients With Activating EGFR Mutations Treated With First-line Gefitinib Followed by Second-line Chemotherapy

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.

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.

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.

15113 Background: First-line chemotherapy for advanced/recurrent gastric cancer has limited efficacy, achieving a median survival time (MST) of about 7 months, while addition of second-line and subsequent chemotherapy may prolong MST to about 11.5 months. In practice, however, about half of patients failing with first-line chemotherapy are unable to receive second-line chemotherapy because of worsening of their performance status (PS), disease progression, or toxicities during protracted first-line chemotherapy. We studied the feasibility of a sequential fixed regimen devised to ensure prompt initiation of second-line chemotherapy after first-line failure. Methods: Between December 2002 and December 2006, patients with advanced or recurrent gastric cancer were enrolled who met the following requirements: 1) major organ function preserved; 2) PS 0–2; 3) presence of at least one evaluable lesion; and 4) written informed consent. The treatment regimen consisted of 3 courses of single-agent S-1 or S-1/cisplatin combination followed by weekly paclitaxel (wPTX). The endpoints of the study were entry to the second-line treatment, time to failure (TTF), and MST. Results: Of 39 patients enrolled, 37 completed first- line S-1. Twenty-eight patients (76%) then received wPTX, 2 non-wPTX chemotherapy, and 6 surgery; only 1 received no additional treatments. Second-line wPTX was followed by a third-line treatment in 23/28 patients (82%). The TTF with the sequential fixed regimen was 7 months. The MST and the 1- and 2-year survival rates in the 37 completing first-line treatment were 14.6 months, 61% and 25%, while those in the 28 switched over to wPTX were 12.5 months, 51% and 17%. Conclusions: Patients with advanced/recurrent gastric cancer treated sequentially with a fixed number of courses of S-1 followed by wPTX may have a good chance of treatment continuation. A sequential fixed regimen may further improve survival of patients with advanced/recurrent gastric cancer only with combinations of currently available drugs.

9035 Background: Several studies show that EGFR-mutant NSCLC patients (pts) gained response to EGFR-TKI treatment again after a TKI free interval. To date, no prospective evaluation of the clinical effects of EGFR-TKI re-challenge in EGFR-mutant NSCLC pts has been performed. Methods: This was a multicenter, open-label, single-arm, phase II study (CTONG1304, NCT01933347). Stage IIIB/IV NSCLC pts with EGFR exon 19del/L858R mutation, who previously benefited from first-line gefitinib treatment followed by second-line chemotherapy, took gefitinib 250mg/d until disease progression or death or intolerable toxicity occurred. Blood samples were dynamically collected for EGFRmutation testing using droplet digital PCR at every visit (from baseline to the end of gefitinib treatment). The primary objective was disease control rate (DCR) at week 8. Secondary objectives were objective response rate (ORR), progression free survival (PFS), and overall survival (OS). Results: From March 2014 to May 2016, 45 eligible pts were enrolled and 43 pts were included in the full analysis set (FAS) for efficacy analysis. Gefitinib re-challenge achieved DCR of 69.8%. ORR was 4.7%. Median PFS and OS were 4.4 and 8.0 months (m) respectively. T790M- subgroup at baseline had higher DCR, longer mPFS and mOS, compared with T790M+ subgroup. EGFRstatus changed significantly after gefitinib re-challenge. Conclusions: Gefitinib re-challenge was an effective option in EGFR-mutant NSCLC pts. T790M negativity is a potentially predictive efficacy biomarker for gefitinib re-challenge. Clinical trial information: NCT01933347. [Table: see text]

e15540 Background: Second-line chemotherapy can now be considered as a proven treatment option for metastatic or locally advanced gastric cancer (AGC). Two global randomized phase III trials (REGARD and RAINBOW) showed that survival benefit was significantly observed in patients treated with ramucirumab (RAM) alone and in combination with weekly doses of PTX, compared with placebo, respectively. The purpose of the study is to evaluate the efficacy and safety of weekly dose of PTX combined with RAM practically as the second-line treatment in Japanese patients with AGC refractory to an S-1-containing chemotherapy regimen. Methods: We conducted a retrospective review of the data of 18 patients with AGC who received more than 2 cycles of PTX/RAM combined chemotherapy as the second-line regimen following S-1-based treatment. The objective response rate (ORR), adverse events, progression-free survival (PFS) and overall survival (OS) were analyzed and compared with PTX monotherapy group. Results: Median number of courses were 5 for the PTX/RAM group and the discontinuation of treatment except for disease progression was found in 2 cases (33.3%). The rates of hematological toxicities of higher than grade 3 were 33.3% in the PTX/RAM group, which were higher than those found in the PTX groups. The tumor responses of the PTX/RAM group were 22% for the ORR and 78% for the DCR, compared with 21% and 48% in the PTX group, respectively. The dose intensities of PTX were 72.4% in the former group. The survival data showed that the MST after second-line exposure was 290 days and the median PFS was 131 days in the PTX/RAM group, compared with 159 days and 90 days in the PTX group, which were not significantly different. Conclusions: PTX/RAM might be one of the best regimens for Japanese patients with AGC as the second-line treatment following S-1-containing chemotherapy.

94 Background: Trastuzumab in combination with platinum-based chemotherapy is the standard first line regimen in HER2 positive advanced gastric cancer. However, there is no data concerning continuation of trastuzumab beyond first line progression. Methods: This retrospective multicenter study include all consecutive patients with HER2 + advanced gastric or gastro-esophageal junction (GEJ) adenocarcinoma who received after progression of trastuzumab plus platinum-based chemotherapy, a second line chemotherapy with irinotecan, taxane or platinum salt, with or without trastuzumab. The prognostic variables with P values ≤0.10 in univariate analysis were eligible for the Cox multivariable regression model. Results: From August 2007 to March 2015, 104 patients were included (median age, 60.8 years; male, 78.8%; PS 0-1, 71.2%) with advanced (metastatic : 99%) gastric (45.2%) or GEJ (54.8%) cancer. All patients had received first line treatment based on trastuzumab plus fluoropyrimidine and cisplatin (n=54; 51.9%) or oxaliplatin (n=50; 48.1%). As second line chemotherapy, 67 patients (64.4%) received FOLFIRI regimen, including 19 who have continued trastuzumab; 23 patients (22.1%) received a taxane regimen (paclitaxel or docetaxel), including 12 with trastuzumab; and 14 patients (13.5%) received a platinum-based chemotherapy (different from that used in first-line), including 8 with trastuzumab. When considering all regimens of second-line chemotherapy, continuation (n=39) versus discontinuation (n=65) of trastuzumab was significantly associated with an increase on PFS (4.4 vs 2.3 months; p=0.002) and OS (12.6 vs 6.1 months; p=0.001). In multivariate Cox model (including ECOG PS, tumor grade, number of metastatic site, and second-line treatment), continuation of trastuzumab was significantly associated with longer PFS (HR=0.56; 95%CI [0.35-0.89]; p=0.01) and OS (HR=0.47; 95%CI [0.28-0.79]; p=0.004). Conclusions: This study suggests that maintenance of trastuzumab plus second line chemotherapy beyond disease progression has clinical benefit in patients with HER2 positive advanced gastric cancer. These results deserve a prospective randomized validation.

4591 Background: Cholangiocarcinoma (CCA) is the most common biliary tract malignancy with an estimated incidence of 8,000–10,000 patients/year in the US. Chemotherapy is the most common second-line treatment with reported outcomes in patients with CCA. Response rates of < 10% and median progression-free survival (PFS) times of ~3–4 months have been reported with second-line chemotherapy regimens, including FOLFOX in the ABC-06 trial. Fibroblast growth factor receptor 2 ( FGFR2) fusions occur in 13–17% of CCA and multiple targeted agents are in development for patients with FGFR2 fusions. To date, the outcome of patients with CCA and FGFR2 fusions receiving standard second-line chemotherapy is unknown. Methods: Patients with advanced CCA and FGFR2 fusions after prior treatment with gemcitabine-based chemotherapy were enrolled in a single-arm phase 2 study (NCT02150967) and received the FGFR1–3 selective TKI infigratinib (previously BGJ398) 125 mg orally qd on d1–21, cycles repeated q28 days until unacceptable toxicity, disease progression, investigator discretion, or withdrawal of consent. A retrospective analysis of a subset of patients who received infigratinib as third- or later-line treatment was performed. Investigator-assessed PFS and best overall response (BOR, per RECIST 1.1) following second-line chemotherapy (pre-infigratinib) and third-line or later-line infigratinib were calculated. Results: Of the 71 patients (44 women; median age 53 years) with FGFR2 fusions enrolled at the time of analysis (datacut 8 August 2018), 37 (52%) were included in this retrospective analysis. Median PFS with standard second-line chemotherapy was 4.63 months (95% CI 2.69–7.16) compared with 6.77 months (95% CI 3.94–7.79) for third- and later-line infigratinib. BOR for second-line chemotherapy was 5.4% (95% CI 0.7–18.2) compared with 21.6% for third- and later-line infigratinib (95% CI 9.8–38.2). Conclusions: Outcomes from second-line chemotherapy in patients with CCA and FGFR2 fusions were similar to those reported in the literature for all patients with CCA regardless of genomic status and remain dismal. Infigratinib administered as third- and later-line treatment resulted in a meaningful PFS and ORR benefit in patients with CCA and FGFR2 fusions. Clinical trial information: NCT02150967 .

Background: The identification of activating mutations in specific genes led to the development of targeted therapies for NSCLC. TKI directed against EGFR-mutations were the first to prove their major efficacy. Medical associations recommend their use as first and second-line metastatic treatments in EGFR-mutated patients. Our objective was to analyze the survival of EGFR-mutated patients treated beyond the second line of treatment. Methods: We performed a longitudinal, retrospective and analytical study at APHP (Assistance Publique Hopitaux de Paris) Saint Louis, Paris, France, from 1 January 2010 to 31 December 2020 (11 years), on EGFR-mutated patients with metastatic NSCLC which received TKI or chemotherapy (CT) in third-line. Results: Out of about 107 EGFR-mutated patients, 31 patients who benefited from TKI or CT in the third line of treatment were retained for this study. The mean age was 60.03 ± 11.93 years and the sex ratio male/female was 0.24. Mutations of exon 19, 21 and 20 were found in 21 (67.7%), 7 (22.6%) and 7 (22.6%) patients, respectively. Third-line treatment was CT for 16 patients (51.6%) and TKI for the 15 remaining patients (48.4%). Osimertinib was the most used TKI in third-line (n = 10/15; 66.67%). The median duration of third-line treatment was 5.37 months (range 0.53–37.6) and the median follow-up duration was 40.83 months (range 11.33–88.57). There was a significant difference in PFS between patients treated with TKI and CT in third-line (p = 0.028). For patients treated with CT in second-line, there was a significant difference of PFS (p < 0.001) and OS (p = 0.014) in favor of the use of TKI in third-line. Conclusions: For patients receiving CT in second-line, TKI appears to be a better alternative in third-line compared to CT. Osimertinib may be used in third line treatment if not used before.

PURPOSE: Since the increased use of first-line chemotherapy for non–small-cell lung cancer (NSCLC), second-line chemotherapy may nowadays be considered for a growing group of patients. Guidelines for second-line treatment have to be developed yet. METHODS: We reviewed the published literature on second-line chemotherapy for NSCLC with emphasis on the role of factors such as pretreatment, response to first-line treatment, and length of disease-free-interval. RESULTS: Thirty-four single-agent-studies and 24 multidrug-studies on second-line treatment were identified. Docetaxel has been studied most extensively and is the only agent that has been studied in randomized phase III trials. Different definitions of sensitivity applied by different authors and conflicting results have been reported about the influence of response to prior chemotherapy. CONCLUSION: Since most patients are treated with a platinum-based regimen in the first line, platinum resistance usually is a major consideration for the use of second-line agents. We argue, however, that a more general definition of drug resistance is more appropriate than resistance to platinum only. Criteria to select NSCLC patients for second-line treatment have not been defined yet. This is also important in light of the upcoming necessity to test new drugs in pretreated instead of treated patients. Guidelines for second-line treatment of NSCLC based on clinical information on drug sensitivity to first-line therapy need to be developed.
