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.

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.

e15613 Background: Despite high response rates (RRs) with first-line platinum-based chemotherapy in advanced urothelial carcinoma (UCC), treatment after first-line failure remains unclear. The present multi-center phase II trial evaluated the tolerability and efficacy of weekly docetaxel as second-line chemotherapy for UCC. Methods: Between Aug 2010 and Sep 2012, 31 patients with measurable UCC, progressive after one prior platinum-based chemotherapy for advanced disease, were treated with docetaxel 30 mg/m2 on days 1 and 8. Treatment was repeated every 21 days until disease progression or unacceptable toxicity. The primary endpoints were the RR, progression-free survival (PFS), and safety. To detect a 20% difference in RR (6% vs. 26%), 28 eligible patients were required. Results: All 31 patients were previously treated with gemcitabine/platinum and had Bellmunt risk of one or more. The patients’ median age was 64 years (range, 40 to 79) and 31 (100%) patients had an ECOG performance status of 1. A total of 106 (median, 2; range, 1 to 16) chemotherapy cycles were delivered. Although fatigue (13%) and anorexia (6%) were the most frequently observed grade 3 or 4 toxicities, safety profiles were generally mild and manageable. One patient developed prolonged thrombocytopenia which led to treatment discontinuation but was resolved thereafter. In an intent-to-treat analysis, two (6%) patients achieved objective response, which maintained for 3.0 to 7.8 months. Eight patients experienced disease stabilization, resulting in a disease control rate of 32%. The median PFS and overall survival were 1.4 (95% CI, 1.3 to 1.6) and 9.6 (95% CI, 7.8 to 11.4) months, respectively. Conclusions: Second-line chemotherapy with weekly docetaxel was well tolerated but demonstrated modest antitumor activity in patient with advanced UCC who had progression after first-line platinum-containing regimen and poor prognostic factors. Clinical trial information: NCT01711112.

216 Background: The androgen receptor machinery remains the ultimate target of NAs in mCRPC post-DOC, abiraterone acetate (AA), cabazitaxel (CAB), and enzalutamide (ENZ). It is postulated that some mechanisms of resistance may be common to all NAs. This may be crucial in planning their sequential use, mainly when a PRes to one of them is observed. The present study assessed the activity of NAs in pts who previously experienced a PRes to another NA administered after DOC. Methods: We collected data of pts who received sequentially two NAs after DOC in 32 Italian hospital. For each pt we recorded the clinical outcomes of all treatments received after DOC. For the study purpose, we consider with PRes all pts progressing within 3 months after second line NA start. All other pts were considered as without PRes. Results: A consecutive series of 271 mCRPC pts, median age 71 yrs (46-91), with bone (89%), nodal (56%) or visceral (19%) mets, was collected. All pts received NAs as second line after DOC (AA 54% – CAB 34%– ENZ 12%) and 54 (20%) showed a PRes. Among these, third line treatment [AA (31%), CAB (42%), and ENZ (27%)], produced a biochemical and an objective response rate of 11% in both cases, with a median progression free survival (PFS) and a median overall survival (OS) of 4 mos and 8 mos, respectively. No statistically significant differences were observed in terms of clinical outcomes on the basis of NA sequences (see Table). Conclusions: It appears from this preliminary data, that the activity of NAs in pts showing a PRes to second line NAs is very limited, regardless the NA is administered. [Table: see text]

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]

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 .

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.

e16151 Background: IV NVB plus hydrocortisone (HC) compared with HC alone resulted in improved clinical benefit, progression-free survival (PFS) and PSA response rate in HRPC. The oral formulation of NVB avoids the side effects associated with the IV injection, may reduce administration and toxicity-related costs and is easy to administer. Due to these advantages, single agent oral NVB treatment could be considered as an optimal option for patients (p) with HRPC previously treated with a taxane or as first-line treatment when a taxane is not indicated. We retrospectively evaluated efficacy and toxicity or oral NVB administered as single agent as first or second-line chemotherapy of metastatic HRPC. Methods: Retrospectively data was collected from p with metastatic HRPC treated with oral NVB 80 mg/m2 days 1 and 8, with a prior test of myelosensitivity at 60 mg/m2 for the first cycle, plus prednisone 10 mg/day. Patients had received a taxane as first-line treatment or had a documented contraindication to receiving docetaxel. 1 cycle was equivalent to a 3-week period. Results: Data on 55 p treated in 11 Spanish centres were included for assessment. Median age was 72.5 years (range 54–86). ECOG PS 0, 17%; 1, 66%; 2, 17%. Median PSA 75 ng/mL. Prior taxane chemotherapy, 87%. Median number of cycles was 4 (range 1–6). 53.8% of p could escalate oral NVB to 80 mg/m2. 221 cycles were performed, 4.1% were delayed and 3.2% had a dose reduction. Grade 3–4 events were infrequent and mainly haematological: neutropenia (5.5% of p), anemia (3.6%), pain (3.6%), infection (1.8%), asthenia (1.8%), respiratory (1.8%). No febrile neutropenia was reported. 49 p were evaluable for PSA response rate; complete plus partial response was observed in 20.4% (95% CI: 10.2% - 34.3%) and PSA stable was reported in 40.8%. 29 p were evaluable for measurable disease; among them, 20.7% presented partial response and 44.8% stable disease. Median follow-up was 4.3 months. Survival status: 49 p (89.1%) are alive and 6 p (10.9%) died. Conclusions: Oral NVB is a safe and active regimen in previous chemotherapy treated HRPC. For those p who can not receive a taxane as first-line therapy, oral NVB can also be considered as an effective first-line treatment. No significant financial relationships to disclose.

Patients had received either a taxane as 1st-line treatment or had a documented contraindication to receiving docetaxel. 1 cy was equivalent to a 3-week period. Results: Data on 67 p treated in 13 Spanish centres were included. Median age 73 years (range 54-86). ECOG PS 0, 16.4%; 1, 56.7%; 2, 11.9%. Median PSA 88.9 ng/mL. Prior chemotherapy, 58.2%. Median number of cy was 4 (range 1-6). 56.9% of p could escalate NVBO to 80 mg/m2. 265 cy were performed, 9.1% were delayed and 2.3% had a dose reduction.

No febrile neutropenia was reported. PSA response rate 16.1%, PSA stable was reported in 41.9%. 39 p were evaluable for measurable disease; among them, PR 17.9%, SD 48.7%. Median follow-up, 7.1 months. Median overall survival, 11 months [95% CI: 7.3-14.7]. Median PFS, 2.9 months [95% CI: 2.2-3.6]. Conclusions: NVBO is a safe and active regimen in previous chemotherapy treated HRPC. For those p who cannot receive a taxane as first-line therapy, NVBO can also be considered as an effective first-line treatment.
