9013 Background: Au is a novel, irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI) with favorable pharmacologic properties that selectively inhibits both EGFR sensitizing and resistance mutations. Au has been approved in China for treatment of patients (pts) with EGFR mutant NSCLC with EGFR T790M upon progression of disease on previous EGFR TKIs (Proc. AACR 2020, Abstract CT190). This Phase III trial assessed the efficacy and safety of Au versus G as initial treatment of patients with advanced NSCLC with EGFRm. Methods: Pts with previously untreated metastatic or locally advanced NSCLC and EGFR exon 19 deletion or L858R were randomly assigned in a 1:1 ratio to receive either Au (110 mg once daily) or G (250 mg once daily). The primary endpoint was progression-free survival (PFS) by RECIST v1.1 per investigator assessment. At 262 PFS events, the study had 90% power to detect a PFS HR = 0.67. Secondary endpoints included overall survival (OS), objective response rate (ORR), duration of response (DoR) and safety. Results: Between Nov 30, 2018 and Sept 6, 2019, 429 patients across 53 sites in China were enrolled and randomized. Pt. characteristics were well-balanced. At the planned final event-driven PFS analysis, Au significantly prolonged PFS (median 19.3 vs 9.9 months, HR 0.46, p-value <0.0001). DoR was also significantly prolonged with Au. Median OS has not been reached. Efficacy and relevant safety results are summarized in Table. Despite a significantly longer duration of treatment (median 463 vs 254 days), Au was associated with a lower incidence of rash, diarrhea, AST/ALT increase, and treatment related serious adverse events (SAEs) (4.2% vs 11.2%). Au was associated with more frequent events of CPK increased, platelet count decreased, and neutrophil count decreased, which were predominantly low grade. Conclusions: Au significantly prolonged PFS and DoR compared to G as first-line therapy in pts with advanced NSCLC with EGFRm. Au demonstrated a favorable safety profile, especially regarding toxicities mediated by wild-type EGFR. These results establish Au as a promising option for advanced NSCLC with EGFRm. Clinical trial information: NCT03849768. [Table: see text]

LBA7511 Background: INFORM (a phase III, randomized, multicenter, parallel group study; NCT00770588 ) investigated the efficacy, safety and tolerability of gefitinib (G) vs. placebo (P) as maintenance therapy in pts with locally advanced/metastatic NSCLC following standard first-line platinum based chemotherapy. Methods: Pts (≥18 years, with stage IIIB/IV NSCLC and WHO performance status 0-2) had completed 4 cycles of first-line platinum based doublet chemotherapy without progression/unacceptable toxicity. Pts were randomized 1:1 to G 250mg/day or P on discontinuation of first-line therapy. Progression-free survival (PFS; primary endpoint) was assessed in the intent to treat population (Cox proportional hazards adjusted for histology [adenocarcinoma vs. non-adenocarcinoma], smoking status [never-smoker vs. smoker], EGFR mutation status [positive vs. negative vs. unknown] and best response to first-line chemotherapy [complete response/partial response vs. stable disease]). PFS was considered superior with gefitinib if the G:P hazard ratio (HR) upper confidence interval (CI) was <1.00. Secondary endpoints included overall survival (OS), objective response rate, disease control rate, symptom improvement and tolerability. Results: 296 pts (n=148 G, n=148 P) were randomized (27 centers in china; 26 September 2008-10 August 2009). PFS data cutoff on 24 January 2011. Median duration of follow-up was 16.8 months: 91% pts progressed; 59% deaths. Demography was balanced between treatments; overall, 54.1% pts were never-smokers, 70.6% had adenocarcinoma, and 40.9% were female. For G vs. P, PFS HR=0.42; 95% CI 0.32-0.54; p<0.0001; median PFS 4.8 vs. 2.6 months. Most common AEs (any grade) with G were rash (49.7%), diarrhea (25.2%), and ALT increase (21.1%) which were generally mild/moderate. Overall incidence of serious AEs: G (6.8%); P (3.4%). Other secondary endpoint data (including OS and biomarkers) will be presented. Conclusions: PFS was significantly longer with G compared with P as maintenance therapy in Chinese patients with locally advanced NSCLC.

TPS4648 Background: Gastric cancer is the fourth leading cause of cancer death worldwide. Capecitabine + oxaliplatin (CAPOX) is a standard first-line treatment for advanced gastric cancer. Claudin (CLDN)18.2 has emerged as a promising targetable biomarker. In healthy tissue, CLDN18.2, a tight junction protein, is confined to gastric mucosa (ie, cells in the pit and base regions of gastric glands). Upon malignant transformation, structural loss in gastric or gastroesophageal junction (G/GEJ) adenocarcinoma cells may allow antibodies more access to previously unavailable CLDN18.2. Zolbetuximab is a chimeric IgG1 monoclonal antibody that specifically binds to CLDN18.2 and mediates cell death through antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity. Results of a phase 2 study (NCT01630083) showed prolonged survival of patients with CLDN18.2-positive (CLDN18.2+) advanced G/GEJ adenocarcinoma treated with zolbetuximab + epirubicin, oxaliplatin, and capecitabine (EOX) vs EOX alone. Methods: This phase 3, double-blind, placebo-controlled study (NCT03653507) will enroll ~500 adult patients from global sites. Patients are required to have CLDN18.2+/HER2− locally advanced unresectable or metastatic G or GEJ adenocarcinoma that is radiographically evaluable per RECIST v1.1. Patients are not permitted to have received prior treatment with chemotherapy for advanced or metastatic G or GEJ adenocarcinoma. Patients will be randomly assigned 1:1 to receive either zolbetuximab plus CAPOX or placebo plus CAPOX. Randomization will be stratified by region (Asia vs non-Asia), number of metastatic sites (0 to 2 vs ≥3), and prior gastrectomy (yes vs no). Zolbetuximab will be administered at a loading dose of 800 mg/m2 IV on Cycle 1 Day 1 followed by 600 mg/m2 IV every 3 weeks. Central testing of tumor tissue will determine CLDN18.2 and HER2 status (if unknown); patients will be considered CLDN18.2+ if ≥75% of tumor cells demonstrate moderate-to-strong membranous immunohistochemical staining. The primary objective is to compare progression-free survival between treatment arms. Secondary endpoints are overall survival; objective response rate; duration of response; and the safety/tolerability, pharmacokinetics, and immunogenicity of zolbetuximab. As of January 31, 2020, 127 sites were active and open to enrollment. Clinical trial information: NCT03653507 .

e17047 Background: For relapse or metastatic SCCHN the standard treatment is the combination of cisplatin and 5FU that showed higher response rate than methotrexate but similar overall survival. Cetuximab demonstrated in a phase III (N Engl J Med. 2008;359:1116) its efficacy and paclitaxel showed efficacy in a phase II study (Cancer. 1998;82:2270). The objective of this study was to evaluate paclitaxel (P) in our institution in various situations. Methods: We retrospectively reviewed 56 pts with relapse or metastatic SSCHN treated with P in a single institution in Lyon (France) between June 2002 and February 2008. P was administered in first line for locally advanced disease, in first line for relapsed or metastatic disease, or in second or more line. P was administered q1w or q3w, alone or in combination with carboplatin or cetuximab. Results: Median age was 59 years (36–84) at the beginning of paclitaxel. Localizations of primitive tumor: oral cavity (14%), oropharynx (30%), hypopharynx (39%) larynx (7%), rhinopharynx (4%), or other (6%). All patients received adequate initial treatment with surgery and/or radiotherapy, 47% had have neoadjuvant chemotherapy (71% with cddp-5fu, but 5 pts received P). Five patients received P as neoadjuvant treatment. Among 52 evaluable patients, 33 received P in first line of treatment after relapse, 12 in second line. Monotherapy was administered to 20 patients and 22 received P combined with carboplatin, and 1 with cetuximab. For all patients, objective response rate (OR) was 30.8% (95% CI 18.7–45.1%). In first line of relapse, OR was 39.4% (95% CI 22.9–57.9%) and 16.7% (95% CI 2.1–18.4%) in second line. In monotherapy OR was 30.0% (95% CI 11.9–54.3%) and 36.4% (95% CI 17.2–59.3%) in combination with carboplatin. The overall survival (OS) of all patients was 6.3 months (95% CI 3.9–7.9 m), and 7.7 m (95% CI 3.9–11 m) and 5.2 m (95% CI 2.8–7.9 m) in first and second line, respectively. There is no difference in OS between monotherapy and combination: 6.1 m (95% CI 3.9–7.9 m) and 5.3 m (95% CI 3.9–7.9 m), respectively. Conclusions: P did not improve overall survival but showed interesting response rate in relapsed patients who are often symptomatic. Recent studies suggest high potentialities in combination with EGFR inhibitors. No significant financial relationships to disclose.

e15151 Background: We examined whether 133 germline polymorphisms (SNPs) in 15 candidate genes (CSF1R, IL8RA, TLR4, IL10, IL10RA, CTLA4, IL2, IL2RA, TGF b1, ICOS, IL13, IL13RA2, IFNgR, IL15 and IL15RA) would predict clinical outcome in the ACCORD-12 phase III trial which randomly compared neoadjuvant radiotherapy (RT) plus capecitabine (CAP45) with dose-intensified RT plus capecitabine and oxaliplatin (CAPOX50) in T3-4 Nx M0 resectable rectal cancer. Methods: A candidate-gene association study was conducted in 316 patients (n = 161 in the CAPOX50 and n = 155 in the CAP45 arm). The primary end-point was tumor response according to the Dworak score in each arm. Logistic regressions were used to assess univariate/multivariate associations. The Storey and Tibshirani method based on the control of false discovery rate was used ( q-value < 0.10 (adjusted p-value) considered as true discovery). Multivariate models adjusted on treatment arm and T stage were performed to determine prognostic and predictive values of SNPs for tumor response. Results: In univariate analysis, two SNPs in IL2RA (rs11256456: OR = 5.1 [2.38; 11] and rs706781: OR = 4.2 [1.98 ; 8.74]) were significantly associated with the Dworak score in the CAP45 arm, and one in IL2RA the CAPOX50 arm (rs2104286: OR = 0.11 [0.01 ; 0.90]. All were confirmed in the multivariate analysis. A significant haplotypic effect was observed in the CAP-45 arm (p = 0.0001). Interaction was significant for IL2RA rs11256456 ( p= 0.03) and rs706781 ( p= 0.002) and no significant for IL2RA rs2104286 ( p= 0.722), suggesting a predictive deleterious effect the first two ones for response to oxaliplatin-based chemoRT, and a prognostic effect of the third one for response to chemoRT (+/- oxaliplatin). None of the three IL2RA SNPs were correlated with survival in the multivariate analysis. Conclusions: This pharmacogenetic analysis shows that SNPs in IL2RA have a significant association with response to chemoRT with capecitabine in patients with locally advanced rectal cancer. Their predictive effect may identify patients in whom oxaliplatin addition to chemoRT is deleterious.

e21703 Background: Anlotinib is an oral VEGFR, FGFR, PDGFR and c-Kit tyrosine kinase inhibitor, which can prolong both PFS and OS of refractory advanced NSCLC patients in phase III trial: ALTER0303. The combination of docetaxel and ramucirumab/nintedanib had been demonstrated activity in the second line therapy setting for NSCLC. We performed ALTER-L018 to assessed the safety and efficacy of anlotinib with docetaxel in EGFR-wild type refractory advanced NSCLC (NCT03624309). Methods: Patients (pts) with EGFR-wild type refractory advanced NSCLC, who failed to first-line platinum-based chemotherapy, were randomized to group A(anlotinib: 12mg QD from day 1 to 14 of a 21-day cycle +docetaxel: 75mg/m2 Q3W) and group B(docetaxel: 75mg/m2 Q3W). The primary end points is PFS, and secondary end points include OS, ORR, DCR and safety. Results: Between January and December 2019, 36 pts were enrolled at 10 institutions in Hunan China, with 31(15 in group A, 16 in group B) of these individuals being evaluable for treatment efficacy and safety. Pt characteristics(group A/ group B): median age: 55(39-70)/57(44-67); male: 73%/81%; non-squamous NSCLC: 86%/75%. Median PFS were 5.3 months (95%CI:2.76-7.85) in group A and 2.3 months (95%CI, 1.14-3.46) in group B (HR 0.42; 95% CI:0.16-1.13; p = 0.047); In group A and B, ORR and DCR were 26.67% versus 0%(p = 0.043), 60.00% versus 31.25%(p = 0.16), respectively. Among 31 pts, 89% of treatment-related AEs (TRAEs) were grade 1 or 2, and the most common TRAEs in group A were hand-foot syndrome, pruritus and insomnia of 13%(2/15) each; in group B were alopecia, constipation and anemia of 12%(1/16) each. Toxicities≥grade 3(TRAEs) included: neutropenia, leukopenia, diarrhea and hrombocytopenia, 6.6%(1/15) each in group A. There was 1 grade 5 AE in group A. Conclusions: This combination of anlotinib and docetaxel with significant difference PFS prolonging and manageable safety profile, is a viable option in relapsed NSCLC, should be considered following progression on platinum-based chemotherapy. It will be further explored in a randomized phase III trial. Clinical trial information: NCT03624309.

TPS5094 Background: In RCC, the Von Hippel-Lindau ( VHL) tumor suppressor gene is inactivated in most cases, resulting in the accumulation and overactivation of HIF-2α. HIF-2α is a key oncogenic driver in RCC and is involved in the activation of genes associated with angiogenesis, tumor progression, and metastasis, such as vascular endothelial growth factor A ( VEGFA), cyclin D1, and CXCR4. MK-6482 is a potent and selective small molecule inhibitor of HIF-2α, and it has shown antitumor activity in a phase 1/2 study in patients with previously treated advanced ccRCC. Methods: The current study (NCT04195750) is a phase 3, open-label, multicenter, randomized, active-controlled trial to compare the efficacy and safety of MK-6482 with everolimus in patients with previously treated advanced ccRCC. Adults aged ≥18 years will be eligible if they have unresectable, locally advanced, or metastatic ccRCC; have measurable disease per RECIST v1.1; and received ≤3 prior systemic regimens, which must include a PD-1/PD-L1 inhibitor (≥2 doses) and a VEGF-targeted therapy, for locally advanced or metastatic RCC. Approximately 736 patients will be randomly assigned 1:1 to receive MK-6482 120 mg orally once daily or everolimus 10 mg orally once daily. At randomization, patients will be stratified by International Metastatic RCC Database prognostic scores (0 vs 1-2 vs 3-6) and by the number of prior anti-VEGF–targeted therapies received for advanced RCC (1 vs 2-3). Responses will be assessed by CT or MRI per RECIST v1.1 by blinded independent central review at week 9 from the date of randomization, then every 8 weeks through week 49, and then every 12 weeks thereafter. Treatment will continue until documented disease progression, withdrawal of consent, or other discontinuation event. Dual primary endpoints are progression-free survival per RECIST v1.1 and overall survival. Key secondary endpoints include objective response rate, duration of response, patient-reported outcomes, and safety. Clinical trial information: NCT04195750 .
