TPS178 Background: Ramucirumab, a human IgG1 monoclonal antibody directed to the ectodomain of VEGFR-2, prevents ligand binding to the receptor, blocking activation of downstream receptor-mediated pathways. Ramucirumab has demonstrated significant improvement in overall survival (OS) and progression-free survival (PFS) in 2 phase III registration studies (REGARD, RAINBOW) in patients in second-line treatment of gastric cancer. This global phase III trial will compare PFS in patients with HER2-negative, metastatic gastric or GEJ adenocarcinoma receiving ramucirumab with cisplatin/capecitabine (or 5-FU) versus placebo with cisplatin/capecitabine (or 5-FU) as first-line treatment. The trial is conducted in 137 sites in the Americas, Europe and Japan and is currently open to enrollment. Methods: Eligible patients will be randomized to receive ramucirumab (8mg/kg on days 1 and 8, based upon population pharmacokinetic modelling) or placebo with cisplatin/capecitabine every 21-day cycle until disease progression, unacceptable toxicity, or other withdrawal criteria are met. The primary endpoint is PFS; OS is the key secondary endpoint. Efficacy will be considered at 3 analysis points: futility analysis for PFS, primary analysis of PFS & final analysis of OS. A gatekeeping strategy will be used to assess PFS and OS. The OS endpoint will only be tested if the PFS test is significant to control Type I error at 5% across both endpoints. An exposure/safety analysis will be done after 60 patients have started the 3rd cycle. The study has 90% power to demonstrate a PFS advantage assuming HR = 0.70 and 80% power to demonstrate an OS advantage assuming HR = 0.77. Other secondary endpoints include PFS2 (the time from randomization to disease progression after the start of additional systemic anticancer treatment, or death from any cause, whichever occurs first), objective response rate, safety and quality of life. As of 9/11/2015, 128 patients have been enrolled in 19 countries. The 1st exposure/safety analysis is underway. Clinical trial information: NCT02314117.

Cetuximab metastatic colorectal cancer strategy (ERMES) study: A phase III randomized two arm study with FOLFIRI + cetuximab until disease progression compared to FOLFIRI + cetuximab for 8 cycles followed by cetuximab alone until disease progression in first-line treatment of patients with RAS and BRAF wild type metastatic colorectal cancer.

TPS810 Background: The optimal duration and content of first-line therapy in mCRC pts once they have achieved objective response is controversial. In the FIRE-3 trial, ETS was significantly associated with PFS and OS. Based on this evidence it can be hypothesized that once this goal has been achieved, further exposure to combined antineoplastic treatment may not result in improvement or preservation of such result but only in an increase of toxicity. We designed a strategy study to compare FOLFIRI + cetuximab until PD to FOLFIRI + cetuximab for 8 cycles followed by cetuximab alone until PD in first line treatment of RAS/BRAF WT mCRC pts. Methods: This is a multicenter, open-label, randomized phase III trial. Untreated and unresecteble RAS/BRAF WT mCRC pts were randomized 1:1 to receive Cetuximab (400 mg/mq w1 and then 250 mg/mq weekly) + FOLFIRI until PD (standard arm) or Cetuximab (400 mg/mq week 1 and then 250 mg/mq weekly) + FOLFIRI for 8 cycles followed by Cetuximab monotherapy until PD (experimental arm). Tumor assessment is planned every 8 weeks. The objective of the study is to demonstrate a not inferior efficacy and a better toxicity profile for the experimental treatment compared to the standard treatment. The co-primary endpoints are PFS and incidence of G 3-4 AEs. Secondary endpoints are OS, ORR, ETS (8 weeks) and safety. A prospective multiple gene mutation analysis by NGS of both tumor tissue and blood will be performed to find potential predictive factors and surrogate markers of treatment efficacy. The two co-primary endpoints will be compared between the two arms using a fixed-sequence testing procedure to control for the family-wise type I error rate of 0.05 in a strong sense. This sequence considers that a reduction of grade 3-4 AEs is only of relevance, if non-inferiority is shown regarding PFS. 600 evaluable pts will be enrolled and randomized. Study recruitment started on January 2015, currently 139 pts have been randomized. Clinical trial information: NCT02484833.

4 Background: Andecaliximab (ADX) is a monoclonal antibody that inhibits matrix metalloproteinase 9, an extracellular enzyme involved in matrix remodeling, tumor growth, and metastasis. A phase I/Ib study of mFOLFOX6 + ADX revealed encouraging antitumor activity in patients (pts) with gastric or gastroesophageal junction (GEJ) adenocarcinoma (median first-line, progression-free survival [PFS] of 9.9 months). Methods: This phase 3, randomized, double-blind, multicenter study investigated the efficacy and safety of mFOLFOX6 with/without ADX in pts with untreated HER2-negative gastric or GEJ adenocarcinoma. Randomization was 1:1 to mFOLFOX6 + ADX or mFOLFOX6 + placebo (PBO). Oxaliplatin was administered on Days 1 and 15 of each 28-day treatment cycle (total of 6 cycles), followed by leucovorin and 5-fluorouracil dosing on Days 1 and 15 of each 28-day treatment cycle until disease progression. ADX/PBO 800 mg was infused on Days 1 and 15 of each 28-day cycle until disease progression. The study had 85% power (one-sided significance of 0.025) to detect a hazard ratio of 0.7 for overall survival (OS) by intention-to-treat analysis using the log-rank test. Secondary endpoints were PFS, objective response rate (ORR, RECIST 1.1), and safety. Results: Between September 2015 and May 2017, 432 pts were randomized; 218 pts to ADX and 214 pts to PBO. Median (95% CI) OS was 12.5 (11.2, 14.0) vs 11.8 (10.3, 13.5) months in the ADX and PBO groups, respectively (HR 0.93 [0.74, 1.18], two-sided p=0.56). Median PFS was 7.5 vs 7.1 months in the ADX and PBO groups, respectively (HR 0.84 [0.672, 1.038], two-sided p=0.10). Median investigator assessed ORR was 50.5% vs 41.1% in the ADX and PBO groups, respectively (two-sided p=0.049). The most common treatment-emergent adverse events were nausea, diarrhea, neutropenia, and fatigue. There were no meaningful differences in the safety profile of the ADX vs PBO groups. Subgroup analysis is ongoing. Conclusion: Additionof ADX to mFOLFOX6 does not improve OS in pts with untreated HER2-negative gastric or GEJ adenocarcinoma. Clinical trial information: NCT02545504.

LBA5 Background: VEGF and VEGF receptor-2 mediated signaling and angiogenesis may contribute to gastric cancer pathogenesis. Ramucirumab (RAM; IMC-1121B) is a fully human IgG1 monoclonal antibody targeting VEGF-receptor 2. We conducted a placebo-controlled, double-blind, phase III international trial to evaluate the safety and efficacy of RAM in pts with metastatic gastric or GEJ adenocarcinoma progressing on first-line platinum- and/or fluoropyrimidine containing combination therapy. Methods: Pts were randomized 2:1 to receive RAM (8 mg/kg IV) plus BSC or placebo (PL) plus BSC every 2 weeks (wks) until disease progression, unacceptable toxicity, or death. Eligible patients had disease progression within 4 months (m) after 1st-line therapy for metastatic disease or within 6 m after adjuvant therapy. The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), 12-wk PFS rate, overall response rate (ORR) and safety. Results: From 10/09 to 01/12, 355 pts were randomized (RAM: 238; PL: 117). Baseline characteristics were well balanced between arms. The Hazard Ratio (HR) for OS was 0.776 (95% CI, 0.603-0.998; p = 0.0473). Median OS was 5.2 m for RAM and 3.8 m for PL. The HR for PFS was 0.483 (95% CI, 0.376-0.620; p < 0.0001). Median PFS was 2.1 m for RAM and 1.3 m for PL. 12-wk PFS was 40% for RAM and 16% for PL. ORR was 3.4% for RAM and 2.6% for PL. Disease control rate was 49% for RAM and 23% for PL (p < 0.0001). Use of anti-cancer therapy post-study: 32% RAM; 39% PL. The most frequent of grade ≥ 3 adverse events (AEs) were: hypertension (7.2% RAM; 2.6% PL), anemia (6.4% RAM; 7.8% PL), abdominal pain (5.1% RAM; 2.6% PL), ascites (4.2% RAM; 4.3% PL), fatigue (4.2% RAM; 3.5% PL), decreased appetite (3.4% RAM; 3.5% PL) and hyponatremia (3.4% RAM; 0.9% PL). Conclusions: Ramucirumab conferred a statistically significant benefit in OS and PFS compared to PL in metastatic gastric or GEJ adenocarcinoma following progression on 1st-line therapy with an acceptable safety profile. Clinical trial information: NCT00917384.

LBA8006^ Background: RAM is a human IgG1 monoclonal antibody that targets the extracellular domain of VEGFR-2. The REVEL study evaluated the efficacy and safety of RAM+DOC vs. PL+DOC (DOC) in patients (pts) with stage IV nonsquamous (NSQ) and squamous (SQ) NSCLC after platinum-based therapy. Methods: Pts with NSQ and SQ stage IV NSCLC were randomized 1:1 (stratified by sex, region, ECOG PS, and prior maintenance therapy) to receive DOC 75 mg/m2 in combination with either RAM 10 mg/kg or PL on day 1 of a 21-day cycle until disease progression, unacceptable toxicity, or death. The primary endpoint was overall survival (OS). Secondary efficacy endpoints included progression-free survival (PFS), and objective response rate (ORR). Results: Between Dec 2010 and Feb 2013, 1,253 pts (26.2% SQ) were randomized (RAM+DOC: 628; DOC: 625). Pt characteristics were balanced between arms. ORR was 22.9% for RAM+DOC and 13.6% for DOC (P<0.001). The hazard ratio (HR) for PFS was 0.762 (P<0.0001); median PFS was 4.5 months (m) for RAM+DOC vs. 3.0m for DOC. REVEL met its primary endpoint; the OS HR was 0.857 (95% CI 0.751, 0.98; P=0.0235); median OS was 10.5m for RAM+DOC vs. 9.1m for DOC. OS was longer for RAM+DOC in most pt subgroups, including SQ and NSQ histology. Grade ≥3 adverse events (AEs) occurring in >5% of pts on RAM+DOC were neutropenia (34.9% vs. 28.0%), febrile neutropenia (15.9% vs. 10.0%), fatigue (11.3% vs. 8.1%), leukopenia (8.5% vs. 7.6%), hypertension (5.4% vs. 1.9%), and pneumonia (5.1% vs. 5.8%). Grade 5 AEs were comparable between arms (5.4% vs. 5.8%), as was pulmonary hemorrhage (any grade; all pts: 2.1% vs. 1.6%; SQ pts: 3.8% vs. 2.4%). Conclusions: REVEL demonstrated a statistically significant improvement in ORR, PFS, and OS for RAM+DOC vs DOC in NSCLC pts with stage IV NSCLC as second-line treatment after platinum-based therapy. Benefits were similar in NSQ and SQ pts, and no unexpected AEs were identified. Clinical trial information: NCT01168973.

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 .

TPS6589 Background: The PD-1 inhibitor pembrolizumab is currently approved as first-line monotherapy for patients with R/M HNSCC whose tumors express PD-L1 combined positive score (CPS) ≥1. In a phase 1b/2 trial (NCT02501096) of pembrolizumab plus lenvatinib (multikinase inhibitor of VEGFR 1-3, FGFR 1-4, PDGFRa, RET, and KIT) in solid tumors, the combination demonstrated promising antitumor activity and a manageable safety profile in patients with HNSCC. LEAP-010 (NCT04199104) is a randomized, double-blind, placebo-controlled, phase 3 study that will evaluate the efficacy and safety of first-line pembrolizumab with or without lenvatinib in patients with PD-L1–positive R/M HNSCC. Methods: Key eligibility criteria include histologically confirmed R/M HNSCC incurable by local therapies, PD-L1–positive tumor (CPS ≥1) as determined by central laboratory, measurable disease as assessed by blinded independent central review (BICR) per RECIST v1.1, and ECOG performance status (PS) 0 or 1. Patients will be randomly assigned 1:1 to pembrolizumab plus lenvatinib or pembrolizumab plus placebo. Randomization will be stratified by PD-L1 status defined by tumor proportion score ( < 50% vs ≥50%), human papillomavirus status for oropharynx cancer (positive vs negative), and ECOG PS (0 or 1). Patients will receive intravenous pembrolizumab 200 mg every 3 weeks for 35 cycles (~2 years) and oral lenvatinib 20 mg or placebo once daily; patients may continue to receive lenvatinib or placebo after pembrolizumab treatment is complete. Treatment will continue until BICR-verified disease progression or unacceptable toxicity. Pembrolizumab retreatment (second course) for 17 additional cycles will be allowed for eligible patients who stop pembrolizumab and subsequently experience BICR-verified disease progression. These patients could have stopped treatment with stable disease, partial response, or complete response or after 35 cycles of pembrolizumab for reasons other than disease progression or toxicity. Tumor imaging assessment will be performed at week 6, then every 6 weeks until 1 year, and thereafter every 9 weeks. Primary end points are objective response rate and progression-free survival, assessed by BICR per RECIST v1.1, and overall survival. Secondary end points are duration of response and safety and tolerability. Recruitment is ongoing; planned enrollment is ~500 patients. Clinical trial information: NCT04199104 .

Current guidelines recommend two-drug cytotoxic chemotherapy with a fluoropyrimidine (fluorouracil or capecitabine) and a platinum-based agent (oxaliplatin or cisplatin) as first-line treatment for advanced gastric cancer. Pembrolizumab monotherapy has demonstrated durable antitumor activity in patients with advanced programmed death ligand 1-positive (combined positive score ≥1) gastric/gastroesophageal junction adenocarcinoma. Accumulating evidence indicates that combining pembrolizumab with standard-of-care chemotherapy for the treatment of advanced or metastatic cancer improves clinical outcomes. We describe the rationale for and the design of the randomized, double-blind, placebo-controlled, Phase III KEYNOTE-859 study, which is investigating pembrolizumab in combination with chemotherapy as first-line treatment for patients with human epidermal growth factor receptor 2-negative advanced unresectable or metastatic gastric/gastroesophageal junction adenocarcinoma. The planned sample size is 1542 patients, and the primary end point is overall survival. Clinical trial registration: NCT03675737 (ClinicalTrials.gov)

512 Background: Angiogenesis is an important therapeutic target in CRC; VEGF plays a key role in angiogenesis. RAM is a human IgG1 monoclonal antibody that targets the extracellular domain of VEGFR-2. The RAISE study evaluated the efficacy and safety of adding RAM to standard second-line treatment FOLFIRI. Methods: Eligible pts with mCRC who progressed on or after first-line combination therapy with bev, ox, and fp, had an ECOG PS of 0 or 1, and adequate organ function were randomized 1:1 (stratified by region, KRAS mutation status, and time to progressive disease [PD] after beginning first-line treatment) to receive RAM (8 mg/kg IV) plus FOLFIRI or PBO plus FOLFIRI every 2 weeks until PD, unacceptable toxicity, or death. The primary endpoint was overall survival (OS). Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), and safety. Planned sample size of 1,050 pts ensured 85% power to demonstrate statistical significance at an overall two-sided alpha of 0.05, assuming a hazard ratio (HR) of 0.8. Results: Between Dec 2010 and Aug 2013, 1,072 eligible pts were randomized (RAM 536; PBO 536). Baseline pt characteristics were similar between treatment arms. The OS HR was 0.84 (95% CI: 0.73, 0.98; log-rank p=0.0219). Median OS was 13.3months (m) for RAM vs 11.7m for PBO. The PFS HR was 0.79 (95% CI: 0.70, 0.90; log-rank p = 0.0005). Median PFS with RAM was 5.7m and 4.5m for PBO. ORR was 13.4% RAM; 12.5% PBO (p = 0.6336). Subgroup results were consistent with the OS and PFS results. Grade ≥3 adverse events (AEs) occurring in >5% of pts in RAM+FOLFIRI were: neutropenia (RAM 38.4% vs PBO 23.3% ), hypertension (11.2% vs 2.8%), diarrhea (10.8% vs 9.7%), and fatigue (11.5% vs 7.8%). Conclusions: RAISE met its primary end-point, demonstrating a statistically significant improvement in OS for RAM and FOLFIRI vs PBO and FOLFIRI in second-line mCRC pts. Benefits were similar across important clinical subgroups and no unexpected AEs were identified. Clinical trial information: NCT01183780.
