103 Background: The clinical benefit and safety profile of apatinib in advanced gastric cancer have been established in the randomised controlled phase III clinical trial (J Clin Oncol. 34(13):1448-54). A post-marketing study to confirm the safety and efficacy of apatinib is ongoing in a broad range of patients (pts). Methods: This is a single-arm, open-label, multi-center, Phase IV trial with the target sample size of 2000+ (ClinicalTrials.gov Identifier: NCT02426034). Pts were recruited to receive oral apatinib until disease progression, death or unacceptable toxicity. The primary objective was safety, and the secondary objectives included overall response rate (ORR), disease control rate (DCR), progression free survival (PFS) and overall survival (OS). Results: Herein, we report the preliminary data as documented in the EDC System. As of Jul 10, 2017, 1037 pts were enrolled from 138 hospitals across China. Pts characteristics were: median age 59 yrs, male/female 72.0/28.0%, ECOG PS 0/1/≥2 16.6/66.2/17.2%, stage IV 91.0%. 336 (32.4%) pts interrupted treatment and dose modification occurred in 172 (16.6%) pts (reduction 132/12.7%; rise 87/8.4%). Eventually, the mean dosage was 526.2 mg/d. 652 (62.9%) pts had 4407 drug-related adverse events (DRAEs). Grade ≥3 DRAEs occurred in 300 (28.9%) pts. Severe AEs were reported by 221 (21.3%) pts. The most common DRAEs were proteinuria (19.3%), hypertension (18.8%), leukocyte decrease (16.4%), fatigue (14.2%), platelet decrease (13.6%), hand-foot-skin reaction (11.1%) and neutrophil decrease (10.1%). 820 pts were evaluable for efficacy analysis. The best ORR and DCR were 10.7% and 70.0%, respectively. The median PFS and OS were 4.60 (95%CI, 3.25–4.73) and 6.57 (95%CI, 5.78–7.59) months, respectively. Conclusions: Apatinib monotherapy is effective and has a favorable toxicity profile in real-world clinical setting. The preliminary results of this Phase IV study confirmed the safety and efficacy of apatinib demonstrated in the Phase II and III trials. Updated results will be discussed. Clinical trial information: NCT02426034.

LBA8003 Background: PemC and PCB are regimens used for first-line treatment of advanced NS-NSCLC. The primary objective was to compare progression-free survival without Grade 4 toxicity (G4PFS) between two vs three drug regimen arms. Methods: Patients ≥18 years, Stage IV NS NSCLC, AJCC (v7.0), and ECOG PS 0/1 were enrolled. Patients were randomized (1:1); received 4 cycles of induction (PemC: Pem, 500 mg/m2 and C, AUC = 6; PCB: P, 200 mg/m2, C, AUC = 6, and B, 15 mg/kg) followed by Pem (PemC Arm) or B (PCB Arm) maintenance therapy in the absence of progressive disease or discontinuation. Secondary endpoints were PFS, overall survival (OS), overall response rate (ORR), and disease control rate (DCR). The study was powered for G4PFS; assuming hazard ratio (HR) of 0.75; there was 80% power to detect superiority of PemC over PCB with a 2-sided type I error of 0.10. Efficacy data were analyzed by intent-to-treat principle using the log-rank test for time-to-event variables, and an exact test for ORR and DCR. Safety data were evaluated using CTCAE v3 for patients who received ≥1 dose of study treatment. Results: Patients were randomized to PemC (N = 182) or PCB (N = 179). Baseline factors were balanced between arms: median age 66/66 years; % female 42/42; % PS=0, 47/47; % stage IV M1a 29/30; for PemC vs PCB, median G4PFS (months) was 3.91/2.86 (HR = 0.85, 90% CI 0.7, 1.04, p = 0.176); PFS and OS had HR = 1.06 (95% CI 0.84, 1.35), p = 0.610, and HR = 1.07 (95% CI 0.83, 1.36), p = 0.616, respectively. The ORR (%) 23.6/ 27.4 and DCR (%) 59.9/57.0 were for PemC vs PCB, respectively. Significantly more drug-related grade 3/4 anemia (18.7% vs 5.4%), and thrombocytopenia (24.0% vs 9.6%) were seen on PemC; significantly more grade 3/4 neutropenia (48.8% vs 24.6%) and grade 1/2 alopecia (28.3 % vs 8.2%) were seen on PCB. Conclusions: PemC was not superior to PCB in G4PFS; no difference in PFS or OS was observed for the two- vs three-drug regimens. There were no unexpected toxicities; the toxicity profiles demonstrated distinctions by arm, and both regimens demonstrated tolerability. Clinical trial information: NCT00948675.

40 Background: The single-arm, open-label, multi-center, Phase IV trial of apatinib was conducting in patients (pts) with advanced or metastatic adenocarcinoma of stomach or gastroesophageal junction with a target sample size of 2000+. We aimed to analyze the effect of region and hospital attributes on clinical outcomes. Methods: From April 2015 to July 2017, 1037 subjects were enrolled, among which 820 were evaluable in the survival analysis. Results: The incidences of adverse events (AEs) and severe AEs (SAEs) are listed in Table. Overall, both incidences were higher in Southern center compared to Northern Center (p=0.002 and <0.001). More SAEs occurred in developed cities (p=0.028) and in hospitals not specialized in oncology (p=0.028). For efficacy, the median overall survival (mOS) of subjects in Northern Center and Southern centers were 8.71 and 5.72 mos (p<0.001), and the median progression free survival (mPFS) was 5.36 and 3.25 mos (p=0.002), respectively. The mOS of subjects in developed and developing cities were 6.18 and 5.72 mos (p=0.105), and the mPFS was 3.02 and 4.73 mos (p=0.013), respectively. The mOS of subjects in hospital specialized and those not in oncology were 7.59 and 5.78 mos (p=0.014), and the mPFS was 4.73 and 3.84 mos (p=0.068), respectively. Conclusions: Region and attribute hospital can affect the safety and clinical outcome of apatinib in treating gastric cancer in the real world. Patients Northern, developing city or hospitals specialized in oncology experience less SAEs but have better clinical benefit. Clinical trial information: NCT02426034. [Table: see text]

7545 Background: Obinutuzumab (G)-chemotherapy (chemo) has demonstrated improved progression-free survival compared with rituximab (R)-chemo in previously untreated advanced follicular lymphoma (FL). G is currently administered by IV infusion over ̃3–4 hours. A shorter duration of infusion in Cycle (C) 2 and subsequent cycles, as is standard practice with R, could improve convenience for patients (pts) and efficiency for infusion facilities. We report the primary analysis of the prospective, open-label, multicenter, single-arm, Phase IV, GAZELLE study (NCT03817853), which evaluated the safety of G administered as a 90-minute (min) SDI from C2 onwards in pts with FL. Methods: Pts with previously untreated FL received G (1000mg) intravenously on Day (D) 1, 8, and 15 of C1, and on D1 thereafter, plus chemo (bendamustine, CHOP, or CVP) for 6–8 cycles. In C1, pts received G at the standard infusion rate. Pts without a Grade (Gr) ≥3 infusion-related reaction (IRR) in C1 were eligible to receive G as a 90-min SDI from C2. Pts with a Gr 3 IRR in C1 received the standard G infusion in C2, and were eligible for G SDI in subsequent cycles if no Gr ≥3 IRRs occurred. Pts with a second Gr 3/4 IRR discontinued G. At the end of induction (EOI), responding pts received maintenance G (1000mg) as SDI for 2 years or until disease progression (PD). The primary endpoint was incidence of Gr ≥3 IRRs during C2. IRRs were defined as any event occurring ≤24 hours from infusion judged to be related to treatment. Secondary endpoints included adverse events (AEs) and investigator-assessed overall response rate at EOI. Results: As of December 3, 2020, 113 pts had received study treatment. Median age was 62.0 years, 50.4% were male, 61.9% had stage IV FL, and 45.1% were classified as high-risk FLIPI. Of the 110 pts who were eligible for G SDI from C2, no pt experienced a Gr ≥3 IRR with SDI in C2 (Table). One pt experienced a Gr 3 IRR with SDI in C5, presenting hypertension. All other IRRs with SDI were Gr 1/2. No Gr 4/5 IRRs were reported. Other AEs were similar to those observed in previous studies. At the clinical cut-off date, 104 pts had a CT imaging-based response assessment at EOI and 9 pts had no response assessment; 76/113 (67.3%) had a complete response, 22 (19.5%) had a partial response, and six (5.8%) had PD. Conclusions: In GAZELLE, G SDI in C2 and beyond appeared to be safe. No Gr 3 IRRs were observed in C2 and only one Gr 3 IRR was reported in subsequent cycles. The safety profile of G SDI was comparable with the established profile of G in advanced FL. Clinical trial information: NCT03817853. [Table: see text]

9029 Objectives: Evaluate the safety and efficacy of CNTO 95, a human anti-αv integrin monoclonal antibody, when administered alone or in combination with dacarbazine (DTIC). Methods: Patients with Stage IV metastatic melanoma were randomized 1:1:1:1 to receive 5 or 10mg/kg CNTO 95 alone, or DTIC (1000mg/m2) + either 10mg/kg CNTO 95 or placebo administered intravenously once every 3 weeks for 8 cycles in the absence of disease progression or unacceptable toxicity. DTIC arms were blinded; single-agent arms were open-label. The primary endpoint was progression free survival (PFS); secondary endpoints included partial response (PR), complete response (CR), stable disease (SD) and overall survival (OS). Major safety endpoints included the incidence of adverse events (AEs) and serious AEs (SAEs). Results: Patients were randomized to receive 5mg/kg CNTO 95 (n=32), 10mg/kg CNTO 95 (n=33), CNTO 95+DTIC (n=32), or placebo+DTIC (n=32). Baseline demographics were similar across groups. The median PFS for CNTO 95+DTIC was 75 days, placebo+DTIC was 54 days and both CNTO 95 alone arms were 42 days. Six patients achieved PR (2–10mg/kg CNTO 95, 1-CNTO 95+DTIC, 3-placebo+DTIC); one patient achieved CR (CNTO 95+DTIC). A higher proportion (43.3%) of patients achieved SD ≥ 12 wks in the CNTO 95+DTIC group compared with the other 3 groups (<20.0%). The median survival was 11.0 months for the patients in the CNTO 95+DTIC arm, 9.8 months and 14.9 months for the 5mg/kg and 10mg/kg arms, and 8.0 months for those in the DTIC control arm. The most common AEs were headache, nausea, fatigue, pyrexia, vomiting and transient uveitic reactions. Three patients (1–5mg/kg, 2-CNTO 95+DTIC) discontinued treatment due to AEs. A higher proportion of patients experienced SAEs in the placebo+DTIC group (29.0%) than in the 5mg/kg (12.9%), 10mg/kg (16.2%) or CNTO 95+DTIC (18.8%) groups. Conclusions: CNTO 95 alone or combined with DTIC was generally well tolerated. In patients with Stage IV metastatic melanoma, a trend toward improvement in PFS, OS and disease control was demonstrated with CNTO 95+DTIC. Centocor, Centocor Research and Development, Inc.

7502 Background: SELECT investigated whether the addition of C to standard chemotherapy improved progression-free survival (PFS) in patients (pts) with recurrent or progressive NSCLC after failure of platinum-based therapy. Methods: SELECT was a multicenter, open label, randomized phase III trial. Per investigator choice, pts received either P (500 mg/m2) or D (75 mg/m2) on day 1 and then were randomized within each group to chemotherapy plus C (400/250 mg/m2) (initial/weekly) or chemotherapy alone. Therapy was given for up to six 3-week cycles; pts randomized to C continued weekly monotherapy until disease progression or unacceptable toxicity. The primary objective was PFS for PC vs. P as determined by an Independent Review Committee (IRC). Secondary endpoints included overall survival (OS), objective response rate (ORR) and duration of response (DOR) by IRC, and safety. Preplanned subgroup analyses for epidermal growth factor receptor (EGFR) staining intensity by immunohistochemistry and histology were performed. Results for PC vs. P only are presented. Results: Between Jan 2005 and Feb 2010, 938 total pts were randomized. Baseline demographics were comparable between PC (n=301) and P (n=304): median age 64 years; male 60%; Caucasian 88%; KPS 80-100/60-70 84%/16%; squamous/non-squamous 24%/76%. Median PFS (months) PC: 2.89 and P: 2.76 (hazard ratio [HR] =1.03 [95% confidence interval (CI)=0.87-1.21]; p=0.76). Median OS (months) PC: 6.93 and P: 7.79 (HR=1.01 [95% CI=0.86-1.20]; p=0.86). ORR PC: 6.6% and P: 4.3% (odds ratio =1.59 [95% CI=0.78-3.26]; p=0.20). Median DOR (months) PC: 4.17 and P: 6.93 (HR=1.58 [95% CI=0.74-3.36]; p=0.24). There were no statistical differences in efficacy based on histology or EGFR staining intensity. More drug-related AEs/SAEs were observed in the PC arm, with differences mainly attributable to skin toxicities, GI (diarrhea/stomatitis), and hypomagnesemia. Conclusions: The addition of C to P did not improve efficacy in this pt population. Further biomarker analyses are planned. The safety profiles for C and P were consistent with existing data and no new safety signals were observed.

6028 Background: Cisplatin plus fluorouracil (PF) is main therapy for metastatic nasopharyngeal carcinoma (NPC). However, the efficacy is not satisfactory, especially in patients with metastasis after radical radiotherapy. The purpose of this study was to investigate the efficacy and toxicity of Nimotuzumab combined with PF in patients with metastatic NPC after radical radiotherapy. Methods: Patients with untreated metastatic NPC after radical radiotherapy were recruited from 9 hospitals in China with Simon’s two-stage design. All patients received Nimotuzumab (200mg/w) and cisplatin (100mg/m2, day 1) plus fluorouracil (4g/m², day 1-4) every 3 weeks until progressive disease (PD) or unacceptable toxicity or a maximum of 6 cycles. If patients had still not progressed at this stage, Nimotuzumab (200mg/w) as monotherapy would be delivered until PD. This study was registered in ClinicalTrials.gov, Number NCT01616849. Results: Between Jun, 2012 and April, 2015, 35 patients were enrolled (Table). The objective response rate (ORR) and disease control rate (DCR) were 71.4% and 85.7%, and the median time of progression free survival (PFS) and overall survival (OS) were 6.97 and 11.01 months. The most common toxicities were leukopenia (94.1%), vomiting (97.1%) and nausea (97.1%); the grade 3/4 toxicities were leukopenia (62.9%) and mucositis (20.0%). There was only 1 patient have mild hypotension which related to Nimotuzumab. The ORR, DCR, median time of PFS and OS were 88.9%, 100.0%, 7.29 and 11.47 months in patients who received a total dose of Nimotuzumab ≥ 2400mg, respectively. Conclusions: Nimotuzumab combined with PF has achieved encouraging efficacy with an acceptable safety profile in metastatic NPC after radical radiotherapy. A phase III randomised study is needed. Clinical trial information: NCT01616849. [Table: see text]

TPS539 Background: Bleomycin, etoposide, cisplatin (BEP) given 3-weekly x 4 remains standard 1st line chemotherapy for metastatic GCTs. Acceleration of standard regimen with shorter cycle lengths has improved cure rates in other cancers. This is the first international randomised clinical trial for intermediate and poor-risk metastatic extracranial GCTs involving both adult and paediatric age group males and females. We aim to determine if accelerated BEP is superior to standard BEP. Methods: DESIGN: Open label, randomised, stratified multicentre, 2 stage, phase 3 trial. Primary endpoint for stage I (n = 150) is the achievement of a complete response (CR), and for entire trial (n = 500) is progression free survival (PFS). SAMPLE SIZE: 150 and 500 patients gives > 80% power to detect a 20% improvement in achieving a CR and 7% absolute improvement in 2yr PFS, respectively. POPULATION: Males and females aged 11-45 years with intermediate or poor-risk metastatic GCTs of the testis, ovary, retroperitoneum or mediastinum for 1st line chemotherapy. TREATMENT: Randomisation 1:1 to 4 cycles of “standard BEP” or “accelerated BEP”: cisplatin 20mg/m2 IV D1-5; etoposide 100mg/m2 IV D1-5; bleomycin 30000 IU IV weekly; and pegylated G-CSF SC D6 or Filgrastim daily; given every 3 weeks or every 2 weeks respectively. Accelerated BEP arm receives 4 additional weekly doses of bleomycin. ASSESSMENTS: Response assessments at 30 day safety assessment, and 6 months from randomisation or after all post-chemotherapy intervention is completed. Regular follow-up up to 5 years, then annually. Archival tumour tissue and baseline blood collected for translational substudies. STATUS: 25 sites open in ANZ, 11 sites open in UK (led by Cambridge Clinical Trials Unit), 19 sites open in the USA (led by Children’s Oncology Group). As of 23rd October 2018, 59 patients have been recruited. Clinical trial information: NCT02582697.

278 Background: We report the primary analysis of JAVELIN Gastric 100, which compared avelumab (anti–PD-L1) maintenance after 1L CTx vs continued CTx in patients (pts) with GC/GEJC. Methods: In this global, open-label, phase 3 trial (NCT02625610), eligible pts had previously untreated, unresectable, locally advanced/metastatic (LA/M) HER2− GC/GEJC. Pts without progressive disease (PD) after 12 weeks of 1L oxaliplatin/fluoropyrimidine induction were randomized 1:1 to avelumab 10 mg/kg Q2W switch maintenance or continued CTx, stratified by region (Asia vs non-Asia). Primary endpoint was overall survival (OS) post induction in all randomized or PD-L1+ (≥1% of tumor cells, 73-10 assay) pts. Results: 805 pts received induction CTx and 499 pts were randomized (avelumab, n = 249; CTx, n = 250). At data cutoff (Sep 13, 2019), minimum follow-up was 18 months. In the avelumab and CTx arms, median OS post induction/randomization was 10.4 months (95% CI 9.1-12.0) vs 10.9 months (95% CI 9.6-12.4), hazard ratio (HR) 0.91 (95% CI 0.74-1.11; p = 0.1779); 24-month OS rates were 22.1% (95% CI 16.8-28.0) vs 15.5% (95% CI 10.8-20.9), respectively. The HR for OS in PD-L1+ pts (n = 54) was 1.13 (95% CI 0.57-2.23). No OS trend was seen in Asian pts (n = 114; HR 0.90 [95% CI 0.59-1.36]) or other subgroups, except for a potential benefit with avelumab in pts with no metastatic sites at randomization (n = 60; HR 0.52 [95% CI 0.28-0.98]). Progression-free survival was similar between arms (HR 1.04 [95% CI 0.85-1.28]). In the avelumab vs CTx arms, objective response rates (post randomization only) were 13.3% (95% CI 9.3-18.1) vs 14.4% (95% CI 10.3-19.4), and 12-month rates for duration of response were 62.3% (95% CI 40.9-77.9) vs 28.4% (95% CI 13.2-45.7), respectively. Treatment-related adverse event rates (all grades/grade ≥3) were 61.3%/12.8% with avelumab and 77.3%/32.8% with CTx. Conclusions: Avelumab maintenance showed clinical activity and favorable safety vs continued CTx in pts with LA/M GE/GEJC; however, JAVELIN Gastric 100 did not meet its primary objective of demonstrating superior OS in the randomized or PD-L1+ population. Clinical trial information: NCT02625610.

142 Background: Apatinib, a small molecule VEGFR TKI, has been approved in the treatment of advanced gastric cancer in China. Due to toxicity, many pts underwent temporary interruptions during treatment. We analyzed the data from a phase IV clinical trial of Ahead-G201 to evaluate the relationship between dose interruption, drug safety and efficacy. Methods: At the cutoff date of Jul 10, 2017, Ahead-G201 study enrolled 1037 pts. The adverse events (AEs) and clinical efficacy were evaluated for pts with no, 1, 2 and ≥3 dose interruptions. Results: 336 of 1037 pts underwent dose interruptions during apatinib treatment: 1 interruption in 183 pts; 2 interruptions in 67 pts; and ≥3 interruptions in 86 pts. The toxicity and efficacy for them were listed in Table. For safety, pts with no interruption had the lowest incidence of all AEs (59.3%) and grade 3-4 AEs (30.0%). Pts with ≥3 interruptions had the highest objective response rate (ORR, 20.3%) and disease control rate (DCR, 82.6%). Moreover, these pts got median progression-free survival (mPFS) of 6.6 mos and median overall survival (mOS) of 9.4 mos, which were the longest among 4 groups. Furthermore, multivariate analysis revealed that ≥3 interruptions of apatinib bring much more efficacy benefit both in mPFS (6.6 vs 3.8 mos: hazard ratio, 0.5, 95%CI, 0.3 to 0.7) and mOS (9.4 vs 6.6 mos: hazard ratio, 0.5, 95%CI, 0.3 to 0.8) for pts, than those with no interruption. Conclusions: Current results indicated that dose interruptions are required to manage toxicity and it is necessary to explore an optimal dosing pattern of apatinib in advanced gastric cancer. Clinical trial information: NCT02426034. [Table: see text]

Phase III randomized sequential open-label study to evaluate the efficacy of FOLFOX + panitumumab followed by FOLFIRI + bevacizumab (Sequence 1) versus FOLFOX+ bevacizumab followed by FOLFIRI + panitumumab (Sequence 2) in untreated patients with wild-type RAS metastatic, primary left (L)-sided, unresectable colorectal cancer (CRC): The CR-SEQUENCE.

TPS3618 Background: Both anti-EGFR and anti-VEGF therapies have shown clinical benefit when they are added in first and second-line in L-sided CRC. The conflicting results in anti-VEGF vs. anti-EGFR studies (FIRE-3, PEAK and CALGB/SWOG 80405 studies) suggest that the sequence of targeted therapies added to FOLFOX or FOLFIRI regimens in first- and second-line treatment could be an important factor in the overall survival (OS) of mCRC patients. Currently, there are no randomized data on the sequential use of an anti-EGFR followed by an anti-VEGF or vice versa. Therefore, the aim of this randomized clinical trial is to compare the efficacy of two treatment sequences, panitumumab followed by bevacizumab versus bevacizumab followed by panitumumab in combination with FOLFOX chemotherapy in first-line and with FOLFIRI in second-line in patients with wild-type RAS, primary L-sided, metastatic colorectal cancer (mCRC). Methods: A phase III, multicentre, open-label and randomized two-arm clinical trial. Untreated patients with wild-type RAS mCRC (determined locally), primary L-sided and unresectable will be screened for this trial. Eligible patients will be randomized 1:1 to receive first-line (1L) panitumumab plus FOLFOX and then bevacizumab plus FOLFIRI as second-line (2L) treatment (Seq. 1) or bevacizumab plus FOLFOX as 1L and then panitumumab plus FOLFIRI as 2L treatment (Seq. 2). Randomization will be stratified by number of metastatic organs involved (1 vs > 1). Primary objective is the comparison of the progression free survival (PFS) rate at 35 months (m) of Seq 1 vs Seq. 2. Secondary objectives: PFS from randomization to 2nd progression or death, OS rate at 35 months and OS of Seq. 1 vs Seq. 2; PFS, objective response rate, disease control rate, early tumour shrinkage, Depth of Response, duration and time to response and safety in 1L treatment and in 2L treatment in each Sequence arm. Exploratory objectives: impact of baseline biomarkers predictive of the efficacy in each Sequence arm and the clinical impact of clonal dynamics by longitudinal analysis of circulating tumour deoxyribonucleic acid (ctDNA) in plasma. The trial is in progress; 28 of up to 370 planned patients have been recruited at the end of January 2019 (first patient in 31 October 2018). Clinical trial information: NCT03635021.
