454 Background: Pmab has demonstrated significant improvement in progression-free survival (PFS) in pts with WT KRAS mCRC as 2nd-line tx in a phase III trial comparing pmab + FOLFIRI vs FOLFIRI alone. Here, we describe the results of SPIRITT, a multicenter, randomized phase II study evaluating pmab + FOLFIRI and bev + FOLFIRI in pts with WT KRAS mCRC previously treated with a 1st-line bev + oxaliplatin (Ox)-based chemotherapy regimen. Methods: Pts were randomized 1:1 to pmab 6.0 mg/kg + FOLFIRI Q2W or to bev 5.0 or 10.0 mg/kg + FOLFIRI Q2W. Eligibility criteria included: WT KRAS mCRC, ECOG ≤ 1, no prior irinotecan or anti-EGFR tx, and tx failure of prior 1st-line bev + Ox-based therapy (≥ 4 cycles). The primary endpoint was PFS; secondary endpoints included overall survival (OS), objective response rate (ORR), and safety. No formal hypothesis was tested. Results: 182 pts with WT KRAS mCRC were randomized. All pts received tx. Efficacy results are shown (table). Worst grade of 3/4 adverse events (AE) occurred in 78% of pts in the pmab + FOLFIRI arm and 65% in the bev + FOLFIRI arm. Grade 5 AEs occurred in 7% of pts in the pmab + FOLFIRI arm and 7% in the bev + FOLFIRI arm. Tx discontinuation due to any AE was 29% in the pmab + FOLFIRI arm and 25% in the bev + FOLFIRI arm. Conclusions: In this estimation study of pts with WT KRAS mCRC that previously received bev + Ox-based tx, the PFS hazard ratio (HR) was 1.01 (95% CI: 0.68 - 1.50). The OS HR was 1.06 (95% CI: 0.75 - 1.49). The observed ORR was higher in the pmab + FOLFIRI arm. 54% of bev + FOLFIRI pts received subsequent anti-EGFR tx. The safety profile for both arms was similar to previously reported studies. Tx discontinuation rates due to AEs were similar between the arms. Clinical trial information: NCT00418938.

446 Background: Pmab has demonstrated significant improvement in progression-free survival (PFS) in pts with WT KRAS mCRC as 1st-line tx in a phase III trial comparing pmab + FOLFOX4 vs FOLFOX4 alone. Here, we describe the results of PEAK, a multicenter, randomized phase II study evaluating pmab + mFOLFOX6 and bev + mFOLFOX6 in pts with previously untreated WT KRASmCRC. Methods: Pts were randomized 1:1 to pmab 6.0 mg/kg + mFOLFOX6 Q2W or bev 5.0 mg/kg + mFOLFOX6 Q2W. Pt eligibility criteria included: WT KRASmCRC, ECOG performance status ≤ 1, and no prior chemotherapy, anti-VEGF tx, or anti-EGFR tx for mCRC. The primary endpoint was PFS; secondary endpoints included overall survival (OS), objective response rate (ORR), and safety. No formal hypothesis was tested. Results: 285 pts with WT KRASmCRC were randomized and 278 pts received tx. Demographics were balanced between arms. Intent-to-treat efficacy results are shown (Table). Worst grade 3/4 adverse events (AE) occurred in 86% of pts in the pmab + mFOLFOX6 arm vs 76% of pts in the bev + mFOLFOX6 arm. Grade 5 AEs occurred in 5% of pts in the pmab + mFOLFOX6 arm and 6% of pts in the bev + mFOLFOX6 arm. Tx discontinuation due to any AE was 24% in the pmab + mFOLFOX6 arm and 27% in the bev + mFOLFOX6 arm. Conclusions: In this estimation study of pts with WT KRASmCRC without any prior therapy for mCRC, PFS and ORR were similar between arms. The median OS was not reached in the pmab + mFOLFOX6 arm. The safety profile for both arms was consistent with previously reported studies of either combination. Tx discontinuation rates due to AEs were similar between arms.

4082 Background: Tivantinib is a selective, non-ATP competitive, small-molecule inhibitor of c-MET and is under development in several cancers such as NSCLC and HCC. Elevated expressions of c-MET and its ligand, hepatocyte growth factor, have been frequently found in gastric cancer, and are associated with a more aggressive phenotype. In this single-arm phase II study, we evaluated the efficacy of tivantinib monotherapy in Asian patients (pts) with previously treated metastatic gastric cancer (MGC). This is the first clinical trial evaluating the efficacy of a selective c-MET inhibitor for MGC. Methods: Eligibility criteria included MGC with at least 1 measurable lesion per RECIST; 1 or 2 prior chemotherapy regimens; ECOG PS 0 or 1; and normal CYP2C19 metabolism. Tivantinib was daily administered 360 mg bid orally. The primary endpoint was disease control rate (DCR) defined as CR, PR or SD after 8 weeks administration. Pretreatment tumor tissue collection was required to evaluate the relationship between biomarkers and efficacy. Pharmacokinetic (PK) evaluation was also conducted. Results: Thirty patients received tivantinib and were eligible for analysis: median age 62.5 (41-70) years; ECOG PS 0/1 (8/22); 1/2 prior regimen (16/14); 12 pts (40%) with prior gastrectomy. No objective response was observed, and DCR was 36.7% (11/30 pts). Median progression-free survival was 43 (95% CI: 29.0-92.0) days. Grade 3 or 4 adverse events (AEs) occurred in 13 pts (43.3%), in which neutropenia (n = 4) and anemia (n = 4) were recognized as drug-related. Only 2 pts discontinued due to AEs. There is no treatment-related death and novel safety concern. c-MET gene amplification (≥ 5 copies/cell) was observed in 4 pts (13.3%). No obvious relationship of treatment outcome with biomarkers including c-MET gene amplification, c-MET, p-c-MET and HGF expression in tumor and serum HGF was identified. Gastrectomy and/or ethnicity (Korean or Japanese) did not affect PK parameters. Conclusions: Tivantinib as a monotherapy showed only a modest efficacy in previously treated MGC, and further trial testing in combination would be warranted in MGC. It would be an important finding that gastrectomy do not affect PK profile of tivantinib.

8009 Background: Vandetanib is a once-daily oral inhibitor of VEGFR, EGFR and RET signaling. This phase III study compared the efficacy of vandetanib vs erlotinib in patients (pts) with advanced, previously treated NSCLC. Methods: Eligible pts (stage IIIB/IV NSCLC, PS 0–2, 1–2 prior chemotherapies; all histologies permitted) were randomized 1:1 to receive vandetanib 300 mg/day or erlotinib 150 mg/day until progression/toxicity. The primary objective was to show superiority in progression-free survival (PFS) for vandetanib vs erlotinib. Secondary endpoints included overall survival (OS), objective response rate (ORR), time to deterioration of symptoms (TDS; EORTC QoL Questionnaire) and safety. Results: Between Oct 06-Nov 07, 1240 pts (mean age 61 yrs; 38% female; 22% squamous) were randomized to receive vandetanib (n=623) or erlotinib (n=617). Baseline characteristics were similar in both arms. Median duration of follow-up was 14 months, with 88% pts progressed and 67% dead. There was no difference in PFS for pts treated with vandetanib vs erlotinib (hazard ratio [HR] 0.98, 95.22% CI 0.87–1.10; P=0.721), and no difference in the secondary endpoints of OS (HR 1.01, 95.08% CI 0.89–1.16; P=0.830), ORR (both 12%) and TDS (pain: HR 0.92, P=0.289; dyspnea: HR 1.07, P=0.407; cough: HR 0.94, P=0.455). A preplanned non-inferiority analysis for PFS and OS demonstrated equivalent efficacy for vandetanib and erlotinib. The adverse events (AEs) observed for vandetanib were generally consistent with previous NSCLC studies with vandetanib 300 mg. There was a higher incidence of some AEs (any grade) with vandetanib vs erlotinib, including diarrhea (50% vs 38%) and hypertension (16% vs 2%); rash was more frequent with erlotinib (38% vs 28%). The overall incidence of CTCAE grade ≥3 AEs was also higher with vandetanib (50% vs 40%). The incidence of protocol-defined QTc prolongation in the vandetanib arm was 5%. Conclusions: The study did not meet its primary objective of demonstrating PFS prolongation with vandetanib vs erlotinib in pts with previously treated advanced NSCLC. However, vandetanib and erlotinib showed equivalent efficacy for PFS and OS in a preplanned non-inferiority analysis. [Table: see text]

9055 Background: LungMAP is a National Clinical Trials Network umbrella trial for previously-treated SqNSCLC. S1400D is a phase II biomarker-driven therapeutic sub-study evaluating the FGFR inhibitor AZD4547 in patients (pts) with FGFR positive chemo-refractory SqNSCLC. Methods: Eligible pts had tumor FGFR alteration and/or mutation by next generation sequencing (Foundation Medicine), measurable disease, Zubrod PS 0-2, progression after 1 line of systemic therapy, and adequate end organ function. Receipt of prior immunotherapy was allowed. Eligible pts received AZD4547 80 mg bid orally. Primary endpoint was overall response rate (ORR) by RECIST; secondary endpoints included progression-free survival (PFS) and duration of response (DoR). Originally designed as a randomized trial of AZD4547 versus docetaxel, it was redesigned to be a single arm AZD4547 trial with the emergence of immunotherapy as standard 2ndline therapy. Forty pts were required to rule out an ORR of < = 15% if the true ORR was > 35% (90% power, alpha 0.05). Results: 93 pts (13% of pts screened on S1400) were assigned to S1400D; 43 were enrolled with 28 receiving AZD4547. Pt characteristics: median age 66.3 y (49-88), female (n = 8, 29%), & Caucasian (n = 25; 89%). Biomarker profile: FGFR1 amplification (n = 38; 86%); FGFR3 S249C (n = 4; 9%); FGFR3 amplification (n = 3; 7%); and FGFR3 fusion (n = 2; 5%). Nine pts (26%) had more than one biomarker alteration. The study was closed at interim analysis for futility in October 2016. Treatment related Grade 3 AEs were seen in 5 pts (dyspnea, fatigue, hyponatremia, lung infection & retinopathy); 1 pt had Grade 4 sepsis. There were no Grade 5 AEs. Median follow up among alive pts was 4.3 months (mos). Of 25 response evaluable pts, one with FGFR3 S249C had unconfirmed PR (4%, 95% CI 1-20%) with DoR of 1.5 mos. Median PFS was 2.7 mos (95% CI 1.4 - 4.3 mos). Conclusions: This is the first Phase II trial to evaluate AZD4547 as a targeted approach in pts with previously treated FGFR-altered SqNSCLC. AZD4547 had an acceptable safety profile but minimal activity in this biomarker-enriched cohort. Evaluation of other targeted agents in LUNG-MAP is currently ongoing. Clinical trial information: NCT02965378.

9014 Background: Lung-MAP is a master protocol for patients (pts) with stage IV previously treated SqNSCLC. S1400I enrolled pts who were not eligible for a biomarker-matched sub-study. Methods: S1400I is phase III randomized trial for immunotherapy-naïve patients with ECOG 0-1 not selected by PD-L1 expression. Pts were assigned 1:1 to nivolumab and ipilimumab (N+I) vs nivolumab (N). N was given at 3 mg/kg q 2w, I was given at 1 mg/kg q 6w. The primary endpoint was overall survival (OS). Secondary endpoints: investigator-assessed progression-free survival (IA-PFS), response by RECIST 1.1, and toxicity. Results: From December 18, 2015 to April 23, 2018, 275 pts enrolled and 252 determined eligible (125 N+I and 127 N). The study was closed for futility at an interim analysis. Baseline characteristics were similar across arms. mOS was 10.0 m (8.0-12.8) and 11.0 m (8.2-13.5) for N+I and N. HR 0.97 (0.71-1.31), p 0.82. mPFS was 3.8 m (2.3-4.2) and 2.9 m (1.8-3.9) for N+I and N. HR 0.84 (0.64-1.09), p 0.19. Outcomes based on PD-L1 and TBM subsets are shown in table. Response rates were 18% (12-25%) and 17% (11-24%) for N+ I and N. Median follow up for patients still alive was 17.4 m. Grade ≥3 treatment-related AEs occurred in 48(39%) of pts on N+I vs 38(31%) on N. irAE reported in 39% of pts on N+I and 34% of patients on N. Drug-related AEs led to discontinuation in 25% and 16% of pts on N+I and N. There were 5 grade 5 AE in N+I arm and 1 in N arm. Conclusions: S1400I failed to show improvement in outcomes with N+I. Study was closed for futility at interim analysis. Toxicities were not different between two arms. Clinical trial information: 02785952. [Table: see text]

1056 Background: Oral chemotherapy (CT) is attractive for patients (pts) with MBC. The all-oral regimen of NVBo and X is active with good tolerability in MBC. We report efficacy and safety data from an international phase II study of NVBo plus X. Methods: Main eligibility criteria included: measurable HER2-negative, CT-naive MBC, relapse ≥6 months after completing (neo)adjuvant CT, Karnofsky PS ≥70%, age ≥18 years. Study treatment: 3-weekly cycles of NVBo 60 mg/m2 (cycle 1) or 80 mg/m2 (from cycle 2) d1 and d8, plus X 1,000 (750 if ≥ 65 years) mg/m2 twice-daily d1–14. Treatment was continued until progression or unacceptable toxicity. Results: 55 pts were enrolled: median age: 58.5 years (41% ≥65); prior (neo)adjuvant CT in 63%; type of CT: anthracycline 67%, anthracycline + taxane 18%, CMF 15%; visceral involvement in 78%; >2 metastatic sites in 46%. Median 6 cycles; median relative dose intensity: NVBo 88%, X 87%; NVBo dose escalated to 80 mg/m2 in 94% of pts. G3/4 NCI CTC v2 adverse events (n=54): neutropenia 44% of pts, vomiting 9%, febrile neutropenia 7%, stomatitis 7%, asthenia 7%, infection with G3/4 neutropenia 4%, nausea 4%, diarrhea 4%, hand-foot syndrome 4%, thrombosis/embolism 4%. Efficacy (n=48 evaluable pts): objective response rate (RECIST) 44% (95% CI [29–59]), CR 2%, PR 42%, SD 35%, PD 21%, disease control (CR+PR+SD ≥6 months) 56%. Median time to objective response was 2.9 months. Because of short follow-up, progression-free survival, overall survival and duration of response data are not yet available. Conclusion: The all-oral combination of NVBo and X is an effective and well-tolerated first-line therapy for MBC. Based on these results and the high convenience of oral CT, evaluation of this regimen vs i.v. combinations in a randomized trial is ongoing. [Table: see text]

7100 Background: Amrubicin is a novel anthracycline associated with high objective response rates (ORR) in patients (pts) with relapsed SCLC. Amrubicin improved the ORR and progression-free survival (PFS) in relapsed SCLC vs. topotecan, but not overall survival (OS) in a phase III study. Amrubicin with cisplatin/carboplatin for elderly Japanese pts was safe and active. We conducted a multicenter phase II study evaluating amrubicin and carboplatin in newly diagnosed ES-SCLC. Methods: Eligible pts had untreated ES-SCLC, measurable/evaluable disease (RECIST v. 1.1) and an ECOG PS <2. Pts received 4 cycles of amrubicin 30 mg/m2 on days 1-3 and carboplatin AUC=5 both IV day 1 every 21 days with restaging every 6 weeks. Pegfilgrastim 6 mg sq was administered on day 4 of each cycle. The primary endpoint was 1-year OS. Secondary endpoints included ORR, PFS, OS, and toxicity. Results: 78 pts were enrolled from 3/2010 to 7/2011. Baseline characteristics included: median age 65 yrs (range 45-84); 56% female. 64% completed 4 cycles of treatment. Eleven (14%) pts showed complete responses and 47 (60%) pts partial responses, for an ORR of 74% (95% confidence interval 65%-82%). Twelve (15%) pts had stable disease. Median PFS and OS were 5.3 and 9.5 months, respectively. The 1-year OS was 36%. Grade 3/4 myelosuppression was the most common toxicity (thrombocytopenia 44%, neutropenia 34%, febrile neutropenia 12%, anemia 26%), but was manageable. Severe non-hematologic toxicities (>5%) included hypokalemia 17%, fatigue 13%, dehydration 10%, hyponatremia 10%, pneumonia 9%, and nausea/vomiting 8%. 1 pt died from sepsis and another from aspiration pneumonia. Conclusions: First-line ES-SCLC treatment with amrubicin and carboplatin induced several complete responses and is considered highly active. Myelosuppression was managed effectively with growth factor support. These results are comparable to historical data with platinum-doublet chemotherapy. A larger randomized study would be required to best assess this regimen’s impact on survival.

6029 Background: PARTNER was a multicenter, randomized phase II estimation study evaluating 1stEline tx of R/M SCCHN with doc/cis ± pmab. Methods: Patients (pts) were randomized 1:1 to doc/cis with pmab (Arm 1) or doc/cis alone (Arm 2). Arm 1 received 9 mg/kg pmab on day 1 of each 21-day cycle, and all pts received 1stEline doc/cis both at 75 mg/m2 on day 1 for up to 6 cycles. In Arm 1, pts could receive pmab monotherapy upon completion of 6 cycles of doc/cis until disease progression (PD). In Arm 2, pts could receive pmab as 2ndEline monotherapy upon PD. The primary endpoint was progression-free survival (PFS); secondary endpoints included overall survival (OS), objective response rate (ORR), and safety. HPV status was determined using p16 INK IHC. No formal hypothesis was tested. Results: Baseline characteristics were balanced between arms. Of 103 pts, HPV status was evaluable in 66 (64%); 29% were HPV positive. Efficacy results are shown (Table). Worst grade 3/4 adverse events (AEs) were 73% in Arm 1 vs 56% in Arm 2. Conclusions: Median PFS was increased in both arms over historical doublet cytotoxic chemotherapy. PFS and ORR were higher in the pmab arm in the overall population, in the HPV positive (n=19) group, and in the HPV negative (n=47) group. There was an increase in grade 3/4 AEs with this regimen. The crossover design, with 57% of Arm 2 pts receiving pmab as 2ndEline monotherapy, confounds interpretation of OS. Clinical trial information: NCT00454779. [Table: see text]

106 Background: CUP has a poor prognosis with a median survival of less than 12 months. Given the recent approval of immune checkpoint inhibitors in several cancer types, we performed a multicenter phase II study of nivolumab in CUP patients (pts). Methods: The main population of this study is CUP pts who were previously treated with more than one line of systemic chemotherapy. Previously untreated CUP pts were also enrolled for exploratory analysis. Pathological examination (including IHC), CT, FDG-PET, gastroscopy and colonoscopy and medical examination were mandatory for diagnosis of CUP before enrollment. CUP pts belonging to favorable prognosis groups were excluded from the trial. Nivolumab (240 mg/body) was delivered as an intravenous infusion every 2 weeks for up to 52 cycles until disease progression or unacceptable toxicity. The primary endpoint was objective response rate (ORR) according to RECIST 1.1 by an Independent Endpoint Review Committee in previously treated pts. The secondary objectives include investigator-assessed ORR, progression-free survival (PFS), overall survival (OS), safety and the association between the efficacy of nivolumab and PD-L1 expression. Results: A total of 56 CUP pts, 45 previously treated and 11 previously untreated pts, were enrolled in this trial. The median age was 65.5 years, 22 pts were male. Median follow-up was 8.05 mo (range, 0.1 to 20.7 mo). Of 45 previously treated pts, 2 and 9 had an investigator-assessed complete response and partial response (ORR 24.4%, 95% CI: 12.9-39.5%), with a median PFS (mPFS) and OS (mOS) of 5.4 mo (95% CI: 2.6-6.9) and 15.1 mo (95% CI: 8.3-NR), respectively. Among 11 previously untreated pts, 1 pt had partial response (ORR 9.1%, 95% CI: 0.2-41.3%). The mPFS was 3.9 mo and the mOS was not reached in untreated pts (95% CI: 1.1-5.6, and 95% CI: 2.6-NR, respectively). Nivolumab demonstrated a mPFS of 5.1mo (95% CI: 2.7-5.6) and a mOS of 15.9 mo (95% CI: 8.4-NR) in an overall population. Immune-related adverse events occurred in 57% of overall pts with 5% of grade 3 or higher, and the most common were rash (27%), hypothyroidism (16%), and diarrhea/colitis (16%). No treatment related death was observed. Conclusions: In pts with previously treated and untreated CUP, nivolumab demonstrated durable antitumor activity with a manageable safety.
