8012 Background: In a phase III superiority study, Pem+carboplatin (Cb)+Bev followed by Pem+Bev improved PFS compared with paclitaxel (Pac)+Cb+Bev followed by Bev in NS-NSCLC pts. Superior OS (primary endpoint) was not met. These analyses assessed the efficacy and safety in pts who received MT. Methods: Prespecified exploratory analyses were performed in the maintenance population (MP) and timed from the start of induction. Pts ≥18 years with stage IIIB/IV NS-NSCLC (ECOG status 0–1) from the multicenter, randomized, open-label, phase III superiority study were included in the MP if they received at least one dose of MT. For MT, pts received intravenous Pem 500 mg/m2+Bev 15 mg/kg (n=292) or Bev 15 mg/kg (n=298). OS, PFS, and safety were evaluated. Comparison is made to the intent-to-treat (ITT; Pem=472, Pac=467) or safety population (SP; Pem=442, Pac=443; received at least one dose of one drug). Results: Baseline pt and disease characteristics for the ITT and MP were similar between arms. In the ITT/MP population, the median number of cycles was 7/10 (range, 1-41/4–41) in the Pem arm and 6/9 (range, 1-39/5–39) in the Pac arm. In the ITT/MP, OS was 12.6/17.7 months (mos; Pem) and 13.4/15.7 mos (Pac). Survival rates (%) at 12 and 24 mos with Pem (ITT/MP) were 52.7/71.7 and 24.4/34.5; Pac, 54.1/66.5 and 21.2/26.5%. In pts not receiving MT, OS was 4.7 mos (Pem) and 6.1 mos (Pac). PFS (mos) in the ITT/MT was 6.0/8.6 (Pem) and 5.6/6.9 (Pac). In pts not receiving MT, PFS was 2.3 mos and 2.5 mos with Pem and Pac, respectively. From induction, both SP/MP had significantly more grade 3/4 thrombocytopenia, anemia, and fatigue with Pem and neutropenia and sensory neuropathy with Pac (p≤0.001). During MT only, the difference in grade 3/4 neutropenia rates between arms was no longer significant. Conclusions: Improved efficacy outcomes were consistent with previous Pem maintenance and Bev studies and no new toxicities were observed. Clinical trial information: NCT00762034.

9554 Background: Tislelizumab is an anti-PD-1 antibody engineered to minimize binding to FcγR on macrophages to abrogate antibody-dependent phagocytosis. Tislelizumab in combination with chemotherapy has demonstrated a manageable tolerability profile and preliminary efficacy as 1L treatment for NSCLC. Methods: In this open-label phase 3 study (NCT03594747), Chinese pts with histologically confirmed stage IIIB or IV sq NSCLC were randomized (1:1:1) to receive IV Q3W: tislelizumab (200 mg, D1) + paclitaxel (P; 175 mg/m2, D1) and carboplatin (carb; AUC 5, D1) ( Arm A); tislelizumab + nab-P (100 mg/m2; D1, 8, and 15) and carb (AUC 5, D1) ( Arm B); or P (175 mg/m2, D1) and carb (AUC 5, D1) ( Arm C). Chemotherapy was administered for 4-6 cycles followed by tislelizumab. Patients were stratified by tumor stage and PD-L1 expression. The primary endpoint, PFS per RECIST v1.1, was assessed by Independent Review Committee; key secondary endpoints included OS, ORR, DoR, and safety/tolerability. Results: Across 360 pts, median PFS was significantly improved with tislelizumab plus chemotherapy ( Arms A and B) compared with chemotherapy alone ( Arm C) (Table). As of 6 Dec 2019, ORRs were higher and median DoRs were longer in Arms A and B vs Arm C. Across all arms, median OS was not reached and median number of treatment cycles were comparable. Adverse events (AEs) leading to discontinuation of any treatment were reported in 12.5%, 29.7%, and 15.4% of pts in Arms A, B, and C, respectively. The most commonly reported grade ≥3 AEs were hematologic in nature (eg, neutropenia) and consistent with known chemotherapy AEs. Serious treatment-related AEs (TRAEs) were reported in 72 pts (37.5% [ A]; 38.9% [ B]; 23.6% [ C]); TRAEs leading to death were reported in 6 pts (n=1 [ A]; n=2 [ B]; n=3 [ C]), none of which were solely attributed to tislelizumab. Conclusions: As 1L treatment for advanced sq NSCLC, addition of tislelizumab to P/carb or nab-P/carb chemotherapy significantly improved PFS and showed higher ORR and longer DoR than chemotherapy alone. The safety profile is in line with the known profiles of tislelizumab, chemotherapy, and underlying NSCLC; no new safety signals were identified with addition of tislelizumab to chemotherapy.

7115 Background: Efficacy and safety in fit, elderly NSCLC pts receiving platinum-based treatment have been reported to be similar to those in younger pts. However, there is controversy about which platinum-based regimens are suitable for the elderly. To compare efficacy and safety of platinum-based chemotherapy regimens in the elderly, we conducted an age specific subgroup analysis on FACS, a phase III randomized trial comparing four platinum-based regimens for advanced NSCLC. Methods: FACS was designed to compare three platinum-based combination regimens to cisplatin (80 mg/m2, day 1) plus irinotecan (60 mg/m2, days 1, 8, 15) (IP) as the reference arm. The experimental regimens were: carboplatin (AUC 6, day 1) plus paclitaxel (200 mg/m2, day 1) (TC); cisplatin (80 mg/m2, day 1) plus gemcitabine (1000 mg/m2, days 1, 8) (GP); cisplatin (80 mg/m2, day 1) plus vinorelbine (25 mg/m2, days 1,8) (NP). Results: Of the 105 pts ≥ 70 years (17% of 602 enrolled pts), 27 were on the IP arm, 27 on TC, 28 on GP, and 22 on NP. Patient characteristics were similar in each arm. Response rates were 26% in IP, 20% in TC, 32% in GP, 50% in NP. Frequency of grade 3 or greater leukocytopenia (IP/TC/GP/NP: 52%/33%/36%/86%) was higher in NP, and thrombocytopenia (IP/TC/GP/NP: 11%/19%/43%/0%) was higher in GP, however anemia (IP/TC/GP/NP: 56%/19%/29%/55%) was lower in TC and GP. Frequency of grade 2 or greater vomiting (IP/TC/GP/NP: 52%/22%/39%/41%) was lower in TC, and diarrhea (IP/TC/GP/NP: 48%/7%/4%/14%) was lower in TC, GP and NP, however, grade 2 or greater sensory neuropathy (IP/TC/GP/NP: 0%/22%/0%/0%) was higher in TC. One year survival rates were 48% for the IP arm, 48% for TC, 61% for GP, and 46% for NP. There were no significant survival differences between IP and each experimental regimen. In addition, no significant differences between ≥ 70 and < 70 years were observed in each treatment regimen regarding hematological and non-hematological toxicities, response rates, and survival, except that grade 3 or greater anemia was significantly higher in ≥ 70 years pts in IP and NP arms. Conclusions: These platinum-based four regimens were similarly active and tolerable for fit, elderly NSCLC pts, and their efficacy and toxicity in the elderly were similar to those in younger pts. No significant financial relationships to disclose.

53 Background: Treatment (tx) impact on pt quality of life (QoL) informs pt and physician choices in the management of NSCLC. QoL, a secondary endpoint of POINTBREAK, was assessed using the patient-reported Functional Assessment of Cancer Therapy General (FACT-G), Lung (FACT-L), and Neurotoxicity (FACT&GOG-Ntx). Methods: Pts with previously untreated stage IIIB/IV NS-NSCLC and ECOG performance status 0-1 were randomized to receive induction Pem+Cb+Bev or Pac+Cb+Bev for up to 4 cycles. Pts without progressive disease received maintenance Pem+Bev (Pem Arm) or Bev (Pac Arm). Pts completed the FACT-G [physical, emotional, functional, and social well-being subscales (SS)], FACT-L (FACT-G + lung cancer SS), and FACT&GOG-Ntx (FACT-G + Ntx SS) at each visit. SS score and total score (TS) were calculated for each instrument. Tx group differences were analyzed using Linear Mixed Effects model. Toxicity was investigator assessed using CTCAE and was compared with Fisher’s exact test. Results: The primary endpoint of superior OS for the Pem arm was not met and is reported elsewhere. Pt overall compliance on the FACT was 91.2% (Pem Arm) and 90.0% (Pac Arm). For both the FACT-G and FACT-L TS, no overall significant change from baseline difference was observed between the Pem and Pac Arms. No overall differences were seen in SS scores except for Ntx. Pts on the Pem Arm had significantly less change from baseline in Ntx SS score and Ntx TS than pts in the Pac Arm at cycle 2 (p<0.001), and this significant tx effect persisted through induction and the six cycles of maintenance considered in the analysis. Significantly fewer pts on the Pem Arm experienced investigator assessed Grade 3/4 sensory neuropathy compared to the Pac Arm (0.0% vs. 4.1%, p<.00001). Conclusions: Based on the FACT results, pts on the Pem and Pac Arms reported similar changes in QoL except for less change from baseline in Ntx on the Pem Arm. Patient-reported Ntx is consistent with the clinically-measured drug-related Grade 3/4 sensory neuropathy.

3507 Background: X, an orally administered non-peptide neurotrophic agent developed by sanofi-aventis, was shown in vitro to minimize neuritic damage induced by Ox (co-culture of Schwann cells and dorsal roots ganglia explant). The probability of occurrence of Grade (Gr) 3–4 PSN at a cumulative dose of Ox of 1000 mg/m2, was consistently reported to be of 18–20%. Methods: First line MCRC pts were randomized to receive, in a DB fashion, FOLFOX4 and either Plcb or X 1mg daily. X was administered from the 1st day of chemotherapy till 15 days post last Ox cycle. Co-primary objectives were reduction in the risk of occurrence of Gr 3–4 PSN relative to cumulative dose of Ox (Kaplan-Meier method) and non-inferiority in response rate (RR). Secondary endpoints included evaluation of sensory action potential (SAP) and safety. Results: From July 2002 to May 2004, 649 pts were randomized (324 Plcb, 325 X). Pts characteristics were well balanced across arms, median number of Ox cycles was 12 in both arms, median relative dose intensity (%) was 83.8 (Plcb) and 85.2 (X). A significant risk reduction of 39% in the probability of Grade 3–4 PSN in favor of X was reported (hazard ratio [95% CI] = 0.61 [0.40; 0.93], p= 0.0203). Overall RR [95 % CI] was: Plcb 42.6% [37.1; 48.2] and X 44.9% [39.4; 50.6]. As prospectively defined in the protocol, the lower bound of the CI of the RR ratio above 0.8 confirms noninferiority in RR (1.055 [0.88; 1.26]). In both arms the mean % of change in SAP worsens as a function of PSN severity. 17.3 (Plcb) and 13.5% (X) of the pts discontinued Ox because of PSN. Severe toxicities (% Gr 3–4), reported with a ≥2% difference between arms, were (plcb vs X): diarrhea 10.9 vs 13.0, pulmonary embolism 0.9 vs 3.1, fatigue 3.7 vs 1.5, neutropenia 43.0 vs 37.8. Conclusion: X was shown to be efficient in reducing the risk of Grade 3–4 oxaliplatin-induced PSN without impacting FOLFOX4 antitumor activity. No significant financial relationships to disclose.

9014 Background: ECHO-202/KEYNOTE-037 is an open-label, phase 1/2 study of epacadostat (a potent and selective oral inhibitor of the immunosuppressive enzyme indoleamine 2,3-dioxygenase 1) plus pembrolizumab (E + P) in patients (pts) with advanced tumors. We report preliminary efficacy and safety outcomes for the phase 1/2 NSCLC cohort. Methods: Adult pts with prior platinum-based therapy (tx) and no prior checkpoint inhibitor tx were eligible. Phase 1 dose-escalation tx was E (25, 50, 100, 300 mg PO BID) + P (2 mg/kg or 200 mg IV Q3W); MTD was not exceeded. E (100 mg BID) + P (200 mg Q3W) tx doses were selected for phase 2 cohort expansion. Efficacy was evaluated by tumor proportion score (TPS [% viable tumor cells, PD-L1 staining]: < 50% and ≥50%) and by prior lines of tx in RECIST 1.1 evaluable pts. Safety was assessed in pts receiving ≥1 E + P dose. Results: As of 29OCT2016,43 pts (phase 1, n = 12; phase 2, n = 31) were evaluated. Median age was 65 years, 58% of pts were women, 12% were EGFR-positive, and 23% were KRAS-positive. Most pts had a history of smoking (84%), ≤2 prior lines of tx (84%), and no prior TKI tx (93%). For the 40 efficacy-evaluable pts, ORR (CR+PR) and DCR (CR+PR+SD) were 35% (14/40; 14 PR) and 60% (24/40; 10 SD), respectively. PD-L1 TPS test results were available in 28/40 efficacy-evaluable pts. ORR and DCR for pts with TPS ≥50% and ≤2 prior tx were 43% (3/7; all PR) and 57% (4/7; 1 SD), respectively; for pts with TPS < 50% and ≤2 prior tx, ORR and DCR were 35% (6/17; all PR) and 53% (9/17; 3 SD). Among the 40 efficacy-evaluable pts, 12/14 responses were ongoing (range, 1+ to 519 days) at data cutoff. PFS and biomarker analyses are ongoing. Across all 43 pts, most frequent TRAEs were fatigue (19%), arthralgia (9%), and increased AST (9%); 16% of pts had grade ≥3 TRAEs, and increased lipase (asymptomatic) was the only grade ≥3 TRAE that occurred in > 1 pt (n = 2). Two pts discontinued due to TRAEs (grade 3 increased AST, grade 2 increased ALT [n = 1]; grade 2 brain edema [n = 1]). Conclusions: E + P was generally well tolerated and associated with promising responses in pts with NSCLC. A phase 3 NSCLC study is planned. Clinical trial information: NCT02178722.
