4009 Background: Interim analysis of a global, phase 2 KEYNOTE-059 study (NCT02335411) reported manageable safety and promising antitumor activity for pembro alone or pembro + chemo in pts with G/GEJ cancer. Here we report long-term efficacy and safety data of all cohorts. Methods: Pts with recurrent or metastatic G/GEJ adenocarcinoma were enrolled in 3 cohorts. Cohort 1 pts (PD-L1–positive or –negative) received pembro alone after ≥2 prior lines of therapy. Cohort 2 pts (PD-L1–positive or –negative) received pembro + cisplatin (80 mg/m2 day 1) + 5-fluorouracil (800 mg/m2 days 1-5 Q3W) or capecitabine (in Japan only, 1000 mg/m2 twice daily) as first-line. Cohort 3 pts (PD-L1–positive, combined positive score ≥1% using the PD-L1 IHC 22C3 pharmDx assay) received pembro alone as first-line. All pts received pembro 200 mg Q3W for up to 2 years. End points included safety, ORR, DOR, and OS. Results: At data cutoff (Aug 8, 2018), median (range) follow-up was 6 (1-38), 14 (2-40), and 21 (2-36) months for cohorts 1 (n = 259), 2 (n = 25), and 3 (n = 31), respectively. In cohort 1, confirmed ORR (95% CI) was 11.6% (8-16) overall, 15.5% (10-22) in PD-L1–positive, and 6.4% (3-13) in PD-L1–negative tumors. In cohort 2, confirmed ORR was 60.0% (39-79) overall, 73.3% (45-92) in PD-L1–positive, and 37.5% (9-76) in PD-L1–negative tumors. In cohort 3, confirmed ORR was 25.8% (12-45). Median (range) DOR in months was 16.1 (2-35+), 4.6 (3-37+), and not reached (2.1-32.5+) in cohorts 1, 2, and 3, respectively. OS at 1 year/2 years was 24.6%/12.5%, 52%/32%, and 63.6%/40.1% in cohorts 1, 2, and 3, respectively. In cohorts 1, 2, and 3, grade 3-5 treatment-related adverse event (TRAE) incidence was 46 (18%), 20 (80%), and 8 (26%) respectively. TRAEs led to discontinuation in 6 (2%) and 3 (12%) pts in cohorts 1 and 2, respectively, and to death in 2 (1%) pts in cohort 1. No TRAEs led to discontinuation or death in cohort 3. Conclusions: These updated results demonstrate manageable safety, durable clinically meaningful activity of pembro in heavily pretreated pts, and promising efficacy of first-line pembro (alone or + chemo) in pts with advanced G/GEJ cancer. Clinical trial information: NCT02335411.

7502 Background: In PACE (NCT01207440) heavily pretreated patients (pts) with chronic-phase CML (CP-CML) had deep, lasting responses to PON; long-term follow-up showed increasing rates of arterial occlusive events (AOEs). We present IA results from OPTIC (NCT02467270), evaluating the association between PON exposure, efficacy, and safety, and response-based dose reduction in pts with CP-CML. Methods: This ongoing, multicenter, randomized phase 2 trial enrolled pts with CP-CML resistant or intolerant to ≥2 TKIs or with a T315I mutation to receive PON at a starting dose of 45 mg (cohort A), 30 mg (B), and 15 mg (C) qd. Doses were reduced to 15 mg qd on achievement of ≤1% BCR-ABL1IS in A/B. Primary endpoint: 12 mo ≤1% BCR-ABL1IS; secondary endpoints include cytogenetic and molecular response and AOE, VTE, and TEAE rates. Results are descriptive at this IA and will be inferential by adjusting multiplicity across 3 cohorts at final analysis. Results: 283 pts were randomized (A/B/C: n = 94/95/94); median age 48 y (18‒81 y). 26% had hypertension history; 2/43/55% received 1/2/≥3 TKIs; 40% had ≥1 baseline (BL) mutations, with 23% T315I. At IA data cutoff (20 Jul 2019), 162 pts (57%; n = 57/51/54) remained on study treatment. Among 282 pts in the safety population, median duration of exposure was ≈1 y (A/B/C, 12.9/11.2/11.0 mo). At 12 mo, 39% (95% CI, 27.6, 50.6), 27% (17.6, 39.1), and 26% (16.5, 38.6) in A, B, and C, respectively, achieved ≤1% BCR-ABL1IS. Additional efficacy in Table. Dose reductions due to efficacy (A/B): 35/21%. Most common TEAEs (any grade/≥3): thrombocytopenia 39/27%, neutropenia 25/17%. AOEs/serious AOEs were reported by (A, B, C) 5%/2%, 4%/3%, and 1%/0%. Dose reductions due to TEAEs: (A/B/C): 44/31/28%; discontinuations due to TEAEs: 18/15/14%. There were 4 (1.4%) on-study deaths; A, sudden death, n = 2; C, pneumonia, n = 2; no deaths were due to AOEs. Clinical trial information: NCT01207440 . Conclusions: OPTIC IA shows a trend toward dose-dependent efficacy and safety and may provide a refined understanding of the PON benefit:risk profile and its relation to dose. Data from longer follow-up may support an alternate dosing regimen for pts with CP-CML. [Table: see text]

10 Background: For men with mCRPC, systemic therapies such as docetaxel and cabazitaxel improve survival, but more effective treatments are needed. KEYNOTE-365 (NCT02861573) is a phase 1b/2 study to examine the safety and efficacy of pembro in combination with 4 different study medications (cohorts A, B, C, D) in mCRPC. Previous data from cohort B with a median of 20 months of follow-up showed that pembro + docetaxel and prednisone was well tolerated and had antitumor activity in patients (pts) with mCRPC previously treated with abi or enza. New efficacy and safety data after an additional year of follow-up are presented. Methods: Cohort B enrolled pts who did not respond to or were intolerant to ≥4 weeks of abi or enza in the prechemotherapy mCRPC state and whose disease progressed within 6 months of screening (determined by PSA progression or radiologic bone/soft tissue progression). Pts received pembro 200 mg IV every 3 weeks (Q3W), docetaxel 75 mg/m2 IV Q3W, and oral prednisone 5 mg twice daily. Primary end points were safety, PSA response rate (PSA decrease >50% from baseline), and ORR per RECIST v1.1 by blinded independent central review. Efficacy and safety were assessed in all pts as treated. Results: Of the 104 treated pts, median age was 68.0 years (range, 50-86), 23.1% had PD-L1–positive tumors (combined positive score ≥1), 25.0% had visceral disease, and 50.0% had measurable disease. Median time from enrollment to data cutoff was 32.4 months (range 13.9-40.3); 101 pts discontinued, primarily because of disease progression (77.9%). Efficacy outcomes are reported in the table below. Treatment-related adverse events (TRAEs) occurred in 100 pts (96.2%); the most frequent (≥30%) were diarrhea (41.3%), fatigue (41.3%), and alopecia (40.4%). Grade 3-5 TRAEs occurred in 46 pts (44.2%). Five pts (4.8%) died of AEs; 2 were treatment-related pneumonitis. Conclusions: After another year of follow-up, pembro + docetaxel and prednisone showed improved ORR and PSA response rates compared to the prior dataset in pts with mCRPC previously treated with abi or enza. Safety was consistent with known profiles of each agent and will be further evaluated in a phase 3 study (KEYNOTE-921). Clinical trial information: NCT02861573. [Table: see text]

e602 Background: The clinical experience with CBZ in mCRPC patients (pts) has enriched notably since its approval for clinical use, but there is still a lack of well-defined prognostic/predictive factors to better characterize the profile of pts that could achieve the best therapeutic benefit. Analysis of the final expanded cohort and mature long-term follow-up are presented. Methods: Medical records from mCRPC pts progressing during or after docetaxel and treated with CBZ at 21 centres in Spain were reviewed retrospectively. Baseline characteristics, overall survival (OS), radiographic progression-free survival (rPFS), and toxicity were collected. Univariate and multivariate analysis of a variety of factors predicting OS were conducted. Results: 187 consecutive pts (median age 69) with intermediate-poor prognostic baseline characteristics (Table 1) received a median of 6 cycles (range 2-59) of CBZ. Median OS from first CBZ cycle was 15.3 [CI: 11.7; 18.0] months (mo) and median clinical and/or rPFS was 7.9 mo [CI: 6.8; 10.3]. Gleason score (GS) < 8 (vs ≥ 8), time under first-line androgen deprivation therapy (ADT) ( > 16.1 (median) vs < 16.1 mo) and the number of chemotherapy lines before CBZ did not significantly influence OS. Median follow-up was 9.5 mo. Febrile neutropenia occurred in 4 pts and 1 pt had neutropenic infection. Main nonhematologic grade ≥ 3 toxicities were asthenia (2.7%) and diarrhea (1.6%). Alopecia, nails disorders and peripheral neuropathy were uncommon. Conclusions: CBZ administered in the daily clinical practice is associated with consistent OS, similar to that observed in pivotal clinical trials. GS, median time under first-line ADT and number of chemotherapy lines before CBZ did not influence clinical benefit. CBZ has an acceptable safety profile. Funding: Sanofi [Table: see text]

4014 Background: In the phase 3 ONO-12 study, 3rd- or later-line nivolumab (N) monotherapy prolonged OS vs placebo in Asian pts with adv G/GEJ cancer (median OS, 5.3 vs 4.1 mo; HR, 0.63; P < 0.0001; ASCO-GI 2017, Kang YK et al. J Clin Oncol. 2017;35 (suppl 4S) [abstract 2]). The phase 1/2 CheckMate 032 study showed favorable clinical activity of N ± ipilimumab (I) in Western pts with adv CTx-R G/E/GEJ cancer (NCT01928394). We report updated long-term follow-up data of G/E/GEJ pts in CheckMate 032. Methods: Pts received N 3 mg/kg Q2W (N3), N 1 mg/kg + I 3 mg/kg Q3W (N1+I3), or N 3 mg/kg + I 1 mg/kg Q3W (N3+I1). Primary endpoint was ORR. Secondary endpoints included DOR, OS, PFS, and safety. Efficacy in pts by PD-L1 status was assessed. Results: 160 heavily pretreated pts (79% had ≥ 2 prior Tx) were enrolled (N3, n = 59; N1+I3, n = 49; N3+I1, n = 52); 24% had PD-L1+ (≥ 1%) tumors. ORR was 12% in N3, 24% in N1+I3, and 8% in N3+I1. In pts with PD-L1 ≥ 1%, ORR was 19% (3/16) in N3, 40% (4/10) in N1+I3, and 23% (3/13) in N3+I1; in pts with PD-L1 < 1%, ORR was 12% (3/26), 22% (7/32), and 0% (0/30), respectively. Median DOR was 7.1 mo in N3, 7.9 mo in N1+I3, and NA in N3+I1. OS in all pts and in pts with PD-L1 ≥ 1% is in the Table. Grade 3–4 treatment-related AEs reported in ≥ 10% of pts in any treatment arm were diarrhea (N3, 2%; N1+I3, 14%; N3+I1, 2%), ALT increased (N3, 3%; N1+I3, 14%; N3+I1, 4%), and AST increased (N3, 5%; N1+I3, 10%; N3+I1, 2%). Conclusions: N ± I led to durable responses and long-term OS in heavily pretreated Western pts with adv G/E/GEJ cancer, which is consistent with the clinical activity observed in Asian pts in the ONO-12 study. Safety was consistent with prior reports. These data support ongoing investigation of N ± I in pts with adv G/E/GEJ cancer. Clinical trial information: NCT01928394. [Table: see text]

Abstract Introduction Prognosis for relapsed and refractory large B-cell lymphoma (r/r LBCL) is poor, and treatment remains challenging. Relmacabtagene autoleucel (relma-cel) is a CD19-directed 4-1BB/CD3z chimeric antigen receptor T cell (CAR-T) product manufactured in China. RELIANCE study is the first CAR-T study with CD19 as target that got IND approved by the authority in China. Initial findings of the pivotal Phase 2 single-arm, multicenter RELIANCE trial demonstrated high response rates and low rates of CAR-T-associated toxicity with relma-cel treatment in heavily pretreated patients (pts) with r/r LBCL (NCT04089215; Ying et al. Cancer Med 2020;10:999-1011). Long-term follow-up data for the RELIANCE study are presented. Materials & Methods Fifty-nine adults (age ≥18 years) with heavily pretreated (≥2 prior therapies), measurable and histologically confirmed r/r LBCL were randomized to receive lymphodepletion chemotherapy (LDC: fludarabine 25 mg/m 2 + cyclophosphamide 250 mg/m 2 daily×3) followed by a single infusion of autologous CAR+ T cells at a dose of 100×10 6 or 150×10 6. Pts were evaluated for efficacy using Lugano criteria and for toxicity using Common Terminology Criteria for Adverse Events v4.03 and for cytokine release syndrome (CRS) using Lee et al. (Blood 2014;124(2):188-95). Primary endpoint was 3-month objective response rate (ORR); key secondary endpoints included complete response rate (CRR) at 3 months, duration of response (DOR), progression-free survival (PFS), overall survival (OS) and treatment-emergent adverse event (TEAE) profile. The data cutoff date was December 31, 2020. Results At the time of analysis, all 59 pts (median age 56.0 years, range 18-75 years) were at least 15 months post-treatment with relma-cel (7 pts completed trial, 34 pts on study, 18 pts withdrew). Among the modified intent-to-treat (mITT) population of 58 efficacy-evaluable pts, best ORR was 77.6%, with a best CRR of 51.7%; ORR and CRR at 3-month-postdose landmark were 60.3% and 44.8%, respectively. With a median follow-up of 17.9 months (range 0.3-25.6 months), median PFS (mITT) was 7.0 months (95% CI 4.8-not reached [NR]). Median PFS was NR (95% CI 8.8 months-NR) for pts with compete response (CR) at 3 months, the 6-, 12-, 18- and 24-month PFS rates were 80.8%, 69.2%, 69.2% and 69.2%, respectively (Figure). PFS was associated with objective response or CR at 1, 3, 6, and 12 months (log-rank test, p≤0.002). Median OS was NR (95% CI NR-NR) for both the mITT population and pts with CR at 3 months (12-month OS rate, 76.8% and 92.3%, respectively). Median DOR was NR (95% CI 4.9 months-NR) for the mITT population and (95% CI 8.0 months-NR) for pts with CR at 3 months. Levels of CAR-T cells declined to below the level of quantification (BLQ) in 41 (69.5%) pts, among whom nearly 40% had sustained response. Median time from documentation of CAR-T BLQ to disease progression was 6.1 months (95% CI 1.8-NR). Treatment-related TEAEs were reported in 93.2% of pts and were primarily grade 1-2 (89.8% pts); 54.2% of pts had grade ≥3 TEAEs. Pyrexia was the most common TEAE, reported in 59.3% of pts (all grade 1-2). The most common grade ≥3 treatment-related TEAEs were neutrophil count decrease (30.5%) and white blood cell (WBC) count decrease (13.6%). Presence of cytopenia at day 29 (78.0%) was significantly associated with WBC count after LDC, change in serum albumin between days 1 and 4 and serum interleukin 8 after LDC (p&lt;0.05). The incidence of CRS and neurotoxicity (NT) was 47.5% and 20.3%, respectively, both primarily grade 1-2. There were no CRS- or NT-related deaths. Occurrence of grade ≥2 CRS or NT (11.9% and 6.8%, respectively) was significantly associated with fold-change of platelet count on day 4 compared with baseline and day 1 absolute neutrophil count (p&lt;0.03). There were no treatment-related deaths. Conclusions These are the first data of long-term follow-up CD19 CAR-T study with IND approval in China reported. With nearly 18 months of median follow-up, the RELIANCE pivotal registered study demonstrated durable responses, high rates of OS and PFS, and no new safety profile found in r/r LBCL pts. Based on these data, relma-cel is undergoing approval in China. Figure: Kaplan-Meier estimates of (A) PFS and (B) OS by 3-month tumor response PR, partial response Figure 1 Figure 1.

6032 Background: A phase III multicenter prospective randomized controlled trial was conducted to compare cisplatin plus 5-fluorourcil with or without docetaxel as first-line induction chemotherapy in the patients with locoregionally advanced nasopharyngeal carcinoma (LANPC). Here, we report on the long-term outcomes and late toxicities of the trial (NCT01536223). Methods: Patients with newly diagnosed LANPC, stage III-IV disease, Karnofsky performance score≥70, without metastasis were eligible and randomly assigned 1:1 to TPF versus PF for three cycles. The primary end point was progression-free survival; local control, OS and advent events were important key secondary end points. The Kaplan-Meier method and the log-rank test were used to conduct and compare the survival curves in this study. Results: Two hundred ninety-nine patients were enrolled. 276 patients (138 TPF and 138 PF) were evaluable. Baseline characteristics were well-balanced between two groups, and the median age was 48 (range, 18-60 years). The ORR rates after induction chemotherapy and chemoradiotherapy were 90.6% and 9797.8% in TPF group and 87.0% (P > 0.05) and 97.8% (P > 0.05), respectively. The median follow-up was 99 months. For all patients, the 5- and 8-year OS and PFS were 76.9% and 74.9%, 72.3% and 69.1%, respectively. PF was associated with a similar PFS versus TPF ( 5-year PFS of 72.4% versus 73.2%, P =.747), and an equivalent OS at 5 years ( 79.2% and 79.1%, P = 0.519). Treatment-related grade 3 to 4 advent events were less frequent with PF compared with TPF. Conclusions: With prolonged follow-up, the survival outcomes in the PF group were not non-inferiority to those in the TPF group, but grade 3 to 4 advent events were less frequent. Clinical trial information: NCT01536223.
