The Impact

247 Background: It is unclear whether prior treatment with ramucirumab (RAM) or RAM plus paclitaxel (PAC), standard second-line treatments for metastatic gastric or gastroesophageal junction cancer (mGC/GEJC), can influence outcomes with third-line chemotherapy in this patient (pt) population (pop). In the phase 3 TAGS trial, FTD/TPI showed a survival benefit vs placebo (PBO) in pts with mGC/GEJC who had received ≥2 prior chemotherapy regimens. Post hoc analyses were performed to assess the impact of prior RAM, PAC or RAM+PAC treatment on the efficacy and safety of FTD/TPI in TAGS. Methods: Pts in the TAGS trial were categorized into 5 subgroups based on prior treatment received as follows: A) RAM (alone or combined with other agents), B) no RAM, C) PAC (but no RAM), D) RAM+PAC (sequentially or in combination) and E) neither PAC nor RAM. While subgroups A and B were prespecified, all other subgroups were identified post hoc. Efficacy (overall survival [OS] and progression-free survival [PFS]) and safety were assessed in these subgroups. Results: In the overall pop (N=507), 33% had received prior RAM (alone/combined); 30% prior RAM+PAC; 27% prior PAC but no RAM; and 40% had received neither PAC nor RAM. As only 3% of all pts received prior RAM but no PAC, that subgroup was not considered in this analysis. FTD/TPI treatment was consistently associated with benefits in OS and PFS vs placebo across all pt subgroups (Table). Among pts randomized to FTD/TPI, OS benefit was similar between pts who received RAM+PAC vs those who received neither (HR, 1.15; 95% CI, 0.84–1.58) and between pts who received PAC (but no RAM) vs those who received neither (HR, 0.91; 95% CI, 0.66–1.25). The FTD/TPI safety profile was consistent across all subgroups, with similar overall incidences of grade ≥3 adverse events (AEs). Minor variations in hematologic toxicities were noted (Table). Conclusions: In the phase 3 TAGS trial, FTD/TPI treatment in the third or later line provided efficacy benefits vs PBO and demonstrated a consistent safety profile in pts with mGC/GEJC regardless of prior treatments. Clinical trial information: NCT02500043. [Table: see text]

4039 Background: FTD/TPI was approved in 2015 for pretreated pts with mCRC based on the phase 3 RECOURSE trial. FTD/TPI recently demonstrating significantly improved overall survival vs placebo in pretreated pts with mGC/mGEJC in the phase 3 TAGS trial. Methods: We evaluated the pooled safety of FTD/TPI in TAGS and RECOURSE in all pts who received ≥1 dose of FTD/TPI (safety population). Pts were required to have ECOG PS 0/1 and to have received ≥2 previous chemotherapy lines. Results: FTD/TPI and placebo were administered to 335 and 168 pts, respectively, in TAGS, and 533 and 265 pts in RECOURSE. Baseline characteristics were balanced across treatment groups and reflected the disease populations. In the pooled population, 66% of pts were men and 75% had received ≥3 prior systemic treatments. The safety profile of FTD/TPI was comparable between studies (table). In TAGS and RECOURSE, the most common any-cause grade (gr) ≥3 AEs in FTD/TPI-treated pts were neutropenia (34%; 35%), anemia (19%; 17%), and leukopenia (9%; 13%). Gr ≥3 febrile neutropenia occurred in 2% and 4% of pts and gr ≥3 GI AEs in 21% and 12%. Gr ≥3 cardiac AEs were reported in 1% of FTD/TPI-treated pts (both studies), in contrast to results obtained with other third-line agents. Similar proportions of FTD/TPI-treated pts in both studies had AEs leading to dosing delay, dose reduction, or treatment discontinuation. Dosing delay was used more often than dose reduction to manage AEs. TRAEs leading to death occurred in one FTD/TPI-treated pt ( < 1%) in each trial. Conclusions: In a pooled analysis, FTD/TPI was well tolerated with a consistent safety profile in pts with mGC/mGEJC or mCRC. The most frequent AEs were hematologic and GI, which were managed with dosing delays/dose reductions. Clinical trial information: NCT02500043; NCT01607957. [Table: see text]

4065 Background: The international phase III study ToGA has recently shown that TRA is effective in prolonging survival in HER2-positive MGC. However, few data are available for TRA as part of routine clinical practice. Methods: This non-interventional observational study was conducted to evaluate the efficacy, safety and feasibility of TRA in previously untreated pts with HER2-positive MGC. Results: Between Apr 2010 and Jan 2012, data from 110 pts were collected. All pts were evaluable for safety. Baseline pt characteristics were as follows: median age 63 yrs (range 29–88); gender (male 70%; female 29%); ECOG PS (0: 25%; 1: 50%; 2: 15%; 3: 5%); distant mets (91%); liver mets (54%), lymph node mets (35%); peritoneal carcinomatosis (23%). The median duration of TRA treatment was 4.4 months (0–17.1). According to the schedule of chemotherapy TRA was administered every 2–3 wks in a median dose of 4–6 mg/kg BW. Only 28% of pts received TRA according to the label in combination with cisplatin and 5-FU or capecitabine. The remainder received: cisplatin, 5-FU and leucovorin (17%); 5-FU, leucovorin, oxaliplatin and docetaxel (8%); 5-FU, leucovorin and oxaliplatin (7%); capecitabine (6%); other combinations (25%); TRA monotherapy (7%). Although most pts didn’t receive cisplatin-based therapy, preliminary median progression-free survival was 6.8 months, thus comparable to the ToGA data. Most common adverse events (AEs, all grades) were diarrhoea (7%), vomiting (5%) and nausea (5%). Most common grade 3/4 AEs were vomiting (3%), nausea (2%) and fatigue (2%). Health-related quality of life as assessed by EORTC QLQ-C30 and QLQ-STO22 remained stable during observation time. An updated analysis of approx. 200 pts will be presented at the meeting. Conclusions: TRA combined with diverse chemotherapies is safe and effective in the routine treatment of MGC. Cisplatin-free less toxic regimens are feasible and equally effective. The results are in line with those from the ToGA trial and suggest that treatment with TRA should be regarded as standard of care for pts with HER2-positive MGC.

The Impact

6 Background: ENZA increased median overall survival (OS) by 4.8 mo (P <0.001, HR 0.63) vs placebo (PBO) in metastatic castration-resistant prostate cancer (mCRPC) patients (pts) post-docetaxel in AFFIRM (HI Scher et al, NEJM 2012). Corticosteroids (CS) can activate AR signaling in nonclinical models (J Richards, Can Res 2012). In a multivariate model of AFFIRM data baseline CS use was associated with reduced OS (HI Scher et al. ESMO 2012 abstract 899PD). The impact of CS use during study treatment in AFFIRM was evaluated to test if concomitant CS use is also associated with inferior outcomes. Methods: Pts were randomized 2:1 to ENZA 160 mg/d or PBO. Pts were allowed but not required to take CS. OS was the primary endpoint. In a post-hoc analysis On-study CS use was defined as oral CS user for ≥ 1 day on study. Results: On study CS use was 48% in ENZA and 45% in PBO pts. Prognostic factors were slightly better in the no CS group compared to the CS group. Use of CS regardless of treatment was associated median OS of 11.5 mo (95% CI: 10.5, 13.0) for CS pts vs median OS NM (NM, NM) for no CS pts (HR=0.40; 95% CI: 0.33, 0.48). ENZA was consistently superior to PBO for OS, radiographic progression free survival (rPFS) and time to PSA progression (TTPP), regardless of CS use (Table). Pts on CS had higher rates of grade 3 - 4 adverse events (AE) compared to no CS pts: 63.3% vs 34.4% respectively. Conclusions: In this post-hoc analysis, on study CS use was associated with reduced OS and higher rates of grade 3 -4 AEs in mCRPC pts post-docetaxel. While CS pts had worse outcomes, ENZA was consistently superior to PBO regardless of on study CS use. The inferior outcomes in CS pts may be due to unmeasured confounders or the biologic properties of CS use itself. Clinical trial information: NCT00974311. [Table: see text]

4002 Background: CheckMate 649 is the largest randomized, global phase 3 study of 1L programmed death (PD)-1 inhibitor–based therapy in GC/GEJC/EAC. 1L NIVO + chemo demonstrated superior overall survival (OS) vs chemo, with progression-free survival (PFS) benefit and an acceptable safety profile in pts whose tumors expressed PD-ligand (L)1 at combined positive score (CPS) ≥ 5 and ≥ 1, and in all randomized pts (Moehler et al. Ann Oncol 2020). We report additional data for all randomized pts. Methods: Eligible pts had previously untreated, unresectable advanced or metastatic GC/GEJC/EAC. Known HER2-positive pts were excluded. Pts were randomized to receive NIVO (360 mg Q3W or 240 mg Q2W) + chemo (XELOX Q3W or FOLFOX Q2W), NIVO + ipilimumab, or chemo. Dual primary endpoints for NIVO + chemo vs chemo were OS and PFS by blinded central review in PD-L1 CPS ≥ 5 pts. Hierarchically tested secondary endpoints were OS in PD-L1 CPS ≥ 1 and all randomized pts. Results: At 12-month minimum follow-up for 1581 randomized pts, NIVO + chemo had a statistically significant OS benefit vs chemo (HR 0.80 [99.3% CI 0.68–0.94; P = 0.0002]) in all randomized pts; PFS benefit was also seen (HR 0.77 [95% CI 0.68–0.87]). OS benefit was observed in multiple prespecified subgroups, consistent with the primary population. Grade 3–4 treatment-related adverse events (TRAEs) were reported in 59% (NIVO + chemo) and 44% (chemo) of pts. TRAEs with potential immunologic etiology (select TRAEs; sTRAEs) are shown in the table. Pts in the NIVO + chemo arm had decreased risk of symptom deterioration on treatment vs those in the chemo arm (HR 0.77 [95% CI 0.63–0.95; P = 0.0129]). Tolerability as measured by the FACT-Ga GP5 item was similar in both treatment groups. Conclusions: The addition of NIVO to chemo demonstrated improved OS and PFS benefit in all randomized pts, along with an acceptable safety profile and maintained tolerability as well as QoL, providing further support for NIVO + chemo as a standard 1L treatment for advanced GC/GEJC/EAC.

167 Background: The programmed death-1 receptor (PD-1) and its ligand (PD-L1) are key therapeutic targets in the reactivation of the immune response against cancer. Avelumab* (MSB0010718C) is a fully human anti-PD-L1 IgG1 antibody being investigated in clinical trials. We report safety and clinical activity of avelumab in patients (pts) with advanced gastric or gastroesophageal junction adenocarcinoma (GC/GEJ) based on level of PD-L1 expression. This phase Ib JAVELIN study (NCT01772004) enrolled pts who had progressed on prior therapy ( ≥ 2L) and pts who had received 1L chemotherapy but had not yet progressed (switch-maintenance [Mn]) Methods: Pts received avelumab 10 mg/kg Q2W until confirmed progression, unacceptable toxicity, or withdrawal. Tumours were assessed every 6 wks (RECIST 1.1). Best overall response and progression-free survival (PFS) were evaluated. Adverse events (AEs) were graded by NCI-CTCAE v4.0. PD-L1 expression was assessed by immunohistochemistry using various cutoff criteria Results: As of Feb 13, 2015, 75 pts with GC/GEJ were treated with avelumab (20 pts, 2L; 55 pts, Mn). Treatment-related treatment-emergent AEs (TR-TEAEs) of any grade occurred in 47 pts (62.7%); the most common ( > 10%) was infusion-related reaction (12 [16.0%], all grade 1/2). Nine pts (12.0%) reported a grade ≥ 3 TR-TEAE, including fatigue (2), thrombocytopenia (2), and anemia (2; each 2.7%). There was 1 treatment-related death (hepatic failure/autoimmune hepatitis). Responses were observed in 7 pts (3/20 2L, all PRs; 4/55 Mn, 1 CR, 3 PRs). PD-L1 expression was evaluable in 55 pts (12/20 2L, 43/55 Mn), including in 3 pts with a response. Median PFS in 2L group was 36.0 wks (95% CI: 6.0, 36.0) for PD-L1+ and 11.6 wks (2.1, 21.9) for PD-L1− ( ≥ 1% cutoff). In Mn group, median PFS for PD-L1+ and PD-L1− status was 17.6 wks (5.9, 18.0) and 11.6 wks (5.7, 17.7), respectively ( ≥ 1% cutoff). Conclusions: Single agent avelumab showed an acceptable safety profile and clinical activity in GC/GEJ pts. Objective responses and disease stabilization were observed in both groups. Median PFS was longer in PD-L1+ pts. Phase III trials in 1L and 3L GC/GEJ are underway.*Proposed INN Clinical trial information: NCT01772004.

Abstract Background The phase III JACOB trial (NCT01774786) compared the efficacy and safety of pertuzumab and trastuzumab plus chemotherapy with placebo and trastuzumab plus chemotherapy in patients with previously untreated human epidermal growth factor receptor 2 (HER2)-positive metastatic gastric or gastroesophageal junction cancer. We conducted a subgroup analysis in Japanese patients. Methods Patients were randomized 1:1 to pertuzumab 840 mg or placebo, plus trastuzumab (loading dose, 8 mg/kg; maintenance dose, 6 mg/kg) and chemotherapy (cisplatin 80 mg/m2, and capecitabine 1000 mg/m2 twice daily for 28 doses or 5-fluorouracil 800 mg/m2 every 24 h for 120 h), every 3 weeks. Continuation of chemotherapy after 6 cycles was at the discretion of the patient and the treating physician. Results A total of 40 Japanese patients were included in each arm. Median overall survival was 22.0 months (95% confidence interval [CI] 13.8–not evaluable) and 15.6 months (95% CI 9.7–19.2) in the pertuzumab and placebo arms, respectively (hazard ratio [HR] 0.64 [95% CI 0.37–1.10]). Median progression-free survival was 12.4 months (95% CI 6.1–14.1) in the pertuzumab arm and 6.3 months (95% CI 4.3–8.1) in the placebo arm (HR 0.50 [95% CI 0.30–0.82]). Grade ≥ 3 adverse events and serious adverse events were more frequent in the pertuzumab arm than the placebo arm. Conclusions Results from this subgroup analysis of the JACOB trial suggest similar efficacy of pertuzumab in Japanese patients and patients in the overall population, encouraging continued investigation of new agents for gastric cancer in Japanese patients.

Abstract Background: A previous single-arm Phase 2 study (Nature Med5:1171–7,1999), evaluated the ability of tumor-specific idiotype (ID) conjugated to keyhole limpet hemocyanin (KLH) administered with granulocyte-monocyte colony-stimulating factor - GM-CSF (BiovaxID vaccine) to induce complete remission (CR) and molecular remission (MR) in follicular NHL patients in first CR after chemotherapy. We reported (ASH 2005, Abstr 2441) that at 9.2 years follow-up, disease free survival (DFS) and overall survival (OS) were 45% and 95%, respectively; median DFS was 8.0 years. To date, there have been no additional reported mortalities in this cohort. Although these data are promising, improvements in the treatments and increasing survival for patients with follicular lymphoma have necessitated additional rigor in the evaluation of overall safety and overall risk-benefit. The ongoing Phase 3 study that opened in 2000 by the NCI is designed to evaluate the impact of this vaccine on DFS in previously untreated subjects who have attained CR/Cru. As of August 2007, 231 subjects have been enrolled to receive chemotherapy and 176 have been randomized to receive vaccine (ID-KLH or KLH-KLH). Methods: Since Phase 3 trial inception in 2000, SAEs have been reported through a pharmacoviligance group and identified according to time period on the study (i.e. during chemotherapy, during vaccine, after vaccine, or unknown), causality, and relatedness to study agent. Results: As of August 2007, 32 SAEs have been reported in the BV301 trial, 7 of which occurred during the vaccination segment of the study. At a blinded interim analysis of the Phase 3 safety data, of the 7 SAEs reported during the vaccine segment of the study, 3 are considered unlikely to be related to the study agent (chest pain, compression fracture, herpes zoster), 2 possibly related (arrhythmia supraventricular, chest pain), 1 unrelated (vomiting), and 1 unknown (febrile neutropenia). The 1 SAE, cerebral ischaemia, that occurred post vaccine is considered unrelated to the study agent. Conclusions: Additional follow-up on the Phase 2 patients is needed, as well as similar analyses in other cohorts. Blinded Phase 3 safety data shows a positive safety profile for BiovaxID. Unblinded safety data will be needed to determine the final efficacy and safety profile.

Duration Of Response

4503 Background: KEYNOTE-061 ( NCT02370498) is a global phase 3 study of pembrolizumab vs paclitaxel as second-line therapy for GC. At the time of primary analysis (data cutoff: Oct 26, 2017), in patients with PD-L1–positive status (combined positive score [CPS] ≥1), pembrolizumab did not significantly prolong overall survival (OS) vs paclitaxel (9.1 months vs 8.3 months) but did elicit a longer duration of response (DOR) and a favorable safety profile vs paclitaxel. We present results of KEYNOTE-061 in patients with CPS ≥1, ≥5, and ≥10 after 2 additional years of follow-up (cutoff: Oct 7, 2019). Methods: Adult patients with GC that progressed after platinum + fluoropyrimidine chemotherapy were randomly assigned 1:1 to pembrolizumab 200 mg Q3W for up to 35 cycles (~2 y) or standard-dose paclitaxel. OS and progression-free survival (PFS) in the CPS ≥1 population were the primary end points. Comparisons were made using stratified log-rank tests. Results: At the time of this analysis, 366/395 patients with CPS ≥1 had died (92.6%). Pembrolizumab prolonged OS vs paclitaxel in PD-L1–positive patients (Table). No significant differences appeared between groups in PFS (Table). Objective response rate (ORR) was higher for pembrolizumab in the CPS ≥10 group, and DOR was longer with pembrolizumab using all CPS cutoffs (Table). There were fewer drug-related adverse events (AEs) with pembrolizumab than paclitaxel in the overall population (53% vs 84%). Conclusions: This long-term analysis found that second-line pembrolizumab prolonged OS among patients with PD-L1–positive GC and led to fewer drug-related AEs vs paclitaxel.

Abstract CPX-351, a dual-drug liposomal encapsulation of daunorubicin/cytarabine in a synergistic 1:5 molar ratio, is approved for the treatment of adults with newly diagnosed, therapy-related acute myeloid leukemia (t-AML) or AML with myelodysplasia-related changes (AML-MRC). In a pivotal phase 3 study, patients aged 60 to 75 years with newly diagnosed, high-risk/secondary AML were randomized to receive CPX-351 or conventional 7+3 chemotherapy. In the primary endpoint analysis, CPX-351 demonstrated significantly prolonged median overall survival (OS) vs 7+3. These exploratory post hoc subgroup analyses evaluated the impact of achieving complete remission (CR) or CR with incomplete neutrophil or platelet recovery (CRi) with CPX-351 (73/153 [48%]) vs conventional 7+3 (52/56 [33%]) on outcomes. CPX-351 improved median OS vs 7+3 in patients who achieved CR or CRi (25.43 vs 10.41 months; hazard ratio = 0.49; 95% confidence interval, 0.31, 0.77). Improved median OS was seen across AML subtypes (t-AML, AML-MRC), age subgroups (60 to 69 vs 70 to 75 years), patients with prior hypomethylating agent exposure, and patients who did not undergo transplantation. Patients who achieved CR or CRi with CPX-351 also had a higher rate of transplantation, a longer median OS landmarked from the date of transplantation (not reached vs 11.65 months; hazard ratio = 0.43; 95% confidence interval, 0.21, 0.89), and a safety profile that was consistent with the known safety profile of 7+3. These results suggest deeper remissions may be achieved with CPX-351, leading to improved OS. This study was registered at www.clinicaltrials.gov as #NCT01696084.
