8028 Background: K-based regimens improved progression-free survival (PFS) and overall survival (OS) in RRMM patients (pts) in ASPIRE (K [27 mg/m2]-lenalidomide-dexamethasone [KRd] vs Rd) and ENDEAVOR (K [56 mg/m2]-dexamethasone [Kd56] vs bortezomib-dexamethasone [Vd]), regardless of age. Frailty scores have been developed based on age, comorbidities, and functional status (Palumbo Blood 2015;125:2068–74; Facon Blood 2015;126:4239). We assessed post hoc pt outcomes by frailty status. Methods: PFS, OS, and safety were assessed by treatment arm and frailty score (based on age, medical history-derived Charlson Comorbidity Index, and ECOG performance status); frailty scores: 0 = fit, 1 = intermediate (int), and ≥2 = frail. Results: Pt frailty status was balanced between treatment arms in ASPIRE and ENDEAVOR. Median PFS and OS were longer with K-based regimens vs controls in ASPIRE and ENDEAVOR across frailty subgroups (Table). Rates of treatment-emergent adverse events are summarized in the Table. Conclusions: Kd56 and KRd consistently improved outcomes vs Vd and Rd, respectively, in all frailty subgroups as defined by the algorithm above. These findings support the favorable benefit-risk profile of KRd and Kd56 regardless of frailty score. Clinical trial information: NCT01080391 and NCT01568866. [Table: see text]

8027 Background: A.R.R.O.W. demonstrated superior progression-free survival (PFS) with once-weekly K (70 mg/m2)-dexamethasone (Kd70) vs twice-weekly K (27 mg/m2)-dexamethasone (Kd27) in relapsed and refractory multiple myeloma (RRMM) pts, regardless of age. Weekly Kd70 is US-approved for relapsed or refractory MM (1–3 prior therapy lines). For a comprehensive fitness measure, frailty scales were developed incorporating age, comorbidities, and functional status. (Palumbo Blood 2015; Facon Blood 2015). Here we assessed post hoc pt outcomes by frailty status. Methods: PFS and safety were assessed by treatment arm and a frailty algorithm incorporating age, medical history–derived Charlson Comorbidity Index, and ECOG performance status; pts with frailty scores of 0, 1, or ≥2 were classified as fit, intermediate (int), or frail, respectively. PFS was assessed with the Kaplan-Meier method. Safety was assessed in pts who received ≥1 treatment dose. Results: Pt distribution by frailty status was generally balanced between arms (Table). Once-weekly Kd70 vs twice-weekly Kd27 resulted in median PFS for fit, int, and frail pts of 15.7 vs 5.7 (mos; HR 0.53 [95% CI, 0.33–0.86]), 11.1 vs 7.7 mos (HR 0.81 [95% CI, 0.55–1.19]), and 10.3 vs 6.6 mos (HR 0.76 [95% CI, 0.49–1.16]), respectively. Rates of grade ≥3 treatment-emergent adverse events (TEAEs) of interest were similar between treatment arms across frailty subgroups (Table). In the once-weekly Kd70 subgroups, there was no grade ≥3 peripheral neuropathy (PN); grade ≥3 cardiac failure rates were ≤4%. Conclusions: Once-weekly Kd70 resulted in PFS benefits vs twice-weekly Kd27 with a favorable benefit/risk profile regardless of frailty score as defined. These results support weekly Kd70 as a treatment option for both fit and frail RRMM pts. Clinical trial information: NCT02412878. [Table: see text]

469 Background: The phase III VELOUR study demonstrated that adding the novel antiangiogenic agent aflibercept (known as ziv-aflibercept in the United States) to FOLFIRI in patients with metastatic colorectal cancer previously treated with oxaliplatin significantly improved overall survival, progression-free survival (PFS), and overall response rate versus placebo-FOLFIRI. We performed an additional analysis of PFS “on-treatment,” censoring events that occurred more than 28 days after last treatment dose. Methods: Patients were randomized to receive aflibercept 4 mg/kg or placebo every 2 weeks in combination with FOLFIRI. An independent review committee determined progression based on radiologic review. PFS was estimated using Kaplan-Meier analysis, with censoring of events after the last dose plus 28 days. Treatment groups were compared using a log-rank test stratified by ECOG performance status and prior bevacizumab therapy. Hazard ratio (HR) and confidence interval (CI) were estimated using a Cox proportional hazard model. Results: On-treatment PFS results are shown in the Table. Patients on aflibercept-FOLFIRI showed significantly increased on-treatment PFS compared with patients on placebo-FOLFIRI. More patients were censored in the aflibercept arm due to adverse events, thus decreasing the number of events. Conclusions: On-treatment PFS with aflibercept-FOLFIRI was significantly increased compared with placebo-FOLFIRI, which is consistent with the PFS benefit observed in the primary analysis.

Prognostic And Predictive Markers

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice. Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.

Purpose To test the efficacy of adding cisplatin to first-line treatment for elderly patients with advanced non–small-cell lung cancer (NSCLC) within a combined analysis of two parallel phase III trials, MILES-3 and MILES-4. Patients and Methods Patients with advanced NSCLC who were older than age 70 years with Eastern Cooperative Oncology Group performance status 0 to 1 were randomly assigned to gemcitabine or pemetrexed, without or with cisplatin. In each trial, 382 events were required to detect a hazard ratio (HR) of death of 0.75, with 80% power and two-tailed α of .05. Trials were closed prematurely because of slow accrual, but the joint database allowed us to analyze the efficacy of cisplatin on the basis of intention-to-treat and adjusted by trial, histotype, non-platinum companion drug, stage, performance status, sex, age, and size of the study center. Results From March 2011 to August 2016, 531 patients (MILES-3, 299; MILES-4, 232) were assigned to gemcitabine or pemetrexed without (n = 268) or with cisplatin (n = 263). Median age was 75 years, 79% were male, and 70% had nonsquamous histology. At a median 2-year follow-up, 384 deaths and 448 progression-free survival events were recorded. Overall survival was not significantly prolonged with cisplatin (HR, 0.86; 95% CI, 0.70 to 1.05; P = .14) and global health status score of quality of life was not improved, whereas progression-free survival (HR, 0.76; 95% CI, 0.63 to 0.92; P = .005) and objective response rate (15.5% v 8.5%; P = .02) were significantly better. Significantly more severe hematologic toxicity, fatigue, and anorexia were found with cisplatin. Conclusion The addition of cisplatin to single-agent chemotherapy does not significantly prolong overall survival, and it does not improve global health status score of quality of life in elderly patients with advanced NSCLC.

The Impact

4601 Background: A phase I/II study with GV1001, a telomerase peptide vaccine, showed a median overall survival (OS) of 8.6 months in non-resectable PC (Bernhardt SL et al, Br J Cancer. 2006;95:1474–1482). This phase III trial was conducted to determine the impact on overall survival of G monotherapy vs. GV1001 in sequential combination with G in unresectable and metastatic PC. Methods: Eligible patients (pts) had chemotherapy-naive, advanced PC and ECOG performance status 0–1. Pts were randomized 1:1 to receive arm A: G (1,000 mg/m2 30 min i.v.) weekly for 7 weeks (w), 1w off and then 3w during 4-weekly cycles, or arm B: GV1001 0.56 mg s.c. plus GM-CSF as immune adjuvant on days 1, 3, 5, 8, 15, 22, 36, then every 4 weeks. Patients who progressed clinically or radiologically during GV1001 continued on GV1001 and concomitant gemcitabine. CT scans were performed every 8 weeks. The primary end-point was OS. A sample size of 520 patients allowed the detection of a hazard ratio (HR) of 0.73 (B/A), with 2α = 0.05 and 90% power. Results: Between June 2006 and May 2008, 365 pts were enrolled (A / B; 182 / 183). The study was stopped prematurely due to a preliminary analysis with 178 events showing no survival benefit of GV1001. Pts were well balanced for baseline characteristics: male 59.3% / 62.8%; median age 61y / 61y; ECOG PS 0 34.3% / 36.7%; locally advanced 22.4% / 20.7%. As of August 2008, 238 pts (A / B : 114 / 124) had died. Median OS was 7.3 / 5.9 months (HR 0.8; 95% CI 0.6–1.0). Median progression-free survival (PFS) was 3.7 / 1.9 months (HR 0.5; 95%CI 0.4–0.7). Grade 3–4 AEs: gastrointestinal 6% / 8%, infection 5% / 5%, vascular disorders 2% / 3%, neutropenia 6% / 3%. Conclusions: GV1001 did not show efficacy in sequential combination with G in advanced PC. The advantage of G monotherapy over the sequential combination may be due to the delayed treatment with G in arm B. [Table: see text]

7565 Background: Standard first-line chemotherapy for elderly NSCLC pts has been considered as a monotherapy with vinorelbine or gemcitabine globally. However, we have demonstrated the high efficacy of CP for elderly pts in our previous trial (Ann Oncol 2010). Meanwhile, D has been considered as an alternative option for this population in Japan according to the result of WJTOG9904 (JCO 2006). Thus we compared the two regimens to select the proper candidate for future phase III trial. Methods: Eligible pts were aged 70 years or older with newly diagnosed stage IIIB/IV NSCLC; ECOG performance status 0-1; adequate organ function; written informed consent. Pts were randomized to receive carboplatin (AUC 6) on day 1 and paclitaxel (70mg/m2 on day 1, 8, and 15) every 4 weeks or D (60mg/m2 on day 1) every 3 weeks. The primary endpoint was overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival, and toxicity profile. Assuming that ORR of 40% would be potential usefulness while ORR of 20% would be the lower limit of interest, 40 pts in each arm were required if expect 10% loss to follow up. Results: Between July 2006 and September 2010, 84 pts were enrolled and 41 pts in CP arm and 42 pts in D arm were eligible (median age, 76 years; 75% male; 72% stage IV). Median treatment cycle was 4 in each arm (CP, range 1-6; D, range 1-8). ORRs were 51% (95%CI: 36-66%) and 26% (95%CI: 12-39%) in the CP and D arm, respectively. With a median follow-up of 18.4 months, median PFS were 6.5 and 3.9 months in the CP and D arm, respectively (Logrank, P=0.0027). Grade 3 or severer toxicities were as follows: neutropenia (CP, 56% and D, 79%), anemia (CP, 15% and D, 7%), thrombocytopenia (CP, 10% and D, 0%), infection (CP, 20% and D, 25%). One treatment-related death due to neutropenia, pneumonia, and lethal arrhythmia occurred in D arm but none in CP arm. Conclusions: The platinum doublet CP achieved higher activity with an acceptable toxicity profile for elderly pts with advanced NSCLC compared to monotherapy with D. The superiority of CP to the monotherapy in this trial is consistent with results of recent IFCT-0501 trial (Lancet 2011).

LBA10008 Background: Oral multikinase inhibitor regorafenib (REG) demonstrated substantial activity in a phase II trial in pts with GIST after failure of both IM and SU (J Clin Oncol. 2011; 29:606s; abstr 10007). This phase III, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of REG for this unmet clinical need. Methods: Eligible pts had metastatic and/or unresectable GIST, objective failure of both prior IM and SU (progressive disease [PD] on, or intolerance to, IM and PD on SU), ≥1 measurable lesion, ECOG performance status 0 or 1. Pts were randomized 2:1 to receive best supportive care plus either REG 160 mg po once daily (3 wks on/1 wk off) or placebo (PL). The primary endpoint was progression-free survival (PFS) (modified RECIST 1.1, independent central review). Secondary endpoints included overall survival (OS), disease control rate (DCR, defined as rate of partial response [PR] plus stable disease [SD] lasting for ≥12 wks), response rate and duration, safety and correlative genotype analyses. At time of PD, pts were eligible for unblinding and crossover to open-label REG. Results: Between Jan and Aug of 2011, 234 pts were screened; 199 were randomized (REG: 133, PL: 66). Pts were stratified at randomization according to number of prior systemic therapies and geographical region. Baseline characteristics were balanced between the two arms. The primary endpoint was met: median PFS was 4.8 months for REG vs. 0.9 months for PL. Hazard ratio for PFS was 0.27 (95% CI, 0.18-0.39), p<0.0001. PFS rates at 3 and 6 months were 60% and 38% for REG vs. 11% and 0% for PL. DCR was 53% (REG) vs. 9% (PL).The HR for OS was 0.77 (p=0.20) with 85% PL pts having crossed over to REG. The most common > grade 3 treatment-emergent AEs in the REG arm during double-blind study were hypertension (28%), hand-foot skin reaction (21%), and diarrhea (8%). Conclusions: This randomized trial demonstrated that REG significantly improved PFS and DCR in pts with advanced GIST after failure of at least prior IM and SU. REG was well tolerated, with AEs as expected for this class and manageable with dose modifications.

9030 Background: Activating mutations of BRAF V600 can be found in 40%-50% of melanomas and are related to poor prognosis. In a phase 3 trial for the treatment of metastatic melanoma (MM) in chemotherapy-naive patients, nab-paclitaxel (nab-P) vs dacarbazine (DTIC) demonstrated a significant improvement in the primary endpoint of progression-free survival (PFS), assessed by independent radiological review (IRR), and a trend toward prolonged overall survival (OS) at the interim survival analysis. The study also explored the effect of BRAF status on the efficacy parameters. Methods: Chemotherapy-naive patients with stage IV melanoma (M1c stage 65%; elevated LDH 28%) and ECOG performance status 0-1 were randomized to nab-P 150 mg/m2 on days 1, 8, and 15 of a 28-day cycle (n = 264) or DTIC 1000 mg/m2 on day 1 of each 21-day cycle (n = 265) independent of BRAF status. Prespecified subgroup analyses of final PFS and interim OS in subgroups by BRAF status (V600E mutant, wild-type, or unknown) were performed. Results: BRAF mutation status was balanced between the treatment arms, with 36% and 38% of patients with known BRAF mutation status in the nab-P and DTIC arms, respectively. Patient characteristics were also balanced within BRAF subgroups. As shown in the Table, advantage in the nab-P arm vs DTIC arm was observed for both PFS and interim OS regardless of BRAFmutation status. Poststudy BRAF inhibitor treatment was also balanced. Conclusions: In this phase III trial, treatment effect was independent of BRAF mutation status, benefiting all patients who received nab-P vs DTIC. Therefore nab-P should be considered in the armamentarium for all chemotherapy-naive patients with MM. Clinical trial information: NCT00864253. [Table: see text]

e19022 Background: Progression-free survival (PFS) is a key trial end point for clinical practice, as it relates to a change of treatment line. Grade 4 progression-free survival (G4PFS; defined as time from treatment start to the earlier of progressive disease [PD], onset of a G4 adverse event [AE], or death from any cause) is a composite end point incorporating a measure of tolerability to PFS. This post hoc analysis evaluates G4PFS and the effect of G4 AEs on PFS and overall survival (OS) in patients (pts) enrolled in PointBreak (PB) and AVAiL. Methods: Pts in PB were randomized to bevacizumab (BEV) 15 mg/kg q3w with carboplatin and paclitaxel (CP) or pemetrexed (CPem) for ≤4 cycles. Eligible pts received either BEV or BEV + Pem q3w until PD or unacceptable toxicity. Pts in AVAiL received cisplatin and gemcitabine for ≤6 cycles and either placebo or BEV (7.5 or 15 mg/kg) q3w until PD. AEs were graded via NCI-CTCAE v3.0. Kaplan-Meier and Cox model methods were used to estimate medians and hazard ratios (HRs) for PFS, G4PFS, and OS. PFS and OS were also compared in each arm for pts with occurrence of a G4 AE before week 12 of treatment vs those without. Results: Of those receiving BEV, ~30% of AVAiL pts and 38% of PB pts had a G4 AE. Uncomplicated neutropenia was the most common G4 AE in the CP + BEV arm of PB (26%) and in the BEV arms of AVAiL (11%). PFS, G4PFS, and outcomes by G4 AE occurrence are shown (Table). Conclusions: In both the PB and AVAiL trials, median G4PFS was numerically shorter than median PFS. G4 AE occurrence, however, did not affect subsequent PFS or OS in either trial. Clinical trial information: NCT00762034 and NCT00806923. [Table: see text]

189 Background: The optimal treatment and outcome for elderly patients (pts) with localized gastroesophageal (GE) cancer remains unclear as they are underrepresented in clinical trials. We aimed to assess survival in pts ≥ 75 years according to treatment received. Methods: A retrospective analysis was performed for all pts aged ≥ 75 years with GE cancer treated in 2012 and 2013. Frailty was measured using the Charlson comorbidity index (CCI) and ECOG performance status (PS). Overall survival (OS) and disease-free survival (DFS) were assessed via uni- and multivariable Cox proportional hazards regression, adjusting for demographics. Logistic regression analyses were used to examine factors impacting treatment choices. Results: Of 70 pts, median age was 82 years (range: 75-98), primary sites were esophageal (40%, with 61% squamous histology), GE junction (24%) and gastric (36%). Baseline characteristics included: PS: 0 (40%), 1 (39%), 2 (14%), 3 (7%); and CCI: 0 (36%), 1 (20%), 2 (21%), ≥ 3 (23%). Treatment received included surgery (33%), radiotherapy (RT) (31%); surgery plus adjuvant chemotherapy (chemo) and/or RT (9%); chemoradiation alone (7%) and 20% had no active treatment. In univariable analysis; age < 85 (p = 0.007) and surgery (p = 0.022) were associated with improved OS. Chemo and RT, either alone or in combination, did not significantly improve OS. In multivariable analysis; age < 85 (HR 0.46, 95% CI: 0.23-0.94, p = 0.034), surgery (HR 0.32, 95% CI: 0.14-0.74, p = 0.008) and CCI < 2 (HR 0.52, 95% CI: 0.27-0.99, p = 0.048) were identified as independent predictors for improved OS. Age ≥ 85 was significantly associated with omission of surgery (OR 3.61, 95% CI: 1.13-14.01, p = 0.041) but in contrast, PS ≥ 2 (p = 0.475) and CCI ≥ 2 (p = 0.939) were not predictive. Conclusions: At our institution, very few pts ≥ 75 years received multimodality therapy for localized GE cancers. Surgery was the only treatment modality associated with a significant survival advantage, and additional chemo and/or RT did not further improve OS. The only predictor for having surgery was age. Consequently, future studies should consider comprehensive assessment for surgery so that eligible elderly pts can benefit.
