8014 Background: Maintenance monotherapy has been associated with improved survival for NSCLC pts. AVAPERL was designed to evaluate the safety and efficacy of bevacizumab with or without pemetrexed as continuation maintenance treatment and demonstrated improved progression-free survival (PFS) (Barlesi, JCO in press). Methods: Pts with advanced nsNSCLC received first-line Bev (7.5 mg/kg), cisplatin (75 mg/m2), and Pem (500 mg/m2) every 3 weeks (q3w) for 4 cycles. Those non progressing were randomized to maintenance Bev (7.5 mg/kg) +/-Pem (500 mg/m2) q3w until progressive disease or unacceptable toxicity. The primary end point (PFS) was met. An independent update analysis has been conducted to assess OS. Results: A total of 376 pts receive induction treatment; 125 and 128 were randomized to the Bev-alone and Bev+Pem arms, respectively. Induction therapy resulted in confirmed disease control in 71.9% of pts. After a median follow-up of 14.8 months, PFS for the Bev+Pem arm was significantly improved both from induction (10.2 v 6.6 m, HR 0.58 [0.45-0.76], p<.0001) and randomization (7.4 v 3.7 m, HR 0.57 [0.44-0.75], p<.0001). With 58% of events, OS for the Bev+Pem arm was also improved both from induction (19.8 v 15.9 m, HR 0.88 [0.64-1.22], p=.32) and randomization (17.1 v 13.2 m, HR 0.87 [0.63-1.21], p=.29). The PFS and OS improvements were comparable across age, PS, smoking status, and response to induction (SD vPR/CR) subgroups. No new safety signal was observed during this updated analysis. Conclusions: Continuation maintenance with Bev+Pem in an unselected population of nsNSCLC pts who had achieved disease control after induction was associated with an increase by almost 4 months in OS benefit over standard Bev alone. Clinical trial information: NCT00961415.

3575 Background: The literature reports that adding biologics to chemotherapy (ctx) may increase the incidence of clinically significant neutropenia. his trial was conducted to evaluate the efficacy of PEG in reducing the incidence of febrile neutropenia (FN) in pts with locally-advanced (LA) or metastatic (m)CRC receiving first-line treatment with either FOLFOX/B or FOLFIRI/B. Methods: Key eligibility: ≥ 18 years old; measurable, nonresectable CRC per RECIST 1.1. Pts were randomly assigned 1:1 to either placebo or 6 mg PEG ~24 h after ctx/B. The study treatment period included four Q2W cycles, but pts could continue their assigned regimen until progression. Pts were stratified by region (North America vs rest of world), stage (LA vs mCRC), and ctx (FOLFOX vs FOLFIRI). Estimated sample size (N = 800) was based on the expected incidence of grade 3/4 FN (primary endpoint) across the first 4 cycles of ctx/B, powered for PEG superiority over placebo. Other endpoints included overall response rate (ORR), progression-free survival (PFS), and overall survival (OS). Results: 845 pts were randomized (Nov 2009 to Jan 2012) and received study treatment; 783 pts completed 4 cycles of ctx/B. Median age was 61 years; 512 (61%) pts were male; 819 (97%) had mCRC; 414 (49%) received FOLFOX, and 431 (51%) received FOLFIRI. Grade 3/4 FN (first 4 cycles) for placebo vs PEG was 5.7% vs 2.4%; OR 0.41; p = 0.014. A similar incidence of other ≥ grade 3 adverse events was seen in both arms (28% placebo; 27% PEG). See table for additional results. Conclusions: PEG significantly reduced the incidence of grade 3/4 FN in this pt population receiving standard ctx/B for CRC. Follow-up is ongoing. Clinical trial information: NCT00911170. [Table: see text]

8032 Background: The impact of t(11;14) (16%–24% of MM pts) on prognosis is not fully understood. Consensus is lacking on the effects of induction treatment (tx) on outcomes with t(11;14). The Connect MM Registry (NCT01081028) is a large, US, multicenter, prospective observational cohort study of pts with NDMM designed to examine real-world diagnostic patterns, treatment (tx) patterns, clinical outcomes, and HRQoL pt-reported outcomes in pts with NDMM. The impact of t(11;14) on tx outcomes are reported. Methods: Analysis included data from pts from 250 community, academic, and government sites in cohort (C) 1 (9/2009–12/2011) and C2 (12/2012–4/2016), who completed first-line (1L; induction) tx and were tested for t(11;14) by FISH or cytogenetics. Primary end points (progression-free survival [PFS] and overall survival [OS]) were measured from start of 1L tx to earliest event (PFS, death or progression; OS, death), loss to follow-up, or data cutoff, adjusted for baseline (BL) risk factors. A sensitivity analysis excluding pts with concomitant cytogenetic abnormalities [del 17p, t(4;14), t(14;16), 1q+] was also performed. Results: By 1/2018, 3011 pts were enrolled; 2938 were treated. Of 1574 enrolled pts tested for t(11;14), 378 were t(11;14)+ and 1196 were t(11;14)−. More pts in C2 vs C1 were t(11;14)+ (60% vs 40%). BL characteristics were similar between groups. t(11;14) status did not affect PFS ( P= NS) or OS ( P= NS; Table). Pts in C1 and C2 received similar 1L txs (IMiD agent + proteasome inhibitor [PI], 30% vs 42%; PI only, 42% vs 43%; IMiD agent only, 17% vs 11%). Results were similar when pts with concomitant abnormalities were excluded. Conclusions: Results of this analysis suggest that t(11;14) does not affect PFS and OS outcomes in NDMM pts. Clinical trial information: NCT01081028. [Table: see text]

Abstract Purpose: Alemtuzumab (MabCampath) is a humanized monoclonal antibody that targets the CD52 antigen, which is highly expressed on most human B and T lymphocytes. Alemtuzumab has shown considerable activity in both relapsed/refractory CLL and in the frontline treatment setting. In a recent study, treatment with single-agent alemtuzumab induced MRD-negative remissions in 20% of patients with relapsed/refractory CLL (Moreton et al JCO 2005;23:2971–2979). Other studies suggest that MRD negativity can also be attained when alemtuzumab is administered as consolidation for patients with CLL who achieve incomplete initial responses to chemotherapy. Here, we report our long-term experience within a randomized phase III trial that investigates the role of alemtuzumab for consolidation therapy in patients with previously untreated CLL. Methods: Pts in complete or partial remission after induction chemotherapy, with either fludarabine (F) or fludarabine plus cyclophosphamide (FC), were randomized to receive either alemtuzumab 30 mg, 3 times a week for ≤12 wks or no further treatment. Of 21 eligible pts, who had responded to induction with F or FC (1 CR, 1 nPR, 9 PRs), 11 pts (median age: 60 years) randomized to receive alemtuzumab consolidation and 10 to the observation arm. Pts in the alemtuzumab arm received standard premedication and infection prophylaxis with famciclovir and trimethoprim/sulfamethoxazole. Results: After a median follow-up of 48 months, calculated from time of randomization within this consolidation trial, progression-free survival (PFS) was significantly improved for pts who received alemtuzumab consolidation compared to those who received no further treatment (median PFS not reached versus 20.6 months, P = 0.004). PFS from the beginning of induction therapy with F or FC is also significantly greater for patients in the alemtuzumab consolidation arm versus the observation arm. So far, 3 of 11 pts presented with disease progression after alemtuzumab consolidation compared with 8/10 progressing pts in the observation arm. Differences in PFS between both arms were not associated with disease stage before first line treatment, type of first line chemotherapy (F vs. FC) or response status before initiation of consolidation therapy (CR vs. nPR vs. PR). Correlations between achievement of MRD negative responses and PFS is still under investigation and is planned for presentation. With the exception of 2 patients (1 pt in each arm) all patients remain alive. The study was stopped prematurely due to severe infections (7 CTC III infections, which included 4 CMV reactivations, 1 CTC IV infection) in 7/11 patients being treated with alemtuzumab. However, these infections were successfully treated, not associated with the cumulative dose of alemtuzumab, and no late complications of consolidation therapy have been observed. Conclusions: Although based on few pts due to incomplete accrual, long-term PFS was significantly prolonged in patients with CLL receiving alemtuzumab consolidation after first line chemotherapy with F or FC. An ongoing phase I/II trial of the GCLLSG (CLL2i) is currently evaluating the optimal dose and schedule of alemtuzumab in CLL pts after fludarabine-based chemotherapy.

3615 Background: Retrospective data suggested that the continuation of BV with second-line CT beyond progression (PD) in pts who received BV in first-line can improve the outcome. Recently, results of the AIO/AMG ML18147 study demonstrated an improved overall survival (OS) by continuing BV beyond PD. Methods: This phase III study randomized pts with measurable mCRC treated in first-line with BV plus fluoropyrimidine, FOLFIRI, FOLFOX or FOLFOXIRI, to receive in second-line mFOLFOX6 or FOLFIRI (depending on first-line CT) with or without BV. The primary end-point was progression free survival (PFS).To detect a HR for PFS of 0.70 with an α and β error of 0.05 and 0.20 respectively, the study required 249 events. Assuming an accrual time of 24 months (mos) and a follow up of 12 mos we planned to randomize 262 pts. Results: Considering the results of the AIO/AMG ML18147 trial, the study accrual was stopped prematurely. A total of 185 pts were randomized and 184 pts were included in the ITT analysis (1 pt randomized in error). Pts characteristics were (arm A/arm B): number 92/92, gender M75%-F25%/M57%-F43%, median age 66 (38-75)/62 (38-75) years, PS=0 82%/82%, multiple site of disease 76%/77%. At a median follow up of 18 mos the study met its primary endpoint by improving PFS in the BV arm. We updated results and at a median follow up of 22 mos the improvement in PFS for the experimental arm was confirmed with a median PFS of 5.2 mos for arm A and 6.7 mos for arm B (HR=0.66; 95% CI 0.49–0.90; unstratified p=0.0072). Subgroup analyses showed a consistent benefit in all subgroups including gender (F: HR=0.63; M: HR=0.72) and first-line PFS (≤10 mos: HR=0.57; >10 mos: HR=0.71). Response rates (RECIST) were 18% and 21% (p=0.71). Toxicity profile was consistent with previously reported data. The OS data are still immature, with 56 events in arm A and 54 in arm B and the median OS is 16.0 mos and 16.5 mos respectively (HR=0.83; 95% CI 0.57-1.22; unstratified p=0.34). Conclusions: This study demonstrates an improvement in PFS by continuing BV in second-line in pts who had received CT+BV in first-line. Clinical trial information: NCT00720512.

PurposeUpdated results are presented after a median follow-up of 7.3 years from the phase III First-Line Indolent Trial of yttrium-90 (90Y) –ibritumomab tiuxetan in advanced-stage follicular lymphoma (FL) in first remission.Patients and MethodsPatients with CD20+stage III or IV FL with complete response (CR), unconfirmed CR (CRu), or partial response (PR) after first-line induction treatment were randomly assigned to90Y-ibritumomab consolidation therapy (rituximab 250 mg/m2days −7 and 0, then90Y-ibritumomab 14.8 MBq/kg day 0; maximum 1,184 MBq) or no further treatment (control). Primary end point was progression-free survival (PFS) from date of random assignment.ResultsFor 409 patients available for analysis (90Y-ibritumomab, n = 207; control, n = 202), estimated 8-year overall PFS was 41% with90Y-ibritumomab versus 22% for control (hazard ratio [HR], 0.47; P < .001). For patients in CR/CRu after induction, 8-year PFS with90Y-ibritumomab was 48% versus 32% for control (HR, 0.61; P = .008), and for PR patients, it was 33% versus 10% (HR, 0.38; P < .001). For90Y-ibritumomab consolidation, median PFS was 4.1 years (v 1.1 years for control; P < .001). Median time to next treatment (TTNT) was 8.1 years for90Y-ibritumomab versus 3.0 years for control (P < .001) with approximately 80% response rates to second-line therapy in either arm, including autologous stem-cell transplantation. No unexpected toxicities emerged during long-term follow-up. Estimated between-group 8-year overall survival rates were similar. Annualized incidence rate of myelodysplastic syndrome/acute myeloblastic leukemia was 0.50% versus 0.07% in90Y-ibritumomab and control groups, respectively (P = .042).Conclusion90Y-ibritumomab consolidation after achieving PR or CR/CRu to induction confers 3-year benefit in median PFS with durable 19% PFS advantage at 8 years and improves TTNT by 5.1 years for patients with advanced FL.

4072 Background: In a phase III pivotal trial in patients (pts) with metastatic colorectal cancer (mCRC), BEV (BEV, Avastin®) increased overall survival (OS) by 30% when added to first-line IFL chemotherapy (CT). Recently, a second trial reported a significant improvement in progression free survival (PFS) when BEV was added to FOLFOX/XELOX in a similar patient population. Although, First BEAT was opened to evaluate the safety profile of BEV in a broader pt population using a variety of CT regimens, efficacy endpoints were investigated. Methods: First BEAT enrolled 1,927 mCRC patients in 41 countries between June 2004 and February 2006. Eligible pts were treated with first-line CT (physician’s choice) in combination with BEV (5mg/kg q2w [5-FU-based CT] or 7.5mg/kg q3w [capecitabine [cap, Xeloda®]-based CT]) until disease progression. Secondary endpoints included OS, time to progression (TTP) and PFS. Disease progression was assessed by investigators. Results: By Nov 15th, 2006, 1,914/1,927 pts had data available for analysis (male 58%; median age 59 years, 33% =65 years; ECOG PS 0/1 65%/34%). Median follow-up was 15 months; 60-day mortality was 2.5%. Patients receiving 5-FU/cap CT appeared to have poorer prognosis with respect to age =65 years (41%), ECOG PS 0/1 (58%/42%) and 60-day mortality rate (6.6%), compared with those receiving doublet CT regimens. The most common first-line CT regimens used with BEV were FOLFOX (28%), FOLFIRI (26%), XELOX (18%) and 5-FU or cap CT (16%). Median PFS was 10.4 (95% CI: 10.1–10.9 months, based on 882 events), 10.5 (9.7 - 11.6) in FOLFOX, 10.3 (9.7 - 10.7) in XELOX, 11.1 (10.2–12.0) in FOLFIRI and 9.1 (8.1–10.3) in pts receiving 5-FU or cap CT, respectively. TTP was 10.8 (95% CI: 10.4–11.3 months, based on 805 events). Updated analyses will be presented. Conclusions: In this ongoing, large community-based study, the preliminary efficacy of first line BEV in mCRC pts receiving a variety of CT regimens appears consistent with that observed in large phase III randomised trials.

Abstract Abstract 1788 The GELA-sponsored intergroup PRIMA Phase III study was designed to investigate the potential benefit of 2-years of rituximab maintenance in high tumour burden follicular lymphoma patients responding to one of three non-randomised first line immunochemotherapy treatments. The results of the pre-planned interim analysis with 24 months median follow-up were positive and demonstrated a significant reduction in the risk of progression for patients randomized to rituximab maintenance (Salles et al., ASCO 2010). We present here the updated efficacy and safety results after an additional year of follow-up, when all randomized patients had completed the observation/maintenance period. From December 2004 until April 2007, 1217 patients were enrolled from 223 centres. Complete data are available for 1193 patients who had the following pre-induction treatment characteristics: median age 56 years [range 22–87]; 52% male; 90% Ann Arbor stage III-IV; 33% B symptoms; 55% bone marrow involvement; 4% ECOG performance status >1; 34% elevated LDH; 32% β2-microglobulin≥3mg/L; FLIPI score 0–1 (21%), FLIPI 2 (36%), FLIPI 3–5 (43%). Most patients (74%) received R-CHOP induction (22% R-CVP, 4% R-FCM). Patients responding to induction therapy were stratified based on their immunochemotherapy regimen and response [CR/CRu versus PR], and randomized to observation or rituximab maintenance, 1 infusion (375 mg/m2) every 8 weeks for 2 years. A total of 1018 randomised patients were analyzed according to the ITT principle (513 observation/505 rituximab maintenance). All initial pre-treatment characteristics were well balanced between arms and the response status at time of randomization was CR=39%; CRu=31% and PR=29% (others 1%). After a median follow-up of 36 months, 3-year progression free survival was 60.3% (95% confidence interval [CI] 55.8 – 64.5%) in the observation arm and 78.6% (95% CI 74.7 – 82%) in the rituximab maintenance arm, respectively (stratified Log-Rank, P<.0001; hazard ratio [HR]=0.55, 95% CI 0.44 – 0.68). In pre-planned analyses of patient subgroups categorized by age, sex, FLIPI score, induction chemotherapy and response to induction, the effect of rituximab maintenance was found to be consistent with the overall study results. In a Cox regression multivariate analysis, older age (P=.0013), male sex (P=.013), higher FLIPI group (P<.0001), R-CVP induction treatment (P=.003) and rituximab maintenance (P<.0001) were all significant variables associated with inferior progression free survival. A significant reduction in the number of patients starting a new anti-lymphoma treatment (HR=0.60, 95% CI 0.47 – 0.76) or starting a new chemotherapy (HR=0.62, 95% CI 0.47 – 0.81) was also observed for rituximab maintenance. Regarding response to treatment, 52% of the patients that were in PR at the time of randomization converted to CR or CRu at the end of 2-year maintenance in the rituximab maintenance arm compared to 30% of patients in the observation arm (P=.0001). As a result, 361 out of 482 patients evaluated (75%) in the rituximab maintenance arm were in CR or CRu as compared to 268 out of 491 patients evaluated (55%) in the observation arm (P< .0001). At the time of the data cut-off, 30 patients (6%) had died in the observation arm compared to 26 patients (5%) in the rituximab maintenance arm (HR=0.87, 95% CI 0.51 – 1.47). The most common adverse events reported were infections, which occurred in 24% and 39% of the patients in the observation and rituximab maintenance arms respectively. Grade 3–4 adverse events were reported in 17% of patients in the observation arm and 24% in the rituximab maintenance arm (neutropenia 1% vs 4%; infections 1% vs 4%, respectively) but these lead to treatment discontinuation in only 8 and 19 patients, respectively. In conclusion, after an additional year of follow-up, these data demonstrate a sustained benefit of 2 years of rituximab maintenance therapy after immunochemotherapy, resulting in improved progression free survival and complete response rates. No additional or unexpected toxicities were observed. All randomized patients have an excellent survival to date and longer follow-up will explore factors affecting overall survival in these patients. The PRIMA results indicate that rituximab maintenance should be considered in all follicular lymphoma patients who have responded to first line immunochemotherapy.

302 Background: In the phase III JAVELIN Renal 101 trial (NCT02684006), A + Ax demonstrated progression-free survival (PFS) and objective response rate (ORR) benefit across IMDC risk groups (favorable, intermediate, and poor) vs S in patients with previously untreated aRCC. Here we report efficacy of A + Ax vs S by number of IMDC risk factors (0, 1, 2, 3, and 4-6) and target tumor sites (1, 2, 3, and ≥4) at baseline from the second interim analysis of overall survival (OS). Methods: Patients were randomized 1:1 to receive A 10 mg/kg intravenously every 2 wk + Ax 5 mg orally twice daily or S 50 mg orally once daily for 4 wk (6-wk cycle). PFS and ORR per independent central review (RECIST 1.1) and OS were assessed. Results: At data cut-off (Jan 2019), median (m) follow-up for OS and PFS was 19.3 vs 19.2 mo and 16.8 vs 15.2 mo for the A + Ax vs S arm, respectively. The table shows OS, PFS, and ORR by number of IMDC risk factors and target tumor sites at baseline. A + Ax generally demonstrated efficacy benefit vs S across subgroups. Conclusions: With extended follow-up, A + Ax generally demonstrated efficacy benefit vs S across the number of IMDC risk factors and tumor sites at baseline in aRCC. OS was still immature; follow-up for the final analysis is ongoing. Clinical trial information: NCT02684006 . [Table: see text]
