Abstract RESONATE-2 is a phase 3 study of first-line ibrutinib versus chlorambucil in chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). Patients aged ≥65 years (n = 269) were randomized 1:1 to once-daily ibrutinib 420 mg continuously or chlorambucil 0.5–0.8 mg/kg for ≤12 cycles. With a median (range) follow-up of 60 months (0.1–66), progression-free survival (PFS) and overall survival (OS) benefits for ibrutinib versus chlorambucil were sustained (PFS estimates at 5 years: 70% vs 12%; HR [95% CI]: 0.146 [0.098–0.218]; OS estimates at 5 years: 83% vs 68%; HR [95% CI]: 0.450 [0.266–0.761]). Ibrutinib benefit was also consistent in patients with high prognostic risk (TP53 mutation, 11q deletion, and/or unmutated IGHV) (PFS: HR [95% CI]: 0.083 [0.047–0.145]; OS: HR [95% CI]: 0.366 [0.181–0.736]). Investigator-assessed overall response rate was 92% with ibrutinib (complete response, 30%; 11% at primary analysis). Common grade ≥3 adverse events (AEs) included neutropenia (13%), pneumonia (12%), hypertension (8%), anemia (7%), and hyponatremia (6%); occurrence of most events as well as discontinuations due to AEs decreased over time. Fifty-eight percent of patients continue to receive ibrutinib. Single-agent ibrutinib demonstrated sustained PFS and OS benefit versus chlorambucil and increased depth of response over time.

Abstract Ibrutinib, a once-daily oral inhibitor of Bruton tyrosine kinase, has greatly improved outcomes for patients with chronic lymphocytic leukemia (CLL). The phase 3 RESONATE trial, which compared single-agent ibrutinib to ofatumumab in high-risk, relapsed patients with CLL, provided support for approval of ibrutinib in the United States and Europe. We describe long-term follow-up of patients treated in RESONATE, where continued superiority of progression-free survival (PFS) (hazard ratio [HR], 0.133; 95% confidence interval [CI], 0.099-0.178) was observed. Overall survival benefit continues (HR, 0.591; 95% CI, 0.378-0.926), although with decreased magnitude relative to that seen before crossover to ibrutinib was implemented for patients on ofatumumab (HR, 0.426; 95% CI, 0.220-0.823). Notably, overall response to ibrutinib increased over time, with 91% of patients attaining a response. The PFS benefit with ibrutinib was independent of baseline risk factors, although patients with ≥2 prior therapies had shorter PFS than those with <2 prior therapies, and the presence of TP53 or SF3B1 mutations showed a trend toward shorter PFS vs without these factors. Median duration of ibrutinib was 41 months, with 46% remaining on treatment at a median follow-up of 44 months. Grade ≥3 adverse events generally decreased over time, causing only a small proportion of patients to cease therapy. Ibrutinib was discontinued due to progressive disease in 27% of patients. This long-term study provides support for sustained efficacy and safety of ibrutinib in relapsed/refractory CLL and consideration of study provisions that allow crossover to investigational therapy when benefit has been clearly demonstrated. This trial was registered at www.clinicaltrials.gov as #NCT01578707.

7523 Background: Ibrutinib, a once-daily Bruton’s tyrosine kinase inhibitor, is the only targeted therapy with significant progression-free survival (PFS) and overall survival (OS) benefit in multiple randomized phase 3 studies versus established therapies in patients (pts) with previously untreated chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Extended long-term follow-up data for the RESONATE-2 study of first-line ibrutinib vs chlorambucil in older pts with CLL/SLL are reported. Methods: In the phase 3 RESONATE-2 study, older pts (≥65 years [y]) with previously untreated CLL/SLL and without del(17p) (N=269) were randomly assigned 1:1 to once-daily single-agent ibrutinib 420 mg until disease progression (PD) or unacceptable toxicity (n=136) or chlorambucil 0.5–0.8 mg/kg up to 12 cycles (n=133). Outcomes included PFS, OS, overall response rate (ORR), and safety. Long-term responses were investigator-assessed per 2008 iwCLL criteria. Results: With up to 7y of follow-up (median, 74.9 months; range, 0.1–86.8), significant PFS benefit was sustained for pts treated with ibrutinib vs chlorambucil (hazard ratio [HR] 0.160 [95% confidence interval (CI): 0.111–0.230]). At 6.5y, PFS was 61% in pts treated with ibrutinib vs 9% in pts treated with chlorambucil. This PFS benefit was observed across all subgroups, including in ibrutinib-treated pts with high-risk genomic features of unmutated IGHV (HR 0.109 [95% CI: 0.063–0.189]) or del(11q) (HR 0.033 [95% CI: 0.010–0.107]). OS at 6.5y was 78% with ibrutinib treatment. ORR was 92% for ibrutinib-treated pts with complete response (CR/CRi) rate increasing to 34% with this follow-up. Ongoing rates of grade ≥3 adverse events (AEs) of interest remained low for hypertension (5–6y interval: 5%, n=4; 6–7y: 4%, n=3) and atrial fibrillation (5–6y: 1%, n=1; 6–7y: 1%, n=1); no grade ≥3 major hemorrhage occurred in 5–7y. Dose reductions due to grade ≥3 AEs occurred in 1% (n=1) of pts during the 5–6y and 6–7y intervals. Across full follow-up, 31 pts had dose reductions due to any-grade AEs of whom 22/31 (71%) had resolution or improvement the AE. Primary reason for discontinuations in 5–7y was PD (5–6y: 5%, n=4; 6–7y: 6%, n=4). Any-grade AEs leading to discontinuations were seen in 3% (n=2) of pts from 5–6y and none in 6–7y. With over 7y of follow-up, 47% of pts remain on single-agent ibrutinib. Conclusions: Extended long-term data from RESONATE-2 demonstrate the sustained PFS and OS benefit of first-line ibrutinib treatment for pts with CLL, including for pts with high-risk genomic features. Responses continue to deepen over time. Rates of grade ≥3 AEs of interest continued to be low at up to 7y follow-up and further discontinuations and dose reductions due to AEs were rare; most AEs leading to dose reduction resolved or improved. Ibrutinib remains well tolerated with no new safety signals observed. Clinical trial information: NCT01722487, NCT01724346.

8004 Background: D-VTd plus ASCT was approved for transplant-eligible (TE) NDMM based on part 1 of CASSIOPEIA. We report a prespecified interim analysis of CASSIOPEIA part 2: DARA maintenance vs OBS in pts with ≥partial response (PR) in part 1, regardless of induction/consolidation (ind/cons) treatment. Methods: CASSIOPEIA is a 2-part, randomized, open-label, phase 3 study in TE NDMM. Pts received 4 cycles ind and 2 cycles cons with D-VTd or VTd. 886 pts who achieved ≥PR were rerandomized to DARA 16 mg/kg IV Q8W for up to 2 yr (n = 442) or OBS (n = 444) until progressive disease per IMWG. Pts were stratified by ind (D-VTd vs VTd) and depth of response (minimum residual disease [MRD] status and post cons response ≥PR). Primary endpoint was progression-free survival (PFS) after second randomization. This interim analysis assessed efficacy and safety after 281 PFS events. A preplanned hierarchical procedure tested key secondary endpoints: time to progression (TTP), ≥complete response (CR), MRD negativity rates by NGS and overall survival (OS). Results: At median follow-up of 35.4 mo, median PFS was not reached (NR) with DARA and 46.7 mo with OBS (HR 0.53; 95% CI 0.42–0.68; P <0.0001). PFS advantage for DARA was consistent across most subgroups. However, a prespecified analysis showed significant interaction with ind/cons treatment arm ( P< 0.0001). PFS HR for DARA vs OBS was 0.32 (95% CI 0.23–0.46) in the VTd arm and 1.02 (0.71–1.47) in the D-VTd arm. Median TTP was NR for DARA vs 46.7 mo for OBS (HR 0.49; 95% CI 0.38–0.62; P <0.0001). More pts in the DARA vs OBS arm achieved ≥CR (72.9% vs 60.8%; OR 2.17; 95% CI 1.54–3.07; P <0.0001). MRD negativity (in ≥CR pts at 10-5) was 58.6% with DARA vs 47.1% with OBS (OR 1.80; 95% CI 1.33–2.43; P= 0.0001). Median OS was NR in either arm. Most common (≥2.5%) grade 3/4 adverse events (AEs) with DARA vs OBS were pneumonia (2.5% vs 1.4%), lymphopenia (3.6% vs 1.8%), and hypertension (3.0% vs 1.6%). Serious AEs occurred in 22.7% (DARA) vs 18.9% (OBS) of pts; the most common (≥2.5%) was pneumonia (2.5% vs 1.6%). 13 (3.0%) pts discontinued DARA due to an AE. The rate of infusion-related reactions was 54.5% (DARA-naïve pts) and 2.2% (prior DARA pts); 90% were grade 1/2.Second primary malignancies occurred in 5.5% (DARA) vs 2.7% (OBS) of pts. Conclusions: CASSIOPEIA part 2 demonstrated a clinical benefit of DARA maintenance in TE NDMM pts, with significantly longer PFS for DARA vs OBS. With current follow-up, maintenance PFS benefit appeared only in pts treated with VTd as ind/cons. Pts who received D-VTd ind/cons with or without DARA maintenance achieved similar PFS; longer follow-up is needed for PFS2 and OS. DARA significantly increased deeper response and MRD negativity rates vs OBS, and was well tolerated with no new safety signals. Clinical trial information: NCT02541383.

Abstract Abstract 539 Introduction: The addition of rituximab to fludarabine-based regimens in CLL has been shown to produce high response rates with extended remissions. The long-term follow-up of these regimens with respect to progression, survival, and development of secondary malignancies has been limited. Patients and Methods: We report the long-term follow up of the chemoimmunotherapy trial CALGB 9712 (Blood 2003;101:6-14). This trial randomized 104 untreated, symptomatic patients to receive either 6 monthly cycles of fludarabine plus rituximab (FR) followed 2 months later by 4 weekly doses of rituximab (concurrent arm) or 6 monthly cycles of single agent fludarabine followed by rituximab consolidation using 4 weekly doses (sequential arm). With a median follow up of 92 months (range: 60-107), we analyzed the updated CALGB database and flow sheets submitted by treating physicians. Results: The overall response rate (ORR) was 84% (95% CI: 77%-91%), with a 90% ORR in the concurrent group (95% CI: 82%-98%) and a 77% ORR in the sequential group (95% CI: 66%-89%). Complete response (CR) was seen in 38% of patients (95% CI: 30%-45%), and partial response (PR) in 46% (95% CI: 38%-54%). The median OS was 85 months (95% CI: 71-95), with 71% of patients alive at 5 years (95% CI: 61%-79%). The median PFS was 37 months (95% CI: 27-45), with 27% progression-free at 5 years (95% CI: 19%-36%). With long-term follow up, the estimated median OS and PFS for the concurrent group were 84 months (95% CI: 57-100) and 32 months (95% CI: 23-55), respectively; the median OS and PFS for the sequential group were 91 months (95% CI: 71-110) and 40 months (95% CI: 23-50), respectively. Patients with del(17p13.1)/del(11q22.3)(18 patients) and unmutated IgVH(43 patients) continue to have an inferior OS (P=0.01 and P=0.04, respectively) and PFS (P=0.03 and P=0.04, respectively) compared to those without these abnormalities. We next assessed the frequency of therapy-related myeloid neoplasms (t-MN) and other cancers occurring after this chemoimmunotherapy regimen. No patient has developed MDS or AML prior to relapse. One patient (1%) developed t-MDS following relapse and receipt of FCR 41 months after completing trial therapy; t-MDS was diagnosed 9 months later. Richter's transformation was noted in three (3%) of the CALGB 9712 patients with large cell (n=2) or Hodgkin lymphoma (n=1). Second malignancies have included localized basal cell or squamous cell skin cancer in 12 (12%) patients whereas 11 (11%) have developed other epithelial malignancies including 4 GI, 3 lung, 3 melanomas, and 1 prostate cancer. Conclusions: Long-term follow up of patients enrolled on CALGB 9712 demonstrates extended OS and PFS with fludarabine plus rituximab, given either concurrently or sequentially, with an estimated 17%(95% CI: 9%-27%) of responders still in remission 8 years later. Looking at other published data, patients treated with FR administered concurrently or sequentially do not appear to have an increased risk of t-MN or second cancers. These long-term data reaffirm that FR is one of several acceptable frontline treatments for symptomatic patients with CLL. Disclosures: Morrison: Genentech: Speakers Bureau.

Abstract Background: Ibrutinib (ibr), a first-in-class, once-daily Bruton's tyrosine kinase inhibitor, is approved by the US FDA for treatment of patients (pts) with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) including pts with del17p. The phase 1b/2 PCYC-1102 trial showed single-agent efficacy and tolerability in treatment-naïve (TN; O'Brien, Lancet Oncol 2014) and relapsed/refractory (R/R) CLL/SLL (Byrd, N Engl J Med 2013). We report efficacy and safety results of the longest follow-up to date for ibr-treated pts. Methods: Pts received 420 or 840 mg ibr QD until disease progression (PD) or unacceptable toxicity. Overall response rate (ORR) including partial response (PR) with lymphocytosis (PR-L) was assessed using updated iwCLL criteria. Responses were assessed by risk groups: unmutated IGVH, complex karyotype (CK; ≥3 unrelated chromosomal abnormalities by stimulated cytogenetics assessed by a reference lab), and in hierarchical order for del17p, then del11q. In the long-term extension study PCYC-1103, grade ≥3 adverse events (AEs), serious AEs, and AEs requiring dose reduction or discontinuation were collected. Results: Median age of the 132 pts with CLL/SLL (31 TN, 101 R/R) was 68 y (range, 37-84) with 43% ≥70 y. Baseline CK was observed in 41/112 (37%) of pts. Among R/R pts, 34 (34%) had del17p, 35 (35%) del11q, and 79 (78%) unmutated IGVH. R/R pts had a median of 4 prior therapies (range, 1-12). Median time on study was 46 m (range, 0-67) for all-treated pts, 60 m (range, 0-67.4) for TN pts, and 39 m (range, 0-67) for R/R pts. The ORR (per investigator) was 86% (complete response [CR], 14%) for all-treated pts (TN: 84% [CR, 29%], R/R: 86% [CR, 10%]). Median progression-free survival (PFS) was not reached (NR) for TN and 52 m for R/R pts with 60 m estimated PFS rates of 92% and 43%, respectively (Figure 1). In R/R pts, median PFS was 55 m (95% confidence intervals [CI], 31-not estimable [NE]) for pts with del11q, 26 m (95% CI,18-37) for pts with del17p, and NR (95% CI, 40-NE) for pts without del17p, del11q, trisomy 12, or del13q. Median PFS was 33 m (95% CI, 22-NE) and NR for pts with and without CK, and 43 m (95% CI, 32-NE) and 63 m (95% CI, 7-NE) for pts with unmutated and mutated IGVH, respectively(Figure 2). Among R/R pts, median PFS was 63 m (95% CI, 37-NE) for pts with 1-2 prior regimens (n=27, 3 pts with 1 prior therapy) and 59 m (95% CI, 22-NE) and 39 m (95% CI, 26-NE) for pts with 3 and ≥4 prior regimens, respectively. Median duration of response was NR for TN pts and 45 m for R/R pts. Pts estimated to be alive at 60 m were: TN, 92%; all R/R, 57%; R/R del17p, 32%; R/R del 11q, 61%; R/R unmutated IGVH, 55%. Among all treated pts, onset of grade ≥3 treatment-emergent AEs was highest in the first year and decreased during subsequent years. With about 5 years of follow-up, the most frequent grade ≥3 AEs were hypertension (26%), pneumonia (22%), neutropenia (17%), and atrial fibrillation (9%). Study treatment was discontinued due to AEs in 27 pts (20%) and disease progression in 34 pts (26%). Of all treated pts, 38% remain on ibr treatment on study including 65% of TN pts and 30% of R/R pts. Conclusions: Single-agent ibrutinib continues to show durable responses in pts with TN or R/R CLL/SLL including those with del17p, del11q, or unmutated IGVH. With extended treatment, CRs were observed in 29% of TN and 10% of R/R pts, having evolved over time. Ibrutinib provided better PFS outcomes if administered earlier in therapy than in the third-line or beyond. Those without CK experienced more favorable PFS and OS than those with CK. Ibrutinib was well tolerated with the onset of AEs decreasing over time, allowing for extended dosing for 65% of TN and 30% of R/R pts who continue treatment.

7533 Background: Classical Hodgkin’s lymphoma (cHL) is characterized by chromosome 9p24.1 alterations and PD-1 ligand overexpression. Sintilimab, a programmed death-1 checkpoint inhibitor, has demonstrated efficacy in relapsed/refractory cHL after the primary analysis of the ORIENT-1 study. Here, we report the updated safety and efficacy prolines after extended follow-up. Methods: ORIENT-1 is a multicenter, single-arm, phase II study in China. Classical Hodgkin’s lymphoma patients who had failed ≥2 lines of systemic therapy, including autologous hematopoietic stem cell transplantation (HSCT) were enrolled. Sintilimab, 200 mg IV was given every 3 weeks, until disease progression, death, unacceptable toxicity, or withdrawal from study. The primary endpoint was objective response rate (ORR) assessed by an independent radiological review committee (IRRC) according to 2007 IWG criteria. Results: 96 patients were treated. As of the data cutoff on 16 October, 2018 72.9% of patients were continuing treatment with a median follow-up of 14 months. Median number of treatment cycles was 20 (range: 1 to 26). ORR was 85.4% (82/96, 95%CI: 76.7 to 91.8) based on IRRC review. Twenty-eight patients (29.2%) achieved complete response (CR) by PET scan. At the time of analysis, 59 out of 82 patients who had achieved complete or partial response continued to have an on-going response. The median duration of response (DoR) and progression free survival (PFS) have not been reached. The most common treatment-related adverse event (TRAE) was pyrexia (40.6%, 39/96), 92.3% of which was grade 1 or 2. The most common grade 3 or 4 TRAEs were pyrexia (3.1%) and anemia (3.1%). One death occurred which was not considered treatment related. Conclusions: ORIENT-1 study has the largest cohort of cHL patients in China treated with a PD-1. In addition to a high rate of response, sintilimab also demonstrated durable efficacy and favorable long-term safety profile after extended follow-up. Clinical trial information: NCT03114683.

7528 Background: Previously in the COMPLEMENT 1 study, treatment with OFA and CHL in pts with untreated CLL had shown a significant improvement in the progression-free survival (PFS) compared with CHL alone, and was well tolerated. Here, we report the final overall survival (OS) analysis of the 5-year (y) follow-up, updated investigator-assessed PFS and safety from the study. Methods: Untreated pts, not fit for fludarabine-based therapy (due to advanced age or co-morbidities) were randomized 1:1 to OFA+CHL or CHL alone. Pts in OFA+CHL arm received OFA (Cycle 1: 300 mg day (d) 1, 1000 mg d8; subsequent cycles: 1000 mg d1) in addition to CHL (10 mg/m2, d1-7) for 3 to 12 cycles of 28 d each. Pts in CHL arm received CHL only. Results: Overall, 447 pts were randomized to OFA+CHL (n = 221) or CHL (n = 226); 168 (76%) and 164 (73%) pts completed the scheduled treatments, respectively. Baseline characteristics were similar in both arms. The investigator-assessed median PFS was 23.4 months (mos) in the OFA+CHL arm and 14.7 mos in the CHL arm (HR: 0.61 [95% CI 0.49, 0.76], p < 0.001). Median OS could not be estimated for the OFA+CHL arm and was 84.7 mos for the CHL arm (HR: 0.88 [95% CI 0.65, 1.17], p = 0.363). Estimated OS rate (95% CI) at 5 y was 68.5% (61.5%, 74.5%) in the OFA+CHL arm, and 65.7% (58.6%, 71.9%) in the CHL arm. Post-treatment anti-cancer therapy after discontinuation was received by a greater proportion of pts in the CHL (66%) vs. OFA+CHL (56%), and started earlier in the CHL arm (486 d) vs. OFA+CHL (743 d) arm. Overall, 84 (39%) pts in the OFA+CHL, and 99 (44%) pts in the CHL arms died during the study with 5 on-treatment deaths in each group. Grade ≥3 adverse events were seen in 64% and 48% of pts in the OFA+CHL vs. CHL arms, respectively, most common being (≥5% in either arm) neutropenia (26% vs. 15%), thrombocytopenia (5% vs. 10%), pneumonia (9% vs. 5%), and anemia (5% vs. 5%). Conclusions: This 5-y survival follow-up analysis supported the results from primary analysis with an estimated 12% (not significant) and 39% risk reduction in OS and PFS, respectively, in the OFA+CHL arm compared with the CHL arm. No new safety concerns were observed in the OFA+CHL arm. Clinical trial information: NCT00748189.

Key Points In a 3-year follow-up of the DASatinib versus Imatinib Study In treatment-Naive CML patients trial, first-line dasatinib resulted in faster and deeper responses compared with imatinib. Deeper responses at 3, 6, and 12 months were associated with better 3-year progression-free survival and overall survival.

Hazard Ratios

Purpose Taxanes (paclitaxel or docetaxel) have been sequenced or combined with anthracyclines (doxorubicin or epirubicin) for the first-line treatment of advanced breast cancer. This meta-analysis uses data from all relevant trials to detect any advantages of taxanes in terms of tumor response, progression-free survival (PFS), and survival. Patients and Methods Individual patient data were collected on eight randomized combination trials comparing anthracyclines + taxanes (+ cyclophosphamide in one trial) with anthracyclines + cyclophosphamide (+ fluorouracil in four trials), and on three single-agent trials comparing taxanes with anthracyclines. Combination trials included 3,034 patients; single-agent trials included 919 patients. Results Median follow-up of living patients was 43 months, median survival was 19.3 months, and median PFS was 7.1 months. In single-agent trials, response rates were similar in the taxanes (38%) and in the anthracyclines (33%) arms (P = .08). The hazard ratios for taxanes compared with anthracyclines were 1.19 (95% CI, 1.04 to 1.36; P = .011) for PFS and 1.01 (95% CI, 0.88 to 1.16; P = .90) for survival. In combination trials, response rates were 57% (10% complete) in taxane-based combinations and 46% (6% complete) in control arms (P < .001). The hazard ratios for taxane-based combinations compared with control arms were 0.92 (95% CI, 0.85 to 0.99; P = .031) for PFS and 0.95 (95% CI, 0.88 to 1.03; P = .24) for survival. Conclusion Taxanes were significantly worse than single-agent anthracyclines in terms of PFS, but not in terms of response rates or survival. Taxane-based combinations were significantly better than anthracycline-based combinations in terms of response rates and PFS, but not in terms of survival.
