Abstract Background: Contemporary approaches to non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) incorporate chemo-immunotherapy, biologic combinations, and immune modulating agents; toxicities in elderly pts (³65 years) receiving these therapies are not well studied. Further, clinical and biologic factors predicting these toxicities in pts receiving biologic therapy remain undefined. Methods: We reviewed data on NHL and/or CLL pts treated prospectively on 14 studies by the Alliance for Clinical Trials in Oncology from 2004-2014 (Table 1). Toxicity was assessed per the NCI CTCAE at the time of trial enrollment, and the probabilities of experiencing grade 3 and grade 4 hematologic (hem) and non-hematologic (non-hem) toxicities were modeled as a function of age (³65 years vs. < 65), time on study, treatment (biologics only vs. biologic + chemotherapy), gender, race, LDH, performance status (PS), stage, and an age-by-treatment interaction using logistic regression. Results: A total of 1199 pts (409 age ³ 65; 790 age < 65; 736=CLL and 463=NHL) were included. Among these patients, 493 received only biologic therapy (166 age ³ 65; 327 age < 65; 104 CLL; 389 NHL), and 706 received biologic + chemotherapy (243 age ³ 65; 463 age < 65; 632 CLL; 74 NHL). Among CLL pts (259 pts ³ 65), the effect of age on the probability of experiencing a grade 3 heme toxicity differed by treatment type (age-by-treatment interaction p = 0.047). Specifically, the adjusted odds ratio (OR) (age ³ 65 vs. < 65) for pts receiving only biologic therapy was 3.075 (95% CI: 1,15-8.25), and that for pts receiving biologic + chemotherapy was 1.044 (95% CI: 0.69 - 1.57). Similar results were seen in CLL pts for grade 4 heme toxicities (age-by-treatment interaction p = 0.033; biologic OR 6.937, 95% CI: 1.76-27.35; biologic + chemo OR 1.484, 95% CI: 1.04-2.13). No such interactions were found in CLL pts for grade 3 and 4 non-hem toxicities; however, older pts had significantly higher odds of experiencing a grade 3 non-hem toxicity than younger pts (adjusted OR 1.40; p = 0.047; 95% CI: 1.004-1.96). No age group differences were found in CLL pts for grade 4 non-hem toxicity. Similar analyses were performed for NHL pts (150 pts ³ 65), but no significant age group differences were found. Among CLL pts, women had significantly higher odds of experiencing a grade 3 heme toxicity than men (OR 2.01; p = 0.0007); no difference in grade 3 non-hem or any grade 4 toxicity was noted. Non-Caucasian CLL pts had higher odds of experiencing a grade 4 non-hem toxicity than Caucasians (OR 2.892; p = 0.0029), but no other toxicity differences were found. Worse PS was associated with increased toxicities (OR 1.871; p = 0.0009: grade 3 heme; OR 1.647; p = 0.0025: grade 3 non-hem; OR 1.410; p = 0.0448: grade 4 heme, and OR 1.931; p = 0.0252: grade 4 non-hem). CLL pts with advanced stage disease had higher odds of experiencing a heme toxicity (grade 3: OR 1.95; p = 0.0007, grade 4: OR 1.451; p = 0.0329), but no stage associations were found for non-hem toxicities. Among NHL pts, men had significantly higher odds of experiencing a grade 4 hematologic toxicity than women (OR 4.351; p = 0.0169), but no other toxicity differences were found. An increase in LDH was associated with significantly higher odds of experiencing grade 3 non-hem and grade 4 heme toxicities (grade 3 non-heme: OR 1.633; p = 0.021, grade 4 heme: OR 2.039, p = 0.0182), but no such effect was found for grade 3 heme or grade 4 non-hem. Worse PS was associated with higher odds of experiencing grade 3 toxicities (heme: OR 2.025; p = 0.0344, non-hem: OR 2.458; p = 0.0013), but no such differences were found for grade 4 toxicities. No significant stage or race effects were found in NHL patients. Conclusion: In pts ³65 years who have CLL or NHL, we identified several clinical and disease-related factors as potential predictors of developing grade 3 and/or 4 heme and non-hem toxicities (Table 2). A prognostic model is being constructed to predict toxicities in these under-studied pts to guide management and monitoring. Further, the impact of these toxicities on outcomes is being analyzed and will be presented at the meeting.

Abstract Abstract 3029 Background. In a recent phase 3 trial, bortezomib–melphalan – prednisone–thalidomide followed by maintenance treatment with bortezomib–thalidomide (VMPT-VT) demonstrated superior efficacy compared with VMP. Peripheral neuropathy (PN) was the most important dose limiting toxicity. To decrease neurologic toxicities, the protocol was amended and patients in both arms received once-weekly instead of the initial twice-weekly bortezomib infusions. This post-hoc analysis assessed the impact of bortezomib dose-modification schedule on clinical outcomes and safety. Methods. Patients (N=511) older than 65 years were randomized to receive nine 6-week cycles of VMPT-VT (N=254; induction:V 1.3 mg/m2, d 1, 4, 8, 11, 22, 25, 29, 32, cycles 1–4, d 1, 8, 22, 29, cycles 5–9; M 9 mg/m2 d 1–4, P 60 mg/m2, d 1–4, T 50 mg d 1–42; maintenance: V 1.3 mg/m2 every 14 days and T 50 mg/day) or VMP (N=257) alone. In March 2007, the protocol was amended: both VMPT-VT and VMP induction schedules were changed to nine 5-week cycles and bortezomib schedule was modified to weekly administration (1.3 mg/m2 d 1,8,15,22, all cycles). Patients receiving VMPT-VT and VMP were pooled together and stratified according to the once-weekly or twice-weekly infusion modality; analyses were also conducted for patients receiving VMP only, to eliminate the influence of thalidomide and of maintenance on efficacy and safety. Results. Patients were evaluated in intention-to-treat: 372 patients received once-weekly and 139 twice-weekly bortezomib infusion. Patient characteristics were similar in the two groups, median age was 71 years. The efficacy data did not appear to be affected by the bortezomib schedule. Overall response rates were 85% with once weekly and 86% with twice- weekly schedule (P = .78), including CR rates of 30% and 35% (P = .27).Three-year PFS was 50% in the once-weekly and 47% in the twice-weekly group (P = 1.00), and 3-year OS was 88% and 89%, respectively (P = .54). Similar outcome was seen in the analyses restricted to VMP patients: CR rates were 23% with once-weekly and 27% with twice-weekly schedule (P = .54), 3-years PFS was 46% in once-weekly and 39% (P = .86) in twice-weekly group and 3-years OS was 87% and 89% (P = .47), respectively. The incidence of grade 3/4 hematologic toxicity was similar in the two groups (44% vs 45%, P = .83), but severe thrombocytopenia was slightly less common in the once-weekly patients (19% vs 26%, P = .08).The incidence of non-hematologic grade 3/4 adverse events was significantly reduced in the once-weekly: 35% vs 51% (P = .003). Grade 3/4 gastrointestinal events (6% vs 11%, P = .08), severe systemic events (4% vs 7%, P = .09) and grade 3/4 dermatologic events (2% vs 7%, P = .006) were less frequent in patients receiving once-weekly bortezomib. There was a significantly reduced overall incidence of grade 3/4 PN (8% vs 28%, P < .001) in the once-weekly group. The median time to onset of grade 3/4 sensory PN was 4.3 months in the once-weekly group and 3.2 months in the twice-weekly group (P = .10). The cumulative incidence of sensory PN appeared to plateau after 12 months of therapy in both groups. Rates of discontinuations (5% versus 15%) and dose reductions (15% versus 41%) due to PN were also significantly lower in the once-weekly group (P < .001). These results were reflected in analysis restricted to VMP patients, in which the incidence of grade 3/4 PN (7% vs 29%, P < .001), the discontinuation rate (4% vs 16%, P = 0.002), and the dose reductions rate (15% vs 41% P < 0.001) were significantly lower in once-weekly group. Despite the cumulative planned dose being lower in the once-weekly group (46.8 vs 67.6 mg/m2), the delivered cumulative dose of bortezomib was similar in the two groups (39.4 mg/m2 vs 40.1 mg/m2). No association of PN with age or other baseline characteristics was outlined. The only significant factor influencing the incidence of PN was the reduction of bortezomib infusion from twice- to once-weekly (p<0.001). Low dose thalidomide did not affect grade 3/4 PN rate (p=0.16). Conclusion. These results demonstrate that 1. both once-weekly and twice-weekly schedules in combination with MP ± thalidomide are highly effective in patients ≥ 65 years; 2. once-weekly schedule significantly reduced the incidence of PN and decreased the rate of discontinuation, resulting in similar cumulative bortezomib doses in the two groups; 3. the improvement in the safety profile was not associated with any reduction in the efficacy.

Abstract Introduction: Treatment with dasatinib, a second-generation tyrosine kinase inhibitor (TKI), has resulted in high rates of cytogenetic and molecular responses for pts with CML-CP, both as initial therapy and after failure of other therapies. A reduction in BCR-ABL1 transcript levels to ≤ 10% on the International Scale (IS) at 3 mo is associated with an improved probability of deep molecular responses and superior progression-free and overall survival (PFS and OS). In DASISION, considerably more pts treated with dasatinib achieved BCR-ABL1 ≤ 10% IS compared to imatinib. BCR-ABL1 ≤ 10% IS at 3 mo is considered an optimal response by international guidelines; however, approximately one-third of pts with CML-CP on first-line (1L) imatinib will not achieve this threshold. Clinical studies exploring the potential benefit of early switching to dasatinib in pts with less than optimal responses on initial imatinib treatment have not been reported. Methods: DASCERN (NCT01593254) is a randomized, open-label, international phase 2b trial in adult pts with CML-CP who had achieved complete hematologic response (CHR) but who had BCR-ABL1 > 10% IS at 3 mo after initial treatment with 400 mg imatinib once daily (QD). Imatinib must have been started within 6 mo of the initial CML-CP diagnosis. Pts were randomized 2:1 to receive 100 mg dasatinib QD or continue imatinib at ≥ 400 mg daily with the option for dose escalation. Pts initially randomized in the imatinib cohort who met European LeukemiaNet 2013 failure criteria after randomization and without dasatinib-resistant mutations were crossed over to the dasatinib arm. The primary endpoint in DASCERN is the rate of MMR (BCR-ABL1 < 0.1% IS) at 12 mo after day 1 initiation of 1L imatinib (9 mo after randomization). Secondary endpoints include time to MMR, OS, and PFS (progression was defined as transformation to accelerated/blast phase or death). Tertiary endpoints include safety and tolerability profile of both treatment arms and cytogenetic response over time. Results: All 260 randomized pts (dasatinib: n = 174; imatinib: n = 86) had a minimum follow-up of ≥ 12 mo from the last pts 1st visit (Sokal scores: 28% low, 30% intermediate, 24% high, 18% unknown; median age 37 y [range 18-82, 95% were < 65 y]; 78% male; 73% Asian). All pts had e13a2 or e14a2 transcript types. At the time of analysis, 84% of pts were continuing in the study. Median daily dose was 100 mg QD (range 26-142) for dasatinib and 400 mg QD (range 129-825) for imatinib. Median treatment duration was 111 wk (774 d) in the dasatinib arm and 68 wk (477 d) in the imatinib arm; 42 (49%) imatinib-randomized pts crossed over to dasatinib. Rate of MMR at 12 mo in the intent-to-treat population was 29% (95% confidence interval [CI] 22, 36) for dasatinib and 13% (95% CI 7, 22) for imatinib (P = 0.005); median time to MMR was 14 mo (range 12-18) for dasatinib vs 20 mo (range 14-26) for imatinib (P = 0.053). No differences in the rate of progression or OS were observed between treatment arms. No new safety signals were observed for either treatment arm and the early switch to dasatinib did not increase the toxicity rate. Treatment-emergent pleural effusion (PE; any grade) occurred in 11 (6%) pts randomized to dasatinib and 3 (7%) imatinib-randomized pts who crossed over to dasatinib; treatment-emergent PE grade 3/4 occurred in 1 (1%) pt randomized to dasatinib and 2 (5%) pts randomized to imatinib who crossed over to dasatinib. Hematologic toxicity was similar between treatment arms: neutropenia grade 3/4 occurred in 18 (11%) pts randomized to dasatinib and 12 (29%) pts randomized to imatinib who crossed over to dasatinib; thrombocytopenia grade 3/4 occurred in 18 (11%) pts randomized to dasatinib and in 7 (17%) pts randomized to imatinib who crossed over to dasatinib. Two dasatinib-treated pts discontinued due to hematologic toxicity (1 neutropenia, 1 thrombocytopenia). Conclusions: Early results from DASCERN show that pts with suboptimal responses to imatinib at 3 mo who switched to dasatinib had a significantly increased rate of MMR at 12 mo compared to pts who remained on imatinib. Longer follow-up is required to assess the impact of early switching on PFS and OS, and achievement of deep molecular responses.

Background: Elotuzumab (elo), an immunostimulatory monoclonal antibody targeting signaling lymphocytic activation molecule F7 (SLAMF7, CD319) has shown activity in combination with dexamethasone and lenalidomide (len) or pomalidomide (pom), in patients with relapsed/refractory (RR) multiple myeloma (MM) in the ELOQUENT 2 and 3 trials, respectively. However, patients enrolled on those trials were not refractory to len or pom respectively and the impact of prior daratumumab (dara) (which can deplete natural killer (NK) cells) was not evaluated. We reviewed the outcomes of RR MM patients treated with elo in combination with either len or pom with respect to prior exposure and refractoriness to IMIDs and dara. Methods: We retrospectively evaluated patients with RR MM who were treated at Moffitt Cancer Center between January, 2017 and July, 2019 with elo in combination with len (elo/len) or pom (elo/pom). We assessed prior therapies and refractoriness to IMIDs and dara. Response was evaluated using the International Myeloma Working Group (IMWG) criteria with added minimal response. Grade 3/4 toxicities were reviewed. This study was approved by the Institutional Review Board. Results: Thirty six patients were identified: 14 on elo/len and 22 on elo/pom. Patient characteristics are outlined in the table. As expected, patients that received elo/pom were more heavily pre-treated, than those who received elo/len, with a median number of 6 prior lines of therapy. The median number of cycles was 9 (range, 2-33) and 3 (range, 1-8) for the elo/len and elo/pom groups, respectively. 21/22 (95%) patients in the elo/pom pts were pom-refractory, whereas 11/14 (79%) of the elo/len patients were len-refractory. For elo/len, the overall response rate (ORR) was 42%, and the median progression-free survival (PFS) was 7.7 months (95% confidence interval, 1.99-10.95, p=0.026) although the ORR was 28.6% in len refractory patients. For elo/pom, the ORR was 14% (for pom refractory patients the ORR was 9.1%) and the median PFS 3.7 months (95% confidence interval, 1.27-6.13 p=0.026). Twenty-three patients (64%) were refractory to dara, with a median time from dara to elo of 13.7 (range, 0.7-33.6) months. Overall survival (OS) and PFS based on the median time from dara to elo were not statistically different. The same analysis based on a 6 months cutoff (assuming shorter dara impact on NK cells) yielded similar results. Thirteen patients remain on treatment at the time of this analysis. Reasons for treatment discontinuation were progressive disease (PD) in 22 (95.7%), adverse event (AE) in 1 (4.3%). Grade 3/4 toxicities were noted in two patients; one patient developed pneumonitis, and another developed infectious complication. Conclusion: The combination of elo with an IMID, such as len or pom, is well tolerated. Elo/IMIDs regimen have modest efficacy in len and pom refractory patients respectively. The timing of and prior dara does not appear to impact the efficacy of elo based therapy. Prospective studies are needed to confirm these findings.

Abstract Background Tyrosine kinase inhibitors (TKIs) are the standard of care for pts with CP-CML. Current recommendation is to continue TKI therapy indefinitely but previous studies indicate that pts with deep and sustained molecular responses (MRs) on imatinib (IM) may achieve long-lasting TFR. Nilotinib (NIL) at 300mg BID induces higher rates of deep MRs compared to IM and high dose NIL (400mg BID) enables a substantial proportion of pts who do not obtain MR4 (BCR-ABL1IS £ 0.01%) or MR4.5 (BCR-ABL1IS £ 0.0032%) with IM to reach such deep MRs levels, potentially compatible with TFR. However, optimal duration of treatment with NIL to ensure the highest rate of TFR after treatment discontinuation is unknown. Objective ENESTPath was designed to assess the optimal duration of NIL therapy that is necessary to achieve and maintain TFR upon treatment discontinuation in pts pretreated with IM. Methods ENESTPath is a randomized, phase III study enrolling CP-CML pts who after at least 2 years (yrs) of IM therapy achieved a complete cytogenetic response (CCyR), but not yet a MR4. After enrollment, pts were assigned to receive NIL at 300 mg BID for 2 yrs or 3 yrs (Arm 1 and Arm 2, respectively). Patients who will obtain a stable MR4 or better for at least 12 months (mo) will enter the TFR phase. Primary endpoint is to evaluate the proportion of pts in both arms who will remain in TFR for ≥1 yr after NIL discontinuation. Results 620 pts were enrolled in the study between May-2013 & Apr-2015. In this interim analysis, the first 300 pts (mean age 50.8 yrs; 63.7% male) enrolled and treated with NIL for ≥1 yr have been included. Baseline characteristics are detailed in the Table. By 12 mo of NIL treatment, cumulative incidences of newly acquired MR4 and MR4.5 were 57.4% and 30.5%, respectively. Further analysis of MR4 achievement showed that pts with a major molecular response (MMR: BCR-ABL1IS >0.01% - ≤0.1%) at baseline had a higher probability to achieve a MR4 than those lacking MMR at baseline, with a cumulative incidence of MR4 by 12 months of 64.8% and 30.8%, respectively (Figure). Adverse events (AEs) were mostly of grade 1-2, manageable with supportive care or NIL dose interruption/reduction and included pruritus (19%), headache (9%), skin rash (9%), upper abdominal pain (8%) and constipation (7%). Grade 3-4 hematologic AEs were uncommon. The incidence of grade 3-4 laboratory abnormalities was low: lipase increase, hyperglycemia, ALT and AST increase, hyperbilirubinemia and hypercholesterolemia reported in 3.7%, 1.3%, 1%, 0.7%, 0.3%, 0.3% pts, respectively. Grade 3-4 ischemic cardiovascular events were experienced by 5% of pts including peripheral artery occlusive disease (1.7%) and coronary artery disease (3.7%) (1 pt experienced both AEs). Sub-analyses aiming to evaluate the impact of baseline SCOREa CV risk factor on the onset of arterial ischemic events are currently ongoing. Results on 168 pts showed grade 3-4 ischemic CV events in 19% of pts who were at very high or high risk (n = 47) compared to 1.7% of in pts with moderate or low risk (n = 121). During the first 12 mo, 48 (16%) pts discontinued NIL therapy: 32 discontinued due to AEs/laboratory abnormalities, 12 withdrew consent, 4 due to other reasons (protocol deviation, pregnancy and non-compliance). No patients left the study due to progression to AP/BP. Till date there were no on-treatment deaths. Conclusions This interim analysis shows that a switch to NIL at lower doses than in prior studies (300mg BID instead of 400mg BID) induces high rates of MR4 and MR4.5 in pts without such MR levels on IM. The safety profile of NIL at 300mg BID is consistent with that described in other prospective studies.Thus a switch to NIL for pts not achieving a deep MR during IM therapy is predicted to substantially increase the probability of achieving TFR requirements. A longer follow-up is necessary to assess what may be the best duration of NIL prior to treatment discontinuation. aRisk factors evaluated by applying the SCORE chart proposed by the European Society of Cardiology Table 1.

Background: Multiple myeloma (MM) is common among the elderly, with 35% of patients (pts) diagnosed being aged ≥75 years (y). With increasing overall life expectancy, the incidence and prevalence of newly diagnosed and previously treated MM patients ≥80 y is expected to increase over time. Because elderly pts are often excluded from clinical trials, data focused on their treatment patterns and clinical outcomes are lacking. The Connect® MM Registry (NCT01081028) is a large, US, multicenter, prospective observational cohort study of pts with newly diagnosed MM (NDMM) designed to examine real-world diagnostic patterns, treatment patterns, clinical outcomes, and health-related quality of life patient-reported outcomes. This analysis reviews treatment patterns and outcomes in elderly pts from the Connect MM Registry. Methods: Pts enrolled in the Connect MM registry at 250 community, academic, and government sites were included in this analysis. Eligible pts were adults aged ≥18 y with symptomatic MM diagnosed ≤2 months before enrollment, as defined by International Myeloma Working Group criteria; no exclusion criteria were applied. For this analysis, pts were categorized into 4 age groups: <65, 65 to 74, 75 to 84, and ≥85 y. Pts were followed from time of enrollment to the earliest of disease progression (or death), loss to follow-up, or data cutoff date of February 7, 2019. Descriptive statistics were used for baseline characteristics and treatment regimens. Survival outcomes were analyzed using Cox regression. Time to progression (TTP) analysis excluded causes of death not related to MM. Results: Of 3011 pts enrolled (median age 67 y), 132 (4%) were aged ≥85 y, and 615 (20%) were aged 75-84 y at baseline. More pts aged ≥85 y had poor prognostic factors such as ISS stage III disease and reduced hemoglobin (<10 g/dL or >2 g/dL <LLN) compared with other age groups, although no notable differences between creatinine and calcium levels were observed across age groups (Table). A lower proportion of elderly pts (75-84 and ≥85 y) received triplet regimens as frontline therapy. More elderly pts received a single novel agent, whereas use of 2 novel agents was more common in younger pts (Table). The most common frontline regimens among elderly pts were bortezomib (V) + dexamethasone (D), followed by lenalidomide (R) + D, whereas those among younger pts included RVD, followed by VD and CyBorD (Table). No pt aged ≥85 y, and 4% of pts aged 75-84 y received high-dose chemotherapy and autologous stem cell transplant (vs 61% in the <65 y and 37% in the 65-74 y age group). The most common maintenance therapy was RD in pts ≥85 y (although the use was low) and R alone in other age groups (Table). In the ≥85 y group, 27%, 10%, and 4% of pts entered 2L, 3L, and 4L treatments respectively, vs 43%, 23%, and 13% in the <65 y group. Progression-free survival was significantly shorter in the ≥85 y age group vs the 75-84 y age group (P=0.003), 65-74 y age group (P<0.001), and <65 y age group (P<0.001; Fig.1). TTP was significantly shorter in the ≥85 y group vs the <65 y group (P=0.020); however, TTP was similar among the 65-74 y, 75-84 y, and ≥85 y cohorts (Fig. 2). Overall survival was significantly shorter in the ≥85 y group vs the 75-84 y, 65-74 y, and <65 y groups (all P<0.001; Fig. 3). The mortality rate was lowest (46%) during first-line treatment (1L) in pts aged ≥85 y (mainly attributed to MM progression) and increased in 2L and 3L (47% and 54%, respectively); a similar trend was observed in the younger age groups. The main cause of death was MM progression (29% in the ≥85 y vs 16% in the <65 y group). Other notable causes of death in the ≥85 y group included cardiac failure (5% vs 2% in <65 y group) and pneumonia (5% vs 1% in <65 y group). Conclusions: In this analysis, elderly pts received similar types of frontline and maintenance regimens as younger pts, although proportions varied with decreased use of triplet regimens with age. Considering similarities in TTP across the 65-74 y, 75-84 y, and ≥85 y cohorts, these real-world data support active treatment and aggressive supportive care of elderly symptomatic pts, including with novel agents. Additionally, further clinical studies specific to elderly patients with MM should be explored.

Abstract Background: Corticosteroids are considered standard first-line systemic therapy for patients with aGVHD, but this approach is effective in only approximately half of all cases. For patients who progress or do not respond to corticosteroids, no specific agent has been identified as standard, and regimens are typically selected based on investigator experience and patient co-morbidities. In preclinical models, JAK inhibition has been shown to impair production of cytokines as well as the differentiation and trafficking of T cells implicated in the pathogenesis of aGVHD. Retrospective studies have suggested that JAK1/JAK2 inhibition with ruxolitinib treatment provides clinical benefit in patients with steroid-refractory GVHD (Zeiser et al, Leukemia 2015;29:2062-2068). Herein, we report preliminary safety results from a prospective randomized, parallel-cohort, open-label phase 1 trial evaluating the potent and selective JAK 1 inhibitor INCB039110 in patients with aGVHD. Methods: Male or female patients 18 years or older who underwent their first allo-hematopoietic stem cell transplant (HSCT) from any donor source and developed grades IIB-IVD aGVHD were eligible for the study. Patients were randomized 1:1 to either a 200 or 300 mg oral daily dose of INCB039110 in combination with corticosteroids, and were stratified based on prior treatment status (treatment-naive [TN] versus steroid-refractory [SR]). The primary endpoint of the study was safety and tolerability; secondary endpoints included overall response rate at Days 14, 28, 56, and 100, non-relapse mortality, and pharmacokinetic (PK) evaluations. Patients were assessed through Day 28 for dose-limiting toxicities (DLTs) and response. A Bayesian approach was used for continuous monitoring of DLTs from Days 1-28. Treatment continued until GVHD progression, unacceptable toxicity, or withdrawal from the study. Acute GVHD was graded according to MN-CIBMTR criteria; adverse events (AEs) were graded according to NCICTCAE v 4.03. Results: Between January and June 2016, 31 patients (TN, n=14; SR, n= 17) were randomized. As of July 25, 2016, data were available from 30 patients who received an oral daily dose of 200 mg (n=14) or 300 mg (n=16) INCB039110 in combination with 2 mg/kg methylprednisolone (or equivalent dose of prednisone). The median durations of treatment were 60.8 days and 56.5 days for patients receiving a daily dose of 200 mg and 300 mg INCB039110, respectively. One DLT of Grade 3 thrombocytopenia was reported. The most frequently reported AEs included thrombocytopenia/platelet count decrease (26.7%), diarrhea (23.3%), peripheral edema (20%), fatigue (16.7%), and hyperglycemia (16.7%). Grade 3 or 4 AEs occurred in 77% of patients and with similar frequency across dose groups and included cytomegalovirus infections (n=3), gastrointestinal hemorrhage (n=3), and sepsis (n=3). Five patients had AEs leading to a fatal outcome, including multi-organ failure (n=2), sepsis (n=1), disease progression (n=1), and bibasilar atelectasis, cardiopulmonary arrest, and respiratory distress (n=1); none of the fatal events was attributed to INCB039110. Efficacy and PK evaluations are ongoing and will be updated at the time of presentation. Conclusion: The oral, selective JAK1 inhibitor INCB039110 can be given safely to steroid-naive or steroid-refractory aGVHD patients. The safety profile was generally consistent in both dose groups. Biomarker evaluation, PK, and cellular phenotyping studies are ongoing. The recommended phase 2 dose will be selected and reported based on PK studies and final safety data.

Abstract Introduction : Rd and MPR showed to be effective combinations in elderly newly diagnosed multiple myeloma (NDMM) patients (pts). Cyclophosphamide is a less toxic alkylating alternative agent. EMN01 is the first trial to formally compare these three different Lenalidomide-based combinations. Maintenance with Lenalidomide has been recently approved in patients eligible for autologous stem cell transplant (ASCT). Few data are available about the best combination as maintenance in patients not eligible for ASCT. Methods : 662 pts with NDMM were randomized to receive 9 28-day cycles of Rd (lenalidomide 25 mg/day for 21 days; dexamethasone 40 mg on days 1,8,15 and 22 in pts 65-75 years old and 20 mg in those &gt;75 years), MPR (lenalidomide 10 mg/day for 21 days; melphalan orally 0.18 mg/Kg for 4 days in pts 65-75 years old and 0.13 mg/Kg in &gt;75 years pts; prednisone 1.5 mg/Kg for 4 days) or CPR (lenalidomide 25 mg/day for 21 days; cyclophosphamide orally 50 mg/day for 21 days in pts 65-75 years old and 50 mg every other day in &gt;75 years pts; prednisone 25 mg every other day). After induction, pts were randomized to receive maintenance with lenalidomide alone (R; 10 mg/day for 21 days) or with prednisone (RP; R, 10 mg/day for 21 days and P, 25 mg every other day), until disease progression. Results : Pts characteristics were well balanced in all groups; 217 pts in Rd, 217 in MPR and 220 in CPR arms could be evaluated. After a median follow-up of 63.7 months, median PFS was 23.2 months in MPR, 18.9 months in CPR and 18.6 months in Rd (MPR vs CPR p=0.02; MPR vs Rd p=0.08). Median overall survival (OS) was 79.9 months in MPR, 69.4 months in CPR and 68.1 months in Rd (MPR vs CPR p=0.98; MPR vs Rd p=0.64). The most common grade ≥3 adverse event (AEs) was neutropenia: 64% in MPR, 29% in CPR and 25% in Rd pts (p&lt;0.0001). Grade ≥3 non hematologic AEs were similar among arms. At the end of induction, 402 pts were eligible for maintenance, 198 in the RP and 204 in the R groups. PFS from start of maintenance was 22.2 months in the RP group and 17.6 in the R group, with 20% reduced the risk of death/progression for pts receiving RP maintenance (HR 0.81, p=0.07; Figure 1). A subgroup analysis was performed to determine the consistency of RP vs R treatment effect in different subgroups using interaction terms between treatment and cytogenetic abnormalities, ISS, age, sex, induction treatment and response before maintenance (Figure 1). No difference in OS was observed (HR 1.02, p=0.93) but the OS analysis was limited by the low number of events. Median duration of maintenance was 23.0 months in RP pts and 20.5 months in R pts, 14% and 13% of pts discontinued due to AEs, in RP and R groups, respectively. Conclusion : This phase III trial compared 2 different Lenalidomide-containing induction regimens and 2 different Lenalidomide-containing maintenance regimens in an elderly community-based NDMM population. MPR prolonged PFS by approximately 5 months, yet the higher incidence of hematologic toxicity should be carefully considered. The addition of low-dose prednisone to standard lenalidomide maintenance reduced the risk of death/progression by 20%, with a good safety profile. Updated results will be presented at the meeting.

Introduction: While progress has been made in the treatment of childhood leukemia, the outlook for patients &gt;60 years of age with acute lymphoblastic leukemia (ALL) is poor with complete remission rates (CR) of approximately 60% and 3-year survivals (OS) of less than 15%. Intensified treatment in a later CALGB trial showed little improvement with a CR=61% and 5-year OS=6% (Stock, Cancer 2013). Ixazomib is an oral proteasome inhibitor, which has shown single agent activity and promising combination activity in pediatric ALL patients (Messinger, Blood 2012). We sought to assess the safety and tolerability, as well as early efficacy of adding ixazomib to a current MGH-DFCI/HCC multi-agent regimen for older adults with ALL. Methods: Patients aged 51 to 75 years of age with newly diagnosed B-ALL and T-ALL were screened for eligibility. Patients with mature ALL (including Burkitt's) were excluded. Patients with Philadelphia chromosome positive ALL (BCR-ABL1+) were eligible, and dasatinib was added to the chemotherapy on Day 10 for these patients. The chemotherapy treatment schedule from induction through maintenance is outlined in Table 1. A standard 3 + 3 patient cohort dose escalation design was used to determine the maximum tolerated dose (MTD) of ixazomib during induction for these patients, the primary objective of the trial. After consolidation I, patients in complete remission (CR) with a suitable donor were offered a hematopoietic stem cell transplantation (HSCT) as per institutional guidelines. Those not going to HSCT continued therapy as noted in the table. Results: There were 19 patients with B-ALL enrolled, none with T-ALL. Among these patients, 7 harbored BCR-ABL1 rearrangements. The median age was 65 years, 74% were male, and 90% had a performance status 0 or 1. The MTD was 2.3 mg of ixazomib, as 2 patients at 3.0 mg developed DLT's: a grade 3 peripheral neuropathy and a grade 5 acute kidney injury (Table 2). Grade 3 and 4 toxicities encountered at any time consisted mainly of grade 4 neutropenia in 13 patients and grade 4 thrombocytopenia in 12 patients. One patient experienced grade 3 neutropenia and 5 patients experienced grade 3 thrombocytopenia. Two patients with grade 2 neuropathy did not meet the definition of DLT. Among the 19 patients, 15 (79%, [95% confidence interval (CI), 54-94%]) achieved CR (14) or CRi (1), and 5 patients went on to HSCT. The median follow-up time was 2 years (range, 1-5) for 8 patients remaining alive. The 1-year overall survival estimate was 53% [95% CI, 29-72%], while the 2-year overall survival estimate was 47% [95% CI, 24-67%]. Conclusions: A dose of 2.3 mg of ixazomib in combination with induction chemotherapy among older patients with ALL was well-tolerated and associated with a promising rate of complete remission.

Introduction: Outcomes for acute myeloid leukemia (AML) among older patients has remained largely unchanged for decades. Long-term survival for patients aged &gt;60 years is poor (median survival 10.5 months). Targeting the proteasome in AML is attractive, since leukemia stem cells have demonstrated sensitivity to proteasome inhibition in preclinical models, perhaps through down regulation of nuclear NF-KB (Guzman, Blood 2001). AML cell lines are susceptible to synergistic cytotoxicity when bortezomib, a proteasome inhibitor, is combined with daunorubicin and cytarabine. We have shown that adding bortezomib to standard treatment in AML results in a high remission rate, although grade 2 sensory neurotoxicity was noted in approximately 12% of treated patients. A newer generation proteasome inhibitor, ixazomib, is less frequently associated with neurotoxicity, and, therefore, was selected for combination with conventional chemotherapy in this phase I trial. The primary objective of this study was to determine the maximum tolerated dose (MTD) of ixazomib in combination with conventional induction and consolidation chemotherapy for AML. Herein are the initial results of this trial. Methods: Adults &gt;60 years of age with newly diagnosed AML were screened for eligibility. Patients with secondary AML were eligible, including those with prior hypomethylating agent therapy for myelodysplastic syndromes (MDS). We excluded those with promyelocytic leukemia. There were 2 phases in this study. In the first phase (A), the induction treatment consisted of the following: cytarabine 100 mg/m2/day by continuous IV infusion, Days 1-7; daunorubicin 60 mg/m2/day IV, Days 1, 2, 3, and ixazomib was provided orally at the cohort dose, Days 2, 5, 9, and 12. Consolidaton or transplant was at the discretion of the treating physician in phase A. In the second phase (B), induction was the same as that with the determined MTD of ixazomib. All patients were to be treated with the following consolidation: cytarabine at 2 g/m2/day, days 1-5 with ixazomib on days 2, 5, 9, and 12 at the cohort dose for consolidation. A standard 3 + 3 patient cohort dose escalation design was used to determine whether the dose of ixazomib could be safely escalated in 3 cohorts (1.5 mg/day, 2.3 mg/day, 3.0 mg/day), initially in induction (phase A) and subsequently in consolidation (phase B). The determined MTD of ixazomib in the first portion (A) of the trial was used during induction in the second portion (B), which sought to determine the MTD for ixazomib during consolidation. Secondary objectives included rate of complete remission, disease-free survival, and overall survival (OS). Results: Thirty-six patients have been enrolled on study, and 28 have completed dose levels A-1 through A-3 and B1 through B-2. Full information on cohort B-3 has not yet been obtained, hence, this report covers the experience with the initial 28 patients, cohorts A-1 through B-2. There were 12 (43%) patients among the 28 with secondary AML, either with prior hematologic malignancy or therapy-related AML. Nineteen patients (68%) were male, and the median age was 68 years (range 61-80 years). There have been no grade 5 toxicities due to study drug. Three patients died early due to leukemia, 2 of which were replaced for assessment of the MTD. Nearly all the grade 3 and 4 toxicities were hematologic (Table). There was 1 DLT (grade 4 platelet count decrease extending beyond Day 42). There has been no grade 3 or 4 neurotoxicity with ixazomib to date. Among the 28 patients in the first 5 cohorts, 22 achieved complete remissions (CR) and 2 achieved CRi, for a composite remission rate (CCR) of 86%. Among the 12 patients with secondary AML 8 achieved CR and 2 achieved CRi, for a CCR of 83%. The median OS for the 28 patients has not been reached (graph). The 18-month OS estimate was 65% [90% CI, 50-85%]. Conclusions: The highest dose level (3 mg) of ixazomib planned for induction in this trial has been reached safely. For consolidation there have been no serious safety issues in the first 2 cohorts with a dose up to 2.3 mg, apart from 1 DLT in the form of delayed platelet count recovery. The recommended phase 2 dose of ixazomib for induction is 3 mg. Accrual to cohort B-3 is ongoing. Notably, to date, no grade 3 or 4 neurotoxicity has been encountered. The remission rate in this older adult population with the addition of ixazomib to standard chemotherapy appears favorable.

Background: The combination of carfilzomib with immunomodulatory drugs (IMiDs) and dexamethasone is active in multiple myeloma (MM). Carfilzomib, thalidomide, and dexamethasone (KTd) has been studied in upfront MM treatment but has not been studied in the setting of relapsed/refractory myeloma (RRMM). The ALLG MM018/ AMN002 is an open-label phase II study of KTd in patients with RRMM. This study was conducted across 16 sites across Australia, New-Zealand, Singapore, South Korea and Taiwan. Method: Patients with RRMM with 1-3 prior lines of treatment were given carfilzomib [K: 20mg/m2 IV cycle 1 days 1 and 2, 56mg/m2 (36mg/m2 for patients age ≥75 years) from cycle 1 day 8 onwards], thalidomide (T: 100mg po nocte) and dexamethasone [dex: 40mg (20mg for patients age ≥75 years) po weekly], in a 28-day cycle. After 12 cycles, T was omitted, and K was given on days 1,2,15,16 and dex days 1,15 every 28-day cycles for a further six cycles. The primary endpoint was PFS. Secondary endpoints were ORR, overall survival, adverse events, and quality of life (QoL). The study had an 80% power to detect a ≥70% PFS at 6.5 months compared to historical ≤50% PFS at 6.5 months expected with Td (Kropff, M. et al. Haematologica 2012), at a significance level of 0.05. Results: This study has completed accrual. Eighty-three patients [median age of 66 years (42-85)] were enrolled with a median follow up of 15.9 (0.9-26) months. ORR rates were 86.4% (≥VGPR 70.2%). Median PFS was 20m (95% CI 15.9-26m). PFS at 6.5 months was 76.2% (95% CI 73.6-84.9%). Median OS has not been reached, and was 75% at 20 months. The most common grade ≥3/4 AEs were peripheral neuropathy (16%), upper respiratory tract infections (12%), dyspnoea (14%), and hypertension (10%). Grade ≥3/4 cardiac AEs occurred in 6%. The median carfilzomib dose that was delivered was 70.7% (32.8-92.6%) of the target dose. Thus far, 41% of patients have completed the intended 18 cycles of treatment. 21% of patients ceased therapy early. The most common reason for early treatment cessation was disease progression (30%) and adverse events (15%). Fifteen patients (18%) have died, 11 were due to MM, two from infection, one from an ischaemic cardiac event, and one from a traffic accident. QoL, as measured by the EQ-5D-5L instrument, remained stable throughout treatment. Conclusion: The ALLG MM018/AMN 002 study has met its primary endpoint. The KTd schedule as outlined in this study is efficacious in patients with RRMM, resulting in a prolonged PFS and a safety profile in line with previous reports for each of carfilzomib and thalidomide. KTd is an active option in jurisdictions where the cost of other IMiDs prohibits regulatory funding. Comparisons of efficacy and adverse events between the Caucasian and Asian populations will be presented at the meeting.
