PFS2 In Elderly Patients With Newly Diagnosed Multiple Myeloma (NDMM): Results From The MM-015 Study

Abstract Introduction In a phase 3 trial of transplant non-eligible elderly (≥ 65 yrs) patients (pts) with NDMM, the combination of melphalan-prednisone-lenalidomide (LEN) followed by LEN maintenance (MPR-R) reduced the risk of progression by 60% compared with 9 cycles of MP (HR=0.40; P < 0.001) and by 51% compared with 9 cycles of MPR (HR=0.49; P < 0.001) (Palumbo, NEJM. 2012). The progression-free survival (PFS) benefit was seen in all patient types. With a median follow-up of 53 mos, the median overall survival (OS) was similar across the 3 treatment (Tx) groups (54 mos for MPR-R vs. 52 mos for MPR vs. 55 mos for MP) (Dimopoulos, ASH 2012; abstract 944). The similar OS benefit seen across the 3 arms could be due in part to the availability of more effective Tx options in subsequent lines of therapy. Assessment of PFS2, defined as the time from initial randomization to time of objective disease progression (PD) after next-line of therapy or death from any cause, has recently been proposed as a surrogate for OS, particularly for trials evaluating maintenance Tx (EMA guideline, www.ema.europa.eu). Therefore, data from MM-015 were analyzed to estimate PFS2 in pts treated with MPR-R, MPR, or MP. Methods The MM-015 study design has been previously described (Palumbo, NEJM. 2012). Refractory multiple myeloma pts who progressed during MM-015 study could receive LEN 25 mg (D1–21/28-day cycle) ± dexamethasone 40 mg (on days 1–4, 9–12, and 17–20) as part of an open-label extension phase, or any other anti-myeloma Tx outside of the protocol as part of the follow-up phase. The data of PD following 2nd-line Tx was not collected prospectively; therefore, the start of 3rd-line Tx was used as a surrogate for analyzing the PFS2 endpoint. The assessment included data up to July 31, 2012 (median follow-up: 53 mos after initial randomization). Results A total of 459 pts were randomized to MPR-R (n= 152), MPR (n= 153), or MP (n= 154). At the time of the data cut-off, fewer pts in the MPR-R group had started 2nd-line Tx (53%) compared with the MPR and MP groups (77% and 82%, respectively) due to the improved PFS seen with MPR-R in the 1st-line setting. Most pts in the MP group “crossed over” to receive LEN as 2nd-line Tx (72%); choice of 2nd-line Tx in the MPR-R group was heterogeneous (Table). Median PFS2 was significantly higher with MPR-R (39.7 mos) vs. MP (28.5 mos; HR=0.71; log-rank P = 0.013) (Figure). The safety profile of continuous therapy with LEN was predictable and manageable with little evidence of cumulative toxicity and low second primary malignancy risk (Delforge, IMW 2013: abstract O-17). Conclusion PFS2 was markedly improved in the MPR-R group vs. the MP group. LEN provided a durable progression-free interval also when including the impact of 2nd-line Tx, confirming the clinical benefits of continuous LEN Tx. The benefit of MPR-R was apparent regardless of subsequent Tx; long-term treatment with LEN did not affect the efficacy of subsequent therapy. Use of continuous LEN in the 1st-line setting in combination with MP is more beneficial than sequential use of MP and LEN. PFS and PFS2 were improved with MPR-R; OS was similar among the 3 Tx groups; the reason for this is unclear, but may be related to the impact of subsequent Tx (i.e., 3rd and 4th line), which was more frequently needed in the MPR and MP groups.

Triplet Regimen

Abstract Introduction: Triplet therapies are used for treatment (Tx) of both transplant-eligible and -ineligible patients (pts) with newly diagnosed multiple myeloma (NDMM). Actual patterns and outcomes of Tx are not fully understood. Connect MM® is the first and largest multicenter, US-based, prospective observational cohort study designed to characterize Tx patterns and outcomes for pts with NDMM. This analysis describes demographic and disease characteristics of pts who received triplet Tx as an induction regimen and for whom transplant was or was not intended. The analysis explores the relationship of these factors with overall survival (OS) and other efficacy endpoints. Patients and Methods: Pts aged ≥ 18 y with NDMM within 60 days of diagnosis were eligible for enrollment regardless of disease severity, medical history, or comorbidities. Data including transplant intent (yes/no) was collected at baseline; follow-up data was collected quarterly thereafter. Based on the initial intent, 2 groups were identified: patients with intent to transplant who received transplant (TT) and pts with no intent to transplant who did not receive a transplant (NT). Triplet Tx was defined as the combination of ≥ 3 concurrent therapeutic agents in the first course of Tx (within 56 days of study entry). KM analysis adjusted for age was conducted for OS. Because decisions on use of transplant and triplet therapy are influenced by multiple factors, a multivariable Cox regression analysis was performed to evaluate the contribution of the triplet therapy (yes/no) to OS and was adjusted for other variables, including age, comorbidities, and ISS staging. Results: Between September 2009 and December 2011, 1493 pts were enrolled. This analysis was on 1436 pts: 650 pts with transplant intent and 786 pts without transplant intent. The data cutoff date was November 30, 2014, and the median follow-up for overall survival (OS) was 33.8 mos. Of pts with transplant intent, 451 (69%) received transplant (TT) and 199 (31%) did not. Of pts without transplant intent, 62 (8%) received transplant and 724 (92%) did not (NT). The abstract focuses on TT and NT groups only. NT pts tended to be older and have more advanced ISS staging and higher β2-microglobulin levels than TT pts (Table). The most common triplet regimen given during the first course treatment (within 56 days) was lenalidomide, bortezomib, and dexamethasone (RVd). RVd was administered to 34% of the NT pts (76/225) and 59% of the TT pts (152/257). The most common non-triplet regimen was bortezomib and dexamethasone (Vd), which was given to 31% of NT pts (156/499) and 38% of TT pts (73/194). Within the NT group, pts given triplet Tx had a lower risk of death than those who did not receive triplet Tx (P = .0013). The multivariable analysis found triplet Tx to be associated with a 36% reduced risk of death (hazard ratio [HR] = 0.64 [95% CI, 0.50-0.82]; P = .001). ISS disease stage (HR = 1.43 [95% CI, 1.21-1.69]; P < .001) and history of diabetes (HR = 1.38 [95% CI, 1.08-1.78]; P = .012) were negative prognostic factors for OS. Within the TT group, pts who received triplet Tx did not attain an OS benefit (P = .8993), and no baseline characteristics were significantly associated with OS. These results may be limited by other factors not considered that may have influenced physicians' choice of treatment, including the use of maintenance therapy and a short follow-up period of 33.8 months. Conclusions: Triplet Tx as a first regimen is associated with longer OS in pts without transplant intent who did not receive a transplant. RVd and Vd were the most common first Tx regimens, respectively. Continued follow-up of these pts and enrollment of an additional cohort will provide additional data with mature follow-up. Table 1.

Abstract Abstract 3859 Poster Board III-795 The initial results of the pivotal, international, phase III VISTA trial demonstrated the superiority of bortezomib (Velcade®) plus melphalan–prednisone (VMP) versus MP alone across all efficacy end points, including overall survival (OS), in previously untreated multiple myeloma (MM) patients ineligible for high-dose therapy (San Miguel et al, N Engl J Med 2008). We conducted a planned updated survival analysis of VISTA after a median >3 years of follow-up and with the majority of patients having received subsequent therapy. We confirmed the previously demonstrated OS benefit of VMP versus MP, examined the use of subsequent therapy and its efficacy following VMP and MP, and evaluated the survival of patients who had received subsequent therapy. Patients were randomized to receive nine 6-week cycles of VMP (N=344; bortezomib 1.3 mg/m2, d 1, 4, 8, 11, 22, 25, 29, 32, cycles 1–4, d 1, 8, 22, 29, cycles 5–9; melphalan 9 mg/m2 d 1–4, prednisone 60 mg/m2, d 1–4, all cycles) or MP (N=338) alone. Response was assessed using EBMT criteria with central laboratory M-protein analysis. After disease progression, patients were followed for survival and subsequent therapy, including investigator-assessed best response to subsequent therapies. The median age of patients was 71 years, 30% were aged ≥75 years, 34% had ISS stage III MM, and 33% had β2-microglobulin >5.5 mg/L. After median follow-up of 36.7 months, there was a 35% reduced risk of death with VMP vs MP (hazard ratio [HR] 0.653, p=0.0008); median OS was not estimable vs 43.1 months, and 3-year OS rates were 68.5% vs 54.0% with VMP vs MP, respectively. This OS benefit was seen consistently across patient subgroups predefined by baseline characteristics. Within the VMP arm, OS was longer among patients aged <75 vs ≥75 years (HR 1.664, p=0.011; 3-year OS: 74.1% vs 55.5%); by contrast, there were no significant differences, although there were trends to longer OS among patients with creatinine clearance ≥60 versus <60 mL/min (HR 1.291, p=0.238; 3-year OS: 74.5% vs 63.1%) and patients with standard- vs high-risk cytogenetics (HR 1.346, p=0.399; 3-year OS 71.6% vs 56.1%). At data cut-off (16 March 2009), 178 (52%) VMP and 233 (69%) MP patients had received subsequent therapy; median time to subsequent therapy (28.1 vs 19.2 months, HR 0.527, p<0.0001) and median treatment-free interval (17.6 vs 8.4 months, HR 0.543, p<0.0001) were superior with VMP vs MP. Receipt of and response to subsequent bortezomib-, thalidomide-, and lenalidomide-based therapy are summarized in the Table. Median survival from start of subsequent therapy following VMP and MP was 30.2 vs 21.9 months (HR 0.815, p=0.21) among all patients receiving subsequent therapy. This updated analysis of VISTA confirms that VMP results in significantly longer OS compared with MP, despite 50% of MP patients being rescued with bortezomib-based therapy in the relapsed setting. VMP treatment used upfront appears more beneficial than treating with conventional agents and saving bortezomib- and other novel-agent-based treatment until relapse. Subsequent therapies appeared similarly effective in the VMP and MP arms, with our analysis also demonstrating the benefit of retreatment with bortezomib-based therapies following VMP. In addition, post-relapse survival among all patients receiving subsequent therapy appeared longer following VMP, indicating that frontline bortezomib use does not induce more resistant relapses.

Abstract Introduction: Triplet regimens incorporating a proteasome inhibitor and immunomodulatory drug are standards of care for the treatment of patients with newly diagnosed multiple myeloma (NDMM). The combinations of carfilzomib-lenalidomide-dexamethasone (KRd) and bortezomib-lenalidomide-dexamethasone (VRd) are recommended regimens for the treatment of NDMM by the National Comprehensive Care Network. However, there are limited data directly comparing the relative effectiveness and tolerability of these two regimens in patients with NDMM. Here, we report prospective evaluation of efficacy and preliminary tolerability data for patients who received KRd or VRd as frontline therapy in the Multiple Myeloma Research Foundation (MMRF) Clinical Outcomes in MM to Personal Assessment of Genetic Profile (CoMMpass, NCT01454297) study. Methods: CoMMpass is a prospective observational study conducted since 2011 by the MMRF that has enrolled over 1100 patients from Multiple Myeloma Research Consortium sites. Eligible adults with NDMM and symptomatic disease were enrolled within 30 days of initiating frontline therapy. Frontline therapy was chosen at the discretion of the investigator but must have included a proteasome inhibitor and/or immunomodulatory drug. In the current analysis, we evaluated the effectiveness and reasons for treatment discontinuation among enrolled patients who received KRd or VRd as first-line therapy. KRd patients were matched to VRd patients based on propensity score matching including age, gender, ISS and renal insufficiency as covariates. Treatment response was assessed by investigators and defined by International Myeloma Working Group Uniform Response Criteria. Event-free survival (EFS) was the pre-specified primary endpoint and defined as the time from the start of treatment until disease progression, death, or the initiation of new therapy. EFS was compared between treatment groups using a Cox proportional hazards model. Results: A total of 609 evaluable patients received first-line KRd (n=149) or VRd (n=460). Of these, 149 KRd patients and 149 VRd patients were matched according to baseline co-variates. Patient demographics and disease characteristics were balanced between treatment arms for the matched set of patients (KRd vs VRd) including by median age (years, 58 vs 59), gender (male, 63% vs 62%), and ISS (stage I, 46% vs 53%; stage II, 41% vs 40%; stage III, 13% vs 7%). With median follow up of 11.5 months for KRd and 41.9 months for VRd, 12-month EFS rates (95% CI) were 95% (90-99%) for KRd vs 84% (78-90%) for VRd (12-month HR, 0.28; 95% CI, 0.10-0.75; p=0.0043; Figure 1). By 12 months, 87% (95% CI, 81-93%) of KRd patients vs 68% (95% CI, 60-76%) of VRd patients had a partial response or better (p=0.0029) and 35% (95% CI, 25-45%) of KRd patients vs 14% (95% CI, 8-20%) of VRd patients achieved a complete response or better (p=0.0054; Figure 2). The treatment discontinuation rate due to adverse events was 3.4% for each arm. Conclusions: In the CoMMpass study, KRd demonstrated significant improvements in 12-month EFS compared with VRd in patients with NDMM (HR, 0.28; 95% CI, 0.10-0.75; p=0.0043). By 12 months, patients treated with KRd also achieved significantly higher response rates and complete response rates or better compared with VRd treated patients. Discontinuation rates due to AEs were similar between KRd and VRd. With limitations of non-randomized evaluation and relatively short median follow-up in the KRd arm, these results are consistent with previous single arm studies that KRd is not only effective but potentially a superior treatment option compared with VRd for patients with NDMM. Updated results with extended follow-up will be presented.

Abstract Abstract 4591 Introduction: Clinicians and investigators appreciate the value of measuring HRQOL for monitoring CLL and the impact of treatments, and commonly use ECOG performance status (PS) and clinician-reported patient fatigue as surrogates for HRQOL in clinical practice. However, limited data exist on the relationships between PS, fatigue, and HRQOL in CLL patients (pts) undergoing treatment in clinical practices. We examined the associations between these measures and 3 psychometrically validated, patient-reported, HRQOL instruments: the Brief Fatigue Inventory (BFI), EQ-5D, and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu). Methods: Data were collected as part of Connect CLL®, a prospective observational registry initiated in March 2010 involving US practices. Data on pt demographics and clinical characteristics were provided by clinicians. HRQOL was self-reported by pts at enrollment using the BFI, EQ-5D, and FACT-Leu. Mean BFI, EQ-5D and FACT-Leu scores were analyzed by ECOG PS and clinician-reported fatigue. Differences in HRQOL scores between sub-cohorts were assessed by ANOVA. Results: HRQOL data were reported by 604 pts enrolled from 10 academic, 148 community, and 3 government centers. Pts were predominantly male (62%) and white (90%); mean age was 70 (standard deviation 11) years. BFI data (scale: 0 [no fatigue] - 10 [worst fatigue]) indicated that on average pts report that global fatigue, fatigue severity and fatigue-related interference worsen by ECOG severity (Table 1) and are statistically associated with clinician-reported fatigue (Table 2). Mean EQ-5D overall HRQOL as measured by a Visual Analogue Scale (VAS) from 0 (worst) to 100 (best) worsens by ECOG severity and is significantly worse in pts with fatigue. Mean EQ-5D domain scores (scale: 1 [no problem], 2 [some problems], 3 [incapacity]) indicated that pain/discomfort, mobility and usual activities increase in severity as ECOG worsens and in pts with fatigue. FACT-Leu domains except social/family were statistically worse with worse ECOG PS and in pts with fatigue. Conclusions: Initial results from Connect CLL® indicate that HRQOL worsens with worsening ECOG PS, especially in physical / functioning domains, pain/discomfort, and mobility, and worsens across multiple domains among pts whose physicians reported fatigue. Future analyses should be conducted on how HRQOL, PS and fatigue may change over time with changes in CLL, and how they are influenced by therapies. These results may serve as baseline reference.

Abstract Abstract 801 Background: Ruxolitinib is a potent JAK1 & 2 inhibitor that has demonstrated superiority over traditional therapies for the treatment of MF. In the two phase 3 COMFORT studies, ruxolitinib demonstrated rapid and durable reductions in splenomegaly and improved MF-related symptoms and quality of life. COMFORT-II is a randomized, open-label study evaluating ruxolitinib versus BAT in patients (pts) with MF. The primary and key secondary endpoints were both met: the proportion of pts achieving a response (defined as a ≥ 35% reduction in spleen volume) at wk 48 (ruxolitinib, 28.5%; BAT, 0%; P < .0001) and 24 (31.9% and 0%; P < .0001), respectively. The present analyses update the efficacy and safety findings of COMFORT-II (median follow-up, 112 wk). Methods: In COMFORT-II, 219 pts with intermediate-2 or high-risk MF and splenomegaly were randomized (2:1) to receive ruxolitinib (15 or 20 mg bid, based on baseline platelet count [100-200 × 109/L or > 200 × 109/L, respectively]) or BAT. Efficacy results are based on an intention-to-treat analysis; a loss of spleen response was defined as a > 25% increase in spleen volume over on-study nadir that is no longer a ≥ 35% reduction from baseline. Overall survival was estimated using the Kaplan-Meier method. Results: The median follow-up was 112 wk (ruxolitinib, 113; BAT, 108), and the median duration of exposure 83.3 wk (ruxolitinib, 111.4 [randomized and extension phases]; BAT, 45.1 [randomized treatment only]). Because the core study has completed, all pts have either entered the extension phase or discontinued from the study. The primary reasons for discontinuation were adverse events (AEs; ruxolitinib, 11.6%; BAT, 6.8%), consent withdrawal (4.1% and 12.3%), and disease progression (2.7% and 5.5%). Overall, 72.6% of pts (106/146) in the ruxolitinib arm and 61.6% (45/73) in the BAT arm entered the extension phase to receive ruxolitinib, and 55.5% (81/146) of those originally randomized to ruxolitinib remained on treatment at the time of this analysis. The primary reasons for discontinuation from the extension phase were progressive disease (8.2%), AEs (2.1%), and other (4.1%). Overall, 70 pts (48.3%) treated with ruxolitinib achieved a ≥ 35% reduction from baseline in spleen volume at any time during the study, and 97.1% of pts (132/136) with postbaseline assessments experienced a clinical benefit with some degree of reduction in spleen volume. Spleen reductions of ≥ 35% were sustained with continued ruxolitinib therapy (median duration not yet reached); the probabilities of maintaining the spleen response at wk 48 and 84 are 75% (95% CI, 61%-84%) and 58% (95% CI, 35%-76%), respectively (Figure). Since the last report (median 61.1 wk), an additional 9 and 12 deaths were reported in the ruxolitinib and BAT arms, respectively, resulting in a total of 20 (14%) and 16 (22%) deaths overall. Although there was no inferential statistical testing at this unplanned analysis, pts randomized to ruxolitinib showed longer survival than those randomized to BAT (HR = 0.52; 95% CI, 0.27–1.00). As expected, given the mechanism of action of ruxolitinib as a JAK1 & 2 inhibitor, the most common new or worsened grade 3/4 hematologic abnormalities during randomized treatment were anemia (ruxolitinib, 40.4%; BAT, 23.3%), lymphopenia (22.6%; 31.5%), and thrombocytopenia (9.6%; 9.6%). In the ruxolitinib arm, mean hemoglobin levels decreased over the first 12 wk of treatment and then recovered to levels similar to BAT from wk 24 onward; there was no difference in the mean monthly red blood cell transfusion rate among the ruxolitinib and BAT groups (0.834 vs 0.956 units, respectively). Nonhematologic AEs were primarily grade 1/2. Including the extension phase, there were no new nonhematologic AEs in the ruxolitinib group that were not observed previously (in ≥ 10% of pts), and only 1 pt had a new grade 3/4 AE (epistaxis). Conclusion: In COMFORT-II, ruxolitinib provided rapid and durable reductions in splenomegaly; this analysis demonstrates that these reductions are sustained over 2 years of treatment in the majority of pts. Ruxolitinib-treated pts showed longer survival than those receiving BAT, consistent with the survival advantage observed in previous (Verstovsek et al. NEJM. 2012) and current analyses of COMFORT-I, as well as with the comparison of pts of the phase 1/2 study with matched historical controls (Verstovsek et al. Blood. 2012).

Abstract Background In adults, ITP (characterized by platelet counts <100x109/L) is typically chronic, with remission reported infrequently ≥3 y post-diagnosis (Sailer, Haematol 2006). The TPO-mimetic romiplostim increases platelet counts and reduces use of concomitant ITP medications in chronic ITP. While often perceived as a long-term treatment, dose adjustment rules allow romiplostim to be discontinued when hemostatic platelet counts are reached, as reported in Amgen trials (pivotal trials, 2011 EHA, 2011 ASH) and case reports. Methods Data from 8 romiplostim trials (4 phase 3, 2 single-arm, and 2 extension trials) were examined for cases in which patients receiving romiplostim subsequently had ≥26 consecutive wks of platelet counts ≥50x109/L without romiplostim or any other ITP medications. The number of evaluable patients could not be calculated as many trials had dosing rules that did not allow for the reduction of romiplostim in patients with platelet counts <400x109/L (making remission unlikely), treatment durations varied by study, and follow-up data were not always available. Results Twenty-seven patients had ≥26 wk of platelet counts ≥50x109/L without romiplostim or any other ITP medications (Table; data from 4 of these patients were presented at ASH 2011). These patients had characteristics of median (Q1, Q3) time since ITP diagnosis of 2.1 (0.5, 4.2) y, with 17/27 having ITP >1 y, mean (SD) baseline platelet count of 20.9 (15.41) x109/L, median (Q1, Q3) age of 49.0 (36.0, 67.0) y, and mean (SD) maximum dose prior to remission of 4.6 (3.6) µg/kg. Of the 27 patients, 12 (44%) were splenectomized at baseline and 15 (56%) were male. Patients had from 40 to 276 cumulative wks of romiplostim with doses ranging from 0.1 to 4.3 µg/kg. Prior to romiplostim treatment, minimum platelet counts ranged from 1-37x109/L and individual average platelet counts ranged from 1-152x109/L. On treatment, minimum (1-182x109/L) and average (121-654x109/L) platelet counts ranged widely. The median (Q1, Q3) time to remission was 7.1 (1.9, 12.7) months. Only 3 patients (3, 6, 15) had bleeding of grade 3; the remainder had either bleeding of grade 1 or 2 or none. Conclusions The patient population who entered clinical remission (platelet counts ≥50x109/L for 26 wks) after treatment with romiplostim generally had: ITP of less than 5 y duration, a wide range of ages (23-78 y), about equal proportions of men and women, were as likely to be splenectomized as not, and no significant bleeding. Therefore, it is difficult to predict which patients would have this response. Reporting of these cases was not predefined, so a prospective assessment, such as the phase 2 single-arm study currently underway (NCT01143038), will provide a more comprehensive evaluation of remission with romiplostim. Potential mechanisms for the phenomenon of remission, both in early and late stages of ITP, may involve T-regulatory cell function, increased numbers/activity of natural killer T-cells, or increased B-regulatory cell activity.

Abstract Background: Diagnostic and therapeutic advances have significantly improved the outcomes for multiple myeloma (MM) patients. However, pts who are refractory to or relapse after therapy with immune modulatory drugs and proteasome inhibitors remain a therapeutic challenge. Comprehensive genomic profiling via clinical next generation sequencing (NGS)-based assays studies of MM cases have revealed multiple targetable mutations that were previously unexploited in MM. Methods: Between June 2013 and May 2014 we performed genomic profiling of 351 patients who had progressed after initial therapy to assist physicians in therapy planning. Comprehensive genomic profiling was performed using the FoundationOne¨ or FoundationOne Heme¨ assays. FoundationOne assays 374 cancer-related and 24 frequently rearranged genes via DNA-seq, and FoundationOneHeme assays 405 cancer-related and 31 frequently rearranged genes via DNA-seq as well as 265 frequently rearranged genes by RNA-seq. All samples were sequenced in a CLIA-certified CAP-accredited laboratory to an average depth >500x . Patients with activating alterations of KRAS, NRAS or BRAF were considered for therapy with the targeted agent trametinib (TMTB) as were patients who had a gene expression signature suggesting activation of the MAPK pathway. Retrospective review of this case series was approved by the UAMS institutional review board. Results: We identified 63 patients who underwent treatment with Trametinib. 60 were treated based on activating mutations of KRAS, NRAS or BRAF and 3 were treated based on a GEP signature. The median age was 65 and patients had a median of 5 lines of prior therapy (range 1-20). 38 of 63 patients had prior treatment with Total Therapy. 43 underwent salvage with chemotherapy prior to initiation of TMTB, 15 had salvage transplants, 33 patients were exposed to novel agents (Pomalidomide, Carfilzomib) and 33 had Metronomic therapy before TMTB. 25% of patients were ISS stage 3 and 37% had GEP70 defined high risk. 13 had PET defined extra medullary disease (EMD). 41 patients were administered TMTB monotherapy and 22 received TMTB treatment in combination with other agents. In general the treatment was well tolerated. 10 patients discontinued therapy because of toxicities, 29 discontinued because of disease progression or death. None of the deaths were attributed to TMTB, Best treatment responses were SD in 30, PR in 8, VGPR in 2 and CR in 3 of the 63 pts. For 25 patients with evaluable PET data, treatment resulted in complete resolution of FDG avid lesions in 9 patients and a better than 50% reduction in 15 (Figure 1). We will present updated data on clinical responses as well as toxicities. Conclusions: Treatment with targeted therapy guided by prospective comprehensive genomic profiling across all classes of genomic alterations in this heavily pretreated population of MM patients resulted in an unexpectedly high objective response rate. Observation of CR with TMTB monotherapy further supports continued investigation of this individualized approach to MM management. Disclosures Van Laar: Signal Genetics: Employment, Equity Ownership.

Abstract Introduction: Panobinostat is a potent pan-deacetylase inhibitor (pan-DACi) that targets key aberrations in multiple myeloma (MM) cell biology, including epigenetics and protein metabolism. In the phase 3 clinical trial PANORAMA 1, panobinostat in combination with bortezomib and dexamethasone (PAN-BTZ-Dex) led to a statistically significant and clinically relevant increase in progression-free survival of approximately 4 months compared with that with placebo plus bortezomib and dexamethasone (Pbo-BTZ-Dex). Further analyses of patient outcomes by prior treatment demonstrated that the magnitude of PFS benefit was greatest among patients who received at least 2 prior regimens, including bortezomib and an immunomodulatory drug (IMiD; PAN-BTZ-Dex [n = 73]: 12.5 months [95% CI, 7.3-14.0 months]; Pbo-BTZ-Dex [n = 74]: 4.7 months (95% CI, 3.7-6.1 mo; HR 0.47 [95% CI, 0.32-0.72]). These data supported the regulatory approvals of PAN-BTZ-Dex for the treatment of patients with multiple myeloma who received at least 2 prior regimens, including bortezomib and an IMiD. Here we present the final analysis of overall survival (OS) for the entire patient population and among patients who received at least 2 prior regimens, including bortezomib and an IMiD. Methods: The study design for the PANORAMA 1 trial was described previously (San-Miguel. Lancet Oncol. 2014;15:1195-206). The key secondary endpoint was OS. As of June 29, 2015, the 415 events required to conduct the final analysis of OS had been observed. Kaplan-Meier estimation was utilized for OS analyses for the entire population (N = 768), the pre-specified subgroup of patients who received prior bortezomib and IMiD (n = 193), and patients who received at least 2 prior regimens including bortezomib and an IMiD (n = 147). Results: The median OS of patients who received PAN-BTZ-Dex in the overall population was 40.3 months (95% CI, 35.0-44.8 months) vs 35.8 months (95% CI, 29.0-40.6 months) for the Pbo-BTZ-Dex arm with HR 0.94 [95% CI, 0.78-1.14], P = .5435 (Fig 1A). The percentage of patients in each arm who received post-study therapy was 37.7% in the PAN-BTZ-Dex arm and 48.8% in the Pbo-BTZ-Dex arm. The median OS of patients who received at least 2 prior lines, including bortezomib and an IMiD, was 25.5 months (95% CI, 19.6-34.3 months) in the PAN-BTZ-Dex arm vs 19.5 months (95% CI, 14.1-32.5 months) in the Pbo-BTZ-Dex arm (Fig. 1B). The proportion of patients in this subgroup who received post-study therapy was 35.6% in the PAN-BTZ-Dex arm and 66.2% in the Pbo-BTZ-Dex arm. Conclusion: For the overall PANORAMA 1 study population, patients in the PAN-BTZ-Dex arm demonstrated an increase in median OS of 4.5 months vs patients in the Pbo-BTZ-Dex arm, but this result was not statistically significant (P = .5435). Median OS was also slightly longer for the PAN-BTZ-Dex arm among the more heavily pretreated subgroup of patients who received at least 2 prior regimens, including bortezomib and an IMiD. A higher percentage of patients on the Pbo-BTZ-Dex arm received post-study therapy vs the PAN-BTZ-Dex arm, which may have confounded the OS results. In summary, PAN-BTZ-Dex demonstrates statistically significant increases in PFS vs Pbo-BTZ-Dex in patients with relapsed or relapsed and refractory MM; however, this did not translate to a statistically significant increase in OS. Future trials will plan to focus on further optimization of dose and schedule of panobinostat and bortezomib to improve outcome, as well as novel combinations with other agents, including IMiDs and next-generation proteasome inhibitors.

Abstract Introduction. Prognosis of patients (pts) with R/R Philadelphia chromosome-positive (Ph+) ALL is dismal despite the introduction of tyrosine kinase inhibitors (TKI) which may be used as single agents or in combination regimens. Blinatumomab is a bispecific T-cell engaging (BiTE®) antibody construct that has shown antileukemic activity. Among adults with R/R Ph-negative ALL receiving blinatumomab, 43% achieved complete remission (CR) or CR with partial hematologic recovery (CRh) during the first two cycles (Topp MS et al. Lancet Oncol 2015;16:57). We evaluated the efficacy and tolerability of blinatumomab in pts with R/R Ph+ ALL who progressed after or were intolerant to a 2nd or later (2+) generation TKI. Methods. Eligible adult pts (≥18 years) had Ph+ B-precursor ALL and had relapsed after or were refractory to at least one 2+ generation TKI; or were intolerant to 2+ generation TKI and intolerant or refractory to imatinib. All pts had to have >5% blasts in the bone marrow and Eastern Cooperative Oncology Group performance status ≤ 2. Blinatumomab was dosed by continuous IV infusion (4 weeks on/2 weeks off) for up to 5 cycles (9 μg/d on days 1-7 in cycle 1, and 28 μg/d thereafter). The primary endpoint was CR or CRh during the first two cycles; minimal residual disease (MRD) response based on RT-PCR amplification of BCR-ABL per central laboratory, relapse-free survival (RFS), overall survival (OS), and allogeneic hematopoietic stem cell transplant (alloHSCT) rate were key secondary endpoints. Complete MRD response was defined as no RT-PCR amplification of BCR-ABL at a sensitivity of 10-5. Results. Of 45 treated pts, 44 were resistant to 2+ generation TKI; one patient was resistant to imatinib and never exposed to 2+ generation TKI (protocol deviation). 53% of pts were men. Median (range) age was 55 (23-78) years (≥65 years, 27%). Ten pts (22%) had a BCR-ABL gene with T315I mutation. All pts had received prior TKI (dasatinib, 87%; ponatinib, 51%; imatinib, 56%; nilotinib, 36%; bosutinib, 2%), with 60% having received ≥ 2 prior 2+ generation TKI; most pts (96%) had received prior chemotherapy. 38% of pts had ≥ 2 prior relapses and 44% had prior alloHSCT. Efficacy outcomes for key endpoints are shown in the table. 16 pts achieved CR/CRh during the first two cycles for a response rate of 36% (95% CI: 22%, 51%); of those, 14 pts achieved CR, most of them (10/14, 71%) in cycle 1. The patient who never received 2+ generation TKI did not respond to treatment. 12 of the 14 pts (86%) with CR and two of the two pts with CRh achieved a complete MRD response. Among the 10 pts with T315I mutation, four achieved CR/CRh; all four also achieved a complete MRD response. Eight CR/CRh responders (50%) relapsed, three during treatment (including two with CR who did not achieve complete MRD response). One patient died in CR post alloHSCT. Median (95% CI) RFS was 6.7 (4.4, not estimable) months (median follow-up, 9.0 months); median OS was 7.1 (5.6, not estimable) months (median follow-up, 8.8 months). Patient incidence of grade ≥ 3 treatment-emergent adverse events (AEs) was 82%, most commonly febrile neutropenia (27%), thrombocytopenia (22%), anemia (16%), and pyrexia (11%). Five pts had fatal AEs; one (septic shock) was considered treatment-related by the investigator. Three pts discontinued because of AEs. Cytokine release syndrome (CRS) occurred in three pts (all grade 1 or 2). 21 pts (47%) had neurologic events (paraesthesia, 13%; confusional state, 11%; dizziness, 9%; tremor, 9%); three pts had grade 3 neurologic events (aphasia, hemiplegia; and depressed level of consciousness and nervous system disorder), one of which (aphasia) required treatment interruption. Conclusion. In this population of pts with R/R Ph+ ALL who have very poor prognosis after failure of 2+ generation TKI therapy, treatment with CD19-targeted immunotherapy blinatumomab as single agent showed antileukemic activity. AEs were consistent with those previously reported for pts with R/R Ph-negative ALL treated with blinatumomab. Table 1. Table 1.

Abstract Background: Thrombocytopenia occurs in ~50% of patients with low/int-1 risk myelodysplastic syndrome (MDS) and is associated with reduced survival. In a placebo (PBO)-controlled study, 250 patients with MDS were randomized 2:1 to receive weekly romiplostim or PBO. In the original June 2011 analysis, romiplostim reduced clinically significant bleeding events [hazard ratio (HR) romiplostim vs PBO 0.83, 95% CI: 0.66−1.05, P = 0.13] and platelet transfusions (relative risk 0.77, 95% CI: 0.66−0.88, P<0.001) and increased IWG hematologic improvement platelets (HI-P) incidence (odds ratio 15.6, 95% CI: 4.7−51.8, P<0.001). Peripheral blast count increases >10% were more frequent with romiplostim (25/167, 15%) than PBO (3/83, 3.6%) and resolved after discontinuation in most cases. In February 2011, the DMC recommended that treatment with study drug be discontinued as the potential benefit seen in the reduction of bleeding did not outweigh the potential risk for disease progression to AML, and that transient increases in blast cell counts might put patients at risk for diagnosis of and treatment for AML. Patients were moved into long-term follow-up (LTFU). Previously reported (Giagounidis et al, Cancer 2014) 58-week incidence of AML was 6.0% (N = 10) for romiplostim and 4.9% for PBO (N = 4); HR 1.20 (95% CI: 0.38−3.84). This report provides final 5-year LTFU data. Methods: Eligible patients were receiving only supportive care and had IPSS low/int-1 risk MDS and platelets 1) ≤20 × 109/L or 2) ≤50 × 109/L with a history of bleeding. Disease progression to AML was defined as 1) ≥20% blasts in bone marrow or peripheral blood after 4 weeks following discontinuation of romiplostim; 2) pathology consistent with leukemia; or 3) antileukemic treatment. Results are presented by treatment group. Results: At baseline, median (Q1, Q3) age was 70 (61, 77) years, the majority (59%) of patients were male; 27.6% were IPSS low risk and 72.4% were int-1 risk. WHO classifications were RCMD: 67.6%, RAEB-1: 13.2%, MDS-U: 11.2%, RA: 4.4%, RCMD-RS: 2.4%, RARS: 0.8%, and RAEB-2: 0.4%. Of 250 patients in the study, 210 entered LTFU and 66 completed the 5 years of LTFU; median (Q1, Q3) follow-up was 27.5 (10.8, 58.7) months. Reasons for discontinuation (death, lost to follow-up, and consent withdrawal) during LTFU were similar in both groups. During the active study period and LTFU, death was reported in 93 (55.7%) patients in the romiplostim group and 45 (54.2%) patients in the PBO group (HR romiplostim vs PBO 1.03, 95% CI: 0.72−1.47) (Figure); mortality rates were greater in those with IPSS int-1 vs low risk for both groups (Table). AML was reported in 20 (11.9%) patients in the romiplostim group and 9 (11.0%) patients in the PBO group (HR 1.06, 95% CI: 0.48−2.33). The proportions of patients who either died or developed AML were 56.9% (N = 95) in the romiplostim group and 55.4% (N = 46) in the PBO group (HR for AML-free survival 1.04, 95% CI: 0.73−1.48) (Figure). Nearly half (N = 14, 48%) of the 29 AML cases occurred in patients who were RAEB-1 at screening (none RAEB-2), and 6 cases were diagnosed because of anti-AML treatment use alone (Table). In LTFU, patient-reported use of MDS therapy (eg, azacitidine or cyclosporine) was 42.8% (N = 59, 95% CI: 34.4%−51.5%) in the romiplostim group and 31.4% (N = 22, 95% CI: 20.9%−43.6%) in the PBO group. AML therapy (eg, chemotherapy) was used in 14 (10.2%) patients in the romiplostim group and 7 (10.0%) patients in the PBO group. Conclusions: Following the decision in 2011 to stop study drug secondary to increased AML rates at that time and transient blasts increases, final 5-year LTFU HRs (romiplostim vs placebo) for death or progression to AML, respectively, are 1.03 (95% CI: 0.72−1.47) and 1.06 (95% CI: 0.48−2.33). In conclusion, romiplostim reduced bleeding events and platelet transfusions, with no increase in AML incidence or impact on survival. Disclosures Kantarjian: Amgen Inc.: Research Funding.
