Abstract Background: Vosaroxin, is a first-in-class anti-cancer quinolone derived (AQD) DNA intercalator and topoisomerase II inhibitor, which is not a substrate for p53 or P-glycoprotein, and is currently under evaluation for the treatment of pts with AML and high-risk MDS. Methods: Pts are eligible if they have AML or high-risk MDS (defined as having >/= 10% blasts), are 60 years of age or older, and have adequate performance status (ECOG </= 2) and organ function. In the phase I part of the study the first six pts received vosaroxin 90 mg/m2 daily on days 1 and 4 with decitabine 20 mg/m2 daily for 5 days repeated in approximately 4 to 5 week intervals for up to 7 cycles. This dose was well tolerated in the 6 patients. However, due to occurrence of 8 episodes of grade 3/4 mucositis in 7 of the subsequent 16 patients the induction dose of vosaroxin was reduced to 70 mg/m2 with the vosaroxin dose maintained at 70 mg/m2 or reduced to 50 mg/m2 in consolidation cycles. 34 patients were treated at this modified dose regimen. The primary endpoint was to determine the overall response rate including complete response (CR) + CR without platelet recovery (CRp) + CR with insufficient hematological recovery (CRi). Secondary endpoints were: CR duration, disease-free survival, overall survival, safety, and early mortality. Results: To date, 56 pts (50 AML, 6 high-risk MDS) with a median age of 69 years (range, 60 - 78) have been enrolled. They included 19 (34%) pts with diploid cytogenetics, 21 (38%) with complex cytogenetic abnormalities including chromosome 5 and/or 7 abnormalities, and 16 (28%) with other miscellaneous abnormalities. Fourteen (25%) pts with AML had antecedent hematological disorders (AHD) including 7 with MDS, 4 with MPN, 2 with MDS/MPN, and 1 with CLL. Four pts with AHD had received prior therapy including 5-azacytidine (n=1), decitabine (n=1), ruxolitinib + 5-azacytidine (n=1), and lenalidomide (n=1). Additionally, 10 (18%) pts had therapy-related disease with prior exposure to chemotherapy or radiation therapy. Median bone marrow blast %, and median white blood cell, hemoglobin, & platelet counts were 40% (range, 11 - 97), 3.4 x 109/L (range, 0.4 - 57), 9.4 g/dL (range, 6.8 - 13.1), and 35 x 109/L (range, 7 - 333), respectively. All 56 pts have completed >/=2 cycles of therapy and were evaluable for response; 30 (54%) achieved CR, 8 (14%) CRp, and 5 (9%) CRi for an overall response rate of 77%. Minimal residual disease (MRD) by 19 color flow-cytometry was evaluable in 35 of the 43 responders. MRD was not detectable in 24 of 35 (66%) evaluable responders. All 56 patients had baseline cytogenetics and clinically validated next generation sequencing-based analysis for the detection of somatic mutations in the coding sequence of 28 genes commonly mutated in myeloid neoplasms. Response by baseline characteristics is shown in table 1. The median number of cycles to response was 1 (1 - 4); 13 pts have required >1 cycle to achieve response. Seven (13%) pts have proceeded to allogeneic stem cell transplant. The median follow-up is 4.7 months (1.3 - 20.8). The regimen was well tolerated with the main therapy related grade >/= 3 toxicities were mucositis in 10 (18%) pts and liver enzyme elevation in 8 (14%). The median overall survival (OS) for all pts is 8.3 months. Four-week and 8-week mortality for all pts were 0 and 14%, respectively. The induction dose of vosaroxin was 90 mg/m2 in 22 pts and 70 mg/m2 in 34 pts. The lower induction dose of vosaroxin was associated with a reduced early mortality and an improved overall response rate and OS (Table 2 and Figure 1). Conclusion: Combination of vosaroxin and decitabine is effective in older pts with AML and high-risk MDS. Reponses were encouraging in the pts with TP53 and complex cytogenetics. The lower dose of vosaroxin 70 mg/m2 on days 1 and 4 is better tolerated and is associated with significantly improved outcomes. Table 1.

Background: Vosaroxin, is a first-in-class anti-cancer quinolone derived (AQD) DNA topoisomerase II inhibitor, which is not a substrate for p53 or P-glycoprotein, has limited toxicity, and is currently under evaluation for the treatment of pts with AML and high-risk MDS. Methods: Pts were eligible if they had AML or high-risk MDS (defined as having ³ 10% blasts in the bone marrow), were 60 years of age or older, and had adequate performance status (ECOG ² 2) and organ function. Pts younger than 60 who were unsuitable for standard chemotherapy were also eligible. In the phase I part of the study the first six pts received vosaroxin 90 mg/m2 daily on days 1 and 4 with decitabine 20 mg/m2 daily for 5 days. This dose was well tolerated with no dose limiting toxicity identified and pts were then enrolled on phase II at this dose and schedule. However, due to mucositis in a few subsequent pts, the induction dose of vosaroxin was reduced to 70 mg /m2, starting with pt #25. The vosaroxin dose could be maintained at 70 mg/m2 or reduced to 50 mg/m2 in consolidation cycles, which were repeated in approximately 4 to 5-week intervals for a total of up to 7 cycles. Dose adjustments and dose delays of one or both agents, were allowed based on toxicity. The primary endpoint was to determine the overall response rate including complete response (CR) + CR without platelet recovery (CRp) + CR with insufficient hematological recovery (CRi). Secondary endpoints were: CR duration, disease-free survival, overall survival, safety, and early mortality. Results: To date, 35 pts (32 AML, 3 high-risk MDS) with a median age of 71 years (range, 41-78) have been enrolled; 34 (97%) pts were older than 60 years. They included 15 (43%) pts with diploid cytogenetics, 12 (34%) with complex cytogenetic abnormalities including chromosome 5 and/or 7 abnormalities, and 8 (23%) with other miscellaneous abnormalities. 13 (37%) pts with AML had antecedent hematological disorders (AHD) including 7 (20%) with MDS, 4 (11%) with myeloproliferative neoplasm and 2 (6%) with MDS/MPN. Three pts with AHD had received prior therapy including 5-azacytidine (n=1), ruxolitinib + 5-azacytidine (n=1), and lenalidomide (n=1). Additionally, 5 (15%) pts had therapy-related disease with prior exposure to chemotherapy or radiation therapy. Median bone marrow blast %, median white blood cell, hemoglobin, & platelet counts were 40% (9-97), 4.1 x 109/L (0.4-57.0), 9.4 g/dL (6.8-11.5), and 40 x 109/L (7-333), respectively. 34 pts were evaluable for response; 17 (50%) achieved CR, 6 (18%) CRp, and 3 (9%) CRi for an overall response rate of 77%. One pt is too early for response assessment. Responses by age, cytogenetic and molecular characteristics are shown in table 1. The median follow-up is 5.1 months (range, 0.9-11.0). Pts have received a median of 2 (1-6) treatment cycles with the median number of cycles to response being 1 (1-4). Three pts have relapsed and the median duration of CR/CRp/CRi has not been reached (0.5-9.9+ months). Four (12%) pts have proceeded to allogeneic stem cell transplant (ASCT). 4-week and 8-week mortality were 0% and 14%, respectively. The regimen is well tolerated with the main grade ³ 3 toxicity being mucositis in 9 (26%) pts and liver enzyme elevation in 3 (9%). Conclusion: Combination of vosaroxin and decitabine is effective and feasible in older pts with AML and high-risk MDS. Enrollment is ongoing.

Abstract Abstract 4017 Background: Chronic myelomonocytic leukemia (CMML) is a heterogeneous disease sharing features of myelodysplastic syndromes (MDS) and myeloproliferative neoplasms (MPN). FDA approved indications for azacitidine and decitabine include CMML as subset of MDS. Fewer than 10 patients with CMML, however, were treated in each of the original studies. In this study we report our institutional experience of azacitidine treatment of CMML patients. Methods: This was a retrospective review of CMML patients who received azacitidine at Moffitt Cancer Center. The primary endpoint was determining response rate to azacitidine utilizing International Working Group 2006 criteria (IWG 2006). Secondary objectives were to assess treatment tolerance and overall survival. Descriptive statistics were used for baseline characteristics and response rates. Kaplan-Meier estimates were used for evaluation of overall survival. Results: Between July 2004 and December 2009, 35 CMML patients treated with azacitidine were identified. Table-1 summarizes baseline characteristics of those patients. Based on Dusseldorf CMML risk criteria one patient (2.9%) was low risk, 17 (48.7%), intermediate, 7 (20%) high risk and 10 (28.6%) were unknown. According to MD Anderson CMML risk model, 11 (31.4%) were low risk, 12 (34.3%) int-1, 2 (5.7%) int-2, 1 (2.9%) high risk and 9(25.7%) unknown. The median number of azacitidine cycles was 6.0 (1-34) The best response rates by IWG 2006 criteria were complete response (CR) 5 (14.3%), marrow CR 4 (11.4%), partial response (PR) 1 (2.9%), and hematological improvement (HI) 7 (20%). The overall response rate was 48.6%. The median OS was 25 month (95%CI 13.8–36.1 mo). Conclusions: In this retrospective analysis, response to azacitidine in CMML was similar to response rates reported in other MDS patients on azacitidine studies. The median overall survival is comparable to AZA-001 randomized clinical study. Disclosures: Lancet: Celgene: Research Funding. List:Celgene: Research Funding.

Abstract Abstract 1720 Background: hypomethylating agents, especially AZA, have become the reference treatment of higher risk MDS, but the median survival of about 2 years obtained with AZA remains modest, and must be further improved. In addition, if it is able to increase overall survival in MDS, AZA yields only about 30% of marrow response (including CR+PR+ mCR), Idarubicin given at conventional dose (12 mg/m2/d during 3 days) is the anthracycline of choice in the intensive chemotherapy given with cytarabine in patients with high risk MDS and, given as a single agent, induces up to 30% of complete remission (CR) in elderly AML patients. Thus, we designed a phase I/II study evaluating the safety and efficacy of 2 doses of Idarubicin combined with Azacitidine in high risk MDS patients (clinical trial NCT01305135). Methods: For this trial Azacitidine was combined with increasing doses of Idarubicin. Main Inclusion criteria were: (1) IPSS int 2 or high MDS, or CMML with WBC < 13,000/mm3 and marrow blasts > 10% or AML with 20–30% marrow blasts (corresponding to EU label for AZA) (2) Age 3 18 years (3) Performance Status (PS) <=2 (4) no prior treatment except ESAs. Patients received Azacytidine 75 mg/m2/d SC during 7 days every 4 weeks combined on day 8 of each cycle to Idarubicin 5 mg/m2 (administered by 1 hour IV infusion) in the first cohort of 10 patients, escalated to Idarubicin 10 mg/m2 IV in the second cohort of 10 patients after review of toxicity (especially hematological) of the 1st cohort by the independent DSMB r. The primary endpoint of the study was response after 6 cycles according to IWG criteria. Data were analyzed at the reference date of June, 1St 2012. Results: The 20 study patients (from 8 centers) were enrolled between Dec 2010 and Feb 2012, including 7 women and 13 men with a median age of 75 years. At inclusion, WHO classification was RCMD in 1 pt, CMML in 1 pt, RAEB-1 in 6 pts, RAEB-2 in 7 pts, AML in 3 pts and unclassified in 2 pt. Median marrow blasts were 6.5% (0–26) Karyotype (IPSS) was favorable in 7 pts, int in 3 pts and unfav in 8 pts (2 pts had cytogenetic failure). IPSS was high in all patients. PS was 0 in 28% pts, 1 in 50% and 2 in 22%. A total of 92 cycles of treatment had been administrated with a median number of 5 cycles/patient and 10 pts had received 6 or more cycles. 14 patients had terminated the study due to side effects (severe febrile pancytopenia, n=2), disease progression (n=5, after 2–10 cycles), death (disease progression, severe septic shock after Cycle 2, and unrelated coma), stable disease after 6 cycles (n=3), and patient decision (n=1). Overall 7 pt had died. 18 SAEs were reported observed in 9 patients, including 10 episodes of febrile neutropenia, 3 episodes of bleeding and 5 unrelated SAE. Of the 20 patients enrolled in the study, 19 were evaluable for response after 3 cycles, including 10/10 in the First cohort and 9/10 in the second cohort. One patient achieved CR, 2 PR, 1 mCR and 2 additional patients achieved stable disease with HI, leading to an Overall response rate of 6/19 (32%). Two patients were still on study but did not reached cycle 6. Thus, after 6 cycles, 17 patients, only could be evaluated. Among them 9/17 (53%) patients were still on study, 2 pts had died, 3 progressed, 2 had experienced sides effects and had terminated the study and 1 pt had withdrawn consent. Two patients achieved CR (including 1 already in CR at cycle 3), 2 PR and 2 additional patients achieved stable disease with HI leading to an Overall response rate of 6/17 (35%). At the time of the present analysis, none of the responder had relapsed. Conclusion: The phase I/II results presented here show that Idarubicin can be combined to Azacitidine with acceptable toxicity. Whether the azacitidine- Idarubicin combination can improve the outcome of higher risk MDS patients will be evaluated in a phase II randomized trial comparing this combination (and other combinations of azacitidine with other drugs) to azacitdine alone alone. Data of the present phase I/II trial will be updated at the meeting. Disclosures: No relevant conflicts of interest to declare.

Long Term Treatment

Abstract Abstract 175 AOP2014 is a next generation long-acting pegylated IFNa-2b, consisting predominantly of only one isoform, as opposed to other commercially available pegylated interferons. AOP2014 has a distinct pharmacokinetic and pharmacodynamic profile which may potentially allow reduced dosing frequencies compared to other pegylated IFNs. This is being expected to result in improved tolerability, better compliance, and, finally, favorable long-term treatment outcomes. AOP2014 is a designated Orphan Drug in EU for treatment of patients with PV. The maximum tolerated dose (MTD), long term safety and efficacy of AOP2014, administered subcutaneously every 14 days, are the main objectives of the study. Patients with confirmed PV diagnosis, age equal or older 18 years, both naïve and cytoreduction pre-treated are eligible. After establishing the MTD, an extended cohort of 25 additional patients was planned to be recruited. European LeukemiaNet criteria were used for response assessment. 34 patients, treated by March 31, 2012 were included into this analysis: 25 in Phase I (dose-finding) and 9 in the Phase II (cohort extension). Median time from diagnosis was 24 months (range 0–180). 12 patients (35%) were HU pre-treated (mean past duration of HU pre-treatment 39 months, mean daily HU dose 950 mg). Median number of phlebotomies in the past 3 months prior to inclusion was 1 (range 0–8), a total of 21 patients (62%) were regularly phlebotomized at least once in three months prior to study entry. 11 patients (32%) had a history of thrombotic complications. Median Hct at baseline was 42% (range 36–51). Median WBC and platelet counts were 10.6*109/l (range 3.9–20.4) and 452*109/l (range 141–1019), respectively. 17 patients (50%) had splenomegaly at baseline. The median reported treatment duration was 41 weeks (range: 1 day – 80 weeks), 11 patients completed 1 year on treatment. Doses from 50 to 540 ug every two weeks were tested, 540 ug has been concluded as MTD as the highest tested dose, since no DLTs occurred in the study. The mean administered dose (both Phase I and II patients) was 287 ug. After 28 weeks of treatment (21 evaluable patients), 71% of patients had hematological response (7 CR, 33%; 8 PR, 38%), at week 36 (19 evaluable patients) 8 patients (42%) achieved a CR and 8 patients (42%) a PR, overall response rate (ORR, CR+PR) was 84%. At week 52 (1 year; 11 evaluable patients), 5 patients (46%) had CR and 5 (46%) PR, ORR was 91%; 8 (73%) patients presented with completely normalized blood values, all evaluable patients were phlebotomy free at this timepoint. 4 patients (of 12 evaluable for this measurement, 33%) had still enlarged spleen at week 52. At week 76, 2 evaluable patients were complete responders. At week 52, 1 patient (of 9 evaluable, 11%) developed partial molecular response, at week 68 3 patients (of 7 evaluable, 43%) had partial molecular response. One patient with allelic burden of 22% at baseline developed complete molecular response at week 36 (still ongoing). Mainly grade 1 and 2 adverse events were reported. A total of 358 adverse events occurred. 27 patients (79%) suffered from drug-related adverse events. 9 patients (26%) developed serious adverse events; 4 SAEs were considered to be treatment related. 5 patients (15%) discontinued their study participation prematurely, 3 of them due to adverse events (deterioration of underlying disease and two cases of depression). Acceptable tolerability and durable clinical benefits have been demonstrated in PV patients measured as overall response rate of above 90% with CRs of 46% at one year after treatment start. Phlebotomy independence and normalization of hematological parameters could be seen in most of the patients. The study continues to recruit and collect long term follow up information. Presented data support further development of AOP2014 in PV, a Phase III study is planned to start early 2013.

Abstract Abstract 4081 Background: Carfilzomib, a novel irreversible proteasome inhibitor (PI), has demonstrated single agent activity in, and was recently FDA approved for relapsed and refractory myeloma. Panobinostat, a potent histone deacetylase inhibitor (HDACi), has been studied as a single agent and in combination with bortezomib, demonstrating promising response rates and a favorable safety profile in bortezomib-refractory patients. Our hypothesis proposed that the combination of carfilzomib and panobinostat (Car-Pan) would also be highly active, and we therefore aimed to combine these two agents for the first time. We report the initial findings from the phase I dose-escalation and expansion portions of our phase I/II trial of this novel combination regimen. Methods: The primary objectives were to determine the maximum tolerated dose (MTD) and the safety/tolerability of Car-Pan in patients with relapsed or refractory multiple myeloma. Secondary objectives included determination of the overall response rate, time to progression, progression free survival, and time to next therapy. Panobinostat was administered orally on days 1, 3, 5, 8, 10, 12 of every 28-day cycle, while carfilzomib was given intravenously over 30 minutes on days 1, 2, 8, 9, 15, and 16. Dose level 1 started carfilzomib at 20 mg/m2 with 15 mg of panobinostat, and escalated from there using a standard 3+3 schema based on dose-limiting toxicities (DLTs) occurring in cycle 1. An amendment was later introduced to allow carfilzomib to be given at 20 mg/m2for days 1 and 2 of cycle 1, followed by an increase to the full dose level for that cohort. Adverse events (AEs) were graded using the NCI-CTCAE v4, and responses were assessed with the modified International Uniform Response Criteria. Results: To date, 20 patients have been enrolled, 3 of whom are still in their first cycle, leaving 17 evaluable patients who are described herein, who have received a median of 4 cycles (range 1–8). The median age was 62 years (range 46–73), 11/17 (70%) were male, and the median number of prior regimens was 5 (range 2–15). Patients were very heavily pretreated, with 16/17 (94%) having undergone stem cell transplantation, 16/17 (94%) having prior bortezomib, including 8/17 (47%) who were bortezomib-refractory, and 17/17 (100%) having prior lenalidomide, including 12/17 (70%) who were lenalidomide-refractory. Cytogenetic abnormalities were common, including: 4 with del(17p), 4 with t(4;14), 2 with t(11;14), 9 with del(13), of whom 7 had additional mutations. Grade 1–4 AEs regardless of causality occurring in >20% of patients included anemia (14/17), thrombocytopenia (17/17), neutropenia (8/17), diarrhea (9/17), nausea/emesis (7/17), fatigue (10/17), elevated creatinine (8/17), and pneumonia (5/17). Grade ≥3 AEs regardless of causality included anemia (7/17), thrombocytopenia (10/17), neutropenia (6/17), diarrhea (2/17), nausea/emesis (1/17), fatigue (4/17), elevated creatinine (2/17), and pneumonia (4/17). An MTD has not been established, and dosing is ongoing in cohort 4, with Carfilzomib at 45mg/m2and 20 mg of Panobinostat. Of the 17 evaluable patients, the overall response rate was 35% (6/17) who achieved at least a partial response (PR); including 2 with very good PR (VGPR). In addition, one patient had a minor response, and 65% overall achieved stable disease or better. Conclusions: The combination of Carfilzomib + Panobinostat is well tolerated with a manageable side effect profile. Importantly, the combination achieves a promising response rate in a very heavily pre-treated, lenalidomide/bortezomib/high dose melphalan-refractory population, with an overall response (≥PR) rate of 35%. Updated safety and efficacy data for all patients will be presented at the meeting.

Abstract Introduction Despite therapeutic advances in multiple myeloma, disease relapse is common. Combination therapy with dexamethasone, cyclophosphamide, etoposide, and cisplatin (DCEP) has been utilized as an effective salvage regimen for over a decade, and a recent study reported that DCEP provided an overall response rate of 45.1% when used as salvage therapy in patients who had previously received novel agents (Park S, et al. 2014). Aside from hematologic toxicities, DCEP is generally well-tolerated. In fact, the toxicity profile of DCEP has been compared to high dose cyclophosphamide in the setting of stem cell mobilization and is considered less toxic than the latter. Based upon the synergy noted when proteasome inhibitors are combined with genotoxic therapy, we have combined bortezomib with DCEP in a series of relapsed myeloma patients. Herein we report our experience with the addition of bortezomib to DCEP in relapsed/refractory disease. Patients and Methods We performed a retrospective evaluation of patients with relapsed/refractory multiple myeloma treated at Emory University Hospital from October 2011 until March 2014. Patients received dexamethasone, cyclophosphamide, etoposide, and cisplatin (DCEP) at standard doses in combination with bortezomib at either a dose of 1 mg/m2 or 1.3 mg/m2 administered on Days 1 and 4 of each cycle given every 28 days. Indications for receiving V-DCEP are either cytoreduction prior to SCT (cohort 1) or as salvage therapy (cohort 2). Results Among the 51 patients (49% male and 51% female) included in analysis, the median age at the time of diagnosis is 58 years (range 30-78) and the time of treatment with V-DCEP is 62 years (range 33-79). Among patients that received V-DCEP as cytoreduction prior to SCT, median prior lines of therapy were 1 (0-8). Among the patients that received V-DCEP as salvage therapy, median number of prior lines of therapy was 3 (1-6). ISS 3 disease was seen in 70% of patients and high risk disease in 72.5% of pts (del 17p: 31%; PCL: 19%; extramedullary disease: 33%; complex CTG: 11%) and t(4;14): 6%). Median time from diagnosis to initiation of V-DCEP therapy among cohort 1 is 18 months (0-86) and among cohort 2 is 31 months (12-105) months. Median serum creatinine before C1D1 is 1.17 (0.61-6) and serum bilirubin is 0.6 (0.1-2.8). 31% of patients needed dose reductions from our standard protocol due to organ dysfunction. 47% of patients received ≥2 cycles. The median time to next cycle is 28 days (20-46) and time to next treatment after V-DCEP is 35 days (25-451) suggesting good hematologic recovery. The overall response rate (≥PR) amongst both cohorts with V-DCEP is 47.8% (40% and 51.6% overall response for cohorts 1 and 2, respectively). Figure 1 illustrates response rates. 10 patients that presented with renal insufficiency had renal response including 2 of the 5 patients on hemodialysis. While the median PFS for cohort 1, as expected has not reached, for cohort 2, it is 8 months (95% CI 5.7-10.3). At a median follow-up of 17 months, from the time of V-DCEP initiation, median OS for cohort 2 is 10 months (95% CI 5-14.9). Median overall survival for this predominantly high risk group of patients from diagnosis in cohort 1 is 78 months (95% CI 47-108) and 49 (95% CI 17-80.7) months in cohort 2, respectively. While only 1 patient with grade 2 peripheral neuropathy (PN) received V-DCEP, change from baseline existing PN was seen in 19% of patients (no grade 3/4 events). Conclusions During this era where minimizing alkylator therapy is a consideration, certain indications exist for using V-DCEP such as cytoreduction prior to SCT or as salvage therapy serving as bridge to next line of therapy. Addition of bortezomib to DCEP is deemed safe and is an effective cytoreductive regimen in the treatment of multiple myeloma. Figure 1 Figure 1.

Background: The introduction of novel agents such as proteasome inhibitors (PI) and immunomodulatory drugs (IMiDs) with and without corticosteroids has revolutionized treatment (tx) and improved survival rates for MM. IMID/PI triplets such as VRD (bortezomib, lenalidomide, dexamethasone), VTD (bortezomib, thalidomide, dexamethasone), or KRD (carfilzomib, lenalidomide, dexamethasone) are preferred inductions for transplant-eligible patients (pts). Unfortunately, the PI often has unique safety events such as peripheral neuropathy (PN) or cardiac issues that can impact the quality of life. Elotuzumab is a mAb with a dual mechanism of action (tagging MM cells and activating NK cells by binding SLAMF7). The combination of elotuzumab, lenalidomide, and dexamethasone (ERd), is active, well-tolerated, and approved by the FDA for pts with relapsed MM. In this study, we will determine the feasibility of incorporating ERd into a transplant-eligible pt population. Methods: Pts with newly diagnosed MM requiring chemotherapy planning to undergo autologous stem cell transplantation (ASCT) were enrolled. Induction of elotuzumab at 10 mg/kg was administered IV on days (D) 1, 8, 15, 22 of the 1st 2 28-day cycles and days 1, 15 of the third and fourth 28-day cycles. Lenalidomide was dosed at 25 mg orally on D 1-21 of each 28 day induction cycle. Dexamethasone was administered IV concurrent with elotuzumab (28mg orally 3-24 hours prior to infusion and 8 mg IV with elotuzumab), with 40 mg orally administered on D 8 and 22 of cycles 3 and 4. After completion of the 4 induction cycles, pts proceeded to mobilization and ASCT though pts who refused transplantation were allowed to proceed directly to consolidation and maintenance if the investigator believed the pt was deriving benefit. 70-120 days after ASCT, 4 cycles of consolidation were administered (dosing similar to cycles 3-4 of induction but with lenalidomide at 15mg). Pts then went on to maintenance with elotuzumab 20 mg/kg IV on D 1, oral lenalidomide 10mg +/- 5 mg D 1-21 and dexamethasone 28mg oral/8 mg IV prior to elotuzumab infusion were dosed in 28-day cycles for up to 24 months. The primary endpoint was the induction feasibility rate (IFR) defined as the percentage of pts successfully completing 4 cycles of induction tx with ERd and able to start ASCT. Secondary end points were complete response rate (≥nCR), overall response rate (≥PR), progression-free survival (PFS) and overall survival (OS). AEs were assessed according to CTCAE V4 and responses were assessed using the revised IMWG criteria. Results: 52 pts were enrolled: 56% male, median age 61 ys, 12% RISS III, 21% high-risk cytogenetics [17p del, t(4;14), and/or t(14;16)]. To date, 26 (50%) pts remain on active tx. 4 pts refused transplantation despite being eligible and were excluded from the IFR calculation. The IFR was 69% and the best overall response rate (ORR) was 92% (69% ≥ VGPR). With a median follow up of 20 mos, median PFS and OS for all pts were not reached. The 18 mo PFS and OS were 83% and 89% respectively. The most common AEs were fatigue (59.6%), diarrhea (42.3%) and nausea (42.3%). PN was seen in 29%, and all events were ≤ G2. There were 28 SAEs in 20 pts, including 12 tx-related SAEs. There was 1 tx-related death due to heart failure in a pt with no history of prior cardiac issues who had subsequent therapy. 29% of pts met the high-risk (HR) criteria (defined as RISS III or high risk cytogenetics) and 29% of pts were considered standard-risk (RISS I and no high-risk cytogenetics). The best ORR was 87% (67% ≥ VGPR) for HR pts and 93% (53% ≥ VGPR) for SR pts and the IFR was 57% for HR pts and 64% for SR pts. The median PFS and OS were 20.5 mos and 22.0 mos respectively for HR pts and have not been reached for SR pts. Conclusions: ERd induction, consolidation and maintenance was feasible and well tolerated in conjunction with ASCT in transplant-eligible pts. Despite high ORR for all pts, HR patients had inferior PFS and OS. This study supports the continued evaluation of this regimen in SR pts.

Statin Use

Abstract Background : Statins (HMG-CoA reductase inhibitors) prevent the synthesis of mevalonic acid and ultimately this interferes with the isoprenylation of proteins involved in the cell cycle, namely Ras, Rac, and Rho A kinases, sometimes resulting in caspase-3 dependent apoptosis. Lovastatin has been shown to have antimyeloma activity in myeloma cells (van de Donk, Leukemia, 2002) and simvastatin restores chemosensitivity to myeloma cells exhibiting cell adhesion mediated drug resistance (Schmidmaier, Blood, 2004). Simvastatin when added to bortezomib or bendamustine in 6 patients with relapsed myeloma improved responses (Schmidmaier, EJH, 2007). Because autologous hematopoietic stem cell transplantation (HSCT) following high-dose melphalan is a standard treatment and statins may serve as sensitizing agents, we hypothesized that statin use at the time of autologous HSCT may increase the response rate to transplant, improve progression free survival (PFS), and prolong overall survival (OS). Methods : 146 patients with MM underwent autologous HSCT after melphalan 200mg/m2 at Ohio State University between June 1999 and December 2006. We reviewed their records and divided the patients into those that received (n=28) or did not receive (n=118) statins (≥ 20mg/day) for at least one month before and after transplant. Response was assessed according to the International Myeloma Working Group (IMWG) uniform response criteria (Durie BG et al. 2006). Results : The median age of the study population was 58 years (range 35–74yrs) with 86 male and 58 female patients. The two groups had similar baseline characteristics including age, serum cholesterol, international stage, disease status at the time of transplantation, number of prior therapies, and percentage of patients with high-risk cytogenetics (defined by the presence of t[4;14], t[14;16], deletion 17p, karyotypic del 13, del 13q w/14q32 rearrangement, or any tetrasomy). Stem cell mobilization in patients using statins yielded a mean of 8.3 x 106 CD34+ cells/kg versus 6.5 in patients not taking statins (p=0.4). The rate of complete response (CR) plus very good partial response (VGPR) in patients using statins (43%) was comparable to the CR + VGPR rate (45%) in patients not using statins (p=0.84). However the overall response rate (CR + VGPR + PR) was higher in the statin group (93% vs. 78%; p=0.07). In a subset analysis of patients with high-risk cytogenetics, the overall response rate in the statin group (n=5) was 100% versus 78% for non-statin group (n=14). Median overall survival (OS) for the statin vs. non-statin groups were 25.7 and 22 months respectively (P 0.65), and the progression free survivals were 19.5 and 14.8 months respectively (p=0.97). Three year PFS in the statin versus no statin groups were 32% and 30% respectively. No differences in terms of hepatic toxicity, myositis, infectious complications, and fatal cardiovascular events between groups were noted. Conclusion: Patients using statins at the time of transplant showed a trend for a better overall response rate (93% vs. 78%; p=0.07) that did not translate to improved PFS or OS.

Background Patients with locally advanced, recurrent or metastatic solitary fibrous tumour are often treated with bevacizumab and temozolomide based on the clinical efficacy reported in a case series of 14 patients. Given the rarity of solitary fibrous tumour, large trials are not feasible. We report the efficacy of this regimen based on a population-based analysis. Methods This was a population-based retrospective, multi-centre analysis using patient data from a provincial cancer registry and treatment database. Cases from June 2006 through October 2016 were identified for patients receiving bevacizumab and temozolomide for locally advanced, recurrent or metastatic solitary fibrous tumour or hemangiopericytoma, which is sometimes used to describe tumours arising from the meninges. The primary outcome was overall response rate. Secondary outcomes included time to response, progression free survival and overall survival estimated using the Kaplan–Meier method. Results Fourteen patients were identified: median age 59 (range 44–70), male 78.6%. Diagnoses were solitary fibrous tumour in 10 (71.4%) and hemangiopericytoma in four (28.6%), with metastatic disease in 10 (72.7%) patients. The most common primary sites were meninges in four (28.6%) and pelvis in three (21.4%) patients. The median follow-up was 15.5 months, with median treatment of four months. Overall response rate was 21.4% (no complete response, 3 partial response), with median time to response of four months. Median progression free survival, six-month progression free survival and overall survival were 17 months, 65.0%, and 45 months, respectively. Conclusions Efficacy of bevacizumab and temozolomide in solitary fibrous tumour appeared to be similar to that previously reported. Our findings confirmed that bevacizumab and temozolomide is an effective and tolerated treatment for this patient population.
