Abstract Abstract 2042 Background: The optimal pre-transplant induction therapy for newly diagnosed MM remains to be determined. Combinations of lenalidomide, bortezomib, and dexamethasone result in high response rates with acceptable toxicity in the majority of patients. The most commonly utilized regimens in the U.S. are lenalidomide and dexamethasone (RD); bortezomib and dexamethasone (VD); lenalidomide, bortezomib, and dexamethasone (VRD); and thalidomide and dexamethasone (TD). We sought to determine whether any of the common initial regimens is a superior first choice. Methods: This retrospective single center study examined MM patients < 70 who underwent their initial ASCT between 7/1/2008 to 6/30/2011. A chart review was conducted using the outpatient electronic medical record. Data was gathered on disease characteristics, induction regimens, disease response, and clinical course after ASCT. The primary outcome measures were progression-free survival (PFS), overall survival (OS), and event-free survival (EFS), all measured from day 0 of ASCT. The secondary outcome measures were number of distinct induction therapy regimens, time from start of induction therapy to ASCT, and disease response immediately prior to ASCT. Disease response was grouped as either ≥Very Good Partial Response (VGPR) or <VGPR. The observation period ended on 6/30/2012. Results: A total of 174 patients were included in the analysis. The initial regimen was RD for 80 patients (46%), VD for 43 patients (25%) and VRD for 30 patients (17%). Other regimens (mostly thalidomide-based) accounted for the remaining 12%. The TD regimen was inferior as initial therapy in terms of all outcome endpoints. The primary analysis, therefore, compared RD to VD to VRD. The baseline characteristics for these groups of patients (including gender, stage at diagnosis, serum creatinine at diagnosis) were similar for RD and VRD, but the VD group had more subjects with higher stage (p=0.018) and creatinine > 2 at diagnosis (p<0.001). Use of maintenance therapy after ASCT, usually with lenalidomide, was different between the groups (p<0.001), with more frequent use for patients who received VRD or RD as initial therapy (73% and 64% respectively) than for patients who received VD (26%). The frequency of changes in induction therapy was similar across groups (received > 1 induction regimen: RD 29%, VD 26%, VRD 17%, p=NS). The primary reason for a change in regimen was lack of response rather than toxicity. Response rates immediately before ASCT were not significantly different among regimens (≥VGPR: RD 51%, VD 63%, VRD 73%, p=0.08). EFS was similar for patients treated with the RD, VD, and VRD (EFS at 2 yr post-ASCT: RD 56%, VD 48%, VRD 70%, p=NS). With a median follow-up of 26.3 months after ASCT, there is no significant difference in PFS or OS (OS at 2 yr post-ASCT: RD 90%, VD 86%, VRD 96%). Conclusions: We compared three commonly used regimens for initial treatment of MM in the transplant eligible population to determine if one combination resulted in a better outcome than the others after ASCT. Although there was a trend towards higher pre-ASCT responses with VRD induction therapy, with approximately 2 years of median follow-up, survival was not significantly different when based on choice of initial therapy. These data support that in the current era of highly active induction regimens, choice among them can be made considering such factors as disease manifestations, potential toxicity and drug administration rather than response rates and survival differences. Longer follow-up of these patients as well as future prospective analyses will further clarify these results.

Abstract Abstract 2058 Poster Board II-35 Therapy of AML for elderly pts (≥ 60 yrs) remains challenging with low response rates, short durability of responses, and high toxicity rates following conventional therapy with standard-dose ara-C/anthracycline combinations. Clofarabine is a novel deoxyadenosine nucleoside analogue with single agent activity in frontline AML for older pts with ≥ 1 unfavorable prognostic factors. We have recently reported results of a randomized study suggesting higher response rates and comparable safety profile with the combination of clofarabine plus low-dose cytarabine over clofarabine alone. We have designed the current study of clofarabine plus low-dose cytarabine induction followed by consolidation with clofarabine plus low-dose cytarabine alternating with decitabine to maintain high response rates and improve disease-free survival based on the following hypotheses: 1) to extend duration of therapy by administering lower doses of the agents; and 2) to provide multiple drugs with different mechanisms of action to decrease risk of resistance. Pts were eligible if ≥ 60 yrs of age with newly diagnosed AML. Pts were excluded for ECOG PS > 2, creatinine > 1.5 mg/dL, cardiac ejection fraction < 40%, and prior therapy with clofarabine or decitabine. Induction therapy consisted of clofarabine 20mg/m2 i.v daily × 5 days plus cytarabine 20mg s.c. twice daily × 10 days in a laminar air flow room. Responding pts could receive up to 17 courses of consolidation therapy of clofarabine plus cytarabine (over 3 and 7 days, respectively) during consolidation courses 1-2, 6-8, 12-14) alternating with decitabine 20mg/m2 i.v. daily for 5 days during courses 3-5, 9-11, and 15-17. All pts received antibiotic prophylaxis with levofloxacin, valacyclovir and itraconazole (or equivalent). Forty pts have been enrolled with a median age of 70 yrs (range 60-80) of whom 22 (55%) had secondary AML (antecedent hematologic disorder in 11 pts). Two pts had received previous azacitidine for MDS. Fourteen pts (35%) had abnormal cytogenetics of whom 10 (25%) had monosomy 5, 7, or both. Four patients (10%) had a FLT3/ITD mutation. Of the 34 pts evaluable for response, 20 (59%) achieved CR and 2 (6%) CRp for an OR rate of 65%. Only 2 pts required 2 courses to CR. The OR rate for patients with diploid versus abnormal cytogenetics was 80% vs 50%; for pts with prior MDS versus no prior MDS 76% and 50%; and 75% for patients with FLT3 mutation. The median time to CR/CRp was 38 days (range 27-103). With a median follow up of 3.5 months (range 0.7-8.1), 2 pts relapsed (CR duration of 3.3 and 4.2 months, respectively); responses are ongoing in the remainder. Three pts (9%) died during induction therapy (one during re-induction) before a response could be established. The median number of consolidation cycles received by pts in CR was 3 (range 1-5). Most toxicities were ≤ grade 2 and included nausea/vomiting, diarrhea, rash, headache and mucositis. Six pts developed grade 3 elevations in serum transaminases which resolved at the end of induction therapy. Myelosuppression and neutropenic fever were common, but prolonged myelosuppression was rare. In conclusion, clofarabine plus low-dose cytarabine achieves high response rates with a manageable toxicity profile and low induction mortality in elderly pts with previously untreated AML. Time-to-event parameters will be provided with more extensive follow up. Disclosures: Off Label Use: Clofarabine and Decitabine in AML. Kantarjian:Genzyme: Consultancy, Research Funding.

Abstract Abstract 207 Background: Results from the phase 3, international, randomized ENESTnd trial have demonstrated the superior efficacy of nilotinib over imatinib with significantly higher rates of major molecular response (MMR), complete cytogenetic response (CCyR), and with significantly lower rates of progression to AP/BC on treatment. Here, we present data with a median follow-up of 18 months. Methods: 846 CML-CP patients were randomized to nilotinib 300 mg twice daily (bid) (n=282), nilotinib 400 mg bid (n=281), and imatinib 400 mg once daily (n=283). Primary endpoint was MMR (≤ 0.1% BCR-ABLIS) rate “at” 12 months, as previously presented. Key secondary endpoint was durable MMR at 24 months. Other endpoints assessed at 24 months include progression to AP/BC (with and without clonal evolution), event-free survival, progression-free survival, and overall survival (OS). Results: With a median follow-up of 18 months, the overall best MMR rate was superior for nilotinib 300 mg bid (66%, P < .0001) and nilotinib 400 mg bid (62%, P < .0001) compared with imatinib (40%). Superior rates of MMR were observed in both nilotinib arms compared with the imatinib arm across all Sokal risk groups (Table). The overall best rate of BCR-ABLIS ≤ 0.0032% (equivalent to complete molecular response, CMR) was superior for nilotinib 300 mg bid (21%, P < .0001) and nilotinib 400 mg bid (17%, P < .0001) compared with imatinib (6%). The overall best CCyR rate was superior for nilotinib 300 mg bid (85%, P < .001) and nilotinib 400 mg bid (82%, P=.017) compared with imatinib (74%). The superior efficacy of nilotinib was further demonstrated using the 2009 European LeukemiaNet (ELN) 12-month milestone in which fewer patients had suboptimal response or treatment failure on nilotinib 300 mg bid (2%, 3%) and nilotinib 400 mg bid (2%, 2%) vs imatinib (11%, 8%). Rates of progression to AP/BC on treatment were significantly lower for nilotinib 300 mg bid (0.7%, P=.006) and nilotinib 400 mg bid (0.4%, P=.003) compared with imatinib (4.2%). The rate of progression on treatment was also significantly lower for nilotinib when including clonal evolution as a criteria for progression (Table). There were fewer CML-related deaths on nilotinib 300 mg bid (n=2), and 400 mg bid (n=1) vs imatinib (n=8). Estimated OS rate (including data from follow-up after discontinuation) at 18 months was higher for nilotinib 300 mg bid (98.5%, P=.28) and nilotinib 400 mg bid (99.3%, P=.03) vs imatinib (96.9%). Both drugs were well-tolerated. Discontinuations due to adverse events or laboratory abnormalities were lowest for nilotinib 300 mg bid (7%) compared with nilotinib 400 mg bid (12%) and imatinib (9%). With longer follow up there has been minimal change in the occurrence of AEs. Minimum 24-month follow-up data for all patients will be presented. Conclusions: With longer follow-up, nilotinib was associated with a significantly lower rate of progression to AP/BC on treatment and lower rates of suboptimal response or treatment failure vs imatinib. Nilotinib resulted in fewer CML-related deaths and a higher OS rate vs imatinib. Nilotinib induced superior rates of MMR, CMR, and CCyR vs imatinib in patients with newly diagnosed CML-CP. Taken together, these data support nilotinib as a new standard of care for patients with newly diagnosed CML.

Abstract Abstract 336 Standard therapy (e.g. “3+7”) of newly diagnosed older pts (≥ 60 yrs) with AML is characterized by low response rates, short response durations, and substantial toxicities. New approaches are therefore actively explored in clinical trials. Clofarabine is a second generation deoxyadenosine nucleoside analogue with activity in older pts with frontline AML and presence of unfavorable prognostic factors. In our experience, the combination of clofarabine with low-dose cytarabine achieved higher response rates at no increase of toxicity compared with clofarabine alone (Faderl S et al. Blood 2008). Based on the initial experience, we have designed a combination of lower-dose clofarabine plus low-dose cytarabine induction followed by a prolonged consolidation of these drugs alternating with decitabine to improve survival and maintain the high response rates from the earlier study. Pts were eligible if ≥ 60 yrs of age with newly diagnosed AML. Pts were excluded for ECOG PS > 2, creatinine > 1.5 mg/dL, cardiac ejection fraction < 40%, and prior therapy with clofarabine or decitabine. Induction therapy consisted of clofarabine 20mg/m2 i.v daily × 5 days plus cytarabine 20mg s.c. twice daily × 10 days. Responding pts could receive up to 17 courses of consolidation therapy of clofarabine plus cytarabine (over 3 and 7 days, respectively) during courses 1–2, 6–8, 12–14 alternating with decitabine 20mg/m2 i.v. daily for 5 days during courses 3–5, 9–11, and 15–17. All pts received antibiotic prophylaxis with levofloxacin, valacyclovir and itraconazole (or equivalent). Fifty-nine pts have been accrued with a median age of 70 yrs (range 60–81), of whom 17 pts (29%) were ≥ 75 yrs. Eleven pts (19%) had a PS of 2. Seven pts (12%) had a WBC of > 20,000/mcl at diagnosis. Thirty pts (51%) had abnormal cytogenetics. Molecular profile: FLT3/ITD 5 pts (9%), FLT3/D835 2 (4), NPM1 6 (13), Ras 2 (4). Thirteen pts (22%) had prior MDS (4 pts prior azacitidine; 2 pts prior lenalidomide) and 17 pts (29%) had secondary AML (Hx of prior chemo and/or XRT). Of 57 pts evaluable for response, 35 (61%) achieved CR and 4 (7%) CRp for an ORR of 68%. Six pts (11%) required more than one course to response. The ORR for pts with diploid vs abnormal cytogenetics was 79% vs 57%; for pts with prior MDS 46% vs 82% for pts with neither MDS nor secondary AML. All 7 pts with a FLT3 mutation responded. With a median follow up of 11.6 months (1.1-20.2+), 16 pts relapsed. Responses (CR) are ongoing in 19 pts. Median CR duration is 14.1 mos (1.8-16.4). Six pts (10%) died on study. Only one pt suffered an early death ≤ 28 days from induction (C1D26). Deaths were due to myelosuppression-associated infectious complications. Median overall survival for all 59 pts was 18.1 mos (0.8-20.2+). Median overall survival for responding patients has not been reached. The median number of consolidation cycles received by pts in CR/CRp was 4 (0-14). Fifteen of these pts have so far received at least 6 consolidation cycles. Most toxicities were ≤ grade 2 and included rash (64%), nausea (61%), transaminase elevations (58%), bilirubinemia (51%), diarrhea (32%), mucositis, creatinine evelations, and headache (12% each). Among toxicities > grade 2, transaminase elevations (14%) and bilirubinemia (5%) were most frequent. One pt (65 yr old female) experienced renal failure and pulmonary edema shortly following start of the induction. Myelosuppression and neutropenic fever were common, but prolonged myelosuppression in responders was rare. In summary, clofarabine plus low-dose cytarabine achieves high response rates with a manageable toxicity profile and low induction mortality in pts ≥ age 60 with previously untreated AML. Longer follow up and comparisons with conventional therapy will help establish whether or not this combination also has a survival advantage.

Abstract Abstract 1550 Background: Clofarabine is a second generation nucleoside analogue with activity in adults with AML. A recent randomized phase III study in AML relapse showed higher response rates and better event-free survival with the combination of clofarabine and cytarabine (CA) compared to cytarabine alone. We have also reported the feasibility and safety of the addition of idarubicin to CA (CIA) in a previous phase I and II study. To explore this combination further, we conducted a phase II study of CIA in pts</= 60 years with previously untreated AML. Patients and Methods: Patients (Pts) were eligible if they were </=60 yrs of age with newly diagnosed AML. Pts were excluded for ECOG PS > 2, cardiac ejection fraction < 45%, or active and uncontrolled infection. For the first 30 pts, induction therapy consisted of Clofarabine 22.5 mg/m2 iv daily (days 1–5), Idarubicin 6 mg/m2 daily (days 1–3), and Cytarabine 0.75 g/m2 daily (days 1–5). From pt 31 onward, induction doses were amended to Clofarabine 20 mg/m2 × 5, Idarubicin 10 mg/m2 × 3, and Cytarabine 1 g/m2 × 5. Pts who have not achieved a complete remission following the induction could receive one re-induction course. Pts in CR or CRp continued with up to 6 consolidation cycles with Clofarabine 22.5 mg/m2 × 3, Idarubicin 6 mg/m2 (days 1–2), and Cytarabine 0.75 g/m2 × 3, subsequently amended to Clofarabine 15 mg/m2 × 3, Idarubicin 8 mg/m2 × 2, and Cytarabine 0.75 g/m2 × 3. Supportive care was standard. Pts ≥ 50 yrs were admitted to a laminar air flow room for the duration of the induction. Results: From April 2010 until August 2011, 51 pts have been accrued with a median age of 49 yrs (range 19–59): 33 pts (65%) with de novo AML and 18 pts (35%) with secondary AML (18 related to MDS, 7 related to therapy). Three pts (5%) had a PS of 2. Median WBC at diagnosis was 3.4 × 109/L (0.6-92.3). Thirty-three (65%) pts had abnormal cytogenetics (21/33[64%] poor risk and 5/33 [15%] intermediate risk). Molecular profile: 6 pts (11%) had FLT3/ITD, 3 pts (6%) CEBPA, and 8 pts (16%) NPM1 mutations. Thirty-five pts (69%) achieved CR and 1 (2%) CRp for an overall response rate (ORR) of 71%. 61% pts (31/51) achieved CR following one induction cycle. 18% (9/51) pts required a re-induction and 44% (4/9) of them responded after the re-induction. Responding pts received a median of 2 courses (1–8) courses. With a median follow-up of 23 weeks (3–36+) median remission duration has not been reached with a 1-yr remission probability of 85%. Ten pts (19%) died on study including 2 (4%) who died < 28 days from treatment start (one from septic shock and multi-organ failure, and one from Steven Johnson syndrome). Median overall survival (OS) for responding pts has not been reached (2–36 weeks). One-yr survival probability is 65%. Sixteen pts (31%) proceeded with an allogenic stem cell transplant in CR1. Most toxicities were </= grade 2 and included rash (41 %), nausea (29%), diarrhea (23%), elevated transaminases (21%), and elevated bilirubin (17%). Toxicities > grade 2 included elevated bilirubin (4%), hypokalemia (4%), cellulitis (4%) and seizure (1%). Myelosuppression was ubiquitous but prolonged myelosuppression > 42 days was infrequent. 76 % (39/51) pts had neutropenic fever. Conclusion: Clofarabine, Idarubicin and Cytarabine achieve a response rate of 71% in patients </=60 yrs with previously untreated AML. Induction mortality was low and the toxicity profile was expected and manageable. Longer follow up and comparisons with standard induction therapy will be needed to further assess the role of this combination in AML therapy.

Abstract Abstract 2800 Background: Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic stem cell disorder categorized as a mixed myeloproliferative/myelodysplastic disorder in the World Health Organization classification system. Diagnostic criteria include a persistent peripheral blood monocytosis >1 × 109/L and bone marrow dysplasia. Our recent review of SEER Medicare data (ASH 2011 abstract 2784) demonstrated that CMML has a shorter overall survival (OS) and more frequent progression to acute myeloid leukemia (AML), compared to myelodysplastic syndromes (MDS). Due to the heterogeneity of this disease and its differences from MDS, efforts to identify prognostic factors have been ongoing. The MD Anderson prognostic score was previously validated, but was derived from patients treated prior to the availability of the hypomethylating agents (HMAs) azacitidine and decitabine. HMAs have now emerged as standard therapy, with reported response rates of 37–69%, but their impact on survival and AML transformation is unclear. The OS of CMML patients has been reported at 12–18 months and transformation rates have varied between 15–52%. We reviewed our own single-center experience with CMML over the past 12 years. Methods: We conducted a retrospective review of CMML patients evaluated at the University of Maryland Greenebaum Cancer Center between January 2000 and August 2012. Patient and disease characteristics, treatments, complications, progression to AML, and OS were recorded and analyzed. Descriptive statistics were used for baseline characteristics and Kaplan-Meier analysis was performed for all time-to-event data. Statistical analyses were performed using SPSS version 20.0. Results: We identified 35 patients with CMML, 71% were male and 71% white, with a median age of 69 (range 34–86) years; 75% had <10% bone marrow (BM) blasts and 68% had low-risk cytogenetic findings (normal karyotype or -Y). Most patients treated prior to 2005 received hydroxyurea and/or erythropoiesis-stimulating agents or were enrolled on clinical trials, while patients treated since 2005 received HMAs as primary therapy. The median OS of the entire cohort was 19.5 months, with 49% of patients progressing to AML with a median time to progression (TTP) of 16.9 months. Of the entire cohort, patients with <10% and ≥10% BM blasts had an estimated OS of 19.4 and 11.7 months respectively (p=.021). Patients with low-, intermediate-, and high-risk (complex karyotype, +8, or chromosome 7 abnormalities) cytogenetic findings had an estimated OS of 23.3, 16.5, and 12.0 months respectively (p<0.001). Twenty-two patients received HMAs. Their estimated OS was 16.5 months, compared to 23.0 months for patients who did not receive HMAs (p =.683); 50% of patients treated with HMAs had known progression to AML, with TTP varying from 3–28 months. AML-free-survival was 16 months in patients receiving HMAs, compared to 14 months in patients not treated with HMAs (p=0.960). The majority of patients receiving HMA therapy (63%) were treated with ≥ 6 cycles; 57% of these patients transformed to AML despite initial response, often in a sudden and unpredictable manner. Conclusions: Published trials using HMAs in CMML have been limited by small patient numbers, short median follow-up, and paucity of data on AML transformation. Our study had a median follow-up period of 41.1 months. We found a high rate of AML transformation and short OS even in patients who received HMAs. HMA treatment had no statistically significant impact on AML-free survival or OS. Although the results may be confounded by some selection bias, treatment with HMAs was largely based on the date of diagnosis rather than prognostic variables or performance status. Therefore, the favorable response rates previously reported with these agents, and also seen in our patients, do not appear to translate into an OS or AML-free-survival advantage. Our study underscores the continued need for novel agents and the need to prioritize clinical trials for this group of patients. Additionally, based on our data, early bone marrow transplantation should be strongly considered for CMML patients when feasible.

Abstract Background: Peripheral T-Cell lymphomas (PTCLs) constitute approximately 10% of lymphoid malignancies and consist of several distinct entities based on pathologic and clinical characteristics. With the exception of a few subtypes (e.g., ALK-positive anaplastic large cell lymphoma (ALCL) and some primary cutaneous or leukemic forms of PTCL), a majority of PTCLs are aggressive as characterized by poor treatment response, rapid disease progression and poor overall survival. We have shown that landmark timepoints of event-free survival after diagnosis can stratify subsequent overall survival (OS) in diffuse large B-cell and follicular lymphoma. Here we evaluate this approach in newly diagnosed aggressive PTCLs treated with anthracyline-based or related chemotherapy. Methods. Newly diagnosed PTCL patients were prospectively enrolled in the University of Iowa/Mayo Clinic Lymphoma SPORE Molecular Epidemiology Resource (MER) from 2002-2012. Clinical data were abstracted from medical records using a standard protocol. For this analysis, we included patients receiving anthracycline-based or other multiagent chemotherapy for the following PTCL subtypes: ALK-negative ALCL (N=24); angioimmunoblastic T-cell lymphoma (AITL, N=34); PTCL, not otherwise specified (NOS; N=60); enteropathy-associated T-cell lymphoma (EATL, N=8); extranodal NK/T-cell lymphoma, nasal type (ENKTL, N=11); and hepatosplenic T-cell lymphoma (HSTCL, N=1). Patients were prospectively followed, and event-free survival (EFS) was defined as time from diagnosis to progression, re-treatment, or death due to any cause. Landmark EFS timepoints were assessed at 12 (EFS12) and 24 (EFS24) months after the date of diagnosis. Subsequent OS was defined as time from a specific endpoint (diagnosis, event or EFS landmark). Replication was performed in a population-based cohort of T-cell lymphomas diagnosed from 2000-2009 from the Swedish Lymphoma Registry. Results. 138 eligible patients were enrolled in the MER from 2002-2012, the median age at diagnosis was 58 years (range, 19-88), 66% were male, 73% had Stage III-IV disease, and 33% had IPI 0-1. At a median follow-up of 47 months (range 11-120), 87 patients (63%) had an event and 70 patients (51%) had died. From diagnosis, only 60 patients were event-free at 12 months (EFS12 45%). Patients who failed to achieve EFS12 had a poor subsequent OS from event (median OS = 6.8 months, 95% CI: 5.3-14.0, figure 1). In contrast, patients who achieved EFS12 had a favorable subsequent OS (median unreached, figure 2). Of the 427 eligible patients in the Swedish registry, the median age at diagnosis was 66 years (range, 18-88), 63% were male, 68% had Stage III-IV disease, and 25% had IPI 0-1. PTCL subtypes were: ALK-negative ALCL (N=89); AITL (N=80); PTCL, NOS (N=183); EATL (N=44); ENKTL (N=24); and HSTCL (N=7). At a median follow-up of 86 months (range 40-158), 333 patients (79%) had an event and 316 patients (74%) had died. From diagnosis, 183 patients were event-free at 12 months (EFS12 44%). Similar to the MER cohort, Swedish patients failing EFS12 had poor subsequent survival (median OS = 3.7 months, 95% CI: 2.9-5.3, figure 1). Swedish patients achieving EFS12 had a favorable subsequent OS (median OS = 89 months, figure 2). Similar results were obtained when conducting landmark analysis at 24 months after diagnosis (EFS24). Conclusion. Relapse and re-treatment events within the first 12 months of diagnosis are associated with very poor OS in PTCL treated with anthracyclines or related chemotherapy, while patients achieving EFS12 have encouraging subsequent OS. Stratifying patients into prognostically distinct subsets using EFS12 may help focus biologic and biomarker studies. EFS12 has potential as an early endpoint for studies of newly diagnosed PTCL. Further investigation of determinants related to post-EFS12 survival is needed. Disclosures Maurer: Kite Pharma: Research Funding. Cerhan:Kite Pharma: Research Funding.

Background. The TT approach has significantly improved the outcome of multiple myeloma (MM) by combining new drugs with a regimen that comprises induction, tandem autologous stem cell transplantation (ASCT), consolidation and maintenance. However, a group of 15% of patients with high risk multiple myeloma (HRMM) have derived little benefit despite similar response rates to induction chemotherapy and ASCT when compared to low risk MM. The poor outcome of HRMM is explained by early relapse post ASCT resulting in a short progression free survival (PFS) with only 15-20% of patients surviving long-term. Daratumumab (Dara) is a human IgG1k anti-CD38 monoclonal antibody that has shown favorable results in early single-arm studies and more recently in phase III studies for relapsed/refractory and newly diagnosed MM. In TT7, we introduced Dara during all phases of therapy, including immune consolidation early post ASCT, to improve responses rate and PFS in HRMM. Methods. Patients had newly diagnosed HRMM as defined by high risk cytogenetic abnormalities, presence of extramedullary disease, >3 focal lesions on CT-PET, elevated LDH due to MM, or ISS II/III with cytogenetic abnormality. Dara (16mg/kgx1) was added to induction with KTD-PACE (carfilzomib, thalidomide, dexamethasone; and four-day continuous infusions of cisplatin, doxorubicin, cyclophosphamide, etoposide). Conditioning for tandem autologous stem cell transplantation (ASCT) was with fractionated melphalan (50mg/m2x4) (fMEL) based on prior observations that patients with adverse cytogenetics fare better with fMEL rather than single high dose MEL200mg/m2.In the inter tandem ASCT period immunological consolidation with Dara (16mg/kg) alone for 2 doses was followed by Dara (16mg/kg) on day 1 combined with K (36mg/m2) and D (20mg) weekly for 2 cycles. DaraKD was administered to avoid treatment free periods allowing for myeloma regrowth. The 2nd ASCT was followed by further immunological consolidation with Dara (16mg/k) for 2 doses, and maintenance therapy for 3 yrs with 3-months block of alternating Dara-KD (dara 16mg/kg day 1; K 36mg/m2 and dex 20mg weekly) and Dara-lenalidomide (R)D (dara 16mg/kg day 1; R 15mg day 1-21 q28 and D 20mg weekly). Results. TT7 enrolled 43 patients thus far. The median follow-up was 11 months (range: 1-22). The median age was 61 yrs (range 44-73). Sixteen patients were ≥65 yrs (37.2%). A mean of 29.4x106 CD34+ cells/kg (range: 4.6-86.4) were collected. 36 patients completed ASCT #1 (83.7%) and 18 (41.9%) ASCT #2, whilst 14 patients have proceeded to the maintenance phase. R-ISS II/III or metaphase cytogenetic abnormalities were present in 85.1 and 58.1% of patients, respectively. Elevated LDH or >3FL on CT-PET were noted in 30 and 41.8%. The 1-yr cumulative incidence estimates for reaching VGPR and PR were 87 and 83%, respectively. A CR or sCR was achieved in 68 and 46%. The 1-yr estimates of PFS and OS were 91.6 and 87.2%. 40 subjects are alive, whilst 5 progressed on study therapy and 3 subsequently died. 38 patients are progression free at the time of reporting. Dara was well-tolerated and no subjects discontinued therapy due to dara-related side effects. The CR and sCR rates compared favorably to the predecessor HRMM TT5 protocol where CR and sCR rates were 59 and 27%. Conclusion. The early results of TT7 point to increased response rates of HRMM to a dara-based TT regimen with especially higher rates of CR and sCR. Longer follow-up is required to determine if these early results translate into superior PFS and OS.

Abstract Background: Autologous stem cell transplantation (SCT) improves survival in patients (pts) with multiple myeloma (MM). We have previously demonstrated that the degree of response at transplant does not impact on the outcome of transplant. However, newer induction regimens such as thalidomide and dexamethasone (Thal-Dex) result in higher response rates compared to previously used regimens such as single agent dexamethasone or vincristine, doxorubicin, and dexamethasone (VAD). We examined the outcome of SCT following three different induction therapies for newly diagnosed MM, namely VAD, single agent Dex, and Thal-Dex. Patients and Methods: 340 patients with MM who received their SCT within 12 mos of diagnosis (median 5.8, range 3–12) were studied. Patients receiving more than one induction therapy as well as those in whom thalidomide was added to dexamethasone for lack of response were excluded from the analysis. There were 105 pts in the VAD group, 140 in the Dex group and 95 in the Thal-Dex group. Responses were defined using standard criteria. Results: The study cohort consisted of 209 males (59%), with a median age of 57 years (range 30–76) at transplant. Baseline characteristics were similar in the 3 groups, except for lower age in the VAD group (median 55.8) compared to Dex (59.6) and Thal Dex (57.4) and shorter time to transplant in the Dex group (5.4 m) compared to VAD (6.4) and Thal Dex (5.9). Markers of disease activity pre-transplant, including B2M and marrow plasma cell percentage were higher in the Dex group compared to either VAD or Thal Dex. The proportion of patients with any response to induction therapy was lower in the Dex group compared to the other two. All pts in the Dex and the Thal-Dex groups received melphalan only conditioning compared to 70% in the VAD group, the rest receiving Melphalan/TBI. An objective response was achieved after SCT in 96%, 97%, and 98% of pts in the VAD, Dex and Thal-Dex groups respectively (P=0.8). A complete response to SCT was seen in 49% of patients in VAD group, 45% among those in the Dex group and 38% among those in the Thal Dex group (P=0.38). There was no difference in the median progression free survival after transplant (P=0.21) or overall survival from diagnosis (P=.34) between the three groups. The proportion free from progression at 2 years post transplant was 54%, 55% and 46% for Dex, VAD and Thal-Dex respectively. The proportion surviving at 4 years from diagnosis was 64%, 65.4% and 72% respectively for the three groups. Conclusion: We did not observe any difference in the response rates including complete responses to SCT in the three groups with nearly all pts in each group achieving a response. The progression free survival and overall survival appear to be comparable between the three groups. The results from initial therapy cannot be compared between the three regimens since the study population is restricted to patients reaching stem cell transplant. Within the limits of the study, there does not appear to be any long term impact of the initial therapy for the patients going onto an early stem cell transplant. Figure Figure

Abstract Abstract 2917 Background: The European LeukemiaNet MDS (EUMDS) registry is designed to collect information about the demographics and disease-management of newly diagnosed low-risk and intermediate-1 risk MDS patients. From April 2008 until July 2010, 828 patients have been registered in eleven participating countries through a web-based reporting system. Objectives: This report describes the disease-management of the first 800 registered patients, including transfusion-related issues like secondary iron overload and its treatment. Results: 159 of 800 patients (20%) started MDS specific treatment within three months before registration; this percentage increased to 50% at 18 months of follow-up. Most patients received erythroid-stimulating agents (ESA), like erythropoietin (Table 1). In patients with a clinical indication for ESA, the percentage of transfusion-independency was similar to the transfusion-independent group without indication for ESA at 18 months of follow-up (Table 1). Overall, 27% of the patients received blood transfusions at registration. This percentage remained stable during follow-up, probably due to the therapeutic effect of ESA (Table 1). The number of units transfused, per 6 months, in these patients increased from 5 to 13 units at 18 months of follow-up, with a mean pre-transfusion Hb level of 7.6 g/dL. The serum ferritin levels of the transfusion-dependent patients at registration were available in 159 patients. The serum ferritin level at registration was ≥2000 μg/L in 4% of the patients who received a mean number of 10 units (SD 7). This increased to 28% of the patients who received a mean number of 20 units (SD 11) at 18 months of follow-up. The percentage of patients on iron chelation therapy increased from 1% to 9% during follow-up (Table 1). In these patients the mean serum ferritin levels remained stable: 1913 μg/L (SD 1183) at registration and 1626 μg/L (SD 1232) at 18 months of follow-up. In contrast, transfusion-dependent patients not treated with iron chelation or ESA had increasing ferritin levels, with a mean ferritin of 630 μg/L (SD 597) at registration and 1586 μg/L (SD 1017) at 18 months of follow-up. 37 patients (5%) progressed to high-risk MDS or acute myeloblastic leukemia at a median of 155 days from registration. 62 patients (8%) have died within a median of 269 days from registration, 32 deaths were MDS related. The overall survival was 93% at 18 months of follow-up, with a progression-free survival of 90%. Differences in overall survival between transfusion-independent and transfusion-dependent patients were significant: 97% versus 85%, respectively (p<0.0001; Table 2). In the multivariate analysis transfusion-dependency, ferritin levels and IPSS score predicted survival (Table 2). The IPSS score had a significant prognostic impact on overall survival and progression-free survival in contrast to the WHO classification (Data not shown). Conclusions: Despite a high transfusion load the mean serum ferritin levels remained stable during treatment with iron chelation. Transfusion-dependent patients had a worse overall survival and progression-free survival with higher ferritin levels and higher IPSS score as compared to transfusion-independent patients. This report demonstrates the importance of detailed disease-management in low- and intermediate-1 risk MDS patients.
