Abstract Background: Allogeneic Hematopoietic cell transplantation (HCT) is potentially curative therapy for MDS and AML. Although the median age at presentation is >65 years, most patients receiving HCT for these disorders are young (<60years). With the availability of Reduced Intensity Conditioning (RIC) many older patients are able to undergo HCT. The older age group is the most rapidly increasing cohort in CIBMTR registry. We analyzed the outcomes of AML and MDS patients' ≥ 60 years who received allogeneic sibling or unrelated donor HCT at our institution between 2009 and 2014. We also evaluated the influence of patient-, disease-, and transplant related factors on outcomes. Methods: Prospectively collected data available in the BMT databases at Mayo Clinic Florida, Arizona and Rochester as well as individual patient charts were reviewed after IRB approval. Patients with MDS or AML in complete remission at the time of transplant were included; those with active disease, induction failure, or prior transplant were excluded. HCT-specific comorbidity index (HCT-CI) and the disease risk index (DRI- Armand et al. Blood 2012) was noted. Survival estimates were calculated using the Kaplan Meier method. Associations with survival were explored using single variable Cox-regression modeling and log-rank tests. Results: 80 patients were included; 68 AML and 12 MDS. 31 (39%) were male. Median age 66 years (range 60-75). 33%, 52%, and 13% patients had ECOG status of 0, 1, >2, respectively. Thirty-seven patients (46%) had low or intermediate DRI and 43(54%) had high DRI. Twenty-two (28%), 24 (30%), and 34 (43%) patients had HCT-CI of 0, 1, or >2. There were equal number of sibling and unrelated donors; 85% were full HLA match and 15% with 1 or 2 mismatches; mean age of the donors was 52years (range18-74). Transplant conditioning was fludarabine-containing reduced intensity regimens in 78 (97%), 2 patients received myeloablative conditioning. The source of stem cells was peripheral blood in all patients. A median of 5.87 x10^6 CD34/kg donor cells were infused (range 1.58-10.92 X10^6). All patients received calcineurin inhibitor based GVHD prophylaxis (tacrolimus 56%, cyclosporine 44%); 6 patients also received ATG. The median follow up of survivors was 13 months. Kaplan Meier estimate of overall survival at 100 days, 1 year, and 2 years was 90%, 64%, and 55%. Cumulative incidence of relapse at 6 months, 1 year, and 2 years was 19.5%, 22.3%, and 27.1%. Relapse free survival at 2 years was 50%. The non-relapse/ treatment related mortality at 6 months, 1 year and 2 years was 11.7%, 15.9% and 15.9%. The rate of acute grade 2-4 GVHD was 30% and chronic GVHD was 39%. Univariate analysis identified secondary disease (compared to de novo) and high DRI(compared to low/intermediate) to be associated with worse mortality - HR 2.54 (1.31-4.93; P = 0.006), and 2.31 (1.13-4.73; P = 0.021), respectively. Probability of overall survival at 6 months, 1 year, and 2 years for patients with de novo disease (n=57) vs. secondary disease (n=23) was 87.1% vs. 64.5%, 71.1 vs. 45.6%, and 63.2 vs. 32.6%, respectively; P= 0.006. There was no effect of donor age, donor type or degree of mis-match on the survival. Conclusion: Allogeneic HCT is feasible in older patients with MDS and AML utilizing reduced intensity conditioning regimens with acceptable outcomes that are comparable to published results in younger patients. Patients with high DRI and secondary disease have poorer overall survival as compared to those with de novo disease and low/intermediate disease risk index. These data support other studies that age alone does not negatively influence transplant outcomes. Disclosures No relevant conflicts of interest to declare.

Purpose Myelodysplastic syndromes (MDS) are clonal hematopoietic disorders that are more common in patients aged ≥ 60 years and are incurable with conventional therapies. Reduced-intensity conditioning (RIC) allogeneic hematopoietic stem-cell transplantation is potentially curative but has additional mortality risk. We evaluated RIC transplantation versus nontransplantation therapies in older patients with MDS stratified by International Prognostic Scoring System (IPSS) risk. Patients and Methods A Markov decision model with quality-of-life utility estimates for different MDS and transplantation states was assessed. Outcomes were life expectancy (LE) and quality-adjusted life expectancy (QALE). A total of 514 patients with de novo MDS aged 60 to 70 years were evaluated. Chronic myelomonocytic leukemia, isolated 5q– syndrome, unclassifiable, and therapy-related MDS were excluded. Transplantation using T-cell depletion or HLA-mismatched or umbilical cord donors was also excluded. RIC transplantation (n = 132) stratified by IPSS risk was compared with best supportive care for patients with nonanemic low/intermediate-1 IPSS (n = 123), hematopoietic growth factors for patients with anemic low/intermediate-1 IPSS (n = 94), and hypomethylating agents for patients with intermediate-2/high IPSS (n = 165). Results For patients with low/intermediate-1 IPSS MDS, RIC transplantation LE was 38 months versus 77 months with nontransplantation approaches. QALE and sensitivity analysis did not favor RIC transplantation across plausible utility estimates. For intermediate-2/high IPSS MDS, RIC transplantation LE was 36 months versus 28 months for nontransplantation therapies. QALE and sensitivity analysis favored RIC transplantation across plausible utility estimates. Conclusion For patients with de novo MDS aged 60 to 70 years, favored treatments vary with IPSS risk. For low/intermediate-1 IPSS, nontransplantation approaches are preferred. For intermediate-2/high IPSS, RIC transplantation offers overall and quality-adjusted survival benefit.

Abstract Background Mobilized peripheral blood (PB) is the most common graft source for allogeneic hematopoietic transplantation (HCT) following reduced intensity conditioning (RIC). The impact, if any, of donor PB graft composition on major transplant outcomes in the RIC allogeneic HCT setting remains incompletely understood. Existing studies have focused primarily on CD34+ cell dose and report conflicting results, especially in relation to survival. The impact of total nucleated cell (TNC) dose has been less frequently evaluated, but limited studies with relatively small cohort sizes have reported higher TNC dose to be associated with improved survival. Methods In order to further explore the relationship between PB donor CD34+ cell dose, TNC dose and RIC HCT outcomes, we assessed 705 adult patients with hematological malignancies who underwent RIC allogeneic HCT at Dana Farber Cancer Institute/ Brigham and Women's Hospital (DFCI/BWH) between 2000 and 2010. The vast majority received a RIC regimen of fludarabine and busulfan (n=698). GVHD prophylaxis was tacrolimus based with or without sirolimus (524 vs. 171, respectively). Recipients of in vivo T-cell depletion (TCD) with antithymocyte globulin or ex-vivo TCD were excluded. The median age was 57 years (range,18-74). Patient's disease risk index (DRI) was categorized as low (n=164), intermediate (n=350), high (n=170) or very high (n=21) per Armand, et al (Blood, 2012). Transplants were categorized as matched (MRD n=273, MUD n=374) or mismatched (MMRD n=4, MMUD n=58). Results There was weak correlation between CD34+ cell dose and TNC (Spearman coefficient 0.25 [0.18-0.32]), and between CD34+/kg and TNC/kg with coefficient 0.25 [0.26, 0.39]. Cell doses for TNC effects were evaluated by quartiles. On multivariable analysis including age, DRI, donor source, gender, and CMV serostatus, higher TNC dose (top quartile, ≥10.8 x 10^10 cells) was independently associated with increased chronic GVHD (HR 1.33 [1.06-1.67], p=0.015) as well as decreased relapse (HR 0.74 [0.58-0.94], p=0.015). There was no effect on acute GVHD, engraftment, or non-relapse mortality. Importantly, higher TNC dose was associated with improved overall survival (HR 0.74 [0.59-0.94], p=0.014, Figure 1) and progression free survival, PFS (HR 0.76 [0.61-0.94], p=0.014). In contrast, although higher doses of CD34+ cells (> 10 x 10^6/kg vs. < 5 x10^6/kg) resulted in faster engraftment for both platelets and neutrophils (data not shown) and a decrease in non-relapse mortality ( HR 0.53 [0.30-0.93], p=0.027), there was no significant effect on acute or chronic GVHD incidence, relapse, PFS or survival. Conclusions These data suggest TNC dose is an important prognostic variable in T-replete RIC HCT with significant impact on survival and should, like CD34+ cell dose, be taken into consideration when planning donor graft infusions. Further studies are needed to confirm these data, and characterize the components of the PB graft that influence survival. Disclosures: No relevant conflicts of interest to declare.

Abstract Allogeneic stem cell transplantation offers curative therapy for many patients (pts) with high-risk hematologic malignancies. Donor availability remains a major limitation for many pts. The introduction of high-dose post-transplant cyclophosphamide (PTCy) has significantly improved the outcomes of pts undergoing haploidentical (HAPLO) stem cell transplants. The choice between a HAPLO or a one-antigen HLA mismatched unrelated donor (9/10 MUD) for pts lacking an HLA-matched donor remains unclear. Methods: We conducted a prospective non-randomized phase 2 clinical trial with two parallel arms, HAPLO (n=60) and 9/10 MUD (n=46) transplants, for pts with advanced hematologic malignancies or aplastic anemia who lacked an HLA-matched unrelated donor type at 10 loci (HLA-A, -B, -C, -DRB1, and -DQB1) using a MEL-based reduced-intensity conditioning regimen. The regimen included a single intravenous dose of MEL 140 mg/m2 (day -7), thiotepa 5 mg/kg (day -6), and four daily IV doses of fludarabine 40 mg/m2 (day -5 to day -2) (FM140). Thiotepa was intermittently available and was replaced by total body irradiation at a dose of 2 Gy on day -1. Pts >55 years (yr) old or with significant comorbidities received a lower MEL dose (100 mg/m2) (FM100). All pts with CD20-positive lymphoma received rituximab (375 mg/m2) on days -13, -6, +1 and +8. GVHD prophylaxis consisted of PTCy 50 mg/kg on day +3 and +4, and tacrolimus and mycophenolate for 6 and 3 months (mo), respectively. The stem cell source was unmodified bone marrow for both arms. Results: Patient characteristics are shown in Table 1. The median follow-up duration was 24 mo in the HAPLO arm and 29 mo in the 9/10 MUD arm. The cumulative incidence (CI) of neutrophil (ANC) recovery at day 45 was 95% and 98% in the HAPLO and 9/10 MUD arm, respectively. The median time to ANC recovery was 18 days in both arms; the median time to platelet recovery was 25 days in the HAPLO arm and 28 days in the 9/10 MUD arm. Primary graft failure developed in two pts in the HAPLO arm (one due to anti-donor HLA antibodies) and one patient in the 9/10 MUD arm. One pt in both arms developed mixed donor chimerism at day 100; otherwise, all pts in both arms achieved full (>95%) donor chimerism. Bone marrow was the graft source in all pts except 2 in the HAPLO arm and 8 in the 9/10 MUD arm who received a peripheral blood graft. The 1-yr overall and progression free survival were 70% and 60%, respectively, in the HAPLO arm (Fig. 1A) and 60% and 47%, respectively, in the 9/10 MUD arm (Fig. 1B). Day 100 CI of grade II-IV aGVHD and III-IV aGVHD were 28% and 3%, respectively, in the HAPLO arm versus 33% and 13%, respectively, in the 9/10 MUD arm; the 2-yr CI of chronic extensive GVHD was 13% and 14% in the two groups, respectively. The 1-yr CI of non-relapse mortality was 21% in the HAPLO arm and 31% in the 9/10 MUD arm, while the 1-yr relapse rate was 19% and 25% in the two groups, respectively. Conclusions: This study establishes PTCy, tacrolimus, and mycophenolate as an effective regimen for GVHD prevention in mismatched transplantation using both haploidentical and mismatched unrelated donor sources. Melphalan-based reduced-intensity conditioning is an effective regimen for a broad range of hematologic malignancies. Prospective randomized studies comparing haploidentical and unrelated donor sources are needed. Table 1.

With the advent of reduced intensity conditioning regimens, new treatment options are available to patients who suffer relapse of Hodgkin’s lymphoma (HL) following autoSCT, but the efficacy of this procedure is not proven. We retrospectively compared the cohort of adult patients who received alloSCT for relapse of HL following autoSCT to those who did not at a single institution. 64 patients underwent autoSCT for HL between 7/87 and 5/02: 41 for relapsed disease, 16 for primary refractory disease and 7 unclassified. Thirty-five patients (55%) relapsed at a median 12.5 months (range 0.9 to 140) after autoSCT. Eleven patients underwent alloSCT a median of 182 (35 – 645) days after relapse; 7/11 received reduced intensity conditioning, 5/11 received SCT from an unrelated donor. Of 24 patients who had relapsed after autoSCT (and did not receive an alloSCT), 16 survived at least 6 months and were considered in this analysis. Acute graft-versus-host disease (GVHD) > grade 2 occurred in only one patient, 5 /9 evaluable patients developed chronic GVHD (2 extensive). Five recipients of alloSCT have died: 2 with relapsed disease, 2 with disseminated fungal infections and 1 with interstitial pneumonitis. 6 patients remain alive, 5 remain free of disease. Median event free survival is12.5 months for recipients of alloSCT with median follow up of 3.1 years. Median overall survival is 4.1 years (64 days – 12.5+ years) and estimated overall survival is 71% at 3 years. This compares favorably with a median overall survival of 1.4 years in patients who survived at least 6 months, but did not receive alloSCT after relapse. Improved survival in the alloSCT cohort demonstrates that potent graft-versus-lymphoma activity can be achieved against HL without significant GVHD.

Abstract Background: Reduced intensity conditioning regimen (RIC) extends allogeneic hematopoietic cell transplantation (HCT) to older patients and patients with comorbidities. Compared to myeloablative (MA) conditioning, RIC has higher rate of relapse but lower rate of non-relapse mortality (NRM), resulting in similar survival. BMT CTN is conducting a prospective study to compare these two approaches. To further improve survival for older patients, a MA regimen with low NRM is needed. Timed sequential therapy (TST), giving two courses of chemotherapy 1 week apart, has higher antileukemic effect in in-vitro and in-vivo in studies of patients with AML, including phase 3 studies. We hypothesized that MA dose of busulfan delivered per principles of TST enhances antileukemic effect without increasing toxicity. We therefore designed a study to test safety of two MA schedules of busulfan targeting busulfan exposure (AUC) of 16000 μmol.min and 20000 μmol.min. AUC of 20000 μmol.minis close to total average drug exposure achieved with IV busulfan fixed dose of 12.8mg/kg. Methods: Patients were randomized to receive total busulfan exposure of 16,000 μmol.min(16K) or 20,000 μmol.min( 20K). Patients received IV busulfan 80 mg/m2 per day on day -13 and -12 in outpatient clinic, fludarabine 40 mg/m2 day x 4 (day -6 to -3) and IV busulfanx 4 (day -6 to -3). Busulfan was dosed to achieve target AUC of 16K or 20K based on pharmacokinetic studies done on day -13 and day -6. GVHD prophylaxis was Tacrolimus (day -2 onwards) and mini dose methotrexate-5mg/m2 on day 1, 3, 6, and 11. Stem cells were infused on day 0. Primary endpoint of the study was to compare 100 day non-relapse mortality in two arms with stopping rules built in for safety. Patients with hematological malignancies were eligible for the study if they had adequate organ function and 8/8 matched related or unrelated donor. We enrolled patients on this study who were suitable for RIC. When the study began, upper age limit for eligibility was 70 years, but this was increased to 75 years during the course of the study as safety was established. Fisher’s exact test was used to compare toxicity and NRM rates between arms. Cox proportional hazards regression was used to estimate the effects of clinical variables on overall survival. Results: 97 patients were enrolled on the study until the DSMB stopped the randomization and permitted continued accrual onto the higher dose arm with busulfan AUC of 20,000 μmol.min. 49 were randomized to busulfan AUC of 16K and 48 to 20K. For all patients, median age was 60 (18-75) years. 3 (2%) patients were less than 40 years of age, 12 (12%) 40-49, 33 (34%) 50-59, 39 (40%) 60-69, and 10 (10%) 70-79 years. 53 patients had AML/MDS, 24 CML/MPD, 16 myeloma, and 4 lymphoid malignancies. Based on revised disease risk index, 3 had low risk, 53 intermediate risk, 35 high risk, and 6 very high risk disease. Donor was related for 43 and unrelated for 54. Comorbidity scores were 0 in 23, 1-2 in 24, and ≥ 3 in 50. With a median follow up of 9.2 months (range 1.8-24) in surviving patients, 100 day NRM was similar in two groups, 4% in 16K and 6% in 20K (p=0.68). Maximum toxicity per patient was not significantly different between arms (Table 1, p=0.37). The 1-year unadjusted survival rates (95% CI) in combined disease risk indexes low and intermediate vs high and very high were 67 (50-79)% and 38 (19-57)%, respectively for all 97 patients. Multivariable Cox regression analysis for overall survival showed increased risk of death for older age (HR 1.05; p=0.03), comorbidity 3 and higher (HR 1.89 p=0.08), and high or very high risk index (HR 2.04; p= 0.05). After also accounting for donor relation and cell type, Bu AUC of 20k showed improved overall survival and a 50% reduction in the risk of death (HR 0.50, P= 0.058). Table 1.

Abstract Lenalidomide is an immunomodulatory drug that is FDA approved for treatment of 5q- myelodysplastic syndrome (MDS) and myeloma. It has also been tested as a salvage therapy of refractory/relapsed AML with encouraging activity, especially in patients (pts) who relapsed post allogeneic transplant (alloSCT). In this setting, it has been postulated that lenalidomide may re-activate donor immune system and enhance a graft-versus-leukemia effect. This hypothesis is also supported by evidence of increase graft-versus-disease (GVHD) observed in pts treated with lenalidomide post-alloSCT. Therefore, in order to prospectively study the safety, feasibility, and early impact on risk of disease relapse we performed a phase 1 dose escalation study of lenalidomide administered orally daily following reduced intensity conditioning (RIC) alloSCT in pts with leukemia and lymphoma eligible for transplant. Methods: Pts were enrolled on a two-step process, with initial enrollment prior to transplant followed by a re-registration evaluation post-transplant at day +60 (+/- 7 days) to ensure eligibility. At this screening, pts were required to demonstrate engraftment with ANC >1000/uL, platelet count ³50,000/uL, and T-cell chimerism ³40% by day +30. Pts were required to have a creatinine clearance ³50 mL/min, AST ²3 x ULN, and ECOG PS of 0-2. Grades 1 or 2 acute GVHD (aGVHD) were allowed if controlled on ² 20 mg of prednisone daily; pts with a history of grades 3 or 4 aGVHD were excluded. Lenalidomide was given orally daily for 28 days/cycle. Dosing escalation was performed using a standard 3 x 3 design, with dose level (DL) 1 = 5 mg , DL 2 = 10 mg, and DL 3 = 15 mg. Results: From 6/2011 to 10/2012, 17 pts with AML (n=13), CLL (n=1), and DLBCL (n=3) were enrolled (Table 1) and underwent RIC alloSCT. The majority of patients had a Disease Risk Index (Armand et al. Blood, 2014) of high or very high. Of enrolled pts, only 3 received lenalidomide. Of the pts who did not proceed to treatment at re-registration, 4 were ineligible due to relapse, 3 were ineligible due to elevated creatinine, 3 were ineligible due to GVHD, 2 declined, and 2 were not treated due to study closure. All pts who received lenalidomide were treated at DL 1. The first pt treated (00-06) received cycle 1 without toxicity. On cycle 2 day 9 he developed a skin rash consistent with acute GVHD and discontinued therapy. The second pt treated (00-11) developed skin rash and diarrhea on cycle 1 day 3 and was diagnosed with steroid refractory aGVHD of the GI tract. He expired from complications of treatment. The third pt treated (00-12) developed a skin rash and diarrhea on cycle 1 day 6. Lenalidomide was discontinued. Based on these outcomes, the study was closed due to concerns regarding the risk of severe aGVHD caused by lenalidomide. However, patients 00-06 and 00-12 remain alive and in CR days 958 and 751 post transplant, respectively. In the entire cohort, the median PFS was 103 days (range = 15-992) with median OS 103 days (range = 30-1085). Conclusion: Early administration of low-dose lenalidomide following alloSCT is not feasible due to potential increased risk of severe aGVHD and likelihood of elevated creatinine at this time point. However, 2 of 3 pts who received lenalidomide and responded to treatment for aGVHD remain in CR from their high-risk AML. Thus, an amended approach with lower/fewer dose of lenalidomide/cycle or alternatively, use in transplants that do not utilize calcineurin phosphatase inhibitors (such as T-cell depletion based approaches) warrants additional consideration.

7017 Background: Older patients are at increased risk for complications and death following allogeneic hematopoietic cell transplantation (allo-HCT). Traditional transplant-specific prognostic indices such as hematopoietic cell transplant comorbidity index (HCT-CI) may not capture all underlying geriatric vulnerabilities, and in-depth evaluation by a geriatrician prior to transplant may not always be available. We hypothesize that routine pre-transplant assessments by interdisciplinary clinical providers may help uncover additional geriatric deficits. Methods: Using an institutional database of 457 adults age 60 years and older (range 60-78.7) who underwent first allo-HCT for hematological malignancies from 2010 to 2017, we retrospectively examined the prevalence and the prognostic impact of pre-transplant geriatric deficits identified by interdisciplinary clinical providers including geriatric domains of functional activity, cognition, medication, nutrition, mobility, and routine laboratory tests. Results: With a median follow-up of 37 months for survivors, the 3-year probability of overall survival (OS) was 50% (95% CI 45-55). The 2-year cumulative incidence of non-relapse mortality (NRM) was 25% (95% CI 22-28). Among pre-transplant geriatric variables, we found that impairment in instrumental activities of daily living (IADL) was associated with increased NRM and inferior PFS and OS. In multivariate analyses, mismatched donor, age-adjusted HCT-CI > 4 (aaHCTCI), and IADL impairment were associated with NRM, while high/very high disease risk index (DRI), IADL impairment, and positive CMV status were associated with OS. The combination of IADL impairment with either aaHCTCI or DRI readily stratifies NRM and OS, respectively. Conclusions: Our findings establish a simple assessment tool to risk stratify older patients prior to allo-HCT using IADL and aaHCTCI and DRI. These results may provide an entry point for prospective, interventional trials to reduce NRM and toxicities for older allo-HCT patients.

PURPOSE Allogeneic hematopoietic cell transplantation (HCT) is the only potentially curative therapy for myelodysplastic syndromes (MDS), although it is infrequently offered to older patients. The relative benefits of HCT over non-HCT therapy in older patients with higher-risk MDS have not been defined. METHODS We conducted a multicenter biologic assignment trial comparing reduced-intensity HCT to hypomethylating therapy or best supportive care in subjects 50-75 years of age with intermediate-2 or high-risk de novo MDS. The primary outcome was overall survival probability at 3 years. Between January 2014 and November 2018, we enrolled 384 subjects at 34 centers. Subjects were assigned to the Donor or No-Donor arms according to the availability of a matched donor within 90 days of study registration. RESULTS The median follow-up time for surviving subjects was 34.2 months (range: 2.3-38 months) in the Donor arm and 26.9 months (range: 2.4-37.2 months) in the No-Donor arm. In an intention-to-treat analysis, the adjusted overall survival rate at 3 years in the Donor arm was 47.9% (95% CI, 41.3 to 54.1) compared with 26.6% (95% CI, 18.4 to 35.6) in the No-Donor arm ( P = .0001) with an absolute difference of 21.3% (95% CI, 10.2 to 31.8). Leukemia-free survival at 3 years was greater in the Donor arm (35.8%; 95% CI, 29.8 to 41.8) compared with the No-Donor arm (20.6%; 95% CI, 13.3 to 29.1; P = .003). The survival benefit was seen across all subgroups examined. CONCLUSION We observed a significant survival advantage in older subjects with higher-risk MDS who have a matched donor identified and underwent reduced-intensity HCT, when compared with those without a donor. HCT should be included as an integral part of MDS management plans in fit older adults with higher-risk MDS.
