Sickle Cell Disease Burden in North Lebanon

Background: Sickle cell disease (SCD) is one of the most prevalent hemoglobinopathies in Lebanon, where 0.1% of the population are affected by the disease, with the highest prevalence in North Lebanon. SCD burden has not been well characterized in this patient population. Moreover, there is limited understanding of the factors associated with complications of SCD. We hereby report on characteristics, complications, treatments and survival of a SCD cohort treated at a comprehensive SCD referral clinic in North Lebanon. Methods: Data were extracted from the health records and electronic registry of 335 SCD patients treated at the comprehensive SCD clinic of Nini hospital, Tripoli, North Lebanon between 2009 and 2019. The study population consisted of referred and newly diagnosed patients. Patients were considered to be newly diagnosed with SCD if there was a gap of ≤ 60 days between SCD diagnosis date and their first clinic visit date. Patients were regularly seen in the clinic at intervals ranging from every 2 months to 1 year depending on their age and disease severity. Patient characteristics, complications, treatment choices, and mortality were evaluated during follow-up. Follow-up was defined as the time between SCD diagnosis and last visit to the clinic. Complications included vaso-occlusive crisis (VOC), acute splenic sequestration (ASS), stroke, dactylitis, joint necrosis, priapism, leg ulcers, sepsis, iron overload and mortality. VOC events, defined as the composite of pain and/or acute chest syndrome (ACS), were only reported if they resulted in a hospitalization. Since history of VOC events was not well documented among referred patients, VOC events were assessed among patients newly diagnosed at the clinic. Results: The mean age of the study population at SCD diagnosis was 2.9 years (standard deviation [SD]: 4.3), with 73.1% of patients diagnosed within 3 years of age. Mean age at first visit to the clinic was 8.6 years (SD 10.0). 159 (47.5%) patients were female. The most common genotypes were Hemoglobin SS (233 [69.6%]), Hemoglobin Beta-0 Thalassemia (62 [18.5%]), and Hemoglobin Beta + thalassemia (27 [8.1%]). The mean number of follow up years between SCD diagnosis date and latest visit date to the clinic was 13.7 (SD: 10.5). 132 (39.4%) patients were newly diagnosed at the time of their first visit to the clinic. The most frequently encountered SCD clinical events were pain (189 [56.4%]) followed by ACS (135 [40.3%]), ASS (115 [34.3%]) and joint necrosis (55 [16.4%]). The incidence of stroke, pulmonary hypertension, priapism, leg ulcers and sepsis was low (3.3%, 4.2%, 6.0%, 3.0% and 3.9%). Persistent splenomegaly beyond 6 years was seen in 57 (17%) patients, 36 (63.2%) of these patients were of SS genotype. 276 (82.4%) patients required at least one hospitalization during their follow-up. Among newly diagnosed patients, 63% experienced at least one VOC event that led to a hospitalization with a mean of 0.4 (SD: 0.6) hospitalized VOC events per patient per year. 15 (4.5%) patients died during follow-up. The most common cause of death was stroke (3 [20%]). 84 (25.1%) and 76 (22.7%) patients underwent a cholecystectomy and surgical splenectomy respectively, and 30 (9.0%) patients underwent both. 236 (70.5%) patients were treated with Hydroxyurea. The mean age at introduction of Hydroxyurea was 11.5 years (SD: 10.1) and median starting dose was 15.2 mgs/kg/day. 281 (84%) patients received at least one blood transfusion during their follow-up. 37 (11.0%) patients received iron chelation during their follow up. 3 (0.9%) patients underwent bone marrow transplant and were cured of their disease. Conclusion: This first SCD study from North Lebanon demonstrates that SCD burden in North Lebanon is significant. Despite the high disease burden and the low community resources in this region, survival rate of this SCD patient population is relatively high. This can be attributed to the young age at diagnosis, the close comprehensive follow-up and the regular parent/patient education. The low rate of stroke, priapism and leg ulcers in this population warrants further investigation via disease associated markers and genetic determinants. As for priapism, it may be underreported due to social stigma in a conservative country as Lebanon. Noteworthy, Iron overload is under recognized and sub optimally treated. The association between specific risk factors and disease complications will be further addressed.

Introduction: The addition of gemtuzumab ozogamicin (GO) to 7+3 chemotherapy for newly diagnosed acute myeloid leukemia (AML) has been shown to significantly improve event-free survival (EFS) for cytogenetically favorable-risk AML, with marginal benefit for intermediate-risk AML, and no benefit for cytogenetically adverse-risk AML. Of note, with the exception of mutated FLT3-ITD, little is known about the impact of GO in ELN 2017-defined genotypically adverse-risk AML, and a recent randomized trial found no EFS benefit for 7+3+GO in patients (pts) with genotypically favorable-risk, NPM1-mutated AML. Since 2017, our institution incorporated GO into 7+3-based inductions for all "non-adverse" risk AML pts, as defined by wild-type FLT3 and no abnormalities on rapid FISH analysis for del(5q)/monosomy 5, del(7q)/monosomy 7, and del(20q). We report our experience treating all pts with "non-adverse" risk AML-as defined by this algorithm-with 7+3+GO. Methods: An institutional database was queried in order to identify all pts ≥18 years old who received 7+3-based chemotherapy for newly diagnosed AML between 2017 and 2020; pts who received the FDA-approved fractionated dose of GO were included in the analysis. Data collection included demographic variables, karyotype/FISH, targeted PCR analyses, and multigene NGS panels for AML-related mutations including, but not limited to, mutations in FLT3, NPM1, CEBPA, TP53, RUNX1, and ASXL1. Outcome data included response to induction, relapse, and death, as well as hematopoietic cell transplant (HCT) rates, conditioning regimens, and post-transplant complications. Results: Between January 2017 and July 2020, 96 pts received 7+3-based induction at our institution. Of these, 29 (30%) received 7+3 in combination with GO. Median age at diagnosis was 46 years (range 23-66), with 17 (59%) males. Sixteen (55%) pts had ELN favorable-risk AML (5 [31%] by cytogenetics and 11 [69%] by genotype), 6 (21%) pts had ELN intermediate-risk AML, and 7 (24%) pts had ELN adverse-risk AML (4 [57%] by cytogenetics and 3 [43%] by genotype). Median time from diagnosis to start of induction was 4 days (range 0-43). For cytogenetically adverse-risk pts, median time from diagnostic bone marrow biopsy to receipt of adverse karyotype results was 8 days (7-14). Median time from start of induction to receipt of multigene NGS results for all pts was 15 days (3-32). Overall, 22 (76%) pts achieved remission. All genotypically adverse-risk pts (1 with mutated TP53 and 2 with mutated RUNX1) were refractory to induction, while 3 of 4 (75%) cytogenetically adverse-risk pts (1 with t(6;9), 1 with monosomy 7, and 2 with 11q23 abnormalities) achieved remission. Eight of the 29 (28%) pts proceeded to HCT, including 4 adverse-risk pts. Of the adverse-risk pts, all received myeloablative conditioning prior to HCT and 3 (75%) developed veno-occlusive disease (VOD), with 2 (50%) requiring defibrotide therapy. In favorable/intermediate-risk pts, 4 (18%) proceeded to HCT (2 intermediate-risk pts in first remission and 2 favorable-risk pts in second remission). Of these, 2 (50%) received myeloablative conditioning and 1 (25%) developed VOD. At last follow-up, 23 of 29 pts (79%) remained alive, with a median overall survival not reached (range 1-29 months) and a median EFS of 20 months (9-31). The percentage of ELN favorable-, intermediate-, and adverse-risk pts who remained event-free at last follow-up was 75%, 33%, and 43%, respectively. Discussion: This single-center, retrospective cohort describes the outcomes of pts with "non-adverse" risk AML who received induction chemotherapy with 7+3+GO according to a pre-defined algorithm. Using this algorithm, 30% of all pts receiving 7+3-based inductions received GO. Of these, nearly 25% were ultimately found to have adverse-risk AML as defined by ELN 2017 criteria, largely driven by long turn-around times for karyotyping and NGS multigene panel results. No patient with genotypically adverse-risk AML by ELN criteria responded to induction chemotherapy, and 75% of cytogenetically adverse-risk pts who proceeded to HCT developed VOD. Routine use of 7+3+GO induction outside of the context of cytogenetically favorable-risk AML remains controversial, and further study is needed to define the role of GO, particularly for pts with ELN genotypically adverse-risk AML.

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 3096 Background. Several studies have demonstrated the impact of VTd on response rates and PFS either as induction or consolidation regimen. However there are limitations to these studies, especially that no data is available regarding the role of VTd consolidation in the context of bortezomib-triple based VTd induction regimen followed by a single auto. At completion of therapy, the response rate (ORR, PR and better) was 89%, VGPR+CR rate 74%, CR rate 29%, relapse rate and median PFS was 53% and 26 months (median F-up 32 months) in the VTd arm of the phase 3 IFM2007-02 trial conducted for newly diagnosed MM (Moreau et al, Blood 2012). In this study, only a minority of patients had received a consolidation or maintenance. On the other hand, Cavo et al. (Blood 2012) reported 97.5%, 92%, 61%, 39% 3-year progression and 62% estimated 5-year PFS (F-up 43 months) respectively in the VTd arm. VTd was given as induction before and consolidation after double auto in this upfront GIMEMA phase 3 trial (Cavo et al, Lancet 2010). We aimed to assess the efficacy and safety of VTd as consolidation therapy in the context of VTd as induction regimen followed by a single auto (VTd-auto-VTd regimen). Method. This study has included a first group of 121 newly diagnosed MM from 2009 to 2011 across 9 IFM centers. Patients were to be eligible for auto upfront, aged less than 65 and treated with VTd-auto-VTd regimen. The second cohort included MM treated with VTd-auto without consolidation from the IFM2007-02 trial (n=76). A third cohort comprised MM that received upfront a triplet Vd-based combination induction (VCd, VRd) -auto without consolidation (n = 40). Results. In the whole study, the median age was 56 years, the sex ratio was 1,49, 50% had ISS 2 and 3, 22% had adverse FISH [t(4;14); del17p] (similar in the 3 groups). Overall, the ORR was identical in the 3 cohorts at completion of therapy, 104 (86%), 72 (94%) and 32 (80%) for the cohort 1 to 3, respectively. Nevertheless, the CR rate was significantly greater in patients that received a consolidation (cohort 1), as compared to the cohorts 2 and 3 that did not receive any consolidation, 59 (53%) vs. 26 (34%) and 13 (32.5%), respectively (p=0.0001). Interestingly, the CR rates were identical at the end of the induction in the 3 cohorts, 13%, 15% and 22.5%, respectively. With a median follow-up of 25 months, the incidence rate of relapse was significantly greater in the cohort 2 and 3 versus 1, further demonstrating the importance of the consolidation, 25 (21%), 42 (55%) and 13 (32.5%) patients (p=0.0001), respectively; and 9 (8%), 6 (8%) and 8 (20%) had died in cohorts 1 to 3 (p=0.07). The median (95%CI) PFS was not reached in cohort 1, and was 32 (28;36) months and 30 (26;33) months in cohort 2 and 3, respectively. Importantly, 54.5%, 32% and 32% of patients were free of relapse at 32 months in the 3 cohorts, respectively. Similar data were obtained for TTP. The median (95%CI) OS was not significantly different in cohorts 1 to 3, although not reached for the first 2 cohorts and 38 (33;43) months for the 3rdcohort. The 3-year survival was 84%, 91% and 76%, respectively (p=ns). A longer follow up will certainly demonstrate greater survival end points benefit in favor for consolidation. The safety profile of the cohort that contained a consolidation was superimposable to that of the remaining 2 cohorts without consolidation. The incidence rate of hematological EIs of grade 3 and 4 was 4%, 6% and 8% in the 3 cohorts (p=ns), respectively. The incidence rate of neuropathy grade 1–2 and 3–4 was 5% and 2% in the cohort 1 with consolidation, but only 1% occurred during the consolidation. This data compares favorably to the 3% reported in the cohort 2 (Moreau et al. Blood 2012). We have also observed 9 (9%) thromboembolic events (TE), 8 of venous type and 1 arterial. None of them happened during the consolidation, and again, this incidence rate if superimposable to that reported in the IFM2007-02 vTd cohort. Conclusion. This study showed an impressive increase in CR rate in relation to the consolidation that translated into a lower relapse rate. This study also demonstrated that the VTd regimen, used both as induction and consolidation, in the context of a single auto upfront in MM, significantly contributed to improve clinical outcomes with an acceptable toxicity profile. VTd-auto-VTd compared very favorably to the other upfront protocols, and may become in the near future a standard of care in newly diagnosed patients with Myeloma.

Abstract Background High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) improves survival in multiple myeloma (MM). The introduction of novel agents challenged the role of ASCT at diagnosis. We conducted a multicenter 2X2 randomized trial comparing conventional chemotherapy plus lenalidomide with ASCT followed by maintenance with lenalidomide-prednisone (RP) or lenalidomide (R) alone in newly diagnosed young MM (NDMM) patients. Methods Eligible patients with NDMM ≤ 65 years were enrolled. All patients received Rd induction (four 28-day cycles of lenalidomide 25 mg day 1–21 and low-dose dexamethasone 40 mg day 1,8,15,22) followed by stem cell mobilization. Patients were randomized to receive consolidation with CRD [six 28-day cycles of cyclophosphamide (300 mg/m2 day 1,8,15), dexamethasone (40 mg days 1,8,15,22) and lenalidomide (25 mg days 1–21)] or MEL200-ASCT (melphalan 200 mg/m2 with stem-cell support). Patients were randomly assigned to receive subsequent maintenance with RP (28-day cycles of lenalidomide 25 mg days 1–21 plus prednisone 50 mg every other day) or R alone (28-day cycles of lenalidomide 25 mg days 1–21). Primary study endpoint was progression-free survival (PFS); secondary endpoints included safety, responses and overall survival (OS). Data cut off was May 30th, 2013. Results Three-hundred and eighty-nine patients were enrolled in the trial. Patient characteristics were well balanced between CRD (n=194) and MEL200-ASCT (n=195), and between R (n=195) and RP (n=194) arms. Median follow-up was 31 months. In the intent to treat (ITT) analysis, the median PFS was not reached with MEL200-ASCT and 28 months with CRD (the respective 3-year PFS was 60% vs. 38%, HR=0.62, 95%CI: 0.49-0.85, P=0.003). Median time from enrolment to maintenance was 14 months. In the population of patients eligible for maintenance, 2-year PFS from the start of maintenance was 73% for RP and 56% for R patients (HR= 0.57, 95%CI: 0.34-0.93; P=0.03). In the subgroup of patients who received MEL200-ASCT, 2-year PFS from the start of maintenance was 83% for patients who received RP and 64% for those who received R alone (HR=0.36 95%CI: 0.15-0.87, P=0.02). In the subgroup of patients who received CRD, 2-year PFS from the start of maintenance was 64% for patients who received RP and 47% for those who received R alone (HR=0.75, 95%CI: 0.40-1.39, P=0.36). At present, no differences in OS were noticed between patients randomised to received CRD or MEL200-ASCT, and between patients who received RP or R maintenance. As expected, the rates of grade 3-4 hematologic (85% vs. 26%, P<0.001) and non-hematologic (35% vs. 19%, P=0.003) adverse events (AEs) were higher in the MEL200-ASCT arm compared with the CRD arm. The main non-hematologic AEs were infections (18% vs. 5%, P=0.001) and gastrointestinal AEs (18% vs. 3%, P<0.001). Rates of grade 3-4 hematologic (8% vs. 7%, P=0.85) and non-hematologic (12% vs. 13%, P=0.88). AEs were similar in the RP and R arms. The main non-hematologic AEs in both RP and R groups were infections (3% vs. 3%). At present, 6 second primary malignancies and 3 cases of cutaneous basalioma have been reported. Conclusions MEL200-ASCT significantly prolonged PFS in comparison with CRD. At present no difference in OS was reported, this may be due to the low number of events and to the length of follow-up. The increase in toxicity with MEL200-ASCT did not adversely impact on efficacy. The addition of prednisone to lenalidomide maintenance significantly reduced the risk of progression in comparison with lenalidomide alone, without increasing the toxicity. Updated data with longer follow-up will be presented at the meeting.

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

Acute Myeloid

Background The therapeutic landscape for acute myeloid leukemia (AML) has become complex with recent drug approvals. CPX-351 has become standard-of-care for patients (pts) with therapy-related AML and AML with myelodysplasia-related changes. Moreover, earlier phase studies combining hypomethylating agents (HMA) and Venetoclax (HMA+Ven) in the frontline setting for elderly patients have demonstrated high response rates and improved survival. Given the overlapping indications, yet lack of comparative outcome data between these therapeutic regimens, treatment decisions have become challenging in the frontline setting. Therefore, we compared the outcomes of newly diagnosed AML pts receiving HMA+Ven vs. CPX-351. Methods We retrospectively annotated 119 pts that received frontline treatment with HMA+Ven and CPX-351 at Moffitt Cancer Center and Memorial Healthcare System between 2013 and 2019. Pts were divided in two cohorts: HMA+Ven (Cohort A) or CPX-351(Cohort B). Via comprehensive chart review of each patient that received HMA+Ven, we further classified a subgroup of pts meeting criteria to receive CPX-351 as CPX-351eligible. Clinical and molecular data were abstracted for each patient in accordance with IRB requirements. Overall response rate (ORR) was the combined total of complete remission (CR), complete remission with incomplete count recovery (CRi), and morphologic leukemia free state (MLFS). Fisher's Exact method was used to determine significance. Kaplan-Meier analysis was performed to estimate median overall survival (mOS) with log-rank test to determine significance. All p-values are two-sided. Results Out of 119 total pts, 41 pts received HMA+Ven (Cohort A) and 78 pts received CPX-351 (Cohort B) with baseline characteristics outlined in Table 1. Among 111 response evaluable pts, ORR was 64.1% in Cohort A, including 28.2% with CR and 28.2% with CRi (Table 2). ORR was 50.0% in Cohort B, comprised of CR in 29.2% and CRi in 18.1%. There was no difference in ORR between Cohort A and Cohort B (64.1% vs. 50%, p 0.17). A significantly greater fraction of pts in Cohort B underwent allogeneic stem cell transplant (allo-SCT) (24.4% vs. 2.4%, p=0.004). ORR was higher in pts with European LeukemiaNet (ELN)-defined favorable/intermediate (fav/int) risk compared to adverse risk group in Cohort A (100% vs. 58.3%, p=0.03), however there was no difference in Cohort B (52.6% vs. 49.1%, p=1.0). ORR was similar among adverse risk groups in both cohorts (58.3% in Cohort A vs. 49.1% in Cohort B, p=0.47). Among responders, median time to best response was significantly longer in Cohort A (61.0 days vs. 40.5 days, p<0.0001). Median duration of response was not reached (NR) in both cohorts. Impact of somatic mutations on ORR is represented in Figure 3. Median follow-up was 6.5 months (mo) in Cohort A and 13.0mo in Cohort B. Median OS was similar in both cohorts (A vs. B, 13.8mo vs. 11.1mo, p=0.82) (Figure 1). Among responders, mOS was NR in Cohort A and 18.2mo in Cohort B (p=0.88) (Figure 2). Compared to Cohort B, mOS was superior for pts with fav/int risk disease in Cohort A (14.2mo (B) vs. NR (A), p=0.045) and not different for adverse risk group (11.1mo (B) vs. 7.3mo (A), p=0.2). Prior HMA exposure was 26.8% in Cohort A and 29.5% in Cohort B for an antecedent hematologic malignancy, however it did not impact mOS (p=0.86) or ORR (p=0.7). Early mortality rates for Cohort A and B were similar at day 30 (2.4% vs. 0%) and day 60 (4.9% vs. 3.8%). Rate of relapse was similar between cohorts A and B (16.0% vs. 30.6%, p=0.24). We then compared the outcomes of pts in Cohort B to CPX-351eligible arm from Cohort A (n=14). ORR and mOS were similar in Cohort B and CPX-351 eligible arm (ORR: 50% vs. 50%, p=1.0; mOS 11.1mo vs. 13.8mo, p=0.43). Only 1 patient (7.1%) of the CPX-351eligible arm underwent allo-SCT. Conclusion Our study demonstrates that HMA+Ven results in comparable response rates and survival outcomes to patients receiving CPX-351 when used as an initial remission therapy for patients with newly diagnosed AML, however the median follow up for patients receiving HMA+Ven was short. Survival did not appear to be impacted by a significantly greater proportion of patients proceeding to allo-SCT in the CPX-351 arm. Overall, HMA+Ven may represent a reasonable frontline remission therapeutic choice in patients with AML and a randomized trial would seem justified.

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: Maintenance therapy post-autologous stem cell transplantation (ASCT) has shown to improve progression-free and overall survival in multiple myeloma (MM) and has largely become the standard of care. Consolidation therapy, a brief duration of more-intensive chemotherapy administered prior to maintenance, has been shown to further deepen responses and may improve long-term outcomes. Ixazomib, lenalidomide and dexamethasone (IRd) is an all oral regimen that has been shown to be active in newly diagnosed MM as well as relapsed disease. In this study, we are analyzing the safety and efficacy of IRd as consolidation therapy after ASCT (NCT02253316). Methods: Eligible patients, age 18-70 with newly diagnosed MM undergoing ASCT during first-line treatment, are being consented prior to ASCT. Approximately 4 months following ASCT, patients receive 4 cycles of consolidation therapy with IRd [ixazomib 4 mg on days 1, 8 and 15 of a 28-day cycle, lenalidomide 15 mg on days 1 through 21, and dexamethasone 40 mg on days 1, 8 and 15]. The primary end point is minimal residual disease (MRD) status. MRD is being assessed by ClonoSEQ where possible and by multi-color flow where not. Toxicity, IMWG response rate, PFS, and OS are secondary end points. One month after the last consolidation cycle, patients are randomized (1:1) to maintenance therapy with single-agent ixazomib (4 mg on days 1, 8 and 15) or lenalidomide (15 mg daily). In total, 240 patients will be enrolled on the trial. This presentation coincides with planned interim analysis 2 which included data from the consolidation phase only. Results: As of July 2018, 172 patients with NDMM have been enrolled from 10 centers within the US. The median age was 57 (range 28-70) and 67% were male. 76% were white, 10% African-American/Black, and 13% were another race. 39% were ISS Stage I, 30% were Stage II, and 20% were Stage III. All patients received proteasome inhibitors and/or IMIDs as front-line induction and melphalan as conditioning for ASCT. IRd consolidation started at a median of 110 days post-ASCT (range 80-138). IRd has been well tolerated. Only 4% (6/154) of patients have been unable to complete the 4 cycles of consolidation to date due to toxicity. Grade 3 hematologic toxicity has been uncommon; 4% neutropenia, 3% thrombocytopenia, and 2% anemia. There has been no grade 4 hematologic toxicity. Non-hematologic grade 3-4 toxicities have included: infection (8%), nausea/vomiting/diarrhea (3%), and transaminitis (1%). No grade 3-4 peripheral neuropathy has been reported. One case of grade 5 pneumonia was reported but was not considered related to study treatment. Following ASCT, the MRD-negative rate was 26% and this improved to 37% following consolidation. In the subset of patients with Clonoseq results available, the MRD negative rate improved from 19% to 27%. Clinical response rate improved similarly; prior to consolidation the VGPR or better rate was 76% including 39% CR/sCR. Following consolidation, the VGPR or better rate was 85% including 56% CR/sCR. 137 patients went on to receive maintenance with either ixazomib (n = 71) or lenalidomide (n = 66). At time of submission, the median follow-up from start of IRd is 14 months and 28 patients have relapsed/progressed and 6 have expired. An interim analysis is planned for 2019, representing the first comparison of ixazomib and lenalidomide maintenance. Conclusion: IRd consolidation following ASCT appears to be safe and effective. The all oral regimen is convenient for patients which greatly simplifies follow-up in the peri-transplant period. Study enrollment is scheduled to complete in Q1 of 2019.

Abstract Background: The combination of a proteasome inhibitor (PI), an immunomodulatory drug (IMiD), and dexamethasone is the current standard induction therapy for myeloma. Daratumumab, a monoclonal antibody directed against CD38, is highly effective in treating myeloma and improves response rates and progression free survival (PFS) when added to PI or IMiD. Ixazomib, lenalidomide and dexamethasone (IRd) is an effective, all oral, induction regimen that has been studied in phase 2 and 3 trials. We designed this trial to examine the feasibility and efficacy of adding daratumumab to the IRd regimen. Patients and Methods: Patients with previously untreated MM, with measurable disease and adequate organ function were enrolled irrespective of their transplant eligibility. The primary objective was to determine the rate of complete response to the IRD-Dara combination in patients with NDMM. Treatment consisted of Ixazomib 4mg days 1, 8, 15; lenalidomide 25 mg days 1-21, dexamethasone 40 mg, weekly and daratumumab 16 mg/kg, weekly for two cycles, every other week during cycles 3-6 and then every 4 weeks after that. Overall, 40 patients were accrued; data on 38 patients were available for analysis as of July 02, 2018 (Table 1). Results: The median age was 62 (41-81); 52.6% female. All patients were alive and progression free at last assessment with a median follow up of 5.2 (2.0-12.9) months (median 5 cycles, range 2-13). One patient had gone off for alternate therapy. Responses were rapid with 90% partial response or better (32% VGPR) after 2 cycles, and 100% PR or better (50% VGPR) for 32 patients who have completed 4 cycles. The overall best confirmed response rate among the 38 patients was 95% including 11% CR and 47% VGPR. Overall, 231 cycles have been administered across the study, with dose modifications/ hold required for ixazomib, lenalidomide, daratumumab and dexamethasone in 3 (8%), 11 (29%), 2 (5%), and 8 (21%) patients respectively, the most common reasons being hematologic and skin rash. A grade 3 or higher adverse event at least possibly attributed to the study drugs was seen in 42% of patients, hematologic in 37% and non-hematologic in 11% (Figure). 11 patients have so far proceeded to stem cell collection, all have collected adequate numbers of stem cells for one or two intended transplants(median CD34+ collected 8.4 million/kg; range 3.8-12.3). Updated results with additional 6 months of follow up and MRD testing will be presented at the meeting. Conclusion: This represents the first reported results of this combination for treatment of newly diagnosed myeloma. The early results from the use of IRd-Dara in newly diagnosed myeloma suggests excellent efficacy with rapid responses that deepen quickly over the initial cycles of therapy. The regimen was well tolerated with limited dose modifications and no discontinuation for toxicity and no influence on the ability to collect stem cells. Figure. Figure.

Acute Myeloid

Introduction: Acute myeloid leukemia (AML) is a heterogeneous disease with varied outcomes dependent on patient cytogenetic and mutational status. Thirty percent of adults with newly diagnosed AML have a mutation in the fms-related tyrosine kinase 3 (FLT3) gene. Midostaurin is a small molecule inhibitor that acts on multiple receptor tyrosine kinases, including FLT3. The RATIFY trial showed improved overall survival (OS) and event-free survival in patients treated with daunorubicin and cytarabine (7+3) plus midostaurin (Stone et al, NEJM 2017). In this trial, a dose of daunorubicin 60 mg/m2 was administered. High dose (HD) 90 mg/m2 daunorubicin significantly improved the rate of complete remission and overall survival, including in patients with FLT3-ITD (Luskin et al, Blood 2016). HD daunorubicin has also been shown to be more effective than idarubicin in patients with FLT3-ITD AML (Lee et al, J Clin Oncol 2017). This data raises the question of whether the combination of midostaurin and HD daunorubicin would further improve outcomes of FLT3 mutated AML patients, while maintaining a tolerable safety profile. The objective of this study is to describe the safety and efficacy endpoints of FLT3 mutated AML patients treated with HD daunorubicin plus midostaurin as part of induction therapy. Methods: We retrospectively reviewed clinical and molecular data of patients at Memorial Healthcare System, Moffitt Cancer Center, and Sylvester Cancer Center with newly diagnosed FLT3 mutated AML treated from May 1st, 2017 to July 1st, 2019. Clinical data was abstracted in accordance with institutional review board approved protocol. All patients were induced with HD daunorubicin 90 mg/m2 on days 1-3, cytarabine 100 mg/m2 on days 1-7, and midostaurin 50 mg PO twice daily on days 8-21. Growth factor and antimicrobial support were used per institutional guidelines. Demographics were analyzed using descriptive statistics. OS was analyzed using Kaplan Meier method. Other efficacy outcomes were CR, CRi (assessed according to the European Leukemia Network Criteria for AML), proportion of patients needing re-induction, and proportion of patients who underwent hematopoietic stem cell transplant (HSCT). Safety outcomes were adverse events (AEs) and early (30- and 60-day) mortality. Results: Twenty-six patients were included in the final analysis. Patient characteristics are outlined in TABLE 1. All patients were FLT3 mutated, as confirmed with molecular studies. The FLT3 subtype was ITD (high) in 3 patients, ITD (low) in 16 patients, TKD in 5 patients, and both in 2 patients. Seventy-seven percent of patients achieved a CR/CRi after one induction cycle, and 96.2% attained CR after two induction cycles. Median time to ANC and platelet recovery was 28 and 26 days, respectively. One patient died during the first 60 days, due to Enterococcus sepsis. The most common non-hematological AEs were nausea (77%), diarrhea (62%), mucositis (58%), rash (54%), and increased ALT (54%). Cumulative incidence of relapse in the cohort was 28% (n=7). Four patients relapsed pre-transplant and achieved CR2 with additional therapy. All 7 of these patients had co-occurring mutations of various types. Of the 20 patients who were considered transplant eligible, 13 (65%) underwent HSCT and 4 (20%) are pending transplant. Of the 13 transplanted patients, 3 experienced relapse post-transplant. After a median follow up of 14.5 months, median OS has not been reached. Conclusion: In our multi-center experience, induction with HD daunorubicin, cytarabine, and midostaurin is clinically effective and seems to be well tolerated. Short term mortality was low and AEs were manageable, with no unexpected safety signals. Also, CR/CRi rates were higher than previously reported, suggesting that the combination of HD daunorubicin and midostaurin may improve the outcomes of patients with FLT3 mutated AML. Future analyses with larger patient samples and longer follow up are warranted to further evaluate long-term safety and efficacy for this regimen.
