Abstract Introduction: Little is known about current care patterns for pts with MDS across the US with respect to the use of available therapeutic agents. Using a cohort of 5,162 MDS pts we previously identified from the GE Centricity EMR database (GE Healthcare IT, Princeton, NJ) (Ma X, et al. Blood. 2015;126:abstract 3319), we examined associations between pt characteristics and treatment patterns, including sequence of therapies for pts with MDS. Methods: Pts with data in the EMR from Jan 2006 to end of Feb 2014 were included in this analysis. Pts were grouped by treatment received (erythropoiesis-stimulating agents [ESA], lenalidomide [LEN], hypomethylating agents [HMA; azacitidine or decitabine], and iron chelation therapy [ICT]), either alone, in combination, or as part of a sequence with other therapies. Transfusions were not included in this analysis, as transfusion data were often unrecorded due to transfusions occurring in facilities outside the EMR system. Pt characteristics were evaluated for each treatment group. Results: Of 5,162 pts evaluated, 1,843 (35.7%) received only 1 therapy, 2,079 (40.3%) received ≥ 1 therapy, with only 236 (4.6%) receiving ≥ 2 therapies. Pts who received ≥ 1 treatment of interest are shown in the Figure. Baseline characteristics for treatment groups are shown in the Table. A total of 85 pts were recorded as having deletion 5q by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) coding; of these, 66 were recorded as receiving ≥ 1 treatment. Pts were in the EMR system for a median of 29 days (date of first entry to date of last entry), with 36%, 26%, and 15% of pts present in the system for > 6 months, 1 year, and 2 years, respectively. The most common initial therapy was ESA (n = 1,508; 72.5% of treated pts). Pts treated with ESA first had a median age of 78.0 years; 1,330 (88%) received ESA exclusively. ESA-only pts were the oldest among the treatment groups (median age 79.0 years), had the highest proportion with comorbidities at baseline (69%), and most commonly had isolated anemia. Only a small proportion of pts treated with ESA first subsequently received LEN (n = 79; 5.2%) or HMA (n = 68; 4.5%) as second therapy; median ages of these patients were 76.0 and 73.5 years, respectively. 682 pts (32.7% of treated pts) received a therapy approved specifically for MDS, i.e. HMA and/or LEN, during their treatment. Pts who received LEN as first treatment (n = 258; 12.4% of treated pts) had a median age of 74.0 years. These pts had a lower median hemoglobin (Hb), lower median absolute neutrophil count (ANC), and similar median platelet count vs pts receiving ESA as first treatment. Most pts who received LEN as their first therapy received it exclusively (244; 94.6% of treated pts); a small number (n = 14) were subsequently treated with HMAs. Pts who received LEN second (n = 99) or third (n = 13) in a sequence of therapies were similar in age (median 76.0 and 74.0 years, respectively) and had similar Hb levels, higher ANCs, and higher platelet counts at baseline than pts who received LEN as first therapy. Most pts (n = 79; 80%) who received LEN as second therapy previously received ESA. Of 252 pts (12.1% of treated pts) who received HMA as first therapy, 228 (90.4%) received HMA only; median age of patients who received HMAs as first therapy was 75.0 years, and median Hb level, median ANC, and median platelet count were lower than in pts who received ESA as first therapy. Another 100 pts and 28 pts received HMA as second and third therapies, respectively; median age was 73.0 years in each group. Pts receiving HMA third had higher median Hb level, ANC, and platelet count than pts who received HMA as first therapy. Only 61 pts (2.9% of treated pts) received ICT as first therapy. Conclusions: Pts diagnosed with MDS in the USA are likely to be undertreated. Consistent with findings from physician surveys (e.g. Sekeres M., et al. J Natl Cancer Inst. 2008;100:1542-51), ESAs are the most commonly used therapies despite the lack of a labeled indication for MDS. ESAs are usually the first therapy chosen by physicians and often the only therapy pts with MDS receive. Use of LEN and HMA, which have been approved for the treatment of MDS for ~10 years, appears low in this EMR.

Abstract Abstract 3279 Background: ITP is an autoimmune disorder characterized by increased platelet destruction and suboptimal platelet production. Romiplostim stimulates platelet production via the TPO-receptor, and is recommended for second- and third-line treatment of chronic ITP in adults. We report final data from a large prospective study of romiplostim in adults with ITP of varying duration and severity. Methods: Eligibility criteria were broad: patients ≥18 years of age, who had received prior ITP therapies (final protocol amendment: ≥1, previous amendments: ≥3), with low platelet counts (final amendment: ≤ 30 × 109/L, previous amendments: ≤ 10, ≤ 20 × 109/L) or experiencing uncontrolled bleeding. The only excluded comorbidities were: hematological malignancy, myeloproliferative neoplasms, MDS and bone marrow stem cell disorder. Romiplostim was initiated at 1 (final amendment) or 3 (previous amendments) μg/kg/week, with dose adjustments allowed to maintain platelet counts ≥50 × 109/L. Patients could continue on study until they had access to commercially available romiplostim. Rescue medications were allowed at any time; concurrent ITP therapies could be reduced when platelet counts were > 50 × 109/L. Primary endpoint was incidence of adverse events (AEs) and antibody formation. Secondary endpoint was platelet response, defined as either (1) doubling of baseline count and ≥ 50 × 109/L or (2) ≥20 × 109/L increase from baseline. Results: A total of 407 patients received romiplostim, 60% of whom were female. Median (Q1, Q3) time since ITP diagnosis was 4.25 (1.20, 11.40) years (maximum 57.1 years), with 51% of patients splenectomised and 39% receiving baseline concurrent ITP therapies. Seventy-one percent of patients completed the study, with requirement for alternative therapy and withdrawn consent the most common reasons for discontinuation (5% each). Median (Q1, Q3) on-study treatment duration was 44.29 (20.43, 65.86) weeks (maximum 201 weeks), with a total of 20,201 subject-weeks on study. Incidence and type of AEs were consistent with previous studies. The most common serious treatment-related AEs were cerebrovascular accident, headache, bone marrow reticulin fibrosis (with no evidence of positive trichrome staining for collagen and no evidence suggesting primary idiopathic myelofibrosis), nausea, deep vein thrombosis, hemorrhage and pulmonary embolism, with each reported in 2 of 407 (0.5%) patients. All other serious treatment-related AEs were each reported in one patient. Eighteen patients died; 3 deaths (hemolysis, intestinal ischaema, aplastic anemia) were considered treatment-related. No neutralizing antibodies to romiplostim or TPO were reported. Approximately 90% of patients achieved each of the platelet response definitions, regardless of splenectomy status. Overall, median (Q1, Q3) time to response was 2 (1, 4) weeks for response definition 1, and 1 (1, 3) week for response definition 2. Median (Q1, Q3) baseline platelet count was 14 (8, 21) × 109/L. After 1 week of treatment median (Q1, Q3) platelet count had increased to 42 (18, 101) × 109/L. From week 8 onwards, and excluding counts within 8 weeks of rescue medication use, median platelet counts were consistently above 100 × 109/L (range 101.0–269.5 × 109/L). Median (Q1, Q3) average weekly romiplostim dose was 3.62 (1.99, 6.08) μg/kg. Summary/conclusions: This is the largest prospective study in adult ITP reported to date. The data reported here are similar to those reported for previous romiplostim studies, with romiplostim able to safely induce a rapid platelet response in adult ITP patients with low platelet counts or bleeding symptoms. Romiplostim is an important, well-tolerated, treatment option for adult ITP patients, which significantly increases and maintains platelet counts.

Abstract Background: Prophylactic replacement of coagulation factor VIII (FVIII) is the standard of care for patients with hemophilia A; however, prophylactic treatment with conventional FVIII products usually requires frequent intravenous infusions (3-4 times/week). Recombinant FVIII Fc fusion protein (rFVIIIFc), which is produced in a human cell line, binds the neonatal Fc receptor and utilizes the natural IgG recycling pathway to prolong the half-life of FVIII. The safety, efficacy and prolonged half-life of rFVIIIFc in adults and adolescents with severe hemophilia A were demonstrated in the phase 3 A-LONG study (NCT01027377, completed) and ASPIRE extension study (NCT01454739, ongoing). Here, we report cumulative long-term data on the safety and efficacy of rFVIIIFc in participants in these studies. Methods: This longitudinal analysis includes cumulative data from A-LONG and ASPIRE (as of the interim data cut, 6 January 2014) for subjects treated with ≥1 dose of rFVIIIFc (n=164). A-LONG evaluated 2 prophylaxis regimens-individualized (IP): 25 IU/kg on day 1 and 50 IU/kg on day 4 to start, then 25-65 IU/kg every 3-5 days, to target a 1-3 IU/dL FVIII trough level, and weekly (WP): 65 IU/kg dosed once weekly-as well as episodic (on-demand) treatment. Subjects completing A-LONG and meeting enrollment criteria for ASPIRE could participate in the IP, WP, or episodic treatment groups, or, if optimal dosing could not be achieved with IP or WP, in an additional modified prophylaxis (MP) treatment group. Subjects could change treatment groups at any point during ASPIRE. For efficacy analyses, data were summarized according to the treatment group in which each subject participated, for the time period they were in that treatment group; thus, subjects may be included in the analysis of more than one treatment group. Outcomes evaluated included: incidence of inhibitors (neutralizing antibody value ≥0.6 BU/mL as measured by the Nijmegen-modified Bethesda assay at a central laboratory, confirmed upon retesting within 2 to 4 weeks), adverse events (AEs), annualized bleeding rate (ABR), treatment of acute bleeds, and prophylactic dose and dosing interval. Results: Of the 164 subjects dosed with rFVIIIFc during A-LONG, 153 completed the study and 150 enrolled in ASPIRE. At the time of the interim data cut, 140 subjects were ongoing in ASPIRE. Cumulatively, subjects had a median (IQR) of 25.5 (24.6, 26.7) months of rFVIIIFc treatment, and a median (IQR) of 183.0 (120.5, 232.5) rFVIIIFc exposure days (EDs). No inhibitors were reported. The estimated inhibitor incidence rate (95% CI) was 0.0% (0.0, 2.2) overall (N=164), and 0.0% (0.0, 2.7) in subjects with ≥100 rFVIIIFc EDs (n=136). The type and incidence of AEs observed were consistent with those expected for the general hemophilia population. 84.8% of subjects reported ≥1 AE on study, with the majority assessed by the investigator as mild and unrelated to rFVIIIFc treatment. 17.7% of subjects experienced at least 1 SAE; none were assessed by the investigator as related to rFVIIIFc. There were no reports of anaphylaxis or serious hypersensitivity events, and no serious vascular thrombotic events. Median ABRs for subjects on IP and WP (MP was not an option during A-LONG) were generally lower with rFVIIIFc treatment compared with prestudy FVIII (Figure). In the IP treatment group, the year 1 and year 2 median spontaneous ABRs were 0.0. Overall, 89.1% of bleeding episodes were controlled with 1 infusion; 97.3% with 1 or 2 infusions. Among subjects treated with FVIII prophylaxis prior to entering A-LONG (n=79), 86% were dosed at least 3 times/week. With rFVIIIFc, 96% of these subjects extended their dosing interval compared with their prestudy product, while the median (IQR) total weekly prophylactic dose was comparable (prestudy FVIII: 78.0 [60.0, 102.0] IU/kg; on-study rFVIIIFc: 75.0 [70.0, 113.2] IU/kg). Conclusions: Longitudinal data from patients with severe hemophilia A treated with rFVIIIFc in A-LONG and ASPIRE demonstrate long-term safety, with no inhibitors observed in any subjects, and efficacy in the prevention and treatment of bleeding. Low median ABRs were maintained with extended prophylactic dosing intervals, without an increase in median prophylactic factor consumption. Figure 1. Figure 1.

Abstract Introduction: Thrombocytopenia (TCP) is a serious and life-threatening complication of advanced myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML). Eltrombopag (EPAG), an oral thrombopoietin-receptor agonist, is approved for treatment of chronic immune thrombocytopenic purpura and severe aplastic anemia. Preclinical studies showed that EPAG has potential antileukemic effects. A phase 1 study in advanced MDS/AML demonstrated an acceptable safety profile at doses up to 300 mg, with no worsening of leukemia, and it also showed a trend towards efficacy. Eltrombopag as monotherapy in MDS/AML has not been studied in a randomized fashion. Methods: In Study TRC114968 (ASPIRE), after 8 weeks of open-label, dose-defining EPAG treatment (Study Part 1), patients with highly advanced MDS or AML were randomized 2:1 to EPAG 100-300 mg or placebo (PBO) once daily for 12 weeks (Part 2), then entered a 6-month, open-label extension (Part 3). Patients were stratified by baseline platelet count (<10 Gi/L vs ≥10 Gi/L), and by MDS vs AML. Eligibility included 10-50% baseline bone marrow blasts and a baseline platelet count of <25 Gi/L. The primary endpoint was improvement in the clinically relevant thrombocytopenic event (CRTE) rate during the 12-week double-blind period. CRTE was a composite of a platelet transfusion requirement, significant bleeding event, or platelet count <10 Gi/L. Part 1 results have been presented previously. Blinded results for patients randomized in Part 2 of the study are presented below. Analyses of results by treatment arm, including those for the primary endpoint of CRTE, are ongoing and will be presented at the meeting. Results: A total of 145 patients were enrolled and randomized. According to WHO criteria, 72 (50%) had MDS and 73 (50%) had AML. See Table 1 for baseline characteristics. The majority of patients (n=91, 63%) were escalated to 300 mg (150 mg for East Asians) once daily. 70 patients (48%) completed the randomized portion of the study, and 58 (40%) entered the open-label extension. Patient disposition is described in Table 2. Out of the 144 treated patients, 97 patients (67%) have died (67 patients in Part 2 and 30 patients in Part 3). The main reasons for withdrawal from the study were adverse events (49 patients, 34%) and progressive disease (39 patients, 27%). The most common adverse events in Part 2 were petechiae, epistaxis, fatigue, pyrexia, and diarrhea. The main serious adverse events in Part 2 were pneumonia, sepsis, and febrile neutropenia. Liver test abnormality occurred in 1 (<1%). The median number of platelet transfusions for both groups was 10. Conclusions: This is the first study to evaluate EPAG as monotherapy in a randomized fashion in patients with advanced MDS or AML and severe thrombocytopenia. Overall safety was as expected for this patient population with no unexpected adverse events. This study provides evidence for the safety of EPAG in this mostly heavily pretreated patient population. An Independent Response Committee (IRC) is currently assessing responses and disease progression centrally by arm, and final data will be presented at the meeting.

Abstract Introduction: The median age at diagnosis for CLL pts in the US is 72 years. As clinical trials in CLL have largely enrolled younger pt populations, data on disease and pts' characteristics, patterns of care, prognosis, and molecular features in aged CLL pts are limited. With this in mind, we conducted a prospective study to update critical demographic data and patterns of care for aged CLL pt. Patients and Methods: Connect®-CLL is a US-based prospective, longitudinal, multi-center, observational registry that is aimed at understanding patterns of CLL management without a study-specific intervention. We enrolled pts treated at an academic (n=155) or community (n=1340) setting between 2010 and 2014. Eligible pts were adults with a clinical diagnosis of CLL who required therapy 2 or less months after enrollment. Data on demographics, baseline characteristics, and treatment selection are presented here using descriptive statistics. Continuous variables are reported using appropriate measures of dispersion and central tendency (means, medians, ranges and standard deviations) while categorical variables are summarized as number and percentage of the analysis population. Results: Of 1495 enrolled pts, 457 (30.5%) were ≥75 years (57.3% males, 94.2% white). Rai stage III/IV was noted in 33% and B symptoms (predominantly fatigue (58.4%)) were observed in 68.1%. These and other clinical baseline characteristics appeared similar to pts younger than 75 years except that older pts had more prior malignancies (33.5% vs. 19.8%) and co-morbidities (69.3% vs. 53.6%). Cardiac, neurologic, and renal disorders were the most common morbidities in pts ≥75 years (11.5%, 8.8%, and 4.6% respectively). Imaging studies were performed in 157 (60.2%) older pts and in 416 (65.7%) pts less than 75 years prior to initial therapy. Percentage of pts with bulky nodes (> 5 cm) by imaging was similar in the two groups, 19.3% overall. Prognostic biomarker data were available on 247 pts (178 (72%) <75 years; 69 (28%) ≥75 years). While a higher proportion of older pts had CD38+ CLL (55.1% vs. 40.5%, P=0.038), the proportions of patients with ZAP-70+ CLL were similar between the two groups. In total, 137 (9%) older and 378 (25%) younger pts had 17p and 11q analysis by FISH at enrollment prior to first-line therapy. Of these, 27.0% of pts ≥75 years and 20.6% of pts <75 years had a deletion of either 17p or 11q (P=0.125). Out of all pts enrolled in the registry, 894 (60%) received first-line treatment (261 (29%) pts ≥75 years and 633 (71%) <75 years) as their indication for study entry. Amongst these treated pts, interim analysis shows (data cutoff date: 25 June 2014) progressive marrow failure was more commonly used as the indication for therapy in older pts compared to younger pts (52.1% vs. 38.5%; P<0.001), while splenomegaly was a more common cause for therapy in younger pts (16% vs. 9%; P<0.01). Rai stage III/IV at time of first therapy was 46% and 49% for younger and older pts, respectively. Progressive lymphocytosis was used as the indication for therapy in one third of pts regardless of age. Seventy-four percent of older CLL pts received first-line therapies containing rituximab (R) vs. 85% in pts <75 years (P<0.0001). R-bendamustine was the most common first-line regimen for CLL pts ≥75 (23.4%) while FCR was more commonly given to pts <75 years (32.5%). R-monotherapy was used in 18.8% of older pts versus 9.5% in pts <75 years (P<0.0001). Of note, approximately 25% of CLL pts ≥75 years did not receive R-based regimens for initial therapy. Conclusions: Connect®-CLL is the largest prospective, multicenter CLL registry in the United States. CLL Pts ≥75 years more frequently overexpress CD38 and may more commonly demonstrate high risk cytogenetics by FISH, although the difference did not reach statistical significance. Pts ≥75 years also more commonly had co-morbid diseases, and surprisingly 25% did not receive first-line R-based therapy. CLL pts are rarely included in front-line clinical trials (<3%). Given that novel therapies are increasingly available for CLL patients a continued analysis is warranted to determine their use in elderly vs younger patients as well. A longer follow up is needed to evaluate the impact of these findings on outcomes. Disclosures Nabhan: Celgene: Honoraria, Research Funding. Off Label Use: Lenalidomide in CLL.

Abstract Background: Eltrombopag (EPAG), an oral thrombopoietin receptor agonist, is approved for treating thrombocytopenia in adults with chronic immune thrombocytopenia (ITP) with insufficient response to prior therapy. Pooled data from 2 similarly designed, randomized, double-blind, placebo (PBO)-controlled studies investigating safety and efficacy of EPAG in pediatric ITP are presented here. Methods: Subjects aged 1 to <18 years with a confirmed diagnosis of persistent or chronic ITP and a platelet count <30 Gi/L at day 1 were randomized 2:1 to EPAG or PBO and stratified by age: 12–17 years (Cohort 1), 6–11 years (Cohort 2), and 1–5 years (Cohort 3). Subjects could continue baseline ITP medications. After the PBO-controlled randomized phase, subjects were permitted to complete 17 or 24 weeks of treatment with open-label (OL) EPAG. Dose was adjusted based on platelet counts to a maximum of 75 mg daily. Results: A total of 174 subjects were enrolled in both studies; 171 received ≥1 dose of EPAG. 159 subjects were randomized (intent-to-treat population), and 157 received ≥1 dose of randomized study treatment (safety population). In the randomized period, 3 EPAG and 1 PBO subject discontinued study treatment, of which 2 EPAG and 1 PBO discontinued due to adverse events (AEs). In the OL-EPAG period, an additional 14 EPAG subjects discontinued study treatment, 6 due to AEs. Males comprised 47% of the EPAG and PBO groups and 20% and 24% were East Asians, respectively. Most subjects (93%) were diagnosed with ITP for ≥12 months, and 13% were receiving ITP medications at baseline. The majority of subjects (81%) received ≥2 prior ITP therapies. Most subjects (59%) had a baseline platelet count <15 Gi/L. All 9 (6%) splenectomized subjects were randomized to the EPAG group. Randomized Period A higher proportion of EPAG versus PBO subjects (62% vs 24%; P < 0.001) achieved a response with platelet counts ≥50 Gi/L at least once between weeks 1–6 (Cohort 1, 64% vs 11%; Cohort 2, 64% vs 27%; Cohort 3, 54% vs 36%, respectively). At each week, a higher proportion of EPAG subjects had a response versus PBO (Fig. 1). A lower proportion of EPAG subjects (13%) received rescue treatment compared with PBO subjects (31%; P = 0.009). The odds of having World Health Organization (WHO) bleeding grades 1–4 (0.19; P = 0.011) and clinically significant (WHO grades 2–4) bleeding (0.29; P = 0.007) were lower for EPAG versus PBO subjects. EPAG-Only Period Sustained reduction or discontinuation of baseline ITP medications, primarily corticosteroids, was achieved by 50% of subjects; 81% of subjects had a platelet count response at least once; 52% (n = 80/154) had a platelet count response for ≥50% of assessments; and 38% (n = 58/154) responded for ≥75% of assessments. For >13 of 24 weeks, 47% of subjects achieved responses (Fig. 2). The median average daily dose for EPAG-exposed patients in Cohorts 1, 2, and 3 were 64.0 mg (0.93 mg/kg), 57.6 mg (1.50 mg/kg), and 37.0 mg (2.02 mg/kg), respectively. AEs Similar proportions of subjects in the EPAG and PBO groups reported an AE during the randomization period. The most common AEs (≥10% of subjects) were headache, upper respiratory tract infection, and nasopharyngitis in the EPAG group, and headache, epistaxis, and vomiting in the PBO group. Serious AEs (SAEs) were reported in 8% of EPAG subjects versus 12% of PBO subjects. No SAEs were reported by >1 subject in either treatment group except epistaxis, which was reported by 2 subjects in the PBO group. No SAEs were common to both treatment groups. In the randomized period, an ALT elevation of ³3 x ULN occurred in 5 (4.7%) subjects in the EPAG group and no subjects in the PBO group. In the OL period, there were an additional 7 subjects with ALT ³3 x ULN. All elevations resolved either while still on treatment or after discontinuation of study treatment. Overall, the hepatobiliary laboratory findings were mostly mild, reversible, and not accompanied by impaired liver function. Fewer EPAG than PBO subjects reported bleeding AEs (17% vs 36%, respectively). No thromboembolic events were reported. Cataract events were experienced by 2 subjects who received EPAG; both had used corticosteroids and 1 had pre-existing cataracts. Conclusions: EPAG was safe and raised platelet counts in 62% of pediatric patients with persistent and chronic ITP during the randomized phase. Treatment with EPAG was well tolerated in both studies as evidenced by the low incidence of treatment discontinuations due to AEs.

Abstract Abstract 679 Chronic ITP is an autoimmune disease characterized by low platelet counts due to both increased platelet destruction and suboptimal platelet production. Immunosuppressive ITP therapies have variable response rates and may be associated with substantial side effects, limiting their use for long-term treatment. Romiplostim is a novel peptibody that increases platelet counts by a mechanism similar to thrombopoietin, and is approved for the treatment of chronic ITP. We present final results from a phase 3b, randomized, open-label study, comparing the incidence of splenectomy and treatment failure in adult nonsplenectomized ITP patients receiving either romiplostim or medical standard of care (SOC). Patients were randomized (2:1) to romiplostim or SOC. Eligible patients had a platelet count <50 × 109/L. Once-weekly subcutaneous romiplostim was administered with dose adjustments to target a platelet count between 50 and 200 × 109/L. SOC treatments were prescribed according to standard institutional practices or therapeutic guidelines; the only treatments not allowed were investigational agents (rituximab was allowed) or other thrombopoietic agents. Patients received romiplostim or SOC for 52 weeks, and those who did not subsequently transfer to another romiplostim study completed a 6-month off-treatment safety follow-up. Co-primary endpoints of the study were: the incidence of splenectomy and the incidence of treatment failure (defined as: platelet count ≤20 × 109/L for 4 consecutive weeks at the highest recommended dose and schedule, or major bleeding event, or change in therapy due to intolerable side-effect or bleeding symptoms). Patients who discontinued study during the treatment period were counted as having had splenectomy or treatment failure. To assess the impact of treatment discontinuation on the primary endpoints, a sensitivity analysis was conducted to determine the actual incidence of splenectomy or treatment failure. A total of 234 patients were randomized (romiplostim, 157; SOC, 77); 83% of romiplostim and 66% of SOC patients completed the study. Patients had been diagnosed with ITP for a median of 2 years (range 0.01 to 44 years) and 73% had received ≥2 prior ITP therapies. Patient characteristics were similar between treatment groups. The efficacy of romiplostim was significantly greater than that of SOC in both primary endpoint analyses. The incidence of splenectomy was 9% (14/157) in the romiplostim group compared to 36% (28/77) in the SOC group (OR, 0.17; 0.08, 0.35; p<0.0001), and the incidence of treatment failure was 12% (18/157) in the romiplostim group compared to 30% (23/77) in the SOC group (OR, 0.31; 0.15, 0.61; p=0.0005). Sensitivity analyses confirmed the primary endpoint analyses: the actual incidence of splenectomy was significantly lower in the romiplostim group (2/157, 1%) than the SOC group (15/77, 20%) [p<0.0001], and the actual incidence of treatment failure was significantly lower in the romiplostim group (6/157, 4%) than the SOC group (10/77, 13%) [p=0.009]. The incidence of bleeding events with a worst grade score ≥3 appeared lower for patients in the romiplostim group (3%) than the SOC group (7%). Safety analyses included only patients who received ≥1 dose of romiplostim or 1 type of SOC. During the 52-week treatment period, adverse events occurred in 96% (147/154) of patients receiving romiplostim and 92% (69/75) of patients receiving SOC. Serious adverse events occurred in 23% (35/154) of romiplostim and 37% (28/75) of SOC patients; serious adverse events were considered treatment-related in 5% (7/154) of romiplostim and 8% (6/75) of SOC patients. During the 6-month safety follow-up period, 36% (11/31) of romiplostim and 43% (18/42) of SOC patients experienced an adverse event; treatment-related adverse events occurred in none of the romiplostim patients and 2 of the SOC patients. Overall, 6 patients died: 1 (1%) in the romiplostim group and 5 (7%) in the SOC group. None of the deaths were considered related to study treatment or the underlying ITP. No patients tested positive for neutralizing antibodies to romiplostim or TPO. One romiplostim-treated patient showed an increase in bone marrow reticulin that was still within the normal range (Grade 2). In summary, romiplostim significantly reduced incidences of splenectomy and treatment failure in nonsplenectomized ITP patients compared to SOC. The safety profile of romiplostim was similar to SOC.

Abstract Abstract 3421 Background: BCR-ABL kinase inhibitors DAS, nilotinib and IM have become the primary treatment modality for patients (pts) with CML-CP. Pre-treatment comorbid conditions have been proposed to help select a second-line BCR-ABL inhibitor for IM-resistant CML-CP. The DASISION trial is a large Phase 3 trial comparing DAS with IM as initial treatment in pts with newly diagnosed CML-CP and has demonstrated superior efficacy of DAS 100 mg once daily after a minimum follow-up of 12 months (Kantarjian, H, et al. N Engl J Med 2010;362:2260). This analysis assessed the impact of baseline comorbidities on safety and efficacy of these agents when used as initial therapy for CML-CP. Methods: 519 pts with newly diagnosed CML-CP were randomized to either DAS 100 mg once daily (n = 259) or IM 400 mg once daily (n = 260). Key exclusion criteria included serious uncontrolled medical disorders or active infections; uncontrolled or serious cardiovascular disease; prior or concurrent malignancy; inadequate hepatic or renal function; and ECOG performance status of ≥ 3. Pts were analyzed according to the number (0, ≥ 1 and ≥ 2) and type of baseline comorbidity (allergic, dermatologic, diabetes, endocrine-metabolic, gastrointestinal, hematologic-lymphatic, hepatobiliary, hyperlipidemia, musculoskeletal, renal and respiratory), and age (< 46, 46–65 and > 65 y). Complete cytogenetic response (CCyR), major molecular response (MMR) and drug-related adverse events (AEs) were analyzed across these groups. Cardiovascular comorbidities were analyzed separately and are not included here. Results: Across the 2 treatment arms, 74% of the pts had 31 baseline comorbidity and 47% had 32. The distribution of comorbidities including allergic (n = 61), dermatologic (n = 62), diabetes (n = 31), endocrine/metabolic (n = 98), gastrointestinal (n = 176), hematologic/lymphatic (n = 57), hepatobiliary (n = 56), hyperlipidemia (n = 41), musculoskeletal (n = 150), neoplasia (n = 17), renal (n = 33) and respiratory (n = 72) was balanced across the 2 arms. Proportions of pts across 3 Hasford risk groups were similar between pts with baseline comorbidity and those without. Safety profiles of DAS and IM in pts with and without baseline comorbidities were comparable (Table). Proportions of pts with at least 1 dose interruption or dose reduction were also similar with or without any comorbidity (Table). Pts with 32 comorbidities and pt grouped by comorbidity type including diabetes mellitus, hepatobiliary conditions and hyperlipidemia also had generally similar safety profiles. In both arms, the 12-mo rates of CCyR and MMR were similar (Table). In DAS-treated pts with diabetes (n = 18), hepatobiliary conditions (n = 32) and hyperlipidemia (n = 22), CCyR rates were 67, 78 and 96%, respectively; the respective MMR rates were 44, 56 and 59%. IM pts with diabetes (n = 13), hepatobiliary conditions (n = 24) and hyperlipidemia (n = 19) had CCyR rates of 69, 75 and 79%, respectively; and MMR rates of 15, 29 and 32%, respectively. In DAS-treated pts, CCyR rates were 88% for pts aged < 46 y (n = 128), 78% for those aged 46–65 y (n = 111) and 85% for those aged > 65 y (n = 20); the corresponding MMR rates were 45, 47 and 50%, respectively. The corresponding IM age groups (n = 111, 125 and 24, respectively) had CCyR rates of 70, 70 and 83%, respectively; and MMR rates of 26, 30, 29%, respectively. Safety profiles were generally similar across age groups in both treatment arms, except that fluid retention rates in pts aged < 46, 46–65 and > 65 y were 13, 25 and 35%, respectively, for DAS; and 34, 45 and 67%, respectively, for IM. Conclusions: The presence of baseline comorbidities appeared to have no effect on the safety and efficacy of either DAS or IM as initial therapy for CML-CP.

Ruxolitinib (Jakafi®) is the one approved therapy for myelofibrosis (MF) based on reduction of splenomegaly and symptoms but JAK inhibition has not proven to significantly modify disease progression. There remains the need for novel therapies with distinct modes of action that can improve the patient experience of MF and impact progression. Lysine-specific demethylase, LSD1, is an epigenetic enzyme critical for self-renewal of malignant myeloid cells and differentiation of myeloid progenitors. LSD1 bound to GFI1b permits maturation of progenitors to megakaryocytes and enables their normal function. IMG-7289 (bomedemstat) is an orally available LSD1 inhibitor. In mouse models of myeloproliferative neoplasms (MPN), IMG-7289 reduced elevated peripheral cell counts, spleen size, inflammatory cytokines, mutant allele frequencies, and marrow fibrosis (Jutzi et al. 2018) supporting its clinical development. IMG-7289-CTP-102 is an ongoing, multi-center, open-label study that recently transitioned from a Phase 1/2a dose-range finding study to a Phase 2b study of IMG-7289 administered orally once-daily in adult patients with intermediate-2 or high-risk MF resistant to or intolerant of ruxolitinib. The key objectives are safety, PD, changes in spleen volume (MRI/CT) and total symptoms scores (TSS) using the MPN-SAF instrument. Inclusion criteria included a platelet count ≥100K/μL. Bone marrow (BM) biopsies and imaging studies (both centrally-read) were conducted at baseline and during washout (post-Day 84). The MPN-SAF was self-administered weekly. Phase 1/2a patients were treated for 84 days followed by a washout of up to 28 days. Patients demonstrating clinical benefit could resume treatment for additional 12 week cycles. Dosing was individually tailored using platelet count as a biomarker of effective thrombopoiesis. Patients were started at a presumed sub-therapeutic dose of 0.25 mg/kg/d and up-titrated weekly until the platelet count rested between 50 and 100K/μL. This preliminary analysis includes 20 patients; 18 enrolled in the Phase 1/2a study, 2 in the Phase 2b portion. 50% had PMF, 35% Post-ET-MF, 15% Post-PV-MF. The median age was 65 (48-89) with 70% males. The median baseline platelet count was 197 k/μL (102-1309k/μL). 12 patients (56%) were transfusion-dependent at baseline. Sixty percent were IPSS-classified as high risk, the remainder, intermediate risk-2. 71% had more than 1 mutation of the 261 AML/MPN genes sequenced of which 63% were high molecular risk (ASXL1, U2AF1, SRSF2) mutations; 31% had abnormal karyotypes. Sixteen patients completed the first 12 weeks; 4 patients withdrew, one due to fatigue (Day 33), one for progressive disease (Day 39), one due to physician decision (Day 76), one for an unrelated SAE of cellulitis (Day 83). All patients were up-titrated from the starting dose 0.25 mg/kg to an average daily dose of 0.89 mg/kg ± 0.20 mg/kg, the dose needed to achieve the target platelet count range; 17 achieved the target platelet range in a mean time of 45 days. Of patients evaluable for response after cycle 1 in Phase1/2a (N=14), 50% had a reduction in spleen volume from baseline (median SVR: -14%; -2% to -30%). Further, 79% (N=11) recorded a reduction in TSS (mean change -28%; -13% to -69%); for 21% of patients (N=3), the change was &gt;-50%. Improved BM fibrosis scores at Day 84 were observed in 2/13 patients. Two patients had improvement in transfusion requirements. Plasma IL-8 levels were significantly elevated in 6/14 patients at baseline and dropped in a dose-dependent manner over 21 days in 5/6 patients. The mean duration of treatment is 166 days (14-539) at the census point in this ongoing study. Nineteen patients (95%) reported 358 AEs of which 22 were SAEs. Of the SAEs, 2 were deemed by investigators as possibly related: painful splenomegaly and heart failure. There have been no safety signals, DLTs, progression to AML, or deaths. This is the first clinical study of an LSD1 inhibitor in patients with MPNs. Once-daily IMG-7289 was well-tolerated in a heterogeneous population of patients with advanced MF and limited therapeutic options. Despite under-dosing and slow dose escalation, IMG-7289 improved symptom burdens in most patients and modestly reduced spleen volumes in a subset of patients. The Phase 2b 24-week expansion study with more aggressive dosing aimed at preserving safety and enhancing efficacy is open for enrollment in the US, UK and EU.

Background: MM clinical trials often have stringent eligibility criteria that limit the enrollment of patients (pts) reflective of the general patient population (Shah, Clin Lymphoma Myeloma Leuk 2017). The Connect® MM Registry, a prospective observational study of pts with newly diagnosed MM (NDMM) in the US, provided the opportunity to examine differences between pts with MM who were identified as RCT-eligible vs -ineligible, to observe the generalizability of clinical trial results to real-world clinical settings. Differences in baseline characteristics, treatment, clinical outcomes, and HRQoL were examined in RCT-eligible and -ineligible pts from this registry, which represents an unselected, broad real-world population. Methods: Pts with NDMM were enrolled at 250 community, academic, and government sites. Eligible pts were ≥18 y of age with symptomatic MM diagnosed ≤2 months preenrollment per the International Myeloma Working Group (IMWG) criteria. For this analysis, pts were considered ineligible for RCT per the following key exclusion criteria previously described: absolute neutrophil count ≤1.5 × 109/L, platelet count ≤75 × 109/L, creatinine >2.5 mg/dL, AST/ALT >3 times the ULN, peripheral neuropathy grade >2; ECOG PS 3/4; history of myelodysplastic syndromes/other hematologic malignancies, or solid tumors (Shah 2017). Sites administered pt HRQoL questionnaires and provided clinical data at baseline and quarterly during follow-up until death or study discontinuation. Differences in HRQoL at baseline, changes from baseline to 1 and 2 years, and survival outcomes, adjusted for covariates via propensity score, were compared between RCT-eligible/-ineligible pts. Results: Of the 3011 pts enrolled, 2873 pts met the CRAB (hyperCalcemia, Renal failure, Anemia, and Bone disease) criteria per IMWG at enrollment. Of these, 1622 (56.5%) were identified as RCT-eligible and 1251 (43.5%) as RCT-ineligible (data cut-off February 7, 2019). Both groups were similar in median age, sex, race, and ethnicity distribution, although the RCT-ineligible group had more pts aged ≥75 y (26.3% vs 23.2%) and more pts with ECOG PS 3/4 (6.2% vs none). Overall, 34.5% of RCT-ineligible pts received a transplant vs 42.8% of RCT-eligible pts. More RCT-ineligible pts had ISS stage III disease (39.4% vs 19.8%), elevated calcium (≥11.5 mg/dL; 12.7% vs 6.8%), elevated creatinine (>2.0 mg/dL; 40.3% vs 6.5%), and low hemoglobin (<10 g/dL or >2 g/dL <LLN; 60.8% vs 40.3%). Use of triplet treatment (54.2% vs 56.2%) and alkylator (24.9% vs 20.1%) was similar between the RCT-ineligible/-eligible groups. Lenalidomide + bortezomib + dexamethasone (RVd) was the most common initial therapy, and R was the most common maintenance therapy in both groups, but fewer RCT-ineligible pts received RVd as initial therapy (23.9% vs 31.0%) and R as first maintenance regimen (18.1% vs 22.7%). Absolute baseline HRQoL scores were significantly higher, indicating better HRQoL, in RCT-eligible (115.9) vs -ineligible (111.5) pts on the Functional Assessment of Cancer Therapy-Multiple Myeloma (FACT-MM) Total score (P=0.007), FACT-MM Trial Outcome Index (74.3 vs 70.3, P=0.002), and FACT-MM Subscale (37.3 vs 35.5, P=0.003). Scores were similar for EuroQol-5D Overall Index (0.73 vs 0.72, P=0.5) and Brief Pain Inventory (3.42 vs 3.43, P=0.9). Both RCT-eligible and -ineligible pts showed significant improvement in HRQoL from baseline at years 1 and 2, although the magnitude of improvement was similar between both groups (Fig. 1a and b). RCT-ineligible pts showed significantly shorter median PFS and OS vs RCT-eligible pts (Fig. 2 & 3, respectively). Conclusions: The CONNECT MM registry provided the opportunity to examine key differences between RCT-eligible and -ineligible pts. By applying common RCT eligibility criteria, a substantial proportion of MM pts (43.5%) in this real-world population may have been ineligible to participate in a RCT. RCT-ineligible pts had advanced disease, poor performance status, and poor laboratory parameters at baseline vs RCT-eligible pts, which could affect PFS and OS. These findings enhance our understanding of HRQoL among MM pts, which at present, is largely based on RCT participants. A similar magnitude of HRQoL improvement in both groups at 1 and 2 years suggests the need to evaluate RCT eligibility criteria in MM to help broaden enrollment and maximize external validity.

Abstract Background BCMA is a cell surface receptor in the TNF superfamily with expression restricted to B lineage cells at later stages of differentiation, which is required for the survival of long lived plasma cells. BCMA is also expressed on MM cells. GSK2857916 is a humanized IgG1 anti-BCMA antibody conjugated to the microtubule disrupting agent monomethyl auristatin-F via a stable, protease-resistant maleimidocaproyl linker. Upon binding to BCMA, GSK2857916 is rapidly internalized and active drug released in the cell. GSK2857916 also exhibits enhanced antibody-dependent cell-mediated cytotoxicity resulting from afucosylation of the Fc domain, and potentially induces immunogenic cell death. Here we report results from the Part 2 expansion of a Phase 1 study of GSK2857916 in heavily pretreated MM pts. Methods BMA117159 (NCT02064387) is a Phase I, first in human, open-label study investigating GSK2857916 in relapsed/refractory MM and other hematologic malignancies expressing BCMA. The primary objective is safety and determination of maximum tolerated dose and recommended Phase 2 dose (RP2D); secondary objectives include pharmacokinetics (PK), antidrug antibody (ADA) incidence, and overall response rate (ORR). Dose escalation (Part 1) and expansion (Part 2) in MM pts is complete, and enrollment into a lymphoma cohort is ongoing. GSK2857916 is dosed once every 3 weeks as a 1-hr intravenous infusion, without required prophylaxis for infusion-related reactions (IRR). Eligible MM pts must have been treated with alkylators, proteasome inhibitors (PI), immunomodulators (IMiDs), and stem cell transplantation (if eligible) and must have documented progression on or within 60 days of last therapy. Pts remain on treatment until progression, unacceptable toxicity, consent withdrawal, or completing 16 treatment cycles. All pts received steroid eye drops for 4 days with each infusion to mitigate corneal events. Results Part 1 results (N=38) were previously presented (Blood, 2016 128:1148); no maximum tolerated dose was identified and the RP2D was determined to be 3.4 mg/kg. Part 2 enrolled 35 MM pts treated at the RP2D: median age is 60 years (range 46-75) and 49% are male. Fifty-seven percent received ≥5 prior lines of therapy (range 1- &gt;10). All pts received and 97% were refractory to PI, all pts received and 91% were refractory to IMiDs, 40% received and 37% were refractory to daratumumab, and 89% were double-refractory to PI and IMiDs. Median number of infusions was 5 (range 1-13) and 54% of pts received ≥5 infusions. The ORR for Part 2 was 60% (21/35; 95% CI 42.1-76.1), including 1 sCR, 2 CR, 15 VGPR, and 3 PR. The ORR in pts previously treated with daratumumab was 43% (6/14; 95% CI 17.7-71.1). Median duration of response was not reached, with a median PFS of 7.9 months (95% CI 3.1- NA). All pts had at least 1 adverse event (AE); the most frequent (≥25%) regardless of cause were corneal events (63%), thrombocytopenia/platelet count decreased (57%), anemia (29%), AST increased (29%), and cough (26%). Corneal events (most frequent ≥20%: vision blurred, dry eye, photophobia) were mostly Grade (Gr) 1/2 and were reversible. Gr 3/4 AEs reported in ≥10% of pts were thrombocytopenia/platelet count decreased (34%) and anemia (14%). Serious AEs were reported in 40% (14/35) of pts. With no pre-medication, 8 pts had IRRs (2 Gr 1, 3 Gr 2, 3 Gr 3) that occurred with the first infusion, resolved, and did not recur with subsequent infusions. A total of 18 pts discontinued treatment for disease progression (n=15), AE (n=2; thrombocytopenia, CPK elevation), or pts decision (n=1); 17 pts are ongoing. Conclusion GSK2857916 monotherapy demonstrated encouraging single agent activity with an ORR of 60%, and deep (51% ≥VGPR) and durable responses in heavily pre-treated relapsed/refractory MM pts who have limited treatment options. The target and therapeutic mechanisms of action differentiate GSK2857916 from currently approved drugs in MM. Results show a manageable safety profile, with thrombocytopenia/platelet count decreased and low grade corneal events being the most frequently reported AEs and most frequent reason for dose modifications. Detailed safety and clinical activity together with results from correlative analyses will be presented.
