The Global aHUS Registry: Characteristics of 826 Patients with Atypical Hemolytic Uremic Syndrome

Abstract Background: Atypical hemolytic uremic syndrome (aHUS) is a rare, genetic, life-threatening disease predominantly caused by chronic, uncontrolled complement activation that leads to thrombotic microangiopathy and renal and other end-organ damage. The aHUS Registry, established in April 2012, is an observational, noninterventional, multicenter, global initiative to collect information on patient outcomes regardless of treatment approach. It facilitates availability of follow-up data for eculizumab. Methods: Patients with clinical diagnoses of aHUS (irrespective of identified complement abnormality or treatment) are eligible. Demographic, medical/disease history, and treatment outcomes data are collected at enrollment and prospectively thereafter. Results: By June 30, 2015, 826 patients enrolled (Table). Overall, 54.7% of patients, including 45.1% of pediatric and 62.7% of adult patients, were female. Patients were most commonly enrolled after their first TMA event. Thrombosis occurred more frequently in adult than pediatric patients. Nonrenal conditions, including gastrointestinal, cardiovascular, central nervous system, and pulmonary, were common in both age groups and occurred in 11.0%‒20.3% overall. Eculizumab was administered to 57.3% of patients, of whom 87.3% were treated prior to enrollment. Conclusions: Registry baseline characteristics demonstrate differences between pediatric and adult patients with aHUS, notably frequencies of thrombosis. Nonrenal conditions are frequent in both age groups. Ongoing and future analyses will further enhance understanding of aHUS history and progression. Additional clinical sites are encouraged to enroll patients to facilitate knowledge acquisition and optimization of patient care and quality of life.

Abstract Background: Eculizumab was demonstrated to effectively treat and prevent thrombotic microangiopathy (TMA) and to improve renal function and hematologic parameters for up to 2 years in4 previous prospective clinical trials and in 1 retrospective study of patients with atypical hemolytic uremic syndrome (aHUS). Patients in these studies enrolled in a long-term follow-up study, in which rates of TMA were evaluated during eculizumab treatment and during discontinuation from eculizumab. Methods: Data were gathered from an ongoing, observational, multicenter study of aHUS patients treated with eculizumab in 5 prior clinical studies. The primary endpoint was TMA event rate post-parent study during on-treatment (ON; among patients receiving eculizumab) and off-treatment (OFF; among patients who discontinued eculizumab) periods. Results: As of March 28, 2015, 87 patients, including 35 children <18 years of age (40%) and 52 adults ≥18 years of age (60%), enrolled in the study (Table). Of these, 76 patients had ON and 39 patients had OFF treatment periods with median follow-up of 26.1 and 20.1 months, respectively. A reduced dosage of eculizumab was received by 33 of 87 patients (38%). Seventeen of 39 patients (44%) reinitiated eculizumab after therapy discontinuation. The TMA event rates were 7.3 and 19.9 per 100 patient-years for ON and OFF patients, respectively. The rate of TMA in ON patients was greater in those receiving reduced dosing compared with label recommendations (Table). OFF patients had higher estimated glomerular filtration rates at time of discontinuation than ON patients. Age, frequencies of higher-risk complement factor mutations (CFH, C3, or CFB) and kidney transplant status were not different between ON and OFF patients. Factors that independently predicted TMA events included: ON treatment status (compared with OFF; hazard ratio [HR], 0.19; 95% confidence interval [CI], 0.07‒0.49; P<0.001), higher-risk mutations (compared with no mutation; HR, 5.51; 95% CI, 1.61‒18.84; P=0.007), and lower-risk mutations (compared with no mutation; HR, 3.70; 95% CI, 1.05‒13.02; P=0.04). Conclusions: The TMA event rate was 2.7-fold higher after eculizumab discontinuation compared with patients receiving ongoing eculizumab therapy. TMA event rates were lowest during on-label dosing, higher during reduced dosing, and highest during off-treatment periods. These findings suggest that patients with aHUS have a progressive increase in the risk of TMA events during periods of reduced dosing and after discontinuation of eculizumab, compared with on-label eculizumab dosing.

Background: Multiple myeloma (MM) is common among the elderly, with 35% of patients (pts) diagnosed being aged ≥75 years (y). With increasing overall life expectancy, the incidence and prevalence of newly diagnosed and previously treated MM patients ≥80 y is expected to increase over time. Because elderly pts are often excluded from clinical trials, data focused on their treatment patterns and clinical outcomes are lacking. The Connect® MM Registry (NCT01081028) is a large, US, multicenter, prospective observational cohort study of pts with newly diagnosed MM (NDMM) designed to examine real-world diagnostic patterns, treatment patterns, clinical outcomes, and health-related quality of life patient-reported outcomes. This analysis reviews treatment patterns and outcomes in elderly pts from the Connect MM Registry. Methods: Pts enrolled in the Connect MM registry at 250 community, academic, and government sites were included in this analysis. Eligible pts were adults aged ≥18 y with symptomatic MM diagnosed ≤2 months before enrollment, as defined by International Myeloma Working Group criteria; no exclusion criteria were applied. For this analysis, pts were categorized into 4 age groups: <65, 65 to 74, 75 to 84, and ≥85 y. Pts were followed from time of enrollment to the earliest of disease progression (or death), loss to follow-up, or data cutoff date of February 7, 2019. Descriptive statistics were used for baseline characteristics and treatment regimens. Survival outcomes were analyzed using Cox regression. Time to progression (TTP) analysis excluded causes of death not related to MM. Results: Of 3011 pts enrolled (median age 67 y), 132 (4%) were aged ≥85 y, and 615 (20%) were aged 75-84 y at baseline. More pts aged ≥85 y had poor prognostic factors such as ISS stage III disease and reduced hemoglobin (<10 g/dL or >2 g/dL <LLN) compared with other age groups, although no notable differences between creatinine and calcium levels were observed across age groups (Table). A lower proportion of elderly pts (75-84 and ≥85 y) received triplet regimens as frontline therapy. More elderly pts received a single novel agent, whereas use of 2 novel agents was more common in younger pts (Table). The most common frontline regimens among elderly pts were bortezomib (V) + dexamethasone (D), followed by lenalidomide (R) + D, whereas those among younger pts included RVD, followed by VD and CyBorD (Table). No pt aged ≥85 y, and 4% of pts aged 75-84 y received high-dose chemotherapy and autologous stem cell transplant (vs 61% in the <65 y and 37% in the 65-74 y age group). The most common maintenance therapy was RD in pts ≥85 y (although the use was low) and R alone in other age groups (Table). In the ≥85 y group, 27%, 10%, and 4% of pts entered 2L, 3L, and 4L treatments respectively, vs 43%, 23%, and 13% in the <65 y group. Progression-free survival was significantly shorter in the ≥85 y age group vs the 75-84 y age group (P=0.003), 65-74 y age group (P<0.001), and <65 y age group (P<0.001; Fig.1). TTP was significantly shorter in the ≥85 y group vs the <65 y group (P=0.020); however, TTP was similar among the 65-74 y, 75-84 y, and ≥85 y cohorts (Fig. 2). Overall survival was significantly shorter in the ≥85 y group vs the 75-84 y, 65-74 y, and <65 y groups (all P<0.001; Fig. 3). The mortality rate was lowest (46%) during first-line treatment (1L) in pts aged ≥85 y (mainly attributed to MM progression) and increased in 2L and 3L (47% and 54%, respectively); a similar trend was observed in the younger age groups. The main cause of death was MM progression (29% in the ≥85 y vs 16% in the <65 y group). Other notable causes of death in the ≥85 y group included cardiac failure (5% vs 2% in <65 y group) and pneumonia (5% vs 1% in <65 y group). Conclusions: In this analysis, elderly pts received similar types of frontline and maintenance regimens as younger pts, although proportions varied with decreased use of triplet regimens with age. Considering similarities in TTP across the 65-74 y, 75-84 y, and ≥85 y cohorts, these real-world data support active treatment and aggressive supportive care of elderly symptomatic pts, including with novel agents. Additionally, further clinical studies specific to elderly patients with MM should be explored.

Background Transfusion-dependent β-thalassemia (TDT) is treated with regular, lifelong red blood cell (RBC) transfusions and despite iron-chelating therapy, carries a risk of serious organ damage from iron overload and other complications. Transplantation with autologous CD34+ cells encoding a βA-T87Q-globin gene (LentiGlobin for β-thalassemia) is being evaluated in patients with TDT. Interim results are presented here from the ongoing, international, single-arm, phase 3 Northstar-2 study (HGB-207; NCT02906202) of LentiGlobin gene therapy in pediatric, adolescent, and adult patients with TDT (defined by receiving ≥100 mL/kg/yr of RBCs or ≥8 RBC transfusions/yr) and non-β0/β0 genotypes. Methods Patients undergo hematopoietic stem cell (HSC) mobilization with G-CSF and plerixafor. Following apheresis, CD34+ cells are transduced with BB305 lentiviral vector and infused into patients after pharmacokinetic-adjusted, single-agent busulfan myeloablation. The primary efficacy endpoint is transfusion independence (TI; weighted average hemoglobin [Hb] ≥9 g/dL without RBC transfusions for ≥12 months). HSC engraftment, βA-T87Q-globin expression, Hb levels, detection of replication competent lentivirus (RCL), and adverse events (AE) are also assessed. Patients are followed for 2 years and offered participation in a long-term follow-up study. Summary statistics are presented as median (min - max). Results Twenty patients were treated in Northstar-2 as of 13 December 2018 and have been followed for a median of 8.1 (0.5 - 22.2) months. At enrollment, median age was 16 (8 - 34) years; 5 patients were <12 years of age. Median drug product cell dose was 8.0 (5.0 - 19.9) x106 cells/kg and vector copy number was 3.2 (1.9 - 5.6) copies/diploid genome. Time to neutrophil and platelet engraftment in the 18/20 and 15/20 evaluable patients was 22.5 (13 - 32) and 45 (20 - 84) days, respectively. Non-hematologic grade ≥3 AEs in ≥3 patients after LentiGlobin infusion included stomatitis (n=12), febrile neutropenia (n=6), pyrexia (n=4), epistaxis (n=3), and veno-occlusive liver disease (n=3). One serious AE of grade 3 thrombocytopenia was considered possibly related to LentiGlobin. No patient died, had graft failure, or had detection of RCL. No insertional oncogenesis has been observed. Gene therapy-derived HbAT87Q stabilized approximately 6 months after infusion. In adolescent and adult patients treated with LentiGlobin, median HbAT87Q at Months 6, 12 and 18 was 9.5 (n=11), 9.2 (n=8), and 9.5 (n=3) g/dL, respectively. The median total Hb without transfusions at Months 6, 12, and 18 were 11.9 (n=11), 12.4 (n=8), 12.3 (n=2) g/dL, respectively. At Month 6, 91% (10/11) of patients had total Hb of >11 g/dL without transfusions. Five adolescent and adult patients were evaluable for the primary endpoint of transfusion independence, 4 (80%) of whom achieved TI. The median weighted average Hb during TI was 12.4 (11.5 - 12.6) g/dL which compared favorably to pre-transfusion nadir Hb levels before enrollment (median 9.1 g/dL [7.5 - 10.0 g/dL]). At time of analysis, the median duration of TI was 13.6 (12.0 - 18.2) months. One patient who did not achieve TI stopped transfusions for 11.4 months but resumed transfusions due to recurrent anemia. This patient had a 71.4% reduction in RBC transfusion volume from Month 6 to Month 18 compared to baseline. Marrow cellularity and myeloid:erythroid (M:E) ratios were evaluated in 8 adolescent and adult patients with ≥12 months follow-up to assess the effect of LentiGlobin treatment on dyserythropoiesis. Seven of 8 patients had improved marrow M:E ratios at Month 12 (0.63 - 1.90) compared with baseline (0.14 - 0.48). In patients who stopped transfusions, soluble transferrin receptor levels were reduced by a median of 72% (58% - 78%) at Month 12 (n=6). Updated outcomes in adolescents and adults and outcomes in pediatric patients will be reported. Summary In this update of the Northstar-2 study of LentiGlobin gene therapy in patients with TDT and non-β0/β0 genotypes, transfusion independence was observed in 4/5 evaluable adolescent and adults and 10/11 treated patients had total Hb of >11 g/dL without transfusion support 6 months after LentiGlobin infusion. HbAT87Q stabilized approximately 6 months after treatment and patients who stopped RBC transfusions had improved erythropoiesis. A safety profile consistent with busulfan conditioning was observed after LentiGlobin gene therapy.

Abstract Abstract 2085 Introduction. Although advanced patient age is commonly used as a factor in selecting therapy for patients with chronic lymphocytic leukemia (CLL), based on presumed associations with functional status, limited data exist regarding the relationships between age and physical, emotional, social, and functional well being. We examined the relationships between age and these domains of health-related quality of life (HRQOL) for CLL patients treated in US community practices. Methods. Baseline data were collected as part of Connect CLL®, a prospective observational registry initiated in March 2010 involving centers in the US. Data on patient demographics and clinical characteristics were provided by clinicians. HRQOL was self-reported by patients in the clinic at enrollment. Patients completed 3 psychometrically validated instruments: the Brief Fatigue Inventory (BFI), EQ-5D, and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu). Standard analyses were conducted of each instrument given clinical characteristics at that time. Reported mean BFI, EQ-5D and FACT-Leu scores were analyzed by age group (<65, 65–74, >74). Statistical significance of score differences among sub-cohorts was ascertained by ANOVA using SAS 9.1. Results. Baseline HRQOL data were reported by 604 patients, enrolled from 161 centers. Patients were predominantly male (62%) and white (90%) with mean age at 69.9 (standard deviation [SD] 11.2) yrs. HRQOL scores by age group are presented: There were no significant differences between the age groups in fatigue as measured by the BFI, or differences in overall HRQOL as measured by the EQ-5D Visual Analogue Scale (VAS) or the FACT-G. Anxiety/depression and self care are EQ-5D domains that also did not vary by age. Although mobility was most impaired in the oldest age group compared to the two younger groups, usual activities and pain/discomfort were worse in both the younger and older cohorts compared to those 65–74 years of age. FACT-Leu results indicated that the social/family domain scores did not vary by age, but that physical, emotional, and functional domains did vary statistically with the oldest typically doing better than the 65–74 year olds, but not necessarily better than those <65. Conclusions. Initial results from the Connect CLL® Registry indicate that HRQOL does not worsen monotonically with older age. In this cohort, both the youngest and oldest age groups had worse HRQOL in certain domains, presenting an inverted v-shaped relationship. Future analyses should be conducted on: (1) how HRQOL may be affected over time with changes in disease; and, (2) how HRQOL may be influenced by alternative therapies. Results reported here should serve as a useful baseline reference. Disclosures: Pashos: Celgene: Membership on an entity's Board of Directors or advisory committees.

Abstract Introduction:Atypical hemolytic uremic syndrome (aHUS) is a rare, genetic, life-threatening disease of chronic, uncontrolled complement activation leading to thrombotic microangiopathy, renal, and other end-organ damage. Started in April 2012, the aHUS Registry is an observational, non-interventional, multicenter, global registry designed to collect information on patients (pts) with aHUS. By making follow-up data on the aHUS indication for eculizumab (ECU) available, the Registry fulfills postmarketing regulatory requirements while also highlighting the need for and benefit of a sponsor/academia partnership. An independent Scientific Advisory Board ensures data are made accessible for publication. Herein, we report baseline demographics and clinical characteristics of pts enrolled in the aHUS Registry. Methods:Pts of all ages with a clinical diagnosis of aHUS (irrespective of treatment) are eligible for enrollment into the Registry. An identified complement abnormality is not required. Demographic, medical and disease history, treatment, and efficacy and safety outcomes data are collected at Registry enrollment and prospectively thereafter. Results:By July 1, 2014, 466 pts (from Australia, Austria, Belgium, Canada, France, Germany, Israel, Italy, Russia, Spain, Sweden, Switzerland, the UK, and USA) were enrolled in the aHUS Registry. Of these, 261 (56.0%) were treated with ECU and 286 (61.4%) were ≥18 years of age. Family history of aHUS, prior kidney grafts, dialysis, plasma exchange/plasma infusion (PE/PI), and renal impairment were assessed at baseline in ECU- and non–ECU-treated pts (Table). Mean time from aHUS diagnosis to ECU initiation was 2.5 years. Sixty-five pts (24.9%) discontinued ECU; of these, 8 (12.3%) restarted. Conclusions:Since the public disclosure of data from the last aHUS Registry update, pt enrollment has continued to increase. Ongoing and future analyses will further clinicians’ understanding of the history and progression of aHUS. Additional clinical sites are encouraged to enroll pts into the aHUS Registry to facilitate knowledge acquisition and optimization of pt care and quality of life.

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.

Abstract Abstract 2102 Background: Paroxysmal nocturnal hemoglobinuria (PNH) is a chronic, life-threatening hematopoietic stem cell disorder characterized by deficiency of the GPI-anchored complement inhibitory proteins CD55 and CD59. Uncontrolled complement activation is responsible for chronic hemolysis that leads to the serious clinical morbidities including thromboembolism (TE) and chronic kidney disease, which increase risk of mortality. PNH is infrequent in children and as such, there is a paucity of data in the literature examining their burden of disease. This is the largest series of pediatric patients with PNH, and the first comparison with adult PNH patients. AIM: To assess the clinical differences between pediatric and adult PNH patients with classic/hemolytic PNH. Methods: Data from 1143 PNH patients from 204 clinical sites in 21 countries on 5 continents (as of 6/30/11) were analyzed to evaluate clinical characteristics of PNH. Patients registered as having classic/hemolytic PNH were initially included (n=559). Of these, 62 additional patients were excluded due to either a <30% granulocyte clone size, or missing data on enrollment date, date of birth, sex, date of disease start and history of TE. The final population for this study was 497 patients, classified into two groups, those first diagnosed at age <18 years (pediatric patients N=49) and at age ≥18 years (adult patients N=448). Baseline demographics, laboratory values, PNH-related medical history, and physician-reported PNH symptoms were compared for pediatric and adult patients. Patients/guardians gave informed consent prior to enrollment. Results: The median age at disease start for pediatric patients was 15 years (5–17), and for adults was 33 years (18–87). Hemoglobin, leucocytes, neutrophils, reticulocytes, LDH, and number of transfusions were similar between both pediatric and adult patients. There were no differences in GPI-deficient granulocyte or RBC clone sizes between pediatric and adult patients. Follow-up was longer for children (mean + SD, in years: 14.5 + 13.6 vs 9.6 + 9.1, P<0.001, respectively). The number of pediatric and adult patients receiving concomitant medications such as anticoagulants (peds 49% vs adults 54.9%; P=0.43) and eculizumab (peds 40.8% vs adults 45.5%; P=0.53) prior to enrollment were similar. No differences between pediatric and adult patients were observed in bone marrow disorders, renal impairment, hemoglobinuria, abdominal pain, dysphagia, headache and shortness of breath. In contrast, pediatric patients reported less fatigue (57.1% vs. 76.8%; P=0.001). TE incidence was 12.2% for pediatric and 23.9% for adults, which was statistically significant when the length of the time of exposure to this complication was taken into account; TE event rate was significantly lower in pediatric patients compared to adults (1.0/100 pt-yrs vs 4.4/100 pt-yrs; P<0.001 by Poisson regression). Patients with TE had a mean granulocyte clone size of 85.7% vs 81.0% for patients without TE (P=0.026). Both in children and adults the risk of TE was much higher than expected for the general population (general pediatric population: TE incidence is 0.07 per 10,000 or 0.0007%, vs 12.2% in this study). TE events at venous sites (hepatic/portal, mesenteric/visceral, renal, and cerebral veins) and arterial sites were less frequent in pediatric patients compared to adults. The most striking difference in TE type was thrombophlebitis/deep vein thrombosis, which occurred significantly less frequently in pediatric than adult patients (2.0% vs 11.8%; p=0.037). In multivariate analysis, age >18 years at disease onset and kidney disease were predictors of TE (odds ratio [OR] 3.01, 95% CI 1.15–7.72; P=0.02, and OR 1.87, 95% CI 1.03–3.4; P=0.04, respectively), while clone size was not a significant predictor of TE (OR 1.010, 95% CI 0.995–1.025; P=0.18). Conclusions: Pediatric PNH patients experience a significant burden of disease similar to adult PNH patients. There were no differences in LDH levels, GPI-deficient clone size, or in the incidence of bone marrow disorders, renal impairment, hemoglobinuria, abdominal pain, shortness of breath and dysphagia between pediatric and adult patients. TE event rate was lower in pediatric PNH patients when compared to adults, especially for those with concomitant kidney disease However, TE still remains an issue in this population and pediatric PNH patients are at significant risk for TE.

Background Granulocyte colony-stimulating factor (G-CSF) is the standard of care for mobilization of hematopoietic stem cells (HSCs). G-CSF requires 4-7 days of injections and often multiple aphereses to acquire sufficient CD34+ cells for transplant. The number of CD34+ HSCs mobilized can be variable and patients who fail to mobilize enough CD34+ cells are treated with the combination of G-CSF plus plerixafor. G-CSF use is associated with bone pain, nausea, headaches, fatigue, rare episodes of splenic rupture, and is contraindicated for patients with autoimmune and sickle cell disease. MGTA-145 (GroβT) is a CXCR2 agonist. MGTA-145, in combination with plerixafor, a CXCR4 inhibitor, has the potential to rapidly and reliably mobilize robust numbers of HSCs with a single dose and same-day apheresis for transplant that is free from G-CSF. MGTA-145 plus plerixafor work synergistically to rapidly mobilize HSCs in both mice and non-human primates (Hoggatt, Cell 2018; Goncalves, Blood 2018). Based on these data, Magenta initiated a Phase 1 dose-escalating study to evaluate the safety, PK and PD of MGTA-145 as a single agent and in combination with plerixafor. Methods This study consists of four parts. In Part A, healthy volunteers were dosed with MGTA-145 (0.0075 - 0.3 mg/kg) or placebo. In Part B, MGTA-145 dose levels from Part A were selected for use in combination with a clinically approved dose of plerixafor. In Part C, a single dose MGTA-145 plus plerixafor will be administered on day 1 and day 2. In Part D, MGTA-145 plus plerixafor will be administered followed by apheresis. Results MGTA-145 monotherapy was well tolerated in all subjects dosed (Table 1) with no significant adverse events. Some subjects experienced mild (Grade 1) transient lower back pain that dissipated within minutes. In the ongoing study, the combination of MGTA-145 with plerixafor was well tolerated, with some donors experiencing Grade 1 and 2 gastrointestinal adverse events commonly observed with plerixafor alone. Pharmacokinetic (PK) exposure and maximum plasma concentrations increased dose proportionally and were not affected by plerixafor (Fig 1A). Monotherapy of MGTA-145 resulted in an immediate increase in neutrophils (Fig 1B) and release of plasma MMP-9 (Fig 1C). Neutrophil mobilization plateaued within 1-hour post MGTA-145 at doses greater than 0.03 mg/kg. This plateau was followed by a rebound of neutrophil mobilization which correlated with re-expression of CXCR2 and presence of MGTA-145 at pharmacologically active levels. Markers of neutrophil activation were relatively unchanged (<2-fold vs baseline). A rapid and statistically significant increase in CD34+ cells occurred @ 0.03 and 0.075 mg/kg of MGTA-145 (p < 0.01) relative to placebo with peak mobilization (Fig 1D) 30 minutes post MGTA-145 (7-fold above baseline @ 0.03 mg/kg). To date, the combination of MGTA-145 plus plerixafor mobilized >20/µl CD34s in 92% (11/12) subjects compared to 50% (2/4) subjects receiving plerixafor alone. Preliminary data show that there was a significant increase in fold change relative to baseline in CD34+ cells (27x vs 13x) and phenotypic CD34+CD90+CD45RA- HSCs (38x vs 22x) mobilized by MGTA-145 with plerixafor. Mobilized CD34+ cells were detectable at 15 minutes with peak mobilization shifted 2 - 4 hours earlier for the combination vs plerixafor alone (4 - 6h vs 8 - 12h). Detailed results of single dose administration of MGTA-145 and plerixafor given on one day as well as also on two sequential days will be presented along with fully characterized graft analysis post apheresis from subjects given MGTA-145 and plerixafor. Conclusions MGTA-145 is safe and well tolerated, as a monotherapy and in combination with plerixafor and induced rapid and robust mobilization of significant numbers of HSCs with a single dose in all subjects to date. Kinetics of CD34+ cell mobilization for the combination was immediate (4x increase vs no change for plerixafor alone @ 15 min) suggesting the mechanism of action of MGTA-145 plus plerixafor is different from plerixafor alone. Preliminary data demonstrate that MGTA-145 when combined with plerixafor results in a significant increase in CD34+ fold change relative to plerixafor alone. Magenta Therapeutics intends to develop MGTA-145 as a first line mobilization product for blood cancers, autoimmune and genetic diseases and plans a Phase 2 study in multiple myeloma and non-Hodgkin lymphoma in 2020.

Introduction: For patients with newly diagnosed multiple myeloma (NDMM) who are transplant-eligible, bortezomib/thalidomide/dexamethasone (VTd) is a standard of care (SoC) for induction and consolidation therapy. Clinical practice has evolved to use a modified VTd dose (VTd-mod; 100 mg thalidomide daily), which is reflected in recent treatment guidelines. As VTd-mod has become a real-world SoC, a matching-adjusted indirect comparison (MAIC) of the VTd-mod dose from recent clinical trials versus the dose included in the label (VTd-label; ramp up to 200 mg thalidomide daily) was performed to understand the effect on efficacy of modified VTd dosing for patients with NDMM who are transplant-eligible. Methods: For each outcome (overall survival [OS], progression-free survival [PFS], overall response rates [ORR] post-induction and post-transplant, and rate of peripheral neuropathy), a naïve comparison and a MAIC were performed. Data for VTd-label were obtained from the phase 3 PETHEMA/GEM study (Rosiñol L, et al. Blood. 2012;120[8]:1589-1596). Data for VTd-mod were pooled from the phase 3 CASSIOPEIA study (Moreau P, et al. Lancet. 2019;394[10192]:29-38) and the phase 2 NCT00531453 study (Ludwig H, et al. J Clin Oncol. 2013;31[2]:247-255). Patient-level data for PETHEMA/GEM and CASSIOPEIA were used to generate outcomes of interest and were validated against their respective clinical study reports; aggregate data for NCT00531453 were extracted from the primary publication. Matched baseline characteristics were age, sex, ECOG performance status, myeloma type, International Staging System (ISS) stage, baseline creatinine clearance, hemoglobin level, and platelet count. Results: Patients received VTd-mod (n = 591) or VTd-label (n = 130). After matching, baseline characteristics were similar across groups. For OS, the naïve comparison and the MAIC showed that VTd-mod was non-inferior to VTd-label (MAIC HR, 0.640 [95% CI: 0.363-1.129], P = 0.121; Figure 1A). VTd-mod significantly improved PFS versus VTd-label in the naïve comparison and MAIC (MAIC HR, 0.672 [95% CI: 0.467-0.966], P = 0.031; Figure 1B). Post-induction ORR was non-inferior for VTd-mod versus VTd-label (MAIC odds ratio, 1.781 [95% CI: 1.004-3.16], P = 0.065). Post-transplant, VTd-mod demonstrated superior ORR in both the naïve comparison and MAIC (MAIC odds ratio, 2.661 [95% CI: 1.579-4.484], P = 0.001). For rates of grade 3 or 4 peripheral neuropathy, the naïve comparison and MAIC both demonstrated that VTd-mod was non-inferior to VTd-label (MAIC rate difference, 2.4 [⁻1.7-6.49], P = 0.409). Conclusions: As naïve, indirect comparisons are prone to bias due to patient heterogeneity between studies, a MAIC can provide useful insights for clinicians and reimbursement decision-makers regarding the relative efficacy and safety of different treatments. In this MAIC, non-inferiority of VTd-mod versus VTd-label was demonstrated for OS, post-induction ORR, and peripheral neuropathy. This analysis also showed that VTd-mod significantly improved PFS and ORR post-transplant compared with VTd-label for patients with NDMM who are transplant-eligible. A limitation of this analysis is that unreported or unobserved confounding factors could not be adjusted for.

Steroid Refractory

Abstract Background: Corticosteroids are considered standard first-line systemic therapy for patients with aGVHD, but this approach is effective in only approximately half of all cases. For patients who progress or do not respond to corticosteroids, no specific agent has been identified as standard, and regimens are typically selected based on investigator experience and patient co-morbidities. In preclinical models, JAK inhibition has been shown to impair production of cytokines as well as the differentiation and trafficking of T cells implicated in the pathogenesis of aGVHD. Retrospective studies have suggested that JAK1/JAK2 inhibition with ruxolitinib treatment provides clinical benefit in patients with steroid-refractory GVHD (Zeiser et al, Leukemia 2015;29:2062-2068). Herein, we report preliminary safety results from a prospective randomized, parallel-cohort, open-label phase 1 trial evaluating the potent and selective JAK 1 inhibitor INCB039110 in patients with aGVHD. Methods: Male or female patients 18 years or older who underwent their first allo-hematopoietic stem cell transplant (HSCT) from any donor source and developed grades IIB-IVD aGVHD were eligible for the study. Patients were randomized 1:1 to either a 200 or 300 mg oral daily dose of INCB039110 in combination with corticosteroids, and were stratified based on prior treatment status (treatment-naive [TN] versus steroid-refractory [SR]). The primary endpoint of the study was safety and tolerability; secondary endpoints included overall response rate at Days 14, 28, 56, and 100, non-relapse mortality, and pharmacokinetic (PK) evaluations. Patients were assessed through Day 28 for dose-limiting toxicities (DLTs) and response. A Bayesian approach was used for continuous monitoring of DLTs from Days 1-28. Treatment continued until GVHD progression, unacceptable toxicity, or withdrawal from the study. Acute GVHD was graded according to MN-CIBMTR criteria; adverse events (AEs) were graded according to NCICTCAE v 4.03. Results: Between January and June 2016, 31 patients (TN, n=14; SR, n= 17) were randomized. As of July 25, 2016, data were available from 30 patients who received an oral daily dose of 200 mg (n=14) or 300 mg (n=16) INCB039110 in combination with 2 mg/kg methylprednisolone (or equivalent dose of prednisone). The median durations of treatment were 60.8 days and 56.5 days for patients receiving a daily dose of 200 mg and 300 mg INCB039110, respectively. One DLT of Grade 3 thrombocytopenia was reported. The most frequently reported AEs included thrombocytopenia/platelet count decrease (26.7%), diarrhea (23.3%), peripheral edema (20%), fatigue (16.7%), and hyperglycemia (16.7%). Grade 3 or 4 AEs occurred in 77% of patients and with similar frequency across dose groups and included cytomegalovirus infections (n=3), gastrointestinal hemorrhage (n=3), and sepsis (n=3). Five patients had AEs leading to a fatal outcome, including multi-organ failure (n=2), sepsis (n=1), disease progression (n=1), and bibasilar atelectasis, cardiopulmonary arrest, and respiratory distress (n=1); none of the fatal events was attributed to INCB039110. Efficacy and PK evaluations are ongoing and will be updated at the time of presentation. Conclusion: The oral, selective JAK1 inhibitor INCB039110 can be given safely to steroid-naive or steroid-refractory aGVHD patients. The safety profile was generally consistent in both dose groups. Biomarker evaluation, PK, and cellular phenotyping studies are ongoing. The recommended phase 2 dose will be selected and reported based on PK studies and final safety data.
