Characterization of Real World Treatment Patterns and Outcomes Among Older Adults with Chronic Lymphocytic Leukemia in the Pre Novel-Agents Era: An Analysis of the 2007-2013 SEER-Medicare Database

Abstract Background: Chronic lymphocytic leukemia (CLL) is the most common leukemia among adults in Western countries with a median age of 72 years at diagnosis. Data from recent randomized clinical trials of novel agents, such as ibrutinib, have shown significant improvements in overall survival (OS) among older CLL patients. Prior to the introduction of kinase inhibitor therapies, chemoimmunotherapy combinations were the mainstay treatment. However, older individuals and/or those with co-morbid conditions may be less likely to tolerate standard CLL chemoimmunotherapy. While we await real-world outcomes data on how novel agents have continued to change the CLL landscape, little is known about the management and survival among older CLL patients prior to the availability of novel agents in clinical practice. Our study uses comprehensive prescription and medical insurance claims linked with registry data to describe the time to treatment initiation, front line therapy, and survival outcomes in older adults with CLL between 2007-2013--an era that predates the approvals of ibrutinib, idelalisib and obinutuzumab. Methods: The study used the 2007 to 2013 SEER-Medicare linked database. The sample included patients with first primary tumor site as CLL or SLL (ICD-O histology codes 9670 and 9823) diagnosed between 2007 and 2011. This date of first diagnosis of CLL or SLL defines the index date. Patients aged > 65 years with Medicare fee-for-service coverage in the 12 months pre-index and Medicare fee-for-service and prescription drug coverage in the 6-months post-index period or until death were included. Study outcomes included time to first treatment since CLL/SLL diagnosis, type of treatment initiated, and OS since first treatment. The first treatment type was classified into 6 groups (rituximab monotherapy, chlorambucil monotherapy, rituximab + bendamustine, rituximab + fludarabine +/- other treatment, rituximab + other chemotherapy, and other chemotherapy without rituximab). Logistic regression examined factors associated with receiving any treatment within 1- and 2-years of diagnosis. Cox regression examined factors associated with OS. Covariates in both sets of models included age, gender, race, region, low-income subsidy status, anemia/thrombocytopenia at diagnosis, comorbidities, disability status, and year of diagnosis. Cox regressions also included covariates for time to treatment and type of first treatment. Results: We identified 3,214 newly diagnosed CLL/SLL patients. Our sample had a mean age of 78 years (SD: 8), 49% were male, and 30% had anemia and/or thrombocytopenia at diagnosis. Nearly 33% of the patients received at least one CLL treatment over a median follow-up of 1,099 days (IQR: 834-1735 days) from the date of diagnosis. The most common treatments were rituximab monotherapy (26%), fludarabine + rituximab +/- other treatment (23%), and chlorambucil monotherapy (16%). Among those who initiated treatment, the median time to initiation was 791 days (IQR: 127-1344 days) from diagnosis. Logistic regressions indicated that patients aged 75-79 years old (vs. 80+ year olds) and those with anemia and/or thrombocytopenia at diagnosis were significantly more likely to initiate treatment within 1- and 2-years of diagnosis. The median OS from treatment initiation among the 1,047 treated patients was 52.4 months (Figure 1). The estimated 1-year and 2-year OS since treatment initiation was 81% and 69%, respectively. The OS at 2 years was 68% for rituximab monotherapy, 73% for fludarabine + rituximab +/- other treatment, and 59% for chlorambucil monotherapy. Cox regressions showed older age, male gender, disability, higher comorbidity scores, and type of first treatment (chlorambucil monotherapy vs. rituximab as monotherapy or in combination with chemotherapies) to be significantly associated with lower OS. Discussion: About one-third of older individuals who were newly diagnosed with CLL initiated treatment over a median follow-up of 3 years. This real world study shows modest 2-year OS in older CLL patients after initiating treatment in the pre-novel therapy era. While available clinical trials suggest novel CLL agents offer significant improvements in survival for older adults with CLL, future studies should examine CLL outcomes in real world settings to correlate how results obtained in recent landmark clinical trials translate into clinical practice.

Background Blinatumomab is a bispecific T cell antibody construct, that binds and allows CD-3 positive cytotoxic T cells to recognize and eradicate CD19-positive acute lymphocytic leukemia (ALL) blasts. The drug is approved for patient (pts) with relapsed/ refractory (RR) B-cell ALL and those with minimal residual disease (MRD) based on efficacy in clinical trials. We sought to evaluate the safety and efficacy of blinatumomab in the "real world" setting. Methods We conducted a retrospective multicenter study in collaboration with 11 U.S. academic institutions, and evaluated the outcome of RR B-cell ALL pts, who received blinatumomab outside of clinical trials. These pts were evaluated for response, duration of response (DOR), overall survival (OS) from the time of blinatumomab initiation and toxicity. DOR was estimated among pts who had achieved complete remission (CR)/CR with incomplete count recovery (CRi). Survival curves were estimated using the Kaplan-Meier method and compared via log-rank test. Results From December 2014 to May 2019, 239 pts with B-cell ALL were identified. Baseline characteristics are summarized in Table 1. The median age of pts at blinatumomab initiation was 48 years (yrs) (range, 18-85). Sixty-one (26%) pts had Philadelphia chromosome [t(9;22)] positive (Ph+ve) disease. Sixty-one (26%) pts had ≥ 3 prior therapies and 46 (19%) pts had allogeneic stem cell transplantation (allo-HCT) prior to blinatumomab. Twenty-two (9%) pts received inotuzumab ozagamicin prior to blinatumomab. Twenty-nine (12%) pts received blinatumomab in combination with tyrosine kinase inhibitor (TKI). Twelve (5%) pts received blinatumomab for MRD. Response rate (CR/CRi) in pts with RR disease was 61%; 44% had CR with MRD negativity by flow cytometry. Rate of CR/CRi in Ph+ve B-cell ALL was 74.5%. Among 12 pts who received Blinatumomab for MRD, 9 (75%) pts achieved MRD negativity. Overall 113 (48%) pts were successfully bridged to allo-HCT. Median DOR in pts with RR disease was 32.1 months (95% CI; 9.5-not reached [NR]) (Fig. 1a) and when censored at allo-HCT was 14.8 months (95% CI; 5.2-NR) (Fig. 1b). Median OS in pts with RR disease after blinatumomab was 12.7 months (95% CI; 9.2 -17.9) (Fig. 1c) and when censored at allo-HCT was 8.6 months (95% CI; 6.4-11.6) (Fig.1d). Median OS after blinatumomab in RR B-cell ALL Ph+ve pts was NR (59% alive at 2 yr). Among pts who received blinatumomab for MRD, median DOR was NR and 54% sustained MRD negativity at 2 yrs. Median OS was 34.7 months (95% CI; 8.8-34.7) in group of pts who received blinatumomab for MRD. Seven (3%) pts discontinued blinatumomab due to adverse events and 40 (21%) pts had dose interruptions. Cytokine release syndrome (CRS) of any grade (G) was reported in higher number of pts (93 [39%]) compared to clinical trials, though G3-4 CRS appears to be similar (G1-2 [36%], G3-4 [3%]). Forty-four (44%) pts were treated with steroids and 8 (8%) pts required tocilizumab with steroids for CRS. Ninety-three percent of pts had complete resolution of CRS. CNS toxicities were observed in 31 (13%) pts, among them 60% (n= 19) had G3-4 toxicities. Hepatic toxicities were observed in 84 (35%) pts as outlined in Table 1. Six (2.5%) pts died due to blinatumomab induced toxicities. Conclusion: Our real-world data with multicenter collaboration suggest that overall blinatumomab was well tolerated and had led to significant response in pts with RR B-cell ALL.

Abstract Introduction: Chronic lymphocytic leukemia (CLL) is the most common leukemia among adults in Western countries with a median age of 72 years at diagnosis. Prior to the introduction of kinase inhibitor therapies, chemoimmunotherapy (CIT) combinations, monoclonal antibody monotherapies, and chemotherapy combinations were the predominant therapy regardless of line of CLL treatment. Given the increased frequency of high-risk features (del17p, del11q,) and prior exposure to CIT combinations, shortened disease-free periods and increased short-/long-term toxicities are frequently seen in relapsed CLL setting. However, data from recent randomized clinical trials of novel agents, such as ibrutinib in the relapsed setting, have shown significant improvements in overall survival (OS). While we await real-world data on how novel agents impact real-world CLL outcomes, little is known about the management and survival among CLL patients prior to their availability, particularly in the relapse setting. Our study uses comprehensive prescription and medical insurance claims linked with registry data to describe survival outcomes in older adults with CLL receiving second line treatment between 2007-2013--an era that predates the approvals of ibrutinib, idelalisib, venetoclax and obinutuzumab. Methods: This retrospective cohort study used the 2007 to 2013 SEER-Medicare linked database. The sample included patients with first primary tumor site as CLL or SLL (ICD-O histology codes '9670' and '9823') diagnosed between 2007 and 2011. This date of first diagnosis of CLL or SLL defines the index date. Patients aged > 65 years with Medicare fee-for-service coverage in the 12 months pre-index and Medicare fee-for-service and prescription drug coverage in the 6-months post-index period or until death were included. Second line treatment date was defined as the date a treatment was received that was not part of the initial therapy or the date where initial therapy was restarted after a 180+ day gap in treatment. Our primary study outcome was overall survival (OS) from the date of initiation of second line treatment. The association of patient-level characteristics with OS was measured using cox regression analysis. Results: Of the 1047 patients who received any CLL treatment, 387 (37%) patients met the definition for receiving a second line of therapy. The mean age of this second line cohort was 76 years (SD = 6) and 48.3% were male. Only 9 patients who left fee-for-service Medicare during the second line follow up period were excluded from analysis. Of our 387 patient cohort, 25.3% (n=98) received fludarabine as part of their initial treatment, with remaining 74.7% (n=289) receiving a non-fludarabine containing initial therapy. The median time from CLL diagnosis date to second treatment was 664 days (Q1-Q3 390-1159 days). Rituximab containing regimens were the most common second line treatment (n=276, 71.3% of patients), with 118 patients (30.5%) in our second line cohort receiving rituximab monotherapy. Another 35 (9%) patients received chlorambucil monotherapy and the remaining 76 (19.6%) patients received a non-rituximab mono- or combination chemotherapy as their second line treatment. The median follow-up time in the sample from second line treatment was 14.9 months. Median OS for the cohort from initiation of their second line of treatment was 34.3 months, with 72% OS at 1-year and 58% at 2-years (See Figure). Multivariate Cox regression modeling showed OS from second line of treatment was associated with year of CLL diagnosis (2011 vs. 2007, HR 2.2; p=0.02), higher age at time of treatment (70-74 vs 80+, HR 0.67; P=0.04), male gender (HR 1.5; P=0.01), Northeast census region (vs West, HR 1.7; P=0.01),and initial treatment that included fludarabine (HR 1.5; P=0.04). Conclusions: In our real world analysis, over one-third of the newly diagnosed CLL patients who received treatment progressed to second line therapy. We found poor survival in these older adults following initiation of second line CLL therapy treated in the pre-kinase / BCL-2 inhibitor era with about half who died within two years of initiating second line therapy. While available clinical trials suggest novel CLL agents offer significant improvements in OS in relapsed CLL, future studies should examine real world CLL outcomes to correlate how results obtained in recent landmark clinical trials translate into clinical practice.

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 Background Ofatumumab was given a conditional approval in the EU on April 2010 for the treatment of CLL refractory to fludarabine (F-ref) and alemtuzumab (A-ref), encouraging the retrieval of further data in patients treated in a “daily life” setting and to investigate treatment safety. Aims The main objective of this study was to obtain information on the safety profile of ofatumumab given outside clinical trials in patients with previously treated CLL. The secondary endpoints were efficacy, progression-free-survival (PFS), and overall survival (OS). Methods This was an observational, retrospective study. Patients were eligible regardless of prior treatments or disease status and provided they had not been included in ofatumumab clinical trials. Data on patients’ characteristics at diagnosis, prior treatment, adverse events response rate, PFS and OS were recorded. Results One-hundred and twenty patients were screened of which 103 from 25 centers in 10 European countries were eventually eligible for the study. There were 71 males; median age at initiation of ofatumumab was 64 years (range, 38-84); 66% patients were in advanced clinical stage (Rai III-IV/Binet C) and 33 patients presented bulky lymphadenopathy. Number of prior lines of therapy was 4 (range, 1-13). 94% had received prior F-based therapy, 54% received A-based therapy and 51% received both. Eighty-one percent had been previously exposed to rituximab-combination regimens. Fifty-four percent were F-ref, 70% A-ref and 41% were both F- and A-refractory. Cytogenetics within 3 months prior therapy was available in 52 patients of which 34 presented abnormalities (11 patients: 17p-; 9 patients: 11q-; 2 patients: 13q-; 1 patient: trisomy 12; 11 patients: two or more abnormalities including 17p- or 11q-). Forty-two of 50 patients showed unmutated IGHV genes. The median number of cycles of ofatumumab given was 9 (range, 0-16) and the median percentage of given/planned cycles was 83.3% (range, 0-133). In most patients the treatment dose and schedule were as follows: 300 mg 1st infusion followed by 2000 mg for subsequent infusions (8 weekly followed by 4 doses monthly). One hundred and sixty-one adverse events were reported in 68 patients, with 28 (17%) of them being considered as ofatumumab-related. Infusion related-reactions occurred in 19 (28%) patients (III-IV: 6%). Neutropenia was reported in 26% (III-IV: 19%), thrombocytopenia in 15% (III-IV: 12%) and anemia in 15% (III-IV: 7%). The non-hematological adverse events, included infection 44% (III-IV: 36%), fatigue 10% (III-IV: 4%), fever 10% (III-IV: 6%), rash 10% (III-IV: 3%), cough 7% (III-IV: 1%), diarrhea 6% (grade III-IV: 0%) and nausea 1% (III-IV: 0%). Hematologic toxicity correlated with the number of prior lines of therapy. Autoimmune hemolytic anemia and Richter syndrome were reported in one patient each. Two heavily pre-treated patients (5 and 6 prior lines of therapy, respectively) developed progressive multifocal leukoencephalopathy. The overall response rate (ORR) was 23% and the median PFS and OS were 5 and 12 months, respectively. The main causes of death were disease progression (61%) and infection (28%). Conclusions The safety profile of ofatumumab given outside clinical trials to patients with poor-prognosis and heavily pre-treated CLL was consistent with that observed in clinical trials. Although not unexpectedly the ORR was lower in this study, PFS and OS were in line with those reported in phase II trials.

Abstract Background: Ibrutinib (ibr), a first-in-class, once-daily Bruton's tyrosine kinase inhibitor, is approved by the US FDA for treatment of patients (pts) with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) including pts with del17p. The phase 1b/2 PCYC-1102 trial showed single-agent efficacy and tolerability in treatment-naïve (TN; O'Brien, Lancet Oncol 2014) and relapsed/refractory (R/R) CLL/SLL (Byrd, N Engl J Med 2013). We report efficacy and safety results of the longest follow-up to date for ibr-treated pts. Methods: Pts received 420 or 840 mg ibr QD until disease progression (PD) or unacceptable toxicity. Overall response rate (ORR) including partial response (PR) with lymphocytosis (PR-L) was assessed using updated iwCLL criteria. Responses were assessed by risk groups: unmutated IGVH, complex karyotype (CK; ≥3 unrelated chromosomal abnormalities by stimulated cytogenetics assessed by a reference lab), and in hierarchical order for del17p, then del11q. In the long-term extension study PCYC-1103, grade ≥3 adverse events (AEs), serious AEs, and AEs requiring dose reduction or discontinuation were collected. Results: Median age of the 132 pts with CLL/SLL (31 TN, 101 R/R) was 68 y (range, 37-84) with 43% ≥70 y. Baseline CK was observed in 41/112 (37%) of pts. Among R/R pts, 34 (34%) had del17p, 35 (35%) del11q, and 79 (78%) unmutated IGVH. R/R pts had a median of 4 prior therapies (range, 1-12). Median time on study was 46 m (range, 0-67) for all-treated pts, 60 m (range, 0-67.4) for TN pts, and 39 m (range, 0-67) for R/R pts. The ORR (per investigator) was 86% (complete response [CR], 14%) for all-treated pts (TN: 84% [CR, 29%], R/R: 86% [CR, 10%]). Median progression-free survival (PFS) was not reached (NR) for TN and 52 m for R/R pts with 60 m estimated PFS rates of 92% and 43%, respectively (Figure 1). In R/R pts, median PFS was 55 m (95% confidence intervals [CI], 31-not estimable [NE]) for pts with del11q, 26 m (95% CI,18-37) for pts with del17p, and NR (95% CI, 40-NE) for pts without del17p, del11q, trisomy 12, or del13q. Median PFS was 33 m (95% CI, 22-NE) and NR for pts with and without CK, and 43 m (95% CI, 32-NE) and 63 m (95% CI, 7-NE) for pts with unmutated and mutated IGVH, respectively(Figure 2). Among R/R pts, median PFS was 63 m (95% CI, 37-NE) for pts with 1-2 prior regimens (n=27, 3 pts with 1 prior therapy) and 59 m (95% CI, 22-NE) and 39 m (95% CI, 26-NE) for pts with 3 and ≥4 prior regimens, respectively. Median duration of response was NR for TN pts and 45 m for R/R pts. Pts estimated to be alive at 60 m were: TN, 92%; all R/R, 57%; R/R del17p, 32%; R/R del 11q, 61%; R/R unmutated IGVH, 55%. Among all treated pts, onset of grade ≥3 treatment-emergent AEs was highest in the first year and decreased during subsequent years. With about 5 years of follow-up, the most frequent grade ≥3 AEs were hypertension (26%), pneumonia (22%), neutropenia (17%), and atrial fibrillation (9%). Study treatment was discontinued due to AEs in 27 pts (20%) and disease progression in 34 pts (26%). Of all treated pts, 38% remain on ibr treatment on study including 65% of TN pts and 30% of R/R pts. Conclusions: Single-agent ibrutinib continues to show durable responses in pts with TN or R/R CLL/SLL including those with del17p, del11q, or unmutated IGVH. With extended treatment, CRs were observed in 29% of TN and 10% of R/R pts, having evolved over time. Ibrutinib provided better PFS outcomes if administered earlier in therapy than in the third-line or beyond. Those without CK experienced more favorable PFS and OS than those with CK. Ibrutinib was well tolerated with the onset of AEs decreasing over time, allowing for extended dosing for 65% of TN and 30% of R/R pts who continue treatment.

Abstract Introduction: Ibrutinib (Ibr) is a kinase inhibitor (KI) indicated for treating CLL. Clinical trials that led to its approval showed that its unique side effects differ from traditional chemotherapy toxicities. We previously reported (Mato et al, ASH 2015) that intolerance was the most common reason for discontinuation of Ibr in 123 patients treated in a real world setting. Whether reasons for discontinuation reported in clinical trials mirror those encountered in the real world is unknown and has not been studied. Therefore, we conducted a retrospective analysis of 621 CLL patients treated with Ibr either on clinical studies or commercially. We aimed to compare the type and frequency of toxicities reported in either setting, assess discontinuation rates, and evaluate outcomes. Patients and Methods: This multicenter, retrospective analysis included Ibr-treated CLL patients at 9 US cancer centers or the Connect® CLL Registry. We examined demographics, dosing, discontinuation rates and reasons, toxicities, and outcomes. The primary endpoint was progression-free survival (PFS) (time from KI treatment to progression, death or last f/u) as determined by the Kaplan Meier method. Comparisons of outcomes data were made using the log rank (LR) test. All other comparisons were descriptive. Results: 621 patients treated with Ibr were identified. Table 1 includes available baseline characteristics stratified by line of therapy. A total of 546 (88%) patients were treated with commercial drug. Clinical trial patients were younger (median age 57 vs. 61 years), had a longer time from diagnosis to Ibr (median 85 vs. 72 months) and were more consistently initiated at 420 mg daily (100% vs. 89%). With a median f/u of 14.5 months, the Ibr discontinuation rate was estimated to be 42% (median time to Ibr discontinuation was 7 months). Reasons for discontinuation are listed in table 2. Notably, Ibr toxicity was the most common reason for discontinuation in all settings. Ibr starting dose (420 mg daily vs. < 420 mg daily) did not impact the proportion of patients who discontinued Ibr due to toxicity (51% vs. 50%). In relapsed CLL, the 5 most common Ibr-related toxicities as a reason for discontinuation included: atrial fibrillation (12.3%), infection (10.7%), pneumonitis (9.9%), bleeding (9%), and diarrhea (6.6%). In front line CLL, the 3 most common Ibr-related toxicities as a reason for discontinuation included arthralgia (41.6%), atrial fibrillation (25%), and rash (16.7%). Median times to discontinuation by toxicity were as follows: bleeding (8 months), diarrhea (7.5 months), atrial fibrillation (7 months), infection (6 months), arthralgia (5 months), pneumonitis (4.5 months), and rash (3.5 months). Median PFS and OS for the entire cohort were 35 months and not reached (median f/u 17 months) respectively. Figure 1 describes PFS for Ibr treated patients stratified by line of therapy (A), reason for discontinuation (B), clinical trial participation (C) and depth of response (D). In a multivariable model, complex karyotype was validated as an independent predictor of PFS (HR 1.6, CI 1.1-2.5 p=.04) but not OS (HR 1.6, CI .9-3.1 p=.1). Conclusions: In the largest reported series on Ibr-treated CLL patients, we show that 40% of patients have discontinued Ibr during this observation period. Intolerance as opposed to CLL progression or transformation was the most common reason for discontinuation. As compared to previous reports from clinical trials, the discontinuation rate appears to be higher suggesting (1) a learning curve in terms of toxicity management, (2) a higher incidence of toxicity in clinical practice, (3) or a lower threshold for discontinuation given alternative choices. Outcomes remain excellent and were not impacted by line of therapy and whether patients were treated on studies or commercially. These data strongly argue to find strategies to minimize Ibr intolerance so that efficacy can be further maximized. Figure 1 Figure 1.

Abstract Background: Multiple myeloma (MM) risk stratification schemata such as the International Staging System (ISS) and Revised-ISS (R-ISS) were derived from clinical trial subjects made up predominately of younger White individuals with adequate renal function. It is unknown whether these prognostic indices are applicable to all patients with newly diagnosed (ND) MM, especially among Black individuals, older adults, and those with renal dysfunction. The R-ISS expanded on the ISS by including and serum lactate dehydrogenase (LDH) and high-risk cytogenetic abnormalities (HRCA) identified by fluorescence in-situ hybridization (FISH), but HRCA may not translate into poor prognosis for older adults and for Black individuals. We sought to create an inclusive risk prognostic index for NDMM using real-world data derived from electronic health records. Methods: De-identified NDMM patient-level data in the real-world setting was provided by COTA, Inc. 3000 patients were identified who met the inclusion criteria of NDMM between 2005 and 2020. Baseline diagnostic parameters available within 60 days before or after diagnosis were included. Progression free survival (PFS) was defined as the time from diagnosis to disease progression or death of any cause. Overall survival (OS) was defined as the time from diagnosis to death of any cause. Proportional hazards models were used to calculate hazard ratios (HR) and 95% confidence intervals for all-cause mortality. Age-adjusted univariate analyses identified variables significantly associated with OS, and continuous variables were dichotomized based on accepted cutoffs. Multivariate Cox models to identify the variables with the strongest association with OS were performed adjusting for age, sex, Black race, receipt of proteasome inhibitor and immunomodulatory imide during induction, autologous stem cell transplant within 1 year of diagnosis, ECOG performance status, and creatinine. An additive risk score was created with one point given to each significant variable. The risk score was then validated for PFS using the Multiple Myeloma Research Foundation's (MMRF) CoMMpass database (version IA15). Results: 3000 NDMM pts from the COTA, Inc. real-world database were initially evaluated, and a total of 689 NDMM pts had sufficient level of data to be included. The median follow-up time was 49.9 months (interquartile range (IQR) 29.1-76.2 months). Median age was 64 (IQR 32-86), including 44% age 65+. Of the 607 with reported race, 474 (78%) were White, 86 (14%) Black, 17 (3%) Asian, and 30 (5%) other. Of the 676 pts with reported serum creatinine (mg/dL), the median was 1 mg/dL (IQR 0.8-1.3) with 85 (13%) measuring >2 mg/dL. Examined peripheral blood variables were: calcium (corrected for albumin), albumin<3.5 mg/dL, beta2-microgloublin (B2M) >3.5 mcg/mL, LDH >250 U/L, hemoglobin <10 g/dL, M-spike >3 g/dL, and IgA isotype. Variables with significance using multivariate analysis at p<0.1 were: LDH>250 U/L, B2M >3.5 mcg/mL, hemoglobin <10 g/dL, and IgA isotype. These variables were simultaneously present in 558 patients. Patients were stratified into 3 groups: standard (std score = 0, n=186), intermediate (int score = 1-2, n=295), and high (score 3-4, n=77) risk. For this inclusive risk prognostic index (IRPI), the c-statistic was 0.61 for OS (HR 2.0, 95% CI 1.5-2.6, p<0.001) which compared favorably to the c-statistic for ISS (c=0.64, HR 1.8, 95% CI 1.5-2.2, p<0.001) and for R-ISS (c=0.63, HR 2.0, 95% CI 1.6-2.6). For the IRPI, median OS was 218 (std) vs 121.5 (int) vs 79.5 months (high). In comparison, median OS by ISS was 198.9 (stage I) vs 121.6 (stage II) vs 80.6 months (stage III), and by R-ISS: 198.9 (I) vs 121.6 (II) vs 79.5 months (III). Validation of the inclusive risk prognostic index (IRPI) using the MMRF CoMMpass database in 938 patients with all four criteria showed median PFS was 44 (std) vs 33 (int) vs 20.5 months (high). In comparison, median PFS by ISS was 45.9 (I) vs 31.5 (II) vs 20.5 (III) months. Median PFS by R-ISS was 50.1 (I) vs 32.7 (II) vs 19.1 (III) months. Conclusions: Employing real-world datasets that incorporate a more diverse patient population led to the generation of an inclusive risk prognostic index incorporating beta2-microgloublin, LDH, hemoglobin, and IgA isotype. This IRPI does not require bone marrow sampling, performs similarly to ISS and R-ISS in predicting PFS, and with datasets with longer follow-up may prove to predict OS. Figure 1 Figure 1.

Abstract Introduction: The use of B-cell receptor (BCR) signal inhibitors-based therapies (e.g., Ibrutinib) for B-chronic lymphocytic leukemia (CLL) was initiated just a few years ago but has rapidly escalated due to their clinical efficacy and relative ease of use. However newer therapeutic approaches are needed due to multiple issues including the continued need to improve complete responses and reduce toxicity profiles. To that end our group has discovered a novel membrane target in the ubiquitous presence of Axl receptor tyrosine kinase (Axl RTK) on CLL B-cells and has reported that the Axl RTK inhibitor TP-0903 is able to induce apoptosis of CLL B-cells at nanomolar doses (Sinha, Clin Cancer Res, 2015). Given this we assessed if TP-0903 would be effective in the induction of apoptosis of leukemic B-cells from CLL patients who are currently on Ibrutinib therapy or whom have relapsed while on Ibrutinib treatment. Methods: Relapsed/refractory CLL patients (n=22) who were placed on Ibrutinib for progressive disease provided blood samples at a median of 3.2 months after Ibrutinib therapy initiation for these studies. We also obtained sequential samples on 8 patients from initial start of ibrutinib therapy and then over a 6 month follow-up period. CLL B-cells from these blood samples were subject to Ficoll separation, purified by using a Rosette Sep B-cell enrichment kit and then studied by flow cytometry to determine Axl RTK expression levels by flow cytometric analysis. Purified CLL B-cells (CD19+/CD5+) were cultured with TP-0903 in vitroat increasing doses (0.01µM - 0.50µM) for 24 hours and the LD50 dose was determined. In addition, 3 CLL patients who had been on Ibrutinib therapy and had a documented relapse were studied in similar fashion using TP-0903. LD50-sensitivity was measured. "LD50-sensitivity" was defined as an LD50 ≤0.50µM and "insensitive" was defined as an LD50 dose >0.50µM. CLL prognostic factors (e.g., FISH, IGHV mutation status, Rai stage, CD38, and CD49d) were evaluated at the time of ibrutinib treatment. Differences in factors between sensitive and insensitive cases were computed using the Kruskal-Wallis test for continuous variables and Chi-square test for categorical variables. Results: Twenty-two CLL patients (5 female, 17 male) were included in the analysis. Fourteen (64%) patients were found to be TP-0903 LD50-sensitive. Axl expression on CLL B-cells for this cohort was heterogeneous with a median of CD19+/CD5+ cells positive for Axl at 69.9% (range of 2.7-91.3%). The sensitive subjects tended to be younger with a median age at Ibrutinib treatment initiation of 62 vs 75.5 years (p=0.004). There were no significant differences in gender, FISH, IGHV mutation status, CD38, CD49d, or Rai stage between the sensitive and insensitive LD50 groups. There were no significant differences in relation to median Axl expression on CLL B-cells (sensitive: 72.6%, range: 2.7-91.3%; insensitive: 41.5%, range: 16.5-83.1%; p=0.35). The median number of treatments prior to initiation of ibrutinib did not differ between sensitivity groups (sensitive: 2.53, range: 8-10; insensitive: 43.5, range 12-20; p=0.2833). Association for ZAP70+ CLL B-cells tended to have more apoptosis induction by TP-0903 (sensitive: 84.6% ZAP70+; insensitive: 42.9% ZAP70+; p=0.052). In 8 CLL patients that were studied sequentially while on Ibrutinib continued to express Axl or increased their Axl expression (n=2) over a 3-6 month follow-up period. Three CLL patients who had relapsed on Ibrutinib were sensitive to TP-0903 with LD50 values of ≤0.50µM. Summary: Here we find that CLL B-cells from over 60% of relapsed CLL patients on Ibrutinib therapy were highly sensitive to the high-affinity Axl inhibitor TP-0903 with induction of apoptosis at nanomolar doses (≤0.50µM). The sensitivity of CLL B-cells to TP-0903 appears to be independent of Axl expression levels and of the known CLL prognostic factors but more evident for younger patients and for ZAP70+ expression status. Given this level of activity for apoptosis induction of CLL B-cells by TP-0903 encourages the further testing of this drug in clinical trials for CLL patients.

Abstract Introduction The thrombopoietin (TPO) mimetic agents romiplostim and eltrombopag are used to stimulate platelet production and increase platelet counts in chronic immune thrombocytopenia (ITP) in adults. While two large, randomized trials investigating dosing, safety, and efficacy were ongoing in children, but not near completion, we conducted a retrospective IRB-approved analysis of 33 pediatric (≤21 years) chronic ITP patients from two centers treated with TPO agents off-study. Patients Patients initiated TPO therapy prior to 21 years of age (19 months to 19 years, median 14 years) after an average of 3.6 ITP therapies; 21 patients received romiplostim [11 at Children's Hospital of Orange County (CHOC), 10 at Weill Cornell Medical Center (WCMC)] and 12 eltrombopag [all at WCMC]. Median starting age was 11.5 years for patients on romiplostim and 16.5 years on eltrombopag. Primary response measures were: platelet counts ≥ 50 x 109 per liter or ≥20 x 109 per liter above baseline for 2 consecutive weeks and 50% of platelet counts ≥ 50 x 109 per liter. Duration of treatment and bone marrows with myelofibrosis (MF) consensus grade are shown in Figure 1. Results 27/33 (82%) patients responded to TPO agents; 18/21 to romiplostim and 9/12 to eltrombopag. Ten patients responded to ROMIPLOSTIM as a single agent; 8 romiplostim responders received concurrent medications including: mycophenolate mofetil (MMF), azathioprine (AZA), rituximab, and cyclosporine (CSA). One of two splenectomized patients was able to wean off TPO therapy with adequate counts. Two additional patients successfully discontinued TPO therapy and continued on MMF alone. Two patients (1 CSA, 1 AZA) successfully discontinued TPO therapy and then weaned off concurrent therapy. Eighteen of 21 patients had platelet counts ≥ 50 x 109 per liter or ≥20 x 109 per liter above baseline for 2 consecutive weeks and 18 had 50% of platelet counts ≥ 50 x 109 per liter (table). In this study, duration of successful romiplostim use outside of randomized clinical trials ranged from 6-44 months (11/18 ongoing). 3 patients did not respond and 2/3 went on to have therapeutic splenectomies. 1 patient with Evans syndrome had a transient 1 year response before relapsing. 5 responders to romiplostim had previously received eltrombopag with lesser or no effect. Nine of 12 patients responded to ELTROMBOPAG with platelet counts ≥ 50 x 109 per liter or ≥20 x 109 per liter above baseline for 2 consecutive weeks and 8/12 had 50% of platelet counts ≥ 50 x 109 per liter. One patient had been splenectomized; 7 responded to eltrombopag alone. 2 patients had concurrent therapy with prednisone and IV Anti-D and 1/2 was able to discontinue concurrent prednisone. One patient successfully discontinued eltrombopag with adequate counts for > 1 year. 5 patients attempted unsuccessfully to discontinue therapy. One responder, a previous romiplostim responder, switched to eltrombopag. No other patients were treated with TPO agents prior to starting eltrombopag. Duration of successful eltrombopag use outside of randomized clinical trials ranged from 23-53 months (7/12 are ongoing). Three patients did not respond to eltrombopag; 1/3 was HIV positive. One patient experienced a provoked DVT at site of ankle fracture while using eltrombopag. No other patients on either therapy experienced serious drug-related adverse events. Among 24 bone marrows (both agents; 21 reflecting off study use), only MF grades 0 -1 were seen. 10/24 marrows were performed after greater than 2 years of therapy. Conclusion Retrospective analysis of off-study use of eltrombopag and romiplostim in children shows that these TPO agents effectively increase platelet counts in more than 3/4 of children with chronic ITP, a result consistent with adult TPO use. Despite small sample size, the long-term duration of successful use (6-53 months) without tachyphylaxis supports efficacy. Re safety, the one DVT appeared to be precipitated by a fracture and there were no MF2/3 bone marrows in the 24 samples. In those patients who do not respond to one TPO agent, it may be beneficial to switch to the other form. Disclosures: Nugent: Bayer: Honoraria; CSL Behring: Honoraria; Novo Nordisk: Honoraria.
