Efficacy of a conversion from filgrastim to filgrastim-sndz in stem cell transplant patients undergoing mobilization

During autologous stem cell transplant, granulocyte colony-stimulating factors (G-CSF) serve the integral role of mobilizing hematopoietic cells into the peripheral blood for subsequent collection by leukapheresis. Filgrastim (Neupogen®) is a G-CSF and affects hematopoietic cells by stimulating growth and differentiation of neutrophils. Filgrastim-sndz (Zarxio®), a biosimilar of filgrastim, received landmark approval as the first biosimilar product approved by the FDA in the United States. As a result of the recent FDA approval, our medical center made the conversion in August 2016 from using filgrastim to filgrastim-sndz to provide patients the same benefits of the filgrastim injection at a reduced cost. This retrospective, observational cohort study evaluated the comparative efficacy of the filgrastim-sndz biosimilar in 147 patients who underwent mobilization prior to stem cell transplant with filgrastim between 1 August 2015 and 31 July 2016 or filgrastim-sndz between 1 September 2016 and 30 November 2017. The mean number of CD34 cells collected during apheresis was 7.38 × 106 in the filgrastim group and 8.86 × 106 in the filgrastim-sndz group. Filgrastim-sndz was significantly non-inferior, as the difference between filgrastim and filgrastim-sndz was −1.48 × 106 with an upper 95% confidence bound equal to −0.24 × 106 that did not include the non-inferiority margin of 1 × 106 ( p = 0.0006). The median number of days of apheresis was 2 in both groups ( p= 0.3273). In conclusion, the biosimilar product was non-inferior for mobilization and the conversion from filgrastim to filgrastim-sndz afforded patients similar efficacy for mobilization in stem cell transplant at a reduced cost.

Abstract Abstract 3469 Introduction: Stem cell transplantation is important in the management of multiple myeloma. In the United States, the standard of care is administration of growth factors to accelerate neutrophil recovery after stem cell transplant. The need for growth factors after transplant has not been investigated recently. Patients: We analyzed a cohort of 166 patients at our institution who underwent autologous transplant for multiple myeloma without receiving growth factors after transplant and compared them with 498 patients who received standard filgrastim beginning on posttransplant day 5. TABLE Results: A neutrophil count of 500/μL was achieved in a median of 12.5 days in patients receiving growth factor, compared with 13.5 days in those not receiving growth factor (P<.001) Fig 1. Platelet engraftment was identical (median, 14.5 days; P=.12) in both groups, despite a lower median number of CD34+ cells infused in patients who did not receive growth factors. Incidence of nonstaphylococcal bacteremia was identical in both groups. The median hospital stay was 3.5 days shorter in the group not receiving growth factor. Bacteremia impacted platelet but not neutrophil engraftment. Figure 2 Conclusion: It is feasible and reasonable to perform autologous stem cell transplant for multiple myeloma without administering growth factors. Estimated savings would be $4,600 for each transplanted patient. Growth factor administration is not required for a safe outcome and decreases the number and severity of some of the fluid-related complications after transplant such as acute respiratory distress syndrome, allergic reactions, alveolar hemorrhage, and rarely splenic rupture.

Abstract Alkylating agents remain among the most potent therapies available for treatment of Multiple Myeloma (MM). Their use prior to, or following, autologous stem cell transplant (ASCT) is, however, compromised by concerns about stem cell quality and by myelosuppression limiting effective dose delivered. To address this concern we have studied a combination of cyclophosphamide 500 mg p.o. once weekly and prednisone 100 mg p.o. on alternate days in 66 patients requiring salvage therapy post-ASCT. Dose reductions were allowed for toxicity beginning at cycle 2. On an intent to treat basis, 66 patients received this regimen, however, 7 of these patients were not fully evaluable for response due to non-secretory disease. Of the 59 patients evaluable for response, the median time from transplant to treatment was 26.4 months (range, 6.0 to 66.6). The median time from post-transplant relapse to start of cyclophosphamide and prednisone (C/P) therapy was 1.4 months. The median number of therapies from time of diagnosis to C/P initiation was 2 (range, 1.0 to 5.0). At the date of analysis, treatment with C/P is ongoing in 12 (20.3%) patients, with a median duration of 3.6 months (range, 1.9 to 11.6). The 47 patients who have completed C/P therapy were treated for a median time of 5.5 months (range, 0.5 to 21.7). The reason for discontinuation among these 47 patients included disease progression (42.6% of patients discontinued), plateau disease (21.3%), receiving a second transplant (17.0%), toxicity (10.6%), or switched to another regimen (8.5%). A partial response (>50% protein reduction) was obtained in 37.3% of patients, 18.6% attained minimal response (25–50% protein reduction), 33.8% patients stable disease, while 10.2% patients had progressed on treatment. The estimated median (95% CI) months of progression-free survival after start of C/P treatment is 14.9 (8.7, 21.7). Twenty-three (38.9%) of patients have relapsed after C/P treatment, a median (range) of 8.7 (0.5–65.7) months after start of C/P treatment. At 6 months 74.3% (95% C.I. 61.9% – 89.1%) of patients were progression-free with 28% (95% CI: 16.1–49.2%) progression free at two years. At time of analysis, 44 (74.6%) patients are still alive, with a median follow up of 10.6 months (range, 1.2 to 65.7) since the start of C/P therapy. Fifteen patients have died at a median 13.0 months (range, 1.4 to 61.7) since the time of C/P initiation. The median overall survival (95% C.I.) is estimated to be 35.9 months (24.2, NA). These results demonstrate that the combination of oral cyclophosphamide and prednisone is an effective (56% MR or PR), very well tolerated (10% discontinued due to toxicity) and convenient treatment as salvage MM therapy post-ASCT. The relative lack of myelosuppression allows for re-collection of stem cells and salvage transplant while retaining other active second line agents for later relapse. This regimen thus compares favorably with recent salvage therapeutics introduced in MM and is now being studied in combination with these newer active agents and in induction therapy.

Abstract Abstract 2731 Background: Survivin is responsible for preservation of cell viability and regulation of mitosis in tumor cells. Survivin is overexpressed in the majority of aggressive B-cell lymphomas and thus is an attractive target in subjects with relapsed lymphoma. YM155 is a survivin suppressant that in vitro, when combined with rituximab, synergistically enhances the induction of apoptosis in lymphoma cells. In human DLBCL xenograft models, this combination significantly inhibits tumor growth and prolongs survival. Based on these preclinical combination data and single agent clinical data, a Phase 2 study utilizing YM155 rituximab was initiated. Methods: The study employs a two-stage group sequential method, designed to enroll a total of 40 subjects with an interim futility assessment (Stage I). Eligible patients have histologically confirmed relapsed CD20-positive primary or transformed diffuse large B cell lymphoma (DLBCL) or grade 3 follicular lymphoma (FL) and are either not candidates or previously had an autologous stem cell transplant (ASCT). Subjects had received ≥ 1 prior anthracycline containing regimen with a documented response to the last regimen prior to study entry. Induction, ASCT and maintenance therapy were considered as one regimen. The dosing regimen was YM155 5 mg/m2/day as a 168 hour (7-day) continuous infusion in a 14 day cycle and rituximab 375 mg/m22 Days 1 and 8 cycles 1 – 4 and then repeated every 10 cycles. The primary endpoint of the study is objective response rate (ORR) per modified IWG 2007. Imaging studies are performed every 8 weeks (4 cycles) after initiation of therapy. In order to continue enrolling in the study, an overall response rate of 4/16 (25%) must be achieved. Results from the completed Stage I are reported here. Results: Sixteen subjects, the majority of whom were male 13/16 (81%), were enrolled in Stage I. The median age was 62.9 (range: 32 – 78) with a majority of subjects 15/16 (93.8%) with DLBCL. IPI/FLIPI scores were intermediate in 10 subjects (62.5%) and high in 3 subjects (18.8%). The median number of prior therapies was 2 (range: 1 – 5), 16/16 (100%) of patients received rituximab in 1st or subsequent lines of therapy. Seven patients (43.7%) had prior ASCT. The median number of cycles of YM155 administered was 11 (1–37). The overall response rate was 9/16 (56.3%) with 2/16 (12.5%) CR, 7/16 (43.8%) PR and 4/16 (25%) SD. The median time to response was 53 days (range: 52 – 109). Median duration of response and median PFS has not been achieved. Clinical benefit rate was 13/16 (81.3%). The most common adverse events reported, regardless of relationship, were pyrexia 8/16 (50%), cough 7/16 (43.8%), asthenia 5/16 (31%) and fatigue, back pain, vomiting, neutropenia and thrombocytopenia each 4/16 (25%). Five subjects (31.3%) experience Grade 4 adverse events and 2 (12.5%) had Grade 5 adverse events (disease progression and respiratory failure), neither of which was considered related to therapy. The most common Grade 4 event was neutropenia 4/16 (25%), with all other Grade 4 events occurring in only 1 subject (febrile neutropenia, thrombocytopenia, general physical health deterioration, infusion site extravasation, central line infection, infective thrombosis, mediastinitis, dyspnoea, pleural effusion). Conclusion: In subjects with relapsed aggressive NHL receiving combination YM155 and rituximab, the ORR for Stage I was 56.3%, which exceeds the requirement to continue to Stage II. Overall the combination regimen was well tolerated with limited hematologic toxicities. Stage II enrollment is ongoing. Disclosures: Papadopoulos: Astellas: Consultancy, Research Funding.

Abstract INTRODUCTION: Autologous stem cell transplant (ASCT) is a potentially curative option for lymphoma, yet there remains a bias against offering this therapy to the elderly. Patients above age 65 are nearly always excluded from clinical trials with ASCT, limiting our understanding of the efficacy and toxicities of ASCT in this population. This lack of data and bias against ASCT in the elderly may delay referral for patients who may benefit from a transplant. Here, we report our single institution outcomes from all patients aged 65 and greater who underwent autologous stem cell transplant for lymphoma at our institution. DESIGN AND METHODS : We identified 93 consecutive patients ³ 65 years of age (median age 68.6 years) with lymphoma who underwent autologous stem cell transplantation at University of Kansas Medical Center from 2000 to 2015. After IRB approval, data was extracted using the institutional database. These patients had frequently received at least two treatments, were often beyond first complete remission at the time of transplantation and received their transplants later after diagnosis. Table 1 below summarizes the pre-transplant characteristics of our patients. RESULTS: All patients received G-CSF mobilized peripheral blood stem cells. Engraftment data is available for 87 out of 93 patients. Median number of days to neutrophil recovery (Absolute neutrophil count >500) was 11 (range 9-14). Median number of RBC and platelet transfusion in this group was 2 (range 0-10) and 3 (range 0-39), respectively. Non-relapse mortality at 100 days for the entire group was 2.15%. Overall survival at 100-days was 96.8%. Three patients (3.2 %) developed grade IV pulmonary toxicity and one patient developed grade IV veno-occlusive disease. With a median follow up of 744 days (41-2431), a disease free survival of 373 days was noted. In 63 patients who underwent transplant prior to 2013, 1-year and 2-year overall survival was found to be 84.2% and 72.1 respectively. Of the deaths in first year, 6 (55%) were related to relapse/progression, two (18%) due to pulmonary toxicity, 2 (18%) due to cardiac toxicity and 1 (9%) due to infection. In 17 patients (18.2%), transplant was performed completely/partially as an outpatient procedure. CONCLUSIONS: Although retrospective in nature, these results suggest that transplant related mortality in elderly patients with lymphoma is similar to historic younger cohorts. Chronological age should not be used alone in evaluating lymphoma patients for autologous stem cell transplantation. Instead, a comprehensive evaluation using Hematopoietic cell transplant comorbidity index and geriatric assessment should be used to guide decision-making. As the elderly population grows, an individualized approach to each patient considering all available treatment options is needed to make a potentially curative ASCT for high risk or relapsed lymphoma available to more patients.

Abstract Abstract 4391 Background: High dose chemotherapy followed by autologous transplantation of peripheral blood stem cells plays an important role in the management of intermediate- and advanced-stage multiple myeloma. In order for successful engraftment to occur, adequate numbers of high quality peripheral stem cells must be harvested prior to transplantation. Mobilization of PBSC in patients treated with lenalidomide has been associated with poor apheresis collections after G-CSF mobilization. The purpose of this study is to present our institution’s experience utilizing an intermediate-dose cyclophosphamide-based mobilization regimen. Methods: We retrospectively analyzed data for patients with multiple myeloma who underwent autologous stem cell transplant at UCLA between 2006 and 2010. Data were obtained from the database of the UCLA Heme Malignancy/Stem Cell Transplant Unit, the electronic health record system and stem cell processing laboratory. All patients underwent mobilization with a regimen of cyclophosphamide 2.5g/m2 IVPB, G-CSF 10 mcg/kg/day for 4 days SQ, and prednisone 2mg/kg/day for 4 days po. The number of CD 34+ cells was used as a marker for the number of peripheral stem cells collected. Minimum dose collected to ensure adequate engraftment was 2×106/kg CD34+ cells. Patients were conditioned with melphalan 100mg/m2/d x2 (unless there was evidence of renal failure, in which case the dose was reduced to 100mg/m2) with subsequent infusion of stem cells. Neutrophil engraftment was defined as the first day of absolute neutrophil count greater than 500×106/L ≥ 7 days after transplant. Results: Autologous stem cell transplant was performed in 103 patients with multiple myeloma at UCLA between 2006 and 2010. Median number of apheresis procedures was 1 (1–12) with a median of 4.4×106/kg (1.4–33.5) CD34+ cells collected. Median time to engraftment was 10 (8–18) days. Thirty-five patients received lenalidomide at some point in their pretransplant treatment. Median number of apheresis procedures was 1 in both lenalidomide and non lenalidomide treated groups. In the lenalidomide treated group 54% required only one collection versus 75% in the non lenalidomide treated group (p=0.033). In the lenalidomide treated group 31% required 3 more or more collections versus 10% in non lenalidomide treated group (p=0.0075). Three patients in the lenalidomide group had subsequent mobilization with plerixafor with one of these requiring bone marrow harvesting. Median CD34+ cells collected was 3.5×106/kg and 4.9×106/kg (p=0.246) in the lenalidomide and non-lenalidomide groups respectively. Both groups had a median time to neutrophil engraftment of 10 days with a similar range. Conclusion: Pre-transplant use of lenalidomide adversely affected the number of stem cell apheresis procedures required to procure adequate stem cell dose as evidenced by a greater percentage requiring 3 or more collections. However, despite prior lenalidomide exposure, the use of our mobilization regimen permitted adequate collection, with the majority of patients requiring only one apheresis procedure, and led to an equivalent time to neutrophil recovery. Disclosures: Off Label Use: Cyclophosphamide and G-CSF for mobilization of stem cells.

6549 Background: Autologous stem cell transplant (ASCT) remains part of standard therapy for Multiple Myeloma (MM). Lenalidomide (LEN) is a newer, effective therapy for MM. It has been suggested that prior LEN therapy is associated with an increased risk of stem cell collection failure, particularly when only G-CSF is used for mobilization. Methods: We conducted a retrospective chart review of 310 consecutive MM pts who underwent pheresis to collect stem cells for first ASCT between July 1, 2007 and June 30, 2011 at the Karmanos Cancer Institute. We compared differences in quantity of CD34 cells collected, days needed to collect the target number of cells (> 2.5 x 10*6 CD34+ cells/kg), days to platelet and neutrophil engraftment. We also evaluated the association between CD34+ cells collected and the number of cycles of LEN therapy. Results: Of 310 patients, 90% were mobilized with only G-CSF initially. Patients were analyzed as two groups: LEN exposed (LEN(+); n = 128) and LEN naive(LEN(-); n = 182). Median age in both groups was 58 years. No differences in race, sex and MM stage distribution were observed between the two groups. The median number of stem cells collected in the LEN(+) group was significantly less than the LEN(-) group (6.46 vs. 7.56 x 10*6 CD34 cells/kg; p= 0.0004). In addition, the median number of pheresis sessions required for adequate stem cell collection were significantly more in the LEN(+)group as compared to LEN(-) group (2 vs.1 sessions; p=0.002). In the LEN(+) group, there was a negative correlation between CD34+ cells collected and the prior number of cycles of LEN (p=0.0001). There was no statistically significant excess in the number of stem cell collection failures with G-CSF in the LEN(+) group (7% vs. 4% p=0.31). All pts who failed collection after G-CSF were successfully collected with Cytoxan or Plerixafor priming. LEN exposure had no effect on post-ASCT neutrophil or platelet recovery. Conclusions: Although Lenalidomide exposure is associated with a slightly lower CD34+ stem cell yield and on average an extra session of pheresis when G-CSF is used for mobilization, collection failure is uncommon and post-ASCT engraftment is normal.
