Abstract Abstract 131 Introduction. Autologous stem cell transplantation (ASCT) after cytoreductive induction is considered standard of care for younger patients (pts) with multiple myeloma (MM). The previous standard of induction, the Vincristin-Adriamycin-Dexamethasone (VAD) combination, achieves inferior results compared with induction regimens which combine the proteasome inhibitor Velcade (V = Bortezomib) with Dexamethasone (D)(=VD) and a cytostatic drug such as Doxorubicin (PAD = VD plus Doxorubicin). Velcade-based induction therapy was shown to translate into better myeloma control after high dose melphalan and to lead to prolonged progression-free survival. In order to find a more efficacious and safer drug combination for induction therapy in MM, we tested the combination of Velcade with Cyclophosphamide and Dexamethasone (VCD). Methods. This trial was designed as an open, prospective, multi-center, uncontrolled, combined phase II/III study. As previously reported (Kropff M et al., Ann Hematol 2009), in the first 30 pts the optimal dose of iv Cyclophosphamide in combination with V and D was defined as 900 mg/m2 on d1. Between 03/2006 and 03/2009 we enrolled an additional 370 pts up to 60 years of age with untreated MM to receive three 3-week cycles of induction treatment with V 1.3 mg/m2 iv d1,4,8,11; D 40 mg/d orally d1,2,4,5,8,9,11,12; and C 900mg/m2 iv d1 before scheduled high dose melphalan and ASCT. The primary endpoint of the study is response rate on day 63 after 3 cycles of VCD according to EBMT and IMWG criteria. Results. Final data from 400 pts from 39 German centers will be presented at the meeting. In the currently evaluable 300 pts (mean age 52.3 years; 1.7% stage I, 21.3% stage II, 77.0% stage III) molecular cytogenetic analysis showed a prevalence of 13q- in 38%, of t[4;14] in 13% and of 17p- in 12% of pts (no changes in 35%). All 300 pts (88.3% of whom completed three cycles) were included in the intent-to-treat analysis. Overall response rate (ORR = CR+PR) was 84%, with 10% CR and 74% PR, 5.7% MR, 7.3% NC and 2.3% PD. The negative prognostic impact of 13q- or t[4;14] was abrogated (ORR normal 87.3%, 13q- 83.7%, t[4;14] 90.0%), the unfavorable influence of p53 loss in the 17p- subgroup was still detectable (ORR 69.2%) but this did not reach statistical significance. VGPR rates will be reported at the meeting. Serious adverse events were documented in 78/300 (26.0%) patients. Death rate was remarkably low (1.3%, of which one was not related to the trial medication). 155/300 (52%) of pts experienced grade 3/4 non-serious AEs and of these leucopenia (93/300 pts= 31%), thrombocytopenia (7%), neutropenia (6%), anaemia (5%) were the most frequent events. 80 AEs grade 3 or 4 and 45 SAEs were of infectious origin and occurred in 47/300 pts. 80/130 SAEs (61.5%) were at least possibly related to Velcade. 101/300 pts (34%) developed episodes of peripheral neuropathy. PNP was grade 1 in 62/300 pt (20.7%), grade 2 in 31/300 pt (10.3%) and grade 3 in 7/300 pts (2.3%). Conclusion. This analysis demonstrates that proteasome inhibition by Velcade in combination with Dexamethasone and iv Cyclophosphamide (VCD) is an induction regimen for newly diagnosed MM which is highly effective in a short period of time, has a rather low toxicity profile and is feasible for administration in an outpatient setting. Based on these characteristics, VCD qualifies to become a new standard for MM induction therapy.

Abstract Background: Despite recent improvements, myeloma is still incurable. There is need to add new therapeutic tools. For young and fit patients, the current standard first-line therapy is a proteasome inhibitor (PI) containing induction, followed by stem cell collection, high dose Melphalan and autologous stem cell transplantation, followed by maintenance lenalidomide therapy in Canada. The anti-CD38 antibodies showed interesting activity in myeloma, and significant synergism with PI and IMiD based regimens. This CMRG-008 trial is designed to explore the benefit of adding Isatuximab to the current Canadian standard of care (CyBorD induction/Autologous SCT/Maintenance Len) in a single arm phase II trial. Design and Methods: Phase II study. Transplant eligible newly diagnosed myeloma patients (TE-NDMM) will receive Isatuximab added to four cycles of standard induction CyBorD chemotherapy (Cyclophosphamide 300 mg/m 2 PO, Bortezomib 1.5 mg/m 2 SC, and Dex 40 mg PO, all given on days 1, 8, 15 and 22 of 28-day cycles; Isatuximab 10 mg/kg IV days 1, 8, 15 and 22 of cycle 1; days 1 and 15 of cycles 2-4). After the completion of the induction treatment, subjects achieving at least stable disease will receive stem cell mobilization, collection of hematopoietic stem cells, high dose melphalan chemotherapy, and autologous stem cell transplantation. Maintenance treatment will start at 100 days (+/- 7 days) after the transplantation date (and to be continued until disease progression). The maintenance treatment will consist of Isatuximab administered in combination with Lenalidomide in 28-day cycles (Lenalidomide: 10 mg daily on days 1-21 of every cycle; Isatuximab: 10 mg/kg IV on days days 1, 8, 15 and 22 of cycle 1; days 1 & 15 of cycles 2-3; then day 1 of each subsequent cycle). The objectives: To evaluate the benefit of adding Isatuximab to CyBorD (induction = Isa + CyBorD) and Lenalidomide (maintenance = Isa + Lenalidomide) in transplant-eligible myeloma patients. Primary Endpoint: To determine the response rate (VGPR or better) defined by IMWG criteria at 100 days (+/- 7 days) after the autologous stem cell transplant (ASCT). Secondary Endpoints: A) To determine the response rate (VGPR or better) after induction treatment (before ASCT), and at 12 months, 24 months and 36 months. B) To evaluate additional efficacy outcomes including progression free survival (PFS), and overall survival (OS), time to response and duration of response. C) To confirm the feasibility, safety and tolerability of adding Isatuximab to CyBorD and to maintenance lenalidomide in transplant-eligible newly diagnosed myeloma patients. D) To determine the feasibility of autologous stem cell collection after Isa + CyBorD induction treatment. The key inclusion criteria are having a TE-NDMM with a measurable disease; adequate performance status; and adequate organ functions. The key exclusion criteria include previous exposure to anti-CD38 therapy, intolerance to CyBorD, adverse cardiac history, pulmonary disease, central nervous system disease, congenital or acquired immune suppression, and other concurrent severe or uncontrolled medical conditions. Statistics and Sample Size: Considering that the response rate (VGPR or better) after CyBorD induction therapy, high dose chemotherapy and autologous SCT is about 70-78%; and assuming a response rate (VGPR or better) to Isa-CyBorD induction and autologous stem cell transplant at 100 +/- 7 days of 88%; a sample size of 65 evaluable subjects will allow estimating the 95% confidence interval with a precision of +/- 7.9%. For the assumed rate and sample size, the lower bound of the confidence interval will be estimated to be larger than 80%. Assuming a 10% drop out rate, a total study size of 72 patients will be considered. This study is expected to open to recruitment in the third quarter of 2021. Clinicaltrials.gov #: NCT04786028.

Abstract Abstract 4600 Light chain deposition disease (LCDD) is a systemic disorder characterized by deposition of monoclonal light chains (LC) in different organs. A single clone of plasma cells is responsible for the overproduction of either kappa or rarely lambda LC. Renal dysfunction generally is the main feature but many organs could be affected. The treatment of LCDD has not been standardized and remains controversial because of the small number of patients reported in the literature. However, as LCDD is associated with plasma cell dyscrasias, patients have typically been treated with regimens used for multiple myeloma, most commonly melphalan (mel) and prednisone and VAD (Vincristine, Adriamycin and Dexamethasone). Here, we report our experience using High Dose Melphalan (HDM) with Autologous Stem Cell Transplant (ASCT) in five patients (pts) with LCDD. In addition, we report the use of Velcade (vel) as induction therapy in two patients before undergoing ASCT. Patients and Methods We retrospectively reviewed the records of all pts treated with HDM/ASCT at Princess Margaret Hospital between January 2004 and December 2009 and identified five pts with LCDD. Pretreatment evaluation included staging investigations: 1) complete blood cell counts, 2) complete biochemistry panel, 3) albumin and β2-microglobulin, 4) Blood and Urinary Monoclonal protein assessment including Free LC Assay; 5) skeletal survey. 6) Bone marrow aspirate and biopsy. Pts with LCDD and concurrent multiple myeloma were excluded. LCDD was diagnosed by renal biopsy in all pts with histology confirming characteristic linear monoclonal LC deposits along the tubular membrane staining for kappa and lambda chains on inmunofluorescence. All pts received induction therapy prior to consolidation with HDM/ASCT [dexamethasone (n=3) and vel plus dexamethasone (n=2)]. Assessment of hematologic response (HR) to treatment was based on modified EORTC consensus criteria. Results Pts characteristics are shown in Table 1. Two pts were male subjects; the median age was 55 (range 45–65). All five pts, had elevated serum FLC and an abnormal κ-to- λ ratio. All of the pts presented with kidney involvement. The monoclonal protein deposited in the kidney consisted of free κ-LC in four pts and free lambda LC in 1. Two pts received vel and dexamethasone (3 cycles) induction therapy achieving PR after 6 weeks of therapy and three received dexamethasone alone: 1 pt achieving a PR and 2 SD. All of them received a conditioning regimen of mel 200 mg/m2. Complete HR was seen in 3 pts and PR in 1 patient (ORR 80%, CR 60%). Transplanted pts had a median time to ANC ≥0.5 ×109/L of 12d (Range 12–13) and time to platelets ≥ 20 ×109/L was 14 days (Range 12–17). Median time to discharge was 17 days (range 13–30) and no pts exhibited engraftment syndrome. There was no mortality related to transplant. The most common grade 3/4 adverse events included: neutropenic fever (n=5); mucositis (n=2); and transient worsening in kidney function (n=1). All pts are alive and progression-free at a median follow-up of 20 months (range 7–37) from transplant. As kidney dysfunction represents the most prominent morbidity in LCDD, it is important to emphasize that the elevated serum creatinine was ameliorated in these pts after ASCT Conclusions LCDD is a rare condition and its management is controversial. In a few small series, investigators have reported that high-dose melphalan (HDM) followed by ASCT can be associated with beneficial results whereas toxicity remains acceptable in this group of pts. We report our experience using HDM and ASCT in pts with LCDD without concurrent myeloma, demonstrating feasibility and tolerability. Disclosures: Reece: Celgene: Honoraria, Research Funding.

Abstract Abstract 153 Introduction Modified R-hyperCVAD is a well-tolerated induction regimen with a high response rate in MCL. We hypothesized that the incorporation of bortezomib (Velcadea) into this regimen would enhance the complete response rates. We further hypothesized that the addition of maintenance rituximab (MR) would improve remission duration. The new regimen, VcR-CVAD with MR, was tested for safety and efficacy in the Eastern Cooperative Oncology Group. Methods Eligible patients had histologically confirmed, previously untreated MCL, PS 0–2, and adequate end organ function. The treatment plan included: bortezomib 1.3 mg/m2 days 1 and 4, rituximab 375 mg/m2 IV day 1, cyclophosphamide 300 mg/m2 IV over 3 hrs q 12 hrs × 6 doses days 1–3, doxorubicin 50 mg/m2 continuous infusion over 48 hrs days 1–2, vincristine 1 mg IV day 3, dexamethasone 40 mg po days 1–4. Cycles were repeated every 21 days for 6 cycles and all patients received G-CSF support. Patients achieving SD, PR, or CR received MR administered as 4 weekly treatments every 6 months for 2 years (protocol therapy). Patients could elect to receive high dose chemotherapy and autologous stem cell transplantation (SCT) off protocol rather than MR. The primary endpoint of the trial was the CR rate, defined as PET-negative, marrow-negative, to VcR-CVAD induction therapy. Results Seventy-five eligible patients were enrolled between 5/07 and 10/08. Baseline characteristics include median age 62 (40–76), 58M:17F, 92% stage III/IV, and 40% with elevated LDH. MIPI risk distribution included 37% low, 36% intermediate, 19% high, 8% unknown. Sixty-eight patients (91%) completed VcR-CVAD induction therapy. Reasons for treatment discontinuation included PD (1), toxicity (4), and patient preference (2). The ORR was 97% (73/75), CR rate 68% (51/75) and PR rate 29% (22/75). Of the 22 PR patients, 11 were so coded due to no bone marrow evaluation and/or PET imaging post therapy. The CR rate in the 64 completely restaged patients was 80%. Forty-four patients proceeded to protocol planned MR while 22 patients received SCT consolidation off protocol. With a median follow up of 3.6 years, the 3-yr PFS for the MR cohort (n = 44) and entire cohort (n = 75) are 73% and 74%, respectively. OS at 3-yrs is 88%, with no difference between MR and SCT patients. The major toxicity of the induction treatment regimen was expected myelosuppression. Grade 3–4 non-hematologic toxicities were rare. No patients developed grade 3–4 neuropathy. There were no serious toxicities during MR. There were no treatment related deaths. Conclusion The VcR-CVAD induction produced high overall OR (97%) and CR rates (68%) in a representative MCL patient population treated in a cooperative group setting. The 3-yr PFS (74%) and OS (88%) are highly encouraging. Remissions in patients receiving MR were as durable as patients receiving SCT consolidation. The value of bortezomib, when added to conventional chemotherapy, is currently being tested in a randomized intergroup trial (E1411).

Abstract Abstract 4265 Background: High-dose melphalan (MEL) followed by autologous stem cell support has been an integral component of multiple myeloma (MM) therapy since the 1980's. In general, high-dose melphalan is well-tolerated however grade 3 and 4 mucositis has been reported in up to 75% of patients (Lilleby et al. Bone Marrow Transpl, 2006). The efficacy of cryotherapy in preventing mucositis was initially documented in patients receiving infusional 5- fluorouracil (Rubenstein et al. Cancer, 2004). It is presumed that vasoconstriction reduces exposure of the oral mucosa to chemotherapy. Due to similar pharmacokinetic properties of melphalan including its short half life, cryotherapy has been used in MM patients undergoing MEL and stem cell transplant (SCT) with small series and one randomized trial supporting its use (Lilleby et al. Bone Marrow Transpl, 2006). At Memorial Sloan-Kettering Cancer Center, ice chips administered for 30 minutes before, during and after melphalan administration was adopted in March 2011 for all MM patients receiving MEL (≥ 140 mg/m2). In this study we sought to determine if the incidence of mucositis has been reduced since instituting cryotherapy into our standard practice. Methods: We retrospectively identified MM patients who received MEL 140 or 200 mg/m2 prior to SCT between January 1, 2009 and June 12, 2012 using our pharmacy database and electronic medical record. We analyzed two groups of patients by date of SCT and confirmed that patients transplanted prior to 3/2011 did not receive cryotherapy while all others did. Mucositis grade was recorded as documented by medical staff or determined by the investigators using the CTCAE version 4 criteria. Disease and treatment characteristics were collected in addition to narcotic use, total parenteral nutrition (TPN) requirement, and days of hospitalization. Fisher's exact test was used to compare the proportion of patients with mucositis, severe mucositis (defined as grade 3 or higher) and those requiring patient controlled analgesia (PCA), by cryotherapy use. Logistic regression was used to adjust for prior radiation and the number of prior lines of therapy. The number of hospital days was compared using a t-test. Results: During the study period, 214 patients underwent one or more autologous SCTs for MM; for patients who had more than one, only the initial SCT was included in this analysis. Of 214 patients, 85 (40%) received cryotherapy of whom 34% developed mucositis compared to 47% who did not receive cryotherapy (P = 0.08). Grade 3 mucositis was seen in 2% and 16% of patients who did and did not receive cryotherapy respectively (P = 0.004). No patient in either group developed grade 4 mucositis. After adjusting for radiation and lines of prior therapy the association between grade 3 mucositis and cryotherapy remained significant (OR: 0.13 (0.02, 0.47); P = 0.01). PCA use was lower in patients who received cryotherapy (19%) compared to those who did not (37%) (P = 0.01), with the median duration of use being 5 days in both groups. TPN was not required for any patient. Hospital days were similar in both groups (P = 0.88). Conclusion: Cryotherapy administration at the time of high-dose melphalan reduces the incidence of severe mucositis and PCA use. Cryotherapy is readily available and should be offered to all MM patients receiving ≥ 140 mg/m2 of melphalan.

Abstract Introduction In multiple myeloma, initially, there are increased numbers of osteoclasts showing increased activity, but bone formation by osteoblasts is keeping step. In later stages, parts of the bone remodeling compartments are disrupted by the interaction with myeloma cells leading to increased bone resorption which can no longer be compensated (myeloma bone disease, uncoupling of bone formation and bone resorption). Lenalidomide and bortezomib have been shown to target both, myeloma cells and the microenvironment: lenalidomide inhibits osteoclastogenesis, bortezomib is also able to stimulate osteoblast differentiation leading to increased bone formation. Aim of this study is to evaluate the impact of bortezomib-based induction treatment, high-dose therapy, and lenalidomide consolidation on alterations of bone turnover, i.e. surrogates of osteoblast- (osteocalcin, OC) and osteoclast- (collagen type I fragments, CTX-I) function, and their induction by myeloma cells (DKK1-level). Methods Serum was collected during routine sampling within the GMMG-MM5 trial (EudraCT 2010-019173-16), and levels of CTX-I, OC, and DKK1 were assessed by ELISA in triplicates using commercially available assays according to the manufacturer’s instructions (RnD Systems and Immunodiagnostic Systems). The following time points were assessed: at inclusion (n=365), after induction therapy with either PAd (n=88) or VCD (n=84), stem cell mobilization using CAD (n=69), high-dose melphalan (n=92), and 2 months lenalidomide consolidation (n=92). Up to now, serum samples of 69 patients were measured sequentially at five time points in line with the GMMG-MM5 trial. DKK1 levels were correlated with the expression in CD138-purified myeloma cells (Affymetrix microarrays, n=365). Results Prior to treatment, CTX-I levels are increased, those of OC decreased compared to healthy donors (uncoupled bone turnover). DKK1 protein levels are increased and correlate with DKK1-expression in myeloma cells. After induction therapy, osteoclast activity (CTX-I) is decreased below normal values. PAd unlike VCD further decreases osteoblast activity (OC-levels); DKK1-levels are normalized. Subsequent treatment further decreases DKK1-levels below normal values and blocks osteoclast function. After 2 months lenalidomide consolidation, no normalization of osteoblast activity is found. Conclusion The main impact on bone turnover by bortezomib-based induction treatment is a reduction of osteoclast activity alongside a decrease in DKK1-levels. During the reported period, no normalization of decreased osteoblast function was observed. Disclosures: Seckinger: Novartis Pharma: Research Funding. Goldschmidt:Novartis Pharma: Research Funding.

Abstract The phase 3 trial HOVON-50 was designed to evaluate the effect of thalidomide during induction treatment and as maintenance in patients with multiple myeloma who were transplant candidates. A total of 556 patients was randomly assigned to arm A: 3 cycles of vincristine, adriamycin, and dexamethasone, or to arm B: thalidomide 200 mg orally, days 1 to 28 plus adriamycin and dexamethasone. After induction therapy and stem cell mobilization, patients were to receive high-dose melphalan, 200 mg/m2, followed by maintenance with α-interferon (arm A) or thalidomide 50 mg daily (arm B). Thalidomide significantly improved overall response rate as well as quality of the response before and after high dose melphalan. Best overall response rate on protocol was 88% and 79% (P = .005), at least very good partial remission 66% and 54% (P = .005), and complete remission 31% and 23% (P = .04), respectively, in favor of the thalidomide arm. Thalidomide also significantly improved event-free survival from median 22 months to 34 months (P < .001), and prolonged progression free from median 25 months to 34 months (P < .001). Median survival was longer in the thalidomide arm, 73 versus 60 months; however, this difference was not significant (P = .77). Patients randomized to thalidomide had strongly reduced survival after relapse. This trial was registered on www.controlled-trials.com as ISRCTN06413384.

High Dose Melphalan

Abstract Single-agent high-dose melphalan followed by autologous stem cell transplantation (ASCT) remains a standard of care in eligible patients with multiple myeloma (MM). Efforts to improve transplant outcomes by intensifying transplant conditioning have mostly failed, with the exception of a sole phase III study showing improved progression-free survival (PFS) with the addition of busulfan to melphalan (Lancet Haematology 2019, 6:266-75). Bendamustine is a synthetic agent that combines the alkylating properties of a mustard-group with the antimetabolic activity of a purine analog. It can induce responses in MM resistant to other alkylators and is therefore a promising agent to test synergy in conditioning regimens. The high-dose chemotherapy combination of bendamustine, etoposide, cytarabine and melphalan (BeEAM) has been shown to be a safe and effective transplant regimen for lymphoma patients (Blood 2011, 118:3419-25). We performed a phase II study to test the safety and efficacy of BeEAM in MM patients, 18-70 years of age, with adequate organ function (EF≥40% predicted, CrCl ≥40ml/min) and within 9 months of starting induction therapy. Results were compared to a contemporaneously treated control group receiving a single high-dose melphalan 200mg/m2 transplant (Mel200) but otherwise meeting study eligibility criteria. Study patients (n=65) had a median (range) age of 59 (40, 69) years and were transplanted from 2015-2020. Other characteristics included KPS&lt;80%, HCT-CI≥3, ISS III, and high-risk FISH in 35%, 46%, 26% and 44% respectively. Pre-BMT status was (s)CR1, VGPR1, PR1 and &lt;PR1 in 26%, 43%, 26% and 5% respectively. ASCT following BeEAM was well tolerated with no non-relapse deaths through one-year post-transplant. Although at least one non-hematologic grade 3 toxicity was reported in 32 (49%) patients, there were no grade ≥3 renal or hepatic toxicity and no grade ≥4 non-hematologic toxicity. With a median f/u of 44 (13, 70) months, three-year OS and PFS was 92% and 57% respectively. When BeEAM patients were compared to contemporaneously treated Mel200 patients, there were no significant differences in baseline characteristics, induction regimen or use of post-transplant maintenance therapy. Neutrophil and platelet engraftment was faster following BeEAM (11 vs. 12 days, 17 vs 18 days, p&lt;0.001 and p=0.007 respectively), when compared to Mel200 patients. One-year non-relapse mortality was 0% with both BeEAM and Mel200. No significant differences were seen in quality of response, PFS or OS between BeEAM and Mel200, when analyzing either the whole cohort (see figure) or by genetic risk stratification. In multivariate analysis, controlled for genetic risk and year of transplantation, the use of BeEAM conditioning offered no benefit to Mel200 in terms of OS, PFS or risk of relapse/progression. In summary, BeEAM was shown to be a safe and effective conditioning regimen prior to up-front autologous transplant for MM. However, BeEAM conditioning appears to offer no significant advantage when compared to conventional Mel200 conditioning. Figure 1 Figure 1.

Abstract High-dose Melphalan (HDM) is the most commonly used conditioning regimen for autologous stem cell transplantation (ASCT) in newly diagnosed transplant-eligible Multiple Myeloma (MM) patients. Recent evidence suggests that the depth of response after induction therapy influences progression free survival (PFS) and, in most studies, overall survival (OS). Actually the effect of the inclusion of new drugs in the conditioning regimen for ASCT is still unknown. Phase I-II clinical study showed that the addition of Bortezomib (Bor) to HDM is safe and a promising conditioning regimen. Thus, in this study we analyzed a single center experience on the use of Bor in combination with HDM (Bor-HDM) as conditioning regimen before ASCT as frontline treatment in MM patients in order to evaluate the safety and the response rates of this combination regimen. We analyzed a total cohort of 48 newly diagnosed MM patients (25 females and 23 males; median age 60 years, range 42-70) admitted consecutively to our Bone Marrow Transplantation Center from 2008 to 2014. Regarding prognostic stratification, 25% of patients were classified as stage III according to International Staging System (ISS), and 12% exhibited high-risk cytogenetic features (defined by presence of del(17p) and/or t(4;14) and/or t(14;16)). All patients with the exception of three underwent to 3-drugs Bor-based induction therapy including Bor (median cumulative dose: 28.9 mg/m2), Thalidomide and Dexamethasone (VTD). After induction therapy and stem cell collection 28 out of 48 patients were treated with Bor-HDM, whereas 20 patients with HDM alone as conditioning regimen before ASCT. HDM was administered on day -2 (median dose: 200 mg/m2), and a single-dose Bortezomib at the dosage of 1.3 mg/m2 was administered on day -1 in the Bor-HDM group. Stem cells were reinfused on day 0 (median number of CD34+ infused: 3.3x106/Kg, range 1.86-6x106/Kg). Responses were evaluated at day 100 after ASCT, and definitions of response were used according to the International Myeloma Working Group (IMWG) Uniform Response Criteria for MM. Quantitative variables were compared by non-parametric Kruskal-Wallis and Mann-Whitney tests as appropriate and categorical variables were analyzed by Chi-square and Fisher's exact test. pvalue of <0.05 was considered significant. Any significant difference was not observed between Bor-HDM group vs HDM group, regarding age at diagnosis (p=0.77), sex (p=0.24), cumulative induction dose of Bortezomib (p=0.42), dose of Melphalan used for conditioning (p=0.16) and the median number of CD34+ cells infused (p=0.12). Distribution of ISS stage was similar in the two groups (p=0.14), as well as that of high-risk cytogenetic (p=0.14). Moreover the response rates after the induction therapy was not statistically different in the two groups of patients analyzed (sCR + CR: 19% in Bor-HDM group vs 26% in HDM group; VGPR: 33% vs 48%; PR: 48% vs 26%, p=0.22). Any significant difference on hematopoietic recovery rates was not observed in Bor-HDM as compared to HDM alone with a mean time to neutrophil recovery of 12 days (range 9-18) and to platelet recovery of 12 days (range 9-21) in both groups. Bor-HDM conditioning was well tolerated, without increase of neuropathy occurrence. Then we analyzed the response rate after ASCT, showing that the overall response rate (ORR) was significantly higher in Bor-HDM group as compared to HDM (sCR+CR: 56% in Bor-HDM vs 17% in HDM; VGPR 30% vs 28%; PR: 15% vs 56%, p=0.0072) with a higher number of "good quality" response (sCR + CR + VGPR: 86% vs 45%; p=0.0075). The number of sCR was also significantly higher in Bor-HDM as compared to HDM alone (23% vs 0%, p=0.067). Moreover an improvement of the response rate after ABMT was seen more frequently in the Bor-HDM group as compared to the HDM group (p=0.0063). We then observed that the number of patients that underwent tandem ASCT was higher in the HDM group (66% vs 41%), even not reaching a statistical significance. In conclusion, this retrospective analysis suggests that BOR-HDM is safe as conditioning regimen with a higher response rate after ASCT as compared to the standard HDM regimen giving the rational design for randomized studies needed to assess whether this conditioning regimen is superior to HDM alone.

Abstract Background: Arsenic trioxide (ATO) has been shown to be synergistic with melphalan both in vitro and in vivo. We conducted a randomized phase II trial to determine the safety and efficacy of a combination of ATO, melphalan, and ascorbic acid (AA) as a preparative regimen in patients undergoing autologous hematopoietic progenitor cell transplantation for multiple myeloma (MM). We also assessed the impact of ATO levels on melphalan pharmacokinetics, engraftment, and toxicity. Methods: Forty-eight patients with secretory myeloma (23 females, 25 males; median age, 54; range 35–70) were treated between 4/04 and 8/05. All patients received melphalan 100 mg/m2 IV on days -4 and -3 and AA 1000 mg/day IV on days -9 to -3. Patients were randomized to 3 arms: no ATO (arm 1), ATO 0.15 mg/kg IV on days -9 to -3 (arm 2), and ATO 0.25 mg/kg IV on days -9 to -3 (arm 3). Twelve patients had received a prior autograft, with a median 4.5 x 106/kg (range 2.3–10.9) CD34+ cells infused. Results: Patients in all 3 arms were evenly matched. Twenty-nine patients (60%) were transplanted for consolidation of first remission and 19 patients (40%) for relapsed disease. With a median follow-up of 26 months (range 10–37) post-autograft, no dose-limiting toxicity, or nonrelapse mortality was reported. Toxicity was limited to grade 1 or 2 nausea, vomiting, and diarrhea and was comparable in all 3 arms. Melphalan pharmacokinetics was not altered by ATO pretreatment. Median time to neutrophil engraftment (absolute neutrophil count >500/dL) was 9 days, with no engraftment failures or delays in either the control or ATO arms. The complete response (CR) rate for all patients was 25% (12/48), and the partial response rate was 60% (29/48) for an overall response rate (ORR = CR + PR) of 85%. Progression-free survival (PFS) and overall survival (OS) after 24 months of follow-up were 59% and 91%, respectively. Median PFS was 29 months; median OS has not been reached. There was no significant difference in CR, ORR, PFS, or OS among the 3 arms (P =.9, .9, .5, and .6, respectively). PFS and OS were comparable among patients with chromosomal abnormalities or relapsed disease at transplant and patients undergoing a second autotransplant for salvage. Conclusions: Addition of ATO + AA to high-dose melphalan is safe and well tolerated as a preparative regimen for autotransplants in patients with MM, including high-risk patients. There was no adverse impact of ATO on engraftment. Longer follow-up is necessary to assess the efficacy of this combination on PFS and OS.
