Myeloma is characterized by the neoplastic proliferation of a clone of plasma cells that invades the bone, causes destruction of the skeleton, and causes bone pain and fractures. In addition, other important features are anemia, hypercalcemia and renal failure. The standard treatment in Spain for autologous stem cell transplant (ASCT)-eligible patients is VTD (bortezomib, thalidomide, dexamethasone). Both bortezomib and thalidomide can cause or exacerbate an existing neuropathy. The mechanism by which they produce it is different in the two drugs.1 A 52-year-old white male was referred to our hospital for the evaluation of anemia (12 g/dL) and serum monoclonal protein (>4 g/dL). The diagnosis was a high cytogenetic risk MM stage R-ISS IIIA, without bone lesions. He only presented mild anemia. He started treatment with standard doses and in accordance to the usual protocol in a candidate patient for autologous stem cell transplant, based on a thalidomide and bortezomib scheme. On the 15th day of the 2nd cycle, the patient showed an autonomic neuropathy and an affectation of the deep sensibility, predominantly the vibratory and proprioceptive with generalized muscle weakness predominant in the lower limbs. He had no pain. He was totally dependent for the basic activities of daily life. Regarding the MM response, the patient showed a strict complete response. This case illustrates a young man with a high cytogenetic risk MM who developed an acute and early polyneuropathy grade IV after 1.5 cycles of standard treatment and with myeloma in strict complete response. The remarkable aspect about this case is the severe and early neuropathy, and an early, deep and persistent myeloma response. On some occasions this relationship has been reported, and we report an example of it.

8516 Background: There is consensus that light chain amyloidosis (AL) patients with CRAB criteria (abnormal calcium or renal function, anemia or lytic bone lesions) also have multiple myeloma (MM). These patients are typically excluded from AL trials; however, AL patients with >= 10% bone marrow plasma cells (BMPC) in the absence of CRAB are included in trials along with AL with < 10% BMPC. We postulated that the currently used dichotomy may be incorrect and examined the spectrum of AL with and without MM. Methods: We identified 1,272 patients with AL seen within 90 days of diagnosis, between January 1, 2000, and December 31, 2010. We defined the population of patients with coexisting MM based on the existence of CRAB (AL-CRAB-MM). Patients without CRAB were divided into two groups, AL-only (<10% BMPC) and AL-PC-MM (>=10% BMPC). Results: Among the 1,272 patients, 117 (9%) had AL-CRAB-MM, 476 (37%) had AL-PC-MM, and 679 (53%) had AL only. Their respective median overall survivals (OS) were 16.2, 15.8, and 28.4 months (p<0.0001). Autologous stem cell transplant (ASCT) was performed in 203 (30%), 138 (29%) and 23 (20%) patients respectively. Since the outcomes of AL-CRAB-MM and AL-PC-MM were similar, they were pooled for univariate and multivariate analyses. On multivariate analysis, AL-CRAB-MM and AL-PC-MM retained negative prognostic value independent of age, cardiac stage, prior autologous stem cell transplant (ASCT), beta 2 microglobulin, and dFLC. We next considered whether patients received ASCT as part of their treatment. For those patients who never received ASCT, the 5-year OS were 19%, 14%, and 31%, p<0.001, for AL-CRAB-MM, AL-PC-MM, and AL only respectively. In contrast, for those patients who received ASCT, the respective 5-year OS were 46%, 56%, and 73%, p<0.001. Conclusions: AL patients with >=10% BMPCs have a poor prognosis similar to patients with AL-CRAB-MM and should therefore be considered as AL with MM.

Landmark Analyses

Abstract Autologous stem cell transplant (ASCT) is highly effective in selected patients with light chain (AL) amyloidosis. Bortezomib, preceding or following ASCT, improves responses. Satisfactory responses, including at least a partial response, very good partial response (VGPR) with organ response, or complete response, can be observed after induction therapy alone. We report 139 patients treated upfront with cyclophosphamide/bortezomib/dexamethasone (CyBorD), followed by ASCT only if response was unsatisfactory. Only 1 treatment-related death was observed. After CyBorD, hematologic response (HR) rate was 68% (VGPR or better, 51%), with 45% satisfactory responses. Transplant was performed in 55 (40%) subjects and resulted in an 80% HR rate (65% ≥ VGPR). Five-year survival was 86% and 84% in patients treated with ASCT or CyBorD alone, respectively (P = .438). Also, 6- and 12- month landmark analyses did not show differences in survival. Duration of response was not different in the 2 groups (60 vs 49 months; P = .670). Twenty-one (15%) patients with an unsatisfactory response to CyBorD could not undergo ASCT because of ineligibility or refusal; instead, they received rescue chemotherapy, with HR in 38% of cases and 51% 5-year survival. This sequential response-driven approach, offering ASCT to patients who do not attain satisfactory response to upfront CyBorD, is very safe and effective in AL amyloidosis.

Abstract Introduction: Autologous stem cell transplant (ASCT) as part of initial therapy has been shown to prolong survival of patients with multiple myeloma, with some achieving durable complete remission. However, the majority of patients ultimately relapse after ASCT and require salvage treatment. Options for the treatment of such patients have increased significantly over recent years, including not only novel chemotherapeutic and biological agents but also additional ASCTs. We performed a retrospective analysis of our experience with salvage ASCT for multiple myeloma to determine which clinical variables influence outcome. Methods: Between October 1992 and February 2005, we performed 342 ASCTs for multiple myeloma. Twenty-six of these were salvage transplants for relapsed disease after prior ASCT, and all were included in the analysis. Patients who received two planned (tandem) ASCTs were not included. Results: The median age at diagnosis was 47 (range 25–66), and median ISS and DS stages at diagnosis were 1 and 2, respectively. The initial ASCT was melphalan-based in 21/26; six (23%) achieved a complete response (CR) to the initial transplant, and fifteen (58%) achieved a partial response (PR). The median event-free survival (EFS) after the initial transplant was 19.5 months (range 2–60). The median time between initial and salvage ASCT was 2.6 years (range 0.3–7.6). Twenty-two patients (85%) received non-transplant therapy between ASCTs, and the median number of lines of therapy prior to salvage ASCT was 3. At the time of salvage ASCT, the median age was 52.5 (range 28–69). Fourteen patients received melphalan alone, eight received melphalan/TBI, and four received other regimens. Eleven patients (42%) achieved a response to therapy (1 CR, 10 PR). One patient (4%) died of transplant-related toxicity. The median follow-up after salvage ASCT is 12 months (range 0.2–58). Median EFS is 9 months, and median overall survival (OS) is 36 months. The 2-year EFS is 14%, and 2-year OS is 52%. On univariate analysis, both response to and EFS after initial transplant significantly predict improved EFS after salvage transplant (p=0.0008 and p=0.0065 respectively). Both also predict improved OS (p=0.03 and 0.0005 respectively). A greater than 12 month interval between first and second transplant also correlated with OS (p=0.04). There was no significant difference in EFS or OS by preparative regimen. Interestingly, type of response to the salvage transplant (CR/PR or less than PR) did not predict improved EFS or OS. Conclusion: This study suggests that salvage ASCT after relapse from initial ASCT is a feasible therapy for patients with heavily treated multiple myeloma, particularly those with a prolonged response to the first transplant.

Abstract Abstract 1858 Systemic light chain amyloidosis (AL amyloidosis) is a condition where clonal plasma cells produce misfolded insoluble immunoglobulin light chains that deposit in various organs causing progressive organ dysfunction. Chemotherapy and autologous stem cell transplant (ASCT) when eligible is the standard treatment options for patients with AL amyloidosis. There are several studies who report long term outcomes of patient post ASCT. However, there is a paucity of literature describing the outcomes of patients who have received ASCT but have relapsed. We performed a retrospective study to assess the outcomes and treatment regimens employed following relapse after ASCT. Between 1996 and 2009, 410 patients received ASCT at the Mayo Clinic as first line therapy. Of those 410 patients 42 patients died within 3 months of transplant, 64 patients died without documented relapse, 158 patients were alive without documented progression, and 146 patients had documented progression. Those 146 patients are the subject of our study. The median time to hematologic relapse was 2 years (range: 0.2–15.5 years). At relapse, 59 patients were treated with IMiD based therapy, 36 with alkylator based therapy, 24 with bortezomib, 15 with steroids, and 5 with second ASCT. The respective hematologic response rates were 58%, 33%, 50%, 53%, and 60%. The remaining six patients were not evaluable for response for one other following reasons: organ transplants; no further therapy; inevaluable disease. With a median post relapse follow up of 3.6 years, the median overall survival (OS) from the first post ASCT relapse was 4.6 years. The median post transplant follow up was 6.1 years, the median OS for these patients was 7.3 years from the time of transplant. These data provide novel information about outcomes after SCT relapse, which should be useful not only for patients and doctors but also for investigators designing studies for salvage therapies post-transplant.

Abstract Abstract 4587 Background: High-dose chemotherapy and autologous stem cell transplant (ASCT) remains an important therapeutic modality for MM patients. Traditionally high-dose single agent melphalan (200 mg/m2; Mel-200) has been used as the conditioning regimen prior to ASCT for MM. We investigated the combination regimen of BCNU, etoposide and melphalan (BEM) in this setting at our center. Methods: All patients who had undergone ASCT for MM utilizing BEM conditioning regimen at Norris Cancer Center, University of Southern California, Los Angeles were eligible. BEM consisted of BCNU 12 mg/kg (actual body weight or ideal body weight whichever was lower) iv on day -5, etoposide 60 mg/Kg iv on day -3, and melphalan 140 mg/m2 iv on day -1, prior to stem cell reinfusion on day 0. Overall survival (OS) was defined as time from MM diagnosis to death, or in patients still alive, the date of last follow-up. Progression-free survival (PFS) was defined as time from ASCT to date of relapse, or in patients without documented relapse, date of death or last follow up, whichever was sooner. Survival for patients with different clinical and disease-specific characteristics was explored using logrank test. Response was assessed according to International Uniform Response Criteria for MM. Results: A total of 44 MM patients underwent ASCT utilizing the BEM conditioning regimen. Of these, evaluable data was available for 42 patients (25 males; 60%, 17 females; 40%) with a median follow up of 27.6 mths. Median age at diagnosis was 54.5 yr (range 34–68) while median time from MM diagnosis to ASCT was 10.5 mths (range 2.8–47.8). MM subtypes included IgA (n=5, 12%), IgG (n=30, 71%) and light chain-only (n=7, 17%). Median bone marrow (BM) plasmacytosis at diagnosis was 42.5% (range 0%-100%). Durie-Salmon (DS) stages included stage I (12%), II (36%) and III (52%), while 4 patients (10%) had renal dysfunction at the time of initial MM diagnosis. Majority of the patients (71%) had lytic bone lesions at the time of diagnosis and 86% (n=36) hade secretory disease. Patients had received a median of 1 prior treatment (range 1–5), while 23 (55%) patients had received novel agents (proteasome inhibitors or IMiDs) prior to the BEM regimen. Response rates prior to and after the regimen are summarized in Table 1. After BEM-ASCT an additional 16 (38%) patients achieved a CR. Median duration of hospitalization and time to engraftment were 19 days (range 15–41) and 10.5 days (range 7–19), respectively. One patient died prior to discharge from the hospital post ASCT (Day 36 post ASCT) for a treatment related mortality of 2%. CR rate post BEM-ASCT was 64% with an ORR of 97%. Relapses have been noted in 25 patients to date. Median OS for all patients was 4.9 yrs (5.6 yrs for patients in CR and 6.6 yrs for patients in PR after BEM-ASCT). Median PFS was 23.9 mths for all patients (25 mths for patients in CR and 21.8 mths for those in PR after BEM-ASCT). No statistically significant differences were noted in OS based on patient gender (p=0.47), age at diagnosis (< or ≥60 yr), MM subtype (p=0.52), DS stage at diagnosis (0.09), patients without lytic bone lesions at diagnosis (p=0.054), secretor status (p=0.2), response status at the time of BEM-ASCT (p=0.9) or prior exposure to novel agents (p=0.62). Conclusions: BEM is a well-tolerated conditioning regimen prior to ASCT in MM and has efficacy comparable to Mel-200. BEM can be effectively employed in patients where Mel-200 is not feasible. We are particularly intrigued by its ability to deliver high CR rates (64%) compared to <30% (historical control). Very encouraging median OS (4.9 yr) and PFS (23.9 mth) rates were noted which were even better in patients who had a measurable response after this regimen. Further investigations will be needed to optimally define its potential as standard conditioning regimen in MM patients undergoing ASCT. Disclosures: No relevant conflicts of interest to declare.

In patients who experience relapse of multiple myeloma, upwards of 30% can have extramedullary disease. The presence of extramedullary multiple myeloma is typically associated with adverse cytogenetics and a poor prognosis. Organs most commonly involved include the liver, skin, central nervous system, pleural effusions, kidney, lymph nodes, and pancreas. We present the case of a 53-year-old man with IgA kappa multiple myeloma with the adverse cytogenetic findings of t(4;14) and 1q21 gain who had achieved a stringent complete (sCR) response after initial therapy with carfilzomib, lenalidomide and dexamethasone. Stringent complete response is defined as the normalization of the free light chain ratio in the serum and an absence of clonal cells in the bone marrow in additiion to criteria needed to achieve complete response. Prior to undergoing a planned autologous stem cell transplant, this patient experienced cardiac tamponade secondary to extramedullary relapse of his multiple myeloma which was limited to the pericardium. In response, his treatment regimen was transitioned to pomalidomide, bortezomib, dexamethasone and cyclophosphamide for three cycles after which he again achieved sCR and ultimately underwent autologous stem cell transplant. Post-transplant consolidation therapy was administered in the form of pomalidomide, bortezomib and dexamethasone, followed by pomalidomide and bortezomib maintenance, which he has continued to receive for 3 years without evidence of disease progression.

Abstract Abstract 2042 Background: Given data showing efficacy of bendamustine in treating multiple myeloma (MM), with the known toxicity profile significant for myelosuppression, we hypothesized that the addition of bendamustine to autologous stem cell transplant (ASCT) conditioning would enhance response without significant toxicity change. We now report the results of a phase 1 study of bendamustine + melphalan conditioning ASCT in MM. Methods: 21 patients were enrolled onto a 3+3 phase 1 study of bendamustine added to melphalan 200mg/m2 split on subsequent days at the following dose levels on the indicated days of melphalan: 1) 30 mg/m2 given on day 2; 2) 60 mg/m2 on day 2; 3) 90 mg/m2 on day 2; 4) 60mg/m2 on days 1 and 2; 5) 90 mg/m2 on day 1 and 60mg/m2 on day 2; 6) 125 mg/m2 on day 1 and 100mg/m2 on day 2. Stem cell infusion of > 2 million × 106 CD34+ cells/kg was performed at 24–48 hours after final chemotherapy. Patients received G-CSF with standard supportive care until engraftment, defined as absolute neutrophil count > 500/ml and a platelet count > 20,000/ml. Bone marrow biopsy and skeletal imaging were prior to and 100 days after ASCT to assess baseline and post-ASCT disease status. Disease response evaluation was performed monthly with immunoelectrophoresis and free light chain analysis in accordance with international uniform myeloma reporting criteria. Results: Twenty-one patients completed ASCT over 6 cohorts: 3 in dose level 1, 6 at dose level 2, and 3 each in dose levels 3, 4, 5, and 6. Median number of days (range) to wbc engraftment and platelet engraftment was 11 (9–13) and 12.5 (10–22), respectively. Toxicities were graded according to the Bearman scale. There was only one Grade 3 toxicity: a patient with respiratory decompensation in the setting of neutropenic fever in cohort 2 (a pulmonary dose limiting toxicity-DLT). Other toxicities noted in patients (%) (Grade 1 / Grade 2 respectively) were Cardiac: 6 (29%) / 2 (10%); Pulmonary 1 (5%) / 1 (5%); CNS 0 / 1 (5%); Stomatitis 15 (71%) / 0; GI 10 (48%) / 1 (5%). The CNS toxicity was narcotic-related psychosis. Eight patients had neutropenic fever, with 3 cases of bacteremia. No transplant-related mortality occurred. At present, there are 18 evaluable Day +100 myeloma responses: disease progression in 5 (24%), stable disease in 1 (6%), partial response 1 (6%), very good partial response in 2 (11%), and complete response in 9 (50%). Four patients (19%) died from MM, all with disease progression at 100 days post-ASCT, and all with pre-existing extramedullary disease. Summary: Bendamustine added to ASCT conditioning in MM does not exacerbate expected toxicities. The maximum tolerated dose of bendamustine in combination with melphalan 200mg/m2 was not found after a series of 6 treatment cohorts. The relatively high complete response rate and good regimen tolerability has prompted an extension phase 2 trial at the cohort 6 dosing to further evaluate regimen efficacy. Disclosures: Off Label Use: The study evaluates bendamustine safety in transplantation for myeloma; there is no FDA-label for this. Niesvizky:Merck: Research Funding.
