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.

Background: Treatment for primary CNS lymphoma involves a methotrexate-based induction therapy followed by consolidation. The optimal consolidation treatment after induction with a high dose Methotrexate (HD-MTX), Rituximab and Temozolomide regimen has not been fully established. The CALGB 50202 regimen using Etoposide and Cytarabine consolidation was associated with significant toxicity. We sought to review the results of alternative consolidation regimens and evaluate the progression free survival and overall survival. Methods: A retrospective cohort study was conducted to evaluate the efficacy of alternative consolidation regimens such as autologous stem cell transplant and HDMTx alone. Patients diagnosed with primary CNS lymphoma between November 2012 and March 2019 were identified. All patients received the same induction chemotherapy based on the CALGB 50202 protocol. Data was collected for baseline characteristics, progression free survival and overall survival. Results: 38 patients had a diagnosis of primary CNS lymphoma. 15 patients received treatment as per the CALBG 50202 induction protocol with high dose Methotrexate, Rituximab and Temozolomide. Of the 15 patients, 11 patients (69%) achieved a complete remission (CR) after induction therapy. 7 patients received an autologous stem cell transplant for consolidation, 5 patients received HD-MTX alone for consolidation and one patient was placed on Lenalidomide maintenance. 2 patients did not receive any consolidation therapy due to progressive disease and/or death. At a median follow up of 2.7 years for the entire cohort, median PFS was 31.7+ months and median OS was 32.5+ months. At a median follow up of 2.7 years for patients who were consolidated with an autologous stem cell transplant, median PFS and median OS was 27.2+ and 32.5+ months respectively. At a median follow up of 5.5 years for patients who were consolidated with treatments other than transplant, median PFS and OS was 65.6+ months. There were no deaths attributed to treatment related toxicity. To date, 4 patients of the entire cohort have died, with a median survival time among surviving patients of 3.6 years (range, 0.68-7.05 years). There were no deaths attributed to treatment related toxicity. Conclusion: Patients with primary CNS lymphoma who received induction therapy as per CALGB 50202 regimen and received alternative consolidation therapies with either autologous stem cell transplant or HD-MTX based consolidation achieved prolonged PFS and OS comparable if not superior to the Etoposide and Cytarabine consolidation. Results of the ongoing CALGB 51101 trial will determine the utility of EA consolidation. Disclosures No relevant conflicts of interest to declare.

Abstract Double hit lymphoma (DHL), defined as B cell lymphoma with a c-MYC rearrangement plus a IGH/BCL2 rearrangement, confers a poor prognosis. Outcomes with R-CHOP are dismal with reported 2 year EFS <30% in multiple series. To improve upon these results, Burkitt type regimens such as R-HyperCVAD and dose adjusted (DA) R-EPOCH have been attempted, but 2 year EFS remains < 50% in early reports. In addition, the SWOG-9704 study found a benefit for consolidative autologous stem cell transplant (autoSCT) in high risk DLBCL, likely including some DHL, although this reported benefit has not been confirmed in three other randomized European studies. Since 2010 the treatment algorithm at Oregon Health & Science University for fit patients with DHL has been DA-R-EPOCH followed by consolidative autoSCT in responding patients. Here we report the first 16 patients treated with consolidative autoSCT. At diagnosis, the median age was 58, and the median IPI was 3. All patients had rearrangements of c-MYC and IGH/BCL2. One of the c-MYC rearrangements was a classical t(8;14); the translocation partners in the other cases were unknown. Three patients also had a ‘triple hit’ with an additional BCL6 rearrangement. Fourteen patients received DA-R-EPOCH with intrathecal prophylaxis for induction. One received R-CHOP at another institution, and one received R-HyperCVAD. 15 of 16 patients were in CR after induction. Stem cell mobilization was performed with G-CSF +/- plerixafor, and BEAM was utilized as the high dose conditioning regimen. With a median follow-up of 18 months, the estimated 2 year PFS is 91 %, and the 2 year OS is 91 % in the 16 patients who underwent consolidative autoSCT. There were no deaths from non-relapse mortality, and the only relapse was 6 months post-transplant. All other patients undergoing autoSCT remain alive and in remission. An additional 15 patients also underwent induction with DA-R-EPOCH but did not proceed to autoSCT. Four patients who had intended to undergo autoSCT were refractory to induction. Of the remaining 11 patients, 9 did not pursue autoSCT because of age and/or comorbidities, and 1 each declined out of personal preference or insurance denial. Four of these 11 have relapsed or died. Our results suggest that consolidative autoSCT, especially after DA-R-EPOCH induction, is an effective treatment strategy for DHL in fit patients and should be explored in prospective studies.

Abstract Introduction: The optimal treatment approach for systemic AL amyloidosis remains unclear. Autologous stem cell transplant (ASCT) is the only modality associated with long term survival, but failure to show survival benefit in randomized clinical trial raises doubts about its efficacy 1, 2. Outcomes after ASCT are better in patients who achieve complete hematologic response after the ASCT3. One report has shown improved outcomes with combining one dose of the proteasome inhibitor bortezomib with high dose melphalan as part of conditioning regimen 4. Preliminary data from a recent study suggest that the outcome of treating AL amyloidosis with two cycles of bortezomib and dexamethasone followed by ASCT was superior to the outcome of the ASCT alone5. We describe our experience with giving 4-6 cycles of bortezomib and dexamethasone induction prior to high dose melphalan and ASCT in patients with systemic AL amyloidosis. Patients and methods: We included all patients who underwent autologous transplant for symptomatic systemic AL amyloidosis at our institution from October 2010 till June 2014. Five patients were included in the analysis and patient characteristics are described in table 1. All patient received 4 -6 cycles of induction with bortezomib and dexamethasone followed by autologous stem cell transplant using high dose melphalan (200 mg/m2). One patient also received six cycles of lenalidomide and dexamethasone prior to bortezomib based induction for lack of response. Hematologic and organ response were assessed using the definitions from the 10th International symposium on Amyloid and Amyloidosis. Overall survival was calculated by Kaplan Meyer’s method using Graphpad Prism 6.0 software. Results: There was no transplant related mortality. After median follow up of 13 months (12-25 months) all patient are alive. Toxicities from the ASCT were mostly cytopenias in the immediate post-transplant period which were managed as per the standard of care. Two patients achieved hematological complete response while one more had very good partial response and other two achieved partial response. Of the four patients with nephrotic range proteinuria, two patients had > 95% reduction in proteinuria, one had > 75% reduction in proteinuria and another patient had > 50% reduction in proteinuria. One patient had Liver involvement with elevated alkaline phosphatase which normalized post-transplant (table 2). The responses were maintained on last follow up and none of the patient had hematological or organ relapses. Discussion: Bortezomib alone and in combination with steroids has shown efficacy in AL amyloidosis, but its role in induction prior to high dose melphalan/ASCT to help achieve deeper hematological response is unknown. Our experience shows that this combination may be highly efficacious without significant toxicity. Limitations of our study include the small number of patients and absence of any patients with cardiac involvement, which is a worse prognostic marker. We conclude that the bortezomib and dexamethasone induction followed by high dose melphalan/ASCT for AL amyloidosis should be studied in prospective trials.

Abstract Background Both primary central nervous system lymphoma (PCNSL) and non-Hodgkin lymphoma (NHL) with CNS involvement carry a poor prognosis. While there has been interest in intensification of treatment with high-dose chemotherapy and autologous stem cell transplant (ASCT), the side effect profile and long-term efficacy of consolidative transplant are not yet clear. Our aim was to investigate the efficacy and safety of a conditioning regimen of thiotepa, busulfan, and cyclophosphamide (TBC) (Soussain C., et al, J. Clin. Oncol., 19:742-749, 2001) followed by ASCT in patients with PCNSL or NHL with CNS involvement. Methods A retrospective analysis was performed among consecutive patients undergoing consolidative ASCT with TBC conditioning for PCNSL or NHL with CNS involvement between July 2006 and December 2017. For patients with PCNSL, a uniform induction therapy was given that consisted of rituximab and high dose methotrexate for 2-4 cycles followed by rituximab / cytarabine / thiotepa for 1-2 cycles based on published data (Illerhaus et al, Blood 120, no. 21 (2012): 302). For patients with secondary CNS lymphoma or relapsed disease, a variety of chemotherapy regimens were used at the discretion of the treating physician. Progression-free survival (PFS) was defined from the date of transplant to the date of relapse or any cause of death. Overall survival (OS) was calculated from the date of transplant to death. Results Forty-eight patients with NHL who underwent ASCT with TBC conditioning were identified: 27 patients with PCNSL, 12 patients with secondary CNSL, and 9 patients with relapsed disease with CNS involvement. Twenty-nine patients (60%) were in their first complete response (CR1) at the time of transplant. The median time from diagnosis to transplant was 7.1 months (range 3.7- 144.4). The median follow-up time after transplant was 23.9 months (range 8.6 - 59.6 months). The median time to neutrophil recovery (absolute neutrophil count > 500/uL) and platelet recovery (>20,000 x 103/μL for > 2 consecutive days) were 9 days (range 7-12 days) and 7 days (range 1-40 days), respectively. Four patients were noted to have anemia (hemoglobin decrease >2 g/dL from baseline). Most patients (89.5%) experienced febrile neutropenia and 68.6% were found to have infection. Other common side effects included mucositis (89.5%, 35.4% with grade 3 or higher), electrolyte abnormalities (89.5%), dermatologic sequelae (31.3%), reversible neurotoxicity (18.8%), renal injury (16.7%), and hemorrhagic cystitis (8.3%). Four patients (8.3%) experienced treatment-related mortality, 3 of which had secondary CNSL. No evidence of pulmonary toxicity or veno-occlusive disease was noted. The 1-year PFS was 78% (95% CI 63.3%-88.0%), and 1-year OS was 80.5% (95% CI 66%-89.8%). When analyzed according to primary diagnosis, 1-year PFS was 82.6% for PCNSL, 70% for secondary CNSL, and 75% for relapsed disease with CNS involvement (p = 0.69). According to diagnosis, 1-year OS was 87% for PCNSL, 70% for secondary CNSL, and 75% for relapsed disease with CNS involvement (p = 0.47). Univariate analysis was performed to analyze gender, ethnicity, age > 60, Karnofsky score ≥ 80, diagnosis, cell of origin, and transplant in CR1 versus CR2 or partial response as independent predictors of PFS and OS. Only age (p = 0.001, 95% CI 1.9-42.6 for PFS; p = 0.030, 95% CI 0.99-23.42 for OS) and Karnofsky score ≥ 80 (p = 0.017, 95% CI 0.07-0.81 for PFS; p = 0.047, 95% CI 0.06-1.03 for OS) were found to be significant. Conclusion High dose chemotherapy and autologous stem cell transplant using TBC conditioning for PCNSL and secondary CNSL appears to have encouraging long term efficacy with manageable side effects. Future studies looking at longer follow-up periods and comparison with other conditioning regimens is warranted.

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.
