8022 Background: Autologous stem cell transplant (ASCT) is the standard approach for eligible patients (pts) with multiple myeloma (MM). The median time to relapse after early ASCT is 2–3 yrs and overall survival (OS) is 4–5 yrs. Though various risk factors have been identified for early relapse, the outcome of this group of pts is not clearly described. With the advent of newer therapies, it is important to understand the natural history of MM in these pts to design treatment strategies. Methods: A total of 432 pts with MM, undergoing ASCT within 12 months (mos) of diagnosis, with a minimum follow up of 12 mos were studied. Clinical and laboratory data were obtained from a prospectively maintained database and clinical records. Pts were divided into 2 groups: early relapse (relapse <12 mos from ASCT) and late relapse (either relapsed >12 mos after ASCT or disease free at last follow up). Results: There were 94 pts (22%) in the early relapse group and among the late relapse group (N=338), 171 had relapsed beyond 12 mos and 167 were disease free at last follow up. The median time to ASCT was similar in all groups. The early relapse group had a significantly shorter median OS from diagnosis (23.9 vs. 82.2 months; P < 0.001) and from transplant (17.6 mos vs. not reached; P < 0.001). The median OS from relapse was 7.9 mos in this group compared to 39.6 months for the rest. In univariate analysis, elevated CRP, high BM plasma cell%, labeling index (PCLI) >1%, abnormal cytogenetics, presence of circulating PCs at harvest and lack of CR from ASCT predicted for early relapse. In multivariate analysis, an elevated PCLI (RR=2.9; P=0.002) and failure to achieve CR (RR 2.7; P=0.002) was associated with early relapse. Conclusions: Pts who relapse within 12 mos of an ASCT have a very short survival and should be offered trials evaluating novel therapies and combinations. Survival figures from this study represent the benchmark for the comparison of novel approaches in this population. Pts with poor prognostic factors have a short PFS after ASCT and should be considered for alternative approaches. Inability to achieve CR appears to predict shorter PFS and clinical trials evaluating maintenance therapy should be offered in these pts. No significant financial relationships to disclose.

Abstract Background: Patients (Pts) with multiple myeloma (MM) who relapse within 12 months of autologous stem cell transplantation (SCT) have a poor prognosis. As reported by Mahmood et al. (ASCO 2007), of 432 pts who received SCT at the Mayo Clinic between 1994–2005, those with early relapse within 12 months (94/432– 22%) showed poorer median overall survival. Kaplan-Meier estimates of 12-month survival from the date of first relapse were 37% for pts relapsing within 12 months after SCT as compared to 85% for those relapsing after 12 months. In that study, pts had received regimens other than B. In a recent report of a large, phase III study (DOXIL-MMY3001), the combination of PLD+B improved time to progression (TTP) as compared to B alone (Orlowski et al. JCO 2007). The present analysis examined the 12-month post-randomization survival of patients who had early (<12 months) vs. late (≥12 months) relapse following SCT, as well as the effect of PLD+B vs. B alone in pts who had relapsed early. Methods: This was a retrospective analysis of 646 pts who received intravenous B, 1.3 mg/m2 on days 1,4,8 and 11 of every 21-day cycle ± PLD, 30 mg/m2 on day 4. Results: 359 pts had previously received transplant, 114 (32%) of whom relapsed within 12 months from SCT. The median age, gender distribution, time from diagnosis trial enrollment, measures of disease burden (M-Protein levels and B2M) and renal function were comparable between the early and late relapse groups. There was no difference in overall response rates [complete + partial response (CR+PR)] or very good PR (VGPR) rates between the two groups, or between treatment arms within each group. There was no significant difference in TTP between early vs. late relapse groups (HR=0.94). 12-month survival from randomization was significantly lower in the early relapse group as compared to late relapse (83% vs. 92% respectively, p=0.009). However, within the early relapse group 12-months post-randomization survival rate was significantly superior following treatment with PLD+B as compared to B alone [52/56 patients (93%) vs. 43/58 patients (74%) respectively, p=0.01]. Correspondingly, TTP was better in this group with PLD+B vs. B alone (276 days vs. 205 days respectively, p=0.13). Overall, the toxicity profiles of the combination and B alone were comparable regardless of early or late relapse following SCT. Conclusions: The present analysis of the MMY3001 study corroborates the prior Mayo observation of lower survival in MM pts relapsing within 12 months of SCT. Importantly, it demonstrates that PLD+B may provide a therapeutic advantage for high-risk MM pts with early relapse following SCT.

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 (&gt;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 Introduction: autologous stem cell transplantation is a potentially curative or may augment the time to progression in Multiple Myeloma (MM) patients. The immunotherapy with rituximab may help control the minimal residual disease after high dose chemotherapy. Twenty percent (20%) of Multiple Myeloma patients express the CD20+ protein and can be target for immunotherapy. Objective: The aim of this study was to evaluate the use of rituximab after autologous stem cell transplantation for Multiple Myeloma. Patients and Methods: eight patients (4 male) with a median age of 53 (range 43–59) years diagnosed with MM. All of them had received at least one previous regimen were enrolled in the protocol study. All patients signed the consent form. Patients in relapse received a salvage regimen with C-VAD n=2 (cyclofosfamide 4 g/m2 e vincristine 0.4 mg/d (d 1–4), doxorrubicin 0.9 mg/m2 (d1-4) e dexametasone 40 mg (d1-4; 9-12; 17–22) or cyclofosfamide (1OO mg/kg, n=7) followed by stem cell harvesting. The preparative regimen was Busulfan 12 mg/kg and cyclofosfamide 120 mg/kg or Melphalan 200mg/m2. Rituximab at a dose of 375mg/m2 weekly x 4 was given every 6 months for 2 years after SCT. The clinical characteristics of the patients are shown on Table 1. Results: the median time to ANC and platelets engraftment was 11 (range 8–12) and 26 (range 17–35) days. Patients have been in CR at a median time of 11 months follow-up. Minor Rituximab-associated toxicities were seen:rigor, fever and short of breath that were controlled with acetaminophen and diphenidramine. Conclusion: the Rituximab given after autologous stem cell transplantation is safe in Multiple Myeloma patients and may prolong time to disease progression. A randomized study is required to evaluate the role of rituximab after ASCT.

Abstract Abstract 2354 High-risk or advanced acute leukemias are associated with poor outcome even with the use of stem cell transplantation (SCT) with or without total body irradiation (TBI). Based on encouraging results with the use of clofarabine (CLO) for reinduction treatment of acute leukemias, we have developed a phase I/II protocol using this agent with melphalan (Mel) and thiotepa (Thio) followed by unmodified SCT for the treatment of patients (pts) with high-risk (HR) leukemias. To date, 28 consecutive pts were treated on, or as per protocol, with 26 pts evaluable for follow-up. There were 15 males and 11 females aged 1–58 years (median 5.3 years). Cytoreduction consisted of CLO at dose level I of 20 mg/m2/day × 5 days (n=23) or at dose level II of 30 mg/m2/day × 5 (n=3), Thio 10 mg/Kg/day × 1 day and Mel 70 mg/m2/day × 2 days. Graft-versus-host disease (GvHD) prophylaxis consisted of tacrolimus and mycophenolate mofetil (MMF), or tacrolimus and methotrexate. Twenty pts had acute lymphoblastic leukemia (ALL) in complete remission (CR1; n=5), CR2 (n=5), CR3 (n=9), or relapse (n=1). Five pts had acute myeloid leukemia (AML), in CR1 (n=1), CR2 (n=2), or CR3 (n=2). One pt had myelodysplastic syndrome (MDS) in RAEB. For the pts with ALL in CR1, very HR features included: Infant MLL (N=2), Philadelphia (Ph1) chromosome (N=2) and Induction failure (N=1). For the pts with ALL in CR2, HR features included: Infant MLL (N=1), 2nd SCT (N=1), Ph1 and 2nd SCT (N=2), while 1 pt had prior CNS infarcts precluding the use of TBI. The one pt with AML in CR1 had M7-AML. This was a first SCT for 14 pts, a 2nd SCT for 11 pts and 3rd SCT for 1 pt, with time from previous SCT to the present one being 5–73 months (median 11.3 mo) for those 12 pts. Donors were HLA-matched siblings (n=8), HLA matched unrelated donors (n=8), or HLA mismatched unrelated donors (N=10). Stem cell grafts were bone marrow (n=12), peripheral blood (n=7) or double cord blood (n=7) stem cells. Twenty four of the 26 evaluable pts engrafted, while 2 pts died prior to engraftment. Toxicity of the SCT cytoreduction included elevation of hepatic transaminases in 17 of 26 evaluable pts (AST elevation of 5–19 fold and ALT elevation of 7–16 fold), with a subsequent normalization in all pts. Mucositis was mostly at acceptable grade 1–2 levels. Two pts developed a syndrome of renal and hepatic insufficiency leading to hepatic veno-occlusive disease (VOD) (1 pt at each of the 2 dose levels). Non-relapse mortality included: VOD (N=2), infections (N=3), treatment related sarcoma, a malignancy secondary to the irradiation received with a prior transplant (N=1). With a follow-up of 3–57 mos (median 21 mos), 15 of the 26 pts are alive, disease-free. Five pts relapsed and 4 died subsequently of disease, while 6 pts died of non-relapse morality. Overall (OS) and disease-free survival (DFS) at 2 years were both 58%. DFS was 56% for pts > 18 years and 53% for pts < 18 years (p =0.36); it was 64% for recipients of a first HSCT and 41% (p=0.97) for recipients of a second or third HSCT. Five pts (4 recipients of unrelated donor SCT; 3 from mismatched donors) developed Grade 2–4 acute GvHD. Four of these pts went on to develop chronic GvHD. Immune reconstitution was rapid; for the evaluable pts, it included absolute CD4 counts > 200 cells/L at 1–3 mos for 15 pts and at 4–8 mos for 4 pts. This cytoreductive regimen represents a promising approach for the transplantation of patients with high risk acute leukemias. It was well tolerated for pts requiring a second SCT and is also associated with rapid immune recovery. Ultimately, a large scale study would need to be done to determine if this approach could offer equal or superior results to TBI containing regimens for ALL or AML. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 4554 High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is currently standard treatment for younger patients with multiple myeloma, resulting in improved survival and response rate compared to conventional chemotherapy. Disease relapse, however, remains almost inevitable and thus the role of two successive (tandem) autologous stem cell transplants has been evaluated in chemorefractory patients as a means of prolonging duration of disease response. We retrospectively analysed the results of nine patients with chemorefractory disease treated at a single UK institution who received tandem ASCT between January 1998 and February 2009. There were six men and three women. Median age at diagnosis was 56 years (range, 42–65 years). Paraprotein isotype was IgG in eight patients and IgA in one patient. Median serum paraprotein level was 41g/L (range 12–73g/L) at presentation. At time of 1st transplant six patients were in stable disease (SD) and three had evidence of progressive disease. Conditioning melphalan dose was 140mg/m2 in all but two patients who received 110mg/m2 and 200mg/m2. Median time between transplants was 3.7 months (range 2.3–6.4 months) with PR and SD being observed in 2/9 and 7/9 patients at time of 2nd transplant. None of the patients reached complete response (CR). One patient received melphalan 140mg/m2 prior to 2nd transplant. The remaining patients received melphalan 200mg/m2. Median follow up after tandem transplant was 54.3 months (range 15.6 –143.6 months). No treatment related mortality was reported. At the time of analysis, six patients were still alive and under follow up with an overall survival (OS) figure for the group of 52% at 10 years from diagnosis (Figure 1). Median progression free survival (PFS) was 20 months from 2nd transplant (range 6.7–62.6 months) (Figure 2). Tandem autologous stem cell transplant in chemorefractory patients has resulted in overall survival similar to autologous stem cell transplant in chemosensitive patients and should be considered in patients with chemorefractory disease.

Abstract Abstract 4548 High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is currently standard treatment for younger patients with multiple myeloma (MM). In the face of almost inevitable disease relapse, there is growing evidence for second ASCT as salvage therapy in certain patient groups. However, few published data exist regarding efficacy and safety of third ASCT in relapsed disease. We retrospectively analysed the results of eight patients treated at a single UK institution who each received three separate autologous stem cell transplants for relapsed MM between May 1997 and April 2012. There were four men and four women. Median age at diagnosis was 48 years (range, 25–64 years). Paraprotein isotype was IgA in two patients and IgG in the remaining six patients. At the time of 1st transplant, seven patients were in partial response (PR) and one in complete response (CR). Conditioning melphalan dose was 200mg/m2 in all but two patients who received 140mg/m2. Three patients entered CR following 1st transplant and four patients showed PR. Median time to disease progression was 31 months (range, 11.8–52.9 months). Prior to 2nd transplant, five patients achieved very good partial response (VGPR) and three PR with induction chemotherapy. Melphalan dose was 200mg/m2 in five patients and 140mg/m2 in the remaining three. Median time to disease progression was 22.3 months (range, 10.1– 39.6 months). At the time of 3rd transplant, two patients had achieved VGPR following induction chemotherapy, one showed PR, two stable disease (SD) and three evidence of disease progression. For the 3rd transplant, melphalan dose was reduced in most cases. Median follow up post 3rd transplant was 8.3 months (range 1.1–29.3 months). One patient died of overwhelming sepsis within one month of transplantation (treatment related mortality). At the time of analysis, five patients had relapsed following 3rd ASCT, with median time to disease progression of 10.4 months (range, 2.7–23.7 months). Three of these patients died at 3.5, 17.6 and 27.1 months post 3rd transplant. The remaining two patients are alive with no evidence of disease relapse (progression free survival (PFS) time of 3.3 and 1.3 months). Overall survival (OS) for the group from diagnosis is 62% at 10 years with a median OS from diagnosis of 149 months (range 68.5 – 189.2 months) (Figure 1). Median OS for the group from 3rd transplant is 17.6 months (range, 1.1–29.3 months) (Figure 2). Median PFS is 10.4 months (range 1.1–23.7 months). These results demonstrate that third ASCT is a possible treatment strategy for patients with relapsed MM and may prolong patient survival.

Abstract Introduction The prognosis of patients with multiple myeloma (MM) has improved in the last years due to the important advances in the knowledge of the biology of the disease, the implementation of new drugs and the incorporation of autologous hematopoietic stem cell transplant (autoHSCT). The allogenic hematopoietic stem cell transplant (alloHSCT) continues to be controversial: it offers a curative potential but with the cost of high toxicity, limiting the procedure to those young patients with a high-risk disease. This procedure shall be performed in expert centers and, whenever possible, in the context of a clinical trial. In the following we describe the experience of our center with alloHSCT in advance multiple myeloma patients. Patients and methods A total of 18 patients were diagnosed with multiple myeloma received an alloHSCT during a 13 year period (1996-2013), with a median age of 46 ± 5.9 years. All of our patients received an allogenic HLA matched sibling donor with reduced-intensity conditioning. The majority of patients were transplanted because of advanced disease, relapse after an autologous transplant or as part of a sequential transplant in patient with a high risk disease. One patient received, in two occasions, an alloHSCT. Around 70% of patients had received more than 3 previous lines of treatment including, in nearly 95%, an autoHSCT.

Global TRM was 16.6% (3 cases). The incidence of acute graft versus host disease (aGVHD) was 22%, controlled on most cases when corticosteroids were initiated. More than half of the patients developed chronic graft versus host disease (cGVHD), with an equal distribution on either presentation as limited or extensive. (Table 2) The total number of patients eligible for analysis was 17 (one patient was lost on follow-up). With a median follow up of 11 years, the overall survival (OS) was of 8.06 years [IC 95% 4,33-11,78] (figure 1.) and the estimated progression free survival (PFS) was of 25.83 months [IC 95% 8.87-42.79](figure 2). A total of 5 (29,4%) patients are still alive and 2 (11,7%) of them are in complete remission, of these 1 patient did not have a previous autoHSCT with a follow up of almost 15 years. Conclusions: Our results are similar to those reflected on the literature1-2. However we have to point out that our population is homogenous with advanced MM with more than 3 previous lines of treatment including in most cases auto-HSCT. In spite of this, morbility and mortality in our cohort was acceptable with the limitation of a high rate of cGVHD. There is a need of more studies including more patients to evaluate the role of alloHSCT in the era of new drugs for MM. References 1. Rosi-ol L et al.

8589 Background: Denosumab (dmab) is a fully human monoclonal antibody against RANKL and is superior to ZA in preventing skeletal-related events (SREs) as shown in 3 identically designed phase 3 trials (N=5723). Overall survival (OS) was balanced between treatment groups in the overall study populations of these trials. In the trial of patients (pts) with solid tumors (excluding breast and prostate) and multiple myeloma (MM), OS was longer for dmab pts with lung cancer, shorter for pts with MM, and balanced for pts with other solid tumors. This analysis further characterizes the results from the MM subset of this trial. Methods: Pts with solid tumors or MM were randomized (1:1) to receive 120 mg of SC dmab or 4 mg of IV ZA Q4W. Daily calcium and vit D supplements were strongly recommended. The primary endpoint was the time to first on-study SRE; results from the primary endpoint and lung cancer subset were previously reported. Results: Of 1776 randomized pts, 10% had MM (93 ZA, 87 dmab). OS favored ZA (hazard ratio: 2.26; 10 subject difference in deaths). 1-year OS was 83% dmab, 97% ZA. Imbalances in baseline prognostic characteristics were observed. More pts in the dmab arm had low baseline renal function (CrCl < 40 mL/min) (ZA 2 [2%], dmab 9 [10%]) and more ZA pts underwent stem cell transplant (ZA 23 [25%], dmab 15 [17%]). Additionally, more ZA pts had stage I tumors at diagnosis (ZA 13 [14%], dmab 9 [10%]) and better performance status (ECOG = 0; ZA 30 [32%], dmab 21 [24%]). Study discontinuations due to consent withdrawal or lost to follow-up were also higher in the ZA group (ZA 17 [18%], dmab 11 [13%]) and occurred earlier in the ZA arm (ZA 59%, dmab 45% within 9 months of randomization). Conclusions: In this SRE study of dmab vs ZA, pts were stratified by baseline characteristics known to affect SRE outcomes, but not by prognostic factors or concurrent anticancer therapy that may impact survival in MM. OS results in the MM cohort are difficult to interpret due to small sample size and imbalances in baseline disease characteristics, stem cell transplant therapy, and consent withdrawal or loss of follow-up that favored ZA. A phase 3 trial is currently underway, which controls for these factors in pts with MM. Clinical trial information: NCT00330759.

Abstract Introduction Progressive multifocal leukoencephalopathy (PML), caused by the John Cunningham (JC) virus, is an infection that requires immunosuppression for its manifestations and is fatal disease in many cases. (1) After asymptomatic primary infection, which occurs in childhood, the virus remains quiescent. (1,4) The classical clinical presentation is that of a subacute symptomatology that develops over weeks or months and consists of diverse sensorimotor abnormalities depending on the site of brain involvement. Approximately 22 cases of PML amongst patients with multiple myeloma (MM) have been reported in the literature between 1965 and April 2020. (5) Methods We performed a retrospective chart review of all myeloma patients who were treated at the Princess Margaret Cancer Center from 2010-2020 to identify cases of PML. Patient and disease characteristics, responses, and survival outcomes were collected from Myeloma and Stem Cell Transplant databases and electronic patient records under REB approval. Results We identified 3 cases of PML in MM patients at our center over the past 10 years, all of which occurred in patients receiving therapy containing an immunomodulatory derivative (IMID), i.e., thalidomide, lenalidomide or pomalidomide. Patient 1 A 52-year-old male with kappa light chain MM presented in 2009 on hemodialysis and received upfront bortezomib and dexamethasone followed by melphalan 200mg/m 2 and autologous stem cell transplantation (ASCT) in March 2010; maintenance with thalidomide was given until July 2011 when he presented to the ER with left-sided weakness, facial droop, and decreased strength. CT scan showed right-sided hypodensity in keeping with demyelination. PML was confirmed by MRI, lumbar puncture with positive PCR for JC virus, and a brain biopsy (Fig 1 A-C). He was treated with mirtazapine, and also developed status epilepticus controlled with phenytoin and phenobarbital. His myeloma treatment was never resumed after the diagnosis of PML due to concerns about viral reactivation. Approximately 3 years after PML diagnosis, his serum free kappa protein levels started to increase; he remained on hemodialysis but experienced no new myeloma-related organ damage and no myeloma treatment was offered. His last follow-up in clinic was in March 2019. However, he succumbed to S. pneumonia septicemia in July 2019. Case 2 A 68-year-old female with IgG kappa MM diagnosed in 2004 was treated with high-dose dexamethasone induction followed by melphalan 200mg/m 2 and ASCT and relapsed 2 years later. She commenced cyclophosphamide and prednisone until July 2011 when treatment was changed to lenalidomide and prednisone; subsequent progression in February 2014 was treated with pomalidomide/bortezomib/prednisone. In November 2014, we noticed worsening vision. Brain MRI showed hyperintensity in T2 in the occipital lobe. Her myeloma treatment was stopped and she received corticosteroids with no improvement. LP in January 2015 was positive for JC virus and the diagnosis of PML was made. She was managed with supportive measures. Her last clinic follow-up was in 2015 and the patient died from progression in September 2015. Case 3 A 52-year-old male with IgA lambda MM diagnosed in 2015 was treated with CYBOR-D induction followed by melphalan 200mg/m 2 and ASCT. He initially received lenalidomide maintenance which was changed to bortezomib due to toxicity. On progression in January of 2019 he was placed on a clinical trial of the anti-BCMA antibody drug conjugate belantamab mafodotin in combination with pomalidomide and dexamethasone on which he achieved a VGPR. In October 2020, he developed confusion and memory problems, as well as involuntary twitching. A brain MRI showed possible demyelination Two LPs were negative for JC virus, but a targeted brain biopsy confirmed the diagnosis of PML (Fig 1 D-F). His myeloma treatment was discontinued, and he was started on mirtazapine. At his most recent clinic visit in May 2021 his speech, memory and functional status had improved considerably and there were no signs of myeloma progression. Conclusion Our current series of PML in MM showcases the potential contribution of IMIDs and other novel agents--such as the newer monoclonal antibodies like belantamab mafotidin-- to the reactivation of JC virus and subsequent PML. Our series also demonstrates that neurologic improvement and longer survival can be observed with earlier management. Figure 1 Figure 1.
