Historically, high-dose therapy in combination with autologous stem cell transplants (ASCT) for multiple myeloma (MM) was reserved for younger patients. In more recent years, the use of ASCT has expanded in the older population. However, there is still limited data on the utilization and efficacy of ASCT in older patients, particularly those over the age of 75. To further evaluate this issue, we retrospectively analyzed all patients with newly diagnosed MM between the ages of 75-78, the institutional cutoff for ASCT eligibility, that were referred to the stem cell transplant unit at our institution for consultation from the years 2012-2018. Baseline characteristics, anti-myeloma treatments, and patient outcomes were abstracted through chart review. Seventy-five patients were referred to our institution. 71% were male, 29% female. 39% patients were considered ineligible for ASCT by the consulting transplant physician. Most patients were considered transplant ineligible due to comorbidities or poor performance status. Of the 46 patients eligible for ASCT, 52% underwent the procedure during their first-line therapy. The majority of those patients received reduced intensity melphalan (140 mg/m2) while 2 patients received conventional dosing (200 mg/m2). The other 22 patients eligible for ASCT declined or elected to defer the procedure and to be treated with conventional therapy. The characteristics of these three groups were similar and are detailed in Table 1. After a median follow-up of 30 months, 25% of the patients had expired. Estimated median overall survival (OS) was 71.3 months (unable to quantitate 95% CI) for all patients. Compared to transplant eligible patients, regardless of transplant receipt, those who were transplant ineligible had a 186% increase risk for death (HR 2.86; 95% CI 1.12-7.35; p = 0.029). There was also a notable trend for longer OS in those who underwent ASCT compared to those who were eligible but declined the procedure, but it was not statistically significant (HR 0.36; 95% CI 0.10-1.28; p = 0.114). At a transplant center, two-thirds of patients referred for newly diagnosed MM between the ages 75-78 were considered eligible for ASCT and one-third underwent the procedure. Outcomes were better for patients eligible for ASCT, regardless of whether they underwent the procedure. There was also a trend for better OS in patients who underwent the procedure compared to those who declined. While small sample sizes and the retrospective nature of the study limit our ability to draw conclusions, it appears that ASCT has an OS benefit among patients age 75-78.

Abstract Abstract 837 Background: Combination therapy with cytotoxic chemotherapy and tyrosine kinase inhibitors has improved the outcome for patients with Ph+ ALL with durable remissions in some patients even without an allogeneic stem cell transplant. The dual Src and Abl inhibitor dasatinib has ∼325 times more potent in vitro kinase inhibition than imatinib against BCR-ABL with significant clinical activity in patients with imatinib-resistant lymphoid blast phase CML (CML-LB) and Ph+ ALL. Aim: To determine the efficacy and safety of combining chemotherapy with dasatinib for treating patients with Ph+ ALL. Methods: In this phase II trial, patients with newly diagnosed Ph+ ALL receive dasatinib 50 mg po bid (or 100 mg daily) for the first 14 days of each of 8 cycles of alternating hyperCVAD and high dose cytarabine and methotrexate. Patients in CR continue to receive maintenance dasatinib 50 mg po bid (or 100 mg daily) and vincristine and prednisone monthly for 2 years followed by dasatinib indefinitely. Results: We have enrolled in the study 34 patients with untreated Ph+ ALL and 7 patients with 1 prior cycle of chemotherapy (before Ph+/BCR-ABL+ status was known). Patients younger than 50 years old have received a median of 6 cycles (range 2-8) and patients 50 years and older have received a median of 6 cycles (range 1-8). 20 patients are receiving maintenance in CR and two have completed the entire treatment regimen. Median age is 51 years (range 21 – 79); 22 patients were older than 50 years, Median WBC at diagnosis was 13.6 × 109/L (range, 1-276 × 109/L). 12 patients had CNS involvement at presentation. All patients are evaluable for assessment of response to induction; 39 (95%) achieved CR after first cycle or were CR at start. Two patients died before response assessment from infections. Thirty-one of 39 (79%) evaluable patients achieved cytogenetic (CG) CR after 1 cycle; 4 had a major CG response (3 had 5% and one had 15% Ph+), 2 had insufficient metaphases, and 2 are unknown (no CG exam on day 21 marrow). To date, 22 patients (56%) have achieved complete molecular remission (CMR) and another 8 (21%) have achieved a major (but not complete) molecular response (MMR) at a median of 14 weeks from initiation of treatment (range 2 – 59 weeks). Minimal residual disease assessment by flow cytometry is negative in 35 (90%) patients at a median of 3 weeks (range, 2-18 weeks). The median time to neutrophil and platelet recovery for cycle 1 is 18 and 23 days and for subsequent cycles is 15 and 20 days. Grade 3 and 4 adverse events have included bleeding (GI, GU, soft tissue and subdural hematomas)(18), pleural effusions (9), pericardial effusion (1), reversible rise in creatinine (10), deep vein thromboses (6), pulmonary emboli (3), as well as diarrhea, infections, hypophosphatemia, hypokalemia, hypocalcemia, hyperglycemia, and elevated transaminases. With a median follow up of 13 months (range 1-33), 29 patients (71%) are alive and 27 (66%) are in CR; 4 patients died in CR; 1 from an unrelated cardiac event and 3 from infections. Three patients have undergone an allogeneic stem cell transplant. The median disease free survival is 48+ weeks (range,1 to 140+) and the median overall survival is 52+ weeks (range, 3 to 143+). Eight patients have relapsed with a median response duration of 51 weeks (range 23-73) and 6 of them have died. In 5 patients morphological relapse was preceded by flow and molecular relapse. Five relapsed patients had ABL mutations (3 T315I, 1 F359V, and 1 V299L). Conclusion: Combination of chemotherapy with dasatinib is effective in achieving long term remissions in patients with newly diagnosed Ph+ ALL.

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.

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 Background: Carfilzomib is an epoxy ketone, second generation proteasome inhibitor approved for the treatment of relapsed and refractory multiple myeloma. It has shown very high activity when combined with lenalidomide and dexamethasone for the treatment of newly diagnosed patients with multiple myeloma. This is the first reported trial of carfilzomib, cyclophosphamide, and dexamethasone (CCyD) in newly-diagnosed, transplant eligible patients. Methods: This study was a multi-center Phase Ib, open-label, dose-finding study in newly diagnosed transplant eligible multiple myeloma patients (pts) studying the combination of CCyD as induction therapy prior to autologous stem cell transplant (ASCT). Pts could receive a minimum of 4 cycles and up to 6 cycles prior to ASCT. Pts were enrolled into a dose-escalation treatment cohort. A standard 3+3 dose escalation schedule was used with cohorts of carfilzomib 36 (initial), 45 and 56 mg/m2 (administered over 30 minutes on days 1, 2, 8, 9, 15 and 16) combined with 300 mg/m2 of oral cyclophosphamide weekly on days 1, 8, 15 and 40 mg of oral dexamethasone once weekly. Adverse events (AEs) were graded by NCI-CTCAE v4. Response was assessed by the IMWG criteria. Prior therapy was limited to up to 160 mg of dexamethasone or limited field radiation. Results: 28 patients were enrolled from 5 centers. Of 28 patients enrolled, 3 did not complete 4 cycles of therapy (1 proceeded to ASCT after Cycle 3) and are not evaluable for response (pts came off secondary to AE of pulmonary HTN unrelated, secondary to SAE of CHF possibly related, due to PI discretion related to maximum benefit achieved), 8 patients did not undergo ASCT (1 had PD after Cycle 5), 8 patients proceeded to ASCT (1 the aforementioned patient after Cycle 3), 6 patients have completed induction and are still pre-transplant and 4 patients are still on treatment. The median age was 64 years (range 44–74), 57% were male. Cytogenetic abnormalities included 13 patients with del(13), 4 with del(17p), 2 with t(14;16) and 1 with hypodiploidy for a total of 16 patients with high-risk cytogenetics. In the dose-escalation portion of the study, the maximum administered dose tested was 56 mg/m2 carfilzomib. There was one DLT in cycle 1, of Grade 3 dyspnea, at the 56 mg/m2 level. Drug-related AEs occurring in >20% of patients included fatigue (23%) and thrombocytopenia (31%). Thirty-one percent experienced at least one Grade ≥3 AE with dyspnea and nausea as the most common. There were no deaths on study with a median follow-up of 4.9m (range: 1.1 to 13.1m). One pt came off study after Cycle 5 for PD as evidenced by new plasmacytomas. Six patients received 36-45 mg/m2 carfilzomib on the dose escalation portion of this study and 22 patients received the maximum administered dose of carfilzomib at 56 mg/m2. One patient yet to be enrolled to obtain 20 efficacy evaluable pts at the maximum dose. Twenty-three patients were response evaluable. Median of 5.7 cycles of therapy with 2 CR, 9 VGPR, 10 PR, 1 MR and 1 PD for ≥ PR rate of 91%. Of the 12 response-evaluable patients with high risk cytogenetics, 92% were ≥ PR; of the 11 standard risk patients, 91% were ≥ PR. Of 9 patients who underwent stem cell mobilization, all collected adequate stem cells and median number of stem cells collected was 12.58 (5.07-25.31) x106 CD34+ cells/kg. Conclusions: The combination of CCyD given to untreated, symptomatic patients with myeloma was well tolerated and highly active with an 87% RR and a 48% ≥ VGPR after 4 to 6 cycles. This study compares favorably with other regimens used for induction prior to transplant for the management of newly diagnosed multiple myeloma.

Abstract Abstract 4060 Introduction: Rajkumar et al. reported improved survival with lenalidomide and low dose dexamethasome as compared with lenalidomide and high dose dexamethasone (Rajkumar V, Lancet Oncol 2010). In addition, we reported promising outcomes of a retrospective cohort of newly diagnosed multiple myeloma patients treated with single agent lenalidomide(Baz R Leuk Lymphoma. 2010). Accordingly, we conducted this prospective single center open label study to evaluate the efficacy of a response adapted approach using single agent lenalidomide in older adults with newly diagnosed standard risk multiple myeloma. Patients/Methods: Eligible patients had symptomatic multiple myeloma without high risk features (b2microglobulin (b2m) ≤5.5, absence of t(4;14), t(14;16), 17p deletion, aneuploidy or 13q by metaphase cytogenetics) and were not eligible or not willing to receive high-dose therapy and stem cell transplant. Patients received lenalidomide 25 mg PO D1–21 every 28 days for 2 cycles. If patients had a minimal response or better (MR, 25% reduction in serum M spike) after 2 cycles, they continued on single agent lenalidomide until progressive disease. If patients had stable disease after 2 cycles, prednisone 100 mg PO D1–5 was added to their lenalidomide. In the event of progressive disease on single agent lenalidomide or on lenalidomide/prednisone, therapy was changed to lenalidomide (at the tolerated dose) and dexamethasone 40 mg PO weekly. Thromboprophylaxis was with aspirin, warfarin or low molecular weight heparin. Responses were per IMWG response criteria. The study was approved by the institutional review board. Results: Between February 2010 and May 2012, 22 patients were screened and 19 were eligible. The median age was 75 years (range 65–83) and 12 were males. Per protocol, no patient had ISS stage 3 disease but 8 patients had ISS stage 2 and 11 stage 1 (median b2m was 3.2 mg/L (range 2.2–5.5)). 5 patients had 13q deletion by FISH alone, 4 had t(11;14), another 3 had trisomy 11, and 2 had trisomy or tetrasomy 1q. The median baseline creatinine clearance was 66.5 ml/min (range 43–109). After 2 cycles of single agent lenalidomide, 9 patients (47%) had a PR (partial response), 6 (32%) MR, 3 (16%) stable disease (SD), and 1 (5%) progressive disease. The best response to single agent lenalidomide was as follows: 3 had a stringent complete response sCR (16%), 1 (5%) a very good partial remission (VGPR), 8 PR (42%), 4 MR (21%), 2 SD (11%) and 1 PD (5%). The estimated 1 year PFS to single agent lenalidomide is 80%. Five patients required the addition of dexamethasone with the following responses: 1 VGPR, 1 PR, 1 MR, 1 SD and 1 PD; Three patients required the addition of prednisone and the response to lenalidomide prednisone was 1PR, 1 MR, 1 SD. Five patients went off study, 2 for PD and 3 withdrew consent (2 were in PR at the time and 1 in SD). The estimated 1 year PFS for the protocol therapy is estimated at 94%. Eleven patients had dose reduction in lenalidomide; 5 patients to 15mg and 6 patients to 10 mg. Grade 3/4 neutropenia, thrombocytopenia, anemia, febrile neutropenia and fatigue occurred in 58%, 5%, 10%, 5% and 5% of patients respectively. Conclusion: In this patient population, single agent lenalidomide results in an ORR (PR and better) of 63% and clinical benefit rate (MR and better) of 84% with only a quarter of patients requiring the addition of dexamethasone. A response adapted therapy using single agent lenalidomide is safe and effective in older adults with standard risk myeloma sparing dexamethasone toxicities from the majority of patients. Updated results for ongoing accrual of up to 30 evaluable patients will be presented at the meeting. Disclosures: Baz: Celgene, Millennium, Bristol Myers Squibb, Novartis: Research Funding.

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 Background We hypothesized lenalidomide (len) related diarrhea (LRD) may correlate with activation of an immune response against multiple myeloma (MM) based on colon biopsies that showed crypt apoptosis reminiscent of GVHD in 3 MM patients with severe LRD but without prior allogeneic stem cell transplantation or gastrointestinal disorder. To investigate whether survival may be influenced by the presence of LRD we performed a retrospective chart review. Methods Patients who developed symptomatic MM on or after 1/1/2005 as defined by the start of anti-MM therapy and had been on len for at least 6 consecutive months by 12/31/2010 were included in the analysis. Significant LRD was considered present if the treating physician attributed the diarrhea to len and recommended supportive therapy in at least two clinic notes.  The first time treatment for LRD was recommended was used as the date of onset of LRD. As possible confounding factors age at the start of len therapy, number of prior regimens, prior high dose chemotherapy with autologous stem cell transplant (ASCT), and use of antineoplastic agents other than corticosteroids at any time during the continuous len therapy were collected. The primary outcome was overall survival (OS), which was calculated from the start of len. Fisher’s exact test, Mann-Whitney test, and the logrank test were used to compare characteristics and duration of len between patients with and without LRD. Proportional hazards models were used to assess the impact of LRD on OS. The lag between the start of len and development of LRD was accounted for by treating LRD as a time-varying covariate in these models. Results 161 patients were identified, 47 (29%) had LRD, and 59 (37%) died during follow up. LRD and no LRD groups were balanced for gender, age, number of prior regimens, prior transplant, and use of antineoplastic agents other than corticosteroids with len, but len treatment duration differed; LRD patients had received a median of  43.4 consecutive months of len (range 5.8-82.9) compared to 14.6 (range 5.9-89) for patients without LRD (p=0.001). Onset of LRD occurred after a median of 17.7 months (range 0.3-75.4) of len therapy. In multivariable analyses, development of LRD (HR 0.46, 95% C.I. 0.21-1.00, p=0.05) was associated with improved OS as were the number of prior therapies (0-2, vs >2, HR 0.16, 95% C.I. 0.08-0.32, p<0.0001) and no use of antineoplastic therapy other than corticosteroids during len therapy (HR 0.52, 95% C.I. 0.29-0.93, p=0.03), while age and prior ASCT (p=0.52 and 0.49, respectively) were not. Conclusion Late onset of lenalidomide related diarrhea (LRD) is compatible with an immune mediated effect that may signal anti-MM immune activity since LRD requiring supportive measures correlated with survival in MM in analyses that adjusted for lag time. While more study is needed to prove this hypothesis, our findings suggest that diarrhea on len may argue for continued therapy rather than discontinuation.

Critical Determinant

Abstract Background: The depth and durability of hematologic response is a critical determinant of outcome in patients (pts) with light chain (AL) amyloidosis. Complete hematologic remissions (CR) following risk-adapted melphalan and stem cell transplant (RA-SCT) in pts with AL amyloidosis is associated with organ improvement and extended overall survival (OS). We have previously shown that using bortezomib and dexamethasone (BD) as consolidation following RA-SCT is associated with deeper hematologic responses and favorable outcomes. We have conducted a prospective phase II trial using BD as induction followed by RA-SCT and BD consolidation to determine the safety and hematologic and organ response rates of this treatment program for newly diagnosed, transplant-eligible pts with AL amyloidosis. Methods: Untreated pts with AL amyloidosis received 1-3 cycles of BD (B 1.3mg/m2, IV/SC, and D 40mg, IV/PO, days 1, 4, 8, 11). BD was discontinued before 3 cycles in patients who achieved CR. Pts were then assigned melphalan 100, 140 or 200mg/m2 based on age, renal function and cardiac involvement; Starting 3 months following RA-SCT, pts received six cycles of BD (B 1.3mg/m2, IV/SC and D 20mg, IV/PO days 1, 8, 15, 22) every 12 weeks as consolidation. Hematologic responses were assessed using International Society of Amyloidosis criteria (Palladini et al. JCO 2012) and organ responses using updated criteria (Palladini et al. Blood 2014), after induction, 3 months post RA-SCT, and at 12 and 24 months from treatment initiation. Patients with New York Heart Association Class III/IV heart failure, ECOG > 2 or > grade 2 neuropathy were ineligible. Results: Twenty pts, 70% male, with a median age of 60.1 years with renal (55%), cardiac (65%), liver/GI (15%) or nervous system (15%) involvement received BD induction and 18 patients have been transplanted. Two pts with cardiac disease died during BD induction (10% TRM); 85% of pts are alive with a median follow up of 28 mo. By intent to treat, 60% and 70% of patients achieved at least a very good partial response (>VGPR) following BD induction and RA-SCT, respectively. Overall, 95% of patients achieved hematologic responses (>PR) including 35% CR. Cardiac and renal responses were seen in 75% (N=8) and 60% (N=10) of evaluable pts at 1 year following treatment initiation. Most common grade >3 adverse events included GI (40%), Renal (30%), infectious (10%), and cardiovascular (10%); Grade 2 or higher neuropathy was seen in 40% of pts and warranted discontinuation of BD consolidation in 35% of pts. Conclusion: In newly diagnosed AL amyloidosis pts, BD induction followed by RA-SCT was safe and rapidly and effectively induced responses resulting in organ improvement. There was 10% TRM during BD induction and no deaths during transplant supporting the notion that early mortality in newly diagnosed AL pts is independent of treatment received. The high incidence of neuropathy may be related to the administration of BD on a twice weekly schedule and rendered some pts ineligible for post-transplant therapy. Whether transplant-eligible pts will ultimately derive more benefit from proteasome inhibitor induction versus consolidation is worthy of further study.
