Description: 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

Description: Background Information is limited on the efficacy and long-term tolerability of weekly ubcutaneous (SC) bortezomib (BTZ), especially when given alone or combined only with glucocorticoids. We implemented use of SC BTZ in 12/2010 and based on equal AUC and efficacy with twice a week SC as IV BTZ (Moreau et al. Lancet Oncology 2011) at reduced but still significant neurotoxicity allowed weekly SC, maintaining the BTZ starting dose at 1.3mg/m2. Methods Multiple myeloma (MM) and AL amyloidosis (ALA) patients (pts) who had received SC BTZ by February 2013 were identified from our plasma cell disorder registry. After IRB approval, their electronic medical records were reviewed for occurrence, severity, and evolution of PNP with each BTZ containing regimen, administration schedule of BTZ, presence of underlying PNP and neuropathy risk factors (diabetes mellitus, ESRD, spinal cord compression/disease, vitamin B12 deficiency, alcoholism, chronic liver disease, hyperlipidemia, hypothyroidism), concurrently used antineoplastic agents, physician assigned responses, and reasons for BTZ dose reductions or discontinuation. To compare first BTZ regimen administration schedules Fisher’s exact test and chi-square tests were used for categorical data, Kruskal-Wallis and Wilcoxon rank sum test for age and interval from diagnosis to treatment, and logrank test for treatment duration. Proportional hazards models were used to assess the impact of BTZ administration schedule on neuropathy and response. The impact of prior regimens before first BTZ administration on response was estimated by logistic regression models. Results 136 patients were identified, 12 were excluded due to insufficient data (not followed at our Center). The remaining 124 pts began their first BTZ regimen between 02/2005 and 02/2013. 81% had MM, 12 % ALA, and 7% both MM and amyloidosis. Patients received a median of 2 BTZ containing regimens (range 1-9); overall 312 BTZ regimens were analyzed. In 114 SC weekly, 32 SC twice a week, 59 IV weekly, 62 IV twice a week, and 11 twice a week SC/IV followed by weekly BTZ regimens, neuropathy led to BTZ discontinuation in 7.9% (n=9), 9.4% (n=3), 13.6% (n=8), 22.6% (n=14), 9.1% (n=1), respectively, and to dose reduction in 5.3% (n=6), 3.2% (n=1), 6.8% (n=4), 6.5% (n=4), 9.1% (n=1), respectively. Patients who received weekly SC BTZ as their first BTZ containing regimen (n=37) had received a median of 0 prior regimens (range 0-10), 27% (n=10) had mild (n=8) or severe (n=2) underlying neuropathy, and most (68%) received BTZ with only glucocorticoids (n=23) or alone (n=2), while lenalidomide (n=8) or other agents (n=4) were added to 32%. After a median treatment duration of 4.3 months (0.2-23.3+), 26 of these 37 pts (70%) developed no neuropathy (n=20) or no worsening of pre-existing neuropathy (n=6), but 7 (19%) required BTZ dose reduction (n=2) or supportive medications (n=5) for neuropathy and in 4 (11%) BTZ was discontinued because of neuropathy. In multivariable analyses for neurotoxicity and lack of response, use of schedules other than weekly SC as the first BTZ administration schedule caused more neuropathy (HR 2.3, 95% C.I. 1.0-5.3, p=0.05), while age and underlying disease associated with neuropathy had no impact (p=0.57 and 0.61, respectively); lack of response tended to be more common with schedules other than weekly SC (HR 2.0, 95% C.I. 0.9-4.5, p=0.09) but age and disease (MM vs. AL amyloid) did not affect response (p=0.33 and 0.32, respectively). A response rate of 71% (n=22) to the first SC weekly bortezomib containing regimen in 37 pts who had received a median of 0 (range 0-10) previous regimens was within the expected range for standard administration schedules; of 8 pts who received weekly SC BTZ with not more than a total of 40mg dexamethasone per week as upfront therapy for myeloma, 5 achieved VGPR, 1 PR, and one MR; in 6 evaluable AL amyloid patients this upfront treatment led to VGPR in 3 and PR in 1 patient. Conclusions Weekly SC BTZ, even if administered only with glucocorticoids, is effective and better tolerated than other BTZ administration schedules. However, neuropathy continues to impact therapy, affecting about a third of patients in our series who received BTZ for the first time. Disclosures: Off Label Use: Upfront weekly SC bortezomib.

Description: Introduction The association between malignancy and venous thromboembolism (VTE) is well established. Less is known about the independent impact of VTE, both symptomatic and incidental, on survival in patients with prostate cancer. Methods We conducted a retrospective cohort study of 457 consecutive patients with prostate cancer who received outpatient clinical care at the Cleveland Clinic from January 2006 to June 2006. Data were collected regarding clinical characteristics, treatment and outcomes. Fisher exact (for categorical variables) and t-test (continuous variables) were utilized to test associations with VTE and mortality. Survival functions were estimated using the Kaplan Meier method and a Cox regression model was used to model the mortality hazard ratio (HR) with date of diagnosis as time origin. Results The mean age of our cohort of patients was 65.86 ± 8.64 years. Three hundred and fifty eight (78.3%) had clinically localized disease, 76 (16.7%) had locally advanced disease and 41 (8.9%) had metastatic cancer at diagnosis. One hundred twenty four (27.1%) men underwent surgery, 315 (68.9%) received radiotherapy, 201 (44%) received hormonal therapy and 71 (15.5%) received chemotherapy. Complete follow up was available on 403 patients of which 109 (27%) died during the period of follow up. VTE occurred in 42 (9.2%) patients (33 deep vein thrombosis, 5 pulmonary embolism, and 4 patients with both DVT and PE), of which 27 (64.3%) were symptomatic and 15 (35.7%) were incidentally diagnosed. Twenty-three were outpatients and 17 were hospitalized when VTE was diagnosed. Metastatic disease (p

Description: Background: Serum free light chains (sFLC) and immunofixation (IFE) analysis are used to detect monoclonal proteins. We noticed that some multiple myeloma (MM) patients (pts) had negative IFE results despite very high sFLC levels. This analysis was done to determine the frequency of this finding in a large cohort. Methods: Following IRB approval, samples with simultaneous sIFE and sFLCs ordered from 1/2013 to 9/2013 were identified by querying our lab electronic database. Freelite (R) Human Kappa & Lambda Free kit (The Binding Site, Birmingham, UK) was used for sFLC and SPIFE® ImmunoFix-15 gels (Helena Laboratories, Beaumont, TX) for IFE. Clinical review was performed for a subset of patients with discrepant results between the two assays. Results: 4404 samples from 2200 pts were identified with simultaneous sFLC and sIFE results. Overall 348 of 4404 (7.9%) samples had an abnormal sFLC ratio but a negative sIFE. Of 205 pts (457 samples) with involved serum free kappa above the expected IFE threshold (200 mg/L), 42 pts (103 samples) had negative sIFEs (20.5% pts; 22.5% samples) despite median free kappa of 556.6 mg/L (range 208.1 to 4954.4). This was much less common for involved free lambda. Only 4 of 107 pts with free lambda above 200mg/L had negative sIFEs (3.7%). Information of the nature of the plasma cell disorder was available on 40 of the 42 patients with free kappa 〉 200mg/L and negative IFE. In this group, 62.5% (n=25) had symptomatic MM, 12.5% (n=5) had asymptomatic MM, 5% (n=2) had light chain amyloidosis, 5% (n=2) had both amyloidosis and MM, and 15% (n=6) had MGUS or a not yet fully worked up plasma cell disorder. Conclusions: Serum IFE, with a commonly used kit, missed about 20% of patients with free kappa above the expected IFE threshold, while free lambda was detected more reliably. Results suggest current criteria for complete remission which rely on immunofixation and bone marrow plasma cell infiltration may need to be revised for kappa light chain myeloma.

Description: Background: While achieving complete remission (CR) is a major treatment milestone in acute myeloid leukemia (AML) patients (pts) undergoing induction chemotherapy (IC), it is the time to achieve CR (Tc) that has greater prognostic value in predicting subsequent survival. We are particularly interested in seeing whether trends in white blood cell (WBC) count elimination and recovery during induction phase can aid in prediction of Tc, thus enabling real-time prognostication. Methods: Adult pts diagnosed with AML (excluding acute promyelocytic leukemia) at the Cleveland Clinic from 10/08 - 11/12 who underwent IC with 7+3 (cytarabine and anthracycline) and achieved CR were included. Pretreatment variables including age, gender, race, smoking status, body mass index at dx, peripheral blood counts at diagnosis (dx), peripheral and marrow blasts at dx, disease classification and metaphase cytogenetics (per CALGB/Alliance 8461 criteria) were assessed. For mapping WBC elimination and recovery kinetics, we collected data on total WBC, absolute neutrophil count (ANC) and absolute lymphocyte count (ALC) at several different time points after IC – day 1, day 7, day 14 (range, 13-17), day 21, day 35 (range 30-45) and the day CR was achieved. Time intervals selected for analysis included time taken for clearance of peripheral circulating blasts; time to reach nadirs for WBC, ANC and ALC; and time to ANC recovery (from ANC nadir to 〉 500/µL). Tc was assessed as a function of WBC, ANC and ALC measurements (at the above predefined time points); time intervals; and magnitude of drop and rise in WBC, ANC and ALC (log reductions and improvements in counts) using multivariable logistic and Cox proportional hazards models and stepwise regression using Akaike’s Information Criterion (AIC) for model selection. Due to multiple testing, parameters are reported as significant if p 500/µL was significantly associated with delayed Tc (p

Description: Background: Acute Myeloid Leukemia (AML) patients (pts) being screened for clinical trials are often excluded based on laboratory values outside the normal range because of concerns of early treatment-related toxicities that can lead to adverse outcomes including death or delayed time to complete remission (CR). It has been shown that the time to achieve CR (Tc) has greater prognostic value in predicting survival than achieving CR per se (Estey et al., Blood 2002). In this study we assessed correlations between pretreatment risk factors and early (within 30 days of induction) treatment-related non-hematologic toxicities (TNHT) following IC, and between these toxicities and Tc and the probability of achieving CR. Methods: Adult pts diagnosed with AML (excluding acute promyelocytic leukemia) at the Cleveland Clinic from 10/08 - 11/12 who underwent IC with 7+3 (cytarabine and anthracycline) and had complete toxicity data were included. Variables including demographics, AML disease characteristics, abnormal laboratory measurements at diagnosis and during treatment, treatment response, and ICU stay, were assessed. The outcome of interest were development of non-fatal early TNHT and its effect on CR and Tc. TNHT were mapped as linear distance beyond the normal laboratory range and were set to zero if within limits. This was done for serum sodium (Na), potassium (K), bicarbonate, liver enzymes (AST, ALT), total bilirubin, INR (international normalized ratio), serum creatinine and albumin. These metrics were analyzed as a function of covariates at diagnosis using standard linear regression. They were then treated as covariates in logistic regression models of CR and in linear models of Tc. Akaike’s Information Criterion (AIC) was used in stepwise logistic regression model selection. Due to multiple testing, parameters are reported as significant only if p40, 12%) and one was underweight. All patients developed TNHT following IC: 98% (n=89) had electrolyte abnormalities, 26% (n=24) had elevated serum creatinine levels and 99% (n=89) had abnormal liver function indicated by AST, ALT, bilirubin, albumin and INR. Overall, 68% pts achieved CR, 9% (n=8) had complete response with incomplete recovery of counts, 10% (n=9) had persistent disease and in 12, determination of CR was not done due to early death or severe debilitation. Of all pretreatment variables, advancing age correlated with worsening hypoalbuminemia (p=0.0076); higher WBC with worsening hyperkalemia (p=0.001); absolute neutrophil counts with high K (p=.0002); and LDH with high K levels (p

Description: Introduction Immunoglobulin light chain amyloidosis (AL Amyloidosis) is a plasma cell disorder characterized by deposition of misfolded insoluble protein fibrils (composed of monoclonal κ or λ light chains) in tissues causing progressive organ dysfunction. Chemotherapy and autologous stem cell transplant (ASCT), when eligible, are standard treatment options but relapses remain inevitable for most patients. However, there is a paucity of literature describing relapsed or refractory patients. We performed a retrospective study to analyze the outcomes upon relapse and the impact of type of therapy and retreatment with the same therapy at relapse. Methods Clinical and laboratory data of 1327 consecutive patients with systemic AL amyloidosis seen at Mayo Clinic within 90 days of their diagnosis, between 2006 and 2015, was collected by chart review and analyzed retrospectively. Of these patients, 219 (16.5%) were lost to follow-up. Among the remaining 1108 patients, 366 patients experienced a documented hematological or organ relapse or progression requiring change of first line or start of second line therapy and form the current study population. Overall survival (OS) was calculated from start of second line treatment or progression mandating therapy until death from any cause or the date of last follow up. The OS was estimated using the Kaplan-Meier method and log rank test was used to estimate the difference in survival curves. Results The median age was 62.8 years (36.1 - 85.3); 63.1% were males; 64.7% / 59.3% / 11.4% had cardiac / renal / hepatic involvement and 24.2% / 32.1% / 23.3% / 20.3% had MS I/II/III/IV. The median estimated follow up for this cohort was 69.4 months (95% CI; 64.4, 76.8) from the start of first line therapy and 45.2 months (95% CI; 36.5, 50.6) from the start of second line therapy or progression requiring treatment. The median time to second line treatment or relapse /progression mandating therapy was 16.2 months (1-93) from the start of first line therapy. At relapse, 14 patients underwent ASCT, 165 were treated with proteasome inhibitor (PI) based therapy, 83 with immunomodulator (IMiD) based therapy, 33 with alkylator based therapy, 15 with a combination of PI and IMiD, 10 with steroids, 8 with other therapies and 38 did not receive treatment. Among the 366 patients, 124 (33.9%) required change or reinstitution of therapy during follow up at the time of analysis. The median time to third line treatment or relapse /progression mandating therapy was 31 months (95% CI; 24, 40.5) from the start of second line treatment. The median overall survival (OS) was 76.4 months (95% CI; 65.2, 83.6) from the start of first line therapy and 38.8 months (95% CI; 29.6, 52.6) from the start of second line therapy. The type of therapy at relapse (ASCT vs PI vs IMiD vs melphalan vs steroids and others) did not alter the time to next therapy (ASCT, 43.1m; PI, 31m; IMiD, 37m; melphalan, 20.8m; steroids and others, 20m; p=0.3) and OS (ASCT, 66.9m; PI, 51.1m; IMiD, 51.3m; melphalan, 37.2m; steroids and others, 80.7m; p=0.9) from the start of the second line treatment; as depicted in Figure 1. Retreatment with a different drug class (as the first line treatment) at relapse significantly reduced the time to next treatment (32.3m vs 22 m; p= 0.01) as compared to same therapy; but did not have any impact on survival (30.8m vs 51.1m; p = 0.5); as presented in Figure 2. Conclusion This study provides novel information about outcomes of patients with systemic AL amyloidosis who relapse or progress after first line therapy which could be useful in planning salvage therapies and designing clinical trials. Retreatment with a different therapy at relapse improves time to next therapy but does not impact OS. Hence, we conclude that the patients can fare well post relapse/ progression and can benefit from various treatment regimens including retreatment with the same agent.

Description: Introduction: IgM light chain amyloidosis (AL) is a rare complication of IgM associated disorders, with very limited data on biology and outcomes. Our study compares the clinical characteristics, laboratory findings and outcomes in a large cohort of patients with IgM vs. non-IgM AL to delineate the underlying disease biology of this entity. Methods: Patients with newly diagnosed AL (2006-15) were identified from a prospectively maintained institutional database and grouped by IgM heavy chain. Bone marrow (BM) morphology was reviewed by an expert hematopathologist (RLK). FISH testing included probes for t(11;14) and trisomies of odd numbered chromosomes. MYD88L265P testing was carried out by allele specific PCR and CXCR4WHIM mutation testing was performed by bridged nucleic acid (BNA)-enhanced Sanger sequencing. Results: Patients with IgM AL comprised 6.6% (75/1128) of the study cohort. Baseline characteristics are listed in Table 1. IgM AL patients were older and had a higher proportion of males. They had less frequent cardiac involvement (60 vs. 75%) and less frequent involvement of 〉 1 organ. Light chain burden was lower in this group (dFLC 12.5 vs. 22.7 mg/dL), while there was no difference in BM clonal cell percentage (10% each). Morphology: BM morphology in 71 patients with IgM AL revealed a pure plasma cell disorder (PPCD type) in 25% (n=18); low-grade B-cell lymphoma (LGBCL) with plasmacytic features (LPL type) in 62% (n=44) [well defined LPL: 38% (n=27), LGBCL with plasmacytic features: 24% (n=17)]; LGBCL, other: 6% (n=4). In the remaining 7%, three patients had other diagnoses and no BM disease in two patients. Median clonal cell % in LPL vs. PPCD type IgM AL was 20% vs. 5%, p

Description: Introduction: The clinical presentation and frequency of organ involvement are quite distinct in patients with IgM amyloidosis compared to patients with non-IgM amyloidosis, with less heart involvement and more nerve, soft tissue and lung involvement in IgM patients. It has been observed that immunoglobulin light chain variable region (IGVL) gene and gene family of the plasma cell clone impact phenotypic manifestations in AL amyloidosis, particularly organ tropism. (Kourelis et al. Blood. 2017;129). Given the variability in clinical features amongst patients with IgM vs. non IgM AL amyloidosis, we hypothesized that IGVL gene usage would be different between these two groups. Methods: Patients with newly diagnosed IgM and non-IgM amyloidosis seen at our institution from 01/2006 to 12/2015 were identified. IGVL gene usage was assessed by liquid chromatography tandem mass spectrometry (LC/MS/MS) as previously described. (Vrana et al Blood 2009;Dasari et al J of Proteome Res; Kourelis et al. Blood. 2017). Mass spectrometry data for IGVL analysis was obtained from clinically available data. LC/MS/MS was performed on available archival specimens when such data was not available clinically. Results: Patients with newly diagnosed amyloidosis who had sufficient mass spectrometry data on fat aspirate or tissue biopsy for IGVL gene usage identification were included (IgM AL, N=44 and Non-IgM AL, N=391). Clinical Features: As expected, differences were noted in baseline characteristics of patients with IgM vs. non-IgM AL amyloidosis. Patients with IgM amyloidosis were older (68 vs. 64 years, p=0.04) and more likely to have kappa as the involved light chain (34% vs. 25%, p=0.2), though the difference did not reach statistical significance. IgM amyloidosis patients had lower difference in involved and uninvolved free light chains (dFLC) (15.5 vs. 25.8 mg/dL, p=0.01) and lower NTProBNP levels (median: 1987 vs. 2655 pg/mL, p=0.02) compared with non-IgM amyloid patients. Presence of t(11;14) was less common by FISH (30% vs. 48%, p=0.1), though the difference did not reach statistical significance. Patterns of organ involvement were different, with heart involvement being less frequent in IgM patients (64% vs. 76%), while peripheral nerve (30% vs. 18%, p=0.05), soft tissue (41% vs. 21%, p=0.005) and lung involvement (7% vs. 3%, p=0.1) were more common in patients with IgM vs. non-IgM AL amyloidosis. There was no difference in liver (9% vs. 15%), kidney (50% vs. 51%) GI (23% vs. 25%) or autonomic nervous system involvement (18% vs. 14%). IGVL Gene Usage: As shown in Figure 1, IGVL usage differed across the two groups. In the lambda group, LV2-08 (14% vs. 2%, p

Description: Introduction: With the expanding use of CAR-T cell therapy, which is associated with serious adverse effects (AEs), there is a need to characterize the patient's experience over time to guide patient/provider education, and help optimize symptom management. This study reports on longitudinal evaluation of patient-reported quality of life (QOL) and symptom burden of CAR-T cell therapy compared with established forms of cellular therapy i.e autologous stem cell transplant (autoSCT) and allogeneic SCT (alloSCT). Methods: Patients with hematologic malignancies were prospectively recruited in three cohorts: CAR-T, autoSCT and alloSCT. The primary endpoint was change in QOL from baseline, using the FACT-G questionnaire. Secondary endpoints were patient-reported AEs (PRO-AEs) using 7 items from the PRO-CTCAE and assessment of cognition/memory using the NeuroQOLv2 questionnaire. PRO-CTCAE data was graded using a composite score (combining frequency, severity, and interference) and rates, using a method adjusting for pre-existing baseline symptoms, were compared using Fisher's exact test. We also evaluated the time profile of PRO-AEs using the Toxicity over Time (ToxT) approach, a longitudinal approach to AE analysis (Thanarajasingam Lancet Onc 2016). Patients completed questionnaires at baseline, week 2 and monthly thereafter. Results: From 07/2018 to 06/2019, 93 patients were recruited (CAR-T: 20; autoSCT: 37; alloSCT: 36). At data cut-off, week 2 and months 1, 2 and 3 data were available in 74, 62, 46 and 35 patients, respectively. There was no difference in patient age across the 3 groups (median age 63, range 23-77; p=0.26). Baseline QOL by FACT-G total score (mean=83.4, SD=14.7; p=0.77), side effect bother by FACT-G GP5 (66/93 [71%] a little bit or less; p=0.72), activities and function (70/93 [75%] fairly normal activities or no limitations; p=0.68) and cognition by NeuroQOL t-score (mean=52.2, SD=8.13; p=0.39) were similar across 3 groups at baseline. The CAR-T group experienced significantly less worsening in QOL (FACT-G) than both autoSCT and alloSCT groups (Fig. 1a). Worsening in overall QOL nadired at week 2, after which QOL gradually returned to baseline in all groups. When comparing changes from baseline in overall QOL, statistically significant differences between groups were evident at week 2 (CAR-T vs autoSCT p
