Abstract Background: MM is the second most common hematologic malignancy, which despite significant therapeutic advancements, remains incurable. The complexity of MM and its intricate management creates substantial informational demands for patients navigating their care. Methods: A cross-sectional survey study (Mayo Clinic IRB # 25-004671) was conducted to assess MM patients’ awareness about disease basics. A voluntary English language survey (47 questions) encompassing multiple domains of patient MM awareness was administered (REDCap) via the patient EMR portal (Mayo Clinic) and MM support groups nationally. Responses were analyzed using descriptive and inferential statistics (R; Bluesky Statistics, V 10.3.4). Multiple model logistic regression was used for multivariate analysis using age (≤70 or >70 yrs), gender, education (high school or less vs bachelor's and above), income (≤$74999 vs ≥$75000) and insurance status (private vs public). Results: The survey was completed by 2353 patients (pts) with 2177 MM (83.4% active, 16.6% smoldering) and 176 MGUS. Among MM pts median age was 63 yrs with 52.5% males, 91.5% white and 95.7% non-Hispanic. 17.5% had a prior diagnosis of MGUS and 20.2% of smoldering MM prior to MM, and 79.5% were not aware of MM prior to their own diagnosis. Majority (77%) depended most on their doctors to gain MM information but 24.3% reported not having sufficient discussion about MM at diagnosis. 31.2% were not sure what type of MM they had, 22.9% could not correctly report the cell of MM origin (plasma cell), 40.6% did not receive MM stage information at diagnosis, 45.4% were either unsure or reported wrong risk factors for MM and 22% were unsure or mistaken about MM symptoms. Majority (62.9%) did not understand genetic risk categories of MM, 32.3% did not report adequate understanding of MM tests and 31.9% did not understand the difference between response and remission. 57.5% reported not understanding about MRD status and 57.1% never had MRD testing. Majority (86.8%) felt they got adequate opportunity to participate in treatment decisions but only 54.2% felt confident in managing MM with their current knowledge and 28.2% had not discussed their prognosis although 77.7% wanted to know about it. Majority (64.4%) felt they had knowledge gaps about MM and its management. Multivariate analysis showed that females were less likely (OR 0.67) while those with public insurance were more likely (OR 1.35) to report receiving adequate information at diagnosis. Older pts (OR 0.55), males (OR 0.43), with lower education (OR 0.5), lower income (OR 0.5) and public insurance (OR 0.72) were less likely to identify the cell of MM origin correctly. These same groups were significantly less likely to be aware of types of MM as well. Older pts (OR 0.73), with lower education (OR 0.6), lower income (OR 0.77) and public insurance (OR 0.76) were less likely to be aware of MM genetic risk categories. Females (OR 0.81), with lower education (OR 0.68) and lower income (OR 0.63) were less likely to understand MM lab tests. Females and those with lower income were significantly less likely to report receiving adequate information about treatment options. Females reported that they did not get adequate opportunities to participate in treatment decisions (OR 0.65). Older pts, and those with lower income, lower education or public insurance were less likely to understand minimal residual disease (MRD) and all these groups were less likely to have had MRD testing. Those with lower income (OR 0.75) and lesser education (OR 0.72) felt less confident in managing MM with current knowledge. Older pts, females and those with lesser education, lower income and public insurance were also significantly less likely to have discussed about MM prognosis. Conclusion: This study demonstrates substantial basic knowledge deficits integral to managing and prognosticating MM among patients. Patients from unfavorable sociodemographic-economic groups were more likely to have awareness gaps and report lack of information which is integral to having adequate understanding of MM being provided to them. These findings highlight the critical need for structured, comprehensive educational interventions that address fundamental disease concepts to empower pts, overcome healthcare disparities, and engage pts in shared decision-making.

Abstract Background: The phase II and III GRIFFIN and PERSEUS studies evaluated DVRd vs. VRd in NDMM pts that were transplant eligible (TE). These studies included consolidation (cons) and dual agent maintenance (maint) with dara and len (DR). Little is known about the efficacy of DVRd in RW practice including frequency of bor use, use of cons, use of DR maint, and subsequent treatment after progression (PD) on DVRd. We aim to evaluate the RW efficacy of NDMM pts treated with DVRd across the tri-site Mayo Clinic Comprehensive Cancer (MCCC). Methods: We retrospectively analyzed the medical records of pts treated with DVRd between June 2018 and June 2024 at the MCCC. Outcomes were estimated using the Kaplan-Meier method. Results: 464 pts were included; 278 pts were male, and the median (m) age of MM diagnosis was 64 years (yr). 114 pts had ISS III, 205 pts had R-ISS III, 266 pts had high risk (HR) FISH, 80 pts had extramedullary disease, 165 pts had ultra HR disease (dz) (as per 2025 IMS/IMWG consensus), and 47 pts had renal insufficiency (RI) with creatinine >2 mg/dL. Starting len dose was 25mg in 356 pts, 15 mg in 40 pts and ≤10mg in 65 pts. 399 pts received bor 1x per week and 63 2x per week, 91 pts received 1-2 cycles of a different regimen prior to DVRd due to hospitalization (n=23), RI (n=38), poor performance status (n=6), other (n=34). 315 (67.9%) pts underwent autologous transplant (ASCT). The m number of induction cycles was 5; 4 for pts who underwent ASCT and 6 for pts who did not. The best ORR to induction for pts who underwent ASCT was 98% with 247 (79%) achieving ≥VGPR, and 82 (26%) achieving minimal residual disease negativity (MRD-) to at least 10-5. The best ORR for pts who did not undergo ASCT was 87%. For those who underwent ASCT, (96% with melphalan 200mg/m2), the ORR at day 100 was 97% with 56% achieving MRD-. At 1-yr post ASCT, 30% (93/312) were MRD-. 42 pts (13%) received post ASCT cons with DVRd for a m of 2 cycles. 281 pts received post ASCT maint including 107 (38%) len, 53 (19%) bor-len, 91 (32%) dara-len, 14 (5%) dara, 16 (6%) other. 61(13%) pts had change in treatment, due to change to second line therapy (35; 55%), discontinuation (d/c) of len (11; 17%), d/c of dara (3; 5%), d/c of bor (15; 23%), d/c of dex (0; 0%). The m follow-up time for all pts was 26 months (mo) (17-39). The m PFS of pts who underwent ASCT was not reached (NR), and was 57 mo (52-NA) for pts who did not undergo ASCT. For pts who underwent ASCT, the PFS at 24mo for pts who did not have HR FISH was 93% (88-99%) compared to 80% (73-88%) for pts with HR FISH (p=0.12) and 77% (68-87%) for pts with ultra-HR dz (p=0.013).The PFS at 24mo of pts with RI who underwent ASCT was 81% (66-98%) compared to 86% (82-92%) for those without RI, p=0.57. The PFS at 24mo of pts with RI who did not undergo ASCT was 53% (28-100%) compared to 64% (55-75%) for those without RI, p=0.42. The ORR and MRD- rate for pts who received once-weekly bor was 94% and 24%, compared to 94% and 27% for pts who received 2x weekly bor (p=0.85, p=0.93). For pts who underwent ASCT, the PFS at 24mo for pts who received len maint was 91% vs. 83% for pts who receive dual agent maint (DR or VR) (p=0.25), although pts who got dual agent maint were more likely to have HR FISH than pts who received len maint (p<0.001). The PFS at 24mo for pts that received post-ASCT cons was 91% compared to 85% for those that did not (p=0.53); pts who got post-ASCT cons were more likely to have HR FISH (p=0.07). For pts that underwent ASCT, the 3 yr PFS rate is 85% and the 3 yrs OS rate is 96%. For pts that did not undergo ASCT the 3 yrs PFS rate is 60% and the 3 yr OS rate is 85%. 55 pts had functional HR (FHR) MM (relapse within 18 mo) and m PFS for FHR pts who underwent ASCT was 15 mo (11-NA), while m PFS was NR for pts without FHR MM (p<0.001). 79 pts relapsed after 1st line DVRd. The most common 2nd line therapies (tx) were dara-carfilzomib (K)-D, dara-pomalidomide(P)-D, KPD, and other. The m follow-up time from 2nd line tx was 10 mo, the best ORR to 2nd line tx was 76%, and the m PFS with 2nd line tx was 18 mo (7-NA). Conclusion: In this RW analysis, the efficacy and survival outcomes of NDMM pts treated with DVRd was comparable to that reported in the PERSEUS and GRIFFIN trials, although MRD- rates appear lower. DR maint and post-ASCT cons use was not common and was used more frequently in pts with HR FISH. Pts can be effectively salvaged following PD on front-line DVRd with available tx.

Introduction: Myeloma therapeutics have tremendously improved in recent times, leading to unprecedented outcomes. Timely initiation of effective treatment is vital to improving survival and quality of life. Patient refusal to receive treatment is infrequent but certainly leads to increased morbidity/mortality. We studied factors associated with treatment refusal. Methods: The National Cancer Database (NCDB) was queried for adult patients diagnosed with MM between 2004-2021. Those who refused treatment for initial management despite physician's recommendation were identified. Patients with multiple primary malignancies or unknown treatment status were excluded. Patients' demographics and socioeconomic factors were collected. Kaplan-Meier and multivariate Cox regression were used to evaluate the likelihood of treatment refusal in the whole cohort and in each racial/ethnic group. Results: Out of 86,350 eligible patients with MM who were recommended to initiate therapy, 2,508 (2.9%) did not receive any treatment due to refusal. Of these, 52.6% were females, 64% were non-Hispanic White (NHW), 21.3% were non-Hispanic African American (NHAA), and 5.2% were Hispanic. On multivariate analysis, patients who were treated at comprehensive and integrated facilities were more likely to refuse treatment as compared to those at academic facilities (OR=1.36; 95% CI: 1.22-1.52, p<0.001 and OR=1.22; 95% CI: 1.07-1.4, p=0.004, respectively). Patients on Medicare (OR=1.42; 95% CI: 1.16-1.73, p<0.001), and presence of higher Charlson Comorbidity Index (CCI) also had a higher likelihood of refusing treatment. Lower refusal rates were seen for male gender (OR=0.83; 95% CI: 0.76-0.91, p<0.001), NHW racial/ethnic group (as against NHAA; OR=0.34; 95% CI: 0.16-0.71, p=0.004), being insured (OR=0.69; 95% CI: 0.52-0.93, p=0.015), having private insurance (compared to Medicaid; OR=0.47; 95% CI: 0.38-0.59, p<0.001) and having a higher income level (OR=0.82; 95% CI: 0.70-0.96, p=0.013). Among NHAA patients, 2.8% refused treatment and were more likely to have Medicare (OR=1.4; 95% CI: 1.03-1.9, p=0.032). Having private insurance (compared to Medicaid; OR=0.61; 95% CI: 0.43-0.88, p=0.008) had a lower likelihood of refusing treatment. Among NHW, 2.9% refused treatment and they were more likely to be treated at community, comprehensive and integrated facilities compared to academic facilities (OR=1.39; 95% CI: 1.12-1.73, p=0.003, OR=1.54; 95% CI: 1.33-1.77, p<0.001 and OR=1.38; 95% CI: 1.16-1.64, p<0.001, respectively), be from rural areas (OR=1.43; 95% CI: 1.05-1.96, p=0.025), and have a higher CCI. On the other hand, male gender (OR=0.79; 95% CI: 0.72-0.89, p<0.001), private insurance (compared to Medicaid; OR=0.42; 95% CI: 0.30-0.59, p<0.001) and higher income level (OR=0.80; 95% CI: 0.66-0.98, p=0.029) had a lower likelihood of refusing treatment. Among Hispanic patients, 2.3% refused treatment and were more likely to have Medicare (OR=1.96; 95% CI: 1.13-3.4, p=0.016), while those with private insurance (compared to Medicaid; OR=0.32; 95% CI: 0.14-0.73, p=0.007) had a lower likelihood of refusing treatment. Conclusions: This large real-world analysis highlights the intricate sociodemographic and economic factors that affect the decision of a MM to not proceed with the recommendation for treatment. (1) NHW are less likely to refuse treatment as compared to NHAA. (2) Insurance status is an important driver of refusal and transcends race/ethnicity. Furthermore, in this study, we highlight characteristics that are specific to different racial/ethnic groups like CCI which affect only certain racial/ethnic groups. This provides an opportunity to develop targeted interventions such that the benefit of therapeutic advancements can be realized by all.

Introduction: Ven is a BCL2 inhibitor that has shown clinical efficacy in RRMM patients (pts) particularly those that harbor t(11;14). Ven has been evaluated in clinical trials as a single agent, in combination with dexamethasone (dex), immunomodulatory drugs (IMiD), proteasome inhibitors (PI), and anti-CD38 monoclonal antibodies (MAb) yet its place in the therapeutic landscape remains in question. In this retrospective analysis, we aim to evaluate the real-world efficacy of Ven-based regimens in RRMM pts treated outside of a clinical trial across the 3-site MCCC. Methods: We retrospectively analyzed the medical records of pts with RRMM treated with Ven-based regimens between January 2015 and October 2023 at the MCCC. Refractoriness was defined by progression on or within 60 days of stopping treatment. Categorical variables were compared with Chi-square tests and continuous variables were compared with t-tests. Outcomes were estimated using the Kaplan-Meier method and curves were compared between the groups using log-rank tests. Results: 83 pts were included in the analysis. The median age was 71 (39-93), 63% were male, 93% were white, 27% had ISS III, 18% had high risk cytogenetics (HRCyto), 76% had t(11;14), the median prior lines of therapy (LOT) was 4 (1-15), 68% received ≥ 4 prior LOT, 87% received prior autologous transplant, 58% were triple-class refractory (TCR), 64%/23% were penta-drug exposed/refractory (PDE/R), 8% received prior BCMA-directed therapies (BDT), 58% received Ven+dex, 25% received Ven+PI +/-dex, 6 % received Ven+anti-CD38 MAb+/-dex and 11% received Ven+other. The median follow-up time from start of a Ven-based regimen was 29 months (mo). The median Ven dose was 800mg (20-1600) with 25% of pts receiving Ven ramp-up dosing. The overall response rate (ORR) to a Ven-based regimen was 58% and was 64% for pts with t(11;14) and 40% for pts without t(11;14); p=0.06. Ven-treated pts with HRCyto had inferior PFS (3mo) and OS (8mo) compared to patients who did not have HRCyto who had a PFS of 9mo (p=0.020) and OS of 80mo (p<0.001). The ORR for TCR and PDR pts were 52% and 42%, respectively. No significant ORR differences were noted across the different Ven-based regimens (p=0.32). The median PFS for pts with t(11;14) was 10mo compared to 2mo for pts w/o t(11;14); p=<0.001. The median OS for pts with t(11;14) was 80mo compared to 10mo for pts without t(11;14); p=0.001. Ven-treated pts who received 1-3 prior LOT has superior ORR, median PFS, and median OS; 89%, 25mo, and 99mo, respectively, compared to pts who received ≥4 prior LOT who achieved an ORR of 43% (p<0.001), median PFS of 5mo (p<0.001) and median OS of 25mo (p<0.001). Ven-treated pts that were TCR had inferior PFS (5mo) and OS (26mo) compared to pts who were not TCR who achieved a PFS of 12mo (p<0.001) and a median OS of 80mo (p=0.02).Ven-treated pts that were PDR had inferior PFS (4mo) and OS (22mo) compared to pts who were not PDR who achieved a PFS of 9mo (p<0.001) and a median OS of 80mo (p=0.02).Ven-treated pts who received prior BDT (n=7) achieved an ORR of 29% and had a median PFS and OS of 2mo and 6mo, respectively on a Ven-based therapy. 59 pts received additional therapy in the post Ven-progression setting. The ORR to post-Ven progression therapies was 53% (n=31/59), the median PFS was 9mo and median OS was 35mo. The most common post-Ven progression regimens used were PI-based (n=16; ORR=56%), anti-CD38 MAb-based (n=14; ORR=50%), BDT (n=12; ORR=83%), selinexor-based (n=3; ORR=0%) with BDT resulting in highest ORR (p=0.048) and PFS (p=0.005). Conclusions: Ven-based regimens are effective in heavily pre-treated pts with RRMM however they are more effective when used within 1-3 prior LOT, in pts with t(11;14), and in pts without HRCyto, TCR or PDR MM. BDT appear to be the most efficacious therapies in the post-Ven progression setting.

Introduction: Overall outcomes have improved significantly for MM with a 5-year relative survival rate currently of >60%. With effective treatments, patients from all clinical strata and age groups are expected to have meaningful benefit, but despite excellent therapeutic advancements, some patients continue to have early mortality. We conducted this study to investigate factors associated with early mortality. Methods: The National Cancer Database (NCDB) was queried for adult patients with NDMM between 2004 and 2021. We excluded patients with multiple primary malignancies or lost to follow-up (unknown vital status or last contact). Early mortality was defined as death within 6 months from MM diagnosis. Patient demographics and socioeconomic factors available in NCDB were collected. Kaplan-Meier and multivariate Cox regression were used to evaluate the likelihood of early mortality in this large cohort of MM patients using multi-variate analysis. Results: Out of 255,579 eligible patients with MM, 35,302 (13.8%) died within the first 6 months of diagnosis and 108,534 (42.5%) died after the first 6 months of MM diagnosis. The early mortality cohort had significantly higher mean age at MM diagnosis (73.9 vs. 68.5 years, p<0.001) but no significant differences were noted for gender distribution. There was a statistically significant difference for racial/ethnic distribution (p=0.019), but the percentages were very similar among non-Hispanic White (69% vs 68.1%), non-Hispanic African American (18% vs 18.7%) and Hispanic patients (4.7% vs 4.8%). Patients in the early mortality cohort were less likely to be treated at academic institutions (28.4% vs 37.8%, p<0.001) and have significantly different distribution by insurance type (less likely to have private insurance; 17.3% vs. 30%, more likely to have Medicare; 72.1% vs. 58.7%, p<0.001) although overall insurance access was similar between the two groups (95.3% vs 95.2%, p=0.283). Early mortality was associated with higher morbidity scores as per the Charlson-Comorbidity Index (CCI) (p<0.001) and were more likely to have not received any treatment for MM (53.2% in early mortality group vs. 28.4% in late mortality, p<0.001). Early mortality was also associated with a lower literacy rate (high school graduation rate 21.2% vs. 19.7%, p<0.001) and lower household income (<$46,277; 19.1% vs. 17.7%, p<0.001). Conclusion: This large real-world analysis shows that despite therapeutic advances in recent years, there is a significant percentage of patients with NDMM in the U.S. who suffer from early mortality. There are several sociodemographic and economic factors that were found to be associated with early mortality, with some showing clear trends (older age, treatment facility type, insurance type, income, education, CCI), while others like racial differences were significant but somewhat ambiguous. Identifying and addressing these factors at diagnosis will help provide personalized care plans and minimize early mortality.

Abstract Multiple myeloma (MM) therapeutics have evolved tremendously in recent years, with significant improvement in patient outcomes. As newer treatment options are developed, stem cell transplant (SCT) remains an important modality that provides excellent disease control and delays the progression of disease. Over the years, SCT use has increased overall in the U.S., but two distinct gaps remain, including suboptimal use overall, and racial-ethnic disparities. We evaluated the National Cancer Database (NCDB) to study what sociodemographic factors might play a role within a given racial-ethnic group leading to disparate SCT utilization, such that targeted approaches can be developed to optimize SCT use for all. In nearly 112,000 cases belonging to mutually exclusive categories of non-Hispanic Whites (NHW), non-Hispanic Blacks (NHB), Hispanics, non-Hispanic Asians (NHA), and others, we found certain factors including age, comorbidity index, payor type, facility type (academic vs. community) and facility volume to be uniformly associated with SCT use for all the racial-ethnic groups, while gender was not significant for any of the groups. There were several other factors which had a differential impact on SCT utilization among the various race-ethnicity groups studied, including year of diagnosis (significant for NHW, NHB and Hispanics), income level (significant for NHW and Hispanics), literacy level (significant for NHW and NHB), and geographic location of the treatment facility (significant for NHW and NHA). The suboptimal SCT utilization overall in the U.S., suggests that there may be room for improvement for all, even including the majority NHW, while we continue to work on factors that lead to disparities for the traditionally underserved populations. This study helps identify sociodemographic factors that may play a role specifically in each group and paves the way to devise targeted solutions such that resource utilization and impact can be maximized.

SummaryThis phase II study evaluated time‐limited (24 cycles) treatment with ibrutinib and ixazomib in newly diagnosed (NDWM; n = 9) and relapsed/refractory (RRWM; n = 12) Waldenström macroglobulinaemia (WM). The overall response rate (ORR) was 76.2% (n = 16) in 21 evaluable patients with no patient achieving a complete response (CR). The median duration of treatment was 15.6 months, and after a median follow‐up time of 25.7 months, the median progression‐free survival (PFS) was 22.9 months. While the primary end‐point was not met (CR rate at any time) and 28.5% discontinued treatment due to toxicity, ibrutinib plus ixazomib led to a clinically meaningful ORR and PFS. Combined Bruton's tyrosine kinase (BTK) and proteasome inhibition merits further evaluation in WM.

Introduction: Treatment options for multiple myeloma (MM) are evolving rapidly with recent introduction of BCMA-targeting CAR-T (Ide-cel, Cilta-cel) and bispecific antibody (Bi-Ab; Teclistamab) alternatives. These are complex, logistically demanding therapies, and patient awareness/knowledge can affect treatment decisions. There are traditionally underserved patients in MM, and awareness among them must be investigated to uncover disparities which may impact their access to and choice of novel therapies, contributing to disparate outcome. Methods: The study involved an anonymous 25-question online English language survey covering basic demographics, understanding of available T-cell directed MM treatments (CAR-T, Bi-Ab), and preferences for these agents. MM patients within the Mayo Clinic database and members of International Myeloma Foundation's MM support groups were sent a link to the voluntary survey. The survey was active from March 30 until July 12, 2023. Descriptive statistics were calculated with R language (Bluesky Statistics, V7.40), and categorical variables among outcome demographic groups were compared using Pearson Chi-square test (p-value ≤0.05 considered statistically significant). Multiple model logistic regression was used for multivariate analysis amongst statistically significant outcomes. Results: The survey had 2370 respondents with median age 68 years (range: 30-95) and median age at MM diagnosis 62 years (range: 18-88). Time since diagnosis was <5 years in 59.5%. Majority of the respondents (89.4%) were non-Hispanic Whites (NHW). Maximum education categories were high school (10.9%), some college but no degree (18.1%), associate/bachelor (39.7%), and master's/professional (32.3%). Geography and type of residence were reported as: West (24%), Midwest (46.2%), Northeast (3.3%), South (24.8%), outside U.S. (1.7%), and rural (26.7%), urban (21.4%), suburban (51.9%). The goals of MM treatment in order of reported importance were complete remission (66.1%), longer survival (55.3%) and low symptom burden (43.3%). Only 6.5% and 2.6% of respondents had received CAR-T and Bi-Ab, respectively, while 27.9% and 70.5% had never heard of CAR-T and Bi-Ab, respectively. A high proportion of respondents did not understand the risks/benefits of CAR-T (65.5%) or Bi-Ab (90.7%). Given a preference among CAR-T products, 5.4% would prefer Cilta-cel, 1.9% Ide-cel and 92.7% were not sure/no preference. Amongst only those who reported understanding the risks/benefits of CAR-T, the majority (73%) said they would prefer Cilta-cel. The majority (87.5%) were not sure of any differences between the two CAR-T products while some reported different targets (6.3%), response rate (5.9%), response duration (6.2%), side effects (4.9%), and manufacturing time (2.7%). The biggest concern for both CAR-T and Bi-Ab was side effects. Majority (89.4%) were not sure that Teclistamab Bi-Ab targeted BCMA, and nearly 70% felt that CAR-T was superior to Bi-Ab for treating MM. Reported sources of knowledge about MM treatment were healthcare team (82.6%), online resources (43.6%) and other patients/support groups (37.9%). Several demographic characteristics that significantly affected patient's responses to different questions in the survey. Selected questions and respondent categories with statistically significant results in multivariate analysis are shown in Table 1. Generally, higher education, living in northeast U.S., urban or suburban residency, and >5 years since MM diagnosis were associated with better awareness/understanding of CAR-T and Bi-Ab. Respondents with >70-year age were less likely to be aware of these agents or understand their risks/benefits. Race-ethnicity had no statistically significant associations in this cohort of predominantly NHW. Conclusions: This large cross-sectional study identifies lack of adequate awareness regarding CAR-T and Bi-Ab and provides a glimpse of current understanding of these complex therapies. There are disparate groups including rural, less educated, elderly and those with recent diagnosis of MM who have significantly lesser awareness. Some better-informed respondents had preferences among these treatments. Targeted awareness campaigns should be developed so that knowledge gaps can be bridged and patients across all sociodemographic groups are better equipped to take informed decisions about MM treatment.

Factor VII (FVII) is an important, vitamin K-dependent clotting factor. Acquired FVII deficiency is a rare entity that is associated with serious bleeding complications. We report a case of acquired FVII deficiency in a patient with recurrent chronic myeloid leukemia in blast crisis who developed bilateral retinal hemorrhages. The coagulopathy was corrected with the initiation of chemotherapy and subsequent reduction in peripheral blast count.

While immunotherapies, such as CAR T therapy and bi-specific antibodies, have revolutionized the treatment of multiple myeloma (MM), patients with AL amyloidosis have been excluded from trials with these agents due to concerns of underlying autonomic, cardiac, and renal dysfunction, leading to potentially fatal toxicities from these therapies. In this communication, we described the outcomes of two patients with AL amyloidosis and concurrent MM with underlying cardiac and/or renal dysfunction who underwent anti-BCMA CAR T cell therapy with ide-cel or cilta-cel, received cytokine release syndrome prophylaxis, and tolerated therapy well with manageable toxicities and achieved a MRD-negative state. We described the preliminary efficacy and safety of CAR T in patients with AL amyloidosis and highlighted the importance of patient selection and medical optimization of cardiac and renal function prior to CAR T.
