Abstract Myelodysplastic syndromes/neoplasms (MDSs) are heterogeneous stem cell malignancies characterized by poor prognosis and no curative therapies outside of allogeneic hematopoietic stem cell transplantation. Despite some recent approvals by the US Food and Drug Administration, (eg, luspatercept, ivosidenib, decitabine/cedazuridine, and imetelstat), there has been little progress in the development of truly transformative therapies for the treatment of patients with MDS. Challenges to advancing drug development in MDS are multifold but may be grouped into specific categories, including criteria for risk stratification and eligibility, response definitions, time-to-event end points, transfusion end points, functional assessments, and biomarker development. Strategies to address these challenges and optimize future clinical trial design for patients with MDS are presented here.

Background: Recent advancements in multiple myeloma (MM) diagnosis and treatment significantly improved patients' survival and quality of life. Severe Renal Impairment (RI) remains a significant challenge in newly diagnosed MM (NDMM), complicating treatment and affecting outcomes. Prior studies reported improved overall renal recovery in the era of novel therapies. However, there is a lack of evidence documenting the outcomes of patients presenting with severe RI. We present an updated analysis of the characteristics and outcomes of patients with NDMM presenting with severe RI in an ethnically diverse, low socio-economic population. Methods: A single-center retrospective review of patients with NDMM presenting to Montefiore Medical Center (Bronx, New York) was conducted from 2011-2023. Severe RI was defined as an estimated glomerular filtration rate (eGFR) of less than 30 mL/min/1.73 m². MM risk was assessed using the mSMART 3.0 tool. Results: Out of 284 patients with NDMM, 58 (20%) patients presented with severe RI. Black patients (p = 0.018) and older adults (64 years vs 60 years, p value 0.032) were more likely to present with severe RI. Severe RI at diagnosis correlated with high-risk myeloma (p = 0.002), high R-ISS stage (p < 0.001), and a lower likelihood of receiving stem cell transplants (p < 0.001). Among those with severe RI, 23/58 required dialysis of which 6/23 were taken off dialysis at last follow-up after renal recovery. Median eGFR at diagnosis, 6 months and 1 year after diagnosis was 11, 23 and 23.5 ml/min/1.73 m2, respectively. 14 out of 58 patients (39%) achieved renal recovery to eGFR > 30 one year post-diagnosis, with no significant difference in race, sex, or ethnicity. The most common first-line treatment for patients with severe RI was CyBorD (62%). The median time from diagnosis to first treatment (including plasma exchange) was 10 days. By the last follow-up, 35/58 patients (60%) had a stem cell transplant, with a median time from diagnosis to transplant of 275 days. The median overall survival (OS) for patients with severe RI at diagnosis was 49 months, while it was not reached for those without severe RI (p < 0.001). Early death (≤ 2 months after diagnosis) occurred in 2 patients, both with severe RI. Among patients with severe RI, multivariate Cox regression survival analysis showed that achieving free light chain (FLC) below 500 mg/L (HR 0.212, p < 0.001) and receiving a stem cell transplant (HR 0.209, p 0.002) improved outcome. Conclusions: Despite improvements in the life expectancy of patients with MM, severe renal failure remains a challenge, particularly among minorities. Socioeconomic factors need to be explored as a contributor to outcomes in patients with severe RI. Achieving FLC clearance and undergoing stem cell transplant may play a role in survival in patients with NDMM and severe RI.

ImportanceSystematic data on the association between anticancer therapies and thromboembolic events (TEEs) in patients with COVID-19 are lacking.ObjectiveTo assess the association between anticancer therapy exposure within 3 months prior to COVID-19 and TEEs following COVID-19 diagnosis in patients with cancer.Design, Setting, and ParticipantsThis registry-based retrospective cohort study included patients who were hospitalized and had active cancer and laboratory-confirmed SARS-CoV-2 infection. Data were accrued from March 2020 to December 2021 and analyzed from December 2021 to October 2022.ExposureTreatments of interest (TOIs) (endocrine therapy, vascular endothelial growth factor inhibitors/tyrosine kinase inhibitors [VEGFis/TKIs], immunomodulators [IMiDs], immune checkpoint inhibitors [ICIs], chemotherapy) vs reference (no systemic therapy) in 3 months prior to COVID-19.Main Outcomes and MeasuresMain outcomes were (1) venous thromboembolism (VTE) and (2) arterial thromboembolism (ATE). Secondary outcome was severity of COVID-19 (rates of intensive care unit admission, mechanical ventilation, 30-day all-cause mortality following TEEs in TOI vs reference group) at 30-day follow-up.ResultsOf 4988 hospitalized patients with cancer (median [IQR] age, 69 [59-78] years; 2608 [52%] male), 1869 had received 1 or more TOIs. Incidence of VTE was higher in all TOI groups: endocrine therapy, 7%; VEGFis/TKIs, 10%; IMiDs, 8%; ICIs, 12%; and chemotherapy, 10%, compared with patients not receiving systemic therapies (6%). In multivariable log-binomial regression analyses, relative risk of VTE (adjusted risk ratio [aRR], 1.33; 95% CI, 1.04-1.69) but not ATE (aRR, 0.81; 95% CI, 0.56-1.16) was significantly higher in those exposed to all TOIs pooled together vs those with no exposure. Among individual drugs, ICIs were significantly associated with VTE (aRR, 1.45; 95% CI, 1.01-2.07). Also noted were significant associations between VTE and active and progressing cancer (aRR, 1.43; 95% CI, 1.01-2.03), history of VTE (aRR, 3.10; 95% CI, 2.38-4.04), and high-risk site of cancer (aRR, 1.42; 95% CI, 1.14-1.75). Black patients had a higher risk of TEEs (aRR, 1.24; 95% CI, 1.03-1.50) than White patients. Patients with TEEs had high intensive care unit admission (46%) and mechanical ventilation (31%) rates. Relative risk of death in patients with TEEs was higher in those exposed to TOIs vs not (aRR, 1.12; 95% CI, 0.91-1.38) and was significantly associated with poor performance status (aRR, 1.77; 95% CI, 1.30-2.40) and active/progressing cancer (aRR, 1.55; 95% CI, 1.13-2.13).Conclusions and RelevanceIn this cohort study, relative risk of developing VTE was high among patients receiving TOIs and varied by the type of therapy, underlying risk factors, and demographics, such as race and ethnicity. These findings highlight the need for close monitoring and perhaps personalized thromboprophylaxis to prevent morbidity and mortality associated with COVID-19–related thromboembolism in patients with cancer.

Patients with multiple myeloma (MM) are at a high risk for developing cardiovascular complications. Global longitudinal strain (GLS) can detect early functional impairment before structural abnormalities develop. It remains unknown if reduced GLS is associated with reduced survival in patients with MM. We conducted a retrospective cohort analysis of patients diagnosed with MM between 1 January 2000 and 31 December 2017 at our institution. Patients with a 2D transthoracic echocardiogram completed within 1 year of MM diagnosis, left ventricular ejection fraction (LVEF) greater than 40%, and no history of myocardial infarction prior to MM diagnosis were included. GLS was measured using an artificial-intelligence-powered software (EchoGo Core), with reduced GLS defined as an absolute value of <18%. The primary outcome of interest was overall survival since myeloma diagnosis. Our cohort included 242 patients with a median follow up of 4.28 years. Fifty-two (21.5%) patients had reduced average GLS. Patients with reduced GLS were more likely to have an IVSd ≥ 1.2cm, E/E’ > 9.6, LVEF/GLS > 4.1, higher LV mass index, and low-voltage ECG. A Total of 126 (52.1%) deaths occurred during follow-up. Overall survival was lower among patients with reduced GLS (adjusted HR: 1.81, CI: 1.07–3.05).

ImportanceCytokine storm due to COVID-19 can cause high morbidity and mortality and may be more common in patients with cancer treated with immunotherapy (IO) due to immune system activation.ObjectiveTo determine the association of baseline immunosuppression and/or IO-based therapies with COVID-19 severity and cytokine storm in patients with cancer.Design, Setting, and ParticipantsThis registry-based retrospective cohort study included 12 046 patients reported to the COVID-19 and Cancer Consortium (CCC19) registry from March 2020 to May 2022. The CCC19 registry is a centralized international multi-institutional registry of patients with COVID-19 with a current or past diagnosis of cancer. Records analyzed included patients with active or previous cancer who had a laboratory-confirmed infection with SARS-CoV-2 by polymerase chain reaction and/or serologic findings.ExposuresImmunosuppression due to therapy; systemic anticancer therapy (IO or non-IO).Main Outcomes and MeasuresThe primary outcome was a 5-level ordinal scale of COVID-19 severity: no complications; hospitalized without requiring oxygen; hospitalized and required oxygen; intensive care unit admission and/or mechanical ventilation; death. The secondary outcome was the occurrence of cytokine storm.ResultsThe median age of the entire cohort was 65 years (interquartile range [IQR], 54-74) years and 6359 patients were female (52.8%) and 6598 (54.8%) were non-Hispanic White. A total of 599 (5.0%) patients received IO, whereas 4327 (35.9%) received non-IO systemic anticancer therapies, and 7120 (59.1%) did not receive any antineoplastic regimen within 3 months prior to COVID-19 diagnosis. Although no difference in COVID-19 severity and cytokine storm was found in the IO group compared with the untreated group in the total cohort (adjusted odds ratio [aOR], 0.80; 95% CI, 0.56-1.13, and aOR, 0.89; 95% CI, 0.41-1.93, respectively), patients with baseline immunosuppression treated with IO (vs untreated) had worse COVID-19 severity and cytokine storm (aOR, 3.33; 95% CI, 1.38-8.01, and aOR, 4.41; 95% CI, 1.71-11.38, respectively). Patients with immunosuppression receiving non-IO therapies (vs untreated) also had worse COVID-19 severity (aOR, 1.79; 95% CI, 1.36-2.35) and cytokine storm (aOR, 2.32; 95% CI, 1.42-3.79).Conclusions and RelevanceThis cohort study found that in patients with cancer and COVID-19, administration of systemic anticancer therapies, especially IO, in the context of baseline immunosuppression was associated with severe clinical outcomes and the development of cytokine storm.Trial RegistrationClinicalTrials.gov Identifier: NCT04354701

PURPOSE Impaired response to erythropoietin underlies ineffective erythropoiesis and anemia in myelodysplastic syndromes (MDS). We investigated whether treatment with lenalidomide (LEN), which augments erythropoietin receptor signaling in vitro, can restore and improve hemoglobin response to epoetin (EPO) alfa in patients with lower-risk, non-del(5q) MDS who have anemia that is refractory to or have low probability of benefit from treatment with recombinant erythropoietin. METHODS In a phase III, US intergroup trial, we randomly assigned patients to receive either LEN and EPO alfa or LEN alone following stratification by serum erythropoietin concentration and prior erythropoietin treatment. RESULTS A total of 195 evaluable patients were randomly assigned: 99 patients to the LEN-EPO alfa cohort and 96 to LEN alone. After four cycles of treatment, the primary end point of major erythroid response (MER) was significantly higher (28.3%) with the combination compared with LEN alone (11.5%) ( P = .004). Among 136 patients who completed 16 weeks of study treatment, 38.9% and 15.6% achieved MER, respectively ( P = .004). Additionally, minor erythroid response was achieved in 18.2% and 20.8% of patients, for an overall erythroid response rate of 46.5% versus 32.3%. Among LEN nonresponders, 38 crossed over to the addition of EPO alfa with 10 patients (26.3%) achieving a MER. Responses to the combined treatment were highly durable with a median MER duration of 23.8 months compared with 13 months with LEN alone. CONCLUSION LEN restores sensitivity to recombinant erythropoietin in growth factor–insensitive, lower-risk, non-del(5q) MDS, to yield a significantly higher rate and duration of MER compared with LEN alone (funded by the National Cancer Institute; E2905 ClinicalTrials.gov identifier: NCT02048813 ).

Background: Only a small subset of Lower risk (LR) MDS patients benefit from treatment with rhu-Erythropoietin (Epo). We previously reported that lenalidomide (LEN) restores sensitivity to Epo in MDS progenitors by inducing the formation of lipid rafts that are enriched for signaling competent, JAK2/Epo-receptor complexes (McGraw K, et. al. PLoS One 2014; Basiorka A, et. al. Cancer Res 2016). In the MDS-002 and MDS-005 trials, treatment with LEN monotherapy gave rise to RBC transfusion-independence (TI) in 26% of azanucleoside-naïve, transfusion-dependent (TD) LR, non-del(5q) MDS patients for a median of 10.2 and 7.75 months, respectively. In a pilot study of Epo-refractory LR-MDS patients, the addition of epoetin alfa (EA) to LEN treatment yielded erythroid responses in 28% of patients who were unresponsive to LEN alone, suggesting that LEN may overcome clinical resistance to augment response to rhEpo (Komrokji R, et. al. Blood 2012). To test this hypothesis, we performed a randomized phase III trial comparing treatment with LEN to LEN+EA in LR non-del(5q) MDS patients who were refractory to, or not candidates for treatment with rhEpo. Methods: Patients with Low or Intermediate-1 IPSS risk MDS with hemoglobin &lt;9.5 g/dL who were unresponsive to rhEpo treatment or were TD (&gt;2 units/month) with serum Epo &gt;500mU/mL were eligible. Patients were stratified by serum Epo level and prior rhEpo (EA vs. darbepoetin vs. none) then randomized to treatment with LEN 10 mg/d x21d q4wk (Arm A) or LEN + EA 60,000U SC/wk (Arm B). The primary endpoint was major erythroid response (MER) at week 16 which was defined according to transfusion status at baseline: (1) achievement of RBC-TI for ≥ 8 consecutive weeks AND a sustained ≥1 g/dL hemoglobin rise compared to mean pre-transfusion baseline value in TD patients; and (2) a &gt;2 g/dL rise in hemoglobin without transfusion for ≥ 8 consecutive weeks in non-TD patients (&lt;4U RBC/8 wks). Arm A non-responders were offered cross-over to combined therapy. Results: Among 205 patients randomized, 14 were excluded from the primary analysis due to a 4 month interruption in drug supply. Among the 195 evaluable patients, 96 were assigned to Arm A and 99 to Arm B. Baseline characteristics were well balanced between arms with 85% of patients heavily TD, receiving a median of 4 units/8 weeks. Overall, 93% of patients received prior treatment with Epo and 18% azanucleosides. In an intent to treat analysis, 28/99 patients (28.3%) in Arm B achieved MER compared to 11/96 (11.5%) in Arm A (P=0.004). Among 136 patients who completed 16 weeks of study treatment, 28/72 (38.9%) and 10/64 (15.6%) achieved MER, respectively (P=0.004). Forty-four Arm A non-responders crossed over to combination-therapy with 11 patients (25%) experiencing a MER. Multivariable logistic regression analysis identified only treatment with LEN + EA as an independent covariate for erythroid response (P=0.01). Responses were durable with MER median duration of 23.8 months in Arm B compared to 13 months in Arm A. There was no significant difference in the frequency or distribution of &gt;Grade 3, non-hematologic adverse events between treatment arms. Two patients progressed to AML while on study (Arm A), and no thromboembolic events were reported. Conclusions: LEN restores sensitivity to rhEpo in otherwise refractory, LR-non-del(5q) MDS patients to yield a significantly higher frequency of durable major erythroid responses compared to LEN alone. The addition of LEN to EA treatment is an effective strategy for the management of Epo-refractory patients with a potential duration of benefit extending to years.

Abstract Chronic idiopathic myelofibrosis (MF) is a clonal hematopoietic disorder that leads to progressive marrow fibrosis and peripheral cytopenias. Very little is known about the role of aberrant DNA methylation in the pathobiology of this disease. Whole genome methylation was analyzed by a recently described novel method, the HELP assay (HpaII tiny fragment Enrichment by Ligation-mediated PCR; Khulan et al, Genome Res. 2006 Aug;16(8)) that uses differential methylation specific restriction digestion by HpaII and MspI followed by amplification, two color labeling and cohybridization to quantitatively determine individual promoter methylation. A whole genome human promoter array (Nimblegen) was used to determine the level of methylation of 25626 gene promoters by calculating HpaII/MspI cut fragment intensity ratio. Peripheral blood leucocytes from 9 patients with IMF were compared to 9 age-matched normal and anemic controls. Gene expression analysis was performed using 37K oligo maskless arrays using cDNA from the same samples. Methylation analysis showed that myelofibrosis samples clustered separately from normal and anemic controls when grouped by unsupervised clustering based on Pearson’s correlation coefficient. On the other hand, global gene expression demonstrated no clear cut differences between myelofibrosis and control samples suggesting that methylation profiling has greater discriminatory power when compared to conventional gene expression profiling. A high correlation (r=0.88–0.96) was observed between whole genome methylation profiles of matched sets of bone marrow and peripheral blood leucocyte samples from selected patients demonstrating that peripheral blood leucocytes can act as a valid surrogates for epigenomic analysis. Further analysis showed that genes aberrantly methylated in all myelofibrosis samples included v-myc, histone 2A, TNF, TNF Receptor1, FGF14 and others. Functional pathway analysis by Ingenuity showed that pathways involved in Inflammation and Cell signaling were the most affected by epigenetic silencing. Most interestingly, a large proportion of gene promoters were also aberrantly hypomethylated. These included genes for chemokine CXCL13, APC, IL-3, STAT2 and others. The pathways most activated by hypomethylation were involved in hematopoiesis and cell growth and proliferation demonstrating the biological validity of our analysis. Thus, our data demonstrates that myelofibrosis is characterized by distinct epigenetic aberrations that are preserved in peripheral blood leucocytes. These can be the basis of future studies on pathogenesis and diagnosis for this disease and lead to translational studies with agents targeting DNA methylation.
