Nursing Considerations for Cytokine Release Syndrome in Relapsed/Refractory Multiple Myeloma: Experience with Teclistamab from the MajesTEC-1 Study.

OBJECTIVES: Cytokine release syndrome (CRS) is a systemic inflammatory response that is commonly observed as a class effect of T-cell-redirecting therapies. This article provides important practical guidance for nurses relating to the diagnosis, monitoring, and management of CRS in patients receiving teclistamab, based on experience from the MajesTEC-1 clinical trial and real-life nursing practice. METHODS: MajesTEC-1 is a phase 1/2 study of teclistamab in heavily pretreated patients with relapsed/refractory multiple myeloma. To mitigate the risk of high-grade CRS, patients were carefully monitored for early signs and symptoms of CRS (including fever, which must have fully resolved before teclistamab administration). RESULTS: A survey of nurses from several of the study sites provided additional real-life insights into nursing best practices for managing CRS from four academic institutions in three countries. CONCLUSIONS: In MajesTEC-1, 72% of patients treated with teclistamab experienced CRS, the majority of which was low grade. All cases resolved and none led to treatment discontinuation. Real-life supportive measures for CRS are generally aligned with those outlined in the study. IMPLICATIONS FOR NURSING PRACTICE: Because nurses are on the frontline of patient care, they play a crucial role in promptly recognizing the signs and symptoms of CRS and responding with timely and appropriate supportive treatment. This review provides important practical guidance for nurses on diagnosis, monitoring, and management of CRS in patients receiving teclistamab, based on experience from the MajesTEC-1 trial and real-life nursing practice.

Phase 1 study combining elotuzumab with autologous stem cell transplant and lenalidomide for multiple myeloma.

BACKGROUND: Autologous stem cell transplantation (ASCT) after induction therapy improves disease-free survival for patients with multiple myeloma (MM). While the goal of ASCT is to render a minimal disease state, it is also associated with eradication of immunosuppressive cells, and we hypothesize that early introduction of immunotherapy post-ASCT may provide a window of opportunity to boost treatment efficacy. METHODS: We conducted a phase 1 clinical trial to investigate the application of autologous lymphocyte infusion and anti-SLAMF7 monoclonal antibody, elotuzumab, after ASCT in patients with newly diagnosed MM previously treated with induction therapy. In addition to CD34+ stem cells, peripheral blood mononuclear cells were harvested prior to transplant and infused on day 3 after stem cell infusion to accelerate immune reconstitution and provide autologous natural killer (NK) cells that are essential to the mechanism of elotuzumab. Elotuzumab was administered starting on day 4 and then every 28 days after until 1 year post-ASCT. Cycles 4-12 were administered with standard-of-care lenalidomide maintenance. RESULTS: All subjects were evaluated for safety, and 13 of 15 subjects completed the treatment protocol. At 1 year post-ASCT, the disease status of enrolled subjects was as follows: five stringent complete responses, one complete response, six very good partial responses, one partial response, and two progressive diseases. The treatment plan was well tolerated, with most grade 3 and 4 AEs being expected hematologic toxicities associated with ASCT. Correlative analysis of the immune microenvironment demonstrated a trend toward reduced regulatory T cells during the first 3 months post-transplant followed by an increase in NK cells and monocytes in patients achieving a complete remission. CONCLUSIONS: This phase 1 clinical trial demonstrates that early introduction of immunotherapy after ASCT is well tolerated and shows promising disease control in patients with MM, accompanied by favorable changes in the immune microenvironment. TRIAL REGISTRATION NUMBER: NCT02655458.

Management of Adverse Events Associated with Pomalidomide-Based Combinations in Patients with Relapsed/Refractory Multiple Myeloma.

Multi-agent regimens incorporating immunomodulatory (IMiD®) agents such as thalidomide, lenalidomide, and pomalidomide have become the preferred standard of care for the treatment of patients with multiple myeloma (MM), resulting in improved survival outcomes. Currently, there are three IMiD agents approved for the treatment of MM: thalidomide, lenalidomide, and pomalidomide. Lenalidomide is commonly used to treat patients with newly diagnosed MM and as maintenance therapy following stem cell transplant or after disease relapse. Pomalidomide, the focus of this review, is approved in patients with relapsed/refractory MM (RRMM). Despite survival benefits, IMiD agents each have different safety profiles requiring consideration both prior to starting therapy and during treatment. Adverse event (AE) management is essential, not only to ensure treatment adherence and thus ensure optimal efficacy but also to maintain patient quality of life. Here, we discuss AEs associated with pomalidomide and present five clinically relevant hypothetical case studies in patients with RRMM to provide scenario-driven guidance regarding treatment selection and AE prevention and management in the clinical setting. Lastly, as new treatment approaches continue to be explored in MM, we also discuss novel cereblon E3 ligase modulator (CELMoD™) agents including iberdomide (CC-220) and mezigdomide (CC-92480).

Novel Treatments for Patients With Relapsed/Refractory Multiple Myeloma.

Therapeutic options for patients with multiple myeloma have multiplied in the past decade. However, multiple myeloma remains an incurable disease, and relapsed/refractory myeloma is characterized by genetic and cytogenetic alterations that drive resistance and result in progressively shorter durations of remission to each subsequent therapy. At JADPRO Live 2022, presenters discussed the multifactorial process for choosing the right therapy for a particular patient and strategies to manage unique treatment complications associated with novel treatment modalities used for patients with relapsed/refractory multiple myeloma.

A Focus on CAR T-Cell Therapy and Bispecific Antibodies in Multiple Myeloma.

Significant strides have been made in the management of patients living with myeloma. However, patients with multiply relapsed or refractory multiple myeloma (MM) have a shorter overall survival; therefore, new treatments with novel mechanisms of action are needed in this patient population. Patients with relapsing disease require a full restaging workup, including whole body imaging to evaluate for extramedullary disease and lytic bone lesions, as well as bone marrow biopsy with fluorescence in situ hybridization to determine if the patient has any new chromosomal changes that are present. Therapies utilizing the patient's immune cells, in particular T cells, provide a new option in relapsed/refractory myeloma. Treatment utilizing chimeric antigen receptor (CAR) T cells and/or bispecific antibody therapy provide excellent response rates. As such, advanced practitioners need to be aware of the potential toxicities associated with these newer treatments and how to manage them. This article will focus on the management of patients with relapsed and/or refractory disease who are undergoing treatment with either CAR T-cell therapy or bispecific T cell engager therapy.

Effect of t (11;14) Abnormality on Outcomes of Patients With Newly Diagnosed Multiple Myeloma in the Connect MM Registry.

BACKGROUND: The t (11;14) (q13;32) translocation [t (11;14)] is present in ∼20% of patients with newly diagnosed multiple myeloma (NDMM), but studies examining its prognostic ability have yielded divergent results, and data are lacking on outcomes from first-line therapy. PATIENTS AND METHODS: Data from the Connect MM Registry, a large US, multicenter, prospective observational cohort study of patients with NDMM were used to examine the effect of t (11;14) status on first-line therapy outcomes in the Overall population (n = 1574) and race groups (African American [AA] vs. non-African American [NAA]). RESULTS: Baseline characteristics were generally similar between patients with (n = 378) and without (n = 1196) t (11;14). Prevalence of t (11;14) was similar by race (AA, 27%; NAA, 24%). In the overall population, regardless of first-line therapy, t (11;14) status did not affect progression-free survival (hazard ratio, 1.02; P = 0.7675) or overall survival (hazard ratio, 0.99; P = .9417). AA patients with t (11;14) had higher likelihood of death (Nominal Cox regression P = .0298) vs. patients without t (11;14). CONCLUSIONS: Acknowledging observational study and inferential limitations, this exploratory analysis of a predominantly community-based population suggests that t (11;14) is a neutral prognostic factor in the general MM population but may be a negative factor for overall survival in AA patients.

Multiple Myeloma in Hispanics: Incidence, Characteristics, Survival, Results of Discovery, and Validation Using Real-World and Connect MM Registry Data.

BACKGROUND: Multiple myeloma (MM) in Hispanics has never been studied. We therefore sought to determine the clinical characteristics and overall survival in MM of Hispanics compared to non-Hispanic whites (NHW) and non-Hispanic blacks (NHB). PATIENTS AND METHODS: A single-center analysis of 939 patients diagnosed with MM from 2000 to 2017 with a large representation of NHB (n = 489), Hispanics (n = 281), and NHW (n = 169) was conducted to evaluate outcomes and disease characteristics. We used the Connect MM Registry, a large US multicenter prospective observational study with newly diagnosed MM patients, as a validation cohort. RESULTS: Hispanics had a higher incidence of MM compared to NHW. The median age at presentation was 5 years younger (median, 65 years) in Hispanics compared to NHW (median, 70 years), and patients were more likely to present with renal dysfunction (estimated glomerular filtration rate < 30 mL/min). Hispanics had a higher proportion of Revised International Staging System (R-ISS) stage I disease compared to NHW and NHB (P = .03), while there was no difference in cytogenetics between Hispanics and NHB/NHW. In the multivariate analysis, only high-risk disease and response to first-line therapy significantly affected survival. CONCLUSION: In this first and largest analysis of MM in Hispanics, we found that Hispanics present at a younger age, have a higher incidence of renal dysfunction, and have low R-ISS stage disease at presentation. With equal access to therapy, Hispanics have survival similar to NHW/NHB.

Integrating Touchscreen-Based Geriatric Assessment and Frailty Screening for Adults With Multiple Myeloma to Drive Personalized Treatment Decisions.

PURPOSE: Geriatric assessment (GA) results predict toxicity/survival in older adults, yet GA is not routinely used in care for patients with multiple myeloma (MM). We tested a tablet-based modified GA (mGA) providing real-time results to clinicians. METHODS: One hundred sixty-five patients with MM aged ≥ 65 years facing a treatment decision from 4 sites completed a tablet-based mGA with Katz Activities of Daily Living (ADL), Lawton Instrumental ADL, Charlson Comorbidity Index, and variables from the Cancer and Aging Research Group's Chemotherapy Toxicity Calculator. Providers reviewed the assessment results at the treatment visit. RESULTS: Patients were white (72%; n = 86), mean age was 72 years (range, 65-85 years), and averaged 7.71 minutes (range, 2-17 minutes) for survey completion. Providers averaged 3.2 minutes (range, 1-10 minutes) to review mGA results. Using International Myeloma Working Group frailty score, patients were fit (39%; n = 64), intermediate fit (33%; n = 55), or frail (28%; n = 46). Providers selected more aggressive treatments in 16.3% of patients and decreased treatment intensity in 34% of patients; treatment intensification was more common for fit patients and milder treatments for frail patients (χ2 = 20.02; P < .0001). Transplant eligibility significantly correlated with fit status and transplant ineligibility with frail status (P = .004). Outcomes on 144 patients 3 months post study visit showed 19.4% (n = 28) had grade ≥ 3 hematologic toxicities, 38.9% (n = 56) had dose modifications, and 18% (n = 26) had early therapy cessation. CONCLUSION: Limited patient time required for survey completion and provider time for results review show mGA can be easily incorporated into clinical workflow. Real-time mGA results indicating fit/frailty status influenced treatment decisions.

Multiple Myeloma: Detecting Genetic Changes Through Bone Marrow Biopsy and the Influence on Care.

Knowledge of genetic mutations and how these affect patient outcomes is rapidly expanding in the care of individuals diagnosed with multiple myeloma (MM). Genetic analysis of bone marrow biopsies now provides information about diagnosis,response to treatment, and prognosis. Oncology nurses need to understand the science and meaning of bone marrow biopsy reports, including the implications of genetic alterations and minimal residual disease. This will allow them to provide care, support, and education related to MM and its treatment to patients and their families.

Blood Transfusion Management and Transfusion-Related Outcomes in Daratumumab-Treated Patients With Relapsed or Refractory Multiple Myeloma.

INTRODUCTION: Daratumumab, a human CD38 monoclonal antibody approved for multiple myeloma (MM) treatment, binds red blood cells (RBCs), resulting in panagglutination in compatibility tests. Published mitigation methods avoid additional testing, ensuring timely release of blood products. Blood transfusion management and transfusion-related outcomes of daratumumab-treated patients in the SIRIUS study are reported, with emphasis on 2 clinical sites. PATIENTS AND METHODS: Patients had MM treated with ≥ 3 prior lines of therapy, including a proteasome inhibitor and an immunomodulatory drug, or were refractory to a proteasome inhibitor and an immunomodulatory drug. RBC typing and alloantibody screening were performed in gel cards. Antibody identification using RBC panels was performed on patients with positive antibody screens. Hematology panels and serum chemistry were analyzed ≤ 2 days before each daratumumab infusion and the first daratumumab dose within each treatment cycle, respectively. Pre- and posttransfusion hemoglobin values were analyzed retrospectively. RESULTS: At clinical cutoff, patients received 236 transfusions; 47 (37.9%) of 124 patients received 147 packed RBC transfusions, and 17 (13.7%) received 89 platelet transfusions. No hemolysis was reported, and 1 platelet transfusion reaction was observed. At Mount Sinai, no transfusion adverse events were observed, no new unexpected RBC alloantibodies were identified, and transfusions increased hemoglobin values (median, 1.2 g/dL). At Levine Cancer Institute, 6 of 7 patients responded to transfusions, with a median hemoglobin change of 1.7 g/dL. CONCLUSION: In SIRIUS, no RBC transfusion reactions, including hemolysis, were observed. Observations from Mount Sinai and Levine Cancer Institute confirm that transfusions may be administered safely to daratumumab-treated patients.

Distress, Fatigue, and Sexuality: Understanding and Treating Concerns and Symptoms in Patients With Multiple Myeloma 
.

BACKGROUND: The psychological needs of patients and caregivers may be inadvertently overlooked, contributing to the patient's distress and possibly compromising outcomes. Untreated, these psychological needs may impair the patient's ability to make decisions and adhere to treatment. 
. OBJECTIVES: This article aims to present consensus statements to guide oncology nurses in the recognition and management of distress, fatigue, and sexual dysfunction in patients with multiple myeloma (MM). 
. METHODS: Members of the International Myeloma Foundation Nursing Leadership Board reviewed the current literature and clinical experience regarding interventions related to distress, fatigue, and sexual dysfunction in patients with MM.
. FINDINGS: Ongoing patient education and attention to medical and psychological care is important to assess and address patients' needs, such as cancer-related fatigue, sexual dysfunction, and distress.

Immunotherapy in Multiple Myeloma.

OBJECTIVES: To review the use of monoclonal antibodies (mAbs) in the treatment of multiple myeloma (MM) and the management of most common side effects. DATA SOURCES: Review of journal articles related to mAbs in MM. CONCLUSION: The therapeutic options for MM have improved dramatically and the development of mAbs has been associated with improvement in clinical outcomes and favorable toxicity profiles. IMPLICATIONS FOR NURSING PRACTICE: With appropriate pre-medications and nursing management, mAbs are a well-tolerated treatment option for myeloma patients.

A phase 2 study of panobinostat with lenalidomide and weekly dexamethasone in myeloma.

Phase 3 studies combining histone deacetylase inhibitors with bortezomib were hampered by gastrointestinal (GI) intolerance, which was not observed when combined with immunomodulatory drugs. This study is a single-center phase 2 study of panobinostat with lenalidomide and dexamethasone (FRD). Twenty-seven relapsed multiple myeloma patients were enrolled. Twenty-two patients (81%) were lenalidomide refractory and 9 (33%), 14 (52%), and 7 (26%) were refractory to pomalidomide, bortezomib, and carfilzomib, respectively. High-risk molecular findings were present in 17 (63%) patients. Responses included 2 complete responses (CRs), 4 very good partial responses (VGPRs), 5 partial responses (PRs), and 9 minimal responses (MRs) for an overall response rate of 41%, clinical benefit rate of 74%, and a disease control rate of 96%. The median progression-free survival (PFS) was 7.1 months. In the 22 lenalidomide-refractory patients, there were 1 CR, 4 VGPRs, 3 PRs, and 7 MRs, with a median PFS of 6.5 months. Median overall survival was not reached. Grade 3/4 toxicities were primarily hematologic. Gene expression profiling of enrollment tumor samples revealed a set of 1989 genes associated with short (<90 days) PFS to therapy. MAGEA1 RNA and protein expression were correlated with short PFS, and laboratory studies demonstrated a role for MAGE-A in resistance to panobinostat-induced cell death. FRD demonstrates durable responses, even in high-risk, lenalidomide-refractory patients, indicating the essential role of panobinostat in attaining responses. MAGEA1 expression may represent a functional biomarker for resistance to panobinostat. In contrast to PANORAMA 1, there were no significant GI toxicities and primarily expected hematologic toxicities. This trial was registered at www.clinicaltrials.gov as #NCT00742027.

Lack of health maintenance examinations and risk in myeloma patients.

Health maintenance (HM) practices are essential to prevent illness, promote well-being, and maximize health. Patients with multiple myeloma (MM) are at increased risk for cardiovascular disease and cancers, yet, research on HM practices and preventative care of MM survivors has limited report. The study comprised a descriptive, correlational, and cross-sectional online survey design. Survey of patients with MM was carried out through the International Myeloma Foundation (IMF) and the Association of Cancer Online Resources (ACOR) e-mail list services. The members of the IMF and ACOR e-mail list services were surveyed, of which 237 patients responded. The modified Medical Expenditure Preventive Survey-Preventive Care questionnaire was used; it included items that ask patients regarding their healthcare practices that relate to dental care, cancer prevention, addiction, lifestyles, sensory screening, immunizations, cardiovascular, endocrine, psychosocial, and bone health. Descriptive statistics, Pearson's chi-square, and Spearman's rho correlation coefficient were obtained. In this study, men had statistically significant inferior global health maintenance scores than women (P = 0.002). Being employed (P = 0.054) and married or partnered (P = 0.017) were significantly correlated with better health maintenance patterns among male respondents. In contrast, no statistically significant correlations between sociodemographic factors and health maintenance patterns were found in women. Patients with MM, particularly men, require continued education and close monitoring of health maintenance practices. These findings are consistent with publications looking at gender disparities in healthcare utilization in the United States. Studies show that men, in general, are less likely to seek preventative healthcare screenings. Healthcare providers must incorporate health maintenance promotion during clinic visits.
