Smoldering Myeloma

8104 Background: Recent guidelines emphasize tailored follow-up and the need for clinical trials for high-risk smoldering myeloma (SMM). Emerging evidence from epidemiological studies suggests that immune-related conditions play a role in the causation of myeloma precursor disease (SMM and monoclonal gammopathy of undetermined significance; MGUS) and are of clinical importance for the risk of developing multiple myeloma. The aim of our study is to assess whether there is an altered biology in SMM/MGUS patients with preceding immune-related conditions. Methods: From our ongoing prospective SMM/MGUS natural history study, we evaluated 56 SMM and 60 MGUS patients. Information on autoimmunity was identified at baseline. All patients underwent extensive clinical and molecular characterization. At baseline, all patients underwent bone marrow biopsy evaluation using immunohistochemistry and multi-color flow cytometry of plasma cells. We assessed expression patterns of adverse plasma cell markers (CD56 and CD117), and applied risk models based on serum immune markers and bone marrow findings. Results: Among enrolled SMM and MGUS patients, 7 (12%) and 9 (15%) had a preceding autoimmune disorder. We found SMM patients with (vs. without) a preceding autoimmune disorder to have a substantially lower rate of CD56 (28% vs. 61%) and CD117 (28% vs. 61%) expressing plasma cells. When we compared the same markers in MGUS patients, CD56 and CD117 expression patterns were similar among patients with vs. without preceding autoimmunity (10% vs. 17%, and 50% vs. 48%). Using the Mayo Clinic risk model, none of the SMM patients with a preceding autoimmune disorder had high-risk features; in contrast, 3/41 (7%) of those without a preceding autoimmune disorder were high-risk SMM. Using the Mayo Clinic risk model, none of the MGUS patients were high-risk independent of autoimmune status. Conclusions: Our prospective clinical study found SMM patients with preceding immune-related conditions to have less adverse biology, supportive of epidemiological studies suggesting the risk of developing multiple myeloma is substantially lower in these patients.

Abstract The adage for smoldering myeloma (SMM) has been to observe without treatment, until criteria for active multiple myeloma were satisfied. Definitions and risk stratification models have become more sophisticated, with prognostication tailored to include high-risk cytogenetics as per the most recent International Myeloma Working Group 2020 risk model. Moreover, progress in defining genomic evolution and changes in the bone marrow microenvironment through the monoclonal continuum have given insight into the complexities underlying the different patterns of progression observed in SMM. Given recent data showing improved progression-free survival with early intervention in high-risk SMM, the current dilemma is focused on how these patients should be treated. This case-based article maps the significant advancements made in the diagnosis and risk stratification of SMM. Data from landmark clinical trials will also be discussed, and ongoing trials are summarized. Ultimately, we outline our approach to SMM and hope to impart to the reader a sound concept of the current clinical management of SMM.

Smoldering Myeloma

Over the last decade, two strategies have advanced the treatment of patients with multiple myeloma and precursor diseases. First, the definition has changed to include patients without end organ damage, who previously would not be treated. Second, there is widespread enthusiasm to treat high risk smoldering myeloma. In this commentary, we explore the evidence supporting these therapeutic expansions. While treating early adds cost and therapeutic burden, it remains unknown whether survival or health related quality of life is improved from early treatment. Herein, we consider the implications of diagnostic expansion in multiple myeloma.

Smoldering Myeloma

Background High risk smoldering multiple myeloma (HRSMM), defined as having immunoparesis and at least 95% abnormal plasma cells/all plasma cells by advanced flow cytometry, has a risk of progression to multiple myeloma of about 75% after 5 years of diagnosis. These patient have no symptoms and current standard is to follow them without treatment. Isatuximab is an IgG1 monoclonal antibody that binds to CD38 highly expressed in myeloma cells. Isatuximab has activity as monotherapy (overall response rate (ORR) 35%), with lenalidomide/dexamethasone (ORR 56%) and pomalidomide/dexamethasone (ORR 62%) in relapsed MM. We designed a phase II study to test the efficacy of isatuximab in high risk smoldering myeloma. Our study is registered in clinicaltrials.gov as NCT02960555. Methods The primary endpoint of the study is the ORR of isatuximab 20 mg/kg IV days 1, 8, 15, 22 cycle 1; days 1, 15 cycles 2-6 and day 1 cycles 7-30 in high risk smoldering myeloma. 24 patients were accrued in the first stage (of maximum 61 patients). Secondary endpoints are PFS, OS, clinical benefit rate (CBR). Exploratory endpoints are quality of life analysis (QoL), MRD, molecular/immune characterization using DNA/RNA sequencing of myeloma cells and the microenvironment before and after treatment. Results 24 patients with HRSMM were accrued from 02/08/2017 until 12/21/2018 (Table 1). All patients are evaluable for response. Best responses: ORR (≥PR) 15(62.5%), CR MRD- flow at 10-5 1 (5%), VGPR 4 (17%), PR 10 (42%), minor response (MR) 4 (18%), stable disease 5 (21%); CBR (≥MR) 79%. Median number of cycles received were 11.5 (range 6-30). Five patients have stopped treatment (one has completed the study, one with heavy history of smoking was diagnosed with squamous cell cancer of the tongue, one could no longer travel to treatments due to relocation, two progressed to active multiple myeloma after 16 and 6 cycles of treatment, respectively). There have been no deaths. DNA/RNA seq is ongoing for biomarkers of response. There were 5 grade 3 severe treatment-related adverse events (RAE) which resolved to baseline: dyspnea -related to infusion reaction (n=2), headache (n=1), ANC decrease (n=1), urinary tract infection (n=1). Most common grade 1-2 related adverse events (n): nausea (7), vomit (5), WBC decrease (3), diarrhea (3), fatigue (6), headache (4), mucositis (4), myalgia (4) and infusion reaction (3). In patients with available QoL functional scores (n=9 at baseline and n=7 after 6 months of therapy), isatuximab was effective in reducing their anxiety and worry of progression to multiple myeloma. Isatuximab also improved general QoL scores by the end of cycle 6 of treatment which were now comparable to those in the general population (Figure 1). Conclusion Isatuximab is very well tolerated, results in high response rates in HRSMM and has the potential to change the natural history of this disease. In ongoing QoL analysis, initial data shows improvement in QoL and decreased cancer worry after isatuximab treatment. Immune-genomic analysis is ongoing and may identify patients that benefit the most from treatment.

High Risk Screening

We provide our recommendations (not evidence based) for managing multiple myeloma patients during the pandemic of COVID-19. We do not recommend therapy for smoldering myeloma patients (standard or high risk). Screening for COVID-19 should be done in all patients before therapy. For standard-risk patients, we recommend the following: ixazomib, lenalidomide, and dexamethasone (IRd) (preferred), cyclophosphamide lenalidomide and dexamethasone (CRd), daratumumab lenalidomide and dexamethasone (DRd), lenalidomide, bortezomib, and dexamethasone (RVd), or cyclophosphamide, bortezomib, and dexamethasone (CyBorD). For high-risk patients we recommend carfilzomib, lenalidomide, and dexamethasone (KRd) (preferred) or RVd. Decreasing the dose of dexamethasone to 20 mg and giving bortezomib subcutaneously once a week is recommended. We recommend delaying autologous stem cell transplant (ASCT), unless the patient has high-risk disease that is not responding well, or if the patient has plasma cell leukemia (PCL). Testing for COVID-19 should be done before ASCT. If a patient achieves a very good partial response or better, doses and frequency of drug administration can be modified. After 10–12 cycles, lenalidomide maintenance is recommended for standard-risk patients and bortezomib or ixazomib are recommended for high-risk patients. Daratumumab-based regimens are recommended for relapsed patients. Routine ASCT is not recommended for relapse during the epidemic unless the patient has an aggressive relapse or secondary PCL. Patients on current maintenance should continue their therapy.

Abstract In the 1960s, Dr Jan Waldenström argued that patients who had monoclonal proteins without any symptoms or evidence of end-organ damage represented a benign monoclonal gammopathy. In 1978, Dr Robert Kyle introduced the concept of “monoclonal gammopathy of undetermined significance” (MGUS) given that, at diagnosis, it was not possible with available methods (ie, serum protein electrophoresis to define the concentration of M-proteins and microscopy to determine the plasma cell percentage in bone marrow aspirates) to determine which patients would ultimately progress to multiple myeloma. The application of low-input whole-genome sequencing (WGS) technology has circumvented previous problems related to volume of clonal plasma cells and contamination by normal plasma cells and allowed for the interrogation of the WGS landscape of MGUS. As discussed in this chapter, the distribution of genetic events reveals striking differences and the existence of 2 biologically and clinically distinct entities of asymptomatic monoclonal gammopathies. Thus, we already have genomic tools to identify “myeloma-defining genomic events,” and consequently, it is reasonable to consider updating our preferred terminologies. When the clinical field is ready to move forward, we should be able to consolidate current terminologies—from current 7 clinical categories: low-risk MGUS, intermediate-risk MGUS, high-risk MGUS, low-risk smoldering myeloma, intermediate-risk smoldering myeloma, high-risk smoldering myeloma, and multiple myeloma—to future 3 genomic-based categories: monoclonal gammopathy, early detection of multiple myeloma (in which myeloma-defining genomic events already have been acquired), and multiple myeloma (patients who are already progressing and clinically defined cases). Ongoing investigations will continue to advance the field.
