ABSTRACTPrognosis of multiple myeloma (MM) has improved during the past two decades. This has been attributed to the better understanding of the biology of disease leading to introduction of two new classes of molecules, namely immune-modulators (e.g. thalidomide, lenalidomide), and proteasome inhibitors (e.g. bortezomib), use of high dose chemotherapy and autologous stem cell transplantation (ASCT) and better supportive care. Current management of myeloma for young patients (≤65 years) includes initial induction therapy followed by consolidation with ASCT followed by maintenance therapy with low dose thalidomide or lenalidomide or bortezomib for 1-2 years.The choice of initial therapy for patients of MM is based upon their eligibility for ASCT which in turn is based on their age and major co-morbid conditions pertaining to cardiac and renal systems. Patients who are ≤65 years of age (or 65 to 70 years) with no major co-morbid conditions are considered potential candidates for ASCT. Four cycles of induction therapy are administered; a combination of 3 drugs (bortezomib, thalidomide, and dexamethasone (BTD) or bortezomib, lenalidomide, and dexamethasone (BLD) or bortezomib, cyclophosphamide and dexamethasone (BCD) is associated with higher complete response (CR) (approx. 30-40%) and very good partial response (VGPR) and better progression free survival (PFS). Further consolidation with ASCT results in CR rates of 50%–70%; patients who achieve CR, have improved event-free and overall survival. Our initial experience with 225 ASCT supports these observations.It is now possible to individualize therapy in a given patient. For example, for patients with renal failure (present in 20-30% of patients at diagnosis) ––bortezomib, dexamethasone and/or doxorubicin combination could be an option; for patients with pre-existing peripheral neuropathy––lenalidomide and dexamethasone is preferred; for patients at high risk of venous thrombo-embolism bortezomib- based regimens can be used safely. Treatment with bortezomib or bortezomib + lenalidomide for patients with poor cytogenetics (chromosome deletion t(4;14), t(14;16), 17p–) appears to result in an outcome similar to that in patients without these abnormalities.In conclusion, from being incurable, myeloma is now a chronic illness. Along with earlier diagnosis, improved treatment and better management of complications have resulted in longer disease control and survival with a better quality of life. Novel agents have provided an opportunity to tailor therapy in an individual patient. Further research is needed to improve outcome for patients who fail to achieve complete response, those with ISS stage III, and extra-medullary disease. Availability of oral proteasome inhibitors and monoclonal antibodies (e.g. IL-6 receptor) are likely to expand choice of agents for maintenance therapy in future.

First Relapse

Autologous stem-cell transplantation (ASCT) remains an integral part of treatment for previously untreated, and may have value in the treatment of relapsed patients with, multiple myeloma (MM). The addition of novel agents like immunomodulators and proteasome inhibitors as induction therapy before and as consolidation/maintenance therapy after ASCT has led to an improvement in complete response (CR) rates, progression-free survival (PFS) and overall survival (OS). With advances in supportive care, older patients and patients with renal insufficiency are now able to safely undergo the procedure. The data concerning the timing of ASCT (early in the disease course or at first relapse), single versus tandem (double) ASCT and the role and duration of consolidation and maintenance therapy post ASCT remain conflicting. This review aims to discuss the evolution of stem-cell transplant over the past 3 decades and its current role in the context of newer, safer and more effective therapeutic agents.

Abstract An otherwise healthy 60-year-old male was diagnosed with stage II multiple myeloma by the International Staging System characterized by anemia, diffuse lytic bone lesions, IgG kappa paraproteinemia, 45% bone marrow plasmacytosis and the t(4;14) by FISH and conventional cytogenetics. The patient had a very good partial remission with initial induction therapy consisting of four 3-week cycles of bortezomib 1.3 mg/m2 IV on days 1, 4, 8, and 11 plus dexamethasone 40 mg days 1-4 (all cycles), followed by a cyclophosphamide and G-CSF mobilized melphalan 200 mg/m2 autologous stem cell transplantation (ASCT) and experienced minimal side effects. He is doing well 60 days post-ASCT and is in a near complete remission. His oncologist recommends maintenance therapy with lenalidomide or bortezomib, but the patient is concerned about the increased risk of developing a secondary malignancy (SM), and because he has had such an encouraging response to induction therapy, he wonders if he could remain off therapy.

Abstract One potential approach to improve the results of autologous stem cell transplantation (ASCT) in multiple myeloma (MM) involves the use of more potent induction regimens; the achievement of deeper remission pre-ASCT should translate into longer progression-free (PFS) and overall survival (OS). To evaluate this hypothesis, we assessed the influence of the percent reduction in serum monoclonal protein (M protein) pre-ASCT in patients (pts) treated with dexamethasone-based regimens (most often VAD) on the best response, PFS and OS achieved after ASCT. Between 2000–2006, 376 pts with IgG (267) or IgA (109) non-progressive MM underwent ASCT. Median age was 59 (21–73) yrs; 60% were male. The median hemoglobin at diagnosis was 103 g/L, creatinine 98 μmol/L, β2-microglobulin 241 nmol/L and albumin 35 g/L. Maintenance therapy was given to 84 (22%) after ASCT and consisted of corticosteroids in 29, thalidomide in 10, both in 41 and other regimens in 4 pts. Patients were divided into 4 groups based on the per cent reduction in M protein after induction therapy: group A, ≥ 99%; group B, 90–98%; group C, 50–89%; group D, < 50%. Post-ASCT responses included complete remission (CR), very good partial remission (VGPR) (≥ 90% reduction in M protein), PR (≥ 50% reduction) and stable disease (SD). Median follow-up from diagnosis is 37.4 mos and from ASCT 24.1 mos. For all pts, the median OS from diagnosis is 90.8 mos (95% CI 73.9–129.1 mos) and from ASCT 63.9 mos (95% CI 50.8–69.4 mos), while the median PFS from ASCT is 21.3 mos (95% CI 19.1–23.3 mos). Maintenance therapy had no significant effect on PFS (p=0.49) or OS (p=0.59). The post-ASCT results in evaluable patients according to the percent reduction in M protein after induction therapy are summarized below. We conclude: High-grade remissions after dexamethasone-based induction therapy are uncommon, with only 2% achieving ≥ 99% and 13% achieving 90–98% reduction in serum M protein; post-ASCT CR and VGPR rates were higher in these 2 groups; there was no significant difference in PFS or OS-based on protein response prior to transplant; whether newer induction regimens, which incorporate novel agents and which produce more CRs and VGPRs before ASCT, will confer better PFS and OS post-ASCT will be of great interest.

Abstract Background: Three drug combinations are the standard treatment for newly diagnosed multiple myeloma (NDMM). However, induction, consolidation, and maintenance therapy have not been standardized in Japan. Therefore, in this single arm Phase II study, we evaluated bortezomib-based induction, autologous stem cell transplantation (ASCT), bortezomib-based consolidation, and bortezomib maintenance in transplant eligible NDMM patients and assessed clinical outcomes as well as the minimal residual disease (MRD) status. Methods: Patients received four cycles of CyBorD induction therapy with bortezomib 1.3 mg/m2 and cyclophosphamide 300 mg/m2 on day 1, 8, 15, and 22 and dexamethasone 40 mg on day 1-3, 8-10, 15-17, and 22-24 for the first two cycles and day 1, 8, 15, and 22 for the last two cycles of four 28-day cycles. Peripheral blood stem cells were collected after cyclophosphamide 2 g/m2 for 2 days, which was followed by melphalan 200 mg/m2 and ASCT. Three months after ASCT, patients received consolidation treatment with three cycles of CyBorD identical to the last two cycles of the induction therapy followed by maintenance therapy with bortezomib 1.3 mg/m2 on day 1 and 15 of a 28-day cycle, for 24 months. The primary end-point was the complete response (CR) rate after consolidation therapy and assessed as an interim analysis. Responses were assessed according to the International Myeloma Working Group (IMWG) criteria. MRD was assessed using an allele-specific oligonucleotide real-time quantitative polymerase chain reaction (qPCR). The toxicity was evaluated according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE). Results: From August 2013 to May 2016, 42 (25 male and 17 female) patients with a median age of 58 (range 42-65) years with NDMM were found eligible and enrolled in 15 centers in Japan. The International Staging System (ISS) values were 1 in 17 (40%), 2 in 20 (48%), and 3 in 5 patients (12%). Adverse cytogenetics of 17p deletion, t(4;14), and t(14;16) were observed in 20%, 18%, and 3% of the evaluable patients, respectively. Following four induction cycles of CyBorD, the overall response rate (ORR) was obtained in 71% of patients, including a CR/sCR of 10% and very good partial response (VGPR) of 26%. One of the evaluable 11 patients showed MRD negativity after induction therapy. Four patients discontinued the protocol during the induction therapy because of grade 4 interstitial pneumonia (n = 2), prolonged grade 3 drug eruption (n = 1), and grade 1 delirium (n = 1). Four patients discontinued the protocol due to doctor judgement (inadequate efficacy, n = 2; repetitive infection, n = 1; grade 3 neutropenia, n = 1). A total of 26 of the 42 patients completed ASCT following the protocol and 18 achieved VGPR/CR, including CR in 10 patients. Three of the evaluable 10 patients showed MRD negativity after ASCT. The 2-year overall and progression-free survival rates were 93% (95% confidence interval [CI], 76%-98%) and 81% (95% CI, 51%-94%), respectively (Figure 1). Conclusions: CyBorD with ASCT for NDMM resulted in relatively high CR rates in the investigated Japanese population, although a relatively high incidence of discontinuation of therapy was observed. Dose and schedule modification of induction therapy may be necessary in Japanese populations. Clinical trial information: UMIN000010542. Figure 1. Figure 1.

Abstract Background Induction therapy of multiple myeloma patients prior to autologous stem cell transplantation has changed from conventional chemotherapy to treatment based on proteasome inhibitors or immunomodulatory drugs. We used flow cytometry to analyze total monocyte and monocyte subset (classical, intermediate and non-classical monocytes) peripheral blood levels before and following auto-transplantation for a consecutive group of myeloma patients who had received the presently used induction therapy. Results The patients showed normal total monocyte concentrations after induction/stem cell mobilization, but the concentrations of classical monocytes were increased compared with healthy controls. Melphalan conditioning reduced the levels of total CD14+ as well as classical and non-classical monocytes, whereas intermediate monocytes were not affected. Thus, melphalan has a non-random effect on monocyte subsets. Melphalan had a stronger effect on total and classical monocyte concentrations for those patients who had received induction therapy including immunomodulatory drugs. Total monocytes and monocyte subset concentrations decreased during the period of pancytopenia, but monocyte reconstitution occurred before hematopoietic reconstitution. However, the fractions of various monocyte subsets varied considerably between patients. Conclusions The total level of circulating monocytes is normalized early after auto-transplantation for multiple myeloma, but pre- and post-transplant levels of various monocyte subsets show considerable variation between patients.
