Avaliação de risco em mioloma múltiplo: resultados preliminares do grupo brasileiro de estudos de mieloma

The Durie/Salmon staging system continues to be used worldwide in patients with multiple myeloma. However, in recent years, new systems have been proposed. The International Myeloma Working Group performed a retrospective study with 11,179 patients and proposed an "International Staging System" utilizing serum levels of â2 microglobulin and albumin. In addition, current research has focused on the usefulness of cytogenetic and molecular data as prognostic factors. These data suggest that these parameters are powerful discriminators of a poor prognostic group of myeloma patients. Indeed, these prognostic indexes have been utilized in clinical trials, with interesting and encouraging results.O esquema de Durie / Salmon continua a ser utilizado para estadiar os pacientes com mieloma múltiplo.

Autologous stem cell transplantation improves quality of life in economically challenged, Brazilian multiple myeloma patients

OBJECTIVES: 1) To characterize the impact of multiple myeloma on the quality of life of patients treated in two public institutions in São Paulo State, Brazil, using a generic Short Form 36 Health Survey and a questionnaire specific for oncologic patients (QLQ-C30) upon diagnosis, after the clinical treatment, and at day +100 after autologous stem cell transplantation; 2) to evaluate whether autologous stem cell transplantation can improve the quality of life of our economically challenged population aside from providing a clinical benefit and disease control. METHODS: We evaluated 49 patients with multiple myeloma (a total of 70 interviews) using the two questionnaires. The scores upon diagnosis, post-treatment/pre-autologous stem cell transplantation, and at D+100 were compared using ANOVA (a comparison of the three groups), post hoc tests (two-by-two comparisons of the three groups), and paired t-tests (the same case at two different times). RESULTS: Of the included patients, 87.8% had a family budget under US $600 (economic class C, D, or E) per month. The generic Short Form 36 Health Survey questionnaire demonstrated that physical function, role-physical, and bodily pain indices were statistically different across all three groups, favoring the D+100 autologous stem cell transplantation group (ANOVA). The questionnaire specific for oncologic patients, the QLQ-C30 questionnaire, confirmed what had been demonstrated by the Short Form 36 Health Survey with respect to physical function and bodily pain, with improvements in role functioning, fatigue, and lack of appetite and constipation, favoring the D+100 autologous stem cell transplant group (ANOVA). The post hoc tests and paired t-tests confirmed a better outcome after autologous stem cell transplantation CONCLUSION: The questionnaire specific for cancer patients seems to be more informative than the generic Short Form 36 Health Survey questionnaire and reflects the real benefit of autologous stem cell transplantation in the quality of life of multiple myeloma patients in two public Brazilian institutions that provide assistance for economically challenged patients.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Federal de São Paulo (UNIFESP)Santa Casa de Misericórdia de São Paulo Faculdade de Ciências MédicasUniversidade Federal de São Paulo (UNIFESP) Departamento de MedicinaCedars-Sinai Outpatient Cancer CenterUNIFESP, Depto. de MedicinaSciEL

Isatuximab as monotherapy and combined with dexamethasone in patients with relapsed/refractory multiple myeloma

This phase 2 study evaluated isatuximab as monotherapy or combined with dexamethasone in relapsed/refractory multiple myeloma (RRMM). Patients had RRMM refractory to an immunomodulatory drug (IMiD) and a proteasome inhibitor (PI) or had received >= 3 prior lines of therapy incorporating an IMiD and PI. Patients received isatuximab either as monotherapy (20 mg/kg on days 1, 8, 15, and 22 [once weekly] of cycle 1 followed by 20 mg/kg on days 1 and 15 of subsequent cycles; Isa group) or in combination with dexamethasone (40 mg/d [20 mg/d in patients aged >= 75 years] once weekly; Isa-dex group). Treated patients (N=164) had received a median of 4 (range, 2-10) prior treatment lines. Patients received a median of 5 (1-24) and 7 (1-22) treatment cycles; at data cutoff, 13 (11.9%) of 109 and 15 (27.3%) of 55 patients remained on treatment in the Isa and Isa-dex arms, respectively. Overall response rate (primary efficacy end point) was 23.9% in the Isa arm and 43.6% in the Isa-dex arm (odds ratio, 0.405; 95% confidence interval, 0.192-0.859; P=.008). Median progression-free survival and overall survival were 4.9 and 18.9 months for Isa, and 10.2 and 17.3 months for Isa-dex. Infusion reactions (mostly grade 1/2) and hematologic abnormalities were the most common adverse events. There was a similar incidence of grade 3 or higher infections in both groups (22.0% and 21.8%). In conclusion, addition of dexamethasone to isatuximab increased response rates and survival outcomes with no detrimental effect on safety.Peer reviewe

Isatuximab in combination with lenalidomide and dexamethasone in patients with high-risk smoldering multiple myeloma: Updated safety run-in results from the randomized phase 3 ithaca study

Background: Results from a randomized, Phase 3 study by the Spanish Myeloma Group (PETHEMA/GEM) previously showed that treatment with lenalidomide plus dexamethasone (Rd) may delay progression to active disease in patients (pts) with high-risk smoldering multiple myeloma (SMM), compared with observation. To further improve outcomes, addition of the anti-CD38 antibody isatuximab (Isa) to lenalidomide and dexamethasone (Isa-Rd) for the treatment of pts with high-risk SMM is being evaluated in the ongoing, randomized, multi-center, Phase 3 ITHACA study (NCT04270409). Initial findings from the safety run-in analysis of this trial have shown a manageable safety profile and encouraging, preliminary anti-myeloma activity. We now report updated safety and efficacy results from the safety run-in part of ITHACA at a median follow-up of 19.4 months. Methods: Pts were included in the study if they had been diagnosed within 5 years with SMM (per the International Myeloma Working Group [IMWG] criteria) and had high-risk SMM according to the Mayo '20-2-20' and/or updated PETHEMA model criteria. Pts who had received prior anti-myeloma treatment were not eligible. Enrolled pts received Isa 10 mg/kg IV on day (D) 1, 8, 15, and 22 in cycle (C) 1, D1 and D15 C2-12, D1 C13-36; plus R D1-21 (25 mg C1-9; 10 mg C10-24) and d weekly (40 mg, 20 mg for ≥75 yr-old pts C1-9; 20 mg C10-24). Cycle duration was 28 days. Safety evaluations included treatment-emergent AEs (TEAEs)/serious AEs and laboratory parameters, graded by NCI-CTCAE v5.0. Response was determined by IMWG criteria (2016). Mandatory imaging by MRI and/or low-dose whole-body CT/PET-CT, and assessments of minimal residual disease (MRD, by next-generation sequencing in pts with very good partial response [VGPR] or better), were performed at protocol-defined time points. The primary study objective for the safety run-in was to confirm the recommended dose of Isa in combination with Rd. Overall response rate (ORR) and MRD negativity rate at 10-5 sensitivity were included as secondary endpoints.Sanof

Ixazomib-lenalidomide-dexamethasone in routine clinical practice: Effectiveness in relapsed/refractory multiple myeloma

[Aim]: To evaluate the effectiveness and safety of ixazomib-lenalidomide-dexamethasone (IRd) in relapsed/refractory multiple myeloma in routine clinical practice. Patients & methods: Patient-level data from the global, observational INSIGHT MM and the Czech Registry of Monoclonal Gammopathies were integrated and analyzed.[Results]: At data cut-off, 263 patients from 13 countries were included. Median time from diagnosis to start of IRd was 35.8 months; median duration of follow-up was 14.8 months. Overall response rate was 73%, median progression-free survival, 21.2 months and time-to-next therapy, 33.0 months. Ixazomib/lenalidomide dose reductions were required in 17%/36% of patients; 32%/30% of patients discontinued ixazomib/lenalidomide due to adverse events.[Conclusion]: The effectiveness and safety of IRd in routine clinical practice are comparable to those reported in TOURMALINE-MM1.This work was supported by Millennium Pharmaceuticals, Inc., Cambridge, MA, USA, a wholly owned subsidiary of Takeda Pharmaceutical Company Limited

Thalidomide plus dexamethasone as a maintenance therapy after autologous hematopoietic stem cell transplantation improves progression-free survival in multiple myeloma

Despite the good response of stem cell transplant (SCT) in the treatment of multiple myeloma (MM), most patients relapse or do not achieve complete remission, suggesting that additional treatment is needed. We assessed the impact of thalidomide in maintenance after SCT in untreated patients with MM. A hundred and eight patients (<70 years old) were randomized to receive maintenance with dexamethasone (arm A; n = 52) or dexamethasone with thalidomide (arm B; n = 56; 200 mg daily) for 12 months or until disease progression. After a median follow-up of 27 months, an intention to treat analysis showed a 2-year progression-free survival (PFS) of 30% in arm A (95% CI 2238) and 64% in arm B (95% CI 5771; P = 0.002), with median PFS of 19 months and 36 months, respectively. In patients who did not achieve at least a very good partial response, the PFS at 2 years was significantly higher when in use of thalidomide (19 vs. 59%; P = 0.002). Overall survival at 2 years was not significantly improved (70 vs. 85% in arm A and arm B, respectively; P = 0.27). The addition of thalidomide to dexamethasone as maintenance improved the PFS mainly in patients who did not respond to treatment after SCT. Am. J. Hematol.

INSIGHT MM: a large, global, prospective, non-interventional, real-world study of patients with multiple myeloma

With the introduction of new drugs with different mechanisms of action, multiple myeloma (MM) patients’ outcomes have improved. However, the efficacy seen in clinical trials is often not seen in real-world settings and data on the effectiveness of MM therapies are needed. INSIGHT MM is a prospective, global, non-interventional, observational study that is enrolling approximately 4200 patients with newly diagnosed or relapsed/refractory MM, making it the largest study of its kind to date. The study aims to describe contemporary, real-world patterns of patient characteristics, clinical disease presentation, therapies chosen, clinical outcomes (response, treatment duration, time-to-next-therapy, progression-free and overall survival), safety, healthcare resource utilization and quality of life. One interim analysis has been conducted to date; current accrual is approximately 3094 patients
