A subanalysis of the GIMEMA-MMY-3006 trial was performed to characterize treatment-emergent peripheral neuropathy (PN) in patients randomized to thalidomide-dexamethasone (TD) or bortezomib-TD (VTD) before and after double autologous transplantation (ASCT) for multiple myeloma (MM). A total of 236 patients randomized to VTD and 238 to TD were stratified according to the emergence of grade ≥2 PN. Gene expression profiles (GEP) of CD138+ plasma cells were analyzed in 120 VTD-treated patients. The incidence of grade ≥2 PN was 35% in the VTD arm and 10% in the TD arm (P<0.001). PN resolved in 88 and 95% of patients in VTD and TD groups, respectively. Rates of complete/near complete response, progression-free and overall survival were not adversely affected by emergence of grade ≥2 PN. Baseline characteristics were not risk factors for PN, while GEP analysis revealed the deregulated expression of genes implicated in cytoskeleton rearrangement, neurogenesis, and axonal guidance. In conclusion, in comparison with TD, incorporation of VTD into ASCT was associated with a higher incidence of PN which, however, was reversible in most of the patients and did not adversely affect their outcomes nor their ability to subsequently receive ASCT. GEP analysis suggests an interaction between myeloma genetic profiles and development of VTD-induced PN. © 2014 Wiley Periodicals, Inc.

In recent years, the treatment of multiple myeloma has undergone significant changes. The availability of novel agents bortezomib, thalidomide and lenalidomide considerably improved the outcome of patients. The advantages related to the use of novel agents have been shown in various studies in patients eligible and ineligible for transplant. In elderly patients, novel agents have also revolutionized the treatment paradigm and have replaced the traditional melphalan-prednisone regimen. A sequential approach consisting of an induction regimen associated with a high rate of complete response, followed by consolidation/maintenance therapy, induces a profound cytoreduction and delays relapse, thus improving survival. Patients older than 75 years or who are otherwise vulnerable are more susceptible to adverse events. In this setting, less toxic regimens and appropriate dose-reductions should be adopted. This article provides an overview of the main trials for transplant-ineligible multiple myeloma patients. Recommendations on how to manage unfit patients and treatment-related toxicities are also provided. © 2013 Springer Science+Business Media New York.

Novel agents in combination with melphalan and prednisone (MP) significantly improved progression-free survival (PFS) and overall survival (OS) in multiple myeloma (MM). Randomized trials comparing MP plus bortezomib (VMP) versus MP plus thalidomide (MPT) are lacking. Nine hundred and fifty-six elderly (>65 years) newly diagnosed MM patients from six European randomized trials were retrospectively analyzed and matched for age, albumin, and beta2-microglobulin at diagnosis, 296 patients were selected from the VMP groups, and 294 from MPT. Complete response rate was 21% in the VMP patients and 13% in the MPT patients (P=0.007). After a median follow-up of 34 months (range, 1-92), VMP significantly prolonged both PFS (median 32.5 vs. 22.9 months, HR 0.65; 95% CI 0.52-0.82; P<0.001) and OS (median 79.7 vs. 45.1 months, HR 0.44; 95% CI 0.32-0.59; P<0.001) in comparison with MPT. The benefit in terms of OS of the VMP group was quite similar among patients with different risk factors defined by sex, ISS, ECOG performance status, or serum creatinine but not among patients ≥75 years. Multivariate analysis confirmed that VMP was an independent predictor of longer PFS and OS. In a control-case matched analysis, PFS and OS were prolonged in patients who received VMP in comparison with those treated with MPT. © 2013 Wiley Periodicals, Inc.

We conducted a pooled analysis of 869 individual newly diagnosed elderly patient data from 3 prospective trials. At diagnosis, a geriatric assessment had been performed. An additive scoring system (range 0-5), based on age, comorbidities, and cognitive and physical conditions, was developed to identify 3 groups: fit (score = 0, 39%), intermediate fitness (score = 1,31%), and frail (score ≥2, 30%). The 3-year overall survivalwas 84%in fit, 76% in intermediate-fitness (hazard ratio [HR], 1.61; P = .042), and 57% in frail (HR, 3.57; P < .001) patients. Thecumulative incidence of grade ≥3 nonhematologic adverse events at 12 months was 22.2%in fit, 26.4%in intermediate-fitness (HR, 1.23; P = .217), and 34.0%in frail (HR, 1.74; P < .001) patients. The cumulative incidence of treatment discontinuation at 12months was 16.5%in fit, 20.8%in intermediate-fitness (HR, 1.41; P = .052), and 31.2% in frail (HR, 2.21; P < .001) patients. Our frailty score predicts mortality and the risk of toxicity in elderly myeloma patients. The International Myeloma Working group proposes this score for the measurement of frailty in designing future clinical trials. These trials are registered at www.clinicaltrials.gov as #NCT01093136 (EMN01), #NCT01190787 (26866138MMY2069), and #NCT01346787 (IST-CAR-506).

The combination of melphalan, prednisone and thalidomide (MPT) has demonstrated efficacy and acceptable toxicity in newly diagnosed and relapsed/refractory patients with multiple myeloma (MM). Panobinostat is a potent oral pan-deacetylase inhibitor (pan-DACi). In preclinical and clinical studies, panobinostat showed good anti-myeloma activity in combination with several agents. This phase II study evaluated the combination of a fixed dose of MPT with escalating doses of panobinostat (three times weekly for 3 weeks, followed by a 9-day rest period) in relapsed/refractory MM. We used a two-stage design to determine whether the combination was safe and effective. At least a partial response was observed in 38.5% of patients. The maximum tolerated dose of panobinostat in combination with MPT could not be determined due to the high rate of dose-limiting toxicities experienced with panobinostat at doses of 10 and 15 mg. The most common grade 3/4 adverse events were neutropenia (71%) and thrombocytopenia (35.5%). In conclusion, MPT in combination with panobinostat three times weekly for 3 weeks followed by a 9-day rest period is not well tolerated in patients with relapsed/refractory MM. Future studies should evaluate alternative dose schedules of panobinostat. © 2012 Informa UK, Ltd.
