Abstract Abstract 4142 Introduction: High dose chemotherapy combined with autologous stem cell transplantation (ASCT) as opposed to conventional chemotherapy improved progression free survival (PFS) and overall survival (OS) in multiple myeloma (MM) and is currently the standard of care for newly diagnosed MM patients less than 65 years old. Over the last decade, novel agents such as lenalidomide or bortezomib have dramatically improved MM outcomes with similar response rates as ASCT and the role of upfront ASCT has become more controversial. Therefore the goal of this randomized clinical trial is to determine the role of upfront ASCT in newly diagnosed myeloma patients receiving novel agent lenalidomide and low-dose dexamethasone induction. Methods: Patients aged ≥18 years with newly confirmed, measurable MM in stage 2 and 3 (Salmon Durie) and meeting CRAB criteria were enrolled. Patients were randomized to transplant (Arm A) or to non-transplant (Arm B). Patients in Arm A received 4 cycles of lenalidomide (25mg days 1 – 21) plus low-dose dexamethasone (40mg days 1,8,15,22) followed by ASCT conditioned with 200 mg/m2 melphalan (LD+ASCT); Arm B patients received 8 cycles of lenalidomide plus low-dose dexamethasone (LD alone). Both arms received stem cell collection after 4 cycles of therapy if patients achieved at least a partial remission (PR). Patients with stable disease (SD) or progressive disease (PD) went off study. The primary objective was to compare best response. The secondary endpoints included duration of response (DOR), progression free survival (PFS), overall survival (OS) and evaluation of secondary malignancies in both arms. Results: From February 2008 to May 2011, 44 patients with newly diagnosed MM were randomized. The patient characteristics were as follow: median age of the patients was 61.7 years (range 48∼75), 45.5% female and 55.5% male patients, ISS stage I 31%, II 51% and III 18%. 40 patients were eligible for evaluation and 20 patients were randomized to Arm A or Arm B, respectively. The data were analyzed according to latest IMWG response criteria (Blood. 2011 May 5;117(18):4691–5). In an intention to treat analysis, patients in Arm A (LD + ASCT), achieved a 100% Overall Response Rate (ORR) with 40% PR (n=8) and 60% Very Good Partial Response (VGPR) (n=12). In Arm B (LD only) the ORR was 75% (n=15), including 15% CR (n=3), 35% VGPR (n=7), 25% PR (n=5), 20% SD (n=4) and 5% PD (n=1). The ORR was significantly superior in the LD+ASCT group compared to LD alone (p=0.047). After a median follow-up of 25.3 months, 17 patients have PD (8 in LD+ASCT and 9 in LD alone), 6 have died (1 in LD+ASCT and 5 in LD alone). DOR, PFS and OS were not significantly different in both groups. OS showed a trend to be superior in patients treated with LD+ASCT (p=0.08). (Table 1). One patient in the LD+ASCT arm developed MDS 13 months after start of therapy. Conclusion: Our interim analysis of an ongoing clinical study suggests that treatment of newly diagnosed MM patients with lenalidomide plus low-dose dexamethasone induction followed by upfront ASCT resulted in significantly improved ORR. There was no difference in terms of DOR or PFS with a trend of superior OS in the LD+ASCT group. The study requires careful interpretation based on the low patient number and relatively short follow up, but supports the continued role of upfront consolidative ASCT in newly diagnosed MM patients. The incidence of secondary malignancy was low with the development of 1 MDS. Updated data on response and overall survival will be available at the time of presentation.

Abstract Abstract 4554 High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is currently standard treatment for younger patients with multiple myeloma, resulting in improved survival and response rate compared to conventional chemotherapy. Disease relapse, however, remains almost inevitable and thus the role of two successive (tandem) autologous stem cell transplants has been evaluated in chemorefractory patients as a means of prolonging duration of disease response. We retrospectively analysed the results of nine patients with chemorefractory disease treated at a single UK institution who received tandem ASCT between January 1998 and February 2009. There were six men and three women. Median age at diagnosis was 56 years (range, 42–65 years). Paraprotein isotype was IgG in eight patients and IgA in one patient. Median serum paraprotein level was 41g/L (range 12–73g/L) at presentation. At time of 1st transplant six patients were in stable disease (SD) and three had evidence of progressive disease. Conditioning melphalan dose was 140mg/m2 in all but two patients who received 110mg/m2 and 200mg/m2. Median time between transplants was 3.7 months (range 2.3–6.4 months) with PR and SD being observed in 2/9 and 7/9 patients at time of 2nd transplant. None of the patients reached complete response (CR). One patient received melphalan 140mg/m2 prior to 2nd transplant. The remaining patients received melphalan 200mg/m2. Median follow up after tandem transplant was 54.3 months (range 15.6 –143.6 months). No treatment related mortality was reported. At the time of analysis, six patients were still alive and under follow up with an overall survival (OS) figure for the group of 52% at 10 years from diagnosis (Figure 1). Median progression free survival (PFS) was 20 months from 2nd transplant (range 6.7–62.6 months) (Figure 2). Tandem autologous stem cell transplant in chemorefractory patients has resulted in overall survival similar to autologous stem cell transplant in chemosensitive patients and should be considered in patients with chemorefractory disease.

Abstract The current standard of care for patients with newly diagnosed multiple myeloma (MM) aged less than 65 years is high-dose chemotherapy combined with autologous stem cell transplantation (ASCT) based on improved progression free survival (PFS) and overall survival (OS) compared with conventional chemotherapy. The introduction of novel agents, for example lenalidomide and bortezomib over the last decade, has substantially improved MM outcomes providing similar response rates to ASCT. As a consequence, the role of upfront ASCT has become more controversial. Therefore, this randomized clinical trial aims to determine the role of upfront ASCT in patients with newly diagnosed MM patients receiving lenalidomide and low-dose dexamethasone as induction therapy. Patients enrolled into the study were aged ≥18 years with newly diagnosed MM, transplant eligible, and meeting CRAB criteria. Patients were randomized to receive 4 cycles of lenalidomide (25 mg days 1–21) plus low-dose dexamethasone (40 mg days 1, 8, 15, 22) followed by ASCT conditioned with 200 mg/m2 melphalan (Arm A; LD+ASCT) or 8 cycles of lenalidomide plus low-dose dexamethasone (Arm B; LD alone). Both groups received lenalidomide maintenance therapy 10-15 mg for up to 2 years. Patients in both treatment arms received stem cell collection after 4 cycles of lenalidomide plus dexamethasone if at least a partial response was achieved. Patients with stable disease or progressive disease (PD) went off study. The primary objective was to compare the best response between patients treated with lenalidomide plus dexamethasone followed by ASCT and patients treated with lenalidomide plus dexamethasone alone. Secondary objectives were to compare the duration of response (DOR), PFS, and OS between the two treatment arms and to evaluate the secondary malignancies in both arms. Fifty patients with newly diagnosed MM were randomized between February 2008 and May 2013, and 47 patients were eligible for evaluation in this interim analysis; 25 patients randomized to Arm A (LD+ASCT) and 22 patients randomized to Arm B (LD alone). Overall, patients had a median age of 61.6 years (range 48–75), 60% were male, 34% ISS Stage I, 49% ISS Stage II, 17% ISS Stage III. The data were analyzed according to the IMWG response criteria (Blood. 2011 May 5;117(18):4691-5). In an intention-to-treat analysis, there was a trend towards improved overall response rate (ORR) in patients receiving LD+ASCT (96%) compared with patients receiving LD alone (77%; p=0.08) (Table 1). After a median follow-up of 36.8 months (range 1.1–62.7), the median DOR was 13.9 months (95% confidence interval [CI] 4.0–34.1) in the LD+ASCT group compared with 21.2 months (95% CI 11.0–22.9) in the LD group. Overall, 18 patients have PD (10 patients in the LD+ASCT arm and 8 patients in LD arm), and 8 patients have died (4 patents in the LD+ASCT arm and 4 patients in the LD arm). Median PFS for LD+ASCT versus LD was 17.0 months (95% CI 15.5–not estimable) versus 25.2 months (95% CI 9.0–not estimable; p=0.94). Median OS for LD+ASCT versus LD was 57.6 months (95% CI 48.0–not estimable) versus not reached (p=0.94). Two patients in the LD alone arm developed a secondary malignancy, including 1 patient with myelodysplastic syndrome (MDS) 13 months after the start of therapy. This interim analysis of an ongoing randomized clinical study comparing lenalidomide plus low-dose dexamethasone induction with and without upfront ASCT in patients with newly diagnosed MM suggests that addition of ASCT resulted in a trend towards improved ORR. This did not result in a significant difference in terms of PFS or OS between the two treatment arms. In contrast there was a trend of better DOR in the LD alone arm. The data show that LD alone can achieve similar results as LD+ASCT, however careful interpretation is required due to the low patient number and relatively short follow-up. The incidence of secondary malignancy was low, including the development of 1 MDS. Disclosures: Schecter: Celgene: Honoraria, Speakers Bureau. Mapara:Celgene: Research Funding, RO1 Other.

Purpose This analysis of the FIRST trial in patients with newly diagnosed multiple myeloma (MM) ineligible for stem-cell transplantation examined updated outcomes and impact of patient age. Patients and Methods Patients with untreated symptomatic MM were randomly assigned at a one-to-one-to-one ratio to lenalidomide plus low-dose dexamethasone until disease progression (Rd continuous), Rd for 72 weeks (18 cycles; Rd18), or melphalan, prednisone, and thalidomide (MPT; 72 weeks), stratified by age (≤ 75 v > 75 years), disease stage (International Staging System stage I/II v III), and country. The primary end point was progression-free survival. Rd continuous and MPT were primary comparators. Results Between August 21, 2008, and March 7, 2011, 1,623 patients were enrolled (Rd continuous, n = 535; Rd18, n = 541; MPT, n = 547), including 567 (35%) age older than 75 years. Higher rates of advanced-stage disease and renal impairment were observed in patients older than 75 versus 75 years of age or younger. Rd continuous reduced the risk of progression or death compared with MPT by 31% (hazard ratio [HR], 0.69; 95% CI, 0.59 to 0.80; P < .001) overall, 36% (HR, 0.64; 95% CI, 0.53 to 0.77; P < .001) in patients age 75 years or younger, and 20% (HR, 0.80; 95% CI, 0.62 to 1.03; P = .084) in those age older than 75 years. Median overall survival was longer with Rd continuous than with MPT, including a 14-month difference in patients age older than 75 years. Progression-free survival with Rd18 was similar to that with MPT, and overall survival with Rd18 was marginally inferior to that with Rd continuous. Rates of grade 3 to 4 treatment-emergent adverse events were similar for Rd continuous–treated patients age 75 years or older and those age older than 75 years; however, older patients had more frequent lenalidomide dose reductions. Conclusion Results support Rd continuous treatment as a new standard of care for stem-cell transplantation–ineligible patients with newly diagnosed MM of all ages.

AbstractThe clinical outcomes of 169 patients enrolled in the first clinical trial of thalidomide for advanced or refractory myeloma are updated. Seventeen patients remain alive and 10 are event-free, with a median follow-up of 9.2 years. According to multivariate analysis of pretreatment variables, cytogenetic abnormalities, present in 47% of patients within 3 months of enrollment, and λ light chain isotype both affected overall survival and event-free survival adversely. Forty percent of the 58 patients lacking these 2 unfavorable features, one-half of whom had no disease recurrence, survived at least 6 years, in contrast to fewer than 5% among those with 1 or 2 risk features (P < .001). Patients who had received cumulative thalidomide doses in excess of 42 g in the first 3 months enjoyed superior overall and event-free survival. The poor outcome associated with λ-type myeloma may relate to its overrepresentation in molecularly defined high-risk disease gleaned from studies in newly diagnosed myeloma.

Abstract Background: The role of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the setting of refractory multiple myeloma (MM) is still controversial. Although potentially curative in a subset of pts, concerns regarding treatment related mortality (TRM) and graft vs. host disease (GVHD) preclude its universal use. In this study, we evaluated the role of allo-HSCT for pts with relapsed MM. Methods: 110 consecutive pts with relapsed MM underwent allo-HSCT at our institution between 2000 and 2014. The primary objective was to assess progression-free (PFS) and overall survival (OS). Results: Median age at allo-HSCT was 54 (range, 32-71) years and median time from diagnosis to allo-HSCT was 35.7 (range, 8.6 to 228.8) months. Fifty-two (47%) and 49 (45%) pts had standard-risk (SR) and high-risk (HR) cytogenetics at the time of allo-HSCT, respectively. Pts received a median of 5 (range, 1-9) prior chemotherapy regimens and 99 (90%) pts had at least 1 (range, 0-3) prior auto-HSCTs. One hundred one (92%) pts received either a proteasome inhibitor (PI) or an immunomodulatory drug (IMiD) prior to allo-HSCT, with 65 (59%) receiving both. Sixty eight (62%) received allo-HSCT from matched related, 34 (31%) from matched unrelated, 5 (4%) from cord blood, and 3 (3%) from mismatched donors. Preparative regimen was fludarabine/melphalan-based in 88 (80%) and fludarabine/busulfan-based in 16 (15%) pts. Median time to neutrophil and platelet engraftment was 12 (range, 8-30) and 13 (range, 0-81) days, respectively. Ten pts died of non-relapse causes within 100 days (100-day TRM: 9%) and 21 (19%) within 1 year. Grade 1-4 acute GVHD was seen in 50 (45%) and cGVHD in 35 (32%) pts, respectively. Eighteen (16%) achieved a CR, 26 (23%) a VGPR and 38 (34%) achieved a PR, with an overall response rate of 73%. With a median follow up of 41.9 months (range, 6.4 to 172.9) in surviving pts, 1- and 2-year PFS were 23% and 15%, respectively (Fig 1). One and 2-year OS were 50% and 32%, respectively (Fig 2). HR cytogenetics at allo-HSCT were associated with a significantly shorter 2-year PFS (6% for HR vs. 23% for SR; p=0.007) and OS (p=0.01). A response <PR after allo-HSCT was also associated with significantly shorter 2-year PFS (p<0.001) and OS (p<0.001). Conclusions: Allo-HSCT is associated with durable remission and survival in approximately 15% of heavily pretreated pts with relapsed/refractory MM. Novel, more effective approaches are needed for patients with HR cytogenetic abnormalities. Figure 1 Progression-Free Survival Figure 1. Progression-Free Survival Figure 2 Overall Survival Figure 2.

Abstract Abstract 1343 Background: Multiple myeloma (MM) is the second most common hematological malignancy in the United States with an estimated 20,580 new cases in 2009. Over the past decade, the introduction of novel agents (thalidomide, lenalidomide and bortezomib) have played a pivotal role in improving response rates, duration of response, overall survival (OS) and quality of life. In this study we describe a single center experience with novel agents used for induction followed by high dose chemotherapy (HDT) and first autologous stem cell transplant (ASCT) in patients with MM. Method: A retrospective review of the medical records of 179 newly diagnosed patients with MM seen between October 2006 and December 2009 at The Ohio State University was performed. All patients received novel therapy containing thalidomide, bortezomib or lenalidomide as part of an induction regimen followed by ASCT. All patients received melphalan 140mg/m2 or 200mg/m2 as preparative regimen. Kaplan-Meier estimates were used to plot progression free survival and overall survival. Results: Of the 181 patients seen, 2 were excluded because they did not receive a novel agent as part of induction treatment. Of the 179 patients analyzed, median age was 56.8 years (29-80) with 30% of patients older than 60 years. African American represented 19%. Fifty-nine percent were male, 80% had Durie-Salmon (DS) stage III while 25%, 28%, 18% represented International prognostic score (IPS) stage I, II, and III respectively with 27% unknown. Median comorbidity index score was 2 (2-7) and median Karnofsky performance score (KPS) was 90% (70-100). Thirty percent had high risk genetic profile, and 73% received one line of treatment before ASCT. The median time from diagnosis to ASCT was 8.33 months (4-58). The overall response rate (ORR) prior to transplant was 84% (9% complete (CR), 29% very good partial (VGPR), and 46% partial (PR)). The ORR post ASCT was 89% (CR 45%, VGPR 22%, PR 21%). Non relapse mortality was 1% and 3% at 100 days and 1 year respectively. At a median follow up of 31 months (7-90), 69 patients (38%) had relapsed. Median progression free survival (PFS) was 29 months with 1 and 3 years PFS of 79.3% and 61.5% respectively (Fig. 1). The OS was not reached. One and 3 years OS were 93% and 88% respectively (Fig. 1). Univariate analysis showed that time to transplant > 12 months was associated with poor outcome and decreased overall survival (HR 3.30, p = 0.008). High risk genetic profile was also found to be associated with decreased overall survival although this was not statistically significant (HR 2.31, p = 0.070). Multivariate analysis found that only time to transplant > 12 months was an independent predictor of decreased OS. Significant predictors for disease progression were high risk genetic profile and time to transplant > 12 months in patients receiving 2 or more treatments before ASCT. Conclusion: Induction with novel agents followed by HDT and ASCT improves CR rate, in our case from 9% to 45%. Median PFS (29 months) was comparable to other published data. OS was not been reached after a median follow up of 31 months. Predictors of progression include high risk genetic profile and time to transplant > 12 months. The only significant predictor for survival was time to transplant. Our study suggests that an early transplant may improve OS and PFS. An extended analysis will be presented at the meeting.

Abstract Abstract 828 Introduction: Patients with multiple myeloma (MM) relapsing or progressing after allogeneic stem cell transplantation (alloSCT) have limited therapeutic options. Donor lymphocyte infusions (DLI) are used to exploit the graft-versus-myeloma effect, and pilot studies have shown that cytoreduction before DLIs could increase their efficacy. These patients are often chemo-refractory or frail, so the new drugs are an attractive option in this setting. Based on experimental and pilot studies showing the high efficacy of bortezomib in alloSCT relapse of MM, we designed a prospective multicenter study to treat these patients with 3 cycles of bortezomib-dexamethasone (VD) followed by escalating doses of DLIs (VD-DLI). The primary objective was the efficacy in terms of response as defined by IMWG criteria. Secondary objectives were to assess the incidence of GVHD, the incidence of graft failure, the progression free survival (PFS), the overall survival (OS), and the safety. Methods: Patients with relapsing or progressive MM after alloSCT were enrolled. Treatment consisted of three 21-day cycles with bortezomib 1.3mg/sqm/day iv at days 1, 4, 8, 11, and oral dexamethasone 20mg/day at days 1–2, 4–5, 8–9, 11–12, followed by 4 DLIs at escalating cell doses administered every 6 weeks. The DLIs started from 5×10^6 CD3+/kg cell dose for HLA-identical sibling donors, or 5×10^5 CD3+/kg for mismatched siblings, matched unrelated (MUD), or haploidentical donors. For every patient, the cell dose was escalated by 0.5 Log at each DLI until a maximum of 1×10^8 CD3+/kg and 1×10^7 CD3+/kg dose at the fourth DLI for HLA identical and alternative donors, respectively. DLIs were stopped anytime in case of acute GVHD, or if patients achieved >=CR after at least 2 DLIs. A safety interim analysis was run after the enrollment of the first 10 patients. Here we presented the final analysis of the study. Results: Nineteen patients were enrolled at 4 Italian transplant centers between 2007 and 2010. Sixteen patients had ISS stage I MM, two had ISS stage II, and one had ISS stage III MM. FISH data were not available. Median patients' age was 58 years (range, 34–68 years), 8 patients were female. Patients had been treated with a median of 2 lines of therapy (range, 2–5 lines): all the patients had received at least one autologous transplant, 10 had received thalidomide, 4 patients had received bortezomib and none of them was bortezomib-refractory. Two patients had grade (G) 1 peripheral neuropathy (PN) owing to previous treatments. Fifteen alloSCT donors were HLA identical siblings, 3 were MUD and one was haploidentical. One patient received one VD, one 2 VD, and 17 patients all the 3 planned VD. Two patients received one DLI, 1 patient 2 DLIs, 6 patients 3 DLIs, and 8 patients 4 DLIs. The median follow-up of the 15 (79%) surviving patients is 22 months (range, 12.5–55 months). Overall response rate (ORR) to VD was 63%: 3 patients achieved PR, 7 patients VGPR, 1 patient CR and 1 sCR; patients with SD were 5. The 17 patients receiving VD and DLIs had a 71% ORR, with 1 patient achieving PR, 7 patients achieving VGPR, 2 patients CR and 2 sCR; disease was stable in 4 patients. Twelve patients (63%) eventually progressed at a median time of 8.7 months (range, 1–22 months). Progression-free survival was 47% at one year and 33% at both 2 and 3 years of follow-up (median PFS, 12 months). Overall survival was 90% at 1 year and 79% at both 2 and 3 years of follow-up (median not reached). The incidence of aGVHD was 18% (3 patients: 2 had grade 1 and one grade 2). Five patients (29%) had limited cGVHD, none had extensive cGVHD. None of the patients experienced graft failure. During VD, 2 patients experienced G2 hematologic toxicity (thrombocytopenia). PN occurred in 5 patients (26%): 4 patients had G2 PN, and one patient had G3 PN. Other extra-hematologic toxicities more than G2 occurred only in one patient (G3 infection event). During DLI there were no >G2 hematologic or extra-hematologic toxicities. There were no treatment-related mortalities. Conclusion: This prospective study shows that VD-DLIs is feasible, well tolerated, and it can offer a high remission rate to patients with MM relapsed or refractory after alloSCT. Interestingly, the PFS and OS curves show a plateau, suggesting the achievement of a response more prolonged respect to the series previously published, relative to the non allotransplant setting.

Abstract Background Autologous stem cell transplantation (ASCT) has been a part of the standard therapy for newly diagnosed multiple myeloma and several studies showed double ASCT improved the outcome in comparison with single ASCT, especially the patients who failed to achieve very good partial remission (VGPR). Recently, the introduction of novel agents significantly improved the response rate of the treatment for the multiple myeloma. Although ASCT is still crucial for newly diagnosed myeloma patients, the role of the double ASCT is unclear in the era of novel agents. We performed a single institution-based retrospective study. Methods We reviewed the medical records of patients who treated with ASCT for multiple myeloma between January 2001 and April 2013 in National Center for Global Health and Medicine, Tokyo, Japan. The regimen of the remission induction therapy, number of stem cell transplantations, survival after the first ASCT, progression free survival, the response after the induction therapy and the first ASCT were analyzed. Results Since 2001, we performed ASCT for 167 patients. Ninety-three patients were treated with double ASCT, and 2 patients were treated with tandem ASCT–allogeneic SCT. In 127 patients were treated with vincristine, adriamycin, and dexamethasone (VAD) as an induction therapy, and 40 patients were treated with bortezomib and dexamethasone (BD). Very-good-partial-remission (VGPR) or complete remission (CR) was obtained in 25.2%, 34.6% of the patients treated with VAD, and in 45.7%, 54.3% with BD regimen before and after the transplantation respectively. Overall survival (OS) and progression free survival (PFS) did not differ significantly between VAD and BD induction, the estimated 2 year-OS was 89.8% vs. 79.5%, and the 2 year-PFS was 43.2% vs. 63.5% respectively. Double transplantation improved PFS and OS in VAD induction than single transplantation (p=0.000, p=0.002). In BD induction, patients who failed to achieve VGPR or better after the first ASCT, double transplantation improved OS (p=0.010) but not PFS. In both VAD induction and BD, there was no significant survival benefit in double transplantation in patients who achieved VGPR or better. Conclusion The achievement of VGPR or better after the ASCT resulted in significantly better PFS. The role of double transplantation is still crucial for patients with inadequate response after the first ASCT even in the era of novel agents.

Purpose We assessed response to treatment, toxicity, time to progression, progression-free survival, and overall survival in patients newly diagnosed with multiple myeloma who were ineligible for or unwilling to undergo transplantation and who were treated with a combination of lenalidomide and low-dose dexamethasone for a fixed 6 cycles in a resource-constrained environment.Methods This pragmatic study, conducted in a single tertiary cancer centre in South India, enrolled patients from May 2009 till April 2011. Treatment included lenalidomide 25 mg daily for 21 days, with dexamethasone 40 mg on days 1, 8, 15, and 22 of a 28-day cycle, for 6 cycles. Response was evaluated after the 3rd and 6th cycles of treatment. All patients were followed for 5 years.Results The study enrolled 51 patients. Median age in the group was 61 years (range: 38–76 years). Immunoglobulin G or A myeloma constituted 70.6% of the diagnoses, and light-chain myeloma constituted 29.4%. Stages i, ii, and iii (International Staging System) disease constituted 21.4%, 28.6%, and 50% of the diagnoses respectively. All patients were transplantation-eligible, but 34 (66.7%) refused for economic reasons. After treatment, 19.6% of the patients achieved a stringent complete response; 35.3%, a complete response; 5.9%, a very good partial response; and 29.4%, a partial response, for an overall response rate of 90.2%. Stable disease was seen in 3.9% of patients, and progressive disease, in 5.9%. Grade 3 or greater nonhematologic and hematologic toxicity occurred in 35.2% and 11.7% of patients respectively. Pulmonary embolism occurred in 1 patient. No patient experienced deep-vein thrombosis or peripheral neuropathy. The median follow-up duration was 66 months. All patients experienced disease progression. Median progression-free survival was 16 months. In 10 patients, re-challenge with lenalidomide and dexamethasone achieved a second complete response. At the time of writing, 19 patients had died. The overall survival rate at 5 years was 62.74%. Median overall survival is not yet reached.Conclusions In a resource-constrained setting, lenalidomide with low-dose dexamethasone is an effective treatment with acceptable toxicity in patients newly diagnosed with multiple myeloma and not planned for transplantation. Complete responses were significantly more frequent than reported in the Western literature. Occurrence of clinical deep-vein thrombosis was rare, but hyperglycemia was common. An abbreviated course of treatment is suboptimal in multiple myeloma. Maintenance regimens should be advocated.
