The Impact

Abstract Abstract 4111 In multiple myeloma (MM), the impact of complete response (CR) and very good partial response (VGPR) achievement has been shown mostly after introduction of high dose therapy (HDT) supported by autologous stem cell transplant (ASCT). Recently, the IFM group reported the impact of achievement of CR and VGPR in double ASCT. The purpose of this study is to confirm the prognostic value of CR/VGPR in a large group of patients treated with single ASCT. Methods All consecutive patients who underwent single ASCT at Princess Margaret Hospital between January 2000 and December 2007 were evaluated. Patients were mobilized with cyclophosphamide and G-CSF and majority were conditioned with melphalan 200mg/m2. Response to therapy was assessed according to the IMWC including VGPR. Progression Free Survival (PFS) and Overall Survival (OS) were measured from transplant date to the date of death or last follow-up. OS and DFS were analyzed using the Kaplan-Meier Method. The Cox proportional hazard model was used to assess CR and VGPR and some other prognostic markers at presentation such as age, B2Mg> 460 μmol/L, LDH> 350 IU/L, CRP> 20mg/L, albumin<35g/L and creatinine > 200 μmol/L. All p-values were 2-sided and statistically significant if <0.05. Results 788 patients were identified for the study; their median age was 56 years (30–73). Patient's characteristics are listed in Table 1. Response was assessed at day 100 after ASCT and showed a CR of 6%, PR of 37.5%, and VGPR of 53% (Overall Response rate of 95.5%). Median OS and PFS for the group were 77.43 months and 20.63 months respectively. The median OS and PFS were significantly better for patients who achieved CR/VGPR, 104.5 months versus 51.7 months, and 26.3 months versus 13.53 months respectively. With a median follow-up of 44 months there is no significant difference in OS for those patients who achieved VGPR/CR after induction therapy with novel agents. However, PFS is better in those patients receiving novel agents who achieved VGPR/CR (Median PFS of 24.63months versus 12.4 months respectively (p=0.01). Multivariate analysis shows CR/VGPR as an independent prognostic factor for OS and PFS (Fig 1 and 2). B2Mg> 460 μmol/L, LDH> 350 IU/L, CRP > 20mg/L, albumin<35g/L and creatinine > 200 μmol/L failed to be important factor for survival in the multivariate analysis. Our data suggests that VGPR/CR is clearly important in the pre-novel agents era and for the smaller group of patients who had novel agents induction there is a benefit in PFS and with a longer follow-up perhaps in OS. In conclusion, VGPR/CR remains a simple and powerful indicator in the context of single ASCT and should be considered a relevant objective for MM treatment. Table 1.

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.

e20509 Background: We evaluated outcomes of patients with multiple myeloma (MM) ≥ 70 years who were seen for Autologous Stem Cell Transplant (ASCT) consult, based on whether they underwent transplant vs. non-transplant treatment. Methods: 138 patients with MM ≥ 70 years (median 71, range 70-78) were evaluated in the BMT clinic from 1/2010 to 11/2019 for a transplant consult. Results: Of the 138 patients, 53 proceeded to ASCT. ASCT was not pursued in 85 patients despite most (79%) being eligible for transplant. Reasons for deferring ASCT in eligible patients included patient preference (48%, n = 32) and physician preference (52%, n = 35). 68 patients were seen during first-line therapy, of which 29 underwent upfront transplant. The remainder were seen at second-line or beyond. There was no difference in baseline characteristics among the 113 patients with available follow-up (ASCT = 53, non-ASCT = 60), including median age (71 vs. 72 years, p = 0.4), high-risk cytogenetics (41% vs. 31%, p = 0.4), high-risk HCT-CI (32% vs. 20% p = 0.2), and ISS stage III (34% vs. 27%, p = 0.6). In the 53 patients who underwent transplant, conditioning melphalan dose was 200 mg/m2 (75%, n = 40) and 140 mg/m2 (25%, n = 13). Day 100 transplant related mortality was 0% (n = 0). Progression-free survival (PFS) and overall survival (OS) were compared in patients who were seen for consultation within 1 year of diagnosis (n = 80). With a median follow-up of 27 months, median PFS amongst patients ≥ 70 years undergoing ASCT (n = 39) was 47 months compared to 34 months in the non-ASCT (n = 41) group, p = 0.006. Median OS was not reached in either group. Estimated 5-years OS was 76% in the ASCT group and 82% in the non-ASCT group (p = 0.6). There was no difference in PFS of patients ≥ 70 undergoing ASCT compared to a cotemporaneous cohort of patients < 70 (n = 639) from our institution (47 vs. 57 months, p = 0.3). Conclusions: Selected patients ≥ 70 years with MM undergoing ASCT have better PFS compared to patients with similar characteristics who do not undergo ASCT. ASCT is safe in this older population and outcomes were similar compared to younger patients. [Table: see text]

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 High dose Melphalan (Mel) has demonstrated efficacy in the treatment of multiple myeloma (MM). Mitoxantrone (Mit), in combination with vincristine and prednisone, also has demonstrated activity in MM with the benefit of less cardiac toxicity than other standard regimens. In this trial Mel and Mit were combined as a transplant preparative regimen. Mit was given as a prolonged 6 hour infusion on 2 separate days to increase intracellular drug levels and decrease cardiac toxicity (Kaminer et al. Cancer1990; 65, 2619–2623; Koc et al. Hematol Oncol2004;22:43–53). PATIENTS: 35 patients with a diagnosis of MM were enrolled between 9/98–6/02. Median age was 59 (range, 38–69); 60% had received ≥ 2 previous regimens (range, 1–6). The median time from diagnosis to transplant was 9 months (95% CI, 8–12 months). 57% had stage III disease and 26% stage II at diagnosis; median Beta-2 microglobulin was 3.6 mg/L (available in only 13 patients). All patients completed therapy with Mit 30mg/m2/day infused over 6 hours on days -6 and -5 and Mel 180mg/m2 on day -1. RESULTS: The median follow-up for survivors was approximately 45 months (range, 3–84 months). The median times to granulocyte and platelet engraftment were 11 days and 14 days respectively. 2 patients failed to engraft; 1 proceeded to allogeneic transplant, the other died on day 28 secondary to sepsis. The 100-day TRM was 2.9%. The median progression free survival (PFS) was 20 months (95% CI, 13–31) (Figure 1) with a median overall survival (OS) of 57 months (Figure 2). 4 patients are alive and progression free more than 48 months out from transplant. 8/35 (23%) of patients achieved a complete response (CR). Of the 8 patients who had a CR, 7 (20% of total patients) are still alive and progression free with a median follow-up of 39 months after transplant (range, 12 to 80 months). The achievement of a CR was significantly associated with longer PFS but not with OS. The mean CD34 count of infused cells was 4.92 ×106/kg and did not appear to be significantly associated with CR rate, OS, or time to engraftment of platelets or granulocytes. Overall, therapy was well tolerated with a median of 8 days (range, 0–15) of any grade of mucositis and a median of 3 days of fever. The mean LVEF on MUGA was 64% pre-transplant and decreased to 58% post-transplant. 1 patient with diabetes and hypertension developed congestive heart failure after discharge from the hospital but with therapy the LVEF returned to normal. CONCLUSION: The combination of Mel and infusional Mit is an effective regimen with 23% CR rate despite multiple previous therapies. The median OS of 57 months compares well to other transplant trials and patients who achieved a CR demonstrated better long-term PFS. Figure Figure Figure Figure

Abstract Background: Therapeutic options for patients with Multiple myeloma (MM) whose disease has relapsed after a prior autologous stem cell transplant (SCT) include an expanding armamentarium of novel agents, often combined with traditional chemotherapy, or a second SCT, with no clear standard of care. Upfront tandem transplantation has been shown to improve both progression free survival and overall survival. But currently, there is little data regarding the application of tandem SCT in relapsed multiple myeloma patients. Methods: We retrospectively analyzed the outcomes of patients who underwent salvage melphalan-based tandem SCT for relapsed MM at University of Iowa Hospitals and clinics. Progression free survival (PFS) was defined as the time from date of the first salvage SCT to disease progression or death, whereas overall survival (OS) was defined from the date of the first salvage SCT to the date of death from any cause. Results: Between 2012 and 2015, 12 patients with MM received tandem autograft (total 24 transplants) for relapsed disease at our center. Conditioning was with VDT-melphalan 200mg/m2 (21/24), VDT-MEL 140mg/m2 (2/24) and Velcade, gemcitabine, BCNU, melphalan and dexamethasone (1/24). The median age at the salvage SCT was 48 years (range 37-58); 7 patients were female. 17% had high risk cytogenetics (including t(4;14), +1q, p53 loss) at the time of salvage SCT. Median time between previous transplant and progression of disease was 34 months (range 8-108). Of the 7 patients, who received re-induction therapy, 71% had chemotherapy refractory disease prior to salvage SCT. Response was assessed at 2-3 months post-SCT. Overall response rate was 92%. 7/12 (58%) patients achieved stringent complete remission, one patient achieved CR, one patient achieved near CR, 2/12 patients achieved VGPR and 1/12 had stable disease (SD). Following salvage tandem SCT, all patients received consolidation therapy with three drug combination, intended to be given for two years. Three patients have shown progressive disease at the time of analysis. The median PFS was 390 days (range 265- 1085) (Table-1); the median OS was 517 days (range 338-1085) (Table-2). Rate of progression free survival in the 10 evaluable patients at one year was 80%. There was no transplant related mortality. One patient died of progressive disease. Conclusions: Salvage tandem SCT is an effective strategy for relapsed MM and is especially effective in patients who had received less intensive therapy initially (single transplant and no maintenance therapy). Incorporation of novel agents (monoclonal antibodies and high doses of carfilzomib) into maintenance strategies may further improve outcomes. Figure 1.

Depth Of Response

8004 Background: D-VTd plus ASCT was approved for transplant-eligible (TE) NDMM based on part 1 of CASSIOPEIA. We report a prespecified interim analysis of CASSIOPEIA part 2: DARA maintenance vs OBS in pts with ≥partial response (PR) in part 1, regardless of induction/consolidation (ind/cons) treatment. Methods: CASSIOPEIA is a 2-part, randomized, open-label, phase 3 study in TE NDMM. Pts received 4 cycles ind and 2 cycles cons with D-VTd or VTd. 886 pts who achieved ≥PR were rerandomized to DARA 16 mg/kg IV Q8W for up to 2 yr (n = 442) or OBS (n = 444) until progressive disease per IMWG. Pts were stratified by ind (D-VTd vs VTd) and depth of response (minimum residual disease [MRD] status and post cons response ≥PR). Primary endpoint was progression-free survival (PFS) after second randomization. This interim analysis assessed efficacy and safety after 281 PFS events. A preplanned hierarchical procedure tested key secondary endpoints: time to progression (TTP), ≥complete response (CR), MRD negativity rates by NGS and overall survival (OS). Results: At median follow-up of 35.4 mo, median PFS was not reached (NR) with DARA and 46.7 mo with OBS (HR 0.53; 95% CI 0.42–0.68; P <0.0001). PFS advantage for DARA was consistent across most subgroups. However, a prespecified analysis showed significant interaction with ind/cons treatment arm ( P< 0.0001). PFS HR for DARA vs OBS was 0.32 (95% CI 0.23–0.46) in the VTd arm and 1.02 (0.71–1.47) in the D-VTd arm. Median TTP was NR for DARA vs 46.7 mo for OBS (HR 0.49; 95% CI 0.38–0.62; P <0.0001). More pts in the DARA vs OBS arm achieved ≥CR (72.9% vs 60.8%; OR 2.17; 95% CI 1.54–3.07; P <0.0001). MRD negativity (in ≥CR pts at 10-5) was 58.6% with DARA vs 47.1% with OBS (OR 1.80; 95% CI 1.33–2.43; P= 0.0001). Median OS was NR in either arm. Most common (≥2.5%) grade 3/4 adverse events (AEs) with DARA vs OBS were pneumonia (2.5% vs 1.4%), lymphopenia (3.6% vs 1.8%), and hypertension (3.0% vs 1.6%). Serious AEs occurred in 22.7% (DARA) vs 18.9% (OBS) of pts; the most common (≥2.5%) was pneumonia (2.5% vs 1.6%). 13 (3.0%) pts discontinued DARA due to an AE. The rate of infusion-related reactions was 54.5% (DARA-naïve pts) and 2.2% (prior DARA pts); 90% were grade 1/2.Second primary malignancies occurred in 5.5% (DARA) vs 2.7% (OBS) of pts. Conclusions: CASSIOPEIA part 2 demonstrated a clinical benefit of DARA maintenance in TE NDMM pts, with significantly longer PFS for DARA vs OBS. With current follow-up, maintenance PFS benefit appeared only in pts treated with VTd as ind/cons. Pts who received D-VTd ind/cons with or without DARA maintenance achieved similar PFS; longer follow-up is needed for PFS2 and OS. DARA significantly increased deeper response and MRD negativity rates vs OBS, and was well tolerated with no new safety signals. Clinical trial information: NCT02541383.

Abstract p53 deletion by fluorescence in situ hybridization (FISH) has been reported in about 10% of newly diagnosed patients (pts) with multiple myeloma (MM) and has been associated with a poor prognosis. Previous data from our centre has demonstrated that the progression-free survival (PFS) and overall survival (OS) of these pts after a single autologous stem cell transplant (ASCT) is only 16.9 and 48.2 months, respectively, compared to 24.4 and 76.6 mos, respectively, in all pts transplanted during the same time period (Mikhael et al, Blood2007; 110: abstract 953). Minimal information is available on the treatment (Tx) and course of these pts following disease progression. Therefore, we performed a retrospective review of all MM pts treated at our institution who were found to have p53 deletion. We identified 31 pts with relapsed/refractory (rel/ref) MM with this cytogenetic abnormality. At diagnosis, median age was 54 years (range, 31–70), hemoglobin 97 g/L (range, 67–149), creatinine 96 μmol/L (range, 28–1751), beta 2-microglobulin 314 nmol/L (range, 225–437), CRP 3 mg/L (range, 2–7) and LDH 205 U/L (range, 82–478); 58% were male. Immunoglobulin subtypes included: IgG (14 pts), IgA (8 pts), IgD (2 pts) and light chain only (7 pts). Concomitant cytogenetic abnormalities included 13q deletion in 68% and t(4;14) in 67% of pts evaluable. Thirty-nine percent developed plasma cell leukemia (PCL) at some point in the disease course, which was associated with a poor OS (p=0.005). All but 5 had undergone prior ASCT with a median time from diagnosis to ASCT of 8 (95% CI, 4–145) mos. Txs given for rel/ref MM consisted of the following regimens: thalidomide-based in 15, bortezomib-based in 12, lenalidomide-based in 11, alkylating agents in 9 and steroids only in 5 pts, and other regimens (D-PACE or investigational drugs) in 7 pts. The median follow-up from diagnosis in these pts is 45 (95% CI, 4–145) mos. The overall response rate (≥PR) (ORR), median PFS and median OS from the start of each regimen is shown below. Agent Median duration of Tx (mos) ORR(%) Median PFS (mos) Median OS (mos) Thalidomide 6.2 20% 5.0 11.9 Bortezomib 5.2 50% 5.6 36.1 Lenalidomide 10.6 60% 4.8 36.1 Alkylating agents 6.0 11% 5.1 30.0 Steroids 1.9 20% 1.9 33.4 Other 2.2 43% 6.3 33.4 We conclude: 1) Median PFS in pts with the p53 deletion is less than 6 months, with an OS of 2.5–3 yrs; 2) novel agents other than thalidomide produce the highest ORR in rel/ref MM with p53 deletion; 3) the short OS in the thalidomide group is likely related to the unavailability of other novel agents for subsequent relapses, as the majority of the pts were treated before 2004; 4) better strategies/drugs are required for these pts.

Abstract Several factors influencing disease progression and survival have been identified in multiple myeloma (MM). We analysed a series of 49 consecutive patients with MM that underwent autologous haematopoietic progenitor cell transplant (HPCT) in one center regarding the following variables: use of G-CSF for haematopoietic recovery post-transplant; recovery of normal IgM levels at day +100 post-transplant; levels of lymphocytes namely of the CD4+ and CD8+ subsets also at day +100. Before 2006, all patients had G-CSF starting 24 hours after the cell infusion until neutrophil &gt; 500×10^9/L in two consecutive days; in the years 2006–2008, no G-CSF was given to transplanted patients. A historical comparison was done and at the time of this study no significant difference in progression free survival (Kaplan-Meyer analysis), was detected between the two groups, possibly due to the shorter follow-up of the “no G-CSF” (n=19) group; nevertheless median progression free survival (PFS) in the “G-CSF” group was 12 months while median PFS was not attained in the “no G-CSF” group (median follow-up = 7 months). Post transplant IgM levels were also determined in 39 patients. Eighteen patients recovered normal IgM levels at day +100 (46.8 %) and 21 (53.8 %) did not. Comparison of Kaplan-Meyer curves for the two groups did not show any statistically significant difference but there is a sharp difference between median PFS of the “low IgM” (10 months) and the “normal IgM” (27 months) groups. CD4/CD8 ratio was determined in 18 patients at day +100. The ratio varied between 0 and 0.63 (median – 0.305). No correlation was found between post-transplant IgM recovery and CD4/CD8 ratio. In conclusion, in our series of MM patients treated with autologous HPCT we could not find a definite relationship between immunologic recovery and response to treatment although there is a trend to a better outlook of the patients which recover normal IgM levels. It is also uncertain whether use of G-CSF in the post-transplant period would have any effect on disease behaviour.

Abstract Introduction Introduction of novel agents (Immunomodulators-thalidomide/lenalidomide and proteasome inhibitors-bortezomib) has really changed the treatment outcomes in myeloma patients. This is applicable to patients both eligible and ineligible for autologous stem cell transplant. In developing countries, like India, access to the generic forms makes it easy for patients to have treatment with all types of novel agents. In this study, we did a retrospective audit of the treatment outcomes with the generic forms of novel agents in a group of transplant ineligible patients. Methodology All newly diagnosed myeloma cases from January 2011 to December 2014, who did not undergo stem cell transplant, were included for the study. Criteria for diagnosis and treatment response were according to the latest IMWG guidelines. Baseline demographic data and details regarding CRAB criteria, Performance Status (PS), comorbidities, type and duration of treatment, and toxicity were recorded. Toxicity was graded according to CTCAE v 4. Only the maximum grade of a particular toxicity per patient has been reported. Dates of death if applicable was noted, and if patients were alive, date of last follow up was documented. Survival was analysed by non-parametric methods (Kaplan Meier and Cox proportional hazard model) and the variables considered were 'treatment completed' versus 'not completed', 'response' (PR or more) versus 'no response', 'maintenance received' versus 'not received', 'age ≤65 years' versus 'age >65 years', and international staging system (ISS) ' stage 1' versus 'stage 2 or 3'. Analysis was performed with R v 3.2.0 (http://cran.r-project.org.) Results One hundred and nineteen patients (53 males, 66 females) with median age of 62 years (range 44-85) were included as per eligibility criteria. Eighty four (70%) patients had IgG, and 21 (17.6%) had IgA, and 14 (11.7%) had light chain myeloma. Twenty two (18.4%) patients were in ISS stage 1, 36 (30%) were in stage 2 and 39 (32.7%) were in stage 3, with data missing in 22 patients. Fifty seven (47.9%) patients were having comorbidity. Ninety seven patients (81%) were having PS ≤ 2 and 21(17.6%) had PS >2. Lenalidomide based regimen was given in 29 patients, thalidomide based in 65 and bortezomib based in 25 patients. Overall response (PR or more) was documented in 74 (72%), out of 102 evaluable patients. VGPR or more was documented in 56 (55%), and PR in 18(17.6%) patients. Seventy three (61%) patients had some form of toxicity. Grade 3 nonhematologic toxicity occurred in 7 patients (peripheral neuropathy in 2, diarrhea in 2 and DVT in 3), grade 4 in none. Grade 3-4 hematologic toxicity occurred in 8 patients (grade 3 anemia and thrombocytopenia in 3 each, and grade 4 thrombocytopenia in 2 patients). Median follow up duration was 22 months. Estimated 3 year OS for entire group was 60% (95 % CI 47-77%) (Figure 1). Median PFS was 22 months (95 % CI 19- 25) (Figure 2). Variables significantly predicting OS were, treatment completed or not (47 Vs 32 months, HR= 0.372, P= 0.011) and age ≤ 65 versus age >65(47 Vs 31 months, HR= 4.15, P<0.001). Similarly for PFS the significant variables were response or not (24 Vs 7 months, HR= 4.89, P<0.001) and ISS stage 1 Vs stage 2 or 3 (25 Vs 19 months, HR=2.39, P=0.021). Conclusion Treatment with the generic forms of novel agents leads to comparable response rates and survival in patients with myeloma. So, use of these agents with lower cost seems justifiable in the real world practice where it may be difficult to access the innovators for the exuberant cost. Figure 1.

Purpose Bortezomib-melphalan-prednisone (VMP) has improved overall survival in multiple myeloma. This randomized trial compared VMP plus thalidomide (VMPT) induction followed by bortezomib-thalidomide maintenance (VMPT-VT) with VMP in patients with newly diagnosed multiple myeloma. Patients and Methods We randomly assigned 511 patients who were not eligible for transplantation to receive VMPT-VT (nine 5-week cycles of VMPT followed by 2 years of VT maintenance) or VMP (nine 5-week cycles without maintenance). Results In the initial analysis with a median follow-up of 23 months, VMPT-VT improved complete response rate from 24% to 38% and 3-year progression-free-survival (PFS) from 41% to 56% compared with VMP. In this analysis, median follow-up was 54 months. The median PFS was significantly longer with VMPT-VT (35.3 months) than with VMP (24.8 months; hazard ratio [HR], 0.58; P < .001). The time to next therapy was 46.6 months in the VMPT-VT group and 27.8 months in the VMP group (HR, 0.52; P < .001). The 5-year overall survival (OS) was greater with VMPT-VT (61%) than with VMP (51%; HR, 0.70; P = .01). Survival from relapse was identical in both groups (HR, 0.92; P = .63). In the VMPT-VT group, the most frequent grade 3 to 4 adverse events included neutropenia (38%), thrombocytopenia (22%), peripheral neuropathy (11%), and cardiologic events (11%). All of these, except for thrombocytopenia, were significantly more frequent in the VMPT-VT patients. Conclusion Bortezomib and thalidomide significantly improved OS in multiple myeloma patients not eligible for transplantation.
