Abstract Background: Multiple myeloma (MM) risk stratification schemata such as the International Staging System (ISS) and Revised-ISS (R-ISS) were derived from clinical trial subjects made up predominately of younger White individuals with adequate renal function. It is unknown whether these prognostic indices are applicable to all patients with newly diagnosed (ND) MM, especially among Black individuals, older adults, and those with renal dysfunction. The R-ISS expanded on the ISS by including and serum lactate dehydrogenase (LDH) and high-risk cytogenetic abnormalities (HRCA) identified by fluorescence in-situ hybridization (FISH), but HRCA may not translate into poor prognosis for older adults and for Black individuals. We sought to create an inclusive risk prognostic index for NDMM using real-world data derived from electronic health records. Methods: De-identified NDMM patient-level data in the real-world setting was provided by COTA, Inc. 3000 patients were identified who met the inclusion criteria of NDMM between 2005 and 2020. Baseline diagnostic parameters available within 60 days before or after diagnosis were included. Progression free survival (PFS) was defined as the time from diagnosis to disease progression or death of any cause. Overall survival (OS) was defined as the time from diagnosis to death of any cause. Proportional hazards models were used to calculate hazard ratios (HR) and 95% confidence intervals for all-cause mortality. Age-adjusted univariate analyses identified variables significantly associated with OS, and continuous variables were dichotomized based on accepted cutoffs. Multivariate Cox models to identify the variables with the strongest association with OS were performed adjusting for age, sex, Black race, receipt of proteasome inhibitor and immunomodulatory imide during induction, autologous stem cell transplant within 1 year of diagnosis, ECOG performance status, and creatinine. An additive risk score was created with one point given to each significant variable. The risk score was then validated for PFS using the Multiple Myeloma Research Foundation's (MMRF) CoMMpass database (version IA15). Results: 3000 NDMM pts from the COTA, Inc. real-world database were initially evaluated, and a total of 689 NDMM pts had sufficient level of data to be included. The median follow-up time was 49.9 months (interquartile range (IQR) 29.1-76.2 months). Median age was 64 (IQR 32-86), including 44% age 65+. Of the 607 with reported race, 474 (78%) were White, 86 (14%) Black, 17 (3%) Asian, and 30 (5%) other. Of the 676 pts with reported serum creatinine (mg/dL), the median was 1 mg/dL (IQR 0.8-1.3) with 85 (13%) measuring >2 mg/dL. Examined peripheral blood variables were: calcium (corrected for albumin), albumin<3.5 mg/dL, beta2-microgloublin (B2M) >3.5 mcg/mL, LDH >250 U/L, hemoglobin <10 g/dL, M-spike >3 g/dL, and IgA isotype. Variables with significance using multivariate analysis at p<0.1 were: LDH>250 U/L, B2M >3.5 mcg/mL, hemoglobin <10 g/dL, and IgA isotype. These variables were simultaneously present in 558 patients. Patients were stratified into 3 groups: standard (std score = 0, n=186), intermediate (int score = 1-2, n=295), and high (score 3-4, n=77) risk. For this inclusive risk prognostic index (IRPI), the c-statistic was 0.61 for OS (HR 2.0, 95% CI 1.5-2.6, p<0.001) which compared favorably to the c-statistic for ISS (c=0.64, HR 1.8, 95% CI 1.5-2.2, p<0.001) and for R-ISS (c=0.63, HR 2.0, 95% CI 1.6-2.6). For the IRPI, median OS was 218 (std) vs 121.5 (int) vs 79.5 months (high). In comparison, median OS by ISS was 198.9 (stage I) vs 121.6 (stage II) vs 80.6 months (stage III), and by R-ISS: 198.9 (I) vs 121.6 (II) vs 79.5 months (III). Validation of the inclusive risk prognostic index (IRPI) using the MMRF CoMMpass database in 938 patients with all four criteria showed median PFS was 44 (std) vs 33 (int) vs 20.5 months (high). In comparison, median PFS by ISS was 45.9 (I) vs 31.5 (II) vs 20.5 (III) months. Median PFS by R-ISS was 50.1 (I) vs 32.7 (II) vs 19.1 (III) months. Conclusions: Employing real-world datasets that incorporate a more diverse patient population led to the generation of an inclusive risk prognostic index incorporating beta2-microgloublin, LDH, hemoglobin, and IgA isotype. This IRPI does not require bone marrow sampling, performs similarly to ISS and R-ISS in predicting PFS, and with datasets with longer follow-up may prove to predict OS. Figure 1 Figure 1.

Triplet Regimen

Abstract Introduction: Triplet therapies are used for treatment (Tx) of both transplant-eligible and -ineligible patients (pts) with newly diagnosed multiple myeloma (NDMM). Actual patterns and outcomes of Tx are not fully understood. Connect MM® is the first and largest multicenter, US-based, prospective observational cohort study designed to characterize Tx patterns and outcomes for pts with NDMM. This analysis describes demographic and disease characteristics of pts who received triplet Tx as an induction regimen and for whom transplant was or was not intended. The analysis explores the relationship of these factors with overall survival (OS) and other efficacy endpoints. Patients and Methods: Pts aged ≥ 18 y with NDMM within 60 days of diagnosis were eligible for enrollment regardless of disease severity, medical history, or comorbidities. Data including transplant intent (yes/no) was collected at baseline; follow-up data was collected quarterly thereafter. Based on the initial intent, 2 groups were identified: patients with intent to transplant who received transplant (TT) and pts with no intent to transplant who did not receive a transplant (NT). Triplet Tx was defined as the combination of ≥ 3 concurrent therapeutic agents in the first course of Tx (within 56 days of study entry). KM analysis adjusted for age was conducted for OS. Because decisions on use of transplant and triplet therapy are influenced by multiple factors, a multivariable Cox regression analysis was performed to evaluate the contribution of the triplet therapy (yes/no) to OS and was adjusted for other variables, including age, comorbidities, and ISS staging. Results: Between September 2009 and December 2011, 1493 pts were enrolled. This analysis was on 1436 pts: 650 pts with transplant intent and 786 pts without transplant intent. The data cutoff date was November 30, 2014, and the median follow-up for overall survival (OS) was 33.8 mos. Of pts with transplant intent, 451 (69%) received transplant (TT) and 199 (31%) did not. Of pts without transplant intent, 62 (8%) received transplant and 724 (92%) did not (NT). The abstract focuses on TT and NT groups only. NT pts tended to be older and have more advanced ISS staging and higher β2-microglobulin levels than TT pts (Table). The most common triplet regimen given during the first course treatment (within 56 days) was lenalidomide, bortezomib, and dexamethasone (RVd). RVd was administered to 34% of the NT pts (76/225) and 59% of the TT pts (152/257). The most common non-triplet regimen was bortezomib and dexamethasone (Vd), which was given to 31% of NT pts (156/499) and 38% of TT pts (73/194). Within the NT group, pts given triplet Tx had a lower risk of death than those who did not receive triplet Tx (P = .0013). The multivariable analysis found triplet Tx to be associated with a 36% reduced risk of death (hazard ratio [HR] = 0.64 [95% CI, 0.50-0.82]; P = .001). ISS disease stage (HR = 1.43 [95% CI, 1.21-1.69]; P < .001) and history of diabetes (HR = 1.38 [95% CI, 1.08-1.78]; P = .012) were negative prognostic factors for OS. Within the TT group, pts who received triplet Tx did not attain an OS benefit (P = .8993), and no baseline characteristics were significantly associated with OS. These results may be limited by other factors not considered that may have influenced physicians' choice of treatment, including the use of maintenance therapy and a short follow-up period of 33.8 months. Conclusions: Triplet Tx as a first regimen is associated with longer OS in pts without transplant intent who did not receive a transplant. RVd and Vd were the most common first Tx regimens, respectively. Continued follow-up of these pts and enrollment of an additional cohort will provide additional data with mature follow-up. Table 1.

Abstract Abstract 862 Background: Carfilzomib (Cfz) is a novel, irreversible proteasome inhibitor that has demonstrated promising single-agent activity and favorable toxicity profile, including very low rates of peripheral neuropathy and neutropenia in relapsed/refractory multiple myeloma (MM). Combining Cfz with Lenalidomide (Revlimid®, Len), and Dexamethasone (Dex) into CRd shows an additive anti-MM effect in preclinical studies and lack of overlapping toxicity allowing for the use of these agents at full doses and for extended duration of time in relapsed/refractory MM (Niesvizky et al, ASH, 2009). This Phase I/II study was designed to determine the maximum tolerated dose (MTD) of CRd and to assess safety and evaluate efficacy of this combination in newly diagnosed MM. Methods: In Phase I, dose escalation follows the TITE-CRM algorithm, with Cfz as the only escalating agent starting at 20 mg/m2 (level 1), maximal planned dose 27 mg/m2 (level 2), and 15 mg/m2, if needed (level -1), given IV on days 1, 2, 8, 9, 15, 16 in 28-day cycles. Len is used at 25 mg PO (days 1–21), and Dex at 40/20 mg PO weekly (cycles 1–4/5-8) for all dose levels. Based on toxicity assessment, the study was amended to add dose level 3 with Cfz at 36 mg/m2 and the number of pts in the Phase I was increased to 35. A total of 36 pts are planned to be treated at the MTD in Phase I/II. Pts who achieve ≥ PR can proceed to stem cell collection (SCC) and autologous stem cell transplant (ASCT) after ≥ 4 cycles, although per protocol design, ASCT candidates are offered to continue CRd treatment after SCC. After completion of 8 cycles, pts receive 28-day maintenance cycles with Cfz (days 1, 2 15, 16), Len days 1–21, and Dex weekly at the doses tolerated at the end of 8 cycles. Responses are assessed by IMWG criteria with the addition of nCR. Results: The study has enrolled 24 pts to date, 4 pts at level 1 (Cfz 20), 14 at level 2 (Cfz 27) and at 6 at level 3 (Cfz 36). Toxicity data are available for 21 pts, of which 19 have completed at least the first cycle required for DLT assessment; 2 pts were removed during the first cycle for events unrelated to study therapy (1 at level 1 and 1 at level 2), and 3 are currently within their first cycle of treatment. There was a single DLT event at dose level 2 (non-febrile neutropenia requiring dose reduction of Len per protocol) and the MTD has not been reached. Hematologic toxicities were reversible and included Grade (G) 3/4 neutropenia in 3 pts, G3/4 thrombocytopenia in 3, and G3 anemia in 2. There have been additional G3 non-hematologic AEs including 1 case of DVT while on ASA prophylaxis, 1 fatigue, 1 mood alteration, and 5 glucose elevations; the last 2 AEs were related to Dex. There was no emergence of peripheral neuropathy (PN), even after prolonged treatment, except in 2 pts who developed G1 sensory PN. Twenty-three pts continue on treatment, most (20 pts) without need for any dose modifications. After a median of 4 (range 1–8) months of treatment, preliminary response rates by IMWG in 19 evaluable pts who completed at least 1 cycle are: 100% ≥ PR, 63% ≥ VGPR, 37% CR/nCR, including 3 pts with sCR. Responses were rapid with 17 of 19 pts achieving PR after 1 cycle and improving responses with continuing therapy in all pts. To date, 7 pts proceeded to SCC using growth factors only, with a median 6.3 × 106 CD34+ cells/kg collected (range 4.1–8.2), after a median of 4 cycles of CRd (range 4–8); all resumed CRd treatment after SCC. After a median of 4 months of follow-up, none of evaluable pts progressed and all are alive. Conclusion: CRd is well tolerated and highly active in newly diagnosed MM with ≥ PR of 100%, including 63% ≥VGPR and 37% CR/nCR. Accrual is ongoing, with updated toxicity and efficacy data to be presented at the meeting. The results of this study represent the first report of treatment of frontline myeloma with Cfz to date, and provide additional support to recently initiated Phase 3 trial of CRd vs. Rd in relapsed MM.

Abstract Introduction New drugs have significantly improved the outcome of MM patients (pts) increasing both progression free survival (PFS) and overall survival (OS). Among new drugs lenalidomide (LEN) due to its oral availability and favourable toxicity profile is an attractive option both as an induction and as a maintenance treatment, with different studies demonstrating its effectiveness. Long term therapy with LEN, however, has been associated with an increased risk of developing SPMs. Aims We are conducting a large phase III study to evaluate the use of LEN as induction and/or as maintenance therapy. The primary end points of the study are OS and PFS. Secondary end points are response and toxicity. Methods Pts are treated following an intensive or a non intensive pathway based on their eligibility for high dose Melphalan (HDM) and stem cell transplantation (ASCT) and are randomised to receive induction therapy with cyclophosphamide and dexamethasone combined with either LEN (CRD) or thalidomide (CTD). Pts failing to achieve an optimal response are randomised to receive additional therapy with cyclophosphamide, dexamethasone and bortezomib (CVD) or no extra therapy. Pts with minimal or no response will automatically receive further therapy with CVD. A randomisation between LEN maintenance and no maintenance is also performed. Data on the occurrence of SPMs are being routinely collected as part of safety assessment during all protocol phases and follow up. Analyses were performed on treatment actually received. Results As per cut off of the 23rd July, 2371 pts have undergone the induction randomisation, of which 2368 are eligible for the safety analysis; 794 pts entered maintenance randomisation. The median follow up is 1.36 years from initiation of the study and 1.06 years from maintenance randomisation. Localised skin cancer other than melanoma were considered as non-invasive SPMs. At the time of the present analysis 17 SPMs have been reported with a cumulative incidence rate of 0.7% (cumulative rate of 0.6% for invasive SPMs and 0.1% for non-invasive SPMs); four additional patients, reported as having a SPM, were excluded, after central review of the data, either due to a previous history of malignancy or because of the evidence of a pre-existing tumour other than MM at the time of study entry. The median age at the time of SPMs development is 72 years (range 61-92), and the median time from trial entry to development of SPMs is 11 months (range 2.1-27.0). The most common SPMs reported were squamous cell carcinoma (4 pts, 2 invasive and 2 non invasive), breast cancer (3 pts), colon cancer (2 pts) and prostate cancer (2 pts). No haematological SPM has so far been reported. One patient, treated according to the intensive arm with LEN both as induction and maintenance, was reported as having a suspect myelodysplasia (MDS) due to anaemia and thrombocytopenia 2.7 months after entering the maintenance randomisation. No clear histological sign of MDS was found and the values improved after stopping maintenance treatment; these data fit with treatment related toxicity and not with the development of a MDS, and the patient was excluded from this analysis. Ten out of 17 SPMs developed during maintenance treatment or follow up phase, with 7 patients having received LEN maintenance. Median time from maintenance randomisation to SPMs development is 7 months (range 2-20.6 months). The remaining 7 were diagnosed during or immediately after induction. About half of the patients (8/17) were randomised to receive LEN induction; 3 patients received LEN both as induction and as maintenance. Interestingly only one of those 3 pts had been treated according to the intensive arm. With a median follow up of 1.36 years the estimated incidence rate at 1 and 2 years are 0.70% (95% CI .40-1.22)and 1.17% (95% CI .70-1.96) respectively (Figure 1). Conclusions Our data do not confirm previous findings of an excess risk of SPMs in association with the use of LEN and HDM in presenting patients, with 12/17 pts developing SPMs treated on the non intensive pathway that does not contain HDM. Most importantly only 0.4% of the patients enrolled within the intensive pathway developed a SPM, with only 2 of them receiving LEN maintenance. Longer follow up will help to further elucidate the risk of LEN associated SPMs. On behalf of the NCRI Haemato-Oncology subgroup Disclosures: Brioli: Celgene: Honoraria.

Abstract Background: With the advent of immunomodulatory agents (IMiDs), proteasome inhibitors (PIs) and, more recently, anti-CD38 monoclonal antibodies (mAbs), prognosis of patients with multiple myeloma (MM) has improved considerably. Unfortunately, even with these 3 major MM drug classes, most patients ultimately relapse and require further therapy. There remains an incomplete understanding of how patients who have received extensive therapy and with relapsed/refractory multiple myeloma (RRMM) are treated in routine clinical practice, as no standard-of-care exists for these patients, and what the outcomes are in this real-world setting. Objective: This study aims to evaluate the outcomes of patients with triple-class (IMiD, PI and anti-CD38 mAb) and triple-line exposed RRMM using real-world data from patients in Belgium. Methods: A multicenter, observational study, involving 7 non-academic and academic Belgian centers, was conducted based on a retrospective chart review of adult RRMM patients who started subsequent treatment from March 2017 through May 2021 after having received ≥3 lines of therapy including at least an IMiD, a PI, and anti-CD38-directed therapy (tri-exposed). Data were captured in an electronic case report form (Castor EDC). Patients with an ECOG performance status of ≥2, who received prior CAR-T treatment or prior BCMA-targeted therapy, or with a known active or prior history of CNS involvement (or with clinical signs thereof), were excluded. All treatment lines initiated after becoming eligible were used in the analysis. Specifically, all treatment lines for patients meeting the eligibility criteria more than once in their entire follow-up were included as separate observations, with date of treatment initiation as specific baseline for each treatment line. Cox proportional hazards models were fitted to explore the prognostic value with Overall Survival (OS), Progression Free Survival (PFS), and Time to Next Therapy (TTNT). Results: A total of 112 patients with 237 eligible treatment lines were included in the analysis; median follow-up was 16.6 months. In 45% of the initiated treatment lines, patients were refractory to 4 or 5 therapies, 62% had received ≥5 prior lines, 22% had extramedullary disease and in 48% of observations the time to progression in prior line was shorter than 4 months. After patients became tri-exposed, more than 50 unique treatment regimens were initiated, with the following being the most common: carfilzomib + dexamethasone (14%), pomalidomide + dexamethasone + chemotherapy (8%), and ixazomib + lenalidomide + dexamethasone (6%). Additionally, 4% of included observations were exposed to anti-BCMA agents. Overall, the following treatment classes were the most frequently started: PI only (19%), PI + IMiD combinations (17%), and regimens including anti-CD38 antibodies (15%). Median OS was 9.79 months [95% CI: 7.79; 12.22], median PFS was 3.42 months [95% CI: 2.79; 4.27], median TTNT was 3.61 months [95% CI: 3.09; 4.57]. Higher refractory status (p&lt;0.001), being male (p=0.001), older age (p&lt;0.001), shorter duration of prior lines (p&lt;0.001), shorter time to progression in prior line (p=0.025), and higher LDH levels (p&lt;0.002) were prognostic for worse outcomes for both OS (Figure 1) and PFS. Conclusions: This retrospective chart review of patients with tri-exposed RRMM in Belgium shows that real-world outcomes in terms of OS, PFS and TTNT are poor for these patients, with a median OS of &lt;10 months. A wide variety of treatment regimens used in clinical practice confirm the absence of a clear standard-of-care in this patient population. The literature also confirms that these poor outcomes observed in Belgium, for this subset of MM patients, are similar in other countries. These real-world data highlight the high unmet medical need in this patient population and critical need for new and effective treatment options. MD and MCV contributed equally to this work.

The TT approach has significantly improved the outcome of multiple myeloma (MM) by combining new drugs with a regimen that comprises induction, tandem autologous stem cell transplantation (ASCT), consolidation and maintenance. However, a group of 15% of patients with high risk multiple myeloma (HRMM) have derived little benefit despite similar response rates to induction chemotherapy and ASCT when compared to low risk MM. The poor outcome of HRMM is explained by early relapse post ASCT resulting in a short progression free survival (PFS) with only 15-20% of patients surviving long-term. Daratumumab (Dara) is a human IgG1k anti-CD38 monoclonal antibody that has shown favorable results in early single-arm studies and more recently in phase III studies for relapsed/refractory and newly diagnosed MM. In TT7, we introduced Dara during all phases of therapy, including immune consolidation early post ASCT, to improve responses rate and PFS in HRMM. Methods. Patients had newly diagnosed HRMM as defined by high risk cytogenetic abnormalities, presence of extramedullary disease, >3 focal lesions on CT-PET, elevated LDH due to MM, or ISS II/III with cytogenetic abnormality. Dara (16mg/kgx1) was added to induction with KTD-PACE (carfilzomib, thalidomide, dexamethasone; and four-day continuous infusions of cisplatin, doxorubicin, cyclophosphamide, etoposide). Conditioning for tandem autologous stem cell transplantation (ASCT) was with fractionated melphalan (50mg/m2x4) (fMEL) based on prior observations that patients with adverse cytogenetics fare better with fMEL rather than single high dose MEL200mg/m2.In the inter tandem ASCT period immunological consolidation with Dara (16mg/kg) alone for 2 doses was followed by Dara (16mg/kg) on day 1 combined with K (36mg/m2) and D (20mg) weekly for 2 cycles. DaraKD was administered to avoid treatment free periods allowing for myeloma regrowth. The 2nd ASCT was followed by further immunological consolidation with Dara (16mg/k) for 2 doses, and maintenance therapy for 3 yrs with 3-months block of alternating Dara-KD (dara 16mg/kg day 1; K 36mg/m2 and dex 20mg weekly) and Dara-lenalidomide (R)D (dara 16mg/kg day 1; R 15mg day 1-21 q28 and D 20mg weekly). Results. TT7 enrolled 43 patients thus far. The median follow-up was 11 months (range: 1-22). The median age was 61 yrs (range 44-73). Sixteen patients were ≥65 yrs (37.2%). A mean of 29.4x106 CD34+ cells/kg (range: 4.6-86.4) were collected. 36 patients completed ASCT #1 (83.7%) and 18 (41.9%) ASCT #2, whilst 14 patients have proceeded to the maintenance phase. R-ISS II/III or metaphase cytogenetic abnormalities were present in 85.1 and 58.1% of patients, respectively. Elevated LDH or >3FL on CT-PET were noted in 30 and 41.8%. The 1-yr cumulative incidence estimates for reaching VGPR and PR were 87 and 83%, respectively. A CR or sCR was achieved in 68 and 46%. The 1-yr estimates of PFS and OS were 91.6 and 87.2%. 40 subjects are alive, whilst 5 progressed on study therapy and 3 subsequently died. 38 patients are progression free at the time of reporting. Dara was well-tolerated and no subjects discontinued therapy due to dara-related side effects. The CR and sCR rates compared favorably to the predecessor HRMM TT5 protocol where CR and sCR rates were 59 and 27%. Conclusion. The early results of TT7 point to increased response rates of HRMM to a dara-based TT regimen with especially higher rates of CR and sCR. Longer follow-up is required to determine if these early results translate into superior PFS and OS.

Abstract Abstract 3859 Poster Board III-795 The initial results of the pivotal, international, phase III VISTA trial demonstrated the superiority of bortezomib (Velcade®) plus melphalan–prednisone (VMP) versus MP alone across all efficacy end points, including overall survival (OS), in previously untreated multiple myeloma (MM) patients ineligible for high-dose therapy (San Miguel et al, N Engl J Med 2008). We conducted a planned updated survival analysis of VISTA after a median >3 years of follow-up and with the majority of patients having received subsequent therapy. We confirmed the previously demonstrated OS benefit of VMP versus MP, examined the use of subsequent therapy and its efficacy following VMP and MP, and evaluated the survival of patients who had received subsequent therapy. Patients were randomized to receive nine 6-week cycles of VMP (N=344; bortezomib 1.3 mg/m2, d 1, 4, 8, 11, 22, 25, 29, 32, cycles 1–4, d 1, 8, 22, 29, cycles 5–9; melphalan 9 mg/m2 d 1–4, prednisone 60 mg/m2, d 1–4, all cycles) or MP (N=338) alone. Response was assessed using EBMT criteria with central laboratory M-protein analysis. After disease progression, patients were followed for survival and subsequent therapy, including investigator-assessed best response to subsequent therapies. The median age of patients was 71 years, 30% were aged ≥75 years, 34% had ISS stage III MM, and 33% had β2-microglobulin >5.5 mg/L. After median follow-up of 36.7 months, there was a 35% reduced risk of death with VMP vs MP (hazard ratio [HR] 0.653, p=0.0008); median OS was not estimable vs 43.1 months, and 3-year OS rates were 68.5% vs 54.0% with VMP vs MP, respectively. This OS benefit was seen consistently across patient subgroups predefined by baseline characteristics. Within the VMP arm, OS was longer among patients aged <75 vs ≥75 years (HR 1.664, p=0.011; 3-year OS: 74.1% vs 55.5%); by contrast, there were no significant differences, although there were trends to longer OS among patients with creatinine clearance ≥60 versus <60 mL/min (HR 1.291, p=0.238; 3-year OS: 74.5% vs 63.1%) and patients with standard- vs high-risk cytogenetics (HR 1.346, p=0.399; 3-year OS 71.6% vs 56.1%). At data cut-off (16 March 2009), 178 (52%) VMP and 233 (69%) MP patients had received subsequent therapy; median time to subsequent therapy (28.1 vs 19.2 months, HR 0.527, p<0.0001) and median treatment-free interval (17.6 vs 8.4 months, HR 0.543, p<0.0001) were superior with VMP vs MP. Receipt of and response to subsequent bortezomib-, thalidomide-, and lenalidomide-based therapy are summarized in the Table. Median survival from start of subsequent therapy following VMP and MP was 30.2 vs 21.9 months (HR 0.815, p=0.21) among all patients receiving subsequent therapy. This updated analysis of VISTA confirms that VMP results in significantly longer OS compared with MP, despite 50% of MP patients being rescued with bortezomib-based therapy in the relapsed setting. VMP treatment used upfront appears more beneficial than treating with conventional agents and saving bortezomib- and other novel-agent-based treatment until relapse. Subsequent therapies appeared similarly effective in the VMP and MP arms, with our analysis also demonstrating the benefit of retreatment with bortezomib-based therapies following VMP. In addition, post-relapse survival among all patients receiving subsequent therapy appeared longer following VMP, indicating that frontline bortezomib use does not induce more resistant relapses.

Abstract Abstract 623 Background: Although a meta-analysis has suggested that a consistent PFS benefit is seen with maintenance thalidomide therapy in multiple myeloma (MM) patients, the impact on OS remains unclear (Hicks LK, et al. Cancer Treat Rev 2008;34:442-452). This could be due to a lack of effect, differing biological subgroups in relatively small studies with short follow-up, or lack of effective relapse treatment. Aims: The study was set up to evaluate the effect of thalidomide maintenance therapy in newly diagnosed MM patients aged ≥ 18 years with OS and PFS as end points, and to examine differential effects in fluorescence in situ hybridization (FISH) identified molecular subgroups. Methods: Following induction treatment in an intensive pathway for younger fitter patients and a non-intensive pathway for the remaining patients, eligible patients were randomized to open-label thalidomide maintenance until progression (50 mg/day escalating to 100 mg/day after 4 weeks assuming good tolerance) or no maintenance. Patients of all ages were included in the randomization. FISH was performed using standard approaches. Adverse FISH groups were defined as any of t(4;14), t(14;16), t(14;20), 1q+, 17p−, or 1p32− (in the intensive pathway only); the remainder were defined as favorable. Results: Overall, 820 patients were eligible of which 818 were evaluable. Median patient age was 65 years (range, 31−89). Median follow-up from maintenance was 38 months (range 12−66 months). Median time on maintenance was 7 months (range 0−50 months). Maintenance thalidomide significantly improved PFS, with a difference between the curves of 13% (95% confidence interval [CI] 6%−20%) established by 24 months and maintained till the current maximum follow-up at 66 months (hazard ration [HR] 1.36; 95% CI 1.15−1.61; logrank P < 0.001). However, in the initial analysis there was no apparent impact on OS (P = 0.40). These findings were consistent regardless of prior intensive or non-intensive induction treatment. At 66 months follow-up, a PFS benefit was seen in the favorable FISH group (P = 0.004) with no effect on OS (P = 0.6). In the adverse FISH group there was no effect on PFS (P = 0.48) and a negative effect on OS (P = 0.009). Subsequently, we evaluated the effect of relapse treatment on outcomes and used this data in a mathematical model to determine if OS benefit would have accrued from the prolonged PFS if all patients had received effective treatment at relapse. A total of 523 patients have progressed to date and of these, 47% received thalidomide as initial relapse treatment (either as a single agent or in combination), 30% received novel agents (either bortezomib or lenalidomide), and 27% received alkylating agents or steroids. Median survival after progression was significantly worse in patients who received thalidomide maintenance than those who did not (P < 0.005); this could, at least partly, be attributed to patients who received thalidomide at progression. In those patients, the median OS after progression was significantly greater in the no maintenance group versus the thalidomide maintenance group (P = 0.004). Among patients treated with novel agents at progression, prior thalidomide maintenance therapy had no impact on OS and these patients were effectively salvaged. The mathematical model employed to examine the effect of effective salvage therapy at progression suggested that a significant survival benefit of 5.5% at 3-years in favor of thalidomide maintenance would have accrued if all patients had received effective therapy at progression (HR 0.77; 95% CI 0.60–0.99; P = 0.04). Next, we examined whether continuous thalidomide therapy was associated with a consolidation or maintenance effect. Upgrading of response with thalidomide maintenance was not common. Importantly, there was no difference in response over time between maintenance therapy and no maintenance. In contrast to what has been reported previously, these findings suggest a maintenance effect. Conclusions: Maintenance thalidomide significantly improves PFS and if effective relapse treatment is available this translates into an OS advantage. The median duration of maintenance thalidomide therapy of 7 months in the present study was short. The clinical impact of maintenance would be improved if patients could remain on therapy for longer, suggesting that the use of other agents such as lenalidomide, with better tolerability profiles, may produce better results. Disclosures: Off Label Use: THALOMID (thalidomide) in combination with dexamethasone is indicated for the treatment of patients with newly diagnosed multiple myeloma.

Abstract Abstract 478 Background: The US community-based, phase 3b randomized, open-label, multicenter UPFRONT trial compares the efficacy and safety of three bortezomib (VELCADE®, Vc)-based regimens, VcD (Vc-dexamethasone), VcTD (Vc-thalidomide-dexamethasone), and VcMP (Vc-melphalan-prednisone), followed by weekly Vc maintenance, in elderly, newly diagnosed, transplant-ineligible multiple myeloma (MM) patients. This is the first phase 3 study of VcD and VcTD in this patient population. Methods: Patients with symptomatic, measurable MM were randomized (1:1:1) to receive 49 weeks of therapy: 24 weeks (eight 21-day cycles) of induction with VcD, VcTD, or VcMP (VcD: Vc 1.3 mg/m2, days 1, 4, 8, 11; D 20 mg, days 1, 2, 4, 5, 8, 9, 11, 12 [cycles 1–4]), days 1, 2, 4, 5 [cycles 5–8]); VcTD: Vc as before; T 100 mg/day, days 1–21; D as before); VcMP: Vc as before; M 9 mg/m2 and P 60 mg/m2, days 1–4, every other cycle), followed by 25 weeks (five 35-day cycles) of maintenance with weekly Vc 1.6 mg/m2, days 1, 8, 15, 22. Patients in the VcTD arm received concomitant prophylaxis with aspirin, full-dose warfarin, or low-molecular weight heparin unless medically contraindicated. The primary endpoint was progression-free survival (PFS); secondary endpoints included overall response rate (ORR), complete response (CR)/near CR (nCR) and very good partial response (VGPR) rates, overall survival (OS), and safety. Best confirmed responses were assessed by investigators per modified International Myeloma Working Group (IMWG) criteria. Adverse events (AEs) were graded by NCI-CTCAE v3.0. PFS and OS were estimated by Kaplan–Meier methodology. For the first time, we report results from the entire cohort of 502 randomized patients (VcD, n=168; VcTD, n=167; VcMP, n=167), who completed up to a maximum of 13 cycles of treatment. Results: Patients in the VcD, VcTD, and VcMP arms had a median age of 74.5, 73.0, and 72.0 years, respectively, and 71%, 62%, and 72% had ISS stage II/III disease. Patients received a median of 8 (VcD), 6 (VcTD), and 7 (VcMP) treatment cycles; 50%, 38%, and 42% of patients, respectively, received Vc maintenance. Response and safety data are summarized in the table. All three Vc-based induction regimens exhibited substantial activity, with ORR of 73% (VcD), 80% (VcTD), and 69% (VcMP) during the treatment period. After a median follow-up of 21.8 months, no significant difference in PFS was observed between the treatment arms; median PFS was 13.8 months (VcD), 14.7 months (VcTD), and 17.3 months (VcMP), respectively (Figure). 1-year OS estimates were 87.4% (VcD), 86.1% (VcTD), and 88.9% (VcMP). Rates of grade ≥3 AEs, serious AEs (SAEs), and discontinuations due to AEs during the treatment period were highest for the VcTD arm. The most common grade ≥3 AEs across all three arms during the treatment period were neuropathy peripheral (23%), fatigue (10%), and diarrhea (9%). Grade ≥3 pneumonia was reported in 10% (VcD), 6% (VcTD), and 6% (VcMP) of patients. AEs of deep vein thrombosis/pulmonary embolism were reported in 8% (VcD), 7% (VcTD), and 2% (VcMP) of patients. Compared with rates during induction, Vc maintenance produced little additional toxicity; across all three treatment arms, only 5% of patients experienced grade ≥3 peripheral neuropathy during cycles 9–13. One second primary malignancy (lung neoplasm) was reported in the VcMP arm. Conclusions: VcD, VcTD, and VcMP induction followed by weekly Vc maintenance produced similar activity in elderly, newly diagnosed, transplant-ineligible MM patients. Patients in the VcD doublet arm appear to have similar long-term outcomes to patients in the VcTD and VcMP triplet arms.

Abstract Abstract 452FN2 Background: In ENESTnd, pts treated with nilotinib demonstrated higher and faster rates of major molecular response (MMR, ≤ 0.1% BCR-ABLIS), deeper molecular response (MR4, ≤ 0.01%IS and MR4.5, ≤ 0.0032%IS), and complete cytogenetic responses (CCyR) along with significantly lower rates of progression to AP/BC and fewer CML-related deaths compared with imatinib by 12 and 24 mo. Here, we report data with a minimum follow-up of 24 mo; however, efficacy and safety data based on considerably longer follow-up of ≥ 36 mo will be presented. As demonstrated in IRIS and other imatinib trials, most pts who progress on imatinib do so within the first 3 years of therapy. Thus, this 36-mo update of ENESTnd will be important to further verify the benefits of nilotinib in newly-diagnosed pts. Methods: 846 adult pts with newly-diagnosed Ph+ CML-CP were randomized to nilotinib 300 mg twice daily (BID) (n = 282), nilotinib 400 mg BID (n = 281), or imatinib 400 mg once daily (QD) (n = 283). MMR, MR4, MR4.5, time to progression to AP/BC on treatment, progression-free survival (PFS) on treatment, and overall survival (OS) were evaluated. Results: By 24 mo, both doses of nilotinib demonstrated significantly higher rates of MMR, MR4, and MR4.5 vs imatinib (Table). Nilotinib-treated pts achieved median BCR-ABLIS levels of 0.09% (300 mg BID) and 0.10% (400 mg BID) by 12 mo, while this level of reduction was not observed before 24 mo on imatinib. More pts with CCyR achieved MMR at 12 and 24 mo with either dose of nilotinib vs imatinib (Table). Regardless of Sokal risk, rates of MMR and MR4.5 were higher for nilotinib at both doses vs imatinib (Table). Progression to AP/BC (excluding clonal evolution [CE]) on treatment was significantly lower for nilotinib vs imatinib (2 pts and 3 pts with nilotinib 300 mg BID [P = .0059] and 400 mg BID [P =.0196]), respectively vs 12 pts with imatinib). After achieving CCyR, 4 pts treated with imatinib progressed to AP/BC and 2 pts treated with nilotinib 400 mg BID progressed after achieving both CCyR and MMR (1 also achieved MR4). No pt who achieved MR4.5 progressed at any time. All but 1 pt who progressed to AP/BC on treatment were in the intermediate and high Sokal risk groups; 1 pt treated with nilotinib 400 mg BID progressed in the low Sokal risk group who had an E255V mutation at progression. When considering progression events of pts after discontinuation of treatment, an additional 7, 2, and 6 events (excluding CE) were observed with nilotinib 300 mg BID, nilotinib 400 mg BID and imatinib, respectively. Twice as many pts had emergent mutations on imatinib (n = 20) vs nilotinib (n = 10 on 300 mg BID; n = 8 on 400 mg BID). At 24 mo, OS remained similar in all groups, but there were fewer CML-related deaths in both nilotinib 300 mg BID (5 pts) and nilotinib 400 mg BID (3 pts) arms vs imatinib (10 pts). Both drugs were well tolerated and few new adverse events (AEs) and lab abnormalities were observed between 12- and 24-mo of follow-up. Nilotinib 300 mg BID had the fewest discontinuations due to AEs/lab abnormalities (9% vs 13% and 10% with nilotinib 400 mg BID and imatinib, respectively). Conclusions: With a minimum follow-up of 24 mo, nilotinib continued to demonstrate superiority vs imatinib with faster and deeper molecular responses and a significantly decreased risk of progression. These data support the use of nilotinib as a standard of care option in newly-diagnosed adult pts with Ph+ CML-CP.

Abstract Background Carfilzomib (Cfz) synergizes with lenalidomide and dexamethasone (Len-dex) to provide impressive response rates as upfront treatment of multiple myeloma (MM) (Jakubowiak et al 2012). The addition of clarithromycin to Len-dex has shown superior time to progression compared to Len-dex alone (Gay et al 2010). We hypothesized that sequential treatment with Cfz-dex and BiRD would lead to enhanced efficacy, response duration, and tolerability. We thus tested a sequential approach of upfront carfilzomib / dexamethasone, consolidation with BiRd, and lenalidomide maintenance to evaluate overall response and safety as first line therapy for MM. Methods Twenty-four patients (pts) with symptomatic untreated MM were enrolled in a single institution study to evaluate the efficacy and tolerability of Car-BiRd. Car-BiRd therapy is: Cfz IV over 30 minutes on Days 1, 2, 8, 9, 15, 16 of a 28-day cycle at a dose of 20mg/m2 on days 1, 2 of the 1st cycle only and 45mg/m2 for each successive dose thereafter and dex 40mg on D1, 8, 15, 22. Cfz-dex was continued until plateau in disease response defined as unchanged M-protein for 2 cycles. Elective autologous stem cell collection was then performed per physician and patient discretion and consolidation with BiRd initiated. Transplant ineligible pts proceeded directly to BiRd. BiRd is: Clarithromycin 500mg BID, lenalidomide 25mg daily on D1-21, and dex 40mg daily D1, 8, 15, 22 of 28-day cycle. Therapy was continued until a 2nd plateau in disease response after which lenalidomide maintenance at a dose of 10mg daily D1-21 of 28 day cycle was continued until disease progression or intolerability. Results 24 pts have currently been enrolled; 23 have completed at least 1 cycle of therapy and were evaluable for response. Sixteen pts (67%) harbored high-risk cytogenetics, as defined by the presence of one or more of the following on iFISH: del 17p, gain 1q, del 1p, t(4;14), t(14;16), or complex karyotypic abnormalities. Median study follow-up was 30.8 weeks (range 4.5-62.2). Response to the Car-BiRD regimen was: overall response rate (ORR) 87%, stringent complete response (sCR) 13%, very good partial response (VGPR) 48%, partial response (PR) 26%, stable disease (SD) 13%. Maximum response to the Cfz-dex induction was: ORR 87%, sCR 9%, VGPR 39%, PR 35%, SD 13%. Median time to PR and maximum response with Cfz-dex was 2 cycles (range 1-2) and 4 cycles (range 1-5) respectively. Median M-spike percentage decrease with Cfz-dex was 92% (range 13-100%). Twelve pts thereafter received BiRD consolidation with 5 pts (41%) further decreasing the M-spike by a median of 8% (range 1-45%). A median of 3 cycles (range 2-7) of BiRD was given until a 2nd response plateau was achieved. Seven pts subsequently received lenalidomide and all have maintained their response after a median of 5 cycles (range 1-8) of follow-up. Seven pts (30%) have come off study, 2 (8%) secondary to disease progression (1 during Car-Dex and 1 during BiRD) and 5 pts (22%) due to toxicity (2 pts due to Grade III renal failure, both attributable to Cfz, and 2 pts due to Grade III CHF during Cfz-Dex, 1 attributable to Cfz; 1 pt with Grade III Thromboembolic event during BiRD, attributable to Len-dex). Discussion This is the first prospective study evaluating the response to induction Cfz/Dex in treatment-naïve MM. Cfz/Dex therapy appears safe and effective in newly diagnosed myeloma patients. Responses deepen with subsequent IMiD(R)-based consolidation and maintenance. Toxicities due to each component of the regimen were manageable. The ORR of 87% and rate of VGPR or better of 61% in group with a high percentage of unfavorable cytogenetics compares favorably to similar studies using 1st generation proteasome inhibitor combinations, and may continue to improve with longer study follow-up.
