Phase Iii Trial

Abstract Background: SWOG S0777, a randomized phase III trial, compared bortezomib, lenalidomide and dexamethasone (VRd) with lenalidomide and dexamethasone (Rd). The primary end point was progression-free survival (PFS) using a pre-specified one-sided stratified log rank test at a significance level of 0.02. The stratification factors were International Staging System (ISS) stage (I, II or III) and intent to transplant (yes or no), among a total of 6 strata. Overall response rate (ORR), overall survival (OS) and safety were secondary end points. Results of the primary analysis of this trial were published in Lancet (2016, Volume 389, Issue 10068, 519 - 527). Methods: This updated analysis includes 460 patients evaluable for survival endpoints: 225 eligible and analyzable patients were randomized to Rd and 235 patients to VRd. Rd patients received lenalidomide 25 mg/day on days 1-21 and dexamethasone 40 mg/day on days 1, 8, 15 and 22 of a 28-day cycle. VRd patients received lenalidomide 25 mg/day on days 1-14 and dexamethasone 20/mg/day on days 1, 2, 4, 5, 8, 9, 11 and 12 plus bortezomib 1.3 mg/m2 IV push on days 1, 4, 8 and 11 of a 21-day cycle. All patients received aspirin 325 mg/day and VRd patients received VZV prophylaxis per institutional standard. The 6-month induction was six 28-day cycles of Rd and eight 21-day cycles of VRd followed by Rd maintenance for all patients until progression, unacceptable toxicity or withdrawal of consent. Results: Between 2008 and 2012, 525 patients from 48 institutions were randomized. Patient data have been rigorously updated for this analysis based upon a May 15, 2018 datalock. The median follow up is now 84 months (7 years). The median PFS is 41 months for VRd and 29 months for Rd: stratified hazard ratio (96% Wald Confidence Interval) was 0.742 (0.594, 0.928) and one-sided stratified log-rank P-value 0.003 (see Figure 1). The median OS for VRd is still not reached with median OS for Rd being 69 months: stratified hazard ratio (96% Wald Confidence Interval) was 0.709 (0.543, 0.926) and stratified two-sided P-value was 0.0114 (see Figure 2). The impact of age was assessed in several ways including using 3 cutoffs (<65 years; 65-75 years; >75 years) and multivariate cox proportional hazards regression analyses adjusted for age. As in prior analyses, both PFS and OS were improved with VRd versus Rd adjusting for age (P-values: 0.013 [PFS]; 0.033 [OS])). Depth of response was assessed incorporating new serial data and additional bone marrow results. The CR plus VGPR was 74.9% for VRd versus CR plus VGPR of 53.7% for Rd (P-value 0.006 for response differences using a stratified Cochran-Mantel- Haenszel analysis). The median duration of lenalidomide plus dexamethasone maintenance was 17.4 months. The number of second cancers was 19/235 (8%) with VRd and 16/225 (7%) with Rd. Conclusion: The addition of bortezomib to lenalidomide dexamethasone for induction therapy in previously untreated myeloma results in a statistically significant and clinically meaningful improvement in PFS as well as better OS with follow up of 7 years. VRd had an acceptable safety and tolerability profile and continues to represent an appropriate standard of care irrespective of age.

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 Background: Lenalidomide with dexamethasone (Rd) is a standard of care for patients with previously untreated multiple myeloma. SWOG S0777, a randomized phase III trial, has compared Rd with bortezomib, lenalidomide and dexamethasone (VRd). The primary end point is progression-free survival (PFS) using a pre-specified one-sided stratified log rank test at a significance level of 0.02. The stratification factors are International Staging System (ISS) stage (I, II or III) and intent to transplant (yes or no), a total of 6 strata. Overall response rate (ORR), overall survival (OS) and safety are secondary end points. Methods: This analysis includes 474 patients evaluable for survival endpoints: 232 patients were randomized to Rd and 242 patients to VRd. Rd patients received lenalidomide 25 mg/day on days 1-21 and dexamethasone 40 mg/day on days 1, 8, 15 and 22 of a 28-day cycle. VRd patients received lenalidomide 25 mg/day on days 1-14 and dexamethasone 20/mg/day on days 1, 2, 4, 5, 8, 9, 11 and 12 plus bortezomib 1.3 mg/m2 IV push on days 1, 4, 8 and 11 of a 21-day cycle. All patients received aspirin 325 mg/day and VRd patients received HSV prophylaxis per institutional standard. Induction was six 28-day cycles of Rd and eight 21-day cycles of VRd followed by Rd maintenance for all patients until progression, unacceptable toxicity or withdrawal of consent. Initial analyses utilized the pre-specified one-sided stratified log rank test. Results: Data are presented for VRd followed by Rd throughout. Between 2008 and 2012, 525 patients from 48 institutions were randomized. Fifty-one patients, 29 randomized to Rd and 22 randomized to RVd, were ineligible for the following reasons: missing, insufficient or early or late baseline labs (40); not meeting requirements of measurable disease (6); inadequate marrow function (1); inadequate creatinine clearance (1); prior malignancy (1); prior therapy (1); and more than 2 weeks of prior steroid therapy (1). The pre-specified significance level of 0.02 was reached in the log rank testing. The stratified hazard ratio (HR) was 0.742 (96% Wald confidence interval: 0.579, 0.951), and the one-sided stratified log rank p-value for PFS (VRd vs. Rd) was 0.0066. The OS was improved for VRd vs. Rd with HR = 0.666; two-sided log-rank p-value = 0.0114. The PFS and OS survival charts are displayed below. Median PFS was 43 months (VRd) versus 31 months (Rd). Median OS was not reached (VRd) versus 63 months (Rd). Patient characteristics were well-matched between VRd and Rd with the exception of fewer women (37% vs. 47%: P = 0.033) and fewer older patients (≥ 65 years 38% vs. 48%: P = 0.042) receiving VRd. With univariate Cox regression analysis correlates of better PFS/OS were: use of VRd (HR 0.72/0.65; P = 0.006); hemogoblin ≥10 g/dl (HR 1.17/1.43; P = 0.2/0.026) and lower ISS disease stage (HR 1.35/1.98; P = 0.014/< 0.001). The ORR for VRd was 71.07% versus 63.79% for Rd. The adverse events by CTC category and toxicity category were fairly well balanced. The most common hematologic adverse events (≥ Grade 3 and at least possibly attributable to therapy) were low hemoglobin (RVd=13%; Rd=16%), leukopenia (RVd=14%; Rd=16%), lymphopenia (RVd=23%; Rd=18%), neutropenia (RVd=19%; Rd=21%), and thrombocytopenia (RVd=18%; Rd=14%). The most common non-hematologic adverse events (≥ Grade 3 and at least possibly attributable to therapy) were: fatigue (RVd=16%; Rd=14%), sensory neuropathy (RVd=23%; Rd=3%), hyperglycemia (RVd=7%; Rd=11%), thrombosis/embolism (RVd=8%; Rd=9%), hypokalemia (RVd=9%; Rd=6%), muscle weakness (RVd=7%; Rd=4%), diarrhea (RVd=8%; Rd=2%), and dehydration (RVd=8%; Rd=2%). As expected ≥ Grade 3 neuropathy was more frequent with VRd (24% vs. 5%: P < 0.0001). Sixteen patients experienced a second primary malignancy, 7 (3%) on VRd and 9 (4%) on Rd. Conclusion: The addition of bortezomib to lenalidomide dexamethasone for induction therapy in previously untreated myeloma results in a statistically significant and clinically meaningful improvement in PFS as well as better OS. VRd had an acceptable safety and tolerability profile despite increased neurotoxicity and represents a potential new standard of care.

Abstract The plasma cell proliferative index (PCPI) provides an insight into plasma cell biology in plasma cell disorders. It recognizes cells that are actively synthesizing DNA and gives an indication of the proliferative rate of the malignant plasma cells.The PCPI has been shown to be a prognostic tool in patients with multiple myeloma and amyloidosis. We conducted a retrospective review analyzing the prognostic impact of PCPI in 306 patients with smoldering multiple myeloma (SMM). The median age was 66 (56-73) years and 61% (n=186) were males. The median follow-up for the entire cohort was 10.2 years (95% confidence interval: 9.0-10.9). One-hundred sixty-nine (55%) patients were alive at the time of study analysis while 118 (39%) had progressive disease. The median time to progression was 5.9 years (95% confidence interval: 4.8-8.2). Symptomatic events at the time of progression included anemia in 41% (n=48), bone complications in 37% (n=44), renal complications in 9% (n=11), hypercalcemia in 2% (n=2) and development of amyloidosis in 2% (n=2). Seventeen patients (14%) were categorized as having progression due to rapid progressive elevation in the serum free light chains (sFLC) and/or progressive increase in the size of their M-spike. The median time between the diagnosis and PCPI date was 0 months (interquartile range 0-1). An elevated PCPI was defined as a level >0.5%. Seventy-nine (26%) patients had an elevated PCPI. Patients with an elevated PCPI were significantly older (median age: 69 years for elevated PCPI vs 64 years for low PCPI (p= 0.008) and predictably had more proliferative disease with a higher rate of patients with bone marrow plasma cells >20% (48% for elevated PCPI vs 34% for low PCPI, p=0.03). An elevated PCPI predicted a shorter time to progression (TTP); median 3.0 years versus 7.1 years for those with a low PCPI (p= 0.0004). Within 24 months, the progression rate was significantly higher for patients with an elevated PCPI; 49% versus 20% (p<0.0001). We constructed two multivariable models using the conventional and recently proposed Mayo risk stratification tools. In both models, an elevated PCPI was an independent predictor of to multiple myeloma. PCPI is a valuable tool in risk stratifying patients with SMM and identifies patients with earlier progression who may benefit from closer follow up and consideration of early intervention trials.

Abstract Introduction: Multiple Myeloma (MM) is a clonal plasma cell malignancy, accounting for 10% of all hematological malignancies. Genetic analyses of large populations revealed that blood-specific somatic mutations in hematopoietic stem cells (HSCs) are commonly acquired during aging, a new entity labeled: clonal hematopoiesis of indeterminate potential (CHIP). We sought to determine the role of CHIP on survival of MM patients, specifically those receiving immunomodulator (IMiD) maintenance (Lenalidomide or Thalidomide) post autologous stem cell transplant (ASCT). Methods: We collected the cryopreserved, growth factor mobilized peripheral blood of 629 MM patients who underwent ASCT between 2003 and 2011 at the Dana-Farber Cancer Institute (DFCI). Then, we performed targeted next-generation sequencing using a 224-gene panel at a mean depth of coverage of 978X and ultra-low pass whole-genome sequencing at 0.1X to account for tumor contamination. We downloaded (dbGAP # phs000748.v6.p4) the whole-exome sequencing (WES) data of a cohort of 1144 newly diagnosed, untreated MM patients from the Multiple Myeloma Research Foundation (MMRF) Clinical Outcomes in MM to Personal Assessment of Genetic Profile (CoMMpass, NCT0145429) study (MMRC) and the WES data of a cohort of 205 newly diagnosed, untreated MM patients from the Broad Institute dataset. We analyzed their peripheral blood (average coverage of 108X) and tumor (average coverage of 107X) data separately, looking for the same CHIP genes included in our target bait panel. Results: The DFCI cohort had a median age of 58 years [range, 24-83] at time of ASCT and median follow up post ASCT of 8 years [range, 0.1-14.5]. 204 patients (32%) in the DFCI cohort had CHIP at time of ASCT. The most commonly detected mutated genes were DNMT3A, TET2, TP53, ASXL1 and PPM1D. 24 patients (3.8%) developed a second hematological malignancy at a median of 4 years [range, 1-10] post ASCT, half of whom had CHIP. Around 48% of the DFCI cohort received IMiDs as part of induction therapy. Different induction regimens had no effect on CHIP prevalence at time of ASCT. Around 56% of the DFCI cohort received IMiD maintenance, 22% of which received maintenance for at least 3 years [range, 0.06-12.8]. Among those who did not receive IMiD maintenance, patients with CHIP had worse progression free survival (PFS) (p-value < 0.001) and overall survival (OS) (p-value = 0.005). In patients receiving IMiD maintenance, having CHIP had no effect on PFS or OS. On the other hand, the MMRF cohort had a median age of 63 years [range, 27-93] and median follow up of 3.03 years [range, 0-5.9] from time of diagnosis. Around 52% of that cohort underwent ASCT and around 76% of those received IMiD maintenance with a median follow up of 2.7 years [range, 0-5.5] from time of ASCT. Furthermore, 200 patients of the MMRF cohort have follow-up samples of both tumor and peripheral blood that had targeted sequencing done by a 562-gene panel that included our genes of interest. Similarly, when studying the genomic results of 139 out of 1144 MMRF patients, as well as the 205 patients from the Broad Institute dataset, we detected CHIP in 25.6% of them and the top 5 most commonly mutated genes were similar to those of our cohort. Conclusion: CHIP is a common entity among MM patients, reaching a prevalence of up to 32%, that predicts a worse PFS and OS in those who do not receive IMiD maintenance therapy post ASCT. As expected, IMiD maintenance improves outcome in MM patients, with and without CHIP. In patients with CHIP, the use of IMiDs abrogated the deleterious effect imposed by CHIP to a point that outcome is identical to that of patients without CHIP. Figure Figure.

Abstract Abstract 4024 Background: The hypomethylating agents 5-azacytidine (Vidaza) and 5-aza-2′-deoxycytidine (Decitabine, DAC) are active in different MDS subtypes. Compared to other response predictors to DAC, prior MDS duration has received only limited attention (1, 2), with conflicting results. Based on our finding that long duration of MDS prior to DAC treatment may be a novel factor linked to a better outcome (1), we now assess its value in the phase III trial 06011 (DAC versus BSC [3]). Immediate enrolment after diagnosis was allowed in that trial, median MDS duration prior to randomization thus only 3 months (mths). Methods: Comparison of progression-free (PFS), AML-free (AMLFS) and overall survival (OS) according to MDS duration >= vs. <3 mths in 233 patients (pts) with higher-risk MDS (median age 70 years) randomized to DAC (n=119) or BSC (n=114). Comparisons by long-rank test and multivariate analyses by Cox regression (Performance Status [PS], cytogenetics and IPSS high risk N/Y) were performed retrospectively: MDS duration had not yet been known as possible stratification factor at time of study initiation, and the trial thus not been powered to detect significant differences with regard to this discriminator. Results: A better prognosis of patients with MDS duration >=3 vs <3 mths was observed in DAC arm (B vs A) and BSC arm (D vs C). Conversely, DAC yielded better results than BSC in each MDS duration group: <3 mths (A vs C) and >=3 mths (B vs D). In both arms (n=233), Mult. indicated that MDS duration (>=3 vs <3 mths) adjusted for treatment, PS, cytogenetics and IPSS group was an independent prognostic factor regarding PFS (HR=0.75, 95%CI 0.58–0.99), AMLFS (HR=0.68, 95%CI 0.51–0.90), and OS (HR=0.75, 95%CI 0.56–0.99). The tests for interaction treatment × duration of MDS were not significant for 3 endpoints: PFS (p=0.38), AMLFS (p=0.90), OS (p=0.67). Conclusion: In intermediate-2 and high-risk MDS pts, long duration from MDS diagnosis to start of DAC or BSC appeared to be associated with a better outcome. This finding is in sharp contrast to the adverse prognostic impact of antecedent disease duration in patients who received intensive chemotherapy (4). It is supported by a similar analysis of pts with AML from MDS treated on the 00331 DAC phase II multicenter trial: those with longer MDS duration prior to DAC also had better outcome (5). Application of this discriminator in the evaluation also of other DAC schedules and MDS treatments therefore appears warranted. References: 1. Wijermans et al., Ann.

Abstract Background High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) improves survival in multiple myeloma (MM). The introduction of novel agents challenged the role of ASCT at diagnosis. We conducted a multicenter 2X2 randomized trial comparing conventional chemotherapy plus lenalidomide with ASCT followed by maintenance with lenalidomide-prednisone (RP) or lenalidomide (R) alone in newly diagnosed young MM (NDMM) patients. Methods Eligible patients with NDMM ≤ 65 years were enrolled. All patients received Rd induction (four 28-day cycles of lenalidomide 25 mg day 1–21 and low-dose dexamethasone 40 mg day 1,8,15,22) followed by stem cell mobilization. Patients were randomized to receive consolidation with CRD [six 28-day cycles of cyclophosphamide (300 mg/m2 day 1,8,15), dexamethasone (40 mg days 1,8,15,22) and lenalidomide (25 mg days 1–21)] or MEL200-ASCT (melphalan 200 mg/m2 with stem-cell support). Patients were randomly assigned to receive subsequent maintenance with RP (28-day cycles of lenalidomide 25 mg days 1–21 plus prednisone 50 mg every other day) or R alone (28-day cycles of lenalidomide 25 mg days 1–21). Primary study endpoint was progression-free survival (PFS); secondary endpoints included safety, responses and overall survival (OS). Data cut off was May 30th, 2013. Results Three-hundred and eighty-nine patients were enrolled in the trial. Patient characteristics were well balanced between CRD (n=194) and MEL200-ASCT (n=195), and between R (n=195) and RP (n=194) arms. Median follow-up was 31 months. In the intent to treat (ITT) analysis, the median PFS was not reached with MEL200-ASCT and 28 months with CRD (the respective 3-year PFS was 60% vs. 38%, HR=0.62, 95%CI: 0.49-0.85, P=0.003). Median time from enrolment to maintenance was 14 months. In the population of patients eligible for maintenance, 2-year PFS from the start of maintenance was 73% for RP and 56% for R patients (HR= 0.57, 95%CI: 0.34-0.93; P=0.03). In the subgroup of patients who received MEL200-ASCT, 2-year PFS from the start of maintenance was 83% for patients who received RP and 64% for those who received R alone (HR=0.36 95%CI: 0.15-0.87, P=0.02). In the subgroup of patients who received CRD, 2-year PFS from the start of maintenance was 64% for patients who received RP and 47% for those who received R alone (HR=0.75, 95%CI: 0.40-1.39, P=0.36). At present, no differences in OS were noticed between patients randomised to received CRD or MEL200-ASCT, and between patients who received RP or R maintenance. As expected, the rates of grade 3-4 hematologic (85% vs. 26%, P<0.001) and non-hematologic (35% vs. 19%, P=0.003) adverse events (AEs) were higher in the MEL200-ASCT arm compared with the CRD arm. The main non-hematologic AEs were infections (18% vs. 5%, P=0.001) and gastrointestinal AEs (18% vs. 3%, P<0.001). Rates of grade 3-4 hematologic (8% vs. 7%, P=0.85) and non-hematologic (12% vs. 13%, P=0.88). AEs were similar in the RP and R arms. The main non-hematologic AEs in both RP and R groups were infections (3% vs. 3%). At present, 6 second primary malignancies and 3 cases of cutaneous basalioma have been reported. Conclusions MEL200-ASCT significantly prolonged PFS in comparison with CRD. At present no difference in OS was reported, this may be due to the low number of events and to the length of follow-up. The increase in toxicity with MEL200-ASCT did not adversely impact on efficacy. The addition of prednisone to lenalidomide maintenance significantly reduced the risk of progression in comparison with lenalidomide alone, without increasing the toxicity. Updated data with longer follow-up will be presented at the meeting.

Abstract BACKGROUND: Genomic aberrations and IGHV mutation status are established prognostic factors in CLL. With TP53, NOTCH1, SF3B1, ATM, MYD88, FBXW7, BIRC3 and POT1 recurrently mutated genes were found in CLL and were discussed to associate with disease characteristics and to affect therapy efficacy and outcome. METHODS: We assessed the incidence and impact of gene mutations in the COMPLEMENT1 trial (1st line Chl vs. O-Chl). Pretreatment samples were available from 376 patients (84.1%) and this cohort was representative of the full trial population. Mutations were analyzed by amplicon-based targeted NGS using Illumina Miseq for all coding exons (TP53, ATM, MYD88, FBXW7, BIRC3 and POT1) or hotspot exons (NOTCH1, SF3B1). Additionally, the exact variant frequency was determined. RESULTS: The incidences of gene mutations were: TP53 8.2%, NOTCH1 14.9%, SF3B1 14.1%, ATM 10.9%, MYD88 2.7%, FBXW7 3.5%, POT1 7.7%, and BIRC3 2.7%. Regarding baseline characteristics, we found significant associations: TP53mut with high ß2MG (p=0.01), 17p- (p<0.01), and unmutated IGHV (p=0.01); ATMmut with high WBC (p=0.02), and 11q- (p<0.01); MYD88mut with mutated IGHV (p=0.02); FBXW7mut with 17p- (p=0.02), and +12q (p<0.01). BIRC3mut was only present in IGHV unmutated cases (p<0.01), was more frequent in 11q- (p<0.01), +12q (p=0.05), and in cases with NOTCH1mut (p=0.05). POT1mut was more frequent in NOTCH1mut cases (p=0.02) without associations with any other baseline parameter. Regarding response to treatment, TP53mut was significantly associated with reduced ORR rate (p<0.01). CR rate was not correlated with mutations in the covered genes. At a median follow-up of 31.7 months, there were 249 (66%) events for PFS and 63 (16.8%) events for OS. O-Chl as compared to Chl resulted in significantly improved PFS (median 22.4 vs. 13.1 months, HR 0.54, p<0.01). In univariate analyses, TP53mut (HR 2.07, p<0.01), NOTCH1mut (HR 1.50, p=0.01) and SF3B1mut (HR 1.66, p=0.01) were associated with shorter PFS, whereas ATM and other candidate genes showed no association (ATMmut: HR 1.40, p=0.07). Analyzing both treatment arms separately, TP53mut had an impact on PFS with Chl and O-Chl treatment (HR 1.92, p=0.04 and HR 2.49, p<0.01). Notably, NOTCH1mut was associated with outcome in O-Chl only (HR 2.01, p<0.01 vs. HR 1.14, p=0.59) resulting in a reduced beneficial effect from the addition of Ofatumumab to Chlorambucil treatment. ATMmut and BIRC3mut mutations were only adverse prognostic factors with Chl monotherapy (ATMmut: HR 1.69, p=0.05 vs. HR 1.35, p=0.27; BIRC3mut: HR 2.84, p=0.04 vs. HR 0.99, p=0.99). OS was reduced significantly only in TP53mut cases (HR 3.69, p<0.01). Of note, none of the MYD88mut cases (n=10) had died within the follow-up period. To identify genomic factors of independent prognostic impact, we performed multivariable Cox regression analyses for PFS and OS including treatment arms, 11q-, +12q, 17p-, IGHV and all candidate gene mutations. For PFS, the following independent prognostic factors were identified: O-Chl (HR 0.46, p<0.01), 17p- (HR 3.14, p<0.01), 11q- (HR 1.57, p=0.01), unmutated IGHV (HR 1.43, p=0.02), TP53mut (HR 1.81, p=0.03), NOTCH1mut (HR 1.63, p<0.01) and SF3B1mut (HR 1.54, p=0.02). Regarding OS, only 17p- (HR 4.07, p<0.01), and unmutated IGHV (HR 1.81, p=0.05) were identified as independent adverse prognostic factors with TP53mut showing a trend (HR 2.14, p=0.10). CONCLUSION: We performed mutational analyses for the 8 most frequent mutated genes in CLL in the COMPLEMENT1 trial evaluating 1st line O-Chl against Chl. An independent prognostic impact was identified for TP53mut, NOTCH1mutand SF3B1mut regarding PFS. Notably, NOTCH1mut affected outcome mainly with O-Chl treatment, whereas ATMmut and BIRC3mut were associated with outcome with Chl monotherapy. In multivariate analysis for OS, none of the gene mutations, but the established parameters IGHV and 17p- had independent prognostic impact.

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 Background: Len maintenance after autoHCT has improved progression-free (PFS) and overall survival (OS). However, the role of additional interventions after autoHCT such as tandem autoHCT or triple therapy consolidation remains to be determined. Methods: This is a phase III clinical trial (NCT#01109004) of transplant-eligible patients (pts) with symptomatic MM <71 years of age within 12 months of initiating therapy and without prior progression who were randomly assigned 1:1:1 to receive melphalan 200mg/m2 autoHCT and 4 cycles of RVD consolidation (lenalidomide 15mg daily days 1-14, dexamethasone 40mg day 1,8 and 15, and bortezomib 1.3mg/m2 days 1,4,8 and 11 every 21 days) (ACM), versus tandem melphalan 200mg/m2 autoHCT (TAM) or versus a single autoHCT (AM). Randomization was stratified by disease risk (cytogenetic abnormalities - del13q by karyotype, del17q, t(4;14), t(14;16), t(14;20) and hypodyploid; or high beta-2 microglobulin) and center. All arms included Len maintenance (at maximum tolerated dose of 5 to 15 mg orally daily until progression) with dose modifications for toxicities. All patients were reviewed centrally for eligibility, response and progression. The primary objective was to compare 38-month PFS of the three arms. The events for PFS included progression, non-protocol anti-myeloma therapy, or death. Comparisons between treatment groups were based on pairwise log-rank tests stratified on disease risk, with significance levels adjusted for the 3 pairwise comparisons and for interim analyses. In calculating the cumulative incidence of progression, the events were progression or non-protocol anti-myeloma therapy, and death was a competing risk. Results: From June 2010 to November 2013, 758 pts (ACM, N=254; TAM, N=247; AM, N=257) aged 20-70 years (median 57y) were enrolled. Of those enrolled, 24% were classified as high risk. Non-compliance rates following the first autoHCT were 12%, 32% and 5% for ACM, TAM and AM, respectively. Median available follow up from randomization was 38 months. Follow-up is continuing through January 2017. 38-month estimated probabilities for PFS were 57% (95% CI: 50-63%), 56% (95% CI: 49-63%) and 52% (95% CI: 45-59%) for ACM, TAM and AM, respectively (ACM vs TAM p=0.75, ACM vs AM p=0.21, TAM vs AM p=0.37). Corresponding probabilities of OS were 86% (95% CI: 80-90%), 82% (95%CI: 76-87%) and 83% (95% CI: 78-88%). Median OS has not been reached. Cumulative incidences of disease progression at 38 months were 42% (95% CI: 36-48%), 42% (95% CI: 35-48%) and 47% (95% CI: 40-54%) for the ACM, TAM and AM arms, respectively. There were 39 cases of second primary malignancy (SPM) reported in 36 participants and the cumulative incidences for first SPM were 6.0% (95% CI: 3.4-9.6%), 5.9% (95% CI: 3.3-9.6%) and 4.0% (95% CI: 1.9-7.2%) for the ACM, TAM, and AM, respectively. Conclusions: The primary results of the largest randomized US transplant trial in MM demonstrated comparable PFS and OS. The addition of RVD consolidation or a second auto-HCT was not superior to a single auto HCT followed by Len maintenance in the upfront treatment of MM. A long term follow-up trial to track outcomes in these patients is ongoing.

Abstract Background. Current upfront treatment of light chain (AL) amyloidosis is often based on bortezomib in patients. However, data on the safety and efficacy of bortezomib in this setting mostly derive from uncontrolled, retrospective series, that are difficult to compare due to different proportion of patients with advanced disease. Here we report the analysis of a multicenter randomized phase III trial comparing MDex, a current standard of care, and MDex with the addition of bortezomib (BMDex) in newly-diagnosed AL amyloidosis that was performed in Europe and Australia (EMN-03 study, NCT01277016). Patients and Methods. Main eligibility criteria included measurable disease (M-protein >10 g/L or dFLC >50 mg/L), estimated glomerular filtration rate (eGFR) ³30 mL/min, and adequate liver function. Previously treated patients, those who had >30% bone marrow plasma cell or lytic bone lesions, NYHA class >II heart failure, grade 3 sensory or grade 1 painful peripheral neuropathy, or ECOG performance status >2 were excluded. In January 2013 the protocol was amended to include Mayo stage III patients, provided their NT-proBNP was <8500 ng/L (stage IIIa). Patients were randomized to receive either MDex (melphalan at 0.22 mg/kg and dexamethasone at 40 mg daily for 4 consecutive days every 28 days) or BMDex (bortezomib added at 1.3 mg/m2, on days 1, 4, 8, and 11 in cycles 1 and 2, and on days 1, 8, 15, and 22 in the following cycles). The primary endpoint was overall hematologic response at 3 months. Treatment was continued until completion of MDex cycle 9 or BMDex cycle 8, or achievement of CR or of at least partial response (PR) plus organ response after cycle 6, and was discontinued in case PR was not achieved by cycle 3. Enrollment is now completed (110 patients) with the last patient enrolled in February 2016 (database lock: July 25, 2016). Results. Patients' characteristics are reported in the Table. The proportion of patients experiencing at least 1 grade 3-4 severe adverse events (SAE) was similar in the MDex and BMDex arms (49% vs. 60%, P=0.11). The total number of reported adverse events per cycle was lower in the MDex group (10% vs 23%, P<0.01). Most common SAEs (MDex vs. BMDex) were cytopenia (4% vs. 7%, P=0.04), fluid retention (3% vs. 6%, P=0.02), and neuropathy (0 vs. 2%, P<0.01). One patient died within 3 months in the MDex arm and 3 in the BMDex group (P=0.28). Response was evaluated by intent to treat. Hematologic response rates after cycle 3 were 51% and 78% (P=0.001), with 28% and 53% complete response (CR) /very good partial response (VGPR) (P=0.003), in the MDex and BMDex arms, respectively. Overall hematologic response at the end of treatment, after a median of 5 cycles, was 56% and 81% (P=0.001), with 38% and 64% CR/VGPR in the MDex and BMDex arms, respectively (P=0.002). Cardiac response was reached in 8 of 33 evaluable patients treated with MDex (24%) and 10 of 26 (38%) who received BMDex (P=0.119). Renal response was attained in 17 of 35 patients (48%) in both arms. However, there was a higher proportion of cardiac progression in the MDex arm with borderline statistical significance (32% vs. 15%, P=0.054). After a median follow-up of living patients of 25 months, 26 patients (24%) died, 16 in the MDex arm and 10 in the BMDex arm with no significant difference in survival (Figure 1a). Achievement of hematologic and cardiac response at 3 months significantly improved survival (Figures 1b and 1c). Conclusion. This is the first prospective randomized trial of novel agents in AL amyloidosis. The criteria of hematologic and cardiac response are validated in the prospective setting for the first time. The primary endpoint, hematologic response at 3 months has been reached, showing more frequent and more profound hematologic responses with BMDex, preventing progression of cardiac dysfunction, with a modest increase in toxicity. This regimen can be proposed as a new standard of care in AL amyloidosis.
