Daratumumab, Cyclophosphamide, Bortezomib, Lenalidomide, Dexamethasone (Dara-CVRd), V-Augmented Autologous Stem Cell Transplant (V-ASCT) and Dara-Vrd Consolidation in Ultra-High Risk (UHiR) Newly Diagnosed Myeloma (NDMM) and Primary Plasma Cell Leukemia (pPCL) Compared with Myeloma XI/XI+ Trial Treatment for Uhir MM: The UK Optimum/Muknine Trial

Abstract Background: Outcomes for patients with ultra-high risk (UHiR) newly diagnosed multiple myeloma (NDMM) and patients with primary plasma cell leukemia (pPCL) remain unsatisfactory with current standard therapies. Traditional comparative trials randomising against a standard of care control arm are thus challenging for patients with UHiR NDMM or pPCL, and novel approaches to address their high unmet need are required. OPTIMUM/MUKnine (NCT03188172) is a 'digital comparator arm' trial for UHiR NDMM and pPCL patients with protocol defined outcome comparison against fully molecularly matched UHiR patients from the near-concurrent NCRI Myeloma XI/XI+ trial, the 'MyXI prior'. We report final analysis of the primary endpoint progression free survival (PFS) at 18 months for patients treated in OPTIMUM with Dara-CVRd induction, V-augmented ASCT and Dara-VRd consolidation, compared to the MyXI prior. Methods: Between Sep 2017 and Jul 2019, 472 patients from 39 UK hospitals with suspected NDMM or pPCL were screened. 107 patients with UHiR NDMM by central trial genetic (≥2 high risk lesions: t(4;14), t(14;16), t(14;20), gain(1q), del(1p), del(17p)) or gene expression SKY92 (SkylineDx) profiling, or with pPCL (circulating plasmablasts >20%) were identified and recruited to OPTIMUM. Patients received up to 6 cycles of Dara-CVRd induction, V-ASCT, followed by Dara-VRd consolidation 1 for 6 cycles (Cons1), Dara-VR consolidation 2 for 12 cycles and monthly Dara-R maintenance until progression. This is the final analysis of the primary trial endpoint progression-free survival (PFS) at 18 months comparing OPTIMUM with the MyXI prior of patients treated with CRd or carfilzomib-CRd (KCRd) induction, ASCT and R maintenance or observation, using a Bayesian framework. Secondary endpoints include PFS, OS, safety and quality of life. Results: At median follow-up of 27.1 months (95% CI 25.1-29.3), median PFS was not reached for OPTIMUM patients. PFS was superior at the pre-specified time point of 18 months for OPTIMUM patients with an estimate of 81.7% (95% CI: 74.2-89.1) versus 65.9% (95% CI: 57.3-74.4) for the MyXI prior (Figure 1). PFS at 18 months was consistently shorter for both CRd (64.5%; 95% CI: 53.8-75.3) and KCRd (68.3%; 95% CI: 54.0-82.5) treated patients compared with OPTIMUM. There was a 99.5% chance of superior PFS outcome with OPTIMUM therapy compared to the MyXI prior within the Bayesian framework; easily surpassing the 85% pre-specified threshold of sufficient evidence of activity. The difference between trial treatments increased over time: 6 month estimates were similar across all treatment arms with OPTIMUM 95.3% (95% CI: 91.3-99.3), MyXI KCRd 95.1% (95% CI: 88.5-100.0), MyXI CRd 93.5% (95% CI: 88.0-99.0), while 12 month estimates were similar for OPTIMUM with 87.5% (95% CI: 81.2-93.9) and MyXI KCRd 87.8% (77.8-97.8), but lower in CRd 81.7% (95% CI: 73.0-90.3). The majority (94%) of patients who started OPTIMUM Cons1 completed all 6 cycles of therapy. Most frequent grade 3/4 adverse events (AEs) during Cons1 included thrombocytopenia (27.9%), neutropenia (21%) and infection (19.8%), however, grade 4 events were rare (<5%) for all categories, consistent with previously presented data on induction. We previously reported high MRD-negativity rates of 61% at day +100 post V-ASCT for OPTIMUM, with a lower rate of 40% of patients showing both complete response (CR) and MRD-neg. With further follow-up, CR rate increased to 68.2% (95% CI: 58.5-76.9) at end of Cons1, including virtually all patients with MRD-neg finding post V-ASCT. Conclusions: OPTIMUM demonstrated a clear PFS benefit at 18 months for intensified Dara combination therapy pre- and post-ASCT for UHiR NDMM and pPCL over the MyXI prior. Improvement of comparative benefit over time suggests particular efficacy of Dara-VRd in maintaining responses post ASCT, a key challenge in UHiR MM. This is, to our knowledge, the first prospective digital comparator trial for MM; central screening of an all-comer population combined with robust, detailed molecular matching maintained reliability and limited biases. These results demonstrate a novel framework for accelerated comparative evidence generation for patients with high unmet clinical need. Figure 1 Figure 1.

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 Introduction Ixazomib is an orally available proteasome inhibitor, shown to be safe and efficacious in combination with lenalidomide and dexamethasone (IRd regimen) in patients with relapsed and refractory multiple myeloma (RRMM) with 1-3 prior lines, demonstrating a progression free survival (PFS) benefit which was similar across cytogenetic risk groups (Tourmaline-MM1 phase 3 trial). A European real world data analysis of an IRd named patient program (NPP) outcomes in Greece (n=35), UK (n=46) and Check republic (n=57) showed similar favorable outcomes (Terpos et al, Blood 2017 130:3087). We aimed to analyze outcomes of ixazomib combinations among a multi-site cohort in the Israeli Myeloma registry. Overall response rate (ORR) was classified according to IMWG criteria. Primary endpoint was PFS, secondary endpoints included ORR, overall survival (OS), safety and tolerability. Patients A total of 78 patients across 7 sites, who received at least one cycle of ixazomib combination between June 2013 and June 2018 for treatment of RRMM were retrospectively included. Median age was 68 (range: 38-90). Male/Female ratio was 42/36. ISS (rISS) I/II/II was 30%/42%/27% (25%/54%/15%). Patient received between 1 and 7 prior lines of therapy, 66% received ixazomib in 2nd line, 18% in 3rd line. Overall, 89% of patients had been exposed to PIs (bortezomib 86%) prior to IRd, 41% to IMiDs (thalidomide 28% lenalidomide 22% and pomalidomide 6%), and 35% had undergone autologous transplantation (ASCT). Induction treatment was mostly bortezomib based (85%), most frequently VCD (62%). FISH cytogenetics were available for 60 patients, 29 (48%) had high or intermediate risk aberrations (t(4:14) 12 pts, amp 1q21 12 pts, del17p 9 pts). Disease aggressiveness was classified by treating physician as indolent (rapid control to protect from target organ damage not required) vs aggressive (imminent target organ damage) in 63% vs 27%, respectively. 60 (77%) of the 78 patients received ixazomib via a named patient program, the rest via national or private healthcare provider. Results Median time of follow up from first ixazomib dose was 22 months (range: 1-39 months), and 54 months from diagnosis of myeloma. Treatment is ongoing in 44 (56%) patients with a median duration of 19 months (range: 1-29). Among patients who discontinued treatment, the median duration was 9 months (1-31). Ixazomib was combined with lenalidomide, pomalidomide, and daratumumab in 69%, 9% and 4%, respectively. Overall response rate was 88% - CR 10%, VGPR 36%, PR 42%. Progression free survival was 78% and 54% at 12 and 24 months, respectively (fig1a). A worse PFS was found with physician assessment of aggressive vs indolent disease (14.5 vs 25.9 months, p=0.001), and with post induction progression free period (PFS1) ≤ 24 months vs. >24 months (23.9 vs 31.5 months, p=0.038) (fig 1b); age >=65 trended towards a worse PFS (p=0.058). Poor cytogenetic risk, prior exposure to bortezomib, prior auto transplant, and number of prior lines of therapy did not affect PFS or ORR. OS from first ixazomib administration was 90% and 81% at 12 and 24 months, respectively; median OS was not reached (fig1a). Any (grade 3-4) toxicity considered by investigator as related to ixazomib was reported in 70% (18% grade 3-4), including neutropenia 14% (6%), anemia 19% (6%), thrombocytopenia 17% (5%), nausea and vomiting 17% (1%), DVT/PE 4% (1%), neutropenic infection 0 (4%), peripheral neuropathy 14% (3%), diarrhea 14% (3%), rash 10% (4%), pneumonia 5% (3%). There were no ixazomib related deaths. Dose reduction or discontinuation due to toxicity occurred in 28% and 12%, respectively. Conclusion Our data shows ixazomib-based combinations are efficacious and safe regimens for patients with RRMM, achieving ORR of 88%, at 2nd as well as later lines of therapy, regardless to cytogenetic risk. Over a median follow up of almost 2-years, 54% remained progression free at 24 months. An ixazomib based regimen may be particularly attractive for patients who remain progression free for more than 24 months after a bortezomib induction and for patients with a more indolent disease phenotype.

302 Background: In the phase III JAVELIN Renal 101 trial (NCT02684006), A + Ax demonstrated progression-free survival (PFS) and objective response rate (ORR) benefit across IMDC risk groups (favorable, intermediate, and poor) vs S in patients with previously untreated aRCC. Here we report efficacy of A + Ax vs S by number of IMDC risk factors (0, 1, 2, 3, and 4-6) and target tumor sites (1, 2, 3, and ≥4) at baseline from the second interim analysis of overall survival (OS). Methods: Patients were randomized 1:1 to receive A 10 mg/kg intravenously every 2 wk + Ax 5 mg orally twice daily or S 50 mg orally once daily for 4 wk (6-wk cycle). PFS and ORR per independent central review (RECIST 1.1) and OS were assessed. Results: At data cut-off (Jan 2019), median (m) follow-up for OS and PFS was 19.3 vs 19.2 mo and 16.8 vs 15.2 mo for the A + Ax vs S arm, respectively. The table shows OS, PFS, and ORR by number of IMDC risk factors and target tumor sites at baseline. A + Ax generally demonstrated efficacy benefit vs S across subgroups. Conclusions: With extended follow-up, A + Ax generally demonstrated efficacy benefit vs S across the number of IMDC risk factors and tumor sites at baseline in aRCC. OS was still immature; follow-up for the final analysis is ongoing. Clinical trial information: NCT02684006 . [Table: see text]

Univariate Analyses

Factors which might influence outcome in patients with meningioma are not well-understood. Previous studies have examined associations of laboratory blood values including hemoglobin levels with patient outcomes in cancer. We hypothesized those changes in CBC before tumor resection can be used as one of the prognostic factors for tumor recurrence/progression in meningioma. To address this, we gathered the clinical and pre-operative CBC results for final analysis from 226 patients (64 males and 162 females) who underwent craniotomy for primary meningioma (grades: 157 WHO GI, 59 GII, 10 GIII) at our institution between 2001 and 2015.Individual parameters were analyzed for correlation with progression-free survival. The median recurrence free survival (RFS) was not reached and follow-up ranged 0.3-14 years. Fifty-six patients (25%) had anemia and 30% of the patients showed leukocytosis using standard cut-offs. On univariate analyses, low hemoglobin (Hb) level, as well as high leukocytes (Lkc), neutrophil (Neutro) and monocyte counts correlated with worse RFS. As expected, tumor grade was correlated with RFS. Low Hb level, high Lkc and Neutro counts were all significantly associated with RFS after adjusting for grade. Strikingly, 32% of patients with pre-operative anemia experienced a recurrence at 5 years, compared with only 11% of non-anemic patients. Conclusion: In this exploratory study, we find that pre-operative CBC data, which is readily available, may contain prognostic information relevant to subsequent risk of recurrence or progression in meningioma. While the biological mechanism for these associations is not clear, they represent hypotheses for further investigation.

Purpose: Hodgkin's lymphoma (HL) is a highly curable disease even in advanced-stage, with >90% of long-term survivors. Currently, the standard of care is ABVD (doxorubicin, etoposide, vinblastine and dacarbazine), as it is less toxic and as effective as other more intensive chemotherapy regimens. Alternatively, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone) has been proposed as front-line intensified regimen with a better initial disease control and prolonged time to relapse when compared to ABVD. However, this advantage is associated with higher rates of severe hematologic toxicity, treatment-related deaths, secondary neoplasms and infertility. To date, the debate regarding which regimen should be preferred as first line for advanced-stage HL is still ongoing. To shed some light on this open question we compared efficacy and safety of both regimens in clinical practice. Patients and Methods: From October 2009 to October 2018, patients with HL stage III-IV treated with either ABVD or BEACOPP escalated (BEACOPPesc) were retrospectively assessed in 7 European cancer centers. Results: A total of 372 consecutive patients were included in the study. One-hundred and ten patients were treated with BEACOPPesc and 262 with ABVD. The baseline characteristics of the two groups did not differ significantly, except for a higher rate of high-risk patients in the BEACOPPesc group in contrast to the ABVD one (47% vs 18%; p= 0.003). Complete response rate (CR) assessed by PET imaging at the end of the second cycle was 67% and 78% for the ABVD and BEACOPPesc group (p= 0.003), respectively. Thirteen patients of the ABVD group achieved stable disease (SD) and 6 had a progression disease (PD). On the other hand, 4 of the patients in the BEACOPPesc group progressed, another 2 interrupted therapy because life-threatening toxicity. At the end of the therapy, CR was 76% in the ABVD group and 85% in the BEACOPPesc group (p= 0.01). A total of 20% patients in the ABVD group and 14% patients in the BEACOPPesc group received consolidation radiotherapy on the mediastinal mass at the dose of 30Gy. After radiotherapy, the number of patients with CR increased to 79% and 87% in the two groups (p= 0.041), respectively. Thirty-nine patients (35%) in the BEACOPPesc group required dose reduction of chemotherapy due to toxicity compared to 12 patients (5%; p= <0.001) in the ABVD group. Overall, the rate of severe toxicities was higher in the BEACOPPesc group in comparison with the ABVD cohort. In particular, there was a significant increased frequency of acute grade 3-4 hematologic adverse events (neutropenia 61% vs 24%; anemia 29% vs 4%; thrombocytopenia 29% vs 3%), febrile neutropenia (29% vs 3%), severe infections (18% vs 3%). Myeloid growth factors were administered to 85% and 59% of patients in the BEACOPPesc group compared to the ABVD group. Blood transfusions were required in 51% and 6% of patients in the BEACOPPesc group compared to the ABVD cohort. Progression during or shortly after treatment occurred in 5 patients in the BEACOPPesc group (4%) and in 16 patients in the ABVD group (6%; p= 0.62). Among the 96 patients who achieved a CR after BEACOPPesc and radiotherapy, 8 relapsed (8%), compared to 29 of 208 patients in the ABVD group (14%; p= 0.04). At a median follow-up period of 5 years, no statistical difference in progression free survival (PFS; p=0.11) and event-free survival (EFS; p=0.22) was observed between the BEACOPPesc and ABVD cohorts. Similarly, overall survival (OS) did not differ between the two groups (p=0.14). The baseline international prognostic score (IPS <3 vs ≥ 3) significantly influenced the EFS with an advantage for the high-risk group treated with BEACOPPesc (Figure 1A; p=0.03), but not the PFS (Figure 1B; p=0.06) and OS (Figure 1C; p=0.14). During the follow-up period, in the BEACOPPesc group one patient developed myelodysplasia and one acute leukemia. Second solid tumors developed in one patient in the ABVD group (lung cancer) and one in BEACOPPesc group (breast cancer). Conclusion: We confirm that the ABVD regimen is an effective and less toxic therapeutic option for advanced-stage HL. Although BEACOPP results in better initial tumor control especially in high-risk patients, the long-term outcome remains similar between the two regimens.

Abstract Abstract 2854 Alemtuzumab (A) proved to be efficacious in CLL patients (pts) with very poor prognosis, either due to fludarabine (F) refractoriness or due to unfavorable cytogenetics (17p-). However, rate and duration of remissions still remain unsatisfactory. Therefore, the French and German CLL study groups jointly embarked on this trial, trying to achieve higher overall response rates (ORR) by adding high-dose dexamethasone (D) to A and, simultaneously, investigating the consolidation effect of prolonged A maintenance or allogeneic stem-cell transplantation (allo-SCT), respectively. Induction treatment consisted of subcutaneous A 30 mg weekly × 3 for 28 days, combined with oral D 40 mg on days 1–4 and 15–18, and prophylactic pegfilgrastim 6 mg on days 1 and 15. Depending on the remission status, pts were treated for up to 12 weeks. If CR was documented at 4 or 8 weeks, or at least SD was achieved at 12 weeks, consolidation was scheduled with either allo-SCT or A maintenance with 30 mg every 14 days for up to 2 years (y), at the discretion of pt and physician. Between January 2008 and July 2011, 124 pts were recruited at 26 centers, 120 of whom were eligible. Pts were generally subdivided into three cohorts: 55 pts were refractory (i.e. no response or relapse within 6 months) to regimens containing F or a similar drug (i.e. pentostatin, cladribine, bendamustine). Non-refractory pts all exhibited 17p- and had either untreated (n=39) or relapsed CLL (n = 26) requiring therapy. The median age was high with 66/64/66 y in 17p- 1st line, 17p- relapse, and F-refractory pts, respectively. The three cohorts had 46/54/75% Binet C disease, 41/35/27% B symptoms, 38/42/53% reduced performance status (ECOG 1/2), median thymidine kinase levels of 35/49/24 U/L, median ß2MG levels of 3.8/5.5/4.6 mg/L, and IGHV was unmutated in 89/96/87%. In the F-refractory group, 53% exhibited 17p deletion and 22% had 11q deletion. Pretreated patients had received a median of 3 (F-refractory) or 2 prior lines (17p- relapse). 5 pts had previously undergone autologous and 1 pt allo-SCT. Treatment and efficacy data are currently available for 87 pts who completed induction therapy :17p- 1st-line (n=30), 17p- relapse (n=17), and F-refractory (n=40). Of these, 80/53/55% received the full induction of 12 weeks. ORR (best observed status) was generally high with 97/76/70%. CR was achieved in 20/0/5%. After a median follow-up of 11.8 months (mo), median progression-free survival (PFS) was 16.9/10.4/8.4 mo. Deaths are recorded in 13/27/36% of pts, with median overall survival (OS) not yet reached (>24 mo) in the 17p- 1st line group, and 15/12 mo in 17p- relapse/F-refractory pts. Consolidation treatment was performed as maintenance A (median duration 32 weeks, range 2 – 89) in 34%, and allo-SCT in 30%, with a median age of 66 and 61 y in these subgroups. The main reasons for going off-study without consolidation were death due to infection (14%, n=11, of these 6 without response, and 10 in the F-refractory cohort), CLL progression (12%), and other toxicity (5%). Among the 28 pts not receiving consolidation, there were 19 (68%) deaths, 15 of them in the F-refractory cohort. When comparing A maintenance and allo-SCT for consolidation, there were 9 (35%) and 7 (30%) PD events, respectively and there was so far no significant difference in PFS (median 17 mo in both groups) or OS. During induction, grade 3/4 hematotoxicity consisted of anemia in 28%, neutropenia in 47%, and thrombopenia in 44%. Grade 3/4 non-CMV infection occurred in 29% of 17p- 1st-line, 15% of 17p- relapsed, and 56% of F-refractory pts. CMV reactivation was observed in 54/25/40%, without severe sequelae recorded. During A maintenance, grade 3/4 toxicity consisted of neutropenia in 39% pts and thrombopenia in 4% pts with 6 SAEs (ITP, diarrhea, infection, erythema, tachycardia, and thrombosis). Conclusions: The combination of A and D shows high response rates in ultra high-risk CLL, with promising preliminary findings for PFS and OS, despite the high median age of the pts. The results compare favorably to ORR/CR of 68%/5%, and median PFS of 11.3 mo in the 17p- subgroup of the CLL8 study treated with FCR, consisting of younger pts (median 61 y). In F-refractory CLL however, when compared to the preceding CLL2H study with single agent A, the improved initial response by adding dexamethasone does not seem to translate into improved long-term results. More mature follow-up is needed, especially with respect to the impact of allo-SCT.

Abstract Introduction The activity of the drug efflux transporter protein MDR1 reduces the intracellular concentration of nilotinib and thereby impairs its efficacy. Nilotinib has been shown to be efficacious in imatinib-resistant patients. In the face of competing second-generation tyrosine-kinase inhibitors (TKI), early identification of favorable responders is crucially important. We have reported the unexpected positive prognostic impact of high MDR1 gene expression at time of imatinib resistance for subsequent 2nd line nilotinib treatment. Here, we present (i) a 48-month follow-up of our clinical data and (ii) additional functional analyses studied in an established in vitro, transposon-based vector system with stable siRNA mediated knockdown of MDR1. Aim We sought to assess (i) whether high MDR1 expression remains associated with improved cumulative rates of major molecular remission (MMR), complete cytogenetic remission (CCyR) and patients’ outcome (progression-free survival, PFS) after 48 months and (ii) the impact of MDR1 expression on nilotinib in vitro sensitivity. Methods (i) We analyzed 83 patients resistant to imatinib frontline treatment in chronic phase CML treated with nilotinib 400 mg bid within the CAMN107A2101 trial. MDR1 and BCR-ABL mRNA expression levels were determined by qRT-PCR using LightCycler™ technology, normalized against beta-glucuronidase (GUS) and standardized according to the international scale (IS). Log-rank tests were performed to compare PFS and the cumulative incidences (CI) of MMR and CCyR at 48 months. (ii) MDR1high overexpressing (K562-DoxH1) and MDR1low knockdown (K562-DoxMM) cell lines were used for in vitro testing (Rumpold et al., Exp Hematol 2005). Results (i) (a) At 24 and 48 months, patients with MDR1/GUS ratios ≥2.0 attained MMR in 39% and 41%, CCyR in 58% (at both time points), and PFS rates of 75% and 67%, whereas patients with initial MDR1/GUS ratios <2.0 had significantly worse response and PFS rates, i.e. MMR in 13% and 16% (p=0.014), CCyR in 35% and 39% (p=0.044), and PFS of 50% and 46% (p=0.032). (b) BCR-ABL tumor burden prior to nilotinib revealed a significant impact on molecular response rates. BCR-ABLIS <28% separated best concerning cumulative incidences of MMR by 24 and 48 months (41% vs 21% and 48% vs 21%, p=0.009). (c) Nilotinib in vitro sensitivity of BCR-ABL kinase domain mutations at time of imatinib resistance was associated with improved PFS under nilotinib therapy: patients without any mutation showed PFS rates of 71% and 63% at 24 and 48 months, whereas those with either sensitive mutations, intermediately sensitive mutations or mutations with unknown IC50attained PFS rates of 67% and 61%; patients with mutations resistant to nilotinib achieved PFS rates of 23% at both time points (p=0.01). (ii) Even though MDR1high K562 cells are less sensitive than MDR1low expressing cells, nilotinib (applying doses from 0.01 µM up to 0.5 µM) was still able to significantly impede proliferation of both MDR1high and MDR1low, whereas imatinib-mediated growth inhibition was only seen in MDR1low, but not in MDR1highcells. Conclusion (i) At the time of imatinib-resistance, a high MDR1 gene expression predicts favorable MMR, CCyR, and PFS on consecutive 2nd line nilotinib treatment. As shown earlier, single nucleotide polymorphisms (SNPs) within MDR1 (1236CT/TT and 2677GT/TT) were significantly associated with higher MDR1 expression. (Agrawal et al., ASH 2010) (ii) Our functional data support our clinical observation that nilotinib remains efficacious in MDR1 overexpressing cells, whereas even dose-escalated imatinib does not reverse resistance. High MDR1 gene expression might select patients whose mode of resistance is essentially determined by increased efflux activity of MDR1 and not by other pathways of resistance that cannot be overcome by nilotinib. Altogether, our data might be used for the clinical risk stratification in case of imatinib resistance before switching to nilotinib and are undergoing prospective validation within the ENEST1st study.

7528 Background: Previously in the COMPLEMENT 1 study, treatment with OFA and CHL in pts with untreated CLL had shown a significant improvement in the progression-free survival (PFS) compared with CHL alone, and was well tolerated. Here, we report the final overall survival (OS) analysis of the 5-year (y) follow-up, updated investigator-assessed PFS and safety from the study. Methods: Untreated pts, not fit for fludarabine-based therapy (due to advanced age or co-morbidities) were randomized 1:1 to OFA+CHL or CHL alone. Pts in OFA+CHL arm received OFA (Cycle 1: 300 mg day (d) 1, 1000 mg d8; subsequent cycles: 1000 mg d1) in addition to CHL (10 mg/m2, d1-7) for 3 to 12 cycles of 28 d each. Pts in CHL arm received CHL only. Results: Overall, 447 pts were randomized to OFA+CHL (n = 221) or CHL (n = 226); 168 (76%) and 164 (73%) pts completed the scheduled treatments, respectively. Baseline characteristics were similar in both arms. The investigator-assessed median PFS was 23.4 months (mos) in the OFA+CHL arm and 14.7 mos in the CHL arm (HR: 0.61 [95% CI 0.49, 0.76], p < 0.001). Median OS could not be estimated for the OFA+CHL arm and was 84.7 mos for the CHL arm (HR: 0.88 [95% CI 0.65, 1.17], p = 0.363). Estimated OS rate (95% CI) at 5 y was 68.5% (61.5%, 74.5%) in the OFA+CHL arm, and 65.7% (58.6%, 71.9%) in the CHL arm. Post-treatment anti-cancer therapy after discontinuation was received by a greater proportion of pts in the CHL (66%) vs. OFA+CHL (56%), and started earlier in the CHL arm (486 d) vs. OFA+CHL (743 d) arm. Overall, 84 (39%) pts in the OFA+CHL, and 99 (44%) pts in the CHL arms died during the study with 5 on-treatment deaths in each group. Grade ≥3 adverse events were seen in 64% and 48% of pts in the OFA+CHL vs. CHL arms, respectively, most common being (≥5% in either arm) neutropenia (26% vs. 15%), thrombocytopenia (5% vs. 10%), pneumonia (9% vs. 5%), and anemia (5% vs. 5%). Conclusions: This 5-y survival follow-up analysis supported the results from primary analysis with an estimated 12% (not significant) and 39% risk reduction in OS and PFS, respectively, in the OFA+CHL arm compared with the CHL arm. No new safety concerns were observed in the OFA+CHL arm. Clinical trial information: NCT00748189.

Purpose The aim of the F2 study was to verify whether a prospective collection of data would enable the development of a more accurate prognostic index for follicular lymphoma (FL) by using parameters which could not be retrospectively studied before, and by choosing progression-free survival (PFS) as principal end point. Patients and Methods Between January 2003 and May 2005, 1,093 patients with a newly diagnosed FL were registered and 942 individuals receiving antilymphoma therapy were selected as the study population. The variables we used for score definition were selected by means of bootstrap resampling procedures on 832 patients with complete data. Procedures to select the model that would minimize errors were also performed. Results After a median follow-up of 38 months, 261 events for PFS evaluation were recorded. β2-microglobulin higher than the upper limit of normal, longest diameter of the largest involved node longer than 6 cm, bone marrow involvement, hemoglobin level lower than 12 g/dL, and age older than 60 years were factors independently predictive for PFS. Using these variables, a prognostic model was devised to identify three groups at different levels of risk. The 3-year PFS rate was 91%, 69%, and 51% for patients at low, intermediate, and high risk, respectively (log-rank = 64.6; P < .00001). The 3-year survival rate was 99%, 96%, and 84% for patients at low, intermediate, and high risk, respectively (P < .0001). Conclusion Follicular Lymphoma International Prognostic Index 2 is a simple prognostic index based on easily available clinical data and may represent a promising new tool for the identification of patients with FL at different risk in the era of immunochemotherapy.

Abstract Background: Novel agents capable of inducing deeper responses dramatically improve the prognosis of patients with multiple myeloma (MM). Innovative technologies such as multiparameter flow cytometry (MFC) and next-generation sequencing (NGS) are utilized to assess minimal residual disease (MRD) for further stratification of patients who achieve a complete response (CR). EuroFlow-next-generation flow (EuroFlow-NGF) is one of the gold standard MFC methods. Recently, both NGF and NGS have been used in many clinical trials to assess MRD levels associated with progression-free survival (PFS) and overall survival (OS). The present study prospectively assessed MRD levels by both NGF and NGS to elucidate the prognostic impact of both methods and clarify their characteristics in MM patients in an autologous stem cell transplantation (ASCT) setting. Methods: We prospectively assessed the response in Japanese patients with newly diagnosed MM who underwent ASCT and lenalidomide-based maintenance therapy at multiple Japanese medical centers between September 2016 and July 2021. The diagnosis of MM and patients' responses to therapy were assessed using the IMWG criteria. Only patients with CR or stringent CR on days 100-365 post-ASCT were included, and bone marrow (BM) samples were obtained to assess MRD. Four milliliters of BM was divided equally. Cells derived from 2 mL BM were analyzed by the NGF method (Flores-Montero et al., Leukemia 2017) at Kanazawa University, and DNA extracted from the remaining 2 mL BM cells was processed by Adaptive Biotechnologies' standardized NGS-MRD assay (Seattle, WA) (Ching et al., BMC Cancer 2020) to assess MRD levels. MRD levels in BM were also monitored at 1-year (± 20 days) and 2-year (± 20 days) post-ASCT. The prognostic value of MRD levels in BM was assessed, and their correlation between NGF and NGS was compared at a cut-off value of 1×10 -5. Sustained MRD negativity was defined as the maintenance of MRD negativity in the BM for more than 6 months. BM cells were analyzed for high-risk cytogenetics (del(17p), t(4;14), and t(14;16)) by FISH. Results: A total of 60 patients (male = 29, female = 31) underwent bortezomib-based induction therapy, ASCT conditioned with high-dose melphalan, and lenalidomide-based maintenance. The median age was 62 years at the ASCT (range 36-71; ISS 1 [n = 13], 2 [n = 24], and 3 [n = 23]). Thirty-three percent of patients showed high-risk chromosomal abnormalities (del17p (n=11), t(4;14) (n=10), t(14;16) (n=2)), 3 patients had double hit diseases, and five patients had extramedullary diseases. With a median follow-up of 3 years, the 3-year progression-free survival (PFS) and 3-year overall survival (OS) rates were 69.2% and 94.2%, respectively. In total, 148 samples were analyzed using NGF and 138 were analyzed using NGS. The rates of MRD negativity at least once using NGF and NGS were 80% and 61%, respectively. The patients who achieved at least one MRD negativity exhibited significantly better 3-year PFS (82.9% by NGF; 84.8% by NGS) than those who did not (P < 0.0001, 0% by NGF; P = 0.005, 49.1% by NGS). Patients who sustained MRD negativity for more than 6 months also showed significantly better 3-year PFS (96.7% by NGF; 92.3% by NGS) compared with those without sustained MRD negativity (Figure; P < 0.0001, 37.1% by NGF; P < 0.01, 50.9% by NGS). The MRD levels between the NGF and NGS methods were significantly correlated with each other (r = 0.9295, P < 0.0001). Among the 17 patients who developed PD after ASCT, seven cases showed discrepancies in the MRD results and two cases in which one case was MRD-positive and the other was MRD-negative by both methods progressed with extramedullary diseases. Five of the seven cases were MRD-positive by NGS and MRD-negative by NGF. Conclusions: In this prospective comparison study of MRD assessment in BM cells using EuroFlow-NGF and NGS approaches, MRD levels highly correlated with each other, and MRD negativity and sustained MRD negativity were significantly associated with prolonged PFS. Multiple MRD assessments by NGF or NGS are essential for predicting durable remission and prolonged clinical outcomes. Figure 1 Figure 1.
