Description: Background: Daratumumab is a human IgGκ monoclonal antibody targeting CD38 with a direct on-tumor and immunomodulatory mechanism of action. The intravenous (IV) formulation of daratumumab is approved in many countries for use as monotherapy in relapsed/refractory multiple myeloma (RRMM), and in combination with standard-of-care regimens in RRMM and patients with NDMM who are transplant ineligible. A subcutaneous (SC) formulation of daratumumab is currently under investigation in several ongoing studies. In the phase 3 COLUMBA study, daratumumab SC was shown to be non-inferior to daratumumab IV, demonstrating similar efficacy and pharmacokinetics, with a significantly decreased rate of infusion-related reactions and reduced administration time. The randomized phase 2 LYNX (MMY2065) study will evaluate the efficacy and safety of retreatment with subcutaneous daratumumab in patients with RRMM who were previously exposed to daratumumab IV therapy. Study Design and Methods: In this ongoing, multicenter, open-label, randomized phase 2 study, approximately 230 patients with prior exposure to daratumumab will be randomized 1:1 to receive daratumumab plus carfilzomib and dexamethasone (D-Kd) or carfilzomib and dexamethasone (Kd) alone. Patients must have received 1 to 2 prior lines of therapy (at least one of which included daratumumab IV) with the daratumumab-based therapy completed ≥3 months prior to randomization. Eligible patients must have achieved a partial response or better (as defined by International Myeloma Working Group [IMWG] criteria) to daratumumab-based therapy, with a duration of response of ≥4 months. Patients must not have discontinued daratumumab due to a daratumumab-related adverse event or received prior treatment with carfilzomib. All patients will receive 20 mg/m2 carfilzomib IV on Day 1 of Cycle 1, escalated to 70 mg/m2 on Days 8 and 15; carfilzomib 70 mg/m2 will be administered on Days 1, 8, and 15 of each 28-day cycle thereafter. Dexamethasone 40 mg will be administered (IV or PO) QW for Cycles 1-9 and then on Days 1, 8, and 15 from Cycle 10 onwards. Patients in the D-Kd group will also receive daratumumab SC (1,800 mg co-formulated with recombinant human hyaluronidase PH20 [rHuPH20; 2,000 U/mL; ENHANZE® drug delivery technology, Halozyme, Inc.]) QW in Cycles 1-2, Q2W in Cycles 3-6, and Q4W thereafter. The primary endpoint is the rate of patients achieving a very good partial response or better. Secondary endpoints include overall response rate, rate of patients achieving complete response or better, progression-free survival, overall survival, overall MRD-negativity rate, time to next treatment, pharmacokinetics, and safety. The ClinicalTrials.gov identifier is NCT03871829.

Description: This multicenter, first-in-human study evaluated the safety, tolerability, and pharmacokinetic and pharmacodynamic properties of the anti-CS1 monoclonal antibody elotuzumab. A standard 3 + 3 design was used to determine maximum tolerated dose; dose-limiting toxicities were assessed during cycle 1. Thirty-five patients with relapsed/refractory multiple myeloma were treated with intravenous elotuzumab at doses ranging from 0.5 to 20 mg/kg every 2 weeks. Patients who achieved at least stable disease after 4 treatments could receive another 4 treatments. No maximum tolerated dose was identified up to the maximum planned dose of 20 mg/kg. The most common adverse events, regardless of attribution, were cough, headache, back pain, fever, and chills. Adverse events were generally mild to moderate in severity, and adverse events attributed to study medication were primarily infusion-related. Plasma elotuzumab levels and terminal half-life increased with dose whereas clearance decreased, suggesting target-mediated clearance. CS1 on bone marrow–derived plasma cells was reliably saturated (≥ 95%) at the 10-mg/kg and 20-mg/kg dose levels. Using the European Group for Bone and Marrow Transplantation myeloma response criteria, 9 patients (26.5%) had stable disease. In summary, elotuzumab was generally well tolerated in this population, justifying further exploration of this agent in combination regimens.

Description: Abstract 3877 Poster Board III-813 Background Renal impairment affects 20% of newly diagnosed MM pts and over 50% during the course of their disease. Renal impairment confers shorter survival due to high tumor load and the difficulty in delivering adequate doses of active drugs, such as alkylating agents and immunomodulatory drugs (IMiDs) due to enhanced side effects (Kyle, Mayo Clin 2003). Pts with renal insufficiency have been traditionally excluded from clinical trials. Carfilzomib (CFZ) is a novel peptide epoxyketone proteasome inhibitor designed to have a high level of selectivity for the proteasome. In previous Phase 2 studies, CFZ has demonstrated single agent activity in heavily pretreated MM pts including those with mild renal insufficiency. The primary objective of this study was to evaluate the tolerability and pharmacokinetic properties of CFZ in MM pts with renal insufficiency, including those on dialysis. Methods In this multicenter study, MM pts who had relapsed after at least two prior therapies were enrolled into 4 cohorts based on renal impairment: normal (CrCl 〉 80mL/min), mild (CrCl 50–80 mL/min), moderate (CrCl 30–49 mL/min), and severe (CrCl 〈 30 mL/min) including dialysis pts. The primary and secondary objectives of the study included pharmacokinetics (PK), safety, pharmacodynamics (PDn; proteasome inhibition in blood) and efficacy endpoints: ORR (overall response rate, ≥ PR) CBR (clinical benefit response, ≥ MR), duration of response (DOR) and time to progression (TTP). Pts received CFZ at a dose of 15 mg/m2 IV on day (D) 1, 2, 8, 9, 15 and 16 every 28 d for cycle (C) 1, with dose escalation to 20 mg/m2 in C2 and 27 mg/m2 in C3 and thereafter if tolerated. Pts received 40 mg of dexamethasone (Dex) in cycle 3 if they had less than a partial response (PR). Pts were followed for toxicity and efficacy over the course of the study. EKG changes from baseline including QT/QTc effects were assessed in C1 and C2. PK was measured on C1 D1,15 and C2 D15 and PDn was measured on C1 D1,2,8 and C2 D1. Results Nineteen pts received at least 1 dose of CFZ and were evaluable for safety; 18 pts completed at least 1 C of CFZ and were evaluable for response and PK/PDn. All pts had refractory MM and 42% had progressed during their last therapy. The median number of prior therapies was 5 (range 2–10). All pts had received bortezomib and 26% were refractory; all pts received at lease one IMiD (90% thalidomide and 85% lenalidomide). Seventy percent had prior stem cell transplant. To date, pts have received a median of 3 cycles (range 1–7+) of CFZ; 9 pts have completed ≥ 6 cycles. The most common adverse events were fatigue, anemia, back pain and fever. There was no appreciable difference in the safety profile between the 4 cohorts either in frequency of events or in CTC-AE grade. Two deaths from disease progression with 1 complicated by a parainfluenza upper respiratory tract infection occurred while on study. No treatment emergent QT/QTc prolongations were observed during C1 and C2 in any group. Sixteen pts had grade 1 or 2 peripheral neuropathy at study entry and no cases of newly emergent or exacerbations occurred on study. Two pts discontinued drug due to worsening renal failure, one in the mild and one in the moderate cohort; both were related to disease progression. In all cohorts, CFZ was cleared with a t½ of 30–60 minutes and reached undetectable levels in plasma within 3 hours. There was no accumulation of CFZ after two cycles. Proteasome inhibition measured 1 hr post-dose in whole blood and PBMC ranged from 75–89% at doses of 15–20 mg/m2. PK and PDn were similar between the cohorts of pts with varying degrees of renal impairment. The ORR was 16.6% and CBR was 33.3%. Two BTZ-refractory pts achieved PR. An additional 38.9% had stable disease across all groups despite entering the study with progressive disease. Seven of 18 pts received Dex in ≥ C3 with 2 exhibiting an upgraded response (1 PR and 1 MR). Conclusions CFZ can be administered to MM pts with substantial renal dysfunction and does not require dose adjustment. CFZ toxicities in this study were manageable and importantly, exacerbation of pre-existing PN or myelosuppression was not observed in these renally impaired MM patients. Responses in relapsed and refractory MM pts with renal insufficiency are encouraging. Further evaluation of CFZ in renally impaired patients is ongoing, including in patients receiving hemodialysis.

Description: Background Multiple groups of pts, including elderly/frail pts and those with comorbidities, are typically under-represented in randomized controlled trials (RCTs). A recent study found an average of 16 eligibility criteria per cancer trial, 60% of which were related to comorbidity or performance status (PS; Unger, JNCI 2014). Phase 3 RCTs in MM have similar extensive eligibility criteria, resulting in populations that are not reflective of RW MM pts. Data from CONNECT-MM (Shah, CLML, 2017) and CoMMpass (Fiala, IMW 2017) suggest that 22-40% of RW pts are ineligible for MM RCTs, and an analysis of US RW relapsed/refractory MM (RRMM) pts showed that only 25-47% of pts would have been eligible for the phase 3 ASPIRE, TOURMALINE-MM1, ELOQUENT-2, and POLLUX studies, based on their differing eligibility criteria (Chari, EHA 2018). Further, data from CONNECT MM show that clinical trial ineligibility is associated with poorer long-term outcome (Shah, CLML, 2017). Thus, it is important to characterize RW MM pts and understand the discrepancies vs RCT populations. INSIGHT MM (NCT02761187) is the largest prospective, observational study in MM to date, following ~4,200 pts from 15 countries. Here we analyze RCT eligibility in INSIGHT MM pts, with a focus on the treatment of frail MM pts in the real world. Methods INSIGHT MM is following newly diagnosed (≤3 mos since treatment initiation) MM (NDMM) and RRMM (≤3 prior lines) pts. Demographics and disease characteristics, including medical history, comorbidities, PS, and frailty status (per IMWG Frailty Index criteria, Palumbo, JCO 2015), are collected using electronic case report forms at study baseline visit. For this analysis, pt data were reviewed vs 20 standard RCT eligibility criteria, using a conservative approach of classifying 'not available' data as 'eligible'; laboratory/PS and medical history exclusion criteria are summarized in the Table. Presence of hypertension was reviewed but omitted, as INSIGHT MM only collected data on 'hypertension requiring treatment' vs the standard RCT exclusion criterion of 'uncontrolled hypertension'. Results Data from 3,201 pts (1,761 NDMM, 1,440 RRMM) were analyzed. The proportions of pts who would be ineligible for RCTs based on each individual parameter, and the overall rate of ineligible pts, are shown in the Table. Overall, 39.2% of pts would have been ineligible for RCTs based on not meeting at least one of the 20 standard eligibility criteria included in this analysis, including 38.8% of NDMM and 39.7% of RRMM pts. The most common criteria excluding pts overall were another prior malignancy (7.5%), CrCl ≤30 mL/min (6.4%), cardiac arrhythmias (5.4%), platelets ≤75,000/mm3 (5.1%), and hemoglobin

Description: Background Ixazomib, the first oral proteasome inhibitor, has been approved for 〉3 years in 〉70 countries, for the treatment of RRMM pts who have received ≥1 prior therapy, on the basis of the TOURMALINE-MM1 study, which reported an overall response rate (ORR) of 78% and median progression free survival (PFS) of 20.6 mos. Although outcomes and tolerability in routine clinical practice often differ from data reported in clinical trials, growing evidence suggest that outcomes in patients treated with ixazomib-based regimens are comparable to those in the Phase 3 TOURMALINE-MM1 trial. We report on an expanded pooled analysis with longer follow-up of IRd therapy from the INSIGHT MM study (NCT02761187) and the Czech Registry of Monoclonal Gammopathies (RMG) to evaluate the effectiveness of IRd in RRMM pts in routine clinical practice. Methods INSIGHT MM is a large, prospective, observational study which has enrolled over 4,200 adult pts with MM from Europe (plus Israel, EUR), the US, Asia, and Latin America, with a planned follow-up of ≥5 years. The RMG comprises clinical data for 〉6,000 MM pts enrolled at 19 Czech and 4 Slovak centers. Eligible pts had 1-3 (INSIGHT) or ≥1 prior therapy (RMG) including an IR-based regimen. Individual pt level data on demographics, disease characteristics, treatment history, effectiveness, and safety from INSIGHT and RMG were integrated and analyzed. Best response or time to first response and PFS were determined as per investigator assessment, using IMWG criteria. PFS, duration of treatment (DOT), and overall survival (OS) were estimated using Kaplan Meier (KM) methodology, applying an exclusion criterion to account for immortal time bias (INSIGHT only). Results At data cutoff of 22 Nov 2018, 217 pts (83 in INSIGHT and 134 in RMG) from 11 countries had been included: 191 (88%) from EUR, 17 (8%) from the US, and 9 (4%) from Taiwan; 89% of pts were treated in an academic facility. At diagnosis, 32% of pts had ISS Stage III disease, 78% had bone lesions, 46% had anemia, and 12% had elevated creatinine. At study start, median age was 67 years with 12% 〉75 years; 58%/14% of pts had ECOG performance status 1/2. The distribution of immunoglobulin (Ig) heavy and light chain MM was as expected; 69% of pts had IgG MM. Overall, 21% of pts had extramedullary disease. Prior therapies included: bortezomib (90%), stem cell transplant (60%), thalidomide (47%), lenalidomide (26%), carfilzomib (8%), daratumumab (6%), and pomalidomide (2%). Median time from diagnosis to start of IRd therapy was 42.1 mos; 43%/35%/22% of pts received IRd at 2nd/3rd/≥4th line. The most common reasons for starting IRd were relapse/progression (87%) and insufficient response (10%). The most common CRAB criteria present were bone lesions (48%) and anemia (18%). Median duration of follow-up was 12.6 mos in all pts. At data cutoff, 117 (54%) pts had discontinued IRd; median DOT was 11.9 (95% CI: 9.4-15.2) mos; at 12 mos, 49% (41.3-56.2) of pts were still on treatment (KM estimates). Data on best response to therapy were available for 152 pts. The ORR was 74%, with 36% ≥VGPR; ORR with IRd at 2nd/3rd/ ≥4th-line therapy was 82%/71%/59%, including 43%/37%/17% ≥VGPR. Median time to first response was 1.2 mos (RMG); median time to best response was 3.7 mos (INSIGHT). Median PFS was 21.6 (95% CI: 13.6-26.7) mos across all lines. PFS rate at 12 mos was 62%, and 86 (40%) pts had progressed at data cutoff. Median time to next therapy (TTNT) was 31.5 (95% CI: 24.5-35.9) mos, with a 12-month rate of 74% across all lines. Overall, 60 (28%) pts received subsequent therapies including daratumumab (22%), pomalidomide (22%), bortezomib (20%), carfilzomib (17%), lenalidomide (15%), and thalidomide (12%). At data cutoff, 53 (24%) pts had died. Median OS was 36.7 (95% CI: 24.4-NR) mos, with 79% of pts alive at 12 mos (Figure). Regarding safety, ixazomib and lenalidomide dose reductions were required in 16% and 36% of pts, respectively, including 10% and 21% who required dose reductions due to AEs. Conclusions These findings show that the effectiveness of IRd in routine clinical practice (ORR 74%, median PFS 21.6 mos) is comparable to the efficacy of IRd reported in the registrational TOURMALINE MM1 trial (ORR 78%, median PFS 20.6 mos). IRd is well tolerated with no new safety signals, and low rates of dose reductions due to AEs for ixazomib (10%) and lenalidomide (21%). Outcomes should be interpreted with caution due to limited maturity of data.

Description: Background Ixazomib (ixa), the first oral proteasome inhibitor, is approved in combination with lenalidomide (len)-dexamethasone in 〉50 countries globally, including the US and EU, for the treatment of relapsed/refractory MM (RRMM) pts who have received ≥1 prior therapy. Outcomes and tolerability in routine clinical practice often differ from data reported in clinical trials for novel-agent-based MM therapies; however, data directly comparing efficacy in clinical trials with effectiveness in routine clinical practice of new MM agents and regimens are currently limited. To evaluate the effectiveness of IRd in RRMM pts in routine clinical practice, we performed a pooled analysis of individual pt-level data for IRd-treated RRMM pts from the ongoing INSIGHT MM (NCT02761187) study and from the Czech RMG. INSIGHT MM is the largest global, prospective, observational MM study conducted to date, which is currently enrolling ~4200 adult pts with newly diagnosed MM or RRMM from Europe (EUR), the US, Asia, and Latin America. The Czech RMG was established by the Czech Myeloma Group in 2007 and comprises clinical data for 〉6000 MM pts enrolled at 19 Czech and 4 Slovak centers. Methods RRMM pts with 1-3 (INSIGHT MM) or ≥1 (RMG) prior therapies who had been treated with IRd were identified. INSIGHT MM pts required prospectively collected data on IRd therapy; pts who received another regimen or additional treatment within the same line of therapy as IRd were excluded. RMG pts from Czech centers who received IRd were included using the same eligibility criteria as the INSIGHT MM study. Individual pt-level data on demographics, disease characteristics, treatment history, effectiveness, and safety for IRd-treated RRMM pts from INSIGHT MM and the Czech RMG were integrated and analyzed. Best response and PFS were determined as per the assessment of the treating physician or local investigator, utilizing IMWG criteria. Descriptive analyses were performed on the integrated data as well as on data from INSIGHT MM and from the Czech RMG. PFS, TTNT, DOT, and OS were estimated using Kaplan Meier methodology. Results Overall, 163 IRd-treated RRMM pts from 9 countries were included in the analysis (50 INSIGHT MM, 113 Czech RMG); of these, 146 (90%) were from EUR, 16 (10%) from the US, and 1 (1%) from Taiwan. Median age was 67 (range 39-84) yrs, with 23 (14%) pts aged 〉75 yrs; 86 (53%) pts were male. At initial diagnosis, 38%/36%/26% of pts had ISS Stage I/II/III disease; median time from diagnosis to initiation of IRd treatment was 42.6 mos; 71% of pts had ECOG PS ≥1. Most pts (65%) had IgG MM, and 14% had extramedullary disease. Overall, 50%/30%/20% of pts received IRd as 2nd/3rd/≥4th-line therapy. The most common reasons for starting IRd therapy were relapse/progression (90%), including bone lesions (53%), and anemia (14%). Overall, 61% of pts had received prior stem cell transplant; prior therapies included bortezomib (bor) in 89% of pts, thalidomide (thal) in 42%, len in 21%, carfilzomib (car) in 11%, daratumumab (dara) in 3%, and pomalidomide (pom) in 2%. Median DOT was 14.0 mos; 101 (62%) pts were on treatment at data cut-off. Data on best response to therapy were available for 105 pts; among these, ORR (partial response or better) was 74%, with 31% ≥VGPR (Table); ORR with IRd as 2nd/3rd/≥4th-line therapy was 91%/57%/47%, including 41%/25%/11% ≥VGPR. Median time to first response was 1.1 mos for Czech RMG pts; median time to best response was 3.7 mos for INSIGHT MM pts. Overall, median PFS was 20.9 (95% CI: 13.0-28.7) mos, with a 12-mo rate of 65% (Table). Median PFS with 2nd/3rd/4th/〉4th-line therapy was NR/23.2/14.2/5.1 mos. Median TTNT was 26.2 (95% CI: 9.6-42.8) mos, with a 12-mo rate of 73% (Table). Overall, 37 (23%) pts received subsequent therapies including bor (24%), pom (24%), thal (16%), dara (16%), car (14%), or len (8%). Median OS was not reached, with 81% of pts alive at 12 mos (Table). Ixa and len dose reductions were required in 15% and 30% of pts, respectively, with 11% and 21% of pts, respectively, requiring dose reductions due to AEs (Table). Conclusions These findings show that the effectiveness of IRd in routine clinical practice, including an ORR of 74% and a median PFS of 20.9 mos, is comparable to the efficacy of IRd reported in the TOURMALINE-MM1 trial (ORR 78%, median PFS 20.6 mos). IRd is well tolerated in RRMM pts treated in routine clinical practice, with low rates of dose reductions due to AEs for ixa (11%) and len (21%). Table. Table.

Description: Abstract 2873 Poster Board II-849 Destructive vertebral lesions are a common source of morbidity for patients with cancer. Balloon kyphoplasty (BKP) is a minimally invasive surgical procedure for patients with painful vertebral compression fractures (VCFs) with the goal of reducing pain and disability. We report the final results of the first randomized trial among cancer patients with VCFs to assess the efficacy and safety of BKP. Twenty-two multinational sites enrolled 134 patients after consent and ethical review board approval. Adult patients diagnosed with cancer and ' 3 painful VCFs were randomly assigned to BKP or nonsurgical management (NSM) and followed for 12 months. Patients were excluded with primary bone tumors, osteoblastic tumors or solitary plasmacytoma at the fracture site, or spinal cord compression. The primary objective was to determine the change in the Roland-Morris Disability questionnaire (RMDQ), a 0- (no disability) to 24-point (maximum disability) instrument validated for assessing back-specific physical functioning, at one month. Following this assessment, cross-over to BKP was allowed in the NSM arm. Patients were randomized to BKP (N=70) or NSM (N=64). Five patients withdrew early from the study without significant baseline data; the 3 patients assigned to BKP did not undergo the procedure. Thus, 68 BKP and 61 control patients were evaluable. Mean patient age was 64 years, 58% were female, and tumor types included multiple myeloma (38%), cancers of the breast (22%), lung (8.5%), prostate (6.2%) and other sites (26%). At baseline, 35% of patients were currently on daily corticosteroids, 50% had received bisphosphonates within 12 months of study entry, 49% had received prior radiation (52 % to the spine), and 67% of patients were previously treated with chemo/hormonal therapies. VCFs were identified in a single (34%), two (26%) or three (40%) sites. Mean baseline RMDQ scores were similar between the groups; 17.6 and 18.2 points for BKP and NSM patients, respectively. However, at one month, there was an improvement for patients randomized to BKP of −8.3 points (95% CI −6.4 to −10.2) whereas those receiving NSM showed no significant change (0.1 points, 95% CI 1.0 to −0.8; p

Description: Introduction: Lenalidomide (L) is an immunomodulatory compound, or IMiD®, which has impressive activity against both relapsed/refractory (RRMM) and newly diagnosed MM (NDMM). Although approximately 15% of NDMM patients (pts) treated with thalidomide (another IMiD®) plus dexamethasone (D)(TD) will develop thromboembolic events (TEEs), less is known about the thrombotic risk associated with LD. In 2 large Phase III studies comparing LD to D + placebo (P)(DP) in RRMM, which did not include routine thrombosis prophylaxis, the overall rate of TEEs in the LD groups were 8 and 14% versus 4% for those treated with DP. Here we describe an unexpectedly higher incidence of TEEs among the first 21 pts enrolled in a Southwest Oncology Group (SWOG) double-blinded Phase III study (S0232) comparing LD to DP in NDMM pts. Methods: Pts received L/P 25 mg/day on days 1–28 plus D 40 mg/day on days 1–4, 9–12, 17–20 for three 35-day induction cycles, followed by L/P 25 mg/day on days 1–21 plus D 40 mg/day on days 1–4, 15–18 in repeating 28-day maintenance cycles. The incidence of TEEs for pts on LD and DP were compared using Fisher’s exact test (two-sided). Baseline clinical data were compared for pts who developed thromboses versus those who did not. Baseline labs, including hemoglobin, platelet count, PT, PTT, D-dimers, fibrinogen, vWF activity, Protein C, Protein S, activated protein C resistance, factor VIII level, and thrombin-antithrombin complexes, were also assessed. Results: Nine of 12 NDMM pts (75%) randomized to LD developed TEEs, compared to zero of 9 (0%) treated with DP (p = 0.0011). All events were lower extremity deep vein thromboses except for one ischemic stroke. Events occurred after a median of 50 days of therapy. There was no association between myeloma stage, pt age or gender, or M-protein Ig subtype and the risk of thrombosis. Although baseline fVIII and vWF levels were elevated in the majority of pts (median 169 and 164.5, respectively) neither these nor other coagulation lab findings correlated with the risk of thrombosis. In all cases except the one pt who suffered a stroke, LD was resumed after full anticoagulation was instituted. Discussion: The 75% incidence of thrombosis for the first 12 newly diagnosed pts treated with LD on S0232 was much higher than expected. No other predictive risk factors, including coagulation-related laboratory abnormalities, were identified. The incidence of thrombosis for pts with NDMM treated on a prior Phase II study of LD administered in 28-day cycles with daily ASA prophylaxis (325 mg/day) was extremely low. This experience, plus evidence that ASA (81 mg/day or 325 mg/day) reduces the risk of TEEs in pts treated with TD or T plus chemotherapy, prompted us to amend the protocol to include ASA 325 mg daily for all pts. The impact of ASA prophylaxis on the incidence of TEEs in pts enrolled subsequent to the 21 pts described here will be reported at the meeting.

Description: Abstract 3223 Poster Board III-160 There are concerns that prolonged exposure to lenalidomide (len) impairs the peripheral blood progenitor cell (PBPC) yield in patients (pts) undergoing autologous peripheral blood stem cell transplant (ASCT) for multiple myeloma. To evaluate the effect of len on PBPC yield, we retrospectively analyzed 144 consecutive pts undergoing PBPC harvest prior to ASCT for multiple myeloma between July 1, 2007 and June 30, 2009. Exclusion criteria included prior ASCT or prior treatment with an alkylating agent. Of the evaluable patients, 67 pts received at least one cycle of len as part of their pre-harvest therapy (median # of cycles 4 (range 1-28)) and 63 received non-len containing regimens. Median age for all pts was 57 years and was similar between the two groups. Initial PBPC harvest was unsuccessful (defined as collection of

Description: Background: Melphalan in combination with dexamethasone is an active and the standard regimen in AL amyloidosis. Unfortunately very often patients relapse and other drugs are needed. Bendamustine is a bifunctional alkylating agent approved for the treatment of CLL, NHL, and MM in Europe and the US. But its safety and efficacy in AL amyloidosis is not known. In an effort to investigate the activity of Ben/Dex and improve the outcome of patients with relapsed AL we conduct a multi-center, Phase 2 study of Ben/Dex in AL (NCT01222260) and report data of an updated unplanned interim analysis. First data were reported at ASH 2014 (Abstr.3480). Methods: All patients had relapsed AL after a median of 2 prior therapies (range 1-4). Patients with very advanced cardiac involvement (NYHA Class IIIB/IV) were excluded. Patients with NYHA Class IIIA, NT-proBNP ≥ 1800 ng/L or BNP ≥ 400 ng/L, abnormal cTnT or cTnI could be included after evaluation by cardiology to determine the risk associated with the treatment. Patients with a CrCl ³ 15 mL/min were considered for the trial if they were not in active renal failure. This Phase IIa clinical trial uses a two-stage optimal Simon design enrolling 13 patients in the first stage. Since at least three patients experienced hematologic PR or better, the trial proceeded to the second stage treating an additional 16 patients. If 9 or more patients out of the total of 29 patients evaluable for response experience a hematologic PR or better, the treatment will be considered worthy of further development. The primary objective is to determine the partial hematologic response rate (PR). Secondary objectives included overall hematologic response (OHR) rate, organ response rate (OrRR) (Palladini et al., JCO 2012), time to failure (TTF), toxicities (adverse events at least possibly related to treatment), overall survival (OS) and the assessment of expression of genes associated with ER stress. Patients were assigned to bendamustine according to CrCl: CrCl ≥ 60 mL/min: 100 mg/m2 IV on day 1 and 2 of each cycle, CrCl 59-15 mL/min: 90 mg/m2 IV on day 1 and 2 of each cycle. The option to dose escalate was available to qualifying subjects including escalating to dose level (+)1: 120 mg/m2 (if CrCl ≥ 60 mL/min at the time of inclusion into the study) and 100 mg/m2 (if CrCl 59 - 15 mL/min at the time of inclusion into the study). Dexamethasone was started at 20-40mg weekly according to the performance status of the patient. The duration of each cycle was 28 days. Results: As of 7/15/15, 26 patients have received treatment and 28 patients have been enrolled. Median age of enrolled patients was 66 (range 44-77). Enrolled patients received a median of 1.5 prior regimens (range 1-4). Twelve of the enrolled patients received prior autologous stem cell transplant. Median number of cycles for treated patients is 3.5 (range is 1-12), with 4 patients still receiving treatment. Of note, only 2 patients discontinued treatment due to disease progression. Only 9 patients discontinued treatment due to AE. Most common drug-related AEs (all grades, 〉25%) included fatigue (39%), nausea (35%) and Anemia (27%),. No grade ≥3 drug-related AE occured in 〉20% of patients. Of note, no cardiac events were observed, including any increase in NT-proBNP.Of 24 patients eligible for response evaluation, 11 (46%) have responded hematologically, including (≥PR 42%, CR 4%). The median time to best response of treatment (partial response or better) was 1.57 months (range 0.97 to 15.1 months). The CR occurred in a patient after 5 cycles suggesting that this heavily pretreated patient population needs longer treatment to achieve response. Better responses were especially observed in less heavily treated patients. With a median follow-up of 13.4 months (range 1.5 to 30.3 months) the median OS has not been reached yet (Figure 1). The median PFS is 11.5 months (95% CI,1.5-29.1months) (Figure 2). Conclusions: In our updated unplanned interim analysis we found that Bendamustine in combination with dexamethasone is feasible and effective in pretreated AL amyloidosis with impaired organ function (NYHA IIIB and creatinine clearance of 30-15 mL/min were allowed). Cardiac events related to Bendamustine were not observed. Preliminary hematologic response rates are promising in this pretreated patient population, and organ assessments are ongoing. Further study of this approach is warranted. Figure 1. Figure 1. Figure 2. Figure 2.
