Abstract Abstract 1940 The combination of Melphalan-Prednisone-Lenalidomide (MPR) has shown promising results in elderly newly diagnosed myeloma patients. In the transplant setting, low-dose chemotherapy (induction) precedes high-dose chemotherapy (autologous transplantation consolidation). This approach reduces tumor mass, with few side effects, before achieving the maximum cyto-reduction with autologous transplantation. The same approach has been designed for the elderly patients. Accordingly induction with lenalidomide plus corticosteroids precedes consolidation with MPR. A two-stage phase II clinical trial was planned to evaluate the safety and efficacy of Lenalidomide-Prednisone (RP) as induction, followed by Melphalan-Prednisone-Lenalidomide (MPR) as consolidation and Lenalidomide as maintenance in elderly myeloma patients. Unfit patients with newly diagnosed symptomatic myeloma older than 65 years were enrolled. No exclusion criteria were included in the protocol, to avoid the selection of fit elderly subjects only. Patients with low blood count, abnormal performance status, hepatic, renal, cardiac or pulmonary functions were enrolled. Patients received 4 RP courses (Lenalidomide 25 mg/day for 21 days every 4 weeks, plus Prednisone 50 mg three times/week for 4 weeks) followed by 6 MPR cycles (Melphalan 2 mg and Prednisone 50 mg three times/week, for 4 weeks plus Lenalidomide 10–15 mg/day for 21 days every 4 weeks) and maintenance with Lenalidomide alone (10 mg/day for 21 days every 4 weeks). Two different dose-levels of Lenalidomide were tested in combination with MP: 15 mg (dose-level 1) and 10 mg (dose-level 2). Each cohort included 12 patients, with additional 22 patients enrolled at dose-level 2. Patients were evaluated for efficacy and toxicity after completion of at least 2 MPR cycles. Forty-six patients (median age 75, range 65–88) were enrolled. Thirty-six patients were evaluable after a median of 7 cycles and a median follow-up of 8.5 months. During RP induction, the most frequent grade 3–4 hematological adverse events were neutropenia (19%), anemia (11 %), thrombocytopenia (6%). During MPR consolidation, grade 3–4 adverse events were neutropenia (45%), and thrombocytopenia (3%). Neutropenia was increased by the addition of melphalan, but both thrombocytopenia and anemia were reduced. Non-hematological toxicities were more frequent during RP cycles and reduced during MPR cycles (cutaneous rash and infections). After RP induction, at least partial response (PR) rate was 67%, at least very good partial response (VGPR) was 17%. After 2 MPR cycles, PR rate increase to 72%, including 22% of patients who achieved at least a VGPR. Conclusions. Induction with RP followed by consolidation with MPR showed a manageable safety profile and reduced the risk of anemia, thrombocytopenia and non-hematological toxicity in unfit elderly myeloma patients. These data will be updated at the meeting.

Abstract Abstract 1856 Poster Board I-882 Background: Lenalidomide is an analog of thalidomide that has shown significant clinical activity in patients with relapsed or refractory multiple myeloma (MM), both as a single agent and in combination with dexamethasone. Bendamustine is a bifunctional alkylating agent that is approved for the treatment of chronic lymphocytic leukemia and indolent non-Hodgkin's lymphoma that has progressed during or relapsed within 6 months following a rituximab-containing regimen. Bendamustine combined with lenalidomide may be an effective treatment option for MM patients, particularly those with preexisting or bortezomib-induced neuropathy. Our primary objective was to determine the maximum tolerated dose (MTD) and safety profile of bendamustine and lenalidomide when administered with dexamethasone for patients with relapsed or refractory MM. Methods: Patients aged ≥18 years with confirmed, measurable stage 2 or 3 MM that was refractory to or progressed after 1 or more prior therapies, including lenalidomide, received bendamustine by intravenous infusion on days 1 and 2, oral lenalidomide on days 1–21, and oral dexamethasone on days 1, 8, 15, and 22 of each 28-day cycle. Treatment was continued until a plateau of best response, as determined by the IBMTR/ABMTR, was reached. Study drug doses were escalated through 4 levels (Table), with 3–6 patients enrolled at each level depending on the rate of dose-limiting toxicity (DLT). After determining the MTD, up to an additional 12 patients will be enrolled in an MTD expansion arm to better evaluate toxicity and clinical activity. Secondary endpoints included preliminary efficacy, as evidenced by objective response, time to disease progression, and overall survival. Results: To date, 11 patients have been enrolled, with a median age of 63 years (range, 38–75 years). The MTD of bendamustine and lenalidomide has not been identified at this point; currently, patients are enrolling on dose level 3 with 100 mg/m2 bendamustine and 10 mg lenalidomide. Thus far, DLT included 1 grade 4 neutropenia at dose level 2. Nine of 11 patients are currently eligible for response assessment. A partial response was observed in 67% of patients, including 1 very good partial response and 5 partial responses (PR). Two patients experienced stable disease and 1 exhibited progressive disease. Grade 3/4 adverse events included grade 3 neutropenia, thrombocytopenia, anemia, hyperglycemia, and prolonged QTC, and 1 grade 4 neutropenia. Conclusions: Bendamustine, lenalidomide, and dexamethasone form a well-tolerated and highly active regimen even in heavily pretreated MM patients, with a PR rate of 67%. Additional updates on response and MTD will be available at the time of presentation.

Abstract Background Carfilzomib is a novel second generation proteasome-inhibitor with significant anti MM activity and favorable toxicity profile, including very limited neurotoxicity and neutropenia. This Phase I/II study was designed to determine the maximum tolerated dose (MTD) of once weekly carfilzomib combined with cyclophosphamide-dexamethasone (wCCd) and to assess safety and efficacy of this combination in elderly patients with newly diagnosed MM. Here we report the first findings from the Phase I dose-escalation and expansion portions. Enrolment in the phase II portion is ongoing. Methods In the Phase I, the standard 3+3 dose-escalation scheme was adopted, with Carfilzomib as the only escalating agent starting at 45 mg/m2 (level 0), maximal planned dose 70 mg/m2 (level 2), and 36 mg/m2, if needed (level -1), given IV on days 1, 8, 15 in 28-day cycles. Oral cyclophosphamide was administered at 300 mg/m2 on days 1, 8, 15 and oral dexamethasone at 40 mg on days 1, 8, 15, 22 for all dose levels. Dose escalation of Carfilzomib was based on dose-limiting toxicities (DLTs) occurring in cycle 1. After completion of 9 cycles, patients receive 28-day maintenance cycles with Carfilzomib (days 1, 8, 15) at the maximum tolerated dose (MTD) defined by the Phase I study until disease progression or intolerance. The objectives were to determine the MTD and assess activity and safety. Results As of June 15, 2014, 28 newly diagnosed MM patients were enrolled. Median age was 74 years, 29% of patients were older than 75 years, 36% had ISS stage III, 24% had unfavorable FISH profile [t(4;14) or t (14;16) or del17p]. Twelve patients were enrolled in the Phase I portion of the study. At dose level 0 (Carfilzomib 45 mg/m2) no DLT was reported; at dose level 1 (Carfilzomib 56 mg/m2), 1 of 6 patients experienced DLT, consisting of grade 3 creatinine increase; at dose level 2 (Carfilzomib 70 mg/m2) no DLT occurred. The MTD of weekly Carfilzomib was thus established as 70 mg/m2. Toxicity and response data are available for 25 patients, who have completed at least the first cycle; 3 patients are currently receiving their first cycle of treatment. Grade 3-4 drug-related adverse events occurred in less than 15% of patients and included neutropenia (12%, 3 patients), anemia (12%, 3 patients), acute pulmonary edema (8%, 2 patients), pulmonary embolism (4%, 1 patient), creatinine increase (4%, 1 patient), nausea (4%, 1 patient), and fatigue (4%, 1 patient). No peripheral neuropathy was observed. Overall, the wCCd regimen was well tolerated, 3 patients (12%) required Carfilzomib dose reduction (grade 3 creatinine increase, grade 3 transaminase increase and grade 2 fever) and 3 patients (12%) required drug discontinuation due to adverse events (2 acute pulmonary edemas and 1 creatinine increase). Patients received a median of 5 cycles (range 1-9). After 4 induction cycles, 83% of patients achieved at least partial response, 39% at least very good partial response, and 22% complete response. Responses improved over time, as shown in table 1. During the study, only 2 patients progressed and 1 patient died, due to acute pulmonary edema considered probably related to treatment. Conclusions This is the first prospective study evaluating once weekly carfilzomib in treatment-naïve MM. wCCd therapy appears safe and effective in newly diagnosed MM patients. Responses became deeper with subsequent cycles and toxicities were manageable. The response rate observed with weekly carfilzomib compares favorably with similar studies with standard twice weekly carfilzomib infusion. Updated results will be presented at the meeting.

Abstract Introduction: CPX-351 (Vyxeos ©; daunorubicin and cytarabine liposome for injection) is a dual-drug liposomal encapsulation of daunorubicin and cytarabine in a synergistic 1:5 molar drug ratio that is FDA approved for treatment of adults with newly diagnosed therapy-related AML or AML with myelodysplasia-related changes. Secondary AML is clinically and biologically similar to MDS, sharing many of the same genetic mutations. We hypothesize that CPX-351 therapy may result in deeper responses than traditional therapy with hypomethylating agents, with acceptable tolerability, and translate into better outcomes in the MDS population. This is a multicenter, dose-escalation and safety expansion study (NCT03572764) to investigate induction and consolidation therapy with CPX-351 in a transplant eligible, higher risk MDS population. Methods: Two dose levels were investigated in the dose-escalation portion. Induction Dose Level 1: (daunorubicin 29 mg/m 2 and 65 mg/m 2 cytarabine) liposome on days 1, 3, 5; and Induction Dose Level 2: (daunorubicin 44 mg/m 2 and 100 mg/m 2 cytarabine) liposome on Days 1, 3, 5. The primary objectives were to evaluate safety and to determine the dose-limiting toxicities (DLTs) and recommended Phase 2 dose (RP2D). DLTs were assessed during the induction period (up to day 56 to evaluate for prolonged myelosuppression). Additionally, a dose expansion (for up to 20 treated patients) was performed at the RP2D. After induction, patients could receive up to two cycles of consolidation per dose level: Dose Level 1, (daunorubicin 14.3 mg/m 2 and 32 mg/m 2 cytarabine) liposome on Days 1 and 3; or Dose Level 2 (daunorubicin 29 mg/m 2 and 65 mg/m 2 cytarabine) liposome on Days 1 and 3. After induction, the patient could proceed to alloHCT at any time at the discretion of the treating physician. Key eligibility criteria included MDS patients who were naïve to hypomethylating agents, aged 18-70 years, an IPSS-R score > 3 (Intermediate, High or Very High Risk), ≥ 5% bone marrow myeloblasts, and suitable candidates for cytotoxic induction therapy and allogeneic hematopoietic cell transplant (alloHCT). Key secondary endpoints were day 30 and 60 post-induction mortality, the proportion of patients proceeding to alloHCT, and response assessments per IWG 2006 criteria. Results: As of abstract submission, 19 patients have been treated and dose escalation is complete. The dose escalation portion included 12 patients (Dose Level 1, n=6; Dose Level 2, n=6), and the safety expansion to date includes 7 patients treated at Dose Level 2. The median age was 64 years (range, 18-68), 67% were female, and the IPSS-R risk categories were as follows: intermediate (n=1, 5%), high (n=10, 53%) and very high (n=8, 42%). There were no DLTs in either Dose Level 1 or Dose Level 2, and Dose Level 2 was selected for safety expansion. Treatment-emergent adverse events (TEAEs) were evaluated in the 18 patients who had completed induction (Table). The most common TEAEs were hematologic, as expected. The most common non-hematologic TEAEs were febrile neutropenia (n=13, 72.2%), hypertension (n=9, 50%), and sepsis (n=5, 27.8%). SAEs included febrile neutropenia (n=5), sepsis (n=2), lower GI hemorrhage (n=2, two instances in the same patient), atrial fibrillation (n=1), pneumonitis (n=1), and catheter related infection (n=1). To date, the 30 and 60 day mortality is 0% and 5% (n=1), respectively, with the 1 death unrelated to therapy and due to progression of disease to AML. Of the 19 patients, 13 have received alloHCT with 4 still potentially alloHCT candidates. Of response evaluable pts (n=18, 1 pt pending response evaluation at data cutoff), the overall response rate was 78% with best overall responses of CR (n=4), mCR (n=10), stable disease (n=2), progressive disease (n=2) and pending (n=1). Of the 10 patients with mCR, 3 also had hematologic improvements. Conclusions: CPX-351 (daunorubicin 44 mg/m 2 and 100 mg/m 2 cytarabine) liposome on Days 1, 3, 5, has demonstrated a tolerable safety and promising efficacy profile when used in a transplant eligible, higher risk MDS population, warranting further study. Updated safety and efficacy outcomes will be presented at the meeting. Figure 1 Figure 1. Disclosures Jacoby: Abbvie: Research Funding; Jazz: Research Funding.

Abstract Abstract 2949 Background: The treatment of patients with newly diagnosed multiple myeloma (MM) with a 3 week cycle of lenalidomide (R), bortezomib (V), and dexamethasone (D) (R 25 mg days 1–14, V 1.3 mg/m2 day 1, 4, 8, 11, and D 20 mg day 1, 2, 4, 5, 8, 9, 11, 12) is associated with unprecedented response rates (Richardson et al. Blood 2010) (see Table 1). Partial response (PR) was 100% and 74% of patients achieved a very good partial response (VGPR) or better with RVD treatment. However, these responses come at the expense of an 80% rate of sensory neuropathy (27% grade 2 and 2% grade 3) and 32% with neuropathic pain (11% grade 2, 3% grade 3). As a result, only 59% of patients received all 3 agents and at least 1 dose modification of bortezomib was required in 44% of patients including 15% for neuropathic pain, 14% for sensory neuropathy, and 8% for fatigue Recent data confirm that a decrease in the dose intensity of bortezomib (for example with weekly dosing) is associated with significantly less toxicity, but importantly (at least in the context of combination chemotherapy) without a decrease in efficacy (Bringhen et al., Blood 2010). In this retrospective study, we examine the efficacy and toxicity of a 28 day RVD treatment schedule for patients with newly diagnosed MM. Methods: All patients with newly diagnosed, symptomatic MM who received front-line RVD on a 28 day schedule where R 25 mg was given days 1–21, V 1.3 mg/m2 was given on day 1, 4, 11, 18 and D 20 or 40 mg was given on day 1, 4, 11, 18 (see Table 2) were selected for this analysis. Patients were excluded if they had received any previous systemic anti-MM therapy (except prior corticosteroids for hypercalcemia or spinal cord compression). Patients who were empirically dose reduced for comorbidities were not excluded. All patients received prophylaxis for venous thromboembolism and VZV. Results: A total of 38 patients met the inclusion criteria for analysis. The median age at start of treatment was 59.5 years. The ISS distribution was Stage I 73% of patients, Stage II 16%, and Stage III 11%. Median treatment length was 4.5 cycles (range 3–12). After four cycles of treatment with VRD, the overall response rate was 97%, which included 63% VGPR or better (24/38) and 34% PR (13/38). 1 remaining patient had an MR (49% reduction in m spike). 32% of patients (n=12/38) went on to stem cell transplantation after four cycles of treatment while the rest were placed on maintenance therapy. With a median follow up of 9 months, no patients have had disease progression. Impressively, the rate of all grades of neuropathy at four cycles was 37% (n=14/38) with 21% (n=8/38) grade 1 sensory neuropathy, 11% (n=4/38) grade 2 neuropathy with pain and 5% grade 3 (n=2/38). There were no other hematologic or non-hematologic grade 3 or 4 toxicities. Conclusion: Despite a decrease in the dose density of bortezomib and dexamethasone, the continued synergy of these agents with a full 21 day course of lenalidomide provides excellent efficacy with reduced rates of toxicity. The 28 day schedule of RVD is an efficacious, convenient, and well tolerated treatment regimen for patients with newly diagnosed symptomatic MM. The subcutaneous administration of bortezomib on this 28 day schedule may allow even further reductions in toxicity without sacrificing efficacy.

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

Abstract Abstract 631 Introduction: In relapsed and/or refractory MM, the combination of carfilzomib (CFZ) with lenalidomide (Len), and low-dose dexamethasone (Dex) (CRd) has shown very promising efficacy (78% ≥partial response [PR], 40% ≥very good partial response [VGPR], and 24% CR/nCR) and good tolerability including a low rate of peripheral neuropathy (Wang et al, ASCO, 2011). In a Phase I/II study of newly diagnosed MM, the regimen was well tolerated in the Phase I portion of the study up to a maximum dose of CFZ 36 mg/m2, Len 25 mg, and Dex 40 mg, and very active with 96% ≥PR, 70% ≥VGPR, and 55% CR/nCR (Jakubowiak et al, ASH 2010). The lack of overlapping toxicities has allowed these agents to be used at full doses and for extended periods. Here we report the results for all patients (pts) enrolled in both phases of this first prospective trial of CFZ combination in new MM. Methods: In the initial eight 28-day cycles, pts were treated with CFZ at 20 mg/m2, 27 mg/m2 (Phase I), and 36 mg/m2 (Phase I and II), given IV on days 1, 2, 8, 9, 15 and 16, Len at 25 mg PO (days 1–21), and Dex at 40/20 mg PO weekly (cycles 1–4/5–8). Pts achieving ≥PR could proceed to stem cell collection (SCC) using growth factors alone (protocol recommendation) and autologous stem cell transplant (ASCT) after 4 cycles. Per protocol, ASCT candidates were offered the option to continue CRd treatment after SCC. After 8 cycles, pts received 28-day maintenance cycles of CFZ (days 1, 2, 15, 16), Len days 1–21, and Dex weekly at the doses tolerated at the end of 8 cycles. Responses were assessed by IMWG criteria with the addition of nCR. Results: Enrollment was completed (53 pts): 4 pts at CFZ 20 mg/m2, 13 at CFZ 27 mg/m2 and 36 at CFZ 36 mg/m2 (18 in Phase I and 18 in Phase II). Median age was 59 years (range 35–81; 23 pts ≥65), 60% had ISS stage II/III, and 33% (of 49 with available data) had unfavorable cytogenetics: del 13 or hypodiploidy by metaphase, or t(4;14), t (14;16), del 17p by FISH. As of June 30, 2011, toxicity data (cycles 1–8) were available for 51 pts. Hematologic toxicities were reversible and included Grade (G) 3/4: anemia (18%), neutropenia (12%), and thrombocytopenia (10%). The most common non-hematologic toxicities (all G) were hyperglycemia (76%), hypophosphatemia (61%), and infection (53%). G3/4 non-hematologic AEs included hyperglycemia (24%), DVT/PE while on ASA prophylaxis (10%), infection (6%), and mood alteration (2%). PN was limited to G1/2 sensory (24%). Forty-five pts continue treatment with 22 pts in the maintenance phase. Six pts discontinued treatment: 2 proceeded to ASCT, 1 due to toxicity, and 3 due to events unrelated to treatment or per pt wish. The majority of pts did not require dose modifications, either in the initial (31%) or in the maintenance (25%) phase. After a median of 8 cycles (range 1–20), the best responses per IMWG criteria for 49 response-evaluable pts (all pts who completed 1+ cycle) are shown in the Table. Responses were rapid with 46/49 pts achieving at least PR after 1 cycle, and improved with the duration of treatment reaching 100% ≥PR after 4 cycles and 100% ≥VGPR, 79% CR/nCR after 12 cycles. Responses were deep even at the 2 lower dose levels with the majority of pts at 36 mg/m2 still early in treatment. Responses in pts with unfavorable cytogenetics were similar to response rates in all remaining pts and included a 100% ≥PR in 6 pts with del 17p. Twenty-four pts proceeded to SCC after a median of 5 cycles of CRd (range 4–9); using growth factors only in 23 pts and cyclophosphamide and growth factors in 1 pt, with a median 6.55 × 106 CD34+ cells/kg collected (range 3.75–9.6); all resumed CRd treatment. After a median of 9.5 months of follow-up, only 1 pt has progressed, and all are alive Conclusions: CRd is highly active and well-tolerated allowing the use of full doses for an extended time in newly-diagnosed MM pts with limited need for dose modification. Responses are rapid and improve over time reaching 100% ≥VGPR and early time-to-event data are very encouraging. These results compare favorably to the best frontline regimens in MM.

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

Abstract Background Rd and MPR are effective treatments in newly diagnosed multiple myeloma (NDMM) patients (pts). In this study we compared a non-alkylating containing regimen (Rd) vs alkylating-based regimens (MPR/CPR) in elderly transplant ineligible NDMM pts. Methods Patients were randomized (2:1) to receive nine 28-day cycles of MPR/CPR or Rd. MPR: lenalidomide 10 mg/day for 21 days; melphalan orally 0.18 mg/Kg for 4 days in pts 65-75 years old and 0.13 mg/Kg in >75 years pts; prednisone 1.5 mg/Kg for 4 days; CPR: cyclophosphamide orally 50 mg/day for 21 days in pts 65-75 years old and 50 mg every other day (eod) in >75 years pts; lenalidomide 25 mg/day for 21 days; prednisone 25 mg every other day. Rd: lenalidomide 25 mg/day for 21 days; dexamethasone 40 mg on days 1,8,15 and 22 in pts 65-75 years old and 20 mg in those >75 years. After induction, patients were randomized to receive maintenance with lenalidomide alone (10 mg/day for 21 days) or with prednisone (25 mg eod on days 1-28), until disease progression. The primary endpoint was progression-free survival (PFS). Results Between October 2009 and October 2012, 659 pts were enrolled ( MPR/CPR:439 and Rd:220), and 641 pts were evaluable (MPR/CPR:430 and Rd:211). Patient characteristics were well balanced in the 2 groups: median age was 73 years in both groups, 38% of pts were older than 75 years, 27% had ISS stage III in both groups, 21% of patients both in the MPR/CPR and in the Rd groups had unfavorable FISH profile [t(4;14) or t (14;16) or del17p]. After induction, the response rates were similar in the 2 groups: at least PR rate was 75% versus 79% (p=0.52) and CR rate was 9% versus 7% (p=0.35), in the MPR/CPR and Rd group, respectively. No significant difference in response rate were reported between two alkylating containing regimens. After a median follow-up of 21 months, the 2-year PFS was 55% in MPR/CPR and 49% in Rd (HR=0.86, 95% CI: 0.66-1.12, p=0.26), and 2-year OS was 84% in MPR/CPR and 80% in Rd (HR= 0.93, 95% CI: 0.60-1.41, p=0.71) At least one grade ≥3 hematological adverse event was reported in 51% with MPR/CPR and 29% with Rd (p<0.001), with a significant difference between the two alkylating agents (67% MPR and 31% CPR, p<0.001). At least one grade ≥3 extra-hematologic toxicities were similar in the two groups (31% with MPR/CPR and 28% with Rd, p=0.77). with no difference between two alkylating agents (31% both in MPR and CPR group). Second primary malignancies (SPM) were reported in 5 MPR patients (1 hematologic and 4 solid) in 1 CPR patient (hematologic) and in 2 Rd patients (both solid). Conclusion In a community-based population, triplet alkylating combinations did not lead to different PFS or OS clinical benefits over doublet therapy. Updated results will be presented at the meeting.

Background: Maintenance therapy with lenalidomide post-autologous stem cell transplantation (ASCT) has shown to improve progression-free survival (PFS) in multiple myeloma (MM), and has largely become the standard of care. However, toxicity leads to early discontinuation in nearly one-third of patients and additional options are needed (McCarthy, et al, JCO, 2017). Ixazomib is another maintenance option that has been shown to improve PFS; however, studies comparing lenalidomide and ixazomib are lacking. In this randomized phase 2 study, we analyzed the safety and efficacy of using lenalidomide and ixazomib as part of consolidation and maintenance therapies after ASCT (NCT02253316). Methods: Eligible patients, age 18-70 with newly diagnosed MM undergoing ASCT during first-line treatment, were consented prior to ASCT. Approximately 4 months following ASCT, patients received 4 cycles of consolidation therapy with IRd [ixazomib 4 mg on days 1, 8 and 15 of a 28-day cycle, lenalidomide 15 mg on days 1 through 21, and dexamethasone 40 mg on days 1, 8 and 15]. Primary data on IRd consolidation were presented at ASH 2018 (Abstract 109920). One month after the last consolidation cycle, patients were randomized (1:1) to maintenance therapy with single-agent ixazomib (4 mg on days 1, 8 and 15 of a 28-day cycle) or lenalidomide (10 mg daily months 1-3 followed by 15 mg for months 4+). The arms were stratified based on MRD-status post-consolidation. In total, 237 patients were enrolled from 10 US centers. This abstract coincides with planned interim analysis 3 which is the first comparison of ixazomib and lenalidomide maintenance. While the study was not powered to compare PFS between the two arms, the sample will provide a reasonable power to estimate non-inferiority. There is a planned stopping rule for non-inferiority set at a hazard ratio of &gt;1.3 in favor of lenalidomide. Secondary end-points include MRD-negativity following 12 cycles and toxicity. Results: At time of abstract submission, 215 patients had completed IRd consolidation and 191 had begun maintenance. 90 were randomized to ixazomib and 94 to lenalidomide. 7 patients were not randomized due to toxicity during consolidation; data from these patients are not included in the analyses. The characteristics of the two arms are summarized in Table 1. Hematologic toxicity has been infrequent with ixazomib with neutropenia and thrombocytopenia occurring in 11% and 23% of patients. In comparison, neutropenia and thrombocytopenia occurred in 45% and 35% of patients on lenalidomide. The most common non-hematologic toxicities in both arms have been GI-related and infections, both expected events. 16% of patients on ixazomib have experienced Grade 3-4 non-hematologic toxicity compared to 34% on lenalidomide. No grade 3 or higher peripheral neuropathy has been reported in either arm. 11% of patients on ixazomib have discontinued due to toxicity and another 9% have required a dose reduction to 3mg. Lenalidomide toxicity has led to discontinuation in 15% of patients and another 12% were dose reduced to 5mg. Only 45% of patients receiving 4+ cycles of lenalidomide were able to titrate to the 15mg dose. After a median follow-up of 11.2 months from randomization (19.7 months post-ASCT), 30% of patients on ixazomib have discontinued treatment due to disease progression. After a median follow-up of 12.3 months from randomization (20.2 months post-ASCT), 18% patients on lenalidomide have discontinued treatment due to disease progression. Conclusion: Ixazomib and lenalidomide maintenance have been well tolerated to date. A comparison of PFS is currently being conducted as part of interim analysis 3 and final results will be presented, representing the first report directly comparing lenalidomide and ixazomib maintenance.

Abstract Background: Isatuximab (ISA) is an anti-CD38 monoclonal antibody with multiple modes of action for killing tumor cells via direct tumor targeting and immune cell engagement. ISA, combined with bortezomib, has demonstrated strong potentiation in a multiple myeloma (MM) xenograft model (Clin Cancer Res 2014:20:4754). This supported evaluation of ISA with bortezomib combinations in pts with newly diagnosed multiple myeloma (NDMM) ineligible for transplant. In the initial cohort, ISA combined with bortezomib, cyclophosphamide, and dexamethasone (dex) was well tolerated with 73% of pts achieving very good partial response (VGPR) or better and 40% with complete response (CR) (Blood 2017; 130: 3160). The combination of bortezomib, lenalidomide, and dex (VRd) is also effective in NDMM (Lancet 2017:389:519-27). Here, we report initial data from a Phase Ib study of ISA plus VRd in pts with NDMM (NCT02513186). Methods: Pts with NDMM ineligible for transplantation were treated in 2 phases: induction and maintenance. Induction phase (four 6-week cycles [C]): ISA (10 mg/kg) on Day (D) 1, 8, 15, 22, 29 (C1), followed by D1, 15, 29 (C2-4); bortezomib (1.3 mg/m2) on D1, 4, 8, 11, 22, 25, 29, 32 (C1-4); lenalidomide (25 mg/day): D1-14 and D22-35 (C1-4); dex (20 mg/day): D1, 2, 4, 5, 8, 9, 11, 12, 15, 22, 23, 25, 26, 29, 30, 32, 33. Maintenance phase (4-week cycles): ISA (10 mg/kg) on D1, 15 (all cycles); lenalidomide (25 mg/day): D1-21 (all cycles); dex (40 mg): D1, 8, 15, 22 (all cycles), unless the pt was >75 years of age, then the dose was 20 mg. The primary objective was to evaluate safety and preliminary efficacy (overall response rate [ORR] and CR rate, [IMWG criteria]) of ISA plus VRd. Minimal residual disease (MRD) was evaluated using next generation sequencing (NGS) and flow cytometry (NGF) at a sensitivity of 10-6 in pts achieving VGPR or above. Here, we report results from a protocol-planned interim analysis. Results: All 22 pts were included in the safety analysis (pts who received ≥1 dose of ISA) and 14 were eligible for preliminary efficacy analyses (first 14 pts who completed the 4 induction cycles). Median age was 71 (range 63-77) years. At study entry, 6, 12, and 1 pt were International Staging System Stage I, II, and III, respectively. One pt had extramedullary plasmacytoma at baseline. At data cut-off (Mar 22, 2018), the median number of cycles was 5.5 (1-9). Three pts discontinued treatment (2 VGPR, 1 not efficacy-evaluable): 2 pts due to adverse event (AE); Grade (Gr) 3 infusion reaction (IR) (ISA-related; Gr 3 dyspnea, Gr 2 glottic edema, Gr 2 nasal edema, and Gr 2 generalized rash), and Gr 5 bacteremia (lenalidomide- and dex-related); and 1 pt withdrew consent; 19 (86%) pts are continuing treatment. Dose reduction of bortezomib, lenalidomide, and dex was required in 6 (29%), 4 (16%), and 5 (28%) pts, respectively. TEAEs occurred in 19 (86%) pts. Most frequent TEAEs (any Gr; excluding laboratory abnormalities) were constipation (10 pts [46%]), IRs and peripheral edema (9 pts [41%] each), asthenia, diarrhea, and peripheral sensory neuropathy (8 pts [36%] each), hypotension (7 pts [32%]), fatigue and respiratory tract infection (6 pts [27%] each), cough and dyspnea (5 pts [23%] each). Gr ≥3 AEs were reported in 10 (46%) and serious AEs (SAEs) in 4 (18%) pts. Treatment-related SAEs occurred in 2 (9%) pts (IR and pancreatitis). IRs were Gr 1/2 in all but 1 (5%) pt (Gr 3). Gr 3/4 laboratory hematologic abnormalities: lymphopenia (8/22), neutropenia (4/22), thrombocytopenia (4/22)VGPR, 1 partial response (PR) and 1 pt with stable diseaseMedian time to first response was 1.4 months (end of C1) and, with a median follow-up of 7.49 months (at cut-off date), no pt has progressed, with all except 3 pts continuing on therapy. Five (38.5%) of 13 pts achieved MRD-negative status (by NGF and NGS, or NGS only). Conclusion: These data suggest that ISA plus VRd followed by ISA plus Rd is well tolerated with a high ORR of 93%. All responders had VGPR or CR except 1 pt with PR. Quality of CR may have been underestimated due to ISA interference which could be resolved with an interference assay.
