Introduction: The nuclear export protein Exportin 1 (XPO1) is overexpressed in a wide variety of cancers including multiple myeloma. Selinexor is a novel, first-in-class selective inhibitor of nuclear export (SINE), which blocks XPO1, forcing the nuclear retention and activation of tumor suppressor proteins. Selinexor in combination with low dose dexamethasone (Sel-dex) was recently approved based on data from the STORM study, wherein Sel-dex induced an overall response rate (ORR) of 26.2% in patients with penta-exposed, triple-class refractory multiple myeloma. Lenalidomide in combination with dexamethasone has been approved for the treatment of relapsed/refractory multiple myeloma with an ORR of 60-76%. The STOMP study assessed the efficacy and safety of the all oral combination of selinexor, lenalidomide and dexamethasone (SRd) in patients with relapsed/refractory and newly diagnosed multiple myeloma. We previously reported the recommended phase 2 dose (RP2D) of once weekly selinexor 60 mg, lenalidomide 25 mg and dexamethasone achieved an ORR of 92% in patients with RRMM who were lenalidomide naive. Here we evaluated once weekly selinexor in combination with lenalidomide and dexamethasone in patients with newly diagnosed multiple myeloma. Methods: STOMP is a multicenter, open-label study with a dose escalation (phase 1) and expansion (phase 2) to assess the maximum tolerated dose, RP2D, efficacy and safety of SRd in patients with newly diagnosed multiple myeloma. Patients with newly diagnosed multiple myeloma were eligible if they had symptomatic myeloma per the International Myeloma Working Group (IMWG) guidelines with either hypercalcemia, renal failure, anemia, bone lesions (CRAB) criteria or myeloma defining events needing systemic therapy. Enrollment in this arm is ongoing. Results: As of July 01 2019, 8 patients (4 males and 4 females ) with newly diagnosed multiple myeloma were enrolled at the starting dose level of selinexor 60 mg on days 1, 8, 15, and 22; lenalidomide 25 mg daily 1-21and dexamethasone 40 mg weekly on a 28 day cycle. The median age was 74 years (range: 51-86 years). No dose limiting toxicities (DLT) were observed in 5 DLT evaluable patients, 3 patients were not DLT evaluable because 1 patient did not finish cycle 1 due to social reasons and 2 patients missed doses due to serious adverse events (SAEs) unrelated to study drugs.. Common treatment related hematologic AEs (Grades 1/2, ≥3) were neutropenia (0%, 75%), anemia (0%, 25%), and thrombocytopenia (0%, 25%). Common non-hematologic AEs were diarrhea (63%, 0%), nausea (50%, 0%), fatigue (0%, 38%) decreased weight (38%, 0%), constipation (25%, 0%), hypokalemia (25%, 0%), and hypomagnesemia (25%, 0%). Among 7 efficacy evaluable patients, 6 patients achieved a response (ORR of 86%) including 1 complete response, 1 very good partial responses, 4 partial responses (2 unconfirmed), and 1 patient achieved a minimal response. With a median follow-up of 6.1 months, median progression-free survival was not reached. Conclusions: The all oral combination of SRd has promising activity with 6 of 7 efficacy evaluable patients achieving an objective response in patients with newly diagnosed multiple myeloma and no new or unexpected safety signals.

Triplet Regimen

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

Abstract Abstract 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 Introduction: Venetoclax (Ven), an oral agent that targets the antiapoptotic protein, BCL-2, has demonstrated efficacy, as monotherapy and combined with proteasome inhibitor (PI) bortezomib, in relapsed/refractory (R/R) multiple myeloma (MM). We report preliminary safety and efficacy data for Ven combined with the second generation PI carfilzomib (K) and dexamethasone (VenKd) in R/R MM. Methods: In this ongoing phase 2, dose escalation study (NCT02899052), patients with R/R MM and no prior K exposure received VenKd on 28-d cycles in 4 dose finding and one expansion cohorts: Ven 400 mg/day + K 27 mg/m2 Day 1, 2, 8, 9, 15, 16 + dex 40 mg Day 1, 8, 15, 22 (Cohort 1), same regimen but with Ven 800 mg/day (Cohort 2), Ven 800 mg/day + K 70 mg/m2 Day 1, 8, 15 + dex 40 mg Day 1, 8, 15, 22 (Cohort 3/expansion cohort), or Ven 800 mg + K 56 mg/m2 Day 1, 2, 8, 9, 15, 16 + dex 40 mg Day 1, 2, 8, 9, 15, 16, 22, 23 (Cohort 4). Treatment continued until progressive disease (PD) or unacceptable toxicity. Results: As of June 11, 2018, 42 patients were enrolled. The median age was 66.5 years (min, max: 37, 79), 63% had ISS II/III disease, and 8 patients (19%) had t(11;14). Patients received a median of 2 prior therapies (range: 1 - 3), 93% had received prior PI (50% refractory), 62% were refractory to immunomodulatory therapies, and 33% double refractory. At the data cut off, 29 patients were still active and had completed ≥2 cycles and 13 patients discontinued with the primary reason being disease progression (n=4), death (n=3), physician decision (n=2), withdrawal of consent (n=2), lack of efficacy (n=1), and AE (n=1). All patients experienced at least one AE, and grade 3/4 AEs experienced by >10% of subjects included: decreased lymphocyte count (26%), decreased neutrophil count (14%), and hypertension (12%). Thirteen subjects experienced at least one serious AE. Maximum tolerated dose was not reached and Ven 800 mg/day + K 70 mg/m2 was selected for expansion. Ven mean (% coefficient of variation) maximum plasma concentration (Cmax) and area under the plasma concentration-time curve over 24 hours (AUC24) on Cycle 1 Day 15 were 2.7 (57) mg/mL and 33.1 (54) mg×h/mL, respectively, at 400 mg venetoclax (n=4); and were 2.42 (53) mg/mL and 38.7 (51) mg×h/mL, respectively, at 800 mg venetoclax (n=13) in the dose escalation cohorts. The overall response rate (ORR) was 78% and the very good partial response (VGPR) or better rate was 56% (Table). Median time from first dose to the data cut or discontinuation was 5.7 months (range: 0.9 - 16.3) and the median time to first response was 1.9 months (95% CI: 0.9, 9.2). ORRs for subgroups of interest are reported in the Table. Conclusions: The combination of VenKd appears tolerable with no new safety signals or changes in Ven pharmacokinetics. VenKd shows promising preliminary efficacy in R/R MM patient subgroups. Response rates were comparable in all high risk subgroups and overall population. However, the subset of patients with t(11;14) had the highest response. Overall, these results demonstrate that VenKd is a safe and efficacious regimen in R/R MM and support the continued study of VenKd.

Abstract Introduction - The nuclear export protein exportin 1 (XPO1) is overexpressed in a wide variety of cancers including multiple myeloma (MM). Selinexor is a first-in-class Selective Inhibitor of Nuclear Export (SINE) compound that binds and inactivates XPO1. Selinexor forces nuclear retention and reactivation of cell cycle regulators such as p53, IkB, and Rb. Pomalidomide/dexamethasone (Pd) is approved in relapsed/refractory MM (RRMM)with an overall response rate (ORR) of 30% and progression-free survival (PFS) rate of <4 months in patients (pts) having received a prior proteasome inhibitor (PI) and IMiD. Strategies to improve the ORR and PFS are needed. In murine MM models, the combination of selinexor with IMiDs shows synergistic anti-MM activity and good tolerability. Methods- Pts with RRMM who received ≥ 2 prior therapies including lenalidomide (len) and a PI were enrolled. Selinexor was evaluated in 2 different dosing schedules of once-weekly (QW, 60 or 80 mg) or twice-weekly (BIW, 60 or 80 mg), with pomalidomide (pom)3 or 4 mg PO daily, and dexamethasone (dex) 20 mg BIW or 40 mg QW. The primary objectives were to determine the maximum tolerated dose (MTD), recommended phase 2 dose (RP2D), safety, and preliminary efficacy of the combination of selinexor, pomalidomide, and low dose dex (SPd) in pts with RRMM. Results- As of July 20th2018, 34 pts (16 male / 18 female) have been enrolled. The median age is 61 years and patients received a median of 4 (range, 2 - 9) prior treatment regimens. Thirty-two patients were IMiD refractory (21 len, 11 pom/len). Six dose limiting toxicities (DLTs) were observed: G3 fatigue (60 mg BIW, pom 4 mg), G3 febrile neutropenia (FN) (60 mg BIW, pom 3 mg), G3 FN and G4 neutropenia (80 mg QW, pom 4), G3 thrombocytopenia (80 mg QW, pom 3 mg) and 4 missed doses in Cycle 1 due to symptomatic hyponatremia (80 mg BIW, pom 4 mg). Enrollment on selinexor 80 mg QW, pom 3 mg is ongoing. Common SPd treatment related adverse events included (all grades, grades 3/4): neutropenia (62%, 56%), thrombocytopenia (59%, 32%), anemia (53%, 29%), anorexia (56%, 0%), fatigue (50%, 9%), nausea (47%, 0% ). Thirty pts were evaluable for response, which is outlined in Table 1. Median PFS is 10.3 months with a median follow up of 9.4 months. Conclusions- Enrollment is ongoing to evaluate once weekly selinexor in combination with Pd , (SPd). This all-oral SPd combination has clinical activity with an ORR 55% in pom-naive pts with heavily pretreated MM compared to previously published data of 30% ORR for Pd alone. Similarly, the PFS on SPd is 10.3 months vs. <4 months for Pd alone. No unexpected adverse events were noted. Phase 1 dose escalation of the combination of SPd is ongoing to define the optimal RP2D.

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.

Abstract Introduction: Carfilzomib is an irreversible proteasome inhibitor that is approved as a single agent in the United States and other countries for the treatment of relapsed and refractory multiple myeloma (MM); carfilzomib in combination with lenalidomide (LEN) and dexamethasone is also approved in the United States for the treatment of relapsed MM. The approved dose and schedule of carfilzomib is a twice-weekly, 10-min intravenous (IV) infusion on days 1, 2, 8, 9, 15, and 16 of 28-day cycles (starting dose: 20 mg/m2 [days 1 and 2 of cycle 1]; escalated to a target dose of 27 mg/m2 thereafter). Here we present updated results from the multicenter, phase 1/2 study CHAMPION-1 (NCT01677858), which evaluated the safety and efficacy of once-weekly carfilzomib with dexamethasone (Kd) in patients with relapsed or refractory MM. Methods: Patients with relapsed or refractory MM (1-3 prior lines of therapy) were eligible. Patients received carfilzomib as a 30-min IV infusion on days 1, 8, and 15 of 28-day cycles. The phase 1 portion of the study utilized a standard 3+3 dose-escalation scheme. All patients received carfilzomib at 20 mg/m2 on day 1 of cycle 1; patients received 45, 56, 70, or 88 mg/m2 beginning on day 8 of cycle 1 in successive dose-level cohorts until the maximum tolerated dose (MTD) was reached. All patients received dexamethasone 40 mg (IV or oral administration) on days 1, 8, 15, and 22 of cycles 1-8; dexamethasone was omitted on day 22 in cycles ≥ 9. In the phase 2 portion, patients received carfilzomib at the MTD (carfilzomib dose of 20 mg/m2 on cycle 1, day 1; escalating to the MTD for subsequent doses) and dexamethasone at the same dose and schedule. Kd was administered until unacceptable toxicity or disease progression. The primary objective of the phase 1 portion was to determine the MTD of carfilzomib in the Kd regimen; the primary objective of the phase 2 portion was to determine the overall response rate (ORR [≥partial response]). Blood samples were collected for pharmacokinetic and pharmacodynamic analyses. Results: A total of 27 patients were enrolled in phase 1; the MTD of carfilzomib was determined to be 70 mg/m2. Results are presented for all patients treated with Kd at the carfilzomib MTD in both the phase 1b (n=15) and phase 2 (n=89) portions of the study. Among these 104 patients, median patient age was 68.5 years (range, 41-88). Patients received a median of 1 prior line of therapy (range, 1-3); 83% of patients had received prior bortezomib (BTZ), 49% of patients were BTZ-refractory, 27% were LEN-refractory, and 16% were refractory to both BTZ and LEN. Median carfilzomib treatment duration was 7.7 months (range, 0.03-24.2). The ORR was 77% (95% confidence interval [CI]: 68%-85%); the clinical benefit rate (≥minimal response) was 84% (95% CI: 75%-90%). Kaplan-Meier median progression-free survival was 12.6 months (95% CI: 9.0-not estimable). Twelve patients (12%) discontinued treatment due to an adverse event. The most common adverse events of any grade and of grade ≥3 are shown in the Table. Five patients died on study: 1 patient each had cause of death reported as disease progression, acute respiratory distress syndrome, acute respiratory failure, acute kidney injury, and cardiopulmonary arrest. The mean area under the curve and maximum concentration following a 70-mg/m2 carfilzomib dose was 1050 ng×h/mL and 2510 ng/mL, respectively. At 1 hour post dosing of carfilzomib 70 mg/m2, the activity of the predominant chymotrypsin-like proteasome catalytic subunit in peripheral blood mononuclear cells (ie, low molecular mass polypeptide 7) was strongly inhibited (97% inhibition as determined by an enzyme-linked immunosorbent assay [ProCISE]; 93% inhibition as determined by a fluorogenic substrate assay). Conclusions: CHAMPION-1 is the first clinical study to evaluate carfilzomib on a weekly dosing schedule. Once-weekly carfilzomib (70 mg/m2) with dexamethasone demonstrated acceptable safety and tolerability with promising efficacy for patients with relapsed or refractory MM. The dose and schedule of carfilzomib used in the CHAMPION-1 study (20/70 mg/m2) is currently being compared with the regulatory-approved carfilzomib dose and schedule (20/27 mg/m2 administered twice-weekly) in the ongoing, phase 3, superiority study ARROW (NCT02412878).

Abstract Introduction - The nuclear export protein exportin 1, (XPO1) is overexpressed in a wide variety of cancers including multiple myeloma (MM). Selinexor is a first-in-class Selective Inhibitor of Nuclear Export (SINE) compound that binds and inactivates XPO1. Selinexor forces nuclear retention and reactivation of tumor suppressor proteins (TSPs; NF-kB, p53 and FOXO) and reduction of many proto-oncogenes, including MDM2, MYC and Cyclin D. In murine MM models, the combination of selinexor with IMIDs shows synergistic anti-MM activity with good tolerability. Methods - This phase 1b/2 dose escalation study (NCT02343042) using the standard 3+3 design, is designed to determine the tolerability, maximum tolerated dose (MTD), recommended phase 2 dose (RP2D) and preliminary efficacy of selinexor in combination with pomalidomide and dexamethasone (SdP). Patients (pts) with relapsed/refractory MM who received ≥ 2 prior therapies including lenalidomide and a proteasome inhibitor (PI) were enrolled. Selinexor is dose escalated once-weekly (QW, starting at 80 mg) or twice-weekly (BIW, starting at 60 mg), pomalidomide 4 mg PO daily, days 1 -21 and dexamethasone (dex) 40 mg PO weekly in a 28 day cycle. Results - As of 25-Jul-2016, 11 pts (7 male / 4 female) have been enrolled. The median age is 58 years (range, 43 - 76), with a median of 5 (range, 2 - 9) prior treatment regimens. Eight pts had MM refractory to lenalidomide and 7 pts to bortezomib; including 5 pts with MM refractory to both. For the once-weekly selinexor cohort, the 80 mg dose level has been cleared and the 100 mg dose level is on going. For the twice-weekly cohort, the 60 mg dose level has been cleared and 80 mg dose level is on going. Common related grade 1/2 adverse events (AEs) include: nausea 7pts (64%), altered taste 5pts (45%), anorexia 3pts (27%), and diarrhea 3pts (27%). Grade 3/4 AEs include: neutropenia 8pts (73%), thrombocytopenia 4pts (36%), and leukopenia 3pts (27%). There was no febrile neutropenia or bleeding reported to date. No dose limiting toxicities have been observed and MTD has not been reached. Ten pts were evaluable for response including, 1 complete response (CR), 5 partial responses (PR), 3 minor responses (MR), and 1 stable disease (SD). The overall response rate (ORR) is 60% with a clinical benefit rate of 90% (ORR + MR). Responses are rapid in onset, with at least MR achieved by cycle 2 day 1. In lenalidomide and bortezomib refractory patients the ORR was 50%. One pt was deemed not evaluable due to non-compliance with study procedures. Eight pts are still on study, (range <1 - 7+ months) including 4 pts maintaining their response for > 3 months. Conclusions - The all oral combination of selinexor, pomalidomide and low dose dex (SdP) has significant clinical activity (ORR 60%) in pts with heavily pretreated MM. Responses are rapid in onset even with the lower dose cohorts tested thus far, CR can be achieved. No additive toxicities over monotherapy of either pomalidomide or selinexor have been observed. This novel treatment regimen therefore holds promise in addressing the urgent need to induce meaningful and durable responses in patients with IMiD and PI relapsed/refractory MM.

Randomized Phase 2

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.

Background: Multiple myeloma (MM) is common among the elderly, with 35% of patients (pts) diagnosed being aged ≥75 years (y). With increasing overall life expectancy, the incidence and prevalence of newly diagnosed and previously treated MM patients ≥80 y is expected to increase over time. Because elderly pts are often excluded from clinical trials, data focused on their treatment patterns and clinical outcomes are lacking. The Connect® MM Registry (NCT01081028) is a large, US, multicenter, prospective observational cohort study of pts with newly diagnosed MM (NDMM) designed to examine real-world diagnostic patterns, treatment patterns, clinical outcomes, and health-related quality of life patient-reported outcomes. This analysis reviews treatment patterns and outcomes in elderly pts from the Connect MM Registry. Methods: Pts enrolled in the Connect MM registry at 250 community, academic, and government sites were included in this analysis. Eligible pts were adults aged ≥18 y with symptomatic MM diagnosed ≤2 months before enrollment, as defined by International Myeloma Working Group criteria; no exclusion criteria were applied. For this analysis, pts were categorized into 4 age groups: <65, 65 to 74, 75 to 84, and ≥85 y. Pts were followed from time of enrollment to the earliest of disease progression (or death), loss to follow-up, or data cutoff date of February 7, 2019. Descriptive statistics were used for baseline characteristics and treatment regimens. Survival outcomes were analyzed using Cox regression. Time to progression (TTP) analysis excluded causes of death not related to MM. Results: Of 3011 pts enrolled (median age 67 y), 132 (4%) were aged ≥85 y, and 615 (20%) were aged 75-84 y at baseline. More pts aged ≥85 y had poor prognostic factors such as ISS stage III disease and reduced hemoglobin (<10 g/dL or >2 g/dL <LLN) compared with other age groups, although no notable differences between creatinine and calcium levels were observed across age groups (Table). A lower proportion of elderly pts (75-84 and ≥85 y) received triplet regimens as frontline therapy. More elderly pts received a single novel agent, whereas use of 2 novel agents was more common in younger pts (Table). The most common frontline regimens among elderly pts were bortezomib (V) + dexamethasone (D), followed by lenalidomide (R) + D, whereas those among younger pts included RVD, followed by VD and CyBorD (Table). No pt aged ≥85 y, and 4% of pts aged 75-84 y received high-dose chemotherapy and autologous stem cell transplant (vs 61% in the <65 y and 37% in the 65-74 y age group). The most common maintenance therapy was RD in pts ≥85 y (although the use was low) and R alone in other age groups (Table). In the ≥85 y group, 27%, 10%, and 4% of pts entered 2L, 3L, and 4L treatments respectively, vs 43%, 23%, and 13% in the <65 y group. Progression-free survival was significantly shorter in the ≥85 y age group vs the 75-84 y age group (P=0.003), 65-74 y age group (P<0.001), and <65 y age group (P<0.001; Fig.1). TTP was significantly shorter in the ≥85 y group vs the <65 y group (P=0.020); however, TTP was similar among the 65-74 y, 75-84 y, and ≥85 y cohorts (Fig. 2). Overall survival was significantly shorter in the ≥85 y group vs the 75-84 y, 65-74 y, and <65 y groups (all P<0.001; Fig. 3). The mortality rate was lowest (46%) during first-line treatment (1L) in pts aged ≥85 y (mainly attributed to MM progression) and increased in 2L and 3L (47% and 54%, respectively); a similar trend was observed in the younger age groups. The main cause of death was MM progression (29% in the ≥85 y vs 16% in the <65 y group). Other notable causes of death in the ≥85 y group included cardiac failure (5% vs 2% in <65 y group) and pneumonia (5% vs 1% in <65 y group). Conclusions: In this analysis, elderly pts received similar types of frontline and maintenance regimens as younger pts, although proportions varied with decreased use of triplet regimens with age. Considering similarities in TTP across the 65-74 y, 75-84 y, and ≥85 y cohorts, these real-world data support active treatment and aggressive supportive care of elderly symptomatic pts, including with novel agents. Additionally, further clinical studies specific to elderly patients with MM should be explored.

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