Escalated Dose Bortezomib Once Weekly Combined with Lenalidomide and Dexamethasone (eVRD) Followed by Lenalidomide Maintenance in First Relapse of Multiple Myeloma (MM). the HOVON 86 Phase 2 Trial

Abstract Abstract 1853 Background: Bortezomib (1.3 mg/m2) combined with Lenalidomide (10–25 mg) and Dexamethasone (VRD) is effective in newly diagnosed and relapsed multiple myeloma (MM). Reported data on the effect of these drugs in relapse/refractory MM are available from the APEX and MM-009/MM-010 trials, respectively. These trials, however, were performed in patients with 2–8 prior regimens. Aim: This investigator sponsored two-step phase 2 HOVON trial was designed to evaluate escalated dosages of Bortezomib (B) given once weekly and daily Lenalidomide (L) combined with weekly Dexamethasone (D) (eVRD) followed by Lenalidomide maintenance in an homogenous group of patients with symptomatic MM in first relapse. The goal was to explore the maximum tolerated dose of this combination in order to achieve a durable second remission. Methods: Dose levels were B 1.3 mg/m2, L 10 mg, (level 1); B 1.6 mg/m2, L 10 mg (level 2); B 1.6 mg/m2, L 15 mg (level 3); B 1.6 mg/m2, L 20 mg (level 4). D dose was 20 mg days 1–2, 8–9, 15–16 in all dose levels. Inclusion criteria were symptomatic MM ISS stage 1–3, aged 18–80 in first relapse after initial treatment. The primary endpoint was response (complete response (CR) according to IMWG criteria, very good partial response (VGPR), partial response (PR), together overall response (ORR)) with Progression-free Survival (PFS), overall survival (OS) and toxicity as secondary endpoints. Results: Eighty-one patients were included, i.e. 15 patients in dose levels 1, 2 and 3, followed by 66 in the phase 2 part. This report is based on 12 patients in the dose escalation phase and the first 42 patients in the phase 2 part. Median age was 67 yrs, with ISS stages 1 (56%), 2 (40%) and 3 (5%). 37/54 patients had received HDM followed by stem cell transplant as part of first-line treatment. The MTD was reached at dose level 3 when the maximum of 3 SAEs in 5 patients was observed. After establishment of the MTD, the phase 2 part of the trial was performed with B 1.6 mg/m2 once weekly for 3 weeks, L 20 mg days 1–21 and D 20 mg days 1–2, 8–9, 15–16, for 8 cycles of 28 days followed by L maintenance 10 mg days 1–21 of a 28 days cycle. The median number of cycles was 6 in the dose-escalation phase and 7 cycles in phase 2. 7/12 (58%) patients in the dose-escalation phase and 23/42 (55%) patients in phase 2 started lenalidomide maintenance. Reasons for premature discontinuation of the protocol treatment were toxicity (14%), progression (24%), no response (5%) or other (14%). Polyneuropathy grade 3–4 occurred in 19% with a median time to maximum PNP of 123 days. Hematological toxicity grade 3 and 4 was observed in 29 % of patients In the phase 2 part including 42 patients the ORR was 92 %, ≥VGPR 64% and CR/nCR 30%. Median time to response was 1.1 cycles. At a median follow-up of 13.6 months PFS at 18 months was 52% and OS 76%. Among predetermined risk factors ISS stage, prior HDM/ASCT and achieved response on protocol, depth of response was the only significant factor which was associated with PFS (p<0.001) and OS (p<0.001), Eight patients died from progressive MM (n=4) or other causes (n=4). One second primary malignancy was observed in dose level 3. Conclusions: Escalated VRD followed by Lenalidomide maintenance is effective and feasible in patients with first relapse MM. We will present an updated follow-up at ASH This trial was registered as Eudract nr 2007–002533–37. Unrestricted grants and study drug were provided by Janssen and Celgene.

Abstract Background The outcome of multiple myeloma (MM) patients who are no longer responding to thalidomide, lenalidomide (LEN) and bortezomib (BORT) is very poor, with a median event-free survival of 5 months and median overall survival (OS) of 9 months (Kumar SK et al, Leukemia 2012; 26;149-157). We have previously shown in a small retrospective study that the combination of continuous low dose oral cyclophosphamide (endoxan) and prednisone combined with lenalidomide (REP) had remarkable activity in heavily pretreated LEN-refractory multiple myeloma patients (median 6 lines of previous chemotherapy) (vd Donk et al; Br J Haematol 2010;148(2):335-7). To determine the optimal dose of lenalidomide with continuous cyclophosphamide and prednisone, we initiated a prospective study to evaluate the maximum tolerated dose (MTD) of the REP regimen and to assess its efficacy and safety in LEN-refractory MM patients. Here we report safety and efficacy data from the phase 1 dose-escalation part of the REPEAT-study (NCT01352338). Patients and Methods Patients aged ≥ 18 years with LEN-refractory MM, ECOG-performance status 0-3 and adequate kidney, liver and hematologic function were included. Five dose levels were evaluated using a standard 3+3 design, based on dose-limiting toxicities (DLTs) occurring in cycle 1. Patients received LEN in doses ranging from 10-25 mg/day on days 1-21 of 28-day cycle, while oral cyclophosphamide (50 or 100 mg) and prednisone (20 mg) were given continuously. Therapy was continued until progression. The MTD for the phase 2 part is defined as the highest dose level with 0 or 1 DLT's observed in 6 patients. Results Up till now, 35 patients were enrolled (22 in phase 1 and 13 in phase 2) from August 2011 to June 2013. The phase 2 part is still recruiting and data are not evaluable yet. One patient in phase 1 was excluded because of study violation and is not included in the analysis. The median age of the 21 evaluable patients in phase 1 was 69 years (range 41-73); 76% were male. The median duration of the disease from diagnosis was 41 months (range 18-96), median number of prior therapies was 3 (range 2-6), and 12 patients (57%) had previously received autologous SCT. All patients were LEN-refractory, 19 (90%) had prior BORT treatment, and 16 (76%) had BORT-refractory MM. Fifty-five % of the patients were considered high risk by FISH. At the time of analysis, 16 of 21 patients in phase 1 have discontinued treatment because of disease progression (13), alternative treatment (allo-SCT) (1), or adverse events (2). The MTD was defined as LEN 25 mg days 1-21 of a 28-day cycle, combined with oral cyclophosphamide 50 mg and prednisone 20 mg continuously (dose level 4), based on three patients experiencing a DLT: two developed pneumonia (in dose levels 4 and 5; CTC grade 3), and one patient at dose level 5 experienced CTC grade 3 dyspnea. Neutropenia (18%) and thrombocytopenia (18%) were the most common grade 3 hematological adverse events (AEs), which were managed with growth factor support and/or dose modification. There were no grade 4 hematologic AEs. Grade 3 respiratory tract infections (29%) and grade 2 fatigue (19%) were the most common non-hematological AEs. Venous thromboembolism occurred in 1 patient. Figure 1 shows a waterfall plot of the responses of the patients that participated in the phase 1 part of the study. Overall response rate (≥ PR) was 67% with 6 out of 21 (29%) patients achieving at least VGPR. In addition 2 patients achieved MR (≥ MR: 76%). Median PFS and OS were 6.3 and 15.5 months respectively. Similar results were achieved in the subset of patients with LEN- and BORT-refractory disease. Interestingly, laboratory experiments with purified myeloma cells from these patients suggest synergism between LEN and cyclophosphamide. Conclusions The REP regimen induces high response rates and prolonged PFS and OS in LEN-refractory patients with acceptable toxicity. The MTD is defined as LEN 25 mg days 1-21 of a 28-day cycle, combined with oral cyclophosphamide 50 mg and prednisone 20 mg continuously. Phase 2 is enrolling patients and evaluates efficacy and safety of the REP regimen at the MTD. REP should be considered a valuable salvage option for LEN-refractory MM patients. We will present an updated follow-up at ASH.

Abstract Introduction: Lenalidomide (LEN) plus low-dose dexamethasone (Rd) has been shown to be effective and to have a manageable safety profile in non-Japanese patients (pts) with newly diagnosed multiple myeloma (NDMM) (Rajkumar, Lancet Oncol 2010). Recently, the FIRST trial showed prolonged progression-free survival (PFS) and favorable overall survival (OS) benefits for pts who were administered continuous Rd until progressive disease (PD) vs. the standard of care melphalan-prednisolone-thalidomide (Facon, Blood 2013). In Japan, the combination of melphalan- prednisolone -Velcade®(MPV) is the current standard of care for transplant-ineligible NDMM pts. However, prolonged treatment (Tx) with MPV is associated with increased toxicity including peripheral neuropathy (PN) and bone marrow suppression. Consequently, continuous Tx with MPV may have limited benefits due to toxicity and related Tx discontinuation. MM-025 is a phase 2, multicenter, open-label, registration, single-arm trial. It aimed to evaluate the efficacy and safety of the continuous Rd regimen in Japanese NDMM pts who are transplant-ineligible. Methods: The study enrolled Japanese NDMM pts who were aged ≥ 65 years (yrs), or were not candidates for hematopoietic stem cell transplantation. Pts with an ECOG performance status (PS) score > 2 or with grade ≥ 2 PN were excluded from the study. Tx consisted of LEN (25 mg once daily on days 1–21 of each 28-day cycle) and dexamethasone (40 mg for pts aged ≤ 75 yrs or 20 mg for pts aged > 75 yrs, once daily on days 1, 8, 15, and 22 of each 28-day cycle) until PD or discontinuation. The dose of LEN was adjusted according to baseline renal function: 25 mg/day for pts with normal or mild renal impairment (RI) (creatinine clearance [CrCl] ≥ 60 mL/min); 10 mg/day for moderate RI (CrCl ≥ 30 to < 60 mL/min); and 15 mg every other day for those with severe RI (CrCl < 30 mL/min, not requiring dialysis). Pts who discontinued Tx were followed up every 2 months (mos) for ≥ 5 yrs from the start of Tx. The primary endpoint was overall response rate (ORR; defined as complete response [CR] + very good partial response [VGPR] + partial response [PR]) based on the IMWG criteria. The secondary endpoints included time to response (TTR), duration of response (DOR), PFS, OS, and safety. Statistical analyses included the one-sample binomial test for ORR and Kaplan-Meier analysis for DOR, PFS, and OS. The data cutoff date for this analysis was November 2013. Results: A total of 26 pts were enrolled. Of these, 46.2% of pts (n = 12) were aged > 75 yrs, 50.0% (n = 13) were male, 19.2% (n = 5) had ISS stage III disease, 23.1% (n = 6) had an ECOG PS score of 2, and 7.7% (n = 2) had severe RI (CrCl < 30 mL/min). With a median follow-up of 7.4 mos, the median Tx duration was 6.4 mos. The ORR was 83.3%, including VGPRs (12.5%) (n=3) and PRs (70.8%) (n=17). The median TTR was 2.0 mos. Due to the short follow-up DOR, PFS, and OS were not reached at data cutoff. The most common grade 3–4 adverse events (AEs; reported in > 10% of pts) were anemia (19.2%), neutropenia (15.4%), and rash (11.5%). The most frequently reported AEs (≥ 20% incidence) were rash, constipation, anemia, nasopharyngitis, and insomnia. A total of 8 pts (30.8%) discontinued the study: 4 due to AEs, 3 through the investigator’s decision and 1 due to protocol deviation. No deaths, thromboembolic events, or second primary malignancies were reported. Conclusion: Continuous Rd was effective and well tolerated by Japanese transplant-ineligible NDMM pts. These findings are consistent with those reported in the FIRST trial (Facon, Blood 2013) and support the use of the Rd combination regimen as a first-line Tx for this pt group.

Increased Risk

Background: The current commonly used regimens in newly diagnosed multiple myeloma (NDMM) utilize steroids (dexamethasone or prednisone) in various combinations: bortezomib, lenalidomide and dexamethasone (VRd), bortezomib, thalidomide and dexamethasone (VTd), daratumumab, lenalidomide and dexamethasone (DRd) and daratumumab, bortezomib, melphalan and prednisone (DVMP). However, steroid therapy may be associated with various adverse effects, including, but not limited to mood changes, insomnia, hypertension, hyperglycemia, osteoporosis, adrenal suppression, muscle weakness, and increased risk of opportunistic infections. A recent trial demonstrated improved tolerability of a regimen (Rd-R) involving an abbreviated course of dexamethasone, without compromising the efficacy in patients with intermediate-fit NDMM (Lorocca A., et al., ASH 2018). We designed a phase 2 clinical trial to examine the safety and efficacy of daratumumab, an anti-CD38 monoclonal antibody in combination with an all-oral regimen of ixazomib, a proteasome inhibitor, lenalidomide, an immunomodulatory drug, and modified dose dexamethasone (IRd). Patients and Methods: NDMM patients with measurable disease and adequate organ function were enrolled, irrespective of their transplant eligibility. The primary objective was to determine the rate of complete response (CR) to daratumumab-IRd. Treatment consisted of daratumumab, 16 mg/kg, weekly for two cycles, every other week during cycles 3-6 and then every 4 weeks, ixazomib, 4 mg days 1, 8, 15, lenalidomide, 25 mg days 1-21, and dexamethasone upto 40 mg intravenously weekly for no more than two cycles, followed by use only as a prophylactic premedication for daratumumab-associated infusion reactions. Myeloma risk stratification was assessed by cytoplasmic immunoglobulin fluorescence in-situ hybridization (cIg FISH) analysis. Results: Overall, 40 patients were accrued, with data available on all patients for analysis at the cutoff date of July 19, 2019. The median age at enrollment was 64.5 (33-81) years; 37.5% were female. Eight (20%) patients were high risk by FISH. The median number of cycles was 6 (2-11) and the median follow up was 6.1 (2-11.7) months. Among 40 patients who had received at least 2 cycles of therapy, responses were attained rapidly; at the end of cycle 2, 88% patients achieved at least a partial response and 33% at least a very good partial response (VGPR) that improved to 52% at the end of 4 cycles among 29 patients who had completed at least 4 cycles. The overall best confirmed response rate among all 40 patients (Figure 1) was 95%, including 10% stringent CR, 5% CR and 23% near CR (13% VGPR excluding nCR). Stem cell collection was completed in 17 patients so far, all of whom required filgrastim and plerixafor. The median CD34+ cell count was 7.7 (range 2.9-11.6) million/kg . All patients were alive and 39 (97.5%) patients were progression-free at last follow up. Four (10%) patients proceeded to autologous stem cell transplantation off study, per patient and/or investigator discretion (1 in CR, 2 in PR, 1 with progressive disease). Overall, 224 cycles have been administered across the study, with dose reduction/ hold required in a subset of patients; ixazomib (10%), lenalidomide (20%), daratumumab (0%) and dexamethasone (13%); the most frequent reasons for dose adjustment were skin rash and hematologic toxicities. A grade 3 or higher adverse event, at least possibly attributed to the study drugs, was observed in 40% of patients; hematologic in 30% (lymphopenia 25%, neutropenia 15%, thrombocytopenia 5% and anemia 2.5%) and non-hematologic in 18% of patients (hyperglycemia 8%, diarrhea 5%, infections 5%, ileus 2.5%, maculopapular rash 2.5%, and fatigue 2.5%). Updated results with additional 6 months of follow up and minimal residual disease assessment related data will be presented at the meeting. Conclusion: Our early results suggest that the combination of daratumumab, ixazomib, lenalidomide and modified dose dexamethasone is well-tolerated, with excellent activity, and does not adversely impact stem-cell mobilization in patients with NDMM.

Salvage options for children with relapsed ALL remain sub-optimal, particularly for T-cell ALL patients, and relapse remains the leading cause of death. Achieving complete remission (CR) after relapse is the first critical step to cure. Combining the proteasome inhibitor (PI) bortezomib with chemotherapy has previously shown promising results in achieving CR in pediatric phase 2 studies in ALL (Messinger 2012, Horton 2013, Bertaina 2017). In this ongoing dose-escalation phase 1 study, the second generation PI carfilzomib was combined with chemotherapy in children with relapsed ALL. Subjects received one 4-week cycle of induction chemotherapy with either UKALLR3 (dexamethasone, mitoxantrone, methotrexate, PEG-asparaginase, vincristine) or VXLD (vincristine, dexamethasone, PEG-asparaginase, daunorubicin) plus carfilzomib administered intravenously on days 1, 2, 8, 9, 15, and 16. The primary endpoint was dose limiting toxicities (DLTs) occurring during induction (grade 4 neutropenia or thrombocytopenia extending past day 45 or grade 4 non-hematological toxicity). Efficacy endpoints included CR (with or without hematological recovery) based on bone marrow (BM) and LP on day 29 of induction and consolidation. Subjects < 21 years of age and diagnosed with first early BM relapse (<36 months from diagnosis), multiply relapsed ALL, or primary induction failure were eligible; subjects with T-cell disease with any BM relapse were eligible. Subjects achieving ≥ stable disease could receive a cycle of modified BFM consolidation therapy (6-MP, cyclophosphamide, cytarabine, PEG-asparaginase, IT chemotherapy) plus carfilzomib at the same dose level and schedule given in induction therapy. Dose escalation was based on an evaluation of DLT's using a Bayesian logistic regression model. Ten subjects with B (n=9) or T- (n=1) cell ALL were treated with UKALLR3 at 2 carfilzomib dose levels (20 or 27 mg/m2, 5 subjects each). Among DLT-evaluable subjects, 3 DLTs (meningoencephalitis, hemolytic uremic syndrome and neutropenia) were observed, 2 at 27 and 1 at 20 mg/m2 dose levels with an MTD of 27 mg/m2. The UKALLR3 regimen was considered too toxic by the protocol steering committee and was replaced with VXLD in January 2016. The VXLD cohort started at 27 mg/m2 and is currently in the 56 mg/m2 dose level. Fifteen subjects (7 B-cell and 8 T-cell) were treated with VXLD at carfilzomib dose levels of 27 (n=3), 36 (n=7), 45 (n=4), and 56 (n=1) mg/m2. One DLT of posterior reversible encephalopathy syndrome (PRES) occurred in the 36 mg/m2 cohort, with no further DLTs identified after expansion to 7 subjects. Table 2 lists the patient characteristics of the 15 subjects in the VXLD cohort. Grade 3-4 hematological AEs were nearly universal for both UKALLR3 and VXLD. Non-hematological > Grade 3 AE's of note are listed in Table 1. PRES occurred in 2 subjects in the VXLD cohort (both with prior allogeneic SCT) and rapidly reversed in both cases. Re-challenge with carfilzomib in one case was tolerated without PRES recurrence. Serious AE's (SAE) were reported in 50% and 56% of subjects receiving carfilzomib in combination with UKALLR3 or VXLD, respectively, with the most common SAE's among all subjects being sepsis (16%), pancreatitis and PRES (8% each). In the UKALLR3 cohort, 60% of subjects (n=6) achieved a remission, however only 30% proceeded to consolidation. In the VXLD cohort, 53% of evaluable subjects (n=8) achieved remission and 13% were non-evaluable due to hypocellular BM at day 29 of induction. All responding subjects recovered hematological counts by day 42 without evidence of progression. Eight subjects (53%) proceeded to consolidation, including 2 subjects with non-evaluable BM results and 1 with 8% BM blasts after induction. All subjects entering consolidation were in remission on day 29 post-consolidation. The overall remission rate with VXLD-carfilzomib was 67% at the end of consolidation. Detailed response data are listed in Table 3. Carfilzomib in combination with VXLD chemotherapy was tolerable in a predominantly T-cell ALL population, very early or post stem cell transplant relapse. Efficacy is promising in this small cohort of patients with carfilzomib dose escalation continuing. Disclosures Burke: Amgen, Inc.: Consultancy, Speakers Bureau.

Abstract Background: CD38 is a type II transmembrane glycoprotein that is expressed at high levels on multiple myeloma cells. MOR202 is a HuCAL-derived, human, IgG1 anti-CD38 monoclonal antibody showing effective antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-dependent cell-mediated phagocytosis (ADCP), and high activity in preclinical models of multiple myeloma. Patients and Methods: Here we reportinterimsafety and preliminary efficacy data from this ongoing, multicenter, MOR202 dose-escalation, phase I/IIa study in patients with relapsed or refractory disease who had failed ≥2 prior therapies for multiple myeloma, including an immunomodulatory drug and a proteasome inhibitor. The objectives are to evaluate the safety, maximum tolerated dose (MTD)/recommended dose and preliminary efficacy of MOR202 when administered as monotherapy or in combination with dexamethasone (DEX); pomalidomide (POM) + DEX; and lenalidomide (LEN) + DEX. Patients received MOR202 as a 2-hour intravenous infusion every 2 weeks (q2w; dose levels 0.01-16 mg/kg), 4 mg/kg weekly (q1w) and 4, 8 and 16 mg/kg q1w + DEX. The combination cohorts receiving MOR202 8 mg/kg with LEN + DEX and POM + DEX have been opened, and the 16 mg/kg q1w with LEN + DEX or POM + DEX, as well as confirmation cohorts, are planned. Results: As of 26 June 2015, 44 patients have been treated; 31 and 13 patients in the q2w and q1w dose levels, respectively. Median age was 69 years (range 44-80); median number of prior therapy lines was 4 (2-11). The MTD has not been reached. The most common treatment-emergent adverse events (TEAEs) at any grade were anemia (15 patients, 34%), fatigue (14 patients, 32%), infusion-related reactions (IRRs) and leukopenia (13 patients, 30% each), lymphopenia and nausea (11 patients, 25% each). Grade ≥3 TEAEs were reported for 28 patients (64%); the most common included lymphopenia (8 patients, 18%), leukopenia (5 patients, 11%) and hypertension (4 patients, 9%). IRRs arose mainly during the first infusion; all were grade 1-2 except for one patient (grade 3); no IRRs occurred in patients receiving MOR202 in combination with DEX. Infections were commonly reported (26 patients, 59%) but in the majority of the cases were not considered to be treatment-related. There have been no treatment-related deaths. Pharmacokinetic (PK) data demonstrated a significant target-mediated drug disposition effect for most patients treated q2w. By contrast, patients treated q1w (4 or 8 mg/kg) showed constant or slightly accumulating MOR202 trough levels, suggesting the potential for full target occupancy at 16 mg/kg. Long-lasting tumor control has already been observed in early monotherapy cohorts, including one partial response and one very good partial response in the weekly cohorts; efficacy analyses are ongoing. First data from the dose escalation of the weekly cohorts with DEX and the combination cohorts with LEN + DEX and POM + DEX will be presented. Conclusions: At doses up to 16 mg/kg,MOR202 was safe and well tolerated. Encouraging preliminary activity of MOR202 was observed, especially with the weekly regimen. PK data show the potential for full target occupancy in patients receiving MOR202 16 mg/kg q1w. This dosing schedule of MOR202 is currently being tested in combination with DEX, LEN + DEX, and POM + DEX.

Abstract Introduction and background The treatment of patients with Multiple Myeloma (MM) with relapse or progressive disease after bortezomib, lenalidomide and high-dose therapy represents an important challenge. In the EMN02 collaborative trial newly diagnosed patients with symptomatic MM were randomized to receive VCD induction followed by HDM/ASCT or VMP, followed by a second randomization for VRD consolidation or no consolidation, followed by lenalidomide maintenance until progression (Cavo et al, ASH2017, abstract #397; Sonneveld et al, EHA2018, abstract #108). The present Phase 2 trial was designed for patients with refractory disease or first progression after inclusion in EMN02 in order to evaluate a salvage treatment with next generation proteasome inhibition and IMId, i.e., Carfilzomib, Pomalidomide and Dexamethasone. The primary endpoints were response and progression-free survival (PFS). This trial is registered at www.trialregister.nl as NTR5349 and EudraCT 2013-003265-34. Methods Patients who were included received four 28-days re-induction cycles of KPd, i.e. Carfilzomib (20/36mg/m2, days 1,2,8,9,15,16) with Pomalidomide (4 mg days 1-21) and Dexamethasone (20mg days 1,2,8,9,15,16). In patients who had not previously received HDM/ASCT, HDM(200 mg/m2) was administered followed by autologous stem cell transplantation with stem cells harvested during after induction therapy in the EMN02 trial. Consolidation consisted of 4 additional cycles of KPd, identical to the induction cycles. Patients with stable disease or better received Pomalidomide 4mg w/o Dexamethasone in 28 days cycles until progression. Results At the time of this first planned interim analysis 82 patients were registered and this analysis was performed in the first 60 patients. 48% were randomized prior HDM/ASCT and 42% VMP, and 10% were not randomized. Prior best responses in the EMN02 trial were 35% CR/sCR , 75% ≥VGPR, 97% ≥PR. The median follow-up from inclusion in EMN02 was 43 months (range 21 - 62 months). In 44 patients cytogenetic risk were known, 15 (34%) of them had high-risk FISH (del17p, t(14;16) or t(4;14)). 57 fifty-seven (95%) of patients had progressed during lenalidomide maintenance, 3 patient's data are not yet available. In the present trial 38 (63%) of patients achieved normal completion of treatment according to of the protocol. Twenty patients received their first HDM plus ASCT. Median time on therapy was 14 months. Full dose re-induction treatment according to protocol could be administered in 68% (for Carfilzomib) and 64% (for Pomalidomide) of patients respectively, while for consolidation this was 62% for both Carfilzomib and Best response on protocol was 31% CR/sCR, 65% ≥VGPR, 87% ≥PR, respectively, with no difference according to response on initial treatments. Median time to response (≥PR) was 2 months. At a median follow-up of 16.3 months (range 3 - 32 months) median PFS was 18 months with better outcome in standard risk cytogenetics (HR=0.27 (0.09, 0.83) 95% CIs vs NR) and in patients with prior VMP treatment (HR=0.49 (0.21, 1.16) 95% CIs vs NR). 48 (80%) of patients are alive and in follow-up. KPd-emerging non-hematologic grade 3 and 4 adverse events included cardiovascular (5%), respiratory (5%), infections (20%) and neuropathy (3%). There were 3 fatal SAEs not related to progression (1 patient cardiac failure, 2 patients pneumonia). KPd-emerging hematological toxicity grade 3 and 4 occurred in 30% of patients. Discussion This Phase 2 clinical trial demonstrates that KPd is a feasible, effective and safe triple drug regimen in RRMM patients who have been previously treated and/or are refractory to bortezomib and refractory to lenalidomide. A 87% overall response rate including 31% CR/sCR is clinically relevant in this population. Since median OS has not been reached, longer follow-up is needed.

Abstract Background Immunomodulatory drugs (IMiD), such as thalidomide and lenalidomide (LEN) and its newest derivative pomalidomide (POM), have shown great promise for the treatment of multiple myeloma (MM) patients (pts). POM has in vitro anti-MM potency and has shown efficacy for the treatment of relapsed/refractory (RR) MM pts. POM with dexamethasone (DEX) induces responses even for MM pts who are refractory to bortezomib (BORT) and LEN (Richardson et al, 2012). Pegylated liposomal doxorubicin (PLD) with BORT is FDA-approved for the treatment of MM pts who have received one prior therapy not containing BORT. The combination of PLD and LEN or thalidomide has shown efficacy for both RR and frontline MM pts (Offidani et al, 2006; 2007). We have also demonstrated that both the efficacy and tolerability of LEN in combination with DEX, PLD and BORT (DVD-R) may be improved by changing the doses and schedules of these drugs (Berenson et al, 2012). Based on these results, we hypothesized that the combination of POM, DEX and PLD would be effective for the treatment of RRMM pts. Thus, we conducted the first study investigating the safety and efficacy of POM in combination with intravenous (IV) DEX and PLD as a phase 1/2 trial using a modified dose, schedule and longer 28-day cycles for pts with RRMM. Methods The phase 1 portion enrolled MM pts w/ progressive disease whereas those enrolled in phase 2 also had to be refractory to LEN (single-agent or in combination), as demonstrated by progressive disease while receiving their last LEN-containing regimen or relapsed within 8 weeks of their last dose of this IMiD. Pts who have previously received POM treatment were ineligible. In the phase 1 portion, POM was administered at 2, 3 or 4 mg daily in three cohorts on days 1-21 of a 28-day cycle and DEX (40 mg) and PLD (5 mg/m2) were fixed and given intravenously on days 1, 4, 8, and 11. Results As of June 20th, 2014, 48 pts were enrolled in the trial and a total of 47 pts had received study drug. Pts had received a median of 4 prior treatments (range 1-18), with a median of 2 prior IMiD-containing regimens (range, 0-8). Fifty-three percent of the pts had received a prior PLD-containing regimen and 21% had received a prior IMiD and PLD combination treatment. Among all enrolled pts, 40 pts discontinued treatment and seven remain active. Pts completed a median of 3 cycles (range: 1-8), with a median follow-up time of 5.4 months (range: 0-22). During the phase 1 portion of the trial, the maximum tolerated dose (MTD) of POM was established at 4 mg. Enrollment of pts into the phase 2 portion of the trial began at the MTD. However, neutropenia ≥ grade 3 was observed at this dose in 10/17 (58.8%) phase 2 pts; and, as a result, the protocol was amended so that the MTD was lowered to 3 mg for all pts subsequently enrolled. Among the 36 pts enrolled in phase 2, 78% percent were refractory to LEN and steroids with or without other agents and 47% had previously received PLD. A median of 2 cycles (range, 1 to 8) were administered among the pts enrolled in phase 2. Thirty-five pts were evaluable for response as one pt was active but had not yet had any post-baseline disease assessments. Among all pts enrolled in phase 2, the overall response rate (ORR) and clinical benefit rate (CBR) were 29% and 49%, respectively, with 6 pts (17%) showing stable disease and 12 pts (34%) demonstrating progressive disease. For all pts enrolled in phase 2, the median follow-up time was 4.7 months (range 0-12) and the median PFS was 5.3 months. ORR and CBR for pts in the phase 2 were higher among pts receiving POM at 3 mg (32% and 58%, respectively) than among pts receiving POM at 4 mg (25% and 37%, respectively). Pts receiving the 4 mg dose of POM experienced more toxicities resulting in discontinuations, which likely explains the lower ORR and CBR observed among pts receiving this POM dose. Common ≥ grade 3 adverse events observed throughout the trial were neutropenia (21 pts; 44.7%), lymphopenia (10 pts; 21.3%), and hyponatremia (4 pts; 8.5%). One pt died of grade 5 sepsis. Conclusions This phase 1/2 trial is the first evaluating POM with PLD and DEX and demonstrates that the combination of POM at 3 mg, PLD and DEX using a modified 28-day cycle schedule is safe and effective for the treatment of MM pts refractory to LEN.

Background Pomalidomide is an immunomodulatory drug that has been approved for the treatment of relapse refractory myeloma. A previous small randomized phase 2 study in the United States showed that combination of Pomalidomide, cyclophosphamide and dexamethasone induce a greater response rate than pomalidomide and dexamethasone1. In our prior study, AMN0012, we should that in patients with sub-optimal response to pomalidomide and dexamethasone, the addition of cyclophosphamide can increase response resulting in improvement of progression free survival. In the current study, we seek to randomize Asian patients with RRMM between PCD and PD to confirm the benefit of PCD. Method We conducted a prospective randomized trial of pomalidomide (4mg daily for 21 days followed by 7 days rest) plus dexamethasone 40mg once weekly for 4 weeks with or without cyclophosphamide (400mg once a week) in patients with relapse and refractory myeloma that has to be refractory to lenalidomide and has prior exposure to proteasome inhibitors. Each cycle is 4 weeks. Patients from Singapore, Japan and Korea (NCT03143049) were included in this Asian Myeloma Network trial. The trial was started in Sep 2017 and is still ongoing. To date, 53 patients have been recruited so far. This interim report presents data available up till the data cut-off date of 24 June 2020. Results Forty-six patients have available base line information and safety data and is included in this interim analysis. 50% of patients are male and median age of the cohort is 68 years old. 39% and 28% of patients are International Stage System (ISS) stage 2 and 3 respectively. 20% of patients have abnormal creatinine clearance. Median prior line of treatment is 3. All patients are refractory to lenalidomide and 96% have prior exposure to bortezomib. In addition, 12 patients (26%) and 5 (11%) have been treated with Carfilzomib and Ixazomib respectively. 15 (33%) patients had prior high dose melphalan and autologous stem cell transplant. 20 (44%) patients required dose reduction of pomalidomide, cyclophosphamide or dexamethasone. 89% of patients experience adverse events (AEs) of any grade. Of the 297 episodes of AEs, 43% are grade 3 or higher, with 50% of these episodes related to the study drugs. 57% of patients experienced serious AEs (SAEs) of any grade. Of the 74 episodes of SAE, 89% are grade 3 or higher, with 49% of these episodes related to the study drugs. Almost all of these events are related to cytopenias and infections. 20 (44%) of the patients develop grade 3 neutropenic fever and 9 (20%) patients have grade 3 or higher pneumonia. Only 1 patient experienced grade 3 peripheral neuropathy, 1 patient develop grade 3 pulmonary embolism, 1 patient developed grade 3 venous thromboembolism, and 1 patient experienced grade 3 renal impairment. At a median follow-up of 10.9 months, 9 of the 46 patients have died, and 21 have progressed. Three patients withdrew due to toxicity. While the overall response of the study population is not part of this interim analysis, we assessed the response of patients from the National University Cancer Institute, Singapore which has the highest number of patients recruited to get an idea of the therapeutic efficacy. Of the 14 patients recruited at NCIS, 1 patient achieved CR, 3 VGPR, 7 PR, producing a response rate of 79%. Conclusion In this interim analysis of a prospective randomized study of pomalidomide and dexamethasone with or without cyclophosphamide in Asian patients, we demonstrated the feasibility and efficacy of this combination. Longer follow-up and final analysis of the study will be needed to ascertain the therapeutic advantage of PCD over PD in relapse and refractory myeloma that is refractory to lenalidomide.

Abstract Background: The initial report of the CREST phase 2 study (Br J Haematol2004;127:165–72) demonstrated the substantial activity of bortezomib (VELCADE®, Vc) at two different dose levels in patients with relapsed or refractory multiple myeloma (MM). Here, we provide an updated analysis of overall survival (OS) after prolonged follow-up (median >5 years). Methods: 54 patients were enrolled to receive Vc 1.0 mg/m2 (n=28) or 1.3 mg/m2 (n=26) on days 1, 4, 8, and 11 of a 21-day cycle, for up to 8 cycles. Dexamethasone (dex) 20 mg on the day of and day after each Vc dose was added for 16 (57%) patients in the 1.0 mg/m2 group and 12 (46%) patients in the 1.3 mg/m2 group, upon suboptimal response to Vc alone. A total of 17 (31%) patients continued to receive Vc ± dex in an extension study, 12 (43%) from the 1.0 mg/m2 and 5 (19%) from the 1.3 mg/m2 groups. Patients received a median of 3 (range, 1–7) prior regimens. Median time from diagnosis to first Vc dose was 2 years. In the 1.0 and 1.3 mg/m2 groups, respectively, mean age was 64 vs 60 years, 50% vs 35% of patients were male, 54% vs 65% had IgG MM, 58% vs 48% had β2-microglobulin ≥4 mg/L, and 29% vs 48% had abnormal cytogenetics. Response rate (CR+PR, EBMT criteria) to Vc alone was 30% vs 38%, and to Vc ± dex was 37% vs 50% in the 1.0 and 1.3 mg/m2 groups. OS from first dose of Vc in each dose group was analyzed using the Kaplan-Meier method. Results: Median OS in the 1.0 and 1.3 mg/m2 groups was 26.8 months and 60.0 months, after median follow-up of 61 and 65 months, respectively (Figure). In the 1.0 mg/m2 group, 21 (75%) patients have died; the 1- and 2-year OS rates were 82% and 54%, respectively. In the 1.3 mg/m2 group, only 14/26 (54%) patients have died; 1- and 2-year OS rates were 81% and 69%, respectively. Conclusions: Vc ± dex was active in relapsed or refractory MM at both the 1.0 mg/m2 and 1.3 mg/m2 dose levels and was associated with notable OS, particularly in patients treated with the approved Vc dose of 1.3 mg/m2. The difference in OS between dose groups suggests that the higher dose of Vc is more active. Figure. Kaplan-Meier analyses of OS in patients who received Vc 1.0 mg/m2 (n=28) or 1.3 mg/m2 (n=26).

Abstract Abstract 1874 Poster Board I-899 Lenalidomide (Revlimid®) and dexamethasone is an effective regimen in relapsed/refractory multiple myeloma (MM) patients (pts), with an overall response rate of 60.6% and median time to progression (TTP) of 13.4 months (Dimopoulos MA, et al, Leukemia 2009 Jul 23 [Epub ahead of print]). Oral cyclophosphamide and prednisone is an older regimen with excellent patient tolerance, and we sought to enhance the efficacy of lenalidomide by adding oral cyclophosphamide and prednisone in this phase I-II trial. The CPR regimen consisted of cyclophosphamide on days 1, 8 and 15; lenalidomide on days 1–21; and prednisone 100 mg every other day in a 28 day cycle. ASA 81 mg/day was given to all pts as DVT prophylaxis. Three dose levels were evaluated using a 3 by 3 dose escalation design. Between 11/2007–07/2009, 31 pts with relapsed/refractory MM who had not previously received lenalidomide were entered onto study. Median age was 61 (40–78) years and 61% were male. Immunoglobulin subtype was IgG in 19 pts (61%), IgA in 8 pts (26%) and light chain only in 4 pts (13%). Median number of prior regimens was 2 (1–5) and 28 pts had undergone previous ASCT, including double transplants in 6 pts. Prior therapy included thalidomide in 9 (29%) and bortezomib in 15 (48%). FISH cytogenetics were available in 13 pts; one had 13q deletion but none had t(4;14) or p53 deletion. At the time of protocol entry, median β 2-microglobulin level was 246 (92–767) nm/L, albumin 39 (34–48) g/L, creatinine 83 (50–126) μmol/L, platelet count 230 (75–337) × 109/L and ANC 2.5 (1.1–6.1) x 109/L. Protocol treatment is summarized in Table 1. Dose limiting toxicity was not observed during cycle 1 at any dose level. Grade 3–4 toxicities included thrombocytopenia in 5 pts (16%) and neutropenia in 9 pts (29%). These were managed with dose reduction and/or growth factor support. Four episodes of febrile neutropenia occurred. Other grade 3–4 non-hematologic toxicities included abdominal pain/bacteremia in 1 pt in cohort 1; hypokalemia in 1 pt in cohort 2; and DVT in 2 pts, dizziness in 2 pts and fatigue in 1 pt in cohort 3. Using the International uniform response criteria (Durie BG, et al, Leukemia 2006; 20:1467–1473), the best response was documented at a median of 6 (1–5) cycles and included the following: dose level 1 (1 CR, 2 PR); dose level 2 (1 VGPR, 2 PR); dose level 3 (5 CR, 9 VGPR, 9 PR, 1 MR and 1 stable disease). At a median follow-up (F/U) of 12 (8–21) months, 20 pts remain on study, 2 have withdrawn and 9 pts have progressed at a median of 9 (4–13) months; only 1 one has died (due to MM). We conclude: 1) the combination of full doses of the agents in CPR can be given in a 28 day cycle with minimal toxicity; 2) the overall response rate (CR + VGPR + PR) in 31 pts to date is 93%; 3) at a median F/U of 1 year, only 9 pts (29%) have progressed; 4) longer follow-up is required to assess the TTP and survival of the CPR regimen.
