Prognostic and Predictive Gene Expression Profiling (GEP) Markers Confirmed in Carfilzomib, Lenalidomide, and Dexamethasone (KRd) Treated Newly Diagnosed Multiple Myeloma (NDMM) Patients (Pts)

Abstract Introduction High rates of complete response (CR) have previously been demonstrated in KRd-treated NDMM pts in a phase 1/2 trial (trial 1; NCT01029054) and a phase 2 trial that combined KRd with autologous stem cell transplant (ASCT) (trial 2; NCT01816971). Here, we report results of extended follow-up from the 2 trials and correlate response and PFS with GEP performed using the MMprofiler GEP assay, which provides results for the SKY92 signature, 7 virtual karyotyping markers (t[4;14], t[11;14], t[14;16]/t[14;20], gain[1q], del[13q], del[17p], H-MM [virtual gain(9q)]), and 3 clusters (MF, MS, CD2). Previously, a combination of 5 markers (SKY92, virtual gain[1q], virtual t[14;16]/t[14;20], MF and CD2 clusters) was identified that predicts improved outcomes when treated with the proteasome inhibitor (PI) bortezomib (van Vliet et al, EHA 2014). We evaluated the SKY92 prognostic signature, virtual karyotyping markers, and this 5-marker PI predictor signature in order to confirm these markers as predictive signatures in the KRd setting. Materials and Methods In the consecutive trials 1 and 2, pts received 4 cycles of KRd induction, followed by extended KRd treatment with deferred ASCT (trial 1; NCT01029054) or ASCT followed by extended KRd treatment (trial 2; NCT01816971). In both trials, pts received single-agent lenalidomide as maintenance after completion of KRd. The MMprofiler GEP assay was performed on RNA from CD138+ purified plasma cells. As depth of response with KRd is associated with improved time-to-event outcomes (Jasielec et al, ASH 2013), data were analyzed for associations between any of the MMprofiler markers and the groups that achieved ≥near CR (nCR) vs <nCR by the end of 4 cycles (Fisher exact test). For progression-free survival (PFS), Kaplan-Meier curves were constructed, median survival estimates were calculated, and the Cox proportional hazards model was used to calculate hazard ratios (HR) and associated p-values. Results Based on a July 1, 2014 cutoff date, 91 pts were enrolled (53 in trial 1; 38 in trial 2). CD138+ RNA was available from 27 pts (16 from trial 1; 11 from pts in trial 2 who completed ≥4 KRd cycles). Pts with H-MM (virtual gain[9q]) were significantly less likely to achieve nCR (p=0.027) (Table 1). None of the other markers were found to have a statistically significant association with response; several markers, however, showed a trend for predictive value at the current sample size. PFS data were available for 16 pts (median follow-up: trial 1, 40 months [mo]; trial 2, 6.7 mo [with no events at the cutoff date]). Two markers were found to be significantly prognostic (Figure 1): SKY92 (5/16 pts [31%]; HR=5.7; p=0.023) and virtual gain (1q) (6/16 pts [38%]; HR=5.5; p=0.017). Virtual t(4;14) was marginally significant (HR=3.7, p=0.055). When considering the 5-marker PI predictor signature, none of the 16 pts were positive for virtual t(14;16)/t(14;20), MF or CD2 clusters. Combining the SKY92 and virtual gain(1q) markers identified a highly significant subgroup of high-risk pts (7/16; 44%) with a median PFS of 26 mo (HR=8.7; p=0.0088; Figure 1). In no-risk pts (9/16), estimated 4-year PFS was 78%. Conclusions Absence of H-MM (virtual gain[9q]) identified pts more likely to achieve ≥nCR by the end of 4 cycles of KRd, with other markers awaiting validation from ongoing enrollment to the KRd + ASCT trial. Based on combined SKY92 high-risk and virtual gain(1q) signatures, the MMprofiler assay detected a highly significant group of high-risk pts with inferior PFS compared to the no-risk group. Despite the inferior outcome, these high-risk pts appeared to have benefited from KRd when compared to historical data of treatment without PIs, suggesting that the 5-marker PI predictor signature (Van Vliet et al, EHA 2014) may also apply to carfilzomib-based treatment. We observed a 4-year PFS rate in no-risk pts in the KRd trials which trended higher than the historical outcome of the PAD arm in the HOVON65/GMMG-HD4 trial (78% vs 34%, respectively), suggesting a benefit for KRd without ASCT in this group of pts compared with other strategies with PIs; further study is needed, however. With ongoing enrollment into the KRd + ASCT trial, the findings reported here will be further validated. Updated results will be presented at the meeting.

Introduction: Patients with high-risk multiple myeloma (HRMM) who have undergone autologous stem cell transplant (ASCT) will inevitably relapse and have a progression free survival (PFS) ranging from 8-14 months (Gaballa et al, American Journal of Hematology, 2016) and 24-39 months while on lenalidomide (Len) maintenance therapy (Jackson et al, The Lancet Oncology, 2019). Unlike in solid tumors, PD-1 blockade has no single agent activity in relapsed and refractory multiple myeloma (MM) patients suggesting that immune stimulating agents, immunomodulatory agents (IMiDs), such as lenalidomide (Len) or pomalidomide (Pom) are necessary in combination with anti-PD-1 blockade to increase depth and duration of response post-ASCT. The Keynote-023 study revealed an overall response rate (ORR) of 76% with the combination of pembrolizumab (Pem), Len and dexamethasone (Dex). Similarly, the Keynote 135 study using the combination of Pem, Pom, and Dex revealed an ORR of 60%. Unfortunately, the phase III studies comparing an IMiD vs Pem with the IMiD upfront at the early relapsed setting were halted because of increased deaths on the Pem arm and a decreased median PFS. With our Phase II study currently on clinical hold by the FDA, we are presenting here the 2-year follow-up of the original patient cohort including some preliminary safety and efficacy data of Pem-Len-Dex in HRMM patients as post-ASCT consolidation (NCT02906332). Methods: Patients with HRMM who have undergone induction therapy followed by single or tandem melphalan-based ASCT were considered eligible 2-6 months post ASCT. HRMM criteria are defined by any of the following: ISS stage 3; del 13q by cytogenetics; FISH with 1q amplification, 1p deletion (del), p53 del, t(4;14), t(14;16), t(14;20), hypodiploidy; or a high-risk gene expression profile score. Patients were excluded if they had progression of disease at time of screening or if there was evidence of organ dysfunction. Patients received Pem 200 mg IV at day 1;Len 25 mg po daily at days 1-14; and Dex 40 mg daily at days 1,8,15 of a 21-day cycle for a total of 2 cycles and then an additional 2 cycles of Pem + Len without Dex at the same dose and frequency. Survival outcomes post-ASCT were measured using the log-rank test. Results: Of 15 patients screened, 12 received at least one dose of therapy and were deemed evaluable. One patient withdrew consent and did not follow up after cycle 2. Baseline characteristics are shown in Table 1. Thirty-three percent were ISS 3, 66.7% had a p53 deletion by FISH, 41.6% received induction Bortezomib-Len-Dex; 33% received induction Carfilzomib-Len-Dex, and the remaining 24.9% received other bortezomib-based induction. Best ORR during the 2 year follow up showed 8 patients (73%) achieving stringent complete remission, 2 patients (18%) showing complete remission and 1 (9%) achieving very good partial remission. Table 2 shows best response to treatment by cycle of therapy. Table 3 shows best response during follow-up visits, which were 3 months apart. Of the 11 patients who completed therapy, 8 had minimal residual disease (MRD) status assessed and among them, 7 were MRD negative by flow cytometry, tested 30 days after the fourth cycle. With a median follow-up of 32.2 months, median PFS was 27.6 months. The PFS rates at 1 year and 2 year are 91.3% and 65.2%, respectively. All patients had adverse events (AEs), AEs were attributed to Pem, Len, or Dex rather than from ASCT. Of the 90 AEs that were reported, 5.6% were grade 3 and 94% were grade 1 or 2 (Table 3). The most common hematologic AE was neutropenia (41.7%), with 3 pts (25%) grade 1 and 2, and 2 pts (16.6%) grade 3. The most common non-hematologic AEs were intermittent constipation (16.6%), diarrhea (16.6%), fatigue (8.3%), and increased ALT (8.3%) and were graded as 1 or 2. Non-hematologic grade 3 AEs occurred in 2 pts and included hypoxia and maculopapular rash. There was 1 serious AE, H. influenza pneumonia requiring inpatient admission, which was not considered to be related to Pem. Conclusions: The combination of Pem, Len, and Dex given to HRMM patients in the post-ASCT consolidation setting is well tolerated. In comparison to historical controls of HRMM patients post-ASCT with a median PFS of 8-14 months, the PFS rates of 91.3% and 65.2% at 1 and 2 year post-ASCT respectively suggest an efficacy signal for the use of Pem, Len, and Dex as post-ASCT consolidation. Larger prospective studies are needed to validate these results.

Secondary Myelofibrosis

Introduction: Primary and secondary myelofibrosis (MF) [i.e. occurring after a prior diagnosis of polycythemia vera [PV] or essential thrombocythemia (ET)] are myeloid malignancies often diagnosed in the 6th and 7th decade of life. In the rare occurrence that younger patients receive this diagnosis, prognostic recommendations are poorly extrapolated and optimal treatment strategies are unclear. Prior studies assessing young MF patients have suggested a more indolent course for this cohort. Here we aim to analyze our experience with young MF patients in terms of genetic makeup, treatment history, and outcomes. Methods: We assessed a database of primary and secondary MF patients who presented to our center between 1/2000 and 6/2019. We identified patients who were 50 years or younger at the time of MF diagnosis. Clinical and genetic features along with treatment history and outcomes were analyzed. Kaplan-Meier method was used for survival analysis. Patients surviving at 240 months after diagnosis were censored at that time. Results: Among 599 MF patients, 63 (11%) were ≤50 at the time of diagnosis. Median age at diagnosis was 43.6 years (yr). Median time from diagnosis to first presentation to our institution was 4.2 months (mo) (range 0-35 yr). Thirty-eight (60%) and 44 (70%) were seen within 1 and 5 years of diagnosis, respectively. Females accounted for 62% (n = 39) of patients. Forty-five (71%) patients had primary MF, 4 (6%) had post-PV MF and 13 (21%) post-ET MF. Median follow-up for the cohort was 94.9 mo. Among 62 patients in whom IPSS at diagnosis could be calculated, 20 (32%) were low, 27 (44%) intermediate-1, 12 (19%) intermediate-2, and 3 (5%) high-risk. JAK2 mutation was detected in 22/60 (37%), CALR in 21/44 (48%), MPL in 0/49 (0%). One patient was triple-negative. Extended targeted gene sequencing was performed in 42/63 patients during their clinical course. Sequencing occurred at a median time of 2.6 yr after diagnosis (range 0-35 yr). Genes most commonly mutated were ASXL1 (12%), TET2 (12%), EZH2 (10%), and DNMT3A (10%). No mutations involving SRSF2, U2AF1, ZRSR2, or SF3B1 were seen. Thirteen patients did not receive active treatment during follow-up. Among those receiving treatment, median time to first treatment was 9.4 mo (range 0-331 mo). The most common initial treatments were erythropoiesis-stimulating agents (ESAs) (14%), hydroxyurea (28%), and ruxolitinib (22%). In total, 29 (46%) received ruxolitinib with median time to ruxolitinib treatment of 27.2 mo. Median duration of ruxolitinib treatment was 44.5 mo. Fourteen patients underwent allogeneic hematopoietic stem cell transplant (AHCT) at a median of 57.4 mo after diagnosis (range 6-123 mo). Transformation to acute myeloid leukemia (AML) occurred in 5 patients at a median time of 99 mo (range 51-178 mo) after diagnosis. Median overall survival (OS) was not reached. Five and 10-year OS estimated at 93% and 77%, respectively. No difference was seen in OS for patients with primary and secondary MF (p = 0.40). Conclusions: Primary and secondary MF are rarely diagnosed in patients ≤ 50 years old. In this cohort, patients are often CALR mutant, have lower-risk disease, and lack splicing mutations. Initial treatment strategies are varied, but favor cytoreductive approaches. The prognosis in these patients is favorable, but high-risk mutations can occur and progression to AML occurs in a minority of patients. AHCT remains a curative option; however, optimal timing for transplant is not clear.

Abstract Abstract 1512 Background: The introduction of tyrosine Kinase Inhibitors (TKI) has significantly improved the outcome of patients (pts) with Ph+ ALL. Dasatinib (Db) is a second generation dual SRC/ABL TKI with greater potency compared to Imatinib in inhibiting BCR/ABL. Aim: To determine the outcome of pts with Ph+ ALL treated with hCVAD + Db. Method: Between 9/06 and 7/09, pts with newly diagnosed Ph+ ALL received Db 50mg oral (PO) twice daily (BID) or 100mg PO daily for the first 14 days of each of 8 cycles of alternating hCVAD, and high dose cytarabine and methotrexate. Pts in complete remission (CR) continued to receive maintenance Db 50mg PO BID or 100mg PO daily, as well as monthly prednisone and vincristine for 2 years, followed by Db indefinitely. From 8/09 protocol was amended and pts received 100mg Db for the first 14 days of cycle #1 and then 70mg daily continuously for the next 7 cycles, as well as 2 doses of rituximab 375 mg/m2 during each of the first 4 cycles. Maintenance was with Db, vincristine and prednisone. Results: Sixty-one pts with newly diagnosed Ph+ ALL have been treated to date. Median age was 56 years (yrs) (range (r), 22–80) and 41 (67%) pts were >50 yrs. The median follow up is 26.1 months (mo) (r, 4–58). Central nervous system (CNS) involvement was noted in 9 (14%) pts at diagnosis. Sixteen (26%) pts had Ph+ alone, 38 (62%) pts had Ph+ with additional abnormalities, and 7 (12%) pts were Ph negative, and BCR/ABL positive. Median white blood cell count (WBC) at diagnosis was 13.4 × 109/L (r: 0.4–658), and 22 (36%) pts had WBC >30 × 109/L at diagnosis. BCR/ABL transcript was identified in 60 (98.3%) pts at diagnosis, including e1a2 in 46 (76%) pts, b2a2 in 10 (17%) pts, b2a2+b3a2 in 2 (3%) pts, b3a2 and e1a3 in 1 (1.6%) pt each. One pt had a variant transcript that was not detectable with the standard primers. The median number of induction and maintenance cycles received were 6 cycles (r: 1–8) and 13.5 cycles (r: 1–24), respectively. Fifty seven (94%) pts achieved CR1 and 1 (1.5%) pts achieved CR with incomplete platelet recovery with first induction cycle of chemotherapy. Three (4.5%) pts died before response assessment could be performed due to infections. Thirty-nine (64%) pts received maintenance, 3 (5%) pts are currently receiving induction and 19 (31%) pts had no maintenance [9 pts received allogeneic stem cell transplant (ASCT) prior to maintenance, 10 pts had progression of disease]. To date, twelve (19%) pts have relapsed and Abl kinase domain mutations were analyzed in 7 pts; mutations were noted in 4 pts. These included T315I in 2 pts, and F359V and V299L in 1 pt each. CNS relapse occurred in 5 pts. Salvage (S1) regimens included [hCVAD + another TKI in 7 pts, single agent TKI in 2 pts, single agent monoclonal antibody in 1 pt, methotrexate, vincristine, asparginase, dexamethasone (MOAD) in 1pt, intrathecal cytarabine/methotrexate plus CNS radiation and Db in 1 pt]. Eight pts achieved CR2, 3 pts were refractory (2 pts with T315I and 1 pt with F359V) and one is still undergoing salvage treatment. Median DFS and OS after S1 were 5.3 mo (r: 0.7–17.3) and 6.7 mo (r: 0.6–24.4), respectively. ASCT was performed in 15 (24%) pts, including 10 pts in CR1 and 5 pts in CR2. Donors were related in 8 (53%) and unrelated in 7 (47%) transplants. Sixteen pts have died 11 (68%) pts from infectious complications, 2 (13%) pts from multi-organ failure, 1 (6%) pt with graft versus host disease, and 2 (13%) pts from unknown causes. Three-year disease free survival (DFS) and overall survival (OS) (n=61) were 49% and 62%, respectively. Conclusion: Db plus hCVAD is an effective regimen with durable responses in pts with newly diagnosed Ph+ ALL. Disclosures: Kantarjian: BMS: Research Funding.

Introduction: The R-MegaCHOEP trial showed that dose-escalation of conventional chemotherapy necessitating autologous stem cell transplantation (ASCT) does not confer a survival benefit for younger patients (pts) with high-risk aggressive B-cell lymphoma in the Rituximab era (Schmitz et al., Lancet Oncology 2012; 13, 1250-1259). To describe efficacy and toxicity over time and document the long-term risks of relapse and secondary malignancy we present the 10-year follow-up of this study. Methods: In the randomized, prospective phase 3 trial R-MegaCHOEP younger pts aged 18-60 years with newly diagnosed, high-risk (aaIPI 2-3) aggressive B-cell lymphoma were assigned to 8 cycles of CHOEP (cyclophosphamide, doxorubcine, vincristine, etoposide, prednisone) or 4 cycles of dose-escalated high-dose therapy (HDT) necessitating repetitive ASCT both combined with Rituximab. Both arms were stratified according to aaIPI, bulky disease, and center. Primary endpoint was event-free survival (EFS). All analyses were calculated for the intention-to-treat population. This follow-up report includes molecular data based on immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) for MYC (IHC: 31/92 positive [40-100%], FISH: 14/103 positive), BCL2 (IHC: 65/89 positive [50-100%], FISH: 23/111 positive) and BCL6 (IHC: 52/86 positive [30-100%], FISH: 34/110 positive) and data on cell of origin (COO) classification according to the Lymph2CX assay (GCB: 53/88; ABC: 24/88; unclassified: 11/88). Results: 130 pts had been assigned to R-CHOEP and 132 to R-MegaCHOEP. DLBCL was the most common lymphoma subtype (~80%). 73% of pts scored an aaIPI of 2 and 27% an aaIPI of 3. 60% of pts had an initial lymphoma bulk and in 40% more than 1 extranodal site was involved. After a median observation time of 111 months, EFS at 10 years was 57% (95% CI 47-67%) in the R-CHOEP vs. 51% in the R-MegaCHOEP arm (42-61%) (hazard ratio 1.3, 95% CI 0.9-1.8, p=0.228), overall survival (OS) after 10 years was 72% (63-81%) vs. 66% (57-76%) respectively (p=0.249). With regard to molecular characterization, we were unable to detect a significant benefit for HDT/ASCT in any subgroup analyzed. In total, 16% of pts (30 pts) relapsed after having achieved a complete remission (CR). 23% of all relapses (7 pts) showed an indolent histology (follicular lymphoma grade 1-3a) and 6 of these pts survived long-term. In contrast, of 23 pts (77%) relapsing with aggressive DLBCL or unknown histology 18 pts died due to lymphoma or related therapy. The majority of relapses occurred during the first 3 years after randomization (median time: 22 months) while after 5 years we detected relapses only in 5 pts (3% of all 190 pts prior CR). 11% of pts were initially progressive (28 pts) among whom 71% (20 pts) died rapidly due to lymphoma. Interestingly, the remaining 29% (8 pts) showed a long-term survival after salvage therapy (+/- ASCT); only 1 pt received allogeneic transplantation. The frequency of secondary malignancies was very similar in both treatment arms (9% vs. 8%) despite the very high dose of etoposide (total 4g/m2)in the R-MegaCHOEP arm. We observed 2 cases of AML and 1 case of MDS per arm. In total 70 pts (28%) have died: 30 pts due to lymphoma (12%), 22 pts therapy-related (11 pts due to salvage therapy) (9%), 8 pts of secondary neoplasia (3%), 5 pts due to concomitant disease (2%) and 5 pts for unknown reasons. Conclusions: This 10-year long-term follow-up of the R-MegaCHOEP trial confirms the very encouraging outcome of young high-risk pts following conventional chemotherapy with R-CHOEP. High-dose therapy did not improve outcome in any subgroup analysis including molecular high-risk groups. Relapse rate was generally low. Pts with aggressive relapse showed a very poor long-term outcome while pts with indolent histology at relapse survived long-term. Secondary malignancies occurred; however, they were rare with no excess leukemias/MDS following treatment with very high doses of etoposide and other cytotoxic agents.

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

Kinesin Spindle Protein

Abstract Abstract 4082 Background: ARRY-520, a novel kinesin spindle protein (KSP) inhibitor, has been studied as a single agent and in combination with dexamethasone, and demonstrated promising clinical activity in patients with bortezomib- and lenalidomide-refractory multiple myeloma (MM). Carfilzomib, a novel irreversible proteasome inhibitor (PI), has also demonstrated single agent activity in relapsed and refractory MM, and recently received regulatory approval for this indication. Preclinical data support the presence of synergy with the combination of a PI and a KSP inhibitor via the latter's ability to down-regulate Mcl-1, supporting our hypothesis that the combination of carfilzomib and ARRY-520 (Car-ARRY) would be highly active in relapsed and/or refractory myeloma. We therefore aimed to combine these two agents for the first time, and here report the initial findings from the phase I dose-escalation in patients with relapsed and/or refractory MM. Methods: The primary objective was to determine the maximum tolerated dose (MTD) and the safety/tolerability of the Car-ARRY combination. Secondary objectives were to determine efficacy as measured by the overall response rate, time to progression, progression free survival and time to next therapy. Patients had to have myeloma that was relapsed and/or refractory, be ineligible for autologous stem cell transplant, bortezomib refractory/intolerant, and prior lenalidomide exposure. ARRY-520 was administered intravenously over 1 hour on days 1, 2, 15 and 16, while carfilzomib was administered intravenously over 30 minutes on days 1, 2, 8, 9, 15 and 16 on a 28 day cycle. All patients received growth factor support with filgrastim. Dose-escalation used a standard 3+3 schema proceeded based on dose-limiting toxicities (DLTs) during cycle 1, with planned escalation of the dose of ARRY-520. Dose level 1 was ARRY-520 0.75 mg/m2, and carfilzomib was dosed at 20 mg/m2 for cycle 1 on days 1 and 2 and all subsequent dose were at 27 mg/m2. Adverse events (AEs) were graded by NCI-CTCAE v4, while responses were assessed by the modified International Uniform Response Criteria. Results: To date, 8 patients have been enrolled in the ongoing dose escalation phase. The median age was 66 (range 47–80), 6/8 were males, and the median number of prior therapies was 4 (range 2–10). 7/8 patients had undergone prior autologous stem cell transplant, and all patients were bortezomib refractory or intolerant. In the first cohort, 3 patients were enrolled and no dole limiting toxicity (DLT) was observed. During the second cohort, ARRY-520 was escalated to 1 mg/m2 with carfilzomib at 20/27 mg/m2, and among the first 3 patients, one patient suffered a DLT in the form of an admission for influenza pneumonia with non-neutropenic fever. Expansion of cohort 2 is currently underway. Among the 6 patients who completed the first cycle of therapy, 5 remain on study. In the first cohort, one patient remains on study with 6 cycles and achieved a near complete remission, 1 patient achieved stable disease, and 1 patient suffered disease progression after first cycle. In the second cohort, all three patients who completed the first cycle have stable disease and remain on trial. In the first 6 toxicity-evaluable patients who have completed one cycle, grade (G) 3 events included one each of pneumonia, diarrhea, and hyperglycemia. There was limited hematologic toxicity with 4/6 patients with G1/2 thrombocytopenia, 3/6 patients with G1/2 anemia, and 1/6 patient with G1/2 neutropenia. Additional G1/2 non-hematologic toxicity included 3/6 patients with diarrhea, 3/6 patients with dyspnea, 3/6 patients with transient elevations in creatinine and 3/6 patients with aspartate aminotransferase elevations. An MTD has not been established and enrollment is ongoing in cohort 2 with carfilzomib at 20/27mg/m2 and ARRY-520 at 1.0 mg/m2. Conclusions: The combination of ARRY-520 and carfilzomib is well tolerated with limited hematologic toxicity and a manageable side effect profile. Notably, in this patient population, with patients who have bortezomib refractory/intolerant myeloma, the combination has demonstrated early signals of activity. Updated safety and efficacy data for all patients will be presented at the meeting.

Hematologic Response

Abstract Abstract 3150 Background: AL is a plasma cell dyscrasia characterized by the pathologic production of monoclonal light chains which misfold, deposit in various organs, including the heart, and can cause early death. High dose melphalan with stem cell transplant (SCT) results in high hematologic response rates and is a standard treatment for eligible patients. Achieving a complete hematologic response (CR) to SCT results in extended event-free and overall survival (OS), up to 8 and 13 years respectively in one large series. (Blood 2011; 118:4346) We have studied the addition of novel agents as consolidation following risk-adapted SCT (RA-SCT) in order to improve hematologic response (HR) rates and therefore outcomes. (Br J Haem 2007;139:224; Amyloid 2010;17:80a) In this report we examine the long-term outcomes of patients who received initial therapy with RA-SCT followed by consolidation for hematologic response less than CR (HR < CR). Methods: We performed a retrospective study to assess the HR rates, incidence of hematologic progression and overall survival (OS) of AL patients enrolled at diagnosis on two consecutive phase II trials using RA-SCT with consolidation for HR < CR (NCT01527032 and NCT00458822). OS was calculated from date of transplant to date of death or last follow up. Median event free survival (EFS) and OS were estimated by the method of Kaplan Meier. Cumulative incidence function was used to estimate the incidence of progression and death. Results: Between 2002 and 2011, 83 patients were enrolled and underwent RA-SCT on these trials and, following RA-SCT, those with HR < CR received consolidation with thalidomide and dexamethasone (TD) in the first and bortezomib and dexamethasone (BD) in the second trial. Thirty-six patients had cardiac involvement (43%) and all patients had free light chain measurements employed to score hematologic response and progression using consensus criteria (Am J Hematol 2005;79:319; Blood 2010;116:1364a). The frequency of CR following SCT was 24% and increased to 48% with post-SCT consolidation. The CR rates increased at 1 year compared to 3 months post-SCT from 21% to 36% with TD and from 28% to 62% with BD. With a median follow up of 5.1 years, the EFS is 4.5 years (95% CI: 2.6 to not reached) and the OS of all patients has not been reached (Figure 1). Sixteen patients died prior to hematologic progression and 26 patients have progressed with a cumulative incidence of hematologic progression of 8%, 18%, and 29% at 1, 2 and 3 years, respectively (Figure 2). Thirty-one percent (8/26) of relapsed patients have not required second-line therapy while among those who have, 78% (14/18) have responded including 44% (8/18) with CR. The median OS following hematologic progression was 5 years (95% CI: 2.6–5.8). Conclusions: Half of the AL patients on initial therapy trials employing RA-SCT and consolidation for HR < CR achieved CR with 36% of pts on the TD and 62% on the BD consolidation trial in CR at 1 year post-SCT respectively. At 3 years post-SCT the cumulative incidence of relapse was 29% and a third of relapsed patients did not require therapy, likely due to the very sensitive serum free light chain assay that detects low level hematologic progression in the absence of organ progression. Almost 80% of patients requiring second-line therapy responded, over half with CR, and median OS after relapse was 5 years. These results indicate that initial therapy with RA-SCT and consolidation is an effective initial treatment strategy for patients with AL in the era of novel agents. With over 5 years of follow up the median OS has not been reached.

Abstract Background: Carfilzomib (Cfz), lenalidomide, and dexamethasone synergize to provide an impressive overall response rate (ORR) in upfront treatment of multiple myeloma (MM) (Jakubowiak et al 2012). The ORR to Cfz+dexamethasone (Cfz-Dex) as first-line therapy is unknown. We hypothesized that sequential treatment with Cfz-dex and BiRD would improve provide similar ORR and improve tolerability. A protocol of Cfz-Dex, consolidation with BiRd (Clarithromycin(Biaxin¨), Lenalidomide/(Revlimid¨), dexamethasone), and lenalidomide maintenance (Len) was conducted to evaluate ORR and safety as induction therapy for MM. Methods: Forty patients (pts) with symptomatic untreated MM were enrolled in a phase 2 study of Car-BiRd. Car-BiRd therapy is: Cfz IV over 30 min 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 dose thereafter and dex 40mg on D1, 8, 15, 22. After the first 26 pts were enrolled, the protocol was amended to increase the Cfz from 45 to 56mg/m2. Echocardiography and spirometry were performed prior to study entry and serum brain natriuretic peptide (BNP) was followed monthly to evaluate for heart or lung toxicity. Cfz-dex was continued until plateau in disease response, defined as unchanged M-protein for 2 cycles. Elective stem cell collection was then performed in transplant eligible pts 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 on D1, 8, 15, 22 of 28-day cycle. BiRd was continued until a 2nd response plateau after which lenalidomide maintenance (Len) at 10mg daily D1-21 of 28 day cycle was continued until disease progression or intolerability. Results: 36 pts completed at least 1 cycle and were evaluable for response. 58% of pts were ISS II/III. High-risk cytogenetics and unfavorable MyPRS score were found in 62% and 21% of pts, respectively. Median study follow-up was 66.2 weeks (range 3.7-114.7). Maximum response to the Cfz-dex, BiRd, and Len is shown in Table 1. Median time to PR was 1 cycle. Median time to maximum response with Cfz-dex, BiRD, and Len was 2, 2, and 4 cycles respectively. At last audit, 8 (22%) pts remain on Cfz-Dex; 21 (58%) reached plateau and received BiRd. Of the pts that received BiRd, 9 (43%) improved categorical response and 19 (90.5%) received Len. Two (11%) pts deepened response to CR while on Len. 97.5% of pts are alive and 82.5% without progression at last follow-up. One pt died after coming off study (withdrew consent) from sepsis during elective autologous stem cell transplant. Pts with high risk cytogenetics had a trend towards a shorter progression free survival (PFS), with median 71.7 weeks vs not reached (NR) (P = 0.058). Similar results were seen with unfavorable MyPRS score with a shorter median PFS at 71.7 weeks vs NR (P = 0.094). 17 pts had stem cell harvest following Cfz-dex. All collected stem cells to support at least two transplants, with median 14.5 x 10^6 (range 7.06-27) CD34/kg in a median of 1 (range 1-2) apheresis session. 18 pts (46.2%) have come off study, 6 (15%) for disease progression (2 during CfzDex , 1 during BiRD, 3 during Len) and 5 pts (12.5%) due to toxicity: 3 pts for renal failure [2 Grade 2, I grade 3, all with renal recovery after discontinuation, all attributable to Cfz]; 1 pt due to Grade III CHF [attributable to Cfz with recovery]; 1 pt with Grade III Thromboembolic [attributable Len]. There was no correlation between pre-study cardiac and lung function, or serial BNP, with toxicities. Seven (17.9%) pts came off study for noncompliance, lost to follow up, investigator discretion, or withdrew consent (Cfz-dex: 4, BiRD: 1, Len: 2). Discussion: This is the first prospective study evaluating induction response to Cfz/Dex in MM. Cfz/Dex is safe and active, with ORR of 91.7% and rate of >=VGPR of 55.6%, despite the majority with a high-risk cytogenetics. Cfz-dex did not hinder stem cell harvest. ORR improved with lenalidomide-based consolidation and maintenance, with CR rate > 50%. Baseline heart/lung function or serial BNP change did not predict emerging toxicities.

Abstract Background: Ibrutinib (ibr), a first-in-class, once-daily Bruton's tyrosine kinase inhibitor, is approved by the US FDA for treatment of patients (pts) with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) including pts with del17p. The phase 1b/2 PCYC-1102 trial showed single-agent efficacy and tolerability in treatment-naïve (TN; O'Brien, Lancet Oncol 2014) and relapsed/refractory (R/R) CLL/SLL (Byrd, N Engl J Med 2013). We report efficacy and safety results of the longest follow-up to date for ibr-treated pts. Methods: Pts received 420 or 840 mg ibr QD until disease progression (PD) or unacceptable toxicity. Overall response rate (ORR) including partial response (PR) with lymphocytosis (PR-L) was assessed using updated iwCLL criteria. Responses were assessed by risk groups: unmutated IGVH, complex karyotype (CK; ≥3 unrelated chromosomal abnormalities by stimulated cytogenetics assessed by a reference lab), and in hierarchical order for del17p, then del11q. In the long-term extension study PCYC-1103, grade ≥3 adverse events (AEs), serious AEs, and AEs requiring dose reduction or discontinuation were collected. Results: Median age of the 132 pts with CLL/SLL (31 TN, 101 R/R) was 68 y (range, 37-84) with 43% ≥70 y. Baseline CK was observed in 41/112 (37%) of pts. Among R/R pts, 34 (34%) had del17p, 35 (35%) del11q, and 79 (78%) unmutated IGVH. R/R pts had a median of 4 prior therapies (range, 1-12). Median time on study was 46 m (range, 0-67) for all-treated pts, 60 m (range, 0-67.4) for TN pts, and 39 m (range, 0-67) for R/R pts. The ORR (per investigator) was 86% (complete response [CR], 14%) for all-treated pts (TN: 84% [CR, 29%], R/R: 86% [CR, 10%]). Median progression-free survival (PFS) was not reached (NR) for TN and 52 m for R/R pts with 60 m estimated PFS rates of 92% and 43%, respectively (Figure 1). In R/R pts, median PFS was 55 m (95% confidence intervals [CI], 31-not estimable [NE]) for pts with del11q, 26 m (95% CI,18-37) for pts with del17p, and NR (95% CI, 40-NE) for pts without del17p, del11q, trisomy 12, or del13q. Median PFS was 33 m (95% CI, 22-NE) and NR for pts with and without CK, and 43 m (95% CI, 32-NE) and 63 m (95% CI, 7-NE) for pts with unmutated and mutated IGVH, respectively(Figure 2). Among R/R pts, median PFS was 63 m (95% CI, 37-NE) for pts with 1-2 prior regimens (n=27, 3 pts with 1 prior therapy) and 59 m (95% CI, 22-NE) and 39 m (95% CI, 26-NE) for pts with 3 and ≥4 prior regimens, respectively. Median duration of response was NR for TN pts and 45 m for R/R pts. Pts estimated to be alive at 60 m were: TN, 92%; all R/R, 57%; R/R del17p, 32%; R/R del 11q, 61%; R/R unmutated IGVH, 55%. Among all treated pts, onset of grade ≥3 treatment-emergent AEs was highest in the first year and decreased during subsequent years. With about 5 years of follow-up, the most frequent grade ≥3 AEs were hypertension (26%), pneumonia (22%), neutropenia (17%), and atrial fibrillation (9%). Study treatment was discontinued due to AEs in 27 pts (20%) and disease progression in 34 pts (26%). Of all treated pts, 38% remain on ibr treatment on study including 65% of TN pts and 30% of R/R pts. Conclusions: Single-agent ibrutinib continues to show durable responses in pts with TN or R/R CLL/SLL including those with del17p, del11q, or unmutated IGVH. With extended treatment, CRs were observed in 29% of TN and 10% of R/R pts, having evolved over time. Ibrutinib provided better PFS outcomes if administered earlier in therapy than in the third-line or beyond. Those without CK experienced more favorable PFS and OS than those with CK. Ibrutinib was well tolerated with the onset of AEs decreasing over time, allowing for extended dosing for 65% of TN and 30% of R/R pts who continue treatment.

Abstract Background: Len maintenance after autoHCT has improved progression-free (PFS) and overall survival (OS). However, the role of additional interventions after autoHCT such as tandem autoHCT or triple therapy consolidation remains to be determined. Methods: This is a phase III clinical trial (NCT#01109004) of transplant-eligible patients (pts) with symptomatic MM <71 years of age within 12 months of initiating therapy and without prior progression who were randomly assigned 1:1:1 to receive melphalan 200mg/m2 autoHCT and 4 cycles of RVD consolidation (lenalidomide 15mg daily days 1-14, dexamethasone 40mg day 1,8 and 15, and bortezomib 1.3mg/m2 days 1,4,8 and 11 every 21 days) (ACM), versus tandem melphalan 200mg/m2 autoHCT (TAM) or versus a single autoHCT (AM). Randomization was stratified by disease risk (cytogenetic abnormalities - del13q by karyotype, del17q, t(4;14), t(14;16), t(14;20) and hypodyploid; or high beta-2 microglobulin) and center. All arms included Len maintenance (at maximum tolerated dose of 5 to 15 mg orally daily until progression) with dose modifications for toxicities. All patients were reviewed centrally for eligibility, response and progression. The primary objective was to compare 38-month PFS of the three arms. The events for PFS included progression, non-protocol anti-myeloma therapy, or death. Comparisons between treatment groups were based on pairwise log-rank tests stratified on disease risk, with significance levels adjusted for the 3 pairwise comparisons and for interim analyses. In calculating the cumulative incidence of progression, the events were progression or non-protocol anti-myeloma therapy, and death was a competing risk. Results: From June 2010 to November 2013, 758 pts (ACM, N=254; TAM, N=247; AM, N=257) aged 20-70 years (median 57y) were enrolled. Of those enrolled, 24% were classified as high risk. Non-compliance rates following the first autoHCT were 12%, 32% and 5% for ACM, TAM and AM, respectively. Median available follow up from randomization was 38 months. Follow-up is continuing through January 2017. 38-month estimated probabilities for PFS were 57% (95% CI: 50-63%), 56% (95% CI: 49-63%) and 52% (95% CI: 45-59%) for ACM, TAM and AM, respectively (ACM vs TAM p=0.75, ACM vs AM p=0.21, TAM vs AM p=0.37). Corresponding probabilities of OS were 86% (95% CI: 80-90%), 82% (95%CI: 76-87%) and 83% (95% CI: 78-88%). Median OS has not been reached. Cumulative incidences of disease progression at 38 months were 42% (95% CI: 36-48%), 42% (95% CI: 35-48%) and 47% (95% CI: 40-54%) for the ACM, TAM and AM arms, respectively. There were 39 cases of second primary malignancy (SPM) reported in 36 participants and the cumulative incidences for first SPM were 6.0% (95% CI: 3.4-9.6%), 5.9% (95% CI: 3.3-9.6%) and 4.0% (95% CI: 1.9-7.2%) for the ACM, TAM, and AM, respectively. Conclusions: The primary results of the largest randomized US transplant trial in MM demonstrated comparable PFS and OS. The addition of RVD consolidation or a second auto-HCT was not superior to a single auto HCT followed by Len maintenance in the upfront treatment of MM. A long term follow-up trial to track outcomes in these patients is ongoing.
