Abstract Abstract 618 Introduction: Steroids have been an important component of multiple myeloma (MM) therapeutics. High doses steroids as used in MM are associated with significant toxicity and morbidity. Development of steroid independent or steroid-lite regimens remains an important area of investigation in MM. Orlowski et al combined Doxil (D) with bortezomib (V) and showed enhanced anti-myeloma activity. In a phase II study in relapsed refractory MM patients, we observed further improvement in clinical efficacy with addition of thalidomide (T) to VD combination (VDT regimen). Encouraged by high response rates of this steroid sparing novel combination we investigated VDT regimen in treatment naïve MM patients. Final results of this phase II trial are reported here. Methods: Patients with previously untreated MM were eligible for this phase II trial. VDT regimen (V 1.3mg/m2 on days 1, 4,15,18; D 20mg/m2 on days 1,15 and T 200 mg daily continuously) given on a 4-week cycle for a maximum of 8 cycles. Acyclovir (400 mg BID) and weight adjusted low-dose warfarin (1 or 2mg for absolute body weight <70kg or ≥70kg, respectively) was given for prophylaxis of herpes zoster and deep vein thrombosis (DVT), respectively. Response was assessed using the modified Blade criteria. Results: Forty patients (26 males, 14 females; median age 60.5, range 40-80 yrs) were enrolled on this study. Among these 58%(n=23) had stage III (Durie-Salmon) disease with a median b2 microglobulin of 3.7 (range 1.6-16.5 mg/L) and median LDH of 443 (range 152-129 IU/L). Thirty-nine patients are eligible for response evaluation (1 too early for assessment). Overall response rate (CR/nCR+PR) was 79.4% (n=31) with 38% (n=15) patients achieving CR/nCR. The median progression free (PFS) and overall survival (OS) has not been reached. At 1 year the PFS and OS is 81% and 97%, respectively (1 patient died from disease progression to leukemic phase). Toxicity: Neutropenia was the most significant hematological toxicity with grade 3 and 4 neutropenia observed in 22.5% and 2.5% of the patients, respectively. Only 1 (2.2%) patient had febrile neutropenia. Clinically significant neuropathy (grade ≥2) was seen in 20% while grade ≥2 palmer planter erythrodysesthesia was seen in 15% (n=6) of the patients. Other grade 3 non-hematological toxicities included pneumonia (20%), pleural effusion (10%), pulmonary embolism (2%), DVT (2%), congestive heart failure (5%) and interstitial pneumonitis (2%). Conclusion Although effective, steroid based treatment regimen can be associated with significant toxicity especially among patients with concurrent co morbid conditions such as hypertension and diabetes mellitus. Furthermore, recent investigations demonstrate that decreasing steroid doses may actually improve PFS and OS despite a comparatively low initial ORR. In this clinical trial we hypothesized that rational combination of novel myeloma agents may actually preclude the need to rely on high-dose steroids without significantly compromising ORR. Consistent with our expectations, the VDT regimen has ORR comparable to some of the steroid-inclusive triple drug combinations. The toxicity profile of this combination was acceptable and the regimen was well tolerated. Thus we note that VDT is an effective and well tolerated steroid-independent induction regimen for MM patients.

Abstract Background: Carfilzomib, a second generation proteosome inhibitor, is effective in the treatment of relapsed and refractory multiple myeloma (RRMM). Recent phase II and phase III trials have demonstrated the efficacy of weekly dosing strategies. The aim of this study was to examine high dose once weekly carfilzomib in combination with weekly dexamethasone and low dose weekly cyclophosphamide (wCCD) in RRMM. It was hypothesized that this may offer a potent yet convenient and more financially viable triplet-based treatment option than existing combinations. Methods: The MCRN-003/MYX.1 multi-centre single arm phase II clinical trial is run through the Myeloma Canada Research Network (MCRN) with support from the Canadian Cancer Trials Group (CCTG). Patients who had at least one but not more than three prior lines of therapy and who did not have proteosome inhibitor (PI) refractory disease were eligible. Treatment consists of carfilzomib (20 mg/m2 day 1 of first cycle then escalated to 70 mg/m2 for all subsequent doses) given on days 1, 8, and 15 of a 28-day cycle, plus weekly oral dexamethasone 40 mg and cyclophosphamide 300 mg/m2 capped at 500 mg on days 1, 8, 15 and 22. Treatment continues until progression or intolerance, except for cyclophosphamide which is discontinued after 12 cycles. The total sample size of 76 patients includes a 6 patient lead-in phase where safety at 70 mg/m2 was evaluated. The primary objective was to observe an overall response rate (ORR) ≥ 80% after 4 cycles of protocol therapy. Secondary endpoints include safety, toxicity, kinetics of and maximal response depth and overall survival. This analysis is based on the locked data base of 2018 July 13. Results: Of the 76 patients accrued 1 was subsequently determined to be ineligible on the basis of bortezomib refractory disease, and 1 did not receive any protocol therapy due to a cardiac event occurring post-study registration but prior to treatment commencement. All patients who received therapy were included in the analysis as per protocol inclusive of the bortezomib exposed patient. Among these 75 patients, median age was 66 years with 33% being > 70 years of age. Thirty-seven percent were female. Thirty-nine percent received 1 prior line, 44% received 2 prior lines and 17% received 3 prior lines of therapy. High risk cytogenetics [(t4;14), t(14;16) and del P53] were identified in 32%. Twenty percent had ISS stage III disease and 11% had R-ISS stage III disease. Prior PI and immunomodulatory drug exposure was noted in 87% and 81% respectively. Within the first 4 cycles of therapy 84% (95% CI, 76-92%) of patients achieved PR or better, with ≥ VGPR achieved in 52% and ≥ CR in 9% (table 1, p = 0.0006). There was a trend toward a better ORR after 4 cycles based on the presence or absence of high-risk cytogenetics (75% vs 94% respectively, p = 0.051) not meeting statistical significance. The median duration of follow-up at the time of data analysis was 13.9 months (range 0.2 to 22.8 months). 18 patients have died with an estimated 1-year OS of 80%. The cause of death as assessed by the investigator was myeloma in 13 patients with 3 dying from a cause possibly or probably related to the study intervention. During the first 4 cycles of treatment, non-hematologic toxicity ≥ grade 3 occurred in 33% of patients; most commonly infection (16%) and fatigue (7%). Grade 3/4 anemia was observed in 17%, thrombocytopenia in 33% and neutropenia in 20%. Grade 3 or greater hypertension was seen in 4%, dyspnea in 1%, pulmonary edema in 1% and thrombotic microangiopathy in 4%; all resolved with no long-term sequelae. To date 37 (49%) patients have discontinued carfilzomib, 11 due to toxicity and 16 due to disease progression. Conclusion: This prospective phase II study demonstrates that wCCD is a safe and effective regimen in the treatment of RRMM. The study met its primary endpoint demonstrating a ≥ 80% ORR after 4 cycles of therapy. These results compare favourably to published phase III data examining weekly carfilzomib and dexamethasone as well as the established twice-weekly dosing strategies. This regimen will be a useful triplet-based option for RRMM especially in patients refractory to immunomodulatory agents who would otherwise be ineligible for the carfilzomib-lenalidomide-dexamethasone combination.

Background: The combination of carfilzomib with immunomodulatory drugs (IMiDs) and dexamethasone is active in multiple myeloma (MM). Carfilzomib, thalidomide, and dexamethasone (KTd) has been studied in upfront MM treatment but has not been studied in the setting of relapsed/refractory myeloma (RRMM). The ALLG MM018/ AMN002 is an open-label phase II study of KTd in patients with RRMM. This study was conducted across 16 sites across Australia, New-Zealand, Singapore, South Korea and Taiwan. Method: Patients with RRMM with 1-3 prior lines of treatment were given carfilzomib [K: 20mg/m2 IV cycle 1 days 1 and 2, 56mg/m2 (36mg/m2 for patients age ≥75 years) from cycle 1 day 8 onwards], thalidomide (T: 100mg po nocte) and dexamethasone [dex: 40mg (20mg for patients age ≥75 years) po weekly], in a 28-day cycle. After 12 cycles, T was omitted, and K was given on days 1,2,15,16 and dex days 1,15 every 28-day cycles for a further six cycles. The primary endpoint was PFS. Secondary endpoints were ORR, overall survival, adverse events, and quality of life (QoL). The study had an 80% power to detect a ≥70% PFS at 6.5 months compared to historical ≤50% PFS at 6.5 months expected with Td (Kropff, M. et al. Haematologica 2012), at a significance level of 0.05. Results: This study has completed accrual. Eighty-three patients [median age of 66 years (42-85)] were enrolled with a median follow up of 15.9 (0.9-26) months. ORR rates were 86.4% (≥VGPR 70.2%). Median PFS was 20m (95% CI 15.9-26m). PFS at 6.5 months was 76.2% (95% CI 73.6-84.9%). Median OS has not been reached, and was 75% at 20 months. The most common grade ≥3/4 AEs were peripheral neuropathy (16%), upper respiratory tract infections (12%), dyspnoea (14%), and hypertension (10%). Grade ≥3/4 cardiac AEs occurred in 6%. The median carfilzomib dose that was delivered was 70.7% (32.8-92.6%) of the target dose. Thus far, 41% of patients have completed the intended 18 cycles of treatment. 21% of patients ceased therapy early. The most common reason for early treatment cessation was disease progression (30%) and adverse events (15%). Fifteen patients (18%) have died, 11 were due to MM, two from infection, one from an ischaemic cardiac event, and one from a traffic accident. QoL, as measured by the EQ-5D-5L instrument, remained stable throughout treatment. Conclusion: The ALLG MM018/AMN 002 study has met its primary endpoint. The KTd schedule as outlined in this study is efficacious in patients with RRMM, resulting in a prolonged PFS and a safety profile in line with previous reports for each of carfilzomib and thalidomide. KTd is an active option in jurisdictions where the cost of other IMiDs prohibits regulatory funding. Comparisons of efficacy and adverse events between the Caucasian and Asian populations will be presented at the meeting.

Abstract Patients with newly diagnosed multiple myeloma (MM) typically have responses to initial cytotoxic or steroid based therapy. Disease relapse occurs in all patients. As high as 90% of patients with relapsed or refractory disease will have over-expression of the multi-drug resistance (MDR) gene. Pharmacokinetic data suggest that prolonged exposure to high concentrations of doxorubicin can overcome MDR. Pegylated liposomal doxorubicin can theoretically achieve this goal as the angiogenic activity of the MM bone marrow is significantly increased. We proceeded with a phase II trial to evaluate the response rate of patients with relapsed or refractory MM (R/R-MM) to the DVd regimen. Eligible patients had clinically active R/R-MM following at least one prior cytotoxic based treatment regimen. Patients received intravenous (IV) pegylated liposomal doxorubicin 40 mg/m2 day 1, vincristine 2 mg day 1 and oral or IV dexamethasone 40 mg daily days 1–4. Cycles were repeated every 28 days for a minimum of 6 cycles and 2 cycles after best response. Myeloma parameters were measured at the start of each cycle. SWOG criteria were used to determine response. Thirty-five patients (21 male and 14 female) with R/R-MM clinically active disease were enrolled. Median age was 59 years (range 43–87). Patients received a median of 2 (range 1–4) prior cytotoxic based treatments. All patients received at least one cycle of treatment (median=5; range 1–12) and were evaluable for response. Ten (29%) patients responded to therapy; 5 partial responses (PR &gt; 50%) and 5 responses (R &gt; 75%) were observed after a median of 2 cycles (range 1–9). Median progression free survival of responding patients (PR + R) was 4.5 mos. (range 0.67–44.8). Patients achieving R had a median progression free survival of 32.5 mos. (3.0–44.8). Thirteen (37%) patients had stable disease (SD) for a median of 1.4 mos. (range 0.8–9.9). Twelve (34%) patients had progressive disease after a median of 1 cycle (range 1–5). The most common toxicities were hematologic; there were four occurrences of febrile neutropenia. Three patients experienced grade 3 constipation and one grade 3 palmar-plantar erythrodysethesia was observed. This study suggests that in patients with R/R-MM, DVd alone yields response rates similar to bortezomib with patients achieving an R experiencing a durable plateau phase. Ongoing studies of DVd in combination with thalidomide or CC-5013 in patients with R/R-MM have resulted in higher and better quality response rates (comparable to autologous SCT) translating to a durable progression free survival. We would not recommend the DVd regimen in patients with R/R-MM without the addition of an immune modulator such as thalidomide.

Abstract Abstract 197 Supported by an unrestricted grant from Genzyme Corporation. Fludarabine (Flu) melphalan-alemtuzumab is a well tolerated, reduced intensity conditioning regimen for HCT. Clofarabine (Clo), a second generation nucleoside analog with excellent activity in acute leukemia, might enhance disease control over Flu. We report outcomes of a completed phase I and ongoing phase II study of CMA conditioning for allogeneic peripheral blood HCT. Tacrolimus was administered as GVHD prophylaxis. For the phase I cohort, one pt was enrolled per dose level, until the first DLT or until 2 had grade 3 toxicity. Dose level 1 consisted of: clo 10 mg/m2/day on d −7 to −3 and melphalan 100 mg/m2 on day −2. Clo was increased by 10 mg/m2/day per cohort until 40 mg/m2/day. Then, melphalan was increased by 20 mg/m2 until 140 mg/m2. Alemtuzumab was given at a fixed dose of 20 mg/day on d −7 to −3. Twelve pts were accrued in the phase I portion of whom three remain in remission at 26, 22 and 21 months. Forty pts, median age 53 (24–69), have been accrued in the phase II study of whom 16 had related and 24 unrelated donors. 20 had AML/MDS (6 refractory, 4 CR2, 9 CR1, 1 untreated MDS), 16 NHL (6 refractory, 9 chemosensitive relapse, 1 CR1) 2 CLL, 2 MPD. ASBMT risk score was high in 14, intermediate in 14, and low in 12. Performance score was 0 in 19, 1 in 17, 2 in 2, and not documented in 2 patients. The phase II dose was initiated at Clo 40 mg/m2/day x 5 days and melphalan 140 mg/m2. Twenty-four pts received this dose. Grade 3 renal toxicity occurred between day −7 and day +7 in 4 of 24 (17%) pts receiving this dose. The phase II dose was then reduced to Clo 30 mg/m2/day x 5 days and melphalan 140 mg/m2, and used to treat 16 pts. One pt with preexisting cardiomyopathy and refractory AML died during conditioning from cardiovascular failure. No grade 3 renal toxicity has been observed in this cohort and 3 pts had reversible grade 2 renal failure. Other toxicities included: gr 2–3 reversible ALT elevation between day −2 and day +5 in 8 pts; gr 2 reversible bilirubin elevation in 1 pt. No grade 3–4 hand foot syndrome or VOD occurred in this cohort. All evaluable pts engrafted. Twenty of 24 pts had full donor CD3 chimerism on day 30 and 2 had mixed donor chimerism. 11 pts had gr II aGVHD, and 3 had gr IIII/IV aGVHD. 7 have cGVHD.With a median follow-up of 313 days (19–607), 24 of 40 pts (60%) in the phase II portion of the study remain in remission. Eight have relapsed, 4 of whom have died. Eight others have died of treatment-related causes (7 after Clo 40 and 1 after Clo 30). Estimated one year survival is 72% (95%CI, 56–88) and PFS is 63% (45–81%). Neither dose of Clo (40 vs 30), donor type (MUD vs related), age (< 50 vs >50) affected outcomes. One year PFS was 56% (28–84) for NHL and 68% (46–90) for AML/MDS (P=NS). One year PFS was 43% (15–71%) for ASBMT high risk pts vs 70% (50–90%) for ASBMT low/intermediate risk pts (P=0.01; Figure 1). Conclusions: Clofarabine - melphalan - alemtuzumab conditioning induces durable remissions in a substantial fraction of patients with advanced hematologic malignancies. Clo 30/Mel 140 has an excellent safety profile. Disclosures: Off Label Use: clofarabine for transplant conditioning.

7547 Background: Bortezomib, administered on a twice-weekly schedule, is now a standard part of treatment for patients with multiple myeloma. Weekly bortezomib schedules have shown activity in other cancer types, and are more convenient than twice weekly schedules. In this multicenter, community-based phase II trial, we evaluate the feasibility, toxicity, and efficacy of weekly bortezomib in pts with previously treated multiple myeloma. Methods: Eligibility criteria included a diagnosis of multiple myeloma treated with 1 or 2 previous systemic regimens (only 1 if first-line therapy included high-dose therapy); ECOG PS 0–2; creatinine < 2.0 mg/dL; WBC ≥ 3000/μL; ANC > 1000/μL; platelets ≥ 50,000/μL; no peripheral neuropathy > grade 1; informed consent. All pts received bortezomib 1.6mg/m2 IV on days 1, 8, 15, and 22 of each 5-week cycle. Pts were reevaluated at 10-week intervals; treatment continued for 8 cycles (40 weeks) or until myeloma progression. Results: Between 5/04 and 12/05, 37 pts entered this trial. Pt characteristics: median age 70 years; male/female, 20/17; 24 pts (65%) had received 2 previous regimens (previous high dose therapy, 2 pts); elevated β-2 microglobulin, 27 pts (73%). Of 26 pts evaluated, 13 pts (50%) had major responses, 11 pts (42%) stable disease, and 2 pts (8%) had progression. After a median follow-up of 7 months, projected median PFS is 9.6 months; overall survival at 1 year is 81%. Weekly bortezomib was well tolerated by most pts. Grade 3/4 toxicities included fatigue (21%), diarrhea (11%), neutropenia (7%), thrombocytopenia (4%), all others < 5%. No grade 3/4 neuropathy occurred. Only 1 pt required bortezomib dose reduction during treatment, and 2 pts discontinued treatment because of toxicity (myelosuppression, 1; fatigue/dehydration, 1). Conclusions: Weekly bortezomib is a convenient, well tolerated treatment for pts with previously treated multiple myeloma. Overall response rates with this schedule are similar to those previously reported with the standard twice-weekly schedule. Further followup is necessary to better evaluate the duration of response and the incidence of cumulative toxicities. [Table: see text]

Background: Daratumumab, a human anti-CD38 monoclonal antibody, 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. The phase 2 DARAZADEX study will evaluate the efficacy and safety of daratumumab plus azacitidine and dexamethasone in RRMM patients previously treated with daratumumab. Pre-clinical data from our laboratory has demonstrated that azacitidine induces a 1.2 - 2.4 increase in CD38 median fluorescent intensity (MFI) in a dose-dependent manner across four different MM cell lines. (Figure 1A) Using an immortalized transgenic natural killer (NK) cell line to mediate lysis, we observed a significant increase in antibody-dependent cell-mediated cytotoxicity (ADCC) in the azacitidine-treated MM cells as opposed to control. Importantly, this increase in ADCC correlated with CD38 MFI upregulation. (Figure 1B). Based on this data we hypothesize that azacitidine, by upregulating the expression of CD38, can potentially increase the ADCC and efficacy of daratumumab on multiple myeloma cells and help reverse daratumumab resistance. Methods: In this single-arm, 2-stage, phase II study, approximately 23 RRMM patients in the United States will be treated with combination of daratumumab, azacitidine, and dexamethasone. Eligible patients must have progressed on ≥2 lines of prior therapy, including an immunomodulatory drug (IMiD) and proteasome inhibitor, and have previously been treated with daratumumab with most recent daratumumab treatment being at least 6 months prior to enrollment to allow for CD38 normalization. Patients who were previously primary refractory to daratumumab will be excluded from the study. Patients will receive azacitidine at the standard 75 mg/m2 dose 5 days consecutively every 4 weeks starting day -7 to day -3 of Cycle 1 and then Day 22-26 of Cycle 1-3, and subsequently Day 1-5 of Cycle 5 and thereafter until disease progression or intolerance, with dose modifications for toxicities. Daratumumab will be administered intravenously at the standard dose of 16 mg/kg, with first dose administered on day 1. Daratumumab will be dosed in standard fashion: weekly for 8 doses (induction phase), every two weeks for 8 doses (consolidation phase), and then every 4 weeks thereafter (maintenance phase). Daratumumab will be switched to the subcutaneous formulation at a later timepoint. There will be no dose modifications for daratumumab. Dexamethasone at a dose of 40 mg PO (or IV if PO is not available) will be given weekly for Cycle 1 and 2, after which the pre-infusion medication dose can be reduced to 20 mg and non-pre-infusion dose can be reduced or stopped based on investigator's discretion. Bone marrow biopsies will be done within 14 days prior to Cycle 1 day -7 (first azacitidine dose) and on Cycle 1 day 1 prior to first daratumumab infusion (or after completion of first 5 days of azacitidine and prior to first daratumumab infusion), for correlative studies. (Figure 1C) Simon's minimax two-stage design will be used with a safety lead-in cohort of 6 patients. In the first stage, a total of 13 patients will be enrolled (including the safety cohort), and if there is ≥2 responses in 13 patients the study will enroll an additional 10 patients; if there is ≤ 1 responses in 13 patients the study will be stopped. Primary objective is to evaluate the efficacy, as determined by the overall response rate (ORR) of this combination. Secondary objectives include duration of response per international myeloma working group (IMWG) criteria, safety and toxicity, and the 1-year OS and PFS of this combination. An additional secondary objective is to evaluate the changes in CD38 expression on plasma cells induced by azacitidine in patients with RRMM and identify any correlation of this change with depth and duration of response. The exploratory objective will be to evaluate the tumor microenvironment changes induced by azacitidine via mass cytometry (CyTOF). NCT04407442.

Abstract Abstract 205 Introduction: Bendamustine has shown considerable activity in monotherapy for lymphoid malignancies including chronic lymphocytic leukemia (CLL). In vitro studies have demonstrated synergistic pro-apoptotic effects of bendamustine and the CD20 antibody rituximab (BR) in primary CLL cells. Encouraging results have also been obtained using the BR combination treatment in previously treated CLL. This multicenter phase II trial (CLL2M) is the first study assessing the efficacy and toxicity of bendamustine in combination with rituximab in previously untreated CLL patients (pts). Patients and Methods: Between March 2007 and September 2008 117 pts with untreated CLL requiring therapy were enrolled into the protocol. Bendamustine was given at a dose of 90 mg/m2 on day 1 and 2, combined with 375 mg/m2 rituximab for the first cycle and 500 mg/m2 for subsequent cycles. BR treatment was administered every 28 days for up to 6 courses. Blood samples were taken for analysis by fluorescence in situ hybridization (FISH), the IgVH mutational status and expression of ZAP70/CD38. Minimal residual disease (MRD) was evaluated in peripheral blood and bone marrow by 4-color flow cytometry. Results: Data on the entire study population of 117 pts (median age 64 years) with a total of 583 treatment cycles are available. As of June 2009 the median observation time was 15.4 months (mo). 11.1% of the pts presented with stage Binet A, 41.0% with Binet B and 47.9% with Binet C disease. A mean number of 5.0 courses were delivered. 114 pts were evaluable for toxicity, 110 for response and 113 for progression free survival (PFS). The most frequent adverse events based on 583 treatment cycles were myelosuppression and infections: grade 3/4 anemia occurred in 4.9%, grade 3/4 leukopenia in 14.6%, grade 3/4 neutropenia and thrombocytopenia in 6.5% and 6.1% of all given courses, respectively. 29 episodes of CTC grade >3 infections were documented (5.1% of all courses). Treatment related mortality occurred in 2.6% of the pts: one liver failure after attempt of suicide with antihistamines, one fatal pneumonia and one sepsis in neutropenia. The overall response rate was 90.9% with 32.7% (36 pts) clinical complete remissions (CR). A nodular partial remission (nPR) was achieved in 2.7% (3 pts) and a partial response (PR) in 55.5% of the pts (61 pts), respectively. 9.1% of the pts (10 pts) had stable disease (SD) whereas none of the pts was progressive (PD). After 18 mo 75.8% of the pts were still in remission, median PFS has not been reached. An MRD level below 10E-4 was observed after completion of therapy in 29 of 50 evaluable pts in peripheral blood, while 7 of 25 pts achieved MRD negativity in bone marrow. Differences in response were observed among the genetic subgroups: 19 of 21 pts with 11q- achieved a remission with 10 PR and 9 CR (ORR: 90.5%). Accordingly, 17 of 19 patients with +12 responded (14 PR, 3 CR, ORR: 89.5%). In the high-risk group with 17p-, 3 of 7 pts showed a partial response (ORR: 42.9%). 56 of 63 pts (ORR: 88.9%) with unmutated IgVH status responded to BR. Conclusion: Bendamustine plus rituximab (BR) is effective and safe in the first-line treatment of CLL. Major side effects (myelosuppression and infections) were infrequent. Based on these encouraging phase II data the German CLL Study group is presently investigating the efficacy of BR in comparison to fludarabine-based immunochemotherapy (FCR) in the first-line treatment of CLL within a randomized phase III trial (CLL10 protocol).

Abstract Abstract 3856 Poster Board III-792 Background Lenalidomide (Revlimid®, Len) plus dexamethasone (Dex) is approved for the treatment of relapsed or refractory multiple myeloma (MM) patients following ≥1 prior therapy. mTOR inhibitor RAD001 has been studied as a single agent in MM, and although well tolerated, did not have single agent activity. Given the increased toxicity noted with pulsed high dose steroids, we sought to study a non-steroid containing oral regimen for the treatment of relapsed MM predicated upon our previous studies which demonstrated synergistic anti-MM activity of mTOR inhibitors when combined with len. Here, we extended our in vitro observations to a phase I clinical trial combining RAD001 with len in patients with relapsed or refractory MM. The primary objective was to assess toxicity of this combination and to determine the maximum tolerated dose (MTD). The secondary objective was to determine the activity of this combination. Methods Patients with relapsed and refractory MM were assigned to len and RAD001 to be taken for 21 days of a 28 day cycle. Dose escalation followed a modified Fibonacci design. Patients were allowed to continue therapy until disease progression or unacceptable toxicity. Patients received concomitant anti-thrombotic (aspirin 81 or 325 mg/day) therapy. Response was assessed according to modified EBMT and Uniform Criteria, and toxicities were assessed using NCI CTCAE v3.0. Results Eighteen MM patients have been enrolled to date. One patient in cohort 1 (Len: 10mg and RAD001: 5 mg x 21 days) developed grade 3 neutropenia requiring expansion of the cohort. Cohort 2 (Len: 15mg and RAD001: 5 mg x 21 days) also required expansion because of grade 4 thrombocytopenia noted in 1 patient. Dose limiting toxicities included grade 4 neutropenia and thrombocytopenia in 2/3 patients in cohort 3 (Len: 20mg and RAD001: 5 mg x 21 days). The MTD for patients with MM was therefore declared at 15 mg of len and 5mg of RAD001 for 21 days with a 7 day rest period. Apart from the hematological toxicities expected with the combination, patients otherwise tolerated the regimen well. Most common (≥10%) grade 1 / 2 events included nausea, fatigue, dyspnea, diarrhea, constipation, neuropathy and muscle cramps, all of which were manageable with supportive care. No thromboembolic events were noted. Grade 3 / 4 adverse events ≥ 5% included thrombocytopenia (11%) and neutropenia (22%). Fifteen patients have finished at least 2 cycles of therapy: 8 of 15 patients have either stable disease (SD: 1), minimal response (MR: 5) or a partial response (PR: 2), including 7 of 9 patients treated at the recommended MTD for an overall response rate (MR or better) of 50% (90% CI: [30.76%]). One patient with SD continued therapy for a total of 10 cycles, without significant toxicities. Conclusions The combination of Len plus RAD001 is a well tolerated regimen with predictable hematological toxicities. Promising responses were noted in this heavily pretreated patient population. This combination provides an oral steroid free combination alternative strategy which warrants future evaluation in phase II studies.

Abstract Abstract 2309 Poster Board II-286 Background There is a role for novel preparative regimens in multiple myeloma to improve the outcome after high-dose chemotherapy and autologous hematopoietic stem cell transplantation (auto HCT). Bortezomib is an active agent in newly diagnosed or relapsed multiple myeloma, and has synergistic activity with melphalan. We conducted a randomized phase II trial to determine the safety and efficacy of adding bortezomib to a preparative regimen of arsenic trioxide (ATO), ascorbic acid (AA) and melphalan. Methods auto HCT, with preparative regimen melphalan 100 mg/m2 IV on days -4 and -3, AA 1000 mg/day IV on days -9 to -3 and ATO 0.25 mg/kg IV on days -9 to -3. Patients were randomized to 3 arms; no bortezomib (arm 1), bortezomib 1 mg/m2 on days -9, -6 and -3(arm 2), and bortezomib 1.5 mg/m2 on days -9, -6 and -3 (arm 3). Primary endpoints were complete response (CR), NCI grade 4 toxicity, and overall survival (OS). Results In arms 1, 2 and 3, median intervals between diagnosis and auto HCT were 12.2, 9.6 and 8.8 months; median follow up in all surviving patients was 20 months (range 10 to 31). CR+near CR rates in arms 1, 2 and 3 were 35%, 30% and 25%. Grade 3–4 toxicity was seen in 6 patients in arm 1 (mucositis 3, dyspnea 1, acute renal failure 1, pleural effusion 1), 6 patients in arm 2 (mucositis 3, diarrhea 1, pneumonia 1 and hydronephrosis 1) and 6 patients in arm 3 (pulmonary edema 2, mucositis 1, intestinal obstruction 1, low back pain 1, elevated transaminases 1). The most common adverse events were nausea, diarrhea and pedal edema. Grade 1–2 weight gain due to fluid retention was seen in 84%, 70% and 95% of patients in arms 1, 2 and 3. Median time to neutrophil engraftment (ANC >500/dl) was 10 days in each arm. Median OS has not been reached in any of the 3 arms. Median progression-free survival (PFS) times were18.6, 13.2 and 17.5 months. OS was significantly shorter in patients with relapsed disease (0.00001) and cytogenetic abnormalities at auto HCT (0.0002). Conclusions Adding bortezomib to a preparative regimen of ATO, AA and high dose melphalan is safe and well tolerated in patients with multiple myeloma. There was no significant impact of adding bortezomib at either dose on the CR rate, grade 3-4 toxicity or OS.

Abstract Abstract 4936 Despite recent advances in the treatment of MM, the disease remains incurable and many of the most effective, newer combination therapies are accompanied by significant side effects that have a major negative impact on the patient's quality of life. Pegylated liposomal doxorubicin (PLD) and bortezomib have shown anti-MM efficacy in the laboratory and for the treatment of previously treated MM patients, leading to FDA approval for patients who have failed one prior therapy. Using our severe combined immunodeficiency-hu murine models of human MM, we have previously demonstrated that lower doses of PLD administered daily are more effective and better tolerated than higher amounts given weekly. Moreover, the combination of bortezomib and dexamethasone has been shown to be effective for previously untreated MM patients. Prior studies by our group have shown that combining chemotherapy including PLD with bortezomib administered at 1.0 mg/m2 on days 1, 4, 8, and 11 of a 28-day cycle rather than the standard 1.3 mg/m2 on the same days of a 21-day schedule is effective for MM patients with relapsed or refractory disease and associated with a reduction in the incidence and severity of peripheral neuropathy. Thus, we conducted a single-arm multi-center phase II study for previously untreated MM patients to evaluate the combination of intravenously administered dexamethasone, bortezomib and PLD (DVD). The treatment consisted of intravenous administration of 40 mg dexamethasone followed by 1.0 mg/m2 bortezomib and finally 5.0 mg/m2 PLD on days 1, 4, 8, and 11 of a 28-day cycle. Patients were treated to a maximum response plus two additional cycles or completed a maximum of eight cycles of therapy without disease progression. To date, 22 (of 35 planned) patients have been enrolled with a median age of 64 years (range, 42-79 years). The majority of those on study (68 %) were diagnosed with International Staging System II or III MM. Four patients are too early to assess for response. To date, among the 18 evaluable patients, 16 (89%) have shown objective responses to the DVD regimen, including 2 complete responses (11%), 8 partial responses (44%) and 6 minimal responses (33%). The other 2 patients (11%) had stable disease, with one of these subjects showing a continuing reduction in M-protein after 2 cycles of therapy to date. Thus, disease control was achieved in all patients. To date, no patient has shown progressive disease after 2+ - 12+ months of follow-up. Six patients experienced grade 3 adverse events and one patient with a prior history of pulmonary interstitial fibrosis developed a grade 4 toxicity (shortness of breath). Grade 3 adverse events in three of the six patients were judged not to be related to the study treatment. The most common grade 3 adverse event was reversible neutropenia (n=2). To date, only 2 patients (9%) have developed peripheral neuropathy (grade 1). Notably, there have been no cases of stomatitis or hand-foot syndrome. Thus, these results suggest that the DVD regimen using a modified schedule and doses of the combination of intravenous dexamethasone, bortezomib and PLD is a well tolerated treatment that produces high response rates for previously untreated patients with multiple myeloma.
