Background: The advent of novel therapies has led to tremendous progress in the treatment of multiple myeloma (MM). However, management of patients with high-risk disease who have failed approved agents and have rapidly progressive disease with cytopenias continues to be challenging. While palliative care is an option, many patients hope to qualify for a clinical trial option. Here we report results of a 28-day metronomic therapy (METRO-28) consisting of continuous administration of very low doses of classical chemotherapeutic agents. Sixteen-day cycles of metronomic therapy were previously shown to have a favorable response with acceptable toxicity profiles in MM patients (Papanikolaou et al. Haematologica 2013). Aim: To investigate the efficacy and toxicity in patients with high-risk relapsed refractory MM (RRMM) ineligible for clinical trial options receiving 1 cycle of METRO-28. Method: We retrospectively analyzed the clinical outcomes of 106 RRMM, treated with 1 cycle of 28-day metronomic chemotherapy at the Tisch Cancer Institute - The Mount Sinai Hospital. METRO-28 consists of 6 agents: dexamethasone 8 mg on days 1 through 4, 7 through 10, 13 through 16, 19 through 22 and 25 through 28; bortezomib 1 mg/m2 on days 1, 4, 7, 10, 13, 16, 19, 22, 25, 28; cisplatin 1 mg/m2 daily; doxorubicin 1 mg/m2 daily; thalidomide 100 mg daily; and vincristine flat dose 0.06 mg daily. METRO-28 was administered through a central line in either the inpatient or outpatient setting. Result: Our cohort of 106 RRMM patients has a median age of 65 years (range: 35-85) and at a median of 59 months from time of diagnosis; 42% were females. They had a median of 7 prior lines of therapy (range: 1 - 25); with 73% triple- and 58% penta-refractory cases. Prior autologous transplantation was utilized in 69% of patients including tandem transplants in 30%. Moreover, 78% of patients carried high-risk cytogenetic features, including 1q21 duplication/amplification (89%), 17p deletion (49%), t(4;14) (17%), t(14;16) (17%) or t(14;20) (3%). At the time of METRO-28 initiation, patients were cytopenic with grade 3 and 4 anemia (21%), neutropenia (8%) and thrombocytopenia (23%). Profound cytopenias in some patients led to early discontinuation of treatment; forty-three patients (41%) received the full 28-day course of METRO-28, while 11%, 17%, 20% and 11% were treated for <1 week, <2 weeks, <3 weeks or <4 weeks, respectively. Grade 3-4 cytopenia increased: anemia 66%, leucopenia 61%, neutropenia 55% and thrombocytopenia 76%. On an intent to treat basis (106 patients), the deepest response included 2% stringent complete response (sCR), 7% near complete response (nCR), 7% very good partial response (VGPR), 28% partial response (PR), 11% minimal response (MR) and 12% stable disease (SD). Only 43 patients (41%) completed all 4 weeks of METRO-28 and had a 72% overall response rate (ORR) and 88% clinical benefit rate (CBR). Seventy-four percent of these patients were able to move on to new therapies, including novel agents and clinical trials. Their overall survival (OS) was 11.8 months (range: 6.1-NE) as opposed to an OS of 4.2 months (range: 3.4-7.2) for patients with <4 weeks of METRO-28. Sixty-three patients had their treatment interrupted: 34 due to disease progression or absence of response, 18 due to bacterial or viral infections and 11 due to hematologic toxicity. Conclusion: Giving 1 cycle of METRO-28 is better tolerated in patients with good hematologic reserve and offers an opportunity for a clinical benefit and a bridge to a subsequent treatment option for these advanced refractory myeloma patients.

Abstract INTRODUCTION: Multiple Myeloma (MM) is an incurable hematologic cancer characterized by multiple recurrences. With each recurrence, patients have a lower probability of response and duration of response is shorter. Therefore, there is an unmet need to improve outcomes in relapsed/refractory multiple myeloma (RRMM). There is a shortage of data describing clinical features and outcomes in these patients in real-world practice, particularly with regard to differences in outcomes by baseline cytogenetic risk. To help address this information gap, this study analyzed data from a cohort of RRMM patients in France. METHODS: A retrospective observational review of medical records was conducted in a cohort of 200 patients with RRMM in France. Patients were selected (based on randomly generated first letter of last name) from the caseloads of 40 hematology/oncology providers across France practicing mainly in academic hospitals. Inclusion criteria were: ≥18 years of age at initial MM diagnosis; first determined to have RRMM between January 1, 2009 and December 31, 2011, where RRMM was defined by (1) first-line (induction) regimen of chemotherapy with or without stem cell transplant (SCT) and with or without other post-induction/SCT therapy and (2) disease progression while on or at any time after completion of first-line therapy. Patients could be alive or deceased at the time of record abstraction. Baseline cytogenetic risk was defined as follows: high-risk: cytogenetic abnormalities del(17p), t(4:14), or t(14;16); unknown/unassessed risk: patients for whom cytogenetics were unavailable; or standard-risk: all patients with known cytogenetics not classified as high-risk. Patients were assessed for treatment response, overall survival (OS) and progression-free survival (PFS) from date of first relapse (study index date). All analyses were descriptive. Survival was assessed using the Kaplan-Meier (K-M) method. RESULTS: Demographic and clinical characteristics of the study sample are presented in Table 1. A total of 55 high-risk and 113 standard-risk patients were identified; risk category was unknown or unassessed for 32 patients. Among all patients, mean (SD) age at RRMM diagnosis was 66.3 (8.9) years and 62% of the sample was male. Lenalidomide + dexamethasone was the most common second-line systemic regimen initiated (50% of high-risk patients, 59.5% of standard-risk patients receiving second-line treatment). A total of 114 patients (57%) initiated a third-line treatment. Despite clinical response in second-line treatment occurring sooner in high-risk patients (median: 106 days) than in standard-risk patients (median: 237 days), physician-assessed overall response rate (ORR) was lower in high-risk patients (63%: 17% complete response, 46% partial response) than standard-risk patients (91%: 26% complete response, 65% partial response) across all second-line treatments combined (Table 2).. For third-line treatment, ORR was lower in high-risk patients (54%: 12% complete response, 42% partial response) than standard-risk patients (74%: 9% complete response, 65% partial response). Among patients who initiated a second-line treatment (n = 192), 47.4% were deceased at the time of data collection. From second-line initiation, K-M estimates of 1- to 5-year OS and PFS were substantially lower for high-risk patients versus standard-risk. Specifically, the proportions of patients still alive 1, 3, and 5 years after second-line treatment initiation were 73%, 51%, and 36%, respectively, for high-risk patients and 94%, 73%, and 61% for standard-risk patients. The proportions of patients without disease progression at 1, 3, and 5 years after second-line initiation were 48%, 13.5%, and 5% for high-risk patients and 82%, 42%, and 14% for standard-risk patients. CONCLUSIONS: The importance of cytogenetic risk classification as a prognostic factor in RRMM was apparent in this retrospective review, in which patients with high-risk cytogenetics had less favorable outcomes in terms of ORR, OS, and PFS than standard-risk patients. Decreased response rate and lower PFS and OS was documented among patients with high-risk cytogenetics, which is in contrast to shorter time needed to achieve best clinical response in this subgroup. Results from this real-world study provide further confirmation of the unmet medical need presented by RRMM, especially for patients with high-risk cytogenetics. Disclosures Lin: Takeda: Employment.

Abstract Abstract 3965 INTRODUCTION: So far, monoclonal antibodies have not yielded convincing therapeutic success in multiple myeloma (MM). Therefore, the discovery of an effective targeted antibody against MM would open new perspectives for patients with relapsed or refractory MM and for the combination with established therapies. Cetuximab is an anti-epidermal growth factor receptor (EGFR) antibody. EGFR is also expressed on multiple myeloma (MM) plasma cells and bone marrow stromal cells. Recently, the inhibition of EGFR by small molecule inhibitors has been shown to induce apoptosis in primary myeloma cells revealing a synergistic effect with dexamethasone. Therefore, the anti-EGFR antibody cetuximab might be of clinical benefit in the treatment of MM, especially in combination with dexamethasone. Here we show the final results of the first clinical trial with an anti-EGFR antibody in MM. METHODS: Cetuximab was administered once weekly in standard dose to patients with refractory or relapsed MM who had previously received at least one line of prior treatment including autologous stem cell transplant (ASCT). Patients who still were candidates for ASCT were not included. Dexamethasone 20 mg on day 1–3 of each cycle was added starting week 5 in case of tumor progression or week 9 if no partial response (PR) or complete response (CR) was achieved with cetuximab alone. Planned treatment duration was 16 weeks (primary endpoint) with the possibility to prolong treatment in case of stable disease (SD) or response. RESULTS: In total, 15 patients have been enrolled. Seven patients were treated for a minimum of 16 weeks and 5 of those patients received cetuximab for at least 28 weeks. One patient received cetuximab treatment as single agent for more than one year. Thrombocytopenia, hyponatremia and acneiform rash were the most common CTC grade 3 or 4 side effects. Acneiform rash CTC grade 1 occurred in all patients and 3 patients suffered from acneiform rash CTC grade 3. After 16 weeks (primary endpoint) cetuximab in combination with dexamethasone induced 4 responses (3 minimal responses (MR) and 1 partial response (PR)) and achieved stable disease (SD) in 1 patient. Cetuximab as single agent induced SD in 2 patients. This results in an intention-to-treat overall response rate (ORR; CR+PR+MR) of 27% and a clinical benefit rate (at least SD) of 47%. Five of the 15 patients included did not receive the planned 16 weeks of treatment due to progressive disease (PD); three patients stopped treatment due to intolerable side effects. Six patients were treated more than 16 weeks: 1 patient received cetuximab as single agent and had SD more than a year and 5 patients continued treatment with cetuximab and dexamethasone in combination. CONCLUSIONS: Cetuximab is feasible and safe in MM patients. It demonstrated moderate efficacy in highly pre-treated patients, especially in combination with dexamethasone. Due to its unique mode of action and favorable side effect profile, cetuximab should be evaluated as combination partner for established substances such as bortezomib or lenalidomide to increase response rates both in therapy naive and in refractory patients. Disclosures: No relevant conflicts of interest to declare.

Purpose Thalidomide and lenalidomide are immunomodulatory drugs (IMiDs) that produce high remission rates in the treatment of multiple myeloma. Pomalidomide is a new IMiD with high in vitro potency. We report, to our knowledge, the first phase II trial of pomalidomide administered in combination with low-dose dexamethasone for the treatment of relapsed or refractory multiple myeloma. Patients and Methods Pomalidomide was administered orally at a dose of 2 mg daily on days 1 through 28 of a 28-day cycle. Dexamethasone 40 mg daily was administered orally on days 1, 8, 15, and 22 of each cycle. Responses were recorded using the criteria of the International Myeloma Working Group. Results Sixty patients were enrolled. Thirty-eight patients (63%) achieved confirmed response including complete response in three patients (5%), very good partial response in 17 patients (28%), and partial response in 18 patients (30%). Responses were seen in 40% of lenalidomide-refractory patients, 37% of thalidomide-refractory patients, and 60% of bortezomib-refractory patients. Responses were seen in 74% of patients with high-risk cytogenetic or molecular markers. Toxicity consisted primarily of myelosuppression. Grade 3 or 4 hematologic toxicity consisted of anemia (5%), thrombocytopenia (3%), and neutropenia (32%). One patient (1.6%) had a thromboembolic event. The median progression-free survival time was 11.6 months and was not significantly different in patients with high-risk disease compared with patients with standard-risk disease. Conclusion The combination of pomalidomide and low-dose dexamethasone is extremely active in the treatment of relapsed multiple myeloma, including high response rates in patients refractory to other novel agents.

8508 Background: High-risk (HR) multiple myeloma (MM) still has a significant impaired prognostic outcome. Addition of CD38 monoclonal antibodies to standard-of-care regimens significantly improved response rates and depth of response in newly diagnosed (ND) and relapsed/refractory MM patients (pts). Here, we report the prespecified end of induction interim analysis (IA) of the investigator-initiated GMMG-CONCEPT trial (NCT03104842), evaluating the quadruplet regimen isatuximab plus carfilzomib, lenalidomide and dexamethasone (Isa-KRd) in HR NDMM pts. Methods: 153 pts with HR NDMM are planned to be included into the trial. HR MM is defined by the presence of del17p or t(4;14) or t(14;16) or > 3 copies 1q21 and ISS 2 or 3 stage disease. Pts receive 6 cycles of Isa-KRd induction, 4 cycles of Isa-KRd consolidation and Isa-KR maintenance. Transplant eligible pts (arm A) undergo high-dose therapy. Transplant ineligible pts (arm B) receive 2 additional cycles of Isa-KRd induction. The primary endpoint is MRD negativity measured by next-generation flow after consolidation. This IA reports on overall response rates (ORR) after induction. Additional MRD analysis will be presented. Results: 50 pts (46 arm A, 4 arm B) were included in the IA population for ORR. HR MM was defined by del17p in 52%, t(4;14) in 38%, t(14;16) in 12% and > 3 copies 1q21 in 42%. 39/46 pts in arm A and 4/4 pts in arm B completed induction treatment. ORR was 100%, with 5 pts (10.0%) showing partial response (PR), 22 (44.0%; including 4 in arm B) very good partial response (VGPR) and 23 (46.0 %) complete response (CR). Median stem cell yield was 6.6 × 106CD34+ cells/kg. Grade 3/4 treatment-emergent adverse events (≥ 10%) with Isa-KRd included neutropenia (34.0%), leukopenia (26.0%) and thrombocytopenia (14.0%). Main non-hematologic toxicities grade 3/4 were hypertension (12.0%) and infection (8.0%). Conclusions: To the best of our knowledge, we report for the first time on a trial investigating solely HR NDMM and Isa-KRd quadruplet treatment. Isa-KRd induction induces deep responses in HR MM pts. The overall safety profile of Isa-KRd is expected and consistent with previous reports. The study is ongoing, with pts continuing to be included. Clinical trial information: 03104842 .

Abstract Background: Multiple myeloma (MM) is an incurable disease with a anticipated overall survival (OS) ranging from months to decades. Modest improvements in OS have been made with high-dose chemotherapy with peripheral blood stem cell transplant (PBSCT), but to date prognostic factors have a greater impact on OS than do individual therapies. Patients with adverse risk factors such as elevated beta-2 microglobulin (B2M), plasma cell labeling index, deletions of the long arm of chromosome 13 by metaphase cytogenetics (del 13q) require innovative new treatment strategies. Bortezomib has significant activity in patients with both newly diagnosed and relapsed/refractory MM, but its specific role in patients with adverse features has not yet been defined. Methods: Patients with newly diagnosed “high-risk” myeloma (B2M ≥ 5.5., PCLI ≥ 1, or del 13q) and adequate organ and functional status were eligible. Patients were treated with bortezomib 1.3 mg/m2 day 1, 4, 8, and 11 every 21 days for 8 cycles as induction. After induction, patients were scheduled to receive bortezomib 1.3 mg/m2 every other week indefinitely. Elective peripheral stem cell mobilization (growth factor alone) was allowed after 4 cycles of bortezomib. Patients relapsing on maintenance schedule were to have the full induction schedule resumed. Responses were by the EBMT criteria but a very good partial response category was included. The primary end-point was the response rate in these high-risk patients (90% power to detect a response rate of 50% or higher). The study decision rule requires that 16 or more responses, among 39 eligible patients, are seen in order to declare this treatment effective. Results: Between March 15, 2004 and March 10, 2005, 44 patients enrolled on study. Among the 43 eligible patients, median age was 63; 51% were male. All patients had high risk disease: del 13q (6/41); plasma cell labeling index ≥1% (16/34); and B2M≥5.5 (34/43). Preliminary response data are available for 18 of the 44 cases enrolled, of which 7 had partial response, 1 had minimal response, 1 had no response, 2 had progressive disease, and 5 were unevaluable. Among those patients completing induction therapy and with response information, the median number of cycles of therapy administered is 5, range (0,8). The most common non-hematologic adverse events (AEs) of grade 3 or higher included hyponatremia (9 patients) and diarrhea (6 patients). Mild sensory peripheral neuropathy was common: grade 1, 16 patients; grade 2, 2 patients. Only 1 patient had grade 3 peripheral neuropathy. One patient died after receiving 2 doses bortezomib due to heart block and asystole. Two patients had a grade 4, 25 patients had grade 3, and 13 had grade 1 or 2 as the worst grade non-hematologic adverse event. Based on data received by August 1, 2005, 18 patients have gone off study: AEs (2); death (1); progressive disease (9); and other reasons (6). Updated results on the full study population along with FISH data for IgH translocations and deletions of 13q and 17p will be presented at the meeting. Conclusions: Preliminary results suggest that upfront bortezomib has activity in patients with high-risk MM, but further follow-up is required.

Abstract Abstract 1861 Poster Board I-886 Background: BiRD therapy (clarithromycin/[Biaxin®], lenalidomide/[Revlimid®], dexamethasone) for use as upfront therapy in symptomatic multiple myeloma in 72 patients yielded impressive results: over 90% achieved at least a partial response (PR), with nearly 40% in complete response (CR). We hypothesized that we could safely increase the immunomodulatory benefit of the BiRD combination with the addition of low-dose thalidomide to the regimen, since these drugs have non-overlapping toxicities. A trial of T-BiRD (thalidomide, clarithromycin/[Biaxin®], lenalidomide/[Revlimid®], dexamethasone) therapy for use in up-front treatment of symptomatic multiple myeloma (MM) was initiated to test safety and efficacy. Methods: Eighteen patients were enrolled in a single-institution trial of T-BiRD therapy for symptomatic MM. The T-BiRD regimen consists of clarithromycin 500mg twice daily, dexamethasone on days 1,8,15,22 of a 28-day cycle, and lenalidomide 25mg for days 1–21 of a 28-day cycle. Thalidomide is given at a dose of 50mg daily for the first week and thereafter at 100mg daily. Thromboprophylaxis with aspirin (162 mg once weekly, 81mg on subsequent days) was used for all subjects. Serum protein electrophoresis/immunofixation as well as free light chain determinations were done monthly. Bone marrow biopsy and either skeletal imaging were done at to confirm disease progression or CR. This protocol continues to accrue with a planned enrollment of 25 patients. Results: The median number of T-BiRD cycles was 5.5 (range 1–6). Twelve patients (67%) had achieved at least a partial response (PR) by cycle 1, compared to a median response time of 2 cycles for BiRD. Mean percent drop in M-protein for evaluable patients at each cycle is as follows: Cycle 1 – 61%, Cycle 2 – 77%, Cycle 3 – 79%, Cycle 4 – 81%, Cycle 5 – 93%, Cycle 6 – 92%. For 9 subjects who received 5 cycles of therapy, the overall response rate was 100%, with all but one subject achieving a VGPR or better. On an intent to treat basis, the VGPR or better rate was 55% because of patient withdrawal due to toxicity. A total of 10 subjects (56%) experienced an adverse event (AE), some study-drug related (RAE) during treatment. Seven subjects (39%) withdrew from the study due to drug toxicity: 2 had grade 2 skin rash prior to initiation of full-dose thalidomide (RAE), 1 patient had grade 4 skin rash (Stevens-Johnsons syndrome, SJS) during cycle 1 of T-BiRD (RAE), 1 had a TIA in cycle 2, 1 developed renal failure in cycle 1, 1 developed chest pain in cycle 3. Other toxicities include 1 patient with Grade 2 steroid myopathy (RAE), 1 patient with DVT of the leg (RAE), and 1 patient with atrial fibrillation. 1 subject died of progressive myeloma prior to completion of 1 cycle. Conclusions: T-BiRD is a highly effective first-line regimen for rapid and profound treatment response of multiple myeloma. Toxicity from T-BiRD may preclude its long-term use since many of the enrolled patients experienced an adverse event. Disclosures: Mark: Celgene: Research Funding, Speakers Bureau.

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

Abstract Abstract 2936 Almost all patients (pts) with multiple myeloma eventually relapse and remission duration decreases with each regimen. The median Progression Free Survival (PFS) and Overall Survival (OS) in pts with relapsed myeloma refractory to lenalidomide (len) and bortezomib (btz) is poor at 5 and 9 months respectively. A phase 1 study of len plus btz in pts with relapsed or relapsed, refractory MM (RRMM) demonstrated favorable toxicity and promising response and survival further confirmed in a phase 2 study with len, btz and dexamethasone (dex) [RVD]. In this retrospective study, we assessed the efficacy and toxicity profile of RVD therapy for pts with advanced RRMM. We retrospectively reviewed the records of all pts with RRMM treated with RVD at Princess Margaret Hospital between 03/09 and 05/11. Relapse was defined according to the Uniform International Criteria. Pts were given RVD therapy as previous described by Anderson et al and must have completed at least one cycle of RVD therapy. Primary endpoints were response rate (RR), PFS, OS, and toxicity. Pts discontinued therapy if they experienced PD, no additional benefit or unacceptable toxicity. Definitions of response and progression were used according to the EBMT modified criteria with a category of very good partial response (VGPR). To examine variables independently prognostic for PFS and OS, multivariate Cox analysis was performed. Differences in continuous variables between groups were compared using Mann-Whitney or Kruskal-Wallis tests. Survival curves were constructed according to the Kaplan-Meier method and compared using the log rank test. Thirty pts with RRMM received RVD therapy. Clinical characteristics are seen in Table 1. Median age at RVD initiation was 57 yrs (37–76 yrs), and 46.7% were male. Pts received a median of 3 prior therapies (1–6). In many instances, pts previously treated with len had len added to btz + dex at progression (n=6), or pts previously treated with btz had btz added to len + dex, at progression (n=5). Thalidomide (thal), len and btz containing regimens were previously used in 60%, 73.3% and 80% of pts respectively. PR or better was observed in 46.6%. After a median of 4.6 cycles (1–14), VGPR was seen in 4.8%, PR in 33% and SD in 14%. Pts who achieved PR or better experienced a significant improvement in PFS. There was no difference in terms of RR between those pts according to prior exposure to either btz or len (p=0.7 and 0.9 respectively). Eight pts experienced non-hematological grade 3/4 adverse events (26%), including muscle weakness, sepsis and pneumonia but there was no worsening of peripheral neuropathy. Grade 3–4 neutropenia and/or thrombocytopenia were commonly seen in 70% of pts (n=21). Disease progression was seen in 19 pts at a median of 3.9 months. Median PFS for pts previously exposed to len was 2.3 months vs 2.9 months for those with no prior exposure (p=0.75). On the other hand, median PFS for pts previously exposed to btz was 2.1 months vs 3.4 months for those with no prior exposure (p=0.9) In addition, median PFS for pts who achieved at least PR was significantly better at 5.9 vs 2.0 months for those who did not (p<0.005). (Figure 1) FISH cytogenetics studies were available in 19 out of 30 patients at relapse: 5 -normal, 4–13q deletion, 3-p53 deletion and 2 - t(4, 14). High-risk MM pts had a median PFS significantly lower of 0.6 months (CI 95%, 0–1.99) vs 4.7 months for those without high-risk features (CI 2.5–7.0) (p=0.008) (Figure 2) At the time of submission, 13 pts are alive (43.3%) and 7 pts (23%) continue on RVD therapy.Table 1.Clinical characteristics of patients with RRMM treated with RVDClinical characteristic N=30MedianRange%Age5737-76Male46.7%Female53.3%Hemoglobin (g/L)10571-155Creatinine (mmol/L)99.936-383Beta-2 microglobulin (mmol/L)280119-1440Lactate dehydrogenase (U/L)18189-255IgG56.6% (17)IgA23.3% (7)IgM3.3% (1)Light Chain16.6% (5)Kappa (mg/L)4005.3-346063.3% (19)Lambda (mg/L)5145.1-530036.7% (11)KappaLambda*BMPC57%6-95%M-spike serum (g/L)300-77M-spike urine (g/d)0.890-7.9Prior therapies31-6ASCT83.3% (25)Thal60% (18)Len73.3% (22)Btz80% (24)*BMPC, Bone marrow plasma cells In conclusion, RVD is active and well tolerated in pts with RRMM, including pts who have received prior len, btz, thal and ASCT but PFS is short at 3.9 months in this highly advanced disease group of patients.

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 Pomalidomide is a distinct IMiD® immunomodulatory agent with activity in subjects with relapsed or refractory MM (RRMM), including those with prior lenalidomide treatment. We have previously reported that the addition of clarithromycin enhances the anti-myeloma activity of pomalidomide+dexamethasone (Pom/Dex) in the treatment of RRMM (Mark et al, ASH 2012). We now report updated results with extended follow up from a phase 2 trial of large group of patients treated with ClaPd in RRMM. Methods One hundred nineteen patients with heavily pretreated RRMM were enrolled into a single-institution study to investigate the effectiveness and tolerability of ClaPd. Eligible subjects had at least 3 prior lines of therapy, one line of which must have included lenalidomide. ClaPd is clarithromycin 500mg twice daily; pomalidomide 4mg for days 1-21, and dexamethasone 40mg on days 1,8,15,22 of a 28-day cycle. All subjects had thromboprophylaxis with 81mg aspirin daily. Disease response evaluation was performed monthly with immunoelectrophoresis and free light chain analysis; bone marrow biopsy with skeletal imaging was used to confirm MM progression or complete response (CR). Treatment was continued as tolerated by the patient until disease progression. Results One hundred fourteen patients had completed at least 1 cycle of ClaPd and were eligible for disease response analysis at data cut-off. All patients were included in the safety analysis. Patients had undergone a median of 5 (range 3-15) prior lines of therapy. The proportion of patients who were refractory to lenalidomide, refractory to bortezomib, and double (lenalidomide+bortezomib) refractory were 85%, 79%, and 68% respectively. The median number of ClaPd cycles received was 7 (range 1-34). Overall response rate (ORR, ≥PR, entire cohort/double-refractory subgroup) was 61.4/56.4% [stringent complete remission (sCR): 4.4/4%, complete response (CR): 0.9/1.3%, very good partial response (VGPR): 14.9/11.5%, partial response (PR): 41.2/38.5%, minimal response (MR): 7/9%, stable disease (SD): 21.9/21.8%, progressive disease (PD): 9.6/12.8%, ³VGPR rate of 20.2/16.7%]. Clinical benefit (³ MR) was achieved in 68.4/65.4%. Median time to PR and maximum response was 1 (range 1-7) and 2 (range 1-18) cycles, respectively. After a mean follow up time of 11.9 months, 40 patients (34%) remain free from progression, with a median progression free survival of 8.1 months (95% CI: 5.1, 9.8). Median duration of response (DOR) was 9.3 months (95% CI: 7.2,16.1). Median overall survival (OS) has not been reached with 68 patients (57%) alive at last follow-up. Median PFS, DOR, OS were not significantly different in the double-refractory subgroup at 6.3 (CI 4.7, 8.7; p = 0.21), 8.6 (CI 6.5, 16.1; p = 0.87), and 16.8 months (CI 12.4, 28.7; p = 0.11) respectively. The most common (³% grade 3 and 4 toxicities were: neutropenia (49%), thrombocytopenia (39%), anemia (27%), pneumonia (10%), fatigue 8%, and muscular weakness 7%. Febrile neutropenia was uncommon at 2%. There were 6 cases of lower extremity venous thrombosis (5%, 1 grade 1, 4 grade 2, 1 grade 3) and no instances of pulmonary embolism. Mild peripheral neuropathy was present in 32% (19% grade 1, 13% grade 2), 0% grade 3 or 4). Grade 2 congestive heart failure, due to dexamethasone, emerged in 1 subject (0.8%). Four patients (3.3%) withdrew due to treatment related toxicity (1 with Grade 3 muscular weakness, 2 due to Grade 3 fatigue, 1 grade 4 neutropenic sepsis). There was no treatment related mortality. Conclusions ClaPd is a highly effective and tolerable regimen for heavily treated RRMM that has progressed after prior treatments. Response to ClaPd is rapid and sustained at > 8 months in the majority of subjects. The presence of double refractory disease did not significantly impact clinical outcomes. The ORR and PFS compare favorably and toxicity profile is similar to other published reports of Pom/Dex.
