Abstract Background Lenalidomide is immunomodulatory drug with a range of antineoplastic actions, it is highly effective in multiple myeloma (MM). Lenalidomide has been associated with various adverse side effects including fatigue, constipation, haematological and neurological toxicity. Thyroid dysfunction has been reported as a possible side effect of lenalidomide with incidence 5-10%. Symptoms of thyroid dysfunction can overlap with some side effects of lenalidomide. Thyroid hormone levels are not regularly evaluated in patients (pts) on lenalidomide. Aim In this report we have analysed a cohort of 73 MM pts treated with lenalidomide 25 mg daily (day 1-21, repeating of cycle on day +28) in combination with dexamethasone (160 mg or 320 mg per cycle) and cyclophosphamide 50 mg daily with aims to evaluate efficacy and adverse events of this treatment including of possible occurrance of thyroid impairment. Methods We have prospectively evaluated 73 pts with the first relapse of MM who received lenalidomide as a part of the second-line treatment between 2008 and 2012, median follow-up from start of treatment was 24 months (range 2-46), median age was 65 years. Median number of cycles was 6 (range 4-10). Thyroid function tests were checked in regular 2-month intervals from the start to the end of lenalidomide treatment - thyroid stimulating hormone (TSH) and free thyroxine (FT4). Results Overall response rate (ORR) was 53% (39/73), 10% (7/73) of pts were in complete remission (CR), very good partial response (VGPR) was achieved in 18% of pts (13/73), partial response (PR) in 25% of pts (19/73), minimal response (MR) or stable disease (SD) in 10% of pts (7/73), progression was observed in 37% of pts (27/73). Median time to progression (TTP) and overall survival (OS) from start of lenalidomide treatment were 18.4 and 29.6 months, respectively. Adverse events (AE) in time of lenalidomide treatment were frequent, but mostly grade 1 or 2. The most frequent AE were as follows: anemia (77%), neutropenia (67%), thrombocytopenia (54%), neuropathy (38%), fatigue (65%), infections (49%) and gastrointestinal toxicity (21%). Grade 3 or 4 adverse events included neuropathy (5%), thrombosis (4%), infections (15%), thrombocytopenia (10%), neutropenia (27%) and fatigue (6%). Previous diagnosis of thyroid dysfunction was presented in four MM pts (5%). New thyroid abnormalities grade 2 were developed on lenalidomide treatment in seven pts (10%). Hypothyreosis was presented in five pts, hyperthyreosis in two pts. Treatment of thyroid dysfunction was necesarry in all seven pts. Median time to occurrance of thyroid dysfunction was 4 months (range 2-8 months). Conclusion Lenalidomide is effective treatment for the first relapse of MM with ORR 53%, but lenalidomide can cause various adverse events and significant thyroid abnormalities. Regular routine monitoring of TSH could be recommended in MM patients treated with lenalidomide. Treatment of symptomatic thyroid dysfunction can improve the quality of life for patiens undergoing lenalidomide treatment. Disclosures: No relevant conflicts of interest to declare.

Original versus generic lenalidomide in patients with relapsed multipl myeloma: Comprasion of effectivity and adverse events Ali Zahit Bolaman1, Sehmus Ertop2 Atakan Turgutkaya1, Cem Selim, 1 Ayse Hilal Eroglu Kucukerdiler1, Birsen Sahip2, Irfan Yavasoglu1. 1 Adnan Menderes University, School of Medicine, Department of Hematology AYDIN/TURKEY 2 Bulent Ecevit University School of Medicine, Department of Hematology ZONGULDAK/TURKEY Backround: Lenalidomide is an effective IMID derivative drug in the treatment of patients with multiple myeloma. Lenalidomide is available as original and generic forms in our country. So far, there is no any clinical study comparing generic and original lenalidomine for effectivity and adverse events. We compared generic and original lenalidomide effects and adverse events (AEs) in patients with relapsed multiple myeloma (RMM). Methods: The patients with RMM using original or generic lenalidomide were evaluated as retrospectively. Overall response (OR), complete response (CR), very good partial response (VGPR), partial response (PR), stable disease and progressive disease rates and also for adverse events, development rates of neutropenia, anemia, thrombocytopenia, febrile neutropenia, anorexia, constipation diarrhea, nausea, vomiting, creatinine increase, transaminase increase, asthenia, fatigue, pyrexia, peripheral edema, upper respiratory system infection, pneumonia, another infection, muscle cramp, back pain, bone pain, muscle weakness, arthralgia, headache, tremor, paresthesia, deep vein thrombosis, pulmonary embolism, hyperglycemia, hypokalemia, hypocalcemia, hypomagnesaemia, skin dry and skin erythema were investigated in myeloma patients. All data were analyzed using the PASW for Windows version 19.0 (SPSS Inc., Chicago, IL, USA). The results were described as a number, frequency, and percentage. The chi-squared test and Fisher's exact test were used for the analysis of categorical data and independence between variables. The results were assessed at 95% confidence interval and p-value of less than 0.05 was accepted as significant. Results: The number of patients using original lenalidomide was 55 and the number of patients using generic lenalidomide was 43. OR rate was 60 % versus 39.5% in patients using original and generic lenalidomide, respectively. CR rate was 14.5%, VGPR was rate 45.4% in original group while CR rate was 20.9 and VGPR 18.6 in patients using generic lenalidomide. AEs were low in original lenalidomide group than generic group. AEs were usually grade 1 or 2. Response and AEs rates are shown in Table 1. Conclusion: Our study showed original and generic forms of lenalidomide are effective for the treatment of RMM. OR rate was higher in original lenalidomide than generic lenalidomide. The AEs of original lenalidomide were lower than generic lenalidomide without statistically significance. Further studies involving a larger number of patients with RMM would be useful for comparing the efficacy and AEs of original or generic lenalidomide.

Abstract Object: To investigate the short-term and long-term efficacy and toxicity of pegylated liposomal doxorubicin, vincristine and dexamethasone (DVD) in patients with newly diagnosed multiple myeloma (MM). Methods: Twenty-five patients (13 males, 12 females, median age 55 years) with newly diagnosed multiple myeloma were treated with pegylated liposomal doxorubicin 40 mg/m2 and vincristine 2 mg intravenously on day 1 plus dexamethasone 40 mg intravenously or orally on days 1–4 (DVD) for median 4.5 (2–8) cycles. Treatment was repeated every 4 weeks. Response was evaluated according to the International Uniform Response Criteria for Multiple Myeloma (2006) before initiation of each course. Adverse events were graded according to the National Cancer Institute Common Toxicity Criteria, version 3.0. Results: After 4.5 (2–8) courses of the median cycles, clinical response was observed in 20 patients (80%), including complete response in 4 (16%), very good partial response in 3 (12%), partial response in 10 (40%), minimal response in 3 (12%) and stable disease in 2 (8%). The median time to initial response was 1.2 months and the median time to best response was 4 months. After 25 (2–50) months of median follow-up, the median progression-free survival was 20 months, while the median overall survival has not yet been reached. The overall survival rate was 72% (18/25). The most common adverse events were gastrointestinal symptoms (nausea and vomiting in 10, constipation in 9 patients), neutropenia (7 patients), anemia (6 patients) and thrombocytopenia (4 patients). DVD was associated with more hand-foot syndrome (4 patients) and mucitis (2 patients). Conclusions: DVD scheme is an effective therapy with a high response rate and manageable toxicities for patients with newly diagnosed multiple myeloma.

Abstract Abstract 1868 Backgrounds & Aims: Salvage therapy such as bortezomib, cyclophosphamide, thalidomide and dexamethasone (Vel-CTD) showed an effective regimen in patients with relapsed or refractory multiple myeloma (MM). However, toxicities of this regimen due to combination bortezomib and thalidomide interrupt the consecutive treatments in a few patients. Therefore, we compared the clinical responses and toxicities between bortezomib, cyclophosphamide and dexamethasone (Vel-CD) and Vel-CTD in patients with relapsed or refractory MM patients, retrospectively. Methods: Eighty-six patients received at least 2 cycles of treatment with Vel-CTD (bortezomib 1.3 mg/m2 i.v. on D1, 4, 8 and 11; cyclophosphamide 150 mg/m2 orally on D1-4; thalidomide 50 mg/day orally every day; and dexamethasone 20 mg/m2 i.v. on D1, 4, 8 and 11 for every 3 weeks) and 67 patients with Vel-CD, which is the same regimen except thalidomide. Vel-CD group was only received low-dose acyclovir for prevention of herpes zoster. Results: 17/67 (25%) and 10/86 (12%) of light chain disease was enrolled in Vel-CD and Vel-CTD group respectively (p=0.027) and there was no statistical difference at baseline demographic and disease characteristics between two groups in the others. The median time from diagnosis to treatment in Vel-CD and Vel-CTD was 15.6 months (range, 2–250 months) and 15.7 months (range, 1–230 months), respectively (p=0.54). The median number of treatment cycles was 6 cycles (range, 2–18) in Vel-CD and 8 cycles (range, 2–24) in Vel CTD group, and the number of cycles delivered was 430 and 678, respectively. The overall response rates (≥PR) of Vel-CD and Vel-CTD group were 88% and 90% ( 49% and 48% of complete response, 9% and 14% of very good partial response, 30% and 28% of partial response), respectively (each, p>0.05). There was no difference in progression free survival (p=0.69) and overall survival (p=0.49). Grade 3 or more hematologic adverse events occurred in the same proportion of patients in the both group. In non hematologic toxicities profiles, Vel-CTD group (14%) showed the higher proportion of grade 3 or more sensory neuropathy compared with Vel-CD group (3%) (p=0.02). Dose adjustment of bortezomib in Vel-CD and Vel-CTD were 40% (27/67) and 41%(35/86), respectively (p=0.96). Two patients (3%) in Vel-CD group received acyclovir prophylaxis developed herpes zoster compared with 17 patients (20%) in Vel-CTD group they were not received acyclovir prophylaxis (p=0.002). Three patients showed thrombotic events (2: pulmonary thromboembolism, 1: acute myocardial infarction) in only Vel-CTD group despite aspirin prophylaxis (p=0.16). Conclusion: Vel-CD combination therapy in patients with relapsed or refractory MM is an effective and more tolerable salvage regimen compared with Vel-CTD in the aspect of comparable response rate, less non-hematologic toxicities especially thalidomide associated adverse events.

Abstract Abstract 1875 Poster Board I-900 Study purpose: To explore how free light chain (FLC) removal by high cut-off haemodialysis (HCO-HD) has been adopted into clinical practice for the management of renal failure secondary to multiple myeloma. Describing treatment patterns and the laboratory and clinical outcomes associated with its use. Methods: A chart audit of patients treated with FLC removal by HCO-HD, using the Gambro HCO 1100 dialyser, was performed in 16 dialysis centers across 9 countries. Patient demographics, treatment patterns and dialysis side-effects were recorded. In addition, the following outcomes were measured: dialysis independence and reductions in serum FLCs concentrations at 12 and 21 days. Results: Data for 66 patients was entered. Patients had an average age of 65.1 (SD×10.1); 42 of them (63.64%) were male and 24 (36.36%) were female. Sixteen (24%) presented with relapsing myeloma and 50 (76%) had de novo disease. On average, each patient received 13 HCO-HD sessions (SD×8). Forty-one patients became dialysis independent (62.12%), after an average of 12 sessions. Dialysis related side-effects were reported in 6% of all patients. Forty patients (60.61%) were reported to have a sustained reduction in serum FLC concentrations by day 12. By day 21 this had increased to forty-one (62.12%). Among the patients who achieved a sustained reduction in serum FLC concentrations, 28 (70%) had a decline in FLC levels of more than 50% by day 12 and 34 (82.93%) by day 21. Among patients who achieved sustained reduction of more than 50% in serum FLC concentrations by day 12, 75% became dialysis independent. In comparison only 53% of those with a reduction of less than 50% became dialysis independent (p×0.007). Furthermore, among patients who achieved sustained FLC reduction of greater than 75%, 81% became dialysis independent. The rate of dialysis independence was also significantly higher in patients with de novo disease compared with those with relapsing myeloma (64% versus 56%, p×0.04). Conclusion: Free light chain removal by HCO-HD was well tolerated and associated with a very high rate of dialysis independence in patients with renal failure secondary to multiple myeloma. Rates of renal recovery were greater in patients with de novo myeloma and those who achieved an early reduction in serum FLC concentrations.

Abstract Abstract 4940 Introduction Many physicians have anecdotally reported that Asian patients with multiple myeloma (MM) are frequently unable to tolerate full doses of dexamethasone (Dex) and/or thalidomide (Thal). Unfortunately, co-operative clinical studies from the Asia-Pacific countries are presently lacking and the effective dose of the Dex/Thal combination in Asians is unknown. Since higher doses of zoledronic acid (Zol) have been shown to exert an anti-MM effect in pre-clinical models of MM, we investigated whether higher frequency dosing of Zol combined with lower doses of Dex/Thal could be an effective and better tolerated regimen in Asian patients. Moreover, since attainment of very good partial response (VGPR), near complete response (nCR) or complete response (CR) prior to autologous hematopoietic stem cell transplantation (AHSCT) correlates with good outcome in MM, we wanted to determine if this lower-dose Dex/Thal with higher-frequency dosing Zol regimen could be a good preparative regimen in transplant-eligible patients. Patients and Methods In this international co-operative multicenter phase II non-randomized single arm study in previously untreated patients with MM (n=44), all patients received up to 6 cycles of three-weekly Dex/Thal/Zol (or “dtZ”). Doses of Dex ranged from 20 mg weekly to 20 mg four times a week; and doses of Thal ranged from 50 mg weekly to 100 mg every night. Zol 4 mg was given three-weekly. Response was graded using Blade's criteria. Results The study population included 67.3% Oriental (Korean and Chinese), 30.8% Indian and 1.9% Malay patients. 15.4% of patients were ISS stage I, 61.5% stage II and 23.1% stage III prior to treatment. 39 (88.6%) patients demonstrated at least a partial response (PR); and 23 (52.3%) of patients achieved VGPR (18.2%), near nCR (15.9%) or CR (18.2%). The fastest time to VGPR/nCR/CR was 1 cycle. Most patients tolerated treatment very well and were managed in the outpatient clinic. Sepsis was the most frequently reported grade 3 or 4 toxicity – 8 (18.2%) patients developed bronchopneumonia, and 3 (6.8%) gastrointestinal or urinary tract infections. 1 (2.3%) patient was suspected of having pulmonary embolism. There were 4 (9.1%) deaths – 3 from severe sepsis and 1 from an unknown cause. Importantly, there were no reports of peripheral neuropathy, osteonecrosis of the jaw (ONJ) or end stage renal failure. In fact, there was an overall 2.4% improvement in the median creatinine clearance time (CCT). Finally, the percentage of CD34 stem cells was not adversely affected by treatment with dtZ. Conclusions The dtZ regimen appears to be an effective and well-tolerated treatment regimen for Asian patients with newly-diagnosed MM. The high rate of VGPR/nCR/CR will greatly facilitate AHSCT in transplant-eligible patients. Judicious use of low-dose Thal has abrogated the numerous side-effects associated with Thal and greatly improved patient tolerance. Even though Zol is administered at a higher frequency, it is not associated with worsening of renal function or ONJ. Infections are the most frequent and worrisome complications of treatment. These are likely to be related to the dose of Dex. Accordingly, it is probably wise to further lower the dose of Dex in future studies. (This study is registered with NIH PRS # 00263484.)

Abstract Abstract 4952 Background Current clinical observations on extramedullary myeloma (EM) are based on small series of relapsed myeloma patients (pts) and, in this situation, results suggest that the disease course is often aggressive. Among novel therapies for extramedullary involvement, thalidomide has provided poor results and bortezomib is emerging as a possible useful drug. The role of lenalidomide for treatment of multiple myeloma (MM) with EM is still under investigation. Aim A multicenter retrospective study was performed by PETHEMA (Spanish Myeloma Group, Spain) to evaluate the response rate and toxicity profile of lenalidomide-based regimens in myeloma patients with extramedullary involvement at relapse or progression. All the cases were evaluated for response of MM and improvement of extramedullary plasmacytoma. Patients and Methods From October 2007 to March 2009, thirteen patients (median age 67 years; range 61–87; 7 females) treated with lenalidomide-containing regimens were recorded. Patients with bone disease without extramedullary manifestations were excluded. Response of MM was evaluated according to the new international criteria and the response of EM by measuring size changes by physical examination, CT scans and/or MR imaging. Adverse events were graded based on the WHO toxicity scale. The M-protein type was IgG in 7 cases, IgA in 5 and light chain in 1. The type of light chain was κ in 7 pts and l in 6. In eight patients the soft-tissue plasmacytomas may have developed from underlying bone lesions [(skull (n=2), rib cage (n=4) and paravertebral (n=2)], two patients had subcutaneous nodules and three had visceral involvement (liver (n=1), lung and kidney (n=1) and pleura (n=1). Multiple localizations were present in 4 pts (30.7%). Six cases (79.6%) received previous antimyeloma treatment for EM before lenalidomide therapy and the incidence of prior bone plasmacytomas was 61.5%. Median time from initial antimyeloma therapy to treatment with lenalidomide was 34 months (range 5 - 115). Median number of prior lines of chemotherapy regimens was 3 (range 1 – 4), including autologous stem cell transplantation in 2 pts, bortezomib-containing regimens in 12 (92.3%) and previous exposure to thalidomide in 1 patient. Ten pts received standard lenalidomide dose (25 mg/day every 4 weeks) plus dexamethasone (40 mg/d PO ranging from 1 to 12 doses/cycle) every 3-week; and three patients received lower doses of lenalidomide and/or different schedules. Involved-field radiotherapy was given in 2 cases. Thirty percent of patients required lenalidomide dose reduction, because of toxicity or intolerance. Results Median duration of lenalidomide treatment was 3.6 months (1 – 15). One case was not evaluable for response because of death from disease progression after one cycle. In nine out of twelve evaluable patients (75%), MM responded to lenalidomide regimens according to EBMT criteria. Three (25%) achieved complete response, five (41.6%) partial response and 1 (8.3%) minimal response. Median time to response was 63 days (range 37 – 180). Regarding EM, nine patients showed response in the size of extramedullary plasmacytomas. Seven (58.3%) achieved complete disappearance of EM and two pts reduction of the size. Response of EM was also achieved in 75% of pts previously exposed to bortezomib, and in 4/9 cases who received therapies for prior extramedullary involvement. Median follow-up period was 6.3 months (1 – 15.8). Median overall survival from the start of lenalidomide therapy was 4.7 months. At the time of analysis, seven patients were still on therapy, and ten (76.9%) were alive. Only one out of the 9 patients who had achieved a response has relapsed so far. Toxicity profile (grade 3/4) was: thrombocytopenia, 4 (30.7%); anemia, 2 (15.3%); neutropenia, 5 (46.4%); neutropenic fever, 1 (7.6%) and others, 3 (11.8%). No deep venous thrombosis (DVT) was reported. Thrombosis prophylaxis was used in most cases (92%) patients. Conclusions We report one of the first investigations specifically evaluating the activity of lenalidomide on EM. Lenalidomide-containing regimens could be an alternative promising approach to achieve clinical response in heavily treated MM patients with extramedullary disease. The duration of response and the best regimen or combination are at present unknown. These preliminary observations require further analysis and longer follow-up.

Abstract Abstract 4947 Background Recent advances in the treatment of multiple myeloma (MM) have significantly improved overall survival. With MM patients living longer, there is a constant need to find better therapeutic options, especially when patients are refractory to conventional agents, and are not eligible for experimental therapeutics in clinical trials. We evaluated treatment with single-agent high-dose cyclophosphamide (HDCy) in a cohort of heavily pre-treated patients with relapsed/refractory MM. Methods All the patients were previously treated for active MM at the University of Southern California (USC), Los Angeles, CA. Cyclophosphamide was administered at 1.2 gm/m2 in D5W intravenous (IV) over 1 hour every 3 hours for a total of 4 doses. Mesna was given to prevent urinary adverse events from cyclophosphamide as 4 gm/m2 in 1000 ml D5W IV to run at 50 ml/hr for 20 hours, starting 15 minutes prior to the first dose of cyclophosphamide. Patients were given pre-medications with 5HT3 antagonists an steroids. Treatment was administered in the in-patient setting and patients were discharged after the last dose of cyclophosphamide. Treatment was repeated every 4 weeks, if well-tolerated and continued response. Growth factor support was provided to the patients, as needed. Response to treatment was assessed after each 4-week cycle according to the International Uniform Response Criteria for MM. Results Seven patients (4 females, 3 males) were treated on this regimen with a median age of 53 years (range 34-61 yrs). These patients included 3 Hispanics (43%), 2 Asians (29%), 1 Caucasian (14%) and 1 African-American (14%). MM subtype was IgG disease in 3, IgA in 2, and light-chain only in 2 patients. Advanced stage disease (>stage 1) at the time of diagnosis as per the Durie Salmon (DS) staging system was present in 71% of the patients, while 3 patients (43%) had advanced stage disease as per the International Staging System (ISS). Four patients (57%) had lytic bone disease at the time of diagnosis, while only 1 patient was a non-secretor. Five of these patients (71%) never received an autologous stem cell transplant (ASCT) as a part of their MM treatment. Median number of therapies in these patients was 5 (range 4-8), while median number of therapies prior to high-dose cyclophosphamide (HDCy) were 3 (range 2-7). Median number of cycles of HDCy administered to the patients was 2 (range 1-5). Overall Response Rate (ORR = CR+PR) was 29% (n=2) with 1 patient achieving CR and 1 patient achieving VGPR. Four patients (57%) had stable disease (SD) and 1 patient had progressive disease (PD). Thus, the overall clinical benefit (CR+PR+SD) was seen in 6 out of the 7 patients (86%). Median time to best response was 5 weeks (range 4-10 weeks). Median time to progression was 16 weeks (range 8-24 weeks). Most common adverse events were cytopenias and fatigue, but were easily manageable with supportive care on an out-patient basis. Conclusions Despite improvement in therapeutic regimens for MM, it remains an incurable disorder. There is a constant need to develop regimens for treatment of relapsed/refractory MM patients that are efficacious and well-tolerated. We report the use of single-agent HDCy in heavily pre-treated MM patients. Despite the small number of patients studied, we have noted meaningful clinical benefit with a manageable toxicity profile. This warrants further investigation into developing therapeutic regimens with high-dose cyclophosphamide. Disclosures No relevant conflicts of interest to declare.

Abstract Abstract 5124 Introduction: Novel agents like the proteasome inhibitor bortezomib (Btz) and immunomodulatory agents show activity in multiple myeloma (MM) as well as in primary AL amyloidosis (AL). Btz has emerged as a standard of care in the treatment of patients with MM and AL. The approved dose and schedule of Btz is 1.3mg/m2 administered on days 1, 4, 8, and 11 as an intravenous (i.v.) bolus injection. However, among several side effects, peripheral neuropathy (PN) has a particular negative impact on the quality of life of patients treated with Btz. A recent trial provided evidence for a similar efficacy of Btz administered subcutaneously (s.c.) compared to i.v. administration, but side effects including PN were significantly less frequent with s.c. application of Btz. Here we report our experience regarding efficacy and tolerability of treatment with Btz administered s.c. in patients with MM and AL. Patients and Methods: 19 consecutive patients with MM (n = 17) or histologically proven AL (n = 2) were included in this analysis. For s.c. administration, Btz was prepared at a concentration of 2.5 mg/mL (as opposed to an i.v. concentration of 1.0 mg/mL). All patients received Btz at a dose of 1.3 mg/m2 on days 1, 4, 8, and 11. Btz was used in combination regimens with dexamethasone (n = 9), with thalidomide/dexamethasone prior to autologous transplantation (VDT; n = 6), or with melphalan/prednisolone in elderly patients (VMP; n = 4). Results: Patients (male n=7; female n=12) were at a median age of 64 years (range 38–77), and 11 patients (58%) received the Btz-based regimen with Btz s.c. as their first line treatment. At the time of analysis, a median of 3 cycles bortezomib s.c. (range, 1–5) have been administered. Hematological toxicities were only at Grades 1+2 and included anemia (78%) and thrombocytopenia (33%). Only one patient developed a grade 3 PN, and this patient already had pre-existing PN due to prior i.v. administration of Btz. Other non-hematologic side effects were at grades 1+2 including fatigue (11%) and local skin reactions at the site of s.c. injection, which were self-limited. No notable gastrointestinal toxicity was observed, and therefore we stopped the routine use of i.v. hydration and antiemetics, which were previously administered as concomitant therapy with i.v. Btz. Of 14 MM patients so far evaluable for response, 12 (86%) had a PR or better including 5 patients (36%) achieving a CR. Both patients with AL achieved a very good partial remission (VGPR). More data on efficacy with longer follow-up will be presented at the meeting. Conclusion: Our observations confirm the improved toxicity profile of the s.c. administration of Btz in various standard Btz-based combination regimens. In addition, due to the ease of s.c. administration of Btz, patient management has been markedly facilitated at our centre. Disclosures: No relevant conflicts of interest to declare.

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 Abstract 5036 Objective: To assess the efficacy and tolerability of bortezomib with dexamethasone for patients with primary systemic light chain (AL) amyloidosis or multiple myeloma-associated AL amyloidosis. Methods: Twelve newly diagnosed patients with primary systemic AL amyloidosis and six patient with multiple myeloma-associated AL amyloidosis were treated with a combination of bortezomib (1. 3 mg/m2 d1, 4, 8, 11) and dexamethasone (20 mg d1–4). Results: Sixteen patients was evaluable. 12/16 had a hematologic response and 6/16 (37. 5%) a hematologic complete response. Median cycles to response was 1 cycle and median cycles to best response was 2 cycles. In patients with primary AL amyloidosis, 8/10 (80. 0%) had a hematologic response and 5/10 (50. 0%) a hematologic complete response. In patients with myeloma-associated AL amyloidosis, 7/10 (70. 0%) had a hematologic response and 1/6 (16. 7%) a hematologic complete response. Twelve patients (75. 0%) had a response in at least one affected organ, in which 7 in patients with primary AL amyloidosis and 5 in myeloma-associated AL amyloidosis. Person correlation between hematologic response and organ response was 0. 667 (p=0. 005). Fatigue, diarrhea and infection were the most frequent side effects. Three patients developed herpes zoster and had to stop chemotherapy. Conclusions: VD produces rapid and high hematological responses in the majority of patients with newly diagnosed AL regardless of primary or associated with myeloma. It is well tolerated with few side effects. This treatment may be a valid option as first-line treatment for newly diagnosed patients with primary systemic AL amyloidosis and multiple myeloma-associated AL amyloidosis.
