Abstract Background: Bortezomib is an effective treatment for patients with relapsed multiple myeloma with an overall response rate (≥PR) of 43% and time to progression of 6.2 months (APEX study). We and others have previously demonstrated potent in-vitro synergy with chemotherapeutic agents such as melphalan and it is likely that this will translate into improved responses in the clinical setting. Methods: This was a multi-centre, non-randomised Phase I/II clinical trial for patients with relapsed multiple myeloma. Bortezomib 1.3mg/m2 was given on Days 1,4,8 and 11 of a 28 day cycle, and intravenous melphalan on Day 2 for a maximum of 8 cycles. In the Phase I component melphalan was given at 2.5, 5,7.5 and 10mg/m2 in a dose escalation scheme and the maximum tolerated dose (MTD) of 7.5mg/m2 was taken forward to an expanded Phase II component. Dexamethasone 20mg on the day of and the day after each dose of bortezomib was permitted for progressive or stable disease after 2 or 4 cycles respectively. Responses were defined by EBMT criteria. Results: 53 patients were enrolled (median age 61years [range 40–77]) with a median of 3 lines of prior therapy [range 1–5] of which 26 (67%) have had one previous autologous stem cell procedure and 4 (10%) have had two. 23 (59%) have had prior exposure to thalidomide and 4 (10%) to bortezomib. The overall response rate (≥PR) across all treatment levels (n=52) was 65% rising to 69% (CR 19%; nCR 4%; VGPR 6%; PR 40%; MR 15%) with the addition of dexamethasone in 27 cases for suboptimal response. Of the 32 patients treated at the MTD the overall response rate (≥PR) was 78% (CR 28%; nCR 6%; VGPR 6%; PR 38%; MR 9%). Rapid responses were seen with the median time to response being 1 month [range 1–6]. The median time to progression was 10 months and the median overall survival has not yet been reached at a median follow-up of 17 months. Of the patients that have had disease progression 7 (35%) had responses of longer duration than their previous therapy. The MTD was defined by unacceptable delays in administering treatment due to myelosuppresion. The toxicities have been acceptable with 13 SAEs reported of which 8 were hospitalisation due to infection. The most common grade 3–4 adverse events were: thrombocytopenia (53%), infections (25%), neutropenia (17%) and neuropathy (17%). Three grade 3 cardiac events were seen (myocardial infarction, atrial fibrillation and cardiac failure) and GCSF was administered to 13 patients as treatment and prophylaxis of grade 4 neutropenia. 19 patients were withdrawn from the study due to toxicity of which 7 were for neuropathy and 3 for delayed haematological recovery. Of note, 11 patients (28%) had pre-existing grade 1 neuropathy prior to starting therapy. Summary: The combination of bortezomib, low dose intravenous melphalan and dexamethasone appears to be highly effective in patients with relapsed multiple myeloma with a response rate (≥PR) at the MTD of 78% including 34% nCR/CR. The toxicity profile is predominantly haematological.

Abstract Background: Bortezomib is an effective treatment for patients with relapsed multiple myeloma with an overall response rate (MR+PR+CR) of 46% and time to progression of 6.2 months (APEX study). We and others have previously demonstrated potent in-vitro synergy with chemotherapeutic agents such as melphalan and it is likely that this will translate into improved responses in the clinical setting. Methods: This was a multi-centre, non-randomised Phase I/II clinical trial for patients with relapsed multiple myeloma. Bortezomib 1.3mg/m2 was given on Days 1,4,8 and 11 of a 28 day cycle, and intravenous melphalan on Day 2 for a maximum of 8 cycles. In the Phase I component melphalan was given at 2.5, 5,7.5 and 10mg/m2 in a dose escalation scheme and the maximum tolerated dose (MTD) of 7.5mg/m2 was taken forward to an expanded Phase II component. Dexamethasone 20mg on the day of and the day after each dose of bortezomib was permitted for progressive or stable disease after 2 or 4 cycles respectively. Responses were classified by EBMT criteria. Results: To date 39 patients have been enrolled (median age 61years [range 40–77]) with a median of 3 lines of prior therapy [range 1–5] of which 26 (67%) have had one previous autologous stem cell procedure and 4 (10%) have had two. 23 (59%) have had prior exposure to thalidomide and 4 (10%) to bortezomib. 36 have now completed at least 1 cycle and are therefore evaluable for response. The overall response rate (CR+PR+MR) across all treatment levels was 75% rising to 81% (CR 11%; nCR 3%; VGPR 8%; PR 39%; MR 19%) with the addition of dexamethasone in 13 cases for suboptimal response. Rapid responses were seen with the median time to response being 1 month [range 1–6]. The median time to progression is 10.1 months and the median overall survival has not yet been reached at a median follow-up of 7.4 months. Of the patients that have had disease progression 7 (35%) had responses of longer duration than their previous therapy. The MTD was defined by unacceptable delays in administering treatment due to myelosuppresion. The toxicities have been acceptable with 13 SAEs reported of which 8 were hospitalisation due to infection. The most common grade 3–4 adverse events were: thrombocytopenia (53%), infections (25%), neutropenia (17%) and neuropathy (17%). Three grade 3 cardiac events were seen (myocardial infarction, atrial fibrillation and cardiac failure) and GCSF was administered to 13 patients as treatment and prophylaxis of grade 4 neutropenia. 13 patients were withdrawn from the study due to toxicity of which 7 were for neuropathy and 3 for delayed haematological recovery. Of note, 11 patients (28%) had pre-existing grade 1 neuropathy prior to starting therapy. Summary: The combination of bortezomib, low dose intravenous melphalan and dexamethasone appears to be highly effective in patients with relapsed multiple myeloma where a response rate of 81% is seen with 14% achieving nCR/CR. The toxicity profile associated is predictable, manageable and predominantly haematological. Recruitment is ongoing to a total of 53 patients.

Abstract Background: Bortezomib as a single agent has known efficacy in the treatment of relapsed multiple myeloma. The overall response rate (CR+PR+MR) was 35% in the SUMMIT study and 46% in the APEX study. In-vitro studies including our own have demonstrated potent synergy with other chemotherapeutic agents such as melphalan. It therefore follows that responses to bortezomib may be further improved by the combination of such drugs. Aims: The primary objectives of this Phase I/II study was to assess the safety, tolerability and response rates in patients with relapsed multiple myeloma; secondary objectives being time to progression (TTP) and overall surival (OS). Methods: This was a multi-centre, non-randomised trial for patients with relapsed myeloma. Patients received bortezomib 1.3mg/m2 on days 1,4,8 and 11 of each 28 day cycle with melphalan on day 2 at increasing dose levels. This was initially at 10mg/m2, but due to cytopenias subsequently at 2.5 and 5mg/m2 (levels 1a, 1 and 2) and we plan to escalate to 7.5mg/m2. Up to 8 cycles were given with dexamethasone added for stable or progressive disease after 4 or 2 cycles respectively. Responses were determined by EBMT criteria. Results: To date, 18 patients have been enrolled (12 male 6 female; median age 60 [range 44–73]; median number of prior therapies 3 [range 1–5] of which 17 have had at least one autologous stem cell procedure with high dose melphalan; 10 prior thalidomide and 2 prior bortezomib). 12 patients received melphalan at 10mg/m2 but due to unacceptable delays predominantly due to thrombocytopaenia, subsequent treatment levels commenced at 2.5mg/m2. The median number of cycles completed thus far is 4 (range 0–8) and of the 16 evaluable, the overall response rate (CR+PR+MR) across all treatment levels was 50% rising to 75% following the addition of dexamethasone as per protocol. At level 1a (melphalan 10mg/m2 ,N=12, median number of cycles completed =5) the best responses (with dexamethasone as indicated) were: 1CR, 1 VGPR, 5 PR, 2 MR; at level 1 (melphalan 2.5mg/m2, N=4) 1 PR, 2 MR (after 2 cycles only). The median time to any response was 1 cycle (range 1–3 ). Three patients have progressive disease, but the median TTP and OS have not yet been reached (median follow-up 3 months). Non-haematological toxicities have been modest with 7 SAEs reported of which only 1 was possibly drug related (myocardial infarction), and 4 episodes of Grade 3 neuropathy (2 resulting in study withdrawal). The commonest grade 3–4 haematological toxicity was thrombocytopaenia (N=10) complicated by bleeding in one patient, followed by neutropenia (N=6). Summary: The combination of bortezomib and intravenous melphalan can be given safely to patients with relapsed multiple myeloma and dose escalation is ongoing. Myelosupression was the commonest grade 3–4 adverse event. A response rate of 50% was seen, which was further improved to 75% with the addition of dexamethasone. This combination may therefore result in higher responses than single agent bortezomib in heavily pretreated patients.

Abstract Abstract 1851 Background: Bendamustine, an agent sharing properties of alkylators and purine analogous, showed a strong efficacy and safe toxicity profile in relapsed multiple myeloma (MM) patients (pts), with a maximally tolerated dose (MTD) ranging from 100 mg/m2/die day 1 and 2 as single agent to 60 mg/m2/die in association with thalidomide. In a pooled analysis of two large phase 3 trials Lenalidomide, an analogous of thalidomide with strong activities in MM, significantly improved overall response rate and progression-free survival. Since the role of Lenalidomide in the treatment of naïve and relapsed/refractory pts has been well established, the current research is focused on the combination of Lenalidomide with chemotherapy to further improve patient outcome. Methods: This multicenter phase I/II trial was designed to investigate the combination of Bendamustine, Lenalidomide, and Dexamethasone (BdL) in repeating 4-week cycles as treatment for relapsed MM. Pts over 18 years with measurable stage II or III MM who relapsed after 1 to 3 previous lines of therapy, including bone marrow transplantation were considered eligible. Prior Lenalidomide and Bortezomib were allowed. The phase I study was conducted using a 3+3 cohort design beginning at a dose level 0 of intravenous Bendamustine 40 mg/m2/die days 1 and 2, oral Lenalidomide 10 mg/die days 1–21 and oral Dexamethasone 40 mg/die days 1, 8, 15, and 22 (28-day cycle). The dose of Bendamustine and Lenalidomide (from 0 to 5) were increased from one cohort to the next, in a 3+3 dose escalation scheme to reach the MTD (Table 1). The MTD of Bendamustine and Lenalidomide were evaluated during the first treatment course (cycle 1). Enrollment at each subsequent dose level was permitted only if the first 3 patients at the previous level received 1 cycle with an acceptable dose-limiting toxicity (DLT). DLTs were defined as any adverse event (AE) possibly related to the study drug ≥grade 3 CTC. If 1 of the 3 subjects experienced DLT during the first cycle, 3 more subjects were to be recruited and treated at the same dose level of Bendamustine and Lenalidomide. Treatment was given until plateau of best response according to the International Myeloma Working Group uniform response criteria for a maximum of 6 cycles. Results: Herein, we present the results from phase I of the study which established MTD. Fifteen pts with a median age of 69 years (range 49 to 88) were enrolled between October 2011 and February 2012. The number of prior therapies was at maximum 3 as per protocol: Lenalidomide (27% of pts), thalidomide (33% of pts), Bortezomib (67% of pts) and 13% of the pts had a prior autologous stem cell transplant. Because 3 DTL were observed in Phase I, the MTD was set at 40 mg/m2/die for Bendamustine and 10 mg/die for Lenalidomide. DLTs at dose level 1 included: 1 grade 4 cutaneous rash; at dose level 2: 1 grade 4 thrombocytopenia and 1 grade 3 bronchopneumonia with renal dysfunction (Table 2). Among the 15 patients with evaluable data, the grade 3 or 4 AEs observed in ≥10% of patients included neutropenia (20%), thrombocytopenia (13%) and anemia (20%). Two patients died of treatment-related complications: 1 for hematological toxicity and CNS hemorrhage, and 1 for cardiac ischemia. Fifteen patients received at least 2 cycles and were included in the response assessment. The overall response rate was 40% with 1 case achieving complete response and 1 a very good partial response. Until now 7 pts entered the phase II part of the trial. Conclusions: In pretreated patients with relapsed MM, MTD was determined to be Bendamustine 40 mg/m2/die on days 1 and 2, and Lenalidomide 10 mg/m2/die on days 1–21, plus Dexametasone 40 mg/die on days 1, 8, 15, and 22. This BdL schedule was relatively tolerated and showed promising efficacy. Based on the mainly myelosuppressive properties, concomitant treatment with growth factors are recommended for all patients. The toxicity profile of BdL scheme resulted in an acceptable treatment-related toxicity and mortality and induced a good quality responses in a pretreated population of MM pts. Disclosures: No relevant conflicts of interest to declare.

Abstract The IV formulation of fludarabine phosphate is an effective treatment in patients with B-cell chronic lymphocytic leukemia (B-CLL), yielding overall response rates of 60% to 80%. An oral formulation of fludarabine phosphate has been developed. In a previously published multicenter, open-label, phase II clinical trial, 81 previously untreated B-CLL patients received 10-mg tablets of fludarabine phosphate (Fludara® oral) 40 mg/m2/day for 5 days, repeated every 4 weeks. The primary endpoint of the trial was response rate, and secondary endpoints included safety and quality of life assessments. Of 81 patients (mean age, 61.2 years; range, 30–75 years) with previously untreated B-CLL, 81.5% were classified as Binet stage B or C. The overall response rate (complete response [CR] + partial response [PR]) using National Cancer Institute (NCI) criteria was 80.2% (12.3% CR and 67.9% PR) and the median time to progression was 841 days (range, 28–1,146 days) (Rossi JF, et al. J Clin Oncol2004;22:1260–1267). The most frequently reported grade 3/4 adverse event was myelosuppression: WHO grade 3/4 hematologic toxicities included granulocytopenia (32.1%), anemia (9.9%), and thrombocytopenia (4.9%). This analysis reports on the long-term follow-up of this cohort during the period from November 2001 to November 2004. Of the 74 patients eligible for the survival analysis, 61 were also assessed for duration of response using NCI criteria: 9 CR (14.8%) and 52 PR (82.2%). During the 3-year follow-up period, 22 (29.7%) patients did not progress. For those who progressed, median time to progression was 29.7 months, and median duration of response was 22.9 months. In 41 (80.4%) of these patients, an increase in circulating lymphocytes was reported as evidence of disease progression. In 23 patients (45.1%), an increase in the sum of the products of at least 2 lymph nodes and/or appearance of new palpable nodes was reported as evidence of disease progression. During the indicated follow-up period, 37 patients (50%) received subsequent treatment. Twelve patients (16.2%) died during the follow-up period: 7 patients (58.3%) due to disease progression, 3 patients (25.0%) due to adverse events, and 2 patients (16.7%) due to other causes. Results from this study suggest that oral fludarabine phosphate is clinically effective and well tolerated by patients with previously untreated B-CLL. Moreover, these data demonstrate that oral fludarabine phosphate achieves response rates and duration of response comparable to those achieved with first-line fludarabine phosphate IV therapy.

Abstract Background: Bortezomib-dexamethasone-thalidomide has been reported to be effective in newly-diagnosed multiple myeloma (MM) with an overall response rate of 92% and a CR rate of 18% (Alexanian et al, Hematology12(3):235–239, 2007), but this regimen has not been reported in Chinese patients. We now report our experience with this combination. Objectives: To investigate the efficacy and safety of bortezomib in combination of dexamethasone plus subsequent thalidomide as primary treatment for MM. Patients and Method: Between June 2006 and August 2007, 11 consecutive newly-diagnosed patients with symptomatic MM were treated with bortezomib at 1.3 mg/m2 IV on days 1, 4, 8 and 11, dexamethasone at 20 mg/m2 IV daily on the day of bortezomib and the day after. All patients received daily oral thalidomide that was escalated from 100 mg to 200 mg. Seven of 11 patients were male and 4 were female. Median age was 57 years (range 47–86). Seven of 11 patients were stage 2 according to the International Staging System, 4 out of 11 patients were stage 3. Eleven patients received a median of 2 cycles of therapy (range 1–6). The Blade criteria were used for response evaluation. Toxicities were evaluated according to the NCI Common Toxicity Criteria version 3. Results: Nine out of 11 patients (82%) achieved PR and 2 (18%) achieved CR; therefore the overall response rate was 100%. With a median follow-up duration of 5 months (1– 14 months), no patients died. Grade 3–4 toxicities included fatigue (3/11), thrombocytopenia (3/11), diarrhea (3/11) and orthostatic hypotension (2/11). Grade 2 neuropathy occurred in 3 out of 11 patients, herpes zoster occurred in 3 out of 11 patients. Routine anticoagulation or anti-thrombosis was not used. There was no DVT/PE in 11 patients. Conclusion: Our preliminary experience indicated that bortezomib-dexamethasone-thalidomide is highly effective in newly-diagnosed MM. Grade 3 and 4 toxicities were rare after median 2 cycles of therapy. The relative lower rates of neuropathy and DVT/PE in this report with Chinese MM patients are being cautiously observed.

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

Abstract Abstract 4081 Background: Carfilzomib, a novel irreversible proteasome inhibitor (PI), has demonstrated single agent activity in, and was recently FDA approved for relapsed and refractory myeloma. Panobinostat, a potent histone deacetylase inhibitor (HDACi), has been studied as a single agent and in combination with bortezomib, demonstrating promising response rates and a favorable safety profile in bortezomib-refractory patients. Our hypothesis proposed that the combination of carfilzomib and panobinostat (Car-Pan) would also be highly active, and we therefore aimed to combine these two agents for the first time. We report the initial findings from the phase I dose-escalation and expansion portions of our phase I/II trial of this novel combination regimen. Methods: The primary objectives were to determine the maximum tolerated dose (MTD) and the safety/tolerability of Car-Pan in patients with relapsed or refractory multiple myeloma. Secondary objectives included determination of the overall response rate, time to progression, progression free survival, and time to next therapy. Panobinostat was administered orally on days 1, 3, 5, 8, 10, 12 of every 28-day cycle, while carfilzomib was given intravenously over 30 minutes on days 1, 2, 8, 9, 15, and 16. Dose level 1 started carfilzomib at 20 mg/m2 with 15 mg of panobinostat, and escalated from there using a standard 3+3 schema based on dose-limiting toxicities (DLTs) occurring in cycle 1. An amendment was later introduced to allow carfilzomib to be given at 20 mg/m2for days 1 and 2 of cycle 1, followed by an increase to the full dose level for that cohort. Adverse events (AEs) were graded using the NCI-CTCAE v4, and responses were assessed with the modified International Uniform Response Criteria. Results: To date, 20 patients have been enrolled, 3 of whom are still in their first cycle, leaving 17 evaluable patients who are described herein, who have received a median of 4 cycles (range 1–8). The median age was 62 years (range 46–73), 11/17 (70%) were male, and the median number of prior regimens was 5 (range 2–15). Patients were very heavily pretreated, with 16/17 (94%) having undergone stem cell transplantation, 16/17 (94%) having prior bortezomib, including 8/17 (47%) who were bortezomib-refractory, and 17/17 (100%) having prior lenalidomide, including 12/17 (70%) who were lenalidomide-refractory. Cytogenetic abnormalities were common, including: 4 with del(17p), 4 with t(4;14), 2 with t(11;14), 9 with del(13), of whom 7 had additional mutations. Grade 1–4 AEs regardless of causality occurring in >20% of patients included anemia (14/17), thrombocytopenia (17/17), neutropenia (8/17), diarrhea (9/17), nausea/emesis (7/17), fatigue (10/17), elevated creatinine (8/17), and pneumonia (5/17). Grade ≥3 AEs regardless of causality included anemia (7/17), thrombocytopenia (10/17), neutropenia (6/17), diarrhea (2/17), nausea/emesis (1/17), fatigue (4/17), elevated creatinine (2/17), and pneumonia (4/17). An MTD has not been established, and dosing is ongoing in cohort 4, with Carfilzomib at 45mg/m2and 20 mg of Panobinostat. Of the 17 evaluable patients, the overall response rate was 35% (6/17) who achieved at least a partial response (PR); including 2 with very good PR (VGPR). In addition, one patient had a minor response, and 65% overall achieved stable disease or better. Conclusions: The combination of Carfilzomib + Panobinostat is well tolerated with a manageable side effect profile. Importantly, the combination achieves a promising response rate in a very heavily pre-treated, lenalidomide/bortezomib/high dose melphalan-refractory population, with an overall response (≥PR) rate of 35%. Updated safety and efficacy data for all patients will be presented at the meeting.

Abstract Background Relapsed or refractory (rel/ref) classical Hodgkin lymphoma (cHL) remains a clinical challenge with limited effective treatments after high dose therapy with autologous stem cell transplantation (ASCT). Lenalidomide (Revlimid®) is an approved anti-neoplastic therapy for multiple myeloma, mantle cell lymphoma and myelodysplastic syndrome with del(5q). It has emerged as an agent with a manageable toxicity profile and promising clinical activity in a number of B cell malignancies. Two clinical trials have evaluated lenalidomide in rel/ref patients with cHL at a dose of 25mg daily for 21 days of a 28 day cycle. One study reported an overall response rate of 14%, a median time to progression of 3.2 month, with a median number of prior therapies of 2. The second study reported an overall response rate of 19%, a cytostatic response rate (CR+PR+SD> 6 month) of 33%, with a median number of prior therapies of 4. The most common reported grade 3-4 side effects in these studies respectively were: neutropenia 28% and 47%, thrombocytopenia 28% and 27%, and anemia 21% and 27%. We report on our experience in this case series with continuous low dose (10-20mg) lenalidomide in rel/ref cHL patients. Methods Twelve rel/ref cHL patients (pts) who previously underwent (or were not candidates for) ASCT and/or clinical trials were administered a daily dose of lenalidomide. Pts received 10mg and were titrated up to 20mg, if tolerated, with continuous dosing for 30 day cycles. Treatment continued until disease progression or the development of unacceptable adverse event at the lowest administered dose (5mg) of lenalidomide. Results The median age at treatment was 33 (range 24-61) years with 5 females. Median number of prior therapies was 8 (range 3-16). Ten pts had received a prior stem cell transplant (9 ASCT, 1 allogenic, and 1 both ASCT and allogeneic). Of the 12 pts, we observed 3 PR (25%), and 9 SD (8 for more than 6 months) for an overall response rate of 25% and an overall cytostatic response rate (CR+PR+SD> 6 month) of 92%. Median number of cycles received was 6 (range 2-15); six patients remain on therapy. One patient with a PR after 2 cycles of therapy underwent allogeneic stem cell transplant. The median time to progression for the remaining 11 patients was 7.5 months (range 4-15 months). Three patients had progression of disease, all of whom were able to enroll on clinical trials. One patient discontinued therapy because of exacerbation of preexisting neuropathy and was able to transition to chemotherapy. A second patient discontinued therapy after experiencing significant fatigue. In general, the treatment was well tolerated, and the most common clinically significant adverse events were: neutropenia in 4 patients which was managed by GCSF support and dose reduction, exacerbation of neuropathy in 2 patients with one patient discontinuing therapy and dose reduction in the second, and diarrhea in one patient managed with dose reduction. Conclusions Despite a far more heavily treated patient population, continuous, low dose, single agent lenalidomide was both tolerable and effective in patients with rel/ref cHL. Continuous low dose lenalidomide is able to provide meaningful time to progression and bridge to further therapy. A clinical trial to evaluate the efficacy of continuous daily dosing of lenalidomide in rel/ref cHL is warranted.

Abstract Introduction Despite therapeutic advances in multiple myeloma, disease relapse is common. Combination therapy with dexamethasone, cyclophosphamide, etoposide, and cisplatin (DCEP) has been utilized as an effective salvage regimen for over a decade, and a recent study reported that DCEP provided an overall response rate of 45.1% when used as salvage therapy in patients who had previously received novel agents (Park S, et al. 2014). Aside from hematologic toxicities, DCEP is generally well-tolerated. In fact, the toxicity profile of DCEP has been compared to high dose cyclophosphamide in the setting of stem cell mobilization and is considered less toxic than the latter. Based upon the synergy noted when proteasome inhibitors are combined with genotoxic therapy, we have combined bortezomib with DCEP in a series of relapsed myeloma patients. Herein we report our experience with the addition of bortezomib to DCEP in relapsed/refractory disease. Patients and Methods We performed a retrospective evaluation of patients with relapsed/refractory multiple myeloma treated at Emory University Hospital from October 2011 until March 2014. Patients received dexamethasone, cyclophosphamide, etoposide, and cisplatin (DCEP) at standard doses in combination with bortezomib at either a dose of 1 mg/m2 or 1.3 mg/m2 administered on Days 1 and 4 of each cycle given every 28 days. Indications for receiving V-DCEP are either cytoreduction prior to SCT (cohort 1) or as salvage therapy (cohort 2). Results Among the 51 patients (49% male and 51% female) included in analysis, the median age at the time of diagnosis is 58 years (range 30-78) and the time of treatment with V-DCEP is 62 years (range 33-79). Among patients that received V-DCEP as cytoreduction prior to SCT, median prior lines of therapy were 1 (0-8). Among the patients that received V-DCEP as salvage therapy, median number of prior lines of therapy was 3 (1-6). ISS 3 disease was seen in 70% of patients and high risk disease in 72.5% of pts (del 17p: 31%; PCL: 19%; extramedullary disease: 33%; complex CTG: 11%) and t(4;14): 6%). Median time from diagnosis to initiation of V-DCEP therapy among cohort 1 is 18 months (0-86) and among cohort 2 is 31 months (12-105) months. Median serum creatinine before C1D1 is 1.17 (0.61-6) and serum bilirubin is 0.6 (0.1-2.8). 31% of patients needed dose reductions from our standard protocol due to organ dysfunction. 47% of patients received ≥2 cycles. The median time to next cycle is 28 days (20-46) and time to next treatment after V-DCEP is 35 days (25-451) suggesting good hematologic recovery. The overall response rate (≥PR) amongst both cohorts with V-DCEP is 47.8% (40% and 51.6% overall response for cohorts 1 and 2, respectively). Figure 1 illustrates response rates. 10 patients that presented with renal insufficiency had renal response including 2 of the 5 patients on hemodialysis. While the median PFS for cohort 1, as expected has not reached, for cohort 2, it is 8 months (95% CI 5.7-10.3). At a median follow-up of 17 months, from the time of V-DCEP initiation, median OS for cohort 2 is 10 months (95% CI 5-14.9). Median overall survival for this predominantly high risk group of patients from diagnosis in cohort 1 is 78 months (95% CI 47-108) and 49 (95% CI 17-80.7) months in cohort 2, respectively. While only 1 patient with grade 2 peripheral neuropathy (PN) received V-DCEP, change from baseline existing PN was seen in 19% of patients (no grade 3/4 events). Conclusions During this era where minimizing alkylator therapy is a consideration, certain indications exist for using V-DCEP such as cytoreduction prior to SCT or as salvage therapy serving as bridge to next line of therapy. Addition of bortezomib to DCEP is deemed safe and is an effective cytoreductive regimen in the treatment of multiple myeloma. Figure 1 Figure 1.

8518 Background: We previously reported the results of a phase I/II trial of PLD, low dose DEX and LEN in patients with relapsed and refractory MM in which the MTD of LEN was 10 mg (for 21 of 28 days) and the overall response rate was 75% with 29% of patients achieving nCR or better (Ann Oncol 2006). Accordingly we evaluated this regimen in ND MM. Methods: We hypothesized that patients with ND MM would tolerate this combination better. Accordingly, patients received PLD (40 mg/m2 on day 1), DEX (40 mg on days 1–4) and LEN (25 mg Days 1–21) every 28 days (for 2 cycles beyond best response: 4–8 cycles). Prophylactic low dose aspirin, acyclovir and fluoroquinolone were recommended. Patients not eligible or not wishing to proceed with high dose therapy continued on the tolerated dose of LEN and DEX until disease progression or unacceptable toxicity. Results: Between 2/2008 and 8/2008, 31 of a planned 60 patients were enrolled. 2 patients were screen failures and are not included in subsequent analysis. The mean age was 64 years (41–82) and 58% were males. The median β2microglobulin was 2.8 mg/dL (34% had β2m>3.5). Using the modified SWOG criteria and after a median of 4 cycles of therapy, the overall response rate was 80% with 40% VGPR and better. Two patients had stable disease and 3 patients had progressive disease. Grade 3/4 hematologic toxicity was as follows: neutropenia (48%), anemia (10%), thrombocytopenia (7%). Grade 3/4 non-hematologic toxicity included: Fatigue (21%), infections and febrile neutropenia (20%, only 1 patient with febrile neutropenia), venous thromboembolic events (10%). 14 patients went off study including 8 patients to proceed with high dose therapy. Conclusions: The combination of PLD, LEN and DEX is an active regimen in patients with ND MM. Due to the unexpected higher rates of neutropenia and fatigue, the dose of PLD will be decreased to 30 mg/m2 every 28 days. Updated results will be presented at the time of the meeting.
