Abstract Patients with relapsed or refractory HL or ALCL have few therapeutic options. Recently, brentuximab vedotin was approved for patients who have relapsed following autologous stem cell transplant (ASCT), and for patients considered ineligible for ASCT. Patients who achieve a complete response experience very durable remissions of their disease. Another agent recently established as active in patients with heavily treated HL is bendamustine, which has been demonstrated to produce a good overall response rate in this setting, though the progression free survival and duration of response are considered modest. The notion that one drug which can produce a rapid response in a majority of patients, coupled with one that can sustain a response led to the concept that a brentuximab vedotin and bendamustine combination could be an excellent salvage regimen for patients with relapsed or refractory disease especially considering their largely non-overlapping toxicity spectra. If this combination produces meaningful complete remissions, it could be used as second line therapy, sparing patient the adverse effects and inpatient stays experienced with ICE based chemotherapy. In this Phase 1 study, we planned to explore 5 dose levels of brentuximab and bendamustine: (1) Bv = 1.2mg/kg; B = 70mg/m2; (2) Bv = 1.2mg/kg; B = 80mg/m2; (3) Bv = 1.8mg/kg; B = 80mg/m2; (4) Bv = 1.8mg/kg; B = 90; and (5) Bv = 1.8mg/kg and B = 100mg/m2. Accrual followed a classic Fibonacchi dose escalation, with 3 patients being treated at each dose level. A Dose Limiting Toxicity, defined as any CTC version 4 Grade 3 or 4 toxicity, excepting modifications for neutropenia, anemia, and thrombocytopenia, nausea and vomiting, diarrhea, alopecia and fatigue, led to expansion of the dose cohort. In brief, the study population consisted of 28 patients accrued to the Phase 1 portion of the study, of which: 18 were male; 27 had HL and 1 ALCL; the median number of prior systemic therapies was 5 (range 1-14); with 17 patients having had prior ASCT and 11 prior radiation therapy. The maximum tolerated dose (MTD) was Bv = 1.8 mg/m2 and 90 mg/m2 of bendamustine. The DLT was not reached, as the study called for only 5 dose cohorts, with the highest dose cohort being defined by the MTD of the individual drugs. To date, 27 patients were evaluable for response. Two patients (7%) experienced a complete remission, and 10 had a partial remission, for an overall response rate of 44%. Ten patients had stable disease. Interestingly, among the 9 patients who had prior Bv, 4 responded (44%) (PR=4, SD=2, POD=3), and of the 4 patients who had prior B, 2 responded (50%) (PR=2, SD=1, POD=1). The study is now being expanded into a Phase 2 study, where an additional 37 patients will be accrued. In addition, plasma and serum was collected from every patient, which are being analyzed for a variety of immunological biomarkers which will be correlated with toxicity and response. We believe that in this very heavily treated patient population, the combination of Bv and B represents a highly promising combination for patients with relapsed or refractory HL and ALCL.

Abstract For patients with indolent non-Hodgkin lymphoma who fail initial anti-CD20–based immunochemotherapy or develop relapsed or refractory disease, there remains a significant unmet clinical need for new therapeutic approaches to improve outcomes and quality of life. 177Lu-lilotomab satetraxetan is a next-generation single-dose CD37-directed radioimmunotherapy (RIT) which was investigated in a phase 1/2a study in 74 patients with relapsed/refractory indolent non-Hodgkin B-cell lymphoma, including 57 patients with follicular lymphoma (FL). To improve targeting of 177Lu-lilotomab satetraxetan to tumor tissue and decrease hematologic toxicity, its administration was preceded by the anti-CD20 monoclonal antibody rituximab and the “cold” anti-CD37 antibody lilotomab. The most common adverse events (AEs) were reversible grade 3/4 neutropenia (31.6%) and thrombocytopenia (26.3%) with neutrophil and platelet count nadirs 5 to 7 weeks after RIT. The most frequent nonhematologic AE was grade 1/2 nausea (15.8%). With a single administration, the overall response rate was 61% (65% in patients with FL), including 30% complete responses. For FL with ≥2 prior therapies (n = 37), the overall response rate was 70%, including 32% complete responses. For patients with rituximab-refractory FL ≥2 prior therapies (n = 21), the overall response rate was 67%, and the complete response rate was 24%. The overall median duration of response was 13.6 months (32.0 months for patients with a complete response). 177Lu-lilotomab satetraxetan may provide a valuable alternative treatment approach in relapsed/refractory non-Hodgkin lymphoma, particularly in patients with comorbidities unsuitable for more intensive approaches. This trial was registered at www.clinicaltrials.gov as #NCT01796171.

Abstract Introduction: Despite the recent introduction of novel agents for multiple myeloma (MM), the disease remains incurable and invariably progresses through these new therapies. Patients with quad-refractory MM (refractory to bortezomib, carfilzomib, lenalidomide, and pomalidomide) and penta-refractory MM (refractory to an anti-CD38 monoclonal antibody as well) are left with few treatment options and poor prognoses. The chemotherapy regimen of dexamethasone, cyclophosphamide, etoposide, and cisplatin (DCEP) has demonstrated efficacy in the treatment of relapsed/refractory MM. We and others employ DCEP as a salvage regimen, however, few outcomes data exist in this heavily pretreated population. Methods: We conducted a retrospective study to identify all patients who received DCEP for quad- or penta-refractory MM at our institution between 2013 and 2018. Disease response and refractoriness were defined by IMWG criteria. The primary endpoint was overall response rate (ORR) defined as PR or better. Secondary endpoints included overall survival (OS), progression-free survival (PFS), and duration of response (DOR). Results: We identified 31 patients who received DCEP, 8 (26%) for quad-refractory and 23 (74%) for penta-refractory MM (Table 1). Twenty-eight (90%) had at least one autologous stem cell transplant, and one had a prior allogeneic transplant. Sixteen (52%) were female, 27 (87%) were white, and median age at DCEP was 60. Median number of prior treatment regimens was 8. All patients received dexamethasone (40mg/day), cyclophosphamide (400mg/m2/day), etoposide (40mg/m2/day), and cisplatin (10mg/m2/day) on days 1-4 (Lazzarino et al. 2001). Cycles were generally 28 days in length, but doses were delayed in cases of cytopenias or other toxicities. Dose reductions occurred in cases of renal impairment or prolonged cytopenias. Twenty patients (65%) received more than one cycle (range: 1-5). The overall response rate was 35%. One patient achieved CR allowing him to proceed to a second autologous transplant. One patient achieved a VGPR, 9 (29%) a PR. Four of the 8 (50%) quad-refractory patients responded compared to 7 of the 23 (30%) of the penta-refractory patients. Eleven (35%) were primary refractory to DCEP, and two patients died after one cycle prior to response assessment. The overall median PFS was 2.7 months (95% CI 1.5-3.8) and median OS was 6.2 months (95% CI 4.4-7.8). For responders, median DOR was 4.2 months (95% CI 3.0-5.4) and median OS was 9.0 months (95% CI 7.2-10.9). Conclusion: Quad- and penta-refractory MM carry a grim prognosis. In our retrospective study, DCEP led to a notable ORR of 35% (95% CI 19%-55%) in this very heavily-treated population, and suggests that it remains a reasonable salvage therapy. Furthermore, it supports prospective study of this regimen, possibly in combination or in comparison with other agents effective in quad- or penta-refractory MM.

Abstract Introduction: Despite significant advances in multiple myeloma (MM) therapy, disease progression through multiple novel treatments is often inevitable. Quad-refractory MM (refractory to bortezomib, carfilzomib, lenalidomide, and pomalidomide), or penta-refractory MM (refractory to an anti-CD38 monoclonal antibody as well) portends a poor prognosis, with few subsequent lines of treatment currently available. We and others have used bendamustine combined with corticosteroids as a salvage regimen, but there is a paucity of outcomes data in this heavily pretreated population. Methods: We conducted a retrospective study to identify all patients who received bendamustine with corticosteroids for quad- or penta-refractory MM at our institution between 2013 and 2018. Disease response and refractoriness were defined by IMWG criteria. The primary endpoint was overall response rate (ORR) defined as PR or better. Secondary endpoints included overall survival (OS) and duration of response (DOR). Results: Twenty-seven patients were identified; 5 patients were quad-refractory, and 22 penta-refractory (Table 1). Twenty-two (81%) patients had at least one prior autologous stem cell transplant and 1 had a prior allogeneic. The median age at time of bendamustine was 61, 52% were female, and 85% were white. All patients received bendamustine at a dose of 90mg/m2 on days 1 and 2 of a 28 day cycle. Twelve patients (44%) received more than one cycle (range: 1-8). The overall response rate was 26%. While no patient achieved CR, 4 achieved VGPR and 3 a PR. Two of the 5 (40%) quad-refractory patients responded compared to 5 of the 22 (23%) penta-refractory. Sixteen (59%) were primary refractory to bendamustine and one patient went onto hospice prior to response evaluation. Overall the median PFS was 1.4 months (95% CI 1.1-1.6) and median OS was 8.7 months (95% CI 2.3-15.0). For responders (≥PR), median DOR was 6.6 months (95% CI 0.0-13.7) and median OS was 14.0 months (95% CI 0.6-27.4). Conclusion: The prognosis of quad- and penta-refractory MM remains poor. In this heavily pre-treated population, bendamustine demonstrates a 26% ORR (95% CI 11%-46%). The DOR and OS of the patients was poor but highly heterogeneous. Those who did respond to bendamustine had notably improved OS. Given the limited available options for quad- and penta-refractory MM, bendamustine remains a reasonable salvage therapy. Prospective trials are warranted perhaps including additional agents that are effective in penta-refractory patients.

Purpose Brentuximab vedotin, a monoclonal antibody (cAC10) conjugated to monomethyl auristatin E, targets CD30+ receptors. This phase II open-label trial was conducted to evaluate safety and efficacy in CD30+ cutaneous T-cell lymphomas. Patients and Methods Forty-eight patients with CD30+ lymphoproliferative disorders or mycosis fungoides (MF) received an infusion of 1.8 mg/kg every 21 days. Results Forty-eight evaluable patients (22 women and 26 men; median age, 59.5 years) had an overall response rate of 73% (95% CI, 60% to 86%; 35 of 48 patients) and complete response rate of 35% (95% CI, 22% to 49%; 17 of 48 patients). Fifteen (54%; 95% CI, 31% to 59%) of 28 patients with MF responded, independent of CD30 expression. In patients with MF/Sézary syndrome, the overall response rate was 50% (five of 10 patients) in patients with low CD30 expression (< 10%), 58% (seven of 12 patients) in patients with medium expression (10% to 50%), and 50% (three of six patients) in patients with high expression (≥ 50%). Time to response was 12 weeks (range, 3 to 39 weeks), and duration of response was 32 weeks (range, 3 to 93 weeks). All patients with lymphomatoid papulosis (n = 9) and primary cutaneous anaplastic T-cell lymphomas (n = 2) responded; time to response was 3 weeks (range, 3 to 9 weeks), and median duration of response was 26 weeks (range, 6 to 44 weeks). Soluble baseline CD30 levels were lowest in complete responders (P = .036). Grade 1 to 2 peripheral neuropathy was observed in 65% of patients (95% CI, 52% to 79%; 31 of 48 patients), is still ongoing in 55% of patients (95% CI, 41% to 69%; 17 of 31 patients), and resolved in 45% of patients (95% CI, 31% to 59%; 14 of 31 patients), with a median time to resolution of 41.5 weeks. Grade 3 to 4 events were neutropenia (n = 5), nausea (n = 2), chest pain (n = 2), deep vein thrombosis (n = 1), transaminitis (n = 1), and dehydration (n = 1). Dose reductions to 1.2 mg/kg were instituted as a result of grade 2 neuropathy (n = 6), transaminitis (n = 1), and arthralgias and fatigue (n = 2). Conclusion Brentuximab vedotin is both active and well tolerated in cutaneous T-cell lymphoma and lymphomatoid papulosis, with an overall response rate of 73% and complete response rate of 35%.

Abstract Lumiliximab is a PRIMATIZED® anti-CD23 monoclonal antibody with human IgG1 constant regions and macaque variable regions. Preclinical data demonstrated that lumiliximab enhanced both fludarabine- and rituximab- mediated apoptosis in CLL cells. Thus, a Phase 1/2, open-label, dose-escalation, multicenter study (Study 152–30) evaluating lumiliximab + fludarabine, cyclophosphamide, and rituximab (L + FCR) for relapsed CD23+ B-cell CLL was initiated. Treatment has been completed and follow-up is ongoing. Thirty-one patients (pts) received either 375 mg/m2 (n=3) or 500 mg/m2 (n=28) of lumiliximab in combination with a 28-day cycle of FCR for up to 6 cycles. Median age at study entry was 58 yrs. The majority of pts (74%) were Rai Stage I/II. The most common adverse events included nausea (77%), pyrexia (61%), chills (55%), neutropenia (55%), and fatigue (48%). Twenty pts (65%) experienced a Grade 3 or 4 event. An overall response rate of 71% was demonstrated: 48% complete response (CR), 10% partial response (PR), and 13% unconfirmed PR. Currently, baseline cytogenetic data is available for 21 pts who received 500 mg/m2 of lumiliximab. Although preliminary, 1 of the 4 pts with del(17p13.1) responded; of the 6 pts with del(11q22.3), 5 responded with 4 attaining a CR. A comparison with published data from a study of FCR alone in 177 pts with relapsed or refractory CLL conducted at the M.D. Anderson Cancer Center (MDACC) (Wierda W, O’Brien S, Wen S, et al. J Clin Oncol.2005;23:4070–4078) demonstrated that L + FCR has an acceptable safety profile, does not appear to increase the toxicity (including myelosuppression) of the FCR regimen, and compares favorably with the CR rate of the FCR regimen alone, as displayed in Table 1. Most pt characteristics (age, gender, median number of prior therapies, and WHO performance status) were similar between the 2 studies; however, more pts in the MDACC study were Rai Stage III-IV (50% vs 22%) and were rituximab-naïve (88% vs 40%). Furthermore, there were no obvious differences in hematologic toxicity between the 2 studies and the tolerability of L + FCR was similar to that of FCR, with approximately 50% percent of pts completing 6 cycles of treatment in both studies. These data suggest that L + FCR may produce a higher complete response rate than FCR without additional toxicity. Based upon this data, a multicenter, global, randomized study of L + FCR vs. FCR alone is being initiated. Table 1. Comparison of Responses in Study 152–30 and the MDACC Study Study 152–30, L + FCR (N=31), n (%) MDACC, FCR (N =177), n (%) 1CR and PR response criteria were the same in both studies. 2PRu is included in the OR.

Abstract Background: The mammalian target of rapamycin (mTOR) inhibitor Everolimus (RAD001, Certican®) is a new immunosuppressive drug and beside of sirolimus used and approved in solid organ transplantation. Recently, it was reported that mTOR-inhibitors in combination with calcineurin inhibitors (CNI) showed clinical responses in chronic graft-versus-host disease (cGvHD). In this single centre retrospective analysis, we report on 29 patients (pts) with severe cGvHD treated with Everolimus without CNI. Patients and Methods: Twenty-nine pts (17 AML, 3 CML, 4 ALL, 3 CLL, 2 NHL) with a median age of 44 years [range: 25–61] underwent allogeneic stem cell transplantation between September 1999 and August 2007. Myeloablative conditioning was used in 21 pts, reduced-intensity conditioning in 8 pts. Except for one patient receiving bone marrow, all pts received peripheral blood stem cells for transplantation. Family donors (2 non-fully HLA matched) were used in 7 pts (24%) and unrelated donors (7 non-fully HLA-matched) in 22 pts (76%). GvHD-prophylaxis consisted of CNI (cyclosporine or tacrolimus) in 4 pts, CNI+Methotrexate (MTX) in 8 pts, CNI+Mycophenolate (MPA) in 8 pts and CNI+MPA+MTX in 9 pts. Antithymocyte globulin (ATG) as in vivo T-cell depletion was used in 9 pts. Cytomegalovirus (CMV)-serostatus was positive in 14 pts, with seronegative donors in 5 pts. Acute GvHD occurred in 27/29 (93.3%), grade II-IV in 25 (86.2%). At the same time, CMV reactivation/infection was observed in 11 pts and thrombotic microangiopathy (TMA) in 3 pts. All pts developed severe cGVHD with extensive disease. Organ involvement included skin with scleroderma in 21 pts, mucous membranes in 22 pts, eyes in 22 pts, lungs in 8 pts, liver in 11 pts, gut in 9 pts and arthralgia in 6 pts. At the time of treatment start with everolimus (0.75 mg Certican ® twice a day orally), CNI medication was stopped. The intended plasma therapeutic levels of everolimus were 3–8 mg/l. In addition all pts received prednisone and in 18 pts (62%) MPA as third immunosuppressive agent was continued. Results: Median treatment duration was 8.4 months [range: 2.5–21.7]. None of the pts developed CMV disease or TMA. Adverse events were: arterial hypertension in 1 patient, atrial fibrillation in 1 patient, pneumonia in 1 patient, sinusitis in 1 patient, herpes labials infection in 1 patient, renal insufficiency grade II in 2 pts and myalgia in 2 pts. 96.6% are still alive, 1 patient (3.4%) died due to relapse of ALL. Two pts (6.9%) achieved a complete response of their cGvHD and 18 pts (62.1%) a partial response resulting in an overall response rate of 69.0% (n=20) according to the recent consensus NIH report (Biol. Blood Marrow Transplant. 2006 May; 12(5): 491–505). No change was observed in 3 pts (10.3%) and progression occurred in 6 pts (20.7%). Complete response in HLA-identical related donors was 20% (1/5) and with HLA-matched unrelated donors was 6.7% (1/15). 100% (n=2) of pts with a HLA-mismatched related donor achieved a partial remission and 85.7% (n=6) of pts with a HLA-mismatched unrelated donor. The gender of recipient or donor did not impair the observed responses with everolimus. Prednisone could be tapered in 62.1% of all pts (18/29). In the triple combination with MPA, MPA could be tapered in 22.2% (4/18) and could be stopped in 38.9% (7/18). Conclusions: A CNI-free treatment of advanced extensive cGvHD with everolimus seems to be feasible and effective with a high overall response rate of nearly 70 %. It should be emphasized that a low toxicity profile without TMA was observed. Our data supports further clinical and immunological investigations with m-TOR inhibitor everolimus in treating GvHD.

Abstract Abstract 3061 The current bortezomib schedule involves administration of the drug twice a week at 1.3 mg/m2 for 2 weeks every 21 days. This regimen although effective is inconvenient and associated with side effects including neuropathy and gastrointestinal toxicities that limits its use in a proportion of patients. Therefore, to improve convenience and compliance, we have investigated efficacy and safety of a weekly regimen of bortezomib. In this one-stage phase II multi-center, open-label single-arm study bortezomib is administered once a week at 1.6 mg/m2 in combination with dexamethasone in newly-diagnosed multiple myeloma patients not considered for autologous stem cell transplant in participating Veterans Hospitals nationwide. The objective is to evaluate overall response rate and toxicity of this regimen. Patients received bortezomib at 1.6 mg/m2 IV weekly for 4 weeks followed by 1 week off and dexamethasone 40mg PO on the day of and day after each dose of bortezomib. Patients may receive 6 such 5-week cycles. At the current time 32 patients (median age - 73; range 50–88) have been enrolled at 11 Veterans Administration Hospital across the U.S. Patients had significant co-morbidities including 61% with cardiovascular problems, 58% with diabetes and/or hyperlipidemia, 58% with elevation of serum creatinine, 26% with respiratory problems and 23% with previous history of cancer. All patients were at least on 5 daily medications. Of the 32 patients enrolled, 25 patients have received at least one cycle of therapy and were evaluable for toxicity and efficacy, while 6 patients have received less than one cycle of therapy and one patient has inadequate data. With a median of 4 cycles administered, this regimen was well tolerated. None of the patients have developed grade 3 neuropathy, while grade 1 neuropathy was observed only in 2 patients and one patient with grade 1 neuropathy at diagnosis had increase to grade 2. Dexamethasone dose was reduced in 29% patients while 6% required reduction in bortezomib dose to 1.3 mg/m2. Additionally, Grade ≥1 asthenia was observed in 42%, diarrhea in 35%, and thrombocytopenia in 26%. Four patients have died of co-morbidities which were considered unrelated or probably unrelated to the treatment with bortezomib. The partial response or better was achieved in 68% patients receiving at least 1 cycle of therapy; 20% patients achieved CR/nCR and additional 12% achieved VGPR. Including MR in the analysis, overall response was observed in all evaluable patients. On intent to treat analysis including all 32 patients, overall response rate (≥ MR) was observed in 78% patients and PR or better in 53% patients. These preliminary results suggest that the once a week bortezomib regimen is effective and tolerable with reduced toxicity even in this older patient population with significant co-morbidities.

Abstract This study's objective was to evaluate the efficacy and safety of gemcitabine in combination with oxaliplatin (GEMOX) as a salvage regimen in patients with relapsed or refractory Hodgkin's lymphoma. Twenty-five patients were enrolled. All patients had received ≥ 2 prior chemotherapy regimens, had an ECOG performance status ≤ 2 and had adequate organ function. Patients received intravenous gemcitabine (1000 mg/m2) and oxaliplatin (100 mg/m2) on days 1 and 15, every 4 weeks. The median age was 29 years (range, 18-64) and 16 (68%) were male. Twenty-one (84%) had primary refractory disease (n=13) or relapsed within 12 months after initial therapy (n=8). All had previous platinum-based salvage chemotherapy (ICE, 23; DHAP, 2). Ten patients (40%) had relapsed/refractory disease following autologous stem cell transplantation (SCT). None had previous brentuximab vedotin treatment. Twenty-one (84%) patients were refractory or progressive on the last treatment. Median number of previous lines of chemotherapy was 2 (range, 2-4). Median number of GEMOX cycles administered to the patients was 3 (range, 2-6). Treatment response was evaluated with PET-CT before and 2-3 cycles after treatment, and those patients who demonstrated a response continued to receive a maximum of 6 courses of GEMOX or bridged to SCT. Of 25 patients, 2 (8%) had complete response, 9 (36%) had partial response and the remaining patients had refractory/progressive disease with an overall response rate of 44%. Seven of the 10 patients who had relapsed/refractory disease after autologous SCT achieved a response (CR, 2; PR, 5). The median time to progression for responding patients was 3 months (range, 1-40 months). One patient is disease free for 40 months. Three patients were successfully bridged to SCT (autologous, 2; allogeneic, 1). Main toxicity was hematological. Grade ≥ 3 hematologic toxicity occurred in 10 patients: thrombocytopenia (36%), neutropenia (16%) and anemia (8%). Among these, 7 had previous autologous SCT. One patient had grade 4 neutropenia and thrombocytopenia. Treatment cycle postponed in 6 patients without dose reduction because of hematological toxicity. Seven patients (28%) needed G-CSF support. One patient developed febrile neutropenia. No treatment-related deaths occurred. GEMOX was shown to be an effective salvage regimen in patients with relapsed/refractory Hodgkin's lymphoma, producing an overall response rate of 44%. It is an active regimen in patients who had relapsed/refractory disease after autologous SCT. Although, the median PFS time was short, some patients can be bridged to SCT and some can get long-term PFS. Hematological toxicity was common, especially in patients with previous autologous SCT.

8027 Background: The histone deacetylase inhibitors (HDIs) are a class of differentiating agents undergoing clinical testing. Like other HDIs, romidepsin (FK228) modulates expression of genes involved in cell cycle regulation and markers of differentiation in cancer cell lines, leading to induction of differentiation or apoptosis. Romidepsin has demonstrated clinical activity in patients with T-cell lymphoma. Methods: Patients with CTCL (42) or PTCL (36) were enrolled in the NCI multi-institutional trial and assigned to cohorts based on extent of prior therapy and pathology. Romidepsin is administered on days 1, 8, and 15 of a 28 d cycle with a starting dose of 14mg/m2. Responses for patients with PTCL are measured using Cheson criteria, and CTCL using RECIST criteria. Results: Cohort one, composed of 27 patients who had previously received no more than 2 prior cytotoxic regimens of chemotherapy, has completed enrollment. Responses observed include 3 patients with CR and 7 patients with partial responses, yielding an overall response rate of 37%. Of note, responses were observed independent of stage of disease. Among 18 patients with stage IV disease, 6 patients had a complete or partial response, including 3 patients with Sézary syndrome. When including patients with greater than 2 prior cytotoxic regimens, the overall response rate was 31%. A replicate arm has been opened with the goal of confirming the response rate observed in the first cohort. Response data have not been evaluated from this arm at this time. Responses observed in 36 patients with refractory or relapsed PTCL includes 3 patients with CR and 8 patients with partial responses, comprising an overall response rate of 30%. Responses were observed independent of prior therapy, with some patients having undergone prior stem-cell transplant. Molecular endpoint analysis was performed on peripheral mononuclear cells (PBMNCs) and tumor biopsies from treated patients evaluating histone acetylation and changes in gene expression. Conclusions: Romidepsin as a single agent appears to have significant single agent activity in patients with CTCL and PTCL. Combination therapy with romidepsin may increase efficacy and should be pursued. This protocol remains open to accrual. No significant financial relationships to disclose.

Aggresome Formation

8530 Background: Aggresome formation is a mechanism of resistance to agents (e.g., bortezomib) which block proteasome activity. HDACi (e.g., quisinostat) prevents aggresome formation by deacetylation of tubulin that allows the transport of unfolded proteins to lysosomes for degradation. Methods: Patients received quisinostat (Q) at escalated doses (6, 8, 10 and 12 mg) on days 1, 3, and 5 weekly, subcutaneous VELCADE (V) at 1.3 mg/m2on days 1, 4, 8, and 11 of a 3-week cycle, and oral dexamethasone (D) at 20 mg on the day of and the day after VELCADE dosing. The primary endpoint was the maximum tolerated dose (MTD) of Q in the combination (Q+V+D). The secondary endpoints included safety, overall response rate, and pharmacodynamic biomarkers. Results: Eighteen patients (3, 3, 6, and 6 in increasing Q doses) were enrolled: 56% male; median age = 69 (range 50-82) years; multiple myeloma stage: IA = 11% and IIIA = 89%; prior lines of therapy: 1 = 100%, 2 = 55.6%, and 3 = 11.1%; prior VELCADE treatment = 50%. At the highest dose (12 mg) 2 patients had dose-limiting toxicity, 1 with QTc prolongation and 1 with atrial fibrillation. The MTD was established at the 10 mg Q for the Q+V+D regimen. The most common adverse events (≥ 10% of patients) were diarrhea (39%), asthenia (33%), peripheral oedema (22%), nausea (17%), thrombocytopenia (17%), alopecia (11%), constipation (11%), and vomiting (11%); most were grade 2 or lower in toxicity. To date, 13 patients have discontinued treatment, of which 5 completed 11 cycles of treatment. The overall response rate was 87.5% (14/16, 95% CI: 61.7% to 98.5%), including 1 complete response, 2 very good partial response, and 11 partial responses. Most patients (9/11) showed a decrease in number of circulating multiple myeloma cells after 1 cycle. Two of 5 patients showed an increase in acetylated histone 3 from baseline as measured in peripheral blood mononuclear cells. Conclusions: The MTD is 10 mg quisinostat in combination with VELCADE and dexamethasone. The combination is active in the treatment of relapsed multiple myeloma and has an acceptable safety profile. Clinical trial information: NCT01464112.
