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.

PURPOSE The aim of this open-label, first-in-setting, randomized phase III trial was to evaluate the efficacy of alisertib, an investigational Aurora A kinase inhibitor, in patients with relapsed/refractory peripheral T-cell lymphoma (PTCL). PATIENTS AND METHODS Adult patients with relapsed/refractory PTCL—one or more prior therapy—were randomly assigned 1:1 to receive oral alisertib 50 mg two times per day (days 1 to 7; 21-day cycle) or investigator-selected single-agent comparator, including intravenous pralatrexate 30 mg/m2 (once per week for 6 weeks; 7-week cycle), or intravenous gemcitabine 1,000 mg/m2 or intravenous romidepsin 14 mg/m2 (days 1, 8, and 15; 28-day cycle). Tumor tissue (disease subtype) and imaging were assessed by independent central review. Primary outcomes were overall response rate and progression-free survival (PFS). Two interim analyses and one final analysis were planned. RESULTS Between May 2012 and October 2014, 271 patients were randomly assigned (alisertib, n = 138; comparator, n = 133). Enrollment was stopped early on the recommendation of the independent data monitoring committee as a result of the low probability of alisertib achieving PFS superiority with full enrollment. Centrally assessed overall response rate was 33% for alisertib and 45% for the comparator arm (odds ratio, 0.60; 95% CI, 0.33 to 1.08). Median PFS was 115 days for alisertib and 104 days for the comparator arm (hazard ratio, 0.87; 95% CI, 0.637 to 1.178). The most common adverse events were anemia (53% of alisertib-treated patients v 34% of comparator-treated patients) and neutropenia (47% v 31%, respectively). A lower percentage of patients who received alisertib (9%) compared with the comparator (14%) experienced events that led to study drug discontinuation. Of 26 on-study deaths, five were considered treatment related (alisertib, n = 3 of 11; comparator, n = 2 of 15). Two-year overall survival was 35% for each arm. CONCLUSION In patients with relapsed/refractory PTCL, alisertib was not statistically significantly superior to the comparator arm.

Background: Angioimmunoblastic T-cell lymphoma (AITL) is a relatively common subtype of peripheral T-cell lymphoma (PTCL) that typically presents with lymphadenopathy, extranodal disease, including rash, and is associated with frequent infections due to immune dysregulation. Patients with AITL generally have a poor prognosis, even with aggressive chemotherapy as responses to standard chemotherapy are often suboptimal. Recent advances in cancer biology suggest that AITL is derived from T-follicular helper cells and is often characterized by gross epigenetic dysregulation. Histone deacetylase (HDAC) inhibitors have demonstrated significant activity in T-cell neoplasms. The BELIEF trial established an overall response rate of 25% in patients with relapsed/refractory PTCL who were treated with belinostat, with a duration of response of about 1 year, leading to accelerated approval. Herein, we present a subset analysis of the data for patients with AITL. Methods: Patients with histologically confirmed PTCL (N = 129) who experienced failure with or refractory to ≥ 1 prior systemic therapy received belinostat 1,000 mg/m(2) as daily 30-minute infusions on days 1 to 5 every 21 days. Central assessment of response used International Working Group criteria. Primary endpoint was overall response rate (ORR). Secondary endpoints included duration of response (DoR) and progression-free and overall survival (PFS). Results: Of 129 patients, 22 patients had AITL; most had advanced disease (91% stage III/IV; 36% with bone marrow involvement). The median number of prior therapies was 2 (range, 1-5), and 3 (14%) patients were refractory to their last line of therapy. The ORR for patients with AITL was 46% (10/22; 95%CI: 24 - 68%), with a complete response (CR) in 4 of 22 patients (18%). Of the ten responders, the median time to response of 11.3 weeks (range, 4.7 - 24.4 weeks) in the AITL subgroup. After a median follow up of 21.5 months, the median PFS was 4.2 months (95%CI: 1.5 -13.9) and the median DOR was 13.6 months (95%CI: 1.4 - 29.4) as shown in Figure 1. For all patients with AITL treated with belinostat, the median OS was 9.2 months (95%CI: 6.8 - 21.5). The most common grade 3 to 4 adverse events were asthenia (n=2), fatigue (n=2), anemia (n=2), thrombocytopenia (n=2), neutropenia (n=2), and septic shock (n=2). Conclusions: Single-agent belinostat induced rapid and durable responses in patients with relapsed/refractory AITL. At the end of the study, there were 37% patients with ongoing responses at 2 years. Patients with clinical benefit from belinostat continued treatment until progression of disease. These results support the use of belinostat in relapsed/refractory AITL as a single agent and provide rationale for combination therapies in clinical trials.

Abstract Abstract 3135 Peripheral T cell lymphoma, not otherwise specified (PTCL, NOS) is heterogenous groups of aggressive T-cell lymphoma and treatment outcome is dismal. Lymphopenia is an independent prognostic factor for survival for B-cell lymphoma. The ALC at diagnosis on survival in T-cell lymphoma has not been studied. Thus, we studied the role of ALC at diagnosis on clinical outcome in patients with PTCL, NOS. Between 2001 and 2009, 32 patients with PTCL, NOS reviewed for the study. Median patient age was 57 (range 34–78) years. Median ALC at the time of diagnosis was 1.54 (range 0.41–12.64×109/L). Patients were divided two groups according to ALC count 1.0 ×109/L. Ten patients (31%) had lower ALC at diagnosis. Median follow up duration was 299 days (range 11–2164 days). Overall response rate was 61.5% (16 of 26 patients) and complete response (CR) rate was 42% (11 of 26 patients). Only two patients reached CR in low ALC group.There was no significant difference in overall response rate because of small number of patients. Superior overall survival was observed with an ALC 1.0 × 109/L (N = 22) versus an ALC < 1.0 × 109/L (N=10) (median OS: not reached vs 242 days, OS rates at 5 years, 57% vs 0%, p =0.016, respectively). Multivariate analysis demonstrated ALC to be an independent prognostic indicator for OS (Hazard Ratio 3.5, 95% confidence intervals 1.2–10.2; p<0.019) when compared to the International prognostic index (IPI) and Prognostic Index for PTCLU (PIT). This study suggested that low ALC is an independent prognostic factor for survival in patients with PTCL, NOS. Disclosures: No relevant conflicts of interest to declare.

Purpose Peripheral T-cell lymphoma (PTCL) is a poor prognosis subtype of non-Hodgkin's lymphoma with no accepted standard of care. This study evaluated the efficacy and tolerability of pralatrexate, a novel antifolate with promising activity. Patients and Methods Patients with independently confirmed PTCL who progressed following ≥ 1 line of prior therapy received pralatrexate intravenously at 30 mg/m2/wk for 6 weeks in 7-week cycles. Primary assessment of response was made by independent central review using the International Workshop Criteria. The primary end point was overall response rate. Secondary end points included duration of response, progression-free survival (PFS), and overall survival (OS). Results Of 115 patients enrolled, 111 were treated with pralatrexate. The median number of prior systemic therapies was three (range, 1 to 12). The response rate in 109 evaluable patients was 29% (32 of 109), including 12 complete responses (11%) and 20 partial responses (18%), with a median DoR of 10.1 months. Median PFS and OS were 3.5 and 14.5 months, respectively. The most common grade 3/4 adverse events were thrombocytopenia (32%), mucositis (22%), neutropenia (22%), and anemia (18%). Conclusion To our knowledge, PROPEL (Pralatrexate in Patients with Relapsed or Refractory Peripheral T-Cell Lymphoma) is the largest prospective study conducted in patients with relapsed or refractory PTCL. Pralatrexate induced durable responses in relapsed or refractory PTCL irrespective of age, histologic subtypes, amount of prior therapy, prior methotrexate, and prior autologous stem-cell transplant. These data formed the basis for the US Food and Drug Administration approval of pralatrexate, the first drug approved for this disease.

Abstract Abstract 4771 Approximately 12- 15% of non- Hodgkin lynphoma NHL are caused by malignant Tcell lymphocytes. The success of the treatment in the aggressive form has lagged behind that of B -Cell in term of poor resonse and durability. Peripheral T-Cell lymphoma PTCL and cutaneous T-Cell lymphoma CTCL are two major charachterized classifiction in the World Health Organization based on their morphology, growth patern and genetics. Stem cell transplant and high dose chemotherapy have been associated with long term response rate of 45%. However this treatment is not well tolerated and not feasible for many patients. Other theraputic options include cytotoxic drugs CHOP,CVP regimen, purine analogues, Denileukin diftitox, Histone deacetylation inhibitors and novel antifolates drugs. In this abstract we will show our experience with gemcitabin an active antimetabolite as a single agent or in combination with other active drugs. Eight patients with PTCL, five with visceral stage of mycosis fundoides( one patient with HIV infection), two with refractory anaplastic Ki positive NHL and one with angioimmunoblastic type. All patients failed a minimum two lines of therapy. Mean age 58 years( range 28-75). Eight blacks, two whites, four hispanics and one asian. Meduim cycles given are four. The dose range 800-1000 mg/M2, given weekly x3 every 28 days cycle. Overall response rate is 85%. Complete response rate CR in eight patients ( three PTCL, three mycosis fungoides and two anaplastic large cell NHL). Partial response PR in four and stable disease in one. Median duration of response is nine months, range six to two years. Median time for response is six weeks. In conclusion:Gemcitabine is an active drug in T-Cell lymphomas particularly when used in combination with other active agents. Maintenance dosing or retreatment with this drug should be investigated. Disclosures: No relevant conflicts of interest to declare.

Background Extranodal NK/T cell lymphoma (ENKTL) is rare in western countries but rather common in Asia and South America, characterized with Epstein-Barr virus (EBV) infection. Patients with advanced stage (III/IV) ENKTL has a poor survival and low response to conventional CHOP-like chemotherapy, with a 5-year overall survival rate of only 30%. Retrospective study showed that SMILE regimen had a certain effect on ENKTL, but the toxicity limited its further clinical application. More effective treatment regimens are required to be explored for systematic, prospective, controlled, randomized clinical trials. Recently, studies revealed that asparaginase-based combination chemotherapy such as P-Gmox(Pegaspargase, Gemcitabine, Oxaliplatin)is effective in patients of ENKTL. However standard treatment for newly untreated advanced ENKTL is still controversial. We developed a refined chemotherapeutic DDGP (dexamethasone, cisplatin, gemcitabline, and peg-asparaginase) regimen and proceeded a prospective randomized, multicenter and open-label clinical trial to evaluate and compare the efficacy and safety of DDGP with SMILE regimen in patients with newly diagnosed stage III/IV ENKTL in January 2011. Based on the encouraging interim results in 2016(Li, L et al.Clin Cancer Res, 2016), we presented the final results of this clinical investigation (ClinicalTrials.gov, No. NCT01501149). Patients and methods: The study was initiated at 9 centers in China in January 2011. Patients aged 14-70 with newly diagnosed ENKTL in stages III/IV, and ECOG performance score of 0-2 were enrolled. According to a computer-generated randomization schedule, eligible patients were assigned either DDGP regimen (cisplatin 20 mg/m² on day 1-4; dexamethasone 15mg/m2 on d1-5; gemcitabine 800mg/m2 on d1,8; pegaspargase 2500 IU/m2 on d1; 21 days per cycle)or SMILE regimen (methotrexate 2g/m2 on d1; dexamethasone 40mg/m2 on d2-4; ifosfamide 1500mg/m2 on d2-4; L-asparaginase 6000 U/m2 on d3-9; etoposide 100 mg/m2 on d2-4; 21 days per cycle) for up to 6 cycles unless disease progression, unacceptable toxicity or patient rejection. Efficacy was evaluated every two cycles. The primary endpoint was progression-free survival (PFS), and secondary endpoints included overall response rate (ORR) and overall survival (OS). In addition we compared the safety and tolerability between DDGP and SMILE regimens. The Kaplan-Merier method was used to evaluate for survival of freedom from events, and the log-rank test was used to evaluate differences among two groups. Results: A total of 87 eligible newly diagnosed advanced ENKTL patients were randomly assigned for the study and 80 patients were included into intention-to-treat population (40 patients in DDGP group and 40 patients in SMILE group). Data were collected from January 2011 to February 2019. Baseline characteristics of the two group patients were well balanced. At median follow-up of 41.5 months, the median PFS and OS in the SMILE group were 6.83 months and 75.2 months, respectively, while the median PFS and OS in the DDGP group have not been reached (Fig 1). The 3-year PFS rate and 5-year OS rate in DDGP group were higher than in SMILE group (56.6% vs. 41.8% for 3-year PFS, P=0.004; 74.3% vs. 51.7% for 5-year OS, P=0.02). No difference of the complete remission (CR) rate was observed between two groups, while overall response rate (ORR) in DDGP group was higher than in SMILE group (90.0% vs. 60.0%, p=0.002) (Table 1). More frequently 3/4 grade hematologic toxicities such as leucopenia and netropenia were observed in SMILE group than in DDGP group (p=0.022, p=0.015). Non-hematologic toxicities included elevated transaminase, mucositis and allergy were higher in SMILE group than in DDGP group(p=0.027, p&lt;0.001, p=0.024). Pancreatitis occurred in 2 patients in SMILE group, but not in DDGP group (Table 2). In addition, treatment-related deaths rate was up to 17.5% in SMILE regimen which was mainly caused by infection and hemorrhage due to bone marrow suppression. Such event was only 10% in DDGP regimen. Conclusion: DDGP regimen produced prolonged survival, better tolerability and safety than SMILE regimen in newly diagnosed advanced ENKTL. Disclosures No relevant conflicts of interest to declare.

Purpose Romidepsin is a structurally unique, potent class 1 selective histone deacetylase inhibitor. The primary objective of this international, pivotal, single-arm, phase II trial was to confirm the efficacy of romidepsin in patients with relapsed or refractory peripheral T-cell lymphoma (PTCL). Patients and Methods Patients who were refractory to at least one prior systemic therapy or for whom at least one prior systemic therapy failed received romidepsin at 14 mg/m2 as a 4-hour intravenous infusion on days 1, 8, and 15 every 28 days. The primary end point was the rate of complete response/unconfirmed complete response (CR/CRu) as assessed by an independent review committee. Results Of the 131 patients enrolled, 130 had histologically confirmed PTCL by central review. The median number of prior systemic therapies was two (range, one to eight). The objective response rate was 25% (33 of 130), including 15% (19 of 130) with CR/CRu. Patient characteristics, prior stem-cell transplantation, number or type of prior therapies, or response to last prior therapy did not have an impact on response rate. The median duration of response was 17 months, with the longest response ongoing at 34+ months. Of the 19 patients who achieved CR/CRu, 17 (89%) had not experienced disease progression at a median follow-up of 13.4 months. The most common grade ≥ 3 adverse events were thrombocytopenia (24%), neutropenia (20%), and infections (all types, 19%). Conclusion Single-agent romidepsin induced complete and durable responses with manageable toxicity in patients with relapsed or refractory PTCL across all major PTCL subtypes, regardless of the number or type of prior therapies. Results led to US Food and Drug Administration approval of romidepsin in this indication.

Purpose To determine the efficacy and safety of bendamustine as a single agent in refractory or relapsed T-cell lymphomas. Patients and Methods Patients with histologically confirmed peripheral T-cell lymphoma (PTCL) or cutaneous T-cell lymphoma who progressed after one or more lines of prior chemotherapy received bendamustine at 120 mg/m2 per day on days 1 through 2 every 3 weeks for six cycles. The primary end point was overall response rate (ORR). Secondary end points were duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Results Of the 60 patients included, 27 (45%) were refractory to their last prior chemotherapy, and the median duration of the best previous response was 6.6 months. Histology was predominantly angioimmunoblastic lymphadenopathy and PTCL not otherwise specified. The disease was disseminated in the majority of patients (87%). The median number of previous lines of chemotherapy was one (range, one to three). Twenty patients (33%) received fewer than three cycles of bendamustine, mostly because of disease progression. In the intent-to-treat population, the ORR was 50%, including complete response in 17 patients (28%) and partial response in 13 patients (22%). Bendamustine showed consistent efficacy independent of major disease characteristics. The median values for DoR, PFS, and OS were 3.5, 3.6, and 6.2 months, respectively. The most frequent grade 3 to 4 adverse events were neutropenia (30%), thrombocytopenia (24%), and infections (20%). Conclusion Bendamustine showed an encouraging high response rate across the two major PTCL subtypes, independent of age and prior treatment, with acceptable toxicity in refractory or relapsed T-cell lymphoma.

Frequent Relapses

Patients with angioimmunoblastic T-cell lymphoma (AITL), one of the most common types of peripheral T-cell lymphoma (PTCL), typically present with advanced disease, systemic symptoms, and immune deregulation. Treatment can be challenging owing to frequent relapses after initial and subsequent therapy. The front-line treatment approach currently mirrors the approach used for other nodal PTCLs with cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy and consideration for autologous stem-cell transplant (SCT). In the relapsed and refractory settings, allogeneic SCT offers the chance for long-term remission. Choice of treatment of relapsed or refractory disease depends on whether an allogeneic SCT is planned. Agents with preferential activity in relapsed or refractory AITL include epigenetic modifiers such as histone deacetylase inhibitors and hypomethylating agents. Other targeted agents show promise in AITL, including brentuximab vedotin and phosphoinositide-3-kinase inhibitors. Ongoing studies are evaluating new potential targets for AITL, with particular focus on identifying markers of response and resistance. Additional studies are assessing incorporation of novel agents into the front-line treatment of AITL. These studies will lead to more individualized treatment approaches and, ultimately, improved outcomes for patients with AITL.
