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.

8026 Background: T-cell lymphomas have a poor prognosis with few options of effective treatment. This study determined the efficacy and safety of bendamustine as a single agent in the treatment of refractory or relapsed T-cell lymphomas. Methods: Patients with histologically confirmed peripheral T-cell lymphoma (PTCL) or cutaneous T-cell lymphoma (CTCL), who had previously received at least one line of chemotherapy were selected. Bendamustine was administered IV at the dosage of 120 mg/m2 on days 1 and 2 every 3 weeks, for 6 cycles. Treatment response was assessed using the IWC for non-Hodgkin's lymphoma. 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), NCT00959686. Results: Twenty two female and 38 male were included. The median age was 66 years with more 1/4 of them > 75. Histology was predominantly angio-immunoblastic lymphadenopathy (n=32) and PTCL-nos (n=23). The median previous line of chemotherapy was 1 (1-3). Nearly one half (45%) of the patients was refractory to the last previous chemotherapy and the median duration of the best previous response was 6.6 (1.5-67) months. The disease was disseminated in the majority of case (87%) and the international prognostic index (IPI) was high (3–5) in 68% of the patients. Twenty patients (33%) received less than 3 cycles of bendamustine. The major reason for early discontinuation was disease progression. In the Intent-To-Treat (ITT) population, the best ORR was 50%, including complete response (CR) in 28% and partial response (PR) in 22 %. Bendamustine showed a consistency in the efficacy as a function of major disease characteristics. The median values for DoR, PFS and OS were 3.5, 4 and 6 months respectively. The most frequent grade 3/4 AEs were neutropenia (30%), thrombocytopenia (24%) and infections (20%). Conclusions: Bendamustine is active in high risk refractory and relapsed T-cell lymphoma with manageable toxicity.

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.

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.

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.

Abstract Abstract 1791 Background Advanced stage T-cell or NK/T-cell lymphomas usually show aggressive clinical course and their treatment outcomes are worse than B-cell non-Hodgkin lymphoma. Furthermore, the optimal treatment regimen is not still established for these disease entities. At present, cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) regimen is still used as a primary treatment for advanced stage T or NK/T cell lymphomas although its efficacy is not satisfactory. Thus, more effective treatment regimen is required to improve treatment outcome. The incorporation of new targeted agents into CHOP regimen has been a widely used strategy to develop new regimen for the treatment of lymphoma. Bortezomib, a proteasome inhibitor approved for the use of treatment of multiple myeloma has been tried in many B-cell non-Hodgkin lymphomas. A recent in vitro study results showed that proteasome inhibitor could inhibit the growth of NK/T lymphoma cells. Based on these results, we designed a regimen combining CHOP with. Our previous phase I study determined the maximum tolerated dose of bortezomib as 1.6mg/m2 for combination with CHOP. Thus, we performed the phase II study to evaluate the efficacy of bortezomib plus CHOP chemotherapy. Methods We enrolled patients with newly diagnosed T or NK/T cell lymphoma. All patients were Ann Arbor stage III/IV and had adequate organ function. Patients received bortezomib on days 1 and 8 (weekly schedule, 1.6 mg/m2 per dose) in addition to 750 mg/m2 cyclophosphamide, 50 mg/m2 doxorubicin, 1.4 mg/m2 vincristine on day 1 and 100 mg/day prednisolone on days 1 to 5, every 3 weeks. Six cycles of therapy administered every 21 days were planned. All patients provided written informed consents and this trial was registered at www.ClinicalTrials.gov (NCT00374699). Results 46 patients were enrolled between April 2007 and August 2009. Peripheral T-cell lymphoma, unspecified (n=16) and extranodal NK/T cell lymphoma (n=10) were dominant subtypes while angioimmunoblastic T-cell lymphoma (n=8) and ALK-negative anaplastic large cell lymphoma (n=6) account for 30.4% of all patients. Five patients with cutaneous T-cell lymphoma and one hepatosplenic T-cell lymphoma were also recruited. The median age at diagnosis was 52 years (range 21 – 66 years). Serum LDH elevation (n = 28, 60.9%) and stage IV patients were dominant (n = 32, 69.6%). Thus, the International Prognostic Index risk was dominantly high or high-intermediate (n = 26, 56.5%). Complete response was achieved in 30 patients (65.2%) and partial response was 5 patients (10.9%). As a result, the overall response rate was 76.1%. The comparison of complete response rate based on the subtype demonstrated that the complete response rate of peripheral T-cell lymphoma, unspecified (12/19, 63.2%), angioimmunoblastic T-cell lymphoma (6/8, 75%), anaplastic large cell lymphoma (4/6, 66.7%) and cutaneous T-cell lymphoma (5/5, 100.0%) was better than extranodal NK/T cell lymphoma (3/10, 30.0%). Five patients with extranodal NK/T cell lymphoma progressed during the treatment with bortezomib and CHOP. The hematologic toxicity was the major toxicity of this regimen, thus, grade 3/4 leucopenia and febrile neutropenia were the most frequent toxicity. However, there was no treatment-related mortality. In addition, neurotoxicity was tolerable, so the majority of peripheral neurotoxicity was grade 1 or 2. Conclusion The combined treatment of bortezomib with CHOP is an effective regimen for advanced stage T-cell lymphomas with acceptable toxicity. However, it may not be efficient for advanced stage extranodal NK/T-cell lymphomas. Disclosures: No relevant conflicts of interest to declare.

Abstract Background:T cell lymphomas account for 10-15% of lymphoid malignancies and display significant heterogeneity. T cell lymphomas have a worse prognosis than most B cell lymphomas. For relapsed or refractory disease, there is not a standard treatment and median progression free and overall survival rates have been reported as 3.7 and 6.5 months, respectively. Therefore, optimal treatment for relapsed/refractory T cell Non-Hodgkin Lymphoma (NHL) is an unmet clinical need. CPI-613 is a lipoate derivative that has shown activity in hematologic malignancies. CPI-613 selectively targets the pyruvate dehydrogenase complex (PDC) and α-ketoglutarate dehydrogenase complex (KGDHC) in tumor cells. CPI-613 leads to the inhibition of the catalytic and regulatory functions of the PDC and the KGDHC causing alterations of mitochondrial enzyme complex activities and altering redox status, leading to apoptosis, necrosis and autophagy of tumor cells. The anti-tumor activity of CPI-613 is evident in various cancer cell lines, xenograft animal tumor models and clinical trials against a diverse group of cancers. Patients tolerate CPI-613 as a single agent at doses up to 3,000 mg/m2, according to Phase 1 trials in patients with solid tumors and hematologic malignancies. Bendamustine has shown single agent activity in the relapsed lymphoma setting with response rates of approximately 50% for T cell NHL. Here, we are conducting a Phase I study in which the primary objective was to evaluate the maximum tolerated dose (MTD) of CPI-613 while administered in combination with Bendamustine. The secondary objective was to determine response rate to treatment. Methods: This study is a phase 1, open label, modified 3+3 dose escalation clinical trial evaluating CPI-613 and Bendamustine combination therapy. CPI-613 was given at escalating doses starting at 2,000mg/m2 over 2 hrs on days 1-4, and on days 8, 11, 15 and 18. Bendamustine was infused at 90 mg/m2 on days 4 and 5 of each treatment cycle. Each treatment cycle was 4 weeks and repeated up to six cycles. Demographics, patient characteristics and dose levels are shown in the table below. There was no intra-patient dose escalation. Results: As of July 27, 2016, eight subjects have received at least one dose of study drug. Eight patients are evaluable for safety and five patients are evaluable for response. The most common grade 3 or higher toxicities were lymphopenia and neutropenia and occurred in 4 subjects. One patient dosed at 2750 mg/m2 had a dose limiting toxicity of grade 3 acute kidney injury and grade 4 lactic acidosis. The protocol was later amended to discontinue dose escalation at doses of 2750 mg/m2 or higher and to expand the 2500mg/m2 cohort. The overall response rate was 80%. Three patients with peripheral T cell lymphoma, NOS, obtained a complete response and 1 patient with mycosis fungoides had a partial response. One patient with T cell acute lymphomoblastic lymphoma had progressive disease. The median time to response is 1.8 months. Enrollment is ongoing and updated trial results will be presented. Conclusions: This first reported study of CPI-613 administration in combination with Bendamustine in subjects with relapsed or refractory T cell lymphoma showed a good safety profile and an excellent overall response rate of 80% with CRs in all three patients with peripheral T cell lymphoma, NOS. Although numbers are small, continued investigation is warranted as these response rates in a poor risk population of patients with relapsed/refractory T cell lymphoma are very exciting. Clinical trial: NCT02168907 Disclosures No relevant conflicts of interest to declare.

Abstract Cutaneous T-cell lymphomas are disfiguring malignant lymphoproliferative disorders for which standard therapy has been principally palliative. 2-Chlorodeoxyadenosine (2-CdA), a new purine analogue resistant to degradation by adenosine deaminase that has substantial activity against lymphoid neoplasms, was administered to 16 patients with cutaneous involvement by T-cell lymphoma. All patients had failed topical treatment modalities and/or systemic therapies. Fifteen patients were evaluable; one patient was not evaluable due to incomplete therapy and follow-up. The overall response rate was 47%. Three of 15 patients (20%) achieved complete responses and four of 15 patients (27%) achieved partial responses. The median duration of response was 5 months. One patient remains in unmaintained complete remission at 52+ months. Therapy was well tolerated. Myelosuppression was the principal toxicity encountered, occurring in 8 of 15 (53%) patients. 2-CdA is an effective new agent for the treatment of cutaneous T-cell lymphoma and warrants further study both as a single agent and in combination regimens.

Abstract Introduction Brentuximab vedotin, an antibody drug conjugate comprising of an anti-CD30 monoclonal antibody (cAC10) attached by a protease-cleavable linker to a microtubule-disrupting agent monomethyl auristatin E (MMAE), was approved for relapsed Hodgkin lymphoma (ORR 75%) and systemic anaplastic large T-cell lymphoma (ALCL; ORR 86%) and the naked cAC10 antibody was shown active in CD30+ skin lymphomas (ORR 70%). Study design To determine safety and activity of Brentuximab vedotin we completed a Phase II open-label trial of 48 patients with primary cutaneous CD30+ lymphoproliferative disorders including lymphomatoid papulosis (LyP) and primary cutaneous pc-ALCL (pc-ALCL) or CD30+ mycosis fungoides (MF). Eligibility required skin lesion expression of CD30, > 10 Lyp lesions, one or more tumors, and need for systemic therapy. Patients with CD30+ MF were stage IB or higher and had received one or more prior topical or systemic therapies. The antibody conjugate was infused at 1.8 mg/kg every 21 days. Patients achieving a complete response (CR) received two additional doses and those achieving partial responses (PR) after 8 cycles could receive up to 16 doses. Response criteria for LyP were a 50% decrease in lesions, for pc-ALCL were 50 % tumor reduction, and for MF were 50% decrease in modified skin weighted assessment tool mSWAT. CD30 pretreatment skin biopsies and serum sCD30 were correlated with response. Results The 48 evaluable patients who received >2 doses of brentuximab vedotin included 22 females and 26 males with median age of 59.5 years (range 31-86). Their clinical diagnoses are in Table 1: 28 with MF, 2 with pc-ALCL, 9 with only LyP, 7 LyP with MF, and 2 with pc-ALCL/LyP/MF. Overall response rate (ORR) was 71% (34/48) with CR of 35% (17/48). The intent to treat response rate for all 56 patients receiving at least one dose was 61% (34/56). ORR was 50% in 28 MF patients regardless of whether their lesions had low, medium, or high CD30 at baseline. LyP and pc-ALCL patients had a 100% ORR and two pc-ALCL patients had CRs. For LyP, time to response (TTR) was 3 wks (range 3-6) and median duration of response (DOR) of 23 wks (range 6-44). For MF, TTR was 10.5 wks (range 3-39) and DOR was 13.5 wks (range 3-56 wks). Relapse rates in Lyp and pc-ALCL was 40% (8/20) with TTR of 25 wks (range 6-41). In MF responders, 5/14 (36%) relapsed and MTR was 3 wks (range 3-40). Median ORR and disease specific response (DSS) were not reached from date of diagnosis or from first dose. Median progression free survival (PFS) was 9.7 years from diagnosis and 1.68 years from first dose. Soluble CD30 levels from baseline to end of study differed significantly among those patients achieving a CR compared to those with PR or SD (p=.036). The most common related adverse event (AE) of any grade was peripheral neuropathy (PN) in 29/48 (60%): resolved in 14/29 (48%) and ongoing in 15/29 (52%) with 5 grade 2 and 10 grade one. Other AE > 10% were drug rashes (27%), diarrhea (24%), fatigue (30%), alopecia (16%), myalgias (16%), and nausea (14%). Grade 3-4 events included 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 for grade 2 neuropathy (n=2), transaminitis (n=1) and arthralgia/ fatigue (n=2). There were two deaths from untreated sepsis after one dose. Conclusion This phase II clinical trial demonstrates that brentuximab vedotin is active for mycosis fungoides (ORR 50%) irrespective of level of CD30+ expression. The ORR was 100% for CD30+ pc-ALCL, and LyP patients and was 71% with a CR of 36% for all evaluable patients. Disclosures: Duvic: Seattle Genetics: Research Funding. Off Label Use: This is an open label study for Cutaneous T-cell lymphoma and lymphoproliferative disorder. Brentuximab is approved for relapsed and refractory Hodgkins lymphoma.

Abstract Background. BV, an anti-CD30 antibody-drug conjugate, has been approved for the treatment of Hodgkin lymphoma (HL) and ALCL. Of interest, BV has shown activity in PTCLs other than ALCL that express low or even undetectable levels of CD30. In particular BV has been reported effective in angioimmunoblastic T-cell lymphoma (AITL) and peripheral T-cell lymphoma not otherwise specified (PTCL-nos). Here, we report 4 cases with relapsed/resistant PTCLs (1 AITL, 1 NK-T nasal type, 1 PTCL with T-helper follicular phenotype-PTCL-TFH and 1 PTCL-nos) who responded to BV therapy. Results. On August 2014, a 53-y-old caucasian male was diagnosed with 5% CD30-positive AITL. The final stage was IIIA, because of a single left axillar node was documented at the PET-TC scan in addition to the excised inguinal lymphadenopathy. A complete metabolic PET remission (PET-CR) was documented after the 3th and confirmed after the 6th cycle of cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone (CHOEP). However, relapsing disease was documented 6 mths later. At that time, diffuse over and under-diaphragm nodal involvement was observed. A PET-CR was achieved after 2 cycles of dexamethasone, cytarabine, and cisplatin (DHAP), but disease progressed shortly after the 4th cycle before the planned autotransplantation (ASCT). A 3th line chemotherapy, consisting of mitoxantrone and high dose ARA-C (modified HAM), was performed and failed to control the disease. Furthermore HAM chemotherapy was associated with severe infectious complications (sepsis from MDR S. Epidermidis and pulmonary aspergillosis). On December 2015, BV was begun. A PET-CR was documented after the 4th and confirmed after the 8th cycle of therapy. The patients is still in CR, in continuous therapy (12th cycle), waiting for HLA matched unrelated donor. On July 2012 a 62-y-old caucasian man was diagnosed with extranodal NK/T-cell nasal type lymphoma. Both Epstein Barr virus (EBV) and CD30 molecule were not expressed by neoplastic cells. Weekly cisplatin and radiotherapy were concomitantly given followed by 3 cycles of etoposide, ifosfamide, cisplatin and dexamethasone. This treatment resulted in PET-CR. At the time of first relapse (Nov 2013), 3 cycles of methotrexate, L-asparaginase and dexamethasone, followed by ASCT (fotemustine, etoposide, cytarabine, melphalan), induced a 2nd PET-CR. However, two subsequent PET evaluations suggested the presence of active disease shortly after (December 2015) a biopsy proven relapse was documented. A PET-CR was observed after 2 and confirmed after 7 cycles of single agent BV. The patient is still undergoing treatment. On September 2015, a 49-y-old african man was diagnosed with PTCL-THF, showing AITL signs, with both EBV and CD30 positive (50-75%) Hodgkin/Reed-Sternberg cells. A progressive disease was documented after the 4th cycle of CHOEP. At that time, patient was not candidate to receive further chemotherapy, because of worsening of perfomance status (PS). BV, given as salvage therapy, resulted in a rapid control of all signs and symptoms after the 6th administration. Because of improved PS and a partial metabolic remission, the DHAP combination was begun on June 2016 and ASCT is now planned as consolidation. On November 2009, a 46-y-old caucasian man was diagnosed with classical HL. The final stage was IEA. The disease was refractory to doxorubicin, bleomycin, vinblastine, dacarbazine and radiotherapy. A PET-CR was achieved in response to ifosfamide, gemcitabine, vinorelbine and prednisone chemotherapy. After 3 yrs, a lymph node biopsy confirmed a relapsed HL. Four cycles of DHAP followed by ASCT resulted in a 2nd PET-CR. After 3 mths, a PTCL-NOS associated with blastic lymphoid B EBV positive cells was diagnosed on an excisional lymph node biopsy. On May 2014 BV as single-agent was started. A PET-CR lasted for 8 mths. Relapsing disease was documented on January 2015. The patient refused further chemotherapy and died because of disease progression on July 2015. Conclusion. In this experience BV, regardless of CD30 expression, has shown significant clinical activity in recurrent or refractory T-cell lymphomas and no significant toxicity, even in heavily pretreated patients. In consideration of the BV activity in PTCLs, combination studies with other molecules, such as romidepsine, are desirable. Disclosures No relevant conflicts of interest to declare.

PURPOSE: To evaluate the efficacy and toxicity of gemcitabine, a novel pyrimidine antimetabolite with a low-toxicity profile and activity in several solid tumors, in patients with relapsed or refractory cutaneous T-cell lymphomas. PATIENTS AND METHODS: Between May 1997 and February 1999, 44 previously treated patients with mycosis fungoides (MF; n = 30) and peripheral T-cell lymphoma unspecified (PTCLU) with exclusive skin involvement (n = 14) were enrolled onto a two-institution, phase II trial and treated with gemcitabine. This drug was given on days 1, 8, and 15 of a 28-day schedule at a dose of 1,200 mg/m2 intravenously over 30 minutes for a total of three courses. RESULTS: Of the 44 patients, five (11.5%) achieved complete responses (CRs), 26 (59%) partial responses (PRs), and the remaining 13 showed no benefit from the treatment. Two of the CRs were histologically confirmed. The CR and PR rates were the same for patients with MF and those with PTCLU, respectively. No difference in terms of overall response rate was observed between relapsed and refractory patients. The median durations of CR and PR were 15 months (range, 6 to 22 months) and 10 months (range, 2 to 15 months), respectively. Treatment was well tolerated; hematologic toxicity was mild, and no nausea/vomiting or organ toxicity was recorded. CONCLUSION: The results of the present phase II study show activity of gemcitabine as a single agent in patients with pretreated cutaneous T-cell lymphoma. Further studies that use gemcitabine alone or in combination with other drugs in earlier stages of the disease are needed.
