Abstract Brentuximab vedotin (BV) is an antibody drug-conjugate targeting CD30 linked to monomethyl auristatin E. Several studies have shown the efficacy of BV in patients with refractory or relapsed Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (sALCL). We reviewed our clinical database to evaluate the long-term efficacy of this treatment. From July 2009 to February 2015, 57 patients were treated with BV in our Institute: 43 with a diagnosis of HL and 14 with sALCL. Thirty-six were males and 21 were females, with a median age of 33 years (range 16-77). All of them had been heavily pretreated before BV with a median number of previous therapies of 3 (range 2-10). Thirty-nine had refractory disease and 18 were relapsed. Autologous stem cells transplantation had failed in 30 patients. BV was administered at a dosage of 1.8 mg/mq, every 21 days, for a maximum of 16 cycles. The median number of cycles was 8 (range 2-16); 13 patients completed the entire schedule. The best overall response rate was globally 57,8% (33 of 57 patients), including 25 (43.8%) complete responses (CR): 18 with HL and 7 with sALCL. At present, 20/25 (80%) patients are still in continuous CR (CCR) with a median follow up of 9 months (range 3-41): 10 of them have consolidated the response with a stem cell transplantation (SCT) (4 auto-SCT and 6 allo-SCT) and 10 patients have remained in CR without any other therapy after BV. Among these long-term responders without any consolidation (7 patients with HL and 3 with sALCL), the median follow-up is 12 months (range 3-37); in particular there are 3 patients in CCR after at least 24 months. The global overall survival rate at 68 months is 71% (no patients with sALCL dead) and the median overall survival has not been reached yet. The global progression-free survival rate at 48 months is 30%, the median is achieved at 11,7 months. Toxicity was primarily neurological with peripheral sensory symptoms (30%) and motor neuropathy (5%); the majority was grade 3 in severity (8 patients). This study confirms the safety and the high efficacy of BV that can be considered an effective treatment in patients with relapsed or refractory HL or sALCL. This drug can induce a durable complete response representing a "bridge" to auto-SCT or allo-SCT. However our data show a subset of patients that can be considered "long-term responders", who have remained in CCR without any consolidation after BV.

Background. Anaplastic lymphoma kinase positive systemic anaplastic large cell lymphoma (ALK+ ALCL) represents an aggressive T-cell malignancy that primarily affects children and younger adults. Upon treatment with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) or CHOP-like regimens its prognosis is relatively favourable compared to other aggressive T-cell lymphomas, however, the rare event of disease reoccurrence remains particularly challenging. ALCL is CD30 positive, and mono treatment with brentuximab vedotin (BrV) can achieve long term remissions in only few relapsed patients not receiving consolidating stem cell transplantation (Pro B. et al. Blood 2017). A subset of ALCL patients express platelet derived growth factor receptor (PDGFR) alpha or beta in their tumour cells which is induced by ALK via AP-1 transcription factor activation. We previously demonstrated that PDGFR blockade by the Abl/c-Kit/PDGFR kinase inhibitor imatinib is an effective treatment concept for ALK+ ALCL in experimental mouse models (Laimer D. et al. Nature Med. 2012). Here we aimed to assess the prognostic value of PDGFR expression and to probe the clinical value of its targeting by imatinib in ALK+ ALCL patients. Methods. The impact of PDGFR expression to predict clinical outcome was analyzed in samples of 98 ALK+ ALCL patients included in the studies NHL-BFM 90, 95 and ALCL99 between 1992 and 2006. Six patients (age 18-45) with chemo-refractory ALK+ ALCL were prospectively treated with imatinib plus (4) or minus (2) BrV. 33% (2/6) had previously received salvage treatment with stem cell transplantation (SCT). Three of the patients had been enrolled in a prospective single-arm study combining imatinib and BrV, a trial that was terminated due to poor patient recruitment (AGMT ALCL1 trial, EudraCT No.: 2013-003505-26, supported by Takeda®). PDGFR alpha and beta expression analyses were performed on tumour samples of treated patients. Results. ALK+ ALCL patients with high PDGFR expression on tumor cells (n=11) had a significantly lower event-free survival rate (EFS) at 5 years compared to patients with no or low expression (n=87) (27±13% versus 70±5%, respectively, p<0.001, figure 1a). Four of the six patients with relapsed/ refractory ALK+ ALCL responded to imatinib +/- BrV with a rapid metabolic complete remission (CR). At a median clinical follow-up of 52 months (range 20 to108) all responding patients demonstrated an ongoing CR without SCT even after imatinib was discontinued with an average time on imatinib of 49 weeks (range 32 to 130; figure 1b). Half (2/4) of responding patients received no or only 1 infusion of BrV; both non-responding patients had received BrV. Importantly, despite the few patients that could be prospectively treated, PDGFR expression status had a significant impact on clinical course. All patients (4/4) who expressed either PDGFR alpha or beta in tumour cells and in the lymph node microenvironment responded with an ongoing metabolic CR, whereas the two patients whose lymphoma cells had negative PDGFR expression failed to respond (EFS: 4 versus 210 weeks, p = 0.018; figure 1c). Conclusions. 1) PDGFR expression is a poor risk factor in ALK+ ALCL. 2) Imatinib alone or in combination with BrV overcomes chemo-resistance conferred by PDGFR expression. 3) Imatinib treatment can be discontinued with ongoing CR. 4) These observations suggest that PDGFR expressing ALK+ ALCL patients might benefit from early treatment with imatinib.

Background: Patients with r/r tumor stage CTCL and/or PTCL have a poor prognosis. BV is currently FDA approved for CD30 positive CTCL and anaplastic large cell lymphoma (ALCL) with single agent activity in additional PTCL subtypes. Len also has single agent activity in patients with r/r CTCL/PTCL. The safety of the combination was established in a phase I trial in patients with r/r diffuse large B-cell lymphoma. Methods: We conducted a single-institution phase II trial to determine the safety and efficacy of BV+Len combination in patients with r/r CTCL/PTCL. Simon's 2-stage optimal design was followed to test the null hypothesis of overall response rate (ORR) ≤0.3 versus the alternative hypothesis of ORR≥0.5. Patients with ≥ 1 line of systemic therapy or 2 lines of skin directed therapy, at least stage IB (for CTCL), and no prior progression on BV were eligible regardless of CD30 staining. All patients were treated with BV 1.2 mg/kg IV and Len 20 mg PO daily q3 weeks for a maximum 16 cycles. After 7 patients were treated, we reduced Len to 10 mg given safety/tolerability concerns. Responses are assessed by the International Society for Cutaneous Lymphomas and the cutaneous lymphoma task force of the European Organization of Research and Treatment of Cancer (ISCL/EORTC) Global response criteria (for CTCL) and Cheson year criteria (for PTCL). The effect of treatment on quality of life is assessed by Skindex-16. Results: As of July 1, 2019, 17 subjects were treated; 10 (59%) with mycosis fungoides (MF), 2 (12%) with Sezary syndrome (SS), 2 (12%) with CD30+ lymphoproliferative disorder, and 3 (18%) with PTCL. Median age was 60 (49-90) years and 76% were males. CD30 was completely negative (<1%) in 3 (18%) of patients and median CD30 staining (by immunohistochemistry) was 7.5% (range 1-75%). Of 12 patients with MF/SS, 5 (42%) had evidence of large cell transformation at accrual. Of 14 patients with CTCL, median baseline mSWAT was 54.5 (range 4.4-190). Median number of prior therapies was 5 (range 1-9). Grade 3 adverse events (AEs) were reported in 11/17 patients; including neutropenia (4), thrombocytopenia (1), bronchitis (1), dyspnea (1), abdominal pain (2), vertigo (1), , DRESS (Drug Rash with Eosinophilia and Systemic Symptoms) syndrome (1), urinary tract infection (1), and tumor flare (2). Median number of cycles received was 4 (range 1-17). Best response in 14 evaluable patients were 2 (14%) complete response, 3 (21%) partial response, and 8 (57%) stable disease with ORR of 33% (95% confidence interval:12-62%). Of 17 patients, 5 (29%) remain on treatment, and 12 (71%) discontinued treatment because of disease progression (7; 58%), AEs (4; 33%), or patient preference (1; 2%). Median duration of response was 3.2 (range 2.5-13) months. Of note, 7/14 patients (50%) patients with CTCL had >50% reduction in their Skindex-16 scores after a median of 2 cycles (range 1-3). Conclusions: BV + Len is combination is safe and efficacious in a heavily pre-treated patients with T-cell lymphomas. Len doses higher than 10 mg daily are poorly tolerated and associated with excess tumor flare. Recruitment of both CTCL and PTCL patients for this trial is ongoing.

Abstract From November 2012 to July 2014, brentuximab vedotin (BV) was available in Italy for patients with relapsed systemic anaplastic large cell lymphoma (ALCL) outside a clinical trial context based on a local disposition of the Italian Drug Agency (AIFA) issued according to a national law (Law 648/96: "medicinal products that are provided free of charge on the national health service"). A large Italian observational retrospective study was conducted on the use of BV in the everyday clinical practice to check if clinical trial results are confirmed even in a real life context. Primary endpoint was the best response; secondary endpoints were the overall response rate at the end of the treatment, duration of response, survival and the safety profile. BV was infused intravenously at the dose of 1.8 mg/kg every 3 weeks for a maximum of 16 cycles. A total of 40 ALCL (18 anaplastic lymphoma kinase [ALK] negative and 22 ALK-positive status) patients were treated with BV in 40 Hematology Centers. All patients had histologically documented CD30+ ALCL; 16 (40%) had relapsed and 24 (60%) had refractory disease. Patients were heavily pretreated with a median of 2 previous therapies (including autologous transplant in the 32.5% of cases). Best response was observed after a median of 4 cycles in 31 patients (77.5%): 19 (47.5%) patients obtained a complete response (CR) and 12 (30%) achieved a partial response (PR); overall response rate at the end of the treatment was 62.5% (18 CR and 7 PR). The best response rate was higher in the elderly subset (>60 years): 9 (64.2%) CR and 3 (21.4%) PR, achieving a total of 85.6%. At the latest follow up 15/18 patients are still in CR (3 with consolidative procedure). Global progression free survival was 39.1% at 29 months and disease free survival 54% at 23.9 months (median not reached). Median duration of response was 12 months (range 9-24 months). We identified 5 long term responders (patients with a response ≥ 12 months), all were still in CR at the latest follow up (1 underwent allogeneic transplant). Particularly, all the long term responders were aged <30 years at first BV infusion. All patients were included in the safety profile for the analysis; in general, the treatment was well tolerated even in this real life context and the toxicity profile was closely similar to the previously published data; no death has been linked to BV toxicity. Toxicity was primarily neurological and rarely so serious as to require treatment reduction or interruption; furthermore, neurological toxicity always reversed completely after end of treatment. No long-term toxicity was assessed during the follow-up period, even in patients later subjected to transplant consolidation. BV induces clinical responses quite rapidly, i.e. within the first 4 cycles in most responders, thus permitting the timely application of the transplantation phase. Furthermore, BV displays a favorable toxicity profile, without overlapping toxicities with most of the agents employed in high-dose conditioning regimens. For patients ineligible for transplant or for who transplant failed, BV may represent a feasible effective therapeutic option in everyday clinical practice.

Anaplastic large cell lymphoma (ALCL) is an aggressive type of non-Hodgkin's lymphoma (NHL) comprising 2-8% of adult and 10-20% of pediatric and adolescent NHL. More than three-fourths of anaplastic lymphoma kinase (ALK)-positive ALCL express (nucleophosmin1) NPM1-ALK fusion gene as a result of t(2;5) chromosomal translocation. The self-dimerization of fusion kinase NPM1-ALK mediates constitutive activation of the chimeric tyrosine kinase activity leading to downstream signaling pathways responsible for lymphoma cell proliferation and survival. The current standard treatment regimen for ALK+ ALCL is CHOP (cyclophosphamide, hydroxy doxorubicin, vincristine, prednisone) chemotherapy. Oftentimes, resistance and failure of remission occur with CHOP therapy, making it a suboptimal treatment regimen for many patients. Therefore, an alternative therapeutic approach is warranted to better address the needs of the ALK+ ALCL population. Gilteritinib is a recently FDA approved tyrosine kinase inhibitor for the treatment of FMS-like tyrosine kinase (FLT3) mutation-positive acute myeloid leukemia. Along with inhibition of FLT3, gilteritinib also inhibits other tyrosine kinases such as AXL and ALK. In this study, for the first time, we demonstrated gilteritinib mediated growth inhibitory effects on NPM1-ALK driven ALCL cells. We have used a total of five cell lines in our study: NPM1-ALK endogenously expressing human ALCL cell lines (SUDHL-1, SUP-M2, SR-786, and DEL), and our laboratory generated ectopically overexpressing Ba/F3-FG-NPM1-ALK, a murine cell line. Gilteritinib treatment (5-20 nM) inhibited NPM1-ALK fusion kinase phosphorylation, which resulted in downregulation of downstream survival signaling pathways including AKT, ERK1/2, and STAT3 leading to induced apoptosis and decreased clonogenic survival. Gilteritinib mediated apoptosis was associated with caspase 3/9 and poly (ADP-ribose) polymerase cleavage with increased pro-apoptotic protein BAD and decreased anti-apoptotic protein MCL-1. Increased expression of c-Myc is associated with ALK-positive ALCL and gilteritinib treatment decreased c-Myc levels in a dose dependent manner. Cell cycle analysis demonstrated gilteritinib treatment induced cell cycle arrest at the G0/G1 phase with a concomitant decrease in G2/M and S phases. In summary, our preclinical results suggest gilteritinib has therapeutic potential for the treatment of ALCL cells expressing NPM1-ALK and other ALK /ALK-fusion driven hematologic or solid malignancies.

Abstract Introduction Previous results of an open-label, randomized, controlled, multicenter phase III study (DOXIL-MMY-3001) demonstrated that bortezomib+pegylated liposomal doxorubicin (PLD) was superior to bortezomib monotherapy in treating subjects with relapsed or refractory multiple myeloma (MM) whose disease had failed one or more lines of prior therapy. The risk of developing disease progression was significantly reduced by 45% with bortezomib+PLD (median time to progression (TTP) with bortezomib+PLD: 9.3 months, bortezomib: 6.5 months; HR=1.82, 95% confidence interval (CI) [1.41, 2.35]; p=0.000004). In the interim analysis, the 15-month overall survival (OS) rate for bortezomib+PLD was 76% (95% CI [70%, 83%]) compared with 65% (95% CI [58%, 73%]) for bortezomib alone (p=0.03)(Orlowski et al JCO 25: 3892-3901, 2007). A protocol-defined analysis of the final survival data of this study is provided here. Methods Subjects with confirmed MM, ECOG status 0 to 1, platelets ≥75,000/mm3, hemoglobin ≥8.0 g/dL, absolute neutrophils ≥1,000/mm3, and creatinine clearance ≥30 mL/min were randomized to bortezomib (bortezomib 1.3 mg/m2, intravenous, days 1, 4, 8, and 11 of an every 21-day cycle), or bortezomib+PLD (same bortezomib+PLD 30 mg/m2 intravenous on day 4). Randomization was stratified according to serum β2-microglobulin levels (≤2.5, >2.5 and ≤5.5, or >5.5 mg/L) and response to prior treatment (response followed by progression, or primary refractory). The primary endpoint was TTP; secondary efficacy endpoints included overall survival, progression-free survival (PFS) and overall response rate (complete response [CR] + partial response [PR]). Results A total of 646 subjects (bortezomib+PLD: 324; bortezomib: 322) were randomized between December 2004 and March 2006. In the pre-planned interim analysis, the study met its primary and other secondary end points. The study continued for long-term survival follow-up. At the clinical cutoff of 16 May, 2014, for the final survival analysis with a median follow-up of 103 months, 79% of subjects were dead (bortezomib+PLD: 253 [78%]; bortezomib: 257 [80%]), 6% withdrew consent, 4% were lost to follow-up, and 11% were still alive. Median OS in bortezomib+PLD–treated subjects was 33.0 months (95% CI [28.9, 37.1]) versus 30.8 months (95% CI [25.2, 36.5]) in bortezomib-treated subjects (HR=1.05, 95% CI [0.88, 1.25]; p=0.6068). The types of salvage therapies utilized included dexamethasone (49.1%), thalidomide (31.0%), cyclophosphamide (28.5%), melphalan (22.9%), lenalidomide (21.8%), bortezomib (20.4%) and doxorubicin (8.0%), which were well-balanced between the two treatment groups. Conclusion Despite inducing a superior TTP, long-term follow-up revealed that PLD+bortezomib-treatment did not improve the OS compared with bortezomib alone in subjects with relapsed or refractory MM. The inability to confirm the early survival advantage may be due to the effects of subsequent lines of therapy, and underscores the need for long-term follow-up of phase III trials.

In order to assess long-term outcome of patients with localized (stage I or II) diffuse large-cell lymphoma treated with initial combination chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without involved-field radiotherapy following chemotherapy, we combined data from two prospective trials in Tucson (64 patients) and Vancouver (78 patients). Follow-up on 142 patients was updated and a variety of potential pretreatment prognostic factors were analyzed for impact on outcome. One hundred forty patients (99%) achieved a complete remission and there were no differences in outcome between institutions. Twenty-three patients have relapsed and 22 have died from lymphoma at a median follow-up of 4.4 years, resulting in an overall relapse-free survival of 82% at 5 years. There was no treatment-related mortality and were no instances of late cardiac toxicity or leukemia. Of the following potential pretreatment prognostic factors (age, stage, "B" symptoms, extranodal disease, gastrointestinal tract involvement, bulky disease, or disease above or below the diaphragm), only stage affected relapse-free survival (RFS) (P = .16) and survival (.003). Among 34% of patients over age 65, outcome was similar to younger patients. RFS for 108 patients treated with CHOP plus radiotherapy was not significantly superior to the use of CHOP alone in 34 patients (P = .2).

Abstract Abstract 443 Background: Systemic anaplastic large cell lymphoma (sALCL) is a T-cell non-Hodgkin lymphoma (NHL) characterized by the uniform expression of CD30. sALCL accounts for 2–5% of all cases of NHL; approximately 40–65% of patients experience recurrent disease after frontline treatment with few effective treatment options. Brentuximab vedotin (SGN-35) comprises an anti-CD30 antibody conjugated by a protease-cleavable linker to the potent antimicrotubule agent, monomethyl auristatin E (MMAE). A phase 2 study was conducted to determine the efficacy and safety of brentuximab vedotin in patients with relapsed or refractory sALCL (ClinicalTrials.gov #NCT00866047); updated results of this trial are presented. Methods: Brentuximab vedotin 1.8 mg/kg was administered every 3 weeks as a 30-minute outpatient IV infusion for up to 16 cycles of treatment. Determination of efficacy was based on objective response assessments per independent review according to the Revised Response Criteria for Malignant Lymphoma (Cheson 2007). Patients were enrolled between June 2009 and May 2010 at 22 clinical sites in the US, Canada, and Europe. Results: 58 patients with a median of 2 prior therapies (range 1–6) were treated; 57% were male and the median age was 52 years (range 14–76). Seventy-two percent of patients had ALK-negative disease, 62% had primary refractory disease (defined as no complete remission (CR) or relapse within 3 months of frontline therapy), and 26% had failed a prior autologous stem cell transplant (SCT). As previously reported, the objective response rate (ORR) was 86%, the CR rate was 57%, and 97% of patients had a reduction in tumor volume postbaseline. At the time of this updated analysis (data cut May 2011), all but 2 patients had discontinued treatment with brentuximab vedotin; the median number of treatment cycles was 7 (range 1–16). The median duration of objective response was 13.0 months (range 0.1–19.1+) and the median duration of response for patients achieving a CR was 17.1 months (range 0.7–19.1+). Median progression-free survival (PFS) was 14.6 months and median overall survival was not yet reached. Per investigator assessment, the median PFS with brentuximab vedotin was significantly longer than the median PFS achieved with the most recent prior therapy (20.0 months vs. 5.9 months; P value <0.001). All subgroups of patients analyzed in the study achieved a similar level of antitumor activity, regardless of baseline disease characteristics, tumor burden, or prior treatment history. Responses were particularly noteworthy in patients who had never responded to any previous therapy (n=13); in this subgroup of patients, 10 achieved an objective response (77%) and 4 a CR (31%). After discontinuing treatment in the study, 16 patients (28%) received a hematopoietic SCT (8 allogeneic, 8 autologous). The most common adverse events observed in the study were peripheral sensory neuropathy (41%), nausea (40%), fatigue (38%), pyrexia (34%), diarrhea (29%), rash (24%), constipation (22%), and neutropenia (21%). Most AEs in the study were Grade 1 or 2 in severity. Ten patients (17%) experienced Grade 3 events of peripheral neuropathy as defined in a Standardised MedDRA Query; no Grade 4 events were observed. In patients with neuropathy, 79% (26 of 33) have experienced resolution or some improvement and the median time to resolution or improvement was 13.3 weeks (range 0.3–48.7). Conclusions: Durable complete remissions were achieved with brentuximab vedotin, and treatment was associated with manageable toxicity, in patients with relapsed or refractory sALCL. Approximately half of the responding patients (24 of 50) continued in remission at the time of this analysis; updated results of efficacy and long term safety will be presented at the meeting. Based on the results from this study, a trial evaluating the safety of brentuximab vedotin administered in sequence and in combination with multiagent chemotherapy was initiated and is currently ongoing in frontline sALCL.

Abstract Abstract 2745 Background: Systemic anaplastic large cell lymphoma (sALCL) is a CD30-positive malignancy that accounts for 2–5% of all non-Hodgkin lymphoma (NHL) cases. Approximately 40–65% of patients with sALCL develop recurrent disease after frontline treatment and few effective treatment options exist for this population. Brentuximab vedotin (ADCETRIS®) comprises an anti-CD30 antibody conjugated by a protease-cleavable linker to monomethyl auristatin E (MMAE), a microtubule-disrupting agent. Brentuximab vedotin selectively induces apoptotic death of CD30-positive cells by binding, internalizing, and releasing MMAE. A phase 2 study was conducted to determine the efficacy and safety of brentuximab vedotin in patients with relapsed or refractory sALCL (ClinicalTrials.gov #NCT00866047); long-term follow-up data from this ongoing trial are presented. Methods: Patients received 1.8 mg/kg brentuximab vedotin every 3 weeks as a 30-minute outpatient IV infusion for up to 16 cycles. The primary endpoint was the objective response rate (ORR) per independent review according to the Revised Response Criteria for Malignant Lymphoma (Cheson 2007). Results: 58 patients were enrolled at 22 clinical sites in the US, Canada, and Europe. The median age was 52 years (range 14–76) and 57% were male. 72% of patients had ALK-negative disease, 62% had primary refractory disease (defined as no complete remission [CR] or relapse within 3 months of frontline therapy), and 26% had failed a prior autologous stem cell transplant (SCT). As previously reported, the ORR was 86% (50 of 58 patients) and the CR rate was 59% (34 of 58 patients). At the time of this analysis (datacut April 2012), all patients had discontinued treatment and the median observation time from first dose was 22.8 months (range, 0.8–32.2). The median duration of objective response for all patients was 13.2 months (range, 0.1–27.7+) and the median duration of response for patients who obtained a CR has not yet been met (range, 0.7–27.7+). Of the patients who achieved a CR, over half (18 of 34; 53%) were in continued remission at the time of this analysis. The median progression-free survival (PFS) for all patients was 14.6 months and the median overall survival has not yet been reached. After discontinuing treatment in the study, 16 patients (28%) received a hematopoietic SCT (8 allogeneic, 8 autologous). The median PFS has not yet been met for the group of patients who achieved a CR and received a subsequent SCT (range, 8.1–29+), while the median PFS for the group who achieved a CR and did not receive post-treatment SCT was 18.4 months (range, 2.6–26+). All subgroups of patients analyzed in the study achieved a similar level of antitumor activity regardless of baseline disease characteristics, tumor burden, or prior treatment history. Median PFS did not appear to be influenced by ALK status; in the subgroup of ALK-positive patients (n=16) PFS was 14.6 months versus 14.3 months for ALK-negative patients (n=42). The median overall survival has not yet been met for either ALK-positive or ALK-negative patients. The most common (reported in ≥20% of patients) adverse events (AEs) observed in the study were peripheral sensory neuropathy (41%), nausea (40%), fatigue (38%), pyrexia (34%), diarrhea (29%), rash (24%), constipation (22%), and neutropenia (21%). The majority of AEs were Grade 1 or 2 in severity. Ten patients (17%) experienced Grade 3 events of peripheral neuropathy as defined by a Standardised MedDRA Query; no Grade 4 events were observed. Resolution or at least 1 grade of improvement in peripheral neuropathy has occurred in 79% of patients with neuropathy events (26 of 33 patients) and the median time to resolution or improvement was 13.4 weeks (range, 0.3–48.7). Conclusions: 34 of 58 patients (59%) with relapsed or refractory sALCL obtained a durable CR with brentuximab vedotin and treatment was associated with manageable toxicity. PFS did not appear to be influenced by ALK status. These long-term follow-up results underscore the durability of clinical benefit obtained with brentuximab vedotin. A randomized phase 3 study is planned to evaluate brentuximab vedotin in combination with cyclophosphamide, doxorubicin, and prednisone for frontline treatment of CD30-positive mature T-cell lymphomas.

Abstract Purpose: We assessed the survival outcome of patients with anaplastic large cell lymphoma (ALCL) who experienced disease progression or relapse after first line and subsequent therapy. We sought to evaluate the impact of brentuximab vedotin (BV), and survival outcome of patients with ALCL who experienced progression after BV. Patients and Methods: A total of 176 patients (74 ALK+, 102 ALK-) initially diagnosed between 1999 and 2014 were retrospectively analyzed. Progression-free survival (PFS) and overall survival (OS) after the progression/relapse following first-line chemotherapy (PFS1 and OS1), after first salvage therapy (PFS2 and OS2) and after second salvage therapy (PFS3 and OS3) were calculated. Outcome was separately analyzed according to the ALK status focusing on the use of BV. Results: The median age of the patients was 50 (range: 18-89). With a median follow up of 64 months, 111 patients (38 ALK+, 73 ALK-) experienced progression/relapse after the first-line therapy, of which 4 ALK- patients were post upfront stem cell transplant (SCT). Thirty and 15 patients eventually underwent autologous and allogeneic SCT after salvage chemotherapy, respectively. The median PFS1 and OS1 in patients with ALK+ALCL and ALK-ALCL were 8.4 and 28.5 months, and 13.1 and 47.7 months, respectively. In patients with ALK+ALCL, the median PFS1, PFS2 and PFS3 were 53.6, 5.2 and 2.3 months, respectively. The median OS1, OS2 and OS3 were not reached, 47.3 and 6.1 months, respectively. In patients with ALK-ALCL, the median PFS1, PFS2 and PFS3 were 12.9, 3.0 and 2.0 months, respectively. The median OS1, OS2 and OS3 were 54.3, 10.8 and 5.8 months, respectively. Interestingly, there were no significant difference in PFS2 between ALK+ALCL and ALK-ALCL. However, OS2 was significantly longer in patients with ALK+ALCL, suggesting possibly continued chemosensitivity of recurrent ALK+ALCL. A total of 30 patients received BV in 1st salvage (15 patients) and after 2nd salvage (15 patients).The use of BV at 1st salvage was associated with significantly longer PFS2 and OS2 both in patients with ALK-ALCL but not with ALK+ALCL likely due to small number of cases. Mutivariate analysis adjusting baseline PIT risk factors and the duration of the response to first line therapy revealed that use of BV (at any point in the salvage setting) is significantly associated with longer OS2 (HR: 0.43, 95%CI: 0.23-0.80). Overall, 12 patients experienced relapse/progression after BV treatment. The median OS after BV failure was 1.4 months (95%CI: 0.5-9.5 months) (Figure). Summary: Survival outcome for relapsed/refractory patients with ALK+ and ALK- patients is improved with BV. However, survival outcome after BV failure is very poor. A new treatment strategies to consolidate or maintain the response after BV and to develop more safe and better therapeutic options are needed. Figure 1. Figure 1.
