EORTC 21012: Phase II Multicentre Study of Caelyx™ Monotherapy In Patients with Advanced Mycosis Fungoides Stage IIb, Iva and IVb with or without Previous Chemotherapy.

Abstract Abstract 2823 Background: Cutaneous lymphomas consist of a heterogeneous group of diseases that are characterized by a clonal accumulation of lymphocytes in the skin. The estimated incidence is 1–2/100.000 per year. The more advanced stages have a poor prognosis and treatments are usually palliative, such as combination of PUVA with retinoids or recombinant interferon alpha. CHOP or COPBLAM are widely used in analogy to other peripheral T-cell lymphomas, but have severe, sometimes lethal infectious complications and short response duration. Some studies indicated response rates after CHOP chemotherapy regimen are between 40% and 70% in cutaneous T-cell lymphoma (CTCL). However, these studies include patients in various disease stages, that might not necessarily need aggressive treatment and without precise information concerning the CTCL subtype. Therefore, there is an urgent need for multicenter trials designed to test a clearly defined patient population. Pegylated liposomal doxorubicin (PLD, Caelyx™) is an antineoplastic antibiotic with pharmacologic actions similar to those of daunorubicin. PLD provides a longer circulation time and a higher drug concentration in tumors than in normal tissue that could lead to reduced side effects in particular life-threatening cardiotoxicity and neutropenia with infectious complications. Material and methods: Eligible patients had histologically confirmed Mycosis Fungoides stage IIb, IVa, or IVb, WHO performance status (PS) 0–2, no systemic treatment with steroids and refractory or recurrent disease after at least 2 or more previous therapies. Caelyx 20 mg/m2 was administered on days 1 and 15 in a 28-day cycle for a maximum of 6 cycles. The primary endpoint was response rate (RR), defined as patients achieved either complete clinical response (CCR) or partial response (PR). Using the Fleming design with α= 0.1 and β= 0.05 and aiming at a RR = 45% and powered to rule out a RR < 25%, 48 patients who are eligible and started treatment are required. To declare success, a 1-sided 90% confidence interval (CI) for RR should exclude 25% (the rate used in the null hypothesis). Results: Between November 22, 2003 and July 3, 2009, 9 centers registered 49 patients. All of them were eligible and started treatment. The majority of patients were male (67%), had PS 0, 1 (43%, 53%) and were between 56–65 and 66–75 year old (33% and 31%). The median (range) number of chemotherapy cycles received was 5(1-6) and the majority of patients had relative dose intensity of 90–110% and 70–90% (53% and 35%). Eighty eight percents of patients received prophylactic antiemetics; 84% had PS 0–1 during treatment. There was no Grade 3–4 hematological toxicity; only grade 2 neutropenia (4%), leukopenia (4%) and anemia (4%) were observed during treatment. Grade 3/4 non-hematologic/non biochemical toxicities were cardiac (2%), allergy (2%), constitutional symptom (4%), hand foot reaction (2%), other dermatologic toxicity (6%), other gastro intestinal toxicity (4%) and other infection (4%). One patient (2%) had grade 4 cardiac ischemia. Of 49 patients who were eligible and started treatment, 20 (40.8%) were responders: 3 (6.1%) CCR and 17 (34.7%). The 1-sided 90% CI for the RR is: (31.2%, 100%). Conclusion: The primary RR endpoint of the study was reached (ie, 1-sided 90% CI excludes 25%). We conclude that Caelyx™ should be considered for further investigation. Caelyx™ has an acceptable safety profile with only a few toxicities and no sepsis observed in this patient population of advanced age. Its efficacy appears promising.

Abstract Background: Ruxolitinib (RUX), a JAK1/JAK2 inhibitor, and venetoclax (VEN), a BCL-2 inhibitor are 2 drug candidates recently identified as promising candidate for the treatment of T-Cell prolymphocytic leukemia (T-PLL). We recently reported that JAK/STAT pathway inhibition with RUX enhances BCL-2 dependence, thereby sensitizing T-PLL cells to VEN (Herbaux et al., Blood, 2021). We also showed that JAK/STAT pathway mutational status could impact RUX activity. Here, we report results on the 15 first patients who were treated with RUX and VEN oral combination for T-PLL. All patients were refractory to, or ineligible for alemtuzumab, the principal therapeutic option to date. Methods: In this multicenter retrospective study from the French Innovative Leukemia Organization, 15 patients with T-PLL (according to consensus criteria) were included. All patients were informed about the off-label use of this combination and provided informed consent. Patients received a maximum dose of RUX 15 mg twice daily, and VEN 800 mg daily. VEN was started with daily ramp-up from 20 mg to 800 mg over 6 days, with TLS prophylaxis (rasburicase and IV hydration). Responses were assessed by consensus criteria. Next generation sequencing (NGS) was performed using a custom-designed panel of 33 genes, including among others: ATM, TP53, IL2R, JAK1, JAK3, and STAT5B. CytoScan HD microarray (Affymetrix) were used to study copy number variation and or uniparental disomy. In vivo dynamic BH3 profiling (DBP) was performed on samples obtained from two patients on treatment. Results: All 15 patients were refractory or relapsing after chemotherapy (mostly bendamustine and pentostatin), except one. They were either refractory to (n=10) or ineligible (n=5) for alemtuzumab (ineligibility was decided by the treating physician based on age and comorbidities). The median age was 70 years (48-88). Within a week of starting RUX, a transient increase of the absolute lymphocyte count was observed in 66.6% of the patients. Based on the molecular status of the JAK/STAT pathway, we established 2 groups of patients. One with samples where no mutations were found (WT, n=3), and one with at least one mutation in the JAK/STAT pathway (MUT, n=12). The overall response rate (ORR) was 73.3%, with only partial responses. Five patients nearly fulfilled CR criteria except that they had persistent lymphocytosis (over 4 x 10 9/L), all of them were in the MUT group. ORR was 83.3% in the MUT group, and only one patient of the WT group obtained a PR. With a median follow-up of 73 days (22 to 368), the median progression free survival was significantly shorter in the WT group in comparison to the MUT group (1.8 months versus 5.6 months, p=0.04, Figure). Of note, four patients were treated with VEN monotherapy before the start of the combination with RUX. With that treatment, 3 of these patients achieved stable disease followed by progression within 2 to 3 months, while 1 was primary refractory to VEN monotherapy. The most frequent reported adverse events (AEs) of the RUX plus VEN combination were cytopenias, with 46.6% grade 3 or 4 thrombocytopenia and 40% grade 3 or 4 neutropenia. DBP showed that overall priming and BCL2 dependence increased in vivo (n=2) during the treatment with RUX and VEN. Finally, SNP arrays identified clonal evolution in the 3 patients evaluated sequentially (before treatment versus at progression). In one case, emergence of EZH2 and JAK1 mutation was also observed at progression using NGS. Conclusions: These preliminary results suggest promising activity of RUX plus VEN in T-PLL, and justify the development of a prospective clinical trial of this combination. Our data seem to show that this combination may be especially active for patients with JAK/STAT pathway activating mutations and that disease progression is associated with clonal evolution. Updated results will be presented at the meeting. Figure 1 Figure 1.

Background: Fever is a cardinal symptom of cytokine release syndrome (CRS) after CAR T-cell therapy with 84% of patients experiencing fever on the ZUMA-1 trial of axicabtagene ciloleucel (axi-cel). Knowledge of the patterns of fever and associated symptoms may inform the clinical management of these patients. Methods: We performed a single center retrospective study in 78 patients receiving axi-cel for large B cell lymphoma (LBCL) as of 12/31/2018. We evaluated all the patients who developed fever during lymphodepleting chemotherapy with fludarabine (Flu) and cyclophosphamide (Cy), after CAR T-cell infusion, and after administration of tocilizumab (toci); and analyzed the association of fever with toxicity rates (grade 3+ CRS and neurotoxicity) and efficacy [overall response rates (ORR) and complete response (CR) rate 6 months post CAR T-cell infusion]. Fever was defined per the Lee criteria [equal to or greater than 38 °C], CRS used the modified Lee criteria and neurotoxicity used the CARTOX grading system. Results: Fever occurred in 71/78 (91%) of patients. Rates of grade 3+ CRS and neurotoxicity were 9% (7/78) and 26% (20/78) respectively. The CR rate at 6 months was 41% (32/78). Toxicities and outcomes in patients with the described fever characteristics are shown in the Table. During lymphodepletion with Flu/Cy, fever was observed in 11% (9/78) of patients. Fever occurred within 24 hours of axi-cel infusion in 47% (37/78) and within 72 hours of axi-cel infusion in 71% (55/78) of the patients. In total, 41% (32/78) of patients were treated with anti-IL6R therapy (tocilizumab; toci) for CAR T toxicity. After the first dose of toci, fever recurred in 69% of patients (22/32), of which 34% (11/32) experienced fever recurrence within 24 hours of toci infusion. Conclusions: This is the first study to our knowledge that describes in detail the characteristics of fever after CAR T-cell therapy with axi-cel. Fever was common and occurred in 71% of the patients within 72 hours of axi-cel infusion. When toci was used, fever recurred in a majority of patients (69%) and in 1/3 of patients the fever recurred within 24 hours of toci infusion. These descriptive data may be used by clinicians to inform their expectations of fever occurring after treatment with axi-cel and/or toci. Table Disclosures Bachmeier: Kite/Gilead: Speakers Bureau.

Abstract Introduction: Chimeric antigen receptor (CAR) T-cell therapy is a novel adoptive immunotherapy utilizing autologous T cells expressing synthetic fusion proteins that target specific antitumor antigens. Over recent years, novel CAR T-cell constructs have shown efficacy for the treatment of hematologic malignancies. The B-cell maturation antigen (BCMA)-directed CAR T-cell product idecabtagene vicleucel (ide-cel) is the first approved CAR T-cell therapy for the treatment of multiple myeloma (MM). While ide-cel represents an important advance in MM treatment, it is critical to better characterize the risk of infectious diseases following this novel therapy. Methods: We investigated infectious complications in 27 (CRB-401, n/62; KarMMa, n/128) adult patients who received ide-cel for relapsed and refractory MM at two institutions. Patients were enrolled in an open label, multi-site Phase 1 or 2 clinical trial (NCT02658929; NCT03361748) evaluating the safety and efficacy of ide-cel. All participants received a 3-day cycle of lymphodepleting chemotherapy with fludarabine and cyclophosphamide 5 days prior to infusion and ide-cel was administered at target doses of 150×10 6 to 450×10 6 CAR-positive T cells. All patients but one received antiviral prophylaxis with val/acyclovir or famciclovir. Seventeen patients received pneumocystis prophylaxis with atovaquone or trimethoprim-sulfamethoxazole. Only 2 patients received antibacterial prophylaxis with levofloxacin and no patients received antifungal prophylaxis. Infections were retrospectively identified from day of cell infusion (day 0) up to day 100 after infusion. Infections were reported if patients experienced symptoms with a microbiologic or histopathologic diagnosis, or for symptomatic site-specific infections in conjunction with radiographic or exam findings and treatment with systemic antimicrobials. Infection severity was determined using the Blood and Marrow Transplant Clinical Trials Network criteria. Cytokine release syndrome (CRS) events were graded according to the Lee criteria. Patients were censored on date of disease relapse, the last day of the study period, or death. Results: Median age was 59 (range 41 - 79), 56% were males. Patients had received a median of 6 previous antimyeloma regimens (range 3 - 10); and 74% had undergone prior autologous hematopoietic cell transplantation. Following infusion of cells, 24 patients (89%) developed CRS with 54% of those receiving ≥ 1 dose of tocilizumab and 17% receiving ≥ 1 dose of corticosteroid. Only two patients (7%) developed CAR T cell associated neurotoxicity (ICANS) and one of those patients received treatment with corticosteroids. Eight patients experienced 19 infection-related events over the first 100 days after ide-cel infusion. To determine infection density, we evaluated 27 patients contributing 667 days at risk between d0 and d30 and 1777 days at risk between d0 and d100. Median time to first infection was 22 days (range 0 - 85). The estimated infection density was 1.8 infections per 100 patient days over the first 30 days, and decreased to 1.1 infections per 100 patient days from day 30 to d100. Among the infection events, bacterial infections were the most common (74%) with 6 bloodstream infections (32%) observed. Viral infections were less frequent (21% of events) and only one fungal infection (5% of events) was observed during the at-risk period. Four infections were of moderate severity; 10 were severe; and 5 were life-threatening. Eleven of the 27 patients (41%) had persistent neutropenia (absolute neutrophil count <1000) after day 30. Conclusions: Our study in this cohort of patients provides clarity on specific infectious complications in a unique population, and is of particular relevance given the recent FDA approval of ide-cel. Of note, these results represent a cross study single institution subgroup analysis that may not reflect the complete trial data. The overall incidence of infection was similar to what has previously been reported in patients receiving CD-19 directed CAR T-cell therapy, even with persistent neutropenia after one month documented in 41% of patients. Bacterial infections were the most common, and there were 5 life-threatening bacterial infections within the first 30 days after infusion. Notably, patients in this group experienced only 1 fungal infection, despite no patients receiving antifungal prophylaxis. Figure 1 Figure 1. Disclosures Sperling: Adaptive: Consultancy.

Abstract Abstract 206 Lenalidomide is an immunomodulatory agent that has clinical activity in CLL. In patients (pts) with relapsed/refractory CLL treatment with single agent lenalidomide induces an overall response rate of 32–47% when used as monotherapy (Chanan-Khan A.A. et al. 2006; Ferrajoli A. et al. 2008). Rituximab has modest activity as monotherapy, but significally synergizes with chemotherapy agents when administered to pts with CLL. The addition of rituximab to lenalidomide resulted in clinical responses in a small number of pts with CLL that had progressed while on lenalidomide monotherapy (Chanan-Khan A.A. et al. 2006). Because lenalidomide stimulates NK cell proliferation (Wu et al. 2008) we hypothesized that lenalidomide will enhance the activity of rituximab. We, therefore, designed a phase II study to evaluate the combination of lenalidomide and rituximab in pts with relapsed CLL. Pts with CLL and active disease were eligible if they had received prior treatment with purine analog-based therapy. Standard inclusion criteria were required in terms of organ function and performance status, and pts with any ANC or platelet count were eligible. All pts received rituximab (375 mg/m2) intravenously on days 1, 8, 15 and 22 of cycle 1, and then once every 4 weeks during cycles 3–12. Lenalidomide was given orally at the dose of 10 mg/day starting on day 9 of cycle 1 and continued daily for 12 cycles. Each cycle consisted of 28 days of treatment. During the first two weeks of therapy, allopurinol at the dose of 300 mg daily was prescribed as prophylaxis for tumor lysis. Sixty pts were accrued between October 2008 and July 2009. Thirty-seven pts have received treatment for at least 6 cycles and are evaluable for response and toxicity. The median age is 59 yrs (range 44–83), 15 pts (41%) have Rai stage III-IV disease and the median beta-2M level was 3.6 mg/dL (1.5–9). The median number of prior treatments was 2 (1–9), 9 pts (24%) were refractory to fludarabine and all pts had received prior rituximab. Twenty-six pts (70%) had unmutated IgVH, 9 pts (24%) had chromosome 17p deletion and 10 pts (37%) had 11q deletion by FISH analysis. After 6 cycles of treatment, 25 pts achieved a response [6 nodular PR (16%), 19 PR (51%)] for an OR of 68% (according to 1996 NCI-WG criteria). Six pts (16%) attained stable disease or clinical improvement and are continuing on treatment, and 6 pts (16%) failed to respond, including one death that occurred on day 34 owing to infectious complications. Responses according to pts characteristics are summarized in the table: Most common grade 3–4 treatment related adverse events observed were: neutropenia (16 pts, 43%), fatigue (6 pts,16%) and thrombocytopenia (4 pts, 11%). One pt (3%) developed grade 3 tumor lysis syndrome and 1 pt (3%) had grade 3 joint pain. Infectious complications occurred in 9 pts (24%): neutropenic fever (6 pts), pneumonia (2 pts) and urosepsis (1 pt). Lenalidomide-associated tumor flare reaction was limited to grade 1 (8 pts, 22%) and grade 2 (1 pt, 3%). We examined the effect of therapy with lenalidomide and rituximab on the distribution of circulating B, T, and NK cell subsets. When compared to the baseline, there were significant decreases in the percentage of CD19+CD20+ B cells along with significant increases in the percentages of CD4+ T, CD8+ T, CD4+CD25hiCD127− regulatory T, and CD3−CD16+CD56+ NK cells after 3 cycles of therapy (paired sample t test). In conclusion, our results suggest that the combination of lenalidomide and rituximab is superior to single agent lenalidomide, despite all our pts having received prior rituximab. Additionally, there was no increase in toxicity and lenalidomide-associate tumor flare reaction was less frequent and less severe with this combination compared to single agent lenalidomide.

Abstract Abstract 2737 Introduction: ATL is prevalent in Japan and has the worst prognosis among T-cell malignancies. PTCL also has a poor prognosis with currently available chemotherapeutic regimens, and both would benefit from better treatment modality. Lenalidomide is an immunomodulatory agent with direct tumoricidal and antiproliferative activity, and is approved for multiple myeloma (MM) in combination with dexamethasone after at least 1 prior therapy and for transfusion-dependent anemia due to low- or intermediate-1-risk myelodysplastic syndromes associated with 5q deletion. We conducted a phase 1 study of lenalidomide in patients with relapsed ATL or PTCL to establish the recommended dose and schedule for a subsequent phase 2 study. Patients and Methods: This multicenter, phase 1, dose-escalation study assessed the safety, maximum tolerated dose (MTD), pharmacokinetics, and efficacy in patients with relapsed advanced ATL or PTCL. Dose-escalation was conducted according to the standard 3+3 design. Up to one PTCL patient was allowed to be included in each cohort of 3 patients. Patients in Cohort 1 received oral lenalidomide 25 mg daily on Days 1–21 of a 28-day cycle. Patients in Cohorts 2 and 3 received 25 and 35 mg/day, respectively, on each day of the 28-day cycle. Dose-limiting toxicity (DLT) was defined as febrile neutropenia lasting 5 or more days; thrombocytopenia (platelets <10,000/uL or bleeding requiring platelet transfusion); ALT/AST elevation of Grade 4 or that of Grade 3 lasting 7 or more days; and/or clinically unacceptable Grade 3 or higher other non-hematological adverse events (AEs). Treatment was continued until the development of unacceptable toxicity or progressive disease (PD). Response was assessed by internationally accepted standard criteria for ATL and PTCL. Results: From July 2010–June 2012, 13 Japanese patients (9 ATL and 4 PTCL; age 32–74 years [median, 64]; 1–11 prior therapies [median, 1]) were enrolled: 3 in Cohort 1, 6 in Cohort 2, and 4 in Cohort 3. The 3 patients in Cohort 1 received lenalidomide for 21, 103, and 637 days, respectively, until PD with no instances of DLT. In Cohort 2, 1 patient experienced DLT (thrombocytopenia, platelets <10,000/uL) and 4 patients received lenalidomide for 37, 56, 138, and 387 days, respectively, until PD in 3 patients and unrelated death in one. The sixth patient is still receiving lenalidomide for 28+ days without a DLT. In Cohort 3, 2 patients had DLTs (thrombocytopenia, platelets <10,000/uL in one patient and Grade 3 prolongation of QTc interval in one patient on concomitant fluconazole with preexisting cardiac disease and grade 1 QTc prolongation at baseline), 1 patient received lenalidomide for 71 days before withdrawal of consent, and 1 patient is still receiving lenalidomide for 323+ days without a DLT. Based on these results, 25 mg daily per 28-day cycle was regarded as the MTD. Other Grade 3/4 non-DLT AEs occurring in 2 or more patients included neutropenia (n=8), lymphocytopenia (n=7), thrombocytopenia (n=3), skin rash (n=3), hyperbilirubinemia (n=2), and increased ALT/AST (n=2). Among the 9 ATL patients, 3 achieved partial responses (PR) with hematological complete response in 2 patients, including the disappearance of skin lesions in 1 patient. These responses occurred between 54 and 57 days, and lasted for 92, 279+ and 505 days. Among the 4 PTCL patients, 1 achieved a PR at day 106 with >75% reduction in lymph nodes, which lasted for 282 days. PK profiles of patients in the study were generally consistent with that observed in Japanese MM patients. Plasma exposure of lenalidomide increased with increasing dose with a mean Cmax on Day 1 for 25 mg and 35 mg of 493 ng/mL and 628 ng/mL, respectively, and a mean AUC24 of 2774 ng/mL and 3062 ng/mL, respectively. There was no evidence of accumulation following multiple dosing for 8 days. Conclusions: This phase 1 study identified lenalidomide 25 mg daily per 28-day cycle as the dose and schedule for a subsequent phase 2 study in patients with ATL or PTCL. Based on the preliminary evidence of antitumor activity in ATL and PTCL patients, a phase 2 study in patients with relapsed ATL in Japan is planned.

Abstract Background:Epigenetic manipulation and immunomodulation are therapeutic strategies in hematologic malignancies. In our previous study, the combination of romidepsin and lenalidomide demonstrated a 58% overall response rate, complete response rate of 11% and median event free survival was 16 weeks in patients (pts) with relapsed or refractory T-cell lymphoma. Given the potential synergy of proteasome inhibitors with histone deacetylase inhibitors and lenalidomide, we conducted a phase Ib/IIa study to evaluate the safety and toxicity of romidepsin and lenalidomide in combination with carfilzomib in pts with relapsed or refractory lymphoma. Here we report the safety, toxicity, and maximum tolerated dose (MTD) from the completed phase I portion of the study as well as the efficacy data from the completed T-cell lymphoma phase IIa cohort. Methods: The phase I portion evaluated toxicity and defined MTD. The clinicalactivity of the combination of romidepsin, lenalidomide, and carfilzomib was assessed in the phase I and lineage specific phase IIa cohorts. Romidepsin and carfilzomib were given IV on days 1, 8 and lenalidomide was given orally on days 1-14 of a 21-day cycle. A standard 3+3 dose escalation schema was followed: The starting dose was romidepsin 8 mg/m2,lenalidomide 15 mg, carfilzomib 36mg/m2. Dose-limiting toxicity (DLT) was defined in cycle 1 as ≥ grade 3 non-hematologic toxicity, grade 4 hematologic toxicity, grade ≥ 3 thrombocytopenia with bleeding, grade 3 hematologic toxicity resulting in a significant delay of treatment or inability to receive day 1 of cycle 2 due to continued drug related toxicity. Tumor response was based on disease-specific criteria.Pts could be treated until progression, intolerance, or response adequate to allow allogeneic transplantation. Results:20 pts were enrolled with 19 evaluable for toxicity (1 patient with T-cell lymphoma progressed prior to receipt of any study drug). 17 pts were treated for T-cell lymphoma (11 in the phase 1 portion and 6 in the phase IIa cohort): peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS)-9, angioimmunoblastic T-cell lymphoma (AITL)-4 (one with concurrent diffuse large B-cell lymphoma-DLBCL), mycosis fungoides (MF)-2, transformed MF-1, extra-nodal NK/T-cell lymphoma (ENKTCL)-1. 3 pts in the phase 1 portion were treated for B-cell lymphoma: DLBCL-3. The T-cell lymphoma cohort is complete and efficacy data is reported here. Dose level 2 (romidepsin 8 mg/m2,lenalidomide 15 mg, carfilzomib 45mg/m2) exceeded the MTD with 2/6 DLTs: 1 pt with grade 3 thrombocytopenia resulting in treatment delay and 1 pt with grade 4 thrombocytopenia. There were no DLTs among 6 pts treated in dose level 1 (romidepsin 8 mg/m2,lenalidomide 15 mg, carfilzomib 36mg/m2) and dose level 1 was deemed the MTD. Grade 3-4 toxicities in >10% pts included neutropenia and thrombocytopenia. SAEs included: infection-3, progression of disease resulting in hospitalization-3, fever-2, febrile neutropenia-1, DVT-1, edema-1, dyspnea-1, atrial flutter-1, generalized weakness-1, and vomiting with diarrhea-1. Of the 16 pts with T-cell lymphoma evaluable for response, the overall response rate was 50% (8/16, 95% CI: 25 to 75%). The complete responses rate was 31% (5/16, 95% CI: 11 to 59%) and the partial response rate was 19% (3/16, 95% CI: 4 to 46%). Complete responses were seen in AITL (4/5) and PTCL-NOS (1/8) with 3 pts in CR proceeding to allogeneic stem cell transplantation. Partial responses were seen in PTCL-NOS-1, AITL-1, and transformed MF-1. In T-cell lymphoma, the median event free survival for all pts was 9.7 weeks (95% CI: 6.0 to NR) and for responders was not reached (95% CI: 15.0 to NR). The median time to response was 5.8 weeks. The median duration of response was 9.6 weeks (95% CI: 8.0 to NR). 3 pts underwent allogeneic transplantation following this therapy and another 2 pts with CR remain in continuous remission. Median duration of follow up was 20.4 weeks (range 3.4-40.9 weeks). Conclusions: The MTD dose for phase 2 study was identified as romidepsin 8mg/m2, lenalidomide 15mg and carfilzomib 36mg/m2. No unexpected toxicities have emerged. The preliminary overall and complete response rates of this regimen are promising in T-cell lymphoma, particularly in AITL, and warrants further study. An expansion cohort in B-cell lymphoma cohort is ongoing. Disclosures Moskowitz: Seattle Genetics: Consultancy, Research Funding; BMS: Consultancy.

Abstract Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of lymphomas in which only ~25% of patients experience long-term survival with CHOP chemotherapy. Recently several drugs have been approved for this entity including pralatrexate (P), romidepsin (R), and belinostat which have response rates ranging from 26%-29% as single agents. Based on our demonstration of synergy of P+R in preclinical models of TCL, we initiated a study on the safety and efficacy of P+R in a phase I-II study for relapsed or refractory lymphomas (NCT01947140) and sought to evaluate biological mechanisms of synergy. A 3+3 dose-escalation study started at P 10mg/m2 and R 12mg/m2 with escalation to P 25 mg/m2 and R 14 mg/m2. Patients were treated on 1 of 3 dosing schedules (weekly x 3 Q28D; weekly x 2 Q21D and QOW Q28D). The primary objective was to determine MTD and DLT; the secondary objective included describing ORR (CR+PR). Patients were required to have relapsed lymphoma of any subtype, ECOG PS ≤2, and adequate organ and marrow function. There was no upper limit to the number of prior therapies or transplantation. Twenty-six patients were enrolled and were evaluable for toxicity. Median age was 52 yrs (23-73) and 58% were male. The median number of prior therapies was 3 (range 1-16). Histologies included HL (N=3), B-cell (N=10 of which FL=4) and T-cell (N=13). The median number of cycles completed was 4 (range 1-12). There were 3 DLTs in cohort 4 (P 20mg/m2 & R 12mg/m2given weekly x 2 Q21D) consisting of 2 Grade 3 oral mucositis and 1 Grade 4 sepsis. The QOW Q28D schedule had no mucositis at all dose levels. Patients dosed at the MTD (P 25 mg/m2 & R 12mg/m2 QOW) did not experience any toxicities. The grade 3/4 toxicities reported in >5% of patients were: neutropenia (31%), thrombocytopenia (31%), anemia (23%), oral mucositis (15%), hyponatremia (8%), pneumonia (8%) and sepsis (8%). Twenty-two patients were evaluable for response, 1 patient is currently on therapy. The ORR in the total, non-PTCL and PTCL populations was 59%; 33% (no CR) and 77% respectively. Of the PTCL patients 4/13 (31%) achieved a CR, 6/13 (46%) achieved a PR, and 1 patient had stable disease. The mean duration of response (DOR) for all patients on the study (N=13) was 6.1 months (1.1 - 26.5), for the non-PTCL population (N=3) was 4.8 m (1.1-11) and for the PTCL population (N=10) was 6.55 months (range 1.6 - 26.5 +ongoing). The mean progression free survival (PFS) for all patients on study (N=26) was 4.8 m (.3 - 30.2), for the non-PTCL population (N=13) was 2.8 m (0.3-14.5), and for the PTCL population was 6.13 months (range 1.5 - 30.2 +ongoing). Pharmacokinetic studies were performed for P and R and data for the first 15 patients is presently available for reporting. PK analyses were performed using WinNonLin® to determine Cmax and AUC. Preliminary Cmax results for P 10 mg/m2 and P 15 mg/m2 are 1810+/-1063 ng/mL and 2748+/-995 ng/mL, respectively. Preliminary Cmax results for R 12 mg/m2 and R 14 mg/m2 are 420+/-198 ng/mL and 552+/- 346 ng/mL, respectively. After infusion with P 10 mg/m2 or 15 mg/m2 PK analysis indicate AUC0-24.08h of 3616+/-1543 h*ng/mL and 4104+/-2124 h*ng/mL, respectively. AUC0-28h after treatment with R 12 mg/m2or 14 mg/m2 was 1503+/-1286 h*ng/ml and 2535+/-2560 h*ng/mL. These values are consistent with that observed for both of these drugs in previous studies. Results from the phase I study conclude that the combination of P + R given on the QOW schedule is safe and very well tolerated. These data support the lineage specific activity of the P+R combination, which is currently being expanded to a multicenter Phase II for PTCL. Figure Figure.

Background: Patients (pts) with R/R aggressive large B cell NHL who fail first-line therapy with immunochemotherapy and are ineligible for high-dose chemotherapy and hematopoietic stem cell transplantation (HSCT) have a poor prognosis. Available treatment options include platinum/gemcitabine-based or bendamustine-based regimens in combination with rituximab, with or without radiotherapy, or clinical trials. However, long-term outcomes remain poor due to lack of a curative option. Liso-cel is an investigational, anti-CD19, defined composition, 4-1BB CAR T cell product administered at target doses of CD4+ and CD8+ CAR T cells. In the ongoing TRANSCEND NHL 001 study of liso-cel as third- or later-line treatment for pts with R/R large B cell NHL, preliminary data showed high overall response rates with a low incidence of grade ≥3 cytokine release syndrome (CRS) and neurological events (NEs) (Abramson et al, ASCO 2018). The open-label, phase 2 PILOT study is assessing the safety and efficacy of liso-cel as second-line therapy in TNE pts (NCT03483103). PILOT is the first study evaluating CAR T cell therapy focusing on this pt population. Methods: Eligible pts had R/R large B cell NHL (diffuse large B cell lymphoma [DLBCL], not otherwise specified [NOS], de novo or transformed indolent NHL, high-grade lymphoma with MYC and BCL2 and/or BCL6 [double/triple-hit lymphoma], or follicular lymphoma (FL) grade 3B) and had received only 1 prior line of immunochemotherapy containing an anthracycline and a CD20-targeted agent (eg, R-CHOP). Pts had to be deemed ineligible for high-dose chemotherapy followed by HSCT by meeting at least 1 of the following TNE criteria while still fulfilling the criteria for CAR T cell therapy: age ≥70 years, ECOG PS of 2, and/or impaired pulmonary (DLCO ≤60% but SaO2 ≥92% on room air and CTCAE ≤1 dyspnea), cardiac (LVEF ≥40% and <50%), renal (creatinine clearance >30 and <60 mL/min), or hepatic function (AST/ALT >2 and ≤5 ×ULN). Liso-cel was administered at a target dose of 100×106 CAR+ T cells after lymphodepletion (LD) with fludarabine/cyclophosphamide for 3 days. Pts could be treated as outpatients at the investigator's discretion. Results: At data cutoff, 10 pts had been leukapheresed, and 9 pts had LD followed by liso-cel infusion; 1 pt is awaiting liso-cel treatment. Liso-cel was manufactured successfully in all pts. Five pts were infused and monitored as outpatients. Median age was 71 (range, 64-79) years; 5 pts were male. Histology included DLBCL NOS (n=7) and transformed FL (n=2); 2 pts had triple-hit, one of whom had transformed from FL. Five pts had relapsed from, and 4 pts had disease refractory to, prior therapy. Median SPD and LDH were 26.6 cm2 and 201 U/L, respectively. Four pts had high tumor burden with SPD ≥50 cm2 (n=4) and/or LDH ≥500 U/L (n=1). The median Hematopoietic Cell Transplantation Comorbidity Index (HCT-CI) score was 3 (range, 0-3). Six pts had 1 or more treatment-emergent adverse events (TEAEs) grade ≥3, which were primarily cytopenias. Three pts had prolonged grade ≥3 cytopenias at Day 29. Two pts had infections of any grade; no pts had grade ≥3 infections. No pts had CRS or NEs, and no pts received tocilizumab, corticosteroids, or vasopressors. There were no cases of macrophage activation syndrome, tumor lysis syndrome, infusion reactions, or grade 5 TEAEs. Among the 5 pts treated and monitored as outpatients, none were admitted to hospital for adverse events within the first 29 days post liso-cel infusion. All 9 pts achieved an objective response. Four pts achieved complete response; all are ongoing. Five pts achieved partial response (PR), with 2 PRs ongoing. Results were similar in inpatient vs outpatient pts. Median follow-up was 3.5 months. Median (range) time to peak CAR T cell expansion was 10 (7-21) days. Conclusions: These preliminary safety and efficacy data from the ongoing phase 2 PILOT study suggest that liso-cel can be successfully administered, including in the outpatient setting, as second-line therapy in pts with R/R aggressive B cell NHL who were ineligible for high-dose chemotherapy and HSCT by prespecified criteria. Updated safety and efficacy data with longer follow-up will be presented. Disclosures Sehgal: Kite/Gilead: Research Funding; Merck: Research Funding; Juno/Celgene: Research Funding.

Abstract Introduction: Autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy achieves rapid and durable responses in patients with r/r DLBCL, although unique potential toxicities require specialized management. Cytokine release syndrome (CRS) is the most commonly observed adverse event of special interest associated with CAR T-cell therapy. Two CRS grading scales have been used in different clinical trials of CAR T-cell therapy: the Penn scale (Porter, Sci Transl Med, 2015; Porter, J Hematol & Oncol, 2018) and the Lee scale (Lee, Blood, 2014; Neelapu, Nat Rev Clin Oncol, 2017). To better inform management of CRS and develop best practices, we assessed concordance and differences between the two scales by using the Lee scale to regrade observed CRS events in r/r DLBCL patients treated with tisagenlecleucel, who were previously graded per protocol using the Penn scale. Methods: Individual patient level data from the JULIET trial, a single-arm, open-label, multicenter, global phase 2 trial of tisagenlecleucel in adult patients with r/r DLBCL (NCT02445248), were used in this study. Four medical experts who had managed DLBCL patients using different CAR T-cell therapy protocols and products independently reviewed the data, while blinded to the original Penn grading, and re-graded CRS for JULIET patients using the Lee scale. Re-grading assessments and disagreements in the assigned Lee grade were discussed and reconciled among reviewers during a live meeting. As per the investigational charter, the most conservative final assessment of any expert reviewer determined the final grading for any individual case. For example, if an event was graded as 2, 3, 3 and 4, then grade 4 would be the final grading. Results: As of December. 8, 2017, 111 patients with r/r DLBCL were infused with tisagenlecleucel in the JULIET trial. Sixty-four (58%) patients had CRS graded according to the Penn scale and each case was re-graded using the Lee scale based on JULIET data collected prospectively (e.g., CRS-related symptoms, oxygen supplementation, intervention for hypotension, and organ toxicities). Using the Lee scale, 63 (57%) patients were considered to have any grade CRS by investigators, including grade 1 events in 26 (23%), grade 2 in 18 (16%), grade 3 in 10 (9%), and grade 4 in 9 (8%) (Figure 1). One patient with grade 1 per Penn scale was re-graded to grade 0 due to absence of documented fever or symptoms requiring intervention. Compared to Penn grades, the Lee scale provided the same grade for 39 patients, a lower grade for 20 patients, and a higher grade for 5 patients. Among 64 patients re-graded, 59 (92%) had fever, 27 (42%) had oxygen supplementation (3 with grade 1, 6 grade 2, 9 grade 3, and 9 grade 4 per Lee scale) and 7 (11%) had concurrent infections. Of 29 (45%) patients requiring intervention for hypotension (13 with grade 2, 7 grade 3, and 9 grade 4 per Lee scale), 28 had fluid resuscitation and 10 received high dose/combination vasopressors. In addition, 8 of 9 patients re-graded as Lee grade 4 were intubated. As for anti-cytokine therapy, only 17 patients received tocilizumab (1 for grade 1, 2 for grade 2, 5 for grade 3, and 9 for grade 4 CRS per Lee scale) and 12 patients received corticosteroids (2 for grade 2, 1 for grade 3, and 9 for grade 4 CRS per Lee scale). Conclusions: Different CAR-T studies in DLBCL patients have used different approaches (Lee and Penn scales) for grading CRS and had different thresholds for tocilizumab treatment of CRS. Harmonization of grading CRS between studies permits a more accurate comparison of observations and outcomes. In this analysis, patients with r/r DLBCL receiving tisagenlecleucel in the JULIET trial, which used the Penn scale to grade CRS, were re-graded by expert consensus using the Lee scale. Using the Lee scale, more patients were categorized as grade 1 (Lee vs. Penn: 26 vs. 17), fewer patients as grades 2 and 3 (18 vs. 23, and 10 vs. 15, respectively), and the same number of patients as grade 4 (9 vs. 9) compared to the Penn scale. The re-grading of the JULIET CRS data using the Lee scale makes it possible to perform comparative analyses of CRS outcomes from clinical trials using different CAR-T products and could be used to develop best practice guidelines.

Abstract Introduction: T-cell prolymphocytic leukemia (T-PLL) is a very rare & aggressive disease. Therapeutic advances during recent years have been very limited. Even after initial response, the vast majority of T-PLL patients (pts) relapse quickly and the median overall survival remains below 2 years (ys). This also holds true for induction therapies with the anti-CD52 antibody Alemtuzumab (A). Furthermore, life-threatening viral infections are a severe problem in pts treated with this antibody. In a precursor trial (Hopfinger et al, Cancer 2013), we evaluated a consolidation therapy with A after polychemotherapy induction. In the T-PLL2 trial, we evaluated feasibility, safety and efficacy of the addition of A s.c. to an induction treatment with Fludarabine, Mitoxantrone & Cyclophosphamide (A-FMC), followed by an A s.c. maintenance therapy. Patients and Methods: 16 pts (12 untreated and 4 with pretreatments) with T-PLL were enrolled between 06/2010-09/2013. Pts received an induction treatment with A 10mg s.c. on day (d) 1-3 combined with 20mg/m2 Fludarabine i.v. d 1-3, 6mg/m2 Mitoxantrone i.v. d1 & 200mg/m2 Cyclophosphamide d1-3. After 2 cycles the A dose was increased to 30 mg s.c., if a stable disease (SD) or a partial remission (PR) was achieved. A-FMC treatment was administered every 28 days for up to 4 cycles, followed by a maintenance treatment with 30mg A s.c. starting 1 month (mo) after final staging. During the first 6 mo, A s.c. was administered monthly and in addition once in mo 10 and 13. For younger and fit pts, the option of allogeneic transplantation (tx) was explicitly recommended after induction therapy. Peripheral blood (PB) samples were taken at diagnosis & at the time of relapse/progression. Valganciclovir was recommended for prophylaxis. Results: 16 pts with a median age of 68 ys (range 32-78) and a median score on the cumulative illness rating scale of 3 (range 0-6) were enrolled. The diagnosis of T-PLL was established based on clinico-pathologic characteristics, with the lead finding of a monoclonal mature T-cell population in PB. All leukaemias (100%) were CD52 positive, 15/16 cases (93.75%) expressed TCL1 & the most frequent abnormalities by FISH/classical karyotyping were aberrations involving 14q32.1 in 14/14 cases (100%), gains of chromosome 8q in 10/14 cases (71%), & deletion 11q23 in 8/14 cases (57%). A median number of 4 courses (range 2-4) were administered for induction treatment. Six pts (37.5%) proceeded with maintenance treatment with a median of 4 (range 1-6) A applications. In total, 94 non-infectious CTC grade 3-4 adverse events (AE) & 28 episodes of CTC grade 1-4 infections were documented. Non-infectious grade 3/4 AEs were most frequently due to myelosuppression: neutropenia/leukopenia occurred in 14/16 pts (87.5%), anaemia in 7/16 pts (43.75%) & thrombocytopenia in 10/16 pts (62.5%). Two cases of cytomegalovirus (CMV) & 1 case of varicella zoster infection were documented. Most AEs could be successfully managed, however 2 (12.6%), possibly treatment related deaths occurred, both from fatal bleeding in thrombocytopenia. In all pts response data after induction treatment was available. The overall response rate was 68.75% (11/16pts) with complete remissions (CR) in 4 pts (25%), CR with insufficient bone marrow recovery in 1 pt (6.25%) & a PR in 6 pts (37.5%). Progressive disease (PD) was documented in 4 pts (25%), a SD in 1 pt (6.25%). The trial was terminated in May 2014. Until today, 11 deaths (68.75%) were reported & 1 pt (6.25%) was lost to follow-up. Prophylaxis with Valgancyclovir was administered in 12/16 pts (75%), 2 pts (12.5%) received prophylactic Valaciclovir & 2 pts (12.5%) received no viral prophylaxis at all. Seven pts (43.75%) received an allogeneic tx after the study treatment: 3 pts after the induction phase, 1 pt after 5 maintenance applications & 3 pts after bridging/salvage therapy. Tx outcomes were documented with 5 CRs & 2 PDs. Conclusion: A s.c. combined with FMC & A maintenance therapy is a relatively safe and feasible regimen in pts with T-PLL. However, safety seems to come at the cost of response quality. Therefore, the authors currently recommend using A i.v. as part of the initial therapy for T-PLL pts. Prophylaxis with Valganciclovir was effective in preventing CMV infection, one of the major threats to pts treated with A. Most importantly, the study emphasizes the need for new therapies and intensified clinical research for pts with T-PLL.
