Background: Cutaneous T cell lymphoma is incurable with current therapies and there is an urgent need for more effective therapies. BNZ-1 is a pegylated peptide antagonist that binds to the common γc signaling receptor for the cytokines IL-2, IL-9 and IL-15. These cytokines, particularly IL-2 and IL-15, have been implicated in the pathogenesis of CTCL through activation of JAK/Stat signaling pathways, Therefore, we hypothesized that inhibition of the IL-2 and IL-15 signaling pathways in CTCL will induce antitumor activity in patients with CTCL. Methods: A multicenter, open-label Phase 1 study is ongoing to characterize the safety and tolerability of BNZ-1 (NCT03239392). Patients with a diagnosis of mycosis fungoides (MF) of any stage or Sézary syndrome (SS) are eligible for this trial. Pts are enrolled in sequential dose cohorts of 0.5 mg/kg, 1mg/kg, 2 mg/kg, and 4 mg/kg to receive intravenous dose of BNZ-1 to characterize safety, pharmacokinetics, pharmacodynamics, and evidence of antitumor activity. Infusions are administered weekly for four doses to evaluate for safety. Thereafter, patients are enrolled on an extension phase for 3 months of weekly dosing of BNZ-1. If patient attain a response, they are eligible for a long-term extension arm, as approved by the FDA. Blood samples are collected to assess the impact of BNZ-1 on the anti-tumor response. Results: pts with MF/SS (11 M/5F, median age 61 years, range 32-89) have been enrolled. Clinical stages include IB (n=6), IIA (n=1), IIB (n=6), IVA1 (n=2), IVB (n=1). Patients were previously treated with a median of 2 ( 1-5) topical therapies and 3 (1-11) systemic therapies. Single and sequential doses of weekly 1 mg, 2 mg, or 4 mg BNZ-1 infusions have been well tolerated. The most frequently reported adverse events were pruritus (n=9), fatigue (n=5) and dry skin (n=3). All treatment-related AEs were Grade 1 or 2 in severity. No SAEs or dose limiting toxicity have been observed to date. Notably reductions in mSWATs and CAILs was noted even in patients with advanced stage disease and/or with features of large cell transformation and folliculotropic subtype. Flow cytometry of peripheral blood at baseline and during treatment indicated activation of anti-lymphoma immune responses associated with the downregulatio of PD1. Concommittantly, excess expression of cytotoxic granules (perforin & Granzyme B) has been downregulated, suggesting the silencing of inflammatory T-cell responses. Conclusions: These preliminary Phase 1 results suggest that pegylated BNZ-1 is well-tolerated and inhibition of IL-2 and IL-15 leads to clinical improvement in patients with CTCL. Evidence for the rejuvenation of anti-lymphoma immunity and a decreasing inflammatory responses was seen in cases showing clinical response consistent with our hypothesis. An expansion cohort in CTCL is currently underway to validate these promising early results.

Introduction: Tenalisib (RP6530) is a novel, highly specific, dual PI3K δ/γ inhibitor with nano-molar inhibitory potency at the enzyme and cellular level. PI3K plays a critical role in T-cell development and activation and several studies have validated the PI3K-AKT pathway as a potential therapeutic target in T cell lymphomas. Preliminary results of the ongoing Phase 1/1b T-cell lymphoma (TCL) study demonstrated an acceptable safety profile with encouraging clinical activity in relapsed/refractory TCL (Oki, ASCO 2018 and Iyer, ASH 2018). We now present the final results of the study (NCT02567656). Methods: This study comprised of four-dose escalation cohorts, followed by two dose expansion cohorts at MTD enrolling 20 patients each in PTCL and CTCL cohorts. Patients had histologically confirmed TCL, ECOG PS ≤2, and had received ≥1 prior therapy. Patients received Tenalisib [200 mg BID-800 mg BID (fasting), 800 mg (fed only)] orally until progression or unacceptable toxicity. The primary objectives were to determine the MTD and pharmacokinetic profile. The secondary objective was to evaluate overall response rate (ORR) and duration of response. Responses were evaluated for PTCL and CTCL based on IWG criteria (Cheson 2007) and mSWAT respectively. Adverse events were graded according to CTCAE v4.03. Results: Fifty-eight patients were enrolled in study, 19 in dose escalation and 39 in dose expansion (28 PTCL and 30 CTCL). Median number of prior therapies was 4 (range, 1-15). Safety assessment of 58 patients receiving at least one dose of Tenalisib demonstrated an acceptable safety profile. Treatment related Grade≥3 AEs were elevated ALT/AST (21%), rash (5%), and hypophosphatemia (3%). These events were reversible and managed by withholding study drug. Additionally, in few patients (N=9), steroids were used to manage elevated ALT/AST. There were six treatment related serious adverse events, none of these led to fatal outcome. At end of the study, four (3 CTCL; 1 PTCL) patients who completed minimum 8 cycles of therapy were rolled over to a compassionate use study (NCT03711604) and were followed up. Efficacy assessments demonstrated an ORR of 46% (3 CR and 13 PR) and clinical benefit rate (CR+PR+SD) of 77%. Subset efficacy analysis showed an ORR in PTCL of 47% (3 CR; 4 PR) and in CTCL of 45% (9 PR). The median time to initial response was 1.8 months and was similar in both sub-types. The overall median DOR was 4.91 months (range 0.9-26.6); in PTCL patients the DOR was 6.53 months, (range: 0.97-21.0) and 3.8 months (range: 1.67-25.67) in CTCL patients. In 3 PTCL patients who achieved CR, the median DOR was 19.5 months (range 7.5-21). Conclusion: Tenalisib demonstrated promising clinical activity and an improved safety profile in patients with relapsed/ refractory TCL. Currently, a phase I/II combination study to further evaluate safety and efficacy with romidepsin is ongoing in this target population.

Prior Systemic Therapy

Abstract Abstract 114 Background: Romidepsin is a potent HDAC inhibitor approved by the FDA for patients (pts) with cutaneous T-cell lymphoma who have received at least 1 prior systemic therapy. Durable clinical benefit and tolerability of romidepsin in pts with recurrent or refractory PTCL have been previously observed in a phase 2 trial conducted by the National Cancer Institute. The aim of this phase 2, single-arm, open-label registration study was to evaluate the activity of romidepsin in a larger number of pts with progressive or relapsed PTCL. Methods: Pts with histologically confirmed PTCL (PTCL NOS, angioimmunoblastic T-cell lymphoma, ALCL [ALK-1 negative], other subtypes) who failed or were refractory to ≥ 1 prior systemic therapy, and had measurable disease and ECOG performance status 0–2 were eligible. Exclusions included inadequate bone marrow or other organ function and significant cardiovascular abnormalities. Pts received romidepsin 14 mg/m2 as a 4-h IV infusion on days 1, 8, and 15 every 28 days for up to 6 cycles; treatment could be extended for stable disease (SD) or response. The primary endpoint was rate of complete response (CR + CRu) as evaluated by a central Independent Review Committee (IRC) using International Working Criteria for non-Hodgkin's lymphoma. IRC assessment consisted of a 2-step process, with initial radiographic review of images (CT, MRI) followed by an overall clinical assessment based on the radiology evaluations, photographs, and relevant clinical parameters. Secondary endpoints included objective response rate (ORR): CR + CRu + partial response (PR), investigator-assessed responses, duration of response, time to response, and safety. Results: 131 pts from 48 US, European, and Australian sites were enrolled and received at least 1 dose of romidepsin (as-treated population); 130 patients had histologically confirmed PTCL by central review. Mean age of all pts was 59.4 y (range, 20–83) and median time since diagnosis was 1.25 y (range, 0–17). Median number of prior systemic therapies was 2 (range, 1–8). 21 pts (16%) had failed a prior stem cell transplant. Responses assessed by the IRC are noted in the table below. Longest duration of response is 26+ mo and 16 (94%) of the 17 pts with a CR had not progressed as of the data cutoff (March 31, 2010). Investigator-assessed responses included 21 pts (16%) with CR + CRu, 18 pts (14%) with PR for an ORR of 30%. Currently, 13 pts continue to receive treatment (range, 10–36 cycles). Adverse events (AEs) were reported in 126 of 131 pts (96%). AEs reported in ≥ 20% of pts were nausea (59%), fatigue (41%), vomiting (38%), thrombocytopenia (38%), diarrhea (35%), pyrexia (34%), neutropenia (30%), anorexia (28%), constipation (28%), anemia (23%), and dysgeusia (21%). AEs ≥ grade 3 were reported for 86 pts (66%), with the most common (≥ 5%) being pneumonia (5%), pyrexia (5%), sepsis (5%), and vomiting (5%). 60 pts (46%) had at least 1 serious AE: the most frequently reported (≥ 5%) were pyrexia (7%), pneumonia (5%), vomiting (5%), and sepsis (5%). 22 pts (17%) withdrew due to AEs. 8 pts (6%) died within 30 days of the last dose of romidepsin; 1 death, due to sepsis, was assessed as possibly related to treatment. Conclusions: Complete and durable responses were observed with single agent romidepsin in pts with relapsed PTCL. These data support the therapeutic potential for romidepsin in relapsed PTCL and suggest that romidepsin is a strong candidate for inclusion in future novel regimens for these diseases. As of the data cutoff (March 31, 2010), the median duration of follow-up for CR is 8.2 mo.

Abstract OBJECTIVES: To determine whether individual items on patient-reported outcome measures show significant differences over the course of treatment for patients with cutaneous T-cell lymphoma (CTCL). METHODS: A large, open-label, multi-center, randomized, Phase 3 study compared mogamulizumab, an anti-C-C chemokine receptor type 4 (CCR4)-targeted antibody, versus vorinostat in 372 CTCL patients who had failed ≥ 1 prior systemic therapy. Clinical quality of life (QoL) measurements included Skindex-29, Functional Assessment of Cancer Therapy-General (FACT-G), and two measures of pruritus (a Likert Scale and ItchyQoL). Analyses on identified individual symptom items of Skindex-29 and toxicity items of FACT-G were conducted using longitudinal generalized estimation equations (GEE) of the post-baseline, treated period assessments (through Cycles 5 or 6, depending on collection schedule) for these items. The proportion of patients experiencing a 1-grade improvement is presented in terms of frequency and percentage by treatment arm. Forest plots of odds ratios (OR) and associated confidence intervals (CI) from the GEE analyses were generated to characterize the likelihood of a 1-grade categorical improvement (eg, improvement by 1 category on the verbal response scale) on individual items for patients treated with mogamulizumab compared to vorinostat during the first 6 cycles of therapy. RESULTS: The likelihood of patients experiencing a 1-grade improvement in skin symptoms, side effect bother, and lack of energy was higher for patients treated with mogamulizumab compared to vorinostat (OR > 1.0). Patients treated with mogamulizumab were more likely to observe a 1-grade improvement in painful skin (OR=1.74, CI=1.180-2.572), irritated skin (OR=1.34, CI=0.909-1.978), lack of energy (OR=2.20, CI=1.461-3.309), side effect bother (OR=1.28, CI=0.810-2.020), and general cancer pain (OR=1.38, CI=0.922-2.063) within 6 cycles of therapy (Figure). The single item descriptive and proportion analysis of 1+ grade improvement at cycle 5 from baseline is presented (Table). CONCLUSIONS: These data provide detailed information on the cumulative probability of categorical improvement of individual items on the skin symptoms of Skindex-29 and the toxicity bother, energy, and pain items of FACT-G. These results support symptom benefit of mogamulizumab over the course of treatment compared to vorinostat. Disclosures Porcu: Innate Pharma: Consultancy. Leoni:Kyowa Kirin: Employment.

Abstract Background: Mogamulizumab is a humanized anti-CCR4 antibody approved for the treatment of mycosis fungoides and Sézary Syndrome. Despite almost universal expression of CCR4 in these diseases, many patients eventually develop resistance to mogamulizumab (moga). The mechanisms of resistance to moga have not been characterized. An understanding of the resistance mechanisms will shed light on the disease biology and inform selection of next line therapies and the development of future CCR4-directed treatments for patients with cutaneous T cell lymphoma (CTCL). Methods: We identified 19 patients with mycosis fungoides or Sezary syndrome in whom moga had been discontinued due to lack or loss of response to therapy. Archival blood and skin and/or lymph node biopsies after discontinuation of treatment were studied. Specimens collected prior to initiation of moga were also procured whenever available. CCR4 protein expression was determined by immunohistochemistry (IHC; clone L291H4; Biolegend). Targeted sequencing was performed using the Agilent XTHS2 platform (Agilent) with a custom Agilent SureSelect panel that included full coverage of the exonic regions of CCR4. Results: Fourteen patients had Sézary syndrome and five had mycosis fungoides. Twelve patients were classified as primary refractory to treatment and the remaining seven patients had secondary resistance. Median duration of treatment with moga was 3.5 months (range: 2-41). CCR4 expression was non-detectable in post-treatment specimens of 8 of 14 (57%) patients with evaluable specimens. Targeted DNA sequencing of post-treatment samples revealed novel coding mutations of CCR4 in three patients. Only one of the 3 mutations (L21V) overlapped with the known N-terminal mogamulizumab binding epitope. The other two mutations occurred in transmembrane domains (M116R, T161-W162 delinsSR). Two patients with mutations in CCR4 also had unequivocal copy number loss involving the CCR4 locus. Acquisition of CCR4 genomic alterations corresponded with lack of CCR4 expression by immunohistochemistry. In-vitro validation of the novel CCR4 mutations is ongoing and results from these experiments will be included in the final presentation. Conclusion: Overall our study indicates that potential loss of CCR4 expression, with or without underlying genomic aberrations, represents a major hurdle in the development of future CCR4 targeting strategies in CTCL. This finding has important implications for management and monitoring of cutaneous T cell lymphoma patients receiving CCR4 directed therapies. Disclosures Beygi: Kite/Gilead: Current Employment.

Abstract The Retinoid-X-Receptor specific retinoid bexarotene is approved for treatment of cutaneous T-cell lymphoma (CTCL) in the United States and Europe. CTCL is a heterogeneous group of peripheral non-Hodgkin lymphomas with different prognosis and different response to treatment and the current WHO classification contains nine different entities with Mycosis fungoides (MF) as the most common subtype. Since most data on efficacy and tolerability are available from studies with MF, this Dermatologic Cooperative Oncology Group (DeCOG) trial (ADO-CTCL-3) evaluates treatment response to bexarotene in patients with non-MF CTCL, encompassing CD30+ primary cutaneous ALCL and severe lymphomatoid papulosis (LyP), CD-30 negative pleomorphic TCL, Sezary's syndrome (SS), subcutaneous panniculitis-like TCL, and other defined variants. Additionally, patients with different rare variants of MF, including folliculotropic (fMF), granulomatous, erythrodermic, and CD30+ transformed MF were included. 200 patients with CTCL stage IB or higher and at least one prior treatment failure were registered in this trial with bexarotene at an initial daily dose of 150mg/m² orally und prophylactic fenofibrate medication. Bexatrotene was increased to a target dosage of 300 mg/m² in patients with tolarable serum lipids under these conditions. Patients were evaluated according to a standardized evaluation tool (tumor burden index; TBI) up to 24 weeks of of treatment or until progression occured. In responding patients, treatment could be continued until progression. After a central pathology board review process 2 patients needed to be excluded from evaluation because of misdiagnoses. Additional 11 patients could not be evaluated for response due to early withdrawal. Among the remaining patients there were 18 patients with SS, 8 cutaneous CD30+ ALCL, 10 Lyp, 9 other rare entities. In addition MF cases with folliculotropic subtype (18), CD30+ transformation (11), CD30- transformation (4), and a variety of other MF subtypes could be compared to the response in classical MF. Response to bexarotene could be confirmed in classical MF with an objective response (OR) rate of 37 percent (5% CR; 32% PR). Response rates for the other entities were as follows: CD30+ ALCL 50% OR, LyP 60% OR, SS 33% OR, other forms of CTCL together 33% OR. In MF with CD30+ transformation 46% responded, in contrast to only 11% of cases with folliculotropic MF. Tolerability was as expected with most grade III/IV toxicities limited to hyperlipidemia. Side effect management anf the incidence of serious adverse events could be substantially improved using standard algorithms for lipid control. In conclusion, this is one of the largest CTCL cohorts with exact pathological review worldwide evaluated for treatment response with bexarotene. Bexarotene appears to be a safe and effective treatment option also in non-classical MF and CTCL variants. Folliculotropic MF proved to be a difficult-to-treat entity and CD30 expression seems to be a favourable prognostic marker for treatment response.

Background: Cutaneous T cell lymphoma is incurable with current standard therapies and there is an urgent need for more effective therapies. BNZ-1 is a pegylated peptide antagonist that binds to the common gamma chain signaling receptor for cytokines IL-2, IL-9 and IL-15. We hypothesized that inhibition of these 3 cytokines could generate a therapeutic benefit to CTCL patients through a multipronged mechanism: 1) IL-2 and IL-15 inhibition blocks cytokine-driven propagation/survival of tumor cells 2) IL-2 and IL-9 inhibition lowers the activity of regulatory T-cells that may impede the anti-lymphoma immune response 3) IL-15 inhibition may provide an additional anti-inflammatory effect Methods: A multicenter, open-label Phase 1/2 study was completed to characterize the safety and efficacy of BNZ-1 (NCT03239392). Refractory patients, who have failed FDA-approved or investigational treatments appropriate for the stage of their disease, with a diagnosis of mycosis fungoides (MF) of any stage or Sézary syndrome (SS) were eligible for this trial. In part I of the study, Pts were enrolled in sequential dose cohorts of 0.5 mg/kg, 1mg/kg, 2 mg/kg, and 4 mg/kg to receive weekly intravenous dose of BNZ-1 to characterize safety, pharmacokinetics, pharmacodynamics, and evidence of antitumor activity. Thereafter, patients were enrolled on an extension phase for 3 months of weekly dosing of BNZ-1. Patients who achieved a response were eligible for a long-term extension arm. Blood samples were collected to assess the impact of BNZ-1 on PD biomarkers including Treg numbers and activation markers of cytotoxic T lymphocytes using FACS analysis. Results: In the dose ranging part of the study, 15 patients (stages IB and IVB) were enrolled across the 4 dose cohorts. All patients completed the first 4 weeks for safety of the study and 9 enrolled in the 3-month extension period and 3 continued in the long term extension (LTE) period for over a year. BNZ-1 showed activity in all doses as it was determined by early signs of clinical efficacy and PD biomarkers. Subsequently, we selected the 2 mg/kg based on PK/PD relationship and clinical efficacy and expanded to a total of 19 patients. Clinical efficacy was measured by mSWAT and Global Response Score (GRS) as defined previously (Olsen E. et al. 2011). Based on the best response, one patient (5%) achieved a complete response, eleven (58%) patients achieved a partial response (50% reduction over baseline) by the end of the study. 7 patients (37%) showed stable disease during the study period. No disease recurrence was observed during the study period. For those patients who responded to the therapy in the dose ranging part of the study, the mean duration of response was calculated to be 9.2 months. Overall, BNZ-1 was well tolerated and showed no serious treatment-related adverse events in this patient population. Furthermore, PD analysis revealed that BNZ-1 discernibly suppressed the inflammatory nature of CTLs in majority of patients that respond to BNZ-1 treatment as measured by reduction in their mSWAT scores Conclusion: BNZ-1, an IL-2, IL-9, and IL-15 inhibitor, may provide a novel treatment option for CTCL patients who relapsed or were refractory with conventional therapies with a favorable toxicity profile. The multifaceted approach of BNZ-1 leads to direct inhibition of malignant cells, activation of tumor immunity, and suppression of inflammation. Since BNZ-1 showed safety and efficacy in challenging rCTCL patient population, its further development in a phase 3 trial is planned.

Cutaneous T cell lymphoma (CTCL) is a CD4+ T cell malignancy of the skin with heterogeneous outcomes and limited treatment options. Monoclonal antibodies directed against PD-1, such as pembrolizumab, have shown impressive efficacy in multiple advanced malignancies, and are currently tested in clinical trials in patients with CTCL. Initial data indicate that about half of the patients experience treatment response, whereas the other half are non-responders. Non-responders can be further divided into patients with stable disease versus rapid progressors. It is currently unknown why some CTCL patients respond to pembrolizumab while others rapidly progress, and no predictive biomarkers are available. Single-cell analysis approaches to identify biomarkers of response, for example quantifying the expression of PD-1 on tumor cells vs. reactive immune cells, have not enabled stratification of patients. We therefore hypothesized that more complex spatial cellular interactions within the immune tumor microenvironment (iTME) of CTCL could provide insight into the mechanisms of pembrolizumab response and enable prediction. We applied CODEX (CO-Detection by indEXing) highly multiplexed tissue imaging to study the CTCL iTME in matched biopsies before and after pembrolizumab therapy in 7 responders and 7 non-responders (see the Figure). Using 54 markers simultaneously allowed discriminating malignant CD4+ tumor cells from reactive CD4+ T cells and identified 30 different cell clusters with spatial information, including an M2 macrophage cluster that was enriched in non-responders before therapy. Unexpectedly, in pembrolizumab responders compared to non-responders, PD-1 expression levels were higher in multiple clusters of tumor cells and reactive T cells. Computational spatial analysis revealed ten distinct, conserved cellular neighborhoods in the CTCL iTME that changed in composition and frequency during therapy. Interestingly, one cellular neighborhood to be presented dramatically increased after therapy only in responders. Therefore, highly multiplexed spatial analysis of the CTCL iTME allows discovering novel, predictive biomarkers of immunotherapy response and will pave the way for future studies that functionally address the identified cell types and cellular interactions.

Pdx Model

Cutaneous T cell lymphoma (CTCL) is an orphan disease and represents 3% of non-Hodgkin lymphomas. Mycosis fungoides and Sézary syndrome (MF/SS) are the most common subtypes of CTCL. The development of targeted therapies for orphan diseases is challenging, but particularly so in the case of MF/SS due to the lack of reliable preclinical models for this malignancy, which is limited to the skin at the early stage, but disseminated to lymph nodes and other organs as disease progresses. Here we report a novel patient-derived xenograft (PDX) mouse model of MF/SS that recapitulates the multi-compartmental nature of CTCL and a blood-based genetic biomarker assay for quantitative monitoring of systemic tumor burden in PDX mice. The PDX models were extensively characterized and exhibit cardinal clinical and histologic features of CTCL, including erythematous scaly skin lesions and eventual lymphomatous dissemination to the spleen and other organs, and maintain the molecular characteristics of their clinical counterparts. The malignant T cells harvested from spleen of PDX mice shared identical TCR sequences and immunophenotypes with corresponding MF/SS patient donor, which featured as losing CD7 and CD26 expression in CD4+ T cells. We also developed a quantitative assay of tumor burden in PDX mice by determining the amount of human β-actin cell-free DNA (cfDNA) in the plasma. The cfDNA levels in the plasma were increased in a linear fashion and correlated with the tumor growth post-implantation. To explore the utility of this PDX model for drug testing, we searched for novel agents for CTCL by performing a high-throughput screen of selected available targeted agents and identified phosphatidylinositol 3-kinase (PI3K) as a high value target. A PI3K inhibitor was advanced to our PDX model with favorable results including disease attenuation and survival prolongation. Further experiments using isoform-specific siRNA knockdowns and isoform-selective PI3K inhibitors identified PI3K-δ as the tumor-driving isoform. Additional studies showed synergistic combination of PI3K-δ inhibitors with histone deacetylase (HDAC) inhibitors. The particularly potent combination of copanlisib and panobinostat is proposed for further clinical development.

Gene Expression Analyses

Background: Aggressive non-Hodgkin lymphoma (NHL) relapsing after standard first line chemotherapy represents an unmet clinical need. Currently, a phase 1/2 study with the combination of pixantrone, etoposide, bendamustine, and in CD20 positive tumors, rituximab, in patients with relapsed aggressive NHL of B- or T- cell phenotype (the PREBEN study) is ongoing. Here our aim was to molecularly characterize samples from the PREBEN trial and find clinical correlates for predicting treatment response. Methods: The profiling cohort consisted of 21 patients with pre-treatment RNA samples and clinical data. Nanostring PanCancer Pathways and PanCancer Immune profiling panels (altogether 1348 genes) were utilized for the gene expression analyses. The findings from gene expression analyses were correlated with clinical parameters. Results: Fourteen patients had diffuse large B-cell lymphoma (DLBCL), whereas seven had peripheral T-cell lymphoma (PTCL). In general, the expression of DNA replication genes distinguished DLBCL from PTCL. Additionally, gene expression analyses identified genes having differential expression based on the response to the treatment. Supervised hierarchical clustering of the ten most differentially expressed genes could separate the responding (n=4) and non-responding (n=10) DLBCL patients into two distinct subgroups (Fig. 1A). Similarly, the responding (n=3) and non-responding (n=4) PTCL patients could be separated into distinct subgroups by supervised clustering with the ten most differentially expressed genes (Fig. 1B). Conclusion: Molecular profiles of aggressive NHL are heterogeneous and may be utilized for predicting the treatment response. More detailed molecular analyses are currently ongoing.
