RESUMEN
Antibodies targeting PD-1 or 4-1BB achieve objective responses in follicular lymphoma (FL), but only in a minority of patients. We hypothesized that targeting multiple immune receptors could overcome immune resistance and increase response rates in patients with relapsed/refractory FL. We therefore conducted a phase 1b trial testing time-limited therapy with different immunotherapy doublets targeting 4-1BB (utomilumab), OX-40 (ivuxolimab), and PD-L1 (avelumab) in combination with rituximab among patients with relapsed/refractory grade 1-3A FL. Patients were enrolled onto 2 of 3 planned cohorts (cohort 1 - rituximab/utomilumab/avelumab; cohort 2 - rituximab/ivuxolimab/utomilumab). 3+3 dose escalation was followed by dose expansion at the recommended phase 2 dose (RP2D). Twenty-four patients were enrolled (16 in cohort 1 and 9 in cohort 2, with one treated in both cohorts). No patients discontinued treatment due to adverse events and the RP2D was the highest dose level tested in both cohorts. In cohort 1, the objective and complete response rates were 44% and 19%, respectively (50% and 30%, respectively, at RP2D). In cohort 2, no responses were observed. The median progression-free survivals in cohorts 1 and 2 were 6.9 and 3.2 months, respectively. In cohort 1, higher density of PD-1+ tumor-infiltrating T-cells on baseline biopsies and lower density of 4-1BB+ and TIGIT+ T-cells in on-treatment biopsies were associated with response. Abundance of Akkermansia in stool samples was also associated with response. Our results support a possible role for 4-1BB agonist therapy in FL and suggest that features of the tumor microenvironment and stool microbiome may be associated with clinical outcomes (NCT03636503).

The ALLIANCE A041202 trial found that continuously administered ibrutinib in the first-line setting significantly prolonged progression-free survival compared with a fixed-duration treatment of rituximab and bendamustine in older adults with chronic lymphocytic leukemia (CLL). In this study, we created a Markov model to assess the cost-effectiveness of ibrutinib in the first-line setting, compared with a strategy of using ibrutinib in the third-line after failure of time-limited bendamustine and venetoclax-based regimens. We estimated transition probabilities from randomized trials using parametric survival modeling. Lifetime direct health care costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) were calculated from a US payer perspective. First-line ibrutinib was associated with an improvement of 0.26 QALYs and 0.40 life-years compared with using ibrutinib in the third-line setting. However, using ibrutinib in the first-line led to significantly higher health care costs (incremental cost of $612 700), resulting in an ICER of $2 350 041 per QALY. The monthly cost of ibrutinib would need to be decreased by 72% for first-line ibrutinib therapy to be cost-effective at a willingness-to-pay threshold of $150 000 per QALY. In a scenario analysis where ibrutinib was used in the second-line in the delayed ibrutinib arm, first-line ibrutinib had an incremental cost of $478 823, an incremental effectiveness of 0.05 QALYs, and an ICER of $9 810 360 per QALY when compared with second-line use. These data suggest that first-line ibrutinib for unselected older adults with CLL is unlikely to be cost-effective under current pricing. Delaying ibrutinib for most patients with CLL until later lines of therapy may be a reasonable strategy to limit health care costs without compromising clinical outcomes.

BACKGROUND: Ibrutinib is a small molecule tyrosine kinase inhibitor that blocks the activity of B cells and other immune effectors and is used in a variety of hematologic malignancies. There have been numerous reports of increased frequency of serious infections including invasive fungal infections (IFI) in patients on ibrutinib. METHODS: Demographic and clinical features of all patients receiving ibrutinib at a single tertiary care center were collected from electronic medical records. Univariate and multivariate statistical analyses were performed to find out the factors associated with infection. RESULTS: A total of 244 patients received ibrutinib for hematologic malignancies, of which 44 (18.0%) experienced ≥ 1 serious infection including 5 (2.0%) with IFI (1 pulmonary cryptococcosis, 4 pulmonary aspergillosis), 39 (16.0%) with bacterial infections and 8 (3.3%) with viral infections. Ten patients (4.1%) experienced multiple infections or co-infections while on ibrutinib and 10 (4.1%) expired or were transferred to hospice as a result of infection. In multivariate analysis risk factors that were less common in uninfected versus infected patients included advanced age (73 years vs. 77 years), Eastern Cooperative Oncologic Grade (ECOG) performance score ≥ 2 (6.5% vs. 31.8%) and concurrent use of steroids (4.5% vs. 20.5%) or other cytotoxic agents (0% vs. 4.6%). CONCLUSIONS: There was a high rate of serious infection but relatively few IFI in patients receiving ibrutinib. Most patients who developed serious infections while on ibrutinib had additional predisposing risk factors including concurrent use of steroids or other cytotoxic agents, advanced age and frailty.

BACKGROUND: Current guidelines recommend adding vancomycin to empiric treatment of FN in patients who meet specific criteria. After 48 hours, the guidelines recommend discontinuing vancomycin if resistant Gram-positive organisms are not identified. Based on these recommendations, a vancomycin stewardship team defined criteria for discontinuation of vancomycin at 48 hours and increased surveillance of vancomycin usage through a multimodal approach. The purpose of this retrospective analysis is to assess the impact of this multimodal approach on the discontinuation of empiric vancomycin at 48 hours in FN. METHODS: This retrospective analysis included a pre- and post-intervention cohort of 200 HSCT recipients with FN from 2015 to 2018. Criteria for continued vancomycin use beyond 48 hours included culture-documented resistant Gram-positive infection, positive Methicillin-Resistant S aureus (MRSA) nasal swab with evidence of pneumonia, or hemodynamic instability with concern for sepsis. The following patient characteristics were collected: previous MRSA infection, MRSA nasal swab collection and results, culture results, duration of vancomycin use, rationale for continuation of vancomycin beyond 48 hours, and re-initiation of vancomycin. RESULTS: In the post-intervention cohort, vancomycin discontinuation at 48 hours increased from 31% (95% CI 21.94-40.05) to 70% (95% CI 61.02-78.97; P < 0.0001). An additional 23% of vancomycin orders were discontinued at 72 hours. Off criteria vancomycin use decreased from 33% in pre to 1% in the post-implementation cohort. CONCLUSION: Establishing define criteria for vancomycin use in FN patients with a multimodal approach of physicians from hematology and infectious diseases, clinical pharmacists and the antibiotic stewardship team significantly improved vancomycin discontinuation.

PURPOSE: Carmustine (BCNU) is used in the conditioning regimens BEAM and CBV for autologous stem cell transplantation. Carmustine-related infusion reactions, while not described in the BEAM literature, occurred in 95 % of patients who received CBV. The most common symptoms include flushing, facial pain, headache, and hypotension. These reactions have been attributed to the absolute ethanol that is used in the reconstitution process or alternatively by a direct effect of carmustine. It is currently recommended that carmustine 300 mg/m2 be infused over at least 100 min (3-5 mg/m2/min). Prior to October 2014, carmustine infusions were given over 90 min but were changed to 120 min based on the above recommendation. We compared the two infusion rates in patients receiving BEAM to see if lengthening the infusion decreased the frequency of reactions. METHODS: Overall, 100 patients received BCNU as part of BEAM or Zevalin BEAM and were equally divided between 90 and 120 min infusion times. The primary outcome was the incidence of infusion-related reactions which were graded based on CTCAE 4.03 descriptions of flushing and infusion-related reactions. We also evaluated the impact of premedication as well as the efficacy of medications used to treat infusion reactions. RESULTS: Between the years 2013-2016, there were 50 patients who received BCNU over 90 min and 50 patients over 120 min. There were no significant differences observed for diagnosis, age and gender between the two groups. Twenty-eight (56 %) in the 90-min and 26 (52 %) in the 120-min infusion intervals developed a reaction (p = 0.6882). Of the patients that developed a reaction, 19 patients (67 %) in the 90-min and all 26 patients (100 %) in the 120-min infusion were given premedications predominately acetaminophen, in addition to dexamethasone. Among reacting patients, 57 % of the 90-min and 65 % of the 120-min groups received additional intervention (p = 0.53). CONCLUSION: Infusion reactions during high-dose BCNU are common and are not clearly reduced by modestly extending the duration of infusion or giving premedications.

High upfront cost may be a barrier to adopting chimeric antigen receptor T-cell (CAR-T) therapy for relapsed or refractory B-cell lymphoma. Data on the real-world costs are limited. Using the Blue Cross Blue Shield Axis database, we evaluated 271 commercially insured patients who received CAR-T therapy for B-cell lymphoma (median age = 58 years; men = 68%; diffuse large B-cell lymphoma = 87%; inpatient CAR-T therapy = 85%). Our peri-CAR-T period of interest was from 41 days before to 154 days after CAR-T therapy index divided into seven 28-day intervals. Median total costs were $608â100 (interquartile range, IQR = $534â100-$732â800); 8.5% of patients had total costs exceeding $1 million. The median cost of CAR-T therapy products was $402â500, and the median out-of-pocket copayment was $510. Monthly costs were highest during the month of CAR-T therapy administration (median = $521â500), with median costs below $25â000 in all other 28-day intervals. Costs of CAR-T therapy use were substantial, largely driven by product acquisition. Future studies should examine the relationship between costs, access, and financial outcomes.

Outcomes are poor for patients with relapsed and/or refractory (R/R) large B-cell lymphoma (LBCL) post chimeric antigen receptor T-cell (CAR-T) therapy. Two CD19-directed therapies, tafasitamab- cxix plus lenalidomide (tafa-len) and loncastuximab tesirine (loncaT) are approved in R/R LBCL. The efficacy of these CD19 directed therapies in patients who relapse after CD19 directed CAR-T (CD19-CART) therapy is not well understood. We conducted a multi-center study of patients with R/R LBCL that received either tafa-len or loncaT at any timepoint for R/R disease after CD19-CART therapy. Fifty-three patients were included in this study with the median follow up of 56 (9.1-199) weeks from CAR-T infusion. Median number of systemic therapies pre-CAR-T therapy was 3 (range: 1-6); axicabtagene ciloleucel was the most utilized CAR-T product (n = 32,60%). Median time from CAR-T therapy to tafa-len or loncaT was 7.3 (1.2-38.2) months with median number of lines of therapy between CAR-T therapy and these regimens of 1 (0-5). Combined overall response rate and complete response rates were 27% and 10%, respectively. Median duration of response was 13.3 (2.1-56.7) weeks. In this real-world study, the use of currently approved CD19-directed therapies to treat R/R LBCL after CD19-CAR-T therapy showed limited clinical activity and duration of responses.

Follicular lymphoma (FL) is traditionally considered treatable but incurable. In March 2021, the US Food and Drug Administration approved the use of chimeric antigen receptor (CAR) T-cell therapy in patients with relapsed or refractory (R/R) FL after ≥2 lines of therapy. Priced at $373 000, CAR T-cell therapy is potentially curative, and its cost-effectiveness compared with other modern R/R FL treatment strategies is unknown. We developed a Markov model to assess the cost-effectiveness of third-line CAR T-cell vs standard of care (SOC) therapies in adults with R/R FL. We estimated progression rates for patients receiving CAR T-cell and SOC therapies from the ZUMA-5 trial and the LEO CReWE study, respectively. We calculated costs, discounted life years, quality-adjusted life years (QALYs), and the incremental cost-effectiveness ratio (ICER) of CAR T-cell vs SOC therapies with a willingness-to-pay threshold of $150 000 per QALY. Our analysis was conducted from a US payer's perspective over a lifetime horizon. In our base-case model, the cost of the CAR T-cell strategy was $731 682 compared with $458 490 for SOC therapies. However, CAR T-cell therapy was associated with incremental clinical benefit of 1.50 QALYs, resulting in an ICER of $182 127 per QALY. Our model was most sensitive to the utilities associated with CAR T-cell therapy remission and third-line SOC therapies and to the total upfront CAR T-cell therapy cost. Under current pricing, CAR T-cell therapy is unlikely to be cost-effective in unselected patients with FL in the third-line setting. Both randomized clinical trials and longer term clinical follow-up can help clarify the benefits of CAR T-cell therapy and optimal sequencing in patients with FL.

During the COVID-19 pandemic, hematopoietic stem cell transplant (HSCT) recipients faced an elevated mortality rate from SARS-CoV-2 infection, ranging between 10-40%. The SARS-CoV-2 mRNA vaccines are important tools in preventing severe disease, yet their efficacy in the post-transplant setting remains unclear, especially in patients subjected to myeloablative chemotherapy and immunosuppression. We evaluated the humoral and adaptive immune responses to the SARS-CoV-2 mRNA vaccination series in 42 HSCT recipients and 5 healthy controls. Peripheral blood mononuclear nuclear cells and serum were prospectively collected before and after each dose of the SARS-CoV-2 vaccine. Post-vaccination responses were assessed by measuring anti-spike IgG and nucleocapsid titers, and antigen specific T cell activity, before and after vaccination. In order to examine mechanisms behind a lack of response, pre-and post-vaccine samples were selected based on humoral and cellular responses for single-cell RNA sequencing with TCR and BCR sequencing. Our observations revealed that while all participants eventually mounted a humoral response, transplant recipients had defects in memory T cell populations that were associated with an absence of T cell response, some of which could be detected pre-vaccination.
RESUMEN
INTRODUCTION: Peripheral T-Cell Lymphomas (PTCL) are a rare subgroup of lymphomas with a poor outcome.Traditional prognostic measures rely heavily on disease stage, and with the advent of targeted treatment, further stratificationcriteria are needed to guide treatment. To date, the impact of blood involvement at diagnosis on outcomes has not been assessed. MATERIALS AND METHODS: We retrospectively reviewed blood involvement by flow cytometry at diagnosis in 102 consecutivelytreated patients who had flow cytometry data available at diagnosis. Of these, 78 patients with nodal subtypes were identified andstudied in this analysis. RESULTS: Of 78 patients with nodal subtypes of PTCL who had flow data available at the time ofdiagnosis, circulating populations of malignant T cells matching those in the biopsied lymph nodes were found in 21 patients bymultiparameter flow cytometry. A positive flow cytometry was highly correlated with bone marrow involvement. The patientswith a negative flow cytometry had a trend toward a longer median PFS compared to those with a positive flow but there was noimpact on overall survival. CONCLUSIONS: Circulating malignant tumor cells can be found in the peripheral blood in a subset ofpatients with aggressive nodal T-cell lymphomas, including peripheral t-cell lymphoma not otherwise specified andangioimmunoblastic T-cell lymphomas, and blood involvement is correlated with bone marrow involvement.

The multicenter, phase Ib CC-122-DLBCL-001 dose-expansion study (NCT02031419) explored the cereblon E3 ligase modulator (CELMoD) agent avadomide (CC-122) plus rituximab in patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL). Patients received avadomide 3 mg/day 5 days on/2 days off plus rituximab 375 mg/m2 on day 8 of cycle 1, day 1 of cycles 2 through 6, and day 1 of every third subsequent cycle for 2 years. Primary endpoints were safety and tolerability; preliminary efficacy was a secondary endpoint. A total of 68 patients were enrolled (DLBCL [n = 27], FL [n = 41; 31 lenalidomide-naïve, 10 lenalidomide-treated]). Median age was 62 years (range, 33-84 years), and patients had received a median of 3 (range, 1-8) prior regimens. Among patients with DLBCL, 66.7% had primary refractory disease (partial response or less to initial therapy). Among patients with FL, 65.9% were rituximab-refractory at study entry and 10.0% were lenalidomide-refractory. The most common any-grade avadomide-related adverse events (AEs) were neutropenia (63.2%), infections/infestations (23.5%), fatigue (22.1%), and diarrhea (19.1%). The most common grade 3/4 avadomide-related AEs were neutropenia (55.9%) infections/infestations (8.8%), and febrile neutropenia (7.4%). In patients with DLBCL, overall response rate (ORR) was 40.7% and median duration of response (mDOR) was 8.0 months. In patients with FL, ORR was 80.5% and mDOR was 27.6 months; response rates were similar in lenalidomide-naïve and -treated patients. Avadomide plus rituximab was well tolerated, and preliminary antitumor activity was observed in patients with R/R DLBCL and FL, including subgroups with typically poor outcomes. These results support further investigation of novel CELMoD agents in combination with rituximab in R/R DLBCL and FL.
RESUMEN
There is a need for additional treatment options for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who do not benefit from available therapies. We examined combinations of the cereblon E3 ligase modulator (CELMoD) agent avadomide (CC-122), the selective, ATP-competitive mammalian target of rapamycin kinase inhibitor CC-223, and the potent, selective, covalent Bruton tyrosine kinase inhibitor CC-292 in patients with relapsed/refractory (R/R) DLBCL. In the multicenter, phase Ib CC-122-DLBCL-001 study (NCT02031419), the dose-escalation portion explored combinations of CC-122, CC-223, and CC-292 administered as doublets or triplets with rituximab in patients with chemorefractory DLBCL. Primary endpoints were safety, tolerability, and dose-limiting toxicities; additional endpoints included pharmacokinetics, pharmacodynamics, biomarkers, and preliminary efficacy. As of December 1, 2017, 106 patients were enrolled across four cohorts. The median age was 65 years (range 24-84 years), and patients had a median of 3 (range 1-10) prior to regimens. A total of 101 patients (95.3%) discontinued, most commonly due to disease progression (49.1%). The most common any-grade adverse events (AEs) across treatment arms were gastrointestinal and hematologic; the most common grade 3/4 AEs were hematologic. CC-122 was well tolerated, with no unexpected safety concerns. Preliminary efficacy was observed in three of four treatment arms. CC-122 plus rituximab was considered suitable for dose expansion, whereas CC-223 and CC-292 combinations were associated with enhanced toxicity and/or insufficient improvement in responses. CC-122 plus rituximab was well tolerated, with preliminary antitumor activity in patients with R/R DLBCL. This innovative study demonstrates the feasibility of assessing the tolerability and preliminary efficacy of novel combinations utilizing a multi-arm dose-finding design.
RESUMEN
Intratumoral injection of G100, a toll-like receptor 4 (TLR4) agonist, was shown pre-clinically to stimulate anti-tumor immune responses and tumor regression. This open-label, multicenter, phase 1/2 trial evaluated the safety, tolerability, and preliminary efficacy of intratumoral G100 injections following localized low-dose radiation in patients with follicular lymphoma (ClinicalTrials.gov #NCT02501473). The study was comprised of a G100 dose escalation (5 or 10 µg/dose, or 20 µg/dose for large tumors); a randomized component comparing G100 to G100 plus pembrolizumab; and G100 20 µg/dose expansion. Adverse events grade ≥3 were uncommon in patients treated with G100, and no unexpected toxicities were observed when combined with pembrolizumab. G100 20 µg (n = 18) resulted in an overall response rate of 33.3% and abscopal tumor regression in 72.2% of patients. This early-phase study provides a foundation for combining an intratumoral TLR4 agonist with agents to produce immune-mediated responses in follicular lymphoma with limited added toxicity.

Thrombotic thrombocytopenic purpura (TTP) is a rare but frequently fatal complication of SLE. It occurs in the context of both active and inactive lupus and carries a worse overall prognosis than idiopathic acquired TTP. Recent advances in the knowledge and treatment of TTP do not seem to have brought similar improvements in the management and outcome of TTP in SLE. The illumination of the role of the von Willebrand factor multimer protease, ADAMTS13 in idiopathic TTP continues to enhance our comprehension of the pathogenesis of the disease and has contributed to improvements in diagnosis and management. We explore the overlap of TTP and SLE, and discuss the current understanding of the involvement of ADAMTS13 and its implications for patients with this uncommon form of microangiopathic haemolytic anaemia.

PURPOSE: Intravenous immune globulin (IVIG) therapy is used in patients with hypogammaglobulinemia to lower the risk of infections. IVIG and subcutaneous IVIG (SCIG) therapy have been to shown to be safe and effective when administered as clinic-based infusions. Concern from both patients and providers for increased transmission of the coronavirus disease 2019 (COVID-19) virus to immunosuppressed patients with scheduled medical visits and procedures made it necessary for us to reassess our process of how we manage patient care in general and chronic clinic infusions in particular. Here we describe our experience of transitioning patients from clinic-based to home based IVIG and/or SCIG infusions to decrease the risk of COVID-19 exposure. METHODS: Criteria were developed to identify high-risk immunosuppressed patients who would be appropriate candidates for potential conversion to home based IVIG infusions. Data were collected via chart review, and cost analysis was performed using Medicare Part B reimbursement data. A patient outcome questionnaire was developed for administration through follow-up phone calls. RESULTS: From March to May 2020, 45 patients met criteria for home-based infusion, with 27 patients (60%) agreeing to home-based infusion. Posttransition patient outcomes assessment, conducted in 26 patients (96%), demonstrated good patient understanding of the home-based infusion process. No infusion-related complications were reported, and 24 patients (92%) had no concerns about receiving future IVIG and/or SCIG doses at home. No patient tested positive for COVID-19 during the study period. Clinic infusion visits decreased by 26.6 visits per month, resulting in a total of 106 hours of additional available infusion chair time per month and associated cost savings of $12,877. CONCLUSION: Transition of clinic based to home based IVIG/SCIG infusion can be successfully done to decrease potential exposure during a pandemic in a high-risk immunosuppressed population, with no impact on patient satisfaction, adherence, or efficacy. The home-based infusion initiative was associated with a reduction in costs to patients and an increase in available chair time in the infusion clinic.

A recent phase II trial showed that use of polatuzumab vedotin in combination with bendamustine plus rituximab (Pola-BR) in transplant-ineligible patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL) resulted in longer progression-free survival and overall survival compared to bendamustine plus rituximab (BR) alone. In this study, we constructed a Markov model to assess the cost-effectiveness of Pola-BR versus BR in transplant-ineligible R/R DLBCL. We calculated the incremental cost-effectiveness ratio (ICER) of each treatment strategy from a US payer perspective, using a lifetime horizon and a willingness-to-pay threshold of $100,000 per quality-adjusted life-year (QALY). Use of Pola-BR was associated with an incremental cost of $92,641 compared to BR alone ($200,905 vs $108,265, respectively), an incremental effectiveness of 1.76 QALYs (2.35 vs 0.59 QALYs, respectively), and an ICER of $52,519/QALY. These data suggest that use of Pola-BR for R/R DLBCL is likely to be cost-effective compared to BR alone.

Severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) has a high death rate in patients with comorbidities or in an immunocompromised state. We report a mild and attenuated SARS CoV-2 infection in a patient who is 17 months post stem cell transplantation and maintained on the JAK/STAT inhibitor ruxolitinib, a proposed novel therapy for SARS CoV-2 pneumonia.

We report results on 23 patients with cutaneous T cell lymphoma (7 primary cutaneous γδ T cell lymphoma [PCGDT], 16 mycosis fungoides/Sézary syndrome [MF/SS]) who underwent allogeneic stem cell transplantation. All pts had skin involvement, 14 had total skin electron beam before conditioning. Donors were 10/10 HLA matched related (13), 5/10 haploidentical (4), and matched unrelated (5) or mismatched unrelated (1). Thirteen were in a clinical complete remission at the time of transplant. The 100-day transplant related mortality for the MF/SS and PCGDT patients was 12% and 29%, respectively. At a median follow up of 5.5 years, the overall survival and disease-free survival for MF/SS patients was 75% and 64%, respectively, and 6 of 10 MF/SS pts in long term complete response had a partial response at the time of transplant. Of seven PCGDT patients, four of seven are alive at a median follow up of 5 years and three are disease-free.
