RESUMEN
This systematic literature review evaluated frontline treatment burden in pediatric and adolescent/young adult (AYA) patients with high-risk classical Hodgkin lymphoma (cHL) among studies originating from the United States. Data were extracted from 32 publications (screened: total, n = 3115; full-text, n = 98) representing 12 studies (randomized controlled trials [RCTs], n = 2; non-comparative, non-randomized, n = 7; observational, n = 3). High-risk disease definitions varied across studies. Five-year event-free survival (EFS)/progression-free survival (PFS) was 86%-100% and 79%-94%, and complete response rates were 35%-100% and 5%-64% for brentuximab vedotin (BV)-containing and chemotherapy-alone regimens, respectively. In identified RCTs, BV-containing compared with chemotherapy-alone regimens demonstrated significantly longer 3-year EFS/5-year PFS. Hematological and peripheral neuropathy were the most commonly reported adverse events of interest, although safety data were inconsistently reported. Few studies evaluated humanistic and no studies evaluated economic burden. Results from studies with the highest quality of evidence indicate an EFS/PFS benefit for frontline BV-containing versus chemotherapy-alone regimens for pediatric/AYA patients with high-risk cHL.

We explored patient front-line treatment preferences in newly diagnosed stage III/IV classic Hodgkin lymphoma (cHL). The CONNECT patient survey, administered online from 30 December 2020 to 1 March 2021, examined preferences overall and by age at diagnosis in 182 adult patients diagnosed with stage III/IV cHL within the past 10 years in the United States. At diagnosis, patients' median age was 36 years; 66% of patients were younger (aged 16-41 years) and 34% older (aged 42-85 years). When asked about initial treatment goals, 74% of patients ranked cure as their first or second goal (86% younger vs. 52% older patients; p < 0.001). At diagnosis, 72% of patients preferred aggressive treatment, and 85% were willing to accept more short-term risks in exchange for a better-working therapy long term. For long-term risks, younger versus older patients were significantly more concerned about second cancers (p < 0.001) and fertility issues (p = 0.007), whereas older patients were more concerned about lung damage (p = 0.028) and infections (p < 0.001). Most patients (94%) reported having a caregiver at some point, but 99% of these patients retained some control of treatment decisions. Collectively, these survey results highlight patient treatment preferences and differences in treatment goals and long-term side effect concerns based on patient age.

Aim: To understand US physicians' frontline (1L) treatment preferences/decision-making for stage III/IV classic Hodgkin lymphoma (cHL). Materials & methods: Medical oncologists and/or hematologists (≥2 years' practice experience) who treat adults with stage III/IV cHL were surveyed online (October-November 2020). Results: Participants (n = 301) most commonly considered trial efficacy/safety data and national guidelines when selecting 1L cHL treatments. Most physicians (91%) rated overall survival (OS) as the most essential attribute when selecting 1L treatment. Variability was seen among regimen selection for hypothetical newly diagnosed patients, with OS cited as the most common reason for regimen selection. Conclusion: While treatment selection varied based on patient characteristics, US physicians consistently cited OS as the top factor considered when selecting a 1L treatment for cHL.
Classic Hodgkin lymphoma (cHL) is a type of cancer that grows in lymph nodes. The researchers created a survey to assess how doctors in the USA choose medicine to treat patients who are newly diagnosed with an advanced stage of cHL (stage 3 or 4 out of 4 stages). We surveyed 301 doctors who treat patients with cHL. When choosing a medicine to treat cHL, most doctors said they consider results from research studies, how well the medicine works, information on the medicine's safety and recommendations in official guidelines. Most doctors said that overall survival (how long the patient survives after being diagnosed with cHL) is the most important outcome they consider when choosing a medicine to treat cHL. During the survey, doctors saw four unique patient profiles. These profiles differed in age, disease stage (how far along the cHL is) and other illnesses the patient has. While medicine choice was different across profiles, overall survival was still the reason for choosing each individual patient's medicine. These survey results show that doctors in the USA highly consider overall survival when choosing medicine for patients newly diagnosed with an advanced stage of cHL.

INTRODUCTION/BACKGROUND: Primary cutaneous anaplastic large-cell lymphomas (pcALCLs) are a type of cutaneous T-cell lymphoma (CTCL) in which CD30 is uniformly expressed. In mycosis fungoides (MF), another CTCL, CD30 is heterogeneously expressed. In ALCANZA, patients with pcALCLs or CD30-positive MF randomized to brentuximab vedotin (BV) vs. physician's choice of methotrexate or bexarotene had significantly improved outcomes, including higher objective response rates (ORR) lasting ≥4 months (ORR4), as well as longer median progression-free survival (PFS) and time to next treatment (TTNT). In this study, we sought to assess the real-world impact of treatment with BV in second or later lines of therapy for CTCL. MATERIALS AND METHODS: This retrospective chart review describes patient characteristics, treatment patterns, clinical outcomes, and healthcare resource use (HRU) in patients with pcALCLs or MF previously treated with ≥1 systemic therapy and subsequently treated with BV (n = 139) or other standard therapy (OST; n = 164). RESULTS: Most patients in the BV cohort (96.4%) received BV as second-line (2L) systemic therapy. The most common OSTs were methotrexate (11.6%), mogamulizumab (9.1%), and bendamustine (9.1%) monotherapies. For 2L BV and OST, median duration of therapy was 8.4 and 5.2 months, real-world ORR was 82.1% and 66.5%, and real-world ORR4 was 42.5% and 25.0%. Real-world 1- and 2-year PFS, TTNT, and OS were significantly longer (all P < .01) and HRU was lower for BV vs. OST. CONCLUSION: These real-world outcomes are consistent with ALCANZA results, demonstrating favorable outcomes with BV vs. OST in patients with CTCL previously treated with ≥1 systemic therapy.

PURPOSE: As part of the CONNECT study, we evaluated the caregiver role in treatment decision-making when caring for patients with classic Hodgkin lymphoma (cHL) in the USA. METHODS: The CONNECT caregiver survey was administered online December 2020-March 2021 to self-identified adult caregivers of cHL patients recruited from patient referrals and online panels. The caregiver's role in treatment decision-making, health-related quality of life (HRQoL, PROMIS-Global), and work impacts (WPAI:CG) were assessed. RESULTS: We surveyed 209 caregivers (58% women; median age 47 years; 54% employed; 53% spouse/partner); 69% of patients cared for were diagnosed with cHL in the past 1-2 years, with 48% having stage III/IV cHL and 29% in remission. More spouse/partner than other caregivers were involved in caregiving at symptom onset (61% vs 27%), whereas more other than spouse/partner caregivers began after first treatment (34% vs 5%). Cure, caregivers' top treatment goal (49%), was rated higher by spouse/partner than other caregivers (56% vs 42%). More spouse/partner than other caregivers were involved in treatment option discussions with physicians (52% vs 28%), were involved in patients' treatment decisions (54% vs 23%), and were aligned with patients' treatment goals (93% vs 79%). While caregivers reported HRQoL similar to that of the general population, nearly 30% of employed caregivers reported work impairment. CONCLUSION: Cure was caregivers' top treatment goal. Spouse/partner vs other caregivers were more involved, were involved earlier, and reported greater alignment with patient treatment goals and decision-making. Caregivers reported good HRQoL; however, caregiving impacted work productivity regardless of patient relationship.

PURPOSE: To evaluate the use of interim positron emission tomography-computed tomography (PET-CT) scans and Deauville 5-point scale (5PS) score reporting for stage III/IV classic Hodgkin lymphoma (cHL) treated frontline (1L) in community oncology settings. METHODS: This retrospective, observational study included adults with stage III/IV cHL initiating 1L doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD), brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine, or an escalated dosing regimen of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone within the US Oncology Network between January 2017 and October 2019. Data were collected from electronic health records and chart reviews and summarized descriptively. RESULTS: A total of 262 patients were included; 48.9% were age 39 years or younger. Most were male (57%), White (59%), had an International Prognostic Score <4 (76%), and received 1L ABVD (74%). Forty-nine percent of patients had stage III and 51% had stage IV cHL. Of 258 patients with ≥1 PET-CT scan, 71% (n = 184) had an interim scan and 64% received ≥1 scan at an off-site location. Of patients treated 1L with ABVD who received a baseline and interim scan, Deauville 5PS scores were not documented for 45% of patients; in 90% of these cases, a standardized uptake value (SUV) was reported. CONCLUSION: In community oncology settings, under-reporting of Deauville 5PS scores for interim PET-CT scans was observed. In the absence of Deauville 5PS scores, SUV results were generally provided. These results highlight educational opportunities that exist for PET-adapted ABVD, including consistency in reporting/utilization of Deauville 5PS scores to de-escalate or escalate treatment.

The six-year ECHELON-1 update showed a survival advantage for frontline (1 L) A + AVD (brentuximab vedotin, doxorubicin, vinblastine, dacarbazine) vs ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) for stage III/IV classic Hodgkin lymphoma (cHL). As clinical trials have limited ability to track patients for extended periods, we developed an oncology simulation model using ECHELON-1 data to estimate population-based cHL outcomes in the US over 10 years (through 2031). The model included a scenario without (64.5% ABVD, 35.5% PET-adapted ABVD utilization) and scenarios with 1 L A + AVD (27%-80%k utilization). At 27%-80% A + AVD utilization, the model estimated 13.6%-31.7% fewer deaths, 2.4%-6.3% more patients ≥5 years progression free, 9.4%-24.4% fewer stem cell transplants (SCTs), and 7.8%-22.5% fewer second cancers over 10 years. These results suggest that the improved outcomes observed in the ECHELON-1 update with A + AVD vs ABVD may translate to more patients alive and fewer with primary relapsed/refractory cHL, SCTs, and second cancers.

In newly diagnosed stage III/IV classic Hodgkin lymphoma (cHL), A+AVD (brentuximab vedotin, doxorubicin, vinblastine, dacarbazine) improved overall survival (OS) versus ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine). As clinical trial and real-world populations may differ, real-world treatment characteristics and OS (rwOS) were assessed for patients with stage III/IV cHL treated with frontline ABVD. This retrospective, observational analysis of deidentified electronic health record data (1/1/2011-8/31/2020) evaluated baseline disease and clinical characteristics, treatment patterns, and rwOS in patients with stage III/IV cHL treated with frontline ABVD. Data for 167 patients were analyzed. A median of 6 ABVD cycles were received. Baseline/interim positron emission tomography (PET) scans were obtained for 60.5%/89.8% of patients. Of patients diagnosed in 2016 or later (n = 73), 89% received an interim PET scan; 15/46 patients with no documented Deauville score, 6/15 with a score of 1 to 3, and 3/4 with a score of 4 to 5 de-escalated to AVD. Following frontline ABVD, 55.1% of patients received subsequent systemic therapy and 31.7% stem cell transplantation (SCT). At a median follow-up of 31.8 months, 82.0% of patients were alive (median rwOS, 101.2 months). Patients with stage III/IV cHL treated with frontline ABVD in the real world versus in clinical trials receive more subsequent therapy, including SCTs. Interim PET scans and Deauville scores were not universally obtained after treatment cycle 2, yet treatment de-escalation was observed. Patients with stage III/IV cHL may benefit from frontline A+AVD versus ABVD, as it improves OS and reduces the burden of subsequent therapy, including SCTs.

BACKGROUND: Since Food and Drug Administration approval of brentuximab vedotin in combination with cyclophosphamide, doxorubicin, and prednisone (Aâ +â CHP) as initial therapy for previously untreated CD30-expressing peripheral T-cell lymphoma (PTCL), there has been limited research on real-world patient characteristics, treatment patterns, and clinical outcomes. METHODS: We retrospectively analyzed claims of patients with PTCL treated with frontline Aâ +â CHP or CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) using the Symphony Health Solutions database. Adults with International Classification of Diseases-9/10 PTCL diagnosis codes who initiated Aâ +â CHP or CHOP between November 2018 and July 2021 were included. A 1:1 propensity score matching analysis was performed that adjusted for potential confounders between groups. RESULTS: A total of 1344 patients were included (Aâ +â CHP, nâ =â 749; CHOP, nâ =â 595). Before matching, 61% were men; median age at index was 62 (Aâ +â CHP) and 69 (CHOP) years. The most common Aâ +â CHP-treated PTCL subtypes were systemic anaplastic large cell lymphoma (sALCL; 51%), PTCL-not otherwise specified (NOS; 30%), and angioimmunoblastic T-cell lymphoma (AITL; 12%); the most common CHOP-treated subtypes were PTCL-NOS (51%) and AITL (19%). After matching, similar proportions of patients treated with Aâ +â CHP and CHOP received granulocyte colony-stimulating factor (89% vs. 86%, Pâ =â .3). Fewer patients treated with Aâ +â CHP received subsequent therapy than CHOP overall (20% vs. 30%, Pâ <â .001) and specifically with the sALCL subtype (15% vs. 28%, Pâ =â .025). CONCLUSIONS: Characteristics and management of this real-world PTCL population who were older and had a higher comorbidity burden than that in the ECHELON-2 trial demonstrate the importance of retrospective studies when assessing the impact of new regimens on clinical practice.

PURPOSE: We surveyed oncologists who treat classic Hodgkin lymphoma (cHL) as part of the CONNECT study to understand the treatment decision-making process, including the impact of positron emission tomography/computed tomography (PET/CT) imaging. METHODS: US physicians self-identifying as oncologists, hematologists, or hematologists/oncologists with ≥2 years of practice experience who treated ≥1 adult with stage III/IV cHL in the frontline setting in the last year were surveyed (October 19-November 16, 2020). Physician demographics, guideline adherence, and PET/CT utilization, interpretation, and access barriers were assessed. RESULTS: In total, 301 physicians participated in the survey. Eighty-eight percent of physicians gave somewhat-to-significant consideration to NCCN guidelines. Most physicians (94%; n = 284) reported obtaining a PET/CT scan at diagnosis; of these physicians, 97% reported obtaining an interim PET/CT scan for stage III/IV cHL, with 65% typically obtaining an interim PET/CT scan after cycle 2. The Deauville 5-point scale (5PS) was the primary scoring system used to review PET/CT results by 62% of physicians, with a positive score defined as ≥3 by 44%, ≥4 by 37%, and ≥2 by 12% of physicians. Fifty-five percent of physicians reported difficulty in obtaining PET/CT scans. CONCLUSION: Although most physicians considered NCCN guidelines when treating patients with stage III/IV cHL, interim PET/CT scans after cycle 2 were not universally obtained. When PET/CT scans were obtained, Deauville 5PS scores were not always provided, and variability existed on what defined a positive score. These findings suggest that opportunities exist for education and improved PET-adapted treatment approaches.

PURPOSE: Chemoimmunotherapy for patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) is largely unchanged for decades. Both preclinical models and clinical data suggest the combination of lenalidomide and ibrutinib may have synergy in DLBCL, particularly in the non-germinal center B-cell-like subset. METHODS: We enrolled 60 patients with newly diagnosed non-germinal center B-cell-like DLBCL in this investigator-initiated, single-arm phase II trial of rituximab, lenalidomide, and ibrutinib (RLI) with the sequential addition of chemotherapy (ClinicalTrials.gov identifier: NCT02636322). Patients were treated with rituximab 375 mg/m2 intravenous once on day 1, lenalidomide 25 mg once per day on days 1-10, and ibrutinib 560 mg once daily continuously of each 21-day cycle (RLI). After two cycles, standard chemotherapy was added to RLI for six additional cycles. The primary end points were overall response rate (ORR) after two cycles of RLI alone and complete response rate after completion of RLI with chemotherapy. In evaluable samples, circulating tumor DNA and DLBCL90 assays were performed. RESULTS: The median age was 63.5 years (range, 29-83 years) with 28% age 70 years or older. The revised international prognostic index identified 42% as high risk, and 62% were double expressor of MYC and BCL2 protein. The ORR after two cycles of RLI was 86.2%, and the complete response rate at the end of RLI-chemotherapy was 94.5%. With a median follow-up of 31 months, the progression-free survival and overall survival were at 91.3% and 96.6% at 2 years, respectively. CONCLUSION: Smart Start is the first study, to our knowledge, to treat newly diagnosed DLBCL with a targeted therapy combination before chemotherapy. RLI produced a high ORR, and RLI with chemotherapy resulted in durable responses. This establishes the potential for developing biologically driven and noncytotoxic first-line therapies for DLBCL.

Peripheral T-cell lymphomas (PTCLs) are a heterogeneous group of aggressive non-Hodgkin lymphomas, the majority of which have high relapse rates following standard therapy. Despite use of consolidative stem cell transplant (SCT) following frontline therapy, there remains no consensus on its utility. The double-blind randomized phase 3 ECHELON-2 study (#NCT01777152; clinicaltrials.gov) demonstrated improved progression-free survival (PFS) and overall survival with frontline brentuximab vedotin plus cyclophosphamide, doxorubicin, and prednisone (A+CHP). Herein, we conducted an exploratory subgroups analysis of the impact of consolidative SCT on PFS in patients with previously untreated CD30+ PTCL (ALK- anaplastic large cell lymphoma [ALCL] and non-ALCL) who were in complete response (CR) after frontline treatment with A+CHP or cyclophosphamide, doxorubicin, vincristine, and prednisone. Median PFS follow-up was 47.57 months. The PFS hazard ratio was 0.36, equating to a 64% reduction in the risk of a PFS event in patients who underwent SCT. The median PFS in patients who underwent SCT was not reached, vs 55.66 months in patients who did not undergo SCT. PFS results favored the use of SCT in both ALK- ALCL and non-ALCL subgroups. These data support the consideration of consolidative SCT in patients with CD30+PTCL who achieve CR following treatment with A+CHP.

Peripheral T-cell lymphomas (PTCL) are a unique subset of lymphomas with a poor prognosis due to limited treatment options. We performed a phase 1 study of carfilzomib in patients with relapsed/refractory PTCL to determine the safety profile and the maximum tolerated dose (MTD) of this agent. The study was a classical 3 + 3 phase 1 design with intra-patient dose escalation allowed beginning on day 8 of cycle 1 and subsequently. Dose-limiting toxicity (DLT) was defined as the occurrence of any grade 3/4 adverse event. Carfilzomib was given on days 1, 2, 8, 9, 15, and 16 of a 28-day cycle. Fifteen patients were enrolled from 3 centers. The median age of patients was 62. The median number of prior therapies for subjects on this trial was five. The MTD of carfilzomib was 36 mg/m2. Dose-limiting toxicities included anemia and sepsis. Serious adverse events were seen in 45% of patients. Single-agent carfilzomib leads to a complete response in one patient and a partial response in one patient. Overall, the drug was reasonably tolerated for a heavily pretreated population, but the limited response rate and short duration of response demonstrate a lack of promise for carfilzomib as a single agent in this patient population.

BACKGROUND: Despite advances in the treatment of Hodgkin lymphoma with the introduction of PET-adapted regimens, practical challenges prevent more widespread use of these approaches. The ECHELON-1 study assessed the safety and efficacy of front-line A+AVD (brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine) versus ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) in patients with stage III or IV classical Hodgkin lymphoma. The primary analysis showed improved modified progression-free survival with A+AVD. We present an updated analysis of ECHELON-1 at 5 years, an important landmark for this patient population. METHODS: ECHELON-1 was an international, open-label, randomised, phase 3 trial done at 218 clinical sites, including hospitals, cancer centres, and community clinics, in 21 countries. Previously untreated patients (≥18 years with an Eastern Cooperative Oncology Group performance status of ≤2) with stage III or IV classical Hodgkin lymphoma were randomly assigned (1:1) to receive A+AVD (brentuximab vedotin, 1·2 mg/kg of bodyweight, doxorubicin 25 mg/m2 of body surface area, vinblastine 6 mg/m2, and dacarbazine 375 mg/m2) or ABVD (doxorubicin 25 mg/m2, bleomycin 10 U/m2, vinblastine 6 mg/m2, and dacarbazine 375 mg/m2) intravenously on days 1 and 15 of each 28-day cycle for up to six cycles. Stratification factors included region (Americas vs Europe vs Asia) and International Prognostic Score risk group (low, intermediate, or high risk). The primary endpoint was modified progression-free survival; this 5-year update includes analysis of progression-free survival as per investigator assessment in the intention-to-treat population, which was an exploratory endpoint, although the 5-year analysis was not prespecified in the protocol. This trial is registered with ClinicalTrials.gov (NCT01712490) and EudraCT (2011-005450-60), and is ongoing. FINDINGS: Between Nov 19, 2012, and Jan 13, 2016, 1334 patients were randomly assigned to receive A+AVD (n=664) or ABVD (n=670). At a median follow-up of 60·9 months (IQR 52·2-67·3), 5-year progression-free survival was 82·2% (95% CI 79·0-85·0) with A+AVD and 75·3% (71·7-78·5) with ABVD (hazard ratio [HR] 0·68 [95% CI 0·53-0·87]; p=0·0017). Among PET-2-negative patients, 5-year progression-free survival was higher with A+AVD than with ABVD (84·9% [95% CI 81·7-87·6] vs 78·9% [75·2-82·1]; HR 0·66 [95% CI 0·50-0·88]; p=0·0035). 5-year progression-free survival for PET-2-positive patients was 60·6% (95% CI 45·0-73·1) with A+AVD versus 45·9% (32·7-58·2) with ABVD (HR 0·70 [95% CI 0·39-1·26]; p=0·23). Peripheral neuropathy continued to improve or resolve over time with both A+AVD (375 [85%] of 443 patients) and ABVD (245 [86%] of 286 patients); more patients had ongoing peripheral neuropathy in the A+AVD group (127 [19%] of 662) than in the ABVD group (59 [9%] of 659). Fewer secondary malignancies were reported with A+AVD (19 [3%] of 662) than with ABVD (29 [4%] of 659). More livebirths were reported in the A+AVD group (n=75) than in the ABVD group (n=50). INTERPRETATION: With 5 years of follow-up, A+AVD showed robust and durable improvement in progression-free survival versus ABVD, regardless of PET-2 status, and a consistent safety profile. On the basis of these findings, A+AVD should be preferred over ABVD for patients with previously untreated stage III or IV classical Hodgkin lymphoma.

R-FND (rituximab, fludarabine, mitoxantrone, and dexamethasone) can induce molecular remissions in indolent lymphoma. The addition of 90yttrium ibritumomab tiuxetan (90YIT) radioimmunotherapy following first-line induction treatment in patients with advanced follicular lymphoma (FL) may improve remission rates. We now report 10-year follow-up results from our sequential treatment approach with an abbreviated regimen of R-FND followed by 90YIT consolidation and rituximab maintenance. Forty-nine patients were enrolled; 47 received treatment. Patients had high-risk (FLIPI score ≥3) FL of grade 1-3A and stage III/IV with adequate hematologic function. Following R-FND, the complete and partial response rates were 91% and 8.5%, respectively. After 90YIT consolidation, the CR rate increased to 97%. The 10-year PFS rate was 49%. The most common non-hematologic, grade 3 or 4 adverse events were fatigue, dyspnea, and myalgia. Five developed myelodysplastic syndrome (MDS). This treatment approach is most appropriate in FLIPI-based high-risk patients whose outlook with standard therapy is inadequate.

PURPOSE: Preclinical and early clinical data suggested that combining histone deacetylase (HDAC) and mTOR inhibitors can synergistically inhibit Hodgkin lymphoma. PATIENTS AND METHODS: During the dose-escalation study (ClinicalTrials.gov number: NCT01087554) with the HDAC inhibitor vorinostat and the mTOR inhibitor sirolimus (V+S), a patient with Hodgkin lymphoma refractory to nine prior therapies demonstrated a partial response (PR) lasting for 18.5 months, which promoted additional enrollment of patients with Hodgkin lymphoma as well as exploration of an alternative combination of vorinostat and mTOR inhibitor everolimus (V+E). RESULTS: A total of 40 patients with refractory Hodgkin lymphoma received V+S (n = 22) or V+E (n = 18). Patients received a median of five prior therapies, including brentuximab (n = 39), autologous stem cell transplantation (n = 26), and allogeneic stem cell transplantation (n = 12). The most frequent grade ≥3 treatment-related adverse event was thrombocytopenia in 55% and 67% of patients treated with V+S and V+E, respectively. Complete response was reported in 6 (27%) patients treated with V+S and 2 (11%) patients treated with V+E, and PR was reported in 6 patients (27%) treated with V+S and 4 (22%) patients treated with V+E (objective response rate of 55% and 33%, respectively). In summary, combined HDAC and mTOR inhibition had encouraging activity in heavily pretreated patients with relapsed/refractory Hodgkin lymphoma and warrants further investigation. CONCLUSIONS: Combined HDAC and mTOR inhibition has salutary activity in patients with relapsed refractory Hodgkin lymphoma and warrants further investigation.

PURPOSE: Burkitt lymphoma is an aggressive B-cell lymphoma curable with dose-intensive chemotherapy derived from pediatric leukemia regimens. Treatment is acutely toxic with late sequelae. We hypothesized that dose-adjusted etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, and rituximab (DA-EPOCH-R) may obviate the need for highly dose-intensive chemotherapy in adults with Burkitt lymphoma. METHODS: We conducted a multicenter risk-adapted study of DA-EPOCH-R in untreated adult Burkitt lymphoma. Low-risk patients received three cycles without CNS prophylaxis, and high-risk patients received six cycles with intrathecal CNS prophylaxis or extended intrathecal treatment if leptomeninges were involved. The primary endpoint was event-free survival (EFS), and secondary endpoints were toxicity and predictors of EFS and overall survival (OS). RESULTS: Between 2010 and 2017, 113 patients were enrolled across 22 centers, and 98 (87%) were high risk. The median age was 49 (range, 18-86) years, and 62% were ≥ 40 years. Bone marrow and/or CSF was involved in 29 (26%) of patients, and 28 (25%) were HIV positive. At a median follow-up of 58.7 months, EFS and OS were 84.5% and 87.0%, respectively, and EFS was 100% and 82.1% in low- and high-risk patients. Therapy was equally effective across age groups, HIV status, and International Prognostic Index risk groups. Involvement of the CSF identified the group at greatest risk for early toxicity-related death or treatment failure. Five treatment-related deaths (4%) occurred during therapy. Febrile neutropenia occurred in 16% of cycles, and tumor lysis syndrome was rare. CONCLUSION: Risk-adapted DA-EPOCH-R therapy is effective in adult Burkitt lymphoma regardless of age or HIV status and was well tolerated. Improved therapeutic strategies for adults with CSF involvement are needed (funded by the National Cancer Institute; ClinicalTrials.gov identifier: NCT01092182).

OBJECTIVES: To evaluate the cost-effectiveness of brentuximab vedotin (Adcetris) in combination with cyclophosphamide, doxorubicin, and prednisone (A+CHP) in the first-line setting for CD30-expressing peripheral T-cell lymphoma (PTCL). STUDY DESIGN: An economic model was developed using clinical and quality-of-life (QOL) data from the ECHELON-2 trial, in which A+CHP demonstrated significant improvement in progression-free survival (PFS) and overall survival (OS) versus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). METHODS: A partitioned survival model, consisting of 3 health states (PFS, postprogression survival, and death), was constructed from a US payer perspective over a lifetime time horizon. PFS and OS observed from ECHELON-2 were extrapolated using standard parametric distributions. The best-fitting distributions (log-normal for both arms) were selected based on statistical goodness of fit and clinical plausibility of the long-term projections. Utilities were based on the European Quality of Life 5-Dimensional data collected in ECHELON-2. Medical resource use and costs were from literature and standard sources. RESULTS: The model predicted that A+CHP extended PFS and OS by 2.92 and 3.38 years, respectively, over CHOP. After incorporating QOL and discounting, A+CHP was associated with 1.79 quality-adjusted life-years gained at a total incremental cost of $159,388, resulting in an incremental cost-effectiveness ratio (ICER) of $89,217. Sensitivity analyses provided ICERs ranging approximately from $57,000 to $138,000. The estimated probability that A+CHP is cost-effective compared with CHOP was 82% at a willingness-to-pay threshold of $150,000. CONCLUSIONS: Based on the ECHELON-2 trial data, this analysis found A+CHP to be cost-effective for patients with previously untreated CD30-expressing PTCL.
