The magnitude and sustainability of treatment benefit of zuranolone on function and well-being as assessed by the SF-36 in adult patients with MDD and PPD: An integrated analysis of 4 randomized clinical trials.

BACKGROUND: Major depressive disorder (MDD) and postpartum depression (PPD) are disabling conditions. This integrated analysis of MDD and PPD clinical trials investigated the impact of zuranolone-a positive allosteric modulator of synaptic and extrasynaptic GABAA receptors and neuroactive steroid under investigation for adults with MDD and approved as an oral, once-daily, 14-day treatment course for adults with PPD in the US-on health-related quality of life, including functioning and well-being, as assessed using the 36-item Short Form Health Survey V2 (SF-36). METHODS: Integrated data from 3 MDD (201B, MOUNTAIN, WATERFALL) and 1 PPD trial (ROBIN) for individual SF-36 domains were compared for zuranolone (30- and 50-mg) vs placebo at Day (D)15 and D42. Comparisons between zuranolone responders (≥50 % reduction from baseline in 17-item Hamilton Depression Rating Scale total score) and nonresponders were assessed. RESULTS: Overall, 1003 patients were included (zuranolone, n = 504; placebo, n = 499). Significant differences in change from baseline (CFB) to D15 for patients in zuranolone vs placebo groups were observed in 6/8 domains; changes were sustained or improved at D42, with significant CFB differences for all 8 domains. Zuranolone responders had significantly higher CFB scores vs nonresponders for all domains at D15 and D42 (p < 0.001). LIMITATIONS: Two zuranolone doses were integrated across populations of 2 disease states with potential differences in functioning, comorbidities, and patient demographics. All p-values presented are nominal. CONCLUSIONS: Integrated data across 4 zuranolone clinical trials showed improvements in functioning and well-being across all SF-36 domains. Benefits persisted after completion of treatment course at D42.

Effect of Zuranolone on Concurrent Anxiety and Insomnia Symptoms in Women With Postpartum Depression.

Objective: Concurrent anxiety and/or insomnia symptoms in women with postpartum depression (PPD) are common and associated with more severe PPD. The effects of zuranolone on concurrent anxiety and/or insomnia symptoms and on patient-perceived functional health in women with PPD in the ROBIN study are reported.Methods: The phase 3, double-blind, randomized, placebo-controlled trial (conducted January 2017-December 2018) included women aged 18-45 years, ≤ 6 months postpartum, with PPD (onset of DSM-5-defined major depressive episode in the third trimester or ≤ 4 weeks postpartum) and baseline 17-item Hamilton Depression Rating Scale (HDRS-17) total score ≥ 26. Women were randomized 1:1 to once-daily oral zuranolone 30 mg (n = 77) or placebo (n = 76) for 14 days with follow-up through day 45. Concurrent remission of depressive and anxiety symptoms (Hamilton Anxiety Rating Scale total score ≤ 7 plus HDRS-17 total score ≤ 7 or Montgomery-Asberg Depression Rating Scale total score ≤ 10), improvement in insomnia symptoms, patient-perceived functional health, and treatment effect sizes described by number needed to treat (NNT) were assessed. Analyses were exploratory; P values are nominal.Results: Rates of concurrent remission of depressive and anxiety symptoms were higher with zuranolone versus placebo (P < .05) at days 3, 15, and 45; the rate of sustained concurrent remission (ie, at both days 15 and 45) was also higher with zuranolone (P < .05). Anxiety symptoms (assessed by HDRS-17 anxiety/somatization subscale and Edinburgh Postnatal Depression Scale anxiety subscale) improved with zuranolone versus placebo (P < .05) at days 3 through 45. Potential benefits on insomnia symptoms and patient-perceived functional health were observed. Day 15 NNTs were 5 for both HDRS-17 response and remission.Conclusions: Zuranolone was associated with concurrent improvements in depressive and anxiety symptoms, with beneficial effects on insomnia symptoms and patient-perceived functional health in adults with PPD.Trial Registration: ClinicalTrials.gov identifier: NCT02978326.

Patient-reported health-related quality of life from a randomized, placebo-controlled phase 2 trial of zuranolone in adults with major depressive disorder.

BACKGROUND: Major depressive disorder (MDD), a disabling, potentially life-threatening condition, negatively affects health-related quality of life (HRQoL). This secondary analysis aimed to understand the impact of the neuroactive steroid zuranolone on HRQoL using the Short Form-36v2 Health Survey (SF-36v2). METHODS: Adult patients with MDD and 17-item Hamilton Rating Scale for Depression total score ≥22 were randomized 1:1 to receive zuranolone 30 mg or placebo for 2 weeks, with 4 weeks follow-up. SF-36v2 scores were assessed at Day 15 across 8 domains (Physical Functioning, Role Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional, and Mental Health) and 2 summary scores (Physical and Mental Component), using a mixed-effects model for repeated measures. Correlations between SF-36v2 scores and clinician-reported efficacy endpoints were assessed using Pearson's correlation. RESULTS: Eighty-nine patients were treated with zuranolone 30 mg (n = 45) or placebo (n = 44). In zuranolone-treated patients, HRQoL improved across all SF-36v2 domains and summary scores at Day 15. Improvements exceeding established minimally important difference thresholds were observed in Bodily Pain, General Health, Vitality, Social Functioning, Role Emotional, and Mental Health scores. Improvements in General Health, Vitality, Mental Health, and Mental Component Summary were statistically significant versus placebo (p ≤ 0.025). Clinician-rated endpoints negatively correlated with SF-36v2 scores. LIMITATIONS: The small unipolar depression sample may not be representative of all US MDD patients. HRQoL measures could be impacted by factors unrelated to depression. CONCLUSIONS: Zuranolone-treated patients reported rapid and significant improvements in HRQoL versus placebo at Day 15. HRQoL improvements correlated with improvements in clinician-rated assessments. TRIAL REGISTRATION: clinicaltrials.gov:NCT03000530; https://clinicaltrials.gov/ct2/show/NCT03000530.

Achieving clinical response in postpartum depression leads to improvement in health-related quality of life.

OBJECTIVE: To evaluate the health-related quality of life (HRQoL) burden associated with postpartum depression (PPD), determine the extent to which clinical response impacts HRQoL, and estimate the impact of PPD and clinical response on healthcare resource utilization (HRU) and productivity. METHODS: Patient data (n = 127) from two multicenter, randomized, double-blind, placebo-controlled phase 3 clinical trials evaluating the safety and efficacy of brexanolone injection in adults with PPD were employed for these posthoc analyses. HRQoL and health utility was assessed with the SF-36-v2 Health Survey (SF-36v2) acute version. The 17-item Hamilton Rating Scale for Depression (HAMD-17) total score was used to identify clinical response (≥50% reduction in HAMD-17 total score). Baseline HRQoL burden was assessed by comparison to age- and gender-adjusted population normative data from the 2009 QualityMetric PRO Norming study. The impact of clinical response was evaluated by comparing day 7 and day 30 SF-36v2 scores between clinical responders and non-responders. Interpretations of the meaningfulness of clinical response were indirectly estimated via 2017 National Health and Wellness Survey data linking SF-36v2 mental component summary (MCS) scores to (HRU) and productivity. RESULTS: Baseline HRQoL of patients with PPD was significantly below normative values. Day 7 and day 30 clinical response were associated with large and statistically significant improvements in HRQoL, greater likelihood of meeting SF-36v2 responder definitions, and reduced impairment. MCS levels corresponding to those observed in clinical responders were linked to lower HRU and productivity loss relative to non-responders. CONCLUSIONS: PPD places a substantial burden on HRQoL. Achievement of rapid clinical response (at day 7) and clinical response sustained several weeks following the end of treatment (day 30) led to significant improvement in HRQoL, suggesting the importance of identifying women with PPD and providing effective treatment options.

Number Needed to Treat and Number Needed to Harm analysis of the zuranolone phase 2 clinical trial results in major depressive disorder.

BACKGROUND: Zuranolone (SAGE-217) is a novel, investigational positive allosteric modulator of GABAA receptors being investigated in major depressive disorder (MDD). This analysis of phase 2 data quantified the benefit and risk of zuranolone (30mg) versus placebo and antidepressants in terms of number needed to treat (NNT) and number needed to harm (NNH). METHODS: Rates of response, remission, and all-cause discontinuation for zuranolone and 11 antidepressant comparators were obtained from the zuranolone phase 2 clinical study (N=89) and a published network meta-analysis, respectively. An indirect treatment comparison was conducted using the Bucher method to compare zuranolone to standard-of-care. RESULTS: Zuranolone demonstrated greater benefit compared to placebo on Day 3 (NNT range for response=4-5, NNT for remission=10) and at Day 15 (NNT=3 for response and remission). Compared to SSRIs and SNRIs, zuranolone at Day 15 showed improved treatment response (NNT=4 [95% CI = 3; 16] and 5 [95% CI = 3; 25], respectively) and remission (NNT=4 [95% CI = 2; 13] and 4 [95% CI = 2; 18], respectively). This was accompanied by a reduction in all-cause discontinuation, with negative NNH values (-57 and -28), respectively. LIMITATIONS: Variations in study design across the included trials may limit the generalizability of results. CONCLUSIONS: With a small positive NNT as early as Day 3 indicating robust benefit and a negative NNH indicating reduced harm, this analysis based on a phase 2 study suggests that patients with MDD may benefit from the benefit-to-risk profile of zuranolone.

Brexanolone in Postpartum Depression: Post Hoc Analyses to Help Inform Clinical Decision-Making.

Background: Brexanolone (BRX) injection was approved by the United States Food and Drug Administration in 2019 for the treatment of adults with postpartum depression (PPD) based on two Phase 3 clinical trials. Materials and Methods: Data from the three trials were combined. PPD-specific 17-item Hamilton Rating Scale for Depression (HAMD-17) group-level minimal important difference (MID) and patient-level meaningful change (meaningful change threshold [MCT]) were estimated and applied to differences in BRX versus placebo (PBO) at hour 60 (primary endpoint) and day 30 (end of trial follow-up). Likelihood of HAMD-17 response and remission and Clinical Global Impression of Improvement (CGI-I) response for BRX versus PBO were assessed at hour 60 and as sustained through day 30 using relative risk. Associated number needed to treat (NNT) and number needed to harm (NNH) values were also estimated. Results: Two-hundred nine patients were included. The average HAMD-17 MID estimate was -2.1; the least-squared mean difference between BRX and PBO exceeded this at hour 60 and day 30. Minimal, moderate, and large MCTs were estimated to be -9, -15, and -20 points, respectively. Significantly more BRX-treated than PBO-treated patients achieved minimal, moderate, and large change (all ps < 0.05) at hour 60 and large meaningful response at day 30 (p < 0.05). BRX-treated patients were more likely to sustain HAMD-17 remission and CGI-I response through day 30 versus PBO. NNTs ranged from 4 to 8, with NNH of 97. Conclusions: BRX provided meaningful changes relative to PBO, rapid (hour 60), and sustained improvements (day 30) in PPD symptoms, low NNT, and large NNH. These results may help inform treatment decision-making. Clinicaltrials.gov registration numbers: NCT02614547, NCT02942004, and NCT02942017.

Associations between commonly used patient-reported outcome tools in postpartum depression clinical practice and the Hamilton Rating Scale for Depression.

The objective of this study is to explore the associations between the patient-reported Edinburgh Postnatal Depression Scale (EPDS) and Patient Health Questionnaire (PHQ)-9 and clinician-reported 17-item Hamilton Depression Rating Scale (HAMD-17) in order to facilitate clinical decision-making. An integrated efficacy dataset of three randomized placebo-controlled trials (NCT02614547, NCT02942004, and NCT02942017) evaluating brexanolone injection, a neuroactive steroid chemically identical to allopregnanolone, in women with postpartum depression was used for this post hoc analysis. Data were pooled across treatment arms. Associations were assessed at day 30 (end-of-trial follow-up). Pearson correlation assessed the relationship between EPDS and PHQ-9 item and total scores and HAMD-17 total score. Cohen's kappa assessed agreement of EPDS remission (score < 10) and PHQ-9 remission (score < 5) with HAMD-17 remission (score ≤ 7). Ordinary least squares (OLS) regression models were used to develop equations estimating HAMD-17 total scores from EPDS and PHQ-9 scores, respectively. The total scores showed large correlations (HAMD-17/EPDS: r = 0.71, p < 0.001; HAMD-17/PHQ-9: r = 0.75, p < 0.001). Individual EPDS and PHQ-9 items significantly correlated (r= 0.35 to 0.67, all p < 0.001) with HAMD-17 total score. EPDS had 79% sensitivity and 67% specificity to detect HAMD-17 remission; corresponding estimates for PHQ-9 were 76% and 78%. OLS models yielded the following equations: HAMD-17 total = 2.66 + (EPDS total × 0.87) and HAMD-17 total = 3.99 + (PHQ-9 total × 0.97). There were large and statistically significant associations between patient-reported outcomes (EPDS, PHQ-9) and clinician-reported outcomes (HAMD-17) as clinical improvements were associated with patient-reported symptom improvement. These results provide tools to help translate clinical trial data to clinical practice, thus aiding shared decision-making for this critical population.

Burden and epidemiology of status epilepticus in infants, children, and adolescents: A population-based study on German health insurance data.

OBJECTIVE: Status epilepticus (SE) is an important medical emergency condition with particularly unfavorable outcome in refractory and superrefractory SE (SRSE). The economic impact of SE and especially of SRSE in the pediatric population remains unclear. We aimed to determine the burden of illness of SE in a pediatric patient population. METHODS: Insurance records for patients aged 0-18 years admitted between 2008 and 2015 were selected from a nationwide insurance research database utilizing International Classification of Diseases and Related Health Problems, 10th Revision (ICD-10) codes for SE (G41), epilepsy (G40), or febrile convulsions (R56). Patients were further classified based on admission to the intensive care unit and use of mechanical ventilation. RESULTS: The algorithm identified 11 693 seizure-related admissions and classified 4% as SE. Of these cases, 282 (60.4%) were classified by the algorithm as nonrefractory SE (NRSE), 125 (26.8%) as refractory SE (RSE), and 60 (12.8%) as SRSE. The crude SE incidence was 17.6/100 000, with NRSE being 11.4/100 000, RSE 3.9/100 000, and SRSE 2.3/100 000. SRSE incidence peaked in the 0- to 1-year-old age subgroup accounting for 48.3% of all pediatric SRSE admissions. The median length of stay (LOS) for all SE cases was 7 days, with median 44.5 days in SRSE, 5 days in NRSE, and 12 days in RSE. Mean admission costs for total SE were €15 880, with a mean expense for SRSE of €75 358, for NRSE of €4119, and for RSE of €13 864. The mean LOS for non-SE epilepsy admissions was 3 days, with mean costs of €2697 for epilepsy and €1614 for febrile convulsion admissions. There were no deaths in non-SE and NRSE admissions, whereas the overall mortality for SE was 3%, with 5.6% in RSE and 11.7% in SRSE. SIGNIFICANCE: Although cases classified as SE represented 4% of the seizure-associated admissions, they accounted for 22% of the overall costs. These costs were disproportionately represented by SRSE cases, which accounted for 62% of all SE-associated costs.

Brentuximab vedotin consolidation post-autologous stem cell transplant in Hodgkin lymphoma patients at risk of residual disease: number needed to treat.

The number needed to treat (NNT) with brentuximab vedotin consolidation therapy post-autologous stem cell transplant (ASCT) versus placebo in the phase 3 AETHERA trial to avoid one additional event of disease progression/death was evaluated. AETHERA included 329 Hodgkin lymphoma patients at increased risk of progression post-ASCT who received brentuximab vedotin 1.8 mg/kg (n = 165) or placebo (n = 164) on day 1 of each 21-d cycle (up to 16 cycles). Over 60 months, the NNT with brentuximab vedotin ranged from 4.08 to 7.79 for the intent-to-treat population, 3.18-6.07 for patients with ≥2 risk factors, and 2.98-5.65 for patients with ≥3 risk factors. At various time points, and dependent on the risk group, 3-8 patients would need to be treated with brentuximab vedotin consolidation therapy to prevent a disease progression/death, compared with placebo. Patients with increased risk of relapse may benefit most from brentuximab vedotin.

Costs, length of stay, and mortality of super-refractory status epilepticus: A population-based study from Germany.

OBJECTIVE: Super-refractory status epilepticus (SRSE) is a severe condition in which a patient in status epilepticus (SE) for ≥24 h does not respond to first-, second-, or third-line therapy. The economic impact of SRSE treatment remains unclear. A health insurance research database was used for a population-based estimation of SRSE-associated inpatient costs, length of stay, and mortality in Germany. METHODS: An algorithm using International Classification of Diseases, 10th Edition coding and treatment parameters identified and classified patients in a German statutory health insurance database covering admissions from 2008 to 2013 as having refractory SE (RSE) or SRSE. Admissions data in our study refer to these classifications. Associated patient data included costs, procedures, and demographics. RESULTS: The algorithm identified 2,585 (all type) SE admissions, classified as 1,655 nonrefractory SE (64%), 592 (22.9%) RSE, and 338 (13.1%) SRSE, producing database incidence rates of 15.0 in 100,000, 5.2 in 100,000, and 3.0 in 100,000 per year, respectively. Median cost per admission was €4,063 for nonrefractory SE, €4,581 (p < 0.001) for RSE, and €32,706 (p < 0.001) for SRSE. Median length of stay varied significantly between 8 days (mean = 13.6) in nonrefractory SE, 14 days in RSE, and up to 37 days in SRSE. Discharge mortality increased from 9.6% in nonrefractory SE to 15.0% (p < 0.001) in RSE and 39.9% (p < 0.001) in SRSE. SIGNIFICANCE: This study evaluated the hospital treatment costs associated with admissions classified by the algorithm as SRSE in Germany. SRSE represented 13% of all SE admissions, but resulted in 56% of all SE-related costs. The lack of approved treatments and limited number of evidence-based treatment guidelines highlight the need for further evaluations of the SRSE burden of illness and the potential for further optimization of treatments for SRSE.

A Cost-effectiveness Analysis of Brentuximab Vedotin in Relapsed or Refractory Systemic Anaplastic Large Cell Lymphoma.

Objective: To evaluate the cost-effectiveness of brentuximab vedotin in patients with R/R sALCL from a UK NHS perspective. Methods: A partitioned survival model used clinical outcomes for brentuximab vedotin from the pivotal phase-2 single-arm trial of brentuximab vedotin in 58 patients with R/R sALCL (SG035-0004; NCT00866047), over a lifetime (30-year) time horizon. Comparison with conventional chemotherapy was based on data from the Canadian British Columbia Cancer Agency registry from 40 patients starting salvage chemotherapy after front-line treatment between 1980 and 2012. Survival was extrapolated using parametric distributions, with brentuximab vedotin risk after the trial period assumed equal to conventional chemotherapy. Other modelling assumptions were based on a systematic literature review and clinical expert opinion. Results: Based on statistical extrapolation, brentuximab vedotin was associated with 3.1 years longer duration in the progression-free survival health state and an overall survival improvement of 5.4 years, prior to discounting. In addition, brentuximab vedotin was associated with 2.5 quality-adjusted life years (QALYs) gained at a total incremental cost of £88 556, resulting in an incremental cost-effectiveness ratio (ICER) of approximately £35 400. Sensitivity analyses of alternative model assumptions provided ICERs ranging from approximately £28 100 to £61 900. Comparing only first-line salvage patients reduced the ICER to £26 800 per QALY gained. Conversely, considering only patients with Eastern Corporative Oncology Group performance status of 0 or 1 increased the ICER to approximately £38 200. At a willingness-to-pay threshold of £50 000, the estimated probability that brentuximab vedotin is cost-effective compared with conventional chemotherapy was 86.5%. Conclusion: Compared to conventional chemotherapy, and considering the full survival period, brentuximab vedotin may provide a valuable treatment choice for patients with R/R sALCL, a population with limited therapeutic options.

Brentuximab vedotin in relapsed/refractory Hodgkin lymphoma post-autologous stem cell transplant: a cost-effectiveness analysis in Scotland.

OBJECTIVE: To evaluate cost-effectiveness of brentuximab vedotin in patients with relapsed/refractory Hodgkin lymphoma who have received autologous stem cell transplantation, from a Scottish healthcare payer perspective. METHODS: A Microsoft Excel-based partitioned survival model comprising three health states (progression-free survival [PFS], post-progression survival, and death) was developed. Relevant comparators were chemotherapy with or without radiotherapy (C/R) and C/R with intent to allogeneic hematopoietic stem cell transplantation (alloSCT). Data were obtained from the pivotal phase II single-arm trial in 102 patients (SG035-0003; NCT00848926), a systematic literature review and clinical expert opinions (where empirical evidence was unavailable). PFS and overall survival for brentuximab vedotin were estimated using 5-year follow-up data from SG035-0003, and extrapolated using event rates observed for comparator treatments from published survival data. Resource use included drug acquisition and administration; alloSCT; treatment of adverse events; and long-term follow-up. Deterministic and probabilistic sensitivity analyses were conducted to evaluate the impact of uncertainty. RESULTS: In the base case, the incremental cost-effectiveness ratio (ICER) for brentuximab vedotin was £38,769 per quality-adjusted life year (QALY) vs C/R, whereas C/R with intent to alloSCT was dominated by brentuximab vedotin. ICERs for brentuximab vedotin generated by the deterministic sensitivity analysis ranged between £32,000-£54,000 per QALY. Including productivity benefits reduced the ICER to £28,881 per QALY. LIMITATIONS: Limitations include lack of comparative data from this single arm study and the heterogeneous population. Inconsistent baseline characteristic reporting across studies prevented complete assessment of heterogeneity and the extent of potential bias in clinical and cost-effectiveness estimates. CONCLUSIONS: Although the base case ICER is above the threshold usually applied in Scotland, it is relatively low compared with other orphan drugs, and lower than the ICER generated using a previous data cut of SG035-0003 that informed a positive recommendation from the Scottish Medicines Consortium, under its decision-making framework for assessment of ultra-orphan medicines.

An Evaluation of Treatment Patterns and Outcomes in Elderly Patients Newly Diagnosed With Acute Myeloid Leukemia: A Retrospective Analysis of Electronic Medical Records From US Community Oncology Practices.

BACKGROUND: Many elderly patients with acute myeloid leukemia (AML) are considered ineligible for standard intensive induction therapy due to performance status and comorbidities. We analyzed treatment patterns and outcomes among elderly patients newly diagnosed with AML in the US community oncology setting. METHODS: A retrospective observational study was conducted using patient-level data from a network of US community oncology practices provided by Altos Solutions. Patients aged ≥ 60 years, diagnosed with AML between November 2005 and February 2014, with ≥ 1 recorded visit and ≥ 6 months between diagnosis and data cutoff, were included. Only patients who received active treatment or best supportive care (BSC) per National Comprehensive Cancer Network (NCCN) AML Guidelines were analyzed. RESULTS: Of 1139 patients meeting the inclusion criteria, 922 (median age 76 years) received NCCN-recommended treatments: standard induction (n = 5), low-intensity therapy (n = 425), BSC with hydroxyurea (HU) (n = 36), or BSC without HU (n = 455). For the low-intensity therapy cohort, median time from diagnosis to treatment initiation was 17 days; median duration of therapy was 5.1 months. Median overall survival (OS) from diagnosis in the low-intensity, BSC with HU, and BSC without HU groups was 12.3, 7.0, and 49.4 months, respectively. Median time to next therapy/death was 10.1 months in patients receiving low-intensity therapy. A higher proportion of patients receiving low-intensity therapy required transfusion or other supportive care versus those receiving BSC. CONCLUSIONS: As expected, OS in patients receiving low-intensity therapy or BSC with HU is poor for elderly patients with AML. Remarkably, intensive induction strategies are rarely used for older patients in community oncology practice.

Quality of life results from a phase 3 study of brentuximab vedotin consolidation following autologous haematopoietic stem cell transplant for persons with Hodgkin lymphoma.

Brentuximab vedotin (BV) significantly improved progression-free survival in a phase 3 study in patients with relapsed or refractory Hodgkin lymphoma (RR-HL) post-autologous-haematopoietic stem cell transplant (auto-HSCT); we report the impact of BV on quality of life (QOL) from this trial. The European Quality of Life five dimensions questionnaire was administered at the beginning of each cycle, end of treatment, and every 3 months during follow-up; index value scores were calculated using the time trade-off (TTO) method for UK-weighted value sets. Questionnaire adherence during the trial was 87·5% (N = 329). In an intent-to-treat analysis, compared with placebo, TTO scores in the BV arm did not exceed the minimally important difference (MID) of 0·08 except at month 15 (-0·084; 95% confidence interval, -0·143 to -0·025). On-treatment index scores were similar between arms and did not reach the MID at any time point; mixed-effect modelling showed that BV treatment effect was not significant (P = 0·2127). BV-associated peripheral neuropathy did not meaningfully impact QOL. Utility scores for patients who progressed declined compared with those who did not; TTO scores between these patients exceeded the MID beginning at month 15. In conclusion, QOL decreased modestly with BV consolidation treatment in patients with RR-HL at high risk of relapse after auto-HSCT.

Clinical and economic burden of peripheral T-cell lymphoma in commercially insured patients in the United States: findings using real-world claims data.

OBJECTIVE: This retrospective cohort study utilized real-world claims data to assess the clinical and economic burden of peripheral T-cell lymphoma (PTCL) over the continuum of care in the US. METHODS: Data were extracted from US administrative claims databases to identify adult patients with PTCL (ICD-9-CM code 202.7X) diagnosed between October 2007 and June 2011. Patients had to have ≥6 months of continuous enrollment before and ≥12 months of continuous enrollment after their index date (date of first PTCL diagnosis). PTCL patients were matched (1:5) by age, sex, region, plan type, payer type, and length of continuous enrollment, to a control group of randomly selected patients without PTCL. Patient-level healthcare resource utilization data and associated costs (in US dollars) were measured. Mean costs per patient per month were determined. RESULTS: Of 2820 patients with PTCL, 1000 met all inclusion criteria (median age = 57 years; 57.5% male) and were matched to the control group (n = 5000). On an average monthly basis, PTCL patients were hospitalized more frequently (0.07 vs 0.01 admissions; p < 0.0001) and had a longer length of hospital stay (6.4 vs 4.0 days; p < 0.0001) compared with controls. PTCL patients also had higher monthly utilization of pharmacy services (2.85 vs 0.97 prescriptions; p < 0.0001), office visits (1.35 vs 0.34 visits; p < 0.0001), ER visits (0.07 vs 0.02 visits; p < 0.0001), hospice stays (0.05 vs 0.01 stays; p < 0.0001) and other patient services/procedures. Overall, PTCL patients incurred higher average monthly costs per patient compared with control patients ($6327.84 vs $388.39; p < 0.0001), driven mainly by hospitalizations (32.2% of overall costs) and pharmacy services (19.6%). CONCLUSIONS: This is the first real-world study to quantify healthcare resource utilization, costly treatment, and overall medical expenditure in commercially insured PTCL patients. Better tolerated and more effective treatments may improve disease management and reduce the clinical and economic burden of PTCL.

Patient-Reported Outcomes Labeling for Products Approved by the Office of Hematology and Oncology Products of the US Food and Drug Administration (2010-2014).

PURPOSE: To review the use of patient-reported outcome (PRO) data in medical product labeling granted by the US Food and Drug Administration (FDA) for new molecular entities and biologic license applications by the FDA Office of Hematology and Oncology Products (OHOP) between January 2010 and December 2014, to elucidate challenges faced by OHOP for approving PRO labeling, and to understand challenges faced by drug manufacturers to include PRO end points in oncology clinical trials. METHODS: FDA Drug Approval Reports by Month were reviewed to obtain the number of new molecular entities and biologic license applications approved from 2010 to 2014. Drugs approved by the FDA OHOP during this period were selected for further review, focusing on brand and generic name; approval date; applicant; indication; PRO labeling describing treatment benefit, measures, end point status, and significant results; FDA reviewer feedback on PRO end points; and study design of registration trials. First in class, priority review, fast track, orphan drug, or accelerated approval status was retrieved for selected oncology drugs from 2011 to 2014. Descriptive analyses were performed by using Microsoft Excel 2010. RESULTS: Of 160 drugs approved by the FDA (2010-2014), 40 were approved by OHOP. Three (7.5%) of the 40 received PRO-related labeling (abiraterone acetate, ruxolitinib phosphate, and crizotinib). Compared with nononcology drugs (2011-2014), oncology drugs were more likely to be orphan and first in class. The majority of oncology drug reviews by FDA were fast track, priority, or accelerated. CONCLUSION: Although symptoms and functional decrements are common among patients with cancer, PRO labeling is rare in the United States, likely because of logistical hurdles and oncology study design. Recent developments within the FDA OHOP to capture PROs in oncology studies for the purpose of product labeling are encouraging.

Panoptic clinical review of the current and future treatment of relapsed/refractory T-cell lymphomas: Peripheral T-cell lymphomas.

Peripheral T-cell lymphomas (PTCLs) tend to be aggressive and chemorefractory, with about 70% of patients developing relapsed/refractory disease. Prior to 2009, chemotherapies were the only options for relapsed/refractory PTCL, other than hematopoietic transplants. However, chemotherapy only improves survival by about 1 month compared with palliation. Four drugs are now approved in the US to treat relapsed/refractory PTCL: pralatrexate, romidepsin, belinostat, and brentuximab vedotin (for systemic anaplastic large cell lymphoma [sALCL]). Response rates with pralatrexate, romidepsin, and belinostat range from 25 to 54% in mixed relapsed/refractory PTCL populations, while 86% of sALCL patients respond to brentuximab vedotin. Here, we critically evaluate the evidence supporting the current drug treatment of relapsed/refractory PTCL, and look to the future to see how the treatment panorama may change with the advent of new targeted therapies, some of which (e.g., alisertib in PTCL and mogamulizumab in CCR4-positive adult T-cell leukemia/lymphoma) are already in phase 3 trials.

Panoptic clinical review of the current and future treatment of relapsed/refractory T-cell lymphomas: Cutaneous T-cell lymphomas.

Primary cutaneous T-cell lymphomas (CTCLs), such as mycosis fungoides and Sézary syndrome, are a rare group of non-Hodgkin lymphomas, usually treated using a multimodal approach. Unfortunately, many patients go on to develop relapsed/refractory disease. Systemic treatment for relapsed/refractory CTCL has historically relied on chemotherapies and interferons, and while active, responses are often short-lived. Three drugs are now approved in the US to treat relapsed/refractory CTCL including the oral retinoid, bexarotene, and histone deacetylase inhibitors, romidepsin and vorinostat. Although response rates are typically <35%, romidepsin and vorinostat can induce some durable responses in heavily pretreated patients and alleviate bothersome symptoms, such as pruritus. New studies indicate that the anti-CD30 antibody-drug conjugate brentuximab vedotin, anti-CCR4 antibody mogamulizumab, and fusion protein immunotoxin A-dmDT390-bisFv(UCHT1) may be particularly active in this setting. In this paper, we present an exhaustive review of the clinical data on current and possible future drug treatment options for relapsed/refractory CTCL.
