RESUMO
OBJECTIVE: To evaluate the severity and frequency of infusion reactions (IR) in patients with highly active relapsing-remitting multiple sclerosis (MS) In Russian population receiving alemtuzumab therapy. MATERIAL AND METHODS: In retrospective study, we analyzed data from 50 patients with highly active relapsing-remitting multiple sclerosis (MS) from six Regional MS Centers in the Russian Federation who received two courses of alemtuzumab between 2018 and 2022. RESULTS: Among all IRs, the most frequently reported were hives-like rashes, which were registered in 27 people, mostly of mild severity (70.6%). Headaches were the second most common IR, observed in 17 patients (34%). When comparing the group of patients who underwent music therapy (MT) with those who received alemtuzumab therapy without MT, no statistically significant difference was found in the frequency and severity of IRs. CONCLUSION: All patients experienced IRs of varying degrees of severity. A decrease in the score on the EDSS disability scale was noted. MT did not affect the occurrence or severity of IRs.

BACKGROUND: Alemtuzumab is effective in reducing relapse rate and disability, but limited data exist on its effect on cognitive function in relapsing multiple sclerosis (RMS). The present study assessed neurocognitive function and safety associated with alemtuzumab treatment in RMS. METHODS: This longitudinal, single-arm, prospective study included people with RMS (aged 25-55 years) who were treated with alemtuzumab in clinical practice in the United States of America and Canada. The first participant was enrolled in December 2016. The primary endpoint was the change from baseline to post-baseline (month [M] 12/24) in MS-COGnitive (MS-COG) composite score. Secondary endpoints included Paced Auditory Serial Addition Test (PASAT), Symbol Digit Modalities Test (SDMT), Brief Visuospatial Memory Test-Revised (BVMT-R), Selective Reminding Test (SRT), Controlled Oral Word Association Test (COWAT), and Automated Neuropsychological Assessment Metrics (ANAM) scores. Depression and fatigue were assessed using Hamilton Rating Scale-Depression (HAM-D) and Fatigue Severity Scale (FSS)/Modified Fatigue Impact Scale (MFIS), respectively. Magnetic resonance imaging (MRI) parameters were assessed when available. Safety was assessed throughout the study. Descriptive statistics were used for the pre-specified statistical analyses. Since the study was terminated early (November 2019) because of operational and resource difficulties, post hoc analyses for statistical inference were performed among participants who had a baseline value and at least one complete post-baseline assessment for cognitive parameters, fatigue, or depression. RESULTS: Of the 112 participants enrolled, 39 were considered as the primary analysis population at M12. At M12, a mean change of 0.25 (95% confidence interval [CI]: 0.04, 0.45; p = 0.0049; effect size [ES]: 0.39) was observed in the MS-COG composite score. Improvements were observed in processing speed (based on PASAT and SDMT; p < 0.0001; ES: 0.62), as well as in individual PASAT, SDMT and COWAT scores. An improvement was also noted in HAM-D (p = 0.0054; ES: -0.44), but not in fatigue scores. Among MRI parameters, decreases in burden of disease volume (BDV; ES: -0.12), new gadolinium-enhancing lesions (ES: -0.41) and newly active lesions (ES: -0.07) were observed at M12. About 92% of participants showed stable or improved cognitive status at M12. There were no new safety signals reported in the study. The most common adverse events (≥10% of participants) were headache, fatigue, nausea, insomnia, urinary tract infection, pain in extremity, chest discomfort, anxiety, dizziness, arthralgia, flushing, and rash. Hypothyroidism (3.7%) was the most frequent adverse event of special interest. CONCLUSION: The findings from this study suggest that alemtuzumab has a positive impact on cognitive function with significant improvements in processing speed and depression in people with RMS over a period of 12 months. The safety profile of alemtuzumab was consistent with previous studies.

AIM: Evaluate the real-world costs over two years and costs by site of care for ocrelizumab (OCR), natalizumab (NTZ), and alemtuzumab (ATZ) in patients with multiple sclerosis (MS). METHODS: This retrospective study used HealthCore Integrated Research Database and included continuously enrolled adults with MS initiating OCR, NTZ, and ATZ between April 2017 and July 2019 (i.e. patient identification period). Annual total cost of care (pharmacy and medical costs) was evaluated for the first- and second-year of follow-up, further stratified by site of care. Costs were measured using health plan allowed amount and adjusted to 2019 US dollars. Sensitivity analyses were conducted in patients who completed yearly dosing schedule according to Food and Drug Administration approved prescribing information. RESULTS: Overall, 1,058, 166, and 46 patients were included in OCR, NTZ, and ATZ cohorts, respectively. Mean (standard deviation [SD]) total cost of care during first- and second-year follow-up were $125,597 ($72,274) and $109,618 ($75,085) for OCR, $117,033 ($57,102) and $106,626 ($54,872) for NTZ, and $179,809 ($97,530) and $108,636 ($77,973) for ATZ. Infusible drug cost was the main driver in all three cohorts accounting for >78% of the total costs. Annual total cost of care increased substantially after patients started/switched to infusible DMTs. Across site of care, hospital outpatient infusion was common (OCR 58%, NTZ 37%, ATZ 49%) and expensive followed by physician office infusion (OCR 28%, NTZ 40%, ATZ 16%); home infusion was the least common (<10%) and least expensive. LIMITATIONS: The results were limited to commercially insured patients (specifically those with Anthem-affiliated health plans). CONCLUSIONS: Real-world costs increased after patients started/switched to infusible DMTs. Drug cost is the main driver for the total costs, which varied substantially by site of care. Controlling drug cost markups and using home setting for infusion can reduce costs in the treatment of MS patients.
Ocrelizumab (OCR), natalizumab (NTZ), and alemtuzumab (ATZ) are infusible drugs to treat patients with multiple sclerosis (MS). We did a study to understand the costs of these infusible MS drugs in real-world settings by analyzing a patients' pharmacy and medical claims database. A total of 1,058 patients were included. We found that the annual total costs increased substantially after patients started to use these infusible MS drugs. Specifically, the average first- and second-year total costs for patients were $125,597 and $109,618 for OCR, $117,033 and $106,626 for NTZ, and $179,809 and $108,636 for ATZ, respectively. We also found that the cost of the drug itself is the main driver for the overall healthcare spending, accounting for >78% of the total costs. Additionally, we found that the cost varies depending on where patients receive these infusible MS drugs, and generally speaking, infusions received from hospital outpatient settings would be more expensive than received from home settings. In summary, this study showed that the real-world costs of these infusible MS drugs are very high. Shifting patients away from more costly hospital outpatient departments or using MS drugs that do not require infusion resources (e.g. oral/self-injectable) may help reduce the overall healthcare spending on MS.

Aim: Describe demographics, clinical characteristics, healthcare resource utilization (HCRU) and costs in people with multiple sclerosis (pwMS) switching to alemtuzumab from other disease-modifying therapies (DMTs). Patients & methods: Retrospective, observational study of IBM®MarketScan® claims database. PwMS previously treated with DMTs and initiating alemtuzumab (1 January 2013 to 31 December 2019) were identified. "Index" was date of alemtuzumab initiation (prescription filled). Results: The study cohort (n = 341) was primarily female (72%) with (mean ± standard deviation) age 45.1 ± 9.5 years. At index, duration of MS was 5.3 ± 2.8 years. HCRU (inpatient/outpatient services), outpatient costs (including MS-specific MRI and emergency room visits) and annualized relapse rate significantly reduced over the 2 years following initiation of alemtuzumab. DMT costs reduced over the same period. Conclusion: Health economic and clinical benefits were seen following switching to alemtuzumab from other DMTs for treatment of MS, in this cohort from the USA.

The measurement of serum neurofilament light chain (sNfL) is of growing importance in the field of neurology. In the management of multiple sclerosis, it can serve as a useful marker to assess disease activity and treatment response. This paper compares two available methods, namely the Single Molecule Array (Simoa) and the Ella microfluid platform, to measure longitudinal sNfL levels of 42 highly active multiple sclerosis patients treated with alemtuzumab over a period of 36 months. In order to assess the methods agreement, Bland-Altman plots and Passing-Bablok regression were analyzed. Here, we show that despite the fact that Ella measures around 24% higher values than Simoa, both are equally suitable for longitudinal sNfL monitoring.

OBJECTIVES: The rapid expansion in treatment options for relapsing-remitting multiple sclerosis (RRMS) of the past decade requires clinical decision making on the sequential prescription of these treatments. Here, we compare 360 treatment escalation sequences for patients with RRMS in terms of health outcomes and societal costs in The Netherlands. METHODS: We use a microsimulation model with a societal perspective, developed in collaboration with MS neurologists, to estimate the effectiveness and cost-effectiveness of 360 treatment sequences starting with first-line therapies in RRMS. This model integrated data on disease progression, disease-modifying treatment efficacy, clinical decision rules, age-dependent relapse rates, quality of life, healthcare, and societal costs. RESULTS: Costs and health outcomes were overlapping among different treatment escalation sequences. In our model for RRMS treatment, optimal lifetime health outcomes (20.24 ± 1.43 quality-adjusted life-years [QALYs], 6.11 ± 0.30 relapses) were achieved with the sequence peginterferon-dimethyl fumarate-ocrelizumab-natalizumab-alemtuzumab. The most cost-effective sequence (peginterferon-glatiramer acetate-ocrelizumab-cladribine-alemtuzumab) yielded numerically worse health outcomes per patient (19.59 ± 1.43 QALYs, 6.64 ± 0.43 relapses), but resulted in 98 127 ± 19 134 less costs than the most effective treatment sequence. CONCLUSIONS: Effectiveness estimates of treatments have overlapping confidence intervals but the treatment sequence that yields most QALYs is not the most cost-effective option, also when taking uncertainty into account. It is important that neurologists are aware of cost constraints and its relationship with prescription behavior, but treatment decisions should be individually tailored.

PURPOSE OF REVIEW: Multiple sclerosis (MS) is a prevalent and debilitating neuroinflammatory disease associated with a significant economic burden. Direct healthcare costs, which can average $70,000 a year, have risen rapidly over the last decade and are driven by the escalating cost of disease-modifying therapies (DMTs). Despite a growing number of DMTs, annual increases in price for most DMTs have commonly exceeded 10% over the last 15 years. The high cost of MS DMTs has created economic hardships for patients in terms of high out-of-pocket costs and insurance company-induced barriers. Although generic versions of glatiramer acetate and dimethyl fumarate have provided some lower cost options, the median annual price for branded products currently exceeds $90,000. The goal of this paper is to examine the economic landscape of MS DMTs in the USA. RECENT FINDINGS: Recent economic analyses have provided new insights into the relative value of DMTs. Robust economic modeling studies suggest that costs per quality-adjusted life-year for most DMTs exceed commonly endorsed thresholds for what is considered a reasonable value in the USA. Because of higher efficacy and lower net costs, ocrelizumab and alemtuzumab are considered the best value. It is likely that generic versions of dimethyl fumarate and glatiramer acetate are also economically attractive. DMTs provide clinical benefit for patients with MS; however, their high cost can be a financial burden and impede access. High DMT prices are the principal reason why cost-effectiveness studies have indicated the economic value of most DMTs is questionable.

We assessed the prevalence and impact of COVID-19 among multiple sclerosis (MS) patients across Europe by leveraging participant data collected as part of the ongoing EU IMI2 RADAR-CNS major programme aimed at finding new ways of monitoring neurological disorders using wearable devices and smartphone technology. In the present study, 399 patients of RADAR-MS have been included (mean age 43.9 years, 60.7% females) with 87/399 patients (21.8%) reporting major symptoms suggestive of COVID-19. A trend for an increased risk of COVID-19 symptoms under alemtuzumab and cladribine treatments in comparison to injectables was observed. Remote monitoring technologies may support health authorities in monitoring and containing the ongoing pandemic.

Aims: The study evaluated the real-world cost of treatment in multiple sclerosis (MS) patients initiating infused disease-modifying-therapies (DMT) in the United States.Materials and Methods: This retrospective cohort study using administrative claims data included adult patients with MS initiating index infusion DMT (ocrelizumab (OCR), natalizumab (NTZ) or alemtuzumab (ATZ)) from April 2017-September 2018 with 6-months pre/12-months post-index continuous enrollment. The primary cohort included patients who had prescribed annual dosing visits indicated by the approved product label (PL): 3 OCR, 5 ATZ, and 12-13 NTZ infusion visits within the first year of initiation. Annual treatment cost was the sum of all costs on index DMT infusion visit dates. Costs were summarized for a primary and secondary cohort of patients receiving additional doses than prescribed in PL (>3 OCR, >5 ATZ, and >13 NTZ infusion visits); and an overall cohort of patients who met minimum required annual dose (≥3 OCR, ≥5 ATZ, and ≥12 NTZ), further stratified by insurance type.Results: For patients in the primary cohort (123 OCR, 18 ATZ, and 48 NTZ), mean (standard-deviation) annual cost of treatment with OCR, ATZ, and NTZ cohorts was $72,066 ($34,480), $121,053 ($51,097) and $93,777 ($38,815), respectively. Among patients initiating OCR and NTZ, 15 and 6% respectively, had additional infusion visits leading to greater costs. Mean annual costs of index infusion DMT treatment in the overall cohort (162 patients treated with OCR, 18 with ATZ, 56 with NTZ) were $80,582, $121,053, and $93,807, respectively. The mean costs for commercial enrollees were higher than those for MAPD enrollees.Limitations: Small sample size, limited population generalizability, and cost-reduction for ATZ beyond the second year need to be accounted for.Conclusions: Real-world infusion DMT treatment costs for commercially insured patients were higher than perceived expenditures based on wholesale acquisition cost and administration costs via a physician-fee schedule. Consideration of real-world costs in cost-effectiveness and treatment/coverage decisions is needed.

Allogeneic hematopoietic cell transplantation (HCT) has the capacity to cure numerous malignant and nonmalignant disorders. A dreaded complication is graft failure (GF), as it puts patients at high risk of infection and disease relapse. There are few contemporary data on the risks, outcomes, and economic burden of GF in pediatric patients. In this study, we address this gap by focusing on 14 years of transplant at our single center, for which data are compared in 2 time periods: 2005 to 2010 (n = 146) and 2011 to 2018 (n = 144). In the 290 patients studied, the median age was 9.33 years, and 50.3% had malignant versus nonmalignant disease. Cell source included bone marrow (51%), cord blood (19.7%), unmanipulated peripheral blood stem cells (PBSCs; 12.1%), and CD34-selected PBSCs (17.2%). Twenty-one percent of patients had reduced-intensity conditioning (RIC), and 54.8% of transplants were fully HLA matched. Most patients received serotherapy with rabbit anti-thymocyte globulin (39.3%) or alemtuzumab (42.8%). The incidence of neutropenic and non-neutropenic GF (NGF and NNGF) was 6.6% and 3.8%, respectively. Multivariate analysis demonstrated alemtuzumab (odds ratio [OR], 6.256, P < .001) was the main variable associated with a higher rate of GF in both time periods, whereas RIC (OR, 11.8, P < .001) and cell source (CD34-selected PBSCs; OR, 4.22, P = .04) showed period-specific effects. Specifically, from time periods 1 to 2, cord blood transplants were discontinued at our center, with a concomitant increase in CD34-selected grafts and a shift from more episodes of NGF to NNGF. Overall survival was 69% in the entire HCT cohort and 50% among patients with GF. Survival among GF patients improved from time periods 1 to 2 (20% versus 80%, P = .001), potentially due to a higher incidence of NNGF and increased ability to perform stem cell boosts from the same donor once cord blood transplants were phased out. Inpatient length of stay was consistently higher for patients with GF. Similar trends were seen for inpatient costs, although improvements were seen in our entire HCT population over time. In summary, GF remains a significant challenge in pediatric HCT and poses an economic burden on the health care system.

BACKGROUND: Alemtuzumab is a highly effective therapy for relapsing-remitting multiple sclerosis (RRMS), and immune thrombocytopenia (ITP) has been identified as a risk. OBJECTIVE: To examine ITP incidence, treatment, and outcomes during the clinical development of alemtuzumab for RRMS and discuss postmarketing experience outside clinical trials. METHODS: CAMMS223 and Comparison of Alemtuzumab and Rebif® Efficacy in Multiple Sclerosis (CARE-MS) I and II investigated two annual courses of alemtuzumab 12 mg (or 24 mg in CAMMS223/CARE-MS II) versus subcutaneous interferon beta-1a three times per week. Patients completing core studies could enroll in an extension. Monthly monitoring for ITP continued until 48 months after the last alemtuzumab infusion. RESULTS: Of 1485 alemtuzumab-treated MS patients in the clinical development program, 33 (2.2%) developed ITP (alemtuzumab 12 mg, 24 [2.0%]; alemtuzumab 24 mg, 9 [3.3%]) over median 6.1 years of follow-up after the first infusion; most had a sustained response to first-line ITP therapy with corticosteroids, platelets, and/or intravenous immunoglobulin. All cases occurred within 48 months of the last alemtuzumab infusion. Postmarketing surveillance data suggest that the ITP incidence is not higher in clinical practice than in clinical trials. CONCLUSION: Alemtuzumab-associated ITP occurs in approximately 2% of patients and is responsive to therapy. Careful monitoring is key for detection and favorable outcomes.

Objective: To evaluate individual neurofilament light chain (NfL) variation over the time of disease course and the potential of NfL measurement to predict treatment response in patients with MS. Methods: We investigated 15 patients with MS after immune reconstitution treatment with alemtuzumab (ATZ). Monthly serum NfL (sNFL) measurements were correlated with Expanded Disability Status Scale (EDSS), MRI, and relapse activity over an observational period of up to 102 months. Results: Before ATZ, sNfL was significantly increased in correlation with previous relapse/MRI activity. After ATZ, sNfL decreased quickly within the first 6 months. In patients classified as NEDA-3, sNfL declined and persisted at an individual low steady-state level of <8 pg/mL. During follow-up, 34 sNfL peaks with a >20 fold increase could be detected, which were associated with clinical or MRI disease activity. Even patient-reported relapse-suspicious symptoms, which have not been confirmed because relapses were accompanied by sNfL, increase, proposing sNfL assessment as a marker for relapse activity. sNfL started to increase earliest 5 months before, peaked at clinical onset, and recovered within 4-5 months. sNfL presented at higher levels in active patients requiring ATZ retreatment compared with responder patients. During 2 documented pregnancies, sNfL was at a low level, whereas a postpartum transient sNfL increase was seen without any signs of activity. Conclusions: This study applied a long-term high-frequency sNfL assessment in an ATZ-treated cohort, allowing a holistic profiling on the individual level and highlighted that sNfL can eminently complement the individual clinical and MRI monitoring in clinical practice.

BACKGROUND: Autoimmune disorders including nephropathies have been reported more frequently in alemtuzumab-treated multiple sclerosis (MS) patients than in the general population. OBJECTIVE: Describe instances of autoimmune nephropathy in alemtuzumab-treated MS patients. METHODS: Cases were identified from safety monitoring within the alemtuzumab relapsing-remitting multiple sclerosis (RRMS) clinical development program (CDP) or post-marketing, or following off-label use. RESULTS: As of 16 June 2017, 16 autoimmune nephropathies have occurred following alemtuzumab treatment for MS. The incidence of autoimmune nephropathies was 0.34% within the CDP (5/1485 patients). The five CDP cases (one of anti-glomerular basement membrane (anti-GBM) disease, two of membranous glomerulonephropathy, and two of serum anti-GBM antibody without typical anti-GBM disease) were identified early, responded to conventional therapy (where needed), and had favorable outcomes. Three of 11 cases outside the CDP occurred following off-label alemtuzumab use prior to approval for RRMS and were all anti-GBM disease. Diagnosis was delayed in one of these three cases and another did not receive appropriate treatment; all three cases resulted in end-stage renal failure. All anti-GBM disease cases with documented urinalysis demonstrated prior microscopic hematuria. CONCLUSION: Close monitoring of alemtuzumab-treated MS patients facilitates diagnosis and treatment early in the nephropathy course when preservation of renal function is more likely.

PURPOSE: We applied Multi-Criteria Decision Analysis (MCDA) methods in a structured benefit-risk assessment of cladribine and newer approved disease-modifying drugs (DMDs) for patients with relapsing-remitting multiple sclerosis (RRMS). METHODS: Decision conferencing with clinical neurologists as decision makers was used to create an MCDA model that incorporated available evidence on DMDs for RRMS and clinical judgments about the relevance of the evidence. Benefit-risk assessments were conducted for DMDs in both patients with RRMS and patients with RRMS with high disease activity (HDA; defined as ≥2 relapses in the previous year). Treatment options included cladribine and recently approved DMDs available in European Union countries at the time of assessment (December 2015): alemtuzumab, dimethyl fumarate, fingolimod, natalizumab, and teriflunomide. To account for the relative importance of DMD effects, scores for the MCDA model were weighted to ensure that the most clinically important attributes carried more weight in the final benefit-risk calculation. The neurologists weighted different efficacy and safety profile attributes without any reference to individual DMDs to disassociate the assessment of weights with any specific DMD. The neurologists did not do direct comparisons between DMDs. FINDINGS: The highest overall weighted preference value for the RRMS model was for dimethyl fumarate (63) followed closely by cladribine (62). For patients with RRMS and HDA, cladribine had the highest overall weighted preference value (76), followed by alemtuzumab (62) and natalizumab (61). The benefit-risk balance of cladribine in patients with RRMS and specifically patients with RRMS who exhibited HDA characterized by high relapse activity (≥2 relapses in the previous year) was more favorable than the other DMDs included in the model. IMPLICATIONS: The balance of high efficacy and the safety profile makes cladribine an important treatment option to consider, both in patients with RRMS and patients with HDA. Regular, single-country meetings could be organized to explore how differences in cultural values (scores and weights) and updated input data might affect the usefulness of MCDA in different, real-world, dynamic clinical settings.

OBJECTIVE: To evaluate the cost-effectiveness of alemtuzumab compared with fingolimod, natalizumab, ocrelizumab, and generic glatiramer acetate 20 mg among patients with relapsing multiple sclerosis (RMS) in the United States. STUDY DESIGN: Markov model with annual periods from payer perspective. METHODS: The modeled population represented pooled patients from the CARE-MS I and II trials. Therapies' comparative efficacy at reducing relapses and slowing disability worsening was obtained from network meta-analyses. Safety information was extracted from package inserts. Withdrawal rates, treatment waning, resource use, cost, and utility inputs were derived from published studies and clinical expert opinion. To project the natural history of disease worsening, data from the British Columbia cohort was used. RESULTS: Alemtuzumab dominated comparators by accumulating higher total quality-adjusted life-years (QALYs) (8.977) and lower total costs ($421 996) compared with fingolimod (7.955; $1 085 814), natalizumab (8.456; $1 048 599), ocrelizumab (8.478; $908 365), and generic glatiramer acetate (7.845; $895 661) over a 20-year time horizon. Alemtuzumab's dominance was primarily driven by savings in treatment costs because alemtuzumab has long-term duration of response and is initially administered as 2 annual courses, with 36.1% of patients requiring retreatment over 5 years, whereas comparators are used chronically. In model scenarios where alemtuzumab's long-term duration of response was assumed not to hold and therapy had to be administered annually, probabilistic sensitivity analyses showed that alemtuzumab remained cost-effective versus ocrelizumab at a willingness-to-pay threshold of $100 000/QALY in 74% to 100% of model runs. CONCLUSIONS: Alemtuzumab was a cost-effective therapy. Model results should be used to optimize clinical and managed care decisions for effective RMS treatment.

BACKGROUND: Multiple sclerosis (MS), a chronic progressive, demyelinating, inflammatory disease, affects 2.5 million people worldwide. Approximately 63% of cases are classified as relapsing-remitting MS (RRMS) at the time of diagnosis. The aim of this cost-utility analysis is to evaluate alemtuzumab vs interferon beta (intramuscular [IM] interferon beta-1a, subcutaneous [SC] interferon beta-1a, SC interferon beta-1b, and SC pegylated interferon beta-1a) in previously treated, and vs SC interferon beta-1a, fingolimod, and natalizumab in untreated RRMS patients to determine the incremental cost-effectiveness ratio among the treatment alternatives as prices, the route, and the frequency of administration of considered products vary significantly. METHODS: The primary outcome was the modeled incremental cost-effectiveness ratio (ICER; /quality-adjusted life-year [QALY] gained). Markov modeling with a 10-year time horizon was carried out. During each 3-month cycle, patients maintained the Expanded Disability Status Scale (EDSS) score or experienced progression, developed secondary progressive MS (SPMS), or showed EDSS progression in SPMS; experienced relapses; suffered from an adverse event (AE); changed treatment; or died. A published network meta-analysis (NMA) was used for indirect comparison. The possibility of a therapy switch was considered. Clinical input data and resource utilization data were derived from the literature. Costs were extracted from price lists published in Austria and were calculated from the payer's perspective. RESULTS: In treatment naïve patients, alemtuzumab is associated with costs of 132,663 and 5.25 QALYs in a 10-year time horizon. Costs for SC interferon beta amount to 164,159 and generate 4.85 QALYs. Also, in the pre-treated patients, alemtuzumab dominated comparators by accumulating higher total QALYs (4.88) and lower total costs (137.409) compared to interferon beta-1a (200.133), fingolimod (240.903), and natalizumab (247.758). CONCLUSION: The analysis shows that alemtuzumab is a cost-saving alternative to treat RRMS in pre-treated and therapy naïve patients. From the patient perspective, alemtuzumab improves quality-of-life.

OBJECTIVES: Previous research studies have highlighted differences in rejection and graft survival across sexes that favor men. We compared delayed graft function, rejection, graft survival, and overall patient survival between sexes following alemtuzumab induction. MATERIALS AND METHODS: After Internal Review Board approval, a retrospective analysis of kidney transplants completed at the University of Toledo Medical Center between March 2004 and November 2015 was conducted. RESULTS: During the study period, 675 transplants were performed. This included 429 male patients (63.6%) and 246 female patients (36.4%). Recipient sex was not associated with delayed graft function. Acute rejection occurred less frequently in women than in men at 3 months (12.6% vs 20.7%; P = .009) and at 6 months (15.9% vs 24.6%; P = .008). Cumulative patient survival was superior in women (P = .032). Female recipient death-censored graft survival was inferior at 3 years (85.4% vs 91.6%; P = .034) and at 5 years (77.7% vs 86.9%; P = .019) versus male patients. CONCLUSIONS: Compared with men, early female rejection is reduced and overall female survival is longer after alemtuzumab induction. However, intermediate-term female graft survival is less.

BACKGROUND: Alemtuzumab and natalizumab are approved as second-line therapies for relapsing-remitting multiple sclerosis (RRMS) patients in Iran who have shown an inadequate response to other disease-modifying therapy (DMT). In the absence of head-to-head trials, evaluations based on decision analytic modeling may be a suitable alternative to compare alemtuzumab and natalizumab in RRMS. PURPOSE: To evaluate the cost-effectiveness of alemtuzumab compared with natalizumab in RRMS in Iran, based on an indirect comparison of clinical trial data. METHODS: A cost-utility analysis was conducted using a cohort-based Markov model to analyze cost-utility in a cohort of 1,000 RRMS patients treated with alemtuzumab or natalizumab who had failed at least one previous DMT. Costs were measured in 2018 US Dollars, and were estimated from both the societal and National Healthcare Service (NHS) perspective over a 20-year time horizon in Iran. One-way deterministic sensitivity analyses were carried out to investigate the impact of individual variables on model results. RESULTS: Alemtuzumab dominated natalizumab in both NHS and societal perspective analyses. From the NHS perspective, the total discounted costs per patient were estimated at $147,417 and $150,579 for alemtuzumab and natalizumab, respectively, over 20 years. The discounted quality-adjusted life years were estimated to be 7.07 and 6.05, respectively. Results were similar for the societal perspective analysis. Results were most sensitive to acquisition costs and the time horizon, while no sensitivity was observed for Expanded Disability Status Scale (EDSS) health-states utility, relapse relative risk, adverse event or EDSS-related costs, and laboratory/monitoring costs. CONCLUSION: Alemtuzumab was dominant in the treatment of RRMS compared with natalizumab due to lower total cost, greater efficacy and slowing of disease progression, and lower rate of relapses over a 20-year time horizon in Iran. Comparative head-to-head trials and long-term follow-up are needed to confirm these results.

OBJECTIVES: Our aim was to assess outcomes in White and African American kidney transplant recipients after induction with alemtuzumab. MATERIALS AND METHODS: We performed a retrospective study of 464 patients who received deceased-donor kidney transplants and were induced with alem-tuzumab between March 2006 and May 2015. We evaluated ethnic influences on patient and graft survival, delayed graft function, allograft failure, and rejection. RESULTS: There were 337 White (67.3%) and 127 African American (25.3%) patients. We observed no significant differences in 1-, 3-, 5-, and 7- year death-censored graft survival. We also observed no significant differences in 1-, 3-, and 5-year patient survival rates. Having African American ethnicity was not a significant predictor of rejection, graft survival, or patient survival. CONCLUSIONS: Our results indicate that recipient ethnicity is not a predictor of rejection, graft survival, or patient survival. White and African American kidney transplant recipients induced with alemtuzumab experienced an equalization of outcomes.
