Early Cost-Effectiveness of Onasemnogene Abeparvovec-xioi (Zolgensma) and Nusinersen (Spinraza) Treatment for Spinal Muscular Atrophy I in The Netherlands With Relapse Scenarios.

OBJECTIVES: Onasemnogene Abeparvovec-xioi (AVXS-101) is a gene therapy intended for curative treatment of spinal muscular atrophy (SMA) with an expected price of around €2 000 000. The goal of this study is to perform a cost-effectiveness analysis of treatment of SMA I patients with AVXS-101 in The Netherlands including relapse scenarios. METHODS: An individual-based state-transition model was used to model treatment effect and survival of SMA I patients treated with AVXS-101, nusinersen and best supportive care (BSC). The model included five health states: three health states according to SMA types, one for permanent ventilation and one for death. Deterministic and probabilistic sensitivity analyses were performed. Effects of relapsing to lower health states in the years following treatment was explored. RESULTS: The base-case incremental cost-effectiveness ratio (ICER) for AVXS-101 versus BSC is €138 875/QALY, and €53 447/QALY for AVXS-101 versus nusinersen. If patients relapse within 10 years after treatment with AVXS-101, the ICER can increase up to 6-fold, with effects diminishing thereafter. Only relapses occurring later than 50 years after treatment have a negligible effect on the ICER. To comply with Dutch willingness-to-pay reference values, the price of AVXS-101 must decrease to €680 000. CONCLUSIONS: Based on this model, treatment with AVXS-101 is unlikely to be cost-effective under Dutch willingness-to-pay reference values. Uncertainty regarding the long-term curative properties of AVXS-101 can result in multiplication of the ICER. Decision-makers are advised to appropriately balance these uncertainties against the price they are willing to pay now.

Estimating the annual economic burden for the management of patients with transthyretin amyloid polyneuropathy in Spain.

Background: Transthyretin amyloid polyneuropathy (ATTR-PN) is a fatal disease associated with substantial burden of illness. Three therapies are approved by the European Medicines Agency for the management of this rare disease. The aim of this study was to compare the total annual treatment specific cost per-patient associated with ATTR-PN in Spain.Methods: An Excel-based patient burden and cost estimator tool was developed to itemize direct and indirect costs related to treatment with inotersen, patisiran, and tafamidis in the context of ATTR-PN. The product labels and feedback from five Spanish ATTR-PN experts were used to inform resource use and cost inputs.Results: Marked differences in costs were observed between the three therapies. The need for patisiran- and inotersen-treated patients to visit hospitals for pre-treatment, administration, and monitoring was associated with increased patient burden and costs compared to those treated with tafamidis. Drug acquisition costs per-patient per-year were 291,076€ (inotersen), 427,250€ (patisiran) and 129,737€ (tafamidis) and accounted for the majority of total costs. Overall, the total annual per-patient costs were lowest for patients treated with tafamidis (137,954€), followed by inotersen (308,358€), and patisiran (458,771€).Conclusions: Treating patients with tafamidis leads to substantially lower costs and patient burden than with inotersen or patisiran.

Early experiences of nusinersen for the treatment of spinal muscular atrophy: Results from a large survey of patients and caregivers.

BACKGROUND: This study aimed to examine the early experience of nusinersen for spinal muscular atrophy (SMA) from the patient and caregiver perspective. METHODS: A 54-item online survey was administered to adult patients and caregivers of pediatric patients diagnosed with SMA. RESULTS: Overall, respondents (56 patients and 45 caregivers) were satisfied with nusinersen. Satisfaction was highest on changes in energy, stamina, and motor function and lowest on treatment administration and overall time commitment. Differences were noted for treatment effect sustained over time as reported by adult patients vs caregivers reporting on behalf of pediatric patients. Respondents reported insurance approval as a key barrier to access, particularly among adult patients. CONCLUSIONS: Despite therapeutic advances, there remain significant unmet needs for SMA. Challenges with administration and barriers to access potentially limit the number of patients treated or delay treatment. Continued efforts are needed to develop more treatment options and to improve access to treatments.

Cost-Effectiveness of Nusinersen and Universal Newborn Screening for Spinal Muscular Atrophy.

OBJECTIVE: To evaluate the cost-effectiveness of nusinersen with and without universal newborn screening for infantile-onset spinal muscular atrophy (SMA). STUDY DESIGN: A Markov model using data from clinical trials with US epidemiologic and cost data was developed. The primary interventions studied were nusinersen treatment in a screening setting, nusinersen treatment in a nonscreening setting, and standard care. Analysis was conducted from a societal perspective. RESULTS: Compared with no screening and no treatment, the incremental cost-effectiveness ratio (ICER) for nusinersen with screening was $330 558 per event-free life year (LY) saved, whereas the ICER for nusinersen treatment without screening was $508 481 per event-free LY saved. For nusinersen with screening to be cost-effective at a willingness-to-pay (WTP) threshold of $50 000 per event-free LY saved, the price would need to be $23 361 per dose, less than one-fifth its current price of $125 000. Preliminary data from the NURTURE trial indicated an 85.7% improvement in expected LYs saved compared with our base results. In probabilistic sensitivity analysis, nusinersen and screening was a preferred strategy 93% of the time at a $500 000 WTP threshold. CONCLUSION: Universal newborn screening for SMA provides improved economic value for payers and patients when nusinersen is available.

Economic burden of spinal muscular atrophy in the United States: a contemporary assessment.

Aims: To estimate healthcare resource utilization (HRU) and costs among patients with spinal muscular atrophy (SMA) type 1 (SMA1) in real-world practice, overall and among patients treated with nusinersen. As a secondary objective, HRU and costs were estimated among patients with other SMA types (i.e. 2, 3, or 4 combined), overall and among patients treated with nusinersen.Materials and methods: Patients with SMA were identified from the Symphony Health's Integrated Dataverse (IDV) open claims database (September 1, 2016-August 31, 2018) and were classified into four cohorts based on SMA type and nusinersen treatment (i.e. SMA1, SMA1 nusinersen, other SMA, and other SMA nusinersen cohorts). The index date was the date of the first SMA diagnosis after December 23, 2016 or, for nusinersen cohorts, the date of nusinersen initiation. The study period spanned from the index date to the earlier among the end of clinical activity or data availability.Results: Patients in the SMA1 (n = 349) and SMA1 nusinersen (n = 45) cohorts experienced an average of 59.4 and 56.6 days with medical visits per-patient-per-year (PPPY), respectively, including 14.1 and 4.6 inpatient days. Excluding nusinersen-related costs, total mean healthcare costs were $137,627 and $92,618 PPPY in the SMA1 and SMA1 nusinersen cohorts, respectively. Mean nusinersen-related costs were $191,909 per-patient-per-month (PPPM) for the first 3 months post-initiation (i.e. loading phase) and $36,882 PPPM thereafter (i.e. maintenance phase). HRU and costs were also substantial among patients in the other SMA (n = 5,728) and other SMA nusinersen (n = 404) cohorts, with an average of 44.5 and 63.7 days with medical visits PPPY and total mean healthcare costs (excluding nusinersen-related costs) of $49,175 and $76,371 PPPY, respectively.Limitations: The database may contain inaccuracies or omissions in diagnoses, procedures, or costs, and does not capture medical services outside of the IDV network.Conclusions: HRU and healthcare costs were substantial in patients with SMA, including in nusinersen-treated patients.

Oligonucleotides to the (Gene) Rescue: FDA Approvals 2017-2019.

Four decades have passed since oligonucleotides were first used to manipulate gene expression. There were few FDA approvals prior to 2016, mostly of drugs that eventually exhibited poor performance in the market. The aura of their younger siRNA relatives had also faded during the past 15 years. However, several FDA approvals have occurred in the past 4 years, restoring hope that a new era has dawned in oligonucleotide/siRNA clinical therapeutics. Here, we review the field of oligonucleotide therapeutics and provide an update on FDA approvals of oligonucleotides from 2017 until the second quarter of 2019. We take into consideration the ethical issues looming over the still somewhat limited efficacy of these molecules, the toxicity of treatment, and the exorbitant cost of these therapeutic agents, which limits accessibility for many.

[The incorporation of nusinersen by the Brazilian Unified National Health System: critical thoughts on the institutionalization of health technology assessment in Brazil]. / A incorporação do nusinersena no Sistema Único de Saúde: uma reflexão crítica sobre a institucionalização da avaliação de tecnologias em saúde no Brasil.

In April 2019, a ruling was signed for the incorporation of the drug nusinersen by the Brazilian Unified National Health System (SUS). Nusinersen is the most expensive drug ever incorporated by the SUS and is used to treat type I 5q spinal muscular atrophy. The incorporation has been described as a milestone in decision-making on new technologies in the SUS, enabled through a risk-sharing agreement. The article discusses the process involved in the incorporation of nusinersen, highlighting the context, timing, and technical issues, in addition to possible consequences for the institutionalization of health technology assessment (HTA) in the SUS. The study used an exploratory method, reviewing public information produced by the Commission for Incorporation of Technologies in the SUS (CONITEC) and searches in government databanks on prices and purchases. A timeline was produced, describing the key points in the process of incorporation. There were two formal requests for the drug's incorporation. The first was submitted by the Division of Science, Technology, and Strategic Inputs (SCTIE) of the Brazilian Ministry of Health and was turned down unanimously in November 2018. This was followed by a petition by the head of the SCTIE to the Attorney General's Office (AGU) to overrule the recommendation by the CONITEC plenary. The AGU recommended a new submission, made by the drug's manufacturing company, which was approved unanimously in March 2019. The was no addition of new evidence or a price reduction to justify the change of decision. No elements were identified in the risk-sharing agreement. This suggests problems of transparency and accountability, as well as risks in the process of institutionalization of HTA that had been underway in the SUS.

Systematic evaluation of 2'-Fluoro modified chimeric antisense oligonucleotide-mediated exon skipping in vitro.

Antisense oligonucleotide (AO)-mediated splice modulation has been established as a therapeutic approach for tackling genetic diseases. Recently, Exondys51, a drug that aims to correct splicing defects in the dystrophin gene was approved by the US Food and Drug Administration (FDA) for the treatment of Duchenne muscular dystrophy (DMD). However, Exondys51 has relied on phosphorodiamidate morpholino oligomer (PMO) chemistry which poses challenges in the cost of production and compatibility with conventional oligonucleotide synthesis procedures. One approach to overcome this problem is to construct the AO with alternative nucleic acid chemistries using solid-phase oligonucleotide synthesis via standard phosphoramidite chemistry. 2'-Fluoro (2'-F) is a potent RNA analogue that possesses high RNA binding affinity and resistance to nuclease degradation with good safety profile, and an approved drug Macugen containing 2'-F-modified pyrimidines was approved for the treatment of age-related macular degeneration (AMD). In the present study, we investigated the scope of 2'-F nucleotides to construct mixmer and gapmer exon skipping AOs with either 2'-O-methyl (2'-OMe) or locked nucleic acid (LNA) nucleotides on a phosphorothioate (PS) backbone, and evaluated their efficacy in inducing exon-skipping in mdx mouse myotubes in vitro. Our results showed that all AOs containing 2'-F nucleotides induced efficient exon-23 skipping, with LNA/2'-F chimeras achieving better efficiency than the AOs without LNA modification. In addition, LNA/2'-F chimeric AOs demonstrated higher exonuclease stability and lower cytotoxicity than the 2'-OMe/2'-F chimeras. Overall, our findings certainly expand the scope of constructing 2'-F modified AOs in splice modulation by incorporating 2'-OMe and LNA modifications.

Cost Effectiveness of Nusinersen in the Treatment of Patients with Infantile-Onset and Later-Onset Spinal Muscular Atrophy in Sweden.

BACKGROUND: Spinal muscular atrophy is a rare neuromuscular disorder with a spectrum of severity related to age at onset and the number of SMN2 gene copies. Infantile-onset (≤ 6 months of age) is the most severe spinal muscular atrophy and is the leading monogenetic cause of infant mortality; patients with later-onset (> 6 months of age) spinal muscular atrophy can survive into adulthood. Nusinersen is a new treatment for spinal muscular atrophy. OBJECTIVE: The objective of this study was to evaluate the cost effectiveness of nusinersen for the treatment of patients with infantile-onset spinal muscular atrophy and later-onset spinal muscular atrophy in Sweden. METHODS: One Markov cohort health-state transition model was developed for each population. The infantile-onset and later-onset models were based on the efficacy results from the ENDEAR phase III trial and the CHERISH phase III trial, respectively. The cost effectiveness of nusinersen in both models was compared with standard of care in Sweden. RESULTS: For a time horizon of 40 years in the infantile-onset model and 80 years in the later-onset model, treatment with nusinersen resulted in 3.86 and 9.54 patient incremental quality-adjusted life-years and 0.02 and 2.39 caregiver incremental quality-adjusted life-years and an incremental cost of 21.9 and 38.0 million SEK (Swedish krona), respectively. These results translated into incremental cost-effectiveness ratios (including caregiver quality-adjusted life-years) of 5.64 million SEK (€551,300) and 3.19 million SEK (€311,800) per quality-adjusted life-year gained in the infantile-onset model and later-onset model, respectively. CONCLUSIONS: Treatment with nusinersen resulted in overall survival and quality-adjusted life-year benefits but with incremental costs above 21 million SEK (€2 million) [mainly associated with maintenance treatment with nusinersen over a patient's lifespan]. Nusinersen was not cost effective when using a willingness-to-pay threshold of 2 million SEK (€195,600), which has been considered in a recent discussion by the Dental and Pharmaceutical Benefits Agency as a reasonable threshold for rare disease. Nonetheless, nusinersen gained reimbursement in Sweden in 2017 for paediatric patients (below 18 years old) with spinal muscular atrophy type I-IIIa.

Perspectives on Spinraza (Nusinersen) Treatment Study: Views of Individuals and Parents of Children Diagnosed with Spinal Muscular Atrophy.

BACKGROUND: Spinal muscular atrophy (SMA) is a genetic disorder characterized by muscle loss. In December 2016 the FDA approved the first and only treatment drug for SMA: Spinraza (nusinersen). Despite excitement and optimism, there are no published data on the perceptions of individuals with SMA and their families about the benefits, risks, and challenges associated with treatment. OBJECTIVE: This qualitative interview study sought to characterize the perspectives of patients/families with SMA who did not want, or were unsure about, receiving this new innovative treatment for a previously untreatable and often fatal condition. METHODS: Individuals and families were recruited via advertisements on Facebook groups related to SMA and through the Stanford Neuromuscular Contact Registry. Participants completed a demographic questionnaire and participated in a semi-structured interview via voice conferencing. Interview questions focused on: 1) experiences with SMA, 2) opinions about Spinraza treatment, and 3) factors considered in decisions regarding treatment. RESULTS: Thirteen people were interviewed: ten adults with SMA (ages 27-48, nine with Type II) and three parents of minor children with SMA (one each of Types I, II and III). Qualitative content analysis identified a range of opinions about Spinraza treatment: five were uninterested (2 adults, 3 parents), four adults were still deciding whether to pursue treatment, three adults were interested or in the process of pursuing treatment, and one adult was currently receiving the drug after overcoming significant reluctance. Participants described several key factors influencing their treatment decisions, including: concerns about risk factors and side effects, high cost, insurance coverage, time involvement, and lack of data about efficacy. Participants reported learning about most of these factors through parent/patient testimonials on SMA-specific social media groups. CONCLUSIONS: Participants reported basing decisions about pursuing Spinraza on a variety of practical and value-based considerations. They described carefully weighing the perceived potential benefits and risks of treatment through the lens of their current quality of life and prognosis. These findings suggest that providers should be aware that some patients and parents, especially those with Types II-IV, may approach treatment decisions differently than parents of children with SMA I. Informed treatment decisions can be supported through: 1) the collection and dissemination of better data on Spinraza treatment in these populations; 2) clear communication about risks, side effects and eligibility; 3) improved access to payment and treatment facilities; and 4) facilitation of discussions between providers and patients/families about identity and disability in the context of goals of care and other life and support challenges.

Putting our best foot forward: Clinical, treatment-based and ethical considerations of nusinersen therapy in Canada for spinal muscular atrophy.

Spinal muscular atrophy (SMA) is the most common genetic cause of infant mortality. SMA is a spectral disorder and is categorised based on symptom onset and severity. The median life expectancy for infants with SMA presenting before 6 months of age is less than 2 years without respiratory support. To date, there is no cure for SMA. In June 2017, nusinersen was approved in Canada as the first disease-modifying drug for SMA because of its demonstrated benefits on motor function and survival in clinical trials. However, with a price tag of almost 1 million dollars for the first year of therapy, careful clinical, treatment-based and ethical consideration of the principles of (i) best interests; (ii) universality; (iii) portability; (iv) public administration; (v) accessibility; and (vi) comprehensiveness are important guideposts to ensure transparent and equitable allocation of health-care resources for nusinersen and all other future orphan drugs.

Nusinersen treatment of spinal muscular atrophy: current knowledge and existing gaps.

Spinal muscular atrophy (SMA) is a recessive disorder caused by a mutation in the survival motor neuron 1 gene (SMN1); it affects 1 in 11 000 newborn infants. The most severe and most common form, type 1 SMA, is associated with early mortality in most cases and severe disability in survivors. Nusinersen, an antisense oligonucleotide, promotes production of full-length protein from the pseudogene SMN2. Nusinersen treatment prolongs survival of patients with type 1 SMA and allows motor milestone acquisition. Patients with type 2 SMA also show progress on different motor scales after nusinersen treatment. Nusinersen was recently approved by the European Medicines Agency and the US Food and Drug Administration; it is now reimbursed in several European countries and in the USA. In Australia, the transition from expanded access programme to commercial availability is coming soon. In New Zealand, an expanded access programme is opened, and in Canada price negotiation for the treatment is in progress. In this review we exemplify the clinical benefit of nusinersen in subgroups of patients with SMA. Nusinersen represents the first efficacious marked approved drug in type 1 and type 2 SMA. Different knowledge gaps, such as results in older patients, in patients with permanent ventilation, in patients with neonatal forms, or in patients after spinal fusion, still need to be addressed. WHAT THIS PAPER ADDS: Identifies gaps in knowledge about the efficacy of nusinersen in broader populations of patients with spinal muscular atrophy. Identifies open questions in populations of patients where proof of efficacy is available.

Gene Therapy for Spinal Muscular Atrophy: An Emerging Treatment Option for a Devastating Disease.

BACKGROUND: Spinal muscular atrophy (SMA) is an autosomal recessive neurodegenerative disease that, in most cases, involves homozygous deletion of the SMN1 gene. This causes a deficiency in survival motor neuron (SMN) protein, which plays a critical role in motor neuron development. SMA has a range of phenotype expression resulting in variable age of symptom onset, maximum motor strength achieved, and survival. Without intervention, infants with a more severe form of the disease (type 1 SMA) die before 2 years of age. Although it is rare, SMA is the most common fatal inherited disease of infancy, and until recently, treatment was primarily supportive. In 2016, a new agent, nusinersen, was approved by the FDA. Other treatments are in development, including a gene therapy, AVXS-101. These treatments are not only improving the lives of patients with SMA and their families, they are changing the disease phenotype. They have the greatest benefit when given early in the disease course. OBJECTIVES: To discuss current knowledge about SMA, provide clinical evidence for available and emerging treatment options, and present approaches for adding new therapies to hospital/health system formularies to ensure timely access to newly approved therapies for SMA. SUMMARY: Advances in clinical care have significantly extended the lives of individuals with SMA, and research into the genetic mechanisms leading to disease have revealed strategies for intervention that target the underlying cause of SMA. Nusinersen is now on the market, and other treatment options, such as AVXS-101, may soon be approved. This article provides an overview of SMA and the genetic mechanisms leading to SMN deficiency, then describes how new and emerging treatments work to overcome this deficiency and prevent associated nerve damage and disability. In addition, we discuss steps for incorporating AVXS-101 into hospital/health system formularies, along with barriers and concerns that may delay access, based in part on lessons learned with nusinersen.
