Judicialization of Zolgensma in the Ministry of Health: costs and clinical profile of patients.

OBJECTIVE: To investigate the costs and profile of patients who have filed a lawsuit against the Ministry of Health for the treatment of spinal muscular atrophy (SMA) with the onasemnogene abeparvovec (Zolgensma®). METHODS: This is a cross-sectional, descriptive study with a census design, based on records of lawsuits filed against the Ministry of Health between January 2019 and September 2022. Data was requested from the Ministry of Health via the Access to Information Act. Information was extracted on the epidemiological profile of the beneficiaries of the lawsuits, as well as the expenses spent by the Ministry of Health in cases where the requests were granted. RESULTS: 136 lawsuits were identified, of which 113 (83%) were favorable to patients at a cost of R$ 944.8 million in the period analyzed. Demographic (gender and age), clinical (SMA subtypes, use of ventilatory or nutritional support), and lawsuit (type of legal service) characteristics were not associated with the granting of lawsuits. Prior use of medication (nusinersena or ridisplam) was associated with the dismissal of lawsuits. Of the 113 lawsuits granted in favor of patients, only six (5.3%) would meet the criteria currently established by the National Committee for Health Technology Incorporation - Conitec (children up to six months without ventilatory and nutritional support). R$ 146 million was spent on supplying Zolgensma to children over the age of two, which is outside the recommendation contained in the drug's package leaflet. CONCLUSIONS: The Ministry of Health incurs a high cost with the judicialization of Zolgensma for SMA, representing 2.45% of total spending on medicines in the Unified Health System, including spending by the three administrative spheres. Some of the lawsuits have been granted in disagreement with the criteria established by health technology assessment agencies and the drug manufacturer's recommendations.

Cost-Effectiveness of Technologies for the Treatment of Spinal Muscular Atrophy: A Systematic Review of Economic Studies.

OBJECTIVES: This study aims to systematically collect data on cost-effectiveness analyses that assess technologies to treat type I and II spinal muscular atrophy and evaluate their recommendations. METHODS: A structured electronic search was conducted in 4 databases. Additionally, a complementary manual search was conducted. Complete economic studies that evaluated nusinersen, risdiplam, onasemnogene abeparvovec (OA), and the best support therapy (BST) from the health system's perspective were selected. The incremental cost-effectiveness ratios were compared with various thresholds for the analysis. The review was registered a priori in PROSPERO (CRD42022365391). RESULTS: Twenty studies were included in the analyses. They were all published between 2017 and 2022 and represent the recommendations in 8 countries. Most studies adopted 5, 6, or 10-state Markov models. Some authors took part in multiple studies. Four technologies were evaluated: BST (N = 14), nusinersen (N = 19), risdiplam (N = 5), and OA (N = 9). OA, risdiplam, and nusinersen were considered inefficient compared with the BST. Risdiplam and OA were generally regarded as cost-effective when compared with nusinersen. Because nusinersen is not a cost-effective drug, no recommendation can be derived from this result. Risdiplam and OA were compared in 2 studies that presented opposite results. CONCLUSIONS: Nusinersen, risdiplam, and OA are being adopted worldwide as a treatment for spinal muscular atrophy. Despite that, the pharmacoeconomic analyses show that the technologies are not cost-effective compared with the BST. The lack of controlled studies for risdiplam and OA hamper any conclusions about their face-to-face comparison.

Characterization of Adult Patients With SMA Treated in US Hospital Settings: A Natural History Study in the Premier Healthcare Database.

BACKGROUND: Spinal muscular atrophy (SMA) is a rare genetic disease characterized by progressive muscular weakness and atrophy resulting from motor neuron degeneration. Limited information is available on disease progression among older SMA patients, particularly adults. OBJECTIVE: This study sought to characterize the natural history of SMA among adult patients in US hospital settings through the assessment of symptoms, complications, costs, and healthcare resource utilization (HRU) over 3 years before the availability of disease-modifying therapies. METHODS: The study population included adult (≥18 years) patients with inpatient and/or hospital-based outpatient discharge records and ≥2 primary or secondary SMA ICD-9 codes ≥30 days apart in the Premier Healthcare Database during the main study period (2007-2014). Index date was the date of the first SMA ICD-9 code. The frequency of SMA-related symptoms and complications was assessed 1 year preindex through 2 years postindex to characterize disease progression. Costs and HRU were also assessed across the study period. RESULTS: A total of 446 adult patients from 337 US hospitals met inclusion criteria for these analyses. All evaluated SMA-related symptoms and complications increased steadily over time, from 1 year preindex to 2 years postindex both overall and in each age group. Adult patients with SMA had increasing total costs and HRU over the 3-year study period: total costs were $1,759 preindex and $12,308 by 2 years postindex. CONCLUSIONS: Findings are consistent with increasing disease burden over time and support the progressive nature of SMA for adult patients with hospital interactions.

Direct Medical Costs of Spinal Muscular Atrophy in the Catalonia Region: A Population-Based Analysis.

BACKGROUND: Spinal muscular atrophy (SMA) is a rare disorder, estimated to affect 1 per 10,000 live births. Patients affected with SMA often require intensive, chronic healthcare, which represents great social and economic costs. OBJECTIVE: This study aimed to evaluate the direct medical costs of SMA, from the National Health System perspective in Catalonia, and provide regional data for the development of optimal disease management protocols and resource allocation decisions at the regional level. METHODS: A retrospective, population-based study was designed based on admission records from primary care centres, hospitals and specialised care settings (inpatient and outpatient care), emergency services and extended care facilities obtained from a regional governmental claims database. RESULTS: A total of 396 patients met the inclusion criteria. Annual direct medical costs summed €58,606 per patient, taking into account the use of healthcare resources at all levels of care and excluding the cost of prescription medication. Specialised care represented 81% of the expenses that were mostly associated with respiratory manifestations of SMA. In the year 2016, 71.26% of patients with SMA had four or more systems affected by a chronic condition, versus 23.50% in the general population, which had an impact on healthcare use. CONCLUSIONS: Inpatient extended care and the increased presence of multimorbid chronic conditions in patients with SMA must be taken into account in order to develop multidisciplinary treatment protocols that reflect the complexity of SMA. Forthcoming resource allocation decisions should reflect the intensive use of specialised care registered in patients with SMA.

[Gene-based therapies of spinal muscular atrophy: a piece of history of medicine]. / Thérapies géniques de l'amyotrophie spinale infantile - Un morceau d'histoire de la médecine.

It is worth stating that a generation is needed to bring about a new family of drugs. After the deciphering of the genetic cause in 1995, two innovative classes of therapeutics are now available for spinal muscular atrophy (SMA): the repeated administration of antisens oligonucleotides and the one-shot administration of a scAAV9-SMN as a gene therapy. By addressing the genetic mechanisms of the disease, these drugs fundamentally change its course. These major advances in an extremely severe disease, often fatal before the age of 18 months in the type 1 form (50% of patients), pave the way for the treatment of other serious pathologies of the nervous or neuromuscular system, and provide unambiguous evidence of the effectiveness of these new classes of drugs called to address a number of genetic or acquired diseases. These breakthroughs raise also new scientific and technological questions (limited production yields of gene therapy drugs) but also ethical issues (access of patients to these innovative therapies) that resonate beyond this disease alone.

TITLE: Thérapies géniques de l'amyotrophie spinale infantile - Un morceau d'histoire de la médecine. ABSTRACT: On convient de dire qu'une génération est nécessaire pour faire émerger une nouvelle famille de médicaments. L'amyotrophie spinale infantile (SMA), après l'élucidation du gène causal en 1995, dispose depuis peu de deux classes innovantes de thérapeutiques : l'administration répétée d'oligonucléotides antisens et l'administration unique d'une thérapie génique par scAAV9-SMN. En s'adressant aux mécanismes génétiques de la maladie, elles en modifient fondamentalement le cours. Ces avancées majeures dans une maladie extrêmement sévère, mortelle souvent avant l'âge de 18 mois dans les formes de type 1 (50 % des malades), ouvrent la voie pour d'autres pathologies graves du système nerveux ou neuromusculaire, et apportent une preuve déterminante de l'efficacité de ces classes nouvelles de produits appelés à s'adresser à de nombreuses maladies génétiques ou acquises. Elles génèrent aussi de nouvelles questions d'ordre scientifique et technologique (capacités limitées de production des quantités nécessaires en thérapie génique) mais également d'ordre éthique (conditions d'accès des malades à ces thérapies innovantes), qui résonnent au-delà de cette seule maladie.

Patient characteristics and hospitalisation costs of spinal muscular atrophy in Spain: a retrospective multicentre database analysis.

OBJECTIVES: To analyse the characteristics of patients diagnosed with spinal muscular atrophy in Spain, and to revise data on disease management and use of resources in both public and private healthcare centres. DESIGN: A retrospective multicentre database analysis. SETTING: 870 admission records registered between 1997 and 2015 with a diagnosis of spinal muscular atrophy were extracted from a Spanish claims database that includes hospital inpatient and outpatient admissions from 313 public and 192 private hospitals in Spain. RESULTS: Admission files corresponded to 705 patients; 61.99% were males and 38.01% females. Average patient age was 37 years. Disease comorbidities registered during the admission consistently included hypertension, scoliosis and respiratory failures, all associated with the standard disease course. Regarding disease management at the hospital level, patients were mostly admitted through scheduled appointments (58.16%), followed by emergency admissions (41.72%), and into neurology services in 17% of the cases. Mean hospitalisation time was 10.45 days and in-hospital mortality reached 5.29%. The overall direct medical costs of spinal muscular atrophy were €291 525, excluding medication. The average annual cost per admission was €6274, with large variations likely to reflect disease complexity and that increases with length of stay. CONCLUSIONS: The rarity of the disease difficulties the study of demographics and management; yet, an analysis of patient characteristics provides necessary information that can be used by governments to establish more efficient healthcare protocols. This study reflects the impact that individual needs and disease severity can have in disease burden calculations. Forthcoming decision-making policies should take into account medical costs and its variability, as well as pharmaceutical expenses and indirect costs. To our knowledge, this is the first study evaluating the use of healthcare resources of patients with spinal muscular atrophy in Spain.

Value-Based Pricing for Emerging Gene Therapies: The Economic Case for a Higher Cost-Effectiveness Threshold.

While one-time gene replacement therapies may offer transformative innovation for the management of ultrarare, health-catastrophic diseases, they also pose challenges to the current U.S. health care system. Historically, the United States and other countries have demonstrated a willingness to support higher prices for health gains in rare diseases. However, payers may be ill-prepared to address reimbursement based on single administrations associated with gene therapies. As yet, there is no consensus on how to appropriately reward gene therapy innovation. The purpose of this article is to characterize challenges for traditional approaches to assessing the value of one-time gene replacement therapies and to provide a health economic rationale for a higher value-based cost-effectiveness threshold (CET). There is a general recognition that ultrarare, health-catastrophic conditions should be judged against a higher CET. The Institute for Clinical and Economic Review in the United States has discussed a range of up to $500K per quality-adjusted life-year (QALY) gained for ultrarare diseases, and the National Institute for Health and Care Excellence in the United Kingdom has described a variable threshold up to £300,000 per QALY depending on the magnitude of the health gains. In practice, health technology assessment decision makers often make comparisons to "benchmarks" to justify both standard and extraordinary CETs. We briefly review and present a list of relevant benchmarks. We also sketch out how a broader concept of value could provide the basis for higher CETs for some ultrarare diseases. This approach is outlined by the recent International Society for Pharmacoeconomics and Outcomes Research Special Task Force on Value Assessment Frameworks. In addition to the QALY gains, other elements of value related to uncertainty may also be important. They include insurance value, severity of disease, real option value, value of hope, and equity. A gene therapy currently in development for the treatment of spinal muscular atrophy (SMA) provides an exemplar for discussing the issues that accompany one-time gene replacement therapies. It is imperative that we find a consensus on how to appropriately reward value created by these gene therapies to incentivize appropriate risk taking and investments by their developers-a higher CET would, by economic logic, support a higher value-based price. If consensus on appropriate rewards cannot be found for safe and effective gene therapies for diseases such as SMA with clear criticality and unmet need, it will be even more difficult to do so for diseases where the value provided is less apparent.

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.

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.

Financial, opportunity and psychosocial costs of spinal muscular atrophy: an exploratory qualitative analysis of Australian carer perspectives.

OBJECTIVES: Spinal muscular atrophy (SMA) has profound implications for patients and families. The aim of the present study was to gain insights into the effects caring for a child with SMA has on the costs incurred by families caring for a child with SMA from carer perspectives to identify gaps in provision of care, inform public policy and cost-effectiveness analyses. DESIGN: Interpretive phenomenological analysis guided the delivery and analysis of semi-structured interviews undertaken to explore the financial, opportunity and psychosocial costs associated with caring for children with SMA. PARTICIPANTS AND SETTING: Parents of children with SMA types II and III from a single Australian paediatric neuromuscular clinic participated in this study. RESULTS: A range of experiences were reported and information saturation (n=7) was reached endorsing themes, including: significant financial and caregiving burdens, adjusted career choices and limitations on career progression and a complex landscape of access to funding, equipment, support and resources. Opportunity costs of foregone employment, purchases and leisure activities were substantial, as were emotional and social impacts. Participants voiced determination and resilience, and called for continued efforts to improve supportive care services and resources. CONCLUSIONS: The range and nature of costs met by families caring for a child with SMA were found to be expansive and not typically recognised. These include high direct costs associated with goods and services, indirect costs associated with voluntary care, substantial and long-term opportunities foregone in paid employment and career progression and unmeasured or hidden costs associated with mental health burden.

Social/economic costs and health-related quality of life in patients with spinal muscular atrophy (SMA) in Spain.

BACKGROUND: The aim of this study was to determine the economic burden and health-related quality of life (HRQOL) of patients with Spinal Muscular Atrophy (SMA) and their caregivers in Spain. METHODS: This was a cross-sectional and retrospective study of patients diagnosed with SMA in Spain. We adopted a bottom up, prevalence approach design to study patients with SMA. The patient's caregivers completed an anonymous questionnaire regarding their socio-demographic characteristics, use of healthcare services and non-healthcare services. Costs were estimated from a societal perspective (including healthcare costs and non-healthcare costs), and health-related quality of life (HRQOL) was assessed using the EQ-5D questionnaire. The main caregivers also answered a questionnaire on their characteristics and on their HRQOL. RESULTS: A total of 81 caregivers of patients with different subtypes of SMA completed the questionnaire. Based on the reference unitary prices for 2014, the average annual costs per patient were € 33,721. Direct healthcare costs were € 10,882 (representing around 32.3% of the total cost) and the direct non-healthcare costs were € 22,839 (67.7% of the total cost). The mean EQ-5D social tariff score for patients was 0.16, and the mean score of the EQ-5D visual analogue scale was 54. The mean EQ-5D social tariff score for caregivers was 0.49 and their mean score on the EQ-5D visual analogue scale was 69. CONCLUSION: The results highlight the burden that SMA has in terms of costs and decreased HRQOL, not only for patients but also for their caregivers. In particular, the substantial social/economic burden is mostly attributable to the high direct non-healthcare costs.

Gene therapy for spinomuscular atrophy: a biomedical advance, a missed opportunity for more equitable drug pricing.

An experimental approach for gene therapy of spinomuscular atrophy has been reported to prevent development of the neuromuscular features of this lethal and previously untreatable disorder. The approach involves treatment of patients suffering from SMN1-associated infantile form of the disease with a splice-switching antisense oligonucleotide (ASO) that corrects aberrant splicing of the nearly identical SMN2 gene to allow the generation of functional SMN protein, thereby mitigating the development of the disease. This technique represents the first apparently effective therapy for spinal muscular atrophy (SMA) and an important documentation for ASO technology for therapy of neurodegenerative disease. These results with one form of SMA are likely to be relevant for similar applications to other SMA types and are likely to inspire application to a number of other intractable neurodegenerative diseases such as Huntington's disease, amyotrophic lateral sclerosis and possibly even the extremely common Parkinson's and Alzheimer's diseases and others. Nevertheless, the scientific and medical importance of this advance is marred by a pricing policy by the corporate sponsors that may complicate accessibility of the drug for some desperate patients.

Role of Ethnicity in Alignment Compensation: Propensity Matched Analysis of Differential Compensatory Mechanism Recruitment Patterns for Sagittal Malalignment in 288 ASD Patients From Japan, Korea, and United States.

STUDY DESIGN: Retrospective review of adult spinal deformity patients in a multiethnic database. OBJECTIVE: To investigate the role of ethnicity on recruitment of compensatory mechanisms for sagittal spinal deformity. SUMMARY OF BACKGROUND DATA: While the impacts of age, sex, and pelvic morphology on the ability to compensate for sagittal malalignment have been investigated, the role of ethnicity in compensatory mechanism recruitment is poorly understood. METHODS: Patients from USA (85% Caucasian) >25 y/o were propensity matched by age, sex, and pelvic incidence with patients from Korea and Japan. Only primary patients or those with existing fusion below T12 were retained for analysis. Groups were subclassified by deformity severity (aligned: sagittal vertical axis (SVA) <50 mm; moderate malalignment: SVA 50-100 mm; severe malalignment: SVA >100 mm). Radiographic measurements including pelvic retroversion, thoracic kyphosis, loss of lumbar lordosis (PI minus LL), cervical lordosis, and cervical SVA were compared between the groups. RESULTS: There were 288 patients (96 each in USA, KOR, JPN), with similar age (64-67 yr) and PI (49-53°). USA had smaller pelvic incidence minus lumbar lordosis in every alignment group (P <0.05). In moderate malalignment, JPN had more pelvic retroversion than USA (30° vs. 20°), and KOR had more thoracic hypokyphosis than USA (15 vs. 31°). In severe malalignment, JPN had more pelvic retroversion than USA (39° vs. 27°), and KOR had more thoracic hypokyphosis than USA (15° vs. 31°). KOR had smaller cSVA than USA in both aligned (11 vs. 27 mm) and moderate (19 vs. 31 mm) malalignment. In severe malalignment, KOR had less cervical lordosis (13° KOR vs. 15° USA vs. 27° JPN). All differences with P <0.05. CONCLUSION: Compensation for sagittal is ethnicity dependent. Korean patients favor thoracic compensation via hypokyphosis, and Japanese patients favor pelvic compensation via retroversion. Patient ethnicity should be considered when evaluating the sagittal plane and surgical correction strategies. LEVEL OF EVIDENCE: 3.

Opening the window: The case for carrier and perinatal screening for spinal muscular atrophy.

Spinal muscular atrophy (SMA) is the most common genetically inherited neurodegenerative disease that leads to infant mortality worldwide. SMA is caused by genetic deletion or mutation in the survival of motor neuron 1 (SMN1) gene, which results in a deficiency in SMN protein. For reasons that are still unclear, SMN protein deficiency predominantly affects α-motor neurons, resulting in their degeneration and subsequent paralysis of limb and trunk muscles, progressing to death in severe cases. Emerging evidence suggests that SMN protein deficiency also affects the heart, autonomic nervous system, skeletal muscle, liver, pancreas and perhaps many other organs. Currently, there is no cure for SMA. Patient treatment includes respiratory care, physiotherapy, and nutritional management, which can somewhat ameliorate disease symptoms and increase life span. Fortunately, several novel therapies have advanced to human clinical trials. However, data from studies in animal models of SMA indicate that the greatest therapeutic benefit is achieved through initiating treatment as early as possible, before widespread loss of motor neurons has occurred. In this review, we discuss the merit of carrier and perinatal patient screening for SMA considering the efficacy of emerging therapeutics and the physical, emotional and financial burden of the disease on affected families and society.
