Adherence and Persistence Among Risdiplam-Treated Individuals with Spinal Muscular Atrophy: A Retrospective Claims Analysis.

INTRODUCTION: Spinal muscular atrophy (SMA) is a neuromuscular disease caused by deletions and/or mutations in the survival of motor neuron 1 (SMN1) gene. Risdiplam, the first and only oral SMN2 pre-mRNA splicing modifier, is US Food and Drug Administration-approved for the treatment of pediatric and adult patients with SMA. For patients with SMA, long-term adherence to and persistence with an SMA treatment may be important for achieving maximum clinical benefits. However, real-world evidence on patient adherence to and persistence with risdiplam is limited. METHODS: This retrospective study examined real-world adherence and persistence with risdiplam from a specialty pharmacy in patients with SMA over a 12-month period. Adherence was estimated by using proportion of days covered (PDC) and was calculated over variable (time between first and last fill) and fixed (time from first fill to study period end) intervals. Persistence was defined as no gap in supply ≥ 90 days. Patients were included if the time between the index date and study observation period was ≥ 12 months, if they initiated risdiplam between August 2020 and September 2022, received ≥ 2 risdiplam fills, and had an SMA diagnosis associated with a risdiplam fill. Subgroup analyses of risdiplam adherence and persistence were performed by age and primary payer type. RESULTS: The proportion of patients (N = 1636) adherent at 12 months based on variable and fixed interval PDC was 93% and 79%, respectively. Adherence was high among patients on commercial insurance, Medicaid, or Medicare (range 86-96%). Mean persistence was 330.4 days. The highest proportion of patients who were persistent were on Medicaid (81%). CONCLUSION: These findings demonstrate that patient adherence to and persistence with risdiplam treatment were high, including across all subgroups tested.

Results of a Pilot External Quality Assessment Scheme for Genetic Testing of Newborns with Spinal Muscular Atrophy.

BACKGROUND: This study aims to evaluate the ability of laboratories to perform spinal muscular atrophy (SMA) genetic testing in newborns based on dried blood spot (DBS) samples, and to provide reference data and advance preparation for establishing the pilot external quality assessment (EQA) scheme for SMA genetic testing of newborns in China. METHODS: The pilot EQA scheme contents and evaluation principles of this project were designed by National Center for Clinical Laboratories (NCCL), National Health Commission. Two surveys were carried out in 2022, and 5 batches of blood spots were submitted to the participating laboratory each time. All participating laboratories conducted testing upon receiving samples, and test results were submitted to NCCL within the specified date. RESULTS: The return rates were 75.0% (21/28) and 95.2% (20/21) in the first and second surveys, respectively. The total return rate of the two examinations was 83.7% (41/49). Nineteen laboratories (19/21, 90.5%) had a full score passing on the first survey, while in the second survey twenty laboratories (20/20, 100%) scored full. CONCLUSIONS: This pilot EQA survey provides a preliminary understanding of the capability of SMA genetic testing for newborns across laboratories in China. A few laboratories had technical or operational problems in testing. It is, therefore, of importance to strengthen laboratory management and to improve testing capacity for the establishment of a national EQA scheme for newborn SMA genetic testing.

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.

5qSMA: standardised retrospective natural history assessment in 268 patients with four copies of SMN2.

Newborn screening for 5qSMA offers the potential for early, ideally pre-symptomatic, therapeutic intervention. However, limited data exist on the outcomes of individuals with 4 copies of SMN2, and there is no consensus within the SMA treatment community regarding early treatment initiation in this subgroup. To provide evidence-based insights into disease progression, we performed a retrospective analysis of 268 patients with 4 copies of SMN2 from the SMArtCARE registry in Germany, Austria and Switzerland. Inclusion criteria required comprehensive baseline data and diagnosis outside of newborn screening. Only data prior to initiation of disease-modifying treatment were included. The median age at disease onset was 3.0 years, with a mean of 6.4 years. Significantly, 55% of patients experienced symptoms before the age of 36 months. 3% never learned to sit unaided, a further 13% never gained the ability to walk independently and 33% of ambulatory patients lost this ability during the course of the disease. 43% developed scoliosis, 6.3% required non-invasive ventilation and 1.1% required tube feeding. In conclusion, our study, in line with previous observations, highlights the substantial phenotypic heterogeneity in SMA. Importantly, this study provides novel insights: the median age of disease onset in patients with 4 SMN2 copies typically occurs before school age, and in half of the patients even before the age of three years. These findings support a proactive approach, particularly early treatment initiation, in this subset of SMA patients diagnosed pre-symptomatically. However, it is important to recognize that the register will not include asymptomatic individuals.

Development of a low-cost and accurate carrier screening method for spinal muscular atrophy in developing countries.

Heterozygous carriers of the survival of motor neuron 1 (SMN1) gene deletion in parents account for approximately 95% of neonatal spinal muscular atrophy cases. Given the severity of the disease, professional organizations have recommended periconceptional spinal muscular atrophy carrier screening to all couples, regardless of race or ethnicity. However, the prevalence of screening activities in mainland China remains suboptimal, mainly attributed to the limitations of the existing carrier screening methods. Herein, we aimed to develop a low-cost, accessible, and accurate carrier screening method based on duplex droplet digital PCR (ddPCR), to cover a wider population in developing countries, including China. The receiver operating characteristic curve was used to determine the cut-off value of SMN1 copy numbers. Performance validation was conducted for linearity, precision, and accuracy. In total, 482 cases were considered to validate the concordance between the developed ddPCR assay and multiplex ligation-dependent probe amplification. Linear correlations were excellent between the expected concentration of the reference gene and the observed values (R2 > 0.99). Both the intra- and inter-assay precision of our ddPCR assays were less than 6.0%. The multiplex ligation-dependent probe amplification and ddPCR results were consistent in 480 of the 482 cases (99.6%). Two cases with multiplex ligation-dependent probe amplification, suggestive of two copies of SMN1 exon 7, were classified into three copies by ddPCR analysis. The overall correct classification of the samples included in our ddPCR assay was 100%. This study demonstrates that an appropriate cut-off value is an important prerequisite for establishing a semi-quantitative method to determine the SMN1 copy numbers. Compared to conventional methods, our ddPCR assay is low-cost, highly accurate, and has full potential for application in population spinal muscular atrophy carriers screening.

Cost-Effectiveness of Onasemnogene Abeparvovec Compared With Nusinersen and Risdiplam in Patients With Spinal Muscular Atrophy Type 1 in Brazil: Custo-Efetividade do Onasemnogeno Abeparvoveque (AVXS-101) em Comparação ao Nusinersena e Risdiplam em Pacientes com Atrofia Muscular Espinhal Tipo 1 no Brasil.

OBJECTIVES: This study aimed to evaluate the cost-effectiveness of the onasemnogene abeparvovec in relation to nusinersen and risdiplam in the treatment of spinal muscular atrophy type 1 from the perspective of the Brazilian Unified Health System. METHODS: A Markov model was built on a lifetime horizon. Short-term data were obtained from clinical trials of the technologies and from published cohort survival curves (long term). Costs were measured in current 2022 local currency (R$) values and benefits in quality-adjusted life-years (QALYs). Utility values were derived from type 1 spinal muscular atrophy literature, whereas costs related to technologies and maintenance care in each health state were obtained from official sources of reimbursement in Brazil. Deterministic and probabilistic, as well as scenario, sensitivity analyses were performed. RESULTS: Compared with the less costly strategy (nusinersen), the use of onasemnogene abeparvovec resulted in an incremental cost of R$2.468.448,06 ($975 671.169 - purchasing power parity [PPP]) and a 3-QALY increment and incremental cost-effectiveness ratio of R$742.890,92 ($293 632.774 - PPP)/QALY. Risdiplam had an extended dominance from other strategies, resulting in an incremental cost-effectiveness ratio of R$926.586,22 ($366 239.612 - PPP)/QALY compared with nusinersen. Sensitivity analysis showed a significant impact of the follow-up time of the cohort and the cost of acquiring onasemnogene abeparvovec. CONCLUSIONS: Over a lifetime horizon, onasemnogene abeparvovec seems to be a potentially more effective option than nusinersen and risdiplam, albeit with an incremental cost. Such a trade-off should be weighed in efficiency criteria during decision making and outcome monitoring from the perspective of the Brazilian Unified Health System.

Assessment of the upper limb function, strength, and mobility in treatment-naive children with spinal muscular atrophy Types 2 and 3.

INTRODUCTION/AIMS: Current upper limb assessments in pediatric spinal muscular atrophy (SMA) may not adequately capture change with disease progression. Our aim was to examine the relationship between motor function, strength, and hand/finger mobility of the upper limb in treatment-naïve children with SMA Types 2 and 3 to assess new methods to supplement current outcomes. METHODS: The Revised Upper Limb Module (RULM), grip and pinch strength, and hand/finger mobility data were collected from 19 children with SMA Types 2 and 3 aged 5.2-16.9 years over a year. RESULTS: A median loss between 0.5 and 2.5 points in the RULM was seen across all SMA subgroups with the biggest median loss recorded between 10 and 14 years of age. The grip strength loss was -0.06 kg (-4.69 to 3.49; IQR, 1.21); pinch improvement of 0.05 (-0.65 to 1.27; IQR, 0.48); hand/finger mobility test improvement of 4 points (-24 to 14; IQR, 6.75) for the whole cohort. Significant correlations were found between the RULM and grip strength (p < .001), RULM and pinch strength (p < .001), RULM and revised Brooke (p < .001), grip strength and pinch strength (p < .001). DISCUSSION: The combined use of the RULM, dynamometry, and hand mobility provide insight about correlations between function and strength in children with SMA. The RULM and grip strength assessments captured a significant decline in upper limb function, whereas the pinch and finger/hand mobility showed an improvement over the course of 1 year and these results should be considered for future studies.

Variability in Newborn Screening Across Canada: Spinal Muscular Atrophy and Beyond.

BACKGROUND: Newborn screening (NBS) identifies infants with severe, early-onset diseases, enabling early diagnosis and treatment. In Canada, decisions regarding disease inclusion in NBS programs occur at the provincial level, which leads to variability in patient care. We aimed to determine whether important differences exist in NBS programs across provinces and territories. Given that spinal muscular atrophy (SMA) is the most recent disease added to NBS programs, we hypothesized that its inclusion would show interprovincial variability and be more likely in provinces already screening for a greater number of diseases. METHODS: We conducted a cross-sectional survey of all NBS labs in Canada to understand: 1) what conditions were included in their program; 2) what genetic-based testing was performed and; 3) if SMA was included. RESULTS: All NBS programs (N = 8) responded to this survey by June 2022. There was a 2.5-fold difference in the number of conditions screened (N = 14 vs N = 36) and a 9-fold difference in the number of conditions screened by gene-based testing. Only nine conditions were common to all provincial NBS programs. NBS for SMA was performed in four provinces at the time of our survey, with BC recently becoming the fifth province to add SMA to their NBS on October 1, 2022. Currently, 72% of Canadian newborns are screened for SMA at birth. CONCLUSION: Although healthcare in Canada is universal, its decentralization gives rise to regional differences in NBS programs which creates inequity in the treatment, care, and potential outcomes of affected children across provincial jurisdictions.

Cost-effectiveness of spinal muscular atrophy newborn screening based on real-world data in Belgium.

The objective of the study was to assess the cost-effectiveness of real-world spinal muscular atrophy newborn screening followed by treatment. We modeled the lifetime cost-effectiveness of the spinal muscular atrophy newborn screening followed by treatment (screening) compared to treatment without screening (no screening) from the Belgian healthcare perspective. Real-world data, including quality of life, costs, and motor development data, were collected on 12 patients identified by screening and 43 patients identified by their symptoms. "Screening" was associated with slightly higher healthcare costs (€ 6,858,061 vs. € 6,738,120) but more quality-adjusted life years (QALY) (40.95 vs. 20.34) compared to "no screening", leading to an incremental cost-effectiveness ratio of € 5,820 per QALY gained. "Screening" was dominant from a societal perspective (negative incremental costs: € -14,457; incremental QALY = 20.61), when incorporating the burden on caregivers (negative incremental costs = € -74,353; incremental QALY = 27.51), and when the treatment was chosen by the parents (negative incremental costs = € -2,596,748; incremental QALY = 20.61). Spinal muscular atrophy newborn screening coupled with early treatment is thus cost-effective compared with late treatment following clinical diagnosis and is dominant when societal perspective, caregiver burden, and treatment based on parental preference were considered.

Judicialization of Zolgensma in the Ministry of Health: costs and clinical profile of patients / Judicialização do Zolgensma no Ministério da Saúde: custos e perfil clínico dos pacientes

ABSTRACT 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.

RESUMO OBJETIVO Investigar os custos e o perfil dos pacientes que demandaram judicialmente o onasemnogene abeparvoveque (Zolgensma®) para o tratamento da atrofia muscular espinhal (AME) no Ministério da Saúde. MÉTODOS Estudo transversal, de natureza descritiva e desenho censitário, com base em registros de ações judiciais movidas contra o Ministério da Saúde no período de janeiro de 2019 a setembro de 2022. Os dados foram solicitados ao Ministério da Saúde, via Lei de Acesso à Informação. Foram extraídas informações sobre o perfil epidemiológico dos beneficiários das ações judiciais, bem como os gastos dispendidos pelo Ministério da Saúde nos casos de deferimento das solicitações. RESULTADOS Foram identificados 136 processos judiciais, dos quais 113 (83%) foram favoráveis aos pacientes ao custo de R$ 944,8 milhões no período analisado. Características demográficas (sexo e idade), clínicas (subtipos da AME, uso de suporte ventilatório ou nutricional) e do processo judicial (tipo de serviço advocatício) não foram associadas com o deferimento das ações judiciais. O uso prévio de medicamento (nusinersena ou ridisplam) foi associado com o indeferimento dos processos judiciais. Das 113 ações judiciais concedidas em favor dos pacientes, apenas seis (5,3%) atenderiam aos critérios estabelecidos atualmente pela Comissão Nacional de Incorporação de Tecnologias - Conitec (crianças com até seis meses sem suporte ventilatório e nutricional). Houve dispêndio de R$ 146 milhões com o fornecimento do Zolgensma para crianças com idade superior a dois anos, que está fora da recomendação contida na bula do medicamento. CONCLUSÕES O Ministério da Saúde incorre em um alto custo com a judicialização do Zolgensma para AME, representando 2,45% do gasto total com medicamentos no Sistema Único de Saúde, incluindo gastos das três esferas administrativas. Parte das demandas judiciais tem sido deferida em divergência com os critérios estabelecidos por agências de avaliação de tecnologias em saúde e recomendações do fabricante do medicamento.

Digital measures of respiratory and upper limb function in spinal muscular atrophy: design, feasibility, reliability, and preliminary validity of a smartphone sensor-based assessment suite.

Spinal muscular atrophy (SMA) is characterized by progressive muscle weakness and paralysis. Motor function is monitored in the clinical setting using assessments including the 32-item Motor Function Measure (MFM-32), but changes in disease severity between clinical visits may be missed. Digital health technologies may assist evaluation of disease severity by bridging gaps between clinical visits. We developed a smartphone sensor-based assessment suite, comprising nine tasks, to assess motor and muscle function in people with SMA. We used data from the risdiplam phase 2 JEWELFISH trial to assess the test-retest reliability and convergent validity of each task. In the first 6 weeks, 116 eligible participants completed assessments on a median of 6.3 days per week. Eight of the nine tasks demonstrated good or excellent test-retest reliability (intraclass correlation coefficients >0.75 and >0.9, respectively). Seven tasks showed a significant association (P < 0.05) with related clinical measures of motor function (individual items from the MFM-32 or Revised Upper Limb Module scales) and seven showed significant association (P < 0.05) with disease severity measured using the MFM-32 total score. This cross-sectional study supports the feasibility, reliability, and validity of using smartphone-based digital assessments to measure function in people living with SMA.

Health Care Resource Utilization and Costs for Patients with Spinal Muscular Atrophy: Findings from a Retrospective US Claims Database Analysis.

INTRODUCTION: Spinal muscular atrophy (SMA) is a neurogenic disorder associated with progressive loss of muscle function, respiratory failure, and premature mortality. This study aimed to describe and compare real-world health care resource utilization (HCRU) and costs for US patients with SMA treated with disease-modifying treatments, including onasemnogene abeparvovec, nusinersen, and/or risdiplam. METHODS: This study used claims and structured electronic medical record data from the HealthVerity claims database (January 1, 2017-March 31, 2021). Eligible patients were aged ≤ 2 years at index (treatment initiation or switch), diagnosed with SMA, had ≥ 1 pharmacy/medical claim for onasemnogene abeparvovec, nusinersen, and/or risdiplam, and continuous enrollment ≥ 1 month pre- and ≥ 2 months post-index. SMA-related HCRU and costs during the study period (> 12 months post-index) were compared between treatment groups before and after propensity score weighting. Costs were adjusted to 2021 USD. RESULTS: Of 74 included patients, 62 (83.8%) received nusinersen and 12 (16.2%) received onasemnogene abeparvovec (monotherapy, n = 9; onasemnogene abeparvovec after nusinersen [switching], n = 3). After weighting, nusinersen-treated patients had greater annual numbers of inpatient (mean 5.3 nusinersen vs. 1.8 onasemnogene abeparvovec) and emergency department (mean 3.0 nusinersen vs. 1.5 onasemnogene abeparvovec; p < 0.05) visits, and greater annual SMA-related medical costs (mean $78,446 nusinersen vs. $29,438 onasemnogene abeparvovec; mean difference $49,007, p < 0.05) than onasemnogene abeparvovec-treated patients. Onasemnogene abeparvovec-treated patients incurred greater SMA-treatment pharmacy costs than nusinersen-treated patients (mean $2,241,875 onasemnogene abeparvovec vs. $693,191 nusinersen; mean difference $1,548,684, p < 0.05). CONCLUSIONS: SMA is associated with substantial economic burden. Patients treated with onasemnogene abeparvovec had greater SMA treatment-related pharmacy costs but lower SMA-related HCRU and medical costs compared with patients receiving nusinersen monotherapy.

Spinal muscular atrophy (SMA) is a crippling neurodegenerative disease with symptoms of respiratory failure, muscle weakness and loss of function, and premature death. This study describes and compares real-world health care resource utilization (HCRU) and costs for US patients with SMA receiving current treatments (e.g., onasemnogene abeparvovec, nusinersen, risdiplam) using claims and electronic medical record data from a US claims database. Patients included (n = 74) in the study were ≤ 2 years old at treatment initiation/switching of treatments (index), had been diagnosed with SMA and had one or more pharmacy or medical claim for onasemnogene abeparvovec, nusinersen, or risdiplam, and were continuously enrolled for ≥ 1 month before and ≥ 2 months after index. SMA-related HCRU and costs during the study period (up to 12 months post-index) were compared between treatment groups before and after propensity score weighting, with costs adjusted to 2021 USD. Propensity score weighting allows better comparison between patients in treatment and comparison groups by assigning patients different "weights." This weighting allows investigators to be certain that differences in outcomes between patient groups are a result of a particular treatment. After weighting, nusinersen-treated patients had a greater number of inpatient and emergency department visits and greater SMA-related medical costs annually, whereas patients who received onasemnogene abeparvovec had greater pharmacy costs. Our study indicates the greater medical costs among patients receiving nusinersen were largely driven by invasive procedures, such as tracheostomy and gastrostomy, that required hospitalization, but the exact mechanism of greater HCRU/costs associated with nusinersen needs to be further assessed.

Carrier Screening Programs for Cystic Fibrosis, Fragile X Syndrome, Hemoglobinopathies and Thalassemia, and Spinal Muscular Atrophy: A Health Technology Assessment.

Background: We conducted a health technology assessment to evaluate the safety, effectiveness, and cost-effectiveness of carrier screening programs for cystic fibrosis (CF), fragile X syndrome (FXS), hemoglobinopathies and thalassemia, and spinal muscular atrophy (SMA) in people who are considering a pregnancy or who are pregnant. We also evaluated the budget impact of publicly funding carrier screening programs, and patient preferences and values. Methods: We performed a systematic literature search of the clinical evidence. We assessed the risk of bias of each included study using the Cochrane Risk of Bias tool and the Risk of Bias Assessment tool for Non-randomized Studies (RoBANS), and the quality of the body of evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. We performed a systematic economic literature search and conducted cost-effectiveness analyses comparing preconception or prenatal carrier screening programs to no screening. We considered four carrier screening strategies: 1) universal screening with standard panels; 2) universal screening with a hypothetical expanded panel; 3) risk-based screening with standard panels; and 4) risk-based screening with a hypothetical expanded panel. We also estimated the 5-year budget impact of publicly funding preconception or prenatal carrier screening programs for the given conditions in Ontario. To contextualize the potential value of carrier screening, we spoke with 22 people who had sought out carrier screening. Results: We included 107 studies in the clinical evidence review. Carrier screening for CF, hemoglobinopathies and thalassemia, FXS, and SMA likely results in the identification of couples with an increased chance of having an affected pregnancy (GRADE: Moderate). Screening likely impacts reproductive decision-making (GRADE: Moderate) and may result in lower anxiety among pregnant people, although the evidence is uncertain (GRADE: Very low).We included 21 studies in the economic evidence review, but none of the study findings were directly applicable to the Ontario context. Our cost-effectiveness analyses showed that in the short term, preconception or prenatal carrier screening programs identified more at-risk pregnancies (i.e., couples that tested positive) and provided more reproductive choice options compared with no screening, but were associated with higher costs. While all screening strategies had similar values for health outcomes, when comparing all strategies together, universal screening with standard panels was the most cost-effective strategy for both preconception and prenatal periods. The incremental cost-effectiveness ratios (ICERs) of universal screening with standard panels compared with no screening in the preconception period were $29,106 per additional at-risk pregnancy detected and $367,731 per affected birth averted; the corresponding ICERs in the prenatal period were about $29,759 per additional at-risk pregnancy detected and $431,807 per affected birth averted.We estimated that publicly funding a universal carrier screening program in the preconception period over the next 5 years would require between $208 million and $491 million. Publicly funding a risk-based screening program in the preconception period over the next 5 years would require between $1.3 million and $2.7 million. Publicly funding a universal carrier screening program in the prenatal period over the next 5 years would require between $128 million and $305 million. Publicly funding a risk-based screening program in the prenatal period over the next 5 years would require between $0.8 million and $1.7 million. Accounting for treatment costs of the screened health conditions resulted in a decrease in the budget impact of universally provided carrier screening programs or cost savings for risk-based programs.Participants value the perceived potential positive impact of carrier screening programs such as medical benefits from early detection and treatment, information for reproductive decision-making, and the social benefit of awareness and preparation. There was a strong preference expressed for thorough, timely, unbiased information to allow for informed reproductive decision-making. Conclusions: Carrier screening for CF, FXS, hemoglobinopathies and thalassemia, and SMA is effective at identifying at-risk couples, and test results may impact preconception and reproductive decision-making.The cost-effectiveness and budget impact of carrier screening programs are uncertain for Ontario. Over the short term, carrier screening programs are associated with higher costs, and also higher chances of detecting at-risk pregnancies compared with no screening. The 5-year budget impact of publicly funding universal carrier screening programs is larger than that of risk-based programs. However, accounting for treatment costs of the screened health conditions results in a decrease in the total additional costs for universal carrier screening programs or in cost savings for risk-based programs.The people we spoke with who had sought out carrier screening valued the potential medical benefits of early detection and treatment, particularly the support and preparation for having a child with a potential genetic condition.

Prevalence of morbidities across the lifespan for adults with spinal muscular atrophy: a retrospective cohort study.

BACKGROUND: Recently approved treatments for spinal muscular atrophy (SMA) may shift clinical care priorities to secondary complications associated with SMA-related aging. To date, there is little knowledge about the natural history of morbidities across the adult lifespan for SMA. The objective of this study was to identify the prevalence and odds ratio (OR) of various morbidities among adults with vs. without SMA prior to SMA-related treatment. METHODS: This was a retrospective cohort study that accessed Medicare fee-for-service and commercial claims data from 01/01/2008-12/22/2016. Data from adults ≥ 18 years old with SMA and without SMA matched (1:200 case:control) on demographics, region, and study entry year were included. The prevalence of 30 morbidities across physiologic systems (e.g., cardiovascular, metabolic, musculoskeletal, urinary) and mental health disorders was examined. Age- and sex-adjusted OR was estimated using logistic regression for each morbidity and effect modification by age and sex was tested. RESULTS: There were 2,427 adults with SMA (mean [SD] age, 59.7 [17.4] years; 49.0% female) and 484,528 matched adults without SMA. Adults with vs. without SMA had a higher prevalence and adjusted OR of all 30 morbidities, ranging from OR = 1.61 (95% CI = 1.45-1.80) for hypothyroidism to OR = 7.80 (95% CI = 7.10-8.57) for fluid/electrolyte disorders. There was effect modification by age for 24 morbidities. The OR was highest for the youngest age group (18-40 years; OR range, 2.38 to 117.7; all P < 0.05) and declined with older age groups, but still remained significantly elevated in the oldest age group (≥ 75 years; OR range, 1.30 to 5.96; all P < 0.05). CONCLUSIONS: The limitations of this study are that evidence of morbidities were limited to diagnostic claims and information on SMA type and symptoms or onset were not available. In conclusion, adults with SMA had a higher and earlier prevalence of a variety of morbidities across physiological systems and mental health disorders.

Economic evaluation of Motor Neuron Diseases: a nationwide cross-sectional analysis in Germany.

BACKGROUND AND OBJECTIVES: Motor Neuron Diseases (MND) are rare diseases but have a high impact on affected individuals and society. This study aims to perform an economic evaluation of MND in Germany. METHODS: Primary patient-reported data were collected including individual impairment, the use of medical and non-medical resources, and self-rated Health-Related Quality of Life (HRQoL). Annual socio-economic costs per year as well as Quality-Adjusted Life Years (QALYs) were calculated. RESULTS: 404 patients with a diagnosis of Amyotrophic Lateral Sclerosis (ALS), Spinal Muscular Atrophy (SMA) or Hereditary Spastic Paraplegia (HSP) were enrolled. Total annual costs per patient were estimated at 83,060€ in ALS, 206,856€ in SMA and 27,074€ in HSP. The main cost drivers were informal care (all MND) and disease-modifying treatments (SMA). Self-reported HRQoL was best in patients with HSP (mean EuroQoL Five Dimension Five Level (EQ-5D-5L) index value 0.67) and lowest in SMA patients (mean EQ-5D-5L index value 0.39). QALYs for patients with ALS were estimated to be 1.89 QALYs, 23.08 for patients with HSP and 14.97 for patients with SMA, respectively. Cost-utilities were estimated as follows: 138,960€/QALY for ALS, 525,033€/QALY for SMA, and 49,573€/QALY for HSP. The main predictors of the high cost of illness and low HRQoL were disease progression and loss of individual autonomy. CONCLUSION: As loss of individual autonomy was the main cost predictor, therapeutic and supportive measures to maintain this autonomy may contribute to reducing high personal burden and also long-term costs, e.g., care dependency and absenteeism from work.

Effect of the COVID-19 pandemic on outpatient care and rehabilitation in neuromuscular clinical practice in Japan: a health insurance claims database analysis.

OBJECTIVES: To evaluate the impact of the COVID-19 pandemic on outpatient care in Japanese patients with neuromuscular diseases (NMDs). DESIGN: This retrospective cohort study included patients between January 2018 and February 2019; the follow-up period was divided into 'before COVID-19' (March 2019-February 2020) and 'during COVID-19' (March 2020-February 2021). SETTING: JMDC claims database study. PARTICIPANTS: Of the 10 655 557 patients identified, we included patients with spinal muscular atrophy (SMA; n=82), neuromyelitis optica (NMO; n=342), myasthenia gravis (MG; n=1347), Guillain-Barré syndrome (GBS; n=442) or autoimmune encephalitis/encephalopathy (AIE; n=133). Patients were required to have ≥1 month of data available, have a diagnosis of NMD during the enrolment period and be available for follow-up. PRIMARY AND SECONDARY OUTCOME MEASURES: We estimated the proportion of patients with >30% change in outpatient consultation and rehabilitation visits before versus during the COVID-19 pandemic. RESULTS: Small reductions in the proportion of patients with outpatient consultation/rehabilitation visits were observed before versus during the pandemic. Compared with before the pandemic, 30.4%, 27.8%, 28.7%, 49.4% and 50.0% of patients showed a >30% decrease in outpatient consultation visits and 58.6%, 75.0%, 50.0%, 76.3% and 84.6% showed a >30% decrease in outpatient rehabilitation visits during the pandemic for SMA, NMO, MG, GBS and AIE, respectively. The median change in the number of outpatient consultation visits per year before versus during pandemic was -1.0 day for all NMDs, and that in outpatient rehabilitation visits per year was -6.0, -5.5, -1.5, -6.5 and -9.0 days for SMA, NMO, MG, GBS and AIE, respectively. The reduction in outpatient rehabilitation visits was greater in the absence versus presence of a neurology specialist. CONCLUSIONS: Outpatient consultation and rehabilitation visits during the COVID-19 pandemic were affected in Japanese patients with NMDs. Longer-term evaluations are required to understand if these reductions in outpatient care would affect patient prognosis.

Development of an International SMA Bulbar Assessment for Inter-professional Administration.

BACKGROUND: Progressive weakness can affect bulbar muscles in individuals with moderate to severe forms of spinal muscular atrophy (SMA). The paucity of standardized, valid bulbar assessments capturing clinically significant deficits in SMA impedes the ability to monitor function, facilitate intervention, or detect treatment response. OBJECTIVE: To fill this void, an international multidisciplinary team gathered to develop an agreed upon consensus-derived assessment of bulbar function in SMA for inter-professional administration to enhance our ability to monitor disease progression, support clinical management, and evaluate treatment effects. METHODS: Fifty-six international clinicians experienced in SMA were invited and engaged using the Delphi method over multiple rounds of web-based surveys to establish consensus. RESULTS: Serial virtual meetings occurred with 42 clinicians (21 speech and language therapists, 11 physical therapists, 5 neurologists, 4 occupational therapists, and 1 dentist). Seventy-two validated assessments of bulbar function were identified for potential relevance to individuals with SMA (32 accessible objective, 11 inaccessible objective, 29 patient-reported outcomes). Delphi survey rounds (n = 11, 15, 15) achieved consensus on individual items with relevance and wording discussed. Key aspects of bulbar function identified included: oral intake status, oral facial structure and motor strength, swallowing physiology, voice & speech, and fatigability. CONCLUSIONS: Multidisciplinary clinicians with expertise in bulbar function and SMA used Delphi methodology to reach consensus on assessments/items considered relevant for SMA across all age groups. Future steps include piloting the new scale moving towards validation/reliability. This work supports the advancement of assessing bulbar function in children and adults with SMA by a variety of professionals.
