Une révolution est actuellement en cours dans le domaine des maladies neuromusculaires avec l’arrivée de nouvelles thérapies. L’amyotrophie spinale (SMA ou spinal muscular atrophy) est parmi les maladies pionnières de ce bouleversement thérapeutique. Le premier traitement approuvé et mis sur le marché en Europe et aux États-Unis est un oligonucléotide antisens dénommé nusinersen et commercialisé par le laboratoire Biogen sous le nom de Spinraza®. Il a comme indication les SMA de types 1, 2 et 3. La première injection de Spinraza® dans le cadre d’une ATU/EAP (Autorisation Temporaire d’Utilisation/Expanded Access Program ou programmes d’accès étendu) a été réalisée en France par le centre d’essais l-Motion. Les résultats des essais cliniques et des données de la littérature sur l’utilisation du nusinersen dans la SMA infantile sont discutés dans cette revue. Ces études rapportent une amélioration de la fonction motrice chez les patients SMA tous types confondus y compris les patients de type 3 [1, 2]. Une administration précoce du traitement s’accompagne d’une meilleure réponse clinique. Une meilleure compréhension de l’hétérogénéité génétique et clinique devient indispensable dans le monitoring et le suivi à long terme de ces patients.

Introduction. Spinal muscular atrophy is a severe neuromuscular disease characterized by rapid progression of muscle weakness and early death. Pathogenetic therapy with nusinersen can significantly change the course of the disease and enable the patient to acquire new skills. The study of the efficacy and safety of nusinersen therapy in patients with type 1 spinal muscular atrophy should be continued. The aim of the study was to assess the safety and efficacy of nusinersen therapy in patients with type 1 spinal muscular atrophy for 6 months as part of an expanded access program at federal and regional healthcare facilities. Materials and methods. Patients with type 1 spinal muscular atrophy received nusinersen therapy under the expanded access program (NCT02865109). Patients were evaluated before starting treatment and 6 months after starting treatment. Overall motor development and motor function was assessed using the Hammersmith Infant Neurological Status Scale Part 2 and the Philadelphia Pediatric Hospital Neonatal Motor Scale. Results. 41 children aged 6 to 38 months received nusinersen therapy between July 2019 and March 2020. At the time of analysis, all patients were alive and continued treatment. The average improvement on the Hammersmith Hospital Neurological Status Scale was 3.7 points after 6 months of therapy compared to baseline (n = 39, p <0.001). The mean improvement on the Children’s Hospital of Philadelphia Scale for the Diagnosis of Motor Function in Newborns was 9.8 after 6 months of therapy from baseline (n = 30, p <0.001). Conclusion. The efficacy and safety of nusinersen have been demonstrated in real clinical practice in Russia in the treatment of early-onset spinal muscular atrophy.

Ipilimumab (IPI) provides a ten-year overall survival in almost 20 % of selected patients participated in several phase II-III trials. However, the expanded access program (EAP) looks more like routine practice than like clinical trials& This is why the results of such application could be different. Here we present the long-term follow-up data of single center EAP. Ninety-six patients with disseminated melanoma progressing after at least one lines of drug therapy were included at the N.N. Petrov National Medical Research Center of Oncology. Sixty-seven (70 %) patients had stage IV M1c, 35 patients (36 %) had elevated LDH before initiating IPI therapy. All patients received IPI 3 mg / kg IV every 3 weeks for a maximum of 4 cycles. Totally, 320 cycles (mean - 3.3 per patient) were conducted. Grade 3-4 immuno-mediated adverse events (imAE) observed in 18 (19 %) patients. Three patients died of adverse events, possibly associated with ongoing therapy. The median time to progression was 3 (95 % CI, 2.4 to 3.5) mo., the median overall survival was 13 (95 % CI, 8.3 to17.6) mo. Previous immunotherapy with dendritic cell vaccines decreased the risk of death by 48 % (Log-rank p = 0.049). The wild type BRAF status increased three-year overall survival from 29 to 68 % (p = 0.042). Our data confirms long-term safety and efficacy of IPI in patients with pretreated disseminated melanoma in the close to real practice setting.

Abstract Background The 32-item Motor Function Measure (MFM32) is a clinician-reported outcome measure used to assess the functional abilities of individuals with neuromuscular diseases, including those with spinal muscular atrophy (SMA). This two-part study explored the relationship between the functional abilities assessed in the MFM32 and activities of daily living (ADLs) from the perspective of individuals with Type 2 and Type 3 (non-ambulant and ambulant) SMA and their caregivers through qualitative interviews and a quantitative online survey. Methods In-depth, semi-structured, qualitative interviews were conducted with individuals with SMA and caregivers from the US. Subsequently, a quantitative online survey was completed by individuals with SMA or their caregivers from France, Germany, Italy, Poland, Spain, Canada, the United States (US) and the UK. In both parts of the study, participants were asked to describe the ADLs considered to be related to the functional abilities assessed in the MFM32. Results from the qualitative interviews informed the content of the quantitative online survey. Results Qualitative interviews were conducted with 15 adult participants, and 217 participants completed the quantitative online survey. From the qualitative interviews, all of the functional abilities assessed in the patient-friendly MFM32 were deemed as related to one or more ADL. The specific ADLs that participants considered related to the patient-friendly MFM32 items could be grouped into 10 key ADL domains: dressing, mobility/transferring, self-care, self-feeding, reaching, picking up and holding objects, physical activity, writing and technology use, social contact/engagement, toileting and performing work/school activities. These results were confirmed by the quantitative online survey whereby the ADLs reported to be related to each patient-friendly MFM32 item were consistent and could be grouped into the same 10 ADL domains. Conclusion This study provides in-depth evidence from the patient/caregiver perspective supporting the relevance of the patient-friendly MFM32 items to the ADLs of individuals with Type 2 and Type 3 SMA.
