In this PIERRE-PK study, researchers will learn how the body processes nusinersen when it is given through the ThecaFlex DRx™ System, compared to when nusinersen is given by lumbar puncture (LP). The ThecaFlex DRx system is an investigational implantable medical device developed by Alcyone Therapeutics, Inc. It consists of a catheter, which is a flexible tube, connected to a port which is placed under the skin. Alcyone Therapeutics, Inc. has an ongoing study called PIERRE to test the ThecaFlex DRx system. Participants with spinal muscular atrophy (SMA) in the PIERRE study may be enrolled in the PIERRE-PK study. The main objective of the PIERRE-PK study is to learn how the body processes nusinersen when given by the ThecaFlex DRx system compared to a lumbar puncture. The main questions researchers want to answer are: * What is the highest amount of nusinersen found in the blood after dosing? * How much nusinersen is found in the blood over the first 24 hours after dosing? The PIERRE-PK study will be done as follows: * Participants will be screened to check if they can join the study. The screening period will be up to 30 days for this study and may overlap with the PIERRE study. * Participants will receive a dose of nusinersen by lumbar puncture. * The ThecaFlex DRx system will be implanted after the lumbar puncture, as part of the PIERRE study. * Participants will receive a dose of nusinersen by the ThecaFlex DRx system, as part of the PIERRE study. * Researchers will take blood samples before and after each dose. The last blood sample will be taken 24 hours after the dose. * The total study duration for each participant in the PIERRE-PK study will be up to 5 months. This period will overlap with the participant's first 5 months in the PIERRE study.

Spinal Muscular Atrophy
Spinal cord stimulation (SCS) has shown remarkable efficacy in restoring motor function in people with spinal cord injury by recruiting afferent input to enhance the responsiveness of spared neural circuits to residual cortical inputs. This pilot will test if SCS can show evidence to improve motor deficits in people with Type 2, 3, or 4 spinal muscular atrophy (SMA). The investigators will enroll up to six subjects with Type 2, 3, or 4 SMA aged 16 or older that show quantifiable motor deficits of the upper body. The investigators will then implant the subjects with percutaneous, linear spinal leads near the cervical spinal cord for a period of up to 29 days. Although these leads are not optimized for motor function but rather for their clinically approved indication of treating pain, the investigators believe they provide a safe technology enabling our team to perform scientific measurement necessary to evaluate potential for effects of SCS in motor paralysis with SMA. After the end of the study, the leads will be explanted.
Spinal Muscular Atrophy, Spinal Muscular Atrophy Type 3, Spinal Muscular Atrophy Type II, Spinal Muscular Atrophy 4, SMA
This study will aim to assess the fertility status of men with Spinal Muscular Atrophy (SMA) not on disease-modifying therapies. Participants will: 1. Complete online questionnaires that will assess SMA diagnosis and disease burden, medical and surgical history, medication usage, and fertility status and perspectives. 2. Over the 3-month initial study baseline period participants will provide two separate ejaculates for semen analysis and a single determination of sperm quality using DNA fragmentation testing using home collection and subsequent shipment to a central laboratory. 3. Over the initial study baseline period of 3 months study participants will obtain a blood test to determine male reproductive hormone levels. During the 24-month study duration, participants will be requested to undergo a yearly semen analysis and complete online relevant questionnaires.
Fertility Issues
This global, retrospective, non-interventional, medical chart review (MCR), descriptive study collected patient-level data in regions outside the US. The study required a repeated data collection at follow-up dates from start of treatment with nusinersen, onasemnogene abeparvovec-xioi (OA), and/or risdiplam. At the start of data collection, the study team reached out to the health care providers (HCPs) involved in treating pediatric SMA patients for participating in this study. The physicians across the participating countries conducted a retrospective MCR of pediatric patients diagnosed with SMA who were treated with at least 1of the 3 novel disease-modifying treatments (DMTs): nusinersen, OA, and/or risdiplam. All health care encounters data i.e., emergency and inpatient admissions, surgery, and outpatient consultations of recruited patients, including their treatment with nusinersen, OA, and/or risdiplam, were abstracted to understand the treatment patterns as per routine clinical practice for SMA management globally. The first date of initial administration of 1 of the 3 target drugs was used as the "index date." Based on this, the record abstraction was performed through a retrospective MCR during the pre-index period, at index date and in the post-index period.

This study will focus on the pathophysiological underpinnings of reduced exercise capacity and fatigue in ambulatory patients with spinal muscular atrophy (SMA). There has been laboratory evidence to suggest that the molecular mechanisms underlying mitochondrial biogenesis may be vulnerable to survival motor neuron (SMN) protein deficiency. This is an observational, single visit study including 34 ambulatory SMA patients treated with SMN repletion therapies (risdiplam or nusinersen) for at least 6 months at enrollment.
Spinal Muscular Atrophy
Spinal cord stimulation (SCS) has shown remarkable efficacy in restoring motor function in people with spinal cord injury by recruiting afferent input to enhance the responsiveness of spared neural circuits to residual cortical inputs. This pilot will test if SCS can show evidence to improve motor deficits in people with type 3 or 4 spinal muscular atrophy (SMA). The investigators will enroll up to six subjects with Type 3 or 4 SMA aged 16 or older that show quantifiable motor deficits of the legs but are able to stand independently. The investigators will then implant the subjects with percutaneous, bilateral, linear spinal leads near the lumbar spinal cord for a period of up to 29 days. Although these leads are not optimized for motor function but rather for their clinically approved indication of treating pain, the investigators believe they provide a safe technology enabling our team to perform scientific measurement necessary to evaluate potential for effects of SCS in motor paralysis with SMA. After the end of the study, the leads will be explanted.

Risdiplam works by helping the body produce more survival motor neuron (SMN) protein throughout the body. This means fewer motor neurons - nerve cells that pass impulses from nerves to muscles to cause movement - are lost, which may improve how well muscles work in people with SMA. RO7204239 is an investigational anti-myostatin antibody that is designed to target myostatin. Myostatin plays an important role in the regulation of skeletal muscle size by controlling growth. Inhibiting myostatin may help muscles grow in size and strength. RO7204239 in combination with risdiplam, which is designed to increase the amount of SMN protein throughout the body, has the potential to further improve motor function and clinical outcomes for people living with SMA. This trial will study the safety and efficacy of RO7204239 in combination with risdiplam in patients with spinal muscular atrophy (SMA). The trial has two parts; Part 1 is the dose-finding part in SMA patients that are either ambulant (aged 2-10 years) or non-ambulant (aged 5-10 years) within separate cohorts, and Part 2 is the pivotal part in SMA patients aged 2-25 years that are ambulant.
Spinal Muscular Atrophy (SMA)
To evaluate the efficacy, safety and tolerability of intrathecal (IT) OAV101 in treatment naive patients with Type 2 spinal muscular atrophy (SMA) who are ≥ 2 to \< 18 years of age over a 15 month trial duration.
Type 2 Spinal Muscular Atrophy
In this study, researchers will learn more about the use of a higher dose of nusinersen (BIIB058) in participants with spinal muscular atrophy (SMA). This study will focus on teenagers and adults who are unable to walk on their own and who have previously taken another drug for SMA called risdiplam. The main goal of this study is to learn about the effect of high dose (HD) nusinersen on muscle and movement ability (motor function) in SMA. The main question that researchers want to answer is: - How do the scores of a movement test called the Revised Upper Limb Module change from the start of treatment? The Revised Upper Limb Module is a test used to measure a participant's ability to do specific tasks that involve their shoulders, arms, wrist, elbows, and hands. It measures the changes in their abilities over time. Researchers will also learn more about the safety of HD nusinersen. They will check participants for adverse events and changes in vital signs, heart tests, and laboratory tests including blood and urine tests. The study will be done as follows: * Participants will be screened to check if they can join the study. * After screening, participants will enter the Core Treatment period. * At the start of the Core Treatment period, they will receive 2 "loading" doses of nusinersen. These are 50 mg doses of nusinersen given 2 weeks apart. * Afterwards, they will continue to receive "maintenance" doses of nusinersen once every 4 months. These doses will be 28 mg. * The Core Treatment period will last about 2 years, with a follow-up visit 4 months after the last dose. * Participants who complete the Core Treatment period will have the option to continue receiving 28 mg of nusinersen in the Long-Term Extension (LTE) period for about 2 years. There will also be a follow-up visit 4 months after the last dose. * Nusinersen will be given through a lumbar puncture, which involves injecting the drug into the fluid around the spinal cord in the lower back. * In total, participants will have up to 18 study visits. They will also be called by researchers after each dose of nusinersen. * Participants will stay in the study for about 4.5 years if they complete both the Core Treatment and LTE periods.

Muscular Atrophy, Spinal
Spinal muscular atrophy (SMA) is a neurogenetic disorder caused by a loss or mutation in the survival motor neuron 1 gene (SMN1) on chromosome 5q13, which leads to reduced SMN protein levels and a selective dysfunction of motor neurons. SMA is an autosomal recessive, early childhood disease with an incidence of 1:10,000 live births. SMA is the leading cause of infant mortality due to genetic diseases. The purpose of this registry is to assess the long term outcomes of patients with SMA in the context of advances in treatment options and also to characterize and assess long-term safety and effectiveness of OAV-101.
