The schedule of assessments (SOAs) carry over seamlessly for the cohort from studies done while treated with nusinersen and continue to track the most informative outcomes from that trial (e.g. nine hole peg test and grip strength), while adding the Box and Block Test (BBT) as an additional measure of upper limb endurance and function.', 'detailedDescription': 'Risdiplam is an orally bioavailable small molecule that distributes into the central nervous system (CNS) and peripheral tissues where it modifies SMN2 pre-mRNA splicing and increases tissue SMN protein levels. It was approved by the U.S. Food and Drug Administration for all SMA patients older than 2 months of age in August 2020.\n\nClinical trial data prompted us to consider risdiplam a reasonable alternative to nusinersen administered intrathecally or by subcutaneous intrathecal catheter (SIC) for patients with more advanced SMA. Considered within this clinical context, risdiplam presents a significant advantage by eliminating the risks of mechanical failure, intrathecal bleeding, and CNS infection associated with the SIC device. The schedule of assessments (SOAs) used in this cohort during the previous three-year period as part of a nusinersen study provide us with an established framework for data collection. Thus, the overall clinical experience with risdiplam as compared to nusinersen can be assessed using a prospective, crossover design in a real-world setting.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '35 Years', 'minimumAge': '2 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Biallelic SMN1 deletions\n* 3 or 4 copies of SMN2\n* Prior treatment with nusinersen for a minimum of 22 months\n\nExclusion Criteria:\n\n* Prior treatment with SMN gene replacement therapy\n* Prior exposure to another investigational agent.\n* Confounding neuromuscular disorder other than SMA'}, 'identificationModule': {'nctId': 'NCT05522361', 'acronym': 'RISE', 'briefTitle': 'Risdiplam in Patients With Spinal Muscular Atrophy Previously Treated With Nusinersen', 'organization': {'class': 'OTHER', 'fullName': 'Clinic for Special Children'}, 'officialTitle': 'Risdiplam Exchange in Patients With Spinal Muscular Atrophy (SMA) Previously and Exclusively Treated With Nusinersen', 'orgStudyIdInfo': {'id': 'RISE'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Open-label crossover', 'description': 'Participants crossover to 36 months of open-label risdiplam mono therapy following a comparable period of nusinersen treatment.', 'interventionNames': ['Drug: Risdiplam']}], 'interventions': [{'name': 'Risdiplam', 'type': 'DRUG', 'description': 'administered to participants per product label insert', 'armGroupLabels': ['Open-label crossover']}]}, 'contactsLocationsModule': {'locations': [{'zip': '17579', 'city': 'Strasburg', 'state': 'Pennsylvania', 'country': 'United States', 'facility': 'Clinic for Special Children', 'geoPoint': {'lat': 39.98316, 'lon': -76.18412}}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Clinic for Special Children', 'class': 'OTHER'}, 'collaborators': [{'name': 'Genentech, Inc.', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Medical Director', 'investigatorFullName': 'Kevin A.
