Beschreibung
Inclusion Criteria:
- Male or female pediatric participants with Phelan-McDermid syndrome ages 3 to 12 years (inclusive) at the time of signing the informed consent for the antecedent study.
- Participant must have completed all applicable study visits for the antecedent study in which they participated.
- Body weight ≥ 10 kg at Screening/Baseline.
- Participants with a PMSA-S overall score ≥ 3 at the Screening and Baseline visits.
- Not actively undergoing regression or loss of skills.
Exclusion Criteria:
- Use of exclusionary medication or unstable treatment regimens of acceptable concomitant medications as required by the protocol.
- Participants with seizures must be controlled on no more than 2 anticonvulsant medications (not counting rescue medications).
- Psychotropic medications or any other medication used for a chronic illness (not including antibiotics, pain relievers, anti-diarrheals, and laxatives) with doses and dosing regimen that have not been stable for at least 4 weeks before Screening. If the treatment was discontinued, the discontinuation must have occurred no fewer than 2 weeks before the start of Screening.
- Any intercurrent seizures in the past 6 months and /or more than 1 seizure in the past 12 months. •A single febrile seizure in the 6 months prior to screening is allowable if no rescue medication was required.
