Eligibility criteria

  • Inclusion Criteria:
  • * Signed informed consent from parent(s) or legal guardian(s)
  • * Confirmed diagnosis of AS with genetic confirmation of full maternal ubiquitin-protein ligase E3A (UBE3A) gene deletion causing AS in the region of 15q11.2 q13
  • * Able to ambulate independently, or with assistance at the Screening Visit (note, a child whose primary means of mobility is by wheelchair is excluded from the study)
  • * Platelet count, prothrombin time / international normalized ratio, and partial thromboplastin time within 1.5x the normal limits at the Screening Visit
  • * Willing and able to comply with scheduled visits, drug administration plan, laboratory tests, and all study procedures, including LP procedure and tolerating anesthesia without intubation
  • * From the time of informed consent through to at least 6 months after the final dose of GTX-102, females of childbearing potential who are sexually active must use highly effective contraception or abstinence. Males are able to participate if they agree to remain abstinent (refrain from heterosexual intercourse) or use acceptable contraceptive methods during the study and for at least 3 months after the final dose of GTX-102
  • Exclusion Criteria:
  • * Any change in medications or diet/supplements intended to treat symptoms of AS (eg, sleeping aids, antiseizure medications, supplements, dietary change including ketogenic or low-glycemic index diet, other) within the month prior to the Screening Visit (excluding weight-based adjustments)
  • * Any condition that creates an increased risk of unsuccessful LP
  • * Current or expected concomitant use of drugs that increase the risk of bleeding (eg, heparin, low molecular weight heparin, platelet inhibitors)
  • * Known hypersensitivity to GTX-102 or its excipients that, in the judgment of the Investigator, places the subject at increased risk for adverse effects
  • * Presence or history of any condition that, in the view of the Investigator, would interfere with participation, pose undue risk, or would confound interpretation of results
  • * Any clinically significant cardiovascular, endocrine, hepatic, renal, pulmonary, gastrointestinal, neurologic, malignant, metabolic, psychiatric, or other condition or infection that, in the judgment of the Investigator, will pose a safety risk, make the subject unsuitable for participation in, and/or unable to complete the study procedures
  • * Any laboratory abnormality, that, in the Investigator's opinion, could adversely affect the safety of the subject, make it unlikely that the course of treatment or follow up would be completed, or impair the assessment of study result
  • * Pregnant or breastfeeding or planning to become pregnant (self or partner) at any time during the study
  • * Use of any investigational product or investigational medical device within 6 months or 5 half-lives prior to the Screening Visit or any prior use of gene therapy or ASO regardless of duration since last administration
  • * Concurrent participation in any study, including observational natural history studies
