Investigation of Individualised Antisense Oligonucleotides (ASOs) in People With Unique Genetic Variants Causing Severely Debilitating, Life Threatening (SDLT) Central Nervous System (CNS) Conditions

Plain-language summary
This study is being conducted to evaluate individualised antisense oligonucleotides (ASOs) in participants with severely debilitating, life threatening (SDLT) central nervous system (CNS) conditions caused by unique genetic variants amenable to correction by an ASO.

Inclusion criteria
. The first participant receiving the individualised ASO, must be between 1 and 17 years of age (inclusive) at the time they receive their first ASO dose.
. The CNS condition is severely debilitating and/or life threatening.
. The identified genetic variant is unique.
. The identified genetic variant is considered the underlying cause of disease.
. The identified genetic variant is amenable to correction by an ASO.
. In the opinion of the investigator, the disease is at a stage that, if halted or slowed by treatment with the individualised ASO, has a reasonable chance to improve the participant's overall disease burden/impact on quality of life.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Incidence of Treatment-Emergent Adverse Events (Safety and Tolerability)
. In the opinion of the investigator, participant, and/or the participant's legally authorised representative, existing therapies have not resulted in meaningful benefit.
Exclusion criteria
. Known history or presence of any clinically significant hepatic, renal/genitourinary, gastrointestinal, cardiovascular, cerebrovascular, pulmonary, endocrine, immunological, musculoskeletal, neurological, psychiatric, dermatological, or haematological disease or condition other than the primary disease for which the individualised ASO is being developed that in the opinion of the Investigator could affect patient safety or interfere with study outcomes.
. Any contraindication to brain MRI scans.
. Any contraindication to sedation or anaesthesia.
. Any contraindication to lumbar punctures or IT infusions.
. Treatment with another ASO within 24 weeks of Screening.
. Treatment with any gene replacement therapy at any time.
