ION440 for MECP2 Syndrome
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called ION440 to assess its safety and tolerance in people with MECP2 Syndrome, a genetic condition that can cause developmental delays and other health issues. Participants will receive varying doses of ION440 to determine its effects on the body. The trial includes individuals diagnosed with MECP2 Syndrome who have been stable on their current medications for at least a month. As a Phase 1 trial, participants will be among the first to receive this treatment, aiding researchers in understanding its effects in people.
Will I have to stop taking my current medications?
The trial does not specify that you must stop taking your current medications. However, you need to be on stable doses of your current medications for at least 3 months before starting the trial, unless the investigator decides otherwise.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that ION440 is under study to determine its safety and effectiveness for treating MECP2 Duplication Syndrome. Initial studies focus on how well participants tolerate this treatment. As the study is in its early stages, researchers are still assessing its safety for humans. Early-phase trials mark the first time a treatment is tested in people, so information on side effects may be limited. Participants in these studies help researchers understand the treatment's safety and potential risks.12345
Why are researchers excited about this study treatment for MECP2 Syndrome?
Unlike the standard of care for MECP2 Syndrome, which often involves symptomatic treatments like physical therapy, occupational therapy, and medications for seizures or breathing issues, ION440 acts directly on the genetic level. Researchers are excited about ION440 because it is administered intrathecally, delivering the treatment directly into the spinal fluid, which could potentially offer more targeted and effective symptom management. By targeting the root genetic cause rather than just the symptoms, ION440 has the potential to provide a more comprehensive approach to managing this challenging condition.
What evidence suggests that ION440 could be an effective treatment for MECP2 Syndrome?
Research has shown that ION440 is under investigation as a potential treatment for MECP2 Duplication Syndrome. This condition occurs when an extra copy of the MECP2 gene leads to various developmental and neurological issues. ION440 aims to reduce the impact of this extra gene. Early results suggest it might help by normalizing the gene's activity. Although ION440 is not yet approved, initial research offers hope for those with this syndrome. In this trial, participants will receive different doses of ION440 or a sham procedure followed by ION440 to assess its effectiveness and safety. Additional studies are underway to evaluate its efficacy and safety further.12567
Are You a Good Fit for This Trial?
This trial is for children and adults with MECP2 Duplication Syndrome (MDS). Children must be aged 2-7, have a caregiver to consent and attend visits, while adults are eligible from ages 8-65. Participants need genetic confirmation of MDS and stable medication doses for at least 3 months.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Multiple Ascending Dose (MAD)

What Are the Treatments Tested in This Trial?
Interventions
- ION440
Trial Overview
The ATTUNE study tests the safety of ION440 when administered into the spinal fluid compared to a sham procedure. It aims to understand how the body handles ION440 and its effects on participants with MDS.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Placebo Group
Participants will receive ION440 intrathecally at Dose C during Part 1/MAD, followed by ION440 Dose C during Part 2/LTE.
Participants will receive ION440 intrathecally at Dose B during Part 1/MAD, followed by ION440 Dose B during Part 2/LTE.
Participants will receive ION440 intrathecally at Dose A during Part 1/MAD, followed by ION440 Dose A during Part 2/LTE.
During the Part 1/MAD period, a lumbar procedure (LP) will be performed at the same frequency as ION440 administration. Participants will not receive ITB injections during this period. It will be followed by the open-label Part 2/LTE period, where participants will receive ION440 at the same dose as their enrolled cohort (e.g. Dose A, Dose B or Dose C).
