Trial overview
The clinical trial data shows one authorised study investigating Sodium Phosphate in people with Angelman Syndrome.[1] The study is described as a long-term extension trial, which means it continues research over a longer period after earlier study work.[1]
The brief summary says the trial aims to evaluate the long-term safety profile of GTX-102 in subjects with Angelman Syndrome.[1] The study also includes efficacy, meaning it looks at how well the treatment works over time.[1]
Study design and phase
This is an interventional study, which means researchers give study treatment and then observe the results.[1] The trial is in Phase 3, a later stage of clinical testing that usually includes more patients and focuses on safety and outcomes in a larger group.[1]
The study status is Authorised, and the planned enrollment is 98 participants.[1] This gives a sense of the trial size and that it is open for the research process described in the source data.[1]
Who can participate
The target population is patients with Angelman Syndrome.[1] The trial description does not list broader groups, so the study is focused on this specific condition.[1]
The intervention list includes study products given by intrathecal use, which means they are delivered into the space around the spinal cord.[1] The listed products are GTX-102, GTX/UX Diluent and Flush Solution, and ELLIOTTS B SOLUTION.[1]
What is being measured
The main endpoint is treatment-emergent adverse events and serious adverse events, including their frequency, severity, and relationship to the investigational product throughout the study.[1] In simple terms, the researchers want to know what medical problems happen after treatment starts, how serious they are, and whether they may be linked to the study treatment.[1]
This endpoint is important because it helps show the long-term safety profile of the treatment under study.[1] The source also states that the study is evaluating efficacy, but it does not give a detailed list of secondary outcomes in the trial data provided.[1]
Study treatments
The intervention section lists GTX-102, which is the investigational product named in the trial summary.[1] It also lists GTX/UX Diluent and Flush Solution and ELLIOTTS B SOLUTION as intrathecal study-related products.[1]
The source data does not provide a broader treatment comparison or placebo description, so the key point is that the study is following patients receiving these trial products as part of the research plan.[1]
Patient-friendly terms
Long-term extension trial means the study continues for a longer time so researchers can learn more about safety and results over time.[1] Efficacy means how well the treatment works for the condition being studied.[1]
Safety profile means the overall pattern of side effects or medical problems seen in the study.[1] Frequency means how often an event happens, and severity means how serious it is.[1]
Relationship to the investigational product means researchers judge whether a medical event may be caused by the study treatment.[1] These terms help patients understand what the trial team is watching during the study.[1]
