Overview of the TTX-381 study
The clinical trial for TTX-381 is studying people with ocular manifestations of Neuronal Ceroid Lipofuscinosis type 2, also called CLN2 disease.[1] The study is designed to evaluate safety and tolerability, which means the researchers want to learn how well the treatment can be used and what unwanted medical problems may happen.[1]
Who the trial is for
This study is for participants who have eye-related signs of CLN2 disease.[1] The trial includes 22 participants, so it is a small study that is meant to collect early information rather than answer every question about treatment benefit.[1]
Trial phase and study design
The study is a Phase 1/2 trial and is listed as an interventional study.[1] A Phase 1/2 trial is an early clinical study that usually looks first at safety, then begins to look for early signs of how a treatment performs.[1] In this trial, TTX-381 is given by subretinal use, which means it is placed under the retina, the light-sensitive layer at the back of the eye.[1]
What the researchers measure
The main outcome is ocular and overall adverse events and serious adverse events through Day 360.[1] An adverse event is any unwanted medical problem that happens during the study, while a serious adverse event is a more severe problem that may need hospital care or cause major harm.[1] By following participants through Day 360, the researchers are looking beyond the first treatment period to see what happens over time.[1]
Study status and size
The trial is currently Authorised, which means it has been approved to move forward.[1] The planned enrollment is 22 participants, showing that this is a focused study in a rare disease group.[1]
Simple explanations of key terms
Ocular manifestations means eye-related signs or problems caused by a disease.[1] Tolerability means how well people can handle a treatment, including whether side effects are manageable.[1] Interventional means the researchers give a treatment to study its effects, instead of only observing what happens naturally.[1]
