Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to explore the preliminary safety and effectiveness of the digital therapeutic device 'NDTx-02' in supporting improvements of executive function in children and adolescents diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) or Autism Spectrum Disorder (ASD).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This pilot clinical trial aims to evaluate the preliminary safety and effectiveness of NDTx-02 in combination with Treatment-As-Usual (TAU) compared with TAU alone (waitlist control).

The study will employ a randomized waitlist-control design, in which participants will be assigned to either experimental group (immediate intervention) or waitlist control group (delayed intervention) with a 1:1 ratio.

* Experimental group (immediate intervention): NDTx-02 + TAU for the first 6 weeks (stage 1), followed by TAU only for the following 6 weeks (stage 2).
* Waitlist control group (delayed intervention): TAU only during the first 6 weeks (stage 1), followed by NDTx-02 + TAU for the following 6 weeks (stage 2).

Efficacy will be assessed using the K-BRIEF-2, K-VABS-II, K-ARS-5, KAT, WMT, C-TMT, Stroop Color and Word Test Children's Version, Digit Span test, CGI-S, and CGI-I.

The primary efficacy analysis will compare the experimental group and the waitlist control group during Stage 1 (weeks 0-6). The delayed intervention period (Stage 2) will be analyzed as secondary/exploratory.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Children and adolescents aged 5 to 12 years at the time of screening
* Diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) or Autism Spectrum Disorder (ASD)\* by a psychiatrist according to DSM-5 diagnostic criteria

\*For ASD, diagnosis can be supported by the Autism Diagnostic Interview-Revised (ADI-R) or the Autism Diagnostic Observation Schedule (ADOS), either version 1 or 2
* Full-Scale Intelligence Quotient (FSIQ) of 65 or higher
* Able to use the 'NDTx-02' installed on a tablet, alone or with the assistance of a guardian
* Able to comply with the recommended application schedule for the investigational device (6 weeks, 30 sessions, 5 times per week)
* Agree not to add or change any treatment/education/rehabilitation programs or medications, including Applied Behavior Analysis (ABA) or cognitive therapy, during the study period (continuation of pre-existing TAU \[Treatment-As-Usual\] is allowed)
* Participant and parent (or legal guardian) voluntarily decide to join the trial and provide written informed consent
* Participants willing to comply with the clinical trial procedures

Exclusion Criteria

* A risk of clinically significant behavioral problems, emotion regulation problems, psychotic symptoms, self-harm, or other harm at a level that affects the treatment process
* Severe acute/chronic medical or mental illness
* Serious trauma or surgery performed within 4 weeks before the screening date
* Participants with other disabilities such as severe neurological diseases (e.g. brain lesions, mental disorders, etc.)
* Participants who are currently participating in another clinical trial or have participated in another clinical trial within 30 days before the screening date
* Change in the dosage or regimen of medications that may significantly affect cognitive function within 4 weeks prior to the baseline visit
* Change in participation in treatment/education/rehabilitation programs that may significantly affect cognitive function within 4 weeks prior to the baseline visit
* Participation in a clinical trial of, or prior experience using, cognitive improvement or daily living improvement software within 12 weeks prior to the baseline visit
* In other cases where the investigator determines that participation in the clinical trial is inappropriate due to ethical reasons or the possibility of influencing the results of the clinical trial
