About this study
A combination therapy of NRCT-101 with NRCT-202 is being developed for patients with ADHD.
Read the detailed description
A multi-center, randomized, double-blind, parallel, adaptive-design clinical trial to evaluate the safety and efficacy of co-administration of NRCT-101SR and low dose NRCT- 202XR compared to low or high dose of NRCT-202XR and placebo NRCT-101SR over a 6-week period in approximately 60 pediatric subjects (13-17 years of age) with ADHD.
Subjects' enrollment will be conducted in two stages.
In stage 1, subjects are planned to be randomized to one of the following two arms (1:1 ratio):
Arm 1: NRCT-101SR and low dose NRCT-202XR Arm 2: NRCT-101SR placebo and high dose NRCT-202XR
In stage 2, a third study arm will be added (Arm 3 - NRCT-101SR placebo and low dose NRCT-202XR.
The study population will include male and female subjects (sex assigned at birth) of all races/ethnicities with ADHD.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing NRCT-101SR, NRCT-202XR in people with ADHD, run by Neurocentria, Inc. at 5 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 15 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Slow enrollment). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
CGI-S (time frame: 6 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jan 2026; AzTrials last refreshed its copy on 29 Oct 2026.
