ADHD combo drug trial stops early – only 2 teens enrolled
NCT ID NCT06673368
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial tested a combination of two drugs, NRCT-101SR and NRCT-202XR, for teens with ADHD. The goal was to see if the combo could ease symptoms and reduce side effects better than one drug alone. However, the study was terminated early and only enrolled 2 participants, so no meaningful results were obtained.
