Cingulate Presents Positive Phase 3 Results for CTx-1301 Demonstrating Statistically Significant Efficacy and Entire Active-Day Symptom Control
Once-daily formulation of dexmethylphenidate achieved primary endpoint (p < 0.001) with consistent symptom relief up to 12 hours post-dose
KANSAS CITY, Kan., Oct. 28, 2025 (GLOBE NEWSWIRE) -- Cingulate Inc. (NASDAQ: CING), a biopharmaceutical company developing and advancing a pipeline of next-generation pharmaceutical products utilizing its proprietary Precision Timed Release™ (PTR™) drug-delivery platform, announced today that the positive Phase 3 results from its pivotal trial of CTx-1301 (dexmethylphenidate HCl) in pediatric ADHD, were recently presented by Ann Childress, M.D., at the AACAP Annual Meeting in Chicago. CTx-1301 met its primary endpoint, demonstrating dose-dependent improvements on the ADHD ratings scale 5 (ADHD-RS-5), and Clinical Global Impression-Severity (CGI-S) scales, and demonstrated the ability to deliver symptom relief with the convenience of once-daily dosing.
In the randomized, double-blind, pediatric and adolescent, placebo-controlled study, CTx-1301 delivered rapid onset of effect and sustained efficacy through the evening hours. Safety and tolerability were consistent with the stimulant class, with no unexpected adverse events reported.
“In summary, CTx1301 demonstrated dose dependent efficacy in improving ADHD symptoms in children and adolescents. The 37.5mg dose demonstrated the largest effect size in symptom reduction and effect sizes were pretty substantial, considering this was a forced dose and not a dose optimization study,” Dr. Childress stated during the presentation. “The safety profile did not show anything that would be of concern, as it looks like other methylphenidates.”
ADHD represents a $23 billion global market, yet most treatments require two or more daily doses. CTx-1301 offers the potential for simpler once-daily management, which could translate to better adherence for patients and families. Cingulate’s commercial partnership with Indegene, a digital-first, life sciences commercialization company, is designed around a variable-cost structure that aligns commercial execution with growth milestones as the company approaches launch.
The New Drug Application for CTx-1301 was accepted by the FDA in October 2025, with a target PDUFA date of May 31, 2026. Cingulate also received a waiver of the standard PDUFA filing fee. Granted through the small business waiver provision of the Federal Food, Drug, and Cosmetic Act (FD&C Act), the waiver will save Cingulate approximately $4.3 million.
“These results demonstrate that CTx-1301 can deliver reliable symptom control for the entire active-day in a single dose — something families and clinicians have wanted for years. With this Phase 3 data in hand, we believe CTx-1301 is well positioned to become a next-generation treatment for ADHD as we move toward potential approval and launch in 2026,” said Raul Silva, M.D., Chief Science Officer of Cingulate.
The Company plans to share additional details from the Phase 3 study in upcoming scientific publications and investor communications.
Dr. Childress recently appeared on the “Unboxing Biotech” webcast with John Vandermosten, Senior Analyst for Zacks Investment Research, where she discussed the podium presentation and CTx-1301 data during a wide-ranging discussion about ADHD. The segment can be viewed here.
About Attention-Deficit/Hyperactivity Disorder (ADHD)
ADHD is a chronic neurodevelopmental disorder affecting an estimated 20 million individuals in the U.S., including approximately 8 million children and 12 million adults. The condition is characterized by inattention, hyperactivity, and impulsivity that impair academic, professional, and social functioning. Stimulant medications remain the gold-standard therapy; however, most currently available extended-release formulations require multiple doses per day and often fail to provide consistent coverage across the entire active day.

CTx-1301 (dexmethylphenidate HCl) is a once-daily, multi-core tablet utilizing Cingulate’s proprietary Precision Timed Release™ (PTR™) platform to deliver three precisely timed releases of active medication across the day. This design aims to provide rapid onset of effect and entire active-day duration. CTx-1301 is being evaluated for the treatment of ADHD under the FDA’s 505(b)(2) pathway.
