Publication helps establish the efficacy and safety profile of of CTx-1301, reinforcing the potential of Cingulate’s Precision Timed Release™ platform technology

KANSAS CITY, Kan., July 30, 2026 (GLOBE NEWSWIRE) -- Cingulate Inc. (NASDAQ: CING), a biopharmaceutical company utilizing its proprietary Precision Timed Release™ (PTR™) drug delivery platform technology to build and advance a pipeline of next-generation pharmaceutical products, announced today that Phase 3 clinical trial results for its lead asset, CTx-1301 (dexmethylphenidate HCl), for the treatment of attention-deficit/hyperactivity disorder (ADHD), have been published in the Journal of Child and Adolescent Psychopharmacology and are now available through open access.

The peer-reviewed publication helps establish the efficacy and safety profile of CTx-1301 and reinforces the potential of Cingulate’s Precision Timed Release™ (PTR™) platform technology, as the Company advances its lead asset toward potential regulatory approval and commercialization. The manuscript represents an important addition to the scientific literature supporting next-generation ADHD treatments designed to address ongoing challenges associated with symptom control, dosing convenience, and treatment consistency.

“Publication of these Phase 3 results in a respected peer-reviewed journal represents an important milestone for Cingulate and reflects the rigorous science behind our Precision Timed Release™ (PTR™) platform,” said Cingulate Chairman and CEO Shane J. Schaffer. “The independent review and publication of our clinical data provide additional scientific support for CTx-1301 as we continue advancing this potential new treatment option for individuals living with ADHD and their families. We thank our clinical investigators, research partners, and the patients and families who participated in this study. Their contributions made this work possible.”

Ann Childress, M.D., lead investigator for the Phase 3 trial, stated, “The study demonstrated clinically meaningful improvements in ADHD symptoms while maintaining a favorable safety profile, and the publication of these results provides clinicians with expert-reviewed evidence supporting CTx-1301’s potential as a once-daily treatment option.”

In the Phase 3 study, all three CTx-1301 dose groups demonstrated improvements compared with placebo in the primary efficacy endpoint, measured by change from baseline in ADHD Rating Scale-5 (ADHD-RS-5) scores at Week 5. The p-values for the 18.75 mg, 25 mg, and 37.5 mg dose groups were 0.018, 0.011, and 0.001, respectively. The placebo-adjusted effect sizes were 0.737, 0.782, and 1.185, respectively, with an overall mean effect size of 0.901 across the study population.

“Beyond achieving statistical significance, the magnitude of the treatment effect observed in the Phase 3 study is an important measure of the potential clinical impact of CTx-1301,” said Raul Silva, M.D., Chief Science Officer of Cingulate. “Effect size helps quantify how much improvement was observed compared with placebo, providing context on the strength of the treatment response. The effect sizes observed across all three CTx-1301 dose groups demonstrate a meaningful separation from placebo and provide additional confidence in the potential of the Precision Timed Release™ platform to deliver consistent, clinically relevant symptom improvement with once-daily dosing.”

The full publication, “Efficacy and Safety of Trimodal Dexmethylphenidate (CTx-1301) in Children and Adolescents with Attention-Deficit/Hyperactivity Disorder: Results From a Phase 3, Randomized, Double-Blind, Fixed-Dose, Placebo-Controlled Trial," is available at journals.sagepub.com.

About the Phase 3 Children/Adolescent Fixed Dose Study (CTx-1301-005)

• A double-blind, randomized, placebo-controlled, multi-center, fixed-dose (doses 18.75mg, 25mg and 37.5mg), parallel-group efficacy and safety study in a pediatric population (6-17) with ADHD
• The study was comprised of a screening period, a double-blind randomized phase, and a safety follow-up visit
• The primary endpoint of the trial was mean change in ADHD Rating Scale 5 (ADHD-RS-5) scores from baseline (pre-dose) at Visit 2 to ADHD-RS-5 scores at Visit 8
• The secondary endpoint was mean change in Clinical Global Impression - Severity (CGI-S) scores within the same time frame. Multiple safety and pharmacokinetic analyses were also measured

About Attention Deficit/Hyperactivity Disorder (ADHD)
ADHD is a chronic neurobiological and developmental disorder that affects millions of children and often continues into adulthood. The estimated market size of the US ADHD market is approximately 100 million annual prescriptions. The condition is marked by an ongoing pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development. In the U.S., over 20 million patients have been diagnosed with ADHD. Among this group, 12 million are adults and over 8 million are under the age of 17. According to the CDC, just 53.6 percent of all children and teens with ADHD reported they were actively treating their symptoms with medication in 2022, with 65-90 percent demonstrating clinical ADHD symptoms that persist into adulthood.

About CTx-1301
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.

About Precision Timed Release™ (PTR™) Platform Technology
Cingulate is developing ADHD and anxiety disorder product candidates capable of achieving true once-daily dosing using Cingulate’s innovative PTR drug delivery platform technology. It incorporates a proprietary Erosion Barrier Layer (EBL) providing control of drug release at precise, pre-defined times with no release of drug prior to the intended release. The EBL technology is enrobed around a drug-containing core to give a tablet-in-tablet dose form. It is designed to erode at a controlled rate until eventually the drug is released from the core tablet. The EBL formulation, Oralogik™, is licensed from BDD Pharma. Cingulate intends to utilize its PTR technology to expand and augment its clinical-stage pipeline by identifying and developing additional product candidates in other therapeutic areas in addition to Anxiety and ADHD where one or more active pharmaceutical ingredients need to be delivered several times a day at specific, predefined time intervals and released in a manner that would offer significant improvement over existing therapies.
