• NDA accepted under the FDA’s 505(b)(2) regulatory pathway
  
  

KANSAS CITY, Kan., Oct. 14, 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, today announced that the U.S. Food and Drug Administration (FDA) has accepted for review the New Drug Application (NDA) for CTx-1301 (dexmethylphenidate), the company’s lead candidate for the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD) in children and adults. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target action date of May 31, 2026. NDA acceptance signifies that the Agency has determined the submission is sufficiently complete to permit substantive review.

A Key Regulatory Milestone Under the 505(b)(2) Pathway
This marks a major regulatory inflection point for Cingulate and for the CTx-1301 program. CTx-1301 is being reviewed under the FDA’s 505(b)(2) regulatory pathway, which allows sponsors to reference existing data on previously approved active ingredients while demonstrating novel clinical benefit through a differentiated delivery mechanism. For Cingulate, this pathway offers the opportunity to leverage the extensive safety and efficacy data of dexmethylphenidate—an established and well-characterized stimulant—while enabling CTx-1301 to demonstrate rapid onset of effect and entire active-day duration through its proprietary multi-core PTR™ technology.

The NDA submission follows completion of adult and pediatric Phase 3 trials, completion of all FDA-requested studies, and a positive pre-NDA meeting in April 2025 confirming adequacy of the clinical and Chemistry, Manufacturing, and Controls (CMC) data packages for review. The FDA’s acceptance validates that Cingulate’s application meets the Agency’s standards for completeness and marks the beginning of the formal review period.

Clinical Results Support Differentiated Profile
In Phase 3 clinical trials, CTx-1301 improved ADHD signs and symptoms across multiple metrics in adult and pediatric patients (ages 6 years and older). Effect size measurements were large throughout the day, demonstrating that CTx-1301 provides a rapid onset of effect and sustained efficacy into the afternoon and evening, which may address long-standing gaps in ADHD management.

Key findings include:

• Adult dose-optimization study: Achieved clinically meaningful improvements on the Permanent Product Measure of Performance (PERMP) and Adult ADHD Investigator Symptom Rating Scale (AISRS).
• Pediatric fixed-dose study: Demonstrated dose-dependent improvements on the ADHD rating scale 5 (ADHD-RS-5), Clinical Global Impression–Improvement (CGI-I), and Clinical Global Impression–Severity (CGI-S) scales.
• Safety and tolerability: No serious treatment-emergent adverse events were reported across studies, and the tolerability profile was consistent with that of other long-acting methylphenidate products.
  

Management Commentary
“FDA acceptance of our NDA marks a defining milestone for Cingulate,” said Cingulate Executive Chairman Jay Roberts. “CTx-1301 was engineered to address the practical shortcomings of today’s stimulant therapies—multiple daily dosing, midday rebound, and adherence challenges—through a single, once-daily tablet. This milestone affirms the robustness of our clinical and regulatory strategy, and positions Cingulate to transition from a development-stage to a commercial-stage company in 2026, pending FDA approval of CTx-1301.”

Matt Brams, MD, Chief Medical Officer, added, “The acceptance of our NDA reflects the FDA’s recognition of the completeness of our submission and the strong body of evidence supporting CTx-1301’s efficacy, safety, and patient-centric design. Our adult and pediatric studies consistently demonstrated rapid symptom relief, sustained performance and the flexibility of dosing with or without food—attributes that we believe will resonate strongly with both physicians and patients.”

Launch Readiness
With the NDA now accepted, the FDA will conduct its full review of CTx-1301’s efficacy, safety, and overall risk–benefit profile. In parallel, Cingulate continues advancing key commercial readiness activities to ensure timely launch preparedness following potential approval. Through its exclusive manufacturing partnership with Bend Bio Sciences, Cingulate has completed process transfer and scale-up production using commercial-grade equipment, providing early validation and ensuring a reliable supply chain in preparation for launch.

On the commercial front, Cingulate’s partnership with Indegene delivers an integrated, AI-driven omnichannel platform that combines advanced analytics with targeted field engagement to optimize prescriber reach, payer access, and patient support. Early payer research indicates strong formulary receptivity for once-daily CTx-1301, underscoring the product’s alignment with key clinical and adherence priorities in ADHD care.

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.
