No Clinical Safety or Efficacy Concerns Currently Identified

Agency Feedback Primarily Focused on CMC-Related Requests

Company Plans Prompt Response and Submission of Requested Information

Company is Well Capitalized with Nearly $30 Million Cash on Hand

KANSAS CITY, Kan., June 02, 2026 (GLOBE NEWSWIRE) -- Cingulate Inc. (NASDAQ:CING), a biopharmaceutical company utilizing its proprietary Precision Timed Release™ (PTR™) drug delivery platform to develop a pipeline of next-generation products, today announced that the U.S. Food and Drug Administration ("FDA") has issued a Complete Response Letter for its New Drug Application ("NDA") for CTx-1301 (dexmethylphenidate HCl) for the treatment of Attention Deficit/Hyperactivity Disorder (ADHD).

The response identified specific Chemistry, Manufacturing and Controls (CMC) information requests and did not raise any current concerns regarding the clinical safety or efficacy of CTx-1301. Cingulate expects a prompt submission to FDA of the requested information addressing issues raised.

"We are encouraged that the FDA's response was limited to specific information requests related to CMC and did not currently identify any issues related to the clinical safety or efficacy of CTx-1301," said Cingulate CEO Shane J. Schaffer. "Our immediate priority is to complete the CMC work already underway with our manufacturing partner; we believe the outstanding requests will be addressed quickly as we move efficiently toward resubmission. Importantly, we have nearly $30 million in cash reserves, which we believe provides sufficient capital to address the issues raised and execute on the resubmission process and continue pre-commercial activities into 2027."

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 U.S. 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. Current market trends demonstrate that adult ADHD prevalence is larger and growing faster than the child and adolescent segments combined.

About CTx-1301

CTx-1301 (dexmethylphenidate HCI) 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. In October 2025, Cingulate announced that the U.S. Food and Drug Administration (FDA) had accepted for review the New Drug Application (NDA) for CTx-1301 and had assigned a Prescription Drug User Fee Act (PDUFA) target action date of May 31, 2026. NDA acceptance signifies that the FDA has determined the submission is sufficiently complete to permit substantive review. NDA acceptance does not imply approval, nor does it guarantee any specific outcome or timing.

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.
