(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, today announced its financial results for the quarter ended March 31, 2025, and provided a clinical and business update. Highlights include the completion of the Pre-NDA meeting for CTx-1301 and grant received to accelerate development of CTx-2103. “The first quarter of 2025 has been a very constructive one for Cingulate,” stated Chairman and CEO Shane J. Schaffer. “We held a productive meeting with the FDA last month and remain on target to file an NDA in the middle of the year for our lead ADHD asset CTx-1301. The results announced from a food effect study of 50mg CTx-1301 – our largest dose – were positive and consistent with previous fed/fast data (25mg CTx-1301). We were also pleased to receive a $3 million grant of non-dilutive funding for the development of CTx-2103 for the treatment of anxiety, advancing our pipeline and illustrating the applicability of Cingulate’s PTR™ platform.” Cingulate Completes Pre-NDA Meeting with FDA to Discuss New Drug Application (NDA) for lead ADHD Asset CTx-1301 and Remains on Track to Submit the NDA Mid-2025 and Provides additional Clinical Updates On April 2, 2025, Cingulate completed its Pre-NDA meeting with the FDA to discuss the submission of an NDA for CTx-1301, its lead asset for the treatment of ADHD. This important milestone keeps Cingulate on track for a mid-2025 submission of the NDA for CTx-1301. In March 2025, Cingulate released Phase 3 safety data for CTx-1301, showing that the safety profile of CTx-1301 has remained consistent over the course of nine clinical trials. In late April 2025, Cingulate reported that the primary endpoint of the 50mg food effect study demonstrated that CTx-1301 can be taken with or without food. Cingulate Receives $3 million Grant from Private Foundation to Accelerate Development of Anxiety Asset CTx-2103 (buspirone) In April 2025, Cingulate received a $3 million grant to accelerate the development of CTx-2103 (buspirone) for the treatment of anxiety, to be paid in three installments of $1 million each. The first $1 million installment is expected to be received in May 2025, and will be used to fund a formulation study of CTx-2103. The second $1 million installment is expected to be received upon completion of a formulation study for CTx-2103 and the third $1 million installment is expected to be received upon completion of development batches required for the IND (Investigational New Drug Application) for CTx-2103. This grant is projected to cover the costs of the development of CTx-2103 through mid-2026, the targeted timing of the IND for CTx-2103. The foundation will receive a future royalty contingent on the commercialization of CTx-2103, beginning six months after the first commercial sale of CTx-2103, payable at $500,000 per quarter, with a maximum cumulative royalty of $3.5 million. CTx-2103 has the potential to be the first, once-daily formulation of buspirone, one of the most widely prescribed agents in the $5.5 billion US anxiety market ($11.6 billion globally). CTx-2103 also presents an alternative to the use of benzodiazepines and associated withdrawal and dependency issues. FIRST QUARTER RESULTS Cash Position: As of March 31, 2025, Cingulate had approximately $9.5 million in cash and cash equivalents, a $2.7 million decrease from December 31, 2024 and cash runway into the fourth quarter of 2025, beyond its targeted submission of the NDA for CTx-1301. Working Capital (current assets less current liabilities): As of March 31, 2025, Cingulate had approximately $4.9 million in working capital as compared to $7.7 million as of December 31, 2024. This decrease in working capital was primarily due to the use of cash to support operations, which was partially offset by capital raised during the quarter. Cingulate believes working capital is meaningful to investors as a measure of short-term financial health. R&D Expenses: Research and development expenses were $2.2 million for the three months ended March 31, 2025, an increase of $0.4 million or 23.0% from the three months ended March 31, 2024. This change was primarily the result of an increase in personnel expenses and development costs in the three months ended March 31, 2025 as compared to the same period in 2024. The increase in personnel costs was the result of the reinstatement of base salaries in September 2024 following salary reduction measures that were implemented in late 2023. Regulatory costs increased in the three months ended March 31, 2025 as compared to the same period in 2024 due to preparation for the pre-NDA meeting with the FDA G&A Expenses: G&A expenses were $1.5 million for the three months ended March 31, 2025, an increase of $0.3 million or 30.0% from the three months ended March 31, 2024. This is primarily the result of an increase in professional fees and personnel expenses. The increase in personnel costs is the result of reinstatement of base salaries in September 2024 as noted above. Net Loss: Net loss was $3.8 million for the three months ended March 31, 2025, compared to $3.0 million for the three months ended March 31, 2024. The increase in the net loss relates to increased development activity as well as the reinstatement of base salaries in September 2024. as noted above. 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 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 Cingulate’s lead candidate, CTx-1301, utilizes Cingulate’s proprietary PTR drug delivery platform to create a breakthrough, multi-core formulation of the active pharmaceutical ingredient dexmethylphenidate, a compound approved by the FDA for the treatment of ADHD. Dexmethylphenidate is part of the stimulant class of medicines and increases norepinephrine and dopamine activity in the brain to affect attention and behavior. While stimulants are the gold standard of ADHD treatment due to their efficacy and safety, the long-standing challenge continues to be providing patients with an entire active-day duration of action. CTx-1301 is designed to precisely deliver three releases of medication at the predefined time, ratio, and style of release to optimize patient care in one tablet. The result is a rapid onset and entire active-day efficacy, with the third dose being released around the time when other extended-release stimulant products begin to wear off. 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.

The company is developing other product candidates for anxiety disorders and attention deficit hyperactivity disorder. Credit: Pormezz/Shutterstock. US biopharmaceutical company Cingulate has announced the receipt of a $3m grant from a private foundation to expedite the development of a once-daily formulation of buspirone, CTx-2103, to treat anxiety. The multi-release tablet utilises the company’s precision timed release (PTR) drug delivery platform. The grant will be distributed in three $1m tranches, with the first payment scheduled for 1 May 2025 and the others contingent on achieving specific product development milestones. In return, the foundation will obtain future royalties from the tablet’s commercialisation, starting six months post the initial commercial sale. These royalties are set at $500,000 per quarter, with a $3.5m maximum cumulative royalty. The tablet is currently under study for the treatment of anxiety and related disorders. Buspirone, the active ingredient in CTx-2103, is an azapirone derivative and a 5-hydroxytryptamine receptor 1A (5-HT1A) partial agonist. It was introduced as the first non-benzodiazepine anxiolytic for generalised anxiety disorder. Buspirone’s advantage over other anxiolytic treatments is a potentially decreased side-effect profile, particularly the absence of risks related to physical dependence or withdrawal. Cingulate CEO and chairman Shane Schaffer stated: “We thank the foundation for this funding for the development of CTx-2103, which advances Cingulate’s pipeline and illustrates the applicability of our PTR platform. “Today, we are one step closer to providing the first once-daily medicine for the millions of patients worldwide who suffer from anxiety-related disorders, the most common mental health issue in America and around the world.” Cingulate’s PTR technology incorporates an erosion barrier layer (EBL), which controls the release of the drug at pre-defined times. The company is developing other product candidates for anxiety disorders and attention deficit hyperactivity disorder (ADHD) using its PTR platform. In 2023, Cingulate entered a joint commercialisation deal with Indegene, a life sciences commercialisation company, for ADHD therapy CTx-1301 (dexmethylphenidate).
