Announces Positive Top-Line Results from Phase 3 Adult Efficacy and Safety Trial of CTx-1301 (dexmethylphenidate) for ADHD
Indicative that CTx-1301 Provides Entire Active-Day Efficacy with Optimal Onset and Duration
CITY, KANSAS - July 11, 2023 - 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, today announced positive top-line results from its Phase 3 adult trial of its lead candidate, CTx-1301 (dexmethylphenidate),
a novel, investigational treatment being developed as a true, once-daily stimulant medication for attention deficit/hyperactivity disorder
(ADHD), upon approval from the U.S. Food and Drug Administration (FDA).
Childress, M.D., President, Center for Psychiatry and Behavior Medicine, Inc., and lead investigator in the Phase 3 CTx-1301-022 who
conducted the primary efficacy evaluations, AISRS and PERMP, stated, "From my observation the changes in the Adult ADHD Investigator
Symptom Rating Scale (AISRS; a scale that measures aspects of ADHD in adults) demonstrated a positive effect in subjects that received
CTx-1301 versus subjects that received placebo. I was also impressed with the overall improvement (change from baseline) of PERMP scores
in subjects who were randomized to CTx-1301 compared to placebo. Although a secondary endpoint, the established CGI scale for severity
of illness demonstrated clinical improvement in severity of illness. Overall, this in combination with the favorable safety profile,
bodes well for future Phase 3 studies."
Phase 3 CTx-1301-022 study (NCT05631626), which assessed efficacy and safety along with onset and duration of CTx-1301 in 21 adults
(age range: 18-55 years) with ADHD in an adult laboratory classroom setting, demonstrated a meaningful trend in improving ADHD symptoms
with a rapid onset of action and entire active-day duration. After a 5-week dose optimization period, subjects were either randomized
to their optimized dose of CTx-1301 or placebo. Subjects who were randomized to their optimized dose of CTx-1301 showed improvements
on the Permanent Product Measure of Performance (PERMP) (effect size 0.88 to 2.6; with an average of 1.79) compared to subjects randomized
overall effect size showed a trend toward significance with a p-value of 0.089 despite the modest sample size. A Meta-Analysis conducted
by Faraone and Glatt (Clinical Psychiatry 71:6 June 2010) using 11 published studies with long-acting stimulants in adults demonstrated
the average effect size to be 0.73 (approximate range 0.5 to 0.9). Subjects randomized to CTx-1301 demonstrated an effect size of 1.41
at 30 minutes and an effect size of 0.98 at 16 hours. Effect size represents the magnitude of a change in an outcome or the strength
of a relationship, the practical significance. The practical significance shows that the effect is large enough to be meaningful in the
real world. The larger the effect size the more meaningful the outcome.
addition, the secondary outcome using the Clinical Global Impression (CGI) Scale for severity of illness was associated with a decrease
in the severity of illness in subjects randomized to CTx-1301 compared to placebo. This is noteworthy as the purpose of this study was
to obtain estimates of effect size and it was not anticipated that significant treatment differences would be observed. CTX-1301 was
well tolerated; 9% of the subjects that were randomized to CT-x-1301 experienced treatment emergent adverse events (TEAEs), while 30%
of subjects that were randomized to placebo experienced TEAEs. Patient reported outcomes on the overall satisfaction with CTx-1301 compared
to subject's prior ADHD medication was favorable.
incredibly proud of our team for reaching this important clinical milestone. This Phase 3 trial is a major validation of what Cingulate
has set out to accomplish: create the only ADHD medication that overcomes the major unmet needs of available treatments with clear and
unmatched differentiation," said Shane J. Schaffer, PharmD, Chairman and CEO, Cingulate. "We believe that the analysis of
the full data set from this trial, along with completing our two upcoming trials in pediatric and adolescent patients, will allow us
to submit a New Drug Application for CTx-1301 by mid-2024, and most importantly, provide patients, physicians, and payors a product that
can provide exceptional ADHD treatment."
results from the Phase 3 CTx-1301-022 trial, including safety data and patient reported outcomes from a pre- and post-trial questionnaire,
are being submitted for presentation at upcoming medical meetings.
addition to the Phase 3 adult dose-optimization study, Cingulate plans to initiate its pivotal Phase 3 fixed-dose pediatric and adolescent
study this month and a dose-optimization onset and duration trial in pediatric patients in August 2023. Assuming positive clinical results
from the Phase 3 trials, Cingulate plans to submit a New Drug Application (NDA) for CTx-1301 in mid-2024 under the Section 505(b)(2)
Attention Deficit/Hyperactivity Disorder (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., approximately 6.4 million children and adolescents (11 percent) aged under the age of 18 have been diagnosed with ADHD. Among this
group, approximately 80 percent receive treatment, with 65-90 percent demonstrating clinical ADHD symptoms that persist into adulthood.
Adult ADHD prevalence is estimated at approximately 11 million patients (4.4 percent), almost double the size of the child and adolescent
segment combined, however, only an estimated 20 percent receive treatment.
the CTx-1301 Phase 3 Adult Dose-Optimization Study
first Phase 3 study (CTx-1301-022, NCT05631626) for CTx-1301 was a single-center, dose-optimized, double-blind, randomized, placebo-controlled,
parallel efficacy and safety adult laboratory classroom (ALC) study of CTx-1301 in 21 adults (age range: 18-55 years) with ADHD. The
study was comprised of a screening period, a dose-optimization phase, a double-blind randomized phase, and a seven-day safety follow-up
period. Subjects underwent a screening visit prior to entering a five-week dose-optimization phase.
the dose-optimization phase, subjects had weekly visits and were titrated to doses ranging between 25 mg and 50 mg of CTx-1301. Cingulate
utilized an ALC, which enabled it to facilitate repeated assessments over the course of a day to evaluate the onset and duration of efficacy
provided by CTx-1301. Eligible subjects were randomized to their optimal dose or placebo in a 1:1 ratio after completing a practice visit
with four Product Measure of Performance (PERMP) assessments. Subjects took their assigned/randomized dose over the following seven-day
period. On the seventh day, subjects completed a full ALC visit. The duration of the full ALC visit was approximately 17 hours. Subjects
had an in-clinic safety follow-up visit within seven days after the full ALC visit.
primary objective of CTx-1301-022 was to evaluate the efficacy of CTx-1301 compared to placebo in treating adults with ADHD in an ALC
study. Secondary objectives included determination of the onset and duration of clinical effect of CTx-1301 in treating ADHD in adults
in an ALC study and to determine safety and tolerability of CTx-1301 compared to placebo. The study also evaluated the quality and satisfaction
of prior medication to CTx-1301. The Phase 3 clinical trial program for CTx-1301 is being conducted in the U.S. and is instrumental for
the filing of the NDA to the FDA, expected in mid-2024.
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.
stimulants are the gold-standard of ADHD treatment due to their efficacy and safety, the long-standing challenge remains, providing patients
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.
Precision Timed Release (PTR ) Platform Technology
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.
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. To see Cingulate's PTR Platform click here.
