Male subjects with female partners must agree at Screening to remain abstinent or agree to use an effective and medically acceptable form of birth control from Screening to 90 days after the last dose of study drug. Subject must be in general good health defined as absence of any clinically relevant abnormalities as determined by the Investigator based on physical and neurological examinations, vital signs, ECGs, medical history, and laboratory values (hematology, chemistry, or urinalysis) at Screening. If any of the exams or values are not within the laboratory reference range, the Investigator must review range and determine if clinically relevant. If clinically relevant, the subject is not eligible for the study. Subject's intellectual function is at an appropriate level, as deemed by the Investigator. Subjects need to be able to perform at least the basic level of problems on the PERMP pre-test with at least 10 questions answered correctly per page or 2 minutes performed at Visit 2. Subject must meet Diagnostic and Statistical Manual of Mental Disorders - Fifth Edition (DSM-5) criteria for the primary diagnosis of ADHD for any of the three presentations (combined, inattentive, or hyperactive/impulsive presentation) upon clinical evaluation and confirmed by the Mini International Neuropsychiatric Interview for Attention Deficit/Hyperactivity Disorder - Adults (MINI). Subject must score 24 or higher on the Adult ADHD Investigator Rating Scale (AISRS) at the Screening visit (Visit 1) and Baseline visit (Visit 2) if no ADHD medication washout is required. For subjects requiring washout of ADHD medications, this criterion refers to a score following washout at the Baseline visit (Visit 2). Subject must have a score of 4 (moderately ill) or higher on the clinician-administrated Clinical Global Impressions-Severity (CGI-S) scale at Screening. For subjects requiring washout of ADHD medications, this criterion refers to a score at the Baseline visit (Visit 2). Subject must be able and willing to wash out of all stimulant ADHD medications (except study drug as indicated per protocol), including herbal medication, from 5 days prior to the start of the dose-optimization phase and for the duration of the entire study, defined as completion of the safety follow-up visit. Additionally, subject must be able and willing to wash out from all non-stimulant ADHD medications 21 days prior to the start of the dose optimization phase and for the duration of the entire study, defined as completion of the safety follow-up visit. Subject must be able to read, write, speak, and understand English and be able to communicate with the Investigator and study coordinator in a satisfactory fashion and complete any study-related materials. Subject must plan to be available for the entire duration of the study. Exclusion Criteria: If female and of child-bearing potential, the subject must not be pregnant or breastfeeding at any time during the study or for 30 days following the completion of the study. If of child-bearing potential, urine hCG tests will be administered at protocol specified time points. Any positive pregnancy test during the study will exclude them from further participation in the study. Subject has any psychiatric diagnosis of bipolar I or II disorder, current major depressive disorder, conduct disorder, disruptive mood dysregulation disorder, intellectual disability, obsessive-compulsive disorder, eating disorder, anxiety disorder (including generalized anxiety disorder), any history of psychosis, autism spectrum disorder, Tourette's Syndrome, confirmed genetic disorder with cognitive and/or behavioral disturbances, or any other diagnosis/significant medical history that at the discretion of the Investigator excludes the subject from entry into the study. Subject has evidence of any chronic disease of the central nervous system (CNS) such as tumors, inflammation, seizure disorder, vascular disorder, potential CNS-related disorders that might occur in childhood, or history of persistent neurological symptoms related to a serious head injury. Subject has any clinically significant and/or unstable medical abnormality, chronic medical condition, persistent neurological symptoms, history of cardiovascular abnormality, abnormalities of respiratory, hepatic, gastrointestinal, renal, or any disorder or history of a condition that would impact or interfere with drug absorption, distribution, metabolism, or excretion during the study or may interfere with the participants ability to participate in the study. Subject has family history of early cardiovascular disease or sudden death. Subject has any history of attempted suicide or clinically significant suicidal ideation based on the Columbia Suicide Severity Rating Scale (C-SSRS) assessment, or answers "yes" to "Suicidal Ideation" item 4 or 5 in the past 3 years on the C-SSRS lifetime/recent assessment at Screening. Subject has history of seizures, excluding febrile seizures. Subject has a known primary sleep disorder (e.g., sleep apnea, narcolepsy, etc.) Subject has a history of moderate to severe hypertension or has a resting sitting systolic blood pressure greater than140 millimeters of mercury (mmHg) or diastolic blood pressure greater than 90 mmHg.

Subject has first-degree relatives (biological parent or sibling) with a history of schizophrenia, schizoaffective disorder, bipolar I disorder, or bipolar II disorder. Subject has history of substance abuse or shows evidence of substance or alcohol use disorder or has a positive urine alcohol or drug screen at Screening. Subjects with positive drug screens may be allowed to continue in the study if the result of the positive drug screen is from prescribed medications and the subject is willing to washout of the medication as required per protocol.

Subject anticipates a move outside the geographic range of the investigative site during the duration of the study period or plans on travel that would not allow compliance to the protocol during the study period. Subject is unsuitable in any other way to participate in the study, as determined by the Investigator. Subjects who are family members of the employees at the study center, of the investigator, or those with direct involvement in the proposed study under the direction of that investigator or study center. Subjects that live in the same household are not allowed to be in the same cohort. Eligibility Criteria: Subjects will be required to meet the following criteria at the end of the dose-optimization phase in order to be eligible for the double-blind, randomized treatment phase.

Outcomes

Primary Outcome Measures

The primary efficacy analysis will analyze the change in PERMP scores from Baseline (pre-dose) at Visit 8 to hour 16 at Visit 8.
The Permanent Product Measure of Performance (PERMP) is an objective, validated, skill-adjusted math test that measures attention in ADHD. The PERMP total score comprises the sum number of math problems attempted and the number of math problems answered correctly. A higher PERMP score indicates lower impairment.

Secondary Outcome Measures

Key secondary analysis will analyze the change in PERMP scores from baseline at each time point during the laboratory environment at Visit 8.

5. Study Description

Brief Summary
The goal of this clinical trial is to evaluate the efficacy and safety of CTx-1301 in adults with ADHD in a laboratory classroom setting.
Detailed Description
A single-center, dose-optimized, double-blind, randomized, placebo-controlled, parallel efficacy and safety laboratory classroom study with CTx-1301 in approximately 25 adults aged 18 to 55 years with ADHD. The study will be comprised of a screening period, a dose-optimization phase, a double-blind randomized phase, and a safety follow-up phase. Subjects will undergo a screening visit prior to entering a 5-week dose-optimization phase. During the dose-optimization phase subjects will have weekly visit and will be titrated to doses ranging between 25mg-50mg of CTx-1301. Eligible subjects will be randomized to their optimal dose or placebo in a 1:1 ratio after completing a practice Adult Laboratory Classroom (ALC) visit with 4 PERMP assessments. Subjects will take their assigned/randomized dose over the following 7-day period. On the 7th day subjects will complete a full ALC visit. The duration of the full ALC visit will be approximately 17 hours. Subjects will have an in-clinic safety follow-up visit within 7 days after the full adult laboratory classroom visit.
