A Multiple Ascending Dose Study of BPN14770 in Healthy Young and Elderly Male or Female Subjects

1. Clinically significant abnormality, in the Investigator's judgement, indicated by the current hematology, biochemistry, or urinalysis tests, or from medical history, social history, vital signs, or physical examination.

2. Positive serology results for hepatitis B surface antigen (HbsAg), hepatitis C virus (HCV), or human immunodeficiency virus (HIV).

3. Marked hypotension (systolic blood pressure \[BP\] ˂90 mmHg or diastolic BP ˂50 mmHg) or hypertension (systolic BP ˃150 mmHg or diastolic BP ˃100 mmHg) based on supine and sitting values obtained at Screening, Day-1, or Day 1 predose. Out-of-range vital signs may be repeated once during each eligibility assessment (prior to the start of dosing on Day 1).

4. Marked bradycardia (heart rate ˂45 beats per minute \[bpm\]) or tachycardia (heart rate ˃110 bpm) based on supine ECG values obtained at Screening, Day -1, or Day 1 predose. Out-of-range vital signs may be repeated once at each eligibility assessment (prior to the start of dosing on Day 1).

5. Current or past history of significant (in the Investigator's judgement) cardiovascular, cerebrovascular, pulmonary, renal, or liver disease. Stable, well-controlled hypertension and hyperlipidemias are allowed (see Exclusion #10).

6. History of hematological disorders (e.g., thrombocytopenia) in the immediate family (i.e., parents and siblings).

7. Clinically important or significant conduction abnormalities on single ECG (including QTc interval ˃450 msec) or evidence or history of long QT syndrome. This exclusion applies to the ECGs obtained at Screening, Day -1, and Day 1 predose.

8. Current or past history of gastric or duodenal ulcers or other diseases of the gastrointestinal tract that could interfere with absorption of study drug. Note: Subjects with a history of appendectomy or cholecystectomy may be enrolled.

9. Active acute or chronic infectious diseases.

10. Unable to discontinue medications including psychotropic drugs, sedative antihistamines, or other centrally active medications \[e.g., CNS beta blockers\], and moderate to strong inhibitors or inducers of CYP3A4, CYP2D6, or other cytochromes). Other prescription or non-prescription drugs such as antihypertensive or cholesterol lowering drugs are allowed if, in the Investigator's judgement, they would not interfere with the test medication or the cognitive testing.

11. Any history of alcohol or drug abuse within the previous year prior to the Screening visit (per the current edition of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition: DSM-5), or regular (daily) consumption of alcohol exceeding two bottles of beer, or the equivalent amount of other forms of alcohol (1 serving = 12 oz beer, 5.0 oz wine, or 1.5 oz distilled spirits).

12. Any use of alcohol within 24 hours of admission into the study on Day -2.

13. Active smokers or tobacco users (e.g., chew and snuff) who are unable to discontinue tobacco use at least 3 months prior to admission to the study on Day -2 and refrain from using tobacco during the study treatment and evaluation period.

14. Inability or unwillingness to comply with the protocol, or likely inability to complete the study.

15. Participation in other clinical studies involving investigational drug within the previous 30 days prior to the Screening visit.

16. Donation of blood or blood products (including plasma) during the 8 weeks before the first administration of study drug on Day 1.

17. Positive screen for drugs of abuse or cotinine (at screen or upon admission), or a positive alcohol result (upon admission).

18. History of allergy to penicillin or sulfonamides, or any other clinically significant drug allergy that includes symptoms such as shortness of breath, rash, or edema.

19. Inability or unwillingness to perform the tasks necessary for the CogState Cognitive Function Assessments (elderly cohorts).

20. A suicidal ideation intensity score of 2 or higher per screening C-SSRS assessment and/or any suicidal behavior within the past 30 days.

Cognitive Testing Criteria:

Eligibility requirements for subjects in the elderly cohorts include successful completion of a computerized battery of CogState cognitive function assessments, including:

Detection Task (DET)

Identification Task (IDN)

One Card Learning Task (OCL)

One Back Task (ONB)

Continuous Paired Associate Learning (CPAL)

International Shopping List Task (ISLT)

Groton Maze Learning Test (GMLT)
