• •3. Hospitalization in a psychiatric or mental health facility (For example \[e.g.\], psychiatric hospital, inpatient ward) at screening or within 3 months prior to screening.
• •4. Any concurrent or unstable medical condition that, in the investigator's judgment, could interfere with study conduct, confound interpretation of study data, or pose an undue risk to the participant's safety. Includes but is not limited to:
• •1. Malignancy within the past 2 years, except for adequately treated non-melanotic skin cancer, localized prostate cancer or cervical cancer in situ (other non-metastatic malignancies may be allowed with medical monitor approval).
• •2. Hematologic, endocrine, metabolic, cardiovascular, pulmonary, renal, hepatic, gastrointestinal, or neurologic disorders that are unstable or progressive.
• •3. Cardiovascular examples: three documented episodes of blood pressure greater than (\>)185/100 millimeters of mercury (mmHg), unstable ischemic heart disease, dilated cardiomyopathy, unstable valvular disease, cardiac conduction abnormalities, or bradycardia (participants will be excluded if resting (awake) heart rate (HR) less than (\<) 50 beats per minute (bpm) confirmed on repeat, or any symptomatic bradycardia.
• •5. Current active clinical diagnosis of delirium, psychosis or psychotic disorder, per Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria.
• •6. Active major depression requiring initiation or recent change of antidepressant therapy within 2 months prior to Screening.
• •7. Active symptoms of diarrhea, nausea, vomiting, or abdominal pain/discomfort or any Gastrointestinal (GI) condition that may impact IP absorption, e.g. gastric bypass surgery during screening or scheduled or prn medications to treat these conditions (e.g., loperamide, ondansetron, antispasmodic drugs).
• •8. History of seizure disorder, anorexia nervosa, or bulimia.

• •10. Known hypersensitivity or contraindication to Zunveyl® or galantamine-containing products.
• •11. Use of an investigational drug or device for neuropsychiatric symptoms within 30 days or 5 half-lives, whichever is longer prior to Baseline.
• •12. Life expectancy \<12 months, or a hospice/palliative plan of care inconsistent with study participation.
• •13. Any medical, neurological, or psychiatric condition that, in the investigator's judgment, may place the participant at risk, interfere with assessments, or compromise study participation.
• •14. Any participant currently receiving or who has ever received Zunveyl®.
• •15. Weight loss of \>10 in the 6-month period prior to screening.
• •16. Any planned general surgery during the duration of the study.
• •17. History of Stevens-Johnson Syndrome (TENS).
• •18. Significantly abnormal labs including Estimated Glomerular Filtration Rate (eGFR) \<10 or Liver function Tests (LFTs) \>2\*Upper Limit of Normal (ULN).

Concomitant medications that cannot be stopped including strong Cytochrome P450 (CYP) inhibitors/inducers of 3A4 or 2D6 or a high anticholinergic burden defined as an Anticholinergic Cognitive Burden (ACB) score \> 3 within 28 days prior to baseline. Any new neuropsychiatric medication that would need to be initiated during the study.
