A Study to Assess Safety and Tolerability and to Explore Efficacy of NSC001 in Mild to Moderate Alzheimer's Disease

Exclusion criteria

• ✕. Long-acting benzodiazepines (e.g., valium), except for sedation prior to screening MRI scans for those participants requiring sedation and should not be administered within 24 hours prior to cognitive testing.
• ✕. Short/medium-acting benzodiazepines (e.g., alprazolam, lorazepam, oxazepam, temazepam) except if used chronically for sleep and on a stable dose for ≥4 weeks prior to screening and throughout the trial. May not be taken within 12 hours prior to cognitive testing.
• ✕. Sedating antihistamines if taken within 12 hours prior to cognitive testing (Non-sedating antihistamines \[e.g., fexofenadine, cetirizine\] are allowed).
• ✕. Anticonvulsants that have significant effects on cognition per the Investigator's opinion and/or anticonvulsants used for treatment of seizures. Anticonvulsants with limited cognitive effects, such as lamotrigine, pregabalin, levetiracetam for the treatment of pain, and other non-epilepsy indications are allowed if, in the opinion of the Investigator, they are not producing sedation or contributing to cognitive impairment. The participant must have been on a stable dose for ≥4 weeks prior to screening and throughout the trial.
• ✕. Antidepressants that may, in the Investigator's opinion, affect the participant's cognition (e.g., tricyclic antidepressants). Mild depression or depressive mood arising in the context of AD are not criteria for exclusion. Use of antidepressants is allowed if at stable doses for ≥4 weeks prior to screening and throughout the trial.
• ✕. Antipsychotics used regularly, except for low doses of atypical antipsychotics (e.g., risperidone, aripiprazole, or quetiapine) if used on an as-needed basis or if used at a stable dose for ≥4 weeks prior to screening and throughout the duration of the trial. The definition of "low doses" should be judged by the Investigator, and the Medical Monitor can be consulted if needed.
• ✕. Prior use of levodopa or anti-Parkinsonian medications including dopaminergic agents, amantadine, selegiline, benztropine, and monoamine oxidase (MAO) inhibitors prescribed for the treatment of Parkinsonism or Parkinson's disease.
