Brief Summary:
This is a Phase 1b, multi-center, randomized, double-blind, placebo-controlled study designed to evaluate the safety, tolerability, and pharmacokinetics of GC021109 in subjects with mild to moderate Alzheimer's Disease (as determined by 2011 National Institute on Aging- Alzheimer's Association [NIA-AA] criteria and Mini Mental State Examination [MMSE]). The Investigator, study site staff, (with exception of a designated pharmacist/pharmacy technician) and all study subjects will be blinded to randomized study medication assignment until database lock. Treatment assignments may be unblinded for select pre-authorized individuals involved in the safety and PK data reviews in order to accurately determine how to proceed with dose escalation.

Arm Intervention/treatment
Experimental: Treatment Cohort 1
Each study participant will be administered with one 1mg dose capsule per day of GC021109 for 28 days.
Drug: GC021109
Placebo Comparator: Placebo Cohort 1
Patients receiving placebo as part of each cohort will be dosed with a comparable capsule to those in the treatment arm of each cohort.
Other: Placebo
Experimental: Treatment Cohort 2
Each study participant will be administered with one dose per day of GC021109 for 28 days. Dose levels will be determined following a review of cohort 1 safety data through day 14
Drug: GC021109
Placebo Comparator: Placebo Cohort 2
Patients receiving placebo as part of each cohort will be dosed with a comparable capsule to those in the treatment arm of each cohort.
Other: Placebo
Experimental: Treatment Cohort 3
Each study participant will be administered with one dose per day of GC021109 for 28 days. Dose levels will be determined following a review of cohort 2 safety data through day 14
Drug: GC021109
Placebo Comparator: Placebo Cohort 3
Patients receiving placebo as part of each cohort will be dosed with a comparable capsule to those in the treatment arm of each cohort.
Other: Placebo



Primary Outcome Measures :
  1. Assessment of the number and severity of treatment-emergent AEs (TEAEs) following single oral doses of GC021109 and placebo from Day 1 through Day 28 [ Time Frame: 28 days ]

Secondary Outcome Measures :
  1. Estimate of the pharmacokinetic (PK) parameters of multiple, escalating dose levels of GC021109: AUC0-t, AUC0-24, AUC0-inf, AUC%extrap, CL/F, Cmax, Tmax, λz, and t1/2. [ Time Frame: 28 days ]
    Change in plasma PK concentrations will be measured pre-dose through Day 28 of the study and PK parameters derived using non-compartmental and/or compartmental methods as appropriate. The following PK parameters of GC021109 will be calculated: AUC0-t, AUC0-24, AUC0-inf, AUC%extrap, CL/F, Cmax, Tmax, λz, and t1/2.

  2. Determine the effect of multiple, escalating dose levels of GC021109 on potential biomarkers of activities. [ Time Frame: 28 days ]
    Plasma and cerebrospinal fluid samples will be collected pre-dose and on Day 28 to analyze biomarkers such as IL-12, amyloid β, and tau.

Ages Eligible for Study:   55 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Male or female subjects aged 55-85 years, inclusive, at the time of informed consent.
  2. Subjects diagnosed with mild to moderate AD as determined by the following:

    1. Diagnosis of probable AD according to the 2011 NIA-AA criteria
    2. MMSE (using serial 7's) score of 12-26 at screening (Mild defined as 20-26 and Moderate defined as 12-19)
    3. Documentation in the clinic notes of mild/moderate AD
  3. If on AD therapy, stable dose for at least 3 months prior to screening.
  4. All male subjects must practice effective contraception during the study. Females of childbearing potential must use a medically accepted form of birth control, unless postmenopausal for > 1 year (as documented by elevated follicle-stimulating hormone [FSH]) or surgically sterile. All females of childbearing potential must have a negative serum pregnancy test (human chorionic gonadotropin beta [hCGβ]) at screening and a negative urine pregnancy test on Day 1 pre-dose.
  5. Body mass index (BMI) between 18 and 35 kg/m2, inclusive, at screening.
  6. Must have an eligible caregiver (who spends a minimum of 10 hours per week with the subject) who will be available for the duration of the study to serve as the subject's designee. Caregiver must be willing to comply with study procedures.
  7. Caregiver must sign a caregiver ICF after the nature and risks of study participation have been fully explained to them.
  8. Patients who are capable, according to the Investigator, or patient's legally authorized representative, must sign a patient ICF after the nature and risks of study participation have been fully explained to them.
  9. Patients who are capable of providing assent but not capable of signing the ICF, according to the Investigator, should provide assent for study participation.

    1. Patients who sign the ICF are not required to provide a separate assent.
    2. Patients who are not capable of providing assent are still allowed to participate provided the patient's legally authorized representative agrees to participation.

    Investigators must document the reasons for any patient that is unable to provide assent and maintain this documentation with the consent/assent documents.

  10. Must be able to comply with all study requirements and restrictions for the duration of the study.
  11. Non-smoker and non-tobacco user for a minimum of 3 months prior to screening and for the duration of the study.

    3. estimated glomerular filtration rate <85ml/min/1.73m2.
  6. Subjects with a QTc of ≥450 msec for males and ≥470 msec for females at screening.
  7. Participation in another clinical trial or treatment with an investigational agent within 30 days or 5 half-lives, whichever is longer, prior to Day 1.
