Study of LM11A-31-BHS in Mild-moderate AD Patients
A 6-months Prospective, Multi-center, Double-blind, Placebo-controlled, Randomized, Adaptive-trial-design Study to Evaluate Safety, Tolerability and Exploratory Endpoints of Either Placebo or Two Different Oral Doses of LM11A-31-BHS in Patients With Mild to Moderate Probable Alzheimer's Disease

Detailed Description
The goal of this AD Pilot is to conduct a prospective, double-blind, multicenter, phase IIa exploratory safety, feasibility and proof-of-concept trial in mild to moderate Alzheimer's disease patients with the orally bioavailable p75 neurotrophin receptor ligand LM11A-31-BHS dosed twice daily for 26 weeks. Successful completion of this trial will provide the safety, endpoint and statistical basis for the design and execution of a phase 2b/3 efficacy trial. It will also bring to the AD field a much-needed new set of target mechanisms and will help pioneer the strategy of the concomitant targeting of multiple fundamental AD-related pathological processes.
During the 26 weeks study period the eligible patients will be invited to 5 visits.
Safety monitoring will include the full extent of phase 2 clinical, electrophysiological and laboratory testing.

- Age 50-85 years (50-80 in Czech Republic)
- MRI or CT assessment within six months before baseline, corroborating the clinical diagnosis of AD and excluding other potential causes of dementia, especially cerebrovascular lesions (see exclusion criteria, number 3)
- CSF AD specific biomarker profile; positive, defined as CSF Aβ42 < 550 ng l-1 or an Aβ 40/42 ratio < 0.89
- Mild to moderate stage of Alzheimer's disease according to MMSE ≥ 18 and ≤ 26
- Absence of major depressive disease according to GDS of < 5
- Modified Hachinski Ischemic Scale ≤ 4
- Formal education for eight or more years
- Previous decline in cognition for more than six months as documented in patient medical records
- A caregiver available and living in the same household or interacting with the patient a sufficient time each week (in Czech Republic: providing personal care for the patient during at least 10 hours per week ) and available if necessary to assure administration of drug
- Patients living at home or nursing home setting without continuous nursing care
- General health status acceptable for a participation in a 6-month clinical trial
- Ability to swallow capsules
- Stable pharmacological treatment of any other chronic condition for at least one month prior to screening
- Stable treatment with one of the acetylcholinesterase inhibitors donepezil (Aricept ®), galantamine (Razadyne®), or rivastigmine (Exelon) or the partial NMDA receptor antagonist with memantine (Namenda®) at least 3-months before baseline Visit or Combination of both treatments mentioned above
- No regular intake of prohibited medications as noted in Section 11.8 of the protocol
- Signed informed consent by the patient, examined and verified to be mentally capable by an independent physician, prior to the initiation of any study specific procedure. Signed consent of the caregiver (see inclusion criteria 10).
Exclusion Criteria:
- Failure to perform screening or baseline examinations
- Hospitalization or change of chronic concomitant medication one month prior to screening or during screening period
