E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objectives of the study are to evaluate the safety and tolerability of ORM-12741, and the efficacy of ORM-12741 on cognitive symptoms in patients with Alzheimer’s disease (AD) receiving acetylcholinesterase (AChE) inhibitor therapy. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to evaluate the efficacy of ORM-12741 on behavioural symptoms, and plasma trough concentrations of ORM-12741 in patients with AD receiving AChE inhibitor therapy, and to evaluate the effects of ORM-12741 on plasma trough concentrations of the AChE inhibitors. |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
An optional, exploratory pharmacogenetic sub-study is part of the main protocol. In the context of the study, the objective is to assess possible genetic factors that influence the absorption, distribution, metabolism, excretion, efficacy, and safety of ORM-12741 or its metabolites or AChE inhibitor treatments. |
|
E.3 | Principal inclusion criteria |
Male or female patients with diagnosis of probable AD, written informed consent (IC) obtained from the subject and/or his/her caregiver. The subject must have a history of progressive cognitive deterioration, brain imaging consistent with AD, at least a mild level of behavioural symptoms present with a neuropsychiatric inventory (NPI) score > 15, mini-mental state examination (MMSE) score 12-21 at screening visit and be treated with donepezil, rivastigmine or galantamine for at least 3 months. The subject must be 55-90 years of age and fulfil all of the inclusion criteria and none of the exclusion criteria. |

2. Modified Hachinski Ischemia Score > 4.
4. Use of antipsychotics within 2 months prior to screening (even for sleep).
5. Use of benzodiazepines, other than short acting sleep medication, for night at a maximum of 3 nights/week, within 2 months prior to screening.

9. Myocardial infarction within the past 2 years.
10. Current or history of malignancy within the past 5 year.
11. Suicidal ideation in the 6 months before screening or current suicide risk based on the Columbia-Suicide Severity Rating Scale (C-SSRS) (items 4 and 5 exclusionary) or current risk of suicide based on the investigator’s judgement.
12. Subjects with known or suspected history of alcoholism or drug abuse (within the past 5 years).
13. Any other clinically significant cardiovascular, pulmonary, gastrointestinal, hepatic, renal, neurological or psychiatric disorder or any other major concurrent illness that in the opinion of the investigator would interfere with the interpretation of the study results or constitute a health risk for the patient if he/she takes part in the study.
14. Specific findings in MRI that might in the opinion of the investigator affect cognitive function such as cortical infarct, micro-haemorrhage, or silent lacuna (≤ 1 cm) in a region known to affect cognition such as the hippocampus of either hemisphere, the head of the left caudate, or the dorsomedial region of the left thalamus. With the exception of neuroanatomical areas defined, a maximum of one “clinically silent” lacunar infarct is permitted provided the maximal diameter in any dimension is ≤ 1 cm detected on both T1 and T2 weighted MRI images or observed on CT scan images. Multiple white matter lesions consistent with leukoaraiosis are not exclusionary in an otherwise eligible subject.
15. Supine HR > 100 bpm after a 5-minute rest at screening visit.
16. Supine systolic BP (SPB) > 160 or diastolic BP (DPB) > 100 mmHg after a 5-minute rest at screening visit.
17. Symptomatic orthostatic hypotension at screening visit.
18. QTc-Fridericia (QTcF) repeatedly > 450 ms in males or > 470 ms in females at screening visit.
19. Abnormal thyroid-stimulating hormone (TSH), vitamin B12 or folate serum levels at screening (which can not be corrected with substitute therapy).
20. Any other abnormal value in laboratory tests, vital signs or ECG which may in the opinion of the investigator interfere with the interpretation of the study results (e.g. affect cognition) or cause a health risk for the patient if he/she takes part in the study.
21. Female patients of childbearing potential (i.e. menstruating or less than 2 years postmenopausal).
22. Patients with pre-planned elective surgery.
23. Known hypersensitivity to the active substance or to any of the excipients of the study drugs.
24. Blood donation or loss of significant amount of blood within 60 days prior to the screening.
25. Participation in a drug study within 60 days prior to the screening.
26. Previous AD immunotherapy treatment.
27. Patient cannot complete the Cognitive Drug Research Ltd. (CDR) cognitive test battery despite having undergone 2 training sessions.
28. Subjects who reside in a skilled nursing facility.
29. The subject is not able to swallow test capsule at screening.
30. Any other condition that in the opinion of the investigator would interfere with the interpretation of the study results or constitute a health risk for the patient if he/she takes part in the study.

E.5 End points |
E.5.1 | Primary end point(s) |
Efficacy variables:
The following cognitive tests will be assessed: the Cognitive Drug Research Ltd. (CDR) cognitive test battery, the Controlled Oral Word Association Test (COWAT) and the Category Fluency Test (CFT).
Safety variables:
Safety will be assessed by adverse events (AEs), vital signs, 12-lead electrocardiogram (ECG), physical examination and laboratory safety assessments. Suicidality will be assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The CDR cognitive test will be assessed at screening and baseline. At week 1, 2, 4, 8 and 12 - 1 hour after investigational medicinal product (IMP) administration.
COWAT and CFT will be assessed at baseline and at week 1, 2, 4, 8 and 12 visits. |
|
E.5.2 | Secondary end point(s) |
Efficacy:
The following behavioural and psychological symptom tests will be assessed: the NPI and the Cornell Scale for Depression in Dementia (CSDD). In addition, the Cognitive Failures Questionnaire (CFQ) and the overall change in subject’s clinical condition by Clinical Global Impression of Change (CGI-C) will be assessed.
Pharmacokinetic (PK) variables:
Plasma concentrations of ORM-12741, ORM-13720, ORM-13859, ORM-13861, donepezile, galantamine and rivastigmine will be tabulated.
Pharmacogenetic (PG) variables:
All subjects participating in this study will provide a blood sample for extraction of DNA to determine the carrier status for the genes (markers) that have been associated with behavioural and psychological symptoms in AD, or affect the target receptor, and may predict the subject’s response to the study treatment. An additional blood sample for DNA extraction will be taken from those subjects who agree to take part in the optional study-related exploratory PG study.
Sample collection for exploratory studies:
Blood samples will be collected for metabolomics studies to allow possible exploratory studies related to the pharmacokinetics, pharmacodynamics, or safety of ORM-12741, its metabolites or AChE inhibitor treatments.
