- Subjects currently taking any calcium channel blocker or Beta-blocker
- Subjects who in the opinion of the investigator, have a medical condition that would preclude them from participating in the study (e.g.hemodynamically significant coronary artery disease., chronic heart failure, syncope within the past year, significant valvular heart disease i.e. severe aortic and mitral stenosis.. symptomatic orthostatic hypotension within the last year, subjects requiring more than one agent to control BP.), or subjects who in the opinion of the investigator are unlikely to complete per protocol due to care issues etc:
- Current Axis I diagnosis of schizophrenia, bipolar disorder, major depression. Subjects who are currently or who have within the past year met criteria for drug or alcohol abuse or dependence.
- Pregnant women or women who may possibly become pregnant.
- Subjects with a history of hypersensitivity to nilvadipine (Nivadil).

- Subjects who have taken an investigational or other unapproved drug during the 30 days or five half-lives, whichever is longer, prior to baseline.

About this study
Official title: A European Multicentre Double-blind Placebo-controlled Phase III Trial of Nilvadipine in Mild to Moderate Alzheimer's Disease
Alzheimer's disease (AD) is an ever-increasing public health concern among the aging population and is the most common form of dementia affecting more than 15 million individuals worldwide and around 5 million Europeans. The direct and indirect costs of AD and other dementias amount to more than €440,000 million each year (www.alz.org, 2010).
Even modest therapeutic advances that delay disease onset and progression could significantly reduce the global burden of the disease and the level of care required by patients. While there are symptomatic-based drug therapies available for AD, these medications do not prevent the disease process itself. There is therefore an imperative to develop new treatments for AD that have disease modifying effects. This double-blind placebo controlled study will test the efficacy and safety of nilvadipine in 500 subjects with mild to moderate AD over a treatment period of 18 months. There is a strong scientific rationale for this study: Nilvadipine, a licensed calcium channel enhances Aß clearance from brain and restores cortical perfusion in mouse models of AD. Nilvadipine is safe and well tolerated in AD patients and clinical studies with this medication have shown stabilization of cognitive decline and reduced incidence of AD, pointing to both symptomatic and disease modifying benefits. Male and female patients with mild to moderate AD aged between 50 and 90 with a range of medical morbidities and frailty will be included in the study. If this trial is successful, nilvadipine would represent an advance in the treatment of AD patients and would have a major impact on the health and social care costs incurred in Europe by this neurodegenerative disorder. Furthermore, the creation of the NILVAD network will support future clinical trials and research innovation in AD across Europe.

What is being measured
The primary outcome is the main question the study is designed to answer.
Alzheimer's Disease Assessment Scale (ADAS) Cog
The Alzheimer's Disease Assessment Scale (Cognitive) (Mohs et al. 1983) ADAS-cog 12 is a primary efficacy outcome measure, and includes 12 items of cognitive evaluation, namely immediate word recall, naming objects and fingers, commands, constructional praxis, ideational praxis, orientation, word recognition, remembering test instructions, spoken language ability, word-finding difficulty in spontaneous speech, comprehension \& delayed recall. A higher ADAS-cog score indicates a poorer cognitive function.
Measured: 18 months
Secondary outcomes (2)
Clinical Dementia Rating Scale Sum of Boxes (CDR-sb)
Clinical Dementia Rating Scale Sum of Boxes (CDR-sb) (Morris et al 1993) is the secondary efficacy outcome measure. This is a semi-structured interview with the caregiver and the patient. The patient's performance in the domains of memory, orientation, judgment, problem solving, community affairs, home and hobbies and personal care are assessed. The CDR-sb is scored from 0-18, with the higher score indicated greater impairment.
Measured: 18 months
Disability Assessment for Dementia (DAD)
Disability Assessment for Dementia (DAD) (Gelinas et al. 1999) is a key secondary efficacy outcome measure and evaluates the basic and instrumental activities in daily activities of elderly people with dementia. This 40-item scale addresses a range of functional domains: eating, meal preparation, telephoning, hygienic, dressing, medication, corresponding, finance, leisure, and housework.
Measured: 18 months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Alzheimer's disease (AD) is an ever-increasing public health concern among the aging population and is the most common form of dementia affecting more than 15 million individuals worldwide and around 5 million Europeans. The direct and indirect costs of AD and other dementias amount to more than €440,000 million each year (www.alz.org, 2010).
Even modest therapeutic advances that delay disease onset and progression could significantly reduce the global burden of the disease and the level of care required by patients. While there are symptomatic-based drug therapies available for AD, these medications do not prevent the disease process itself. There is therefore an imperative to develop new treatments for AD that have disease modifying effects. This double-blind placebo controlled study will test the efficacy and safety of nilvadipine in 500 subjects with mild to moderate AD over a treatment period of 18 months. There is a strong scientific rationale for this study: Nilvadipine, a licensed calcium channel enhances Aß clearance from brain and restores cortical perfusion in mouse models of AD.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Alzheimer's Disease Assessment Scale (ADAS) Cog (time frame: 18 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02017340, which also lists 35 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2017.
