The primary outcome is a combination of complete BADL dependency in bathing and dressing and/or institutionalization or death at 2 years after randomization. [ Time Frame: at 30 months after patient's inclusion ]
Institutionalization with date of entry will be assessed by specialist at each follow-up time every 6 months. For patients not coming to the memory consultation, caregiver (formal and/or informal) and/or the general practitioner will be systematically contacted to obtain the information. Death and date of death will be assessed by contacting proxy or general practitioner. In case of lack of information the birth City Hall will be contacted to assess the vital status. For dependency in bathing and dressing, although it could be considered as less objective, we choose a level of total dependency, easy to assess with very low risk of misinterpretation.

  • BADL dependency will be evaluated by the clinician using the BADL scale from Katz [17]. [ Time Frame: at inclusion ]
    Each of the components of the combined primary outcome, as defined above, analyzed separately. As previously demonstrated, bathing and dressing are the first ADL losses, also defined by Katz et al. as the thresholds of disability [17] [18]. A total limitation in bathing and dressing will be considered (each item is coded from 0 - no limitation, to 2 - total limitation).

Comparison of Therapeutic Strategies With Cholinesterase Inhibitors (SOS TRIAL)
Comparison of Therapeutic Strategies With Cholinesterase Inhibitors: Stop or Still (SOS) Trial

Cholinesterase inhibitors (CI) remain the only drugs with a recognized efficacy in mild to moderate Alzheimer's disease (AD) in spite of enormous research efforts. However, these drugs presented as "symptomatic treatment" of AD are considered as having only a weak effect on the course of AD. The reimbursement of these drugs is regularly challenged due to the lack of evidence for the impact of these drugs on milestones stages of AD evolution (survival without severe dementia, restriction in Basic Activities of Daily Living - BADL) and on major consequences in public health (hospitalization and institutionalization). The great majority of previous randomized controlled trials conducted with CI have had a too short duration and the end points were limited to cognition (ADAS Cog scale), IADL (Instrumental Activities of Daily Living) function and Global Impression of Change. New evidences from the DOMINO trial (1) conducted in UK, independently of the pharmaceutical industry, showed that the true effect of CI might be more to avoid or to delay the cognitive or functional decline in AD than to improve patients; the institutionalisation (2) was also delayed. However, this trial was conducted in patients with moderate to severe AD, and the interest of the drugs at the mild to moderate stage remains questionable.

The investigators have shown that a good surrogate marker of survival without severe dementia would be an increase of ADAS Cog scale of more than six points (3). A post hoc reanalysis of the pivotal RCT with two CI showed that in mild to moderate patients, CI was associated with a 15% decrease of patients with a deterioration of ADAS-Cog of more than six points in six months. Thus at the beginning of dementia the real effect of CI might be more of delaying the cognitive and functional decline, than to improve the patients. The main objective of the SOS trial is to demonstrate that the benefit of CI at the early phase of dementia is the same as at the later phase.

Interventional
Phase 4
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
  • Alzheimer Disease
  • Cholinesterase Inhibitors
Drug: cholinesterase inhibitors (CI) (donepezil, galantamine or rivastigmine)

The choice of the treatment will be done by the specialist according to his habits; the specialist will monitor the treatment as usual. All the recruited patients will be treated by CI according to the recommendations of the French HAS and the clinician's habits to choose the type of CI and adjust the dosage. After a 6-month period under CI treatment, patients will be classified according to the evolution of the Mini Mental State Examination (MMSE) as "non-responders" or responders.

Responders patients will continue their treatment according to the habits of the clinician. Non-responder patients will be included in the RCT, with individual randomization in two groups: one group who stops the CI, one group who continues the CI. All randomized patients will then be followed-up for two years with regular assessment of judgment criteria every 6 months.

  • Experimental: Group randomized for continuing treatment

    Group who continues the cholinesterase inhibitors (CI). The treatment is one of the CI (donepezil, galantamine or rivastigmine) with market authorization and commercialized for more than 15 years in France. The choice of the treatment will be done by the specialist according to his habits; the specialist will monitor the treatment as usual.

    All randomised patients will then be followed-up for two years with regular assessment of judgment criteria every 6 months.

    Intervention: Drug: cholinesterase inhibitors (CI) (donepezil, galantamine or rivastigmine)
  • No Intervention: Group randomized for stopping treatment
    Group who stops the CI. No placebo will be given, over 2 years All randomised patients will then be followed-up for two years with regular assessment of judgment criteria every 6 months.
