Study summary

The MAPT PLUS study is a two-year extension of follow-up of the patients included in the MAPT preventive study, after completion of the interventions. Subjects in the four groups of the MAPT study will be prospectively followed. MAPT is a multicentre, randomised, placebo-controlled study, using a 4-group design with 3 treatment groups (omega 3 alone, multi-domain intervention alone, omega 3 plus multi-domain intervention, n=420 each) and a placebo group (n=420). The MAPT PLUS study will be an extension of the MAPT study and includes an annual follow-up for two years.

Read the detailed description

The MAPT PLUS study is a follow-up of subjects initially included in an interventional study. The follow-up that we propose in this request for funding does not involve any intervention, but aims to assess the long-term effect of the interventions previously carried out during the three years of the MAPT study.

* Description of the interventions to which subjects are exposed during the first 3 years of follow-up (MAPT study) :

In the MAPT study, subjects are randomized into 4 groups:

  • V0137 CA group: 2 soft capsules of V0137 CA once a day (2 x 400 mg/day);
  • Multi-domain intervention group (nutrition, physical activity, cognitive stimulation, social activities) + placebo, 2 soft capsules once a day ;
  • Multi-domain intervention group (nutrition, physical activity, cognitive stimulation, social activities) + V0137 CA, 2 soft capsules once a day ;
  • Placebo group: 2 soft capsules of placebo once a day. * Description of the multidomain intervention : The multi-domain intervention consists of collective training sessions and a yearly personalized preventive consultation which aims to detect risk factors (sensory disturbances, difficulty in walking, nutritional disturbances, vascular risk factors) and to set up management in collaboration with the general practitioner.

The collective sessions take place in groups of 6 to 8 subjects. In the first month, two sessions a week are scheduled, and in the second month, one session a week. The first two months correspond to the intensive programme. Each session comprises 1 hour of cognitive training, 45 minutes of information on physical activity and 15 minutes of dietary advice. From the third month, sessions are held monthly and aim to consolidate the key messages and to stimulate adherence to the programme. The sessions are shorter (1 hour review of one of the domains of the intensive programme). " Booster " sessions (2 hours) are delivered at 12 and 24 months after the first sessions of the intensive programme. Twenty-minute individual interviews also take place every 6 months with the leader of the training sessions (6 interviews in the course of 3 years).

Inclusion criteria

Subjects who meet the following criteria will be included in the MAPT PLUS study :

  • frail elderly subjects participating in the MAPT study and still followed at 3 years,
  • subjects capable of understanding the protocol, complying with its requirements and attending the follow-up visits proposed as part of the extended phase of the MAPT study,
  • subjects capable of giving their written and complying with the requirements of the study,
  • subjects covered by a health insurance system.

Exclusion criteria

Exclusion Criteria:

Subjects who fulfill at least one of the following criteria will not be included in the MAPT PLUS study :

  • known presence of dementia or Alzheimer's disease (DSM IV criteria) diagnosed during the MAPT follow-up,
  • known presence of severe diseases that are life-threatening in the short term,
  • visual or hearing impairments that are incompatible with performance and/or interpretation of the neuropsychological tests,
  • history and/or presence of any disorder (severe depression or generalized anxiety) which, according to the investigator, is likely to interfere with the results of the study or to expose the subject to a supplementary risk,
  • participation in another clinical study during the period of the present study,
  • subjects who have refused cognitive evaluation during the MAPT follow-up,
  • subjects deprived of their freedom by administrative or judicial decision, or under guardianship,
  • with regard to performance of MRI: presence of a pacemaker or metallic materials, claustrophobia.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
