E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine whether minocycline is superior to placebo in slowing the disease course of early AD, over a 2-year period, measured by reduced rate of decline in:
(i) Cognition.
(ii) Function.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of MADE are:
(i) To compare the safety and tolerability of minocycline at doses of 400mg/day and 200mg/day
(ii) To determine whether 400mg/day offer superior neuroprotection to 200mg/day.
(iii) To investigate associated risks of side-effects and serious adverse events.
(iv) To estimate the magnitude of any statistically significant positive treatment effects on cognitive and functional decline and thereby inform the design and powering of a future phase III trial of definitive clinical effectiveness within the NHS.
