Brief Summary:
For this project, neflamapimod and placebo will be provided free of charge by the EIP company (www.eippharma.com). Neflamapimod is currently tested in 2 clinical trials in AD, one in Europe (The Netherlands) and one in the USA (clinical trials.gov/VX-745). The company commenced in May 2015 dosing in two phase 2a clinical studies in patients with Early AD: one in the Netherlands that is focused on PET amyloid imaging as the primary biomarker of drug effect, and one in the US (California) that is focused on Cerebrospinal fluid (CSF) evaluation to determine CSF drug concentrations and effects on inflammatory markers and disease biomarkers. Pharmacokinetic evaluation in these patients has demonstrated blood drug concentration levels in the predicted therapeutic range; and importantly, the data from the US study demonstrate that the drug achieves target drug concentrations in CSF, thus confirming the drug robustly enters the brain in humans.
The present project offers us a unique chance to test this promising drug in AD patients. The aim of the study is to focus on PET neuroinflammation imaging as the primary biomarker of this drug effect. The chosen biomarker for imaging neuroinflammation in patients is \[1 8F\]-DPA714.

Detailed Description:
The present project is an intervention proof of concept study to test the efficacy of neflamapimod in a population of AD patients at an early stage.
To track the impact of this drug in patients, the investigators will use an innovative radiotracer, \[18F\]DPA-714, as a promising ligand of microglial activation targeting the translocator protein (TSPO), specific of microglial activation. The use of \[18F\]DPA-714 will allow to monitor the evolution of neuroinflammation in patients as a function of treatment. The main objective will be to compare the level of inflammation using the \[18F\]DPA-714 in neflamapimod and placebo groups after 12 weeks of treatment. Blood and cerebrospinal fluid (CSF) samples and magnetic resonance imaging (MRI) will also be collected to assess inflammation markers and brain structure respectively in these patients.
