  Purpose

The aim of this study is to measure the availability of the PDE10A enzyme in Huntington disease gene expansion carriers (HDGECs) using the recently developed radioligand [18F]MNI-659. The study will be cross-sectional, examining HDGECs at different stages of the disease (pre-manifest, stage 1 and stage 2), in comparison with Healthy Controls (HCs). The HDGECs included in this study will be recruited from the large database of the REGISTRY study.

Primary Outcome Measures:
  • The primary outcome measure will be the distribution volume (VT) in the striatum (caudate and putamen), globus pallidus, and ventral striatum estimated using kinetic and graphical analysis. Thalamus, cortex and cerebellum will also be examined. [ Time Frame: Visit 3: For HD subjects, this will occur within 90 days from the Screening Visit. For Healthy Controls, this will occur within 28 days of Screening visit. ] [ Designated as safety issue: No ]

Estimated Enrollment: 60
Study Start Date: January 2013
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: November 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PET Imaging with [18F]MNI-659

All subjects (both HDGECs and HCs) will receive single intravenous doses of the radioligands [11C]raclopride (non-investigational medicinal product [NIMP]) and [18F]MNI-659 (investigational medicinal product [IMP]).

The radioligands [11C]raclopride and [18F]MNI-659 will be administered at doses less than 10 micrograms, i.e. within the micro dosing concept, and no pharmacological effects are expected.

The injected radioactivity of [11C]raclopride will be 300 MBq/70 kg of body weight ± 10%.

The injected radioactivity of [18F]MNI-659 will be 185 MBq/70 kg of body weight ± 10%.
