Solid forms of a gamma-secretase modulator

Abstract

The present invention provides novel crystalline solid forms of (R)-7-(3,5-difluorophenoxy)-N-((1R,5S,8s)-3-(6-methoxypyridazin-4-yl)-3-azabicyclo[3.2.1]octan-8-yl)-6,7-dihydro-5H-pyrrolo[1,2-b][1,2,4]triazol-2-amine. Moreover, the invention relates to pharmaceutical compositions comprising said novel solid forms, to processes for making them and to their use as pharmaceutically active compounds.
