The present invention relates to crystalline forms of (3R)-3-cyclopentyl-3-[4-(7H-pyrrolo[2,3- d]pyrimidin-4-yl)pyrazol-1-yl]propanenitrile salts of Formula I, wherein HX represents at least one acid component, preferably hydrochloric, phosphoric acid, fumaric acid and L-tartaric acid. The invention also relates to the processes for the preparation thereof as well as said use thereof in phamaceutically acceptable compositions. Use of said crystalline forms of ruxolitinib and manufactured salts in the preparation of (3R)-3-cyclopentyl-3-[4-(7H-pyrrolo[2,3-d]pyrimidin-4- yl)pyrazol-1-yl]propanenitrile in the free form or in the form of any phamaceutically acceptable salt thereof is also part of this invention.
