  • Form 2 was characterizes as a monohydrate, a slightly hygroscopic form that was stable after 1 week at elevated conditions.
  • a metastable nonahydrate (Form 3) was identified and was unstable to drying (losing significant crystallinity) and would convert to Mesylate Form 5 at 40° C./75% RH (and remained as Mesylate Form 3 at 25° C./97% RH).
  • Mesylate Form 4 was a metastable trihydrate that converted to Mesylate Form 1 at 25° C./97% RH and was a mixture of Mesylate Form 1 and Form 4 after 1 week at 40° C./75% RH.
  • a fourth hydrate was then identified and isolated during an initial attempt to prepare the monohydrate. This new hydrate, Mesylate Form 5 was a hygroscopic sesquihydrate that was stable after GVS analysis and remained as Mesylate Form 5 after 1 week at the elevated temperature/humidity conditions.
  • thermodynamic solubility of the anhydrous Mesylate Form 1 and four hydrates was measured in FaSSIF, FeSSIF and FaSSGF media.
  • the anhydrous Form 1 typically displayed the highest solubility (1.90 mg/ml—FaSSIF; 0.34—FeSSIF; 21.0 mg/ml FaSSGF) of the forms except Form 4 (trihydrate) which had slightly higher solubility in FaSSGF (24.0 mg/ml).
