  • Clinically relevant abnormal medical history, concurrent medical condition, acute or chronic illness or history of chronic illness sufficient to invalidate the subject's participation in the trial or make it unnecessarily hazardous.
  • Surgery (eg stomach bypass) or medical condition that might affect absorption of study drug taken orally.
  • Presence of abnormal physical findings, ECG, or laboratory values at the pre-trial screening assessment that could interfere with the objectives of the trial or the safety of the subject.
  • Positive tests for hepatitis B & C, HIV
  • Presence or history of drug or alcohol abuse during the last 10 years, or intake of more than 21 units of alcohol weekly.

  • Use of dietary supplements or herbal remedies (such as St John's Wort) known to interfere with the CYP3A4 and/or P-gp metabolic pathways during the 28 days before the first dose of trial medication (see list in Study Procedures Manual)

Additional exclusion criteria for cohort with ophthalmological assessments:

  • No contact lenses wear within 1 month prior to first dose of IMP. Contact lenses wear is not permitted during the study
  • Any ocular disorder for which topical ocular therapy is currently or chronically prescribed, including inflammatory eye disease (dry eye allergic conjunctivitis [seasonal allergic conjunctivitis, vernal keratoconjunctivitis, atopic keratoconjunctivitis], uveitis and glaucoma)
  • Past history of ocular disease requiring ongoing treatment
  • Past ocular surgery including laser or other refractive corneal surgery
  • Evidence of eye irritation, visual difficulties, corneal opacity, ocular surface (corneal or conjunctival damage, with or without ocular symptoms)
  • Evidence of narrow anterior chamber angles causing increased risk of acute glaucoma
  • Evidence of ocular media opacity including lens opacity/vitreous opacities
  • Evidence of retinal or optic nerve pathology
  • Evidence of pronounced colour blindness, as indicated by an Ishihara score of 9/13 or below
