Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 7

  1. Patient is able and willing to provide written informed consent
  2. Age between 18 to 75 years at screening≥1 year diagnosis of IBD, based on a combination of clinical, endoscopic, histologic and radiologic criteria
  3. Chronic fatigue for at least 6 months
  4. Severe fatigue as confirmed with a score of ≥11 on section I of the IBD-F
  5. Clinically quiescent IBD with a Harvey Bradshaw Index (HBI) <5 for CD patients or a Simple Colitis Clinical Activity Index (SCCAI) ≤2 for patients with UC or IBD-unclassified
  6. Fecal calprotectin <150 µg/g
  7. Stable IBD medication (or absence of IBD medication) for ≥3 months before randomization and no change in IBD medication planned for ≥3 months

Exclusion criteria 7

  1. Contraindications for the use of modafinil, such as but not limited to uncontrolled hypertension and cardiac arrhythmia
  2. Patients using medication which interacts clinically significant with modafinil
  3. Patients using pharmacological agents with similar effects to modafinil, like central nervous system (CNS) stimulants or other wakefulness-promoting drugs such as methylphenidate and amphetamines
  4. Participation in another intervention study (excl. registries and post marketing studies)
  5. Pregnant at the moment of the screening visit or planning pregnancy within 2 months after last dose
  6. Planned surgery before or during study period that impacts ability to participate in this study, per investigator judgement
  7. Confirmed diagnosis of other potential causes of fatigue, such as anaemia, specific vitamin deficiencies as well as somatic or psychiatric comorbidities

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The mean difference in section I of the IBD-F questionnaire at week 8

Secondary endpoints 11

  1. Difference in Inflammatory Bowel Disease Questionnaire (IBDQ) comparing baseline with week 4, 8 and 12
  2. Difference in EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) comparing baseline with week 8 and 12
  3. Difference in Pittsburgh Sleep Quality Index (PSQI) comparing baseline with week 8 and week

  6. Difference in the IMTA Productivity Cost Questionnaire (iPCQ) comparing baseline with week 8 and week 12
  7. The incidence of treatment-emergent adverse events, serious adverse events, events of clinical interest and adverse events that lead to discontinuation of modafinil use until 30 days post end of treatment
  8. To evaluate the effect of modafinil on cognitive processes related to motivation, an exploratory endpoint will assess effort sensitivity and reward sensitivity using a validated online effort-based decision-making task
  9. To explore the association between blood based biomarkers and their ability to identify fatigue in IBD
  10. Difference in FACIT-F questionnaire comparing baseline with week 4, 8 and 12
  11. Difference in section I of the IBD-F questionnaire comparing baseline with week 4 and week 12
