Официальное название

Modafinil for Debilitating Fatigue in Quiescent Inflammatory Bowel Disease: a Multicentre,Randomised, Double-blind, Placebo-controlled, Clinical Trial (MODIFI-IBD Trial)

Обзор

The goal of this clinical trial is to learn if modafinil can treat severe fatigue in adults aged 18 to 75 years with quiescent inflammatory bowel disease (IBD). The main questions it aims to answer are: Does modafinil reduce fatigue more effectively than placebo, as measured by the mean difference in section I of the IBD-F questionnaire at week 8? Is modafinil safe and well tolerated in patients with quiescent IBD and severe fatigue? Researchers will compare modafinil to placebo to see if modafinil improves fatigue outcomes. Participants will: attend one screening visit including assessment of disease activity, blood tests, stool testing, and an ECG; take modafinil or placebo for 8 weeks, starting at 100 mg daily with possible dose increases based on response and tolerability; complete online questionnaires at baseline, week 4, week 8, and week 12 about fatigue, quality of life, sleep, mood, and work productivity; be contacted regularly during the treatment period to discuss effect and side effects of the study medication; complete an online effort-based decision-making task at baseline and week 8.

Подробное описание

Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, is frequently associated with persistent fatigue, even during clinical remission. Fatigue is one of the most burdensome symptoms reported by patients with IBD and is associated with impaired quality of life, reduced daily functioning, and decreased work productivity. Despite its high prevalence and clinical relevance, there are currently no established pharmacological treatment options for fatigue in patients with quiescent IBD.

Modafinil is a centrally acting wakefulness-promoting agent approved for excessive daytime sleepiness in narcolepsy. It has been used for many years and has a well-characterized safety profile. Although its exact mechanism of action is not fully understood, available evidence suggests that modafinil enhances wakefulness and alertness through effects on central dopaminergic signalling. Because fatigue in IBD may involve central mechanisms related to motivation, alertness, and effort processing, modafinil is a biologically plausible candidate treatment for this population. Preliminary clinical observations have suggested that modafinil may reduce fatigue in patients with quiescent IBD, but controlled trial data are not available.

This study is a multicentre, randomized, double-blind, placebo-controlled, multicentre, clinical trial designed to evaluate the efficacy, safety, and tolerability of modafinil in adults with quiescent IBD and severe fatigue. Participants are randomized in a 1:1 ratio to receive modafinil or matching placebo. The treatment period is 8 weeks, followed by a 4-week post-treatment follow-up. To support tolerability and allow individualized treatment, study medication is started at 100 mg once daily and may be increased stepwise during follow-up contacts, based on clinical response and tolerability, up to a maximum daily dose of 300 mg. Participants assigned to placebo follow the same dosing schedule to maintain blinding.

After screening and baseline assessment, most study procedures are conducted remotely to minimize participant burden. Participants complete scheduled study assessments during treatment and follow-up and are contacted regularly by the study team to evaluate treatment response, dose adjustment, and adverse events. In addition to evaluating patient-reported outcomes related to fatigue and broader functioning, the trial includes an exploratory online effort-based decision-making task to assess motivational behaviour. Blood-based biomarker analyses will also be explored to investigate biological factors associated with fatigue and treatment response in IBD.

The placebo-controlled, double-blind design was selected because fatigue is a subjective outcome that is susceptible to placebo effects and expectation bias. This design is intended to allow a more reliable estimate of the specific treatment effect of modafinil. If modafinil is shown to be effective and well tolerated, the results of this trial may support the development of a pharmacological treatment option for an important unmet clinical need in IBD care.

Вмешательства

• Препарат Modafinil
  Modafinil, administered orally as over-encapsulated tablets. Participants start with 100 mg once daily for the first 2 weeks. Depending on clinical response and tolerability, the dose may be increased stepwise during follow-up contacts to a maximum of 300 mg per day. Treatment duration is 8 weeks.
• Препарат Placebo
  Matching placebo administered orally, identical in appearance, dosing frequency, and dose-adjustment schedule to modafinil in order to maintain double blinding. Treatment duration is 8 weeks.
