Modafinil to Improve Fatiguability — MODIFY  

Fatigue Clinical Trial

Official title: Modafinil to Improve Fatiguability (MODIFY): Modafinil vs. Placebo Vanguard RCT

Status Not yet recruiting

Clinical Trial Summary

Cancer-related fatigue (CRF) and cancer-related cognitive impairment (CRCI) are among the most commonly reported disabling symptoms experienced by patients with advanced cancer. However, there are currently limited evidence-based pharmacologic interventions available. The investigators will conduct a Vanguard Randomized Clinical Trial (RCT) to estimate the effect of modafinil in managing CRF and CRCI, and to test the feasibility of carrying out the study.

Clinical Trial Description

Background: Patients with advanced cancer often experience various disabling symptoms. Cancer-related fatigue (CRF) and cancer-related cognitive impairment (CRCI) are among the most common reported symptoms, yet the availability of evidence-based pharmacologic interventions is limited. CRF can be defined as a "distressing, persistent, subjective sense of physical, emotional, and/or cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity and interferes with usual functioning." CRF is experienced by over 75% of patients with advanced cancer. CRCI is defined as a decline in one or more areas of cognitive function, including attention and concentration, executive functioning, information processing speed, language, visuospatial skill, psychomotor ability, and memory. It is estimated that up to 40% of patients experience CRCI prior to any treatment; up to 75% during their treatment; and up to 60% upon completion of therapies. Modafinil is a psychostimulant that has been studied in the context of CRF and daytime sleepiness. Its mechanism of action is not clear, but it is thought to promote wakefulness through dopaminergic neurotransmission which has been hypothesized to play a role in CRF. Study Hypothesis: Modafinil will improve CRF and CRCI Study Objectives: 1. To estimate the effect size of modafinil in managing CRF and CRCI 2. To test the feasibility of carrying out the study (recruitment, etc.) Study Design: Randomized, placebo-controlled, double-blind, single-centre vanguard trial Sample Size & Study Population: Approximately 40 outpatients presenting ≥4/10 on the fatigue score of their screening questionnaire will be recruited. Eligible patients must be 18-75 years old with advanced cancer who have not received cytotoxic chemotherapy for at least one month. Intervention: Subjects will be randomized to receive 200 mg of modafinil or placebo once daily for one week. Study Outcome Measures: Using validated questionnaires and a digital tool, the investigators will assess the patient's fatigue (CRF), cognition (CRCI), and quality of life before and after the intervention. In addition, patients will report their global impression of change. Finally, if patients experience any adverse events (headache, nausea, vomiting, anxiety, etc.), they will report them using a standard questionnaire. Adverse events (AEs) and Serious Adverse Events (SAEs) will be documented. Expected Outcomes: Positive results should provide justification to prolong the study to complete a phase III trial. This study is important because fatigue remains a cause of suffering amongst palliative patients with cancer. Modafinil has the potential to improve patients' fatigue, cognition, and quality of life. ;
