Efficacy and safety of modafinil versus dexamethasone in cancer-related fatigue: a prospective randomized controlled study

Uttiya Deb et al. Future Oncol. 2021 May.

Abstract

The aim of this study was to compare the efficacy and safety of modafinil and dexamethasone in the management of cancer-related fatigue and their effects on quality of life (QoL). A prospective randomized controlled study was conducted, enrolling 80 cancer patients experiencing moderate or severe fatigue following at least three cycles of chemotherapy or a course of palliative/curative radiotherapy. Patients received either oral modafinil 100 mg or dexamethasone 4 mg daily for 14 days. Levels of fatigue, QoL and symptom severity were compared after 14-21 days. Both drugs were efficacious and safe in the management of fatigue and QoL. However, modafinil performed marginally better. Although modafinil demonstrated marginal superiority, both modafinil and dexamethasone can improve fatigue and QoL in cancer patients.

Plain language summary

Lay abstract Cancer-related fatigue is a common and nagging problem that needs best evidence-based management. Modafinil, a brain stimulant, and dexamethasone, a corticosteroid, have been shown in separate studies to provide benefit, but there are little data regarding which one is superior. The present study compared modafinil with dexamethasone in a randomized controlled trial. Modafinil was found to be marginally superior in treating cancer-related fatigue and several domains of quality of life, though dexamethasone also demonstrated significant improvement of fatigue. This study provides a valuable guide for future larger studies for implementation of the findings in the form of better patient care.
