Brief 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.
