“Modafinil for Attentional and Psychomotor Dysfunction in Advanced Cancer: a Double-Blind, Randomized, Cross-Over Trial”, L. E. Lundorff, B. H. Jønsson, P. Sjøgren2009-07-31 ()⁠:

Cognitive impairment seems to be highly prevalent in patients with advanced cancer. Modafinil, a novel vigilance and wake-promoting agent, may be an alternative treatment. We wanted to investigate this treatment on attentional and psychomotor dysfunction in cancer patients.

28 cancer patients with a tiredness score of 50 mm or more on a scale of 0 to 10 (0=no tiredness, 10=worst possible tiredness) and Karnofsky Performance Status 40–70 were included. All medications were kept stable during the trial despite short acting opioids for breakthrough pain.

On day 1 the patients were randomly assigned to receive 200 mg Modafinil orally or placebo and on day 4 they crossed-over to the alternative treatment. Finger Tapping Test (FTT), Trail Making Test (TMT) and Edmonton Symptom Assessment System (ESAS) were evaluated before tablet intake and again 4, 5 hours after.

FTT for the dominant hand as well as TMT were statistically-significantly improved on modafinil (p-values=0.006 and 0.042, respectively). On ESAS, depression and drowsiness also improved statistically-significantly (p-values=<0.001 and 0.038, respectively).

Modafinil in a single dose regimen was significantly superior to placebo regarding two cognitive tests of psychomotor speed and attention. Furthermore subjective scores of depression and drowsiness were significantly improved by modafinil.
