Fluorouracilside effects

The following were adverse events considered to be drug related and occurring with a frequency of 1% with fluorouracil cream, 0.5%: application site reaction (94.6%), and eye irritation (5.4%). The signs and symptoms of facial irritation (i.e., application site reaction) are presented below.

Severity of facial irritation at the last treatment visit was slightly below baseline for the vehicle group, mild to moderate for the 1-week active treatment group, and moderate for the 2- and 4-week active treatment groups. Mean severity declined rapidly for each active group after completion of treatment and was below baseline for each group at the Week 2 post-treatment follow-up visit. Thirty-one patients (12% of those treated with fluorouracil cream, 0.5% in the Phase 3 clinical studies) discontinued study treatment early due to facial irritation. Except for three patients, discontinuation of treatment occurred on or after Day 11 of treatment. Eye irritation adverse events, described as mild to moderate in intensity, were characterized as burning, watering, sensitivity, stinging, and itching. These adverse events occurred across all treatment arms in one of the two Phase 3 studies.

A total of five patients, three in the active treatment groups and two in the vehicle group, experienced at least one serious adverse event. Three patients died as a result of adverse event(s) considered unrelated to study drug (stomach cancer, myocardial infarction, and cardiac failure). Post-treatment clinical laboratory tests other than pregnancy tests were not performed during the Phase 3 clinical studies. Clinical laboratory tests were performed during conduct of a Phase 2 study of 104 patients and 21 patients in a Phase 1 study. No abnormal serum chemistry, hematology, or urinalysis results in these studies were considered clinically significant.
