Phase II, randomized, double-blind, placebo-controlled study of recombinant human intestinal trefoil factor oral spray for prevention of oral mucositis in patients with colorectal cancer who are receiving fluorouracil-based chemotherapy.

Purpose: This study evaluated the safety and efficacy of recombinant human intestinal trefoil factor (rhITF) administered as topical oral spray for prevention and treatment of chemotherapy-induced oral mucositis (OM).

Patients And Methods: Ninety-nine patients with colorectal cancer who had moderate to severe OM (WHO grade >or= 2) in the first cycle of chemotherapy were randomly assigned to receive either placebo, rhITF 10 mg/mL (ie, low dose), or rhITF 80 mg/mL (ie, high dose) by oral spray (300 microL, eight times each day) for 14 consecutive days in the second chemotherapy cycle. Patients were assessed on days 1, 3, 5, 7, 10, 12, 14, and 21 (+/- 2 days for the last assessment) for safety and for OM incidence and severity.

Intestinal trefoil factor/TFF3 promotes re-epithelialization of corneal wounds.

Disorders of wound healing characterized by impaired or delayed re-epithelialization are a serious medical problem. These conditions affect many tissues, are painful, and are difficult to treat. In this study using cornea as a model, we demonstrate the importance of trefoil factor 3 (TFF3, also known as intestinal trefoil factor) in re-epithelialization of wounds.
