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.
RESULTS: Treatment of patients at high risk for developing OM with low- or high-dose rhITF significantly reduced the amount of incidence (75% to 81%; low-dose rhITF P<.001; high-dose rhITF P = .002). Frequencies of WHO grade>or= 2 OM in the placebo, low-dose rhITF, and high-dose rhITF groups were 48.5%, 9.1%, and 12.1%, respectively. Assessment of the area under the curve revealed statistically significant reductions in OM severity in the rhITF-treated groups versus placebo. Only a minority of patients (6.1%) reported treatment-emergent adverse events (TEAEs), all of which were mild to moderate in intensity and resolved without sequelae. The incidence of TEAEs was not significantly different among treatment groups.
CONCLUSION: rhITF oral spray formulation was safe and effective when used for the reduction of chemotherapy-associated OM in patients with colorectal cancer. Patients exhibited high compliance in dosing administration. Future clinical study is planned to develop this drug for use in OM management in patients with cancer.
