The invention features methods and compositions for treating or preventing lesions of the upper alimentary canal, particularly oral aphthous or mucositis lesions. Trefoil peptides are administered in effective concentrations either alone or in combination with different therapeutic agents.
1 . A method for inhibiting occurrence or expansion of ulcerative oral lesions in a human patient having oral mucositis comprising orally administering to said patient a therapeutic composition comprising human pS2 in an amount effective to inhibit occurrence or expansion of said ulcerative oral lesions.
2 . The method of claim 1 , wherein said oral mucositis is caused by antineoplastic chemotherapy.
3 . The method of claim 1 , wherein said oral mucositis is caused by antineoplastic radiation therapy.
4 . The method of claim 1 , wherein said therapeutic composition is administered to said patient during or within three days prior to a course of antineoplastic chemotherapy.
5 . The method of claim 1 , wherein said therapeutic composition is administered to said patient during or within three days prior to a course of antineoplastic radiation therapy.
6 . The method of claim 1 , wherein said therapeutic composition is formulated as an oral rinse, an oral spray, an ointment, a paste, a cream, a gel, chewing gum, a chewable tablet, a lozenge, or a bioerodable film.
7 . The method of claim 6 , wherein said therapeutic composition is self-administered.
8 . The method of claim 6 , wherein said therapeutic composition is formulated as an oral rinse.
9 . The method of claim 8 , wherein said therapeutic composition is self-administered.
10 . The method of claim 8 , wherein said therapeutic composition is administered in multiple individual daily doses.
11 . The method of claim 1 , wherein said therapeutic composition comprises a mucoadhesive excipient.
12 . The method of claim 1 , further comprising administering to said patient a second therapeutic, wherein said human pS2 and said second therapeutic are administered within 14 days of each other.
13 . The method of claim 12 , wherein said second therapeutic is an anti-inflammatory agent, an antibacterial agent, an anti-fungal agent, an anti-viral agent, or an analgesic.
14 . The method of claim 13 , wherein said antibacterial agent is a tetracycline.
15 . The method of claim 13 , wherein said anti-fungal agent is nystatin.
16 . The method of claim 13 , wherein said anti-viral agent is acyclovir.
17 . The method of claim 13 , wherein said analgesic is lidocaine.
18 . The method of claim 12 , wherein said human pS2 and said second therapeutic are administered in the same formulation.
19 . The method of claim 12 , wherein said human pS2 and said second therapeutic are administered in different formulations.
20 . The method of claim 12 , wherein said human pS2 and said second therapeutic are administered within 24 hours of each other.
