Polmacoxib (7 mg/kg; p.o.; daily for 8 weeks) suppresses intestinal polyp formation in ApcMin/+ mice. Polmacoxib (7-15 mg/kg; p.o.; daily from day 27 post-injection to day 111; athymic nude mice; subcutaneous xenograft mouse model) reduces tumor volume and tumor weight by 58% and 48%, respectively, compared to a 48% and 36% reduction following treatment with Celecoxib. Polmacoxib (7-15 mg/kg; p.o.; began on day 14 and continued for 8 weeks; athymic nu/nu mice; orthotopic xenograft mouse model) inhibits CRC growth in an orthotopic xenograft mouse model, reducing tumor weight by 70% using 7 mg/kg or by 83% using 15 mg/kg, compared to a similar 70% reduction following treatment with 500 mg/kg of Celecoxib. |
