New combination drug controls tumor growth and metastasis in mice

Researchers at UC Davis, University of Massachusetts and Harvard Medical School have created a combination drug that controls both tumor growth and metastasis. By combining a COX-2 inhibitor, similar to Celebrex, and an epoxide hydrolase (sEH) inhibitor, the drug controls angiogenesis (blood vessel formation), limiting a tumor's ability to grow and spread. "We've been studying the effects of COX and sEH inhibitors, both by themselves and in combination, for several years," said senior author and UC Davis Distinguished Professor Bruce Hammock. "We were surprised to find that the dual inhibitor was more active than higher doses of each compound, either individually or together. By combining the two molecules into one we got much greater potency against several diseases and completely unique effects in terms of blocking tumor growth and metastasis." Read more here.
