Cellceutix's Cancer Drug Shows No Significant Indications of Toxicity

BEVERLY, Mass., July 22, 2009 (GLOBE NEWSWIRE) -- Cellceutix Corporation (OTCBB:CTIX - News), announced today that it has completed acute toxicity studies in mice and rats with its proprietary pharmaceutical compound Kevetrin(TM). In these studies Kevetrin showed no significant indications of toxicity.

"These results are consistent with other animal studies we have conducted," said Dr. Krishna Menon, President and Chief Scientific Officer of Cellceutix. "Coupled with the results previously disclosed of tumor growth delay in animal models of multi-drug resistant lung cancers, we consider this a significant milestone for our shareholders."

In the acute toxicity mouse study, animals were sorted into 4 groups of twenty animals, each comprised of ten male and ten female mice. One group served as the controls and the other three groups were administered a single dose of 150 mg/kg, 200 mg/kg or 300mg/kg of Kevetrin. Animals were observed for 15 days. Data was periodically collected measuring food consumption, body weight and various blood chemistry parameters. At the conclusion of the 15 day trial, post-mortem examinations were made of all the mice. In this study there were no significant indications of toxicity in the mice that had been dosed with Kevetrin.

In the acute toxicity rat study, animals were sorted into 4 groups of ten animals, each comprised of five male and five female rats. One group served as the controls and the others were administered a single dose of 160 mg/kg, 200 mg/kg or 240 mg/kg of Kevetrin. Animals were followed for 15 days. Data was periodically collected measuring food consumption, body weight and blood chemistry parameters. At the conclusion of the 15 day trial, post-mortem examinations were made of all the rats. In this study there were no significant indications of toxicity in the rats that had been dosed with Kevetrin.
