Innovive Pharmaceuticals Announces Preclinical Data from INNO-206 Oncology Program

NEW YORK--(BUSINESS WIRE)--Apr 18, 2007 - INNOVIVE Pharmaceuticals, Inc. (OTCBB:IVPH) announced data from preclinical evaluation of the company's drug candidate INNO-206, a doxorubicin prodrug for treatment of a variety of tumor types. Researchers found that INNO-206, a form of doxorubicin that attaches to circulating albumin and becomes activated once located at the tumor site, is much better tolerated in animal models than doxorubicin alone, a commonly prescribed chemotherapeutic agent. Data was presented today at the American Association for Cancer Research 2007 Annual Meeting in Los Angles, CA.

In a poster presentation titled "Reduced chronic cardiotoxicity and mitochondrial damage of the (6-maleimidocaproyl) hydrazone derivative of doxorubicin (DOXO-EMCH) in a rat model compared to doxorubicin" (Abstract # 5587), researchers concluded:

-- INNO-206 has the potential of inducing less acute and chronic cardiotoxicity in humans compared to doxorubicin

-- INNO-206 low-dose and high-dose groups did not differ from controls with regard to clinical symptomatology and mortality, whereas animal subjects exposed to doxorubicin had a severe clinical and histopathogical cardiomyopathy, marked by enlarged heart with inefficient pumping of blood

-- INNO-206 low-dose and high-dose groups showed a slight increase in heart weights compared to control animals, in contrast to significant increase in heart weight following treatment with doxorubicin

-- INNO-206 low-dose and high-dose groups respectively had low cardiomyopathy scores of one and three on average, in contrast to the doxorubicin group having a high cardiomyopathy score of seven

These data suggest that the proposed Phase II dose of 200 mg/m2 should demonstrate mild to no cardiotoxicity in patients. Innovive intends to initiate a Phase II study in Small Cell Lung Cancer in Q207.

About INNO-206

INNO-206 (formerly DOXO-EMCH) is a doxorubicin prodrug designed to preferentially reach the tumor and reduce adverse events compared to native doxorubicin. A Phase I study of INNO-206 that demonstrated safety and objective clinical responses in a variety of tumor types was completed in 2005 and presented at the March 2006 Krebskongress meeting in Berlin. In this study, doses were administered at up to six times the standard dosing of doxorubicin without an increase in observed side effects over historically seen levels with doxorubicin. Objective clinical responses were seen in patients with sarcoma, breast and lung cancers.
