Innovive Pharmaceuticals Presents Phase I Data on INNO-406 for Treatment of Gleevec-Resistant or Intolerant Chronic Myelogenous Leukemia at ASH

ATLANTA--(BUSINESS WIRE)--Dec 10, 2007 - INNOVIVE Pharmaceuticals, Inc. (OTCBB: IVPH) today presented clinical data from the first part of a two-part Phase I study of its drug candidate INNO-406, a potent, oral, dual Bcr-Abl and Lyn-kinase inhibitor in patients with Chronic Myelogenous Leukemia (CML). In the study, INNO-406 was shown to be well tolerated and demonstrated activity in patients with CML who are intolerant or resistant to imatinib (Gleevec(R)) and multiple second generation tyrosine kinase inhibitors. The data were presented today at an oral presentation at the 49th American Society of Hematology Annual Meeting in Atlanta. -0-

Session Type:  Oral Session on Chronic Myeloid Leukemia: Therapy

               of the CML Advanced Phases


Abstract:      # 469


Title:         "A Phase I Study of INNO-406 in Patients with

               Advanced Philadelphia (Ph+) Chromosome-Positive

               Leukemias Who Are Resistant or Intolerant to

               Imatinib and Second Generation Tyrosine Kinase

               Inhibitors."

The first part of the Phase I, multi-center, open-label study was designed to find the maximum tolerated dose of INNO-406 and involved treating patients in escalating dose cohorts ranging from 30mg once daily (QD) up to 480mg twice daily (BID). Based on results from the first part of the study, Innovive has selected 240mg BID as the optimal dose to continue enrollment in an expansion cohort.

Among the 49 patients enrolled, INNO-406 was generally well tolerated. There were no grade 3/4 pleural effusions, peripheral edemas or pericardial effusions, and dosed patients experienced a low rate of hematologic toxicity and a minimal mean QTc effect. The efficacy data presented were from patients who participated in the dose finding portion of the Phase I study. Of the 20 evaluable CML Chronic Phase patients presented, three complete cytogenetic responses were seen including one in a patient intolerant to both imatinib and dasatinib. Ongoing response data will be obtained for further follow up.

In preclinical studies, INNO-406 has been shown to be 25 to 55 times more potent than imatinib in vitro, and at least 10 times as effective as imatinib in suppressing the growth of Bcr-Abl bearing tumors.

"These data support our belief that INNO-406 is a promising potential therapeutic treatment for patients unable to receive CML therapy after failing one or more tyrosine kinases including Gleevec," stated Steve Kelly, President and CEO of INNOVIVE Pharmaceuticals. "We are pleased with our Phase I data results, and we believe we have established the optimal dose."

About INNO-406

INNO-406 (formerly known as NS-187) is a potent, oral, rationally designed dual Bcr-Abl and Lyn-kinase inhibitor currently in Phase I clinical studies. According to a study published in the journal Blood (Dec. 1, 2005), INNO-406 is 25 to 55 times more potent than imatinib in vitro, and at least 10 times as effective as imatinib mesylate in suppressing the growth of Bcr-Abl bearing tumors. INNO-406 has demonstrated activity in 12 of 13 imatinib-resistant cell lines. In addition to its Bcr-Abl inhibitory properties, INNO-406 inhibits Lyn kinase. Upregulation of Lyn kinase activity is a well-recognized cause of imatinib resistance. Lyn kinase activation has also been documented in a variety of solid tumors, including prostate cancer.
