The Prexigebersen phase II trials for AML are located at MD Anderson, Weill Cornell Medical College Presbyterian Hospital, Baylor, New Jersey Hematology Oncology Associates, West Virginia University and University of Kansas.
Bio-Path Holdings is focused on antisense drugs which work at a cellular level to interrupt protein production by the diseased cell. The lead drug, Prexigebersen is targeting the Grb-2 protein. Bio Path Holdings' delivery system is a small molecule neutral liposome system. Through the phase 2 of the combination trial for Prexigebersen there has been absolutely no toxicity. The results of testing performed by Bio Path demonstrates an uptake of the drug at a cellular level. The pErk results demonstrate not only a 50+% knockdown of the target protein but shows the pathway was shut down validating the delivery system. The purpose of phase 2 will be to test the effectiveness of the drug. Interim results are positive.
A CML combination drug safety study with Sprycel (Dasatinib) for Prexigebersen has begun at MD Anderson.
Patent protection for manufacturing their neutral lipid delivery system has been granted.
The company was founded on the technology from M.D. Anderson Cancer Center at the University of Texas in Houston. M.D. Anderson is the largest insitutional shareholder. After raising additional funds the company has 2+ million in cash. BIO-PATH'S viability is in question due to a lack of funds.
