EAST SETAUKET, NY--(Marketwired - Jan 4, 2017) - Lixte Biotechnology Holdings, Inc. (OTCQB: LIXT) announced the publication online of Phase 1 results of its novel anti-cancer compound in Clinical Cancer Research, entitled "Safety, tolerability, and preliminary activity of LB-100, an inhibitor of protein phosphatase 2A, in patients with relapsed solid tumors." (https://doi.org/10.1158/1078-0432.CCR-16-2299)
John S. Kovach, M.D., Founder and President of Lixte said "We are encouraged that ten (46.7%) of twenty-one patients receiving at least 2 cycles of LB-100, a small molecule inhibitor of protein phosphatase (PP2A), achieved stable disease without limiting toxicity for up to 15 cycles of therapy including one patient with pancreatic cancer who had a partial regression. PP2A has long been recognized as a potentially important cancer treatment target but its inhibition was thought to be too toxic for clinical use. This Phase 1 study demonstrates the safety and tolerability of PP2A inhibition in patients with refractory solid tumors."
Dr. Kovach continued "In numerous animal models of cancer, inhibition of PP2A by LB-100 enhanced the anti-tumor activity of standard chemotherapy drugs and radiation without significantly enhancing their toxicity by altering cell cycle regulation and the DNA-damage repair response pathways. The mechanism by which LB-100 used alone apparently inhibited the growth of a variety of cancers in patients in the recently completed Phase I trial is not clear but PP2A activity is reduced by mutation directly or indirectly in many cancer types rendering them vulnerable to pharmacologic inhibition of PP2A. The results reported in Clinical Cancer Research support further development of LB-100 alone and in combination with standard cytotoxic regimens for a broad spectrum of tumors."
