RestorGenex Announces Presentation of Scientific Data on RES-529 for the Treatment of Glioblastoma at Keystone Symposia on PI 3-Kinase Signaling Pathways

BUFFALO GROVE, Ill., Jan. 23, 2015 (GLOBE NEWSWIRE) -- RestorGenex Corporation (OTCQB:RESX), a specialty biopharmaceutical company focused on developing products for oncology, ophthalmology and dermatology, announced that it presented scientific data on RES-529 for the treatment of glioblastoma multiforme (GBM) at the Keystone Symposia Series on PI 3-Kinase (PI3K) Signaling Pathways. The presentation titled "Validation of RES-529, a novel TORC1/TORC2 allosteric dissociative PI3K inhibitor in glioblastoma multiforme" was presented on January 16, 2015. RES-529 is a proprietary first-in-class PI3K/Akt/mTOR pathway inhibitor that is capable of dissociating both TORC1 and TORC2.

"The data presented help to understand the use of RES-529 and the validity of targeting the TORC1 and TORC2 protein complexes in a dissociative manner for GBM. This, and other work, supports the rationale for RestorGenex's plans to advance RES-529 into clinical trials in GBM," said David Sherris, Ph.D., chief scientific officer of RestorGenex.

The poster presentation discussed in vitro and in vivo data from preclinical studies evaluating RES-529 in GBM, a disease in which elevated expression of the PI3K is commonly seen. In the first study, RES-529 demonstrated an ability to inhibit signal transducers of the PI3K pathway that are controlled by TORC1 and TORC2. This mechanism was shown in a variety of tumor cells, including cells that have lost tumor suppressor PTEN.

In a second study, RES-529 was compared with two catalytic inhibitors of the PI3K pathway currently in the clinic; a combination PI3K/mTOR agent and a combination PI3K/Akt agent. In these experiments, RES-529 showed a 20 to more than 100 fold increase in activity above the other inhibitors. In addition, RES-529 was shown to inhibit tumor cell survival up to two orders of magnitude over that of a rapamycin analog PI3K inhibitor (TORC1 dissociative inhibitor approved by the FDA for select tumor types), in a tumor cell model known to show resistance to TORC1 inhibition.

A third study was presented that demonstrated RES-529 penetrates the blood-brain barrier. This was supported by efficacy data of RES-529 in an orthotopic GBM xenograft model where RES-529 showed an improvement in survival vs. control, similar to radiation treatment. When utilized in combination with radiation, RES-529 showed synergy extending survival above that of either RES-529 or radiation alone.

"GBM is a disease with a very poor prognosis. Less than 10% of newly diagnosed patients survive 5 years. Current standard of care extends overall survival only by approximately 13 to 15 months, and thus there is a clear unmet medical need for novel treatments to treat brain cancer," said Stephen M. Simes, chief executive officer of RestorGenex.
