Our mission is to develop life-changing gene technologies for cancer patients through unique, innovative science.
Genprex is a clinical stage gene therapy company committed to pioneering a new approach to treating cancer. We are developing potentially life-changing gene technologies based upon our novel proprietary technology platform, including our initial product candidate, Oncoprex™ immunogene therapy, or Oncoprex. Our platform technologies are designed to administer cancer fighting genes by encapsulating them into nanoscale hollow spheres called nanovesicles. The nanovesicles are then administered intravenously and are taken up by tumor cells where they express proteins that are missing or found in low quantities.

Our lead product candidate, Oncoprex™, targets non-small cell lung cancer. This initial cancer target represents about 85 percent of all lung cancers and causes more deaths each year than any other type of cancer. Lung cancer is the second most common form of cancer, and the five-year survival rate for late stage lung cancer has not improved substantially in a quarter century. Research indicates that our platform technologies may deliver a number of other cancer fighting genes, alone or in combination with other cancer therapies, to combat additional types of cancer.

The Genprex Approach
We are developing gene therapies for treatment of cancer, including our initial drug candidate Oncoprex immunogene therapy. Our gene therapies are designed to administer cancer fighting genes by encapsulating them into nanoscale hollow spheres called nanovesicles, which are then administered intravenously and taken up by tumor cells where they express proteins that are missing or found in low quantities. Our research indicates that when Oncoprex is combined with targeted therapies (such as Tarceva or Iressa) or immunotherapies (such as Opdivo and Yervoy), Oncoprex is synergistic with those drugs, meaning that the combination is more effective than either drug alone. We believe that by combining Oncoprex with targeted therapies and immunotherapies, we can extend the benefit of these approved lung cancer drugs into the large majority of patients who do not now benefit from them, either because the patients’ tumors do not have the molecular profiles that indicate effectiveness of those drugs, or because the patients have developed resistance to those drugs after receiving them for some period of time.

We hold a portfolio of more than 30 patents covering our technologies and targeted molecular therapies.

We are also conducting pre-clinical research to identify biomarkers that will identify patients most likely to benefit from our gene therapies; and to identify additional cancer drugs that will be synergistic with our gene therapies.

Targeted molecular therapies and immunotherapies offer new options for cancer patients.
As targeted therapies and immunotherapies supplant conventional chemotherapies in lung cancer, many lung cancer patients who do not meet specific genomic profiles are unable to benefit from these new therapies. In fact, a majority of lung cancer patients cannot benefit from targeted therapies or immunotherapies. Genprex seeks to bridge a critical gap by combining its gene therapies with targeted therapies and immunotherapies to provide treatments to large patient populations who would otherwise not be candidates for those important drugs.

In a phase I/II clinical trial, Genprex’s leading drug candidate, Oncoprex, is being combined with the EGFR TKI drug Tarceva® (erlotinib) in Stage IIIb/IV non-small cell lung cancer (NSCLC) patients without an activating EGFR mutation and in patients with an activating EGFR mutation who progressed on erlotinib, whether or not they had prior chemotherapy. Patients without an activating EGFR mutation represent the vast majority of lung cancer patients, however these patients are usually not candidates for EGFR TKI therapies due to the absence of this mutation.

Oncoprex is being developed to overcome this genomic limitation and provide a new treatment solution to this majority of lung cancer patients who do not have the activating EGFR mutation that would allow them to benefit from EGFR TKI therapies such as Tarceva.

In addition, patients who have the EGFR activating mutation and do receive an EGFR TKI inhibitor such as Tarceva usually become resistant to these drugs at some point, and no longer benefit from them. Data indicate that Oncoprex may re-sensititize these patients to EGFR TKI drugs such as Tarceva, allowing the patients to benefit for a longer period time.


Scientific Rationale

The active ingredient in our lead product candidate, Oncoprex, is the TUSC2 gene, a tumor suppressor gene.

Our lead product candidate, Oncoprex, consists of a TUSC2 gene encapsulated in a positively charged nanovesicle made from lipid molecules with a positive electrical charge. Oncoprex is injected intravenously and can specifically target cancer cells, which generally have a negative electrical charge. Once Oncoprex is taken up into a cancer cell, the TUSC2 gene is expressed into a protein that is capable of restoring certain defective functions arising in the cancer cell. Oncoprex has a multimodal mechanism of action whereby it interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for programmed cell death, or apoptosis, in cancer cells, and modulates the immune response against cancer cells. Oncoprex has also been shown to block mechanisms that create drug resistance.

Platform Delivery

The Genprex gene therapy platform consists of anti-cancer genes encapsulated in nanovesicles that are delivered intravenously. The Oncoprex TUSC2 gene is encapsulated in a positively charged nanovesicle that binds to actively replicating (and, therefore, negatively charged) cancer cells and then enters the cancer cell through selective endocytosis

Nanoscale Technology
The particle size is small enough to allow Oncoprex to cross tight barriers in the lung but large enough to avoid accumulation or clearance in the liver, spleen and kidney. The cationic charge of the nanovesicle targets cancer cells, and direct nanovesicle fusion avoids target cell endocytosis. A Phase I clinical trial showed that intravenous Oncoprex therapy was proven to selectively and preferentially target primary and metastatic tumor cells, resulting in clinically significant anticancer activity. The nanovesicles are non-immunogenic, allowing repetitive therapeutic dosing and providing extended half-life in the circulation.
