Genprex Inc. (NASDAQ: GNPX)

Genprex Inc. (NASDAQ: GNPX) is a clinical-stage gene therapy company focused on developing life-changing therapies for patients living with cancer and diabetes. The company’s technologies are designed to administer disease-fighting genes to provide new therapies for large patient populations who currently have limited treatment options.

Genprex works with world-class institutions and collaborators to develop drug candidates to further its pipeline of gene therapies in order to provide novel treatment approaches. The company was founded in 2009 and is headquartered in Austin, Texas.

Oncology Pipeline

Genprex’s oncology pipeline aims to reprogram the course of cancer. The company is evaluating its proprietary, non-viral ONCOPREX® Nanoparticle Delivery System, believed to be the first systemic gene therapy delivery platform used for cancer in humans, in multiple clinical programs.

ONCOPREX uses plasmids containing tumor suppressor genes encapsulated within lipid nanoparticles. The resultant product is administered intravenously to the patient to re-express the deleted tumor suppressor genes, which are deleted early in the development of cancer.

REQORSA® Immunogene Therapy

The company’s lead product candidate, REQORSA® Immunogene Therapy (quaratusugene ozeplasmid), is being evaluated in two clinical trials as a treatment for non-small cell lung cancer (NSCLC), and a third clinical trial for small cell lung cancer (SCLC) will open for enrollment in 2023. Notably, both of its NSCLC clinical programs received a Fast Track Designation from the U.S. Food and Drug Administration.

REQORSA consists of the TUSC2 gene (a tumor suppressor gene) expressing plasmid encapsulated in non-viral nanoparticles made from lipid molecules with a positive electrical charge. REQORSA is injected intravenously and can specifically target cancer cells, which generally have a negative electrical charge.

Once REQORSA 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. REQORSA 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. REQORSA has also been shown to be complementary with targeted drugs and immunotherapies.

Genprex’s R&D pipeline for REQORSA in NCSLC includes the Acclaim-1 phase I/II trial in combination with Tagrisso (osimertinib), the Acclaim-2 phase I/II trial in combination with Keytruda (pembrolizumab), the completed ONC-001 phase I dose escalation trial evaluating REQORSA as a monotherapy and the completed ONC-002 phase I trial in combination with Tarceva (erlotinib). In SCLC, Genprex is advancing the Acclaim-3 phase I/II trial in combination with Tecentriq (atezolizumab).

Diabetes Pipeline

Genprex’s diabetes gene therapy approach is comprised of a novel infusion process that uses an adeno-associated virus (AAV) vector to deliver Pdx1 and MafA genes to the pancreas. The candidates in Genprex’s pipeline have demonstrated potential to stabilize glucose levels and reduce insulin requirements in non-human primate studies.

The company’s R&D pipeline for diabetes includes its preclinical candidates, GPX-002 for Type 1 diabetes and GPX-003 for Type 2 diabetes.

The Market for Cancer and Diabetes

Genprex’s cancer-fighting technologies seek to bridge a critical gap by combining with targeted therapies and immunotherapies to provide treatments to large patient populations who have become resistant to them. Genprex technologies are being developed to overcome genomic limitations which are inherent in targeted therapies and immunotherapies in order to provide new treatment solutions to large cancer populations, such as those with lung cancer.

Each year, more people die of lung cancer than of colon, breast and prostate cancers combined. NSCLC is the most common type of lung cancer, accounting for about 82 percent of all lung cancers, according to the American Cancer Society (ACS). Despite radical advances in drug development and novel therapeutic standards, the five-year survival rate for patients with NSCLC with distant spread is 7%.

Developed resistance to leading drugs such as Tagrisso, Keytruda and Tecentriq is inevitable for most patients, putting the average five-year lung cancer survival rate at just 18.6% and highlighting the importance of REQORSA’s demonstrated potential to block the mechanisms that create drug resistance. In terms of healthcare spending, the global lung cancer market is projected to exceed $48.7 billion by 2026.

The diabetes market represents another serious need in the healthcare industry. Roughly 537 million people around the globe are living with diabetes – a figure that is expected to rise to 783 million by 2045. In the U.S., spending relating to Type 1 diabetes is expected to hit $20.3 billion by 2029, while Type 2 diabetes market sales in the U.S. are expected to climb to $57 billion by that same year.

Despite certain advancements in treatment, quality of life remains highly compromised for many with diabetes. Diabetes gene therapies like those being developed by Genprex could hold the potential to provide long-term effectiveness or change the course of the disease.
