AUSTIN, Texas, Jan. 5, 2024 /PRNewswire/ -- Genprex, Inc. ("Genprex" or the "Company") (NASDAQ: GNPX), a clinical-stage gene therapy company focused on developing life-changing therapies for patients with cancer and diabetes, today provides a review of its 2023 achievements and a preview of plans for advancing its diabetes and oncology gene therapy programs in 2024.
"We are very proud of what we accomplished in 2023, particularly with the successful completion of the Phase 1 portion of our Acclaim-1 clinical trial in lung cancer," said Rodney Varner, Chairman, President and Chief Executive Officer at Genprex. "In 2023, we also received a third Fast Track Designation for Reqorsa® Immunogene Therapy from the U.S. Food and Drug Administration, this time in combination with Tecentriq® for the treatment of small cell lung cancer, and REQORSA was also granted Orphan Drug Designation for the treatment of small cell lung cancer. We believe these designations underscore and further validate the potential of REQORSA. Our accomplishments in 2023, which also include process improvements in our manufacturing operations and securing new supplies of REQORSA, sets the foundation for a strong 2024."
Oncology Gene Therapy Platform
Genprex's oncology program utilizes its systemic, non-viral Oncoprex® Nanoparticle Delivery System which encapsulates the gene-expressing plasmids using lipid nanoparticles. The resultant product is administered intravenously, where it is taken up by tumor cells that then express tumor suppressor proteins that were deficient in the tumor. The Company's lead product candidate, REQORSA (quaratusugene ozeplasmid), is being evaluated in three clinical trials as a treatment for non-small cell lung cancer ("NSCLC") and small cell lung cancer ("SCLC"), and each of the three lung cancer clinical programs has received a Fast Track Designation from the FDA for the treatment of that patient population.
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 apoptosis (programmed cell death) in cancer cells, and modulates the immune response against cancer cells. In early studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. Genprex's strategy is to develop REQORSA in combination with currently approved therapies and believes that REQORSA's unique attributes position it to provide treatments that improve on these current therapies for patients with NSCLC, SCLC, and possibly other cancers.
Important events of the year included:
Acclaim-1:
The Acclaim-1 study is a Phase 1/2 clinical trial that has three portions - a Phase 1 dose escalation which has been completed, a Phase 2a expansion, and a Phase 2b randomized portion. Acclaim-1 uses a combination of REQORSA and AstraZeneca's Tagrisso® in patients with late-stage NSCLC that has activating epidermal growth factor receptor mutations and progression after treatment with Tagrisso. This novel approach to targeting lung cancer has demonstrated a strong safety profile with early signs of efficacy.
Acclaim-2:
The Acclaim-2 study is a Phase 1/2 clinical trial that has three portions - a Phase 1 dose escalation portion, a Phase 2a expansion portion, and a Phase 2b randomized portion. The Acclaim-2 trial uses a combination of REQORSA and Merck & Co.'s Keytruda® in patients with late-stage NSCLC whose disease has progressed after treatment with Keytruda. Patients are treated at the 0.06 mg/kg dose level in the first cohort of patients and, subject to the Acclaim-2 SRC approval, will be treated at successive dose levels of 0.09 mg/kg and 0.12 mg/kg.
Acclaim-3:
The Acclaim-3 study has two portions - a Phase 1 dose escalation portion and a Phase 2 expansion portion. In November 2022 Genprex filed with the FDA the protocol for the Phase 1/2 Acclaim-3 clinical trial using a combination of REQORSA and Genentech, Inc.'s Tecentriq® as maintenance therapy for patients with extensive stage small cell lung cancer ("ES-SCLC") who develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. Patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced.
Diabetes Gene Therapy Platform
Genprex's diabetes gene therapy approach is comprised of an infusion process that uses an adeno-associated virus ("AAV") vector to deliver Pdx1 and MafA genes directly to the pancreas. In models of Type 1 diabetes, GPX-002 transforms alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body's immune system. In a similar approach, GPX-003 for Type 2 diabetes, where autoimmunity is not at play, is believed to rejuvenate and replenish exhausted beta cells. Genprex has exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education ("University of Pittsburgh") multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. In October 2023, Genprex entered into a one-year extension to the August 2022 sponsored research agreement with the University of Pittsburgh. The extension includes a revised research plan to encompass the Company's most recent technologies to which Genprex acquired exclusive rights from the University of Pittsburgh in July 2023. These include a MafB promoter to drive expression of the Pdx1 and MafA transcription factors that can potentially be used for both Type 1 and Type 2 diabetes. This research is expected to be initially conducted in a Type 1 animal model.
About Genprex, Inc.
Genprex, Inc. is a clinical-stage gene therapy company focused on developing life-changing therapies for patients with cancer and diabetes. Genprex's technologies are designed to administer disease-fighting genes to provide new therapies for large patient populations with cancer and diabetes 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. Genprex's oncology program utilizes its systemic, non-viral Oncoprex® Nanoparticle Delivery System which encapsulates the gene-expressing plasmids using lipid nanoparticles.
