Insights

Canadian patent allowance modestly strengthens Genprex’s REQORSA lung cancer franchise.

The Notice of Allowance in Canada extends protection for REQORSA Gene Therapy when combined with PD-1 or PD-L1 antibodies in both non-small cell and small cell lung cancer. It complements existing combination patents across multiple major markets.

This intellectual property support aligns with the ongoing Acclaim-3 clinical trial, which evaluates these therapeutic combinations. While no clinical or financial data are provided, the added Canadian coverage may help safeguard future partnering or commercialization discussions if trial results are favorable.

The filing also cites Canadian Cancer Society statistics showing high incidence and mortality for lung and bronchus cancer in 2026, framing a sizable potential patient population. Future clinical readouts and any partnering moves disclosed in later reports will be key to understanding the real-world impact of this IP expansion.

Notice of Allowance regulatory
"the Canadian Intellectual Property Office has issued a Notice of Allowance"
A notice of allowance is an official confirmation from a patent office that a patent application has met all necessary requirements and is approved for granting. It signals that the invention is likely to receive legal protection soon, which can be important for investors considering the value and exclusivity of a new product or technology. Think of it as a green light indicating that the invention is on track to become legally protected.
REQORSA Gene Therapy medical
"for a patent covering the use of Reqorsa® Gene Therapy (quaratusugene ozeplasmid)"
PD-1 medical
"in combination with either PD-1 or PD-L1 antibodies for the treatment"
PD-1 is a protein found on certain immune cells that acts like a brake, signaling the immune system to slow down and avoid damaging healthy tissue. Drugs that block PD-1 release that brake so immune cells can better attack cancer cells; because such therapies can produce large clinical benefits, regulatory approvals, trial outcomes, pricing and market uptake for PD-1 drugs can materially affect a drugmaker’s prospects and investor returns.
PD-L1 antibodies medical
"in combination with either PD-1 or PD-L1 antibodies for the treatment"
PD‑L1 antibodies are drugs that block a protein cancer cells use to hide from the immune system, allowing the body's defenses to recognize and attack tumors. Think of them as removing a disguise so security guards can spot intruders — they matter to investors because clinical effectiveness, safety, regulatory approvals, and patent position determine potential sales, market share, and long‑term value in the cancer therapy market.
non-small cell lung cancer medical
"for the treatment of both non-small cell lung cancer and small cell lung cancer"
A broad category of lung tumors that grow from the cells lining the airways and make up the majority of lung cancer cases; it includes several subtypes that behave and respond to treatment differently, like different models of the same car family. It matters to investors because its large patient population and variety of treatment options — surgery, traditional chemo, targeted drugs and immunotherapies — create major markets where clinical trial results, drug approvals or changing treatment guidelines can quickly affect a company’s revenue and stock value.
forward-looking statements regulatory
"Statements contained in this on regarding matters that are not historical facts are “forward-looking statements”"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Item 8.01 Other Events.
 
On June 22, 2026, Genprex, Inc. (“Genprex” or the “Company”) issued a press release in which it announced that the Canadian Intellectual Property Office has issued a Notice of Allowance to Genprex for a patent covering the use of Reqorsa® Gene Therapy (quaratusugene ozeplasmid) in combination with either PD-1 or PD-L1 antibodies for the treatment of both non-small cell lung cancer and small cell lung cancer. This patent will expand on the previously granted patents for REQORSA in combination with PD-1 and PD-L1 antibodies, which have been granted in the U.S., Japan, Mexico, Russia, Chile, China, Singapore Europe, Korea, Australia and Israel.  The Company believes securing this patent strengthens Genprex’s intellectual property portfolio, providing crucial protection for the therapeutic combinations currently being evaluated in the Acclaim-3 clinical trial.
 
REQORSA is initially being developed in combination with prominent, approved cancer drugs to treat lung cancer. In preclinical studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. The Company believes REQORSA’s unique attributes position it to provide potential treatments that improve on these current therapies for patients with lung cancer and possibly other cancers.  The press release noted that according to the Canadian Cancer Society, lung and bronchus cancer is the most commonly diagnosed cancer in Canada (excluding non-melanoma skin cancers). It is the leading cause of death from cancer for both men and women in Canada. It is estimated that 32,900 people in Canada will be diagnosed with lung and bronchus cancer in 2026, representing 13% of all new cancer cases. It is also estimated that 19,300 people in Canada will die from lung and bronchus cancer in 2026, representing 22% of all cancer deaths.
