November 4, 2025, (Syracuse, New York) — Zetagen Therapeutics, a privately held clinical-stage biopharmaceutical company pioneering first-of-its-kind targeted therapies for both primary and metastatic breast cancer, announced today that its abstract titled “Increased Survival in Nude Mice Inoculated with MCF7 Breast Cancer (BC) in the Mammary Fat-Pad Achieved via a Single Injection of a Lipid-like Hydrogel Emulsion Containing a New Molecular Entity (NME) and N-ally Noroxymorphone (NaN) Compared to Tamoxifen (TAM) and Abemaciclib (ABE)”, has been accepted and will be presented at the 2025 San Antonio Breast Cancer Symposium (SABCS) on Thursday, December 11, 2025.

Zetagen Therapeutics Secures Composition-of-Matter Patents from USPTO for Novel Breast Cancer Platform

July 28, 2025, (Syracuse, New York) — Zetagen Therapeutics, Inc., a private, clinical stage, biopharmaceutical company focused on developing breakthrough therapies, via intratumorally administration, for primary and metastatic breast cancers, announced today they have successfully secured the foundational Composition-of-Matter patents and claims from the USPTO for their proprietary breast cancer platform.
What we do
For Our
Patients
Zetagen is focused on the 330,000 people in the United States and more globally, annually living with some form of bone metastases. We have created a series of novel therapies which address metastatic cancers at progressive stages. Our therapies are designed to suspend cancer, inhibit pain, and regenerate bone with the potential of increasing survival rates. These novel drugs from Zetagen are adjunctive to other cancer treatments and can be locally administered, to bone or soft tissue organs, when the lesion is first detected via a brief out-patient procedure. Pre-clinical studies and peer-review published data have shown the potential to reduce lesion size by 200% and in some cases completely resolve, reduce pain by 400+%, and improve mortality rates of 250%.

Breakthrough Technology

For Metastatic Therapies

The U.S Food and Drug Administration (FDA) has recognized Zetagen’s discoveries with multiple Breakthrough Designations. Zetagen discovered and patented the first-of-its kind molecular pathway designed to suspend cancer, inhibit pain, and regenerate bone. The small molecule has been approved by the FDA since 1971. Our research scientists have discovered an entirely new pathway for this established molecule which, if proven successful in human clinical trials, could create a new treatment paradigm for patients living with metastatic bone lesions and other osteologic conditions.
