Tivic Health Extends its Worldwide License of TLR5 Agonist Entolimod to Include the Treatment of Neutropenia

Tivic Health Systems, Inc. (NASDAQ:TIVC), a diversified therapeutics company, today announced that, on March 28, 2025, it exercised its licensing option for the exclusive, worldwide rights to advance Entolimod™ for a second indication, Neutropenia. This expansion of commercial rights is part of the license agreement with Statera Biopharma for its late-stage Toll-like Receptor 5 (TLR5) immunotherapy program Entolimod™.

Neutropenia is a condition characterized by lower-than-normal levels of neutrophils, a type of white blood cell essential for combating infections. Causes of neutropenia include chemotherapy and radiation treatments, chronic infection, autoimmune diseases, bone marrow disorders and aging.

According to Data Bridge Market Research, the global Neutropenia market is estimated to exceed $20 billion by 2029.

Under the terms of the company's previously announced agreement with Statera Biopharma, Inc., Tivic secured a worldwide exclusive license for Entolimod™ as a potential treatment for acute radiation syndrome, or ARS.

TLRs are a class of protein that plays a key role in the innate immune system. We believe that Entolimod's mechanism of action provides unique, highly sought-after attributes in the treatment of a number of indications besides ARS and Neutropenia. Tivic also has the option to license three additional indications: Lymphocyte exhaustion, Immunosenescence, and chronic radiation syndrome.

"As Tivic prepares for commercial-grade manufacturing of Entolimod, we see the opportunity to leverage that investment across more than one indication," explained Jennifer Ernst, CEO of Tivic Health. "Entolimod and Entolasta have been the subject of more than 40 animal and human trials and $140 million of prior investment. Based on the prior development, we believe that this important immunotherapy drug is ready to advance through the final steps toward a biologics license application filing and potential FDA approval."

Terms of the License Agreement

As previously announced, Tivic Health entered into a license agreement with Statera Biopharma, Inc. to acquire the exclusive worldwide license for the TLR5 agonist program Entolimod™ for ARS as well as the option to acquire the exclusive worldwide license for certain additional indications.

Future payments under the agreement will be milestone-driven, ensuring alignment with the clinical and commercial success of the TLR5 program for the licensed indications. This structure allows Tivic to strategically manage investment while maximizing potential returns as the assets progress toward FDA approval and commercialization.
