Arizona Tribune - Tivic Delivers 200x Scale-up in Manufacturing for Lead Drug Candidate Entolimod(TM) And Achieves Reproducible Yields, Potency and Purity

FREMONT, CA AND SAN ANTONIO, TX / ACCESS Newswire / January 12, 2026 / Tivic Health® Systems, Inc. (Nasdaq:TIVC), a late-stage immunotherapeutics company, today announced it has delivered a 200x scale-up in manufacturing volume for Tivic's lead drug candidate Entolimod™. Entolimod is a TLR5 agonist in development to treat ARS, as well as Neutropenia and other cancer-related conditions. This scale-up was completed by Tivic's wholly owned CDMO, Velocity Bioworks, the acquisition of which has enabled Tivic to quickly advance towards cGMP manufacturing, a requirement for filing a BLA for Entolimod for ARS with the FDA.

As part of the verification and validation process, Tivic successfully demonstrated Entolimod at a 50-liter production volume, equivalent to approximately 1.3 million human doses, with purity and potency meeting all drug release requirements. In addition, yields were consistent with historical batches produced.

"In less than one year, Tivic has accomplished extraordinary acceleration in the potential commercialization of Entolimod -- from initial licensing through completion of cell validation, and now verification of a scale-up batch that represents a 200-fold increase in volume without compromising the drug substance or yields," said Tivic CEO Jennifer Ernst.

"Last month," she added, "Tivic acquired, at a favorable valuation, certain CDMO assets that are now branded as Velocity Bioworks. This acquisition has immediately enhanced our operational and cost efficiencies for manufacturing Entolimod. We anticipate rapidly advancing to commercial-scale production at 200 liters under cGMP conditions, the next step in our path to a BLA filing, and ultimately commercialization."

Ernst concluded, "As we prepare for our meeting with BARDA later this month, we have demonstrated large-scale manufacturing readiness, with the capability to produce millions of doses of Entolimod for ARS. We will also present robust clinical evidence supporting Entolimod's differentiated potential versus existing ARS countermeasures, including its ability to mitigate and prevent both gastrointestinal and hematopoietic injury, reinforcing our strategy to advance Entolimod as a priority therapeutic asset for government partnership or potential acquisition."

About BARDA TechWatch Meetings

BARDA is part of the Administration for Strategic Preparedness and Response and operates within the U.S. Department of Health and Human Services agency to develop, procure, and stockpile medical countermeasures that address chemical, biologic, radiologic, and nuclear public health threats. The TechWatch format enables BARDA and other US agencies to evaluate technology and manufacturing readiness, and potential pathways to funding and purchasing of new technologies. Tivic anticipates exchanging technical information with BARDA, presenting potential development pathways for Entolimod for ARS as a potential mitigant and/or therapeutic in mass-casualty or field deployment situations, and as part of the strategic national stockpile.

About Entolimod
