Tivic Health Enters GMP Manufacturing Validation Agreement with Scorpius BioManufacturing in Preparation for FDA Submission

Tivic Health® Systems, Inc. (NASDAQ:TIVC), a diversified therapeutics company, announced today it has entered a definitive agreement with Scorpius BioManufacturing to complete the GMP manufacturing validation of the lead candidate from its TLR5 program, Entolimod™, for treatment of Acute Radiation Syndrome, or ARS, in preparation for filing a Biological Licensing application, or BLA, with the U.S. Food & Drug Administration.

Scorpius BioManufacturing, Inc. is an integrated contract development and manufacturing organization (CDMO) and subsidiary of Scorpius Holdings Inc. (OTC:SCPX), which will be the primary U.S. manufacturer for Entolimod™. Scorpius plans to utilize its scientific and technical expertise to validate the commercial manufacturing process for Tivic's lead candidate, Entolimod™.

The GMP Validation Program is valued at approximately $4.1 million and is inclusive of the following activities: cell line verification, legacy process verification, GMP scale-up production, drug product fill and finish, analytical development and qualification, and finally upstream and downstream optimization of the process. All of these activities are designed to ensure Tivic submits to the FDA a complete CMC (chemistry, manufacturing, and control) package for its Entolimod BLA.

Jennifer Ernst, CEO of Tivic, commented, "We believe that Scorpius' specialized focus on manufacturing of biologicals and its experience with Department of Defense programs makes them the perfect partner for completing our GMP manufacturing validation for our FDA BLA filing as well as for commercial production, subject to FDA approval."

Scorpius plans to validate the manufacturing process for Entolimod™ utilizing its facility in San Antonio, Texas. The use of this domestic facility offers a leaner supply chain, ensures the end product is manufactured in the U.S., and provides a streamlined path toward the goal of commercial success. Tivic believes that Entolimod is uniquely positioned for ARS and follow-on applications, as it is potentially the only therapy that can prevent and treat radiation-related damage to both human hematopoietic and gastrointestinal cells.

"We welcome the opportunity to contribute our scientific and technical expertise to delivering the successful manufacture of this important therapy," said Jeff Wolf, CEO of Scorpius. "We look forward to working closely with Tivic and reinforcing Scorpius' reputation as a trusted and innovative biomanufacturing partner."
