TeraImmune, an Advanced Treg Research Company, headed by Yong Chan Kim, Ph D, brings an approved Treg IND to the Strong Development team from Baudax

Baudax Bio CEO Gerri Henwood to Serve as CEO of Combined Entity

MALVERN, Pa., June 30, 2023 (GLOBE NEWSWIRE) -- Baudax Bio, Inc. (NASDAQ:BXRX) ("Baudax Bio" or the "Company"), a pharmaceutical company focused on innovative products for acute care and related settings, today announced the acquisition of TeraImmune, a privately held a biotechnology company focused on discovery and development of novel Treg-based cell therapies for autoimmune diseases.

"This combination blends the world class scientific expertise of the TeraImmune team with the Baudax team's proven ability to execute clinical development programs, which we believe is a win for the shareholders of both companies," said Ms. Henwood. "This merger adds TeraImmune's TI-168 asset to the Baudax portfolio—a promising next-generation, autologous FVIII TCR-Treg cell therapy candidate to eliminate clotting factor VIII (FVIII) inhibitors in Hemophilia A patients. Hemophilia A is a rare genetic bleeding disorder that is caused by a lack of FVIII, with an Investigational New Drug (IND) application already FDA-cleared. We believe this combination can enable, with a modest initial budget, activating the Phase 1/2a Clinical Trial of TI-168 for Treatment of HA. We believe this is an attractive therapeutic area, with established preclinical proof of concept in TI-168 through successes observed in hemophilic animal models. We believe this platform, with customization to the target condition, has potential for clinical application in management of Myasthenia Gravis, Pemphigus Vulgaris and combination therapies for other conditions such as Organ Transplantation, MS and other auto-immune disorders."

"Concurrently, we intend to continue to progress the development of our existing Neuromuscular Blockade (NMB) portfolio at a prudent pace," continued Ms. Henwood. "With the positive data obtained from our Phase 2 trial of BX1000, we continue to believe that when combined with our reversal agent BX3000 our NMB regimen may provide improved control of neuromuscular paralysis for surgical patients and deliver the first innovation in NMB in decades."

"With IND clearance from the FDA already in hand for TI-168, this transaction permits the continued development of this promising asset," said Yong Chan Kim, PhD, Co-Founder of TeraImmune. "We are looking forward to working with Gerri Henwood and the excellent clinical development team at Baudax to advance this asset to its full potential," said Jihoon (Jay) Park, PhD, Co-Founder of TeraImmune. Daniel Chai, former Board Member of TeraImmune and managing partner of Turret Capital Management said, "We are very excited to see the results that will be driven by the combination of an impressive leadership team and how many lives that can be impacted by the development of this platform technology."

Gerri Henwood, President and Chief Executive Officer of Baudax Bio, will continue as CEO of the combined entity. In conjunction with the transaction, Yong Chan Kim, Ph D, former Chief Executive Officer of TeraImmune, will be appointed to the Board of Directors of Baudax.

About the Transaction

The acquisition of TeraImmune was structured as a stock-for-stock transaction whereby all TeraImmune outstanding equity interests were exchanged for a combination of shares of Baudax common stock, shares of newly designated convertible Series X Non-Voting Convertible Preferred Stock. Subject to shareholder approval of the conversion, each share of Series X Non-Voting Convertible Preferred Stock will automatically convert into 1,000 shares of common stock, subject to certain beneficial ownership limitations set by each holder. On a pro forma basis and based upon the number of shares of Baudax common stock and preferred stock issued in the acquisition, Baudax equity holders immediately prior to the acquisition will own approximately 18% of the combined Company (on an as-converted, fully-diluted basis and excluding certain out-of-the-money warrants held by Baudax' equity holders) immediately after these transactions. The acquisition was unanimously approved by the Board of Directors of Baudax and the Board of Directors of TeraImmune. The closing of the transaction was not subject to the approval of Baudax shareholders.

Nobel Capital provided a fairness opinion to the Baudax Board of Directors.

About Baudax Bio

Baudax Bio is a pharmaceutical company focused on innovative products for acute care and related settings. The Company has a pipeline of innovative pharmaceutical assets including two clinical-stage, novel neuromuscular blocking (NMBs) agents, one that recently completed a Phase II clinical trial and an additional unique NMB undergoing a dose escalation Phase I clinical trial, as well as a proprietary chemical reversal agent specific to these NMBs, which is currently undergoing nonclinical and manufacturing studies to prepare for an expected IND filing in the summer of 2023.

Following the acquisition, the combined company will also advance the development of TeraImmune's innovative immune-cell therapies, leveraging a dual Treg manufacturing platform consisting of both natural regulatory T cells (Tregs) isolated from patients (TREGable™) and induced Tregs converted from a patient's T-effector (Teff) cells (TREGing™). This Treg platform technology is designed for conditions that suppress unwanted immune reactions and includes the allogenic, or off-the-shelf, Tregs obtained from Umbilical Cord Blood for the treatment of skin diseases such as Atopic Dermatitis. The combined company will further the development of Treg therapy specific to HA (pipeline candidate TI-168). TI-168 is a next-generation, FVIII specific Treg therapy designed to reliably and effectively address Hemophilia A patients with FVIII inhibitor. By combining the patented Treg culture method (TREGable^TM) and TeraImmune designed FVIII-specific TCR, the Company has successfully demonstrated the therapeutic concept of FVIII TCR-Treg therapy in controlling of FVIII ADA in a hemophilic animal model. The lead program TI-168 has shown encouraging pre-clinical data and the FDA has cleared an IND to commence a Phase 1/2a clinical trial for the treatment of hemophilia A with inhibition.
