Transaction to Create Nasdaq-listed Company Focused on Advancing Forte’s Late-Stage Clinical Program for Atopic Dermatitis

$14 Million to be Invested by Alger, BVF Partners LP and OrbiMed Prior to the Closing of the Transaction

SAN DIEGO, CA and TORRANCE, CA, USA I February 19, 2020 ITocagen Inc. (Nasdaq: TOCA), and Forte Biosciences, Inc., a privately held clinical-stage biopharmaceutical company developing a live biotherapeutic for the treatment of inflammatory skin diseases, announced today that they have entered into a definitive agreement under which Tocagen will merge with Forte in an all-stock transaction. The merged company will focus on advancing Forte’s clinical program in inflammatory skin diseases, including atopic dermatitis. Upon stockholder approval, the combined company is expected to operate under the name Forte Biosciences and trade on the Nasdaq Capital Market under the ticker symbol FBRX.

An investor syndicate that includes Alger, BVF Partners LP and OrbiMed have entered into a securities purchase agreement to invest $14 million in the combined company, subject to customary conditions. The financing will help fund the further development of the combined company’s clinical programs, including lead asset FB-401, and is expected to close immediately prior to the completion of the merger. The total cash balance of the combined company following the closing of the merger and financing is expected to be approximately $25 million.

Forte’s lead asset, FB-401, is a potentially first-in-class, live biotherapeutic being developed as a topical therapy for the treatment of inflammatory skin diseases, including atopic dermatitis. In a Phase 1/2a trial in adults and pediatrics, FB-401 demonstrated significant efficacy and a favorable safety and tolerability profile. The full trial results will be submitted for publication in a peer-reviewed journal in the first half of 2020. A randomized Phase 2 trial is planned to commence in mid-2020 in adults and pediatrics with atopic dermatitis, providing an expected data readout in mid-2021.

“We are excited about the opportunities created by this merger, as it positions us to become a global leader in inflammatory skin diseases with the funding needed to advance our pipeline towards regulatory approval and potential commercial launch,” said Paul Wagner, president and chief executive officer of Forte. “Our team and advisors are committed to providing new treatment options, particularly for pediatrics with atopic dermatitis, for which few treatment options exist, and we look forward to delivering on this as we advance through development.”

Marty J. Duvall, chief executive officer of Tocagen, remarked, “Following an extensive review of strategic alternatives, we believe that this merger with Forte is in the best interest of Tocagen’s stockholders and has the potential to deliver immediate and long-term value to the stockholders. The strength and dedication of the Forte leadership team, combined with their highly differentiated technology platform and enthusiastic support from leading clinicians, provides a compelling foundation for future success for all stakeholders, and they have our full support.”

About the Proposed Transaction
The merger is structured as a stock-for-stock transaction whereby all of Forte’s outstanding shares of common stock and securities exercisable for Forte’s common stock will be exchanged for Tocagen common stock and securities exercisable for Tocagen common stock. On a pro forma basis and based upon the number of shares of Tocagen common stock to be issued or issuable in the merger, it is anticipated that Tocagen equityholders immediately prior to the merger will own approximately 25.5% of the combined company and Forte equityholders (inclusive of investors in the financing) immediately prior to the merger will own approximately 74.5% of the combined company on a fully-diluted basis on a treasury stock method basis. The actual allocation will be subject to adjustment based on certain financial metrics, including Tocagen’s net cash balance at the time of closing and the amount that the concurrent financing consummated by Forte before the closing of the merger exceeds or is less than $14,000,000. The transaction has been approved by the board of directors of both companies. The merger is expected to close in the second quarter of 2020, subject to the approval of Tocagen stockholders at a special stockholder meeting, the approval of Forte stockholders, satisfaction of a Tocagen minimum cash condition, the closing of the financing as well as other customary conditions.

Ladenburg Thalmann & Co. Inc. is acting as financial advisor to Tocagen for the transaction and Cooley LLP is serving as legal counsel to Tocagen. Wilson Sonsini Goodrich & Rosati, P.C. is serving as legal counsel to Forte.

Management and Organization
The combined company will be led by Paul Wagner, Ph.D., Forte’s president and chief executive officer, and will be headquartered in Torrance, California. The board of directors is expected to be composed of eight members, with six members designated by Forte, including current Forte board members Lawrence F. Eichenfield, M.D. and Dr. Wagner, and two members designated by Tocagen.
