Equillium to Acquire Metacrine in All-Stock Transaction

Expected to add $33 million in cash at closing to Equillium’s balance sheet and extend operating runway into 2024

Acquisition includes novel drug candidate MET642, an orally delivered Phase 2 ready FXR agonist for ulcerative colitis

Preston Klassen, M.D., MHS, to be appointed to the Board of Directors

LA JOLLA, Calif.--(BUSINESS WIRE)--$EQ #GVHD--Equillium, Inc. (Nasdaq: EQ) and Metacrine Inc. (Nasdaq: MTCR), today announced that the two companies have entered into a definitive merger agreement pursuant to which Equillium will acquire Metacrine in an all-stock transaction. The transaction is anticipated to add $33 million in cash to Equillium’s balance sheet at closing, which is expected to extend the company’s cash runway into 2024. The transaction has been approved by the boards of directors of both companies.

“The acquisition of Metacrine meaningfully strengthens Equillium’s cash position,” said Bruce Steel, chief executive officer at Equillium. “As we continue to execute on our ongoing clinical development programs this cash runway extension is expected to see us through multiple data catalysts and operational milestones, including our interim data readout from the Type B portion of the EQUALISE study in lupus nephritis patients in the coming weeks followed by topline data in 2023; the initiation of a Phase 2 clinical study of EQ101 in alopecia areata; initiation of a Phase 1 SAD/MAD study of EQ102 in normal healthy volunteers and celiac patients; and interim data from both EQ101 and EQ102. While prioritizing our ongoing studies, we will carefully evaluate strategic partnership options to advance the acquired MET642 program, an orally delivered Phase 2 ready FXR agonist program in ulcerative colitis. Dr. Preston Klassen, president and CEO of Metacrine, is ideally suited to help us in this endeavor and we are pleased to announce his appointment to Equillium’s Board of Directors in conjunction with the closing of the transaction.”

“I’m honored to be joining this experienced and talented team,” said Preston Klassen, M.D., MHS, president and chief executive officer of Metacrine. “I look forward to working with the Equillium team to advance their exciting pipeline of clinical programs and explore strategic opportunities for MET642. I strongly believe that Metacrine shareholders will benefit from long-term value created by the combination of our companies.”

Through the acquisition, Equillium adds Metacrine’s farnesoid X receptor (FXR) platform, including lead molecule MET642, an orally delivered FXR agonist that is a potential first-in-class, non-immunosuppressive treatment for inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn’s disease. MET642 is expected to address multiple aspects of IBD pathogenesis including maintenance of epithelial barrier function and reduction of bacterial translocation. Equillium will be seeking a strategic partner with which to advance this program.

Transaction Details

The transaction consideration will be comprised entirely of stock, where Equillium will issue stock valued at a 25% premium over the net cash delivered at closing, which is estimated to be approximately $26 million. Net cash is total cash, cash equivalents, and short-term investments, adjusted by certain factors including debt, which includes term debt with an outstanding principal of $15 million, and other liabilities, as defined in the merger agreement. The stock value will be based on Equillium’s 10-day volume weighted average closing price calculated ten trading days prior to closing, subject to a share price collar ranging from $2.70 to $4.50. In addition, Equillium has agreed to terms on an amended debt facility with Metacrine’s current lender, K2 HealthVentures LLC, whereby Equillium would assume Metacrine’s existing loan with an outstanding principal balance of $15 million, along with potential access to an additional $10 million of committed debt capital. Concurrent with the transaction closing, Equillium intends to retire its existing debt facility with Oxford Finance LLC and SVB, which currently has an outstanding principal balance of $10 million. After paying off its existing debt facility, Equillium expects to add an estimated $33 million of cash to its balance sheet at closing. Equillium is not planning to retain any current Metacrine employees and expects to assume minimal operating expenses while maintaining sole discretion over the timing and extent of advancing development of the Metacrine programs. The acquisition is anticipated to close late 2022 pending approval from both Equillium and Metacrine shareholders, Metacrine having minimum net cash of $23 million, and other customary closing conditions.

Preston Klassen, M.D., MHS, has served as president and chief executive officer and as a member of the board of directors of Metacrine since June 2020. From March 2017 to June 2020, Dr. Klassen served as executive vice president, head of research and development and chief medical officer of Arena Pharmaceuticals, Inc.

About Itolizumab

Itolizumab is a clinical-stage, first-in-class anti-CD6 monoclonal antibody that selectively targets the CD6-ALCAM pathway. This pathway plays a central role in modulating the activity and trafficking of T cells that drive a number of immuno-inflammatory diseases. Equillium acquired rights to itolizumab through an exclusive partnership with Biocon Limited.

About Multi-Cytokine Platform: EQ101 & EQ102

Our proprietary multi-cytokine platform (MCP) generates rationally designed composite peptides that selectively block key cytokines at the shared receptor level targeting pathogenic cytokine redundancies and synergies while preserving non-pathogenic signaling. This approach provides multi-cytokine inhibition at the receptor level and is expected to avoid the broad immuno-suppression and off-target safety liabilities that may be associated with other therapeutic classes, such as JAK inhibitors. Many immune-mediated diseases are driven by the same combination of dysregulated cytokines, and we believe identifying the key cytokines for these diseases will allow us to target and develop customized treatment strategies for multiple autoimmune and inflammatory diseases.

Current MCP assets include EQ101, a first-in-class, tri-specific inhibitor of IL-2, IL-9 and IL-15, and EQ102, a first-in-class, selective inhibitor of IL-15 and IL-21.

About Metacrine

Metacrine, Inc. is a clinical-stage biopharmaceutical company building a pipeline of differentiated therapies to treat gastrointestinal and liver diseases. Metacrine has developed a proprietary farnesoid X receptor (FXR) platform utilizing a unique chemical scaffold, which has demonstrated an improved therapeutic profile in clinical trials.
