LA JOLLA, Calif.--(BUSINESS WIRE)-- Equillium, Inc. (Nasdaq: EQ), a clinical-stage biotechnology company focused on developing novel therapeutics to treat severe autoimmune and inflammatory disorders with high unmet medical need, today announced that it has acquired Bioniz Therapeutics, Inc., a privately held clinical-stage biotechnology company. Bioniz developed its novel structured-domain peptides, including BNZ-1 and BNZ-2, entirely in-house from its proprietary product discovery platform. The Bioniz lead product candidates are multi-specific inhibitors of key disease-driving, clinically validated cytokine targets aimed at addressing unmet needs across a range of immuno-inflammatory indications.

Through the acquisition, Equillium significantly expands its immunology pipeline with a diversified portfolio of first-in-class immuno-inflammatory drug candidates across a range of development stages, consisting of:

BNZ-1: a first-in-class, tri-specific inhibitor of IL-2, IL-9 and IL-15, three inflammatory cytokines implicated in multiple diseases. BNZ-1 has demonstrated clinical proof-of-concept as a novel cytokine inhibitor through a completed Phase 1/2 study in cutaneous T cell lymphoma (CTCL), a dermato-oncology indication, achieving its primary objective of safety and tolerability where the compound was shown to be well tolerated with a favorable safety profile and showed clinically meaningful improvements in mSWAT scores (modified severity-weighted assessment tool). BNZ-1 is Phase 2 ready in alopecia areata, a dermatological autoimmune disorder, and is Phase 2/3 ready in CTCL with open U.S. INDs for each indication and has orphan designation for CTCL in the U.S. and Europe. BNZ-1 is currently formulated for intravenous administration, with subcutaneous formulation development underway. Equillium plans to initially focus further development of BNZ-1 in patients suffering from alopecia areata, where currently no drugs are approved.

BNZ-2: a first-in-class, selective inhibitor of IL-15 and IL-21. BNZ-2 has undergone substantial translational work supporting its potential use as a treatment for various gastrointestinal diseases and is Phase 1 ready for a study planned to include a proof-of-concept evaluation in patients with celiac disease, an immune disorder related to gluten exposure. The high degree of selectivity for IL-15 and IL-21 inhibition aligns well with the demonstrated key involvement of these two cytokines that work synergistically in driving the pathology in celiac disease and other inflammatory gut and hepatic disorders. BNZ-2 is currently formulated for subcutaneous administration where it is positioned to address an unmet need in patients experiencing symptoms despite attempts to maintain a gluten-free diet.

Discovery Platform: Proprietary and patented technology with origins from the National Institute of Health where seminal discoveries in cytokine biology were made. The flexible, structure-based platform is paired with deep in-house knowledge of cytokine pathways and computational modeling to create a discovery capability generating highly differentiated immunology products. The discovery pipeline includes BNZ-3, an advanced pre-clinical candidate that is a stabilized peptide designed to be orally administered and locally acting in the gut to treat GI inflammation.

This robust pipeline, combined with Equillium’s lead asset, itolizumab, a first-in-class anti-CD6 monoclonal antibody being advanced in a Phase 3 study in acute graft-versus-host disease (aGVHD), substantially expands Equillium’s breadth in immunology. This is consistent with our strategy to identify and secure novel drug candidates that are differentiated and synergistic with our expertise in immuno-inflammatory conditions.

“This acquisition is transformative for Equillium. Expanding our pipeline with multiple first-in-class immunomodulatory drug candidates targeting various cytokines sets the stage for significant future potential growth and value creation, including strategic partnering opportunities,” said Bruce Steel, chief executive officer of Equillium. “The synergy of the Bioniz drug candidate portfolio with our current capabilities and expertise in immunology could not be stronger. Given today’s market conditions, we felt the time was right to be strategically opportunistic and we are pleased to add these exciting assets to our pipeline which we believe, in combination with itolizumab, can drive significant value for shareholders. Today, we are well positioned to bring novel therapies to patients living with severe immuno-inflammatory diseases and look forward to advancing these molecules into later stage development.”

David Pyott, chairman of the board of Bioniz added: “We were most impressed with Equillium’s synergistic mission, deep expertise in immunology and inflammation and strong development capabilities that are uniquely positioned to carry Bioniz’s assets forward. We have every confidence in the Equillium team to drive these programs to success, and to fully realize the potential of our pipeline and novel product discovery platform.”

“Our immune system is incredibly complex, with instances of redundancy or synergy seen across a number of key signaling pathways creating challenges for effective therapeutic intervention,” said Stephen Connelly, Ph.D., chief scientific officer of Equillium. “The ability to selectively modulate more than one of these key pathways in a manner that addresses this complexity has significant advantages. We believe the Bioniz lead assets, acting upstream, can do this without the broad immuno-suppressive or off-target effects such as those experienced with JAK inhibitors as a class.”

Alexandre Kaoukhov, M.D., joins Equillium as senior vice president of clinical development to oversee development of the Bioniz assets. Dr. Kaoukhov, a dermatologist with over twenty years’ experience in the biopharmaceutical industry, brings tremendous medical and development expertise to Equillium. Prior to Bioniz, he was head of global development at Almirall, head of medical dermatology at Allergan, principal medical scientific expert at Novartis, and clinical research physician at Galderma. In addition, Nazli Azimi, Ph.D., founder and CEO of Bioniz, will be retained as an advisor to Equillium while other key research and clinical personnel from Bioniz will transition to Equillium.

We are pleased to announce the promotion of Maple Fung, M.D., to senior vice president of clinical development to oversee itolizumab development. Dr. Fung, a board-certified nephrologist, joined Equillium in early 2020 and has been central to the strategy and clinical leadership of the itolizumab programs. Prior to Equillium, Dr. Fung held senior clinical development roles at Arena Pharmaceuticals, Ionis Pharmaceuticals, Ardea Biosciences, and Amgen.

Following the acquisition, Dolca Thomas, M.D., chief medical officer and executive vice president of research and development at Equillium, will be leaving the company. We would like to thank Dr. Thomas for her contributions to the company.

Transaction Details

With the acquisition of Bioniz, Equillium obtained exclusive worldwide rights to all current and future Bioniz products. The transaction consideration is comprised of an all-stock upfront payment of 5,699,492 unregistered shares of common stock of Equillium issuable to Bioniz stockholders, which represents approximately 19.3% of Equillium’s outstanding capital stock. Approximately 97% of the issued Equillium stock is subject to a standard 6-month lock-up provision and thereafter will be released ratably each month over the following 6 months. Equillium is also obligated to pay Bioniz stockholders up to $57.5 million in potential development milestone payments across three Bioniz clinical candidates (BNZ-1, BNZ-2, and BNZ-3) beginning upon first U.S. marketing approval, and up to $250 million in sales milestone payments based upon BNZ-1 achieving calendar year global net sales of $500, $1,000, $1,500, and $2,000 million. Other than the aforementioned milestones, Equillium does not have any third-party obligations with respect to milestones or royalties related to the Bioniz products or platform. Equillium has sole discretion over the timing and extent of advancing clinical development of the Bioniz products. Bioniz was estimated to have modestly positive net working capital at closing.
