Surrozen Presents Data Supporting Potential of SZN-043 at The Liver Biology Conference:

Fundamental Mechanisms and Translational Applications

SOUTH SAN FRANCISCO, Calif., June 17, 2021 — Surrozen Inc., a biotechnology company discovering and developing drug candidates to selectively modulate the Wnt pathway, announced today that data from preclinical studies were presented in four oral Abstract Flash Talk presentations during The Liver Biology Conference: Fundamental Mechanisms and Translational Applications. The conference, organized by the Federation of American Societies for Experimental Biology, is being held June 16-17, 2021.

Of the four presentations, one oral presentation analyzed the transcriptome of human livers to evaluate gene expression shifts in alcohol-associated disease. The other oral presentations included data from studies of SZN-043, Surrozen’s hepatocyte-targeted R-spondin mimetic, in normal mice and in various disease models. A replay of the oral presentations and associated copies will be available in the Investors & Media section of Surrozen’s website.

“Severe liver diseases represent a significant area of high unmet need for patients and providers, with severe alcoholic hepatitis alone accounting for 100,000 hospitalizations per year and a mortality rate of 30% within 90 days for patients,” commented Craig Parker, President and Chief Executive Officer of Surrozen. “These data demonstrate why we are encouraged by the mechanism selected to address the condition, as well as affirming that SZN-043 has potential for creating benefit for patients when it advances into clinical studies, which we expect will be in 2022.”

In an oral presentation titled, “Transcriptome Analysis of Human Livers Explants from Alcohol-Associated Liver Diseases Highlights a Loss of Pericentral and Proliferation Gene Expression,” the transcriptome analysis showed liver explants from patients with alcohol-associated liver disease have impairment in pericentral gene expression and hepatocyte proliferation. In addition, Wnt ligands were elevated in these explants. These results suggest that SZN-043, a bispecific fusion protein and hepatocyte-specific R-spondin mimetic, which has been shown to induce pericentral gene expression and hepatocyte proliferation in different mouse models, could be beneficial for the treatment of alcohol-associated liver disease.

In a second oral presentation titled, “SZN-043, a Hepatocyte-Targeted R-spondin Mimetic, Promotes Transient Hepatocyte Proliferation and Zonal Gene Expression Changes in Mice,” results demonstrated SZN-043’s ability to target hepatocytes and transiently promote their proliferation, suggesting its utility as a regenerative therapy for liver diseases.

In a third oral presentation titled, “SZN-043, a Hepatocyte-targeted R-spondin mimetic, Stimulates Hepatocyte Proliferation in an Acute Alcoholic Hepatitis model,” the data showed the potential of SZN-043 to stimulate hepatocyte-specific cell regeneration, to activate the Wnt signaling pathway and to improve hepatic function in aging mice after a prolonged chronic binge ethanol treatment.

In a fourth oral presentation titled, “SZN-043, a Hepatocyte Targeted R-spondin Mimetic, Induces Hepatocyte Proliferation in an Acute Acetaminophen-induced Liver Injury model,” results demonstrated SZN-043 can induce hepatocyte-specific regeneration in an acetaminophen-induced toxicity model, improving liver function and reducing the area of necrosis in the liver.

About Wnt Signaling

Wnt signaling plays key roles in the control of development, homeostasis, and regeneration of many essential organs and tissues, including liver, intestine, lung, kidney, retina, central nervous system, cochlea, bone, and others. Modulation of Wnt signaling pathways has potential for treatment of degenerative diseases and tissue injuries. Surrozen’s platform and proprietary technologies have the potential to overcome the limitations in pursuing the Wnt pathway as a therapeutic strategy.

About Surrozen

Surrozen is a biotechnology company discovering and developing drug candidates to selectively modulate the Wnt pathway. Surrozen is developing tissue-specific antibodies designed to engage the body’s existing biological repair mechanisms with potential application across multiple disease areas, including inflammatory bowel disease, hepatitis, eye diseases, hearing loss, lung and airway diseases, and certain neurological disorders.

Additional Information

In connection with Surrozen’s recently announced business combination with Consonance-HFW Acquisition Corp. (“CHFW”), CHFW has filed with the U.S. Securities and Exchange Commission’s (“SEC”) a Registration Statement on Form S-4 (the “Registration Statement”), which includes a preliminary prospectus with respect to the securities of CHFW to be issued in connection with the business combination to Surrozen stockholders, and as well as a proxy statement with respect to the shareholder meeting of CHFW to vote on the business combination and related matters. CHFW will mail a definitive proxy statement/final prospectus and other relevant documents to its shareholders after the Registration Statement is declared effective by the SEC. This communication is not a substitute for the Registration Statement, the definitive proxy statement/final prospectus or any other document that CHFW will send to its shareholders in connection with the Business Combination. The definitive proxy statement/final prospectus will contain important information about CHFW, Surrozen and their respective business and related risks, the combined company, including pro forma financial information and the proposed business combination and related matters. Investors and security holders of CHFW are advised to read, when available, the proxy statement/prospectus in connection with CHFW’s solicitation of proxies for its extraordinary general meeting of shareholders to be held to approve the business combination (and related matters) because the proxy statement/prospectus will contain important information about the business combination and the parties to the business combination. Investors and security holders of Surrozen are advised to read, when available, the proxy statement/prospectus in connection with the written consent of Surrozen stockholders. The definitive proxy statement/final prospectus will be mailed to shareholders of CHFW as of a record date to be established for voting on the business combination. Shareholders will also be able to obtain copies of the proxy statement/prospectus, without charge, once available, at the SEC’s website at www.sec.gov or by directing a request to: Consonance-HFW Acquisition Corp., 1 Palmer Square, Suite 305, Princeton, NJ.

Participants in the Solicitation

CHFW, Surrozen and their respective directors, executive officers, other members of management, and employees, under SEC rules, may be deemed to be participants in the solicitation of proxies of CHFW’s shareholders in connection with the business combination. Investors and security holders may obtain more detailed information regarding the names and interests in the business combination of CHFW’s directors and officers in CHFW’s filings with the SEC, including the Registration Statement filed with the SEC by CHFW, which includes the preliminary proxy statement of CHFW for the business combination, and such information and names of Surrozen’s directors and executive officers is also in the Registration Statement filed with the SEC by CHFW.
