Phase 1 clinical trials of SZN-1326 and SZN-043 initiated and ongoingPreclinical proof-of-concept data for multiple programs presented and published in Q2 continue to validate Wnt modulation for tissue repair SOUTH SAN FRANCISCO, Calif., Aug. 11, 2022 (GLOBE NEWSWIRE) -- Surrozen, Inc. (“Surrozen” or the “Company”) (Nasdaq: SRZN), a company pioneering targeted therapeutics that selectively activate the Wnt pathway for tissue repair and regeneration, today reported financial results for the second quarter of 2022 and provided a corporate update. “With the initiation of clinical trials for our lead therapeutic candidates, SZN-1326 and SZN-043, Surrozen became a clinical stage company in the second quarter of 2022,” said Craig Parker, President and Chief Executive Officer of Surrozen. “During the quarter we also presented data on these programs at Digestive Disease Week, had an article on SZN-1326 published in Cellular and Molecular Gastroenterology and presented data supporting the potential of SZN-413 for the treatment of diabetic retinopathy at the Association for Research in Vision and Ophthalmology annual meeting. We look forward to continuing to advance our lead programs through the clinic, and our research programs toward the clinic.” Second Quarter 2022 & Recent Highlights Lead Product CandidatesSZN-1326 for Moderate to Severe Ulcerative Colitis SZN-1326, a Fzd5 targeted bi-specific antibody, is the first development candidate designed using Surrozen’s SWAP™ technology and targets the Wnt-signaling pathway in the intestinal epithelium. Surrozen is initially developing SZN-1326 for moderate to severe ulcerative colitis and began dosing healthy volunteers in its three-part Phase 1 clinical trial in May 2022. In preclinical animal models of acute and chronic colitis, SZN-1326 has been shown to activate Wnt signaling in the diseased intestine, stimulate intestinal epithelial regeneration, reduce inflammation and reduce disease activity with no treatment related adverse effects observed in 13-week toxicology evaluations in rats and non-human primates (NHPs). An article was recently published on SZN-1326 in Cellular and Molecular Gastroenterology. SZN-043 for Severe Alcoholic Hepatis SZN-043, a hepatocyte-specific R-spondin mimetic bispecific fusion protein targeting ASGR1, is the first development candidate using Surrozen’s SWEETS™ technology. Surrozen is developing SZN-043 for severe liver diseases, initially focusing on severe alcoholic hepatitis, and began dosing healthy volunteers in its Phase 1 clinical study in June 2022. In multiple preclinical animal models of liver injury and fibrosis, SZN-043 has been shown to selectively activate Wnt signaling in the liver, stimulate transient hepatocyte proliferation, improve liver function and reduce fibrosis with no treatment-related adverse effects observed in 4-week GLP toxicology evaluations in mice and NHPs. The Phase 1 clinical studies were posted to the Australian New Zealand Clinical Trial Registry in March 2022. Click HERE for the SZN-1326 posting and click HERE for the SZN-043 posting. Preclinical data on both programs were recently presented at Digestive Disease Week. SZN-413 for Vascular-associated Retinopathies, Including Diabetic Retinopathy and Diabetic Macular EdemaSZN-413, a Fzd4 bi-specific antibody designed using Surrozen’s SWAP™ technology, has the potential to treat retinal vascular associated diseases including diabetic retinopathy and diabetic macular edema. Surrozen recently presented data supporting the potential of SZN-413 for the treatment of retinal vascular diseases at the Association for Research in Vision and Ophthalmology (ARVO) annual meeting. Fzd4-mediated Wnt signaling is known to play a critical role in retinal vascular integrity and function. Data with Fzd4-specific Surrozen Wnt modulating tool molecules have shown that selectively activating Wnt signaling can rescue a disease phenotype in a norrin knockout model. Recent data generated with SZN-413 in preclinical models of retinopathy demonstrated that SZN-413 stimulated Wnt signaling and was able to induce normal retinal vessel regrowth while suppressing pathological vessel growth. Research Pipeline HighlightsLacrimal GlandTear-producing glands rely on Wnt signaling for maintenance of function. Restoration of gland function through activation of Wnt signaling is a potential therapeutic approach to treat dry eye including severe dry eye associated with Sjogren’s Disease. Preclinical data demonstrated that Surrozen Wnt modulating molecules: Stimulated Wnt signaling in the lacrimal glandIncreased tear production within 2 days in a mouse IL-1a lacrimal gland injury model LungRecent discoveries of Wnt responsive progenitor cells in the lung suggest a potential role for Wnt in diseases such as Idiopathic Pulmonary Fibrosis and COPD. Preclinical data demonstrated that Surrozen Wnt modulating molecules: Stimulated Wnt signaling in the lungExpanded Alveolar AT2 cell organoidsReduced injury and improved fibrosis in an acute bleomycin mouse model About Wnt SignalingWnt signaling plays key roles in the control of development, homeostasis and regeneration of many essential organs and tissues, including liver, intestine, retina, lacrimal gland, lung, cornea, pancreas, skin 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 SurrozenSurrozen is a clinical-stage 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.

Financial Results for the Second Quarter Ended June 30, 2022 Cash Position: Cash, cash equivalents and marketable securities for the second quarter ended June 30, 2022 were $92.7 million, compared to $104.3 million as of March 31, 2022. Research and Development Expenses: Research and development expenses for the second quarter ended June 30, 2022 were $9.6 million, as compared to $10.3 million for the same period in 2021. The decrease was primarily due to the completion of manufacturing drug substance for SZN-1326 and SZN-043 in 2021. Research and development expenses include non-cash stock-based compensation expenses of $0.4 million for the second quarter ended June 30, 2022, as compared to $0.2 million for the same period in 2021. General and Administrative Expenses: General and administrative expenses for the second quarter ended June 30, 2022 were $4.5 million, as compared to $2.4 million for the same period in 2021. The increase was primarily related to employee-related expenses, including stock-based compensation expenses, insurance costs and professional service fees, supporting the growth in our operations and costs associated with being a public company.
