Surrozen Reports First Quarter 2022 Financial Results

On Track to Initiate Phase 1 Clinical Trials in Healthy Volunteers for SZN-1326 and SZN-043 in the Third Quarter of 2022

SOUTH SAN FRANCISCO, Calif., May 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 first quarter of 2022 and provided a corporate update.

“Surrozen remains on track to transition into a clinical-stage organization as our lead product candidates move into clinical investigation in the coming months,” said Craig Parker, President and Chief Executive Officer of Surrozen. “In addition, we recently presented data on SZN-413 for the potential treatment of retinal vascular diseases at The Association for Research in Vision and Ophthalmology and data from our lead product candidates have been accepted for presentation at an upcoming medical conference.”

First Quarter 2022 & Recent Highlights

Lead Product Candidates
SZN-1326 for Moderate to Severe Ulcerative Colitis and SZN-043 for Severe Alcoholic Hepatis

SZN-1326 is the first development candidate designed using Surrozen’s SWAP™ technology and targets the Wnt-signaling pathway in the intestinal epithelium. 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 GLP toxicology evaluations in rats and non-human primates (NHPs). Surrozen is initially developing SZN-1326 for moderate to severe ulcerative colitis.

SZN-043 is the first development candidate designed using Surrozen’s SWEETS™ technology. 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. Surrozen is developing SZN-043 for severe liver diseases, initially focusing on severe alcoholic hepatitis.

Story continues

Surrozen expects to initiate separate Phase 1 clinical trials of SZN-1326 and SZN-043 in healthy volunteers in the third quarter of 2022. 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.

Research Pipeline
SZN-413 for Vascular-associated Retinopathies, Including Diabetic Retinopathy and Diabetic Macular Edema
SZN-413, a Fzd4 bi-specific antibody, has the potential to treat retinal vascular associated diseases including diabetic retinopathy and diabetic macular edema. Surrozen recently presented a poster 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.

Lacrimal Gland
Tear-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. Preclinical data demonstrated that Surrozen Wnt modulating molecules stimulated Wnt signaling in the lacrimal gland andincreased tear production within 2 days in a mouse IL-1a lacrimal gland injury model

Lung
Recent 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 organoids and reduced injury and improved fibrosis in an acute bleomycin mouse model

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.

Financial Results for the Fourth Quarter Ended December 31, 2021

Cash Position: Cash, cash equivalents and marketable securities for the first quarter ended March 31, 2022 were $104.3 million, compared to $123.5 million as of December 31, 2021.

Research and Development Expenses: Research and development expenses for the first quarter ended March 31, 2022 were $9.4 million, as compared to $8.6 million for the same period in 2021. The increase was primarily due to the increase in employee-related costs, including stock-based compensation expenses, as a result of higher headcount in support of progressing our research and development programs towards the clinic. Research and development expenses include non-cash stock-based compensation expenses of $0.3 million for the first quarter ended March 31, 2022, as compared to $0.2 million for the same period in 2021.

General and Administrative Expenses: General and administrative expenses for the first quarter ended March 31, 2022 were $5.1 million, as compared to $4.4 million for the same period in 2021. The increase was primarily related to employee-related expenses, including stock-based compensation expenses, and insurance costs, supporting the growth in our operations and costs associated with being a public company. General and administrative expenses include non-cash stock-based compensation expenses of $0.6 million for the first quarter ended March 31, 2022, as compared to $0.3 million for the same period in 2021.

Other Income: Other income for the first quarter ended March 31, 2022 was $6.5 million, as compared to zero for the same period in 2021. The increase was primarily related to the gain on the change in fair value of warrant liabilities.

Net Loss: Net loss for the first quarter ended March 31, 2022 was $7.9 million, as compared to $13.0 million for the same period in 2021.
