SOUTH SAN FRANCISCO, Calif., Nov. 06, 2024 (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 provided third quarter 2024 financial results and business updates.
"In the third quarter, we made substantial progress on enrolling patients in the SZN-043 Phase 1b trial, received notification that Boehringer planned to further develop SZN-413 to advance the compound and prepare it for clinical testing and nominated a portfolio of novel preclinical ophthalmology candidates," said Craig Parker, President and Chief Executive Officer of Surrozen. "More recently, we also announced a research collaboration with TCGFB to utilize Surrozen's antibody developments capabilities and expertise to discover antibodies targeting TGF-β. We remain focused on transforming the treatment of severe diseases of the liver and eye through leveraging our research capabilities and expertise in antibody engineering technologies."
Research and Development Pipeline Highlights
SZN-043
Surrozen is developing SZN-043 for severe liver disease with an initial focus on severe alcohol-associated hepatitis. The Phase 1b study is enrolling patients and the Company expects proof-of-concept data in the first half of 2025. The study is being conducted at nine sites in five countries.
Surrozen successfully completed dosing and 30-day follow-up for cohort 1 in its Phase 1b trial of SZN-043 in severe alcohol-associated hepatitis (sAH). No drug related serious adverse events (SAEs) were observed in the first cohort of six patients receiving 0.5mg/kg of SZN-043. There were no patient deaths at day 30 of the study, and the company observed a potential clinical benefit based on reductions in bilirubin and MELD score. A majority of patients experienced improvements in AST and ALT levels. Surrozen expects to present data from the Phase 1b study at an upcoming liver disease conference.
"Published data in the severe alcohol-associated hepatitis population indicates an expected mortality rate of approximately 15 to 20% at day 30 and absence of any improvement in markers of liver physiology such as bilirubin", said Craig Parker, President and Chief Executive Officer of Surrozen. "We are encouraged to see that SZN-043 is safe at the first dose level in the study and showing signs of providing a clinical benefit to patients. We're also looking forward to data from additional higher dose cohorts of sAH patients in the study. This preliminary data appears to indicate SZN-043's mechanism of stimulating hepatocyte specific regeneration in the liver through Wnt signaling translates to beneficial changes in liver function and potentially clinical benefit."
Nominated Novel Portfolio of Ophthalmology Preclinical Product Candidates to R&D Pipeline
Surrozen developed multiple novel ophthalmology product candidates targeting Fzd4
leveraging the Company's antibody research capabilities and expertise in antibody engineering technologies. Wnt signaling has been implicated in multiple diseases and tissues in the eye. These product candidates do not fall within the scope of the partnership with BI and are wholly owned by Surrozen.
Product Candidates SZN-8141 and SZN-8143
Data generated in preclinical models of retinopathy demonstrated that SZN-8141 and SZN-8143 stimulated Wnt signaling and induced normal retinal vessel regrowth while suppressing pathological vessel growth.
- SZN-8141 combines Frizzled 4 (Fzd4) agonism and Vascular Endothelial Growth Factor (VEGF) antagonism which has the potential to provide benefits over treatment with single agents for Diabetic Macular Edema (DME) and neovascular Age Related Macular Degeneration (wet AMD)
- SZN-8143: combines Fzd4 agonism, VEGF antagonism, and interleukin-6 (IL-6) antagonism which may have benefits over single agents for treatment of DME/wet AMD/uveitic macular edema (UME)
Product Candidate SZN-113
SZN-113 targets Fzd127 and is in development for Fuchs' Endothelial Corneal Dystrophy (FECD) and Geographic Atrophy (GA).
- FECD preclinical models: SZN-113 enhanced proliferation of primary human corneal endothelial cells in vitro, demonstrated evidence of wound healing in acute corneal endothelial injury models, and rapidly reduced central corneal thickness along with demonstrating improved corneal clarity in a cryoinjury model in mouse and rabbit.
- GA preclinical models: Fzd127 molecules stimulated retinal pigment epithelium cell proliferation and differentiation in culture and provided neuroprotection in acute injury and progressive degeneration models of photoreceptor degeneration.
Corporate Updates
Corporate Partnerships
Surrozen executed a partnership with Boehringer Ingelheim (BI) in the fourth quarter of 2022 to develop a Wnt agonist, SZN-413, for the treatment of people with retinal diseases. In September 2024, Surrozen announced that Boehringer Ingelheim will further develop SZN-413 to advance the compound and prepare it for clinical testing. The milestone achievement triggered a $10 million payment to Surrozen as part of the agreement. This milestone payment was received in October 2024.
Research Collaboration with TCGFB
In November, Surrozen announced a strategic research collaboration with privately-held TCGFB, Inc. ("TCGFB") to discover antibody therapeutics targeting Transforming Growth Factor Beta (TGF-β) for the potential treatment of patients with idiopathic pulmonary fibrosis (IPF). TCGFB will own all TGF-β product related intellectual property. Under the terms of the agreement, Surrozen will provide antibody discovery services for a period of up to two years. In exchange for Surrozen's research services, TCGFB will pay Surrozen up to $6 million in the aggregate, plus any third-party costs, and will issue Surrozen a warrant for up to 3,380,000 shares of TCGFB common stock at an exercise price of $0.0001 per share based on certain vesting conditions.
Financial Results for the Second Quarter Ended September 30, 2024
Cash Position: Cash and cash equivalents were $31.0 million as of September 30, 2024, compared to $37.8 million as of June 30, 2024. In addition, Surrozen received a $10 million milestone payment from BI in October 2024.
Collaboration and License Revenue: Collaboration and license revenue for the third quarter ended September 30, 2024 was $10.0 million, as compared to zero for the same period in 2023. The increase was due to the recognition of a milestone achieved under the collaboration and license agreement with BI in September 2024.
Research and Development Expenses: Research and development expenses for the third quarter ended September 30, 2024 were $5.2 million, as compared to $6.1 million for the same period in 2023.

About SZN-043 for Severe Alcohol-Associated Hepatitis
SZN-043 is the first development candidate using Surrozen's SWEETS™ technology. Surrozen is developing SZN-043 for severe liver diseases, initially focusing on alcohol-associated hepatitis. The Company has completed the Phase 1a clinical trial in patients with chronic liver disease and healthy volunteers. SZN-043 demonstrated acceptable safety and tolerability in all subjects, with evidence of target engagement, Wnt signal activation and effects on liver function. Enrollment is ongoing in the Phase 1b clinical trial in patients with severe alcohol-associated hepatitis. Cohort 1 in the Phase 1b trial completed enrollment in 6 patients with no drug related SAEs. There were no patient deaths at day 30 of the study and the company observed a potential clinical benefit based on reductions in bilirubin and MELD score. A majority of patients experienced improvements in AST and ALT levels. Proof-of-concept data is anticipated in the first half of 2025.
About SZN-413 for Retinal Diseases
SZN-413 is a bi-specific antibody targeting Fzd4-mediated Wnt signaling designed using Surrozen's SWAP™ technology. SZN-413 is being developed for the treatment of retinal vascular-associated diseases. Data generated by Surrozen with SZN-413 in preclinical models of retinopathy demonstrated that SZN-413 could potently stimulate Wnt signaling in the eye, induce normal retinal vessel regrowth, suppress pathological vessel growth and reduce vascular leakage. This novel approach could thus potentially allow for regeneration of healthy eye tissue, not only halting retinopathy, but possibly allowing for a full reversal of the patient's disease.
In the fourth quarter of 2022, Surrozen entered into a strategic partnership with Boehringer Ingelheim for the research and development of SZN-413 for the treatment of retinal diseases. Under the terms of the agreement, Boehringer Ingelheim received an exclusive, worldwide license to develop SZN-413 and other Fzd4-specific Wnt-modulating molecules for all purposes, including as a treatment for retinal diseases, in exchange for an upfront payment to Surrozen of $12.5 million. Surrozen will also be eligible to receive up to $587.0 million in success-based development, regulatory, and commercial milestone payments, in addition to mid-single digit to low-double digit royalties on sales. After an initial period of joint research, Boehringer Ingelheim will assume all development and commercial responsibilities.
In September 2024, Surrozen announced that Boehringer Ingelheim will further develop SZN-413 to advance the compound and prepare it for clinical testing. The milestone achievement triggered a $10 million payment to Surrozen as part of the agreement.
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
