Enrollment ongoing in SZN-043 Phase 1b trial in patients with Severe Alcoholic Hepatitis Presented first-in-human data from SZN-043 Phase 1a trial at EASL Published study that demonstrated application of unique Targeted Protein Degradation technologies resulting in robust Wnt signal activation in bispecific antibodies based on the Company's SWEETS technology platform SOUTH SAN FRANCISCO, Calif., Aug. 12, 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 second quarter 2024 financial results and business updates. “We made significant progress in the second quarter with accomplishment of key milestones including dosing the first patient in the SZN-043 Phase 1b trial, presenting first-in-human data from the SZN-043 Phase 1a trial at EASL and publishing new information regarding the promise of our proprietary SWEETS platform,” said Craig Parker, President and Chief Executive Officer of Surrozen. “Surrozen is focused on transforming the treatment of severe diseases of the liver and eye, and we look forward to proof-of-concept data from the SZN-043 Phase 1b clinical trial in the first half of 2025.” Research and Development Pipeline Highlights SZN-043Surrozen is developing SZN-043 for severe liver disease with an initial focus in severe alcohol-associated hepatitis. Clinical Development Milestones and Medical Meeting Presentation Enrollment initiated and ongoing in Phase 1b trial; proof-of-concept data is anticipated in the first half of 2025Presented Phase 1a trial results at 2024 European Association for the Study of the Liver (EASL) in June 2024 (LINK: HERE) Treatment with SZN-043 was safe and well tolerated in healthy volunteers and patients with a history of liver cirrhosisResults demonstrated evidence of target engagement and Wnt-pathway mediated pharmacodynamic effects in the liver Research Programs Publications Surrozen published study in eLife (LINK: HERE) describing development of two new ASGR bispecific antibodies that resulted in a robust and cell specific boost to Wnt-signaling through protein degradation technologies These ASGR-targeted SWEETS (Surrozen Wnt Signal Enhancer Engineered for Tissue Specificity) molecules represent a unique targeted protein degradation (TPD) platform, that functions via multiple mechanisms, and expands the potential opportunities to treat liver diseases through cell or tissue-specific regenerative therapeutics with enhanced Wnt signal activation Surrozen published a review article in iScience (LINK: HERE) that provided a comprehensive summary of work done in the field on invention of various Wnt activating platforms and highlighted the rationales and design rules described so far in this emerging field including the potential for Wnt agonists in the treatment of numerous tissue degenerative diseases Corporate Updates Corporate PartnershipsSurrozen 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. We anticipate the potential to nominate the lead Fzd-4 targeted Wnt agonist development candidate in 2024, which would trigger a $10.0 million milestone payment to the Company. Financial Results for the Second Quarter Ended June 30, 2024 Cash Position: Cash and cash equivalents were $37.8 million as of June 30, 2024, compared to $27.3 million as of March 31, 2024. Research and Development Expenses: Research and development expenses for the second quarter ended June 30, 2024 were $5.3 million, as compared to $6.9 million for the same period in 2023. The decreases were primarily due to the restructuring executed in 2023 to prioritize and focus our resources on clinical stage programs, as well as the discontinuation of the clinical development of SZN-1326. Research and development expenses include non-cash stock-based compensation expenses of $0.4 million for the second quarter ended June 30, 2024, as compared to $0.3 million for the same period in 2023. General and Administrative Expenses: General and administrative expenses for the second quarter ended June 30, 2024 were $3.7 million, as compared to $3.3 million for the same period in 2023. The increase was primarily a result of the employee retention tax credits received in 2023. General and administrative expenses include non-cash stock-based compensation expenses of $0.8 million for the second quarter ended June 30, 2024 and the same period in 2023. Interest Income: Interest income for the second quarter ended June 30, 2024 was $0.5 million, as compared to $0.6 million for the same period in 2023. The decrease was primarily related to the decrease in our money market funds and marketable securities. Other Income, Net: Other income, net for the second quarter ended June 30, 2024 was $3.7 million, as compared to $0.3 million for the same period in 2023. The increase was primarily related to a $4.8 million increase in the non-cash change in fair value of warrant liabilities, offset by $1.5 million related to the transaction costs allocated to the warrants issued in a private placement. Loss on Issuance of Common Stock, Pre-Funded Warrants and Warrants: Loss on issuance of common stock, pre-funded warrants and warrants for the second quarter ended June 30, 2024 was $20.4 million, as compared to zero for the same period in 2023. The increase was due to the fair value of pre-funded warrants and warrants issued greater than the proceeds received in a private placement. Net Loss: Net loss for the second quarter ended June 30, 2024 was $25.3 million, as compared to $9.4 million for the same period in 2023. About SZN-043 for Severe Alcohol-Associated HepatitisSZN-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 a 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 and proof-of-concept data from this trial is anticipated in the first half of 2025. About SZN-413 for Retinal DiseasesSZN-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. About Wnt SignalingWnt 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 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 a current focus on severe liver and eye diseases.
