Surrozen (NasdaqCM:SRZN) 2026 Conference Transcript

Surrozen (NasdaqCM:SRZN) Conference Call Summary Company Overview - Surrozen is a biotech company founded in 2016, focusing on Wnt biology and antibody engineering, particularly in retinal diseases [3][4] Core Points and Arguments Wnt Pathway and Retinal Diseases - The Wnt pathway is critical for the development and maintenance of various tissues, including the eye [3] - Surrozen is targeting the Fzd4 receptor, which is essential for normal retinal vessel function [4] - Diseases associated with the loss of function of the Wnt pathway include rare conditions like Norrie Disease and FEVR, but the focus is on more prevalent retinal vascular diseases such as diabetic macular edema (DME) and wet age-related macular degeneration (AMD) [6][7] Competitive Landscape - Surrozen's lead molecule is positioned against competitors like Merck, which has a similar pharmacological approach and is currently in Phase III trials [6][7][29] - The current market is dominated by Roche's Vabysmo and Eylea, which are anti-VEGF therapies [29] Mechanism of Action - Surrozen's approach involves activating the Wnt pathway to restore normal vessel architecture and function, contrasting with existing therapies that inhibit pathological factors like VEGF [17][20] - Activation of the Wnt pathway is shown to upregulate tight junction proteins, which help seal leakage in retinal endothelial cells, particularly relevant in DME [19][20] Clinical Development - Surrozen has three programs: two internal molecules (8141 and 8143) and one partnered with Boehringer Ingelheim (SZN-413) [27][82] - The IND for molecule 8141 is expected to clear in 2026, with ongoing IND-enabling work [41][61] - Molecule 8141 is a bispecific tetravalent antibody targeting Wnt and VEGF, while 8143 adds IL-6 inhibition, making it trifunctional [71][72] Upcoming Milestones - The first Phase III trial data for Merck's molecule is expected in September 2026, which could validate the Wnt pathway's role in treating retinal diseases [75] - Surrozen anticipates updates on the IND timelines and further details on clinical trial designs soon [70][88] Intellectual Property and Financial Health - Surrozen has a robust patent estate with approximately 38 applications, focusing on multivalent Frizzled and LRP5/6 binding antibodies [89] - The company completed a PIPE in March 2025, raising $175 million, with $80 million in cash reported at the end of Q3 2025 [90] Other Important Information - The partnership with Boehringer Ingelheim has yielded $22.5 million, with hopes for clinical advancement of SZN-413 [82][85] - Roche's acquisition of Frizzled and LRP binders from University of Toronto is noted, but no updates on their progress have been provided [87] This summary encapsulates the key points discussed during the conference call, highlighting Surrozen's strategic focus, competitive positioning, and future milestones in the context of retinal disease treatment.
