Surrozen, Inc. is a clinical stage biotechnology company, which engages in the business of discovering and developing drug candidates to selectively modulate the Wnt pathway, a critical mediator of tissue repair, in a broad range of organs and tissues. The company is headquartered in South San Francisco, California and currently employs 40 full-time employees. The company went IPO on 2020-11-23. The firm is developing tissue-specific antibodies designed to engage the body’s existing biological repair mechanisms with a focus in ophthalmology. Its product candidates include SZN-8141 for Retinal Diseases, SZN-8143 for Retinal Diseases, SZN-113 for Fuchs’ Endothelial Corneal Dystrophy and Geographic Atrophy, and SZN-413 for Retinal Diseases. 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. SZN-413 is a bi-specific antibody, designed using its SWAP technology.
