AbstractBackgroundWnt/β-catenin signaling is critical for lung development and AT2 stem cell maintenance in adults, but excessive pathway activation has been associated with pulmonary fibrosis, both in animal models and human diseases such as idiopathic pulmonary fibrosis (IPF). IPF is a detrimental interstitial lung disease, and although two approved drugs limit functional decline, transplantation is the only treatment that extends survival, highlighting the need for regenerative therapies.MethodsUsing our antibody-based platform of Wnt/β-catenin modulators, we investigated the ability of a pathway antagonist and pathway activators to reduce pulmonary fibrosis in the acute bleomycin model, and we tested the ability of a WNT mimetic to affect alveolar organoid cultures.ResultsA WNT mimetic agonist with broad FZD-binding specificity (FZD1,2,5,7,8) potently expanded alveolar organoids. Upon therapeutic dosing, a broad FZD-binding specific Wnt mimetic decreased pulmonary inflammation and fibrosis and increased lung function in the bleomycin model, and it impacted multiple lung cell types in vivo.ConclusionsOur results highlight the unexpected capacity of a WNT mimetic to effect tissue repair after lung damage and support the continued development of Wnt/β-catenin pathway modulation for the treatment of pulmonary fibrosis.

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. The Company is in the process of initiating enrollment in the Phase 1b clinical trial in patients with severe alcohol-associated hepatitis and expects that proof-of-concept data from this trial may be available 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. It is currently 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.

Surrozen's Wnt mimetic antibody improves lung function in mice with pulmonary fibrosis

In mice with idiopathic pulmonary fibrosis, twice-weekly injections of Surrozen's molecule for two and a half weeks decreased lung fibrosis, reduced inflammation and improved lung function compared to controls. A Wnt/β-catenin pathway agonist under development by Surrozen appears to be effective against idiopathic pulmonary fibrosis (IPF) in mouse models, according to new data. The results, published April 2 in the journal Respiratory Research, are an early signal of a potential new indication for the company’s SWAP technology. “Current treatments for severe lung disease like IPF aren’t able to regenerate normal, functional tissue,” Yang Li, Ph.D., executive vice president of research at Surrozen, said in a press release. “This work … represents a breakthrough in understanding the role of the Wnt pathway in lung fibrosis and the potential for Wnt mimetics to reduce fibrosis and improve lung function.” IPF is a condition where scar tissue builds up in the lungs, making it difficult to breathe. It occurs in about 13 to 20 in every 100,000 people globally, most of them between the ages of 50 and 70. IPF is sporadic and doesn’t have a clear cause, though there are a handful of linked gene mutations and known risk factors. The latter include smoking, exposure to wood or metal dust and some drugs such as certain antibiotics, heart medications and cancer therapies. The Wnt/B-catenin signaling pathway is a group of proteins that are heavily involved in tissue development and maintenance, including in the lungs. Prior to the new study, it wasn’t clear whether activating the pathway was helpful or harmful in IPF, as there was some evidence that genes associated with its activation were elevated in patient tissue samples and mouse models, the researchers noted in the article. On the other hand, a type of stem cell found in the lungs requires Wnt signaling activity for cell maintenance and renewal, and research in mice suggested that activating the pathway decreases lung inflammation. After demonstrating in mice that activating the pathway was more beneficial against IPF than suppressing it, Surrozen researchers tested out a molecule called a Wnt mimetic antibody, which mirrors the effects of proteins involved in Wnt pathway signaling. In mice with IPF, twice-weekly injections of the molecule for two and a half weeks decreased lung fibrosis, reduced inflammation and improved lung function compared to controls. The antibody's benefits appeared to come from its activity on several different types of cells, including cells of the alveoli—the tiny air sacs in the lungs—as well as stromal and immune cells. “Our findings suggest there is great potential for modulating Wnt/B-catenin signaling to treat lung diseases including IPF—a possibility warranting more thorough explanation,” the researchers wrote in the article. They plan to continue to develop Wnt mimics that target specific cell types, which would enable therapies with a lower risk of systemic side effects. Surrozen’s focus on the Wnt pathway has yielded two candidates so far: SZN-043 for alcohol-associated hepatitis and SZN-413 for retinal disease. The company had also been developing another drug, SZN-1326, for inflammatory bowel disease but halted that program in January due to side effects. SZN-043 is currently being tested in a phase 1b trial, for which the company may have data in the second half of 2024. For SNZ-413, which is being co-developed with Boehringer Ingelheim, the biotech announced April 1 that it had completed a phase 1a trial and was in the process of initiating phase 1b.

Surrozen Publishes Study in 'Respiratory Research' Demonstrating the Promise of a Wnt Mimetic Antibody in Treating Pulmonary Fibrosis

In a preclinical model of pulmonary fibrosis, a Surrozen antibody-based SWAP platform molecule decreased pulmonary inflammation and fibrosis and improved lung function Surrozen Wnt mimetic SWAP molecules also expanded alveolar organoid cultures and impacted multiple lung cell types in vivo Results highlight the potential of Wnt mimetic agonists to repair tissue after damage in severe lung diseases like idiopathic pulmonary fibrosis SOUTH SAN FRANCISCO, Calif., April 03, 2024 (GLOBE NEWSWIRE) -- Surrozen, Inc. (Nasdaq: SRZN), a company pioneering targeted therapeutics that selectively modulate the Wnt pathway for tissue repair and regeneration, announced today publication of data in Respiratory Research highlighting the potential for Surrozen’s Wnt mimetic technologies to treat serious lung diseases like idiopathic pulmonary fibrosis (IPF) https://respiratory-research-biomedcentral-com.libproxy1.nus.edu.sg/articles/10.1186/s12931-024-02786-2. The results observed with systemic administration of Surrozen’s Wnt mimetic antibody in an acute bleomycin model of pulmonary fibrosis demonstrate a Wnt pathway mediated decrease in inflammation and fibrosis and improvement in lung function. Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease characterized by areas of myofibroblast accumulation and extracellular matrix (ECM) deposition, disruption of alveolar architecture, and restricted lung physiology. In pulmonary fibrosis, multiple cell types may need to be targeted to provide a regenerative environment facilitating repair. Mechanisms that stimulate expansion of certain beneficial cell types in the lung which also limiting expansion of fibrosis promoting cell types and of pro-inflammatory cells may be desirable. The canonical Wnt/β-catenin signaling pathway plays an important role in the lung alveolar epithelium. During development this pathway is critical for the establishment of alveoli. In adult lungs, a subset of alveolar type 2 (AT2) cells are stem cells, and Wnt/β-catenin signaling is required for AT2 cell maintenance and renewal under both normal and injured conditions. Furthermore, activation of Wnt signaling has been found to have an anti-inflammatory effect on macrophages in several mouse lung damage models. “Current treatments for severe lung diseases like IPF aren’t able to regenerate normal, functional tissue,” said Yang Li, Ph.D., Executive Vice President, Research at Surrozen. “This work published in Respiratory Research represents a breakthrough in understanding the role of the Wnt pathway in lung fibrosis and the potential for Wnt mimetics to reduce fibrosis and improve lung function.” About SZN-043 for Severe Alcohol-Associated HepatitisSZN-043 is the first development candidate using Surrozen’s SWEETS™ technology.
