Part 1a trial of SZN-043 demonstrated proof of goal engagement and Wnt-pathway mediated pharmacodynamic results within the liver
Enrollment is ongoing in Part 1b examine in extreme alcohol-associated hepatitis
Surrozen Inc. (“Surrozen” or the “Firm”) (Nasdaq: SRZN), an organization pioneering focused therapeutics that selectively activate the Wnt Pathway for tissue restore and regeneration, offered a poster on the preliminary outcomes of a Part 1a examine of SZN-043, a novel R-Spondin mimetic, in wholesome volunteers and topics with liver cirrhosis on June 8, 2024 on the 2024 European Affiliation for the Research of the Liver (EASL) in Milan (LINK: HERE ).
Research Overview
- Secure and well-tolerated doses of SZN-043 have been established within the randomized, placebo-controlled, first-in-human, Part 1a trial in 40 wholesome volunteers (HVs) and eight sufferers with a historical past of liver cirrhosis.
- Single or a number of intravenous infusion doses have been administered in a spread from 0.5 mg/kg to three mg/kg.
- In some handled topics, there have been mild-to-moderate, transient, and dose-related serum transaminase elevations that resolved with out intervention. These serum transaminase elevations weren’t related to different adjustments in medical pathology which might be indicative of liver illness or bile duct harm.
Pharmacodynamic Biomarkers
The examine offered proof of Wnt-mediated pharmacodynamic exercise within the liver after therapy with SZN-043.
- Goal engagement was confirmed through transient will increase in alkaline phosphatase (ALP). Will increase in ALP are indicative of SZN-043 binding to, and elimination of, its focusing on receptor asialoglycoprotein (ASGPR) from the floor of the hepatocytes and this discount in its capability to clear ALP is in step with observations in different ASGPR binding brokers.
- Wnt sign activation was demonstrated by the outcomes of the methacetin breath check. This check confirmed elevated methacetin clearance following SZN-043 administration which is indicative of activation of the Wnt goal gene, CYP1A2, in hepatocytes.
- HepQuant measurements demonstrated will increase within the portal hepatic filtration charge (HFR). The HepQuant check is a quantitative liver operate check that measures cholate clearance to evaluate liver operate. The rise in portal HFR is regarded as associated to Wnt-mediated induction of cholate clearance by SZN-043.
“We have been happy to current the primary medical information from this progressive bispecific antibody-based method to modulating the Wnt pathway. The Part 1a examine demonstrated activation of Wnt signaling, goal engagement within the liver, the preliminary results noticed on liver operate and that the drug was protected and properly tolerated,” mentioned Craig Parker, President and Chief Government Workplace of Surrozen. “We’re making important progress with our platform applied sciences as we deal with optimizing our talents to modulate the Wnt pathway and supply essential new therapeutic choices by means of focused cell and tissue regeneration. Wnt modulation in hepatocytes is a promising new mechanism for supporting regeneration in injured livers.”
About SZN-043 for Extreme Alcohol-Related Hepatitis
SZN-043 is the primary improvement candidate utilizing Surrozen’s SWEETS™ know-how. Surrozen is creating SZN-043 for extreme liver illnesses, initially specializing in extreme alcohol-associated hepatitis. The Firm has accomplished a Part 1a medical trial in sufferers with a historical past of liver cirrhosis and wholesome volunteers. SZN-043 was protected and properly tolerated in single or a number of IV doses and demonstrated proof of goal engagement, Wnt sign activation and results on liver operate.
The Part 1b medical trial in sufferers with extreme alcohol-associated hepatitis started enrollment within the second quarter of 2024 and the Firm expects that proof-of-concept information from this trial could also be obtainable within the first half of 2025. The examine will enroll as much as 30 sufferers with extreme alcohol-associated hepatitis in an open-label trial. The examine will consider security, pharmacokinetics, immunogenicity and plenty of efficacy endpoints together with MELD rating, Lille rating and survival. The MELD and Lille scores have been proven to correlate with medical enchancment and 90-day survival.
About SZN-413 for Retinal Ailments
SZN-413 is a bi-specific antibody focusing on Fzd4-mediated Wnt signaling designed utilizing Surrozen’s SWAP™ know-how. It’s at the moment being developed for the therapy of retinal vascular-associated illnesses. Information generated by Surrozen with SZN-413 in preclinical fashions of retinopathy demonstrated that SZN-413 may potently stimulate Wnt signaling within the eye, induce regular retinal vessel regrowth, suppress pathological vessel progress and scale back vascular leakage. This novel method may thus doubtlessly permit for regeneration of wholesome eye tissue, not solely halting retinopathy, however presumably permitting for a full reversal of the affected person’s illness.
Within the fourth quarter of 2022, Surrozen entered right into a strategic partnership with Boehringer Ingelheim for the analysis and improvement of SZN-413 for the therapy of retinal illnesses. Below the phrases of the settlement, Boehringer Ingelheim acquired an unique, worldwide license to develop SZN-413 and different Fzd4-specific Wnt-modulating molecules for all functions, together with as a therapy for retinal illnesses, in change for an upfront fee to Surrozen of $12.5 million. Surrozen may also be eligible to obtain as much as $587.0 million in success-based improvement, regulatory, and business milestone funds, along with mid-single digit to low-double digit royalties on gross sales. After an preliminary interval of joint analysis, Boehringer Ingelheim will assume all improvement and business tasks.
About Wnt Signaling
Wnt signaling performs key roles within the management of improvement, homeostasis, and regeneration of many important organs and tissues, together with liver, gut, lung, kidney, retina, central nervous system, cochlea, bone, and others. Modulation of Wnt signaling pathways has potential for therapy of degenerative illnesses and tissue accidents. Surrozen’s platform and proprietary applied sciences have the potential to beat the constraints in pursuing the Wnt pathway as a therapeutic technique.
About Surrozen
Surrozen is a medical stage biotechnology firm discovering and creating drug candidates to selectively modulate the Wnt pathway. Surrozen is creating tissue-specific antibodies designed to have interaction the physique’s present organic restore mechanisms with a present deal with extreme liver and eye illnesses.
