SHANGHAI, Sept. 4, 2024 /PRNewswire/ -- YolTech Therapeutics, a clinical-stage in vivo gene editing company, announced that the U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation (ODD) to YOLT-203 for the treatment of primary hyperoxaluria type 1 (PH1) in September. Earlier that month, YOLT-203 received Rare Pediatric Disease Designation (RPDD) from the FDA. After reviewing YolTech's submission, the FDA determined that the therapy is not only appropriate for primary hyperoxaluria type 1 (PH1), but also applicable to the broader category of primary hyperoxaluria (PH). As a result, the designations were granted for PH, reflecting the expanded scope of the therapy's potential impact. These dual designations underscore the transformative potential of YOLT-203 to address this rare and life-threatening genetic disorder. About Primary Hyperoxaluria and PH1 Primary hyperoxaluria (PH) is a rare autosomal recessive genetic disorder in which excessive oxalate production in the liver causes kidney stone formation, progressive renal damage, and systemic oxalosis. The most common subtype of PH, primary hyperoxaluria type 1 (PH1), results from dysfunction of alanine-glyoxylate aminotransferase (AGT) due to mutations in the AGXT gene. In the absence of intervention, most patients progress to end-stage renal disease (ESRD), requiring intensive hemodialysis and often a dual liver-kidney transplant to correct the metabolic defect and address organ failure. About YOLT-203 YOLT-203 is an innovative investigational in vivo gene editing therapy designated to provide a one-time, potentially curative treatment for primary hyperoxaluria type 1 (PH1). YOLT-203 permanently reduces excessive oxalate production in PH1 by deactivating the HAO1 gene through YolTech's proprietary YolCas12™ system, a novel CRISPR/Cas enzyme identified through the High-Throughput Evolution Platform (HEPDONE®). YOLT-203 is administered through intravenous infusion of liver-targeted lipid nanoparticles (LNPs) encapsulating YolCas12 mRNA and a guide RNA (gRNA) targeting the HAO1 gene. YOLT-203 also represents a historic milestone as the first in vivo gene editing therapy to enter clinical trial globally for a pediatric rare disease. Clinical Development and Early Results The investigator-initiated clinical study of YOLT-203 began on August 5, 2024, with the first adult patient dosed, followed by the first pediatric patient on August 20, 2024. Early data from preclinical and initial clinical studies have demonstrated promising reductions of over 90% in blood oxalate levels, with no dose-limiting toxicities (DLTs) or severe adverse events (SAEs) leading to treatment interruptions observed to date. Significance of FDA Designations The Rare Pediatric Disease Designation (RPDD) program encourages the development of new drugs and biologics for rare pediatric conditions. This designation makes YolTech eligible to receive a priority review voucher (PRV) upon potential FDA approval of YOLT-203. Similarly, the Orphan Drug Designation (ODD) program provides benefits including tax credits, exemption from certain FDA fees, and seven years of market exclusivity upon regulatory approval. About YolTech Therapeutics YolTech Therapeutics is a clinical-stage in vivo gene editing company committed to pioneering the next generation of precision genetic medicines. Our approach combines innovative gene editing technologies with an advanced lipid nanoparticle (LNP) delivery system, creating a versatile platform designed to address a wide range of serious diseases.

Dec. 19, 2024 -- Arbor Biotechnologies™, a biotechnology company discovering and developing the next generation of genetic medicines, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for ABO-101, a novel gene editing therapeutic designed to address primary hyperoxaluria type 1 (PH1). The redePHine Phase 1/2 study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of ABO-101 in both adult and pediatric patients with PH1. “We are thrilled to advance ABO-101 to the clinic as we believe it has the potential to be a first-in-class treatment for PH1, a rare disease with a high unmet need, and reinforces the promise of our precisely tailored gene editing approach,” said Dan Ory, M.D., Chief Medical Officer of Arbor. “ABO-101 is supported by a strong suite of preclinical data demonstrating specific and durable in vivo editing of HAO1 and corresponding, therapeutically relevant reductions in urinary oxalate in PH1 disease models.” ABO-101 is a liver-targeted gene editing therapeutic in development for the treatment of primary hyperoxaluria type 1 (PH1). PH1 is a rare genetic disorder in which enzyme deficiencies in the liver lead to the overproduction and buildup of oxalate, resulting in kidney stones eventually leading to end stage kidney disease and systemic oxalosis. ABO-101 is designed to knock down HAO1 gene expression in the liver, thereby providing durable reduction in oxalate production. “The FDA approval of the ABO-101 IND marks a significant milestone for the hyperoxaluria community. At OHF, we are committed to partnering with industry leaders to advance care, research, and patient-focused drug development for hyperoxaluria. Arbor’s innovative CRISPR-based approach represents a groundbreaking opportunity in genomic medicine, with the potential to transform the lives of patients with PH1,” said Kim Hollander, Executive Director of The Oxalosis and Hyperoxaluria Foundation. “The initiation of this study marks an important milestone both for patients with PH1 and in the growth of our company as we begin advancing our pipeline of first-in-class programs into the clinic,” said Devyn Smith, CEO of Arbor. “There is a tremendous need for innovative approaches to treat genetic conditions – from ultra-rare to the most common genetic diseases – and we’re excited for the potential of our next-generation genetic medicines that can address a vast spectrum of devastating diseases. I applaud the hard work of our team at Arbor for getting us to this stage.” ABO-101 is a novel, investigational gene editing medicine designed to be a one-time treatment that results in a permanent loss of function of the HAO1 gene in the liver to reduce PH1-associated oxalate production. ABO-101 consists of a lipid nanoparticle (LNP), licensed from Acuitas Therapeutics, encapsulating messenger RNA expressing a novel Type V CRISPR Cas12i2 nuclease and an optimized guide RNA which specifically targets the human HAO1 gene. Arbor Biotechnologies™, a next-generation gene editing company based in Cambridge, MA, is advancing a pipeline of novel gene editing therapeutics to address a wide range of genetic conditions – from the ultra-rare to the most common genetic diseases. The company’s unique suite of optimized gene editors goes beyond the limitations of early editing technologies to unlock access to new gene targets and has fueled a robust pipeline of first-in-class assets focused on diseases of high unmet need. With Arbor’s lead program, ABO-101 for the treatment of primary hyperoxaluria type 1, progressing into clinical trials, the company continues to focus their research and development efforts on genomic diseases of the liver and CNS for which there are no existing functional cures.
