Attention has turned to the regulatory path worldwide after Belite Bio Inc. unveiled positive top-line data from the phase III Dragon study with oral, daily tinlarebant in Stargardt disease type 1, the most common form of the rare affliction.
The U.S. FDA has cleared Aavantgarde Bio Srl’s IND application for AAVB-039, the company’s gene therapy program for Stargardt disease, the most common inherited form of macular degeneration.
Three months after dosing the first patient with its dual vector gene therapy, Splicebio SL has closed a $135 million series B to fund the phase I/II trial of SB-007 in the treatment of Stargardt’s disease to completion. Other adeno-associated viru gene therapies for the inherited retinal disorder have entered the clinic, but SB-007 is the first with the capacity to deliver a full version of the ABCA4 gene that underlies Stargardt’s.
Inherited retinal dystrophies (IRDs), including retinitis pigmentosa and Stargardt disease, are a group of rare degenerative disorders of the retina with clinical and genetic heterogeneity. In a recent publication, researchers from the Institute of Ocular Microsurgery applied clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 and transcription activator-like effector nucleases (TALEN) gene-editing tools to precisely correct induced pluripotent stem cell (hiPSC) lines derived from IRD patients.
Stargardt disease, the most common form of juvenile macular degeneration, results from biallelic mutations in the ABCA4 gene. In a recently published study, researchers at the Institute of Molecular and Clinical Ophthalmology Basel and collaborators proposed a novel dual AAV vector system to deliver a split-intein adenine base editor for precise correction of the most common Stargardt mutation, c.5882G>A (p.Gly1961Glu).
Vigeneron GmbH has received IND approval from the FDA for VG-801, a novel mRNA trans-splicing gene therapy to treat Stargardt disease and other retinal dystrophies associated with mutations in the ABCA4 gene. IND clearance enables initiation of a phase I/II trial, with a clinical trial application (CTA) submission to the EMA also planned in the coming months.
Splicebio S.L. has gained IND clearance from the FDA for its lead program SB-007, a protein splicing gene therapy to address the root genetic cause of Stargardt disease.
Ascidian Therapeutics Inc. recently provided preclinical data for ACDN-01, an AAV-encoded RNA exon editor targeting ABCA4, being developed for the treatment of ABCA4-related retinopathies, including Stargardt disease.
From glaucoma to Stargardt disease, age-related macular degeneration (AMD) to retinitis pigmentosa, or a corneal transplant to Bietti’s crystalline dystrophy, the 27th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) is working to bring some light to patients with age and congenital diseases that affect vision. From May 7-11, 2024, thousands of scientists are gathering in Baltimore to show their advances against the challenges of delivering genes and cells to the correct place, avoiding immunogenicity and improving diseases.
At the recently concluded ARVO meeting, Splicebio S.L. presented the first preclinical results on the company’s new candidate, SB-007, for the treatment of Stargardt disease, a rare genetic disease caused by mutations in the ABCA4 gene with no approved treatment on the market.
