Askgene Pharma Inc., which less than two weeks ago reported positive initial data from an ongoing phase I/II trial testing its claudin 18.2-targeting candidate, ASKB-589, added $20 million in a series A round, intended to advance the company’s clinical pipeline and support further development of its Smartkine cytokine drug platform.
Kodiak Sciences Inc. shares (NASDAQ:KOD) closed at $9.86, down $40.49, or 80.42% after the firm unveiled top-line data from its randomized, double-masked, active comparator-controlled phase IIb/III trial testing KSI-301, an antibody biopolymer conjugate, in treatment-naïve subjects with wet age-related macular degeneration (AMD).
Curacle Co. Ltd. is training its sights on more partnerships after nabbing a licensing and collaboration agreement with Théa Open Innovation, a subsidiary of Laboratoires Théa SAS. The deal, for CU06-RE, Curacle’s oral treatment for diabetic macular edema and wet age-related macular degeneration (wet-AMD), includes $6 million up front for Curacle and as much as $157.5 million in potential development, regulatory and sales milestones, as well as royalties on sales.
Biogen Inc. and Samsung Bioepis Co. Ltd. gained FDA clearance for Byooviz (ranibizumab-nuna), a biosimilar that references the VEGF therapy Lucentis (ranibizumab) from Roche Holding AG, as a treatment for wet age-related macular degeneration, macular edema following retinal vein occlusion and myopic choroidal neovascularization. Byooviz is the first ophthalmology biosimilar to win the go-ahead in the U.S., and was approved in the EU on Aug. 18, 2021, followed by the U.K. on Aug. 31, 2021.
Abbvie Inc. and Regenxbio Inc. have announced a partnership to develop and commercialize RGX-314, a potential one-time gene therapy for the treatment of wet age-related macular degeneration (wet AMD), diabetic retinopathy and other chronic retinal diseases. Under the terms of the agreement, Abbvie will pay Regenxbio $370 million up front, plus up to $1.38 billion in additional development, regulatory and commercial milestones. The deal gives '314 – already the most advanced gene therapy in wet AMD – another potential edge against its nearest competitor, Adverum Biotechnologies Inc.’s ADVM-022.
Visus Therapeutics Inc. has expanded its ophthalmic drug portfolio, in-licensing investigational therapies for glaucoma and age-related macular degeneration from Cella Therapeutics LLC, which will be developed by Finland’s Delsitech Ltd. using its extended-release depot technology.
Adverum Biotechnologies Inc. CEO Laurent Fischer said the firm chose the more prudent route in scrapping development of gene therapy ADVM-022 (AAV.7m8-aflibercept) for diabetic macular edema (DME) as a result of dose-limiting toxicity in the phase II Infinity trial.
At the end of March, JAMA Ophthalmology’s publication of first results from the NIH-sponsored, 328-patient trial with Regeneron Pharmaceuticals Inc.’s VEGF inhibitor, Eylea (aflibercept), in non-proliferative diabetic retinopathy bolstered investor hopes for wider use. But competitors loom for the compound, first approved in November 2011 for wet age-related macular degeneration.
Graybug Vision Inc. reported results from the phase IIb Altissimo study testing GB-102 as a treatment for wet age-related macular degeneration (AMD) that didn't live up to expectations set by the phase I/IIa Adagio study.
The 2017 FDA approval of Luxturna (voretigene neparvovec-rzyl, Roche Holding AG) spurred a race to create the next gene therapy for the eye. The organ is very amenable to gene therapy given that it's a confined space with post-mitotic cells that has immune privilege and requires substantially smaller amounts of viral vector compared to systemic treatments.
