CHARLESTOWN, Mass., March 07, 2024 (GLOBE NEWSWIRE) -- Solid Biosciences Inc. (Nasdaq: SLDB), a life sciences company developing precision genetic medicines for neuromuscular and cardiac diseases, today announced a non-exclusive worldwide license and collaboration agreement with Armatus Bio for the use of Solid’s proprietary capsid AAV-SLB101 for the development and commercialization of Armatus’ vectorized RNAi candidate to treat Facioscapulohumeral muscular dystrophy (FSHD). The AAV-SLB101 capsid has been shown in preclinical studies to have enhanced biodistribution and improved expression in muscle cells.
Under the terms of the agreement, Solid granted Armatus a non-exclusive worldwide license to utilize AAV-SLB101 for treatment of FSHD and will provide Armatus AAV-SLB101 plasmid material, preclinical data characterizing AAV-SLB101, and manufacturing and regulatory know-how to enable development. In return, Solid will receive an upfront payment, payments upon the achievement of certain development and sales milestones, and tiered royalties on net sales for any products incorporating AAV-SLB101. Armatus will be responsible for the development and commercialization of licensed products incorporating AAV-SLB101.
“Our transaction with Armatus Bio is the first of what we intend to be a broad out-licensing of our capsid library to both companies and academic institutions. We designed AAV-SLB101 for enhanced biodistribution to skeletal muscle, which is intended to help improve the efficacy and reduce the toxicity of AAV-delivered gene therapies for muscular disorders,” said Bo Cumbo, President and Chief Executive Officer at Solid Biosciences. “AAV-SLB101 is the capsid for our next-generation Duchenne candidate, SGT-003, and we are excited to expand AAV-SLB101’s use to FSHD through this agreement with Armatus Bio.”
Armatus is developing ARM-201, a potential best-in-class, single dose therapeutic used for the treatment of FSHD, a progressive genetic neuromuscular disorder caused by DUX4 overexpression. ARM-201’s proprietary miRNA payload seeks to reduce DUX4, and thus arrest muscle weakening and atrophy, prevent further degeneration, and ameliorate the amount of inflammation and oxidative stress caused by FSHD.
“The use of Solid’s unique AAV-SLB101 capsid will help enable optimal patient dosing for our FSHD program. The preclinical data presented to date for AAV-SLB101 demonstrate increased muscle transduction while simultaneously reducing biodistribution in the liver. These data, combined with the data we have generated for ARM-201 give us high confidence in the potential to reduce total AAV dose levels compared to first generation capsids,” commented Brian Price, Ph.D., Chief Technology Officer at Armatus Bio. “Further, we are encouraged by the strong safety profile demonstrated by AAV-SLB101, which has a cleared IND as the capsid in Solid’s SGT-003 construct for the treatment of DMD. With this license in place, we are eager to advance our optimized ARM-201 construct as the lead candidate toward clinical evaluation.”
About AAV-SLB101
AAV-SLB101 is a proprietary, rationally designed capsid developed for enhanced muscle tropism and reduced liver uptake. With a robust preclinical package in mice and nonhuman primates, AAV-SLB101 has demonstrated increased transduction speed, enhanced skeletal and cardiac muscle tropism, decreased liver biodistribution and improved efficiency when compared to first generation capsids. The incorporation of AAV-SLB101 into AAV delivered therapies has the potential to be a step forward in the treatment of neuromuscular and cardiac diseases. Solid Biosciences aims to license AAV-SLB101 broadly to both companies and academic institutions pursuing treatments for rare diseases.
