About Alltrna Alltrna is the first clinical-stage biotech company advancing tRNA medicines to address shared disease-causing mutations across many indications. The company’s initial therapeutic programs are designed to restore full-length protein production in diseases caused by premature termination codons (PTCs), collectively referred to as Stop Codon Disease, which affect approximately 10% of people with a rare genetic disease. Alltrna’s led program, AP003, is a chemically modified, engineered tRNA oligonucleotide encapsulated in a clinically validated, liver-directed lipid nanoparticle. AP003 is being developed for the arginine-to-TGA (Arg-TGA) PTC in patients with liver Stop Codon Disease, including phenylketonuria, organic acidemias, and urea cycle disorders. Founded in 2018 by Flagship Pioneering, Alltrna has built an integrated platform to design, optimize, and deliver engineered tRNA therapeutics.
