IONS
Ionis Pharmaceuticals develops RNA-targeted medicines to treat serious genetic and neurological diseases. The company has transitioned to a fully integrated commercial-stage biotech with seven marketed medicines, including SPINRAZA for spinal muscular atrophy, WAINUA for hereditary transthyretin amyloidosis, QALSODY and TEGSEDI for ALS, and DAWNZERA for hereditary angioedema, among others. Most of these medicines are already approved and being commercialized in the U.S. and international markets, either independently or through partnerships with larger pharmaceutical companies.
Pipeline
Donidalorsen is an ASO‑GalNAc conjugate that causes ribonuclease H1 (RNase H1)‑mediated degradation of PKK mRNA through binding to PKK mRNA, which results in reduced production of PKK protein.
Eplontersen is an antisense oligonucleotide-GalNAc conjugate that causes degradation of mutant and wild-type TTR mRNA through binding to the TTR mRNA, which results in a reduction of serum TTR protein and TTR protein deposits in tissues.
Olezarsen is an ASO-GalNAc 3 conjugate that binds to apoC-III mRNA leading to mRNA degradation and resulting in a reduction of serum apoC-III protein. Reduction of apoC-III protein leads to increased clearance of plasma TG and VLDL.
