RGNX Regenxbio
RGX-121 puts Regenxbio at the threshold of its first potential standalone approval, while the retina (AbbVie) and Duchenne programs build a second and third pillar for 2026–2027. The equity story is a classic “platform + royalty + binary PDUFA” mix, with a balance sheet extended into early 2027 via upfronts and royalty monetization.
