PM647 is designed to fix the genetic mutation that causes Alpha-1 Antitrypsin Deficiency, and Prime Medicine said the treatment could restore the normal protein and potentially help treat both the lung and liver problems caused by the disease.

REGENXBIO Inc. announced positive three-year long-term follow-up data from the Phase II ALTITUDE study of investigational surabgene lomparvovec, also known as sura-vec or ABBV-RGX-314, in non-proliferative diabetic retinopathy using suprachoroidal delivery, presented at the Retina Society 59th Annual Scientific Meeting in Los Angeles. In data as of August 17, 2026, 60% of all Dose Level 3 participants with three-year visits, or 6 of 10, achieved a greater than 2-step improvement on the Diabetic Retinopathy Severity Scale without additional treatment for diabetic retinopathy, and these participants experienced no vision-threatening events. Additionally, the majority of participants, 3 of 4, who achieved a 1-step DRSS improvement at one year without supplemental anti-VEGF injections went on to achieve a greater than 2-step DRSS improvement by three years without additional treatment. No new sura-vec-related safety signals and no intraocular inflammation were observed through three years in 17 participants receiving short-course prophylactic topical steroids. Dose Level 3 is being evaluated in the Phase IIb/III NAAVIGATE trial of sura-vec in NPDR, and REGENXBIO is developing sura-vec in collaboration with AbbVie.
