Ultragenyx reports promising results in UX701 gene therapy study

Today, Ultragenyx Pharmaceutical Inc. (NASDAQ:RARE), a biopharmaceutical company, announced encouraging clinical activity and improvements in copper metabolism in the Phase 1/2/3 Cyprus2+ study of its investigational gene therapy, UX701, for the treatment of Wilson disease.

The study's first stage saw the enrollment of 15 patients across three dosing cohorts, with six patients successfully tapering off standard-of-care treatments as of the latest data cut-off in August. These patients demonstrated normalized levels of non-ceruloplasmin bound copper (NCC), indicating a stabilization of copper metabolism. Additionally, some patients showed increased ceruloplasmin-copper activity, suggesting enhanced ATP7b function, which is defective in Wilson disease.

Ultragenyx plans to add a fourth cohort to the ongoing study, which will receive a moderately higher dose of UX701 along with an optimized immunomodulation regimen, aiming to further improve the efficiency and efficacy of the treatment. The company's objective is to have the majority of patients discontinue standard-of-care treatment before advancing to the randomized, placebo-controlled second stage of the trial.

The Cyprus2+ study is designed in three stages, with the initial stage focusing on safety and efficacy to determine the optimal dose for the second stage. In this subsequent stage, patients will be randomized to receive either the selected dose of UX701 or a placebo. The primary safety and efficacy analyses will be conducted after 52 weeks, with long-term follow-up in the third stage.
