Q: Who is the ideal patient for the Wilson gene therapy program? Would it be suited for patients well-controlled on copper chelators or zinc, or only for the most severe patients? A: Emil Kakkis, President, CEO, and Director, explained that about 20% of Wilson patients are not well-controlled or can't tolerate medications, making them the most addressable population. While some patients are stable, others not optimally managed could benefit from the treatment. The potential market remains large due to the size of the disease population.
Q: Regarding the interim analyses for the OI-AML study, if the study continues past the first interim, does it affect the likelihood of success? How would the timeline to commercialization vary? A: Emil Kakkis noted that whether the first interim hits or not doesn't impact the outcome, as it relates to how fast the lines separate. The commercialization timeline could be shortened if the first interim is successful, but the second interim would not significantly delay the BLA filing.
Q: What data should we focus on for the upcoming Angelman syndrome updates at medical conferences? A: Emil Kakkis mentioned that the focus will be on long-term data through day 338, showing the transformation of raw scores and GSV, and overall safety. This will help set up for the Phase III trial.
Q: When can we expect data from the additional stage one cohort for Wilson's disease, and what would you want to see to gain confidence in the regulatory and commercial outlook? A: Emil Kakkis stated that the study is expected to start early next year, with data taking most of the year to collect. They aim to see consistent reduction in standard care in the majority of patients, indicating a potent gene therapy.
Q: For UX111 for Sanfilippo syndrome, will heparan sulfate be the sole biomarker in the BLA, or will other measurements be included? A: Emil Kakkis confirmed that in addition to heparan sulfate, gangliosides, NSL data, and brain volume data will be included to support the efficacy chain leading to Bayley scores.
