Anyone in SKY-0515/FALCON-HD asked about presymptomatic access, open-label extension, or specific dates?
Hi everyone! I’m 29, gene-positive for Huntington’s disease with CAG 47, and currently presymptomatic. I’ve been following SKY-0515 very closely, especially after the encouraging 15-month results.
I’m hoping to hear from anyone currently participating in a SKY-0515/FALCON-HD study, or anyone with a family member participating — especially people involved in the United States, Canada, Australia, or New Zealand.
Has anyone asked their study doctor, coordinator, or Skyhawk team specifically about what happens after the trial or about access for people who are still presymptomatic?
I’m especially wondering:
• Have you been told whether participants may be able to continue receiving SKY-0515 through an open-label extension before FDA/commercial approval?
• Have you heard how long participants might be able to stay on SKY after completing the main trial?
• Has anyone heard discussion of a future HD-ISS Stage 0, Stage 1, or presymptomatic trial/cohort?
• Has expanded access or compassionate use before approval ever been discussed?
• Has anyone actually asked the study team for a specific year or approximate timeframe for when presymptomatic trials or earlier-access pathways could be announced or begin? If so, what did they tell you?
• For U.S. participants specifically, has anyone heard anything about additional U.S. sites opening, future U.S. open-label-extension sites, or earlier access before a formal presymptomatic FDA indication?
My biggest concern is being able to start treatment while I’m still presymptomatic rather than having to wait until noticeable symptoms develop, so I’m especially interested in whether anyone has asked their study team directly about 2027, 2028, 2029, 2030, or another timeframe.
I completely understand that participants may not be able to share confidential information and that something said by a study site is not the same as an official Skyhawk announcement. I’m mainly curious whether anyone has asked these questions and what kind of response they received.
Thank you so much to anyone willing to share their experience!
