This past month has been a painful reminder that progress is rarely a straight line. The Phase 3 trial of GTX-102 did not meet its primary or key secondary endpoints. For a community that has invested so much hope in therapies targeting the underlying biology of Angelman syndrome, that result was deeply disappointing. But a trial that doesn't deliver the result we hoped for still has something important to teach us. Understanding what happened, what the data can tell us and how we design and measure future trials will be part of the work ahead.For me, that is personal too. My own daughter is now an adult. Like so many parents, I have watched birthdays come and go while
wondering whether the breakthrough we hoped for would arrive in time to change her life. Sixteen years can feel like a lifetime when you are raising a child with a complex disease. And yet, in 2026, we are living through an extraordinary time in rare disease. Science is advancing at a pace I don’t think anyone could
have imagined when FAST Australia began. Artificial intelligence has the potential to find patterns in data we couldn’t previously see. Gene therapies and gene editing are no longer distant possibilities. Every year we understand more about Angelman syndrome, and every discovery creates another opportunity to improve lives.When FAST Australia began, therapies targeting the underlying cause of Angelman syndrome felt like something we hoped might happen one day. Today, those therapies have moved from the laboratory into clinical trials. Around the world, other rare genetic conditions are already being transformed through gene therapies and gene editing technologies. Diseases once thought untreatable are now being treated and, in some cases, children are effectively being cured. There is still enormous work to do before every person with Angelman syndrome can benefit from safe, effective and accessible treatments. But the conversation has changed. We now know enough to be testing therapies that target the underlying biology of Angelman syndrome in people. We don't yet know which approaches will ultimately deliver meaningful benefit, or what we willlearn along the way. Our job is to keep helping move that work forward.

Perhaps the greatest lesson of these sixteen years is that progress is built over years by people who keep showing up, through collaborations, friendships and a shared belief in what might be possible, even
when the finish line still feels a long way away.When I look at FAST Australia today, I am proud of what our community has built together. We fund nurses because care matters, build registries because data matters, advocate because systems matter and invest in research and clinical trial infrastructure because Australian families deserve
access to opportunities here at home.Sixteen years ago, we started with a dream of one daytreating Angelman syndrome. The mission has grown, but the dream has not changed.And I honestly believe the most exciting chapters are still to be written, together, by our community.Written by Meagan Cross | FAST Co-founder and CEO, but most importantly, Molly's mum
