A MILESTONE DAY FOR THE RETT COMMUNITY
This is truly a historic day for the Rett syndrome community, the culmination of a journey that began more than a decade ago and succeeded only thanks to the perseverance and commitment of the families, researchers, and donors who were there every step of the way. We at IRSF are honored to have been a partner and advocate for families throughout this journey, identifying Trofinetide as applicable in Rett syndrome under then-CSO Dr. Steven Kaminsky in 2012, providing nearly $2 million in funding for the Phase 2 adult and pediatric trials, and facilitating study enrollment at our Center of Excellence network trial sites. Today, we celebrate with you and thank you for participating, donating, supporting, and raising your voice for Rett syndrome.
“We are grateful for the investments made by Acadia to bring this first approved treatment through Phase 3 and to FDA approval. We are grateful to all of our partners—doctors, researchers, scientists, our board of directors, and donors—who supported our vision to relentlessly pursue the development of trofinetide. But mostly, we celebrate and thank those courageous families who participated in the clinical trial process of trofinetide. It is because of their bravery that the Rett syndrome community is able to celebrate this milestone.”
– Melissa Kennedy, IRSF Chief Executive Officer
THIS IS JUST THE BEGINNING
Rett is not one-size-fits-all; because Rett syndrome has a broad range of presentations, we need a broad range of treatments and cures. No one treatment can benefit every single person with Rett, so we must continue to fund the most promising research. This is just the first of many treatments needed.
And there is so much reason for hope. Forty years ago, no one was investing in Rett syndrome research. Now that landscape has dramatically changed, positioning us for more breakthroughs like this. In 2023 alone, multiple gene therapy clinical trials will begin enrolling, 20+ companies are investing in treatments, and there are more than 40 active research projects accelerating our knowledge of what causes Rett syndrome.
With this momentum, we are positioned for more success and more ways to provide treatments that will make a profound difference in overcoming Rett and helping those with Rett reach their fullest potential. IRSF is with the community leading the fight, recently approving the largest research investment in our history–over $4.4M! –as part of our ongoing commitment to invest broadly and smartly in the most promising research at every stage.
OUR PROMISE TO YOU
We know you have many questions about DAYBUE, and we promise to be a resource of timely, updated information on when and how your child can access this treatment. While we will keep you informed, your doctor is the best resource to discuss DAYBUE’s benefit to your child and its addition to your treatment plan.
We promise to continue advocating at the federal and state level to ensure all families have affordable access to DAYBUE. This will be the first fight to access an FDA-approved treatment for Rett, but it won’t be the last.
With this announcement comes an opportunity to restate our commitment that we will press harder for more research, more trials, and more FDA-approved drugs to help in overcoming Rett. We promise to continue to relentlessly pursue treatments and curative approaches to create a world without Rett syndrome.
“We are thrilled that families now have a treatment option and the hope that their children may be able to do more and struggle less,” shared Kennedy. “Our mission of accelerating research continues until we can bring treatments including cures to ALL Rett syndrome patients, male and female, and with different presentations of this disease.”
