March for Rare

Project Alive and the MPS Society are proud to co-host March for Rare in Washington, DC. Over two powerful days, families, advocates, and community leaders will meet with members of the U.S. House and Senate and engage with leaders at the FDA to advocate for meaningful progress in rare disease policy and treatment access. In light of the recent Complete Response Letter (CRL) for RGX-121, our community is coming together to ensure our collective voices are heard. Join us as we stand united for urgency, innovation, and a future with better outcomes for individuals living with Hunter syndrome and other rare diseases.

Project Alive and MPS Society are happy to be able to provide partial funding for families wanting to join our advocacy efforts. There will be a stipend per family has increased to $750 for up to two members of a household, and two nights stay. There will be a training provided before we go to the FDA and the Hill. Stipends available first come, first serve basis.

You must complete the form if you want to be booked at the hotel, have meetings scheduled on your behalf, and if you want meal stipends.

By contacting your U.S. Senators and Representatives, you’re putting a human face on Hunter syndrome and showing the urgent need for faster access to life-changing treatments like RGX-121 and DNL-310. Delays mean lost abilities, independence, and precious time for our children. Your voice can help lawmakers prioritize rare disease families, push for meaningful action, and make sure no child with Hunter syndrome is left behind.
