Mission

Provide education and tools for people with rare disease.

990 for the year ended December 31, 2025

Program accomplishments

  • HEAT Kits: Disease-specific Hospital Emergency Advocacy and Treatment Kits (HEAT Kits) that put plain-language, expert-reviewed information directly into the hands of patients and healthcare. HEAT Kits enable patients to engage in the healthcare community with confidence, even when not feeling well. Distributed for five rare diseases across the country and sent via PDF internationally.
    Expenses $47,106
  • Livestream educational sessions bring people face to face with pharmacists, experts, and treatment developers to answer real questions about access, treatment decisions, and insurance. We avoid jargon, and encourage engagement with the presenter. Each session becomes enduring education on ERDC's YouTube platform, so the answers keep helping long after the livestream ends.Rare Candor Podcast: Unscripted conversations with real people, clinicians, and advocates about what it actually means to live with or care for someone with a rare disease. Available on Spotify and Apple, it's storytelling as advocacy, proof that the most powerful education comes from people telling the truth about their own lives.
    Expenses $24,191
  • ANCA Vasculitis Decision Tree: A step-by-step decision making and planning platform that walks people with GPA, MPA, or EPGA through a personalized path from diagnosis to emergency decision-making, backed by a formal white paper written for journal submission. It gives clinicians and patients alike a clear, print-ready guide built from the patterns our community has lived through again and again.
    Expenses $22,260
  • Public Policy: ERDC shows up where treatment access is actually decided with legislators and regulators, not just in the doctor's office. We've submitted formal comment letters, briefed congressional staff, and organized alongside national partners to oppose the withdrawal of essential medications and push back on pricing frameworks that leave 95% of rare diseases unprotected.
    Expenses $10,962
