On behalf of our patient community, their families and caregivers, thank you for your commitment and support! The “Energy in Action” El-PFDD meeting for mitochondrial disease aimed to set the groundwork for creating effective therapies for mitochondrial disease. This was truly a milestone for our community. It also served as a testament to the power of individual patient advocacy groups to come together to benefit our disease community. The meeting was the culmination of more than a year of planning and collaboration by the patient advocacy groups facilitating this meeting. We are thankful for the leadership of our friends at MitoAction and the Muscular Dystrophy Association, who helped us pull this tremendous meeting together. We were grateful for the opportunity to amplify our collective voice for our distinguished guests from the U.S. Food and Drug Administration. Thank you for your time and support in bringing this meeting to fruition. Special thanks to Dr. Lucas Kempf, Acting Associate Director to the Rare Disease program in the Office of New Drugs, and Dr. Larissa Lapteva, Associate Director in the Division of Clinical Evaluation, Pharmacology, and Toxicology, Office of Tissues and Advanced Therapy, Center for Biologics Evaluation and Research, who provided great support and insightful commentary. Many thanks also to James Valentine, for his dedication to rare disease communities and his outstanding facilitation of our meeting. We are also grateful to Dr. Michio Hirano and Dr. Amy Goldstein for their excellent clinical presentations on mitochondrial disease and their enduring commitment to our community. Our patient families brought their voices to help us better understand their experiences, their struggles, and their hope. Courageous panelists put their energy in action and made a choice to share their perspective of certainty, amidst a path of often uncertainty. Our broader community came forward with a loud voice, through active participation in our meeting and our surveys. To our hundreds of participants, we are most grateful for your candor and your courage. Because of all of you, we have a renewed sense of optimism that may lead us towards new and innovative therapies and treatments, and a world without mitochondrial disease.
