EveryONE Medicines Names Michelle L. Mellion, MD, as New Chief Medical Officer
EveryONE Medicines, a trailblazing biotech company transforming the way individualized therapies are developed for children suffering from ultra-rare and life-threatening neurodegenerative diseases, has announced the appointment of Michelle L. Mellion, MD, as its new Chief Medical Officer. This appointment marks a significant milestone in the company’s evolution as it prepares to initiate its first-in-human clinical trials and build a global clinical infrastructure capable of supporting scalable, personalized therapeutic solutions.
Dr. Mellion joins the company at a pivotal time, bringing with her an extensive background in pediatric neurology, clinical development, and strategic leadership within the biopharmaceutical industry. In her new role, she will oversee the strategic design, execution, and expansion of EveryONE Medicines’ clinical development programs. Her leadership is expected to catalyze the launch of the company’s first clinical trial in the United Kingdom later this year, a program that aims to validate a novel model for individualized treatments targeting multiple genetically driven pediatric neurodegenerative disorders.
As Chief Medical Officer, Dr. Mellion will also be instrumental in developing and implementing the company’s global network of treatment centers. These centers will serve as critical infrastructure for delivering bespoke therapies to children who otherwise face limited or no treatment options. Her appointment signals EveryONE Medicines’ commitment not only to scientific innovation but also to the operational scalability of its platform—a challenge long faced by the field of individualized medicine.
A New Era in Individualized Therapy
Founded on the vision of creating a sustainable, globally scalable framework for individualized treatments, EveryONE Medicines is pushing the boundaries of traditional drug development. The company’s approach addresses a glaring gap in the treatment landscape: the absence of effective therapies for children suffering from ultra-rare genetic neurodegenerative disorders. These conditions often affect only a handful of patients globally, making conventional drug development models economically and logistically unfeasible.
Traditional pharmaceutical pipelines, shaped by commercial incentives and regulatory frameworks optimized for broader populations, often overlook these “n-of-1” diseases. EveryONE Medicines challenges this status quo by leveraging advances in genomics, bioinformatics, and regulatory science to enable a new pathway for individualized therapeutics. Their model centers on the development of Antisense Oligonucleotide (ASO) therapies tailored to each patient’s unique genetic mutation—a revolutionary shift toward truly personalized medicine.
Kent Rogers, CEO of EveryONE Medicines, emphasized the significance of Dr. Mellion’s arrival at this transformative juncture.
“Dr. Mellion is joining at a pivotal moment as we prepare to launch a first-of-its-kind clinical trial in the UK later this year, which is a critical step in demonstrating a new, scalable approach to treating ultra-rare pediatric neurodegenerative diseases,” said Rogers. “Current regulatory pathways are not designed for truly individualized medicines, and Michelle’s deep expertise in navigating these complexities will be invaluable as we work to advance a more proportional framework.”
Rogers further noted that Dr. Mellion’s leadership would be central to expanding EveryONE Medicines’ clinical presence into other geographies, including the European Union and the United States—regions where rare disease regulatory frameworks are evolving to accommodate the next generation of therapeutics.
Strategic Vision Meets Deep Clinical Expertise

Dr. Mellion’s unique blend of academic neurology, clinical practice, and industry leadership positions her as an ideal fit for the company’s ambitious mission. With over two decades of experience spanning neurology, rare disease drug development, and therapeutic innovation, she brings a holistic understanding of both patient care and the scientific rigors of translational medicine.
“EveryONE Medicines is redefining what’s possible for children with ultra-rare diseases by pioneering a sustainable approach to individualized medicine,” said Dr. Josh Ofman, chairman of the board at EveryONE Medicines. “Dr. Mellion’s expertise in neurology and her track record of industry leadership will be central to building the clinical infrastructure needed to efficiently develop, validate, and deliver these therapies at scale. Her guidance will not only accelerate our ability to bring life-changing medicines to more people living with ultra-rare diseases but also set the foundation for a future where no patient is left without options.”
Dr. Mellion echoed these sentiments, expressing her enthusiasm for contributing to a mission that aligns with both her professional expertise and personal passion.
“Throughout my career, I’ve witnessed the toll these diseases take on children and families and the limitations of a one-size-fits-all model,” said Mellion. “With ASO therapies and advancements in individualized development pathways, we already have the tools needed to address these complex conditions. I’m proud to join this team to create a new paradigm shaping a new era of individualized treatment grounded in precision, compassion, and clinical excellence.”
