Parent Project Muscular Dystrophy-led guidance seeks to address unmet clinical needs of individuals with Duchenne muscular dystrophy and accelerate development of safe and effective therapies
CHICAGO, June 25, 2014 /PRNewswire-USNewswire/ -- Parent Project Muscular Dystrophy (PPMD) and a broad coalition of stakeholders today submitted the first-ever patient advocacy-initiated draft guidance for a rare disease to the U.S. Food and Drug Administration (FDA) to help accelerate development and review of potential therapies for Duchenne muscular dystrophy (Duchenne).
"This landmark guidance represents a major milestone for the Duchenne community and may open the way for other rare disease groups to incorporate the patient perspective in a well-documented and quantifiable way, moving beyond any one family's experience," said PPMD President Pat Furlong. "By working closely with the FDA to provide industry and other clinical trial sponsors with clearer guidance from the patient perspective, we will increase the likelihood that clinical trials will be designed to better match the unique needs of Duchenne patients. It is our profound hope that this, in turn, will lead to the approval of much needed treatments for all people living with Duchenne muscular dystrophy."
Duchene, the most common lethal genetic disorder diagnosed in childhood, is a progressive and degenerative condition with no cure or disease-modifying treatments available in the United States.
Clinical trials for rare diseases like Duchenne are difficult to design and implement because of challenges such as small study populations, incomplete and evolving understanding of rare diseases, and effective ways to measure clinical impact of therapies being studied. Last year, FDA collaborated with PPMD and its scientific advisors to convene a policy forum that informed the process for developing the Duchenne community's suggested guidance.
"The U.S. Food and Drug Administration is appreciative of the input of Duchenne patients and patient advocates. Their input will enhance the essential data-driven process and evaluation of new therapies," said Janet Woodcock, M.D., Director of the Center for Drug Evaluation and Research at the U.S. Food and Drug Administration.
About The Suggested Guidance
More than 80 representatives of the Duchenne community - including parents and patients, medical experts, academics, and biopharmaceutical industry representatives - participated in seven working groups that met over the past six months to draft the guidance.
The cornerstone of the guidance encourages the FDA and trial sponsors to engage patients and their families at all stages of trial development and to take into account what they consider acceptable risk in clinical trials. A recent PPMD study published in the journal Clinical Therapeutics* shows that parents of children with Duchenne will accept substantial risk when balanced with noncurative slowing or stopping of the progression of muscle weakness, even with no improvement in life expectancy. The results came from the first-ever scientific survey of benefit/risk perspectives that PPMD conducted last year involving 120 Duchenne parents.
"As the FDA evaluates new drug applications for Duchenne therapies, it is imperative to take into consideration the value that parent decision makers place on even moderate benefits to function and mobility, and their tolerance for considerable risk and uncertainty," said Furlong. "Parents and caregivers of Duchenne children know firsthand that every day without treatment is another day closer to their child losing essential activities of daily living such as walking, feeding oneself, and eventually, breathing. When your child is living with Duchenne, you find yourself willing to take significant risk for even the hope of modest benefit. Parents can make these decisions thoughtfully and the FDA must recognize that. They cannot protect us from what we think is important in the drugs we need now."
Each section of the guidance includes extensive published or in-press peer-reviewed articles and focuses on six areas aimed at overcoming the challenges in trial design and implementation:
The suggested FDA guidance represents the culmination of PPMD's 20 year history of improving care and developing urgently needed therapies for Duchenne. PPMD led the effort to pass the MD-CARE Act, which created the Senator Paul Wellstone Muscular Dystrophy Cooperative Research Centers. The draft guidance builds on PPMD's effort to shape federal policy that reflects the needs of families living with Duchenne, including the release of "Putting Patients First" which calls on the FDA to act more flexibly when reviewing applications for Duchenne therapies. PPMD also ensured that the FDA Safety & Innovation Act of 2012 (FDASIA) responded to the needs of the community; recently published a groundbreaking benefit/risk study which documented the willingness of families to live with risk; and held a national PPMD-FDA Duchenne Policy Forum where the community made its needs and preferences in drug development known to the Agency.
About Duchenne muscular dystrophy
Duchenne, the most common form of childhood muscular dystrophy, is a progressive and fatal muscle disorder affecting boys and young men that causes the loss of muscle function, wheelchair dependency, and a decline in respiratory and cardiac function.
About Parent Project Muscular Dystrophy
Duchenne is a fatal genetic disorder that slowly robs young men of their muscle strength. Parent Project Muscular Dystrophy (PPMD) is the largest most comprehensive nonprofit organization in the United States focused on finding a cure for Duchenne muscular dystrophy. Our mission is to end Duchenne.
We invest deeply in treatments for this generation of young men affected by Duchenne and in research that will benefit future generations. We advocate in Washington, DC, and have secured hundreds of millions of dollars in funding. We demand optimal care, and we strengthen, unite, and educate the global Duchenne community.
Everything we do-and everything we have done since our founding in 1994-helps boys with Duchenne live longer, stronger lives. We will not rest until every young man has a treatment to end Duchenne. Go to www.ParentProjectMD.org for more information or to learn how you can support our efforts and help families affected by Duchenne.
