PPMD works to ensure that patient experience is central in product reviews. We convene families and other Duchenne advocacy organizations for regulatory events, including federal Advisory Committee meetings and summits, designed to inform regulators about the Duchenne patient experience.
Patient-Focused Drug Development
The FDA Safety & Innovation Act (FDASIA) and Prescription Drug User Fee Act V (PDUFA V) aligned perfectly with the dawning of a new day for our Duchenne community – one in which basic laboratory breakthroughs had developed into clinical trials, enabling the Duchenne pipeline of experimental therapies to become more robust than ever. We immediately embraced the opportunities presented to us through PDUFA V and have worked over the past few years to evolve the science of patient input and advance the field of Patient-Focused Drug Development.
Patient-Preferences Studies & Data Collection
PPMD conducted the first-ever scientifically rigorous survey of parents of Duchenne patients in 2012 to obtain quantitative evidence as to their views on benefit and risk. Results revealed a willingness of caregivers to accept considerable risk and uncertainty for a therapy that stops or even slows the progression of Duchenne. These findings have been useful in the therapeutic access based on community interest in accessing the first two approved drugs.
A second preference study on both caregiver and patients’ preferences for non-skeletal muscle benefits elicited the high value placed on cardiac and pulmonary benefits, including an acceptance for risk and uncertainty in order to achieve meaningful pulmonary outcomes such as a stronger cough and fewer lung infections. These findings provide insight into caregiver and patient priorities and preferences for treatments, and have value within both a regulatory and treatment access context.
In 2018, we are expanding our patient-preferences studies, including a global study of benefit-risk preferences and a study focused on risk tolerance in gene therapy interventions. Each of these studies represents collaborations with the patient, industry, academia, and federal agencies.
White Paper Publications
We have published a series of white papers analyzing PDUFA through the lens of the Duchenne community, including:
These publications highlight our Duchenne community’s policy priorities around the use of adaptive approval, limiting exposure to placebo, and the regulatory importance of a benefit-risk framework specific to each product. They also include narratives that speak to the urgency and unmet need within our patient community.
We convened the PPMD Duchenne Policy Forum in December of 2013, which included patients, providers, and researchers from around the world, as well as 18 representatives from the FDA. This meeting served as the foundation of the development of the PPMD-led guidance.
We led a comprehensive and multi-stakeholder effort to prepare the first ever patient initiated draft guidance to industry developing Duchenne therapies. This PPMD-led guidance, “Guidance for Industry Duchenne Muscular Dystrophy Developing Drugs for Treatment over the Spectrum of Disease” was submitted to FDA in June 2014. PPMD’s guidance – along with a Duchenne Community Policy Forum convened by PPMD in December of 2013 – was the foundation used by the agency to develop its own draft guidance on the same topic entitled, “Duchenne Muscular Dystrophy and Related Dystrophinopathies: Developing Drugs for Treatment”.
The FDA finalized the Duchenne guidance in January 2018. This was the first time a patient community took on drafting their own guidance, it created a model for other rare disease groups to follow.
Duchenne Patient-Focused Compass Meeting
In March of 2018, PPMD led the Duchenne Patient-Focused Compass Meeting. The meeting was a critical opportunity to bring the patient-community’s voice and experience back into the center of the on-going assessment of the Duchenne landscape. Over the last 18 months, PPMD conducted a series of systematic analyses of the Duchenne pipeline and recent community achievements, including a closer look examination of:
- The 2017 PPMD-led effort with our Duchenne Drug Development Roundtable (DDDR) partners to evaluate our research and regulatory learnings throughout 2015 and 2016.
- The January 2018 Lancet Neurology publication of the updated CDC Duchenne/Becker Care Considerations to reflect changing care standards in Duchenne and the emerging adult population.
- Recent Duchenne product approvals thrusting the community into a complex access environment.
Following engagement with key personnel at the FDA, we developed a meeting format that utilizes the FDA’s “Patient-Focused Drug Development Workshop” framework while also broadening the discussion scope to include stakeholders from other federal agencies, payers, the biopharmaceutical industry, and patient advocacy coalition partners. This expanded format allowed us to build upon our community’s work with the Duchenne guidance, patient preference studies, and formalized data collection.
“The Duchenne Patient-Focused Compass” meeting was comprised of panels of Duchenne community members (patients and caregivers) to explore ‘living with Duchenne’, clinical trial and therapeutic experiences, and access to approved therapies, across the Duchenne spectrum. In preparing for this meeting, PPMD invited all of our Duchenne community foundation partners to join the Community Advisory Board for this meeting and were proud to have 14 Duchenne foundations alongside us.
