These public comments are submitted to the docket number above in response to the Food and Drug Administration (FDA) notice of public meeting and request for comments dated September 14, 2012. These comments are endorsed by the undersigned and are offered respectfully for your consideration as you implement the FDA's patient-focused drug development initiative.
As stated in the public notice, the recent reauthorization of the Prescription Drug User Fee Act (PDUFA) includes performance goals and procedures that represent FDA’s commitments during FY 2013-2017, and Section X of these commitments relates to enhancing benefit-risk assessment in regulatory decision making. The public notice also makes clear that a key part of regulatory decision making is establishing the context in which the particular decision is made — a context that must include a thorough understanding of the severity of the treated condition and the adequacy of the existing treatment options.
We applaud the FDA's undertaking of these commitments and your prompt initiation of a process for obtaining patient perspectives on disease severity and unmet medical needs, including nomination of a preliminary set of disease areas that could benefit from a more systematic and expansive approach to obtaining such patient perspectives. We would also like to commend the FDA for acknowledging publicly that, "Though several programs exist to facilitate patient representation, there are currently few venues in which the patient perspective is discussed outside of a specific product's marketing application review." We wholeheartedly agree that it is terribly important that we work together to ensure that the patient perspective is taken fully into account at every regulatory stage of therapy development.
The FDA's notice invites public comments on the preliminary list of disease areas and requests that those who propose additional disease areas for consideration describe how they applied the criteria identified by the FDA. We would like, first, to offer an overarching suggestion we believe would enhance significantly the FDA's ability to accomplish the stated objectives of the patient-focused drug development initiative. Our suggestion is aimed directly and solely at the key targets the FDA has identified for the initiative.
Those key targets are made clear in the FDA's public notice — a thorough understanding of the severity of the treated condition and the unmet medical needs so as to set the context of regulatory decision making in regards to benefit and risk. If the FDA's key targets in this initiative were, instead, a more thorough understanding of such factors as the genetics or pathology of particular diseases, a list of 20 specific diseases might seem sensible. However, given the clearly stated key targets of the initiative, we feel strongly that a far more effective approach would be to identify "disease areas" that involve clusters of diseases that have profiles that are identical or very close to identical in terms of disease severity and unmet medical needs. This approach would enable FDA personnel, in a single meeting with patients and advocates representing a number of disorders, to develop a thorough understanding of severity and unmet medical needs held in common by all in this "disease area" and to set the context for benefit-risk evaluation and decision making for each of them.
We would like to illustrate the potential strength of this approach by suggesting one such "disease area" in which all the disorders listed have profiles that are identical or very close to identical in terms of disease severity and unmet medical needs and the patients and advocates of those disorders are in agreement that such is the case. We would also like to describe how this "disease area" meets all the criteria identified in the FDA public notice.
Illustrative Disease Area — Degenerative Neuromuscular Disorders Affecting Children
The disorders in this disease area would include: 1) the muscular dystrophies such as Duchenne muscular dystrophy, Becker muscular dystrophy, myotonic muscular dystrophy, congenital muscular dystrophy, Emery-Dreifuss muscular dystrophy, fascioscapulohumeral muscular dystrophy, and limb-girdle muscular dystrophy; 2) Friedreich ataxia; 3) ataxia telangiectasia; 4) spinal muscular atrophy; 5) Charcot-Marie-Tooth disease; 6) congenital myasthenia gravis; 7) congenital myopathies; and 8) severe pediatric onset forms of metabolic diseases of muscle such as mitochondrial myopathies.
This disease area and all the disorders listed within it clearly and fully meet all the criteria identified in the FDA's public notice and they meet those criteria in identical or very close to identical ways:
We believe that, in the disorders listed in this particular illustrative "disease area," the key factors of severity of disease and impact on quality of life as well as unmet medical needs are so close to identical that the stated objectives of the public meetings to be scheduled over the next five years could be accomplished for this whole set of disorders in a single meeting. Further, we believe that other "disease areas" could be readily defined so that, without adding to the number of meetings, the FDA's patient-focused drug development initiative could be extremely effective in setting the benefit-risk decision-making context for far more than 20 specific diseases.
We would welcome the opportunity to work closely with you on this approach. Again, we applaud and thank you for your active and energetic implementation of the commitments you have undertaken under the recently enacted Food and Drug Administration Safety and Innovation Act.
