On April 25-26, 2013, the FDA is holding a workshop to discuss how best to facilitate and expedite the development of safe and effective drug therapies to treat signs and symptoms related to CFS and ME. This meeting is expected to attract not only patients and ME/CFS expert clinicians, but also other groups including pharmaceutical companies and the FDA. This is an unprecedented opportunity for us to get the attention and interest of the pharmaceutical industry and to bring a patient perspective to the development and review of drugs for ME/CFS.
Day 1 of the workshop will give patients the opportunity to share the symptoms and signs that they experience, their experience with treatments and how this disease affects their quality of life. This is being conducted as part of the Patient-Focused Drug Development Initiative, an FDA effort to incorporate the patient experience into the drug approval process by better understanding the patients’ perspective on the severity of their disease and the effectiveness of available treatments. ME/CFS has been chosen as one of the 20 diseases for which such a workshop will be conducted and will be the first of the 20 to go! For a disease like ME/CFS whose impact is poorly understood by those outside the community, this first day will provide the critical insights needed for discussions on the second day of the FDA workshop but just as importantly will also ensure that the drug approval process better incorporates the patient perspective going forward.
Day 2 of the workshop will include a scientific workshop on how to best facilitate and expedite the development of safe and effective drug therapies for the signs and symptoms related to ME/CFS. Presentations will include:
- Lessons learned from previous studies
- The role of drug repurposing
- Pathways to expediting drug therapies
- Appropriate clinical trial design in CFS and ME
- Outcome measures to assess efficacy
- Potential valid endpoint measurements of symptom improvement.
The Importance of both Symptoms and Biological Abnormalities
Obviously, it is critical that FDA and the pharmaceutical companies understand the symptoms you experience and the impact of those symptoms on your quality of life. But it is just as essential that they also understand the biological abnormalities that are associated with ME/CFS – biological abnormalities that are already being measured through lab tests and other testing. Some examples include:
- Neurological impairment seen in symptoms like sleep dysfunction, headaches and sensory disturbances and that can be measured in lab tests like SPECT scans or MRI.
- Cognitive dysfunction seen in symptoms like impaired memory and processing speed and that can be measured through various cognitive performance tests.
- Immunological dysfunction seen in cytokines abnormalities, high viral titers, RNASE-L abnormality and low natural killer cells.
- Autonomic dysfunction and orthostatic intolerance causes symptoms like dizziness, racing heart and feeling sick when stand for long periods and that can be measured by tests like tilt table tests, heart rate and blood pressure monitoring and blood volume.
- Post exertional malaise and low anaerobic threshold that cause a relapse after mental or physical exertion and documented by cardiopulmonary exercise testing.
By understanding both the symptoms and the related biological pathologies and associated abnormalities, pharmaceutical companies will be in a better position to identify opportunities to subgroup patients and potentially repurpose existing drugs that might treat ME/CFS. This is especially critical in a disease like ME/CFS which is too often described simply in terms of “fatigue not improved by rest”, is assumed to be due to depression, deconditioning or is thought to be simply another name for chronic fatigue.
To ensure that the pharmaceutical companies understand this biology, a group of ME/CFS organizations and advocates submitted a joint letter to the FDA to ask for assurance that a brief overview of the biology and abnormalities of ME/CFS will be summarized right at the beginning of the meeting. The letter that was sent can be found at https://dl.dropbox.com/u/89158245/LetterFDAWorkshopMar18.pdf
So what can you do to make sure the FDA and the pharmaceutical companies understand how ME/CFS has affected you and what you have experienced with treatments? There are a number of opportunities for you to participate and to provide comments.
- Register to attend the meeting and optionally provide comments
Here’s what you need to do:
- To attend in person, register first-come, first-serve at http://mecfsmeeting.eventbrite.com by April 8. You will be asked to provide your name and business, organization, or personal affiliation as applies (e.g., industry, government, patient). When you register, you will need to indicate that you wish to provide comments as outlined next.
- There are three opportunities to present comments at the meeting:
- You can request to be part of an initial panel discussion on the topics listed below.
If you wish to be considered to present comments part of initial panel discussions, you will need to indicate the topic that you wish to address when you register. Then, you will need to send a brief summary of your response to the topic(s) you selected to ME-CFS-Meeting@fda.hhs.gov. The deadline to send the summary of your comments is April 8. You will be notified before the meeting if you will be on a panel.
- You can participate in open moderated discussion following the panel discussions on the topics listed below.
You do not need to register to provide comments or have prepared testimony for this part of the discussion. A moderator will recognize participants to comment when they raise their hands.
- You can request to provide comments on other topics as part of the open comment period at the end of the day
If you want to do this, you will need to register as above. In addition, you will need to send a brief summary of your comments for the open public comment session to ME-CFS-Meeting@fda.hhs.gov. The deadline to submit the summary of your comments is April 8.
- Suggestions for those providing comments: For those who wish to provide comments, either as part of the panel or as part of the ‘open discussion’, the following information will be useful:
- The suggested topics include:
- Topic 1: Disease Symptoms and Daily Impacts That Matter Most to Patients
- Topic 2: Patients’ Perspectives on Current Approaches To Treating CFS and M
The questions that the FDA is asking on each of these topics are listed below. You are also given the option to suggest a topic when you register.
- In addition to the questions that the FDA asked, please provide comments about your lab/test abnormalities - linked to symptoms and dysfunction where possible – and indicate how those abnormalities changed as a result of treatment if known. Examples include:
- Abnormal VO2Max as a result of PENE/PEM
- Abnormal tilt test as indicative of orthostatic intolerance
- High inflammatory cytokines indicative of immunological issues
- Cognitive issues seen in impaired working memory and slow processing speed tested by cognitive performance testing
- Other suggestions:
- Comments should be concise and to the point. Avoid jargon. Speak about your personal experience and how this disease has affected you.
- For some people, the term biomarker may imply that the biomarker has been “validated”. It is better to use the term abnormalities or test abnormalities to avoid this confusion.
- Given that the time for comments may need to be shortened, it would be good for you to have both a 1-2 minute version and a 3-4 minute version.
- Provide comments by proxy: If you cannot attend but wish to provide comments, you can have a proxy provide them for you. You will need to register to do this.
- Participate in the FDA meeting remotely
- The meeting will also be webcast at http://mecfsmeeting.eventbrite.com. See http://www.fda.gov/Drugs/NewsEvents/ucm319188.htm for additional information about joining the meeting.
- Respond to two different surveys that are collecting information for the meeting.
- Both surveys are collecting information a) disease symptoms and daily impacts that matter most to patients and b) patient perspectives on current approaches to treating ME/CFS.
- Dr. Leonard Jason and his team and Dr. Lily Chu have created an online survey that uses checkboxes to collect information on symptoms, impact on daily life, treatments being used and the effect of treatments. For those who live outside the U.S., ignore questions about the U.S. region. The link to Dr. Jason’s and Dr. Chu’s survey is here.
- The CFIDS Association of America (CAA) has taken the questions from the FDA workshop agenda and turned them into an online questionnaire where you can type answers into text boxes. The link to the survey is here.
- Both surveys are open to everyone no matter where you live. Your responses will be anonymous and confidential.
- Please try to answer both questionnaires.
- Although the surveys may not ask for it specifically, don’t forget to also include comments as above about your lab abnormalities - linked to symptoms and disease dysfunction where possible – and indicate how those abnormalities changed as a result of treatment if known. Examples are given above in #1.
- Provide comments directly to the FDA now
- Go here and submit comments now by clicking on the ‘Comment Now!” box in the upper right corner of the page.
- You can also submit written comments to Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, Rockville, MD 20852. Include the docket number, which is “FDA-2012-N-0962-0004”.
- The Docket is open until August 2, 2013.
- The FDA is encouraging patients to provide answers to the questions asked in the Federal Register. But again, don’t forget to also include information about the biological abnormalities – linked to symptoms where possible – and indicate how those abnormalities changed as a result of treatment if known. Examples are given in above.
