Response to FDA warning letter, proposal for FMT regulation, and some background of this project.

I wasn't planning on posting this yet, but the FDA letter has been publicly released and news organizations are already picking it up and contacting me about it, so I think it needs to be posted now. I may still make changes to it.
 
Format correct?
  1. Yes

A relevant quote (28:00) from Dr. Anthony Fauci on The Late Show with Stephen Colbert Season 9 Episode 107, 6/17/24 about AIDS patients' disagreements with him, the FDA, and clinical trials:


I see many people saying on social media, in news articles, etc., "Don't do DIY FMT". But I think a person would have to be completely incompetent and ignorant to not do DIY FMT if they were in our shoes.

Also, most of the people saying that will admit that the reason is "it's dangerous to use untested donors", which is either very ignorant or deceptive on their part. 1) Testing is extremely limited in value. 2) It's fairly easy to get the tests done.

And the people making those statements seem to be ignorant of the severe donor quality deficiencies at "official" sources of FMT.

He answered the same questions on PBS (Jun 18, 2024) https://www.pbs.org/newshour/show/i-had-that-dna-of-caring-for-people-fauci-discusses-new-book-and-life-in-public-health

Geoff Bennett:

When you describe that experience as enlightening, how did it inform your approach moving forward to confront other epidemics?

Dr. Anthony Fauci:

Yes, listen to the patients. Listen. And don't think that everything comes from the top down. Listen to the community. Listen to what they're experiencing. And you're going to make a much better and more appropriate response to whatever the disease challenge is. That was a lesson that was very well-learned from the activists.

I’ve suggested FMT to family members who are sicker than I am and their reasoning for not wanting to do it is because they think it doesn’t work despite me giving them a tremendous amount of evidence it does. When I tell them that it helped me, they say it was because of placebo lol.
 
"Right to Try":

https://www.kqed.org/stateofhealth/278362/will-californias-new-right-to-try-law-empower-or-exploit-patients
With the enactment of a new “Right to Try” law, California joins 31 other states that have already passed legislation to support patients’ efforts to access experimental drugs.

The FDA already offers a process, called “expanded access” or “compassionate use,” for some patients to obtain experimental drugs. But critics say it’s too slow and cumbersome, even though the FDA approves more than 99 percent of requests that come through that pipeline.

“It just takes so long, it’s inefficient, it’s ridiculous,” Calderon said of the FDA process. “I don’t understand.”
As the state laws proliferate, clinicians and medical ethicists are growing increasingly concerned about the potential safety and financial risks to patients.

“If we take the FDA out of it, how do we protect people from physicians or drug companies that will want to sell them things and will want to prey on their desperation?”

Dudley says the FDA and the clinical trial process were put in place for a reason.
Under the new law, all that patients and doctors can really do is ask for an experimental drug. Drug companies don’t have to give it to them, and insurance companies don’t have to pay for it.
Editor's note: The original version of this article incorrectly stated the California "Right To Try" law allowed access to an experimental drug at any stage. The law actually only allows a patient to request a drug that has passed through Phase I of the FDA clinical process, when a candidate drug is tested for toxicity on otherwise healthy subjects.
So this probably wouldn't work for FMT and the Human Microbes project.

https://righttotry.org/in-your-state/

Right To Try laws are already in place in 41 states and counting: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Maryland, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Washington, West Virginia, Wisconsin, and Wyoming. Eleven additional states have introduced the law.

Edit:

There's a federal one too, established in 2018. But it requires you to have a life-threatening condition. https://www.fda.gov/patients/learn-about-expanded-access-and-other-treatment-options/right-try

The Right to Try Act is one way for patients who have been diagnosed with life-threatening diseases or conditions who have tried all approved treatment options and who are unable to participate in a clinical trial to access certain investigational treatment options. FDA’s role in implementing the Right to Try Act is limited to receiving and posting certain information submitted to the agency.

I finally got a response from the FDA about what the requirements would be.

Here's what I wrote to them:
My understanding is that it's not possible for me/Human Microbes to operate under an IND in the way I am currently operating, but I want to confirm and check the exact details/requirements.

My goal: Find stool donors for FMT (fecal microbiota transplants) who are safe and effective. Make these stool donors available to anyone who needs a stool donor for FMT, including clinical trials, doctors, and patients if possible. I'm not targeting C. diff, and I'm not interested in providing stool only for C. diff. I'm targeting all forms of chronic disease.

Problem: High-quality donors are extremely rare. I've screened over a million applicants and still haven't found one that meets the ideal criteria. This is one reason we do not operate a laboratory since that would limit our potential donor pool to a handful of local donors. We recruit donors from all over the US and around the world, and they ship their stool directly to recipients.

Human Microbes is the middleman, finding, screening, and ranking the donors, taking payments, and passing on orders to the donors who are trained to collect the stool and ship it out.

I've seen quotes of an IND costing millions of dollars, but I don't necessarily want to get a drug approved to market.

I understand that I would need a separate IND for every condition that I provide stool for. So dozens of INDs would be required for "chronic disease".

Additionally, my understanding is that we would need a laboratory where we manufacture "a drug" according to GMP standards. So having donors around the US may not be viable, especially if they're shipping directly to recipients.

Additionally, my understanding is that it may not be viable due to the fact that I have to offer $1 million per stool to the donor (<link to rough draft of new blog>) in order to get a donor that meets the ideal criteria, which means I have to have a buyer to sell their stool to for more than $1 million.

And currently, since I have no funding, all the money comes from selling donor's stool directly to recipients.

I don't want to waste time and money on something that isn't viable under the current regulatory framework. And if someone offers funding, I'd like to know exactly what is and isn't possible in the case that I did have funding.

Their response:
1. Do I need a centralized manufacturing facility?

You must comply with current good manufacturing (cGMP) requirements (see 21 CFR parts 210 and 211). In order to do so you need to have one or more manufacturing facilities where your product(s) are produced under cGMP conditions. This is true even if you are manufacturing drugs to be studied under IND. This could be a Contract Manufacturing facility that you pay to perform the manufacturing for you rather than doing it yourself. Additionally, you would need to work with a clinical laboratory to ensure proper testing of the donated stool and the individual donors for pathogens of concern.

2. Can I have a network of donors around the country?

For safety reasons, we have not permitted investigators to use off-site donations. However, you may propose a plan to ensure chain of custody of the stool donated off-site in your IND submission and we will review the adequacy of your safety assessments to determine if this would be permitted. Collection of stool from donors around the country may also be possible by setting up multiple collection sites run by your company for this purpose.

3. Do I need multiple INDs for multiple indications?

Yes, you will need an IND for each indication. However, you may submit an IND that will contain all your product information, and then cross-reference that IND for your other submissions.

4. Charging for the product.

You may submit a request for cost recovery along with your IND submission. Cost recovery under this mechanism is limited to recovery of costs associated with the manufacturing of the product only.

5. What does it cost to submit an IND to FDA?

There is no cost associated with submission of an IND application to the agency.

6. Do I need licensed medical personnel involved in providing my investigational product to people?

Yes, regardless of the indication you are targeting, you must have licensed medical professionals overseeing the study procedures, including, but not limited to, administration of the study drugs, monitoring of patients, and assessment of adverse events.

7. Is what I am doing consistent with IND requirements? I don't want to waste time and money on something that isn't viable under the current regulatory framework.

Your current model is not consistent with the IND requirements for assessment of investigational drugs or biological products. To ensure the safety of subjects, all INDs must have appropriate licensed medical personnel and be in compliance with all regulatory requirements. Please see the guidance, for more information on submission of IND applications. While submission of an IND has no cost, complying with the regulatory requirements might require additional infrastructure on your end.

My thoughts:

1. The lab requirement is totally inappropriate. It would increase costs massively without making FMT any safer. It makes this project completely non-viable without significant funding.

This is how our donors currently do it. Our donors are essentially making and preparing a human-fermented food. Preparing and shipping it as you would with any other homemade food, should be entirely adequate. Having them visit a local lab to poop, or having them drop off their poop there for someone at the lab to turn into capsules/enemas is completely unnecessary.

Yes, contamination needs to be considered and avoided, but this is poop we're talking about, not some sterile drug.

The testing requirements are vague. For example, would each stool need to be tested? If not, what is the frequency of testing that would be required for donors and their stools?


2. This sounds vague, and it sounds like they may allow donors to ship us their stool. If so, there's no difference from them shipping their stool directly to recipients. A collection site would be similar to the lab -- does absolutely nothing to improve safety.


4. So it doesn't cover the costs required to recruit and pay donors? That makes this project completely non-viable without major funding.


5. I guess the "millions of dollars for an IND" articles are referring to the entire process of developing a drug and running clinical trials?


6. This sounds a bit vague. It sounds like one remote physician (anywhere in the US) may be able to be hired to "oversee the study procedures", and then patients could visit their own physicians around the US for "administration of the study drugs, monitoring of patients, and assessment of adverse events".


Overall, it seems like it would require HM to be turned into a stool bank rather than a source of stool donors. It does sound like, with the appropriate funding, HM could get a "drug/biologic" officially approved.

I will follow up with them for clarification.

How FMT is regulated in other countries:​


FMT in Europe:​


The use of Faecal Microbiota Transplantation (FMT) in Europe: A Europe-wide survey (2021) https://www.thelancet.com/journals/lanepe/article/PIIS2666-7762(21)00158-7/fulltext - the UK has the highest rate of non-CDI use.
Regulation varied across countries and centres. Formal regulation was in place at 12/31 (39%) centres; of whom 7/31 (23%) were regulated by the national medicines’ authorities, 4/31 (13%) were regulated by the national tissue authorities, and 1/31 (3%) were regulated locally by the hospital administration. Informal regulation where the centres were in dialogue with the national health authorities were present at 9/31 (29%) centres, and 3/31 (10%) centres reported having ethics approval only. Seven (23%) centres reported having no regulation.

Regulation, risk and safety of Faecal Microbiota Transplant (2020) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7280140/ - by UK authors. Table 1 has a list of countries and how they regulate FMT.
In the EU, a medicinal product can only be placed on the market if quality, efficacy and safety standards are met and a marketing authorisation has been issued. Currently there are no MHRA (UK agency) marketing authorisations for FMT products, thus material used for FMT is considered to be unlicensed in the UK.

Unlicensed medicinal products are often used in clinical practice; this is permitted by a derogation in the Medicines Directive (Article 5.1 of Directive 2001/83/EC relating to medicinal products for human use (Medicinal Products Directive). This allows member states to develop national provisions to allow supply of unlicensed products to meet the “special needs” of certain patients providing the supply is unsolicited.

One could argue that FMT has similarities with probiotics which are generally considered foods or dietary supplements rather than drugs and thus have minimal regulatory requirements. It is the lack of characterisation of microbial strains that precludes the classification of FMT as a probiotic according to expert consensus.

FMT in the UK:​


The growth of faecal microbiota transplantation in the UK: time for a registry? (2022) https://www.thelancet.com/journals/langas/article/PIIS2468-1253(21)00436-2/abstract - paywalled.

Regulation of faecal microbiota transplant (Human Tissue Authority) https://www.hta.gov.uk/guidance-professionals/regulated-sectors/human-application/regulation-faecal-microbiota-transplant

"FMT is outside the scope of the Human Tissue (Quality and Safety for Human Application) Regulations, 2007 (as amended) and is not regulated by the HTA. Establishments seeking to perform FMT should contact the MHRA Medicines Borderline Section for further advice."

On behalf of the UK Licensing Authority, the Medicines and Healthcare products Regulatory Agency (MHRA) regulates medicinal products for human use in accordance with the European Community’s medicinal products directive.

If a classifier does decide that a product is a medicinal product, then unless an exemption applies, it will be subject to the Human Medicines Regulations 2012 [SI 2012/1916] (“the Regulations”).

The MHRA view is that claims to “maintain” or “help to maintain” “dietary maintenance” or “support” health or a healthy lifestyle, can be approved under food law, and would not normally regard such claims to be medicinal.

(ii) Obtaining a licence to supply a licensed medicine https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/872742/GN8_FINAL_10_03_2020__combined_.pdf - FMT and marketing authorization are covered on the last two pages.

The MHRA is aware of the recent guidance issued by the National Institute for Health and Care Excellence (NICE) in March 2014, regarding the use of FMT to treat for recurrent Clostridium difficile infection.

MHRA is of the view that FMT falls within the definition of a medicinal product.

Products that are not industrially prepared are not subject to the requirements of the Medicines Directive.

The Medicines Directive shall not apply to medicinal products intended for research and development trials, but without prejudice to the provisions of Directive 2001/20/EC regarding clinical trials on medicinal products for human use (further to Article 3).



FMT in Australia:​


Faecal microbiota transplantation in Australia: bogged down in regulatory uncertainty (Feb 2019): https://onlinelibrary.wiley.com/doi/full/10.1111/imj.14212
FMT is not neatly classifiable under the current regulatory Therapeutic Goods Association (TGA) definitions of a drug, tissue or organ. At present, there is both under- and over-regulation of FMT in Australia. On one hand, FMT may be delivered in the local care setting without being subject to agreed standards for screening and manufacturing practice. Medical practitioners are able to compound and administer a therapeutic product to a patient under their care with appropriate consent. On the other hand, supply of FMT aliquots from stool banks that adhere to rigorous standards is not currently permissible. Current legislation prohibits the wider distribution of therapeutic products that are not certified according to Good Manufacturing Practice (GMP) protocols.

The need for GMP certification, as currently interpreted, represents a significant barrier to the establishment of a National Stool Bank. Beyond stringent screening for potentially transmissible conditions, a GMP requirement for standardisation of donor faecal product is not achievable. Moreover, the costs of setting up and maintaining a GMP-licensed stool bank facility are prohibitive.


Faecal microbiota transplant products regulation (2023) https://www.tga.gov.au/products/biologicals-blood-and-tissues-and-advanced-therapies/biologicals/faecal-microbiota-transplant-products-regulation
How your FMT product will be regulated by TGA depends on the level of clinical oversight and external governance in its preparation.

"Minimally manipulated" FMT is Class 2, and subject to GMP licensing. https://www.tga.gov.au/resources/resource/guidance/faecal-microbiota-transplant-fmt-product-regulation


Donor screening requirements https://www.legislation.gov.au/F2020L01011/latest/text

Highly overreliant on testing. Blood & stool testing every 90 days. A stool sample must be taken from each stool; must be stored at or below minus 70°C.


Faecal Microbiota Transplant (FMT) - Outcomes from the FMT Stakeholder Forum (Sep 2019) https://www.tga.gov.au/resources/publication/publications/faecal-microbiota-transplant-fmt-outcomes-fmt-stakeholder-forum


Contact TGA https://www.tga.gov.au/get-in-touch

They use https://consultations.tga.gov.au/ to take feedback prior to changing regulations. The last round was in 2019-2020. There are some interesting ones that disagree with the current regulations:


Submissions received: Options for the regulation of Faecal Microbiota Transplantation materials (Sep 2019) https://www.tga.gov.au/resources/publication/publications/submissions-received-options-regulation-faecal-microbiota-transplantation-materials

Biomebank says "Regulatory focus on safety not standardisation of product".

CDD says "It is well known that the FDA rule of initially using antibiotics for C. diff is not evidence-based."
"There are no drugs nor biologics tested for decades before marketing."
"FMT does not meet the current definition of a biological"
Makes some arguments against GMP, at least for hospitals.

FMT Consensus Group says Australia is one of the leaders in this field.
FMT is not a drug. FMT has been conducted at home by consenting adults for many years. Over-regulation would not change this or might increase home-FMT.

Given the complexity of FMT, we formed a multidisciplinary steering committee that I chair that aims to
discuss and recommend donor selection and screening, indications, development of FMT centres and
future research. Members include Dr Sudarshan Paramsothy, Dr David Andresen, Dr Viraj Kariyawasam and Dr Craig Haifer. We have decided on a working timetable, criteria for panel nominees, and proceeded to nominate panel members. We have sought endorsement from the Gastroenterological Society of Australia,
Australian Society of Infectious Diseases and The Royal College of Pathologists of Australia and have
representatives from each of these organisations. Panel nominees include gastroenterologists, infectious diseases specialists and pathologists from across Australia and overseas. We have invited the TGA to
participate and will involve a consumer/ patient representative.

Fiona Stanley Hospital says we do not think it logical for FMT to be considered a biological, or regulated as such.

St Vincent's Hospital, Department of Gastroenterology:
We recognise that FMT involves the transfer of human cells from donor to recipient, and therefore requires stringent donor screening for infections and medical co-morbidities. However, regulation of FMT as a Class 2 biologic or higher under the current biologic regulatory framework would impose Good Manufacturing Practice (GMP) requirements, and would be excessively onerous.

In contrast to the biologic and pharmaceutical agents regulated under GMP, there is no logical requirement for FMT to be produced in a sterile environment as faecal matter is not sterile.

There are further risks of imposing GMP approved FMT processing facilities, for the preparation of FMT: [lists financial and regulatory burdens, and DIY without supervision]

Furthermore, consideration should be given as to how a national registry could be developed to facilitate tracking donor and recipient health long term.

Many of the positions of these groups align quite well with what I've suggested, and with what Human Microbes already does. I think the majority of the groups above would agree with allowing access to our donors, as is, if they knew we existed and read the recent blog posts.


Submissions received: Draft standards for faecal microbiota transplant (FMT) products (Aug 2020) https://www.tga.gov.au/submissions-received-draft-standards-faecal-microbiota-transplant-fmt-products

Anon 2 says: As researchers, infectious diseases physicians and microbiologists we have concerns that the TGA’s plans to regulate some FMT products as Class 2 biologicals and impose the requirement that all screening tests used on donors be validated for screening purposes will ultimately result in reducing the safety and availability of FMT in Australia.

Biomebank says We have already spent $710,000 during 2019 with the aim of equipping our laboratory to meet the GMP standard. This does cost does not include TGA fees for GMP inspection or dossier assessment. We believe that the costs of TGA assessment and producing a dossier for a biological agent are too high. The regulatory costs will increase the price of FMT product to the point where it may limit access to the therapy.

Fiona Stanley Hospital and the FMT consensus group challenge the class IV IVD test validation standards.

Gastroenterological Society of Australia (GESA) argues that over-regulation of FMT severely limits availability/affordability and makes patients resort to unsupervised DIY at home. They argue against GMP standards.

The Microbiology Histopath Diagnostic Specialists one is interesting and has many disagreements, such as: freezing stool to test it later. Norovirus and Rotavirus. H.pylori.

Page 24: In Finland, Fimea, the national competent authority for regulating pharmaceuticals and blood and tissue products, has stated that stool is not a drug, and FMT does not fall under their regulation. Therefore, FMT does not have specific regulations in Finland thus far and is therefore governed by the existing rules and regulations affecting health care.
