Stem Cell Person of the Year 2016: Patient Advocate Ted Harada

Stem cell ethics meeting

Ted, Me, and Judy

Patient advocate Ted Harada is the recipient of this year’s Stem Cell Person of the Year Award.

Congrats also to the runner-up, HD patient advocate Judy Roberson. The three of us together are pictured at left.

You can read about the 20 nominees here and see the vote results that picked the 10 finalists here.

Very sadly, as many of you know, Ted passed away just a few months ago from a brain tumor so I am giving him this award posthumously. Accepting the award on his behalf is his wife Michelle.  Ted and I shared a deep commitment to our families. You can see a picture of Ted, Michelle, and their kids below. What a great family!

You can see a video of Ted talking about Right To Try below.

Each year that I’ve done the Stem Cell Person of the Year Award, I’ve been faced with the wonderful, but difficult challenge of picking one winner out of a group of outstanding finalists and this year was no different.

With this award that includes a $2,000 prize, I’m looking for an outside-the-box risk taker who has made a positive impact in the world of stem cells. Ted fit the bill perfectly. Ted Harada Family

Ted was a clinical trial participant for a new stem cell therapy for ALS in a trial run by the biotech Neuralstem. As such, Ted put himself at risk (transplanted cells have risks, immunosuppression has risks, etc.). He did this for the benefit of the field and for other patients. However, Ted went well beyond that. He was also a tireless patient advocate and educator who inspired countless people.

Ted respected other’s opinions and was a true class act. For instance, although Ted and I didn’t see entirely eye-to-eye on some things like Right to Try, that wasn’t a wedge. He served as a bridge between different parts of the community. Here at UC Davis we run an annual symposium on stem cell ethics and one year Ted was an invited speaker. He made a big, positive impact at our meeting.

Overall, Ted left the world including the stem cell and regenerative medicine arena a far better place. You can read my tribute to Ted after his death here. I only wish I could have given him this award in person.

Meeting review of unique stem cell ethics symposium @UCDAVIS

On Thursday here at UC Davis School of Medicine we held our second annual Stem Cell Ethics Symposium. The symposium was organized by Drs. Mark Yarborough and Nanette Joyce as well as me.

In this post I report on key take homes from the meeting and summarize the specific talks.

As far as I know, this is one of the few events in the world where there is such a wide diversity of stakeholders present both as speakers and in the audience to specifically discuss stem cell ethics for a full day. The participants included numerous patients and patient advocates, bioethicists, stem cell researchers, physicians, attorneys, institutional compliance officers, and more.

Stem cell ethics meeting

One of the things that I most appreciated about this meeting is that diverse views were welcomed and we dealt head on with some of the most challenging ethical issues related to stem cells.

I also got to meet in person some people I had only previously known on-line including keynote speaker Tim Caulfied, patient advocate Ted Harada, and advocate and frequent commenter on this blog, Cathy Danielson, which was fantastic. My colleague Leigh Turner was also present. Old friend and Huntington’s Disease advocate, Judy Roberson, was there as well. You can see the picture above of Ted, Judy, and me.

After a great introduction by our new Dean of the School of Medicine, Dr. Julie Freischlag, Nanette Joyce started things off with a very powerful talk about her experiences with her ALS patients. Her patients are facing incredibly intense challenges as they deal with all that ALS brings. Both in her medical specialty and amongst her patients, she noted, there is growing interest in stem cell treatments. Dr. Joyce expressed her concern over the lack of evidence of safety and efficacy, and how elements of hype have entered into the arena of ALS and stem cells. ALS is a very heterogeneous disease with ups and downs as well in individual patients, but life expectancy on average is very short after diagnosis.

One of Dr. Joyce’s patients, Michael, then gave a talk about his experiences with ALS. I found it really striking. Literally every day he goes on-line and checks out resources to search for opportunities for ALS patients such as clinical trials. Michael indicated that as far as he knows he’s not eligible for any trials so far. This was a theme that several people mentioned during the day: just because there are trials out there does not mean that patients with ALS or other conditions can be part of them. Patients are seeking other opportunities.

Next up was Ted Harada, who spoke passionately about his experiences with ALS, the ups and the downs, what is really like to get a stem cell treatment and be in a clinical trial. His talked about his willingness to take risks. He said he’d literally rather die trying something than not try to do something about his ALS. Ted has had two rounds of treatment for ALS as part of the Neuralstem clinical trial and he reported that it has really helped him. One of Ted’s concerns is that he may not be eligible to get a future third treatment from Neuralstem for various technical rules of the clinical trial, which is one reason he is such a strong advocate for Right To Try laws. However, Ted said he feels that most likely few or no patients will be directly treated as a result of Right to Try, but rather that it will open up a dialogue and create other positive outcomes that lead to more patient opportunities.

From both Michael’s and Ted’s talks, i also learned that it can take a very long time (potentially a few years) to definitively diagnosis ALS. Patients facing ALS are likely to have a much higher level of risk tolerance than others might imagine. Understandably they have a strong drive to take action.

I spoke next and focused on the growing challenge that the FDA and the stem cell field face of chains of stem cell clinics that appear to be selling unapproved stem cell drugs without FDA licensing. I talked a bit about the growth in providers offering unapproved stem cell “treatments” at Cell Surgical Network as an example. More broadly, the clinics argue that what they do is beyond the scope of the FDA’s regulatory authority. I discussed new FDA guidances that bear on this issue and which would seem to directly contradict the views of many of the clinics, squarely placing them and their products in the FDA sphere from my perspective. The clinics of course disagree. I also emphasized how the FDA currently is asking for comments on these guidances for the next couple weeks.Tim Caulfield

Tim Caulfield spoke next, giving a wonderful talk. In the stem cell world, hype is not just limited to dubious stem cell clinics. Tim focused on hype in the stem cell field and in particular hype involving scientific publications. He even talked about hype about hype. In the current environment there are strong pressures for scientists to hype their work, including in particular in abstracts. What is the relationship between hype in science articles and in the media? He discussed how widespread pressure to commercialize biomedical research including stem cell efforts sometimes has negative consequences and can contribute to hype.

Alison SorkinAlison Sorkin, Deputy General Counsel for University of Colorado Health, talked about Right To Try from her experiences in the trenches. With the passage of the Right To Try Law in Colorado, Sorkin was there for the intense repercussions. The next working day after the law was passed, patients starting contacting the University of Colorado seeking treatment specifically under the law. Sorkin talked about strict the Colorado law actually is, making it very limited in scope in reality. She also discussed problematic issues with the specifics of the law such as that patients would be responsible for paying for all of their own healthcare for 6 months after treatment under Right To Try as insurers would be exempt from having to provide ANY coverage. There seems to be a growing sense that Right To Try in Colorado may not actually lead to any patients getting non-FDA approved drugs. However, the FDA is paying close attention to Right To Try and one potential consequence of the various Right To Try laws passed in states is that the FDA could be influenced in terms of policies on expanded access (compassionate use).Leigh Turner

Leigh Turner gave a very timely, excellent talk on the FDA, stem cell clinics that do not have FDA licensing or approval, and the potential consequences of this current dynamic. Leigh went into helpful detail on the clinic claims, the types of stem cells they use, and how these relate to the new FDA guidances. He discussed Cell Surgical Network and Stemgenex. It is notable that Leigh gave specific examples and names clinics by name, which I agree is vital to the discussion of the regulatory sphere and the place of stem cell clinics.

Gerhard Bauer, my colleague here at UC Davis and one of my favorite stem cell scientists, gave a wonderful talk on his experiences and perspectives over the decades as a pioneering stem cell and gene therapy clinical researcher as well as earlier as a regulator at the FDA of Austria. Gerhard’s discussion ranged from his experiences in these roles to also his own person experiences as someone who has dealt with doctors and also lost many friends to disease including HIV. I also appreciate how he provided his views from his real world experiences wending his own clinical trials through the processes and how much work it takes just to get an IND. How great it feels to get to that point!

A few additional notes

Mary Ann Chirba, a voice for increased patient autonomy in terms of their cells, was going to be a speaker, but got snowed in at Boston. Richard Garr, Neuralstem CEO, was also scheduled originally to speak, but couldn’t make it. They were missed, but still we had a diverse, dynamic group of perhaps 70-80 attendees.

A big thanks to Julie Bechtel who helped to arrange the event.

New Interview with FDA on Key Stem Cell Regulatory Issues & Its Own Research

FDAIt’s been a seemingly rather quiet year on the regulatory front in the US when it comes to direct-to-consumer stem cell interventions even as the number of dubious stem cell clinics continues to skyrocket.

I requested an interview with the FDA to cover the key pressing issues in this arena. I want to thank the FDA for taking the time to do this interview.

Below are their answers covering regulation of SVF, homologous use, FDA action/inaction on dubious stem cell clinics, Right To Try Laws, and the FDA’s own research on stem cells.

Paul: One of the hot topics in the stem cell arena is the production and use of stem cells from adipose tissue with the most common product being called stromal vascular fraction (SVF). A current debate is whether CBER views SVF as a biological drug product. Could you please comment on SVF and whether it is a 351 or 361 product? is it more than minimally manipulated? If such a definition/guidance is on a case-by-case basis, can you cite any examples of where SVF has been defined simply as 361? The field could really benefit from some clarity on this issue.

FDA:  FDA recognizes the importance of this issue and the necessity for clear communication regarding minimal-manipulation, SVF, and other stem cell-based products.  It is understandable that the field is eager for clarification on the categorization of SVF and other stem cell-based products and FDA develops guidance on these topics as the specific regulatory approaches are sufficiently mature.

The Agency recently issued or is actively engaged in developing draft guidance on these topics:

CBER’s 2014 Guidance Agenda is available here:

http://www.fda.gov/downloads/biologicsbloodvaccines/guidancecomplianceregulatoryinformation/guidances/ucm338498.pdf

Paul: Another area where some additional clarity would be helpful is on non-homologous use. Is it correct to say that even if a biological product is defined as not more than minimally manipulated but it is used in a non-homologous manner (e.g. adipose used for a neurological disorder) does that product still require approval as a 351?

FDA:  In order to be regulated solely under section 361 of the PHS Act, a HCT/P must meet all of the criteria in CFR 1271.10(a), including the requirement for homologous use.

CFR 1271.10 can be accessed here: http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/cfrsearch.cfm?fr=1271.10.

Paul: A number of stem cell researchers have noted a lack of apparent FDA/CBER action in 2014 with regards to stem cell clinics selling interventions based on SVF or other unapproved stem cell products and/or apparent non-homologous use coupled to broad claims by clinics (e.g. “our stem cell treatments can treat 20 different conditions”), etc. Without commenting on specific cases of course, could you comment on why the FDA/CBER appear to be relatively less active in regulating stem cell clinics in 2014? For example, in 2012-2013 there were numerous Warning Letters issued, but none in 2014 related to stem cells to my knowledge. It certainly seems that the problem of stem cell clinics is not going away so that’s not the explanation so less FDA action. If anything there are dramatically more of such clinics in the US now than in past years. Why is CBER not taking action?

FDA:  As discussed above, CBER is actively working to develop guidance on the issues relating to SVF and other unapproved stem cell-based products. These guidances will offer necessary clarification with regard to HCT/P regulations.

As you know, FDA cannot comment on any potential actions or open investigations.

Paul: Right To Try (RTT) laws have been passed in several states and the current trend seems to be for more states to pass such laws. What is CBER’s view of RTT? How do these state laws interface with the federal laws that authorize the FDA to regulate investigational drugs?

FDA:  State laws, such as the Right to Try laws, do not supersede federal laws. Please keep in mind that through FDA Expanded Access or “compassionate use”, investigational products often can be made available for a patient with a serious or immediately life-threatening disease who does not respond to current approved treatments for a variety of reasons.

Additionally, Right to Try Laws share similar aspects to the use of an investigational product under FDA’s expanded access. In both cases, a treating physician must recommend the experimental product and be able and willing to use it to treat the patient.  Additionally, the drug manufacturer must be willing to provide the experimental product. States cannot force drug manufacturers to provide their products, nor can they force physicians to recommend an experimental product or use such a product to treat a patient.

Paul: Many members of the stem cell community find it notable that CBER conducts its own stem cell research including on MSCs. Could you please tell us more about this research program and its goals? What has it achieved so far and what do you foresee for its future?

FDA:  The MSC Consortium, which started work in mid-2010, was established to facilitate the development of products and therapies that utilize mesenchymal stem cells (MSCs). Through research, the  Consortium aims to answer the complex scientific questions that face the development of stem cell-based products. The research of the Consortium is meant to contribute to the understanding of the underlying science regarding MSCs and the goal is that increasing understanding of MSCs will facilitate development of safe and effective MSC-based products.

The Consortium is studying eight unique cell lines from eight distinct adult donors, who donated stem cells from their bone marrow.  The cells were purchased from commercial sources.

The type of cell into which MSCs will differentiate depends on the conditions under which they are grown.  Similarly, factors such as the age or gender of the MSC donor may affect the quality and performance of these cells. The Consortium’s research is looking at how the biological functions of MSCs may be impacted by factors such as growth environment or donor characteristics.

Additionally, the Consortium has identified the need for further characterization of MSC-based products in order to better understand the diversity amongst subpopulations of these cells. FDA researchers are working on ways to better characterize MSCs, such as through development of assays and screening for MSC molecular markers or other characteristics that correlate with biological properties of MSCs.  By identifying these correlative characteristics, researchers hope to develop ways to characterize MSCs with measurements that more reliably predict the biological functions of MSC-based products.

Specifically, the Consortium has performed research contributing to understanding the differences between samples from different donors and  the effects of cell passaging on the differentiation capacity, gene expression, and function of MSCs (Lo Surdo & Bauer, 2012; Lo Surdo, Millis, & Bauer, 2013; Bellayr et al. 2014).

The Consortium conducted an extensive membrane proteome analysis of human bone marrow MSCs (Mindaye et al., 2013a) and proteomic analysis of culture-expanded MSCs (Mindaye et al., 2013b), resulting in datasets which can serve as a basis for further research and understanding of MSCs.

The Consortium has also developed a novel immune inhibition assay in order to investigate the immunosuppressive functions of MSCs, with the goal of improving understanding of the immune-inhibitory activity of MSCs from different donors, at different passages, or grown under different conditions (Nazarov, C., Lo Surdo, J., Bauer, S. R., Wei., C-H. 2013).

In the future, the Consortium will continue to develop and refine quantitative methods to assess the biological characteristics of MSCs and to identify molecular and other characteristics of MSCs that correlate with biological functions of MSCs.
