How to find a clinical Trial (2019 Update)

The decision to join a clinical trial is a personal one, which I believe is best made between the person with type-1 diabetes (or parents) and their doctor.  However, I know that some type-1s don't have regular endocrinologists, and also some doctors don't tell their patients about available trials.  Therefore, I've put together this blog on how to find clinical trials, so that people with type-1 diabetes, who want to, can find trials to discuss with their medical team.

The web pages discussed below have a wide range of goals, so you will find trials aimed at curing, preventing, and treating type-1 diabetes, and also the complications caused by type-1 diabetes.  These trials also include many different methods: new drugs, new devices, diets, psychological treatments, surgeries, etc.

If you know of any web site useful to finding T1D studies, which is not on this list: please send it to me, so I can add it!

Web Sites That Search For Clinical Trials

JDRF has a good web page to find clinical trails based on age and location: https://www.jdrf.org/research/clinical-trials/
(This tool finds all type-1 diabetes studies, not just those funded by JDRF.)

There is also a blog created by Jennifer Schneider which has a great map to help you find type-1 clinical trials: https://type1trials.blogspot.com/ 
The map by itself is here:

Using This Blog

When I blog about a new clinical trial, I usually link to their recruitment page, and include the names, emails, and phone numbers of the recruiters.  This information is usually with the first posting announcing that they have started recruiting.  I also include a link to the Clinical Trial Registry (often an "NCT" or "ISRCTN" number.  By following this link, you can often find even more information on the trial.  So you can search through this blog to find interesting clinical trials near you.

Other Organizations To Search

If you want to do more searching on your own, then you can check out the following web sites:

The Immune Tolerance Network (ITN) is a very interesting organization, which I view as part of the "infrastructure" of diabetes research.  They help researchers organize and run clinical trials aimed at stopping autoimmune attack, and similar subjects within the immune system.  They cover research into type-1 diabetes, and also related autoimmune diseases.  At any one time, they usually have a dozen or so studies going on, and a couple are recruiting all the time.

Because ITN runs a network of doctors who cooperate in clinical trials, their trials often recruit at many different sites all over the US (and sometimes the world), so you have more chances to enroll.  Their studies are more likely to be available near you.

The ITN's Home Page: https://www.immunetolerance.org/

Official Clinical Trial Registries

All clinical trials should be registered at some official web site, so these are the largest and most diverse places to look for a study.  In general they contain a lot of information, but are clunky to use. They are more designed for research professionals, than random people looking for a trial.

You can search for phrases like "type-1" and "diabetes" and limit your search to studies that are recruiting right now, and even by location where they are recruiting.   Personally, I've found the JDRF site has the same information and is much easier for a patient or parent to use.  But the FDA site has more info, so if you find a trial using the JDRF site, you can look up the same trial on this site, and learn more about it.

This is the official US FDA registration site for clinical trials.  It covers just about everything in the US, and many trials not done in the US are registered here as well.

This is the United Nations's official registration site for clinical trials which covers the whole world.  Searching here will find trials registered in individual country's registry databases (all the sites listed in this section, plus many more).

This is the European Union's official registration site.

Australia and New Zealand

Japan's clinical trial registry (in English).

Note: China has a clinical trial registry in English as well, but I could not get it to work:

Looking Near You

If you are near a major university or diabetes research center, you might want to "reach out" to them.  I know that UC San Francisco, Stanford, The Barbara Davis center at University of Denver, DRI (in Miami), University of Florida at Gainsville, the Joslin center and Harvard (both in Boston) are all doing multiple studies.

Google can help you find the recruiting web pages for these studies, by searching for the name of the University and following it with "endocrinology clinical trials".

Everyone Is Near The Web

Finally, If you are more a "do it yourself" person you might want to look at the Facebook group "Prevent Autoimmune Disorders".
This group is crowd sourcing a test of Vitamin-D and Fish Oils as a preventative.  You can read the information in this group, and decide weather or not to participate.

Three Months Of New Studies

One way that I find new studies which are aimed at curing type-1 diabetes, is by searching the FDA's Clinical Trial Registry. (Luckily for me, this site even works during a partial government shutdown.) In this posting, I'm going to summarize all of the type-1 studies I found which were first registered from Oct-1 to Dec-31, 2018 and which either were recruiting patients, or had been.  (I'm specifically excluding studies which were registered, but which had not yet started recruiting.)

Out of the 41 studies which started during this time, only three (7%) were focused on curing T1D.  However, I'm summarizing all of them here, to give everyone a feel for all the types of type-1 diabetes research underway, and because some people might be interested in some of the non-cure research.

I divided these studies into 6 broad categories:

1. Treatment (16 Studies)
This section included psychological techniques to improve BG numbers, technology such as apps, training to recover low BG awareness, non-insulin drugs to treat or prevent lows, etc.

2. Technology (10 Studies)
These studies were mostly aimed at closed loops, but also other forms of technology, such as meters.  The most interesting (which I will not be covering) is a triple hormone artificial pancreas: researchers at McGill University are testing an artificial pancreas which doses Insulin, Pramlintide, and Glucagon.  They hope it will remove the need for carb counting.

3. Diet (Studies)
Two low carb studies, one on something about buckwheat, and I can't remember the fourth.

4. New Insulin (Studies)
I'm not particularly interested in new types of insulin, and most of these were standard "we hope it is a little better, and a little more expensive, than you get now" type insulin.  However, two of these studies were looking at a weekly use insulin.  Called "Insulin 287", it is a background insulin, similar to Lantus, Levemir, or Tresiba, but designed to be taken once a week.

5. Basic Science (1 Study)
Basic science studies are usually done on animals or in petri dishes, however there is one being started on people.  It is studying TMEM219 also called "TMEM219 death factor" and "Transmembrane Protein 219".  This protein is clearly involved in the death of beta cells, and is sensitive to insulin-related proteins.  There is hope that it is part of the process that kills beta cells to start type-1 diabetes, and therefore if we learn more about it, we can prevent type-1.

6. Cure Focused Research (Studies)
Finally, there were three studies which were focused on a cure.  I plan to blog on each one of these separately in the coming weeks, as they are all interesting and worth an individual blog:
MER3101 (an adjuvanated Insulin B Chain vaccine)
AG019 and Teplizumab (a mash-up of Proinsulin, IL-10, a monoclonal antibody, and bioengineering)
GABA (a dietary supplement)

Ustekinumab Starts A Phase II Clinical Trial Called USTEKID

Ustekinumab was approved in the US in 2009 for treating psoriasis, which is an autoimmune disease (where the immune system self attacks skin cells rather than pancreas cells, as with type-1).  It has also been tested on multiple sclerosis, Crohn's disease, and sarcoidosis (also all autoimmune diseases).  Ustekinumab is thought to work by blocking inflammation, and specifically blocking two immune molecules called IL-12 and IL-23.


This trial will enroll 72 adolescent (aged 12-18) honeymooners (within 100 days of diagnosis).  2/3s of them will get the drug (an infusion of Ustekinumab) once every two months for almost a year, and the other 1/3 will get a placebo, as a control group.  The study will use C-peptide in response to a meal as a primary end point (measured one year after start of treatment).  There are also a bunch of secondary end points.

The first patient started the trial in Dec-2018 and they hope to finish by Oct-2022.

Other Ustekinumab Studies
You can read my previous blogging on Ustekinumab here:

Both of these studies have the same warning signal.  Both completed over a year ago, but have not yet published their results.   My experience is that studies which are successful publish quickly, usually within a year of completion, so the fact that these researchers have not yet published is a bad sign.

Ustekinumab and INGAP
A small combination study of Ustekinumab and INGAP started in November 2015 and ended in March 2017, but the results have not yet been published.

Phase-I Clinical Trial For Ustekinumab
A 20 person phase-I trial for Ustekinumab started recruiting in March 2015 and finished recruiting in May 2016 and therefore should have completed after May 2017, but the results have not yet been published.

Hydroxychloroquine (Plaquenil) Starts a Phase-II? Trial To Prevent Type-1 In Presymptomatics

This study is testing a medication, called hydroxychloroquine (HCQ) to assess safety and effectiveness to prevent individuals at risk of type 1 diabetes from progressing to type 1 diabetes.

HCQ is approved by the U.S. Food and Drug Administration as a treatment (not a cure) for malaria, lupus, and rheumatoid arthritis.  It operates through several pathways, including as an anti-inflammatory.  HCQ has been used for over 60 years, but has not previously been studied as a treatment to prevent T1D.

This Study

These researchers are recruiting 200 people who are at least 3 years old and test positive for 2 or more autoantibodies as part of TrialNet.  2/3s will get the drug and 1/3 will get a placebo and will be a control group.   The study involves 5 visits in the first 6 months, then 1 visit every 6 months for the remainder of the study (about six years).

The primary end point is the number of people who progress to having abnormal blood glucose numbers or to being diagnosed with type-1 diabetes.  (The hope is that few people getting the treatment will make this progression, as compared to the placebo group.)  The study started in Aug-2018 and they hope to finish in 2024.  Prevention studies take a long time, because the onset of type-1 takes a long time, so the researchers need to wait a long time to see if fewer people get the disease.

This trial is part of TrialNet and is being funded by JDRF.

Vitamin D and Omega-3s (EPA/DHA "Fish Oil") Start a Patient Driven Study

This study is interesting for two reasons.  First, because of what is it testing as a possible prevention of type-1 diabetes.  Second, because of how it is doing the testing.  There are lots of important discussion areas in how this study is being run: it's quite unlike anything done before.  I discuss several of these issues at the end.  This is a long posting.

I've used d-footnotes, such as [d1] for extra discussion, and r-footnotes, such as [r1] for references.  Both of these refer to extra information at the  bottom of the post.

The Basics
This study is testing Vitamin D and Omega-3s oils, specifically Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA), as a prevention of type-1 diabetes in people who have tested positive for at least one auto antibody.  Both of these treatments have been areas of interest as possible cures, prevention, or treatments of type-1 diabetes for many years and I've blogged on them many times before [d1].

A quick summary of existing research would be: there is enough to be hopeful, but no clear evidence of success.  There are a couple of case studies, and a population study or two suggesting that Vitamin D or Omega-3 might be effective.  But there are also studies which suggest that these treatments don't help.  This uncertainty is why there are currently seven studies running that look at this question from different points of view [d2].

This study is being driven by the parents of people with type-1 diabetes and the GrassrootsHealth organization [r1].  Funding is provided by the Children With Diabetes Research Foundation [r2].  The methodology is to recruit people who want to use Vitamin D and Omega-3 oils, to try to prevent the onset of type-1 diabetes.  Every few months, they will do blood tests, fill out a questionnaire, and report if they are diagnosed with type-1 (or other diseases).  The hope is that their rate of diagnosis can be compared to the published rates from TrialNet (and similar studies) to see if the treatment prevents or delays the symptoms of type-1 diabetes.

I usually cover intervention trials, and this is not an intervention trial.  The organizers describe it as a "field study", but I would describe it as between a population study and a registry.  All of these terms (field, intervention, population, and registry) are described in [d3].  Intervention trials are the highest quality, and the only type of trial accepted by the FDA in an approval process.  But all types of trials add to our knowledge and can spur more research.

The Vitamin D / Omega-3 T1D Action Project (PreventT1D)

The idea behind this project is pretty simple: TrialNet participants who test positive for at least one autoantibody volunteer to take Vitamin D and Omega-3s and report if they are diagnosed with type-1 diabetes.  Participants will be counseled to try to get their Vitamin D level up to 40-60 ng/mL and their AA/EPA ratio (a measure of Omega-3s) below 3:1, but the final decision about supplements and dosing will be up to the patient.  The goal is to compare results with other TrialNet participants.  Over many years of operation, TrialNet has published good data on how long it takes (on average) to see type-1 diabetes symptoms, depending on how many autoantibodies you have.  You can see my blog on this here:

So, if they do their analysis right and enough people are involved, it should be pretty obvious if the treatment prevents or delays type-1 diabetes.

But it is important to realize, that this is not an intervention trial, and not even an old-school population based study.  This is "Web 2.0" / "We Are Not Waiting" philosophy applied to scientific research, which means that they are purposefully doing things very differently than a classic intervention study.  A lot of people's opinions of this research is going to boil down to attitudes about how important standardization is, how successful current research procedures are, and how much benefit is found in trying non-standard research techniques.   

The plan is to run the study for 5 years, with a possible extension if people want to participate for longer.  The end point of interest to the type-1 community is "incidence and progression of diseases listed on the questionnaire (with tracking of specific lab markers for study sub-set(s)) as they relate to any of the nutrients studied and their corresponding lab test results".  Each family will choose their own supplements, and control their own dosages (although there are recommended brands and dosages).  There is no control group, and no discussion of blinding the data analysis [d4].  Also, they will enroll as many people as possible, and don't have a set duration, so I don't know when we can expect the first published results.

I have been told that they will be measuring A1c, C-reactive protein (a measure of inflammation, not to be mixed up with C-peptide), D3 levels, and AA/EPA ratios, every three months, but I have not found a published source for that.

The PreventT1D study is a T1D focused part of the much larger D*action project.  The D*action project is a 15,000+ person study looking at Vitamin D supplementation in general and is run by the GrassrootsHealth organization.  Their goal is to increase awareness of the health benefits of Vitamin D and encourage people to take Vitamin D supplements.  (Their phrase is "moving public health messages regarding vitamin D from research into practice".)  The entire Vitamin D saga/controversy is far too large and complex to cover here, but I've included some discussion in [d5].

This study has already started recruiting.  You can join using the web here:
Since this trial is being run over the Internet, and all you need to do is take over the counter supplements and mail in your samples for testing, you can participate from anywhere and you don't ever meet with a doctor.

The primary investigator for the type-1 diabetes part of the study is Dr. Michael Clare-Salzler from the University of Florida.  The overall investigator is Cedric F. Garland.  The information sheet for patients is here: https://daction.grassrootshealth.net/research-subject-information-sheet/

More information is available at these web sites:

(Note that the three web pages listed in this section are my primary sources for information about this study.  When they conflicted, I generally used them in the order presented here (first the D*action web page, then the PreventT1D web page, and finally, the Facebook group.)

Worrisome Issues
There are several aspects of this study which I find worrisome:

No Standardized Treatment 
This is a big issue:  Patients in this trial are not all taking the same treatment.  Although Vitamin D and Omega-3s get most of the press, the "cocktail" listed on the web page actually lists five treatments (DHA, low dose aspirin, mulitvitamin with antioxidants, green tea extract, and Vitamin D).  However, no doses or suppliers are listed, which means that everyone is going to end up taking something different.  (And most of those treatments are unregulated, so the difference between brands could be huge.)  Obviously, in standard intervention trials, this would be completely unacceptable.  Even in this population trial, it may make it hard or impossible to interpret the results, since there really isn't one population being studied.

Pay To Play
This trial requires participants to pay GrassrootsHealth (the official organizer) for Vitamin D and Omega-3 tests.  See more details in [d6].  I've never seen a serious medical trial done on type-1 diabetes in the US where the participants need to pay the organizers to participate.  Obviously, this skews the people who participate (only those who can pay), but it is not illegal or against FDA regulations [r3].  It does bring up some ethical issues (which I will not discuss here).  The cost of testing will be about $600 for Vitamin D only and $1000 for both Vitamin D and Omega-3s, and more if you choose to participate for longer than 5 years.  Participants will also pay for the supplements they use.  The Children With Diabetes Research Foundation has a program to assist with funding for families who have a child with T1D but cannot afford the cost of the testing.  See their web site for details.

No trial registration / No Set Size or Patient Groups
This trial is not registered with the FDA's clinical trial registry, nor with any of the international trial registries.  Registration is only required for intervention studies for FDA approvals, but many population trials and registry trials do voluntarily registration, but this group has not.

Trial registration typically includes how many people will be enrolled, and if there are different groups within the study, how those groups will be defined.  This information makes it clear how long the trial will last, and gives some understanding of how the data will be analysed.  Since this study is not registered and that information is not publicly available for T1D participants, it is hard to know what results will be published.

Vague Endpoints
Some trials publish very specific end points.  These often include (a) the importance of the end point in terms of being primary, secondary, or other, (b) what is being measured, (c) how it is being measured, and (d) when it is being measured.  But some trials publish only vague end points.  For example, they might omit the exact method used.  However, this study is the most vague that I've ever blogged on.  End points are not listed as primary, secondary or other.  No time frames are given.  And even what is reported is listed just as "lab tests" and "incidence and progression of diseases listed".  This is a previously unseen level of vagueness, and leaves open the possibility of "cherry picking" and "results switching" [d7] of data.

Other weaknesses of this study are discussed briefly in [r4], which more broadly discusses hype and hope in type-1 diabetes research.

The Three Big Questions

At the end of the day, I think each of us needs to come to our own decisions on the value of this kind of research.  But I do think we should frame our thinking in terms of the following three questions:

Will We Benefit From This Study?
This is not as easy a question to answer as you might think.  Some people will say that any research helps, and therefore (of course) this research helps.  But others are not so sure.  It's not clear to me if this research could ever be published in a scientific journal, and if not, does it really contribute?  If you look at the "Worrisome Issues" listed above, there are several good reasons why this study may not be taken seriously, and if people don't trust the results, then what is the point of doing the study?

Studies involve direct costs, indirect costs, and opportunity costs.  Prevention studies (such as this one) typically need to enroll lots of people and follow them for many years, so all these costs are high.  Therefore the question of "at the end of the day, will anyone trust the results" is huge.

Will This Study Interfere with Intervention Studies?
There is no question that intervention studies are much more powerful than population studies (or field studies or registries, whatever this study is called).  So another point to consider is: will this study make doing intervention studies harder by siphoning off potential participants.  There is real controversy about this.  The people interested in this study often say things like "I tested positive for two autoantibodies and was told there was nothing I could do.  I don't want to do nothing."  On the other hand, I've heard researchers say things like "TrialNet is running several prevention studies that are recruiting right now, and they'll fly people to centers to participate, etc."  So there is a real difference of perception about whether this study is the only one available or whether it is recruiting in competition with more scientifically powerful intervention studies. [d8]

I will add one data point to the controversy: I live in Silicon Valley (near San Francisco) and we have lots of studies going on here.  At the last JDRF OneWalk there was a joint flyer given out which listed 23 studies recruiting near me right now.  Exactly 1 of these studies (Abatacept, NCT01773707) is aimed at the same group as this PreventT1D study is aimed, requiring two autoantibodies and an age of 6 or higher.  So there is no question that people with one autoantibody or under 5 years old could enroll in the PreventT1D trial, but not in any other local trial.  However, people who are older and have two autoantibodies do have a choice.  But in that case, enrolling in one in might prevent enrolling in the the other.  Even if one person is allowed to enroll in both, it may not be known if the results are due to one or the other treatment, which could make analyzing results tough.

Is This Study A Pathfinder?
Another important question is "Even if imperfect, this study might be a trailblazer to a new way to do clinical trails, and if it is, is that worth supporting even if there are some problems in this specific study?"  When doing something new, the first example often has some problems. Yet, if we abandoned new things at the very first problem, then we would never find the new directions that make the big improvements possible.

On a similar note, what if this study is on the right track to a new kind of study, but has pushed things a little too far?  This is also a common mistake in people experimenting with new ways of doing things. Again, as an experiment in research methodology, it might be worth supporting so that the next project learns from this project, and gets the benefit of crowd sourcing research subjects without the problems caused by pushing the technique quite as far as this team has chosen to push it.

A related idea is that this project might benefit future research if it pushes more conventional researchers to use the web more in the future.  If it encourages researchers to use the web more effectively, to integrate the web into every aspect of running an intervention clinical trail, then it might be worthwhile to support, even if the specific data coming out is less useful [d8].

My Opinions On This Study

1. This is a question that is important to people in TrialNet (and their parents), and so I'm happy to see research focused on this question.  This is a case where there is real scientific controversy, and more studies are needed.

2. I think the idea of harnessing the Internet (and its large, connected population of interested people) is a great idea.  I hope it gets reused and refined in future research, and that conventional researchers incorporate more "Web 2.0" in their methodologies.

3.  I think the combination of pay to play, vague endpoints, different supplements/dosing for different people, and no set size or groups, make this particular study in between a scientific study and a marketing campaign for the company doing the testing.  And I'm profoundly nervous about that.

4. I'm looking forward to the publication of results from this study.  How these results are published and what information is included in the publication(s) will help me to understand if this is a marketing ploy to manipulate science or a new way to leverage the Internet to do large scale science in a way not seen before.  When the results are published, some of the things that I'll be looking at carefully are:
  • Is the publication peer reviewed?  Is it treated as a scientific result or as raw material for marketing literature.
  • Are the results published in a way which makes them easy to compare with existing results from TrialNet (and elsewhere).
  • Who was included in the study and who was excluded, how were trial drop outs reported?  This can be an issue with any registry based trial, but is especially an issue with this study.  The big question will be: if you loose contact with a participant, how does that impact your results.  [d9].
  • More generally, how were the various worrisome issues (discussed above) dealt with?  Were they ignored?  Was the data analysed specifically to address them?  Was a larger study size effectively used to lower the risk of spurious results?
5. At the end of the day, I'm unsure if this is a worthwhile trial or not, but because I'm unsure, I'm looking forward to seeing how it turns out.  I may change my mind when I see the methodology behind their published results.  And if the only output of this is a bunch of self-serving press releases, then I will certainly change my mind.  However, I think it is important to give new ideas the benefit of the doubt at least until we see the results.  I do think that this group is trying to push the envelope of what is a scientific study (which is why some researchers don't consider it a "real" study).  Since I'm a "Silicon Valley Boy" I totally support trying new things and seeing what happens.  If we don't try something because we don't know what will happen, then we will never try anything new.   And with this trial, safety is not an issue.

Extra Discussion

[d1] You can read a summary of Vitamin D research aimed at prevention here, but it is 6 years old:
You can read all my blogging on Vitamin D here:

For Omega-3s, I've only blogged on one study (on DHA) which has completed, and it was unsuccessful:
but there might be a few more out there that I missed.

[d2] Right now, there are at least 7 intervention trials testing Vitamin D and/or Omega-3s:
* One tests Vitamin D only on honeymooners aged 10-21.   (NCT03046927)
* One tests Vitamin D and Omega-3s on honeymooners and established, children and adults (for a total of four groups.  Within each group, half get just Vitamin D and the other half D and Omega-3s  (NCT03406897).  This is the POSEIDON trial.
* Four studies using Viatmin D and Diamyd in combination with various other treatments, on various populations.  (NCT02352974, NCT02464033, NCT02387164, NCT03345004)
* One study of Vitamin D and Saxagliptin (a type-2 medicine) on people with adult onset type-1 diabetes.  (NCT02407899)

The NCT numbers above are the FDA's clinical trials registry number for each study.
The list above only includes trials registered in the USA, so I would expect there to be several population or registry studies not included.  Foreign intervention studies are usually included, but there could be one or two which are listed elsewhere.

[d3] Types of studies:
Clinical Trials: A group of similar people are divided up: some get a treatment (an intervention) and some don't.  These are the best form of clinical trials, and the only form accepted as evidence by the FDA when applying to get a new drug approved.
Population Study: A group of people naturally doing one thing, are compared against a group of people who naturally do not do that same thing.
Field Study: (Usually used in ethnography and social sciences, not medicine.)  A study where researchers measure what is happening in the world, without trying to change it, or comparing one group to another.
Registry Study: The researchers register a (hopefully large) list of people who are all similar in some way (for example, by treating a specific disease with a specific drug), and then gather information about those people.  These studies are often exploratory, looking for differences between people in the registry and "average" people.

[d4] This study will use TrailNet data as a comparison group, but this is not a control group.  In particular, some TrialNet participants may be taking Vitamin D or Omega-3s, and that would hurt the comparison.  Also, using a comparison group from a different study creates problems that would not occur if they had their own control group.  Even though there is no control group, blinding might still help in the analysis based on the treatment (comparing those who took just Vitamin D to those who also took Omega-3 oils), or how many autoantibodies the people started with, or previous use of Vitamin D or Omega-3s

[d5] Traditionally, the FDA has considered a blood level of 20 ng/ml, or higher, to be a healthy level of Vitamin D.   Levels above 80 ng/ml can cause direct health problems (toxicity).  Recently there has been a push by some doctors that levels should be 30 ng/ml or higher for best health.  This is controversial, and the New York Times recently had a good (in my opinion) article on the controversy:
The doctors affiliated with Grassroots health, go farther even than this, however, and recommend 40 ng/ml to 60 ng/ml as a normal level of Vitamin D, and recommend testing to ensure you have that level, and supplements if you don't.

[d6] The GrassrootsHealth web site says that they will do the testing and lists the costs I've included.  However the WIRB document on the Facebook page says that any lab can do the tests (and does not list specific prices).   Also, there are scholarships available to people who want to participate, but can not afford to, but these are not described, although I have been told that The Children With Diabetes Research Foundation will assist those who need assistance, through GrassRootsHealth.

[d7] "Cherry Picking" is a bad science technique where data is only gathered from people (or in situations) which support the researcher's goals.  "Results switching" is a bad science technique where the researchers expect to report on one end point, but that end point does not show what they want, so they look around for some data closer to what they want, and publish that instead.

[d8] On a more personal level, the whole point of TrialNet (which is a large, multi-year, multi-million dollar project) is to screen people for autoantibodies, both to help those people and their parents, but also to recruit them into prevention studies.  TrialNet is a shared foundation for many prevention studies.  This PreventT1D trial can be viewed as a sort of crowd sourced, web 2.0, #WeAreNotWaiting competitor to TrialNet; a clear message (from some patients) that TrialNet is too slow, too exclusive, too official, too bureaucratic, too limited, and so on.

[d9]  It is clear to me that this study will be large enough, so that by excluding certain people, you can come up with any results you want.  So it will be important that the published results document exactly how people are included, excluded, and how drop outs are handled.

Golimumab Update

Golimumab (sold as Simponi) is an immune system modulator, which has been approved in the United States and many other countries for treatment of several autoimmune diseases, so testing it on type-1 diabetes makes a lot of sense.  Simponi has already been approved to treat rheumatoid arthritis, psoriatic arthritis, ulcerative colitis, and ankylosing spondylitis.

Golimumab is a monoclonal antibody, which is an artificially created antibody which targets one very specific molecule in the body.   If a disease is caused by that molecule (or a cell marked by that molecule), then using a monoclonal antibody to target it is promising.  Golimumab targets tumor necrosis factor alpha (TNF-α) which causes inflammation, and is well known to be involved with type-1 diabetes. 

There are three on-going clinical trials of Golimumab (Simponi):

T1GER: SIMPONI® to Arrest Beta-cell Loss in Type 1 Diabetes
Who: 84 people aged 6-21 with honeymoon type-1 (first 100 days)
What: 52 weeks of treatment
When: Started Aug-2016 and expects to finish May-2020 (fully enrolled in Aug-2018)
Where: 33 sites in the USA (but they are no longer recruiting)
Run by: Janssen Research & Development

SIMPONI (Golimumab) Therapy in Children, Adolescents and Young Adults With Pre-Symptomatic T1D
Who: 30 people aged 6-21 with two or more autoantibodies, but no "classical" symptoms of T1D
What: 26 weekly injections
When: Started Oct-2017 and hopes to finish July-2021
Where: Colorado, Finland, Sweden  (they are still recruiting new people)
Run by: Janssen Research & Development

Targeting Beta Cell Dysfunction With Liraglutide or Golimumab in Longstanding T1D
Who: 30 people aged 18-50 who have had type-1 for more than 3 years
What: 8 weeks of treatment
When: Started Aug-2018 and hopes to finish June-2020
Where: Idaho and Washington  (they are still recruiting new people)
Run by: Benaroya Research Institute

I like this as a complete program.  These three studies cover Golimumab from many different points of view: people before they are diagnosed, honeymooners, and people with longstanding type-1. Two of the studies are for children 6-21 years old, and one for adults 18-50.  All are reasonable size.

The downside, is that we have to wait until 2020 to see results.  The good news is that by 2021, we'll have results from three different studies to look at.

Curing type-1 diabetes in people with established type-1 is generally thought  to require two successes.  First the autoimmune attack must be stopped, and second beta cells must be regrown.  Golimumab targets the autoimmune attack, but is not known to regrow beta cells.  By itself, such a treatment might cure presymptomatic or homeymoon type-1 (because those people still have some beta cells), but is unlikely to cure established type-1.

JDRF Funding for a Cure 2018

In the US, we are in the "Walking Season" when JDRF asks us to walk to raise money for a cure. So I'd like to do my part, by reminding you all of how important JDRF is to the human trials of potential cures for type-1 diabetes, which I track.

Let me give you the punch line up front: 69% of the treatments currently in human trials have been funded by JDRF. (And the number is 86% for the later phase trials.) This is a strong impact; one that any non-profit should be proud of.  Below is a list of all the treatments, grouped by phase, and separated into groups that JDRF has funded, and those JDRF has never funded.

Many of these treatments are being tested in more than one clinical trial.  For example, the "Polyclonal Tregs" treatment is running at least two trials, but since they are both testing the same treatment, it is only one item in the list. The list below uses the following marks to show the nature of the treatments:
    Established: One or more trials are open to people who have had type-1 diabetes for over a year.
    Presymptomatics: One or more trials are open to people who have 2 or more autoantibodies, but have not yet started showing symptoms of type-1 diabetes.
    Prevention: This treatment is aimed at preventing type-1 diabetes, not curing it.

I give an organization credit for funding a treatment if they funded it at any point in development; I don't limit it to the current trial. For example, JDRF is not funding the current trials for AAT, but they did fund earlier research into it, which helped it grow into human trials. I also include indirect funding of various kinds. The JDRF funds nPOD,  ITN, and several other organizations, so I include research done by these other groups as well.

The Difference Between Phase-II and Phase-II? Trials
Phase-II trials are "classic" phase-II trials; they are done after a successful Phase-I trial in type-1 diabetes.  What I call Phase-II? trials are done on known safe treatments, so they don't need Phase-I trials, but have never been tested on type-1 diabetes before.  These Phase-II? trials might be Phase-II from the point of view of size and safety, but they are Phase-I in terms of effectiveness, so I'm putting them in their own category.

Cures in Phase-III Human Trials
Summary: currently there is only one treatment in a phase-III clinical trial, and that is aimed at prevention.  It is funded by JDRF:
  • Oral Insulin (Preventative)
Cures in Phase-II Human Trials
Summary: there are 22 trials in phase-II, and 18 of them have been funded by JDRF, while 4 have not. Here are the treatments that have been funded by JDRF:

  • Alpha Difluoromethylornithine (DFMO) by DiMeglio
  • GABA by Diamyd
  • GNbAC1 by GeNeuro (Established)
  • Golimumab by Janssen
  • Golimumab by Greenbaum (Established)

  • Liraglutid (Presymptomatics)
  • NNC0114-0006 and Liraglutide by Novo-Norsk
  • Rapamycin Vildagliptin Combo by IRCCS (Established)
Cures in Phase-I Human Trials
Summary: there are 24 trials in phase-I, and 15 of them are funded by JDRF, while 9 are not. Here is the list funded by JDRF:
  • Alefacept by TrialNet 
  • ßAir by Beta-O2's at Uppsala University Hospital in Sweden (Established) 
  • TOL-3021 by Bayhill Therapeutics (Established) 
  • CGSF by Haller at University of Florida 
  • Exsulin and Ustekinumab by Rosenberg at Jewish General Hospital, Canada (Established) 
  • Golimumab by (Presymptomatics)

  • Substance P by Vanilloid Genetics at Hospital for Sick Children Toronto (Established)
    Summary of all Trials
    59 in total
    41 funded by JDRF
    So 69% of the human trials currently underway are funded (either directly or indirectly) by JDRF. Everyone who donates to JDRF should be proud of this huge impact; and everyone who works for JDRF or volunteers for it, should be doubly proud.

    Just Looking at Trials on Established Type-1 Diabetics
    16 of these treatments (27%) are being tested on established type-1 diabetics.
    Of these, 9 are funded by JDRF.
    So 56% of the trials recruiting established type-1 diabetics are funded by JDRF.

    Compared to Last Year
    In 2017 there were 55 treatments in clinical trials, in 2018 there are 59 (growth of 7%).
    In 2017 there was 1 treatment in Phase-III trials, in 2018 there is one (no change).
    In 2017 there were 22 treatments in Phase-II trials, in 2018 there are 22 (no change).
    In 2017 there were 8 treatments in Phase-II? trials, in 2018 there are 12 (growth of 50%).
    In 2017 there were 24 treatments in Phase-I trials, in 2018 there are 24 (no change).

    A Little Discussion
    This year there are no phase-III trials aimed at curing type-1 diabetes, and that's been true for many years.  Indeed, since I've tracked research, there has never been a phase-III trial aimed at people with established type-1.  Back in the 2000s, there were a couple aimed at curing honeymoon type-1, but none were successful, and none have started for years.

    That's discouraging, because it means we are a long way from a cure.  However, for me, it's a reason to donate.  Money is the thing that is going to move the Phase-II studies into Phase-III studies, and the Phase-I studies to Phase-II, create more Phase-I studies, and so on.  And if we think "nothing looks promising in the next few years, so I won't give money" that results in nothing looking promising in the future, either.  If you're worried about your money going to non-research, then you can do what I do: fill out the attached form or go to the following website and send it in with your donation:  http://thejdca.org/good-giving-landing-page/  (Unfortunately I don't know how to do this for on-line donations.)

    How I Count Trials for This Comparison
    • I give an organization credit for funding a cure if it funded that cure at any point in it's development cycle. 
    • I mark the start of a research trial when the researchers start recruiting patients (and if there is any uncertainty, when the first patient is dosed). Some researchers talk about starting a trial when they submit the paper work, which is usually months earlier. 
    • If there are different clinical trials aimed at proving effectiveness as a cure and as a preventative, or effectiveness in honeymooners and established diabetics, then those are counted separately. 
    • For trials which use combinations of two or more different treatments, I give funding credit, if the organization in the past funded any component of a combination treatment, or if they are funding the current combined treatment. Also, I list experiments separately if they use at least one different drug. 
    • The ITN (Immune Tolerance Network) has JDRF as a major funder, so I count ITN as indirect JDRF funding. 
    • I have made no attempt to find out how much funding different organizations gave to different research. This would be next to impossible for long research programs, anyway. 
    • Funding of research is not my primary interest, so I don't spend a lot of time tracking down details in this area. I might be wrong on details. 
    • I use the term "US Gov" for all the different branches and organizations within the United States of America's federal government (so includes NIDDK, NIAID, NICHD, etc.) 
    • I don't work for the US Gov, JDRF, or any of the other organizations discussed here. I have a more complete non-conflict of interest statement on my web site. 
    Some Specific Notes:
    • GNbAC1 by GeNeuro used JDRF's nPOD project.
    • NextGen's ProTrans product is a form of Wharton's Jelly, and JDRF has funded related research into Wharton's Jelly, but has not funded this program specifically, so it is listed as non-JDRF.
    • I'm removing Dr. Faustman's BCG research from my list of potential cures.  For more information read this blog:
      https://cureresearch4type1diabetes.blogspot.com/2018/09/every-year-in-september-or-october-i.html and for even more details
    • Oral Insulin: This trial was a phase-III trial, meaning that it was large and designed to provide enough information so that if, if successful, the treatment could be widely used. However, as it turned out, only part was successful, and that part was phase-II sized, so I don't think we will see widespread use based on this trial alone. You can think of this as a phase-III trial with phase-II results.
    • Serova's Cell Pouch and DRI's BioHub: These two clinical trials are both testing one piece of infrastructure which might be used later in a cure. They are testing a part of a potential cure. However, in both cases, the clinical trials being run now require immunosuppression for the rest of the patient's life, so I'm not counting them as testing a cure.
    • Substance P at Hospital for Sick Children Toronto: This trial is avoiding the honeymoon period by testing for insulin production.  Patients must inject more than 1/2 unit/kg to be accepted, therefore they will accept recently diagnosed people, if they are injecting enough insulin to be passed the honeymoon.  I'm counting this as "Established".
    This is an update and extension to blog postings that I've made for the previous seven years:
    Please remember that my blog (and therefore this posting) covers research aimed at curing or preventing type-1 diabetes that is currently being tested in humans. There is a lot more research going on than is counted here.

    Please think of this posting as being my personal "thank you" note to all the JDRF staff, volunteers, and everyone who donates money to research a cure for type-1 diabetes:
    Thank You!

    Finally, if you see any mistakes or oversights in this posting, please tell me! There is a lot of information packed into this small posting, and I've made mistakes in the past.  As in previous years, I'll be at the Santa Clara (California) JDRF One Walk. New this year, I'll be part of the Bigfoot Team.  Come by and say "hi", or strike up a conversation about research.  I love to talk about research!
