Can A Rotavirus Vaccine Prevent Type 1 Diabetes In Some People?

In this blog posting I'm discussion an observational study, that is, a study where different groups of people are observed to see if their differences cause more or less disease.  This is quite different than the intervention studies that I usually cover.  Intervention studies are much better controlled and their results are more likely to be supported by future research.   However, I though this study was interesting enough to discuss even as an observational study.

This is the Reuters headline:
Rotavirus vaccination tied to lower rates of type 1 diabetes

For comparison, this is the headline from The Scientist:
"Results from an observational study find that the introduction of a routine vaccine in Australia coincided with a fall in the incidence of the autoimmune condition."

So what data did they look at, and what did they see?

They looked at people diagnosed with type-1 diabetes in Australia, and compared the 8 years before 2007 to the 8 years afterwards.  That was the year the Rotavirus vaccine was universally introduced to Australia.  This analysis covered about 16,000 children who were diagnosed with T1D.  What they saw was that the number had been stable up until 2007, at 8.7 per 100,000 kids [d1].  However, after they started giving the vaccine to all babies, the rate dropped to 7.8 per 100,000, a drop of 14%.
Graph is from the published paper, and is presented
 for educational purposes only.


Discussion

Rotavirus or 2007?
For me the big, obvious question is: did the type-1 diabetes rate drop because of the Rotavirus vaccine or because of something else that happened in 2007?  In a sense, this is the only question that really matters.  If you only look at this study, there is no way to tell.  However, this research group has been studying the connection between Rotavirus and T1D for many years, and they do think the two are related, and it's not just some random 2007 thing.

I did a very quick literature search, and found several studies (including some done previously by this group), which showed a connection between rotavirus infection and type-1 diabetes.  There were also some computer simulation studies, and some "mechanistic" studies (showing how a Rotavirus infection might cause or speed up the development of type-1 diabetes).  So the idea that the two are linked is not far-fetched.

Just One Study? / What about other research?
Another question is: Are there other studies showing that a Rotavirus vaccine might lower type-1 rates?  Or, is this the only one? 

In my literature search,  I only found one similar study done in people.  The researchers compared type-1 diabetes rates in children who had been vaccinated against Rotavirus to children who had not (all born in the same year).  Rotavirus vaccination did not lower type-1 rates in this study [d3], and that is not promising.

I very much hope that these researchers perform similar analysis in other countries which introduced universal Rotavirus vaccination.  If they see that county X introduced the vaccine in 2010, and saw a drop in type-1 in 2010, that does two things at once: it confirms this study, and it suggests that the vaccine is important, rather than the year.

Does Prevention Matter? / Does 14% Matter?
I know many people touched by type-1 diabetes don't care about prevention.  And I understand that; after all, in a sense prevention is too late for them.  But I will continue to care about prevention, even though it will not help my daughter.  First, because I think we might learn something from a prevention that might lead to a cure in the future.  That is not always true, of course, but it certainly is possible.  Second, because someday my daughter may have kids of her own, and a prevention for my grandchildren would be worth a lot to me.  Third, just in general, I want the world to be a better place even if my family doesn't personally benefit.  And prevention will surely help many people in the future.  (Of course, there is a counter argument: that prevention will cause research money aimed at a cure to "dry up", because there will be less and less need of it in the future.)

Finally, some people will belittle the 14% drop.  They will point out, that's not a lot, and many people will still get type-1.  That is true, but for me, it's besides the point.  Right now, we have nothing that lowers the chance of type-1 diabetes after a person is born [d2].  So going from nothing to one thing, and going from 0% to 14% are both big improvements.  I don't think we should let the perfect become the enemy of the good when it comes to solutions.  A drop of 14% (if confirmed by future research) is an important first step.

Details

[d1] I assume those numbers are just for people diagnosed between 0 and 4 years old.  They are much too small to be everyone diagnosed with type-1 diabetes.  Total type-1 rates in the US are generally between 1 in 250 and 1 in 500.

[d2] Universal Rubella (German Measles) vaccination is thought to lower the rate of type-1 diagnosis in the population (but no where near 14%).  However, it is generally believed that this is caused by preventing measles in pregnant women since contracting Rubella during pregnancy significantly raises the chance that the child will (eventually) be diagnosed with type-1.  So this is a pre-birth intervention.
https://www.diapedia.org/type-1-diabetes-mellitus/2104282116/the-congenital-rubella-syndrome-and-diabetes

[d3] The exact quote was: "The adjusted relative risks (with 95% confidence intervals) were 0.91 (0.69-1.20) for T1D ... in vaccinated children compared with unvaccinated, suggesting that oral rotavirus vaccination does not alter the risk ... T1D during 4-6 years follow-up after vaccination."
This study covered 500 children.

My Theranos Story


I'm listening to the book "Bad Blood" by Carreyrou.  It is a fun read, and I think it is very valuable for me.  I'm a big cheerleader of Silicon Valley; a strong proponent of the risk-taking culture found here.  And I also follow a lot of medical research (obviously).  Therefore it is even more important for me to be reminded of the weaknesses both of Silicon Valley specifically and medical research in general.  This book is all about those weaknesses.

My Theranos Story

I'm on a mailing list of parents of kids who have type-1 diabetes.  It is a great resource, and I recommend everyone connected to type-1 diabetes join some sort of support and information sharing group.  In Dec 2013 there was a posting about a Silicon Valley blood testing start up called Theranos, that was going to make cheap, quick blood tests available which used only a few drops of blood.  Their first site was a Walgreens in Palo Alto.  They had a price list online (as I remember) and C-peptide tests were just a couple of bucks.  Less than the cost of a sandwich.  I had this idea to invite a bunch of parents and children from the email group to meet at the Walgreens one weekend morning.  We could all get tested, get the results, and maybe afterwards go out for ice cream later and talk about type-1 diabetes.  Since the parents would mostly have normal C-peptide numbers, and the kids (with type-1) would have nearly zero C-peptide numbers, it would immediately be obvious if the test worked or not.

However, based on many years of blogging about research, before I suggested this to the group, I figured I'd look up the research on their new testing machine.  So I did some of my standard queries on Pubmed (a US government database of publications), and scholar.google.com (Google's big research database), and clinicaltrials.gov (the FDA's clinical trials registry), and a few other places.  Nothing.  Not one paper.  I was really shocked.  Normally, you can't sell a treatment until it has gone through at least four human trials, so I was really surprised that I could find nothing for this new testing system.  (I did not know at the time that tests were regulated by a completely different US government agency, and in a completely different way, than treatments.)

Anyway, desperate for information, I looked online for the company's organization and basic balance sheet.  At that time, I had worked for Silicon Valley start ups for over 20 years, and I knew how to read a balance sheet, and how stock worked.  But there was none of that.  The only information that I found was Theranos's board of directors.  My years of working for start ups had given me experience with many different boards of directors, so I knew what to expect.  Or I thought I did.

The first name was George Schultz.  A guy famous for lying, and for being a Secretary of State (ie. foreign relations).  The next name I noticed was Henry Kissinger.  Another guy famous for lying, and foreign affairs.  [Note: I'm telling this story from my point of view.  I realize that other people may consider these two famous for other things.]  There was some long time senator (Sam Nunn, I think), and a big time general (Mattis?).  I was flabbergasted.  Why were these guys on the board of directors for a medical device company?  Where was the medical expertise?  Where were the expert venture capitalists (VCs) who funded medical devices?  Where were the people who had actually run a company before?  It was like a Saturday Night Live skit.

I thought about this for a while.  Should I judge a company based on its board of directors?  Maybe there was some reason all these guys were there.  Shouldn't I be deferential to all these famous, important people?  Maybe I could imagine some good reason for this.  But then I caught myself.  The only reason I was even looking at their board of directors was because there was no actual/published clinical trials showing the testing system worked.  There is no excuse for that.  If a treatment for type-1 diabetes had zero clinical trials, I would ignore it.  Well, I would wait until they started a clinical trial, and then evaluate it based on the results.  I should have the same standard for testing companies;  I would not evaluate their board of directors.

So I dropped the idea of getting a crew together to get tested by Theranos.  I decided to wait until they published results showing their tests worked.  They never did.  Years later Carreyrou published a series of newspaper articles describing what a fraudulent house of cards it was.

Learning From Theranos

After reading the book, and reflecting on my own experience with Theranos, a question popped into my head: why was it that in a couple of hours on a weekend morning, with no special insider data, and making a minor decision about how to spend a morning, I decided Theranos was not worth even a little time.  Compared to the venture capitalists (VCs) who spent weeks researching Theranos, could ask for insider information, had direct contact with the CEO/founder of the company, and were making million dollar decisions, and yet they decided Theranos was worth it.

Was I just lucky? Maybe.  But I do think I was helped by two things: (1) when I was making the decision, and (2) that I did not have direct contact with Theranos.

When Decisions Get Made
I had a big advantage over most of the investors, in that I was making my decision relatively late in the game, and therefore it was completely reasonable for me to expect public results.  When those were not available, I realized there was a problem.  Most of the investors made their decisions much earlier in the process, when less data was expected to be available.  Therefore, the lack of data did not make them suspicious.  How do we avoid that problem?   In two ways:

First, be willing to delay your judgement on new research.  The VCs wanted to invest early because they would make more money that way.  We need to invest early to nurture early stage research, but we don't need to decide that one particular line of research is going to be the cure.  That decision, the decision to emotionally commit to the research (to be a cheerleader), we can hold off on.  And we should.  If you think something might be the cure, you can always donate some money initially, but wait a few years, and check on their progress, to see if it really is the cure.  (Type 1 is forever, so waiting a few years is reasonable.)

Second, be willing to change your mind as the situation changes.  Most people have a hard time changing their minds, and this was on display during the whole Theranos saga.  Several VCs who had decided the company was going to revolutionize testing in 2006 still believed it in 2016, by which time they should have known better.  A good scientist changes their mind when new data is available, but that is the easier part.  The harder part is to change your mind when no new data is available, but forward progress should have resulted in new data, but hasn't.  The hard part is to realize when no new data is (in fact) bad data.

Answer The Right Question
The right question is: what is the data available that shows this is working (compared to the data that should be available).  The answer to that question was obvious when I did my web searches.  However, the questions that most of the investors were asking were different: Is what Elizabeth Holmes says is going to happen, really going to happen?  Is she going to revolutionize blood testing?  Is she telling the truth?  Those questions are much harder to answer, much more emotional, much more personal, than the question that I tried to answer.

Asking the right questions is harder than it sounds.  Humans have been making decisions about people and trustworthiness for over 100,000 years.  Our brains are hardwired to do that, because we lived and worked in small groups who knew each other well.  We worked with them every day and for our whole lives.  The scientific method has existed for only a few 100 years.  It is not the go-to method our brain naturally uses.  But the world has changed so that we are now making decisions about people who we fundamentally do not know, not in the way our brains evolved.

I do think that every one of us, when presented with new research, can ask the right question.  The moment we even start to think about "is this person right" or "are they trustworthy" or "are they going to change the world", to just immediately de-personalize the question: do they have the data that they should have at this point in the research?  Ignore excuses; ask about data.

Finally

These are a little off the beaten path, but well worth a read:

Azithromycin Starts A Phase-II? Clinical Trial (AIDIT)

Azithromycin is an antibiotic which has been available since 1988, and is widely prescribed, with a good safety record.  Antibiotics are effective in curing bacterial diseases, but not viral diseases.  This trial is the first I've covered where an antibiotic was tested to treat, prevent, or cure type-1 diabetes, so it represents a new treatment path.

Why Azithromycin?

There are several different theories about what causes type-1 diabetes, one of which is that bacteria moving from the duodenum to the pancreatic duct causes type-1 diabetes.  The duodenum is the part of the small intestine closest to the stomach.  This is one of the "stomach flora" or "gut bacteria" theories which have been in the news recently.

If the cause is bad bacteria in the pancreatic duct, then (these researchers theorize), maybe the cure is to give the patient a dose of antibiotics to kill the bacteria, extra insulin to lower the stress on the remaining beta cells, and dietary guidance to prevent excess bacteria from moving from the duodenum to the pancreatic duct in the future.  All this would be done very quickly after diagnoses of type-1 diabetes.  That is the quick summary of the rationale behind this clinical trial.

This Clinical Trial

This trial is called the "Azithromycin Insulin Diet Intervention Trial in Type 1 Diabetes (AIDIT)" to include all three of the interventions being used.  This trial will enroll people between 6 and 16 years old, who have been diagnosed within the last 10 days, so only "just diagnosed" people can participate. 

The plan is to recruit 60 people, half of whom will get the treatment, and half will not.  The study is not blinded.  It started in Sept-2018 and they expect to finish in Dec-2021.

People will get three doses of Azithromycin per week, which is based on a protocol which has been used for years to treat people with cystic fibrosis.  On a monthly basis, they will be given extra insulin via an IV, which is designed to give beta cells a rest and help them regrow.  Finally, they will also be given dietary advice designed to have them drink less at meals, and eat meals more slowly, which is designed to prevent bacterial migration.

The study will run for a year, with C-peptide numbers being the primary end point.  There are a total of 21 different secondary end points, including time within BG range, A1c, several measures of diet, quality of life, etc.

They are recruiting at one site in Sweden:

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:
https://www.google.com/maps/d/viewer?mid=1OL5RWPz-D1FiViGpxhAjqEEv2Q2Ck_n3&ll=45.137952951318496%2C-102.69609393571398&z=5

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:

https://www.immunetolerance.org/patients/autoimmune-disease
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.

http://www.clinicaltrials.gov
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.

http://www.who.int/trialsearch/
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).

https://www.clinicaltrialsregister.eu/ctr-search/search
This is the European Union's official registration site.

http://www.anzctr.org.au/BasicSearch.aspx
Australia and New Zealand

https://upload.umin.ac.jp/cgi-open-bin/ctr_e/index.cgi
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:
http://chictr.org.cn/enIndex.aspx

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".
https://www.facebook.com/groups/preventautoimmunedisorders/
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.
https://clinicaltrials.gov/ct2/show/NCT03800875

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.
https://clinicaltrials.gov/ct2/show/NCT03794739

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)
https://clinicaltrials.gov/ct2/show/NCT03624062
AG019 and Teplizumab (a mash-up of Proinsulin, IL-10, a monoclonal antibody, and bioengineering)
https://clinicaltrials.gov/ct2/show/NCT03751007
GABA (a dietary supplement)
https://clinicaltrials.gov/ct2/show/NCT03721991

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.

The USTEKID Trial

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:
https://cureresearch4type1diabetes.blogspot.com/search/label/Ustekinumab

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.

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.
