Breakthrough T1D (formerly JDRF) Funding for a Cure 2024

Normally, sometime in October, I write a summary of all the clinical trials funded by JDRF.   However, this year I didn't, which was a mistake.  But late is better than never, so in this post I summarize the clinical trails that Breakthrough T1D (formerly JDRF) is funding as of October 1st, 2024.

I hope to remind everyone of how important Breakthrough T1D is to the human trials of potential cures for T1D, which I track.

Let me give you the punch line up front: 65% of the treatments currently in human trials have been funded by Breakthrough T1D, and this goes to 77% for the Phase-III and Phase-II studies!  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 trials that Breakthrough T1D has funded, and those Breakthrough T1D has never funded.  
 
The List, Divided by Phases

Below is the list of all treatments, divided into six phases: FDA Approved, In Process of Approval, Phase-III, Phase-II, Phase-IIΔ, and Phase-I.  Phase-II trials are "classic" phase-II trials, which are done after a Phase-I trial.  What I call Phase-IIΔ trials test treatments which never went through phase-I trials on people with T1D.  (I used to call those Phase-II? but I think using punctuation that way is confusing, so I'm using a delta instead: Phase-IIΔ.)  They've been shown safe in other diseases, so have skipped phase-I trials on people with T1D.  These Phase-IIΔ 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.

For T1D research, phase-I studies are usually about 10 people and test for both safety and efficiency.   In other diseases, phase-I trials are sometimes only done on healthy people, or only test for safety issues, but this is not the way T1D research is usually done.  Over 90% of phase-I studies are done on people with T1D, and over 90% test for both safety and effectiveness.

Phase-II trials are about 100 people, and phase-III about 300. After two successful phase-III trials, the FDA considers approval for general use.  These two studies can be run at the same time, and are often identical.  Occasionally, only one phase-III trial is required for approval. 

Approved or In Process of FDA Approval

In 2024, nothing was approved and nothing is in process of approval.

Summary of all Trials
62 in total
40 funded by JDRF
So 65% of the human trials currently underway are funded (either directly or indirectly) by JDRF. Everyone who donates to Breakthrough T1D should be proud of this huge impact; and everyone who works for Breakthrough T1D or volunteers for it, should be doubly proud.

Just Looking at Trials on Established Type-1 Diabetics
 
Of these treatments 14 (23%) are being tested on people with established T1D, of those, 9 are funded by Breakthrough T1D.  So 64% of the trials recruiting people with established T1D are funded by Breakthrough T1D.

Compared to Last Year
In 2023 there were 59 treatments in clinical trials, in 2024 there are 62 (growth of 5%).
In 2023 there was 2 treatments in Phase-III trials, in 2024 there are 3 (growth of 50%).
In 2023 there were 17 treatments in Phase-II trials, in 2024 there are 19 (growth of 11%).
In 2023 there were 14 treatments in Phase-IIΔ trials, in 2024 there are 19 (growth of 36%).
In 2023 there were 25 treatments in Phase-I trials, in 2024 there are 21 (dropped by 16%).

I think that the drop in Phase-I trials was mostly caused by me doing a good housecleaning to remove old, moribund trials, when I had not done that in several previous years.

A Little Discussion
 
The money that we donate does many things:
  1. It finances more clinical trials (especially early clinical trials).
  2. It finances making clinical trials (especially early clinical trials) larger and better designed.
  3. It helps push possible cures to the next level of trial.  It finances moving phase-I trials to phase-II, and phase-II to phase III.
I like to say that there are two reasons for donating money for research into T1D.  People who like the research being done should donate money to move it forward, faster.  People who don't like the research being done should donate money to start up different research which (presumably) they will like more.  So no matter which group you are in, you should donate.  😀
  
Trial Populations
 
The list above uses the following marks to show the nature of the treatments, and if one treatment is being tested in different populations, then it will be listed more than once.
Honeymoon: Most trials are done on people within the first year of diagnosis.  All the studies listed above which are not Established, At Risk, or Prevention are in this Honeymoon category.
Established: One or more trials are open to people who have had type-1 diabetes for over a year. 
At Risk: 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.
If a trial is not marked, then it is for people in the honeymoon (first year) of T1D.

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.  
 
I also give credit if JDRF funds research indirectly, through another organization.  For example, JDRF funds nPOD, Immune Tolerance Network, and INNODA and so I give Breakthrough T1D credit for clinical trials based on their work.
 
How I Count Trials for This Comparison
  • I don't count trials where the Breakthrough T1D funded some basic research, but not the research which lead to a specific clinical trial.  I'm sure this under estimates JDRF's impact.  For example OPT101 is an anti CD154 drug.  JDRF has funded many studies on CD154, but not the particular research that is being tested here.  Similarly with Ixekizumab, JDRF has funded related research on that drug, but not the clinical trial or the research immediately leading to the clinical trial here.
  • 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. 
  • 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.
  • 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 only include intervention studies here, because those are the only type of study that the FDA will accept for the eventual approval of a new treatment. 
Research Not Listed Here

I sometimes get asked why some piece of research is not listed here, and so here are some of those answers:
  • VX-880 is a transplant study which requires life long immunosuppression.  Read here why I do not consider these to be cures.
  • Levicure's Combination Therapy has only been tested in a retrospective study, not an intervention based clinical trial.

Some Specific Notes:
  • Oral Insulin: This trial was a phase-III trial, meaning that it was large and designed to provide enough information so that, 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.
This is an update and extension to blog postings that I've made for the previous fifteen years.  Below is a link to last year's, but you can search for "JDRF Funding for a Cure" for the rest of them:
Please remember that my blog (and therefore this posting) covers research aimed at curing, delaying, 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 Breakthrough T1D 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.

Fenofibrate Is Unsuccessful In A Phase-IIΔ Trial In Honeymooners

Fenofibrate (also spelled Phenofibrate) is commonly prescribed for high cholesterol and high triglycerides. In 2017, it was the 70th most commonly prescribed medication in the United States with more than eleven million prescriptions.  However, it is not approved for use in children under 18. It is also sometimes prescribed for diabetic retinopathy (eye damage from long term diabetes), and (off label) for gout.

However, it also showed some promise in NOD mice (an animal model for T1D), and so one person took it "off label" when they were diagnosed with T1D as a 19 year old.  They did not need to inject insulin for years after that, a huge result.  Still later, some researchers started a Phase-IIΔ trial.  These are my previous blog posts on Fenofibrate:

I had high hopes for this research.  I try not to become emotionally attached to specific research, because it clouds my judgement and because most research fails.  However, having one person go years without having to inject insulin was so good, and so unusual, that I was hopeful.  Unfortunately, this research did not pan out.

Results From the Phase-IIΔ trial

Here is the conclusion from the result's abstract:
Contrary to the beneficial effects of fenofibrate found in preclinical studies, this longitudinal, randomized, placebo-controlled trial does not support the use of fenofibrate for preserving beta cell function in individuals with newly diagnosed type 1 diabetes.

Since my initial excitement was based on a person who did not need to inject insulin after taking Fenofibrate, it makes sense to look at the insulin use and compare the people who got the drug (in red below) with the people who got the placebo (in blue).  You'll notice that the people who got the drug used a little more insulin.  This is the exact opposite of success, although the difference was not statistically significant.  Bottom line: it did not work.



This study used the same dose (160mg/day) that the successful "off label" used.  And that person stopped taking insulin after 19 days, so this study lasted much longer than needed to see the effect.  Also, the "off label" use started 7 days after T1D diagnosis, while this study started, on average, 22 or 24 days after diagnosis, with a standard deviation of 10 or 11 days.  The number of people who were "in remission" of T1D during their honeymoon was higher in the placebo group than in the treated group.  I put "in remission" in quotes because it is not what most people would consider remission.  They still used a little insulin, just not very much.  The researchers used a formal, technical definition of remission called the ADDRESS-2 definition, which is quite different than what you or I would call remission.
