JDRF Funding for a Cure 2023

In the US, we are in the "Walking Season" when JDRF (Juvenile Diabetes Research Foundation) asks us to walk to raise money for a cure for type-1 diabetes. 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 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 JDRF.  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 JDRF has funded, and those JDRF has never funded.  
 
As a reminder, last year I changed the way I counted treatments in two ways: First, treatments which are subsets of other treatments are counted only once.  For example, if drug X is being tested, and there is a separate test of a combination of X and Y, these are only counted once.  If a third test is testing  X, Y, and Z, then it is still only counted once.  Second, treatments being tested in two different phases of the disease (such as honeymoon and established) are only counted once.
 
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 about 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!

Summary: there is 1 drug approved by the US FDA to delay the onset of T1D symptoms, and it was funded by JDRF:

This is big news!  It is the first drug approved which changes the course of T1D, rather than just treating the symptoms, like insulin.  I'm looking forward to reporting its progress to see how usage expands moving forward.

In Process of FDA Approval

Nothing is in process of approval right now.

Summary of all Trials
59 in total
39 funded by JDRF
So 66% 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
 
Of these treatments 12 (20%) are being tested on people with established T1D, of those, 9 are funded by JDRF.  So 75% of the trials recruiting people with established T1D are funded by JDRF.

Compared to Last Year
In 2022 there were 53 treatments in clinical trials, in 2023 there are 59 (growth of 11%).
In 2023, one treatment was approved by the FDA!
In 2022 there was 2 treatments in Phase-III trials, in 2023 there are 3 (growth of 50%).
In 2022 there were 16 treatments in Phase-II trials, in 2023 there are 17 (growth of 6%).
In 2022 there were 13 treatments in Phase-IIΔ trials, in 2023 there are 14 (growth of 7%).
In 2022 there were 22 treatments in Phase-I trials, in 2023 there are 25 (growth of 14%).

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 both nPOD and Immune Tolerance Network and so I give JDRF credit for clinical trials based on their work.
 
How I Count Trials for This Comparison
  • I don't count trials where the JDRF 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. 
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 fourteen years:
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 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.

My kid has type-1 diabetes and participates in clinical trials, which might be discussed here. My blog contains a more complete non-conflict of interest statement. Thanks to everyone who helps with the blog.
