TIXIMED Starts a Phase 1 Study of TIX100

TIX100 is a protein which inhibits the action of TIXNP (thioredoxin-interacting protein).  It is being developed by the TIXIMED company.  TXNIP is elevated in pancreatic islets of people with type-1 diabetes and causes beta cell death and dysfunction.  The hope is that inhibiting that protein will protect beta cells and therefore delay or prevent T1D.

Anath Shalev, a researcher at the University of Alabama, Birmingham is leading this research effort, first at UAB and now also at TIXIMED.  She first identified TXNIP in 2002 in human islets exposed to high glucose and then later showed that it played a role in glucose toxicity and diabetic beta cell loss.  Research has shown that inhibiting TXNIP protects beta cells and promotes beta cell health and function.

Recently she has run clinical trials for Verapamil, which lowers TXNIP and is already approved in the USA for the treatment of high blood pressure, migraines, and heart problems.  I have blogged several times on those studies, but especially the results from a phase-II trial here:

https://cureresearch4type1diabetes.blogspot.com/2023/03/results-from-phase-ii-verapamil-study.html

I also listed it as a drug to watch in 2024:

https://cureresearch4type1diabetes.blogspot.com/2024/01/what-to-watch-in-2024.html

because there is another phase-II study ongoing in Europe, but it is now scheduled to finish in 2025 or 2026.

TIX100 is an oral medicine, and a "small molecule", but I have not found any other public information on what it actually is.  It has been tested in animals for T1D, T2D, nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH).  For example: 
https://diabetesjournals.org/diabetes/article/72/Supplement_1/97-OR/150782/97-OR-Antidiabetic-TIX100-Improves-NAFLD-NASH-in

This Study

This is a blinded dosing study done in healthy people.  They are recruiting 35 people, none of whom have T1D, and giving them 6 different doses ranging from none to 200 mg of TIX100.   The goal is to make sure all potential doses are safe.  

This is a single dose study, follow up is after one week, and they expect to be done by May.  Because the end points are all safety and side effect related, we will not know anything about efficiency (if it actually works against T1D), but "the trip of 1000 miles starts with a single step".  Good results here will presumably enable an efficiency focused phase-II study.

The good things about this study are that it is quick and easy to participate in.  They are recruiting in one location:

Combination of Harmine and GLP-1RA Completes Phase-I Clinical Trial (In Healthy People)

This is the most fun I have had writing a blog in a long time.  It is not often I can blog about psychedelics and curing type-1 diabetes at the same time!  I hope it is as fun for you to read as it is for me to write.  Do not skip the "Discussion" section.

These researchers are testing Harmine as part of a long term project, which started by doing a quick screen of many chemicals, which identified Harmine as a possible way to help the body grow more beta cells.  This screening process involved cell cultures (i.e. biology not computer simulation). They then tested it in mice, and found strong beta cell growth.  They cured the mice of diabetes, but those mice did not have autoimmune diabetes.  Their pancreases were destroyed with a toxin to give them diabetes.  A different research group cured mice who were overfed into diabetes. These are both positive results, but neither involved autoimmune diabetes.

You can read about the mice research here:

https://www.science.org/doi/10.1126/scitranslmed.adg3456

https://pubmed.ncbi.nlm.nih.gov/37629550/

This blog reports on their first test in people, but they did not have T1D.  The researchers hope to move on to people with T1D in the future.

  

The Study

This study is unusual in that it enrolled people without T1D ("healthy people", in medical terminology) and only looked for bad side effects ("adverse effects") in the medicine and not effectiveness.  Almost all T1D studies that I've blogged about over more than 10 years, even the earliest phase-I trials enroll people with T1D and have end points that cover both safety and effectiveness.  But not this study.

This is an open-label, no control group, dose escalation study which enrolled 27 people.   Each person goes through the following doses: 100 mg, 200 mg, 300 mg, 500 mg, 700 mg, 900 mg and 1200 mg, stopping when they experience side effects.  The researchers are trying to find the largest does that has minimal side effects.

The results are summarized like this:  Harmine HCl can be orally administered to healthy participants in doses <2.7 mg/kg with minimal or no adverse effects. Doses >2.7 mg/kg are associated with vomiting, drowsiness, and limited psychoactivity.   So a 50kg person (110 lb.) can have a dose of 135 mg with minimal adverse effects, and a 91kg / 200 lb. person can go up to 270 mg.

This is good news, because it opens the way for clinical trials on people who have T1D, and tells the researchers what is the maximum dose they can use without bad side effects.

Discussion

Dose Comparison to Mice Work

The important finding of this clinical trial is that doses less than 2.7 mg/kg are safe and well tolerated.  ("well tolerated" being medical jargon for "In our judgement, the side effects of this treatment are small enough so that people would be willing to get them in order to also get the benefits of the treatment".)  For comparison, two previous research projects targeted curing T2D in mice with 30 mg/kg and targeted T1D mice with 3 mg/kg.  Together, this trial in people with T1D and the previous trial in mice suggests that the 3 mg/kg is a "sweet spot" dose: high enough to work and low enough to avoid bad side effects.

However, there was another difference.  People in this study were given Harmine in a single pill, but the previous mice study gave Harmine using a subcutaneous pump (like an insulin pump) and continually dosed throughout the day.  For comparison, the T2D mice were given 30 mg/kg daily with an injection.  So if we compare the people to the T1D mice, they got a similar dose, but the people got it once in a pill and the mice got it infused daily for months.  Since pills are generally easier to take than injections, this is good news, if pills are as effective as injections.

Obviously, an important target of future research is going to be if pills are an effective way of delivering this medicine, or if a continuously dosing pump is required.

Psychedelics

Harmine is found in several species of plants (esp. wild Rue) and animals (esp. butterflies), but it is famous as a component of Ayahuasca, a South American psychoactive folk medicine and religious sacrament.

It is being tested for psychiatric uses (suicide prevention, treating depression, PTSD, etc.) in several clinical trials, some of which have completed and some of which are ongoing.  

My favorite quote is from one of the researchers: 

no psychoactive properties have been identified in animal studies at the doses we are employing, but animals can’t tell you if they’re hallucinating

Obviously, this is why they are carefully doing a phase-I trial on healthy humans, looking specifically for psychedelic adverse effects.  I suspect it is also the reason the study was done at the Depression and Anxiety Center at Mount Sinai Hospital in New York city.  They have more experience with this kind of clinical trial.

I'm sure the association of Harmine with Ayahuasca is going to cause some regulatory complications, even after this study shows that it is not psychoactive at the doses they are giving.  The American DEA has a long history of aggressively opposing any potential medical use associated with psychoactive drugs.

What Next?

In my mind, the obvious next step is to run a phase-I or phase-II trial on people who actually have T1D, but that is not the direction these researchers are going in.  As described below they are looking for a patentable drug (which they hope will be even more effective).

And then there is the issue of bringing these discoveries to people with diabetes. Because harmine is a natural product, it can’t be patented. “If you can’t patent it, no drug company is going to make it because clinical trials are expensive,” he notes.

So, going forward, the team has turned its efforts toward other new small molecule compounds they have designed and synthesized, along with computer modeling. “Some of these are as good as harmine, and several are substantially better. Mount Sinai has patented these, and we’re now working to move them along via Mount Sinai’s Innovation Partners Program,” Dr. Stewart says.

Denosumab Starts A Phase-I Trial In People With Established T1D

Denosumab is a monoclonal antibody, which is already approved for several bone related diseases and is sold under the names Wyost, Xgeva, Prolia, and Jubbonti.  A research team has found that the pathway that Denosumab targets also has effects on beta cells. Animal studies suggest that Denosumab may protect and/or increase the number of beta cells and improve how well they work.  It was first approved in 2010 after being developed by Amgen.  There is a biosimilar available from Sandoz.

Denosumab is a subcutaneous (under the skin) injection, much like insulin.  It is taken every month or every six months, depending on the bone disease being treated.

This Study

This is a phase-I trial in 45 adults who have had T1D for between 1 and 5 years. It is blinded, randomized and has a control group.  People will get one injection every 3 months for one year.

There are two primary end points.  For safety, they will track adverse events and for effectiveness they will measure C-Peptide levels. There are secondary end points for more C-Peptide measures and also for A1c measurements.  There are tertiary end points for time-in-range and insulin sensitivity.

The trial started in September 2024 and should run until April 2026.

Discussion

This study is being done on people with established T1D, not honeymooners.  However, I'm not sure why.  The researchers state specifically that "Lab studies suggest that Denosumab may protect and/or increase the number of beta cells and improve how well they work."  For me, that suggests that this treatment would work much better during the honeymoon, when people with T1D still have some beta cells that work.  It is a mystery to me why they chose established T1Ds rather than honeymooners.

One large population based study, done in Taiwan, showed that people using Denosumab for Osteoporosis had a significantly smaller chance of being diagnosed with type-2 diabetes, than those who where not taking the drug.  That is an interesting finding, but those people all had plenty of working beta cells, so it is not clear to me that this finding is useful for people with established type-1 diabetes.  That study is published here: https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2814873

If this treatment is found effective, it could be used off label immediately, without FDA approval, since it is already approved for a different disease.

What To Watch In 2025

Last year, at the start of the year, I published a blog of four research projects I was looking forward to updates in the new year.  This year, I'm doing the same thing.  I'm also including an update of the project from last year.

What I'm Watching In 2025

Vertex VX-264 is an encapsulated beta cell transplant that does not require immune suppression.  The trial is expected to run until 2026, but the company has said that they expect to have some data to report in 2025.  I hope so!

https://www.clinicaltrials.gov/study/NCT05791201

https://investors.vrtx.com/news-releases/news-release-details/vertex-reports-third-quarter-2024-financial-results

VCTX211 is another encapsulated beta cell transplant that does not require immune suppression.

Biomea BMF-219 is a drug that the company hopes is "a brake on beta-cell turnover and growth, supporting the notion that [it] could lead to the regeneration of normal, healthy beta cells".  It is in the middle of a clinical trial which started in 2023 and is expected to finish in Sept-2025.  I'm looking forward to data in 2025.  I previously blogged on it here:

https://cureresearch4type1diabetes.blogspot.com/2024/06/bmf-219-starts-phase-ii.html

https://clinicaltrials.gov/study/NCT06152042

Ladarixin is a drug being developed by Dompé. It inhibits activity on parts of the immune system called the IL-8 receptor (which has two subtypes: IL-8a and IL-8b).  Dompé hopes that this will stop the progression of type-1 diabetes.  Ladarixin is in the middle of a phase-III trial, and they expect results in 2025.  This is a big study.  They have enrolled 327 people and 2/3s of them will get the treatment; with only 1/3 controls who get the placebo.

https://cureresearch4type1diabetes.blogspot.com/2023/05/dompe-starts-gladiator-phase-iii.html

Siplizumab is a monoclonal antibody targeting CD2, which is part of the immune system.  This study finished recruiting in Oct-2024, so I would expect results in late 2025.  I blogged on this here:

https://cureresearch4type1diabetes.blogspot.com/2024/04/siplizumab-starts-two-trials-in.html

https://clinicaltrials.gov/study/NCT06025110

Sana UP421 is a last minute addition.  It is a no-immunosuppression beta cell transplant.  In early January, they announced very positive 1 month data from 1 person.  They are currently running a 2 person study (so really tiny pilot study).  I'm not sure if they will have final data in 2025 or not, but if they continue to publish early data, I'll be following.

https://ir.sana.com/news-releases/news-release-details/sana-biotechnology-announces-positive-clinical-results-type-1

https://www.clinicaltrials.gov/study/NCT06239636

What I Watched In 2024

The quick summary of 2024, is that, of the four research projects I focused on:

    1. Semaglutide is big in T2D/Obesity, but did not make progress as a T1D cure.

    2. Ladarixin progressed as expected, but the real news is expected in 2025.

    3. Verapamil completed enrollment in 2024, so should have results by 2025, but has already led 

        to important follow-on work.

    4. Diamyd was hoping for full enrollment, but did not make that milestone.

So overall, I would say 1 project did better than expected, 1 project did as expected, and 2 projects did worse.  

Semaglutide (sold as: Ozempic, Wegovy and Rybelsus) had very strong results in a very small study of honeymoon T1Ds:

https://cureresearch4type1diabetes.blogspot.com/2023/09/strong-results-from-pilot-study-of.html

I was hoping to read about more research starting up in 2024 to confirm these results.  Because Semaglutide is widely used to treat T2D and for weight loss, I think just one or two confirmation studies will be required to enable widespread use.  If that gets us a year or two delay starting injections for newly onset T1D, that would be a huge win (and even more so if it could be combined with Teplizumab or other treatments).

Unfortunately, none of that happened.  Semaglutide continues to blow up (in a good way) for T2D/Obesity, but does not move forward for T1D.

Ladarixin is a drug being developed by Dompé.  I'm not sure why I put it in the 2024 list, because there was no expectation of results until the end of 2025.  Nothing happened, but it is on my 2025 list.

https://cureresearch4type1diabetes.blogspot.com/2023/05/dompe-starts-gladiator-phase-iii.html

Verapamil is another interesting "off label" drug.  This is a drug which is already approved (since 1981) and widely used (3 million prescriptions a year) for high blood pressure.  It is being tested on honeymooners.  Therefore, if clinical trials show that it helps, it should be available quickly, especially for aggressive doctors who are willing to prescribe it off label.

Unfortunately, the ongoing study which was going to finish in 2024 is now going to finish in either 2025 or 2026, so we'll be waiting longer for results.  I blogged about the start of this study here:

https://cureresearch4type1diabetes.blogspot.com/2022/02/verapamil-sr-starts-phase-ii-trial-ver.html

However this line of research has already led to the creation of the company TIXIMED working to start clinical trials on their drug TIX100, which is sort of a follow on to Verapamil.  They have gotten FDA approval for the clinical trial, but have not yet started it.

Diamyd is another drug in phase-III trials.  They hope to finish in 2025, but the news I was hoping for was that their clinical trial was fully enrolled in 2024.  Unfortunately, it looks like that did not happen.  The trial is still not fully enrolled, so I would not expect results in 2025.

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:

• https://cureresearch4type1diabetes.blogspot.com/2023/11/jdrf-funding-for-cure-2023.html

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:

https://cureresearch4type1diabetes.blogspot.com/search?q=Fenofibrate&by-date=true

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.

Journal Article: https://www.researchgate.net/publication/385385677_Effect_of_fenofibrate_on_residual_beta_cell_function_in_adults_and_adolescents_with_newly_diagnosed_type_1_diabetes_a_randomised_clinical_trial/link/6722f02decbbde716b4c5777/download

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.

Encellin Starts a Phase-I Trial of ENC-201-CED (Encapsulated Beta Cells)

The company Encellin has started a Phase-I clinical trial to test ENC-201-CED an encapsulated beta cell product.

Encapsulated Beta Cells In General

Encapsulated beta cells are implanted devices.  The encapsulation allows blood sugar in, and insulin out, but does not allow the body's immune system to attack the beta cells. It also allows nutrients in and waste products out. This allows the beta cells to naturally grow and to react to the body's sugar by generating insulin which goes into the body's blood system. Meanwhile, the body's autoimmune attack cannot target these beta cells, and you don't need to take any immunosuppressive drugs (as you would for a normal beta cell transplantation).  The cells inside the encapsulation can come from different sources, depending on the company creating the product.

Encapsulated beta cells seem like a straight forward cure for type-1 diabetes, but companies have been working on them since the 1990s, without creating a cure.  There appear to be several difficult problems to solve, especially getting oxygen to the new cells.   Bottom line is this: while encapsulated beta cells sound like a "just needs engineering" cure for type-1 diabetes, decades of work has not led to a cure yet, so it is obviously harder than it looks.

I have blogged at least 10 times over the last 15+ years on different encapsulated beta cell approaches:

This Study

This study will recruit 10 people between 18 and 70 years old.  Everyone will get the treatment.  There is no control group.  Everyone will be followed for about 4 months.  This is strictly a safety/tolerability test.  They are measuring adverse effects and how well the implant takes.  They are not measuring effectiveness.  Even in the secondary outcome measures there are no tests for A1c, Blood glucose, C-Peptide, or time in range.

The study started in March 2024 and they hope to finish in December 2025 and publish by July 2026.

Other than that, their clinical trial registry is very sparse, and I cannot find any information on the trial on the web site of the hospital which is actually running it.  Therefore, I don't know the exact requirements to participate in the study, how many operations are required, what sort of immune suppression is being used (if any), or how man encapsulated beta cells (or devices) will be implanted.

Discussion

I usually don't comment on company funding because I have found that it doesn't matter who funds research.  Sometimes big name companies fund failures and people I've never heard of fund successful research.  However, I will say that Encellin is mostly funded by Khosla Ventures, which is a big name in Silicon Valley venture capital.  Also, Encellin was incubated by Y-Combinator, which is a big name "factory" of Silicon Valley start ups.  These guys would be Silicon Valley royalty, if Silicon Valley had royalty.

History

About 7 years ago, there was a lot of excitement about research done at Tejal Desai's lab at UCSF.  Several people asked me about it and at least one person lobbied for me to write a blog on it.  There was widespread hope that this research would lead to a cure in a few years.  There was widespread belief that it would lead to clinical trials sooner than that.

I didn't blog on it because my policy is to wait until recruiting has started on a clinical trial (a test done on people).  Seven years ago, all we had was very optimistic press releases.  But now, finally, this clinical trial is the follow on to Tejal Desai's work all those years ago.  They have started a clinical trial on this technology and so I'm blogging on it.

Remember this when you are frustrated because some research that you heard very positive things about never seemed to go anywhere.  First, a lot of very positive sounding research never does go anywhere.  That is the normal nature of research.  Second, even when it does, it takes many years.  The successful out come still takes many years.
