Possible Cures for Type-1 in the News (November)

Merck Cancels "Smart Insulin" (MK-2640) After Unsuccessful Phase-I Trial

This is the news everyone hoped we would not get.  After completing a phase-I trial of "Smart Insulin" (also known as MK-2640), Merck has decided not to move forward with it.  They have not published the results, but have published this: "MK-2640 was discontinued due to lack of efficacy".

News report:


This was the first (and so far only) glucose responsive insulin to be tested in humans.  However, there are several "smart insulins" being tested in animals, not to mention "smart artificial cells" and "smart membrane" based technologies, all aimed at automatically regulating the amount of insulin in the blood stream.  I expect some of these to enter human trials in the next few years.  So "smart insulin" may yet be a trail blazer, even if it itself was unsuccessful.

If results from this study are ever published, I'll blog on them here.  However, there is nothing forcing Merck to publish these results if they don't want to.

Phase-II T-Rex Trial Update

Caladrius Biosciences recently announced that they had enrolled the 70th patient (out of 111) in their clinical trial of CLBS03 for T1D.  So it has taken them roughly 18 months to recruit 2/3 of the patients they need.  If they can keep up that pace, they will finish recruiting in the third quarter of 2018, and finish collecting data in the third quarter of 2019, and publish in 2020.

A quick summary of this treatment is as follows: remove one specific type of T regulator cell (called "CD4(+)CD25(+)CD127(lo)") from a person with type-1 diabetes.  Grow them out so you have about 500 times more, and then put them back in the same person.  Since regulatory T cells naturally regulate the body's immune system, and the patient now has more of them, the hope is that they will prevent the autoimmune attack which causes type-1 diabetes.

They are recruiting patients in about 15 locations all over the US, so read the clinical trial registry to get a complete list and some contact information.

Clinical Trial Registry:

SIMPONI (Golimumab) Starts A Phase-I Trial In Pre-Symptomatics

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.  This is the second trial underway for this drug.  (The other one is called T1GER, and is for honeymooners.)  Simponi has already been approved to treat rheumatoid arthritis, psoriatic arthritis, ulcerative colitis, and ankylosing spondylitis.

This study is recruiting people who have two autoimmune antibodies (but no other symptoms of type-1 diabetes). They are recruiting 30 kids (aged 6-21), and will follow them for 17 months. Each kid will get 26 weekly injections.  Half the patients will get Simponi and the other half will get a placebo.  They hope to finish this study in mid 2021.

This study is current recruiting in Linkoping University Hospital, Linkoping, Sweden, SE 58185.
Study contact: 844-434-4210
They hope to start recruiting at other locations in Sweden and Finland soon.

The unusual thing about this trial is that they will not measure any effectiveness data at all.  The only data gathered will be safety and side effect data.  No C-peptide data, no A1c, or insulin usage.  That's very unusual for a type-1 diabetes study.  In my experience, even the phase-I studies gather some effectiveness data.

My daughter 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.

I remember that research on a type of bound insulin whose binding material would be liberated only by hyperglycemia, so it would amount to a self-regulating insulin dose, began in Italy and Bordeaux, France, in 1984. I actually wrote to the researchers in Bordeaux, and they seemed quite optimistic about how fast their product could be developed. And now here we are, a third of a century later, and still nothing.

Oscar, unfortunately the industry says who can or can not be cured. We r so fucked!

The only symptom that I had was tingling in my legs especially at night after I retired to bed. The tingling became more severe where I could not get them to stop. I thought I had restless leg syndrome. My doctor tested me for diabetes and found that I had type II diabetes and the sugar was attacking my legs because it had no place to go. He put me on a sugar free diet and Actos and within one to two days my symptom were gone.. One day I got extremely sick, could not keep anything down, had blurry vision, a rapid heartbeat.I Started taking metformin 1000 mg twice daily. I am writing this to inform others that nothing was really working to help my condition.I went off the metformin (with the doctor’s knowledge) and started on Diabetes herbal formula i ordered from Health Herbal Clinic, my symptoms totally declined over a 7 weeks use of the Diabetes natural herbal formula. i am now doing very well, Visit there website www. healthherbalclinic. net or email Info@ healthherbalclinic. net This treatment is incredible!
