Exsulin: New Phase-I Research Almost Ready to Start (for Non-Honeymoon Type-1 Diabetes)

The Exsulin company is hoping to start Phase-I human trials in June 2009 (so right soon now). They are testing a new formulation of INGAP called Exsulin, a drug designed to regrow beta cells in the pancreas.

Their Phase-I clinical trial is small, short, and open to people who have had type-1 diabetes for more than 2 years, so we should have some results soon. It is a three group design. One group gets nothing, one gets a full dose, the other gets a half dose. They are checking for all the right stuff: C-peptide, fasting glucagon, fasting glucose, total daily insulin dose, and HbA1c. They are using two sites Montreal and Rochester.

This is described on their web site:
http://www.exsulin.com/underway.html

INGAP (now renamed Exsulin) has a 12 year history of research. NOD mice trials worked well, but human trials didn't show much success (sound familiar?) The phase-I study is described here: http://www.clinicaltrials.gov/ct2/show/NCT00034255. The phase-II study is described here: http://www.clinicaltrials.gov/ct2/show/NCT00071409. It was funded by Proctor and Gamble but the results were not good enough to move forward.

The original developers of INGAP got back rights to it after P&G didn't like the phase-II results. Their analysis of the results convinced them that INGAP was helping grow new beta cells, but that those new cells were being killed off too quickly to help the patient. (Maybe because of the body's immune system, or maybe because of inflammation, or maybe for some other reason.) So it is natural for them to pair Exsulin with another drug to treat the other problem, and see if both together can cure type-1 diabetes. But the research they are starting now is just Exsulin, not paired with anything.

DiaKine starts Phase-I clinical trials on Lisofylline (LSF)

DiaKine is about to start it's first clinical trial in a research program aimed at curing type-1 diabetes. Their treatment is Lisofylline (LSF), an anti-inflammatory drug that (in NOD mice) has prevented type-1 diabetes and (when given with exendin-4) cured existing type-1 diabetes.

Previously (in May 2008) DiaKine has formed a joint project with Kinexum Metabolics, to run a human trial (phase-II) using both of their drugs together (LSF and INGAP). The combination had already given good results in NOD mice. That trial was supposed to start in "late 2008". Kinexum Metabolics has since changed it's name to Exsulin (not INsulin, but EXsulin. Get it?) I can't find any record of the LSF+INGAP trial starting, but each company is testing it's own stuff seperately, so maybe after that, they'll test them together. I know a lot of people are interested in an anti-inflammatory and a beta-cell growing combination therapy, and obviously these two companies are interested in that, also. In any case, this trial is LSF only, not the combo they talked about earlier.

The current trial involves 8 people, and is supposed to start in May 2009 and be done by December 2009.

This research is being done in New Jersey.

And the official press release is here (and is better than most):

The press release talking about LSF+INGAP together is here:

I want to thank the Wainscoat family for bringing this to my attention.

This blog discusses cures and preventatives for type-1 diabetes that are either in human trials or just about to start. Treatments for diabetes are not generally discussed here, unless they can turn into a cure or a preventative. My definition of a cure is this:
1. Blood sugar control without testing and with doctor's visits 4 times a year, or less. Any cure must result in an average lifespan close to normal.
2. Does not require a lifetime of immunsuppressive drugs, so it is not trading one treatment for another. (but a couple of operations, or a short course of drugs is OK)
Obviously, this is my personal definition of a cure; yours may differ.
Because a cure for type-1 diabetes is likely to involve a combination of several different drugs or treatments, I try to follow research into anything which may be an important part of the cure.

My Non-Conflict of Interest Statement

For the first 10 years of running this blog, I did not work for a company doing medical research. In 2018, I started working for Bigfoot Biomedical, which is developing an "automated insulin dosing/delivery solution" (what many call an Artificial Pancreas).
I blog on research aimed at curing type-1 diabetes, and I view Bigfoot Biomedical's work as treating type-1 diabetes (not a cure at all). Therefore, I don't view this work as conflicting with my blogging. However, if you consider the kind of automated insulin dosing/delivery solution that Bigfoot is developing to be an actual cure for type-1, then this would conflict with my blogging. I think they are quite different.
I don't get paid in any way by any company working on a cure for type-1 diabetes; I never have. And that includes free samples, free travel, or free anything. I do sometimes participate in market research studies or focus groups, and they sometimes pay.
None of the hours that I have put into my blog, or the posts that I make to any web site, has ever been paid for. (Except for some very nice and heart felt thank-you emails, and those are worth more than money.)
My daughter has type-1 diabetes and participates in clinical trials. I sometimes report on trials that she participates in, but I do not reveal her participation because I consider her medical history to be private.
I sometimes "beta test" new software or devices involved in type-1 diabetes. When I'm blogging about something where I have been given special access, I say so.
In the past I have volunteered with JDRF and The NIIB Project. I currently am a fellow with JDCA. The JDRF and NIIB work was completely unpaid. JDCA has given me equipment that I use to help my blogging, and on one occasion paid for specific consulting work.
