Type 1 diabetes mellitus (T1DM) is an autoimmune disease. Autoimmune diseases happen when
the immune system does not identify part of the body as belonging to it. The immune system
then destroys that part as if it were an unknown tissue in the body. In T1DM, the body kills
the cells in the pancreas that produce insulin. Insulin is the hormone that "unlocks" the
cells of the body. It allows glucose to enter and fuel them. Special cells in the body
called islets make the insulin. Since glucose cannot enter the cells, it builds up in the
blood. The body's cells literally starve to death. Children are at risk of developing T1DM
and the risk is much higher than other severe, chronic childhood diseases. The only
treatments are a careful diet, planned physical activity, and testing blood sugar levels
several times a day. The patient must also inject insulin each day or use an insulin pump.
There is no cure for T1DM. Insulin injections are considered life support, because going
without insulin for just a few days causes the blood to have too much acid in it and that
can lead to death. On the other hand, taking too much insulin makes blood sugar levels go
too low, and if untreated, can lead to death as well.
DiaKine is developing Lisofylline to treat the failed immune system. This is what caused
T1DM in the first place and it does not go away. The purpose of this study is to see how
safe the study drug is. The study is also going to compare the levels of study drug in the
blood and to measure the effect of the study drug on other substances in the blood that are
linked to type 1 diabetes. These levels will be measured after the study drug is given as an
injection under the skin and an injection into the vein. To date, Lisofylline has been
tested when given as an injection in the vein.
The investigators hypothesize that Lisofylline will be safe when given as an injection under
the skin and in the vein and that levels of study drug will be very similar when given as an
injection under the skin and in the vein.
The investigators also hypothesize that Lisofylline will have a positive effect on the
substances in the blood that are linked to type 1 diabetes.
