Benefits of technology

"The present invention provides new methods for treating diabetes with insulin and glucagon that can reduce the risk of hypoglycemia. The pharmaceutical compositions can be administered through various routes such as injection, orally, transdermally, or by inhalation. The ratios between insulin and glucagon can be maintained simultaneously or within a few hours of each other. The methods involve co-administration of insulin and glucagon to a diabetic patient before the symptoms of hypoglycemia are present. The invention also provides new glucagon formulations and modified glucagon for co-administration with insulin. Kits for preventing hypoglycemia and restoring or preventing loss of hypoglycemic awareness or sensitivity are also provided."

Problems solved by technology

Endogenous insulin levels may be low or undetectable in some patients with diabetes mellitus.
In striving to achieve this goal, physicians have encountered a substantial increase in the frequency and severity of hypoglycemia in their diabetic patients.
Thus, efforts to achieve normal glucose levels with insulin can result in the development of hypoglycemia of varying frequency and severity in patients.
Hypoglycemia and the lack of awareness of its presence are serious complications of insulin therapy that occur with greater frequency and severity when impaired counter-regulatory (anti-insulin) responses are present in diabetic patients.

example 1

Co-Administration of Glucagon Parenterally and Insulin for the Control of Diabetes and Prevention of Hypoglycemia

[0112]The glucagon currently available in the North American market is human glucagon of rDNA origin produced either by Eli Lilly & Co or Bedford Labs (Novo). Four brand names are known: Glucagon Diagnostic Kit (Lilly); Glucagon Emergency Kit (Lilly); Glucagon Emergency Kit for Low Blood Sugar (Lilly); and GLUCAGEN (Bedford Labs).

[0113]Novo produces glucagon under its own name outside of North America. Novo produces its glucagon in yeast, and Lilly produces its glucagon in E. coli. The following examples illustrate practice of some of the methods using such commercially available glucagons and insulins administered via a variety of routes.

[0114]The Lilly glucagon is typically provided in kit form. The glucagon within the kit is in the form of a powder within a sterile vial with a standard rubber-sealed neck. The vial contains a mixture of 1 mg of lyophilized glucagon, 49 ...

Co-Administration of Glucagon by Pump and Insulin for the Control of Diabetes and Prevention of Hypoglycemia

[0142]In one method, insulin can be administered by pump. There are a number of pumps commercially available (or soon to be available) in the US market and elsewhere that are suitable for use in the present methods. These include but are not limited to:[0143]ANIMAS (IR-1000 & IR-1200)[0144]DELTEC (Cozmo pump)[0145]DISETRONIC (H-TRONplus and D-TRONplus)[0146]LIFESCAN & DEBIOTECH (MEMS Insulin Pump in development)[0147]MEDTRONIC MINIMED (PARADIGM Insulin Pump and 508 Insulin Pump)[0148]MEDTRONIC MINIMED (2007 Implantable Insulin Pump System (EU only))

[0149]When both the insulin and the glucagon are to be administered by pump (from separate reservoirs), a number of configurations can be employed in the practice of the present method. Typical configurations are:[0150](1) A single device with a single pump and two reservoirs (for dual reservoir pumps, see, for example, U.S. Pat. No...

Co-Administration of Glucagon and Insulin, Admixed, by Pump for the Control of Diabetes and Prevention of Hypoglycemia

[0178]Some embodiments of the methods of the invention can also be practiced using pump-based administration of an admixture of both insulin and glucagon. This method provides protection from hypoglycemia in direct proportion to the amount insulin used and with a built in delay. It also replaces basal levels of glucagon throughout the day and especially after meals, as it will also be administered with the basal insulin administered by the pump. This embodiment can be practiced using standard pumps currently available and described in Example 2. One difference is that the insulin cartridges used will contain a mixture of insulin and glucagon (optionally modified release glucagon), with the glucagon component being between 32-96 or 41-96 mU to be administered each hour of desired protection (prevention of hypoglycemia). In some embodiments, the amount of glucagon admi...
