Condition(s) targeted: Type 1 Diabetes

Intervention: Intradermal injection (Procedure); Subcutaneous injection (Procedure)

Phase: Phase 2

Status: Active, not recruiting

Sponsored by: Massachusetts General Hospital

Steven J Russell, MD, PhD, Principal Investigator, Affiliation: Massachusetts General Hospital


The investigators are doing this research study to find out if the type of needle used to administer them affects the speed with which insulin and glucagon get into the blood. The investigators will compare a traditional insulin needle to an injection device, called the MicronJet, that uses microneedles to deliver medication into the top layer of your skin.

Clinical Details

Official title: Pharmacokinetic Comparison of Intradermal Versus Sub-cutaneous Insulin and Glucagon Delivery in Volunteers With Type 1 Diabetes

Study design: Allocation: Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Aggregate mean difference in tmax between the delivery methods (the insulin and glucagon data will be evaluated separately)

Secondary outcome:

Aggregate mean difference in t1/2max between the methods

Aggregate mean difference in Cmax between the methods

Aggregate mean difference in area under the curve (AUC) between methods

AUC of 0-1 hour (and by subtraction hours 1-5)

AUC of 0-2 hours (and by subtraction hours 2-5)

Time to 50% of Total AUC (or said another way, time to 50% exposure)

Fraction of subjects with difference in tmax between the methods of > 25%

Fraction of "dry" injections with no reflux of fluid from the injection site

Difference in mean visual analog pain score between the two methods

Difference in mean visual analog pain score between insulin and glucagon with subcutaneous injection

Difference in mean visual analog pain score between insulin and glucagon with intradermal injection


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
