简要总结

DM199 (recombinant human tissue kallikrein-1) is a new investigational compound that may eventually be used for the treatment of Diabetes Mellitus Type 2. This is the first time that this compound is being given to humans.

The purpose of the study is to investigate to what extent DM199 is safe and tolerated. Further, it will be investigated how quickly and to what extent DM99 is absorbed and eliminated from the body (this is called pharmacokinetics). In addition, the effect of the compound on the body will be investigated (this is called pharmacodynamics).

This study is not intended to improve anyone's health, but is necessary for the further development of DM199.

The study consists of 4 parts. Each part (A, B, C and D) will consist of one or several periods. The research will be conducted in healthy male and female volunteers (Part A and C) and in male and female type 2 diabetes mellitus patients (Part B and D).

详细描述

DM199 (recombinant human tissue kallikrein-1) is being developed as a new biological treatment for type 2 diabetes mellitus. This is a first-in-human study for DM199 and is a 4-part, single center study in healthy subjects and type 2 diabetes mellitus patients.

Part A will be a randomized, double-blinded, placebo-controlled, single ascending dose (SAD) study in healthy male and/or female subjects. Subjects will receive DM199 or placebo subcutaneously (sc).

Part B will be a randomized, partially double-blinded, placebo-controlled, sequential SAD study in male and/or female type 2 diabetes mellitus patients.

Part C will be a randomized, double-blinded, placebo-controlled, 14-day multiple ascending dose (MAD) study in healthy male and/or female subjects each. Subjects will receive sequential doses of DM-199 or placebo sc for 14 days.

Part D will be a randomized, double-blinded, placebo-controlled, 28-day multiple-dose proof of concept (POC) study in male and/or female type 2 diabetes mellitus patients. Subjects will receive parallel doses of DM199 or placebo sc for 28 days.

  • Medical history without clinically significant abnormalities
  • Parts B and D: Taking a stable dose of one or more oral anti-diabetic medications, such as metformin, sulphonylurea or any other orally administered glucose lowering medication (except for thiazolidinediones) for at least 3 months prior to screening. Receiving no other chronic medications, including dietary supplements, that alter blood glucose control.
  • Parts A and C: Resting supine blood pressure of 140/90 mmHg or lower and higher than 90/50mmHg at screening, and showing no clinically relevant deviations as judged by the Principal Investigator
  • Parts B and D: Resting supine blood pressure of 160/100 mmHg or lower and higher than 90/50mmHg at screening, and showing no clinically relevant deviations as judged by the Principal Investigator

排除标准

  • Evidence of clinically relevant pathology
  • Pregnancy or lactation
  • For healthy volunteers: use of concomitant medication, except for acetaminophen (paracetamol), which is allowed up to 3 days before entry into the clinical research center (after that time the use of a limited amount of acetaminophen is permitted after consultation with the Principal Investigator). Multivitamins and vitamin C are allowed up to 7 days before entry into the clinical research center. All other medication (including over the counter medication, health supplements, and herbal remedies such as St. John's Wort extract) must have been stopped at least 14 days prior to entry into the clinical research center.
  • Participation in a drug study within 60 days prior to drug administration. Participation in more than 3 other drug studies (for men) / more than 2 other drug studies (for women) in the 10 months preceding the start of this study)
