A Clinical Study to Evaluate the Safety, Tolerability, PK, PD, and Efficacy of KBP-089 in Patients With T2DM

A Double-blind, Placebo-controlled, Randomised, Multiple-ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of KBP-089 in Patients With Type II Diabetes

KeyBioscience is developing KBP-089, a dual activator of both the amylin and calcitonin receptors, for the treatment of type II diabetes mellitus, using a subcutaneous injectable mode of administration.

This is a double-blind, placebo-controlled, randomised, multiple-ascending dose phase I trial to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and efficacy of KBP-089 in patients with type 2 diabetes, who are on stable therapy with metformin.

Subjects will receive daily subcutaneous injections in the abdomen over a period of 28 days. The planned maximum doses of KBP-089 to be investigated in the trial are 20 µg in cohort 1, 60 µg in cohort 2, and 150 µg in cohort 3. For cohort 1, the dose is planned to be escalated every 7 ±1 days, and for cohort 2 and cohort 3, every 3 days. Doses may be modified according to individual tolerability, but the dose regimen will not exceed 28 days.

The IMP is administered by daily subcutaneous injections taken in the morning before breakfast.

The trial is performed in Germany and at least 36 patients will be enrolled in the trial. The trial will be randomised 1:1:1 between maximum doses of KBP-089 of 20 µg, 60 µg, 150 µg and placebo. Within each of the three cohorts, 12 patients will be randomised 3:1 to KBP-089 and placebo.

• Medically unable or unwilling to discontinue current anti-diabetic therapy with DPP-4 inhibitor or sulfonylurea for at least 14 days prior to admission to the research facility (Day -2) and remain off medication until the follow-up visit. Patients taking metformin therapy at entry will continue their metformin at the usual individual dose throughout the trial.
• Have had a significant change in weight, defined as a gain or loss of at least 5% body weight in the 3 months prior to screening.
• A positive result in the alcohol and/or urine drug screen at the screening visit.
• Positive to the screening test for Hepatitis Bs antigen (HBsAg) or Hepatitis C antibodies and/or a positive result to the test for human immunodeficiency virus (HIV)-1/2 antibodies or HIV-1 antigen.
• Have had a blood transfusion or severe blood loss within the past 6 months or have known hemoglobinopathy, hemolytic anemia, sickle cell anemia, or have a hemoglobin value <11 g/dL (males) or <10 g/dL (females), or any other condition known to interfere with HbA1c methodology.
• Blood donation or blood loss of more than 500 mL within the last 3 months or any blood donation within the last month prior to screening.
