Official Title: A Phase I, Open-label, Parallel-group, Mono-center Trial to Investigate the Pharmacokinetics of a Single Intravenous Dose of Cilengitide in Subjects With Mild, Moderate or Severe Renal Impairment Compared to Subjects With Normal Renal Function

Further study details as provided by Merck KGaA:

Primary Outcome Measures:
  • Peak Plasma Concentration (Cmax) of cilengitide in plasma [ Time Frame: 48 hours after start of infusion of 1 single dose of cilengitide administered as 1-hour intravenous infusion ] [ Designated as safety issue: No ]
    Cmax of cilengitide in plasma after single dose in groups of subjects with different grades of renal function compared to subjects with normal renal function.

  • Area under the plasma concentration versus time curve (AUC) of cilengitide in plasma [ Time Frame: 48 hours after start of infusion of 1 single dose of cilengitide administered as 1-hour intravenous infusion ] [ Designated as safety issue: No ]
    AUC of cilengitide in plasma after single dose in groups of subjects with different grades of renal function compared to subjects with normal renal function.


Secondary Outcome Measures:
  • Terminal half life t1/2 of cilengitide [ Time Frame: 48 hours after start of infusion of 1 single dose of cilengitide administered as 1-hour intravenous infusion ] [ Designated as safety issue: No ]
  • Plasma clearance of cilengitide (CL) [ Time Frame: 48 hours after start of infusion of 1 single dose of cilengitide administered as 1-hour intravenous infusion ] [ Designated as safety issue: No ]
  • Cilengitide volume of distribution (Vz) in plasma [ Time Frame: 48 hours after start of infusion of 1 single dose of cilengitide administered as 1-hour intravenous infusion ] [ Designated as safety issue: No ]
  • Absolute and relative amount of cilengitide excreted into urine (Ae0-∞) [ Time Frame: 24 hours after start of infusion of 1 single dose of cilengitide administered as 1-hour intravenous infusion ] [ Designated as safety issue: No ]
  • Renal clearance of cilengitide (CLR) [ Time Frame: 24 hours after start of infusion of 1 single dose of cilengitide administered as 1-hour intravenous infusion ] [ Designated as safety issue: No ]
  • Plasma-protein-binding: Fraction unbound of cilengitide [ Time Frame: 2 hours after start of infusion of 1 single dose of cilengitide administered as 1-hour intravenous infusion ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Group 1
Healthy volunteers: matched subjects with normal renal function
 Drug: cilengitide 2000mg
A single dose of cilengitide 2000mg (250mL) will be administered as 1-hour i.v. infusion on Day 1
Experimental: Group 2
Mild renal impaired subjects
 Drug: cilengitide 2000mg
A single dose of cilengitide 2000mg (250mL) will be administered as 1-hour i.v. infusion on Day 1
Experimental: Group 3
Moderate renal impaired subjects
 Drug: cilengitide 2000mg
A single dose of cilengitide 2000mg (250mL) will be administered as 1-hour i.v. infusion on Day 1
Experimental: Group 4a
First group of Severe renal impaired subjects
 Drug: cilengitide 1000mg
A single dose of cilengitide 1000mg (125mL) will be administered as 1-hour i.v. infusion on Day 1
Experimental: Group 4b
Second group of severe renal impaired subjects
 Drug: cilengitide > 1000mg and up to 2000mg
A single dose of cilengitide > 1000mg and up to 2000mg will be administered as 1-hour i.v. infusion on Day 1 if applicable, based on Safety Monitoring Committee decision

Detailed Description:

Subjects with impaired renal function will be screened and will be stratified by their estimated glomerular filtration rate (GFR) according to the Modification of Diet in Renal Disease (MDRD) equation and assigned to one of the stratification groups defined below:

Group Number/Renal function/Creatinine Clearance (GFR according to MDRD)

  1. Normal renal function (≥ 90 mL/min)
  2. Mild renal impairment (60 - 89 mL/min)
  3. Moderate renal impairment (30 - 59 mL/ min) 4a: Severe renal impairment (< 30 mL/min) - no dialysis required 4b: (if applicable) Severe renal impairment (< 30 mL/min) - no dialysis required

Subjects in Groups 2 and 3 will receive a single dose of 2000mg of cilengitide as 1-hour i.v. infusion. Subjects from group 4a will receive a single dose of 1000mg of cilengitide as 1-hour i.v. infusion . PK samples will be collected and basic PK parameters will be calculated. The safety, tolerability, and PK will be evaluated by the Safety Monitoring Committee (SMC). If the SMC has no concerns, Group 4b will be treated with a higher dose (up to 2000mg) of cilengitide. Then, Group 1 (healthy subjects) will be started after the last subject with renal impairment (in either Group 2, 3, or 4a; or in Group 4b, if applicable) has completed all activities on Day 3. They will also receive a single dose of 2000mg of cilengitide as 1-hour i.v. infusion.

The duration of the trial from the first subject enrolled to the last subject last visit will be approximately 6 months (approximately 8 months, in case Group 4b is included). Each subject will participate in the trial for up to 35 days, including screening and the end of trial examination.
