This study has been completed.
Sponsor:
Collaborator:
Cytokinetics
Information provided by (Responsible Party):
Amgen
ClinicalTrials.gov Identifier:
NCT01737866
First received: October 16, 2012
Last updated: August 9, 2013
Last verified: August 2013
  Purpose
A phase 1, open-label study in subjects with normal renal function and subjects with various degrees of renal insufficiency, including patients with end-stage renal disease (ESRD) requiring hemodialysis. The primary objective is to evaluate the single-dose PK of AMG 423 in subjects with various degrees of renal insufficiency, including patients with end-stage renal disease requiring hemodialysis.

Condition Intervention Phase
Heart Failure Drug: AMG 423 Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-label, Single-dose Study of the Safety, Tolerability, and Pharmacokinetics of AMG 423 in Healthy Subjects and Subjects With Various Degrees of Renal Insufficiency and Effect of Hemodialysis on AMG 423 Pharmacokinetics

Primary Outcome Measures:
  • AMG 423 Pharmacokinetic Parameters [ Time Frame: Twenty time points, up to eight days ]
    Part A and Part B: Total AMG 423 pharmacokinetic parameters including area under the plasma concentration time curve (AUC) from time 0 to the time of the last quantifiable sample (AUC0-t) and maximum observed plasma concentration after dosing (Cmax).


Secondary Outcome Measures:
  • Other Total AMG 423 PK Parameters [ Time Frame: Twenty time points, up to eight days ]
    Total AMG 423 pharmacokinetic parameters including but not limited to terminal phase half life (t1/2) and time of maximum AMG 423 plasma concentration (tmax), AUC from time 0 to infinity (AUCinf) and apparent plasma clearance (CL/F) for Part A and Part B;

  • AMG 423 Dialysis Clearance [ Time Frame: Hours 4, 5, 6, 7 & 8 post-dose ]
    AMG 423 dialysis clearance (CLd) for ESRD subjects in Part A;

  • AMG 423 Metabolites [ Time Frame: Twenty time points, up to eight days ]
    AMG 423 metabolites (M3 and M4) pharmacokinetic parameters including but not limited to AUC0-t, AUCinf, AUC metabolite to parent ratios, Cmax, tmax and t1/2, if appropriate.

  • Safety [ Time Frame: Up to 46 days, including a 28 day screening period ]
    Secondary safety endpoints are subject incidence of adverse events and clinically significant changes in vital signs, physical examinations, clinical laboratory tests and ECGs.

Criteria

Inclusion Criteria:

  • Men or women ≥18 years of age
  • Laboratory test values (clinical chemistry and hematology)within normal limits, (other than test values out of the normal range for subjects with CKD [groups 1 and 3 through 5]), or clinically acceptable to the investigator and sponsor at screening and day -3
  • Free of any clinically significant disease or condition(s) (other than that consistent with CKD for subjects in groups 1 and 3 through 5) that require a physician's care and/or would interfere with the evaluations, procedures, or participation in the study per the investigator's discretion;

Exclusion Criteria:

  • Subjects who have received a functioning renal transplant within the past year
  • Subjects with ESRD who do not have a functioning hemodialysis access
  • Subjects with hemodynamic instability during hemodialysis
  • Subjects whose renal insufficiency is due to active autoimmune renal disease
  • Subjects with renal insufficiency or ESRD requiring hemodialysis and Troponin I > upper limit of normal (ULN) at screening or day -3
  • Subjects with history of heart disease or unstable angina within the last 3 months
  • Subjects with uncontrolled diabetes (Hb1Ac > 8%) and/or subjects who are able but unwilling to adhere to the required fasting intervals
