A Study of Monthly Subcutaneous Continuous Erythropoietin Receptor Activator (CERA) in Predialysis Participants With Chronic Renal Anemia (ORION)

Last verified: March 2016
This single arm study will assess the long term maintenance of hemoglobin (Hb) levels, safety and tolerability of once monthly subcutaneous methoxy polyethylene glycol-epoetin beta (CERA) in predialysis participants with chronic renal anemia. Participants currently receiving subcutaneous darbopoetin alfa maintenance treatment will receive subcutaneous methoxy polyethylene glycol-epoetin beta for a maximum of 32 weeks at a starting dose of 120, 200 or 360 micrograms every 4 weeks according to the dose of darbopoetin alfa administered in Week -1. Subsequent doses will be adjusted to maintain hemoglobin levels within the target range of 10 to 12 grams per deciliter (g/dL).

Primary Purpose: Treatment
Official Title: A Single Arm, Open Label Study to Assess the Efficacy, Safety and Tolerability of Once Monthly Administration of Subcutaneous C.E.R.A. for the Maintenance of Haemoglobin Levels in Pre-Dialysis Patients With Chronic Renal Anaemia

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Percentage of Participants Maintaining Their Mean Hb Concentration Within Plus/Minus (±) 1 Grams Per Deciliter (g/dL) of the Reference Range and Between 10.0 and 12.0 g/dL During Efficacy Evaluation Period (EEP) [ Time Frame: EEP: Weeks 17 to 28 ]
    The reference Hb was defined as the average Hb concentration calculated on the basis of all Hb assessments taken at Weeks -4, -2, and 0 (before the first dose administration).

Secondary Outcome Measures:
  • Change in Hb Concentrations Between EEP and Stability Verification Period (SVP) [ Time Frame: SVP: Week -4 to Week 0; EEP: Weeks 17 to 28 ]
    Hb concentrations during SVP were the reference Hb concentrations. For each assessment period (SVP and EEP) the average Hb concentration was calculated on the basis of all Hb assessments taken during the assessment period. Change in average Hb concentration from reference range (SVP) was calculated.

  • Percentage of Participants Maintaining Hb Concentrations Within the Range of 10.0 to 12.0 g/dL Throughout EEP [ Time Frame: EEP: Weeks 17 to 28 ]
  • Median Time Spent in the Hb Range of 10.0 to 12.0 g/dL During the EEP [ Time Frame: EEP: Weeks 17 to 28 ]
  • Percentage of Participants Requiring Any Dose Adjustment During Dose Titration Period (DTP) and EEP [ Time Frame: DTP: Weeks 1 to 16; EEP: Weeks 17 to 28 ]
    The methoxy polyethylene glycol-epoetin beta dose adjustment (dose increase or decrease) was required: if a single Hb concentration was either greater than or equal to (≥) 13 g/dL or less than or equal to (≤) 9 g/dL; if the difference of 2 consecutive Hb concentrations was ≥2 g/dL; when the values of scheduled Hb assessments on the days of drug administration and on the previous study visit were both out of range of 10.5 to 11.5 g/dL and the difference between the reference value (average Hb concentration calculated on the basis of all Hb assessments taken at Weeks -4, -2, and 0) and the most recent value was >1 g/dL; and when the values of scheduled Hb assessments on the days of drug administration and on the previous study visit were both out of range of 10 to 12 g/dL. Dose adjustment could be made at any time at the discretion of the clinician if clinically warranted.

  • Percentage of Participants Who Required Red Blood Cell Transfusions [ Time Frame: Weeks 1 to 28 ]
