A Study of Intravenous (iv) Mircera in Hemodialysis Patients With Chronic Renal Anemia
26 de octubre de 2016 actualizado por: Hoffmann-La Roche
An Open-label, Multicenter, Randomized Study to Determine Dose Conversion Factors at Different Frequencies of Administration After Switching From Maintenance Treatment With Intravenous Epoetin Alfa to Maintenance Treatment With Intravenous RO0503821 in Hemodialysis Patients With Chronic Renal Anemia.
This study will determine the appropriate dose and frequency of administration of iv Mircera maintenance therapy in hemodialysis patients with chronic renal anemia who were previously receiving iv epoetin.
The anticipated time on study treatment is 3-12 months and the target sample size is <100 individuals.

Median Change From Baseline in Hemoglobin Levels to End of Initial Treatment Under Constant Dosing Regimen
Periodo de tiempo: From Baseline (Day -28 to Day 1) to EOIT (Week 19)
|
Median change from Baseline in hemoglobin (Hb) levels to end of initial treatment (EOIT) under constant dosing regimen was reported.
For ease of interpretation, all individual slope values were multiplied by 42 to give an estimate of change in Hb values over six weeks.
Baseline (Day -28 to Day 1) Hb values was calculated as the mean of the screening assessment (SA) and run-in period (Week -2 and Week -1).
For all participants, an EOIT value was calculated as the last observed Hb value before a dose change or blood transfusion.
For participants without any dose adjustments or blood transfusion, the EOIT value was identical to the Week 19 value.

Median Change From Baseline in Hematocrit Levels to End of Initial Treatment Under Constant Dosing Regimen
Periodo de tiempo: From Baseline (Day -28 to Day 1) to EOIT (Week 19)
|
Median change from Baseline in hematocrit (Hct) levels to end of initial treatment under constant dosing regimen was reported.
Baseline (Day -28 to Day 1) Hct values was calculated as the mean of the SA and run-in period (Weeks -2 and -1).
For all participants, an EOIT value was calculated as the last observed Hct value before a dose change or blood transfusion.
For participants without any dose adjustments or blood transfusion, the EOIT value was identical to the Week 19 value.

Number of Participants With Any Adverse Events, Any Serious Adverse Events, And Deaths
Periodo de tiempo: Up to Week 126
|
An Adverse Events (AEs) is defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
Serious Adverse Events (SAEs) is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is a significant medical event in the investigator's judgment or requires intervention to prevent one or other of these outcomes.
).
The study design tested 3 different starting dose conversion factors at 3 different dosing schedules during the core study period.
As study drug doses can be modified continually over time all results for the two long term safety periods were displayed by dose schedule group only.

Up to Week 126

Number of Participants With Marked Laboratory Abnormalities
Periodo de tiempo: Up to Week 126
|
Marked abnormality was defined as above and/or below a value which was considered to be potentially clinically relevant.
The number of participants with marked lab abnormality across treatment groups were reported and presented.
Marked laboratory abnormalities were analyzed according to the Roche specified limits for the following reference range: White blood cells (WBC) (3.0- 18.0 10^9/L), Platelets (100 - 550 10^9/L), Alanine aminotransferase (ALAT) [0 110 units per litre (U/L)], Alkaline Phosphatase (ALP) (0 - 220 U/L), Aspartate aminotransferase (ASAT) (0 - 80 U/L), Albumin >= 30 g/L, Phosphate [0.75 - 1.60 millimoles per liter (mmol/L)], Potassium (2.9 - 5.8 mmol/L), Glucose (2.80 - 11.10 mmol/L).

Mean Change From Baseline in Systolic Blood Pressure and Diastolic Blood Pressure Before and After Dialysis
Periodo de tiempo: From Baseline (Day -28 to Day 1) to Week 126
|
Mean Change from Baseline in systolic blood pressure (SBP) and diastolic blood pressure (DBP) is calculated as the end of treatment values minus the Baseline value.
Baseline (Day -28 to Day 1) values were calculated as the mean of the screening assessment (SA) and run-in period (Week -2 and Week -1).

From Baseline (Day -28 to Day 1) to Week 126

Mean Change in Pulse Rate
Periodo de tiempo: Up to Week 126
|
Participants pulse rates in beats per minute (BpM) were analyzed at sitting position using descriptive statistical methods (ie, means, standard deviations and percentiles).
The changes in pulse rate throughout the study were analysed at each study visit and mean change is reported.
