A Study of Efepoetin Alfa in Treating Anaemia Associated With Chronic Kidney Diseases Patient
- Conditions
- Anaemia Associated With Chronic Kidney Disease
- Interventions
- Registration Number
- NCT04155125
- Lead Sponsor
- PT Kalbe Genexine Biologics
- Brief Summary
This is an open-label, randomised, multicenter, Mircera-controlled, parallel-group, Phase III study to determine whether subcutaneous administered efepoetin alfa is as effective and well tolerated as subcutaneous Mircera for anaemia correction and maintenance in erythropoiesis stimulating agent (ESA)-naïve subjects who have CKD and are not on dialysis. ESA prior users who have stopped using ESA at least 12 weeks till screening will also be eligible for this study provided they fulfil all the subject entry criteria.
- Detailed Description
The study will consist of a 20-week correction period for dosage titration and Hb correction, followed by an 8-week evaluation period for efficacy assessments of corrective treatment. Subjects who respond to efepoetin alfa (defined as an increase in Hb ≥1.0 g/dL versus baseline and Hb level within 10 - 12 g/dL range without blood transfusion during the 28 weeks after the first dose) will be eligible to continue treatment, and will be randomised to receive subcutaneous efepoetin alfa either once every 2W or every 4W for an additional 24-week extension period to assess long-term safety and maintenance effect. Mircera responders will also be allowed to continue the drug during the extension period, receiving it every 4 weeks using the dose equal to twice the previous once-every-two-week dose. The safety data collected will be part of an ongoing pooled analysis of safety data from the efepoetin alfa clinical development program.

(Routinely screening for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infection is not required in this protocol. By history or current clinical evidence, patients with active acute HBV or HCV infection should be excluded. Chronic HBV/HCV infection with LFTs > 3 times of normal are excluded. Known HIV positive patients are excluded)

- Arm && Interventions
Group Intervention Description efepoetin alfa efepoetin alfa Route of administration: Subcutaneous Injection. The administration interval and initial dosage for subjects who are randomly assigned to subcutaneous efepoetin alfa will be starting from 4 μg/kg BW once per 2 weeks, then titrated based on Hb level during study period. Mircera Mircera Route of administration: Subcutaneous Injection. The starting dosage of Mircera arm will be 0.6 μg/kg BW per 2 weeks based on prior data in similar study populations with subsequent titration to achieve targeted Hb range. During the correction treatment period, the dosage of study drug will be adjusted to achieve a Hb level range within 10 - 12 g/dL and an increase ≥1.0 g/dL versus the individual patient's baseline Hb level. During the extension period, Hb levels should be maintained between 10 and 12 g/dL.
- Primary Outcome Measures
Name Time Method To assess the efficacy of efepoetin alfa in the treatment of anaemia associated with CKD as measured by haemoglobin (Hb) response rate at the end of correction treatment evaluation period Measurement from the date of Randomization till the End of the Corrective Treatment period, assessed up to 20 weeks. Measurement is done by an increase in Hb more than or equal to 1 g/dL compared with baseline and a Hb concentration within range of 10 - 12 g/dL inclusive without transfusion during evaluation period
- Secondary Outcome Measures
Name Time Method Characterise safety and tolerability of subcutaneous efepoetin alfa is being measured by based on the frequency of adverse events and on the number of out of range laboratory values. Measurement from the time the subject provides informed consent through and including 28 calendar days after the last study drug administration. Safety endpoints parameters including Serious Adverse Events (SAE) specified below
1. Composite outcome of cardiovascular death or a nonfatal myocardial infarction or stroke
2. All-cause mortality
3. Cardiovascular mortality
4. Acute myocardial infarction
5. Heart failure
6. Acute kidney injury defined according to Acute Kidney Injury Network (AKIN) criteria
7. Abnormal clinical laboratory tests (haematology, biochemistry including serum ferritin and TSAT)
8. Anti-efepoetin alfa or anti-Mircera antibody titres
9. Clinically meaningful abnormal findings of vital signs
10. Development of clinically meaningful electrocardiogram abnormalities
11. Hospitalisations (excluding those for logistic reasons)
It is a composite outcome. Any abnormal test findings during the study will be helpful in reviewing the outcome.
