Details and patient eligibility

About

BCD-131 is pegylated darbepoetin beta. This clinical study BCD-131-3 is a randomized, open-label, phase III study of the efficacy and safety of BCD-131 and Mircera used for the treatment of anemia in end-stage chronic kidney disease (CKD) patients on dialysis.

Full description

This clinical study is based on the hypothesis that BCD-131 is non-inferior to Mircera when used for the treatment of anemia in dialysis patients with end-stage CKD after 32 weeks of therapy.

The study is intended to include subjects with stage 5 CKD, receiving dialysis for at least 90 days before signing the ICF (for patients on hemodialysis - a least 3 times per week and at least 12 hours per week of standard hemodialysis), with established dialysis efficacy, with anemia of renal origin, without other causes for anemia (anemia of chronic disease, vitamin B12 deficiency, folic acid deficiency, iron deficiency, etc.).

This is a study of efficacy of BCD-131 as a maintenance therapy, therefore the population includes patients who have been receiving stable doses of erythropoietins (epoetin alfa, epoetin beta or darbepoetin alfa) for at least 3 months prior to signing the informed consent form (ICF) and throughout the screening period and with target hemoglobin level (100-120 g/L) maintained for at least 2 weeks before the ICF signing and at the screening.

The study includes the following periods:

Screening period (28 days),
Main period (32 weeks), consisting of dose titration (weeks 0-12) and maintenance therapy (weeks 13-32) - for the primary efficacy analysis
Extension period (weeks 33-52) - for long-term safety and efficacy assessment
Follow-up period (weeks 53-56)

Inclusion criteria

The patient signed a written ICF for participation in the study.
Men and women aged 18 to 75 years inclusive at the time of signing the ICF.
End stage kidney disease (documented).
The need for dialysis sessions within at least the last 90 days prior to signing the ICF.
For patients on hemodialysis - hemodialysis procedures should be at least 3 times a week, for a total duration of at least 12 hours a week.
Documented use of recombinant erythropoietin (epoetin alfa, epoetin beta or darbepoetin alfa) for at least 90 days prior to signing the ICF.
The dose of recombinant erythropoietins (epoetin alfa or epoetin beta received 1, 2 or 3 times a week, or darbepoetin alfa received once a week/once every 2 weeks) should be stable for at least 90 days prior to signing the ICF and the entire screening period (documented).
Target hemoglobin level (100-120 g/L inclusive) based on the results of screening examination (two measurements).
The efficacy of dialysis established at screening or not more than 14 days before signing the ICF (dialysis dose index (Kt/v) ≥1.2 in patients on long-term hemodialysis, and weekly Kt/v ≥1.7 for patients on peritoneal dialysis).
Transferrin saturation ≥20%, ferritin level >100 ng/mL at screening.
Cyancobalamine (vitamin B12) and folic acid levels within the laboratory reference values at screening.
Willingness of patients of both sexes and their sexual partners of childbearing potential to use methods of contraception in accordance with the protocol, starting from signing the informed consent form, throughout the study and for up to 90 days after receiving the last dose of the drug in the clinical study, as well as to refrain from donation of eggs for female subjects or sperm for male subjects during this period.
The ability of the patient to comply with the Protocol requirements, in the Investigator's opinion.

Exclusion criteria

A history of severe allergic reactions (anaphylactic shock or multiple drug allergy) according to the patient, and hypersensitivity to recombinant erythropoietins, polyethylene glycol or any components of the study drugs, or to iron (III) hydroxide sucrose complex.
Vaccination less than 8 weeks before signing the ICF (according to the patient).
Diagnosed liver cirrhosis.
HIV infection.
ALT, AST >3хULN at screening.
