Study Details
Study Description
Brief Summary
The goal of this clinical study is to establish the comparability of the pharmacokinetics and similarity of the safety, immunogenicity and pharmacodynamic profiles of BCD-264 and Darzalex following a single intravenous infusion in healthy subjects.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|
| Phase 1 |
Detailed Description
In this clinical study, each subject will receive a single intravenous infusion of BCD-264 or Darzalex, depending on the group the subject will be randomized to. The drugs are administered at the study site at a dose of 8 mg/kg.
The subjects will be followed up and blood samples collected for pharmacokinetics, pharmacodynamics, immunogenicity and safety studies up to and including 71 study days after the administration of IP.

-
Willingness to refrain from taking any medications, including over-the-counter drugs, vitamins and food supplements, with the exception of drugs prescribed by the investigator for the treatment of AEs, throughout the study.
-
Willingness to refrain from donating blood and plasma for 6 months after the IP administration.
Exclusion Criteria:
-
