Multiple Sclerosis
Conditions
Brief summary
This is a randomized, parallel group, double-blind, active-controlled, clinical pharmacology study to compare Pharmacokinetics, Pharmacodynamics and safety of PB018 versus Ocrevus in patients with Multiple Sclerosis.
Detailed description
PB018, containing the active ingredient ocrelizumab, is a humanized monoclonal antibody that is being developed as a proposed biosimilar medicinal product to Ocrevus. The purpose of this study is to demonstrate similar PK, PD and safety of PB018 and Ocrevus in patients with Multiple Sclerosis.
