Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multi-center, randomized, parallel arm, double-blind study with a total duration of subjects' participation of 48 weeks. Approximately 260 participants with relapsing-remitting multiple sclerosis will be randomized to receive 12 doses of either PB006 or EU-licensed Natalizumab.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 3 multicenter, double-blind, active-controlled, randomized, parallel-group study to assess the equivalence in efficacy and similarity in safety of biosimilar PB006 compared to Tysabri in patients with RRMS.

All eligible patients will be randomly assigned to one of two treatment groups in a 1:1 ratio, to receive a total of twelve intravenous (IV) infusion of either PB006 or Tysabri at a dose of 300 mg at each intravenous (IV) infusion administered with every single one intravenous (IV) infusion administered every 4 weeks of either PB006 or Tysabri at a dose of 300 mg starting at visit 1 (week 0) through visit 12 (week 44), for a total of 12 infusions. The End-of-Study Visit (visit 13, week 48) will be performed 4 weeks after the last infusion

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

PB006

Patients with relapsing-remitting multiple sclerosis (RRMS) received intravenous (IV) infusions every 4 weeks of PB006 at a dose of 300 milligram (mg) starting at Visit 1 (Week 0) through Visit 12 (Week 44), for a total of 12 infusions.

Group Type EXPERIMENTAL

Intravenous (IV) infusions

Intervention Type BIOLOGICAL

Intravenous (IV) infusions of a dose of 300mg, every 4 weeks with a total of 12 doses

Tysabri

Patients with relapsing-remitting multiple sclerosis (RRMS) received intravenous (IV) infusions every 4 weeks of Tysabri at a dose of 300 milligram (mg) starting at Visit 1 (Week 0) through Visit 12 (Week 44), for a total of 12 infusions. At Week 24, patients in the Tysabri group were re-randomized through a re-randomization step. Patients re-randomized and switched from Tysabri to PB006 at Week 24 still received a total of 12 infusions (6 infusions of Tysabri and 6 infusions of PB006).
