An Immunogenicity and Pharmacokinetics (PK) Study of BIIB019 (Daclizumab High Yield Process (DAC HYP)) Prefilled Syringe in Relapsing Remitting Multiple Sclerosis (RRMS) — OBSERVE  

Relapsing-Remitting Multiple Sclerosis Clinical Trial

Official title: A Multicenter, Single-Arm, Open-Label Study to Evaluate the Immunogenicity and Pharmacokinetics (PK) of (BIIB019) Daclizumab High Yield Process (DAC HYP), Prefilled Syringe Administered by Subcutaneous Injection in Subjects With Relapsing-Remitting Multiple Sclerosis (RRMS)

Status Active, not recruiting

Clinical Trial Summary

The primary objective of the study is to assess the immunogenicity of Daclizumab High Yield Process (DAC HYP) 150 mg administered every 4 weeks by subcutaneous (SC) injection using the pre-filled syringe (PFS) in participants with relapsing-remitting multiple sclerosis (RRMS). The secondary objectives of this study are to characterize the pharmacokinetic (PK) of DAC HYP following single and multiple doses of DAC HYP administered by the PFS in a subset of participants with RRMS and to evaluate the effect of DAC HYP on the PK of probe drugs for cytochrome P450 (CYP) isoenzymes (CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A).

Clinical Trial Description

Following a screening period, participants will receive DAC HYP over a 24-week treatment period (6 monthly injections) and then enter a 20-week washout period for monthly assessment of immunogenicity, pharmacokinetic (PK), pharmacodynamics (PD), safety and tolerability. The 20-week washout is necessary to ensure measurement of anti-DAC HYP binding antibodies (ADAbs) and neutralizing antibodies (NAbs) in the absence of drug interference. After washout, the participants may resume monthly treatment with DAC HYP 150 mg for an additional 3 years. All participants will be followed for 6 months after their last dose for safety monitoring. Additionally, two sub-studies will be performed; (1) an intensive serial PK sampling performed over the first and last dosing interval following DAC HYP doses administered at week 0 and at week 20, and (2) a therapeutic protein-drug interaction (TP-DI) sub-study, during which a probe drug cocktail will be administered at weeks 43 and 53 followed by serial probe-drug PK sampling up to 96 hours after probe-drug administration. A maximum of 20 participants will be enrolled in the TP-DI sub-study. ;
