Details and patient eligibility

About

MABPS-3/2020 is a double-blind randomized multicenter clinical trial comparing efficacy, immunogenicity and safety profiles of Adalimumab (manufactured by Mabscale, LLC) compared to Humira®.

The purpose of the study is to demonstrate efficacy, immunogenicity and safety of Adalimumab (manufactured by Mabscale, LLC) to Humira ® in adult patients with chronic plaque psoriasis of moderate and severe degree.

Full description

Adalimumab is a recombinant humanized monoclonal antibody currently being developed by Mabscale LLC, as a proposed biosimilar to Humira®, which is approved as treatment in patients with chronic plaque psoriasis.

This randomized equivalence study is designed to meet the regulatory requirement for approval of a biosimilar product.

494 participants in 2 patient groups

Adalimumab (manufactured by Mabscale, LLC)

Experimental group

Description:

In the main period, patients will begin Visit 1 receiving Adalimumab therapy at an initial dose (80 /0, 16 ml) on Visit 1, from Visit 2 Adalimumab therapy at a maintenance dose (40 /0, 8 ml) for up to Visit 9 of therapy. Each visit is conducted every two weeks ± 2 days. In additional period (from Visit 11 until Visit 28), eligible patients will continue to receive treatment after additional randomization (Adalimumab or Humira® (40 /0, 8 ml)) every 2 weeks until the end of a trial.

Treatment:

Drug: Adalimumab

Humira®

Active Comparator group

Description:

In the main period, patients will begin Visit 1 receiving Humira® therapy at an initial dose (80 /0, 8 ml) on Visit 1, from Visit 2 Humira® therapy at a maintenance dose (40 /0, 4 ml) for up to Visit 9 of therapy. Each visit is conducted every two weeks ± 2 days. In additional period (from Visit 11 until Visit 28), eligible patients will continue to receive treatment after additional randomization (Adalimumab or Humira® (40 /0, 4 ml)) every 2 weeks until the end of a trial.

Treatment:

Drug: Humira
