The MAPLE Study

The purpose of the MAPLE study is to evaluate the safety and efficacy of a study drug in adults with CIDP, including whether it can reduce disease progression and maintain nerve function in individuals with CIDP. 

Participants must meet the following criteria:  

Be 18 years of age or older

Have a confirmed diagnosis of CIDP including:

Typical, multifocal, or motor CIDP

Have clinical records documenting active disease, defined as evidence of at least 1 clinically meaningful deterioration within 2 years prior to screening.

Be on a maintenance regimen of IVIg, SCIg, or oral corticosteroids that has remained stable for 8 weeks prior to screening.

Participants are not eligible if they have:

Sensory, focal, or distal CIDP variants

Other eligibility criteria apply and will be evaluated by a principal investigator.

About the MAPLE Study

The MAPLE Study aims to assess whether a study drug can reduce disease progression and maintain nerve function in individuals with CIDP.

The study includes an optional open-label study after the randomized placebo-controlled part of the study, so all participants have the opportunity to receive the study drug following the conclusion of the treatment period.

Get started

Participants Will Be Expected To:  

Be randomized to receive either the study drug or placebo.

Visit the research site up to 20 times during the study which lasts around 2.5 years.

The study drug or placebo is delivered three times during the treatment period and an additional three times if participating in the open-label period.
