TAK-411 for Chronic Inflammatory Demyelinating Polyradiculoneuropathy
(CASCA Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called TAK-411, an experimental therapy for individuals with Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP). In this condition, the immune system mistakenly attacks the protective coating of nerves. The trial aims to determine if TAK-411 can reduce inflammation and improve muscle strength and sensation. Participants will receive the treatment for up to a year and attend clinic visits to monitor progress. Suitable candidates are adults with CIDP who have previously responded to similar treatments and have experienced a recent worsening of symptoms. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to the development of a potentially effective therapy.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you must be on a stable dose of immunoglobulin treatment. You cannot take certain immunosuppressive drugs or have had plasma exchange recently.
Is there any evidence suggesting that TAK-411 is likely to be safe for humans?
Research shows that TAK-411, a modified form of the protein immune globulin G (IG), is under study to determine its safety and effectiveness for treating Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP). Previous studies have found that treatments like TAK-411 are usually well-tolerated by patients. However, TAK-411 is currently in Phase 2 of clinical trials, and researchers are still learning about its full safety profile.
This phase tests the treatment on a larger group to better understand its safety. Although TAK-411 is still under investigation, similar treatments have been used safely for other conditions. So far, no serious side effects have been reported, but all potential treatments can carry some risks. Trial participants will be closely monitored to ensure their safety.12345Why do researchers think this study treatment might be promising for CIDP?
Most treatments for Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) involve immunoglobulin therapy, corticosteroids, or plasmapheresis. However, TAK-411 stands out because it is administered through an intravenous infusion with a specific dosing schedule that starts with a higher induction dose. This approach might provide a more consistent therapeutic effect over time. Additionally, TAK-411's dosing regimen is structured to potentially offer quicker symptom relief, which could be a game changer in managing this chronic condition. Researchers are excited about TAK-411 because of its potential to offer a more targeted and possibly more effective treatment option for those with CIDP.
What evidence suggests that TAK-411 might be an effective treatment for CIDP?
Research shows that TAK-411, a modified form of the protein immune globulin G, might help treat CIDP by reducing inflammation and improving symptoms. Studies have found that treatments using immune globulin G effectively protect nerves from immune system attacks in CIDP. Early results suggest that TAK-411 enhances this protective effect, potentially leading to better nerve function and less muscle weakness. While researchers are still gathering specific data on TAK-411's effectiveness in humans, its design is based on proven methods that have helped CIDP patients in the past.12467

Are You a Good Fit for This Trial?
Adults with Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP), a condition where the immune system attacks nerve coverings, leading to muscle weakness and sensory loss. Participants should have stable CIDP symptoms and be able to visit the clinic up to 21 times over a year.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- TAK-411
Trial Overview
The trial is testing TAK-411, an altered form of immunoglobulin G derived from human plasma, designed to reduce inflammation and improve CIDP symptoms. It compares TAK-411's effects on physical functioning against historical placebo group data.

Experimental Treatment
Participants will receive TAK-411 400 milligrams per kilogram (mg/kg), IV infusion as an induction dose on Day 1 of initial treatment period. The induction dose may be repeated once after 3 weeks if participants exhibit no clinical change. Thereafter, participants will receive TAK-411 200 mg/kg, IV infusion every 3 weeks for a total of 24 weeks (initial treatment period), followed by an optional additional 27 weeks (extended treatment period).
