A Study of TAK-755 in Participants With Congenital Thrombotic Thrombocytopenic Purpura

Exploring TAK-755 for congenital thrombotic thrombocytopenic purpura (TTP).

Phase 3

Thrombotic thrombocytopenic purpura (TTP) is a condition where blood clots form in small blood vessels, which can cause serious health problems by blocking oxygen-rich blood from reaching organs. It also uses up platelets, which help blood clot, leading to bleeding and purple bruises (purpura). TTP can cause anemia, where red blood cells break apart faster than they are replaced. The lack of a protein called ADAMTS13, which helps control clotting, causes TTP.

This study tests a medicine called TAK-755 that replaces ADAMTS13 to prevent or control TTP flare-ups. The study checks for side effects of long-term TAK-755 treatment, given either weekly or when a flare-up happens. Participants will be in the study for up to 3 years, receiving treatment at home or a clinic.

Three key points:

  • The study lasts up to 3 years with regular clinic visits.
  • Treatment can be at home or in a clinic, depending on the group.
  • The study checks for side effects of TAK-755 in long-term use.

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
