Study of genetic and blood features in Upshaw-Schulman

Thrombotic Thrombocytopenic PurpuraCongenital Thrombotic Thrombocytopenic PurpuraFamilial Thrombotic Thrombocytopenic PurpuraThrombotic Thrombocytopenic Purpura, CongenitalUpshaw-Schulman Syndrome

Part of Blood & lymphatic clinical trials.

This study looks at how genetic changes (ADAMTS13 gene mutations) and blood test results relate to symptoms and treatment needs in Upshaw-Schulman syndrome. It may help doctors better predict disease behavior and personalize care.

Who can take part

  • Your blood test shows very low ADAMTS13 activity (10% or less) on at least two checks.
  • Your tests do not show an anti-ADAMTS13 immune blocker (inhibitor) on those repeat checks at least one month apart.
  • You are a family member of someone with confirmed or suspected Upshaw-Schulman.
  • You have genetic testing of the ADAMTS13 gene showing one or more mutations, or
  • You have had a trial of infusion treatment where ADAMTS13 activity fully returned after fresh frozen plasma (FFP), and the levels fell with a half-life of about 2–4 days.

Aspirin to help prevent TTP episodes

This trial studies whether taking aspirin can prevent TTP (thrombotic thrombocytopenic purpura) from coming back or worsening. It is for people with very low ADAMTS13 activity, a key blood marker tied to TTP risk.

Study of a treatment for congenital TTP

This study looks at how patients with a rare blood disorder called congenital thrombotic thrombocytopenic purpura (cTTP) are doing while being treated with a replacement therapy called recombinant ADAMTS13. It aims to understand real-world experiences and outcomes.

Building a database for severe ADAMTS13 deficiency

This trial is creating a research database for people with severe ADAMTS13 deficiency, a condition where the body has very low activity of a key blood-protein. It may help researchers better understand the condition by collecting and organizing patient information.

A study on treatment for people with congenital TTP who received ADAMTS13

This study looks back at medical records of people with a rare blood disorder called congenital thrombotic thrombocytopenic purpura (cTTP) who received a treatment called recombinant ADAMTS13 (rADAMTS13). The goal is to learn more about how this treatment works in real life.

Living with aTTP? Join a national patient registry study

This study is a national registry that collects medical information from people diagnosed with a type of blood-clotting disorder called acquired TTP (aTTP). It may help researchers better understand the disease and how it’s managed, without necessarily changing your treatment.
