Recruiting at 39 sites Phase 2 Immune Thrombocytopenia

Immune Thrombocytopenia study: INCA000585

Official title Study to Assess the Safety and Tolerability of Tafasitamab in Adult Participants With Primary Autoimmune Blood Cell Disorders

ClinicalTrials.gov ID: NCT07104565

What this study is testing

What is INCA000585?

This is an investigational medicine being studied to see if it helps treat Immune Thrombocytopenia. It is designed to target specific cells in the immune system to help manage the condition.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study wants to see how safe and well tolerated tafasitamab is, and whether it works for people with this blood disorder.
Who it's for
Adults who have immune thrombocytopenia, a condition where the immune system attacks platelets.
What's involved
Participants will receive tafasitamab and have regular visits and blood tests to monitor safety and effectiveness.
