What are clinical research studies?

Has your essential thrombocythemia (ET) therapy stopped working?

You may be eligible to join a Phase 3 clinical research study in the U.S. that evaluates the potential of a new, investigational ET therapy to reduce the number of platelets in the blood.

What is Essential Thrombocythemia?
Essential Thrombocythemia

Essential thrombocythemia (ET) is a condition characterized by an excessive increase of the number of platelets in your blood. Platelets cause blot clots and vascular complications. Some people with ET have no symptoms, while others develop many health problems due to additional platelets in the blood.

Symptoms can include the following:

ET can also cause more serious problems from increased risk of blood clots, including strokes and heart attacks, although these are rare events.
Controlling the number of platelets in the blood can help to reduce these
symptoms and health risks.

The P1101 ET Study

The P1101 ET study is for people with ET, who have tried other therapy options, like hydroxyurea, that are no longer effective at controlling their ET or that have such extreme side effects that people stop using them. The goal of this study is to compare the new study therapy, ropeginterferon alfa-2b (P1101), to the approved ET therapy, anagrelide.

The study therapy (P1101) is considered investigational because it has not been approved for public use in ET and can only be used in clinical research studies like this P1101 ET study. The study therapy (P1101) is designed to reduce the number of platelets in the blood. It is given as an injection under the skin every 2 weeks.
