Sutacimig for Glanzmann Thrombasthenia

(SOLARA Trial)

Glanzmann thrombasthenia (GT) is a serious inherited bleeding disorder. In GT, platelets, the blood cells that normally stick together at the site of an injury to stop bleeding, are unable to properly do so. As a result, bleeding does not stop as it should. Bleeding in GT often starts without warning, can happen frequently, and can be severe. It most commonly affects the nose, mouth and gums, gastrointestinal tract, and skin, and many women and girls with GT experience heavy menstrual bleeding. Over time, bleeding can lead to iron deficiency and anemia. Some bleeding episodes require emergency care, hospitalization, transfusion, or surgery, and some can be life-threatening.

Sutacimig is an investigational medicine given as an injection under the skin (subcutaneous injection). It is designed to help platelets work at the site of bleeding despite the underlying defect in GT. It is intended to be given regularly to help prevent bleeding (prophylaxis), rather than only to treat bleeding after it starts.

The purpose of this study is to find out whether sutacimig, given as prophylaxis, reduces the number of treated bleeding episodes in people with GT compared with no prophylaxis, and to evaluate its safety and tolerability.
