New drug combo aims to tame stubborn blood disorders
NCT ID NCT07574073
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tests whether combining two drugs (Zuberitamab and Orelabrutinib) can help people with immune thrombocytopenia (ITP) or autoimmune hemolytic anemia (AIHA) that hasn't responded to other treatments. The drugs work together to calm the immune system and stop it from attacking the body's own blood cells. The study will enroll 30 adults and focus on safety and how well the combination works.
