This is a single-arm, open-label, multicenter, ascending dose Phase 1/2 trial evaluating the safety and preliminary efficacy of CTX112 or Zugocabtagene geleucel (zugo-cel) in adult participants with relapsed/refractory primary Immune Thrombocytopenia (ITP) and relapsed/refractory primary Warm Autoimmune Hemolytic Anemia (wAIHA).
This trial will assess the safety and preliminary efficacy of CTX112 or Zugocabtagene geleucel (zugo-cel) in adults with relapsed or refractory hematologic autoimmune diseases (AID), including primary ITP and primary wAIHA. In these B-cell-mediated conditions, autoantibodies target platelets (ITP) or red blood cells (wAIHA), causing severe thrombocytopenia or anemia. Although several treatments exist, some patients relapse or remain refractory, resulting in significant morbidity, mortality, and reduced quality of life. This underscores the need for new therapeutic options. B-cell-directed the…
