Ulcerative Colitis Clinical Trial
— UCOfficial title:
A Phase IB/IIA Study of Remestemcel-L, an ex Vivo Culture-expanded Adult Allogeneic Bone Marrow Derived Mesenchymal Stem Cell Product, for the Treatment of Medically Refractory Ulcerative Colitis
The purpose of this study is to determine the safety and efficacy of using remestemcel-L, an ex vivo culture-expanded adult allogeneic bone marrow derived mesenchymal stem cell product (MSCs) delivered by targeted endoscopic delivery to treat people for medically refractory ulcerative colitis. This study will enroll adult patients with medically refractory ulcerative colitis who are planning to switch biologic therapy or undergo colectomy as the next stage in their treatment plan.
