Crohn's Disease Activity Index (CDAI) at or below 150 and increase in IBDQ
Treatment was considered a success if all of the following conditions were met: Achieved induction of a complete response (CR) within 28 days after first infusion; CR followed by 28 days maintenance of a clinically meaningful response defined as the response that did not require an increase in corticosteroid dose (methylprednisolone doses \>2 milligram/kilogram/day \[mg/kg/d\] or prednisone doses \>2.5 mg/kg/d) for more than 7 consecutive days; Did not require second line/escalation therapy through Study Day 56; and survived 90 study days.
A complete response was defined as complete resolution of all clinical signs of Graft versus host disease (GVHD)- that had to be maintained for at least 28 consecutive days (durable complete response \[DCR\]) within 100 days post first infusion.
Responses included complete response (CR), partial response (PR), failure to respond. CR is defined as a complete resolution of graft-versus-host disease (GVHD). PR is defined as improvement in at least one organ by at least one full stage in the absence of progression in any other organ, or resolution of GVHD in at least one organ with a need for additional treatment because of abnormalities persisting in another organ. Failure to respond is defined as progression of GVHD.

PROCHYMAL is an investigational stem cell therapy being studied for Crohn's Disease, Graft Versus Host Disease, Type 1 Diabetes Mellitus, Myocardial Infarction, Pulmonary Disease, and Chronic Obstructive Pulmonary Disease. It is developed by Mesoblast Limited (MESO) and is currently in Phase 2 clinical development.
PROCHYMAL is a small molecule therapeutic that targets inflammatory and immune-mediated pathways. It is being evaluated for its potential to modulate the immune response in conditions like Crohn's Disease and Graft Versus Host Disease. The specific molecular target has not been disclosed.
PROCHYMAL is developed by Mesoblast Limited, a biopharmaceutical company traded under the ticker MESO. Mesoblast is conducting clinical trials to evaluate the safety and efficacy of PROCHYMAL across multiple indications, including Crohn's Disease and Type 1 Diabetes Mellitus.
PROCHYMAL is in Phase 2 clinical development. It is an investigational therapy and has not been approved by regulatory authorities. Mesoblast has completed several clinical trials, including Phase 2 and Phase 3 studies, but the drug remains under investigation.
PROCHYMAL has been studied in several completed clinical trials, including NCT00482092 for Crohn's Disease, NCT00690066 for Type 1 Diabetes Mellitus, and NCT00877903 for Myocardial Infarction. These trials were randomized, double-blind, and placebo-controlled, with a total enrollment of 463 participants.
PROCHYMAL is also known as remestemcel-L, a name used in some clinical contexts. It is an investigational stem cell therapy developed by Mesoblast Limited. The drug has been evaluated in clinical trials for various conditions, including Crohn's Disease and Myocardial Infarction.
