Clinical Trial Summary

This study is a single-arm, multiple-dose, dose-escalation, open-label multicenter clinical trial, aiming to evaluate the safety, tolerability, and preliminary efficacy of VUM02 Injection for treatment of idiopathic pulmonary fibrosis (IPF). VUM02 Injection (Human Umbilical Cord Tissue-derived Mesenchymal Stem Cells Injection, hUCT-MSC) is an allogeneic cell therapy product comprising culture-expanded Mesenchymal Stem Cells derived from the human umbilical cord tissue. The product is cryopreserved with the amount of 5 x 10^7 cells per 10 mL per bag (5 x 10^6 cells/mL). This study is a multiple-dose tolerability study following the "3+3" dose escalation principle and progressing from the low-dose group to the high-dose group sequentially. Three to six patients will be enrolled in each dose group and administered every 3 days for a total of 3 doses.

Description:

This trial includes three predefined dose groups: low dose (5E7 cells/person/time), medium dose (1E8 cells/person/time), and high dose (2E8 cells/person/time) groups, for a multiple-dose tolerability study. Each dose group undergoes an initial safety and tolerability assessment with a single dose. After receiving the initial dose, subjects undergo safety evaluations on Day 3 (including symptom assessment, physical examination, vital signs monitoring, 12-lead electrocardiogram, hematology, urinalysis, blood biochemistry, and coagulation function tests). The decision to proceed with subsequent administrations for subjects who have received the initial dose is made through discussion between the investigator and the sponsor (and/or CRO medical staff) based on safety profiles. This study follows the "3+3" dose escalation principle, progressing from the low-dose group to the high-dose group sequentially. The sample size may be adjusted based on the actual circumstances of the trial, with each subject receiving only one corresponding dose. During the study, a Safety Monitoring Committee (SMC) will be established, consisting of the investigators and representatives from the sponsor. The SMC will review the safety data generated during the study and make decisions regarding dose escalation, modification of escalation doses, alteration of dosing regimens, or study discontinuation. Only after all subjects in the preceding dose group have completed the dose-limiting toxicity (DLT) observation, and the SMC confirms that the dose escalation criteria are met, the enrollment for the next dose group will begin.
