About this study

Official title: A Phase I Open Label, Dose Escalation Study to Characterize the Safety, Tolerability, and Efficacy of VUM02 Injection in Subjects With Idiopathic Pulmonary Fibrosis

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.

Read the detailed 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VUM02 Injection in people with Idiopathic Pulmonary Fibrosis, run by Wuhan Optics Valley Vcanbiopharma Co., Ltd. at 4 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence and severity of cell therapy-related adverse events (AEs) as assessed by CTCAE (V5.0) (time frame: 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jul 2026.
