Study Details

Study Description

Brief Summary

Main purpose

-To explore the safety and tolerance of human umbilical cord mesenchymal stem cells in the treatment of idiopathic pulmonary fibrosis (IPF).

Secondary purpose

  • To explore the preliminary efficacy of human umbilical cord mesenchymal stem cells in the treatment of idiopathic pulmonary fibrosis (IPF), and to recommend the appropriate dose of cell therapy for subsequent clinical studies.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Dose escalation

Four different doses were set, and three subjects in each dose plan received human umbilical cord mesenchymal stem cell injection successively. Each subject received a single dose of 6.0*10^6, 3.0*10^7, 6.0*10^7, and 9.0*10^7 cells / person.

Drug: Human umbilical cord mesenchymal stem cell injection
Different doses of human umbilical cord mesenchymal stem cell injection were infused to the focus of patients with idiopathic pulmonary fibrosis through bronchoscope, and the tolerance of subjects to different doses of human umbilical cord mesenchymal stem cell injection was observed, and the curative effect was preliminarily observed.

Outcome Measures

Primary Outcome Measures

  1. Tolerance of patients with idiopathic fibrosis to human umbilical cord mesenchymal stem cell injection [From the first administration to 4 weeks after administration]

    Incidence and severity of adverse events according to CTCAE5.0

  2. Dose exploration of patients with idiopathic fibrosis to human umbilical cord mesenchymal stem cell injection [From the first administration to 4 weeks after administration]

    The maximum tolerable dose (MTD) of a single administration depends on whether dose limiting toxicity (DLT) occurs within 4 weeks after the first administration, for example (1) Hematological toxicity of grade 3 and above caused by the treatment of human umbilical cord mesenchymal stem cell injection, (2) There are grade 3 and above non hematological toxic reactions caused by the treatment of human umbilical cord mesenchymal stem cell injection, except for the following cases, (3) Any other toxicity related to cell therapy that is higher than the baseline level is judged as clinically significant and / or unacceptable by the investigator and the sponsor, (4) There are acute exacerbations and serious adverse events (SAE) of IPF related to the treatment of human umbilical cord mesenchymal stem cell injection (which may be related, likely to be related and definitely related)

Secondary Outcome Measures

  1. Preliminary efficacy evaluation [The 4th, 12th, 24th and 48th week after administration]

    Changes from baseline in St. George's respiratory questionnaire SGRQ, dyspnea score, cough score and 6-minute walk test (grade and distance)in the treatment of idiopathic pulmonary fibrosis (IPF), and to recommend the appropriate dose of cell therapy for subsequent clinical studies

  2. Preliminary efficacy evaluation [The 4th, 12th, 24th and 48th week after administration]

    Changes in lung function (FVC, DLCO sb) compared with baseline

Other Outcome Measures

  1. Preliminary efficacy evaluation [The 4th, 12th, 24th and 48th week after administration]

    Changes in abnormal values of routine safety tests (blood routine, urine routine, blood biochemistry, 12 lead ECG, etc.) compared with baseline

  2. Preliminary efficacy evaluation [The 12th, 24th and 48th week after administration]

    Changes in chest HRCT scores from baseline

  3. Preliminary efficacy evaluation [The 12th, 24th and 48th week after administration]

    Changes of lung tumor markers from baseline

  4. Preliminary efficacy evaluation [Within 48 weeks after administration]

    Frequency and severity of acute exacerbations of IPF

  5. Immunogenicity of human umbilical cord mesenchymal stem cells [The 1st and 4th weeks after administration]

    Changes of specific immunoglobulin G (IgG) from baseline

  6. Immunogenicity of human umbilical cord mesenchymal stem cells [The 1st and 4th weeks after administration]

    Cytokines (TNF- α、 IFN- γ、 Changes of IL-2, IL-4, IL-5 and IL-6) from baseline
