Summary

At present, the diagnosis of IPF is still difficult and it cannot be completely cured. Treatment is still aimed at improving symptoms and delaying the decline of lung function. The treatment measures for IPF mainly include drug therapy ( pirfenidone and nintedanib), non-drug therapy (such as oxygen therapy, pulmonary rehabilitation), treatment of complications/comorbidities, symptomatic treatment and palliative treatment. However, IPF cannot be completely cured at present, so lung transplantation is a feasible option for the treatment of IPF. However, due to the scarcity of donor lungs, prevention of acute and chronic rejection reactions, post-transplant infection complications, and high costs, its clinical implementation is limited. Therefore, there is still a large unmet treatment need for IPF, and new therapeutic drugs are urgently needed. In recent years, mesenchymal stem cells (MSCs) have been considered a new hope for the treatment of IPF. MSCs are a type of multipotent stem cells with the potential for self-proliferation and differentiation. They have the characteristics of self-renewal, multidirectional differentiation, low immunogenicity, and paracrine. They can automatically home to damaged areas, promote epithelial tissue repair, inhibit inflammation, and inhibit abnormal proliferation of fibroblasts . Many clinical trials at home and abroad are exploring the effectiveness and safety of MSC in the treatment of pulmonary fibrosis. An Australian study found that in patients with moderate to severe IPF, intravenous infusion of umbilical cord MSCs up to 2 × 106 cells/kg was safe, and no decrease in forced vital capacity (FVC), diffusing vital capacity for carbon monoxide (DLCO), 6-minute walk test distance (6MWD), and CT fibrosis score was observed during a 6-month follow-up . The results of the American AETHER study also showed that a single intravenous infusion of up to 2 × 10\^ 8 cells of bone marrow MSCs was safe, with no serious treatment-related adverse events observed. Moreover, 60 weeks after infusion , FVC% decreased by 3.0% and DLCO% decreased by 5.4%, both of which were below the threshold for disease progression . This study adopted a multicenter, randomized, double-blind, placebo-controlled, parallel design to evaluate the efficacy and safety of SC01009 injection in IPF subjects . This study plans to enroll 66 subjects, who will be randomly stratified according to whether they have received oral pirfenidone/nintedanib treatment at screening , and randomly assigned to two trial groups and one placebo group in a 1:1:1 ratio. This study includes a screening period of up to 4 weeks, a 24-week treatment follow-up period, and a 2-year long-term follow-up period. After screening, qualified subjects will be given medication according to the following dosing schedule according to their group: Trial Group 1: received intravenous infusion of SC01009 injection in week 1, divided into 3 infusions every other day, each infusion of 3 × 10\^ 7 cells, with a total dose of 9 × 10 \^7 cells; received intravenous infusion of placebo in week 13, with the same administration method as in week 1; Experimental group 2: received intravenous infusion of SC01009 injection at week 1 and week 13, respectively. Each administration was divided into 3 infusions every other day, with 3 × 10\^7 cells in each infusion , and the total dose was 1.8 × 10\^8 cells. Placebo group: received intravenous infusion of placebo at week 1 and week 13, respectively, with the same administration method as the cell therapy group. After completing 24 weeks of treatment follow-up, all subjects entered the long-term follow-up phase and were unblinded after the study database was locked . The subjects in the original placebo group could end the follow-up, while the subjects receiving cell therapy would continue to be followed up for up to 2 years.

Interventions

BIOLOGICAL

SC01009 injection

Menstrual Blood-Derived Mesenchymal Stem Cell (Product Code: SC01009) Injection is a cell therapy product developed by Zhejiang Sinocord Precision Medicine Technology Co., Ltd. The active component consists of mesenchymal stem cells (MSCs) derived from menstrual blood.

BIOLOGICAL

Placebo Group(Vehicle)

The placebo consists of the SC01009 Injection formulation solution, containing all components identical to the active product except for the absence of mesenchymal stem cells.
