主要研究目的： 评价不同剂量的VUM02注射液治疗特发性肺纤维化（IPF）的安全性、耐受性。 次要研究目的： 1）评价不同剂量的VUM02注射液治疗特发性肺纤维化（IPF）的初步有效性，为后续临床研究推荐合适的细胞治疗剂量。 2）探索VUM02注射液治疗特发性肺纤维化（IPF）的免疫相关特征。

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.
