Clinical Trial Summary

The goal of this clinical trail is to study the efficacy and safety of allogeneic adipocyclical active protein in the treatment of severe idiopathic pulmonary fibrosis.

The main questions it aims to answer are:

1. Efficacy of allogeneic adipromic active protein in the treatment of severe idiopathic pulmonary fibrosis

2. Safety of allogeneic adipovularic active protein in the treatment of severe idiopathic pulmonary fibrosis.

A total of 7 participants will be enrolled. Participants will be asked that they will receive 2ml of each nebulized inhalation Cell Free Fat Extract (CEFFE), inhaled every 3 days, for a total of 7 nebulized inhalation treatments.

The clinical trial was designed using a single-center, self-controlled trial with no control group and no blinding.

Clinical Trial Description

1. Research purpose:

Main Objective: To study the efficacy and safety of allogeneic adipocyclical active protein in the treatment of severe idiopathic pulmonary fibrosis, and the main observation and evaluation indicators include: clinical efficacy, clinical adverse events and laboratory abnormalities.

The basis of the question:

Animal experiments have found that Cell Free Fat Extract (CEFFE) has a certain improvement effect in bleomycin-induced mouse pulmonary fibrosis model. At present, domestic clinical studies have found that Cell Free Fat Extract (CEFFE) is safe for the treatment of human diseases without obvious side effects. Therefore, in this study, the Cell Free Fat Extract (CEFFE) was inhaled by nebulized inhalation for the treatment of severe idiopathic pulmonary fibrosis, and its efficacy and safety were observed.

2. Research Design:

Overall design: single-center, self-controlled trial design was adopted, no control group was established, and blinding was not used.

Number of planned cases: 7.

Indications: severe idiopathic pulmonary fibrosis.

3. Clinical trails process:

3.1 Sign the informed consent form and collect relevant clinical data; For patients with a definitive diagnosis of severe idiopathic pulmonary fibrosis

3.2 Allogeneic Cell Free Fat Extract (CEFFE) treatment process:

3.2.1 Preparation of CEFFE of allogeneic origin: Healthy donors undergoing liposuction at the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, sign a written informed consent. By a healthy donor under local anesthesia, inject swelling fluid into the abdomen, operate with a 20mL syringe or mechanical negative pressure machine (auxiliary liposuction methods such as laser, ultrasound and microwave cannot be added), determine the group according to the order of enrollment, and extract fat according to the required dose, and the single liposuction amount should be 150ml -200ml. The collected adipose tissue was rinsed with normal saline, allowed to stand, and centrifuged in a centrifuge at 1200g for 3min. After centrifugation, excess water at the bottom is removed, collected in a sterile 50mL syringe, stored, and transferred. Preparation of adipose tissue active factors is performed in the laboratory and cryopreservation. Two 10mL syringes connected by tee tubes, mechanically emulsified 60 times, collected into 50mL centrifuge tubes, centrifuged at 2000g for 5min. After centrifugation, the bottom transparent liquid layer was collected and filtered through a 0.22um filter to obtain fat decellularization active protein, which was frozen in a -20 °C freezer.

3.2.2 Health Donor Selection Criteria:

3.2.2.1 Age 18-45, male or female

3.2.3.3 Patients with tumors or previous history of tumors

3.3 After negative percutaneous test, allogeneic CEFFE is inhaled by nebulization; 0.2ml CEFFE was injected intradermally 1 cm above the palmar stria on the palmar side of the right forearm, and 0.2ml of normal saline was injected intradermally 1 cm above the palmar stria on the palmar side of the left forearm as a control. Interpretation of skin test results: local pichu bulge, and red halo hard lump, diameter > 1 cm is positive.

Give a single dose of 2ml allogeneic CEFFE stock solution (protein concentration of 3mg/ml), administered by nebulization inhalation, 8 minutes between each atomization time, 3 days apart; A total of 7 doses were given.

3.4 Observe the clinical symptoms, chest CT, lung function and related adverse reactions of patients at 1, 3, 6 and December after the end of allogeneic fat decellularization active protein treatment.

4. Evaluation Criteria:

4.1 Efficacy criteria:

4.1.1 Obvious effect means that the main symptoms and signs are significantly relieved, and the objective indicators are significantly improved.

4.1.2 Effective means that the main symptoms and signs have improved, and the objective indicators have improved.

4.1.3 Ineffective means that the main symptoms and signs have not changed, and the objective indicators have not changed significantly or worsened.

4.2 Safety evaluation:

Clinical adverse events and laboratory tests are definitely related to allogeneic CEFFE treatment, likely related to allogeneic CEFFE treatment, may be related to allogeneic CEFFE treatment, may not be related to allogeneic CEFFE treatment, and may not be related to allogeneic CEFFE treatment.

4.3 Evaluation endpoints: Clinical efficacy, comprehensive efficacy and safety evaluation at 1, 3, 6 and 12 months after the end of treatment were the main evaluation endpoints.
