Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A single-center, prospective, randomised controlled clinical trial (1:1 treatment ratio), designed to investigate the efficacy and safety of autologous SVF in improving the pregnancy outcome of infertile patients with POI.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A single-center, large-scale, prospective, randomized controlled clinical trial will enroll 260 patients diagnosed with POI based on the inclusion and exclusion criteria from Peking University Third Hospital. Eligible participants will be randomized to two groups at a ratio of 1:1- SVF protocol, and conventional protocol.The participation in this study will be approximately 2 years with a total of 6 visits and 3 follow-up phone calls.

SINGLE

Outcome Assessors
Due to the particularity of the treatment plan, the evaluator, namely the follow-up personnel who collect the postoperative medical history and the ultrasound evaluator, will be blinded in this trial to hide the grouping results. Blinding of participants and researchers is not possible.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A-SVF group

Qualified participants will be randomized into either of two groups. Participants in this group will undergo lower abdominal liposuction, preparation of SVF and ovarian injection, other standard assisted reproductive treatments are similar and parallel between two groups.

Group Type EXPERIMENTAL

Lower abdominal liposuction and preparation of SVF

Intervention Type PROCEDURE

After lower abdominal liposuction (the liposuction volume is about 100 ml), the preparation and quality inspection of SVF will be completed by a laboratory with good manufacturing practice-approved facilities immediately. The adipose tissue will be cut into pieces of about 1mm3, and the equal volume of 0.1% collagenase I will be added to digest the adipose tissue. The digestion will be terminated after 40 minutes, followed by isolation, filtration, centrifugation, resuspension and dilution to obtain the SVF suspension. The test items, including bacteria, fungi, viruses and endotoxin, will be tested, and the expression of SVF surface markers, including CD45, CD34, CD31, CD11b, CD44, CD73, CD105 and CD90, will be detected by flow cytometry to ensure the quality of the SVF suspension. After about 4 hours of quality control and detection, the SVF suspension will be transported to the operating room on ice in a sealed incubator.

Ovarian injection

Intervention Type PROCEDURE

Under ultrasound guidance, the SVF suspension will be injected into patients' bilateral ovaries. SVF with a total amount of (1\~2)×107 cells from autologous fat tissue will be transplanted into each side of ovary. There are 3 injection points on each side of ovary, and 330±10μl SVF suspension will be administered at each point. The administration volume of each ovary will be 1ml in total. After injection, the patients will be required to lie flat for 2 hours to observe whether there would be adverse events.

Group B-Control group

Qualified participants will be randomized into either of two groups. Participants in this group will be treated according to the current clinical routine of the reproductive center, other standard assisted reproductive treatments are similar and parallel between two groups.

Group Type OTHER

Conventional IVF

Intervention Type PROCEDURE

Conventional In Vitro Fertilization (IVF) procedure and standard assisted reproductive treatments.
