研究目的:

在体外受精胚胎-移植治疗的囊胚移植周期中,利用富血小板血浆(Platelet-Rich Plasma,PRP)和粒细胞集落刺激因子(Granulocyte Colony-Stimulating Factor,G-CSF)进行宫腔内灌注治疗,比较两种治疗方式对改善薄型子宫内膜患者的内膜厚度和冻融复苏移植(Frozen-Thawed Embryo Transfer,ET)周期囊胚移植后的妊娠结局的效果,妊娠结局包括提高胚胎着床率、妊娠率、持续妊娠率、活产率和流产率。  

Objectives of Study:

The English translation of your text is as follows: In blastocyst transfer cycles of in vitro fertilization and embryo transfer (IVF-ET) treatment, intrauterine perfusion therapy is administered using Platelet-Rich Plasma (PRP) and Granulocyte Colony-Stimulating Factor (G-CSF). This study compares the effects of these two treatment methods on improving endometrial thickness and pregnancy outcomes following frozen-thawed embryo transfer (ET) in patients with thin endometrium. The pregnancy outcomes include implantation rate, clinical pregnancy rate, ongoing pregnancy rate, live birth rate, and miscarriage rate.

盲法:

本试验拟采用三盲的试验方法进行,即对测量内膜和决定移植时机的临床观察者、受试者、数据处理者设盲,直至出现主要终点事件或试验结束后再对临床观察者和受试者揭盲,完成数据分析后对数据分析者揭盲。不论研究组还是对照组,均进行单囊胚移植。PRP组在促排和内膜准备过程中进行2次宫腔内PRP灌注,G-CSF组患者在促排和内膜准备过程中进行2次宫腔内G-CSF灌注,对照组在促排和内膜准备过程中进行2次宫腔假灌注。

Blinding:

This study will adopt a triple-blind design, in which the clinical observers responsible for assessing endometrial development and determining the timing of embryo transfer, the participants (subjects), and the data analysts are all blinded. Unblinding for the clinical observers and participants will occur only after the occurrence of the primary endpoint or at the end of the trial, while unblinding for the data analysts will take place after completion of the data analysis. Regardless of whether they are assigned to the treatment group or the control group, all participants will undergo single blastocyst transfer. Patients in the PRP group will receive two intrauterine infusions of platelet-rich plasma (PRP) during ovarian stimulation and endometrial preparation. Patients in the G-CSF group will receive two intrauterine infusions of granulocyte colony-stimulating factor (G-CSF) during the same period. Patients in the control group will undergo two sham intrauterine infusions during ovarian stimulation and endometrial preparation.

本研究的数据录入将在临床数据收集过程中同步进行。数据录入过程中所发现的问题将采用质询表的形式书面通知研究者,由研究者进行审核,并将对质询的答复尽快用书面方式反馈回数据录入/审核人员。书面反馈记录将跟病例报告表一起保存,作为数据修改的依据。对所有经筛选合格而进入本试验并签署了知情同意书的受试者,均须认真、详细记录病例报告表中的所有项目,不得遗漏。完成的病例报告表未经发起单位书面同意,不得以任何形式提供给第三者。病理报告表的电子形式将填写在ResMan网站的EDC系统中。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data entry for this study will be conducted concurrently with clinical data collection. Any issues identified during the data entry process will be communicated to the investigator in writing through query forms. The investigator will review the queries and provide a written response as soon as possible to the data entry/cleaning staff. Written response records will be retained together with the Case Report Forms (CRFs) as documentation supporting any data modifications. For all subjects who have been screened, enrolled in the study, and signed the informed consent form, all items in the CRF must be carefully and completely documented without omission. Completed CRFs shall not be disclosed or provided to any third party in any form without prior written approval from the sponsor of the study. Electronic versions of the CRFs will be completed on the EDC system of the ResMan website.
