研究目的: |
评估乳杆菌阴道移植(Vaginal Microbiota Transplantation, VMT)对绝经前乳腺癌患者在接受卵巢功能抑制联合芳香化酶抑制剂(OFS+AI)内分泌治疗后发生的生殖泌尿系统综合征(Genitourinary Syndrome of Menopause, GSM)的疗效及安全性。主要评价治疗后3个月阴道微生态恢复率(包括Nugent评分、乳杆菌浓度、阴道pH值及症状VAS评分),并进一步评估女性性功能指数(FSFI)、乳腺癌内分泌症状量表(FACT‑ES)及阴道健康指数(VHI)等指标的变化。 |

Objectives of Study: |
To evaluate the efficacy and safety of vaginal microbiota transplantation (VMT) for the treatment of genitourinary syndrome of menopause (GSM) in premenopausal breast cancer patients receiving ovarian function suppression plus aromatase inhibitor (OFS+AI) endocrine therapy. The primary objective is to assess the vaginal microbiota restoration rate at 3 months after treatment, including Nugent score, Lactobacillus concentration, vaginal pH, and symptom VAS score. Secondary outcomes include changes in Female Sexual Function Index (FSFI), Functional Assessment of Cancer Therapy-Endocrine Symptoms (FACT‑ES), and Vaginal Health Index (VHI). |

Presence of a definitely diagnosed active vaginal infection, including any of the following, at the screening visit: (1) Bacterial vaginosis (BV): At least three clinical diagnoses meet Amsel criteria, or a Nugent score of 7-10 for vaginal discharge. (2) Vulvovaginal candidiasis (VVC): with typical clinical symptoms, and vaginal secretions are found to be pseudohyphae or spores of Candida or positive fungal culture. (3) Trichomoniasis vaginitis: Vaginal secretions wet film microscopic examination found Trichomonas vaginalisis, or positive pathogen nucleic acid test. (4) Aerobic vaginitis (AV): According to the Donders standard, the comprehensive score based on wet film microscopy of vaginal secretions >=3 points. 2. Have a severe immunodeficiency disease, including but not limited to: (1) Human immunodeficiency virus (HIV) infected. (2) Patients who are receiving high-dose, systemic immunosuppressive therapy (defined as: continuous use of prednisone>=20mg/day or equivalent dose of other immunosuppressants for more than 2 weeks within 4 weeks prior to study screening). (3) Other known primary or secondary immunodeficiency diseases. 3. Received systemic (oral or intravenous) antibiotic therapy for any reason within 1 month prior to the start of study intervention. 4. Current use of systemic hormone therapy that may significantly affect the vaginal microbiome, including estrogen, progestogen, or glucocorticoids in oral, injectable, or patch form. Note: For patients on long-term (>3 months) and stable use of low-dose topical estrogen (e.g., estriol cream) for the treatment of urogenital atrophy, it is not an exclusion criterion if the dose remains unchanged during the study, but it needs to be documented in detail in the case report form. 5. Known or suspected history of allergy to any active ingredient (such as Lactobacillus) or excipients (such as milk product ingredients) in the investigational product. 6. Participated in any other interventional clinical study within 3 months before screening. 7. Subject has any medical, psychological, or social condition that may affect his completion of the study, or poor compliance, according to the judgment of the investigator. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
本研究的数据采集与管理包括病例报告表(Case Report Form,CRF)和电子数据采集系统(Electronic Data Capture,EDC)两部分。研究过程中所有临床数据首先记录于标准化病例报告表(CRF),包括受试者人口学信息、病史资料、研究终点指标、不良事件及实验室检查结果等。随后由经过培训的研究人员将数据录入电子病例报告表(eCRF)系统进行统一管理。 本研究采用基于互联网的电子数据采集系统(EDC)进行数据管理,对录入数据进行逻辑校验与自动核查,以减少录入错误。对于系统提示的疑问数据,将进行回溯核实并及时更正。研究期间每月开展数据完整性检查,并定期抽样10%的病例进行源数据核查(Source Data Verification,SDV),要求数据一致性达到95%以上。所有数据均采用匿名编码方式保存,并严格控制访问权限,以确保数据的安全性和保密性。研究结束后按照预先制定的数据清理和数据库锁定标准操作程序(SOP)完成数据锁定,形成最终分析数据集用于统计分析。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection and management in this study consist of two components: Case Report Forms (CRFs) and an Electronic Data Capture (EDC) system. All clinical data will first be recorded in standardized CRFs, including demographic characteristics, medical history, study endpoints, adverse events, and laboratory test results. Trained research staff will subsequently enter the data into an electronic case report form (eCRF) for centralized management. A web‑based Electronic Data Capture (EDC) system will be used to manage study data. The system performs logical checks and automatic validation to minimize data entry errors. Any data queries generated by the system will be reviewed and verified through source documents and corrected when necessary. During the study, monthly data completeness checks will be conducted, and approximately 10% of cases will undergo source data verification (SDV) to ensure a data consistency rate of at least 95%. All participant information will be stored using anonymized codes, and access to the database will be restricted to authorized personnel to ensure data security and confidentiality. After completion of the study, data cleaning and database lock will be performed according to predefined standard operating procedures (SOPs), and the final dataset will be used for statistical analysis. |
