Asherman's Syndrome | Biological: hAECs Biological: biological amnion | Phase 1 |
Asherman's syndrome is a gynecological disorder caused by the destruction of the endometrium due to repeated or aggressive curettages and/or endometritis. As a result, there is a loss of functional endometrium in multiple areas and the uterine cavity is obliterated by intrauterine adhesions, which results in amenorrhea, hypomenorrhea, infertility and recurrent pregnancy loss. Transcervical resection of adhesion (TCRA) is the main treatment for Asherman's syndrome, so far the effect is usually poor in moderate to severe refractory cases.
Human amniotic epithelial cells (hAECs) are derived from human amniotic epithelium. hAECs retain the characteristics approximating to embryonic stem cells. Animal experiments have shown that the endometrial thickness and fertility of mice were significantly improved after intrauterine therapy with amniotic epithelial cells. To further explore the role of hAECs in Asherman's syndrome patients, this project plans to evaluate the safety of hAECs provided by Chongqing iCELL Biotechnology Co.,Ltd., which is a subsidiary of Shanghai iCELL Biotechnology Co.,Ltd., and find an effective treatment protocol.

Arm | Intervention/treatment |
---|---|
Experimental: biological amnion loaded with hAECs
Biological amnion loaded with 100 million hAECs is placed into uterine cavity immediately after TCRA.
|
Biological: hAECs
hAECs are provided by Chongqing iCELL Biotechnology Co.,Ltd., which is a subsidiary of Shanghai iCELL Biotechnology Co.,Ltd. The participants are blind to their arms because the surgery is done under anesthesia. After hysteroscopic adhesiolysis, subsequently oral antibiotics will be given for 3 days to prevent infection. Estrogen will be administrated for 3 cycles to stimulate the repair of endometrium after the surgery. |
Placebo Comparator: biological amnion
Biological amnion is placed into uterine cavity immediately after TCRA.
|
Biological: biological amnion
Biological amnion is purchased from JiangXi RuiJi BioTechnology Co.,Ltd. The participants are blind to their arms because the surgery is done under anesthesia. After hysteroscopic adhesiolysis, subsequently oral antibiotics will be given for 3 days to prevent infection. Estrogen will be administrated for 3 cycles to stimulate the repair of endometrium after the surgery. |
Experimental: intravenous infusion of hAECs
intravenous infusion of 100 million hAECs immediately after TCRA
|
Biological: hAECs
hAECs are provided by Chongqing iCELL Biotechnology Co.,Ltd., which is a subsidiary of Shanghai iCELL Biotechnology Co.,Ltd. The participants are blind to their arms because the surgery is done under anesthesia. After hysteroscopic adhesiolysis, subsequently oral antibiotics will be given for 3 days to prevent infection. Estrogen will be administrated for 3 cycles to stimulate the repair of endometrium after the surgery. |
Experimental: intrauterine infusion of hAECs
100 million hAECs is infused into uterine cavity immediately after TCRA.
|
Biological: hAECs
hAECs are provided by Chongqing iCELL Biotechnology Co.,Ltd., which is a subsidiary of Shanghai iCELL Biotechnology Co.,Ltd. The participants are blind to their arms because the surgery is done under anesthesia. After hysteroscopic adhesiolysis, subsequently oral antibiotics will be given for 3 days to prevent infection. Estrogen will be administrated for 3 cycles to stimulate the repair of endometrium after the surgery. |
Experimental: hydrogel loaded with hAECs
Hydrogel loaded with 100 million hAECs is infused into uterine cavity immediately after TCRA.
|
Biological: hAECs
hAECs are provided by Chongqing iCELL Biotechnology Co.,Ltd., which is a subsidiary of Shanghai iCELL Biotechnology Co.,Ltd. The participants are blind to their arms because the surgery is done under anesthesia. After hysteroscopic adhesiolysis, subsequently oral antibiotics will be given for 3 days to prevent infection. Estrogen will be administrated for 3 cycles to stimulate the repair of endometrium after the surgery. |
- Menstrual blood volume [ Time Frame: at 3 months ]Estimate the menstrual blood volume after surgery by the number of sanitary napkins per day and number of days, which will be compared with pre-operation.
- Endometrial thickness [ Time Frame: at 3 months ]Measure the endometrial thickness during periovulatory period on ultrasound by the same trained medical sonographers at 3 months after surgery, compared with pre-operation.
- Uterine volume [ Time Frame: at 3 months ]Measure the uterine volume during periovulatory period on ultrasound by the same trained medical sonographers at 3 months after surgery, compared with pre-operation.
- Ongoing pregnancy rate [ Time Frame: up to 24 months ]A ongoing pregnancy means that at the 12th week of pregnancy, ultrasound reveals that the fetus had a heart beat and the size of the fetus is in consistent with the gestational week.
