Uterine Transplantation and Pregnancy Induction in Women Affected by Absolute Uterine Infertility

Study Overview
=================
Brief Summary
-----------------
This study aims to investigate the treatment of absolute uterine infertility (AUI) due to congenital or surgical absence of a uterus or presence of a nonfunctioning uterus. The investigators will follow a model based on a Swedish study to enroll 20 women with functioning ovaries and successfully transplant the uterus from either a living or cadaveric donor, with the goal of live birth after transplantation.

Detailed Description
-----------------
INTRODUCTION Absolute Uterine Factor Infertility (AUI) is due to congenital or surgical absence of a uterus or presence of a nonfunctional uterus. Until 2014 the only option for women affected by Absolute Uterine Factor Infertility (AUI) was adoption or surrogate motherhood. Primary Objective Successful living or deceased donor uterine transplants resulting in live birth. Pregnancy rate via in vitro fertilization. BACKGROUND In 1991 the National Transplantation Pregnancy Registry (NTPR) was established to study the outcomes of female transplant recipients. In 2010 the NTPR had collected data on 2000 pregnancy outcomes. The NTRP database includes data not just on the pregnancy but on follow-up of both parents and their offspring. The first reported case of pregnancy after transplant was reported in 1958. In 2011 25,787 solid organ transplant recipients (kidney, liver, pancreas, small bowel, heart & lung) of which: 9662 were women 3505 were of childbearing age 765 were less than 17 years old and could potentially become pregnant later in life. One of the benefits of receiving a kidney, liver, pancreas, small bowel, heart or lung transplant is the underlying disease that caused the subject to have a transplant is gone, therefore fertility returns. Pregnancy after transplant is increasingly common. This has led to an accumulation of data and knowledge on how to best manage this subject population. These pregnancies are still considered high-risk. Successful pregnancy outcomes are a result of transplant and obstetrics teams working closely together. The American Society of Transplantation (AST) recommends for solid organs that pregnancy is allowable if there has been: no rejection within the past year, there is adequate and stable graft function, no acute infections that may impact fetal growth and well-being and maintenance immunosuppression is at stable dosing. Both the NTPR and AST advise waiting one year until after transplant before conceiving. This one year wait time is associated with better maternal and neonatal outcomes and fewer obstetric complications.Based on the long term data from the NPTR on transplant recipient's pregnancy outcomes and the relative safety of immunosuppressive medications a new area of transplant is being developed. Uterine transplant may provide an additional option for women with absolute uterine infertility (AUI). Pre-clinical research into uterine transplant has been going on for more than a decade. There have been several studies demonstrating the feasibility of Uterine Transplantation in animals, both primates and non-primates. In the last year human trials have started in Europe. RATIONALE In Great Britain an estimated 12000 women of childbearing age are affected by AUI. In the US the number of women affected by AUI may be in the millions considering that 9 million women of reproductive age have had a hysterectomy. Congenital absence of the Uterus has been reported in 1/5000 women and in 2005 over 12000 women in reproductive age,15 years to 44 years have been diagnosed with congenital absence of the Uterus. In the US, 1000 hysterectomies are performed immediately post-partum for every 1 million births. It is estimated that 62 million women in the United States are in the reproductive age and about 15.4% may have absolute AUI, and about 7 million women may have lost their uterus to benign causes or obstetric complications. Although the statistics may offer different interpretation it seems evident that thousands of women in the United States may be interested in considering Uterine Transplantation as their best option to have children. Previous Subject Experience There were two reported attempts at uterine transplantation at other institutions, one of which was able to carry two pregnancies but not at term. However, the University of Gothenburg reported the first clinical trial of Uterine Transplantation as nouvelle treatment for AUI. In this report 9 living donors and 9 recipients underwent donor hysterectomies and recipient uterine transplantation. Seven out of the 9 had viable uteri at the time of the report with 1 recipient losing the transplanted uterus to an infection and the other one to a vascular complication. One donor suffered a surgical grade IIIb complication, an ureterovaginal fistula, and was successfully treated. This early report was followed by a subsequent one where the 7 recipients showed regular menses and 5 out of the seven recipient suffered mild rejection episodes that were all successfully treated. The feasibility of Uterine Transplantation as a cure to AUI was finally demonstrated by the first live birth after uterus transplantation. The surgeries have been described by the Gothenburg University Group consist of a total abdominal hysterectomy and upper vaginectomy with preservation of the major feeding arteries and veins to the uterus of the donor and the implantation of the uterus in the pelvis of the recipient. Vascular anastomosis is achieved between the two major arteries and veins of the uterus, extending to the external iliac vessels of the recipient using transplant microvascular techniques. Finally the vaginal rim of the transplanted uterus is anastomosed to the recipient's vaginal vault. The procedure can be performed also with a uterus obtained from a deceased donor. The hysterectomy in the deceased donor will proceed as described above. The advantage will be obtaining the vascular pedicle attached to segments of the iliac artery and vein which will make the implantation in the recipient technically easier. The preservation solution will not change and the ischemia time will be kept under 6 hours. 2. STUDY DESIGN This is a prospective study to treat absolute uterine infertility (AUI) through uterine transplantation resulting in live birth. There will be five distinct clinical stages in the study after inclusion/exclusion met criteria & subject consented: Pre-transplant/Screening, Transplant/Recovery, embryo transfer/Pregnancy, Delivery/Explant, Follow up. Number of Clinical Sites and Subjects This trial will be conducted at the Annette C. and Harold C. Simmons Transplant Institute, Baylor University Medical Center in Dallas, TX. A total of 10 female (biologically) subjects will receive a uterine transplant. Subjects can either receive a uterus from a living donor or a cadaveric donor. Living donors will be consented per the living donor research protocol. Uterus recovery from cadaveric donors will follow UNOS guidelines. SUBJECT PARTICIPATION and STUDY DURATION All subjects will be followed for a 5 year period post-transplant. Continued follow up depends upon the subject status: Subjects who received a uterine transplant resulting in live birth then and have the uterus removed will be followed for 12 months post explant. Subjects who received a uterine transplant resulting in live birth and desire another pregnancy will be followed through the second pregnancy resulting in live birth for 12 months post explant. Subjects who have the uterus explanted due to infection, rejection or unable to maintain pregnancy will be followed for 12 months post explant.
