The underlying cause of RPL is most often unknown, probably multifactorial, and no treatment with documented effect on chance of live birth exists. In unexplained cases of RPL, primarily the immune system is hypothesized to play a pivotal, causative role, since autoantibodies and specific human leukocyte antigen (HLA) alleles as well as unbalanced distribution of leucocyte subsets, especially natural killer (NK) cells and T-helper (Th) cells, occurs more frequently in patients with unexplained RPL. For that reason, many treatment regimens used in autoimmune diseases have been tested on RPL patients, as for example prednisolone and intravenous immunoglobulin (IVIg).\n\nIVIg (Privigen) consist of a broad spectrum of structurally and functionally intact IgG antibodies. The mechanism of action is not fully elucidated, but certainly IVIg do help opsonise and neutralize foreign cells and pathogens. Prednisolone support this anti-inflammatory action by suppressing migration of polymorphonuclear leukocytes, and reducing the volume and activity of the immune system and the capillary permeability.\n\nA retrospective, observational pilot study suggested that a combination of prednisone and IVIg in first trimester improves the chance of a live birth in women with RPL after assisted reproductive technologies (ART) (Nyborg et al., 2014).\n\nA randomized controlled study is necessary for determining if this immunomodulatory treatment definitely is effective in patients with unexplained RPL after ART (defined as IVF or ICSI ad FER). Potentially, this study will be able to establish evidence for an effective treatment to women with unexplained RPL after ART, who otherwise have a poor prognosis.', 'detailedDescription': "In a randomized, double-blinded, placebo-controlled trial, this study aims to investigate whether treatment with prednisolone and intravenous immunoglobulin (IVIg) before and in early pregnancy improves the chance of a live birth in women undergoing treatment with artificial reproductive technologies (ART) (defined as IVF or ICSI or FER treatment) after previous recurrent pregnancy loss (RPL) after ART.\n\nIf an improved live birth rate can be confirmed, the treatment will be the first documented treatment supplement for women with RPL undergoing ART treatment. A treatment with such effect is highly desirable. If the treatment increases the birth rate, it will potentially also improve quality of life and reduce detrimental anxiety and stress symptoms associated with RPL and ART treatment, since the burden (including the number of treatments and the number of losses) will be reduced.\n\nPotential study participants will be identified among patients who are referred to The Center for Recurrent Pregnancy Loss of Western Denmark (in the following called The RPL Center), located at Aalborg University Hospital (AaUH) Denmark.\n\nAt the first appointment at The RPL Center, a list of standard health information important for the RPL examination will be collected together with the RPL Center's standard blood sample.\n\nTreatment: The participants will be randomly allocated 1:1 to active immunomodulatory treatment versus placebo treatment (see Arms and Interventions). Study treatment starts on the patient's first day of her menstrual cycle in which her fertility clinic plan to transfer an embryo/blastocyst(s) and continue until a negative pregnancy test, the time of biochemical pregnancy loss/miscarriage or pregnancy week 8+0, whichever comes first.\n\nfrom first day of cycle and until embryo transfer, one tablet (5mg prednisolone or placebo) per day is taken. First infusion (IVIg or Albumin) is given within 5 workings days before and 2 working days after embryo transfer. On the day of embryo transfer, two tablet per day is taken.\n\nApproximately 14 days after ET, the patient will have a pregnancy test. If positive, the patient will have plasma-hCG measured twice with 1-2 days interval at her local hospital. With adequate increment of plasma-hCG, the patient will be booked for her last 3 infusions in gestational week 5, 6, and 7, and continue tablet intake. If she is not pregnant, study medication will not continue.\n\nOn the day of the first infusion treatment and again approximately four weeks later (the day of her third infusion treatment during pregnancy), a study specific blood sample will be taken for our research biobank. In participants who do not achieve pregnancy or have a miscarriage before gestational week 6 (and therefore do not come for the third infusion), we will ask these participants to come for the second blood sample too. The blood samples will be analysed by the Department of Clinical Immunology at AaUH.\n\nIn addition, in a separate study performed by the same investigators, a group of 37 healthy females in reproductive age with no prior known pregnancy losses will have one blood sample collected in their luteal phase and analyzed according to the same protocol and will serve as a reference group to the two study groups.\n\nAn immediate analysis of the blood sample will quantify NK-cells, B-cells, and T-cell subsets by flow cytometry. Also, a TruCulture analysis for activity of leucocyte subsets will be carried out in 25 patients. The research/future biobank will store frozen serum and plasma for analysis of immune markers including smaller extracellular vesicles.\n\nIf the participant is still pregnant after her last infusion of study medicine before week 8+0, she will be offered routine monitoring at The RPL Center at AaUH, at her local fertility clinic, and her local hospital. She will receive a questionnaire 2 weeks after her nuchal scan and 2 weeks after her due date for collection of data regarding her pregnancy, delivery, and perinatal outcome.\n\nStudy-relevant data will be collected from medical records, birth records, questionnaires, and the research biobank.\n\nAdverse events will be recorded on all participants from the day of admission and until 6 months after last infusion treatment or until birth of her child if she becomes pregnant. Both adverse events in the participant and her child will be recorded. To support compliance and meticulous reporting of side effects, all participants receive a folder with a list of all known side effects to prednisolone, IVIg and albumin, a diary with boxes to tick of every day the tablet(s) is taken, and a table in which side effects can continuously be noted. According to the child, negative perinatal outcomes (e.g., low birth weight, preterm birth, stillbirth) and malformations will be recorded after birth."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT'], 'maximumAge': '41 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Women with ≥ 2 consecutive pregnancy losses (miscarriages or biochemical pregnancies) ≤ completed gestational week 10 after ART with the present partner or with an egg/semen donor\\*\n\n * The gestational week of the non-induced pregnancy losses will be based on the date of clinical signs of miscarriage or the fetus' crown-rump-length of a missed abortion measured on the ultrasonic scan detecting the pregnancy loss.
