Cumulative Live Birth Rates Following Stimulation With Corifollitropin Alfa Compared With hp-hMG in a GnRH Antagonist Protocol in Poor Ovarian Responders.

ABSTRACT: Background: Bologna criteria poor ovarian responders have a very low prognosis. Although, it has been proposed that LH supplementation could be beneficial in women with previous hypo-response to FSH. There are no studies comparing the cumulative live birth rates (LBRs) between corifollitropin alfa (CFA) and highly purified human menopausal gonadotrophin (hp-hMG). Objective: To compare cumulative LBRs in Bologna poor ovarian responders undergoing ovarian stimulation with CFA followed by hp-hMG vs. hp-hMG alone in a GnRH antagonist protocol. Design: This is a retrospective cohort study. We included in total 917 poor responders fulfilling the Bologna criteria for poor ovarian response (POR) at a university-affiliated tertiary center from January 2011 until March 2017. Patients were administered either fixed daily doses of 300-450 IU of hp-hMG (group A) or a single dose of 150 ?g of CFA followed by daily injections of ?300 IU of hp-hMG from Day 8 of stimulation until the day of ovulation trigger (group B), in a fixed GnRH antagonist protocol. Results: LBRs after fresh embryo transfer (ET) were similar in group A 71/510 (14%) and B 42/407 (10%). Cumulative LBR per cycle was significantly higher in group A (16.9%) compared to group B (11.8%); (P = 0.03). However, logistic regression analysis showed no association between the type of gonadotropin administered and cumulative LBR. Only age was significantly associated with cumulative LBR (OR = 0.93, P = 0.007). Conclusion: Cumulative LBRs are similar in Bologna poor responders stimulated with CFA followed by hp-hMG compared to hp-hMG monotreatment in an antagonist protocol.

Project description:STUDY QUESTION:What is the threshold for the prediction of moderate to severe or severe ovarian hyperstimulation syndrome (OHSS) based on the number of growing follicles ? 11 mm and/or estradiol (E2) levels? SUMMARY ANSWER:The optimal threshold of follicles ?11 mm on the day of hCG to identify those at risk was 19 for both moderate to severe OHSS and for severe OHSS. Estradiol (E2) levels were less prognostic of OHSS than the number of follicles ? 11 mm. WHAT IS KNOWN ALREADY:In comparison to long gonadotropin-releasing hormone (GnRH) agonist protocols, the risk of severe OHSS is reduced by approximately 50% in a GnRH antagonist protocol for ovarian stimulation prior to in vitro fertilisation (IVF), while the two protocols provide equal chances of pregnancy per initiated cycle. Nevertheless, moderate to severe OHSS may still occur in GnRH antagonist protocols if human chorionic gonadotropin (hCG) is administered to trigger final oocyte maturation, especially in high responder patients. Severe OHSS following hCG trigger may occur with an incidence of 1-2% in a relatively young (aged 18 to 36 years) IVF population treated in a GnRH-antagonist protocol. STUDY DESIGN, SIZE, DURATION:From the Engage, Ensure and Trust trials, in total, 2,433 women who received hCG for oocyte maturation and for whom the number of follicles ? 11 mm and the level of E2 on the day of hCG administration were known were included in the analyses. PARTICIPANTS/MATERIALS, SETTING, METHODS:The threshold for OHSS prediction of moderate and severe OHSS was assessed in women treated with corifollitropin alfa or daily recombinant follicle stimulation hormone (rFSH) in a gonadotropin-releasing hormone (GnRH)-antagonist protocol. Receiver operating characteristics curve analyses for moderate to severe OHSS and severe OHSS were performed on the combined dataset and the sensitivity and specificity for the optimal threshold of number of follicles ? 11 mm, E2 levels on the day of (hCG), and a combination of both, were determined. MAIN RESULTS AND THE ROLE OF CHANCE:The optimal threshold of follicles ? 11 mm on the day of hCG to identify those at risk of moderate to severe OHSS was 19 (sensitivity and specificity 62.3% and 75.6%, respectively) and for severe OHSS was also 19 (sensitivity and specificity 74.3% and 75.3%, respectively). The positive and negative predictive values were 6.9% and 98.6%, respectively, for moderate to severe OHSS, and 4.2% and 99.5% for severe OHSS. LIMITATIONS, REASONS FOR CAUTION:This was a retrospective analysis of combined data from three trials following ovarian stimulation with two different gonadotropins. WIDER IMPLICATIONS OF THE FINDINGS:For patients with 19 follicles or more ?11 mm on the day of hCG, measures to prevent the development of OHSS should be considered. Secondary preventive measures include cycle cancellation or coasting, use of a GnRH agonist to trigger final oocyte maturation in place of hCG and a freeze all strategy.

Project description:Utilizing corifollitropin alfa in GnRH antagonist (GnRHant) protocol in conjunction with GnRH agonist trigger/freeze-all strategy (corifollitropin alfa/GnRHant protocol) was reported to have satisfactory outcomes in women with polycystic ovary syndrome (PCOS). Although lessening in gonadotropin injections, GnRHant were still needed. In addition to using corifollitropin alfa, GnRHant was replaced with an oral progestin as in progestin primed ovarian stimulation (PPOS) to further reduce the injection burden in this study. We try to investigate whether this regimen (corifollitropin alfa/PPOS protocol) could effectively reduce GnRHant injections and prevent premature LH surge in PCOS patients undergoing IVF/ICSI cycles. This is a retrospective cohort study recruiting 333 women with PCOS, with body weight between 50 and 70 kg, undergoing first IVF/ICSI cycle between August 2015 and July 2018. We used corifollitropin alfa/GnRHant protocol prior to Jan 2017 (n = 160), then changed to corifollitropin alfa/PPOS protocol (n = 173). All patients received corifollitropin alfa 100 μg on menstruation day 2/3 (S1). Additional rFSH was administered daily from S8. In corifollitropin alfa/GnRHant group, cetrorelix 0.25 mg/day was administered from S5 till the trigger day. In corifollitropin alfa/PPOS group, dydrogesterone 20 mg/day was given from S1 till the trigger day. GnRH agonist was used to trigger maturation of oocyte. All good quality day 5/6 embryos were frozen, and frozen-thawed embryo transfer (FET) was performed on subsequent cycle. A comparison of clinical outcomes was made between the two protocols. The primary endpoint was the incidence of premature LH surge and none of the patients occurred. Dydrogesterone successfully replace GnRHant to block LH surge while an average of 6.8 days of GnRHant injections were needed in the corifollitropin alfa/GnRHant group. No patients suffered from ovarian hyperstimulation syndrome (OHSS). The other clinical outcomes including additional duration/dose of daily gonadotropin administration, number of oocytes retrieved, and fertilization rate were similar between the two groups. The implantation rate, clinical pregnancy rate, and live birth rate in the first FET cycle were also similar between the two groups. In women with PCOS undergoing IVF/ICSI treatment, corifollitropin alfa/PPOS protocol could minimize the injections burden with comparable outcomes to corifollitropin alfa/GnRHant protocol.

Project description:Study questionIn women undergoing IVF or ICSI cycles, do recombinant gonadotrophins differ from urinary-derived highly purified human menopausal gonadotropin (HP-hMG) or highly purified follicle-stimulating hormone (HP-FSH) in the total amount of gonadotrophins required to reach a live birth?Summary answerThe difference between recombinant and urinary-derived HP-hMG or HP-FSH in the required amount to reach a live birth in IVF/ICSI cycles appears small.What is known alreadyAt present, gynecologists can choose between recombinant FSH (rFSH), urinary-derived HP-hMG and HP-FSH. These products are equally effective and safe, but it is unknown how these gonadotrophins compare in terms of IU required to reach a live birth.Study design size and durationWe conducted a search in Medline, Embase and CINAHL up to July 2018. We included randomized controlled trials (RCTs) that compared rFSH with HP-hMG or HP-FSH for ovarian stimulation in couples scheduled for IVF or ICSI treatment. From each randomized trial, we extracted the outcome data and information on participants, methods, interventions and funding.Participants/materials setting and methodsWomen undergoing ovarian stimulation with rFSH, HP-hMG or HP-FSH were included. We extracted data for the mean amount of gonadotrophins with SD, clinical pregnancy rate, live birth rate and cumulative live birth rate per woman from the included RCTs. We summarized these outcomes by calculating the individual and pooled mean difference (MD) or relative risk (RR) with 95% CI. We used the Review Manager software to perform the meta-analyses. We applied a random effect model to pool the data. We estimated the total amount of gonadotrophins used per extra live birth by STATA 14.2 and R software.Main results and the role of chanceA total of 28 studies with 7553 women were included in this review, of which 24 studies provided information on the total amount of gonadotrophins per woman who started an IVF/ICSI cycle. The total amount of gonadotrophins varied significantly between studies. The MDs in total amount were -37 IU (seven studies; N = 3220; 95% CI, -115 to 41; I 2 = 68%) for rFSH versus HP-hMG and -31 IU (17 studies; N = 3629; 95% CI, -290 to 228; I 2 = 97%) for rFSH versus HP-FSH. For rFSH versus HP-hMG, the RR for clinical pregnancy, live birth and cumulative live birth were 0.90 (95% CI, 0.81-1.00), 0.88 (95% CI, 0.78-0.99) and 0.91 (95% CI, 0.80-1.04), respectively. For rFSH versus HP-FSH, the RR for clinical pregnancy and live birth were 1.03 (95% CI, 0.94-1.13) and 1.03 (95% CI, 0.90-1.18), respectively; the data on cumulative live birth rate were lacking. The estimated difference in mean gonadotrophin amount per extra live birth was 789 IU (95% CI, -9.5 to 1570) for rFSH versus HP-hMG and -365 IU (95% CI, -2675 to 1945) for rFSH versus HP-FSH.Limitations reasons for cautionThere was severe heterogeneity in the total amount of gonadotrophins between studies. A small fraction of women did not start gonadotrophin treatment; this was usually not accounted for in the provided mean amount of gonadotrophins per study and might have affected the averaged total amount of gonadotrophins but is unlikely to have affected the differences in the amount between rFSH and HP-hMG or HP-FSH.Wider implications of the findingsThe differences in the required amount to reach a live birth between rFSH, HP-hMG and HP-FSH appear to be small. Decision-making should be based on convenience, availability, actual costs and patient preferences.Study funding/competing interestsThe authors declare no conflict of interest. No external funding was either sought or obtained for this study.Registration numberProspero CRD42016038238.

Project description:BackgroundA consensus has been reached on the preferred primary outcome of all infertility treatment trials, which is the cumulative live birth rate (CLBR). Some recent randomized controlled trials (RCTs) and retrospective studies have compared the effectiveness of GnRH-antagonist and GnRH-agonist protocols but showed inconsistent results. Studies commonly used conservative estimates and optimal estimates to described the CLBR of one incomplete assisted reproductive technology (ART) cycle and there are not many previous studies with data of the complete cycle to compare CLBRs in GnRH-antagonist versus GnRH-agonist protocols.MethodsA total of 18,853 patients have completed their first IVF cycle including fresh and subsequent frozen-thawed cycles during 2016-2019, 16,827 patients were treated with GnRH-a long and 2026 patients with GnRH-ant protocol. Multivariable logistic analysis was used to evaluate the difference of GnRH-a and GnRH-ant protocol in relation to CLBR. Utilized Propensity Score Matching(PSM) for sampling by up to 1:1 nearest neighbor matching to adjust the numerical difference and balance the confounders between groups.ResultsBefore PSM, significant differences were observed in baseline characteristics and the CLBR was 50.91% in the GnRH-a and 33.42% in the GnRH-ant (OR = 2.07; 95%CI: 1.88-2.28; P < 0.001). Stratified analysis showed the CLBR of GnRH-ant was lower than GnRH-a in suboptimal responders(46.89 vs 27.42%, OR = 2.34, 95%CI = 1.99-2.74; P < 0.001) and no differences of CLBR were observed in other patients between protocols. After adjusting for potential confounders, multivariable logistic analysis found the CLBR of GnRH-ant group was lower than that of GnRH-a group (OR = 2.11, 95%CI:1.69-2.63, P < 0.001). After PSM balenced the confounders between groups, the CLBR of GnRH-a group was higher than that of GnRH-ant group in suboptimal responders((38.61 vs 28.22%, OR = 1.60, 95%CI = 1.28-1.99; P < 0.001) and the normal fertilization rate and number of available embryo in GnRH-a were higher than these of GnRH-ant groups in suboptimal responders (77.39 vs 75.22%; 2.86 ± 1.26 vs 2.61 ± 1.22; P < 0.05). No significant difference was observed in other patients between different protocols.ConclusionsIt is crucial to optimize the utilization of protocols in different ovarian response patients and reconsider the field of application of GnRH-ant protocols in China.
