IntroductionRecombinant human luteinizing hormone (r-hLH) is used in a fixed-ratio combination with recombinant human follicle-stimulating hormone (r-hFSH) for the stimulation of follicular development.ObjectiveThe objective of this article was to conduct a review of safety data to evaluate the risks of r-hFSH/r-hLH treatment.MethodsData were retrieved from the Global Safety Database (Merck KGaA, Darmstadt, Germany) including reports from healthcare professionals, patients, health authorities, clinical trials, non-interventional studies, and the literature. Reports of important risks (identified and potential) as per the risk management plan applicable at the time of data retrieval were obtained up to December 2017. The estimated patient exposure to r-hFSH/r-hLH in the post-marketing setting was 427,012 treatment cycles. Nine hundred patients received r-hFSH/r-hLH during company-sponsored clinical trials (pre- and post-marketing).ResultsWe identified 72 case reports describing important risks related to r-hFSH/r-hLH use, including 46 cases of ovarian hyperstimulation syndrome (10.8 per 100,000 treatment cycles) and 24 of hypersensitivity reaction (5.6 per 100,000 treatment cycles). No thromboembolic events were reported. One congenital anomaly, not suspected to be related to r-hFSH/r-hLH use, was reported during a clinical trial; the event was resolved by corrective surgery. Two fatal cases were identified; one case of recurrent malignant melanoma (suspected to be related to r-hFSH/r-hLH use) and one case resulting from complications of ovarian hyperstimulation syndrome.ConclusionCumulative reporting rates of important identified and potential risks of r-hFSH/r-hLH during a 10-year surveillance period demonstrate the benefit–risk balance is positive. This post-marketing surveillance and continued surveillance of safety events should provide reassurance about the use of r-hFSH/r-hLH in clinical practice.Electronic supplementary materialThe online version of this article (10.1007/s40264-018-0742-3) contains supplementary material, which is available to authorized users.

Background Ovarian stimulation during medically assisted reproduction treatment should be individualized to optimize outcomes and reduce complications. This study assessed whether use of the recombinant human follicle-stimulating hormone (r-hFSH) pen injector allowing small 12.5 IU dose increments resulted in lower r-hFSH dose per oocyte retrieved in a subgroup of patients at risk of OHSS, compared with r-hFSH injection devices allowing only 37.5 IU increments. Methods This multicenter, comparative, observational study evaluated patients from a prospective (study group) and historical (control group) cohort. The study group enrolled 1783 patients using the redesigned r-hFSH pen injector (GONAL-f®, Merck Healthcare KGaA, Darmstadt, Germany) from a prospective phase IV, non-interventional, open-label study, conducted in Korea, Vietnam, Indonesia, and China. The control group consisted of 1419 patients from a historical study using r-hFSH devices allowing 37.5 IU increments. In the study group, 397 patients were considered at risk of OHSS; this information was unavailable for the control group, so biomarkers and patient characteristics were used to match 123 patients from the study group and control group. Each center adhered to standard practice; starting dose and intra-cycle dose adjustments were allowed at any point. The primary endpoint, amount of r-hFSH (IU) administered per oocyte retrieved, was assessed in matched patients only. Additional outcomes and safety were assessed in the overall populations. Results Baseline characteristics were comparable between groups. Mean (SD) total dose of r-hFSH administered per oocyte retrieved in patients at risk of OHSS, was significantly lower in the study group compared with the control group (132.5 [85.2] vs. 332.7 [371.6] IU, P < 0.0001, n = 123). Implantation rate, clinical pregnancy rate, and live birth rates in the overall study and control groups were 30.0 vs. 20.6%, 50.3 vs. 40.7%, and 43.8 vs. 34.0%, respectively. OHSS incidence was significantly lower in the study group compared with the control group (27/1783 [1.5%] vs. 57/1419 [4.0%] patients, P < 0.0001). AEs were reported by 5.0% of patients in the study group. Conclusions A significantly lower r-hFSH dose per oocyte retrieved and lower OHSS incidence were observed in patients using the redesigned injector compared with patients using other injection devices.

Globally, more than 200 million women become pregnant each year, most of whom receive medications despite limited information on their safe use during pregnancy. The paucity of drug safety data on pregnant and breastfeeding women stems from the routine exclusion of this population from clinical trials due to scientific, ethical, regulatory and legal concerns. Consequently, at the time of initial drug approval, there may be scant safety data to inform the drug benefit-risk balance to the mother, foetus, or infant. Although momentum is growing to include this underrepresented population in clinical trials, most information on drug exposure outcomes comes from data collected in the post-marketing setting. Regulatory guidance and legislation on medication use in pregnancy and breastfeeding were reviewed globally by TransCelerate IGR PV Pregnancy and Breastfeeding Team. ICH standards and CIOMS guidelines served as benchmarks for national safety regulations and guidance. The landscape assessment identified a lack of harmonisation of global regulations on research in pregnant and breastfeeding women. This editorial focuses on the ambiguities and lack of harmonisation in global regulations on post-marketing pregnancy and breastfeeding safety studies. There is currently no ICH standard to guide these types of safety studies and, in most regions reviewed, there are no clear regulations or guidance on when and how to conduct them. While a challenging undertaking, greater clarity and harmonisation would facilitate more timely completion of post-marketing pregnancy safety studies that would ultimately generate the critical data needed to optimize benefit-risk decisions for pregnant and breastfeeding women.
