Core Data Elements for Pregnancy Pharmacovigilance Studies Using Primary Source Data Collection Methods: Recommendations from the IMI ConcePTION Project.

INTRODUCTION AND OBJECTIVE: The risks and benefits of medication use in pregnancy are typically established through post-marketing observational studies. As there is currently no standardised or systematic approach to the post-marketing assessment of medication safety in pregnancy, data generated through pregnancy pharmacovigilance (PregPV) research can be heterogenous and difficult to interpret. The aim of this article is to describe the development of a reference framework of core data elements (CDEs) for collection in primary source PregPV studies that can be used to standardise data collection procedures and, thereby, improve data harmonisation and evidence synthesis capabilities. METHODS: This CDE reference framework was developed within the Innovative Medicines Initiative (IMI) ConcePTION project by experts in pharmacovigilance, pharmacoepidemiology, medical statistics, risk-benefit communication, clinical teratology, reproductive toxicology, genetics, obstetrics, paediatrics, and child psychology. The framework was produced through a scoping review of data collection systems used by established PregPV datasets, followed by extensive discussion and debate around the value, definition, and derivation of each data item identified from these systems. RESULTS: The finalised listing of CDEs comprises 98 individual data elements, arranged into 14 tables of related fields. These data elements are openly available on the European Network of Teratology Information Services (ENTIS) website ( http://www.entis-org.eu/cde ). DISCUSSION: With this set of recommendations, we aim to standardise PregPV primary source data collection processes to improve the speed at which high-quality evidence-based statements can be provided about the safety of medication use in pregnancy.

An alternative to product-specific pregnancy registries? PRIM; PRegnancy outcomes Intensive Monitoring.

Patient safety during pregnancy is an important concern. This article presents a method of using an industry safety database to access prospective pregnancy cases. This method, termed here 'PRegnancy outcomes Intensive Monitoring' (PRIM) was developed for fingolimod (Gilenya ™), a treatment option for multiple sclerosis (MS), due to slow enrollment in the company pregnancy registry. The aim of PRIM was to enhance the process of pregnancy data collection and improve data quality, and in particular to enable estimation of the proportion of major congenital malformation and other pregnancy outcomes. To do this, the spontaneous reports of maternal exposure to fingolimod in pregnancy or in the eight weeks immediately before the last menstrual period of patients not enrolled in the pregnancy registry were identified. Follow up checklists were sent at four time points: initial pregnancy report, end of pregnancy, infant attained 3 and 12 months of age. These focused on core data required for derivation of programmed analyses. From 01 Mar 2014 to 28 Feb 2018, a total of 831 prospective maternal exposures with 843 infants were reported, with fetal outcomes reported in 459/843 (54.4 %) of those infants. This enabled the calculation of proportions of pregnancy cases with the main pregnancy outcomes and of fetal cases with malformation. The number of reported pregnancies was significantly higher in PRIM than in the registry, showing that structured use of pharmacovigilance data enables speedier assessment of risks of maternal drug exposure.

Social Media Surveillance of Multiple Sclerosis Medications Used During Pregnancy and Breastfeeding: Content Analysis.

BACKGROUND: Multiple sclerosis (MS) is a chronic neurological disease occurring mostly in women of childbearing age. Pregnant women with MS are usually excluded from clinical trials; as users of the internet, however, they are actively engaged in threads and forums on social media. Social media provides the potential to explore real-world patient experiences and concerns about the use of medicinal products during pregnancy and breastfeeding. OBJECTIVE: This study aimed to analyze the content of posts concerning pregnancy and use of medicines in online forums; thus, the study aimed to gain a thorough understanding of patients' experiences with MS medication. METHODS: Using the names of medicinal products as search terms, we collected posts from 21 publicly available pregnancy forums, which were accessed between March 2015 and March 2018. After the identification of relevant posts, we analyzed the content of each post using a content analysis technique and categorized the main topics that users discussed most frequently. RESULTS: We identified 6 main topics in 70 social media posts. These topics were as follows: (1) expressing personal experiences with MS medication use during the reproductive period (55/70, 80%), (2) seeking and sharing advice about the use of medicines (52/70, 74%), (3) progression of MS during and after pregnancy (35/70, 50%), (4) discussing concerns about MS medications during the reproductive period (35/70, 50%), (5) querying the possibility of breastfeeding while taking MS medications (30/70, 42%), and (6) commenting on communications with physicians (26/70, 37%). CONCLUSIONS: Overall, many pregnant women or women considering pregnancy shared profound uncertainties and specific concerns about taking medicines during the reproductive period. There is a significant need to provide advice and guidance to MS patients concerning the use of medicines in pregnancy and postpartum as well as during breastfeeding. Advice must be tailored to the circumstances of each patient and, of course, to the individual medicine. Information must be provided by a trusted source with relevant expertise and made publicly available.

Risk of Cleft Lip and/or Palate Associated With Antiepileptic Drugs: Postmarketing Safety Signal Detection and Evaluation of Information Presented to Prescribers and Patients.

BACKGROUND: The aim was to analyze safety data associated with the maternal use of antiepileptic drugs in pregnancy and to assess the risk of cleft lip and/or palate (CL/P) as an outcome in the neonate. A parallel objective was to assess the completeness of the safety information concerning pregnancy exposures in the Summary of Product Characteristics (SmPCs) and the Patient Information (PI) in the USA and the UK. METHODS: We analyzed individual case safety reports of CL/P associated with antiepileptic drugs in the FDA Adverse Event Reporting System. For the antiepileptic drugs with signals (EB05 ≥ 2), we reviewed Drug Analysis Prints for CL/P cases in the UK Medicines and Healthcare products Regulatory Agency (MHRA). We performed descriptive analyses of relevant SmPCs and PIs in the UK and the USA using a checklist of recommendations collected from the literature. RESULTS: In total 817 CL/P reports were identified for 12 antiepileptic drugs in the FDA Adverse Event Reporting System. Ten of the 12 antiepileptic drugs were associated with 156 CL/P cases in the MHRA Sentinel. Safety information concerning pregnancy was found to be more comprehensive in UK SmPCs than in the US equivalents. CONCLUSIONS: There is statistical disproportionality in individual case safety reports indicative of an increased risk of CL/P with 12 antiepileptic drugs studied. More studies are required to explore the association between in utero exposure to antiepileptic drugs and the risk of CL/P. There are inconsistencies between the UK and US safety labels. CL/P associated with antiepileptic drugs is an important topic and requires providing inclusive, unbiased, up-to-date information to prescribers and women of childbearing age.
