Background: Second-generation antipsychotics (SGAs), also called atypical antipsychotics, are common therapies for women with a spectrum of psychiatric disorders. No systematically ascertained human reproductive safety data are available for lurasidone, and prospective data for quetiapine are limited, making decisions regarding use of these medications during pregnancy complicated. Materials and Methods: The National Pregnancy Registry for Psychiatric Medications is a prospective cohort study designed to collect reproductive safety data relative to SGAs. Pregnant women aged 18-45 years, with psychiatric illness and prenatal psychotropic medication exposure completed three phone interviews during pregnancy and the postpartum period. Cases of presumed malformations are abstracted from medical records for adjudication by a teratologist blinded to medication exposure. Results: Of 2,293 women enrolled at the time of analysis, 134 in the lurasidone group, 264 in the quetiapine group, and 886 controls completed the postpartum interview and were therefore eligible for inclusion. Dropped or lost-to-follow-up participants (13%) and those currently pregnant were excluded. Participants were predominantly White, college-educated, and married (lurasidone = 88.1%, 76.9%, 77.6%; quetiapine = 89.8%, 71.2%, 75.0%; controls = 92.7%, 86.7%, 89.1%). Absolute risks of major malformations were 2.19% (lurasidone), 1.85% (quetiapine), and 1.77% (controls). Odds ratios comparing lurasidone and quetiapine with controls were 1.24 (95% confidence interval [CI] = 0.36-4.32) and 1.04 (95% CI = 0.38-2.85), respectively. Conclusions: No specific patterns of malformations were observed in infants exposed to the medications of interest. Lurasidone and quetiapine did not appear to be major teratogens, but further information is needed to refine risk estimates. Food and Drug Administration guidance underscores the importance of pregnancy registries. Clinical trial number: NCT01246765.

Purpose/background: Since its US Food and Drug Administration approval in 1996, olanzapine has been one of the most commonly prescribed atypical antipsychotics, making a better understanding of its reproductive safety profile critical. The goal of the current analysis was to determine the risk of major malformations among infants exposed to olanzapine during pregnancy compared with a group of nonexposed infants., Methods/procedures: The National Pregnancy Registry for Psychiatric Medications is a prospective pharmacovigilance program in which pregnant women are enrolled and interviewed during pregnancy and the postpartum period. Labor and delivery and pediatric medical records were screened for evidence of major malformations followed by adjudication by a dysmorphologist blinded to medication exposure. Infants with first-trimester exposure to olanzapine were compared with controls without second-generation antipsychotic exposure., Findings/results: As of April 18, 2022, 2619 women have enrolled in the study. At the time of data extraction, 49 olanzapine-exposed infants and 1156 infants in the comparison group were eligible for these analyses. There were no major malformations associated with olanzapine exposure in the first trimester. The absolute risk for major malformations in the exposure group was 0.00% (95% confidence interval, 0.00-7.25) for olanzapine compared with 1.64% (95% confidence interval, 0.99-2.55) in the control group., Implications/conclusions: In this prospective cohort, no major malformations were associated with olanzapine exposure during the first trimester. Although these data are preliminary and cannot rule out more modest effects, they are nonetheless important, adding to the growing reproductive safety data for olanzapine., (Copyright © 2023 Wolters Kluwer Health, Inc.

Importance: Although antipsychotic drugs cross the placenta and animal data suggest potential neurotoxic effects, information regarding human neurodevelopmental teratogenicity is limited., Objective: To evaluate whether children prenatally exposed to antipsychotic medication are at an increased risk of neurodevelopmental disorders (NDD)., Design, Settings, and Participants: This birth cohort study used data from the Medicaid Analytic eXtract (MAX, 2000-2014) and the IBM Health MarketScan Research Database (MarketScan, 2003-2015) for a nationwide sample of publicly (MAX) and privately (MarketScan) insured mother-child dyads with up to 14 years of follow-up. The MAX cohort consisted of 2 034 883 children who were not prenatally exposed and 9551 who were prenatally exposed to antipsychotic medications; the MarketScan consisted of 1 306 408 and 1221 children, respectively. Hazard ratios were estimated through Cox proportional hazards regression, using propensity score overlap weights for confounding control. Estimates from both cohorts were combined through meta-analysis., Exposures: At least 1 dispensing of a medication during the second half of pregnancy (period of synaptogenesis), assessed for any antipsychotic drug, at the class level (atypical and typical), and for the most commonly used drugs (aripiprazole, olanzapine, quetiapine, risperidone, and haloperidol)., Main Outcomes and Measures: Autism spectrum disorder, attention-deficit/hyperactivity disorder, learning disability, speech or language disorder, developmental coordination disorder, intellectual disability, and behavioral disorder, identified using validated algorithms, and the composite outcome of any NDD. Data were analyzed from April 2020 to January 2022., Results: The MAX cohort consisted of 2 034 883 unexposed pregnancies and 9551 pregnancies with 1 or more antipsychotic drug dispensings among women with a mean (SD) age of 26.8 (6.1) years, 204 (2.1%) of whom identified as Asian/Pacific Islander, 2720 (28.5%) as Black, 500 (5.2%) as Hispanic/Latino, and 5356 (56.1%) as White. The MarketScan cohort consisted of 1 306 408 unexposed and 1221 exposed pregnancies among women with a mean (SD) age of 33.1 (5.0) years; race and ethnicity data were not available. Although the unadjusted results were consistent with an approximate 2-fold increased risk for most exposure-outcome contrasts, risks were no longer meaningfully increased after adjustment (eg, pooled unadjusted vs adjusted hazard ratios [95% CI] for any NDD after any antipsychotic exposure: 1.91 [1.79-2.03] vs 1.08 [1.01-1.17]), with the possible exception of aripiprazole (1.36 [1.14-1.63]). Results were consistent across sensitivity analyses., Conclusions and Relevance: The findings of this birth cohort study suggest that the increased risk of NDD seen in children born to women who took antipsychotic drugs late in pregnancy seems to be explained by maternal characteristics and is not causally related with prenatal antipsychotic exposure. This finding highlights the importance of closely monitoring the neurodevelopment of the offspring of women with mental illness to ensure early intervention and support. The potential signal for aripiprazole requires replication in other data before causality can be assumed.

Objective: Second-generation antipsychotics (SGAs) are prescribed for a wide range of indications in women of reproductive age. The National Pregnancy Registry for Atypical Antipsychotics (NPRAA) was established to determine the risk of major malformations among infants exposed to these medications during the first trimester relative to a comparison group of unexposed infants of mothers with histories of psychiatric morbidity., Methods: Women, aged 18-45 years, with histories of psychiatric illness were prospectively followed through pregnancy and during the postpartum period. Pediatric and maternal medical records were obtained and screened for evidence of major malformations. Potential cases were adjudicated by a dysmorphologist who was blinded to drug exposure.. Recruitment to the Registry, which is based at the Ammon-Pinizzotto Center for Women's Mental Health at Massachusetts General Hospital (MGH), includes nationwide provider referral, self-referral, and advertisement through the MGH Center for Women's Mental Health website., Results: As of April 9, 2020, 1,906 women had enrolled, including 889 in the exposure group and 1,017 controls. A total of 1,311 women completed the study and were eligible for inclusion in the analysis. Medical records were obtained for 81.3% of participants. Among 640 live births in the exposure group, 16 (2.50%) had confirmed major malformations reported, and among 704 live births in the control group, 14 (1.99%) had confirmed major malformations reported. The estimated odds ratio for major malformations comparing exposed and unexposed infants was 1.48 (95% CI, 0.625-3.517)., Conclusions: Data from the Registry assessing SGAs as a class indicate that they are unlikely to have a major teratogenic effect. These findings provide pertinent information for women and their health care providers regarding decisions about atypical antipsychotic use during pregnancy., Trial Registration: ClinicalTrails.gov identifier: NCT01246765., (© Copyright 2021 Physicians Postgraduate Press, Inc.)

Aripiprazole has become one of the most commonly prescribed psychotropics, making a more comprehensive understanding of its reproductive safety profile a priority. The goal of the current analysis was to determine the risk of major malformations in infants exposed during the first trimester of pregnancy to aripiprazole compared to infants whose mothers had psychiatric diagnoses but did not use an atypical antipsychotic during pregnancy. The National Pregnancy Registry for Atypical Antipsychotics is a prospective pharmacovigilance program in which pregnant women are enrolled and interviewed during pregnancy and the postpartum period. Medical records are assessed to confirm presence or absence of major malformations. Pregnant women ages 18-45 with psychiatric diagnoses are enrolled. As of April 2020, N = 848 women who had delivered infants were eligible for analyses. A total of 158 women with first trimester exposure to aripiprazole were compared to 690 controls. For 163 infants born to women in the exposed group, seven major malformations were confirmed (4.29%), compared to fourteen of the 690 unexposed infants (1.99%). The unadjusted odds ratio for major malformations between aripiprazole-exposed and unexposed infants was 2.21 (95% confidence interval [CI] = (0.88, 5.57) The adjusted odds ratio for major malformations was 1.35 (95% confidence interval [CI] = (0.43, 4.20). After adjustment for confounding variables, the risk of major malformations after first trimester exposure to aripiprazole was not significant compared to controls. While these results are reassuring, they are limited by relatively small numbers of participants. Future analyses with larger numbers are expected to provide more of a complete and precise reproductive safety profile regarding aripiprazole use during pregnancy. Trial registration: clinicaltrials.gov NCT01246765.

Objective: Second-generation antipsychotics are commonly prescribed to reproductive-age women for the treatment of a spectrum of psychiatric disorders. Quetiapine is the most commonly prescribed medication in this class, and therefore a better understanding of its reproductive safety profile is critical. The goal of this study was to determine the risk of major malformations among infants exposed to quetiapine during pregnancy compared with a group of infants whose mothers had a history of psychiatric morbidity but who did not use a second-generation antipsychotic during pregnancy., Method: The National Pregnancy Registry for Atypical Antipsychotics interviews pregnant women ages 18-45 during pregnancy and the postpartum period. Obstetric, labor, and delivery medical records and pediatric medical records from the first 6 months of life were screened for evidence of major malformations, followed by adjudication by a blinded dysmorphologist. Women with first-trimester exposure to quetiapine were compared with control subjects without exposure to second-generation antipsychotics., Results: As of March 2017, 888 women had enrolled prospectively and 357 were eligible for analysis. Of these, 152 women with first-trimester exposure to quetiapine were compared with 205 control subjects without any second-generation antipsychotic exposure. For the 155 infants born to women in the exposed group (including three sets of twins), two major malformations were confirmed (1.3%), compared with three major malformations among the 210 infants born in the unexposed group (including five sets of twins) (1.4%). The unadjusted odds ratio for major malformations between infants with and without quetiapine exposure was 0.90 (95% CI=0.15, 5.46), which is consistent with the pooled estimate of the available controlled data on fetal exposure to quetiapine., Conclusions: These data regarding the safety of fetal exposure to quetiapine in a small sample of well-characterized participants are reassuring given that the confidence interval does not exceed a fivefold increased risk of major malformations relative to psychiatric control subjects. Future analyses based on ongoing data collection will produce more precise estimates.

Importance: The frequency of antipsychotic (AP) use during pregnancy has approximately doubled during the last decade. However, little is known about their safety for the developing fetus, and concerns have been raised about a potential association with congenital malformations., Objective: To examine the risk for congenital malformations overall and cardiac malformations associated with first-trimester exposure to APs., Design, Setting, and Participants: This nationwide sample of 1 360 101 pregnant women enrolled in Medicaid with a live-born infant constituted the pregnancy cohort nested in the Medicaid Analytic Extract database, which included data from January 1, 2000, to December 31, 2010. Participants were enrolled in Medicaid from 3 months before their last menstrual period through at least 1 month after delivery. Relative risks (RRs) were estimated using generalized linear models with fine stratification on the propensity score to control for the underlying psychiatric disorders and other potential confounders. Data were analyzed during 2015., Exposures: Use of APs during the first trimester, the etiologically relevant period for organogenesis., Main Outcomes and Measures: Major congenital malformations overall and cardiac malformations identified during the first 90 days after delivery., Results: Of the 1 341 715 pregnancies that met inclusion criteria (mean [SD] age of women, 24.02 [5.77] years), 9258 (0.69%) filled at least 1 prescription for an atypical AP and 733 (0.05%) filled at least 1 prescription for a typical AP during the first trimester. Overall, 32.7 (95% CI, 32.4-33.0) per 1000 births not exposed to APs were diagnosed with congenital malformations compared with 44.5 (95% CI, 40.5-48.9) per 1000 births exposed to atypical and 38.2 (95% CI, 26.6-54.7) per 1000 births exposed to typical APs. Unadjusted analyses suggested an increased risk for malformations overall for atypical APs (RR, 1.36; 95% CI, 1.24-1.50) but not for typical APs (RR, 1.17; 95% CI, 0.81-1.68). After confounding adjustment, the RR was reduced to 1.05 (95% CI, 0.96-1.16) for atypical APs and 0.90 (95% CI, 0.62-1.31) for typical APs. The findings for cardiac malformations were similar. For the individual agents examined, a small increased risk in overall malformations (RR, 1.26; 95% CI, 1.02-1.56) and cardiac malformations (RR, 1.26; 95% CI, 0.88-1.81) was found for risperidone that was independent of measured confounders., Conclusions and Relevance: Evidence from this large study suggests that use of APs early in pregnancy generally does not meaningfully increase the risk for congenital malformations overall or cardiac malformations in particular. The small increase in the risk for malformations observed with risperidone requires additional study.

Objective: Second-generation antipsychotics are used to treat a spectrum of psychiatric illnesses in reproductive-age women. The National Pregnancy Registry for Atypical Antipsychotics was established to determine the risk of major malformations among infants exposed to second-generation antipsychotics during pregnancy relative to a comparison group of unexposed infants of mothers with histories of psychiatric morbidity., Method: Women were prospectively followed during pregnancy and the postpartum period; obstetric, labor, delivery, and pediatric medical records were obtained. Eligible enrollees were pregnant women ages 18-45. The Registry is based at the Center for Women's Mental Health at Massachusetts General Hospital. Women were recruited through provider referral, self-referral, and the Center's web site., Results: As of December 2014, 487 women were enrolled: 353 who used second-generation antipsychotics and 134 comparison women. Medical records were obtained for 82% of participants. A total of 303 women had completed the study and were eligible for inclusion in the analysis. Of 214 live births with first-trimester exposure to second-generation antipsychotics, three major malformations were confirmed. In the control group (N=89), one major malformation was confirmed. The absolute risk of major malformations was 1.4% for exposed infants and 1.1% for unexposed infants. The odds ratio for major malformations comparing exposed infants with unexposed infants was 1.25 (95% CI=0.13-12.19)., Conclusions: The results suggest that it would be unlikely for second-generation antipsychotics to raise the risk of major malformations more than 10-fold beyond that observed in the general population or among control groups using other psychotropic medications. If the estimate stabilizes around the null with ongoing data collection, findings may be reassuring for both clinicians and women trying to make risk-benefit treatment decisions about using atypical antipsychotics during pregnancy. These findings are timely given the renewed focus of regulatory agencies on reproductive safety.

Objective: Atypical antipsychotics are widely used by reproductive-age women to treat a spectrum of psychiatric illnesses. Despite widespread use of this class of agents in women of childbearing potential, reproductive safety data across these medicines remain limited. The National Pregnancy Registry for Atypical Antipsychotics (NPRAA) at Massachusetts General Hospital was established in 2008 to address this knowledge gap., Method: Data are prospectively collected from pregnant women, ages 18-45 years, using 3 phone interviews conducted at the following times: (1) proximate to the time of enrollment, (2) 7 months' gestation, and (3) 2-3 months postpartum. Subjects include pregnant women with histories of fetal exposure to second-generation antipsychotics and a comparison group of nonexposed pregnant women. Medical record release authorization is obtained for obstetric, labor and delivery, and newborn pediatric (up to 6 months of age) records. Information regarding the presence of major malformations is abstracted from the medical records along with other data regarding neonatal and maternal health outcomes. Identified cases of congenital malformations are sent to a dysmorphologist blinded to drug exposure for final adjudication., Results: As of May 2014, 428 subjects have enrolled in the NPRAA. Efforts continue to increase enrollment for the purpose of enhancing the capacity to define risk estimates of in utero exposure to atypical antipsychotics., Conclusions: The NPRAA gathers prospective data regarding risk for critical outcomes following use of atypical antipsychotics during pregnancy. The NPRAA offers a systematic way to collect reproductive safety information that informs the care of women who use these agents to sustain psychiatric well-being., Trial Registration: ClinicalTrials.gov identifier: NCT01246765., (© Copyright 2015 Physicians Postgraduate Press, Inc.)
