An FDA conducted case control study in Medicare compared new users of PPIs versus new users of histamine-2 receptor antagonists and found that PPIs were not associated with increased risk uncomplicated or complicated (ICU, mechanical ventilation, death) COVID-19 hospitalizations. This provided reassurance to FDA that regulatory action was not needed. This resulted in a publication. Pharmacotherapy publication, 2024 . Angiotensin-converting enzyme (ACE) Inhibitors (multiple) and angiotensin receptor blockers (ARB) (multiple) Multiple NDAs Multiple sponsors Medicare claims data Case-control study In FDA’s review of ACE inhibitors or ARBs, an FDA conducted case-control study in Medicare evaluated the effect of ACE inhibitors or ARBs on the risk of developing severe COVID-19 and found that use of these drugs was not associated with increased risk of hospitalized COVID-19 or COVID-19-related mortality. No labeling changes were warranted. This resulted in a publication. Journal of General Internal Medicine publication, 2021. EPOGEN, PROCRIT, ARANESP (Erythropoietin stimulating agents (ESA)) BLA 103234 and 103951 Amgen Medicare Retrospective cohort study FDA reviewed the effect of the REMS for ESA use for chemotherapy-induced anemia, during and after the discontinuation of the REMS, and conducted a restrospective cohort study in Medicare that showed that the REMS had minimal impact on ESA use or transfusion rates and that the removal of the REMS did not affect subsequent ESA use or blood transfusions. Study results provided reassurance that FDA's removal of the REMS had not led to increased ESA use or transfusions. This resulted in a publication. Pharmacoepidemiology Drug Safety publication, 2021 . LYBREL (ethinyl estradiol; levonorgestrel) NDA 021864 Pfizer Sentinel System Retrospective cohort study An FDA conducted retrospective cohort study evaluated the risk of venous thromboembolism (VTE) for extended cycle contraceptives to determine whether these posed a greater risk of VTE due to increased hormone exposure, compared to 28-day products. The study provided reassurance that VTE risk was not substantially different between traditional and extended use oral contraceptives. JAMA Publication 2018 Januvia (sitagliptin) NDA 021995 Merck Pregnancy registry Prospective registry study A prospective study conducted by the Sponsor in a pregnancy registry identified too few exposed pregnancy outcomes to support definitive conclusions about overall malformation risk or for making comparisons of the frequencies of specific birth defects. Section 8 of the labeling was updated to reflect that the data available for pregnant women exposed to sitagliptin were not sufficient to inform a drug- associated risk for major birth defects and miscarriage.
