INTRODUCTION: Evidence-based clinical data on coronavirus disease 2019 (COVID-19) pharmacotherapies are scarce.
OBJECTIVE: This study documented and characterized COVID-19 cases reported in individuals receiving treatment with Pfizer pharmaceutical products and cases that reported use of Pfizer pharmaceutical products for COVID-19 treatment.
METHODS: This retrospective observational review leveraged the Pfizer safety database containing adverse event data collected in association with use of Pfizer products between 1 October, 2019, and 25 June, 2020; the database includes worldwide adverse event data from various sources. Selected Medical Dictionary for Drug Regulatory Activities (MedDRA®) Preferred Terms and subsequent clinical review were used to characterize COVID-19 cases.
RESULTS: Over 1500 relevant cases were identified over an 8-month period. In cases that reported COVID-19, immunosuppressant/immunomodulating agents, followed by anticoagulant/antithrombic agents and corticosteroids, were the most frequently reported agents. The frequent reporting of immunosuppressant/immunomodulating agents among cases of COVID-19 suggests increased vulnerability to infection among treated patients, either because of immunosuppressive effects of certain agents or the nature of the underlying treated condition. In cases involving off-label pharmacotherapy use for the treatment of COVID-19-related conditions, the most frequently reported therapeutic classes included antibiotics, antimalarial agents, antivirals/antiretroviral agents, immunosuppressant/immunomodulating agents, corticosteroids, anticoagulants, and immunoglobulin/interferons. The most frequently reported pharmacotherapeutic agents were azithromycin and chloroquine/hydroxychloroquine, followed by lopinavir-ritonavir, ceftriaxone, and tofacitinib. The most frequently reported clinical adverse events associated with azithromycin (as sole therapy or combined with chloroquine/hydroxychloroquine) include electrocardiogram QT prolonged, drug interaction, hepatitis, diarrhea, and hepatitis acute. Regarding cardiac-related events, 19% (120/645) of azithromycin cases reported events associated with QT prolongation/torsade de pointes (which included seven fatal cardiac events). The most frequently reported clinical adverse events associated with other commonly used agents are also presented.
CONCLUSIONS: This pharmacovigilance surveillance study provides a unique characterization of cases in which a broad range of pharmaceutical products was reported in relation to COVID-19.
