Pharmacovigilance Best Practices for Clinical and Early Post-Approval Biopharma

The idea of selecting, implementing, and deploying pharmacovigilance software is overwhelming for smaller companies. Smaller clinical and early post-approval stage biopharma companies have to make do with significantly fewer resources and they are understandably quick to look for outside help.

Analysis of Post-Marketing Safety Signals for COVID-19 Therapies

We reviewed the top 6 most widely used COVID-19 treatments using Q2 2020 FAERS data. The report includes new potential safety signals, dechallenge and rechallenge data, detailed signal analysis and ROR forest plots, and top 10 highest reported adverse event tables for each product.

A Pharmacovigilance Signaling System Based on FDA Regulatory Action and Post-Marketing Adverse Event Reports

Many serious drug adverse events (AEs) only manifest well after regulatory approval. Therefore, the development of signaling methods to use with post-approval AE databases appears vital to comprehensively assess real-world drug safety. However, with millions of potential drug–AE pairs to analyze, the issue of focus is daunting.

The Weber Effect and FAERS: Analysis of Sixty-Two Drugs Approved from 2006 to 2010

Most of the modern adverse event reporting into FAERS does not follow the pattern described by the ‘Weber Effect’. Modern FAERS reporting has improved greatly over the last decade and will be an increasingly important factor in determining the overall safety profile of FDA approved prescription drugs

Stimulated Reporting: The Impact of US Food and Drug Administration-Issued Alerts on the Adverse Event Reporting System (FAERS)

“Stimulated reporting” is the concept that public disclosure of a safety issue by the issuance of an FDA alert or warning, or the clustering of adverse event reports triggered by consumer-based support group and/or litigation, will result in substantially increased reporting rates for the affected drug. This publication refutes this widely held assumption.

Neuropsychiatric adverse effects of oseltamivir in the FDA Adverse Event Report System, 1999-2012

Publications from Roche and a case-control study suggest that there is no evidence, or plausible mechanism of action, to link neuropsychiatric adverse events to Tamiflu (oseltamivir). Cochrane Collaborators, the BMJ, and others, however, contend that many of Roche’s data remain unavailable.

A Survey of the FDA's AERS Database Regarding Muscle and Tendon Adverse Events Linked to the Statin Drug Class

Cholesterol management drugs known as statins are widely used and usually well tolerated. However, a variety of muscle-related side effects can arise. We conducted a review of post-approval muscle and tendon AE reports in association with statin use, to assess differences within the drug class.

Analysis of Spontaneous Postmarket Case Reports Submitted to the FDA Regarding Thromboembolic Adverse Events and JAK Inhibitors

A systematic review of FAERS found elevated reporting for both tofacitinib and ruxolitinib for certain thromboembolic adverse events.
