The Claims Library as a Component of Product Liability and False Claims Act Defenses

The Claims Library as a Component of Product Liability and False Claims Act Defenses

Life sciences companies are facing increased exposure to product liability litigation and government enforcement. This trend is being fueled by expanding mass-tort activity, whistleblower actions, greater scrutiny of direct-to-consumer and digital promotion, and the ability of plaintiffs and regulators to examine years of promotional communications across multiple channels.

In this environment, companies may need to demonstrate more than the fact that an individual asset passed through Medical, Legal, and Regulatory review. They may also need to show the evidence supporting a claim, the context in which it was approved, the applicable qualifications and safety information, and the controls used to prevent unsupported or misleading communications.

A well-developed Claims Library can help provide that record.

Beyond MLR Efficiency

Claims Libraries have traditionally been used to help MLR teams, commercial personnel, and agencies verify that promotional claims are accurate, substantiated, and consistent with FDA-approved labeling.

They also improve efficiency by creating a controlled source of approved claims linked to supporting references, labeling, qualifications, safety information, and permitted usage.

These same capabilities may also support a company's legal defense.

Product Liability Support

Product liability allegations may include claims that a manufacturer overstated a product's benefits, failed to communicate a material risk, or disseminated false or misleading information.

A Claims Library can help counsel determine:

  • What evidence supported a claim;
  • How the claim related to the approved labeling;
  • What qualifications or safety information were required;
  • Where and how the claim was approved for use; and
  • When the claim was revised, restricted, or retired.

This documentation does not prevent litigation or create an automatic defense. It can, however, help demonstrate that the company maintained a structured process designed to support accurate and appropriately balanced communications.

False Claims Act Support

Claims Libraries may also be relevant in False Claims Act matters involving allegations that improper promotional communications contributed to prescriptions or reimbursement by government healthcare programs.

A well-governed library can help establish what claims were approved, the evidence available at the time, the controls used to prevent unsupported messaging, and the distinction between approved promotion and legitimate scientific exchange.

This may be particularly important when companies must respond to allegations based on communications created years earlier.

An Enterprise Risk-Control Resource

The Claims Library should therefore be viewed as more than an MLR efficiency tool. When properly maintained, it can serve as an enterprise record connecting claims to their evidence, approved context, safety requirements, usage limitations, and review history.

Its value depends on strong governance, including version control, documented approvals, clear ownership, current source materials, and consistent use across the organization.

A Claims Library cannot eliminate product liability or False Claims Act risk. It can, however, provide valuable contemporaneous evidence that the company used a disciplined process to substantiate claims, communicate risk appropriately, and prevent unsupported promotional messaging.
