MLR REVIEW PROCESS

The MLR review process, explained

For most pharma and biotech companies, Medical, Legal & Regulatory review is the biggest bottleneck between creating content and getting it to market. This guide explains how the process works, why it takes so long, and how AI-powered platforms like ERMA cut review times by more than 60%.

Who is involved in MLR review?

Whether you're reviewing a sales aid, website, email campaign, congress booth, patient brochure, or social post, every promotional piece passes through multiple reviewers before publication — each evaluating content from a different perspective.

COMMON REVIEWERS

REVIEWER PRIMARY RESPONSIBILITY
Medical Scientific accuracy and evidence
Regulatory FDA compliance and labeling consistency
Legal Risk management and promotional compliance
Marketing Brand strategy and messaging
Medical Writer Content quality and supporting references

Why MLR reviews take so long

Every organization has its own workflow, but several bottlenecks are nearly universal.

01

Manual claim identification

Reviewers read documents line by line looking for promotional claims — time-consuming and inconsistent between reviewers.

02

Reference matching

Every efficacy, safety, or clinical claim must be tied to approved evidence — searching PDFs, study versions, and citations by hand.

03

Multiple review cycles

Draft → Medical → Marketing → Regulatory → Legal → Approval. A single change can trigger another full cycle.

04

Email-based collaboration

Email chains make it hard to know which version is current, who approved, and what comments are outstanding.

05

Static claims databases

Traditional systems only recognize claims someone already entered — new wording or evolving language is easily missed.

The traditional MLR workflow

Workflows vary, but a typical promotional review moves through eight stages.

  1. 01

    Content creation

    Marketing or Medical creates the promotional content.

  2. 02

    Supporting references

    Publications, prescribing information, and internal references are attached.

  3. 03

    MLR submission

    Content enters the review system and reviewers are assigned.

  4. 04

    Medical review

    Reviewers verify scientific accuracy, clinical context, and appropriate references.

  5. 05

    Regulatory review

    Regulatory confirms alignment with approved indication, FDA guidance, labeling, and fair balance.

  6. 06

    Legal review

    Legal evaluates promotional risk and compliance.

  7. 07

    Revision cycles

    Comments are consolidated and revisions are made.

  8. 08

    Final approval

    Approved materials are archived with complete audit history.
