What Is an MDL? Understanding the GLP-1 Multidistrict Litigation

Introduction: Decoding the Legal Process

If you are researching lawsuits against the makers of Ozempic, Wegovy, Mounjaro, or Zepbound, you have almost certainly encountered the term MDL 3094 or Multidistrict Litigation. You may have also heard people refer to these cases as a "class action lawsuit."

Here's the critical distinction: While many people casually use the term "class action" to describe these cases, the GLP-1 litigation is actually an MDL—and this is not just legal semantics.

Understanding the difference between a class action and an MDL fundamentally changes:

• How you file your claim
• How much compensation you could receive
• How your individual story is told in court
• Your level of control over your case
• The timeline for resolution

This article will explain in plain English what an MDL is, how it works, where the GLP-1 litigation currently stands, and, most importantly, what you need to do to protect your rights.

The Fundamental Difference: MDL vs. Class Action

The simplest way to understand the difference is to look at how plaintiffs (the injured people) are treated and how compensation is determined.

Side-by-Side Comparison

Why These Differences Matter to You

In a Class Action:

• You might receive a small, predetermined amount
• Your unique injuries and suffering may not be fully valued
• You have little say in strategy or settlement terms
• The focus is on efficiency over individual justice

In an MDL:

• Your compensation reflects YOUR actual damages
• A person with permanent gastroparesis requiring a feeding tube will receive more than someone with temporary symptoms
• Your attorney represents YOUR interests specifically
• Your medical evidence, lost wages, and pain and suffering are individually evaluated

Why Is the GLP-1 Case an MDL? (Not a Class Action)

The Legal Decision

In February 2024, the Judicial Panel on Multidistrict Litigation (JPML)—a special panel of federal judges—officially centralized the GLP-1 cases into:

• MDL No. 3094
• Case Name: In re: Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RAs) Products Liability Litigation
• Presiding Judge: The Honorable Karen S. Marston
• Location: United States District Court, Eastern District of Pennsylvania (Philadelphia)

Why the Court Chose an MDL Structure

The JPML determined that an MDL was appropriate because:

1. Similar Legal Questions, But Unique Injuries

Common Legal Issues (suitable for coordinated handling):

• Did Novo Nordisk and Eli Lilly know about gastroparesis and NAION risks?
• Were the drug labels adequate warnings?
• What did internal company documents reveal?
• What did clinical trials show?
• When should warnings have been updated?

Highly Individual Factors (requiring separate evaluation):

• The severity of each person's side effect (e.g., gastroparesis)
• Whether symptoms are temporary or permanent
• Specific medical expenses and treatments needed
• Impact on work, income, and quality of life
• Pre-existing conditions and other health factors
• Length of drug use and dosage

The Court's Reasoning: Medical injuries are too unique and individualized for a class action. One person might have suffered two weeks of nausea and vomiting that resolved after stopping the medication, while another might have permanent stomach paralysis requiring a feeding tube for life. These cases cannot be treated identically.

2. Efficiency Without Sacrificing Individual Justice

An MDL allows the court to:

• Consolidate pretrial proceedings (discovery, depositions, expert reports)
• Avoid duplicative litigation (drug companies don't answer the same questions 5,000 times)
• Conserve judicial resources (one judge manages common issues)
• Maintain individual case value (your specific damages are preserved)

3. Magnitude and Complexity

By early 2024, the JPML recognized:

• Hundreds of cases had already been filed across multiple federal districts
• Thousands more were anticipated
• Complex scientific and medical questions required coordinated expert testimony
• Extensive discovery from pharmaceutical companies would be needed
• Without coordination, decades of duplicative litigation would ensue

How the MDL Process Works: Your Case Journey

If you decide to move forward with a claim, your case will likely follow this structured path within the MDL system. Understanding these phases helps you know what to expect.

Phase 1: Case Filing and MDL Transfer

What Happens:

Step 1: You Hire an Attorney

• You consult with a lawyer experienced in pharmaceutical litigation
• Your attorney evaluates your case for merit
• You sign a contingency fee agreement

Step 2: Your Complaint is Filed

• Your attorney files a formal lawsuit in federal court
• The complaint names you as plaintiff and the drug manufacturers as defendants
• It details your specific injuries, when you used the drug, and what damages you suffered

Step 3: Transfer to MDL Court

• Your case is transferred to the Eastern District of Pennsylvania
• Judge Marston assumes oversight of your case
• Your case receives an MDL case number

Your Role: Provide detailed information about your drug use, symptoms, and medical treatment

Timeline: 1–3 months

Phase 2: Centralized Discovery (The "Shared" Phase)

This is where the MDL structure provides tremendous efficiency and power.

What Happens:

Instead of Novo Nordisk and Eli Lilly answering the same questions in 3,000+ individual cases, they answer them once in coordinated discovery. Plaintiffs' attorneys work together through:

Plaintiffs' Steering Committee (PSC):

• A group of experienced lead attorneys appointed by Judge Marston
• They coordinate discovery strategy for all plaintiffs
• They have the resources to take on billion-dollar pharmaceutical companies
• Your individual attorney works with the PSC to advance your case

Major Discovery Activities:

Document Production:

• Internal company emails and memos
• Clinical trial data (published and unpublished)
• Adverse event reports submitted to the FDA
• Marketing materials and strategies
• Communications with the FDA
• Safety committee meeting minutes
• Expert consultant reports

Depositions:

• Corporate representatives (executives, scientists, marketing leads)
• FDA officials
• Clinical trial investigators
• Medical experts
• Key employees involved in drug development and safety monitoring

Expert Discovery:

Plaintiffs' experts provide reports on:

• Causation (how GLP-1 drugs cause gastroparesis and NAION)
• Standards of care for warnings
• Economic damages analysis

Defendants' experts respond with competing theories

The Power of Coordinated Discovery:

• Cost: Discovery costs are shared among all plaintiffs, not borne by you individually
• Expertise: Top pharmaceutical litigation experts dedicate full attention
• Smoking Guns: Centralized discovery is more likely to uncover damaging internal documents
• Pressure: Defendants face coordinated, well-funded opposition rather than piecemeal challenges

Your Role:

• Provide your medical records
• Complete interrogatories with your attorney (written questions)
• Potentially give a deposition about your specific case
• Stay in contact with your attorney

Timeline: 1–2 years (currently underway in MDL 3094)

Phase 3: Bellwether Trials (The "Test" Phase)

This is a unique and critical feature of MDLs.

What Are Bellwether Trials?

"Bellwether" is a shepherd's term for the lead sheep—the one with a bell that the flock follows. In an MDL, bellwether cases are a small group of representative cases (usually 6–12) selected to go to trial before the thousands of other cases are resolved.

Purpose of Bellwethers:

1. Test the Evidence: How do juries react to the scientific evidence, internal documents, and plaintiff testimony?
2. Establish Value: Jury verdicts provide a "market price" for different injury severities.
3. Encourage Settlement: After a few defense losses or large verdicts, companies typically enter serious settlement negotiations.
4. Reveal Strengths and Weaknesses: Both sides learn what arguments work and what doesn't.

Timeline: Bellwether trials typically begin 2–3 years after MDL formation

Phase 4: Settlement Negotiations (The "Global Resolution" Phase)

After bellwether trials establish value ranges, serious settlement negotiations typically begin.

How MDL Settlements Work:

Settlement Matrix Development: A structured system for valuing cases based on:

Injury Severity Tiers (example structure):

• Tier 1 (Transient symptoms):

• Nausea/vomiting resolved after stopping drug

• No hospitalization
• No permanent effects

• Tier 2 (Moderate gastroparesis):

• Gastroparesis diagnosis

• Some hospitalization or ER visits
• Symptoms improved but not fully resolved
• Able to eat with modifications

• Tier 3 (Severe gastroparesis):

• Confirmed gastroparesis requiring ongoing treatment

• Multiple hospitalizations
• Cannot maintain normal diet
• Significant life impact

• Tier 4 (Permanent disability):

• Permanent feeding tube dependency

• Gastric stimulator implant
• Cannot work
• Total life disruption

Additional Multipliers:

• Age
• Lost income documentation
• Pre-existing conditions
• Quality of medical documentation (strong evidence = higher value)

Your Settlement Decision:

Timeline: Settlements typically begin 3–5 years after MDL formation

Phase 5: Individual Resolution (The "Your" Phase)

If You Accept Settlement:

• Your attorney submits your case for valuation
• Settlement administrator reviews medical records
• You receive a settlement offer based on the matrix
• If accepted, payment typically arrives within 60–180 days
• Your attorney deducts contingency fee and expenses

If You Reject Settlement or No Settlement is Reached:

• Your case is "remanded" back to the federal court where it was originally filed
• You can proceed to individual trial
• Your attorney represents you through trial
• This is rare but preserves your right to seek full compensation

Common Misconceptions About MDLs

Myth 1: "I'll automatically get money from the lawsuit" Reality: You must file your own case through an attorney. There is no "automatic" inclusion or payment.

Myth 2: "Everyone gets the same settlement amount" Reality: Compensation is individualized based on YOUR specific injuries, medical expenses, and life impact.

Myth 3: "Class actions are better because they're faster" Reality: MDLs often resolve in similar timeframes, but provide much better compensation for serious injuries.

Myth 4: "I can just wait and see what happens" Reality: Statutes of limitations apply. Waiting too long means you lose your rights forever.

Myth 5: "My case is too small to matter" Reality: MDLs accommodate cases of all severity levels. Even "moderate" injuries can result in substantial compensation.

Myth 6: "I need to pay a lawyer upfront" Reality: Pharmaceutical product liability cases are handled on contingency—no fee unless you win.

Frequently Asked Questions

Q1: If I join the MDL, do I have to go to Pennsylvania for court? A: No. Almost all communication happens through your attorney. You typically won't need to travel to Philadelphia unless:

• Your case is selected as a bellwether (very rare)
• A deposition is required (can often be done locally)
• Trial is necessary (only if you reject settlement)

For most plaintiffs, participation is entirely through your local attorney with no travel required.

Q2: Can I still file if I signed a waiver or consent form before taking the drug? A: Yes, very likely. Consent forms don't waive your rights if:

• The form didn't adequately warn about gastroparesis or NAION
• The manufacturer failed to provide complete information to your doctor
• The risks weren't properly disclosed

Signing a general consent form almost never prevents a product liability lawsuit.

Q3: What if I used the drug for off-label weight loss (not FDA approved indication)? A: You can still file. Off-label use doesn't eliminate manufacturer responsibility to warn about risks. In fact:

• Millions used Ozempic off-label for weight loss before Wegovy approval
• Manufacturers benefited from off-label sales
• Failure to warn applies regardless of indication

Q4: Do I need to have stopped taking the drug to file a lawsuit? A: No, but:

• Most cases involve people who stopped due to severe side effects
• If you're still using the drug without problems, you may not have damages yet
• If you're still using despite symptoms, work with your doctor first

Never stop medication without doctor guidance, especially if you're diabetic.

Q5: My symptoms improved after stopping the drug. Can I still file? A: Possibly, depending on:

• How long symptoms lasted
• How severe they were
• What medical intervention was required
• Whether you have lasting effects

Even temporary but severe gastroparesis requiring hospitalization may warrant compensation. Consult an attorney for case-specific evaluation.

Q6: What if I have both gastroparesis AND vision loss (NAION)? A: You can participate in BOTH MDLs:

• MDL 3094 for gastroparesis/GI injuries
• MDL 3163 for NAION vision loss

Your attorney will file in both and coordinate. Total compensation would reflect both injuries.

Q7: How long do I have to file? (Statute of Limitations) A: This varies by state, but generally:

• 2–3 years from diagnosis or when you knew/should have known about the injury
• Some states have "discovery rule" extensions

Don't wait—evidence becomes harder to obtain over time. Critical: Missing the statute of limitations means you lose your rights FOREVER. Consult an attorney immediately if you're concerned about timing.

Q8: What if my doctor says my gastroparesis wasn't caused by the GLP-1 drug? A: Your doctor's opinion is just one factor. Your attorney will:

• Obtain medical records showing temporal relationship
• Hire expert witnesses to review your case
• Consider whether your doctor has bias or incomplete information
• Evaluate other evidence (timing, severity, other causes ruled out)

Don't self-reject your case based on one doctor's opinion.

Q9: Can I file if I live outside the United States? A: If you used the drug in the U.S. and developed injuries here, yes. If you're in another country:

• U.S. lawsuits may not be available
• Check if your country has separate litigation
• Consult with an attorney about jurisdiction

Q10: Do I have to testify or give a deposition? A: Possibly, but it's not as scary as it sounds:

• Depositions are usually conducted at your attorney's office or via video
• Your attorney prepares you thoroughly beforehand
• You simply answer questions truthfully about your experience
• Most plaintiffs in MDLs never give depositions (only a subset do)

If your case settles (most likely outcome), you probably won't testify.

Conclusion: Why Understanding MDLs Protects Your Rights

The distinction between an MDL and a class action is not academic—it's fundamental to protecting your legal rights and obtaining fair compensation.

Key Takeaways

Understanding MDLs Empowers You:

• You know you must take active steps to participate
• You understand your case is individual and valued specifically
• You have realistic expectations about timeline and process
• You can make informed decisions about settlement offers
• You recognize the importance of quality medical documentation

The Bottom Line:

• MDLs provide the efficiency of coordinated litigation
• While preserving the individual justice of personal representation
• Your severe injuries are valued appropriately
• You maintain control over your case outcome

Your Action Plan

If you believe you have a GLP-1 injury claim:

Do Not:

• Wait for a "settlement announcement" that will automatically include you
• Assume your case is "too small" to matter
• Delay because you're worried about costs (contingency fee = no upfront cost)
• Let the statute of limitations expire

The Stakes Are High

Gastroparesis, ileus, and NAION are life-altering injuries. Your compensation in an MDL could:

• Cover hundreds of thousands in medical expenses
• Replace lost income and earning capacity
• Provide for ongoing care and quality of life needs
• Hold pharmaceutical companies accountable for inadequate warnings

But only if you take action.
