Do You Qualify for a Dupixent Lawsuit?
Who qualifies for a Dupixent lawsuit?
You may qualify for a Dupixent lawsuit if you meet the following criteria:
Used Dupixent (dupilumab) for three months or longer.
Were diagnosed with cutaneous T-cell lymphoma (CTCL), mycosis fungoides, or Sézary syndrome after starting Dupixent.
Symptoms appeared 30 days or more after beginning Dupixent treatment.
You have not filed for bankruptcy or been convicted of a felony.
The diagnosis must be confirmed through skin biopsy and pathology report.
Medical records documenting Dupixent prescription, dosing, and duration of use are essential to establish your claim.
If you meet these criteria, you may be entitled to significant compensation for medical expenses, lost wages, pain and suffering, and other damages.
What medical conditions qualify for Dupixent lawsuits?
The primary qualifying condition is cutaneous T-cell lymphoma (CTCL) and its variants:
Mycosis fungoides: The most common form of CTCL, characterized by patches, plaques, or tumors on the skin. Accounts for approximately 50% of all CTCL cases.
Sézary syndrome: An aggressive form of CTCL involving widespread red, itchy rash and cancerous cells circulating in the blood. Represents about 5% of CTCL cases but has worse prognosis.
Primary cutaneous CD30+ lymphoproliferative disorders: Including lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma.
Other cutaneous lymphomas: Some cases of primary cutaneous peripheral T-cell lymphoma or other rare subtypes may qualify if medical evidence supports causation.
Diagnosis must be confirmed through:
Skin biopsy showing malignant T-cell infiltration.
Immunohistochemistry testing identifying specific T-cell markers.
Flow cytometry or T-cell receptor gene rearrangement studies if blood involvement is suspected.
Imaging studies (CT, PET scans) to stage the disease.
Comprehensive pathology reports are critical to establishing a valid claim.

How long do I need to have used Dupixent to qualify?
Most Dupixent lawsuits require a minimum of three months of continuous or cumulative use.
This threshold is based on the time needed for the drug to exert immunomodulatory effects that may trigger lymphoma development.
However, some cases with shorter exposure may still qualify if:
Medical evidence demonstrates rapid onset of CTCL symptoms after Dupixent initiation.
Genetic or immunologic testing suggests increased susceptibility to drug-induced lymphoma.
Expert medical testimony supports causation despite shorter exposure.
Longer duration of Dupixent use generally strengthens causation arguments.
The 2023 JAMA Dermatology study found that cancer risk increased with cumulative exposure, with the highest risk among patients using Dupixent for 12 months or longer.
If you used Dupixent for any period and developed CTCL, consult with an attorney to evaluate your specific case.
Documentation of prescription dates, refill records, and pharmacy records will help establish your exposure timeline.
Can I file a lawsuit if I'm still using Dupixent?
Yes, you can file a lawsuit even if you are currently using Dupixent.
Active treatment does not disqualify you from pursuing legal action.
However, you should consult with your physician before making any changes to your medication regimen.
Suddenly discontinuing Dupixent without medical supervision may cause your underlying condition (eczema, asthma, etc.) to flare.
Your attorney will work with your medical providers to ensure your health needs are prioritized.
In some cases, your doctor may recommend switching to alternative treatments if Dupixent-related cancer risk outweighs therapeutic benefits.
Filing a lawsuit while still on Dupixent may actually strengthen your claim by demonstrating:
You have no safer alternative treatment options available.
The severity of your underlying condition required continued use despite known cancer risk.
You suffered damages even while attempting to manage your condition.
Your attorney can advise on the best legal and medical strategy for your situation.
What if my cancer is in remission?
You may still qualify for a lawsuit even if your CTCL is currently in remission or has been successfully treated.
Past diagnosis and treatment constitute compensable damages regardless of current disease status.
Factors supporting your claim include:
Medical expenses incurred for diagnosis, treatment, and monitoring.
Lost wages during treatment and recovery periods.
Pain and suffering experienced during active disease and treatment.
Ongoing medical surveillance requirements (periodic skin exams, imaging, blood tests).
Risk of cancer recurrence requiring lifelong monitoring.
Long-term side effects from chemotherapy, radiation, or other treatments.
Psychological trauma from cancer diagnosis and fear of recurrence.
Many CTCL patients achieve remission but face years of follow-up care and uncertainty about recurrence.
These ongoing impacts are compensable in Dupixent lawsuits.
Additionally, some settlement structures may include provisions for future medical monitoring or compensation if cancer recurs.
Understand Dupixent settlement amounts
What documentation do I need to prove eligibility?
Strong documentation is essential to establish your Dupixent lawsuit eligibility:
Medical records:
Dupixent prescription records showing start date, dosing, and duration.
Dermatology or allergy/immunology notes documenting treatment rationale.
Pharmacy records confirming Dupixent fills and refills.
Diagnostic documentation:
Skin biopsy reports with pathology findings confirming CTCL diagnosis.
Immunohistochemistry results identifying T-cell markers.
Staging studies (imaging, blood work) determining disease extent.
Oncology or hematology consultations.
Treatment records:
Records of all cancer treatments received (chemotherapy, radiation, phototherapy, etc.).
Hospital admission records if treatment required hospitalization.
Prescription records for cancer-related medications.
Financial documentation:
Medical bills and explanation of benefits (EOB) statements.
Pay stubs or employer documentation of lost wages.
Tax returns showing income before and after diagnosis.
Receipts for out-of-pocket expenses (travel to treatment, co-pays, etc.).
Personal documentation:
Symptom journals documenting progression of skin symptoms.
Photographs of skin lesions, rashes, or tumors.
Testimony from family members about impact on quality of life.
Your attorney will help gather and organize these documents to build the strongest possible case.

Are there age restrictions for filing a lawsuit?
There are no specific age restrictions for filing a Dupixent lawsuit.
Both adults and children who developed CTCL after Dupixent use may qualify.
However, age impacts certain aspects of the claim:
Minor children:
Parents or legal guardians file on behalf of children under 18.
Damages may include impaired growth and development, psychological impact, and loss of normal childhood activities.
Future earning capacity claims may be more speculative but potentially substantial given longer life expectancy.
Elderly patients:
No upper age limit prevents filing.
Damages may be reduced based on shorter life expectancy and limited remaining work years.
However, pain and suffering, loss of quality of life, and medical expenses remain fully compensable.
Young and middle-aged adults:
Typically command higher settlement values due to longer life expectancy and greater lost earning potential.
Career disruption and inability to advance professionally are significant damages.
Age also affects statute of limitations calculations in some states.
Minors may have extended filing deadlines that begin when they reach age 18.
Consult with an attorney to understand deadlines specific to your jurisdiction.
Can family members file if the patient died?
Yes, surviving family members can file wrongful death claims if a loved one died from CTCL caused by Dupixent.
Eligible family members typically include:
Spouses: Can recover loss of companionship, support, and consortium.
Children: Can claim loss of parental guidance, care, and financial support.
Parents: May file on behalf of deceased minor children or, in some states, adult children.
Personal representatives: Estate executors or administrators can file on behalf of the deceased's estate.
Wrongful death damages may include:
Funeral and burial expenses.
Medical expenses incurred before death.
Loss of financial support the deceased would have provided.
Loss of companionship, love, and guidance.
Pain and suffering experienced by the deceased before death (estate claim).
Wrongful death cases often command higher settlement values than non-fatal injury claims.
However, statutes of limitations for wrongful death claims are often shorter than for personal injury (1-2 years in many states).
It is critical to consult with an attorney immediately after a Dupixent-related death to preserve legal rights.

What if I have pre-existing medical conditions?
Pre-existing medical conditions do not automatically disqualify you from filing a Dupixent lawsuit.
However, they may complicate causation arguments.
Common scenarios:
Pre-existing skin conditions (eczema, psoriasis):
This is expected since Dupixent is prescribed for these conditions.
The key question is whether CTCL represents a new, distinct condition caused by Dupixent rather than progression of the underlying disease.
Pathology reports and expert testimony are critical to distinguish drug-induced lymphoma from coincidental development.
History of other cancers:
Prior cancer history does not necessarily bar a claim but may reduce settlement value.
Medical experts will evaluate whether Dupixent exposure increased risk or accelerated lymphoma development.
Immunosuppression or autoimmune conditions:
Some conditions increase baseline lymphoma risk.
Expert analysis is needed to apportion causation between Dupixent and other risk factors.
Your attorney will work with medical experts to establish that Dupixent was a substantial contributing factor to your CTCL diagnosis, even if other risk factors existed.
Comparative fault or apportionment may reduce settlement amounts but rarely eliminates claims entirely.
What disqualifies someone from filing?
Certain factors may disqualify you from participating in Dupixent litigation:
Bankruptcy filing: Active bankruptcy proceedings complicate asset recovery. Consult with both bankruptcy and personal injury attorneys.
Felony convictions: Some settlement programs exclude individuals with felony records. Specific exclusions vary by jurisdiction and settlement structure.
Statute of limitations expired: Filing after the legal deadline bars your claim. Deadlines vary by state (typically 1-3 years from diagnosis).
Lack of medical documentation: Inability to prove Dupixent use or CTCL diagnosis through medical records makes claims difficult or impossible.
No causation: If medical evidence shows CTCL predated Dupixent use or was clearly caused by other factors, claims may not be viable.
Prior settlement or release: Signing a release or accepting settlement for the same injuries bars future claims.
Even if some disqualifying factors exist, consult with an attorney before assuming you cannot file.
Exceptions and workarounds may be available depending on your specific circumstances.
Time is limited. Statutes of limitations may bar your claim if you wait.
