Dupixent Injury Attorneys

Dupixent Lawsuit AttorneyDupixent is a widely used medication that is prescribed for eczema, asthma, and other conditions that cause inflammation of the body. It affects the immune system by blocking the neural pathways involved in inflammation. A number of lawsuits have been filed against Sanofi and Regeneron after patients have allegedly been harmed by taking Dupixent. The lawsuits allege that the drug manufacturers failed to adequately warn patients and their doctors that the medication potentially causes or accelerates cutaneous T-cell lymphoma (CTCL). This is a rare form of non-Hodgkin lymphoma.

According to the United States Judicial Panel on Multidistrict Litigation, “Most plaintiffs used the prescription biologic medication Dupixent, which is commonly prescribed to treat atopic dermatitis, 1 and were later diagnosed with Cutaneous T-cell Lymphoma (CTCL). Other plaintiffs are the spouses or survivors of Dupixent users who were diagnosed with CTCL. Plaintiffs each allege that Dupixent caused them, their spouse, or the decedent to develop CTCL (or that Dupixent accelerated a preexisting CTCL).” If you or a loved one has developed CTCL after taking Dupixent, you may have legal recourse. Our team of experienced personal injury attorneys at GLK Law is here to help you. We can evaluate the unique facts of your case free of cost and let you know if you have a claim that can be pursued.

What Is Cutaneous T-Cell Lymphoma?

Cutaneous T-Cell Lymphoma, or CTCL, is a rare type of cancer that affects a person’s T-cells. Unlike a number of cancers that appear internally, CTCL is often first spotted on a patient’s skin. The early stages of CTCL can often look like eczema, rashes, psoriasis, and other skin conditions.


Because it is possible for CTCL to mimic eczema and other common skin conditions, patients may be treated for eczema for several months before doctors finally conduct a biopsy of the affected tissue. By the time a biopsy is taken, a patient may already have developed lymphoma.

Liability for Injuries Caused by Dupixent

Drug manufacturers have a legal obligation to ensure that their products are reasonably safe. They must complete extensive clinical trials to determine their drugs are safe for all of the groups that will likely be using them. These companies must also warn patients and their doctors about known or reasonably suspected dangers associated with the medication. There are a number of potential claims that could be used in any lawsuit against the manufacturers of Dupixent.


  • Manufacturers may have failed to warn physicians about the risk of CTCL.
  • Manufacturers may have failed to update labels as safety concerns with the medication became apparent.
  • Manufacturers may have failed to adequately study all the long-term risks associated with their product.
  • Manufacturers may have failed to warn that CTCL may resemble eczema and other skin conditions.
  • Manufacturers may have marketed Dupixent as safe and effective without discussing the risk of cancer.


When assessing whether or not any drug manufacturer could potentially be liable for injuries involving their products, the small details really matter. It matters whether or not the manufacturers were aware of studies that suggested a link between their medication and CTCL. Product liability claims are typically pursued as a strict liability offense. In other words, manufacturers can be liable if their product is defective, even if they exercised a great deal of care to avoid causing harm.

What Are the Major Issues With Dupixent?

According to lawsuits against the drug manufacturers responsible for Dupixent, there is a link between the drug and CTCL. The manufacturers of the drug either knew or should have known about this link and failed to properly warn patients and their doctors. What follows are three of the major issues with the drug as outlined by recent litigation.


  • Masking: Dupixent may reduce visible inflammation associated with underlying skin conditions. This can lead to situations where a serious underlying skin condition may appear improved. Accordingly, doctors may fail to perform biopsies and other medical tests as lymphoma remains undiagnosed.
  • Acceleration: Several lawsuits have claimed that Dupixent may worsen or even accelerate a patient’s undiagnosed CTCL. This can cost patients critical time that they would have needed to treat the illness.
  • Delayed Diagnosis: The symptoms of CTCL can often resemble eczema and other skin conditions. This can lead to doctors mistaking their patient’s CTCL for those skin conditions.


It is vital that patients and doctors are aware of the risks associated with any medication. This allows all parties involved to make a decision. No one can make informed decisions when the clinical risks associated with medications are hidden from them.

Who Is Able to Qualify for the Dupixent Lawsuit?

Any person who has taken Dupixent and been diagnosed with CTCL or another T-cell lymphoma may be entitled to damages through a civil action. As the litigation against Sanofi and Regeneron continues to move forward, it has become more clear who may be able to qualify to pursue a lawsuit. What follows below are a few of the qualifying factors related to pursuing a lawsuit after taking Dupixent.


  • The plaintiff used Dupixent before they were diagnosed with CTCL.
  • Dupixent was prescribed by a doctor to treat eczema or other approved skin conditions.
  • The plaintiff was diagnosed with CTCL or another T-cell lymphoma.
  • The plaintiff is the surviving spouse of a person who was diagnosed with CTCL or another T-cell lymphoma.
  • The plaintiff experienced worsening conditions after taking Dupixent.
  • The plaintiff required chemotherapy or related care to treat their CTCL or related condition.


If you have been taking Dupixent, it is important to follow up with a doctor who can evaluate whether or not you may be suffering from CTCL or another T-cell lymphoma. Seeking treatment and follow-up care is extremely important with any diagnosis of CTCL. An attorney can examine the unique facts of your case and let you know if you qualify for a Dupixent lawsuit.

How an Attorney Can Help After Being Harmed by Dupixent

It can be hard to know where to begin if you were diagnosed with CTCL or another serious medical condition after taking Dupixent. These kinds of cases can be enormously complex and often involve poring over medical records, prescription timelines, and clinical trials. An attorney can help examine the unique facts of your case and help determine if you have a legal claim that can be pursued. There are many other ways that an attorney can be enormously helpful after any potential injury involving Dupixent.


  • An attorney can review your prescription for Dupixent and all related medical records to help evaluate the strength of your case.
  • An attorney can build a timeline of your symptoms and show how medical doctors and the manufacturers of Dupixent acted negligently.
  • An attorney can work with medical experts to help determine if Dupixent may have masked, accelerated, or worsened your CTCL.
  • An attorney can handle all communications with defense lawyers and insurance providers.
  • An attorney can take into consideration all of the ways that you have been harmed to ensure you are fairly compensated.
  • Drug manufacturers and insurance providers will do everything in their power to deny liability after they release a drug that harms a patient.


Our attorneys at GLK Law can take steps to ensure that your rights are protected at every stage of the legal process. There is absolutely no upfront cost associated with hiring an attorney to review your case. We work entirely on a contingency fee basis and only get paid if they are able to successfully resolve your claim.

Getting Legal Help After Being Diagnosed With Cutaneous T-Cell Lymphoma

We at GLK Law were very concerned to hear about the safety issues with Dupixent. The Food and Drug Administration should consider a recall and other safety measures to help protect the public. Patients and doctors need to be made aware of the safety issues with any drug that they are considering. When a drug manufacturer fails to take reasonable measures to protect the public, they can be held accountable through a civil claim.
